Shape and its orientation on outer roller 50 of seat 81 can promote the second bottom guide track 20 from the level and smooth of seat 81 and predictable disengaging, to start to make the second blind 24 extend.Shape and the orientation of seat 81 can allow bottom guide track 20 vertically to depart from seat 81, and this make use of the gravity on relatively heavier bottom guide track 20.The substantially tangent orientation of seat 81 on outer roller 50 can help in this.When the second blind 24 is extended and is retracted back through slit 76, the lower free edge (limited by the marginal portion 80 of the second housing 56 of outer roller 50) of slit 76 can be bent or become round, advances smoothly above marginal portion 80 to allow the second blind 24.

Second bottom guide track 20 can be slender member, and slender member has relatively high quality, and defines the groove extending the lower limb receiving and keep the second blind 24 along its length.The lower limb of the second blind 24 can be remained in the groove of bottom guide track 20 by the insert 82 in the ruffle by being positioned in the lower limb being formed in the second blind 24.When the second blind 24 is in advanced position, the part of the profile of the second bottom guide track 20 can substantially with the mating shapes of the seat 81 be formed in outer roller 50, to conform to shape.

With reference to figure 7 to Figure 11, the first blind 22 can be coupled to outer roller 50 and can reel around outer roller 50.The top edge of each in front piece 30 and rear portion sheet 34 can be attached to outer roller 50 by circumferentially spaced position.Between the front side that the rear side of roller 50 is positioned in roller 50 and the side, street of the architectural opening associated, first blind 22 can by the rear side winding around outer roller 50 or from its expansion (among Fig. 8-Figure 11, the rear side of roller 50 is to the right).Usually, the rotation of outer roller 50 on first direction (in Fig. 8-Figure 11 be counterclockwise) makes the first blind 22 bounce back by it to be wound to the position of side of the architectural opening of contiguous association or more side (such as top side) around outer roller 50, and the rotation of outer roller 50 second, on rightabout makes the first blind 22 extend across on whole opening (such as to bottom side).

Still with reference to figure 7 to Figure 11, the second blind 24 can be coupled to interior roller 48 and can reel around interior roller 48.As previously discussed, the top edge of the second blind 24 can be attached to interior roller 48.Between the front side that the rear side of roller unit 46 is positioned in roller unit 46 and the side, street of the architectural opening associated, second blind 24 can by the rear side winding around roller unit 46 or from its expansion (among Fig. 8 to Figure 11, the rear side of roller unit 46 is to the right).Usually, the rotation of interior roller 48 on first direction (in Fig. 8 to Figure 11 be counterclockwise) makes the second blind 24 bounce back by it to be wound to the position of side of the architectural opening of contiguous association or more side (such as top side) around interior roller 48, and the rotation of interior roller 48 second, on rightabout makes the second blind 24 extend across on whole opening (such as to bottom side).

Hereinafter referring to figs. 1 to Fig. 5 and Fig. 7 to Figure 11, the operation of shelter is described.As shown in Fig. 1 and Fig. 7, the first blind 22 and the second blind 24 are in the position bounced back completely, and are hidden in head rail 14.In this configuration (see Fig. 7), the second blind 24 is fully reeled by around interior roller 48, and the first blind 22 is fully reeled by around outer roller 50.In some instances, the part defining top limit stop of the first bottom guide track 18 engagement top guide rail 14.

Extend from head rail 14 to make the first blind 22, user can actuating operations mechanism 40 cause interior roller 48 to rotate bearing of trend (being clockwise in Fig. 8 to Figure 11) is upper, this then cause outer roller 50 at least partly because the weight of the first bottom guide track 18 applies downward power to the first blind 22 in the upper rotation of bearing of trend (being clockwise in Fig. 8 to Figure 11).When the first blind 22 is extended the rear portion of outer roller 50, outer roller 50 as one man rotates with interior roller 48 substantially.The side that two roller unit 46 controls the rotation of interior roller 48 user substantially rotates up.

With reference to figure 2 and Fig. 8, first blind 22 is in closedown or pack up in configuration the rear portion being extended outer roller 50, in closedown or pack up in configuration, front piece 30 and the relatively closed together and blade 38 of rear portion sheet 34 vertically extend in approximate coplanar, the relation that adjoins with front piece 30 and rear portion sheet 34.Once the first blind 22 is launched from outer roller 50 substantially, outer roller 50 continuation in the direction of extension rotates and front piece 30 and rear portion sheet 34 is relative to each other vertically moved substantially, so that blade 38 is displaced to open position (Fig. 3 and Fig. 9) from fastening position (Fig. 2 and Fig. 8).The front portion of bottom guide track 18 can be increased the weight of to exceed, to contribute to opening completely of blade 38 in the rear portion of the first bottom guide track 18.

With reference to figure 3 and Fig. 9, shelter 10 is shown having the first blind 24 be in complete extended position, and its Leaf 38 is in opens or launch in configuration.In this position, front piece 30 and rear portion sheet 34 by and the blade 38 flatly interval that essentially horizontally extends betwixt, and front piece 30 and rear portion sheet 34 can be arranged on identical At The Height with the attachment point 62 of outer roller 50.In fig .9, such as, the direction can be known as at 4 o'clock and 8 o'clock in the position of attachment point 62, and be arranged on and level place substantially the same each other.From the direction shown in Fig. 9, rotation in any direction causes front piece 30 and rear portion sheet 34 to move towards each other to outer roller 50, and causes the aligning that blade 38 reorientation becomes more vertical.

When the first blind 22 is launched completely from outer roller 50, the slit 76 in outer roller 50 is oriented in head rail 14 rotatably, makes the bottom guide track 20 of the second blind 24 when interior roller 48 further rotates in the direction of extension can vertically depart from seat 81.When the tension force in the second blind 24 reduces because the continuation in the direction of extension of interior roller 48 rotates, orientation tangent substantially and the generallyperpendicular position with the seat 81 of the basal wall 84 (see Figure 10 and Figure 11) of Relative vertical allow the weight of the second bottom guide track 20 that bottom guide track 20 is offed normal from outer roller 50.Operating mechanism 40 can comprise brakes, brakes by be operationally couple to interior roller 48 with limit the second blind 24 and undesirable movement downwards of therefore the first blind 22.

In order to make the second blind 24 extend, operating mechanism 40 is activated by additionally by user, to be rotated in the direction of extension by interior roller 48.Between the extended peroid of the second blind 24 (see Fig. 4 and Figure 10), because the weight of the first blind 22 and the weight of the first bottom guide track 18 maintain the position of rotation of outer roller 50 when not having positive lock, outer roller 50 and the first blind 22 can keep static.In some instances, as hereinafter discuss, positive lock can be used to the rotation preventing the outer roller 50 when the first blind 22 extends completely.Go out as shown in Figures 10 and 11, between the extended peroid of the second blind 24, the slit 76 be limited in outer roller 50 can be guided backward, and essentially horizontally can be aimed at by with the axis of rotation 52 (see Fig. 6) of interior roller 48 and outer roller 50.In other words, the second blind 24 can launch the rear side leaving interior roller 48 and outer roller 50.

