Description
CA 022444~9 1998-07-31 ~olding arm for an external motor vehicle mirroi- with integrated swivel articulation The present invention relates to a holding arm tor an externai motor vehlcle mirror witn an integrated swivel articulation capable of snapping in in at least one position.
A mirror arm mec~l~nicm of this type is known from EP O 641 686 A2. With the swivel articulation shown there, the different snap-in elements which are subjected to the force of a helicoidal screw spring in the direction of engagement of the snap-in mechanism. The embodiments shown therein have in cornmon tha~ different axially and radially acting wedge surfaces intermesh on rings or ring segment elements seated within each other in a relatively complex manner. To this extent the known swivel articulation is of complicated design and its assembly is expensive. Furtherrnore with the known swivel articulation, especially with an embodiment in which different separate ring segment are used to constitute snap-in wedge surfaces, the snap-element can jam with each other. This would block the swivel articulation which could no longer carry out its safety function, i.e. swiveling back when the e~cternal mirror supported by the holding arm impacts an obstacle. Due to blocking or at least due to the sluggishness caused by the interaction of the various internal parts of the swivelling articulation the manual swiveling of the mirror, e.g. to pass narrow passages, is rendered more difficult.
With respect to the state of the art it should be pointed out as a general background that with such holding arms with snap-in swivel articulation, articulation designs are often used where the CA 022444~9 1998-07-31 arrn segments em~n~ting from the swiveling articulation are o~set relative to each other during snapping in and out of the swiveling articulation. This offset has been compensated for in the past by the elasticiiy of holding arms of considerable len~th Modern, up-to-date mirror designs o~Len have only very short holding arms however, which extend directly in horizontal direction from the car body to the mirror housing. Especially with these designs, the clearance for length compensation is very limited. One solution of this problem is already provided by the above-mentioned EP 0 641 686 A2, however with the above-mentioned disadvantages. ~ ~
On the basis of the above, the invention has as its object to present a holding arm with snap-in swiveling articulation whereby the two arm segments can be adjusted as before relative to each other without shifting and while the swiveling articulation snaps in and out, but whereby the swivel or snap-in mechanism is simpler and thereby easier to assemble and more compact This object is attained through the characteristics ind,cated in claim 1. According to these the holding arm according to the invention is basically an arm that is continuous at least in the area of the swiveling articulation, whereby the swiveling axis of the swiveling articulation formed between the two arm segments is at a right angle to the longitudinal direction of the arm segments. The counter-snap-in element under spring pressure in the direction of engagement with CA 022444~9 1998-07-31 the snap-in element is suspended according to the invention at the *ee end of a bearing brace made like a leaf spring which is attached by its fiYed end to this appertaining arrn segment.
The leaf-spring bearing brace ensures on the one hand that the counter-snap-in element is under spring pressure, and on the other hand provides the excursion path of the counter-snap-in element when an arm segment is swiveled relative to the other arm segment. Finally the bearing brace also ensures non-rotatable holding of the counter-snap-in element, so that corresponding wedge and groove connections of the counter-snap-in element with its appertaining arm segment, as is required in the s~ate of the art, may be omitted Preferred embodiments as well as other characteristics, details and advantages of the invention are contained in the sub-claims or in the description below, in which examples of embodiments of the object of the invention are explained through attached drawings.
Fig. I shows a vertical longitudinal section through the swiveling articulatlon of a holding arm in a first embodiment, Fig. 2 shows a top view of a swiveling articulation in a second embodiment and Fig. 3 shows a view of the swiveling articulation along a line 111-111 according to Fig. 2 CA 022444~9 1998-07-31 In the embodiment shown in Fig. 1 the swiveling articulation desi"nated by refere.~ce l in its entirety connects the two arrn segments 2, 3 of a holding arm of an external truck mirror The arm segrnent 2 shown in Fig I on the left side consists here of a bearing pressure-cast ~,art 4 located below, which leads to the truck body. The part 4 is covered by a screen 5 which leaves the end 6 free for the formation of the swiveling articulation.
