In one preferred form, the motor 40 is, more particularly, an electric motor and is connected to a source of electrical energy represented via the motor power source 44 by electrical conductors comprising the cable 46. In this embodiment, the motor control 48 is a forward-off-reverse bi-polarity type of threeposition switch, for example, capable of establishing electrical continuity between the motor 40 and the motor power source 44 in the forward position of the motor control 48 with reverse polarity as compared to the polarity of the motor power source 44 when connected to the motor 40 in the reverse position of the motor control 48. Electric motors having drive shafts and constructed to be operated via a forward-offreverseswitch type of motor control interposed between the motor and an electrical power source are well-known in the art and a detailed description of the construction and the operation of the motor, the drive shaft and the switch-type of motor control is not required herein. a

The motor 40 is disposed within the opening 34 of the shaft 18 generally near the end 36 of the shaft 18 and, more particularly, the motor 40 is securedly connected to the shaft 18 via securing bolts 50 threadably inserted through threaded apertures 52 formed] through the shaft 18, one end of each of the securing bolts 50 engaging the motor housing 41 and cooperating to secure the motor 40 in an assembled position connected to the shaft 18 The motor 40 is positioned near the end 36 of the shaft 18 such that, in an assembled position,

the drive shaft 42 extends axially a predetermined distance beyond the end 36 of the shaft 18.

A circular cap 54, having a cap opening 56 formed through a central portion thereof, is removably connected to the end 36 of the shaft 18, more particularly, the cap 54 has a flange 58 formed on the outer periphery thereof extending a predetermined distance generally perpendicularly therefrom and circumferentially thereabout. The outer diameter of the cap 54 formed via the outer peripheral surface of the flange 58 is slightly less than the inner diameter of the axial opening 34 of the shaft 18. In an assembled position, the flange I 58 of the cap 54 is inserted a distance into the opening 34 of the end 36 of the shaft 18 to a position wherein the cap 54 is removably secured to the shaft 18 and the drive shaft 42 extends through the cap opening 56.

In one preferred embodiment, the flange 58 is sized to sealingly engage the wall formed in the shaft 18 via the axial opening 34. In this last-mentioned embodiment, the outer diameter of the cap 54 formed via the outer peripheral surface of the flange 58 is sized to provide a press fit or the like, sealingly engaging the inner peripheral surface formed via the axial opening I 34 in the shaft 18, for example.

A cylindrically shaped plug 60 is disposed within the axial opening 34 generally nearthe end 38 of the shaft 18. A shaft extension 62 is connected to one end of the plug 60 and extends a predetermined distance axially from the central portion of the plug 60. In an assembled condition, the plug 60 is disposed within the opening 34 and positioned therein such that the shaft extension 62 extends a predetermined distance axially beyond the end 38 of the shaft 18. The plug 60 is secured within the shaft 18 via a securing bolt 64 threadably inserted through a threaded aperture 65 formed through a portion of the shaft 18 and intersecting the opening 34 generally near the end 38 of the shaft 18. The securing bolt 64 engages the shaft 18 and the plug 60 securing the plug 60 in an assembled position connected to the shaft 18.

The support assembly 16 includes a pair of support connectors 66 and 68 (the support connectors 66 and 68 sometimes being referred to below as the first support connector 66 and the second support connector 68). The drive shaft 42 of the motor 40 is secured to the support connector 66 and the shaft extension 62 is journally connected to the support connector 68. Thus, in a driven position of the motor 40 when the motor control 48 is positioned in the forward or the reverse position, torque is applied at the drive shaft 42 via the motor 40 causing the motor 40 to rotate relative to the support connector 66 sincethe drive shaft 42 is secured to the support connector 66. The rotation of the motor 40 is imparted to the shaft 18' due to the connection betweenthe shaft 18 and the motor 40 provided via the securing bolts 50, the end 38 of the shaft 18 being journally connected to the support connector 68 via the shaft extension 62 journally connected to thesupport connector 68. The direction of rotation of the shaft 18 is controlled via the position of the motor control 48 in a manner described before.