Between the extended peroid of the second blind 24, interior roller 48 rotates relative to outer roller 50 when accessory 64 and restriction nut 68 support the associated end of interior roller 48.When interior roller 48 rotates in the direction of extension, the second blind 48 when it extends through the slit 76 be formed in outer roller 50 by from the unwinding of interior roller 48.The rotation in the direction of extension of interior roller 48 makes restriction nut 68 move along stop screw 66 towards bottom limit stop.

With reference to figure 5 and Figure 11, be all in the first blind 22 and the second blind 24 in complete extended position both shelter 10 is shown having, its Leaf 38 is in opens or launches in configuration.In this position, front piece 30 and rear portion sheet 34 by and the blade 38 flatly interval that essentially horizontally extends betwixt.Second blind 24 can be shading blind and suppress light to pass the second blind 24, and therefore through the first blind 22.When the second blind 24 is fully extended (see Fig. 5 and Figure 11), the second blind 24 can offset backward from the first blind 22, but jointly can extend in length and width together with the first blind 22.In order to control the light quantity through the first blind 22, the second blind 24 can be return in head rail 14 and to reel around roller 48 in two roller unit 46.

When the second blind 24 is in (minimum extension) in the position extended completely, restriction nut 68 can be positioned in (see Fig. 6) on stop screw 66 and engage with the lower limit stop be formed on stop screw 66, further rotates to prevent interior roller 48.Stop screw 66 can also comprise limit stop to limit the upper limit of shelter 10.Alternately, when the first blind 22 is fully extended the upper limit stop being used as shelter 10, the bottom guide track 18 of the first blind 22 can the part of engagement top guide rail 14.

Any some place during extension process, user can shut-down operation mechanism 40 or make the direction of operating mechanism 40 contrary, the first blind 22 and the second blind 24 to be moved in desired location.In the example comprising motorization shelter 10, pre-programmed order can be used to control motor 44 and the position therefore controlling the first blind 22 and the second blind 24.First blind 22 and the second blind 24 can move in predetermined blind position by order motor 44 by order, and the primary importance that such as the first blind 22 and the second blind 24 bounce back completely, the first blind 22 extend and the 3rd position that extends completely of the second place that bounces back completely of the second blind 24 and the first blind 22 and the second blind 24 completely.Order can be transferred to motor 44 by remote control unit 46.

The retraction of the first blind 22 and the second blind 24 can be completed when compared with above-described extension order in reverse order, such as follows the order of Figure 11 to Fig. 8 substantially.In Fig. 5 and Figure 11, the first blind 22 and the second blind 24 are configured to be in the position extended completely.When both the first blind 22 and the second blind 24 are all in the position extended completely, restriction nut 68 (see Fig. 6) can be engaged by with the lower limit stop that can be formed on stop screw 66.Operating mechanism 40 from the actuating (such as by executive component 42 and/or motor 44) of this position restriction nut 68 axially moved away from lower limit stop and the retraction process of shelter 10.Retraction process relates generally to the actuating of operating mechanism 40, first to make interior roller 48 in the upper rotation of retraction direction (being counterclockwise in fig. 11) to make the second blind 24 bounce back, and when the second blind 24 bounces back completely, outer roller 50 is above rotated to make the first blind 22 retract on outer roller 50 in retraction direction (being counterclockwise in fig. 11) subsequently.This order further describes hereinafter.

In order to make the second blind 24 from the complete extended position retraction of Fig. 5 and Figure 11, user's actuating operations mechanism 40 is to cause interior roller 48 in the upper rotation of retraction direction (being counterclockwise in Fig. 8 to Figure 11), this then the second blind 24 is reeled around interior roller 48, and the second bottom guide track 20 is upwards raised along the rear surface of the rear portion sheet 34 of the first blind 22.During the retraction of the second blind 24, interior roller 48 rotates relative to outer roller 50 when accessory 64 and restriction nut 68 support the associated end of interior roller 48.When interior roller 48 rotates in retraction direction, the second blind 24 is winding to when it is pulled through the slit 76 be formed in outer roller 50 on interior roller 48.The rotation of interior roller 48 in retraction direction makes the opposing end portions of restriction nut 68 along stop screw 66 towards stop screw 66 move.Same during the retraction of the second blind 24, because the weight of the first bottom guide track 18 and the weight overhanging the part of outer roller 50 of the first blind 22 act on outer roller 50 to suppress the rotation of outer roller 50, the first blind 22 remains on and extends completely, in the position of opening.This allows user between the position extended completely and the position bounced back completely, to move the second blind 24 when not having position or the orientation affecting the first blind 22.

With reference to Fig. 9 and Figure 10 of reverse order, when the second blind 24 is return in outer roller 50 further, the second bottom guide track 20 becomes locates in present 81 securely.When bottom guide track 20 engages the seat 81 of outer roller 50, the driving force of operating mechanism 40 can be passed to outer roller 50 by by the second blind 24.That is, operating mechanism 40 inwardly can apply revolving force by roller 48, and revolving force can transfer to be applied to outer roller 50 by the joint of the bottom guide track 20 in the seat 81 under the tension force effect of the second blind 24.With reference to figure 8 and Fig. 9, when the second blind 24 is wound up on interior roller 48 completely and the second bottom guide track 20 is received in the seat 81 of outer roller 50, outer roller 50 can be driven retraction direction (being counterclockwise in Fig. 8 and Fig. 9) is upper by by operating mechanism 40 by the rotation of interior roller 48 in identical retraction direction.Therefore, when in bottom guide track 20 received present 81 and when retraction force (being counterclockwise in Fig. 8 and Fig. 9) being applied to interior roller 48 by operating mechanism 40, outer roller 50 combines interior roller 48 substantially and rotates.

With reference to figure 8, when outer roller 50 continues to rotate in retraction direction, the first blind 22 reels around outer roller 50.Due to the overhang of the first blind 22 and the weight of bottom guide track 18, under the first blind 22 is be in tension force effect when it reels around outer roller 50.

When the first blind 22 bounces back completely, the first bottom guide track 18 can the part (such as interface) of engagement top guide rail 14, to be used as the top limit stop of two roller unit 46.It is contemplated that, other mechanisms can be utilized to limit top advanced position, comprise the top limit stop be positioned on the stop screw 66 relative with bottom limit stop.Such as, top limit stop can be formed on stop screw 66, and is located by along screw 66, makes nut 68 engagement top limit stop when the first blind 22 bounces back completely.

