ABSTRACT:
There is provided a door locking handle assembly in which a bearing (6) is provided in a base member (3); a shaft (7) mounted in the bearing (6) is fixed to a handle (4); a lock lever (5) is fixed to the handle (4); a latch casing (18) is fixed to a front of the handle (4); a lock unit (23) is mounted in a lock-receiving portion of the handle (4); a receiving portion (32) engaged with and disengaged from a dead bolt (46) of a latch (27) in the casing (18) is formed in a front of the lever (5); and, stoppers 14 and 15 of opposite ends of the lever (5) are engaged with grooves 16 and 17, respectively; whereby a fear of overlooking an unlocked condition of the handle (4) is eliminated; and, since torque from the shaft (7) is dispersed and received through the stopper mechanism (14, 15, 16, 17), a fear of deforming the unit (23) is eliminated even if the assembly is subjected to such torque in its locked condition.
