ABSTRACT:
The lock is formed from a fork which engages a striker pin and is itself engaged at one end by a catch; its main characteristic is that between the fork and catch there is interposed a rotatable insert which pivots at one end against the catch and is arranged to cooperate at its other end with the hook-shaped end of the fork, the insert being dragged rigidly with the catch by a spring connected to the insert eccentric to the position in which this latter pivots against the catch.