As explained above, the second blind 24 and subsequently the first blind 22 from complete extended position be retracted in user activate for the retraction of two blinds 22,24 single operation element 42 or motor 44 occur.Stop screw 66 comprises enough length to allow restriction nut 68 and moves from bottom limit stop along screw 66, until arrive top advanced position.It is contemplated that the first blind 22 can by the front side winding around outer roller 42 or from its expansion.To the two roller blind technology helping realize as being applied to the anterior blind structure declined be needed to the subsidiary amendment of structure described herein.

Shelter can comprise locking mechanism, locking mechanism is in the rotation of limit outer roller 50 in complete extended position when the first blind 22, thus guarantees that the first blind 22 to remain in the position extended completely and substantially not by the impact of the rotation of interior roller 48 between the extended peroid of the second blind 24.The primary importance that locking mechanism can rotate at restriction outer roller 50 and allow be movably (such as can pivotable, can translation or other suitable movements) between outer roller 50 second place that rotate.In an example, locking mechanism comprises the locking component being positioned in outer roller 50 outside, and locking component is along the periphery longitudinally translation engage retainer to limit the rotation of outer roller 50 of outer roller 50.In another example, locking mechanism comprises the locking component being positioned in outer roller 50 outside, and locking component is pivoted into and engages with outer roller 50 rotation limiting outer roller 50.

Referring to figs 12 to Figure 27, provide the shelter for architectural opening, shelter uses locking mechanism to carry out the rotation reliably locking outer roller when the first blind 22 extends completely.Except locking mechanism and maintenance clip, the shelter described in Figure 12 to Figure 27 has the characteristic sum identical with the shelter described in Fig. 1 to Figure 11 substantially and operates.Therefore, the aforementioned discussion of the characteristic sum of the shelter described in Fig. 1 to Figure 11 operation should be considered to the shelter being applicable to substantially describe in Figure 12 to Figure 27, except mentioned in the following discussion.The reference number used in Figure 12 to Figure 27 has been increased except 100 except reference number, corresponds to the reference number used in Fig. 1 to Figure 11 substantially, to reflect similar part and assembly.

With reference to Figure 12, shelter 110 comprises the axially movable locking mechanism 186 limiting the rotation of outer roller 50 when the first blind 22 is in complete extended position, and locking mechanism 186 is similar in conjunction with the moveable locking mechanism of the pivotable that Figure 28 to 47 is discussed hereinafter.The rotatable shaft 188 that axially movable locking mechanism 186 can comprise shell 187, axle journal is connected to shell 187 and being threadedly engaged with axle 188 and the nut 189 axially can advanced along axle 188.Although the combined left end cap 126b of axially movable locking mechanism 186 describes, locking mechanism 186 can use in conjunction with right end cap 126a.

With reference to Figure 12, Figure 16 and Figure 18, shell 187 can overhang out from left end cap 126b, and axially extends away from left end cap 126b along the periphery of outer roller 150 towards right end cap 126a.An end 187a of shell 187 can be connected to left end cap 126b removedly by by securing member 190, and contrary, the free terminal 187b of shell 187 can be positioned laterally in the outside of outer roller 150.Shell 187 laterally can be separated enough distances with the periphery of outer roller 150, not disturb the first blind (not shown) reel around outer roller 150 or launch from outer roller 150.Shell 187 laterally can be separated consistent distance with the periphery of outer roller 150.

With reference to Figure 16, Figure 18, Figure 21 and Figure 26, opposite end portions 187a, 187b of shell 187 can comprise the axially extended axle collar 191 and from the outward extending companion flange 192 of the axle collar 191.The axle collar 191 can comprise the inwall 193 (see Figure 22 and Figure 26) defining axis hole 194, axis hole 194 receive rotatable shaft 188 rotatably against the necked part 195 of inwall 193.The inwall 193 of the axle collar 191 can also limit keyhole 196, and axle 188 is axially being inserted shell 187 or allowing the current of rotatable shaft 188 (being formed in the retainer 197 on rotatable shaft 188 specifically) during axle 188 is removed shell 187 by keyhole 196.Each in companion flange 192 can limit fastener hole, and fastener hole is configured to receive the securing member 190 (see Figure 12, Figure 14, Figure 16, Figure 18 and Figure 22) shell 187 being connected to corresponding end cap 126a, 126b.End section 187a, 187b of shell 187 can be mirror images each other, to contribute to shell 187 to be interconnected to left end cap 126a or right end cap 126b.

Continue with reference to Figure 12, Figure 16, Figure 18, Figure 21 and Figure 26, shell 187 can comprise the mid portion 187c that end section 187a, 187b are interconnected.Mid portion 187c longitudinally can extend along the periphery of outer roller 150 with lateral separation relation.The mid portion 187c of shell 187 can comprise pedestal 198 and guide rail 199, and each in pedestal 198 and guide rail 199 crosses over the distance between opposite end portions 187a, 187b at shell 187.The pedestal 198 of shell 187 can limit the retainer in the aperture 200 receiving next-door neighbour's end section 187a, 187b, to allow axle 188 to be closed to traffic during axle 188 rotates relative to shell 187, thus reduces the lateral contour of shell 187.The pedestal 198 of shell 187 can also be included in the ribs 201 of longitudinal extension between end section 187a, 187b, and ribs 201 is strengthened shell 187 and reduced transverse shift or the distortion of the mid portion 187c of shell 187.As shown in Figure 27, ribs 201 can comprise the holder 202 of at least one horizontal expansion, and holder 202 increases the rigidity of the rib 201 of longitudinal extension further.

With reference to Figure 12, Figure 16 to Figure 19, Figure 23 and Figure 26, the axle 188 of axially movable locking mechanism 186 can offset from the axis of rotation 152 of interior roller 148, but in parallel or substantially parallel.Axle 188 can be positioned in the outside of outer roller 150, and longitudinally extends along the periphery of outer roller 150 with spaced relationship.Axle 188 can comprise the necked part 195 be rotatably received within the axle collar 191 of shell 187.The necked part 195 of axle 188 can comprise recessed circumferential area, and circumferential area decreases the contact area (and because this reducing friction) between the area supported 193 and the necked part 195 of axle 188 of the axle collar 191.Axle 188 can comprise threaded section 203, and threaded section 203 extends between the necked part 195 of axle 188 and between the axle collar 191 of shell 187.Retainer 197 can be formed on axle 188 near the end of the threaded section 203 of axle 188.Retainer 197 can extend radially outwardly from axle 188, and can axially align (see Figure 21) with the aperture 200 be formed in the pedestal 198 of shell 187, to make during axle 188 rotates relative to shell 187, retainer 197 passes in and out aperture 200 rotatably.Gear 204 can be non-rotatably attached to an end of axle 188, and can limit center cavity, and center cavity is used for relative to end cap 126b laterally Positioning Gear (and therefore axle 188).

