ABSTRACT:
A door locking handle assembly of 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 obtained sufficiently to improve the assembly in operability. A catch plate 36 is fixed to a locking shaft 11 mounted in a cylindrical portion 2 of the casing 1. The handle 18 received in a front concave 3 of the casing 1 is pivoted to the shaft 11 through a first pivot 37, and swingably urged by a spring 38 to project outwardly. In the front concave portion 3 of the casing 1, a push button 30 is pivoted to a button casing 24 through a second pivot 39, and urged by a position-keeping spring 40 to have its engaging-hook portion 31 engaged with an engaging projection 25 of the button casing 24. A rotor 42 of a lock unit 41 fixedly embedded in the handle 18 is interlocked with a lock plate 45 engaging with an engaging projection 26 of the button casing 24.
