DE1002655B - Lock that can be removed from the parts to be locked - Google Patents

Description

The invention relates to a lock which can be removed from the parts to be locked and a on a locking bar od. The like. Slidable and lockable in any position lock body with lock cylinder having. Removable locks that can be taken with you when you travel and for Closing or additional closing of doors or the like are known per se. In the case of the parts that can be removed from the parts to be closed known locks is used as a locking device, a loose socket pin, optionally with a chain hangs on the lock housing and can be inserted locking into openings in the bolt.

Compared to the known removable. Locks, the invention consists in that the locking device between the lock body and ¹ bolt is formed by a U-shaped spring arranged in the lock body, the legs of which engage resiliently in cutouts of the bolt and can be spread by actuating a lock cylinder with the appropriate key and thus disengaged from the locking position . While the socket pins of the known removable locks offer no security against unauthorized opening, since they can easily be pulled out of the locked position by anyone, the unlocking of the new lock can only be done by turning the lock cylinder with the appropriate key, so only by an authorized person , take place. The new lock therefore offers extensive security against improper opening. With the U-shaped spring provided between the lock body and bolt as a feed organ, the legs of which engage in locking cutouts in the bolt and can be released by spreading, it also offers the further essential advantage of a particularly secure lock with a simple and compact design option for the lock housing and particularly lighter Handling like a normal cylinder lock.

The lock cylinder of the removable new one According to the invention, the lock has to expand and disengage the spring legs from the engaged position with the bolt a beard reaching between the spring legs, which is preferably in the form of a Toggle is formed.

The bolt and the spring are also expediently designed so that they form a ratchet lock, which ^ move the lock body into the desired locking position on the bolt like a ratchet and in every position automatically without using the appropriate one. Key to be blocked.

The drawing illustrates an exemplary embodiment of the new castle. It shows

Fig. 2 shows the complete lock according to Fig. 1 in longitudinal section,

Fig. 3 is a longitudinal section through the lock along line 3-3 of Fig. 2,

Fig. 4 shows a cross section through the lock along line 4-4 of Fig. 2,

Fig. 5 is a perspective view of the spring provided in the lock of Figs.

In the exemplary embodiment shown, a lock body 10 is adjustably arranged on a bolt 11. At the front end of the bolt 11, a hook 12 or the like is provided which engages in an opening or other engagement groove on a door frame A , as shown in FIG the door B and locking the lock the door is secured against opening.

In the lock body 10, a lock cylinder 13 for the matching key K is rotatably mounted at an angle to the bolt 11. A provided at the inner end of the lock cylinder 13 beard 14 is arranged near the bolt 11, while the key K is so far away from the bolt 11 in the inserted position with the protruding from the lock cylinder part that it is without interference by the Latch 11 can be operated easily. The angle of inclination of the lock cylinder 13 to the bolt 11 can be selected as desired and also be larger or smaller than in FIGS. 1 and 2.

The lock of the lock body 10 on the According to the invention, the latch is carried out by means of a spring 15. The spring 15 is U-shaped from a spring steel strip bent so that it forms two legs, the lower

edges of the top of the bolt 11 rest. The apex of the spring 15 is mounted on a retaining pin 16 provided in the lock body 10, so its apex surrounds the pin 16 in a recess 17 of the lock body 10. The two spring legs are provided with outwardly directed bends 18 at their ends, which end in teeth 19 that act like pawls. The teeth 19 protrude over the two longitudinal edges of the bolt 11, as can be seen in particular from FIG. 4. The U-shaped spring 15 is designed in such a way that the diverging teeth 19 at the ends of their two legs press normally against the longitudinal chambers of the bolt 11 and engage in the teeth 20 provided on the longitudinal edges of the bolt. The bolt teeth 20 are directed obliquely to the hook end 12 of the bolt 11 in such a way that the diverging pawl-like teeth 19 of the U-shaped spring slide ratchet-like over the bolt teeth when the lock body 10 is moved on the bolt 11 in the direction of its hook end 12, while the lock body 10 is normally locked against return movement on the bolt 11 in any position.

In the example drawn are both legs of the U-shaped spring with pawl-like teeth 19 and both longitudinal edges of the Bar 11 is provided with teeth 20. Of course, it is also sufficient to only provide a toothing on one locking cam.

The beard 14 at the inner end of the lock cylinder 13 is arranged between the legs, the U-shaped locking spring 15 or, as shown in the exemplary embodiment, between upwardly directed arms 21 of the spring legs. The beard preferably has an elongated shape that looks like a toggle. When the beard 14 is parallel to the spring legs, the teeth 19 engage the teeth 20 of the spring in the latch 11 and lock the lock body 10 in each. Position against backward movement outwards. If, however, the lock cylinder 13 is turned by actuation with the appropriate key K so that the beard is placed transversely between the legs of the U-shaped spring 15, the beard spreads the two legs of the spring 15 like a toggle so that their teeth 19 are decoupled from the teeth 20 of the bolt 11 and release the lock body 10 to move back on the bolt away from the hook 12 to the outside. In this position of the locking bit 14, the lock body 10 is freely movable in both directions on the bolt by disengaging the ratchet mechanism 19, 20.