With reference to Figure 12, Figure 16, Figure 18 and Figure 24 to Figure 27, the nut 189 of axially movable locking mechanism 186 to be positioned at least partially in shell 187 and axially to advance along axle 188 in the mid portion 187c of shell 187.Nut 189 is bonded to shell 187, to make when axle 188 rotates nut 189 along axle 188 translation, instead of rotates around it.Nut 189 comprises the body 205 that only part extends around axle 188, and can be called as halfnut 189.In alternative design, nut 189 can extend around the whole circumference of axle 188.

With reference to Figure 24 and Figure 25, nut 189 comprises internal thread 206, and internal thread 206 is from body 205 to inner process and be threadedly engaged the external screw thread of the threaded section 203 of axle 188.In order to maintain the joint of screw thread and limit nut 189 and rotate around axle 188, nut 189 can comprise the alar part 207 of two longitudinal extensions, and alar part 207 is from the body radially outward projection of nut 189.Alar part 207 can comprise axially extended fin 208, fin 208 contacts the relative surface (see Figure 27) of the pedestal 198 of shell 187 slidably, and along the mid portion 187c axially guiding nut 189 of shell 187, reduce the contact area (and because this reducing friction) between nut 189 and shell 187 simultaneously.

One in alar part 207 slit 208 that can limit longitudinal extension, slit 208 receives guide rail 199 at least in part.As shown in Figure 27, the part defining slit 208 of alar part 207 can dock the not homonymy of guide rail 199 slidably.Therefore, the alar part 207 of nut 189 can prevent nut 189 from rotating around axle 188 substantially, thus contributes to nut 189 during axle 188 rotates relative to shell 187 along axle 188 translation.In order to laterally strengthen alar part 207, nut 189 can comprise the rib 209 of horizontal expansion, and rib 209 is positioned in the outside of internal thread 206 and extends between alar part 207.In alternative design, nut 189 and shell 187 can comprise the bonding structure of other correspondences various, axially advance along axle 188 to make the nut 189 when axle 188 rotates relative to shell 187.

As described in, axle 188 makes nut 189 move or translation along axle 188 relative to the rotation of shell 187 substantially.In order to limit the axial range of nut 189, axle 188 can comprise from the outward extending retainer 197 of the periphery of axle 188.When contacting with nut 189, retainer 197 limits substantially or limits the translation of nut 189 relative to axle 188, thus restriction or restrictive axes 188 are relative to the further rotation of shell 187.In order to ensure the firm engagement between nut 189 and respective stop part 197, nut 189 can comprise the docking wall 211 of longitudinal extension, when nut 189 arrives the stop position needed for the first blind 22 corresponding to and extend completely, docking wall 211 interacts with axle 188 retainer.As shown in Figure 24, the end that wall 211 can be formed on the internal thread 206 of nut 189 is docked.

In addition or alternately, the body 205 (can be similar to axially extended sleeve pipe) of nut 189 can dock the companion flange 192 of shell 187, stop along axle 188 translation to make nut 189.The body 205 of nut 189 can by radially with the distance that the spaced peripheral of axle 188 is enough, current in the annular space limited between axle 188 and body 205 to allow axle retainer 197.Axle 188 and nut 189 can comprise two retainers 197 and docking wall 211 respectively, to contribute to the interoperability of locking mechanism 186 and right end cap 126a or left end cap 126b, thus provide the based Robust Design that can adapt to left hand assembly and right hand assembly.

With reference to Figure 15 to Figure 17, axially movable locking mechanism 186 can comprise the gear mechanism or gear train 213 that are positioned in interior roller 148 and outer roller 150 outside.Gear mechanism or gear train 213 can comprise the first gear 215 being non-rotatably couple to outer roller 150, the second gear 204 being non-rotatably couple to axle 188 and with the first gear 215 and the intermeshing idler gear 217 of the second gear 204.Idler gear 217 can be rotatably supported on installing plate 219, and installing plate 219 comprises the axially projecting locator pin 221 (see Figure 17) of end cap 126 from installing plate 219 towards association.Locator pin 221 can be received in end cap 126, to limit the rotation of installing plate 219 relative to end cap 126.

Gear mechanism 213 can be changed by the size according to blind component, weight or other features.In an example, gear mechanism 213 provide between the first gear 215 and the second gear 204 three to one gear ratio.That is, for the revolution each time of outer roller 150, axle 188 completes three revolutions.In an example, the external screw thread per inch of axle 188 has 16 screw threads (or pitch of one inch 1/16).Usually, the length of the threaded section 203 of axle 188 can be excessive relative to the opereating specification of nut 189, can adapt to much different blind length to make axle 188.Therefore, in some instances, nut 189 only interacts with in the retainer 197 on rotatable shaft 188 during operation, and provides another retainer can use together with any one in right end cap 126a or left end cap 126b to make locking mechanism 186.

With reference to Figure 15, gear mechanism 213 is depicted as and associates with left end cap 126b.External gear 204,215,217 is rotatably supported by by the minor axis from left end cap 126b axial projections.Idler gear 217 is positioned in the front of the first gear 215, and the second gear 204 is positioned in the front of idler gear 217, and wherein all three gears 215,204,217 are arranged in the same level of contiguous end cap.Idler gear 217 is positioned in the top of the first gear 215, and the second gear 204 is positioned in the top of idler gear 217.First gear 215 and idler gear 217 can be received in from the edge 223 of end cap 126b axial projections.

With reference to Figure 13, provide head rail parts exploded partial view (except substantially with about except right side members identical with those parts discussed Fig. 6 to Figure 11 illustrate).Parts comprise left end cap 126b, be attached to the non-rotatable stop screw 166 of left end cap 126b, be installed on the area supported of stop screw 166 and relative to its left lining 170b rotated, the part (comprising restriction nut 168) internally receiving stop screw 166 and be installed to interior roller 148 in the projection 167 of left lining 170a and right lining 170b, internally receive in roller 148 outer roller 150 and be attached to the axially movable locking mechanism 186 of left end cap 126b.

With reference to Figure 13, Figure 14, Figure 19 and Figure 20, outer roller 150 can comprise the design of separately housing.Specifically, outer roller 150 can comprise the first housing 154 and the second housing 156.In order to the first housing 154 and the second housing 156 are fixed together and relative to each other maintain required spatial relationship, each in the first housing 154 of outer roller 150 and the second housing 156 can receive axial projections 172a, the 172b (see Figure 14, Figure 18 and Figure 19) of left lining 170a and right lining 170b closely.Outer roller 150 can be couple to lining 170a, 170b by axial projections 172a, 172b, as one man rotates around the axis of rotation 152 of outer roller 150 to make outer roller 150 and lining 170a, 170b.First gear 215 can be non-rotatably fixed to the apparent surface relative to axial projections 172a, 172b of left lining 170b, thus guarantees that the first gear 215 as one man rotates with outer roller 150.In order to further the first housing 154 and the second housing 156 are fixed together, housing 154,156 can be kept clip 225 to clip together (Figure 12 to Figure 13 depicts two maintenance clips, although can use more or less clip when needing housing to be firmly fastened to together) by by least one.As shown in Figure 20, clip 225 is kept can be flexibly fastened on the interlocking limit 227 of the first housing 154 and the second housing 156 around.