The arrn segment 3 which extends to the right on Fig. I is provided on top with a bearing pressure-cast part 7 which supports the external mirror on its end which is not shown On the underside of the pressure-cast part 7 a screen 8 is also placed, leaving the end 9 of the arm segment 3 free.
On this end 9 a kind of axle stump I l is formed in one piece, into which the end of a threaded bolt 13 in form of a square block 12 is incorporated by casting and is thus non-rotatably connected to it. The 1 1 is coaxial with the 13 which defines the swivel axis 14 of the swiveling articulation 1.
For interaction with the threaded bolt 13~ the low-lying end 5 of the arm segment 2 which overlaps the higher-lying end 9 of the arrn segment 3 is provided with a sleeve extension 10 made in one piece with it, the central bore 15 of which has a diameter such that a spacer sleeve 16 and on top of it a gliding sleeve 17 can be inserted between the arm segment l 3 and bore 15. Pointing down, a mounting bore 18 with wider diameter in which the threaded bolt 13 end follows the bore 15. By screwing on a mlt 19 with an intercalated spring washer 20, the two . . .
CA 022444~9 1998-07-31 arm segments 2, 3 can be c(>nnected to each other without ~learance in the direction ot'the swivel axis 14 but are able to swivel around the latter The faces of the a~le stump I I and of the sleeve extension 10 then come into contact with each other, but are not screwed together so tightly, due to the spacer sleeve 16 and the spring shim 20, that swiveling becomes impossible.
The swiveling articulation I can be snapped in, at least in the extended stalting position shown in Fig. I, by means of a snap-in device designated by reference 21 in its entire~y. The snap-in device 21 is provided with a snap-in ring 22 assigned to the arm segment 2 as a first snap-in element, said snap-in ring 22 being held non-rotatably in an annular ~;roo~ e 2 3 open on top in the end 6 of the arm segment 2. The snap-in ring has several snap-in grooves 24 distributed over the circumference of its upper face, said grooves having a trapezoici prohle in circumferential as well as in radial direction (as can be seen in Fig. 1.
A counter-snap-in ring 25 which is associated with the upper arm segment 3 interacts with the snap--in ring 2. The counter-snap-in ring 25 is suspended on a bearing brace 26 which runs parallel to the longitudinal direction of the upper arm segment 3 and at a right angle to the swivel axis 14 to a bearing block 27 located before then end 9 of the arm segment 3. The bearing brace 26 is in form of a punched-out leaf spring sheet-metal part the shaft of which is attached by its fixed end 28 on the bearing block 27 by means of an attachment screw 29 The free end of the bearing brace 26 is made in one piece with the shaft '8 and made in form of an anchoring ring 30, the contour of which follows essentially the contour of the counter-snap-in ring 25 as seen from above. Additional attachment scre-vs 31 attach the collnter-snap-l[l rln, 'S to the anchoring ring 30 of the bearing brace 26.
Fig. I clearly shows that the counter-snap-in ring 25 has snap-in noses 32 on its face pointing down which have complementary contours to the snap-in grooves 24. The bearing brace 26 in form of a leaf spring ensures that the snap-in noses 32 enter the snap-in groo~res 24, and this is further assisted by a Belleville spring package 33 threaded on the axle stump 11. The latter is located between the back of the anchoring ring 30 away frorn the counter-snap--in ring 25 and a counter bearing 34 at the end 9 of the arm segment 3 As can be further seen in Fig 1, the swivel articulation I is e ompletely inte,,rated into the cross-sectional contour of the arm segments 2, 3 since it protrudes neither upward nor downward, nor on the sides beyond the outside of the arm segments 2, 3.
