<p>The lock for locking of doors and gates has locking bolt moved into open and closed position. This bolt is operated by two closing mechanisms connected with a lever system so that the lock bolt is moved by actuation of one of the two locking mechanisms. The lock system is designed so that the lock bolt in locking position cannot be pushed into open position by external force. The lever arrangement has a lever (3) connected to the locking bolt (2). The locking mechanism engages with this lever and the lever is connected to a blocking mechanism (58). This ensures that the bolt is firmly held in its locking position and the lock bolt can be moved by the rotation of the lever (3) by one of the lock mechanisms, into a released position before the lever (3) moves the lock bolt.</p> |
