Day-Night Mirror Control Apparatus
US Patent:
4103560, Aug 1, 1978
Filed:
Mar 17, 1977
Appl. No.:
5/778701
Inventors:
Robert W. Stoffel - Muskegon MI
Robert A. Berntsen - Muskegon MI

International Classification:
F16C 114
US Classification:
74501M
Abstract:
Remote control, day-night, outside rearview mirror control apparatus. The control structure includes a plurality of interconnection cables linking an orthogonally pivotable, double sided vehicle mirror and multi-axial actuation, operator control mechanism. Mirror movement in the form of yaw about the vertical axis thereof is facilitated via swivel motion of a control bat resulting in axial movement of cables terminating outwardly of the reference axis of the mirror. Mirror movement about the horizontal axis thereof, including 180. degree. flipping and control pitch adjustment, is facilitated through a single cable, double action mechanical servo which is responsive to axial and rotational control bat movement. The servo may be positioned adjacent the mirror or control bat and utilizes a spring loaded cam biased within a rotable casing to independently differentiate mirror pitch adjustment signals from day-night flip signals in a fashion which permits 180. degree. repositioning of the mirror to identical mirror viewing positions.
