Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 261 words
An auxiliary mirror angle changing device for a main and auxiliary rearview mirror comprising; a main mirror frame; an auxiliary mirror frame normally being moved in the interior of the main mirror frame and possible to be moved sidewise out of the main mirror frame by a motor connected with a reduction gear set to rotate a worm inserting and engaging in a threaded hole in the rear end wall of the auxiliary mirror frame, said motor being started by a switch and stopped by one of two micro switches fixed respectively at the front end and the rear end of the main mirror frame, said micro switch being actuated by touching of one of two touch blocks provided on and under the rear end wall of the auxiliary mirror frame, said auxiliary mirror frame possible to be inclined in its angle by a device comprising; a digital motor mounted in said auxiliary mirror frame; a control electric circuit having its output connected with the digital motor for rotating the digital motor clockwise or counterclockwise and connected with the micro switches which can start said control electric circuit when it is touched by one of the touch block; and a base connected with the shaft of the digital motor enveloping said motor in its interior and being inclined backward or forward by clockwise or counterclockwise rotation of the digital motor to press a plurality of springs fixed on the back of the auxiliary mirror to incline said mirror to a certain angle wanted by pushing up or down a control switch.
