D e s c r i p t i o n Outside Rear-View Mirror for a Vehicle The invention refers to an outside rear-view mirror for a vehicle which comprises a pedestal and a mirror housing mounted to the pedestal by means of a joint so as to be rockable relative to the pedestal upon impact from the front or from the rear.
German publication no. 34 29 713 discloses an outside rear-view mirror which includes a mirror housing and a pedestal fastened to a mounting plate. The mounting plate is adapted to be mounted to a car body. A joint for rockably holding the mirror housing on the pedes-tal includes a rivet which extends through aligned openings in the pedestal and in the lower portion of the mirror housing adjacent to the pedestal. Within the mirror housing a mirror is pivotably moun-ted which is coupled to an adjustment device which may be operated mechanically or electrically by manipulating a handle or switches provided in the interior of the car. Bowden cables or electric lines of the adjustment device extend from the interior of the mirror housing through the rivet of the joint and the pedestal to the handle or the switches within the car.
Means are provided at the joint, which ensure that the mirror housing assumes and maintains a normal position with respect to the pedestal and which allow rocking of the mirror housing towards the car body about the joint upon impact from the front or from the rear on the mirror housing. Such means include a spring member housed in aligned recesses and abutting radially on reference surfaces which are formed in a support portion of the pedestal surrounding the rivet and in an opposing support portion of the mirror housing.
A particular drawback is encountered when assembling this type of joint. Special tools are required for beading both ends of the rivet in order that the mirror housing is safely yet rockably clamped to .. ~
13()68~;
the pedestal. To this end a circumferential spring is utilized which is interposed between the support portion of the pedestal and the beaded rim of the rivet in the pedestal. When both ends of the rivet are beaded too extensively the support portions of the ~irror housing and the pedestal are pressed against each other to such an extent that the mirror housing is allowed to rock only upon forceful impacts, which reduces the overall safety feature of the outside rear-view mirror and includes the risk of damage caused by heavy impacts on the mirror housing. On the other hand, when both ends of the rivet are beaded only slightly, the seat of the mirror housing on the pedestal will allow vibrations of the mirror housing when the car is driven fast.
It is therefore an object of the invention to devise an improved outside rear-view mirror which does not show the drawback and incon-venience explained above. Specifically, the joint by which the mirror housing is mounted to the pedestal of the outside rear-view mirror is to be assembled more easily and is to meet still the requirements for a proper seat of the mirror housing on the pedes-tal. According to a yet more specific object of the invention, only a few separate parts should be necessary for obtaining a steady normal position of the mirror housing and for avoiding damage caused by the rocking mirror housing.
The outside rear-view mirror according to the invention comprises a pedestal having a mounting plate adapted to be fastened to a car body. A mirror housing including a light-reflecting mirror is moun-ted to the pedestal so as to be held in a normal position during all driving conditions and to be rockable about the joint upon impact from the front or from the rear. The joint is formed by a hollow bolt which extends through aligned bores in a first support portion of the mirror housing and a second support portion of the pedestal and the radially extending head of which is engaged by a spring pressing against the inner side of one of the said support portions.
The end of the hollow bolt is formed with at least one radial nose 13()~
and the contours of both bores are formed with at least one pair of aligned axial grooves so as to allow insertion of the hollow bolt through the aligned bores. After turning the inserted hollow bolt, its radial nose engages the other of said second support portions thereby completing the joint.
According to the invention the clamping force of the joint is deter-mined only by the force the spring is developping. No special tools or sensitive manipulating is required when assembling the joint.
Moreover, only two members are required for mounting the mirror housing to the pedestal, i.e~ the hollow bolt and the spring.
According to a preferred improvement of the invention, the second support is formed with at least one axially protruding projection adjacent to the end of the associated groove, which prevents an inadvertent return of the nose of the assembled bolt into the groove to the effect that the established joint cannot loosen when the mirror housing rocks. Preferably, an embodiment of the invention provides for a pair of such projections for catching the nose of the hollow bolt in a defined assembled position. According to a more specific embodiment of the invention, the end of the bolt opposite to the head thereof has three circumferentially equally spaced noses and the aligned openings are formed with three circumferentially equally spaced grooves, and the second support portion is formed with three pairs of projections, each pair for catching one of the noses of the assembled bolt.
According to a further improvement of the invention, the opposing abutment surfaces of the first support portion and the second support portion are formed with a radially extending rib cooperating with at least one correspondingly formed radially extending groove.
