  • Patent number: 6490896
    Abstract: In a door lock handle assembly of pull-out and side-swinging lever-action type, an operating handle is released from its retracted position without fail upon receipt of an unlocking signal issued from a site remote from the handle assembly, and is automatically locked again to the retracted position when pushed back into the retracted position. A solenoid (12) is fixedly mounted on a rear surface of a housing (2). A latch portion (7) is formed in a receiving lever plate (13) pivoted to the housing (2). The solenoid (12) has its plunger (14) pivoted to the lever plate (13) which is rotatably biased by a spring (15) in the direction in which the lever plate (13) is engaged with a stopper plate (8). When the solenoid (12) is energized, the lever plate (13) is pulled back to have the latch portion (7) disengaged from the stopper plate (8).

  • Publication number: 20020124608
    Abstract: Although a door locking handle assembly is small as a whole in thickness, it permits through a computerized personal management system of users a plurality of persons or users to have access to instruments contained in a box provided with the door locking handle assembly in an easy manner. In the assembly, a combination lock (19) opened by turning each of a set of its specially marked dial discs (21) a given number of times to establish a unique combination of marks of the dial discs (21) is incorporated in a door handle (13) or a base body (1) of the assembly. In operation, a locking member (44) of the assembly prevents the door handle (13) from being pulled out of the base body (1), and is driven to reach its unlocked position when the combination lock (19) is opened.
