Patent number: 6490896Abstract: 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).Type: GrantFiled: March 13, 2002Date of Patent: December 10, 2002Assignee: Takigen Manufacturing Co., Ltd.Inventor: Shirou Segawa