The support connectors 66 and 68 are each constructed similarly and each support connector 66 and 68 includes a rod member 70, having one end thereof bers 70. Each base member 76 is, more particularly, telescoped about the end of one of the rod members 70, opposite the end of the rod member 70 pivotally connected to the support structure 12, the rod members 70 each being telescoped in a portion of the hollow portion of one of the base members 76. The rod member 70 and the base member 76 of each support connector 66 and 68 are each constructed such that the base members 76 can be telescoped about one of the rod members 70 in a generally downwardly direction 78 and in a generally upwardly direction 80, for reasons which will be made more apparent below.

The support assembly 16 also includes a pair of screw members 82, each screw member 82 having a portion threadedly insertable through one of a plurality of threaded openings 83 formed in the base members 76. The openings 83 are spaced along each base member 76 and the screw members 82 are sized such that each screw member 82 is removably insertable through one of the openings 83in the base members 76 to a position wherein a portion of each screw member 82 intersects the hollow portion of one of the base members 76. The screw members 82 are, more particularly, positioned with the hollow portions of the base members 76 such that a portion of each screw member 76 engages an adjacent portion of one of the rod members 70 limiting the movement of the rod members 70 in a direction 80 and securing each rod member 70 in a predetermined telescoped position within one of the base members 76, the predetermined telescoped position being selectively adjustable by inserting the screw members 82 in selected openings 83, for reasons which will be made more apparent below.

A stop 84 is disposed within the hollow portion of each of the base members 76, each stop 84 being sized and positioned within one of the base members 76 such that a lower portion thereof engages the end of one of the rod members 70 telescoped in the base members 76 limiting the movement of each rod member 70 in a direction 80 and positioning each rod member 70 in a storing position within one of the base members 76, for reasons to be made more apparent below.

The support assembly 16 also includes a pair of brace members 86. One end of each brace member 86 is pivotally connected to a portion of the support structure 12 via a pin 88 and a flange 90, each flange 90 being secured to the support structure 12. The end of each brace member 86, opposite the end thereof which is pivotally secured to the support structure 12, is removably connected to one of the support connectors 66 and 68 and, more particularly, to one of the base members 76. Each brace member 86 is pivotable to a bracing position, as shown in FIGS. 1 and 2, with respect to the support connectors 66 and 68 to prevent the rotation of the support connectors 66 and 68 in a direction generally toward the support structure 12, for reasons to be made more apparent below.

A member 92 is removably secured to the end of each brace member 86, opposite the end thereof which is pivotally secured to the support structure 12. In one form, each member 92 is constructed of an elastomeric material to reduce sliding friction between each member 92 and the base member 76 in engagement therewith.

The support assembly 16 also includes a pair of C- shaped flanges 94, each flange 94 being secured to a portion of the support structure 12 and positioned thereon to receive one of the brace members 86 and one of the support connectors 66 and 68, in one position of each brace member 86 and each support connector 66 and 68. The support assembly 16 is constructed and positioned on the support structure 12 such that each brace member 86 and each of the support connectors 66 and 68 can be pivoted in adirection generally toward the support structure 12 to astored position (shown in dashed-lines in FIG. 2), wherein each brace member 86 and each of the support connectors 66 and 68 is disposed generally adjacent the support structure 12 and removably disposed in one of the C-shaped flanges 94. Each brace member 86 and each of the support connectors 66 and 68 is secured in a stored position within one of the C-shaped flanges 94 by a pin 96.

As shown more clearly in FIG. 3, a block 98 is disposed and secured Within the hollow portion of each base member 76 and disposed generally near the ends thereof, opposite the end telescopingly receiving one of the rod members 70. An opening 100 is formed through each block 98 and, in an assembled position, each opening 100 is aligned with an opening 102 formed through each of the base members 76.