With reference to Figure 20, the end section 158,160 of the first housing 154 and the second housing 156 can overlap each other and to extend to by least part of antelabium 233,235 by longitudinal extension in the receive path 229,231 of the longitudinal extension of correspondence that limits.The antelabium 233 of the first housing 158 can be positioned in the end of the second housing 160, the inside at the edge 237 of longitudinal extension, and the antelabium 235 of the second housing 160 can be positioned in the end of the first housing 158, the outside at the edge 239 of longitudinal extension (although this layout can conversely).Keep clip 225 flexibly can be fastened on outer fastener 241,243 in the interlocking limit being respectively formed at the first housing 154 and the second housing 156 around, the first housing 154 and the second housing 156 to be clipped together.

With reference to Figure 14 and Figure 19, the design limiting of the separately housing of outer roller 150 slit 176 of longitudinal extension, slit 176 allows current during the extension of the second blind 24 and retraction of the second blind 24.When the marginal portion 158,160 of the first housing 154 and the second housing 156 is locked together, the distal rim portion 178,180 of relative or second longitudinal extension of the first housing 154 and the second housing 156 is by spaced apart circumferentially from one another and define the slit 176 of longitudinal extension.First housing 154 can be spaced enough distances with the second relative distal rim portion 158,160 of the second housing 156, to allow the current of the second blind 24, but prevents the current of the bottom guide track 20 of the second blind 24.The function of outer roller 150 is identical with the function discussed about Fig. 6 to Figure 11 substantially, and therefore here will no longer repeat for simplicity.

During the operation of shelter, when outer roller 150 make the first shelter 22 extend across on whole architectural opening time, first gear 215 drives idler gear 217, idler gear 217 transfers driving second gear 204, second gear 204 makes nut 189 axially traversing towards bottom end position along axle 188.Once nut 189 arrives bottom end position (bottom end position can be limited by the retainer 197 on axle 188), the further rotation of nut 189 restrictive axes 188 on the bearing of trend of the first blind 22, this then inhibit outer roller 150 further rotating in the direction of extension.When outer roller 150 is limited in bearing of trend further rotates and the first blind 22 is launched by the periphery from outer roller 150, second blind 24 can be launched by from interior roller 148, through the slit 176 in outer roller 150, and extend across on whole architectural opening.When interior roller 148 rotates between the extended peroid of the second blind 24, inner restriction nut 168 as one man rotates with interior roller 148 and axially advances towards the bottom end retainer be formed on non-rotatable stop screw 166 along stop screw 166.When the second blind 24 be fully extended across on whole architectural opening to limit the bottom stop part of two roller unit 146 time, inner stop screw 166 contacts bottom end retainer substantially.

During shelter bounces back from complete extended position, the slit 176 limited between the marginal portion 178,180 that interior roller 148 pulls the second blind 24 to be passed in the relative longitudinal extension of the housing 154,156 of outer roller 150, and make the second blind 24 around the periphery winding of interior roller 148 until the periphery of bottom guide track 20 seating outer roller 150 of the second blind 24.During the second blind 24 bounces back, the weight of the bottom guide track 18 of the first blind 22 makes lining 170a, 170b maintain inactive state, and therefore interior roller 148 rotates relative to lining 170a, 170b and outer roller 150.

Once take one's seat, turning moment is passed to outer roller 150 from interior roller 148 by the bottom guide track 20 of the second blind 24, thus outer roller 150 is rotated in retraction direction and the first blind 22 is reeled around the periphery of outer roller 150.Interior roller 148 and outer roller 150 continue to rotate in retraction direction, until the bottom guide track 18 of the first blind 22 touch can by the top limit stop associated with one or two end cap 126, retracted in the position that bounces back completely at this some place shelter.During the rotation of interior roller 148 in retraction direction, inner restriction nut 168 is along the traversing bottom stop part away from the second blind 24 of the non-rotatable stop screw 166 in interior roller 148.During the rotation of outer roller 150 in retraction direction, external nut 189 is along the traversing bottom stop part away from the first blind 22 of rotatable shaft 188.

With reference to Figure 28 to Figure 47, provide the shelter for architectural opening, shelter comprises pivotable locking mechanism.Except pivotable locking mechanism and multi-piece type outer roller, the shelter described in Figure 28 to Figure 47 has the characteristic sum identical with the shelter described in Fig. 6 to Figure 27 substantially and operates.Therefore, the aforementioned discussion of the characteristic sum of the shelter described in Fig. 6 to Figure 27 operation should be considered to the shelter being applicable to substantially describe in Figure 28 to Figure 47, except mentioned in the following discussion.The reference number used in Figure 28 to Figure 47 has been increased except 100 except reference number, corresponds to the reference number used in Figure 12 to Figure 27 substantially, to reflect similar part and assembly.

With reference to Figure 28 to Figure 34, interior roller 248 is substantially cylindrical in shape, and forms the retaining member being used for the top of the second blind 24 to be fixed to the upper.As mentioned above, interior roller 248 is positioned in the inside of outer roller 250 to limit two roller unit, and in this example, two rollers 248,250 are coextensive around identical axis of rotation 252.The top edge of the second blind 24 is attached to interior roller 248, and the lower limb of the second blind 24 to be received in the slit be formed in the second bottom guide track 220 and to remain in slit by insert 282, and insert 282 is positioned in the ruffle on the bottom margin being formed in the second blind 24.Can use other attachment structures that bottom guide track 220 is attached to the second blind 24.

Continue with reference to Figure 28 to Figure 34, the second bottom guide track 220 is slender members, and slender member has relatively high quality, and defines the slit extending the bottom margin receiving and keep the second blind 24 as mentioned above along its length.Second bottom guide track 220 has leg-of-mutton cross section substantially, when the second blind 24 is in advanced position, the part of the second bottom guide track 220 substantially with the mating shapes of the seat 281 be formed on outer roller 250, to conform to shape.As described in more detail below, actuator edge 247 is limited at an end of the second guide rail 220, and engaging locking mechanisms 286 is disengaged with outer roller 250 to make locking mechanism 286.

Outer roller 250 is generic cylindrical in this example, and defines the some features in its circumferential wall.Outer roller 250 defines longitudinal center's axis 252, and outer roller 250 rotates around longitudinal center's axis 252, and interior roller 248 also by around longitudinal center's axis 252 coextensive locate.Form pair of channels 262 to receive and to fix the top of the first blind 22, each wherein in insert 264 is positioned in the ruffle be formed in each top, and insert 264 is for keeping the top in respective channel 262.As mentioned below, the length along outer roller 250 forms the anchor groove 245 locking bearing for receiving roller.Length along outer roller 250 forms slit 276, and slit 276 is communicated with the inside that can be formed pipe of outer roller 250.The either side of slit 276 is formed recessed seat 281.As described below, the second blind 24 is through slit 276 and extends and bounce back, and when being in complete advanced position at least one in many objects, is nested in wherein in the second bottom guide track 220 received present 281.Slit 276 is positioned on outer roller 250, with convenient first blind 22 be in its extended position and blade open in configuration time, slit 276 is positioned at the aftermost top of two passages 262 and contiguous rearmost part.

