Abstract
Abstract The present invention relates to a vehicular rearview mirror, particularly a vehicular rearview mirror which can be electrically adjusted by a driver sitting in the driver's seat by pressing lightly a toggle switch with one hand, enabling the rearview mirror to shift its direction upward or downward, to the left or to the right and arrive at the most suitable reflection angle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
210 words
A universally adjustable mirror comprising a mirror, a support for mounting said mirror for universal movement with respect to a fixed member, a two directional D.C. motor, a shaft rotatable about its axis and movable longitudinally with respect to said axis, gear means for rotating said shaft in accordance with the direction of rotation of said two directional motor, a worm gear mounted on said shaft, a first transmission disc operatively connected to and rotatable by said worm gear when said motor rotates in one direction, a first linkage means connected to said first transmission disc for reciprocally turning said mirror about a first axis, a second transmission disc, a second linkage means connected to said second transmission disc for reciprocally turning said mirror about a second axis substantially perpendicular to the first axis, a driving gear mounted on said shaft for driving said second transmission disc said worm gear operating to move said shaft longitudinally upon rotation of said shaft by rotation of said motor in the opposite direction thereby causing disengagement of said worm gear from said first transmission disc, biasing means for normally urging said worm gear into engagement with said first transmission disc and means for controlling the direction of rotation of said two directional motor.
Claim 2
Dependent Claim
210 words
A universally adjustable mirror comprising a mirror, a support for mounting said mirror for universal movement with respect to a fixed member, a two directional D.C. motor, a shaft rotatable about its axis and movable longitudinally with respect to said axis, gear means for rotating said shaft in accordance with the direction of rotation of said two directional motor, a worm gear mounted on said shaft, a first transmission disc operatively connected to and rotatable by said worm gear when said motor rotates in one direction, a first linkage means connected to said first transmission disc for reciprocally turning said mirror about a first axis, a second transmission disc, a second linkage means connected to said second transmission disc for reciprocally turning said mirror about a second axis substantially perpendicular to the first axis, a driving gear mounted on said shaft for driving said second transmission disc said worm gear operating to move said shaft longitudinally upon rotation of said shaft by rotation of said motor in the opposite direction thereby causing disengagement of said worm gear from said first transmission disc, biasing means for normally urging said worm gear into engagement with said first transmission disc and means for controlling the direction of rotation of said two directional motor.
Claim 3
Dependent Claim
57 words
An adjustable mirror as claimed in claim 1 wherein said support for said mirror comprises a backing plate therefor, a ball-type joint connecting the center of said plate to a fixed member and wherein said first and second linkages are each connected to said plate at a point spaced vertically and laterally respectively of said ball-type joint.