The shaft extension 62, more particularly, journally extends through the opening 102 in the base member 76 of the support connector 68 and through the opening 100 formed through the block 98 secured within the base member 76 of the support connector 68. The end of the shaft extension 62, opposite the end connected to the plug 60, extends a distance beyond the base member 76 and a nut 104 is secured thereon, the nut 104 engaging the base member 76 and retaining the shaft extension 62 in an assembled position journally extending through the openings 100 and 102.

The drive shaft 42, more particularly, journally extends through the opening 102 in the base member 76 of the support connector 66 and through the opening 100 formed through the block 98 secured within the base member 76 of the support connector 66. The end of the drive shaft 42, opposite the end extending from the motor housing 41, also extends through a portion of an opening 106 formed through a shaft support block 108. The shaft support block 108 is securedly connected to the base member 76 of the support connector 66 and the openings 106, 100, 102 and the 'cap opening 56.

A bolt 110 is threadedly disposed through a threaded opening 112 formed through a portion of the shaft support block 108, extending generally transversely to the opening 106 and intersecting a portion of the opening 106. The bolt 110 engages a portionof the drive shaft 42 removably securing the drive shaft 42 in astationary position relative to the shaft support block 108, thereby securedly affixing the drive shaft 42 in a stationary position relative to the support connector 66.

OPERATION OF THE PREFERRED EMBODIMENT The awning control apparatus 10, described in detail above, is constructed to controllingly and uniformly unroll the awning 14 from about the shaft 18, to an extended or operating position, as shown in FIGS. 1 and 2, and to securedly support the awning 14 in that position. The awning control apparatus 10 also controllingly and uniformly rolls the awning 14 about the shaft 18, to a position wherein the awning control apparatus 10 is sccuredly supported in a stored position (as shown in dashed-lines in FIG. 2).

To storingly roll the awning 14 about the shaft 18 and to move the awning control apparatus 10 to a stored position, the operator will initially disengage each brace member 86 from the support connectors 66 and 68, and pivot each brace member 86 in a general direction 114 toward the support structure 12, to a position wherein each brace member 86 is disposed generally adjacent the support structure 12 and within the flange members of the C-shaped flanges 94. The operator will then disengage each screw member 82 from the respective rod member 70 in engagement therewith, and telescope each base member 76 in a generally downwardly direction 78 to a position wherein each of the stops 84 limitingly engage the end of one of the rod members 70, thereby positioning each of the support connectors 66 and 68 in a position to be storingly disposed with respect to the support structure 12.

The motor control 48 is then positioned in the forward position establishing continuity between the motor 40 and the motor power source 44 and positioning the motor 40 in a first driven position. In the first driven position of the motor 40, torque is applied at the drive shaft 42 in a direction causing the motor 40 and the shaft 18 connected thereto to be rotated in a storing direction 30 via the interconnections between the motor 40 and the shaft 18 and between the drive shaft 42 and the support connector 66.

As the shaft 18 is rotated in a storing direction 30, the awning 14 will be storingly rolled about the shaft 18 thereby pivotally moving the shaft 18 and each of the support connectors 66 and 68 in a general direction 116 toward the support structure 12. In the extended position of the awning 14, each of the support connectors 66 and 68 and the shaft 18 are disposed such that the natural gravitational forces tend to pivot the shaft 18 and each of the support connectors 66 and 68 in a general direction 118, the weight of the motor 40 supported within the shaft 18 augmenting the pivotal movement in the direction 118. The pivotal movement of each support connector 66 and 68 and the shaft 18 in a general direction 118 is limited by the awning 14 which is secured to the support structure 12 and the shaft 18.

