ABSTRACT:
A door locking handle assembly of a pull-out and side-swinging lever-action type, includes a casing (4) having a rotatable locking shaft (12) and a pivotable handle (19). When the handle (19) is pushed into a front concave portion (6) of the casing (4), the handle (19) can be held in its retracted position without fail. A push button (27) is pivotally mounted on a front-end portion of the handle (19) so that when the push button (27) is swingably depressed, the handle (19) can project outwardly from the front concave portion (6) of the casing (4). The thus projected handle (19) is side-swing to have a catch plate (11) of a locking shaft (12) disengaged from its locking position. In the assembly, a lock unit (31) is fixedly embedded in a front-end portion of the handle (19); a lock plate (33) interlocked with a rotor (32) of the lock unit (31) is provided; and the handle ( 19) is pushed into the casing (4) in a condition in which a lock plate (33) abuts on a leg portion (28) of the push button (27) to prevent the button from swinging inwardly.
