Method and apparatus for temporary view shifting of vehicle side mirror
First Claim
1. In an apparatus including a mirror mounted on the side exterior of a vehicle for temporarily shifting the viewing angle of the mirror to an angle other than an angle to which the mirror has been preset by the vehicle operator for use during normal driving, said apparatus including:
- a base member providing said preset viewing angle of said mirror;
said mirror, when at said preset angle, lying in a generally vertical plane and at an angle substantially perpendicular to said vehicle;
electrically-operable operating means mounting said mirror for limited, essentially instantaneous pivotal movement about a predetermined axis relative to said base member;
a normally-open momentary contact switch accessible to said operator from within said vehicle, said switch being physically activatable and maintainable by said operator in a closed position for energizing said operating means, said switch being dedicated solely to pivot said mirror relative to said base member about said axis to a second angle;
said switch including biasing means quickly restoring said switch to its normally open position to deenergize said operating means and thereby pivoting said mirror from its second angle to said first angle upon discontinuation of physical activation of said switch; and
,means for stabilizing said mirror in both its preset and second angles.

Abstract
A method and apparatus are provided to allow the operator of a vehicle wishing to change traffic lanes to temporarily scan an angle of the passing lane which is in his or her "blind spot", i.e., an area outside the normal angle of viewing of a conventional flat side rear view mirror. The invention is also useful to divert the headlight reflection from a vehicle in a passing lane out of an operator'"'"'s eyes. Accomplishment is through temporary pivotal movement of the side mirror to shift the mirror viewing angle from the position at which it had been preset by the operator for normal driving.

4. In an apparatus including a mirror mounted on the exterior of a vehicle for viewing by the operator of said vehicle in one traffic lane of other vehicles in an adjacent passing traffic lane while said operator maintains attention ahead in said operator'"'"'s own traffic lane, said apparatus including:
-
a base member providing a first normal viewing angle of said mirror; said mirror, when at said first angle, lying in a generally vertical plane and at an angle substantially perpendicular to said vehicle; means pivotally mounting said mirror about an essentially vertical axis relative to said base member; means controllable by said operator for adjusting said base member to said first normal viewing angle position to monitor vehicles alongside and behind said vehicle in said passing lane; electrically-operable operating means mounting said mirror to said base member; a normally-open momentary contact switch accessible to said operator from within said vehicle, said switch being physically activatable and maintainable by said operator in a closed position for energizing said operating means, said switch being dedicated solely to pivot said mirror relative to said base member about said vertical axis to a second rear viewing angle to momentarily scan a blind spot location in said passing lane slightly rearwardly of said vehicle, said blind spot location being a location in said passing lane normally not observable through said mirror when said mirror is at said first angle; means biasing said switch to its normally-open condition to deenergize said operating means and restore said mirror from its second to said first angle upon physical release of said switch; and said operating means including stabilizing means for firmly locking said mirror in both said normal and rear viewing angles. - View Dependent Claims (5, 6, 7, 8, 9)
