Abstract
Abstract An outside mirror with a wiper is disclosed. The outside mirror includes a mirror drive motor and a wiper drive motor for a wiper. The wiper drive motor is mounted for rotation about an axis perpendicular to the mirror drive motor. The wiper is spring biased against the mirror to follow the movement thereof. As the mirror pivots about a vertical axis, a wiper guide urges the drive motor to pivot correspondingly so that the wiper follows the mirror surface. As the mirror pivots about a horizontal axis, the spring biased wiper follows the mirror to maintain the proper wiping contact with the mirror.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
231 words
An outside mirror with wiper comprising: (a) a mirror housing adapted for mounting on a vehicle; (b) a mirror affixed to and supported by a mirror support member; (c) vehicle operator-actuated remote control means mounted to said mirror housing and operably connected to said mirror support member for enabling the vehicle operator to pivotally adjust the position of said mirror about a mirror pivot point; (d) a wiper having a wiper blade fitted to one end of a wiper arm in position to sweep across the surface of said mirror, and a wiper drive motor having a drive shaft fitted to the other end of said wiper arm for reciprocally pivoting said wiper arm about said other end of said wiper arm in the manner of a winshield wiper; (e) wiper pivotal support means affixed within said mirror housing, said wiper drive motor being mounted on said wiper pivotal support means so that said wiper drive shaft rotatably swings about a substantially vertical axis extending through said mirror pivot point; (f) said mirror support member having guide means acting on said wiper drive shaft for urging said wiper drive shaft to pivot in a substantially horizontal plane in substantial angular correspondence with the pivoting action of said mirror; and (g) biasing means on said wiper for constantly urging said wiper blade to press against and follow the surface of said mirror.
Claim 2
Dependent Claim