The rib and the groove are positioned such that the mirror housing assumes its normal position relative to the pedestal when the rib is caught within the groove. Additional radially extending grooves may ~306886 be provided at one of the abutment surfaces for defining end posi-tions of the rocking mirror housing towards the car body thereby preventing an undesired crash of the mirror housing to the car body.
The invention is explained in detail below with reference to the embodiment illustrated in the accompanying drawings, in which:
ig. l is a side view, partially in section, of an outside rear-view mirror of common type;
ig. 2 is an axial section through a joint according to the invention for mounting a mirror housing to a pedestal of an outside rear-view mirror according to Fig. 1, the section taken aong line A-A in Fig. 3;
ig. 3 a top view in direction X marked in Fig. l onto the support portion in the pedstal;
Fig. 4 a axial section through the hollow bolt of Fig. 2, and ig. S a top view on the hollow bolt according to Fig. 4.
Fig. 1 illustrates the overall structure of a known outside rear-view mirror as disclosed in German publication no. 34 29 713. A
mounting plate 50 is adapted to the form of the car body to which the outside rear-view mirror is intended to be mounted. A pedestal 52 is fastened to the mounting plate 50 and has an upper firm support portion 56 through which a first hole is bored. A mirror housing Sl of generally rectangular form bears a mirror 53 and has a second support portion 59 formed at its lower section adjacent to the pedestal. The second support portion 59 has a second bore of the same diameter as the first bore so that a rivet may extend through both aligned openings for clamping the mirror housing 51 to pedestal 130~88t~
52. A lower abutment surface 58 of the second support portion 59 abuts against the first abutment surface 57 of pedestal 52 when the mirror housing Sl is clamped to pedestal 52. A spring 56 is inter-posed between the first support portion 58 and one beaded end of the rivet.
An adjustment device not shown may extend through the rivet for coupling a handle or switches within the interior of the car to the mirror so that the position of the mirror may be adjusted to the personal requirements of the car driver.
The invention provides an improved joint which may be assembled more easily than the joint of the known outside rear-view mirror. Thus Fig. 2 shows in a section a mirror housing 1 of plastic material similar to mirror housing 51, which is provided at its lower end close to pedestal 2 with a breaking-through 4 surrounding a support part 3. Support part 3 is mounted to the lower end of a mounting plate 5, for instance by soldering, onto which the mirror housing 1 is screwed at points not shown. Support part 3 is mainly of cylind-rical shape and has at its outer contour a radially inwardly exten-ding step 6 to which mounting plate 5 is attached. The upper side of support part 3 extending into the interior of mirror housing 1 is of flat shape and has a support surface 7 for a spiral spring 8.
Support part 3 is provided with a centric boring 10 in which the hollow bolt 20 still to be described is seated. From the lower sur-face 9 a collar 11 protrudes in lower direction abutting on a support portion 30. Radially within collar 11 there is provided an annular recess 12 in support part 3, which is limited by an apron 13 towards boring lO. In lower direction apron 13 does not protrude over the lower surface ~.
Support portion 30 is shaped at a flat upper side 31 of pedestal 2 and has a through opening 32 which is in alignment with boring 10.
Radially outside of opening 32 a ring-shaped wall 33 raises from the upper side 31, penetrating into recess 12. Collar 11 abuts on that section of upper side 31 which is radially outside of the annular-shaped wall 33.
The hollow bolt 20 is mainly of cylindrical contour and has an axial bore-through 22. It consists of a broadened head 24 and followed by a shaft 26, the outer diameter of which equals the inner diameter of the mainly cylindrical boring 10 as well the inner diameter of the through opening 32. At the end of shaft 26 opposite to head 24 there are protruding in the embodiment shown three massive noses 27, 28, 29 in equally spaced relationship on the circumference of shaft 26, which are provided with a bevelling towards face 25 of shaft 26 facilitating the insertion of the hollow bolt 20 into the boring. At their end opposite to face 25 the noses 27, 28, 29, each adjoin the outer surface of shaft 26 by a radially inwardly extending shoulder 21. At the point where shaft 26 adjoins head 24, a radially protru-ding annular shoulder 19 is formed, over which the upper portion of head 24 extends outwardly. In the upper side 18 of head 24 opposite to face 25 there are cut radial slots 14, 15, 16, 17 permitting engagement of a screwdriver or a similar tool.
