ABSTRACT:
A handle device for a door which is formed of an assembly installed in a door panel and has a handle grip connected thereto by a pivot pin. A latch is retractably mounted to the assembly and is interlocked with the handle grip. An actuating lever is pushed by the handle grip to move the latch. A reset lever drives the actuating lever when pushed by a push rod extending inside the door. A lock mounted on the assembly has a cam secured to a rotor, serves to release the engagement between a lock plate which is secured to the assembly and adapted to check the slide of the latch, and the latch. When the push rod turns the reset lever, engagement between the lock plate and the latch is released and the latch slides and is retracted by turning the actuating lever.