Concerning the function of the swivel articulation I with axial snap-in, it should be pointed oul briefly that as a torque is exerted on the arrn segment 3, this is transmitted via the bearing brace 26 to the counter-snap-in ring 25 causing it to be lifted by the bearing brace 26 and the Belleville spring package 33 up and with its snap-in noses 32 out of the snap-in grooves 24 of the snap-in ring 22 againse the force of the spring, and the arm segment 3 becomes capable of swiveling relative to the arm segment 2 At the same time there results no shift of the arm segment 2 relative to the arm segment 3 in direction of the swivel axis 14 The object of the invention thus strives for a clearance-free, flat and veri compact swivel snap-in in a holdin~ arnl tor e~;ternal motor vehicle mirrors. By providing a plurality of equidistant snap-in groo~es 24 and snap-in noses 32 on the snap-in ring 22 or on the counter-snap-in ring '5, a step by slep sllapping in of the swivel articulation 1 is filrtherrnore possible.
In the embodiment shown in Figs. 2 and 3 a snap-in device 21 is provided, with which the snap-in meshing is radial. The difference in this respect ~om the embodiment shown in Fig. I sh.~l be explained in further detail below. To avoid repetition it is however pointed out that the swivel articulation 1' ofthe embodiment according to Figs ~ and 3 i.s installed in the same manner between two arm segments 2,, of a mirror holding arm For this reason Inat~hing component are given identical ret'erence numbers in both embodiments and require no further explanation.
The swivel bearing in the embodiment according to ~igs 2 and 3 is effected by an axle stump 11' which completely traverses a bearing bore 15' in the end a snap ring 36 is placed with intercalation of a spring washer 3 5, so that the two arm segments 2,, are connected to each other in the area of the swivel articulation practically without clearance and in an articulated manner. In order to reduce friction between the two bearing partners, a gliding disk ring 37 threaded on the axle stump 11 is provided between the underside and the upper side of the arm segments 2, 3.
The snap-in element on the arm segment 2 is a row of snap-in teeth 38 which extends over the circumferential surface of a bearing element forming the bearing bore 15' at the end 6 of the arm CA 022444~9 1998-07-31 segment 2. This row of snap-in teeth has trapezoidal snap-in :eeth ~0 In profile which leave snap-in recesses 41 between them.
The counter-snap-in element is a counter-snap-in block 4 which is provided with face teeth 4 3 which complement the row of snap-in teeth 38 and has two snap-in teeth 44 with a snap-in recess 45 between them. On the back 46 away from the face teeth 43 a leaf spring bearing brace 26' is again attached by its free end, its fixed end 28' being attached to a projection 47 of the inner contour ofthe arrn segment 3 The attachment between bearing brace ~6' and counter-snap-in block 42 or proje~tion 47 can be effected as in Fig. I through screwing or rivetin~, suitable clamping etc. Finally it should be pointed out that in the embodiment according to Figs I or 2 and 3 both bearing braces 26, 26' can also constitute the counter-snap-in protlle itself at the same time Thus for example, the bearing brace 26' can be configured in continuation of its free end according to the contour of the counter-snap-:n block 4. ~ so that the latter would be an integral part of the bearing brace.
As Figs. 2 and 3 clearly show, the bearing brace 26' is in addition supported between its crimped free end 48 and a counter-bearing 34' in the arm segment 3 by a coiled pressure spring 49. The counter-snap-in block 42 with bearing brace 26' and coiled pressure spring 49 is then located in a compartment-like recess 50 in the arm segment 3 It should again be stated hriç~ly, concerning the functlon ot'the sn~p-in device 21'~ that e.g. the extended position of the two arm segments 2, 3 shown in Figs. 2 and; is suspended when torque is applied to the arm segment 3 in that this torque is transmitted via bearing brace 26' to the counter-snap-in block 42. The latter is corresponding lifted out vvith its f'ace teeth 43 from the row of snap-in teeth 38 against the force of the spring by the bearing brace 26' and the coiled compression spring 49. Consequently a swiveling movement until the face teeth 43 and the row of snap-in teeth 38 engage each other with one or more teeth offset. It can again be seen that the bearing brace 26' ensures a mobility of the counter-snap-in block J.~ which is independent of the arm segment 3, so~that with the excursion movement of the snap-in no change in the positions of the two arm segments 2, 3 relative to each other occurs Also in the second embodiment, the overall snap-in mechanism remains within the cross-sectional contour of the arm segments 2, 3 as can be clearly seen when viewing Figs. 2 and 3 together.