Three circumferentially equally spaced, axially directed grooves are cut into the inner surface of the boring, which make it possible that the hollow bolt with noses 27, 28, 29 may be inserted as e.g.
illustrated from the supporting surface 7 of the first support part 3 into boring 10 and through opening 32. From these grooves only grove 40 is shown in Fig. 2. The cross-section of each of the grooves 40 is only slightly greater than the cross-section of each of noses 27, 28, 29. Likewise, in the inner surface of through opening 32 there are cut three circumferentially equally space, axially extending grooves 41, 42, 43, which are in pairs in axial alignment with the grooves of boring 10, as can be seen in Fig. 2 at the example of the grooves 40, 41 lying axially above each other.
13~ 36 From the inner rim of through opening 32 there protrude axially small elevations on both sides of each of grooves 41, 42, 43. In Fig. 3 the elevations formed on boths sides of groove 41 are desig-nated with 34 and 35, in Fig. 2 elevation 34 may be seen. Between two adjacent elevations, e.g. between elevations 36 and 37, which are formed between two adjacent grooves, e.g. grooves 42 and 43, the rim of through opening 32 remains flat.
When the joint is assembled, spiral spring 8 is slid over shaft 26 until it abuts against the lower side of head 24. The hollow bolt is then inserted in boring 10 and pushed through through opening 32 against the force of spring 8, until noses 27, 28, 29 come out of the lower side of counter support 30. During this pushing each of the noses penetrates through a pair of grooves being in axial align-ment. Hollow bolt 20 is then turned by means of a tool about its axis until the noses 27, 28, 29 are captured in the intermediate spaces of respectively two adjacent elevations, for instance, as illustrated, nose 28 between elevations 36 and 37. To this end hollow bolt 20 should be rotated by approx. 60. Nose 28 may, of course, also be captured between two different adjacent elevations.
The joint is then completely assembled. When mirror housing 1 is pivoted relative to pedestal 2, the lower side of collar 11 abuts on the upper side 2.
In order to define the position of use desired for mirror housing 1 relative to pedestal 2, i.e. its normal position, three radially extending ribs 45, 46, 47 are formed around the circumference of through opening 32 from the upper side 31 radially outside of ring-shaped wall 33. Likewise, in the inner side 9, beginning from the inner wall of boring 3, there are located three radially extending recesses on the circumference of boring 10, the contours of which correspond to the contours of ribs 45, 46, 47. In Fig. 2 a recess 48 is shown. Although three ribs 45, 46, 47 are shown, a single rib will also suffice which, when cooperating with one of the recesses 13C~
48, defines a specific angular position of the mirror housing rela-tive to the pedestal. One of these angular posititions is the posi-tion of use of the mirror housing (normal position) when the pedes-tal is attached to the car body of a motor vehicle. Further angular positions defined by the engagement of the rib into one of the other recesses are the terminal rocking position of the mirror housing to the car body in forward driving direction and a terminal rocking position of the mirror housing to the car body in backward driving direction. When the recesses 48 are in proper spaced relationship on the circumference of boring 10, e.g. in a relationship of 120 respectively, the three mentioned angular positions of mirror hou-sing 1 relative to pedestal 2 are defined. The housing is kept in each of the angular pivoting positions due to the snapping of the rib in one of the recesses 48 and the force of spring 8. A manual pressing of mirror housing 1 out of one of the angular positions against the force of spring 8 is facilitated when the recesses and flanks of the ribs are bevelled. During the rocking movements of mirror housing 1 relative to pedestal 2, hollow bolt 20 may not rotate about its axis because noses 27, 28, 29 remain captured between elevations 34 ... 37.
It is within the scope of the invention to insert the hollow bolt 20 from below into the openings 32 and 10. 0f course, the radially extended head 24 will then be positioned within the hollow space of pedestal 2, the spring 8 being interposed between the underside of support 30 and the head 24 of bolt 20. It is to be understood that the form of the pedestal in such case should be selected more in line to that one shown in Fig. 1. Moreover, the bottom wall of the pedestal should then have an additional opening opposite to opening 32 for facilitating the insertion of bolt 20. Such additional opening may be closed by a suitable plastic cap.
D e s c r i p t i o n Outside Rear-View Mirror for a Vehicle The invention refers to an outside rear-view mirror for a vehicle which comprises a pedestal and a mirror housing mounted to the pedestal by means of a joint so as to be rockable relative to the pedestal upon impact from the front or from the rear.

Bowden cables or electric lines of the adjustment device extend from the interior of the mirror housing through the rivet of the joint and the pedestal to the handle or the switches within the car.
