Description
The present invention relates to a remote-control device for a vehicle rearview mirror.
Certain motor vehicles, and in particular luxury vehicles, are designed to be equipped on the passenger side with a rearview mirror controlled by an electric motor. Prior to the present invention, these mechanisms have been too expensive to be fitted on less expensive, or standard vehicles.
Moreover, the mechanical control devices previously known, which use three transmission cables, do not accurately transmit the movement to the mirror, due to excessive length of the transmission members.
Summary of the Present Invention
It is the object of the present invention to provide an improved remote control device for a vehicle rearview mirror. In particular it is the object of the present invention to provide a remote control device having a control member situated inside the vehicle and connected, via two transmission cables, to means for actuating the mirror situated inside the rearview mirror housing, which is mounted to the exterior of the vehicle.
According to the present invention, the rearview mirror housing is provided with a support member on which a crosspiece is mounted for pivoting about a vertical axis. The crosspiece is equipped with a mirror support mounted for pivoting about a horizontal axis, and is pivotally mounted to one end of one of the transmission cables the support is a pivot on which an elbow-shaped lever is pivotally mounted at its center. One end of which lever is connected to one of the transmission cables. The other end thereof is connected to the mirror support, by way of a hinged finger, at a point which is offset with respect to the horizontal pivoting axis of the mirror support on the crosspiece.
The remote control device according to the invention uses control means and actuating means having simple kinematic characteristics, in order to allow a reliable and accurate control of the mirror at a reasonable cost. The device can be used for the passenger-side rearview mirror, on the left or right side of a motor vehicle.

Detailed Description of the Preferred Embodiment
Referring now to the drawings, generally illustrating a remote control apparatus according to the present invention, FIGS. 1 through 5 show a rearview mirror control device 100 of the remote control apparatus which is connected by two transmission cables 10 and 11 to a mirror actuating device 101 of the remote control apparatus, illustrated in FIGS. 7 through 10. The control device 100 includes a support member 1 with a projecting portion 1a which is engaged in an orifice provided in a wall 2 inside the vehicles. The support member 1 is mounted to the wall 2 by any appropriate known means.
The support member 1 is provided with two parallel grooves 3 and 4 which are located in two perpendicular planes, as best shown in FIG. 4. The transmission member 5 is mounted in a groove 3, as shown in FIGS. 3 and 5. A transmission member 6 is mounted in the groove 4 as shown in FIG. 1. Each of the transmission members 5 and 6 has a rectilinear portions 5a and 6a, respectively, as shown in FIGS. 1, 3, 5 and 6, mounted for sliding in the grooves 3 and 4. The portions 5a and 6a are provided at one of their ends with recesses 7 in which are engaged bosses 8 and 9, respectively secured on the ends of the transmission of control cables 10 and 11. The control cables 10 and 11 are slidably fitted in sheaths 12 and 13, respectively, one end of which is secured on a bracket 1b of the support member as best depicted in FIGS. 1 and 5.
The rectilinear portions 5a and 6a of the transmission members 5 and 6 are extended by rounded portions 5b and 6b, respectively, as shown in FIGS. 1, 2, 5 and 6. A slot 14 is provided in the rounded portion 5b of the transmission member 5, which slot is located in a plane perpendicular to the sliding axis of the transmission member 5. A spherically shaped finger 15 is formed integrally with a brace 16 and is engaged in the slot 14. A control lever 17 is interconnected with the brace 16 and extends therefrom through an orifice 18 provided in the projecting part 1a of the support member through the wall 2. The finger 15 is directed along the same axis as the lever 17. The brace 16 is pivotally mounted by way of a pivot pin 19, as shown in FIGS. 2 and 3 on the end of a stem 20 which in turn is rotatably mounted inside a bearing 21 formed integrally with the support member. The stem 20 is held in position by an elastic washer 22. The pivot pin 19 is disposed perpendicularly to the rotational axis of the stem 20.
The pivot pin 19 is extended by a spherical swell 19a, as depicted in FIG. 2 which is engaged in a slot 23 provided in the rounded portion 6b of the transmission member 6. The slot 23 is inclined with respect to a plane perpendicular to the sliding axis of the transmission members 5 and 6.
