Abstract

This invention relates to a shiftable outside mirror for use on a motor vehicle having a turn signal lever arm to eliminate a driver'"'"'s blind spot. The turn signal lever arm is provided with a switch at its free end. The invention comprises a switch capable of being articulated about the end of the turn signal lever arm from a rest position in a plane parallel to the plane of motion of the turn signal lever arm to an activated position in which the position of the mirror is altered. The switch is moved counter-clockwise to shift a left outside mirror, and clockwise to shift a right outside mirror.

Claims

1. A shiftable outside mirror for use on a vehicle having a turn signal lever arm and switch means operable to shift said mirror, wherein the improvement comprises:

said switch means being pivotally mounted on said turn signal lever arm, pivotal relative to said turn signal lever arm in a plane substantially parallel to the plane of motion of said turn signal lever arm from a rest position to an activated position in which the mirror is shifted;

said switch means being movable with said turn signal lever arm when in said rest position such that only a turn signal is actuated;

said switch means being movable with said turn signal lever arm when in said activated position such that said mirror is shifted and a corresponding turn signal is actuated, and said shiftable outside mirror having a planar mirror element and motor means for rotating said element about an essentially vertical axis.

2. Apparatus as defined in claim 1 wherein the longitudinal axis of said switch means in its rest position is essentially a continuation of the longitudinal axis of said turn signal lever arm.

3. Apparatus as defined in claim 2 wherein an end portion of said turn signal lever arm and an end portion of said switch means are formed ton interfittingly engage each other, with spring means engaging both end portions.

4. Apparatus as defined in claim 3 wherein said spring means comprises a U-shaped spring having two free ends and a base, the free ends engaging said end portion of said switch means, said base engaging said end portion of said turn signal lever arm.

5. Apparatus as defined in claim 3 wherein said spring means biases said switch means to said rest position, the force required to move said switch means from said rest position being less than the force required to move said turn signal lever arm.

6. Apparatus as defined in claim 3 wherein said end portion of said switch means comprises two opposed, curved tongue portions surrounding said end portion of the turn signal lever arm.

7. Apparatus as defined in claim 6 wherein an elastic cover covers the interfitting engagement of said switch means and said turn signal lever arm.

8. Apparatus as defined in claim 6 wherein the end of at least one of said tongue portions is provided with at least one electrical contact, said turn signal lever arm adjacent said tongue portion is also provided with at least one electrical contact, said electrical contact on said tongue portion and said electrical contact on said turn signal lever arm engaging upon pivoting of said switch means.

9. Apparatus as defined in claim 8 wherein the position of said outside mirror is shifted in response to said switch means by way of electrical actuating means having a first circuit comprising said electrical contact on said tongue portion of said switch means, said electrical contact on said turn signal lever arm, a relay, and a control system, and a second circuit comprising a motor rotatable in two directions connected to said outside mirror for the purpose of shifting said outside mirror, two shift field limit switches to limit the shift field of the mirror, and two motor switches actuated by said relay to turn said motor on and off;

said control system operative to turn said relay on for a preset period of time in response to a brief contact between said electrical contact on said tongue portion of said switch means and said electrical contact on said turn signal lever arm, and a correspondingly longer period of time for more sustained contact.

10. Apparatus as defined in claim 9 wherein said first circuit is electrically connected to a branch circuit comprising the opposite side turn signal by means of a branch circuit switch in such a manner that said outside mirror cannot be shifted when current is flowing through said branch circuit.

11. For use in combination with a vehicle having a turn signal actuator:

a rearview mirror for outside mounting on a motor vehicle having a planar mirror element and motor means for rotating said element about an essentially vertical axis;

motor means connected to said mirror for shifting same from one viewing angle to another;

switch means pivotally mounted on said turn signal actuator, pivotable independently thereof to actuate said motor means; and

means connecting said motor means to the turn signal actuator such that operation of said actuator simultaneously operates said motor means and a corresponding turn signal.

12. A motor vehicle outside rearview mirror assembly for use in combination with a turn signal actuator lever comprising:

a rearview mirror having a planar mirror element and a motor for rotating the element about an essentially vertical axis; and

a manually-actuable switch electrically connected to said motor and being mechanically mounted on said actuator lever so as to be movable both independently thereof and simultaneously therewith, whereby said lever and said switch are selectively simultaneously operable such that said mirror is shifted and a corresponding turn signal is actuated.

13. Apparatus as defined in claim 12 wherein said switch is mounted so as to form an extension of said lever.

14. A shiftable outside mirror for use on a vehicle having a turn signal lever arm and switch means operable to shift said mirror, wherein the improvement comprises:

said switch means being pivotally mounted on said turn signal lever arm, pivotal relative to said turn signal lever arm in a plane substantially parallel to the plane of motion of said turn signal lever arm from a rest position to an activated position in which the mirror is shifted;

said switch means being movable with said turn signal lever arm when in said rest position such that only a turn signal is actuated;

said switch means being movable with said turn signal lever arm when in said activated position such that said mirror is shifted and corresponding turn signal is actuated, said shiftable outside mirror having a planar mirror element and motor means for rotating said element about an essential vertical axis;

wherein

the longitudinal axis of said switch means in its rest position is essentially a continuation of the longitudinal axis of said turn signal lever arm, such that an end portion of said turn signal lever arm and an end portion of said switch means are interfittingly engaged by spring means engaging both of said end portions, said spring means comprising a U-shaped spring having two free ends and a base, the free ends engaging said end portion of said switch means, said base engaging said end portion of said turn signal lever arm.

15. Apparatus as defined in claim 14, wherein said spring means biases said switch means to said rest position, the force required to move said switch means from said rest position being less than the force required to move said turn signal lever arm.

16. Apparatus as defined in claim 14, wherein said end portion of said switch means comprises two opposed, curved tongue portions surrounding said end portion of the turn signal lever arm.

17. Apparatus as defined in claim 16, wherein an elastic cover covers the interfitting engagement of said switch means and said turn signal lever arm.

18. Apparatus as defined in claim 16, wherein the end of at lest one of said tongue portions is provided with at least one electrical contact, said turn signal lever arm adjacent said tongue portion is also provided with at least one electrical contact, said electrical contact on said tongue portion and said electrical contact on said turn signal lever arm engaging upon pivoting of said switch means.

19. Apparatus as defined in claim 18, wherein the position of said outside mirror is shifted in response to said switch means by way of electrical actuating means having a first circuit comprising said electrical contact on said tongue position of said switch means, said electrical contact on said turn signal lever arm, a relay, and a control system, and a second circuit comprising a motor rotatable in two directions connected to said outside mirror for the purpose of shifting said outside mirror, two shift field limit switches to limit the shift field of the mirror, and two motor switches actuated by said relay to turn said motor on and off;