A mirror arm mec~l~nicm of this type is known from EP O 641 686 A2. With the swivel articulation shown there, the different snap-in elements which are subjected to the force of a helicoidal screw spring in the direction of engagement of the snap-in mechanism. The embodiments shown therein have in cornmon tha~ different axially and radially acting wedge surfaces intermesh on rings or ring segment elements seated within each other in a relatively complex manner. To this extent the known swivel articulation is of complicated design and its assembly is expensive. Furtherrnore with the known swivel articulation, especially with an embodiment in which different separate ring segment are used to constitute snap-in wedge surfaces, the snap-element can jam with each other. This would block the swivel articulation which could no longer carry out its safety function, i.e. swiveling back when the e~cternal mirror supported by the holding arm impacts an obstacle. Due to blocking or at least due to the sluggishness caused by the interaction of the various internal parts of the swivelling articulation the manual swiveling of the mirror, e.g. to pass narrow passages, is rendered more difficult.
With respect to the state of the art it should be pointed out as a general background that with such holding arms with snap-in swivel articulation, articulation designs are often used where the CA 022444~9 1998-07-31 arrn segments em~n~ting from the swiveling articulation are o~set relative to each other during snapping in and out of the swiveling articulation. This offset has been compensated for in the past by the elasticiiy of holding arms of considerable len~th Modern, up-to-date mirror designs o~Len have only very short holding arms however, which extend directly in horizontal direction from the car body to the mirror housing. Especially with these designs, the clearance for length compensation is very limited. One solution of this problem is already provided by the above-mentioned EP 0 641 686 A2, however with the above-mentioned disadvantages. ~ ~
On the basis of the above, the invention has as its object to present a holding arm with snap-in swiveling articulation whereby the two arm segments can be adjusted as before relative to each other without shifting and while the swiveling articulation snaps in and out, but whereby the swivel or snap-in mechanism is simpler and thereby easier to assemble and more compact This object is attained through the characteristics ind,cated in claim 1. According to these the holding arm according to the invention is basically an arm that is continuous at least in the area of the swiveling articulation, whereby the swiveling axis of the swiveling articulation formed between the two arm segments is at a right angle to the longitudinal direction of the arm segments. The counter-snap-in element under spring pressure in the direction of engagement with CA 022444~9 1998-07-31 the snap-in element is suspended according to the invention at the *ee end of a bearing brace made like a leaf spring which is attached by its fiYed end to this appertaining arrn segment.
The leaf-spring bearing brace ensures on the one hand that the counter-snap-in element is under spring pressure, and on the other hand provides the excursion path of the counter-snap-in element when an arm segment is swiveled relative to the other arm segment. Finally the bearing brace also ensures non-rotatable holding of the counter-snap-in element, so that corresponding wedge and groove connections of the counter-snap-in element with its appertaining arm segment, as is required in the s~ate of the art, may be omitted Preferred embodiments as well as other characteristics, details and advantages of the invention are contained in the sub-claims or in the description below, in which examples of embodiments of the object of the invention are explained through attached drawings.
Fig. I shows a vertical longitudinal section through the swiveling articulatlon of a holding arm in a first embodiment, Fig. 2 shows a top view of a swiveling articulation in a second embodiment and Fig. 3 shows a view of the swiveling articulation along a line 111-111 according to Fig. 2 CA 022444~9 1998-07-31 In the embodiment shown in Fig. 1 the swiveling articulation desi"nated by refere.~ce l in its entirety connects the two arrn segments 2, 3 of a holding arm of an external truck mirror The arm segrnent 2 shown in Fig I on the left side consists here of a bearing pressure-cast ~,art 4 located below, which leads to the truck body. The part 4 is covered by a screen 5 which leaves the end 6 free for the formation of the swiveling articulation.
