Abstract
Abstract A rear view mirror for a vehicle includes a member, providing a reflective surface and mounted so as to be swingable about a vertical axis, and an operating mechanism, which may be powered from the vehicle's battery or by a self-contained power unit, or other suitable electrical, mechanical, hydraulic or pneumatic means, which operating mechanism serves, under the control of the driver of the vehicle, to swing the member about its vertical axis between two preset positions so as to change the field of view presented by the reflective surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
A vehicle rear view mirror comprising: a housing, a reflective surface, operating means for swinging the reflective surface about a substantially vertical axis between two pre-set positions for changing the field of view presented by the reflective surface, the reflective surface being mounted within the housing about a substantially vertical fulcrum providing the vertical axis and being swingable about the fulcrum by the operating means, the fulcrum being provided at one side of the reflective surface, the reflective surface being supported by a plastic backing plate integral with a mounting arm extending from one side of the reflective surface, the fulcrum being a relatively thin strip of the plastic forming a transition between the backing plate and mounting arm, the operating means including a solenoid mounted within the housing and arranged to swing the reflective surface about the fulcrum between the first and second pre-set positions, a control switch electrically connected in series with the solenoid for controlling operation thereof, and an indicator lamp series-connected with a microswitch closable upon movement of the reflective surface into the second position with the indicator lamp being thereby switched ON for indicating the presence of the reflective surface in the second position.
Claim 2
Dependent Claim
199 words
A vehicle rear view mirror comprising: a housing, a reflective surface, operating means for swinging the reflective surface about a substantially vertical axis between two pre-set positions for changing the field of view presented by the reflective surface, the reflective surface being mounted within the housing about a substantially vertical fulcrum providing the vertical axis and being swingable about the fulcrum by the operating means, the fulcrum being provided at one side of the reflective surface, the reflective surface being supported by a plastic backing plate integral with a mounting arm extending from one side of the reflective surface, the fulcrum being a relatively thin strip of the plastic forming a transition between the backing plate and mounting arm, the operating means including a solenoid mounted within the housing and arranged to swing the reflective surface about the fulcrum between the first and second pre-set positions, a control switch electrically connected in series with the solenoid for controlling operation thereof, and an indicator lamp series-connected with a microswitch closable upon movement of the reflective surface into the second position with the indicator lamp being thereby switched ON for indicating the presence of the reflective surface in the second position.
Claim 3
Dependent Claim
23 words
A mirror as set forth in claim 1 in which the indicator lamp and microswitch are electrically connected in parallel with the solenoid.
Claim 4
Dependent Claim
211 words
A vehicle rear view mirror comprising: a housing, a reflective surface, operating means for swinging the reflective surface about a substantially vertical axis between two pre-set positions for changing the field of view presented by the reflective surface, the reflective surface being mounted within the housing about a substantially vertical fulcrum providing the vertical axis and being swingable about the fulcrum by the operating means, the fulcrum being provided at one side of the reflective surface, the reflective surface being supported by a plastic backing plate integral with a mounting arm extending from one side of the reflective surface, the fulcrum being a relatively thin strip of the plastic forming a transition between the backing plate and mounting arm, the operating means including a ferrous component movable with the reflective surface, an electromagnet mounted within the housing for acting upon the ferrous component to swing the reflective surface about the fulcrum between the first and second positions, and a control switch electrically connected in series with the electromagnet for controlling operation thereof, and an indicator lamp series-connected with a microswitch closable upon movement of the reflective surface into the second position with the indicator lamp being thereby switched ON for indicating the presence of the reflective surface in the second position.

Claim 6
Dependent Claim
23 words
A mirror as set forth in claim 3 in which the indicator lamp and microswitch are electrically connected in parallel with the electromagnet.
