Abstract
Title: Adjustable motor car mirror, and safety housing for mounting such a mirror.
Abstract of the disclosure:
An apparatus for adjusting a mirror or a similar flat planar element about two mutually perpendicular axes. The apparatus has a housing enclosing a reversible motor an electro-magnetically operated clutch and two planetary transmission assemblies, one for each direction of movement. The clutch selectively couples the motor to one or the other of the two pinion sun wheels of the planetary transmission systems. The drive shaft of each planetary transmission assembly is provided with a dog, which engages a corresponding mirror adjustment unit. A mirror mounting plate is provided with recesses into which correspondingly shaped parts of the mirror adjustment units are introduced by snap forcing.
To suppress vibration of the mirror, the units are preferably arranged to act upon a tilting adjusting ring which in any position is in sealing contact with a raised edge of the bottom member of the housing. A safety housing for mounting the apparatus comprises a protective cap housing two substantially parallel partitions spaced apart so as to be capable of receiving the top part of a mounting column between them.
Clamping means force the partitions against the surface of the column. The cap will thus withstand light impact forces, but turn relative to the column when struck by a bicycle or other vehicle in traffic.

~ . . . .
~ objection i.s that the work of attaching the mirror to the , : ..

The aim of the invention is to provide a device for :-:` adjusting a motor car mirror about two mutually perpendicular : axes, such. device not being subject to the above-mentioned -objections, while being of such compact construction that the . 3Q space occupied by the adjustment mechanism is as small as .-:
E~ ~, ~63~50 possible.
According to the present invention there is provided a device for adjusting a motor car mirror around two substan-tially perpendicular axes, comprising: a housing; a reversible motor in said housing; an electromagnetically operated clutch in said housing and connected to said motor; two planetary ;
transmission assemblies in said housing and to which said clutch is connected for operating one or the other of said transmission assemblies, each transmission assembly having a drive shaft; a drive member mounted on each drive shaft; and - first and second mirror adjustment units, each having one end connected to the drive member on the drive shaft of a respective one of said transmission assemblies and having another end adapted to be connected to a mirror structure for tilting said mirror structure around a respective one of said axes.
With this structure, the forces required to adjust -the mirror can be directly transmitted to the mirror structure, so that the cable system and the necessary guiding means, with their attendant problems, can be dispensed with.
Each drive member may be a crank arm mounted on the associated drive shaft by means of a slip coupling.
In a preferred embodiment, the first mirror adjustment unit is located in the housing of the device, between the motor and a combined clutch/transmission mechanism, this mirror adjustment unit consisting of a disk-shaped element with a substantially heart-shaped aperture. The crank arm is inside the aperture and is engaged with a part of the disk-shaped element on an opposite side of the drive shaft from the mirror.
The part of this element toward the mirror structure has a cross-plate with two members extending in the direction of the .~
::
~ -4_ ~ 63~SO ~ `
. ~ :
axis around which the first adjustment unit tilts the mirror structure. These members are pivotally mounted within the housing. Two further members extend perpendicular to the first two members and extend out of the housing. Means are provided ;
for pivotally mounting the mirror on the latter two members for tilting movement about an axis in their direction. The second ~ ~-mirror adjustment unit is of corresponding construction and is located at the side of the combined clutch/transmission mechanism opposite to the motor, while the part of the disk-shaped element toward the mirror structure projects outside the housing for connection to the mirror structure.
; The parts of both mirror adjustment units which are adapted to be attached to the mirror structure can be snap fits into corresponding recesses in this plate.
