Abstract

An outside back mirror device for use in an automobile which comprises an outside back mirror casing, a solenoid actuated by a drive circuit for turning on and off the power source for a certain time period, a hydraulic member for receiving the force applied by the solenoid so as to make a mirror move, a shock absorber for delaying the return of the mirror to its original position, and an elastic member including a fixing bolt and a spring for causing the mirror to return to its original position.

Claims

1. An outside back mirror device having a mirror for use in an automobile, which comprises:

an outside back mirror casing,

a solenoid actuated by a drive circuit for turning on and off the power for a certain time period,

a hydraulic member for receiving the force applied by said solenoid so as to make said mirror move,

a shock absorber for delaying the return of said mirror to its original position, and

an elastic member including a fixing bolt and a spring for causing said mirror to return to its original position.

2. The outside back mirror device of claim 1, wherein the drive circuit includes a NAND gate for generating a trigger signal according to the operation of a push switch and a time constant fixed by a variable resistance, first and second monostable multivibrators for generating a pulse according to said trigger signal, and transistors operatively associated with the solenoid according to the output of said first mono stable multivibrator and the solenoid interlocked with said transistors.

3. The outside back mirror device of claim 1, wherein a flanger of the hydraulic member touches the surface of the mirror for inclining the mirror.

4. The outside back mirror device of claim 1, wherein the hydraulic member includes a wire fixed the hydraulic member to the mirror for inclining the mirror.

5. The outside back mirror device of claim 1, wherein the hydraulic member includes a link lever and a rotary piece for inclining the mirror.

6. The outside back mirror device of claim 1, wherein the hydraulic member includes a sliding plate having a raised portion disposed on the middle of the sliding plate for inclining the mirror.
