Abstract

An automotive remotely controlled rearview mirror assembly is remotely controlled from within an automobile for adjusting the angle of the reflecting surface of the rearview mirror to obtain a desired rear sight. The remotely controlled rearview mirror assembly comprises a housing adapted to be mounted on the automobile body by a mount, a mirror swingably supported in the housing, a control lever swingably mounted on the mount for remotely controlling the mirror for a desired angle thereof from within the automobile, and a link mechanism operatively interconnecting the mirror and the control lever and angularly movable vertically and laterally in response to swinging movement of the control lever. The link mechanism is angularly movable vertically about an axis which is inclined upwardly in a lateral direction away from a nominal vertical plane, and also angularly movable laterally about an axis which lies in a plane including a line substantially normal to a nominal horizontal plane.

Claims

1. A remotely controlled rearview mirror assembly for use on an automobile which has a longitudinal axis, which axis in nominally horizontal when the automobile is in a nominally horizontal state, comprising:

a mount securable on said automobile in a given orientation relative to nominal vertical and horizontal planes containing said longitudinal axis;

a housing adapted to be secured on said mount;

a mirror swingably supported in said housing;

a control lever swingably secured on said mount for remotely controlling said mirror to move to desired angular positions thereof from within the automobile; and

a link mechanism operatively interconnecting said mirror and said control lever and angularly movable vertically and laterally in response to angular and rotational movement of said control lever for moving said mirror to said desired angular position,

when said mount is secured in said given orientation, said link mechanism being angularly movable vertically about an axis which is inclined upwardly in a lateral direction away from a nominal vertical plane containing said longitudinal axis, and also angularly movable laterally about an axis which lies in a plane including a line substantially normal to said nominal horizontal plane containing said longitudinal axis whereby, when the mirror is moved to change the angle of the mirror relative to a vertical plane, the rear sight appearing on said mirror is not displaced laterally.

2. Apparatus according to claim 1 wherein said control lever has a first end, and said link mechanism comprises:

a first link having near and remote ends, its near end being pivotably coupled to said control lever;

a link holder pivotally secured to said housing; and

a second link having near and remote ends and a central part, the central part being pivotally mounted to said link holder, its near end pivotally coupled to said remote end of the first link and its remote end coupled to the mirror said link holder being secured to the central part of said second link by a pivot having a pivot axis that is oblique to a plane normal to the pivot axis about which the link holder is secured to said housing.

3. Apparatus according to claim 2 wherein said mirror is movably secured to said housing by a first ball-and-socket coupling, said mirror thus being movable about the center point of said coupling, and wherein said control lever is movably secured to said mount by a second ball-and-socket coupling, said control lever thus being movable about the center point of said second coupling when driven by said control lever so that a line between the centers of said ball and socket couplings is oblique to a plane normal to the axis of vertical motion of said link mechanism.

4. Apparatus according to claim 3 wherein a plane normal to the axis about which said link holder is pivotable is oblique to said axis of vertical motion which extends to said center point of said first ball-and-socket coupling from said pivot securing said link holder to said housing, said mirror being pivotable about this axis of vertical motion.

5. A remotely controlled rearview mirror assembly for use on an automobile having an automobile body which has a longitudinal axis, which axis is nominally horizontal when the automobile is in a nominally horizontal state, comprising:

a mount adapted to be fixed to the automobile body in a given orientation relative to nominal vertical and horizontal planes containing said longitudinal axis;

hinge means pivotally mounted on said mount and including a support plate;

a mirror holder swingably supported on said support plate;

a mirror mounted on a front surface of said mirror holder;

a control lever swingably mounted on said mount for remotely controlling said mirror to move to desired angular positions; and

a link mechanism operatively interconnecting said control lever and said mirror holder and angularly movable vertically and laterally in response to angular and rotational movement of said control lever for moving said mirror to said desired angular positions

when the mount is fixed in said given orientation, said link mechanism being angularly movable vertically about an axis which is included and extends upwardly in a lateral direction away from said nominal vertical plane containing said longitudinal axis, and also angularly movable laterally about an axis which lies in a plane including a line substantially normal to said nominal horizontal plane containing said longitudinal axis whereby, when the mirror is moved to change the angle of the mirror relative to a vertical plane, the rear sight appearing on said mirror is not displaced laterally.

6. A remotely controlled rearview mirror assembly according to claim 5, wherein said hinge means comprises a first swing frame swingably attached to said mount and a second swing frame swingably attached to said first swing frame, said support plate being fixedly mounted on said second swing frame, further including a spring acting between said support plate and said mount, said spring urging said swing frames to a nominal position where they are in mutually overlying relationship and said mirror holder extends outward from said automobile body, said spring allowing said mirror holder and second swing frame to swing forwardly and rearwardly relative to said mount.

7. A remotely controlled rearview mirror assembly for use on an automobile which has a longitudinal axis, which axis is nominally horizontal when the automobile is in a nominally horizontal state, comprising:

a mount securable on said automobile in a given orientation relative to nominal vertical and horizontal planes containing said longitudinal axis;

a housing adapted to be secured on said mount;

a mirror swingably supported in said housing;

a control means mounted on said vehicle for remotely controlling said mirror to move to desired angular positions thereof from within said vehicle; and

a link mechanism operatively interconnecting said mirror and said control means and angularly movable vertically and laterally in response to angular and rotational movement of said control means for moving said mirror to said desired angular positions,

when said mount is secured in said given orientation, said link mechanism being angularly movable vertically about an axis which is inclined upwardly and extends in a lateral direction away from said nominal vertical plane containing said longitudinal axis, and also angularly movable laterally about an axis which lies in a plane including a line substantially normal to said nominal horizontal plane containing said longitudinal axis whereby, when the mirror is moved to change the angle of the mirror relative to a vertical plane, the rear sight appearing on said mirror is not displaced laterally.
