Abstract
The latch comprises a mechanism for actuating at least one bolt comprising a door-knob hub adapted to receive an actuating rod for said mechanism. The latch further comprises an intermediate member which is rotatively mounted in the door-knob hub and ensures the rotatable mounting of the door-knob hub in the case of the latch. The intermediate member comprises an aperture for receiving the actuating rod and is provided with a nose portion for engagement with a branch of the door-knob hub in the course of the rotation of the actuating rod in the direction for actuating the latch. An abutment is provided for stopping the rotation of the nose portion after a given angular displacement of the actuating rod in the direction opposed to the direction for actuating the latch.
