Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To improve amenity and operationability at the time of closing a door. SOLUTION: The door lock device has a handle 1, a shaft 2, a pawl 3 engaged with a pin 102 for a main body section, an end-section shaft 4, a spring 5, a projecting shaft 6, a pin 7 for the projecting shaft 6, etc. Lock sections 3a, 3b at two stages are installed to the pawl 3. The pin 7 is urged to one side by the spring 5, and the reverse side in a groove 4a is formed in structure, in which the reverse side is opened. The pawl 3 and the end-section shaft 4 are urged in the clockwise direction by a spring 9, and operated integrally. Consequently, when the handle is depressed, one-stage lock is applied first. A clearance is formed between a door and the main body at that time, and internal pressure is let to escape. Reaction at a time when the pawl 3 collides with the pin 102 is buffered by the spring 5, and transmitted to a hand.  Since internal pressure is let to escape, two-stage lock is applied easily. Accordingly, strong closing force is unnecessitated while buffer action is generated, and operation at the time of door closing is made comfortable and facilitated.
