  • Patent number: 5343333
    Abstract: An electrically remote-controlled mirror assembly having a pair of plungers driven by first and second motors for tilting the mirror about the horizontal and vertical axes, respectively, and for quick-rear-viewing, there is provided a mirror driving mechanism by which the mirror can be tilted further through a predetermined angle beyond the predetermined range of angulation for the normal car moving to an angular position suitable for viewing the rear wheel of the car and thereafter returned to its initial predetermined angular position.

  • Patent number: 5274505
    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.

  • Patent number: 5226034
    Abstract: The electrically remote-controlled type mirror assembly has a pair of plungers to tilt the mirror body supporting the mirror horizontally and vertically, respectively, within certain pivoting angles. The mirror assembly has a sliding mechanism including another motor to axially slide at least one of these plungers beyond said certain pivoting angles of the mirror body. The sliding mechanism is so arranged as to have no influence on the adjustment of the mirror angle within the certain pivoting angles of the mirror body. Thus, the mirror posture can be changed quickly from the mirror angle adjusted within the certain pivoting angle for ordinary car driving to the mirror angle with which the mirror is tilted further downward, and also the initially adjusted mirror angle can be restored accurately.
