ABSTRACT:
A door locking handle assembly of a pull-out and side-swinging lever-action type, includes a casing (4) having a locking shaft (12) pivotally attached to a handle (19), which can be pushed into a casing (4), and locked in its retracted position without fail. A push button (27) is pivoted to a front-end portion of the handle (19) through a pivot (25) passing through an axial hole (50) of the button (27). The hole (50) is obliquely extended and assumes an oval shape. By depressing the pivoted push button (27), the handle (19) swings out of a front concave portion (6) of the casing (4). A catch plate (11) attached to the locking shaft (12) is swingably moved to its unlocking position by side-swinging the handle (19), which has its front-end portion receive a lock unit (31) fixedly in an embedding manner. A lock plate (33), which is interlocked with a rotor (32) of the lock unit (31) so as to move back and forth, is brought into contact with a leg portion (28) of the push button (27) to prevent the push button (27) from rotating inwardly.
