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 mechanism at its free end. The invention comprises a switch mechanism 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 mechanism 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 said turn signal is actuated;

said switch means having a longitudinal axis which in its rest position is essentially a continuation of the longitudinal axis of said turn signal lever arm;

said turn signal lever arm having an end portion and said switch means having an end portion being formed to interfittingly engage each other, with spring means engaging both end portions;

said end portion of said switch means comprising two opposed, curved tongue portions surrounding said end portion of the turn signal lever arm; and

at least one of said tongue portions having an end that 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.

3. Apparatus as defined in claim 1, wherein the position of said outside mirror is shifted in response to said switch means by way of electrical actuating means having a first conduit 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.

4. Apparatus as defined in claim 3 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.

2. 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 said turn signal is actuated;

said switch means having a longitudinal axis which in its rest position is essentially a continuation of the longitudinal axis of said turn signal lever arm;

said turn signal lever arm having an end portion and said switch means having an end portion being formed to interfittingly engage each other, with spring means engaging both end portions;

said end portion of said switch means comprising two opposed, curved tongue portions surrounding said end portion of the turn signal lever arm; and

an elastic cover covering the interfitting engagement of said switch means and said turn signal lever arm.
