<p>The lock has a drive shaft (7), which is moveable along a sleeve (1) to operate a stop bolt of an additional lock (8), with a co-operating frame-side stop pivot stirrup (57). By back-closing the main bolt (6) from a first pre-closed position, the stop bolt of the additional lock moves out into a stop pivot stirrup catchment position and after a second forward and backward closure operation of the main lock is fully moved backwards into the additional lock. A force accumulator engages on the stop bolt, and is charged up to a dead point position with each main bolt forward-closure operation. When the dead point position is exceeded the stop bolt is moved into its end position. The drive shaft works in conjunction with the stop bolt via an open slide guide, which curve-controls the stop bolt until above the dead point position of the force accumulator.</p> |