With reference to Figure 28, Figure 29, Figure 46 and Figure 47, two roller unit is rotatably supported between right end cap 226a and left end cap 226b, and operating mechanism 240 is operationally associated to cause it to rotate with interior roller pipe 248.Operating mechanism 240 is anchored to right end cap 226a, and is activated by by executive component 242 as described above in an example.Operating mechanism 240 can comprise in an example and is usually used in window and blocks Planetary Gear Transmission in application.Operating mechanism 240 can comprise interior fittings 264, and interior fittings 264 is rotated by by operating mechanism 240.The size of accessory 264 is configured to be received in interior roller 248, and closely engages the inwall of interior roller 248.When accessory is driven by operating mechanism 240, interior roller 248 is driven into rotation by by interior fittings 264.The right-hand member of the opening of outer roller 250 receives right-hand member roller lid 270a, and right-hand member roller lid 270a comprises the center port with the axially extended axle collar, and center port rotatably receives the axial support surfaces on the shell being formed in operating mechanism 240.When outer roller 250 rotates, area supported is supported when right-hand member roller lid 270a rotates.Interior roller 248 is rotatably received within the axle collar.It is rotatably supported when the right-hand member of interior pipe 248 is driven into rotation by operating mechanism 240 by the axle collar.

As shown in Figure 46, right-hand member 248a, 250a of interior roller 248 and outer roller 250 can respectively with aligned with each other, and the right side edge 24a of the second blind 24 can aim at right-hand member 248a, 250a of roller 248,250.As shown in Figure 47, left end 248b, 250b of interior roller 248 and outer roller 250 can respectively with aligned with each other, and the left side edge 24b of the second blind 24 can aim at left end 248b, 250b of roller 248,250.First blind 22 can be reeled by around outer roller 250, and the edge of the first blind 22 can be aimed at the edge of the end of roller 248,250 and the second blind 24.The aligning at the end of roller 248,250 and the edge of blind 22,24 can reduce or eliminate the light slit between the edge of blind and the respective side of architectural opening.

When the second blind 24 is fully retracted on interior roller 248 and the second end rails 220 is received in the seat 281 of outer tube 250, outer roller 250 is driven into rotation by by interior roller 248.In this case, when interior roller 248 rotates, the second blind 24 is strained the second end rails 220, second end rails 220 interface of transferring between the second end rails 220 and seat 281 and power is applied to outer roller 250.Therefore, outer roller 250 be caused combine in roller 248 rotate.Outer roller 250 does not rotate together with interior roller 248, unless the second blind 24 bounces back completely around interior roller 248.As mentioned above, operating mechanism 240 can be activated by executive component 242 and make the first blind 22 and the second blind 24 as desirably extended by user or bouncing back.Eurypalynous mechanism perhaps when executive component 242 activates for causing interior roller pipe 248 to rotate is acceptable.

Continue with reference to Figure 28 and Figure 29, stop screw 266 is positioned in the inside of interior roller 248, and is operationally fixed to left end cap 226b by screw.Stop screw 266 non rotating.Restriction nut 268 is threadedly engaged by with stop screw 266, and is bonded to the inside of interior roller 248 rotatably, and bond structure allows restriction nut 268 to move along the length of interior roller 248.When interior roller 248 rotates, restriction nut 268 moves along threaded restrictive axes 266, and engages the limit stop (see Fig. 5) defining the bottommost extended position of the second blind 24.The advanced position of the first blind 22 in this example by by limit by the first blind 22 of fully reeling around outer roller 250.In some instances, the part defining this position of the first bottom guide track 18 engagement top guide rail 14.Alternately or in addition, although do not use the top limit stop on stop screw 266 in this example, if need to adopt a top limit stop on stop screw 266.Left end cap 226b as being clear that in Figure 28, Figure 29 and Figure 47 rotatably supports interior roller 248 and outer roller 250.

With reference to Figure 28, Figure 29 and Figure 40, pivot support frame 249 is attached to the inner surface of left end cap 226b, and the annular projection 251 defining centralized positioning and the pillar 253 extended towards right end cap 226a, pillar 253 is pivotally mounted the wheel shaft on it as roller lock 255.Annular projection 251 on pivot support frame 249 is rotatably received within the center port of left outside roller lid 270b, and left outside roller lid 270b itself is received in the left end of the opening of outer roller 250.The axle collar axially extends around the center port of lid 270b, and is used as the area supported of the relative rotation between outer roller 250 with left end support.The left end of the opening of interior roller 248 is rotatably received within the external surface of the axle collar, and the axle collar serves as the area supported rotated relative to the axle collar for roller 248, and rotation carries out under by the selection control action of operating mechanism 240.

Roller lock 255 as shown in Figure 28, Figure 29, Figure 38 and Figure 39 by the pillar 253 (see Figure 40 and Figure 41) be attached to pivotally on pivot support frame 249, and is fixed to pillar 253 (see Figure 41) by by securing member 257.Roller lock 255 is pivotable relative to pivot support frame 249 around the axis limited by pillar 253.Spring member 259 (see Figure 43) is located by the pillar 253 around pivot support frame 249, spring 259 has two supporting legs, a supporting leg engagement roller lock 255 engages with the external surface of outer roller 250 to make roller lock 255 be biased to, and another supporting leg operationally engages the part of left end cap 226b.

With reference to Figure 38 and Figure 39, roller lock 255 comprises the frame plate 261 with central body 263, and extend upper supporting leg 265 and lower supporting leg 267 from body 263, each in supporting leg 265,267 is arranged in the plane identical with central body 263.Upper supporting leg 265 and lower supporting leg 267 with each other in close to extending squarely, and it is contemplated that this relative positioning can be adjusted to the geometry of given specific use as required.The end of lower supporting leg 267 comprises the pin 269 extended orthogonally from plate 261 towards relative end cap, and pin 269 has cylinder form and is relatively short.Such as, pin 269 can not extend the rotation enough far disturbing roller 250.The movement that the length of pin 269 and shape contribute between pin 269 with the actuator edge 247 in the second end rails 220 engages.

Continue with reference to Figure 38 and Figure 39, the end of upper supporting leg 265 rotatably supports relatively long cylinder-shaped bearing 271, and cylinder-shaped bearing 271 extends from upper supporting leg 265 orthogonally towards relative end cap 226a.Bearing 271 is rotatably supported on its opposed ends by the arm 273 by angularly extending with central plate 261.Arm 273 only from the far-end of top support bearing 271, and does not extend many centers exceeding bearing 271.As hereinafter further described, this configuration allows the bottom of bearing 271 along its length unobstructedly and can be received in the anchor groove 245 be formed in outer roller 250, and engages the external surface of outer roller 250 and push down along its surface.

