Definitions
- the invention relates to a protective device for a mortise lock with a lock cylinder, with a tamper-proof outer cover, which encloses the end of the lock cylinder protruding on the outside of the door.
- a protective device with a break-proof rosette has become known from DE-C-31 05 208 by the applicant.
- a threaded cylinder is rigidly connected to a thin sheet metal plate independent of the lock case.
- the rosette has a continuous recess adapted to the cross section of the cylinder lock housing and is screwed onto the threaded cylinder mentioned.
- a mounting device with a screwed-on rosette is also known from US-A-3, 815, 390. With this assembly device, however, the rosette can be unscrewed by force. However, a screw-on rosette is not always desirable.
- the invention has for its object to provide a protective device of the type mentioned, in which the rosette is not screwed on and which nevertheless has a high safety value.
- the object is achieved in a generic protective device in that the outer cover is pushed onto a sliding plate which is connected to at least one holding plate which is designed such that it forms a drill protection for the mortise lock.
- the protective device according to the invention is suitable both for a wooden door and for a metal door with an alarm lock.
- the connection of the sliding plate with the holding plate is preferably done by screwing and results in a secure anchoring of the sliding plate and the cover. Stalling is therefore no more possible than with the assembly device according to DE-B-31 05 201 mentioned above.
- the preferably solid holding plate forms an effective protection against drilling and secure anchoring for the sliding plate. This drilling protection prevents tumblers from being lifted through a hole and the bolt being pushed backwards without actuating the locking cylinder.
- the holding plate is solid and made of, for example, hardened steel. This holding plate is preferably designed so that it covers the critical area of the mortise lock and is much larger than the rosette. This area is located above the locking cylinder.
- the cover is a slide and this slide has a rotatable disc with a slot. This disc covers the locking cylinder and effectively prevents the cylinder core from being pulled out.
- FIG. 1 shows a horizontal partial section through a wooden door with an attached protective device
- FIG. 2 shows a view of a cover
- FIG. 3 shows a view of a sliding plate
- FIG. 4 shows a view of a holding plate
- FIG. 5 shows a view of a further holding plate
- FIG. 6 shows a horizontal partial section through a metal door and a frame and a protective device according to a variant
- FIG. 7 shows a view of the outer rosette according to FIG. 6.
- FIG. 1 shows a conventional wooden door 2 with a recess 3, into which a conventional mortise lock 1 is inserted.
- a holder plate 9 is also inserted into the recess 3, onto which the further holder plate 8 shown in FIG. 4 is screwed.
- the holding plate 8 engages in an opening 18 in the door 2.
- a sliding plate 7 is attached to the outside 2a of the door 2 and is firmly connected to the holding plate 8 with fastening screws 12 (FIG. 7).
- An outer cover 6 designed as a slide is pushed onto the cross section T-shaped sliding plate 7, which completely covers the sliding plate 7 on the front and side.
- the parts 6, 7, 8 and the holding plate 9 each have a recess 13, 14, 15 and 16, respectively, which correspond to the cross-sectional profile of the shooting cylinder 4.
- the locking cylinder 4 has a so-called Hahn profile.
- other profiles for example a so-called Swiss profile, are also possible.
- the recesses 14 and 15 are provided with lateral extensions 14a and 15a, which enables a locking cylinder 4 with laterally projecting locking pins, not shown here.
- the holding plate 9 To attach the holding plate 9 to the back of the holding plate 8, this is provided with four threaded holes 21. Correspondingly, the holding plate 9 has four through bores 22.
- the holding plate 9 When mounting, the holding plate 9 is inserted with the screwed-on holding plate 8 through the recess 3.
- the mortise lock 1 is then inserted into the recess 3 and lies against the holding plate 9.
- the rosette 7 is screwed onto the holding plate 8.
- the locking cylinder 4 in FIG. 1 is pushed from the right through the cover 6 and the holding plate 8 into the mortise lock 1 until it no longer protrudes from the front.
- the cover 6 is pushed onto the sliding plates 7 and the locking cylinder 4 is moved into the position shown in FIG. 1.
- the cover 6 is now locked by the locking cylinder 4 and can no longer be removed from the sliding plate 7.
- the locking cylinder 4 is fixed in a known manner by a forend screw, not shown here.
- the door 2 is a metal door which is mounted on a frame 5.
- the protective device here consists of a holding plate 8, a sliding plate 7 arranged on the front of the door 2 and a cover 6.
- the holding plate 9 provided in the upper embodiment is therefore missing here.
- the sliding plate 7 and the holding plate 8 are screwed together as explained above.
- the mortise lock 1 is a so-called block lock, which blocks the door in the event of an alarm.
