Remotely controlled mirrors
First Claim
1. A remotely controlled mirror comprising a stationary base plate contained in a mirror housing;
- a back plate provided at the back of a mirror and provided with a supporting mechanism that can tilt in any direction with respect to said base plate;
a pair of threaded rods with one ends rotatably and tiltably connected to said base plate;
spring means with one end thereof being supported by said base plate and engaging with the threads of said threaded rods while the other end being free, thereby controlling axial movements thereof;
means for limiting the axial movement of the spring means that is caused by the rotation of the threaded rods engaging with the spring member;
a pair of worm wheels respectively having openings for receiving the other ends of said threaded rods;
a pair of worms meshing said worm wheels respectively; and
a source of drive for selectively rotating said worms;
the openings of said worm wheels and the other ends of said threaded rods being constructed such that it is possible to transmit a torque there between but absorb stresses caused by the inclination of said mirror and acting between said worms and said worm wheels, and said threaded rods being rotated and moved in the axial direction with respect to said spring means by the torque applied thereto from said source of drive through said worm wheels.

Abstract
A back plate carrying a mirror is mounted on a stationary base plate through a universal support to be rotatable and filtable. Two threaded rods are connected to the back plate through couplings that rotate and tilt the back plate. The threaded rods each have ends connected to worm wheels respectively which mesh worms driven by one or two reversible direct current motors. A spring having a single turn at the center is used. The single turn portion is secured to the base plate and the opposite legs are urged against the threaded rods act as nuts so as to move the threaded in the axial direction when they are rotated where two worms are driven by a single reversible direct current motor, the worms disposed on the opposite sides of the motor and selectively connected thereto through clutches which are controlled by a solenoid.

7. A remotely controlled mirror comprising a stationary base plate contained in a mirror housing;
- a back plate provided at the back of a mirror and provided with a supporting mechanism that can tilt in any direction with respect to said base plate;
a pair of threaded rods extending along the axes of rectangular coordinates having an origin at said supporting nechanism, one ends of said threaded rods being tiltably supported by said base plate;
a spring member having a central portion fixed to said base plate and a pair of legs adapted to engage the threads of said threaded rods for applying spring force thereto so as to control the axial movement of said threaded rods when they are rotated;
means for limiting the axial movement of the spring means that is caused by the rotation of the threaded rods engaging with the spring member;
two worm wheels respectively having openings to receive the other ends of said threaded rods;
worms respectively meshing said worm wheels, and a source of drive for selectively driving said worms, the openings of said worm wheels and said other ends of said threaded rods being shaped such that torques can be transmitted therebetween but can prevent creation of stress between said worm wheels and said other ends of said threaded rods when said mirror is inclined so that said threaded rods one rotated and moved in the axial direction by the rotation of said worm wheels. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
