<p>When the key (1) is pushed into the keyhole the lower segment (2) is folded at a joint (3). The lower segment (2) is guided through a specifically shaped space (7) at the lock during the folding process before reaching the position (8) required for engaging with the locking hoop (5). The hoop (5) is provided with a projection (9) acting in combination with the catch. The key (1) can now be turned in order to lock or unlock the unit. It can be withdrawn after a full turn back into the prior position.</p> |