Hereinafter the operation of Primary Reference Figure 30 to Figure 34 to shelter example is described.As shown in Figure 30, the first blind 22 and the second blind 24 are all in extended position, and blade 38 is in and opens in configuration.Concise and to the point with reference to Figure 30, the first blind 22 can be coupled to outer roller 42 and can reel around outer roller 42.The top edge of each in front piece 30 and rear portion sheet 34 can be coupled to gland that inwardly guide, longitudinal extension or rib 275.Gland 275 can be defined through the peripherally ported inner chamber 262 of outer roller 250.Between the front side that the rear side of roller 250 is positioned in roller 250 and the side, street of the architectural opening associated, blind 22 can by the rear side winding around roller 250 or from its expansion (in fig. 30, the rear side of roller is to the right).Usually, the rotation of roller 250 on first direction (be in fig. 30 counterclockwise) makes blind 22 bounce back by it to be wound to the position of side of the architectural opening of contiguous association or more side (such as top side) around outer roller 250, and the rotation of roller 250 second, on rightabout can make blind 22 extend across on whole opening (such as to bottom side).

By the rear portion sheet 30 of the first blind 22 and the abutment 262 of front piece 34 being positioned to be in identical At The Height with outer roller 250, the first blind 22 is maintained in this open position.In fig. 30, such as, the direction can be known as at 4 o'clock and 8 o'clock in the position of these attachment point 262, they are placed to and identical level closer to each other by this.If outer roller 250 rotates in any direction from the direction shown in Figure 30, front piece 30 and rear portion sheet 34 will move towards each other, and reorientation is become more vertical aligning by blade 38.

First blind 22 and the second blind 24 are all in this position in complete extended position wherein, and restriction nut 268 (seeing Figure 28 and Figure 29 substantially) is engaged by with lower limited part.Being retracted in head rail 14 from the actuating of this position makes the second blind 24 such as by the operating mechanism 240 of executive component 242.First operating mechanism 240 makes interior roller 248 counter clockwise direction in fig. 30 to rotate the second blind 24 is bounced back, and when the second blind 24 bounces back completely, outer roller 250 is activated to be retracted on outer roller 250 by the first blind 22 subsequently.This order is at this paper and hereinafter further describe.

As mentioned above and still with reference to Figure 30, interior roller 248 is positioned in outer roller 250 to limit two roller unit 246.Outer roller 250 defines axis of rotation 252, and axis of rotation 252 limited by the part of having of outer roller 250 round-shaped (such as, from 9 o'clock direction to 2 o'clock direction).Interior roller 248 is located to be coextensive with outer roller 250 or to be concentric around the axis 252 identical with outer roller 250.

During the retraction of the second blind 24, interior roller 248 rotates relative to outer roller 250 when the associated end of left roller end lid 270a with the roller in spider collar support 248 in right roller end lid 270b.Outer roller 250 is remained in the position of rotation fixed relative to interior roller 248 by by roller lock 255.Roller lock 255 is oriented as and bearing 271 is biased to by spring 259 be received in (see Figure 28 to Figure 30) in anchor groove 245.This position of bearing 271 inhibits the rotation of outer roller 250.When interior roller 248 rotates in retraction direction, the second blind 24 is winding to when it is pulled through the slit 276 be formed in outer roller 250 on interior roller 248.This retraction rotates and the opposing end portions of restriction nut 268 along stop screw 266 towards stop screw 266 is moved.

The slit 276 that second blind 24 extends through and the seat 281 for receiving the second end rails 220 are positioned in outer roller 250 circumferentially above the attachment point 262 of the rear portion sheet 34 of the first blind 22.The direction at this 3 o'clock of can being known as in fig. 30.Slit 276 is limited by by the relative free edge formed in present 281.Seat 281 is the depressions formed along the length of slit 276, and comprises two outward flanges on the border of the seat 281 circumferentially defining outer roller 250.As institute's orientation in Figure 30, the shape of depression is have corner angle a little generally, wherein the basal wall 284 of the generallyperpendicular orientation joint that allows the Relative vertical between the second bottom guide track 220 and outer roller 250 tangent and disengaging.The location near the rear positions farthest circumferentially of outer roller 250 of seat 281 and slit 276 allows the second bottom guide track 220 during bouncing back, to be pulled the firm reception (see Figure 31 and Figure 32) of going forward side by side when taking a seat in 281 when it vertically upward together with the shape of seat 281.

Shape and its orientation on outer roller 250 of seat 281 promote the second bottom guide track 220 from the level and smooth of seat 281 and predictable disengaging, to start to extend the second blind 24 (position from shown in Figure 32).The shape of seat 281 and orientation allow bottom guide track 220 vertically to depart from seat 281, and this make use of the gravity on relatively heavier bottom guide track 220.Tangent substantially on outer roller 250 of seat 281 is oriented in this and puts enterprising trade association and help.With reference to Figure 35, upper wall 277a from the top of depression down and radially inwardly extend to antelabium 277b, antelabium 277b directly down extends to free edge 277c.This part of seat 281 is the darkest (when measuring from circumference towards the center of outer roller).Lower wall 279a from the bottom margin of depression be shallow angle upwards and upcountry extend, and be transformed into the antelabium 279b of the lower free edge 279c defining slit 276.Lower wall 279a is Relative vertical, and keeps smooth like this in conjunction with upper lip 277b.The lower free edge 279c of slit 276 is bent or becomes round, advances smoothly when the second blind 24 retracts on interior roller 248 to allow the second blind 24 at this superstructure.

Firm engagement in second bottom guide track 220 present 281 contributes to roller and locks 255 consistent actuatings, is disengaged with anchor groove 245 to make bearing 271.With reference to Figure 31, when the second blind 24 is by close to when reeling completely around interior roller 248, the bottom guide track 220 engagement roller lock 255 of the second blind 24, locks 255 to make roller and is disengaged with the outside of outer roller 250.Second bottom guide track 220 is shown in broken lines in Figure 31 and Figure 35.In this position, from the end axially extended actuator edge 247 of the second bottom guide track 220 be formed in the pin 269 that roller locks the lower supporting leg 267 of 255 and contact.When the second bottom guide track 220 is bounced back by the second blind 24 and is drawn into seat 281, actuator edge 247 makes pin 269 move relative to the pivotal line of pillar 253.Pin 269 is radially inwardly moved by relative to interior roller 248, and is circumferentially moved by the pivotal line relative to roller lock 255.Roller lock 255 makes upper arm 265 move around the movement of pillar 253, and this makes bearing 271 start to move up and departs from the joint with anchor groove 245, and this release outer roller 250 rotates (see Figure 32, Figure 36 and Figure 43).