Means are provided at the joint, which ensure that the mirror housing assumes and maintains a normal position with respect to the pedestal and which allow rocking of the mirror housing towards the car body about the joint upon impact from the front or from the rear on the mirror housing. Such means include a spring member housed in aligned recesses and abutting radially on reference surfaces which are formed in a support portion of the pedestal surrounding the rivet and in an opposing support portion of the mirror housing.

The joint is formed by a hollow bolt which extends through aligned bores in a first support portion of the mirror housing and a second support portion of the pedestal and the radially extending head of which is engaged by a spring pressing against the inner side of one of the said support portions.
The end of the hollow bolt is formed with at least one radial nose 13()~

The rib and the groove are positioned such that the mirror housing assumes its normal position relative to the pedestal when the rib is caught within the groove. Additional radially extending grooves may ~306886 be provided at one of the abutment surfaces for defining end posi-tions of the rocking mirror housing towards the car body thereby preventing an undesired crash of the mirror housing to the car body.
The invention is explained in detail below with reference to the embodiment illustrated in the accompanying drawings, in which:
ig. l is a side view, partially in section, of an outside rear-view mirror of common type;
ig. 2 is an axial section through a joint according to the invention for mounting a mirror housing to a pedestal of an outside rear-view mirror according to Fig. 1, the section taken aong line A-A in Fig. 3;
ig. 3 a top view in direction X marked in Fig. l onto the support portion in the pedstal;
Fig. 4 a axial section through the hollow bolt of Fig. 2, and ig. S a top view on the hollow bolt according to Fig. 4.
Fig. 1 illustrates the overall structure of a known outside rear-view mirror as disclosed in German publication no. 34 29 713. A
mounting plate 50 is adapted to the form of the car body to which the outside rear-view mirror is intended to be mounted. A pedestal 52 is fastened to the mounting plate 50 and has an upper firm support portion 56 through which a first hole is bored. A mirror housing Sl of generally rectangular form bears a mirror 53 and has a second support portion 59 formed at its lower section adjacent to the pedestal. The second support portion 59 has a second bore of the same diameter as the first bore so that a rivet may extend through both aligned openings for clamping the mirror housing 51 to pedestal 130~88t~
52. A lower abutment surface 58 of the second support portion 59 abuts against the first abutment surface 57 of pedestal 52 when the mirror housing Sl is clamped to pedestal 52. A spring 56 is inter-posed between the first support portion 58 and one beaded end of the rivet.
An adjustment device not shown may extend through the rivet for coupling a handle or switches within the interior of the car to the mirror so that the position of the mirror may be adjusted to the personal requirements of the car driver.
The invention provides an improved joint which may be assembled more easily than the joint of the known outside rear-view mirror. Thus Fig. 2 shows in a section a mirror housing 1 of plastic material similar to mirror housing 51, which is provided at its lower end close to pedestal 2 with a breaking-through 4 surrounding a support part 3. Support part 3 is mounted to the lower end of a mounting plate 5, for instance by soldering, onto which the mirror housing 1 is screwed at points not shown. Support part 3 is mainly of cylind-rical shape and has at its outer contour a radially inwardly exten-ding step 6 to which mounting plate 5 is attached. The upper side of support part 3 extending into the interior of mirror housing 1 is of flat shape and has a support surface 7 for a spiral spring 8.
Support part 3 is provided with a centric boring 10 in which the hollow bolt 20 still to be described is seated. From the lower sur-face 9 a collar 11 protrudes in lower direction abutting on a support portion 30. Radially within collar 11 there is provided an annular recess 12 in support part 3, which is limited by an apron 13 towards boring lO. In lower direction apron 13 does not protrude over the lower surface ~.
Support portion 30 is shaped at a flat upper side 31 of pedestal 2 and has a through opening 32 which is in alignment with boring 10.
Radially outside of opening 32 a ring-shaped wall 33 raises from the upper side 31, penetrating into recess 12. Collar 11 abuts on that section of upper side 31 which is radially outside of the annular-shaped wall 33.
The hollow bolt 20 is mainly of cylindrical contour and has an axial bore-through 22. It consists of a broadened head 24 and followed by a shaft 26, the outer diameter of which equals the inner diameter of the mainly cylindrical boring 10 as well the inner diameter of the through opening 32. At the end of shaft 26 opposite to head 24 there are protruding in the embodiment shown three massive noses 27, 28, 29 in equally spaced relationship on the circumference of shaft 26, which are provided with a bevelling towards face 25 of shaft 26 facilitating the insertion of the hollow bolt 20 into the boring. At their end opposite to face 25 the noses 27, 28, 29, each adjoin the outer surface of shaft 26 by a radially inwardly extending shoulder 21. At the point where shaft 26 adjoins head 24, a radially protru-ding annular shoulder 19 is formed, over which the upper portion of head 24 extends outwardly. In the upper side 18 of head 24 opposite to face 25 there are cut radial slots 14, 15, 16, 17 permitting engagement of a screwdriver or a similar tool.
