Title: Ready-to-mount secondary locking device for a door equipped with a lock
IPC: E05B63/00
Filed: 1988-11-07
Abstract: The secondary locking device is actuated by moving the bolt 3 of the lock 2 of the door 1. It comprises a rod 9 forming a rocker arm composed of a hollow central element 13 and of two elements 8, 15 sliding in the central element 13. The top element 8 is bent and ends in a pivot pin 10 secured to the lateral part of the frame of the door above the lock 2. The bottom element 15 ends in a right angle 18.
