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 ( ) is fixedly mounted on a rear surface of a housing ( ). A latch portion ( ) is formed in a receiving lever plate ( ) pivoted to the housing ( ). The solenoid ( ) has its plunger ( ) pivoted to the lever plate ( ) which is rotatably biased by a spring ( ) in the direction in which the lever plate ( ) is engaged with a stopper plate ( ). When the solenoid ( ) is energized, the lever plate ( ) is pulled back to have the latch portion ( ) disengaged from the stopper plate ( ).
