Dual-arm linear slide mechanism for an extendable rearview mirror for vehicles
First Claim
1. An extendable rearview mirror assembly for a vehicle, comprising:
- a support arm for attachment to a vehicle body by a mirror mount comprising first and second legs separated by a substantial void which extends along the support arm forming separated horizontal parallel segments;
a mirror assembly mounted on said support arm, said mirror assembly including a bracket and a surrounding housing affixed thereto;
a mirror subassembly affixed to a first side of the bracket and lying within said housing; and
clamp means on said bracket for slidably affixing said bracket to said support arm, comprising;
a first jaw being stationary with respect to said bracket and engaging a first guide rail located along one edge of said support arm; and
a second, movable jaw including pivot means, said second jaw forceably engaging a second guide rail located along a second edge of said support arm.

Abstract
An extendable outside rearview mirror for a vehicle includes a spring-clamped slide mechanism that ensures a zero clearance fit between sliding components to avoid vibration. Bearing members between the sliding components reduce friction and provide a consistent reaction force to ensure smooth operation of an actuator mechanism which extends or retracts the mirror assembly along a support arm. The support arm includes V-shaped guiderails vertically aligned with opposing V-shaped guiderails on the mounting bracket assembly. Rod-like bearing means are interposed between the opposing guiderail pairs. A cantilever clamp jaw with spring means biases one guiderail toward the other with a high spring force which provides superior rigidity and thus enhanced mirror image clarity. The attachment end of the support arm may be divided into two attachment legs providing a dual-arm configuration for less wind resistance.
