Electrical remote-control mirror assembly
First Claim
1. An electrically remote-controlled type mirror assembly comprising:
- a mirror;
a mirror body supporting said mirror;
a casing having a ball-and-socket joint which supports said mirror body pivotally;
a pair of plungers coupled with said mirror body and so disposed within said casing as to be moved forward and backward by a pair of motors, respectively, by means of reduction gear trains, respectively, to tilt said mirror body horizontally and vertically within certain pivoting angles;
at least one of said plungers having an external thread formed on the outer circumference thereof and having a central hole provided along the center line thereof;
at least one nut member having an internal thread engaging said external thread of said one of the plungers and having at least one external thread member provided on the outer circumference thereof;
at least one hollow driving cylinder having formed on the inner circumference thereof an internal thread engaging said external thread member, and having formed on the outer circumference thereof a last-stage gear of said reduction gear train;
wherein said one of said plungers is moved together with said nut member to tilt said mirror body within said certain pivoting angles when said at least one driving cylinder is rotated by said motor, andat least one driving mechanism having another motor and other gear train which is driven by said another motor to rotate said one of the plungers relative to said nut member to tilt said mirror body beyond one of said certain pivoting angles;
wherein said driving mechanism includes,a driving shaft member including a rotary member having formed on the outer circumference thereof a last-stage gear of said another gear train, and a shaft slidably fitted in said central hole of said plunger so as to be blocked against pivoting relative to the plunger.said another motor which drives said another gear train, anda stopper means of limiting said pivoting angle of said mirror body, andwherein said one of the plungers screws forward and backward relative to said nut member to tilt said mirror body beyond said certain pivoting angles when said driving shaft member is rotated by said another motor.

Abstract
An improved electrical remote-control mirror assembly in which a externally threaded plunger (54) installed to a mirror body (3) is moved by a motor (102) to adjust the support angle of a mirror (4) secured to the mirror body. In addition to the drive system using the motor (102), another motor (103) is provided which operates independently of the motor (102) to quickly rotate the externally threaded plunger (52) forwardly and reversely. Thus, the mirror assembly according to the present invention is imparted the conventional function to adjust the mirror angle and a function to quickly tilt the mirror by means of the independent driving means. The above-mentioned independently driving means permits to quickly tilt down the mirror body for viewing the reflected image of the car rear wheel and also to quickly return the mirror body (3) to the initial position thereof.
