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 keeping a sufficient effective length of a handle 18 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 cross pivot 37, and swingably urged by a spring 38 to project outwardly. A button casing 24 is fixed to the concave 3. A push button 30 is slidably mounted in a recess 27 of the casing in an insertion manner while horizontally non-slidable therein and urged by a spring 40 to move upward, and has its upper projection 32 engaged with a front hook 20 of the handle 18. A rotor 42 of a lock unit 41 fixedly embedded in the handle 18 is engaged with a lock plate 45 engaging with a projection 26 of the button casing 24 to lock the handle 18 in its retracted position in the casing.