Three circumferentially equally spaced, axially directed grooves are cut into the inner surface of the boring, which make it possible that the hollow bolt with noses 27, 28, 29 may be inserted as e.g.
illustrated from the supporting surface 7 of the first support part 3 into boring 10 and through opening 32. From these grooves only grove 40 is shown in Fig. 2. The cross-section of each of the grooves 40 is only slightly greater than the cross-section of each of noses 27, 28, 29. Likewise, in the inner surface of through opening 32 there are cut three circumferentially equally space, axially extending grooves 41, 42, 43, which are in pairs in axial alignment with the grooves of boring 10, as can be seen in Fig. 2 at the example of the grooves 40, 41 lying axially above each other.
13~ 36 From the inner rim of through opening 32 there protrude axially small elevations on both sides of each of grooves 41, 42, 43. In Fig. 3 the elevations formed on boths sides of groove 41 are desig-nated with 34 and 35, in Fig. 2 elevation 34 may be seen. Between two adjacent elevations, e.g. between elevations 36 and 37, which are formed between two adjacent grooves, e.g. grooves 42 and 43, the rim of through opening 32 remains flat.
When the joint is assembled, spiral spring 8 is slid over shaft 26 until it abuts against the lower side of head 24. The hollow bolt is then inserted in boring 10 and pushed through through opening 32 against the force of spring 8, until noses 27, 28, 29 come out of the lower side of counter support 30. During this pushing each of the noses penetrates through a pair of grooves being in axial align-ment. Hollow bolt 20 is then turned by means of a tool about its axis until the noses 27, 28, 29 are captured in the intermediate spaces of respectively two adjacent elevations, for instance, as illustrated, nose 28 between elevations 36 and 37. To this end hollow bolt 20 should be rotated by approx. 60. Nose 28 may, of course, also be captured between two different adjacent elevations.
The joint is then completely assembled. When mirror housing 1 is pivoted relative to pedestal 2, the lower side of collar 11 abuts on the upper side 2.
In order to define the position of use desired for mirror housing 1 relative to pedestal 2, i.e. its normal position, three radially extending ribs 45, 46, 47 are formed around the circumference of through opening 32 from the upper side 31 radially outside of ring-shaped wall 33. Likewise, in the inner side 9, beginning from the inner wall of boring 3, there are located three radially extending recesses on the circumference of boring 10, the contours of which correspond to the contours of ribs 45, 46, 47. In Fig. 2 a recess 48 is shown. Although three ribs 45, 46, 47 are shown, a single rib will also suffice which, when cooperating with one of the recesses 13C~
48, defines a specific angular position of the mirror housing rela-tive to the pedestal. One of these angular posititions is the posi-tion of use of the mirror housing (normal position) when the pedes-tal is attached to the car body of a motor vehicle. Further angular positions defined by the engagement of the rib into one of the other recesses are the terminal rocking position of the mirror housing to the car body in forward driving direction and a terminal rocking position of the mirror housing to the car body in backward driving direction. When the recesses 48 are in proper spaced relationship on the circumference of boring 10, e.g. in a relationship of 120 respectively, the three mentioned angular positions of mirror hou-sing 1 relative to pedestal 2 are defined. The housing is kept in each of the angular pivoting positions due to the snapping of the rib in one of the recesses 48 and the force of spring 8. A manual pressing of mirror housing 1 out of one of the angular positions against the force of spring 8 is facilitated when the recesses and flanks of the ribs are bevelled. During the rocking movements of mirror housing 1 relative to pedestal 2, hollow bolt 20 may not rotate about its axis because noses 27, 28, 29 remain captured between elevations 34 ... 37.
It is within the scope of the invention to insert the hollow bolt 20 from below into the openings 32 and 10. 0f course, the radially extended head 24 will then be positioned within the hollow space of pedestal 2, the spring 8 being interposed between the underside of support 30 and the head 24 of bolt 20. It is to be understood that the form of the pedestal in such case should be selected more in line to that one shown in Fig. 1. Moreover, the bottom wall of the pedestal should then have an additional opening opposite to opening 32 for facilitating the insertion of bolt 20. Such additional opening may be closed by a suitable plastic cap.
