ABSTRACT:
A door locking handle assembly of a pull-out and side-swinging lever-action type, in which the entire length of a casing (1) is minimized while an effective length of a handle (18) is sufficiently obtained to improve the assembly in operability. A catch plate (50) is fixed to a locking shaft (11) mounted in a cylindrical portion (2) of the casing (1). The handle (18) is received in a front concave portion (3) of the casing (1) and is pivoted to the shaft (11) through a cross pivot (40). A latch element (25) engaged with and disengaged from a hook (19) of the handle (18) is received in a latch casing (29). The element (25) is interlocked with a push button (37) in a depressing operation thereof to linearly move so that the handle (18) locked up in the casing (1) is released to project from the casing (1) by a biasing spring (41). A lock plate ( 48) is interlocked with a rotor (45) of a lock unit (44) fixed to the handle (18) so that the lock plate (48) is engaged with and disengaged from a hook (30) of the latch casing (29).
