Definitions
- the present invention relates to a mechanism with a torque-limiting device for controlling a rearview mirror.
- a device for controlling a vehicle rearview mirror, in which the mirror is fixed on a supporting member mounted for pivoting about two perpendicular axes on a yoke integral with a casing mounted in a cup-shaped member.
- the casing contains two pinions which are driven in rotation by driving members.
- the pinions are each provided with a central hole in which is engaged the threaded part of a tubular element integral with control members hinged on the rear face of the mirror supporting member in order to communicate a pivoting movement to the mirror supporting member about the two perpendicular axes.
- the pinions being driven in rotation by electrical motors, it is necessary to provide a torque-limiting mechanism in order to allow the threaded portion of the control member to disengage from the tapped hole provided in the pinions whenever a pressure is applied axially on the control members by pushing or pulling, especially when the mirror comes to a stop at the end of a stroke.
- the elements with very strict tolerances are numerous and include endless screw wheels which are mounted inside upper and lower casings to allow the rotation of the screws resting on the bottom of the lower casing by a semi-spherical bottom and by a sliding surface of shape corresponding to a curved surface situated on the lower part of the screws. This obviously gives rise to major manufacturing difficulties.
- the tubular extension with the threaded portion of the control members is produced from a deformable material and is provided with at least one axial slot issuing into one of the ends of the tubular extension in such a way that any force applied axially on the control member enables the thread to disengage from the tapped hole in the central boss, and the pinions are mounted on the bottom of a casing by way of a ball joint which is resiliently held in position so that the control members are always in alignment with the axis of the driving pinions.
- this configuration enables elimination of the washer and the screw and results in reduced assembly time, thus lowering the manufacturing costs.
- the ball joint is fitted in by exerting a pressure thereon so as to resiliently spread apart the flexible members of the bearing, and to hold the ball in position without play when the flexible members return resiliently into place, permitting nonetheless the rotation of the ball when the mirror-holder is moved.
- the improved device according to the present invention can work freely, without play and with a play take-up supplied by the resilient element composing it.
- FIG. 1 is an external view of the mechanism for controlling a rearview mirror
- FIG. 2 is an elevational view of a cross-section along line II--II of FIG. 3 of the mirror controlling mechanism, the upper cover being removed on the side of one of the motors;
- FIG. 3 is an offset cross-sectional view along line III--III of FIG. 2 and of the lower part and of the cover of the casing;
- FIG. 4 is an elevational view of a cross-section of the torque-limiting device and of the mechanism for mounting a pinion on the base of the casing;
- FIG. 5 is an elevational view of a cross-section of an alternate embodiment of FIG. 4.
- the control device includes a cup-shaped member, not shown, in which is mounted in a known manner a casing 1 on which a mirror 2 is fitted so as to be pivotable about two perpendicular axes XX1 and YY1, the casing 1 having a cover 1a removably secured thereto.
- the mirror 2 is secured to a supporting member 3, provided with two lugs 4, by which the supporting member 3 is mounted for pivoting about the axis XX1 which is connected by known means to the axis YY1 and to a yoke 5 of the casing 1.
- spherical bearing 35 as illustrated in FIG. 4, is defined by an extended sleeve portion 38 in deformable material and at the bottom 39 of the boss 36.
- the extended sleeve portion of the boss has a central opening with a lip 37 which constitutes the edge of the opening of the extended sleeve portion of the boss which engages the spherical member or ball joint 34.
- the tangent wheels or pinions 6 and 6a mesh externally respectively with endless screws or pinions 9 and 9a.
- the endless screws or pinions 9 and 9a are respectively fixed on axles 10 and 10a which carry the pinions 11 and 11a which in turn mesh with the pinions 12 and 12a wedged on the end of the driving shafts 13 and 13a of the electric motors 14 and 14a fixed on the bottom of the casing.
- the tangent wheels or pinions 6 and 6a are provided with a central boss 15 and 15a having a threaded hole 16 and 16a (not shown) in which is engaged a threaded end portion 17 and 17a (not shown) of a tubular extension 18 and 18a of a control member 30 and 30a.
- the flanged end 19 and 19a of the control member 30 and 30a carries a ball joint 20 and 20a.
- the ball joint 20 and 20a is provided with lugs 21 and 21a which engage inside a corresponding spherical housing provided in a boss 22 situated on the rear face of the supporting member 3 as shown in FIG. 1, the lugs 21 and 21a serving to prevent rotation of the control members 30 and 30a as they are driven axially by the rotation of the pinions 6 and 6a.
- the flanged end 19 and 19a of the control member 30 and 30a which extends outside of the casing through openings provided, therefore, is connected by way of deformable bellows 23 and 23a to the rims of the openings to provide a seal between the flanged ends 19 and 19a and the openings in the casing 1.
- the tubular extensions 18 and 18a of the control members 30 and 30a are produced from a deformable material, such as plastic, and are provided with axial slots 24 and 24a extending from one end of the tubular extension, so as to permit the tubular extension to deform radially when an axial force is applied on one of the control members.
- the axially applied force causes a disengagement of the threads on the threaded end portion 17 from the threads in the threaded hole 16.
