Description

Lock, the bolt of which is provided with key handles on both sides The invention relates to a lock, the bolt on both sides with Key attacks is provided whose tumblers are symmetrical and by setting their feathers in the range of one or the other key attack get, with the keyhole intended for a key attack on the bolt by a locking plate movably arranged on the inside of the lock plate is laid transversely when the lock is locked.

According to the invention, this locking plate, which is around the axis of the upper Key swings, equipped with a cutout and stands with the lock bolt in such an inevitable connection that this section is also in the open position of the lock is to the side of the keyhole and is with its edges held flush only when the lock bolt by means of the other key attack moving key was brought into an intermediate position. This is supposed to achieve be that only the owner of the lock has the key. able to decrease that But closed itself with the security that cannot be removed from it. security key can be closed forwards and backwards.

The lock is mainly used for such doors (apartment doors), those from outside with the usual removable key, but from the inside the door can be opened and closed with the strange security key should. It is known that the keyhole is used in security locks or double locks of the tenant's lock by one of a tumbler plate of the civil servant's lock Locking plate to be laid transversely when the lock is locked and open when the lock is open to keep. It is also known to have keyhole locking plates on the outside of the Lock to prevent the key from being pushed out. According to the However, the invention is intended for the locks in question by means of said locking plate for the keyhole that can be achieved regardless of the open or locked State of the lock the key belonging to this lock is held in the lock and will only be removed when the lock bolt is in an intermediate position can, which has the advantage that duplicate keys to the Inn: enschloßgesperre cannot be established.

In the drawings, the lock is shown in an exemplary embodiment, the known per se, under the action of feathers, on both key attacks acting tumblers are not shown.

Fig. I shows the inside of the lock in a view, Fig. 2 a vertical view Section through the lock, Fig.3 a view of the lock with the lock plate attached; Fig. A view of the inside of the lock with the one for inserting and removing the Security key suitable position of the individual parts. As known it is assumed that the bolt i on each of its sides with:, - in, z * key attack a, 3 is equipped, and that his pin .1 of the tumblers not shown is affected. The key attack 2 can only be introduced from the outside Key 5 (Fig. 4) are detected and the tumblers enter a such a position that in the locked position of the bolt i an effect on the key attack 3 is locked from the inside by means of a second key.

This second key should be used in normal positions of the locking mechanism; So both in the open and in: the locked position of the bolt i, off the lock cannot be removed. In order to achieve this characteristic of the castle, a pin z5 is arranged on the bolt i, dex in a slot 6 one in the lock rotatably mounted, two-armed locking arm 7 engages, the above Key bit * gripped like a hook. The hook flange 13 is with a cutout 8, but it partially covers the normal positions of R1, - -ge: ls i (both open and locked position) on the underside of the lock plate g. this in this intended keyhole i o for the key attack 3.

The fact that the locking plate 7 in positive connection with your Bolt i is on, it takes both the open and locked position of the bolt such a position that each part of the hook flange on the inside the lock plate g comes to stand in front of the beard of the key i i and this therefore can be pulled out of the lock at night. Should the keyhole be released the locking plate 7 is in the position shown in Fig. q. to bring the drawn situation, in which the cutout 8 faces the key height. To do this the bolt i must use the external key 5, which the owner in safekeeping holds, can be moved halfway (Fig. 1), and then the inner key can be used inserted into the lock or withdrawn from the lock.

In the illustrated embodiment, the end is the locking plate 7 bent like a hook, and the cutout 8 is in the hook flange 13, so. .that in the prescribed manner the security key i i in the lock held or with special adjustment of the bolt i by means of the. Exexi key can be pulled out of the lock.