The compactness of the device may be further improved if the axes of the driving motor, the clutch and the planetary transmission assemblies are in line with each other. Moreover, the clutch and the planetary transmission assemblies may be located in a common, cylindrical housing, the two planetary transmission assemblies being at either extremity of this housing, while between them are mounted a spring biased clutch~
member and a magnetic core for moving the clutch member against the spring bias for coupling the motor with one or other of -~
- the planetary transmission assemblies.
Under adverse conditions, when mounted on a vehicle, the adjustable motor car mirror may exhibit undue vibration.
It has been found that, under extreme conditions, the mirror proper may exhibit an annoying vibration of its own relative to the vehicle, caused mainly by the vortex pattern of the air flowing along the edges of the mirror into and out of the '~
~C163~5~
.:
housing. It has moreover been found that these air currents may introduce dirt and dust into the adjustment mechanism, so that it is necessary for this mechanism to be provided with a separate dust cap, for example, of rubber.
To suppress vibrations and seal against dust, the -n embodiments may be provided wherein said housing includes a cylindrical wall around said motor, clutch and transmission assemblies, with a sealing edge thereon, and including a tilting adjusting ring having a spherical surface thereon in sliding sealing engagement with said sealing edge and having means thereon for holding a mirror mounting plate on said adjusting ~; ring.
By having the mirror adjusting units act on a tilting adjusting ring the advantage is obtained that, irrespective of the position of the mirror, this ring can remain in contact i with the sealing edge of the housing, so that frictional forces are introduced which increase the resistance against unintention-~; al tilting movements of the mirror and thereby also act to dampen vibration. Additionally, this arrangement provides for dust-tight sealing between the rear surface of the mirror mounting plate and the housing, so that dirt is unable to penetrate into the adjusting mechanism, and a separate dust cap can be omitted.
In a preferred embodiment of this apparatus, in order to eliminate effects of the friction of the sealing edge on the adjusting ring that adversely affect the adjustment, the adjusting ring is provided with at least two inwardly extending - dogs located adjacent to the circumference of the adjusting ring, said dogs being angularly spaced apart a distance of 90 and having recesses capable of receiving the extremities of the ~.~ -6-~0638,50 ~ ~
mirror adjusting units by means of a snap connection. sy virtue of the fact that the points of connection for the adjusting units are disposed a relatively large distance from the centre, a stable construction, free from vibration is produced.
; In order that the mirror may be easily mounted on the apparatus, the adjusting ring is preferably provided with an .
outwardly projecting flange, the mirror mounting plate having -a corresponding flange with a plurality of dogs capable of engaging around the projecting flange of the adjusting ring. ~ -The housing for receiving the adjusting mechanism may he of bipartite construction, with the boundary face between the two parts extending parallel to the plane of the adjusting ring in a neutral position, the parts of the housing in mounted condition forming the bearing for the mirror drive mechanism, a bottom part of the housing being formed as a dust cap, and the assembled housing being provided at the corners of a top `
housing part with apertures for securing the apparatus in`a ~ ~
protective cap suitable for being mounted on a vehicle. ` -Motor car mirrors are often housed in housings suitable for being mounted, for example, on the door of a vehicle. These housings commonly consist of a protective cap and a mounting column. Safety rules prescribe that these protective caps must be capable of pivoting about the mounting column when a certain force is exercised on them. ;
Thus, there is also provided the combination of an ~ -.: . .
adjusting device as described with a safety housing for mounting -~` the device. The safety housing comprises a protective cap having two integral, substantially parallel partitions spaced ; 30 apart so as to be capable of receiving the top part of a ii ~ .' ` ' -'~

