ABSTRACT:
A door locking handle assembly of a pull-out and side-swinging lever-action type includes a casing (1) having a locking shaft (11) and a handle (18) which can be swung out and pushed in a front concave portion (3) of the casing smoothly without fail. A push button (24) is pivoted to a front end of the handle (18) through a cross pivot (31), and has its intermediate portion (26) partially formed into a corrugated surface (28). A corrugated leaf spring (32) is fixed to a rear surface of the front end of the handle (18), so as to have its peak portion (32a) engage with a trough portion (28b) of the corrugated surface (28) of the push button (24) so that the push button (24) is held in a depressed position, whereby an engaging hook portion (29) of the push button (24) is held in its retracted position free from a receiving portion (5) of the casing (1 ).
