Engaging mechanism of closing device

摘要

An engaging mechanism of a closing device includes an engaging block, a positioning hook and a pin. The engaging block has a contact surface and a guide surface extending from the contact surface. The positioning hook is connected to the engaging block and has a resilient portion and a stop which extends from the resilient portion. The stop is located adjacent to the contact surface and located at a distance from the guide surface. The pin is located corresponding to the engaging block and slidably contacts the contact surface and the stop of the positioning hook. The pin moves over the stop and is disengaged from the contact surface by contacting against the stop and the deformation of the resilient portion.

1. An engaging mechanism of a closing device, said engaging mechanism comprising:
a contact member having a first recess and a second recess formed therein, said first recess formed in a first section of said contact member, said second recess formed in a second section of said contact member, and an engaging block mounted to said contact member defining a guide path for a pin secured to a sliding rail; a resilient positioning hook connected to the engaging block and having a stop member; and upon displacement of said pin in a first direction in said first section, said pin being biased in said first recess to displace to an inclined surface of said engaging block to bear against said stop member; wherein when said pin is displaced further in said first direction, the pin is displaced into said second recess, said pin being biased in said second recess into said second section for removal of the pin from said guide path, and when said pin is displaced in a second direction, said stop member is displaced to allow said pin to enter said second section of said guide path for removal of said pin from said guide path.