~ -7-,' ,, ~063850 mounting column between them and a clamping means for clamping the partitions against the surface of the top part of said mounting column.
Preferably, the top part of the mounting column is provided with an axial notch, while one of the partitions has a ::
correspondingly shaped projection, which is pressed into the - .
notch by a resilient metal clip.
; There is thus produced a highly simple construction in which the protective cap cannot be misadjusted, for example, ~ 10 by the wind as the vehicle is in motion, whereas, when an impact force is exercised on the protective cap, the protection can move out of the notch, and the cap can pivot ; about the mounting column. This construction is particularly .'''''~ . .

suitable when the cap consists of plastics, so that the partitions between which the top shaft portion of the column is received can be provided as the cap is formed.
In another embodiment of the safety housing, the latter is formed so that it can also function as the bottom -member of the housing fQr the adjusting mechanism. For ~this purpose the protective cap of the safety housing is formed ~ -~

crank-shaped dog 13 is pressed onto the drive shaft or hub of the planetary transmission assembly 11 in such a manner that .
it can slip upon the hub. A crank-shaped dog 14 is likewise pressed onto the drive shaft or hub oE the planetary ~i transmission assembly 12 and can also slip upon the hub. The electric power leads for the motor 7 and the coil 9 are , numbered 15.

The extremity of the crank engages in an aperture in the mirror ~ -adjustment unit 3 and causes the latter to pivot on the axis 36. -The upper part of the mirror adjustment unit 3 takes the form of a cross-piece 40, of which the members extending in the direction o the longitudinal adjustment axis 36 of the mlrror 2 are enclosed within the housing 5 ~see Fig. 5), ':, ' ~.

while the membexs 19 which are perpendicular to the adjus-tment axis 36 project outside the housing 5. The extremities oE
these members 19 are fashioned in such a manner that the mirror mounting plate 2 can be snap ~Eorced upon them by means of corresponding recesses in the mirror mounting plate.
When the mirror has been pivoted through a certain ~ -angle, the mounting plate 2 will come to rest against the housing 5. I~ the shaft or hub 16 of the planetary transmisslon assembly 12 continues to be driven`with the mirror in this position, the crank-shaped dog 14 will commence slipping on the hub 16. This slipping is also of importance when a force, ~or example, a blow, is delivered to the mirror mounting plate
2 which is not intended to be transferred to the planetary transmission assembly 12. The transmission can thus not be damaged by forces exerted on the mirror.
Fig. 4 illustrates a similar arrangement for adjusting the mirror about an axis perpendicular to the longitudinal axis. Since the-second mirror adjustment unit 18 is not located in the centre of the mirror, this unit must be capable of oscillation in the vertical direction (see Fig. 1). This requirement is achieved by means of the-crank-shaped dog 13, which is pressed onto the drive shaft or hub 17 of the planetary transmission assembly 11, this dog 13 being horizontal ~.
in the neutral position and arranged to engage in an aperture ~
. ~
in the mirror adjustment unit 18. When the dog 13 is rotated, the mirror adjustment unit 18 is caused to move~upwards or downwards in the vertical direction, this movement being transmitted to the mirror through the projecting element 4. ~-This element 4 is engaged by snap Eorcing in a corresponding recess in the mirror mounting plate 2~ As indicated in Fig. 5, 1~9631~50 ~
the element 4 can be an integral part of the mirror adjustment unit 18 Fig. 5 illustrates on an enlarged scale the construction of the cylindrical housing 8 and the parts cortained wi-thin it. The housing 8 consists of two cylindrical rings 25 and 26, while the left- and right-hand portions are occupied respectively by the planet wheel 16' of the planetary transmission assembly 12 and the planet wheel 17' of the planetary transmission assembiy_ll. The planet wheels 16' and 17' are able to rotate within the housing 8. This housing also , contains the coil 9 and the coil casing 24, which are retained by the rings 25 and 26 of the housing 8.

The motor 7 is secured within the housing 5 by means of the centering rings 22, while the drive shaft 23 of the motor 7 is coupled to the interlocked parts 29 and 30 of the clutch shaft by a keyed connection. The clutch sleeve 28, which is pressed into the magnetic core 27, is located between the - parts 29 and 30. In~the drawing, this clutch sleeve 28 is Shown urged to the right by the spring 31. In this position, `~
- :., the clutch shaft 29 is in engagement with the solar wheel 33 of the planetary transmission assembly 11. When the coil 9 is activated, the magnetlc core 27 is caused to move to the left, so that the clutch shaft 30 engages the solar wheel 34 of the planetary transmission assembly 12. By the above means, the ~ -~
;~ mirror is either adjusted about an axis perpendicular to the drawing plane by the upward or downward movement of the mirror ; adjustment unit 1~, or it is adjusted about an axis lying in the drawing plane when the solar wheel 34 is driven.

- The planetary transmission assemblies ll and 12 are both duplicated and make it possible to achieve a gearing reduction of 3000 : 1. This is arrived at in the following manner (see also Fig.6) The solar wheel 34 is/engagement with three satellites 35 which are each provided with a double set of teeth, which differ slightly, for example by one tooth, in the number of teeth they present. The`set of teeth of the ;~

which dif~ers slightly from the number of teeth on the interior .
wall of the ring 25 of the housing 8. When the solar wheel 34 is driven, and because the ring 25 is stationary, the .
satellites 35 will~roll over the teeth on the interior wall of this ring-25. Since these satellites 35 are also in :-' '.. - , : ~ :
- 20 engagem~nt with the teeth borne by the planet wheel 16' via the second set of teeth borne by these satellites 35, the planat wheel 16' wilI be displaced by the angular e~uivalent of one tooth with respect to the ring 25 for every revolution ~ ;
o~ the satellites 35, because there is-a difference of one in the~number of teeth presented by the two sets of teeth of each~satellite. In this manner, the substantial gearing ; reduction mentioned above is achieved.
The plane-tary transmission assembly 11 is identical to the planetary transmission assembly 12 described above.

The particular feature of the safety housing shown: in~ -; Fig. 17-19 is that it has been achieved by simple means that `
when cap 140 is subjected to a heavy impact load it can pivot around shank portion 146. To this effect partitions 155 and 156 are arranged within cap 140, spaced apart so as to `, fitting receive shank portion 146 between them. Cap 14 `~ consists of a suitable plastics material, so that partitions . I . . 155 and 156 can easily be formed integrally with, and together with it.