As shown in Figure 42 and Figure 43, actuator edge 247 is extended the end of the contiguous roller lock 255 of the second bottom guide track 220.With reference to Figure 44 and Figure 45, edge 247 is thin bending elements, and element conforms to the curved shape of the bottom side of the second bottom guide track 220 in this example.Edge 247 bends along the size consistent with the bottom side of the second bottom guide track 220, and axially extends away from the second bottom guide track 220.As being clear that in Figure 43, edge 247 extends the distance that the pin 269 be enough on engagement roller lock 255 does not still contact the central plate 261 of roller lock 255.In inside, the rounded outer surface of the recessed surperficial bayonet 269 of fin 247.When the second bottom guide track 220 is bounced back further, pin 269 and fin 247 maintain slip joint.This further movement of the second end rails 220 causes roller to lock 255 further around the pivotal line pivotable of pillar 253, and therefore makes roller lock shaft hold 271 to move out anchor groove 245.

With reference to Figure 32 and Figure 36, when the second blind 24 is return in outer roller 250 further, bottom guide track 220 becomes locates in present 281 securely, and fin 247 makes pin 269 move inward enough amounts to be removed from anchor groove 245 by bearing 271 completely, and this release outer roller 250 rotates.The rotary motion of interior roller 248 is applied to outer roller 250 by the joint of the bottom guide track 220 in the seat 281 under the tension force effect of the second blind 24 by the further actuating of operating mechanism 240.This joint causes outer roller 250 to rotate in conjunction with the rotation of interior roller 248.When outer roller 250 starts to rotate in retraction direction, the pin 269 that the actuator edge 247 on the second bottom guide track 220 and roller are locked on 255 is disengaged.With reference to Figure 33 and Figure 37, roller lock 255 is by biased to cause bearing 271 at the external surface contacting outer roller 250 with the isolated circumferential position of anchor groove 245 by spring 259 upon release.

With reference to Figure 34, when outer roller 250 continues to rotate in retraction direction, the first blind 22 reels around outer roller 250, thus covers anchor groove 245.When roller lock shaft hold 271 along with outer roller 250 continue rotate and close to anchor groove 245 time, roller lock shaft hold 271 by ride over cross over groove 245 the first blind 22 on and above groove 245 pass through.Therefore first blind 22 makes the span of blind 22 extend in the top of groove 245 relatively in tension under being be in tension force effect when it reels around outer roller 250.When only single wrap first blind 22 being positioned at above anchor groove 245, bearing 271 can be pressed in anchor groove 245 a little, but after another rotates completely, bearing 271 rides over the surface of the first blind 22 reeled around outer roller 250 when the interference not from anchor groove 245.

When the first blind 22 continues retraction, it reels many times around outer roller 250, and roller lock shaft holds 271 continues to ride on the external surface of blind 22.Such as when the first bottom guide track 18 contacts the interface on head rail shell, two roller unit 246 arrives top advanced position.It is contemplated that, other mechanisms can be utilized to limit top advanced position, comprise the top limit stop be positioned on the stop screw 266 relative with bottom limit stop.As explained above, an executive component (manually or automatically) that the second blind 24 and the first blind 22 can activate when user the retraction being used for two blinds 22,24 from the retraction of complete extended position, occurs.Stop screw 266 has enough length to allow restriction nut 268 and moves from bottom limit stop, until arrive top advanced position.

If needed, the extension of the first blind 22 and the second blind 24 is realized by with reverse order as described above, such as follows Figure 34 to Figure 30 substantially.Whether this allows user to select only to make the first blind 22 extend or also make the second blind 24 extend (between bouncing back completely and extending completely).Between the first blind 22 extended peroid, user's actuating operations mechanism 240, to cause interior roller 248 to rotate bearing of trend (being clockwise in Figure 34 to Figure 30) is upper, this then cause outer roller 250 to rotate in the direction of extension.In this example, the side that two roller unit 246 controls the rotation of interior roller 248 user rotates up.When the first blind 22 is extended the rear portion of outer roller 250, roller lock shaft holds 271 and rides on the external surface of outer roller 250, until the first blind 22 almost extends completely.In this, the external surface of outer roller 250 exposes.

When outer roller 250 continues to rotate, roller lock shaft holds 271 and rides on the external surface of outer roller 250, until it encounters anchor groove 245.Bearing 271 is positioned in groove 245 by being set to by spring 259 downward bias and suppresses the rotation of outer roller 250, and in allowing, roller 248 continues to rotate (if needed for user).Because roller lock 255 is by the direction upper offset at the external surface facing to outer roller 250, the situation that bearing 271 is not promoting further is moved in anchor groove 245.In this, the first blind 22 is in it across the maximum extended position place on whole opening.It is contemplated that roller lock 255 can be biased by by the device except the spring 259 in these examples.Such as, the top arm 273 of roller lock 255 can be increased the weight of as making roller lock 255 automatically pivotables under the weight effect of top arm 273 as required.Wherein used spring 259, it can be the spring (such as rubber, elastic cord and/or plastics) etc. of line spring, wind spring, elastomeric material.

When the bearing 271 of roller lock 255 sits in anchor groove 245, slit 276 in outer roller 250 is oriented in head rail 14 rotatably, make when the tension force in the second blind 24 is reduced by operating system 240, the bottom guide track 220 of the second blind 24 can vertically depart from seat 281.When the tension force in the second blind 24 is released in advanced position, orientation tangent substantially and the generallyperpendicular position with the seat 281 of the basal wall 284 of Relative vertical allow the weight of the second bottom guide track 220 effectively to make bottom guide track 220 extract out from seat 281.But if user is not intended to make the second blind 24 extend, so the second blind 24 can keep retraction.Operating mechanism 240 can comprise brakes to limit undesirable movement downwards of the second blind 24 or the first blind 22.

In order to make the second blind 24 extend, operating system 240 is activated into required level by additionally by user.When user makes the second blind 24 extend to extreme lower position (maximum extension), restriction nut 268 is positioned on stop screw 266, engages with lower limit stop.Therefore, single stop screw 266 can be used to the upper limit of the first blind 22 limiting the retraction being attached to outer roller 250, and for the lower limit of the second blind 24 of limiting the extension being attached to interior roller 248.

It is contemplated that first blind 22 (it can be identical or different from the first blind 22 shown in Fig. 1 to Fig. 5) of Figure 30 to Figure 34 can be reeled by the front side around outer roller 250 or launch from it.To the two roller blind technology helping realize as being applied to the anterior blind structure declined be needed to the subsidiary amendment of structure described herein.Also it is contemplated that, can on the right-hand member of the head rail of combining with right end cap 226a in conjunction with the roller latch mechanism on the left end of head rail or adopt individually roller latch mechanism and its operate needed for subsidiary element.Equally, the second bottom guide track 220 can have actuator edge 247 on its arbitrary end.
