DE2400570C3 - Slide bolt for a lock, especially a mortise lock for a tubular frame door - Google Patents

Description

The invention relates to a sliding bolt for a lock, in particular a mortise lock for a tubular frame door, which can be excluded in two turns and one of the number of tours corresponding to the number of Closing engagement openings for the lock bit actuation is assigned.

In the known embodiment of the sliding bolt, it has two securely located one behind the other Closing engagement openings, see FR-PS 9 91 825. When the sliding bolt is closed, these engagement openings are located beyond the key opening, so that there is a relatively large lock housing depth results. Such a lock is therefore not suitable for tubular frame doors.

A smaller lock housing depth is, however, with a large slide bolt exclusion in another known Design before, US-PS 32 22 898. However, there is only a single-speed exclusion in which According to the gear drive, the locking parts move apart and it is imperative to use the furthest each time the lock is locked Generate bolt exclusion. The one at the closing front Aibeil to be applied is therefore always with one Turn the key. In addition, there are greater frictional losses from interlocking lock parts Since the telescopic seam joint of sliding bolt parts is outside the lock, there is also a larger one There is a risk of contamination

Rpim subject of the unpublished, older application from DT-OS 22 39 390 is a Rieeelfalle with a guided on a driver, Described spring-loaded slide, the rear tongue as an abutment of the locking bit when closing the pre-locked latch is used.

The object of the invention is to provide a generic sliding bolt door a lock in manufacturing technology simple and useful way to train so that the exclusion path for the second sliding bolt tour not as an enlarging lock case depth

^ This problem is solved by the features of the characterizing part of claim 1

The subclaims represent advantageous developments of the subject matter of claim 1.

As a result of such a configuration, a generic sliding bolt for a lock is created, which gives this a significantly improved burglar resistance and increased utility value. The fact that the locking engagement opening for the second tour is only formed after the first tour has been excluded results in the advantage that the slide bolt tail does not need to be extended from the outset by the amount of the second exclusion path, but a single-turn locking slide bolt in the longitudinal dimension is equivalent to. The surprising effect that, despite the single-turn longitudinal dimension of the sliding bolt, multi-speed closing with a large bolt exclusion is possible, results from the fact that the increased length of the sliding bolt necessary to achieve a greater exclusion males for the step-by-step engagement of the locking bit in the locking engagement openings is only for the second, excluded position is necessary. In addition to the advantages in terms of manufacturing technology, the low housing depth makes it possible for the first time to use a lock with a two-turn sliding bolt on tubular frame doors. In practice, this means that due to the possible, second sliding bolt exclusion, the known burglary method of prying the door and frame apart in order to bring the sliding bolt out of engagement with the counter-locking part can no longer be used. With regard to this burglary method, a considerable benefit is achieved. The operation of the sliding bolt in the lock is achieved through a simple structural design. All that is required is an additional slide, which can be displaced in the exclusion direction of the sliding bolt relative to the latter, in order to achieve the mode of operation described above. This slider can also used to deadbolt leads preferably in a guide channel of the sliding bolt, which on the one hand the co-operating parts constitute a compact unit and on the other hand, the usual distance between the top _i_jj _en jj _cs CQfjiQßtyehäiices be maintained. This also creates the advantageous possibility of excluding partial sections of the slide with the sliding bolt through the corresponding faceplate opening without enlarging the faceplate opening

lock bit 11 enters the locking engagement opening 10 of the bolt tail 7 '.

The thus unlocked sliding bolt 7 is shifted when turning the key in the direction of arrow χ by attack of the lock bit 11 on the locking engagement opening edge 10 'in the locking direction A until the lock bit out of engagement with the closing engagement opening edge 10' arrives. Due to the load on the compression spring 16, the slide 13 remains in its stop position on the stop 22 '"of the tumbler plate 22, which means that between the locking tongue 15 of the bolt tail T and the tongue 14 of the slide 13 there is another locking engagement opening 31 for the locking bit 11 to enter for the second exclusion tour This position is illustrated in FIG.

The key has meanwhile been turned further in the direction of the arrow χ , so that the locking bit 11 again steps against the tumbler plate 22, which has meanwhile been displaced back by spring loading, and lifts this again as illustrated in FIG.

The lock bit 11 now engages the locking tongue 15 of the bolt tail T and, when the key is turned further, causes the second exclusion tour of the sliding bolt 7 into the second exclusion position.

The tongue 14 of the slide 13 is used to achieve the in F i g. 4 illustrated bolt exclusion position is not required. The tongue 14 is only necessary for moving the sliding bolt back in the inward direction of the housing. Here, the locking bit 11 now rotates against the direction of the arrow χ against the tongue 14 and shifts the slide 13 together with the sliding bolt 7 against the locking direction A until the position corresponding to the first exclusion tour is reached and then acts when the key is turned further with the locking tongue 15 of the Latch tail T together until the closed latch position according to FIG. 1 is reached.
