Description

GERMAN

The invention relates to a bolt latch lock with a hook latch rotatably mounted in the housing, which unlocked by means of a key inserted in the pivot point of the latch or by means of a lever handle and from the The closed position is moved into the open position via an intermediate member.

A lock with a hook bolt is already known which is rotatably mounted in the housing and is rotated by means of a key or handle from the closed position into the open position via an intermediate member. Here, the hook bolt is moved into and out of the strike plate via a part that is displaceable parallel to the faceplate by a pin lying outside the pivot point of the hook bolt, which is actuated by the key or handle. * 5 Furthermore, a bolt latch lock with a hook latch is known, which is rotatably mounted in the housing and is moved from the closed position to the open position by means of a key inserted in the pivot point of the latch. In this previously published device, the hook latch is used at the same time to couple the bolt latch and the locking cap, the bolt latch being locked by a spring-loaded locking bolt that is guided parallel to the faceplate, which engages in the nose of the bolt when the bolt is in the locked position and by one of the bolt when the bolt is open Bar pleat controlled, spring-loaded locking slide is held out of engagement.

Opposite to the first-mentioned training, in the subject matter of the invention, the fulcrum of the actuating parts is located as well as the intermediate link and the locking slide centered on the pivot point of the hook latch. Of the Construction of the second-mentioned device points to the achievement of the aim sought by the invention more individual parts and has a bulky space requirement due to the off-center position of the locking bolt. In the deadbolt latch lock according to the invention is compared to the known as a result of the central Location of the actuating means and the locking bolt for the hook latch further reduces the size, which also reduces the purchase price and the cost of striking the lock.

The invention consists in that by turning the key in one direction when the latch is in the closed position, a locking bolt can be inserted radially into an opening in the rear wall of the lock case and, when rotating in the other direction, can be retracted into the circumference of the case, the locking bolt being U-shaped In the center plane of the lock disc encompasses and both parts, locking bolt and ~ 5 ° disc, within the nut carrying the door handle, the locking bolt is coupled to rotate with it, but is slidable in it, the disc is fixed in it.

In a further embodiment of the invention are the

Number of key bit levels arranged according to lock washers on both sides of the disc.

Due to the symmetrical design of the lock to the center plane, the lock is also suitable for right and left opening doors suitable.

Furthermore, one is for the latch compression spring in the back of the loop around the lock housing Adjustment screw arranged.

The disc located centrally in the nut still has stops on both sides and a fixed one Partition wall for the purpose of being able to move the trap with the key in addition to locking and a Prevent looking through the keyhole.

The subject of the invention is explained in more detail in the drawing, namely shows

The bolt latch lock with lifting cases consists of the lock case α (Fig. 1 to 5), which is composed of lock plate, loop, face plate and lock cover. For assembly as a box lock, the drill holes / and for assembly as a mortise lock, the drill holes f are provided. The lock cover is fixed by four pins d and fastened by the countersunk screws, in addition it is still

particularly held by the centering ring m. The latch guide, the threaded hole for the spring adjustment screw b (Fig. 1 and 3), and the opening for the locking bolt p (Fig. 1, 3, 5, (5 and 8)) are incorporated into the circumference. Fig. 1 to 6) Lies in the lock case a; it has a known circular shape within the guide recessed in the circumference and is kept under tension by the adjustable compression spring c (Fig. 1, 3 and 6) The locking bolt p. The nut h (Fig. 1, 3, 5 and 6) is inserted in the center of the hook latch.It is a hollow cylinder closed on one side with two openings for the locking bolt p; The inside of the nut h is located in the middle of the disk 0 and on both sides there are four or more safety disks r, which are designed according to the key bit steps. The disk 0 and theSafety washers r are held in place in nut h by round wedge q. The disk 0 has a partition in the middle, so that a special keyhole cover is unnecessary. The disko is encompassed on both sides by the two-armed locking bolt p made of spring steel (Figs. 1, 3, 5, 6 and 8). Due to the clam-like shape and the outward explosive action of the spring force, unintentional movement of the locking bolt p is prevented with certainty, so that special tumbler springs are unnecessary. The centering rings m secured with pins are screwed on both sides of the socket ends which protrude from the lock case and are provided with external threads. In addition, the threaded caps k (Fig. 6), which have round, externally thin and keyhole-guided approaches, can be screwed and pinned onto these socket ends for handle operation for attaching the handle / (Fig. 6). The handles also have fine bores to match the threaded cap approaches and have the keyhole guide on the outside. They are also fixed with a pen. The cover rosettes are marked with .s (Fig. 6). For security reasons, the nut should always be installed in the lock case in such a way that the screw cap of the nut is on the inside of the room to be locked and therefore it is impossible to dismantle the safety washers from the outside. When assembling the nut, the locking bolt is first pushed completely into the nut (Fig. 5) and after the lock has been assembled, the locking bolt is pushed back into its normal position. The operation of the bolt latch lock with rotating hook latch is described as follows: If you insert the key (Fig. 9) into the lock and turn it half a turn, the key bit, which moves within the stop cutout in the locking bolt p, becomes the locking bolt pushed outwards into the surrounding area, blocking the latch and the trigger. The lock is locked, the handles cannot be moved. When the key is turned in the opposite direction by half a turn, the key bit engages the upwardly directed hook-like projection of the locking bolt and pulls it back out of the surrounding area, so that the lock is unlocked and the handle can be moved. But if the lock is only operated by a key, the key is turned in the same direction so that the key bit comes to rest against the stop of the disk 0 and the nut and the latch connected to it by the locking bolt are moved by the pressure of the beard. The shape and mode of operation of the subject of the invention is solely due to the central locking of the nut, the new locking bolt and its washer 0. If the subject of the invention is used as a box lock, only the cover rosette is on the inside of the room and, if the key is only operated, on the outside the threaded cap k is omitted.
