An electrically foldable door mirror comprising a base, a shaft erected on said base, a mirror body rotatably attached to said shaft, electric driving means for turning said mirror body, a pinion secured to the output shaft of said electric driving means, said pinion being engaged with a clutch gear attached to the upper portion of said shaft, means for automatically stopping said electric driving means, said stopping means being disposed between one surface of a fixed clutch fixed to the upper end of said shaft and a surface of said mirror body opposing said one surface of the fixed clutch, said stopping means comprising a printed circuit and contact pieces slidable thereon. The mirror body in the erected neutral position can be turned backward by actuating the electric driving means. When the mirror body has come to the position of the rear turning limit, the electric driving means is automatically stopped by the stopping means. The mirror body in the position of the rear turning limit can be returned to the erected neutral position by reversing the electric driving means. When the mirror body has come to the erected neutral position, the electric driving means is automatically stopped by the stopping means.

Electrically foldable door mirror

An electrically foldable door mirror comprising a base, a shaft erected on said base, a mirror body rotatably attached to said shaft, electric driving means supported by a frame within said mirror body, a pinion secured to the output shaft of said electric driving means, said pinion being engaged with a clutch gear attached to the upper portion of said shaft, an upper clutch disposed between the upper surface of said clutch gear and the upper end of said shaft, a lower clutch disposed between the lower surface of said frame at the position of insertion of said shaft and the opposing surface of said base, a coiled spring provided around said shaft so as to give a force of engagement to both of said clutches, said upper clutch being more strongly engaged than said lower clutch so that said lower clutch is disengaged earlier when said mirror body is turned. The door mirror of the invention can be folded forward or backward both by remote control from inside the motor vehicle and by manual operation. The door mirror is smoothly folded also when it receives an external shock.

An electric device for adjusting the angle of reflection of a mirror mounted on a motor vehicle. The mirror is pivotally connected to an actuator unit housing containing two actuators. Two adjusting nuts each having a movable pivot are respectively moved forward or backward by their actuators so as to adjust the angle of the mirror. The device of the invention is characterized by having a first guide means and/or a second guide means for controlling the direction of inclination, horizontal or vertical, of the mirror so as to prevent the mirror from being obliquely displaced during the operation of the motor vehicle. The first guide means comprises a cross-shaped member provided in front of the actuator unit housing and a cross-shaped groove, engaging therewith, provided on a mirror holder. Alternatively, the first guide means may comprise a cross pin, one of the two axes thereof being supported on the actuator unit housing, the other axis thereof being supported on the mirror holder. The second guide means comprises openings, longer in the horizontal or vertical direction, into which the adjusting nuts are respectively inserted.

Electric mirror angle adjusting device with pivoting cross-shaped member

An electric device for adjusting the angle of reflection of a mirror mounted on a motor vehicle. The mirror is pivotally connected to a housing containing a reversible motor and driving mechanism. One end each of a pair of adjusting members is attached to the back side of the mirror pivotally and unrotatably. The adjusting members may be adapted to swing conically on their roots. Each adjusting member is provided with a worm wheel which, in turn, is in meshing contact with a worm gear. The worm gears are mounted on an axially slidable slide shaft or slide cylinder which is connected with the output shaft of the reversible motor. The slide shaft or slide cylinder is adapted to transmit the driving force of the reversible motor selectively to either of the worm gears. Thus, the driving force of the reversible motor is transmitted selectively through either of the worm gears and its respective worm wheel to either of the adjusting members which is now axially moved thereby and pushes or pulls the mirror.