The pivotal tendency of each support connector 66 and 68 in the general direction 118 causes the weight of each support connector 66 and 68 and weight of the shaft 18 to pull the awning 14 in a direction generally away from the support structure 12, thereby maintaining the awning 14 taut as the awning 14 is storingly rolled about the shaft 18. In this manner, the awning 14 is rolled about the shaft 18 in a more efficient and uniform manner. The motor control 48, in one embodiment, may be ofa variable speed type so that the operator may regulate the speed with which the awning 14 is rolled and unrolled from about the shaft 18, however, in the'preferred embodiment, the motor 40 rotates the shaft 18 at a relatively constant speed, the utilization of the motor 40 resulting not only in an increase in efficiency of operation, but also substantially increasing the uniformity with which the awning 14 is storingly rolled or releasingly unrolled about the shaft 18.

It should also be noted that the motor 40 can be easily stopped to position the awning 14 at various intermediate positions between the extended position and the stored position thereof utilizing the motor control 48, if desired, in some applications. In one embodirne'nt,the motor control 48 is remotely disposed with respect to the motor 40 and the shaft 18 for operating the awning control apparatus 10 from a remote position such as by locating the motor control 48 inside the support structure 12 or on the exterior side wall of the support structure 12 near the awning control apparatus 10, for example.

When the awning 14 has been storingly rolled about the shaft 18, each of the support connectors 66 and 68 and the shaft 18 will have been pivoted in a general direction 116 to a stored position, generally adjacent the support structure 12, as shown in dashed-lines in FIG. 2. In the storing position, each brace member 86 is interposed between one of the support connectors 66 and 68 and the support structure 12, and each brace member 86 and support connectors 66 and 68 are so disposed in one of the C-shaped flanges 94, as shown in dashed-lines in FIG. 2. The pins 96 are theneach inserted through each flange 94 to secure the brace members 86 and the support connectors 66 and 68 in a stored position.

To position the awning in the extended position as shown in FIGS. 1 and 2, the operator will initially remove each pin 96 from each C-shaped flange 94 and position the motor control 48 in the reverse position establishing continuity between the motor 40 and the motor power source 44 positioning the motor 40 in a second driven position. In the second driven position of the motor 40, torque is applied at the drive shaft 42 in a direction causing the motor 40 and the shaft 18 connected thereto to be rotated in a releasing direction 32 via the interconnections between the motor 40 and the shaft 18 and between the drive shaft 42 and the support connector 66.

As the awning 14 is releasingly unrolled from the shaft l8, each support connector 66 and 68 and the shaft 18 connected thereto will be pivoted in a general direction 118, to a position wherein the awning 14 is completely unrolled from the shaft 18 in the fully extended position. As previously noted, the motor controls 48 may interrupt continuity between the motor 40 and the power source 44 at any desired position of the awning 14 between the stored position and the extended position, the natural gravitational forces tend ing to pull the support connectors 66 and 68 and the shaft 18 in a general direction 118 maintaining the awning 14 taut.

When the awning 14 has been unrolled to a predetermined, selected position, the operator will then telescopingly extend each base member 76 in a general direction 80, to a position wherein the awning 14 is extended in a generally horizontal plane 'above the ground, as shown in FIGS. 1 and 2. Each of the screw members 82 are then threaded through one of the openings 83 in the base members 76 and positioned to securingly engage one of the rod members securing each of the rod members 70 in an assembled position with respect to one of the base members 76.

Each of the brace members 86 is then pivoted in a general direction to a position wherein each member 92 engages a portion of one of the base members 76, thereby preventing the pivotal movement of the support connectors 66 and 68 and the shaft 18 in a general direction 116 and securing the support assembly 16 in an assembled position.

lt will be apparent from the foregoing to those skilled in the art, that the awning control apparatus 10, described above, is constructed to uniformly roll and unroll the awning 14 in a more efficient manner. The various components and assemblies of the awning control apparatus 10 are constructed to cooperate in such a manner that, as the awning 14 is moved to a rolled and an unrolled position, each component and assembly is constructed and positioned to be quickly, conveniently and efficiently secured in a stored or extended position 10 relative to the support structure 12. lt should also be noted that, since the motor 40 is enclosed via the shaft 18 and the cap 54, the motor 40 is substantially protected from the elements during the operation of the awning control apparatus 10.