The arrn segment 3 which extends to the right on Fig. I is provided on top with a bearing pressure-cast part 7 which supports the external mirror on its end which is not shown On the underside of the pressure-cast part 7 a screen 8 is also placed, leaving the end 9 of the arm segment 3 free.
On this end 9 a kind of axle stump I l is formed in one piece, into which the end of a threaded bolt 13 in form of a square block 12 is incorporated by casting and is thus non-rotatably connected to it. The 1 1 is coaxial with the 13 which defines the swivel axis 14 of the swiveling articulation 1.
For interaction with the threaded bolt 13~ the low-lying end 5 of the arm segment 2 which overlaps the higher-lying end 9 of the arrn segment 3 is provided with a sleeve extension 10 made in one piece with it, the central bore 15 of which has a diameter such that a spacer sleeve 16 and on top of it a gliding sleeve 17 can be inserted between the arm segment l 3 and bore 15. Pointing down, a mounting bore 18 with wider diameter in which the threaded bolt 13 end follows the bore 15. By screwing on a mlt 19 with an intercalated spring washer 20, the two . . .
CA 022444~9 1998-07-31 arm segments 2, 3 can be c(>nnected to each other without ~learance in the direction ot'the swivel axis 14 but are able to swivel around the latter The faces of the a~le stump I I and of the sleeve extension 10 then come into contact with each other, but are not screwed together so tightly, due to the spacer sleeve 16 and the spring shim 20, that swiveling becomes impossible.
The swiveling articulation I can be snapped in, at least in the extended stalting position shown in Fig. I, by means of a snap-in device designated by reference 21 in its entire~y. The snap-in device 21 is provided with a snap-in ring 22 assigned to the arm segment 2 as a first snap-in element, said snap-in ring 22 being held non-rotatably in an annular ~;roo~ e 2 3 open on top in the end 6 of the arm segment 2. The snap-in ring has several snap-in grooves 24 distributed over the circumference of its upper face, said grooves having a trapezoici prohle in circumferential as well as in radial direction (as can be seen in Fig. 1.
A counter-snap-in ring 25 which is associated with the upper arm segment 3 interacts with the snap--in ring 2. The counter-snap-in ring 25 is suspended on a bearing brace 26 which runs parallel to the longitudinal direction of the upper arm segment 3 and at a right angle to the swivel axis 14 to a bearing block 27 located before then end 9 of the arm segment 3. The bearing brace 26 is in form of a punched-out leaf spring sheet-metal part the shaft of which is attached by its fixed end 28 on the bearing block 27 by means of an attachment screw 29 The free end of the bearing brace 26 is made in one piece with the shaft '8 and made in form of an anchoring ring 30, the contour of which follows essentially the contour of the counter-snap-in ring 25 as seen from above. Additional attachment scre-vs 31 attach the collnter-snap-l[l rln, 'S to the anchoring ring 30 of the bearing brace 26.
Fig. I clearly shows that the counter-snap-in ring 25 has snap-in noses 32 on its face pointing down which have complementary contours to the snap-in grooves 24. The bearing brace 26 in form of a leaf spring ensures that the snap-in noses 32 enter the snap-in groo~res 24, and this is further assisted by a Belleville spring package 33 threaded on the axle stump 11. The latter is located between the back of the anchoring ring 30 away frorn the counter-snap--in ring 25 and a counter bearing 34 at the end 9 of the arm segment 3 As can be further seen in Fig 1, the swivel articulation I is e ompletely inte,,rated into the cross-sectional contour of the arm segments 2, 3 since it protrudes neither upward nor downward, nor on the sides beyond the outside of the arm segments 2, 3.
Concerning the function of the swivel articulation I with axial snap-in, it should be pointed oul briefly that as a torque is exerted on the arrn segment 3, this is transmitted via the bearing brace 26 to the counter-snap-in ring 25 causing it to be lifted by the bearing brace 26 and the Belleville spring package 33 up and with its snap-in noses 32 out of the snap-in grooves 24 of the snap-in ring 22 againse the force of the spring, and the arm segment 3 becomes capable of swiveling relative to the arm segment 2 At the same time there results no shift of the arm segment 2 relative to the arm segment 3 in direction of the swivel axis 14 The object of the invention thus strives for a clearance-free, flat and veri compact swivel snap-in in a holdin~ arnl tor e~;ternal motor vehicle mirrors. By providing a plurality of equidistant snap-in groo~es 24 and snap-in noses 32 on the snap-in ring 22 or on the counter-snap-in ring '5, a step by slep sllapping in of the swivel articulation 1 is filrtherrnore possible.