FIGS. 7 through 10 show a rearview mirror housing 24 and a mirror actuating device 101. A support member 26 is fitted, by way of a screw 25, to the inner surface of the housing 24. The support member 26 is extended at the front by a fork member 26a, best shown in FIGS. 7 through 9, which is provided with recesses in which pivots 27 and 27a of a crosspiece 28 are engaged. The crosspiece 28 also has pivots 29 and 29a, as shown in FIGS. 7 and 9, which are engaged in corresponding recesses provided in a fork 30 fitted on the rear face 31a of a mirror support 31 shown in FIGS. 8 and 9.
At the end opposite the pivots 27 and 27a, the crosspiece 28 includes a recess in which is engaged a boss 32 secured to the end of the cable as shown in FIG. 9. The sheath 13 of the cable 11 rests against an abutment 33 which is hingedly mounted, by way of pivots 34 and 34a, in recesses provided on the support member 26. Also provided on the support member 26 is a fork 35, shown in FIGS. 7 and 10. An elbow-shaped lever 37 is pivotally mounted betwen the shanks of the fork 35 for pivoting in the center and about a pin 36. One of the ends of lever 37 is provided with a hemispherical recess 37a. A finger 39 is provided at one end thereof with a knuckle head 38 engaged in the hemispherical recess 37a and at the other end thereof with a knuckle head 38a engaged in a recess 40 provided in the rear face 31a of the mirror support 31. The pivoting point of the finger 39 on the mirror support 31 is offset with respect to the horizontal pivoting axis defined by the pivot 29 and 29a of the mirror support 31 on the crosspiece.
At the other end of the lever 37, there is provided a recess in which is engaged a boss 41 attached to one end of the cable 10. The sheath 12 of the cable 10 rests against an abutment pivotally mounted to the support member 26 by way of pivots 43 and 43a in corresponding recesses provided on the support member 26.
The cables 10 and 11 can be constituted by rigid hardened steel wires of the piano-chord type, which are placed inside the sheaths 12 and 13 of plastic material reinforced with steel wires. It is also possible to use flexible cables of the type generally known under the name Bowden cables. In this latter case, however, it is necessary to provide elastic return means 44 first between the lever 37 and the support member 26, and elastic, return means 45 between the crosspiece and the housing 24. In this later case, it is preferable in order to overcome the return force of the elastic members to provide braking means at least on the hinged connection of the control lever 17 or on each one of the transmission members 5 and 6.
The device according to the invention operates as follows. When the lever 17 is actuated as illustrated in FIG. 2 in order to pass from the position C.sub.0 to the positions C.sub.1 or C.sub.2, the stem 20 is caused to rotate inside the bearing 21 in such a way that the finger 15 moves inside the slot 14 without causing the transmission member 5 to move. On the other hand, the movement of the pivot pin 19 inside the inclined slot 23 causes the transmission member 6 to move in the direction of double arrow F in FIG. 1 inside the groove 4, as well as the movement of cable 10.
At its other end inside the housing 24, the cable 10 acts on the elbow-shaped lever 37 which pivots about the pin 36, thereby insuring, via the finger 39, the movement of the mirror-holder about the horizontal axis defined by the pivots 29 and 29a by an amount indicated by an angle .beta., and the consequent upward and downward movement of the mirror.
When the lever 17 is actuated, as shown in FIG. 3 in order to pass from the position C.sub.0 to the positions C.sub.3 or C.sub.4, the stem 20 remains stationary and the lever 17 pivots about the pivot pin 19, so that the finger 15 engaged in the slot 14 drives the transmission member 5 into motion. The transmission member 5 slides in the groove 3 in the direction of double arrow F.sub.1. The transmission member 5, by being interconnected with one of the ends of the cable 11, drives the latter to translate. At the other end of the cable 11 inside the housing 24, the cable 11 acts on the crosspiece 28, which pivots about the pivots 27 and 27a thereby insuring the movement of the mirror support 31 about a vertical axis as indicated by an angle .alpha. and thereby provides the left-right movement of the mirror.
The invention is in no way limited to the specific description given hereinabove. Modifications will be apparent to those skilled in the art which may be made thereto without departing from the spirit of the present invention or the intended scope of the claims appended hereto.
