Abstract:
1. A closure comprising: a pull-turn bolt or swiveling bolt for mounting in thin walls, the bolt having a tolerance compensating device with a back-engaging device located at a free end of the bolt; said bolt having a bore hole near its free end in which the back-engaging device is held so as to be displaceable perpendicular to a back-engagement plane of a back-engagement surface of a frame; said back-engaging device having a spring which forces a contacting portion of the back-engaging device in a direction towards the back-engagement surface of the frame when the closure is in the closed position, so that the contacting portion of the back-engaging device contacts the back-engagement surface of the frame; said back-engaging device adapting to varying distances between the free end of the bolt and the back-engagement surface of a frame by expansion and compression of the spring during use, so as to maintain contact with the back-engagement surface of the frame without need for manual adjustment of the back-engaging device; and said closure having a housing which holds said pull-turn bolt so as to be axially displaceable and rotatable or said closure having a housing which supports said swiveling bolt.
