The invention relates to a lock with a shooting trap, in which the trap means The lever handle is pushed out or in from the first closed position and by means of a locking bolt, which occurs behind the trap in the second closed position, is blocked can be. The invention differs from known locks of this type by how the first closed position

ίο is secured, and also by the fact that the Blocking of the second closed position by the locking bolt under the action of a spring occurs automatically, as well as the trap by turning the trigger upwards into the second Brought closed position and thereby released the locking bolt that had been retained by her until then is. The lock is released by means of a key that holds the locking bolt pulls back, whereupon the latch returns to the first closing position by spring action

ment is returned. A very special advantage of the invention can be seen in that the locking of the second closed position automatically when the trap is inserted into it takes place as this is of utmost importance in warding off unauthorized intruders into apartments Meaning can be.

One embodiment is through

Fig. Ι in the view with in the first closed position trap and through

Fig. 2 in the view with the latch in the second locked closed position shown.

The in for the invention insignificant manner in the lock housing ι out shooting trap 2 can be moved by the pusher 6, which engages in the nut 4 with its lever attachment S, both to the right and to the left, depending on whether you or the pusher turns upwards. The central position of the trap which corresponds to the first closed position by the two by the pin 9 held in their inner end positions springs 8.8, which act in opposite directions ^a 5 senses to each other and the base of the tail 7 of the nut 4 summarize between itself and it always Strive to return to the central position, secured. In its first closed position (Fig. 1) and of course also in its right end position, the latch 2 holds the locking bolt 10, which is displaceable transversely to the latch and is under the action of the spring 11, but releases it as it is by turning the trigger 6 upwards second closed position corresponding to the left end position is brought. The locking bolt then snaps behind the latch and locks it (Fig. 2).