In the embodiment shown in Figs. 2 and 3 a snap-in device 21 is provided, with which the snap-in meshing is radial. The difference in this respect ~om the embodiment shown in Fig. I sh.~l be explained in further detail below. To avoid repetition it is however pointed out that the swivel articulation 1' ofthe embodiment according to Figs ~ and 3 i.s installed in the same manner between two arm segments 2,, of a mirror holding arm For this reason Inat~hing component are given identical ret'erence numbers in both embodiments and require no further explanation.
The swivel bearing in the embodiment according to ~igs 2 and 3 is effected by an axle stump 11' which completely traverses a bearing bore 15' in the end a snap ring 36 is placed with intercalation of a spring washer 3 5, so that the two arm segments 2,, are connected to each other in the area of the swivel articulation practically without clearance and in an articulated manner. In order to reduce friction between the two bearing partners, a gliding disk ring 37 threaded on the axle stump 11 is provided between the underside and the upper side of the arm segments 2, 3.
The snap-in element on the arm segment 2 is a row of snap-in teeth 38 which extends over the circumferential surface of a bearing element forming the bearing bore 15' at the end 6 of the arm CA 022444~9 1998-07-31 segment 2. This row of snap-in teeth has trapezoidal snap-in :eeth ~0 In profile which leave snap-in recesses 41 between them.
The counter-snap-in element is a counter-snap-in block 4 which is provided with face teeth 4 3 which complement the row of snap-in teeth 38 and has two snap-in teeth 44 with a snap-in recess 45 between them. On the back 46 away from the face teeth 43 a leaf spring bearing brace 26' is again attached by its free end, its fixed end 28' being attached to a projection 47 of the inner contour ofthe arrn segment 3 The attachment between bearing brace ~6' and counter-snap-in block 42 or proje~tion 47 can be effected as in Fig. I through screwing or rivetin~, suitable clamping etc. Finally it should be pointed out that in the embodiment according to Figs I or 2 and 3 both bearing braces 26, 26' can also constitute the counter-snap-in protlle itself at the same time Thus for example, the bearing brace 26' can be configured in continuation of its free end according to the contour of the counter-snap-:n block 4. ~ so that the latter would be an integral part of the bearing brace.
As Figs. 2 and 3 clearly show, the bearing brace 26' is in addition supported between its crimped free end 48 and a counter-bearing 34' in the arm segment 3 by a coiled pressure spring 49. The counter-snap-in block 42 with bearing brace 26' and coiled pressure spring 49 is then located in a compartment-like recess 50 in the arm segment 3 It should again be stated hriç~ly, concerning the functlon ot'the sn~p-in device 21'~ that e.g. the extended position of the two arm segments 2, 3 shown in Figs. 2 and; is suspended when torque is applied to the arm segment 3 in that this torque is transmitted via bearing brace 26' to the counter-snap-in block 42. The latter is corresponding lifted out vvith its f'ace teeth 43 from the row of snap-in teeth 38 against the force of the spring by the bearing brace 26' and the coiled compression spring 49. Consequently a swiveling movement until the face teeth 43 and the row of snap-in teeth 38 engage each other with one or more teeth offset. It can again be seen that the bearing brace 26' ensures a mobility of the counter-snap-in block J.~ which is independent of the arm segment 3, so~that with the excursion movement of the snap-in no change in the positions of the two arm segments 2, 3 relative to each other occurs Also in the second embodiment, the overall snap-in mechanism remains within the cross-sectional contour of the arm segments 2, 3 as can be clearly seen when viewing Figs. 2 and 3 together.
