Abstract

The system has a self-locking door lock provided with a trigger element that is automatically actuated for locking a door leaf (2) by a closing operation of the door leaf. The door lock is arranged in a door frame (1) having an electromagnetic door opener for opening of the self-locking door lock, where the lock includes a latching bolt. A transmission element is connected with the trigger element, where the trigger element is acted upon a two-armed lever, and the latching bolt is released by the transmission element actuated by moving a locking lever into a closed position.

Description

The present invention relates to a strike plate having a base body, which has in a first main plane latch cutout for a locking element or a trap cutout for a trap.

Such strike plates are well known in the art. These striking plates have a locking cutout in which a locking element of an opposite lock can engage. The triggering of a latch retraction is done manually via the operation of a key in a lock cylinder. Activating a latch retraction with a lock without a key and lock cylinder is not possible with such a strike plate.

The object of the present invention is therefore to further develop a strike plate of the type mentioned in that a bolt retraction can be activated with a lock without lock cylinder or technically less complicated.

The object is achieved in that in addition A Aulöseplattenausschnitt is formed for a release plate on which a triggering device is mounted, which cooperates in a door opening with the engaging in the Ausloesplattenausschnitt-release plate.

The object is achieved by the method according to claim 20.

With the present invention, it is possible to use the strike plate according to the invention with a lock having a separate trigger plate with which a door opening or a withdrawal of a door bolt is triggered. The striking plate according to the invention can thus be used for locking systems in which door openings are made without key and lock cylinder.

Another advantage of the present invention is that the invention has a trigger stop which extends in the longitudinal direction of the base body. The trigger stop can be adapted in this way over the entire width of a geometric design of the locking plate.

A further advantage of the present invention is also that the triggering device is adjustable transversely to the longitudinal direction of the base body. Due to the adjustability of the triggering device transversely to the longitudinal direction of the base body, a variable alignment alignment can be made to the level of the lock used in the locking system. In addition, can be brought about by the adjustability and an alignment with an electromagnetic door opener, if such is used. The adjustability compensates for dimensional tolerances and tolerates design-related differences.

Alternatively, it may be advantageous if not the entire triggering device, but only the trigger stop is adjustable transversely or parallel to the longitudinal direction of the base body.

Another advantage of the present invention is that the triggering device has a displacement plate for a stepwise adjustment of the triggering device, which is aligned transversely to the longitudinal direction. In this way, the flight adjustment can be performed not only variable, but also stepwise either to the level of the castle or in relation to the electromagnetic door opener. It has been found that steps of ≤ 1 mm are suitable for escape tuning.

Another advantage of the present invention is that the adjustment plate has on its underside a Verstellplattenzahnung in the longitudinal direction, which engages in a toothing of the base body. By means of the mutual toothing of the adjusting plate and the base body, an ideal stepwise adjustment of the triggering device relative to the base body can be achieved.

Another advantage of the present invention is that the main body has a trap cutout. The latch cutout is used to hold a door latch in lock systems without electromagnetic door opener and to receive a door latch when such a door opener is used.

A further advantage of the present invention is that the release plate cutout is arranged in the longitudinal direction of the base body between the trap cutout and the latch cutout. It has been found that the arrangement of the trigger plate cutout for receiving the door opening or door closure activating trigger plate between the latch cutout and the latch cutout with respect to the mechanical design of a locking system is particularly favorable.

Another advantage of the present invention is that the main body has a longitudinal edge on which a first incision and a second incision are formed at a distance from each other, wherein the latch cutout and the Auslöstesplattenausschnitt are arranged in the longitudinal direction between the first incision and the second incision. The cuts in the said area make it possible to form an angle sheet from the flat base body. This is favorable for the installation of the striking plate in a door frame.

Another advantage of the present invention is that the base body is connected to a surface piece that is connected between the first incision and the second incision with the longitudinal edge and extends in a second main plane. In the event that the sheet is to extend in a second direction, the respective cuts serve as a boundary.

For the installation of the striking plate in a door frame, it is favorable that the surface piece extends perpendicular to the base body.

Another advantage of the present invention is that the sheet is integrally connected to the main body. In this way, the production of the base body and the surface piece in a single operation is possible.

Another advantage of the present invention is that the sheet forms a lateral boundary for an electromagnetic door opener. For the use of an electromagnetic door opener, it is advantageous that it can be connected at a predetermined location fixed to the strike plate. The sheet serves as a side cover for the electromagnetic door opener. This increases the mechanical strength of a strike plate and door opener unit.

This leads to a compact design with high mechanical strength of the unit strike plate and door openers

Another advantage of the present invention is that the first incision and the second incision each form a recess on the longitudinal edge. The removal of material at the two incisions improves the bending of the sheet along a bending line.

Another advantage of the present invention is that the patch is folded between the first cut and the second cut. Due to the bendability, it is possible to adapt the patch locally to individual dimensions. Thus, due to the recesses in the cuts, a bending line between the base body and the surface piece run parallel to the longitudinal edge, do not run parallel to the longitudinal edge, or coincide with the longitudinal edge.

An advantage of the inventive method for attaching a striking plate with the features of one of claims 1 to 17 is that in addition to providing a strike plate and attaching the strike plate with respect to a cuff plate also adjusting the triggering device with respect to a for the cuff plate protruding latch plate is provided. As a result, the activation of the bolt retraction can be optimally adjusted.

Another advantage of the present invention is that the method includes, prior to attaching the striker plate, bending a sheet along a bend line depending on the dimensions of an electromagnetic door opener and / or depending on the dimensions of a mounting location.

In Fig. 1 is shown schematically a plan view of a striking plate 1 in a first embodiment according to the present invention. In the described embodiment, the striking plate 1 is intended to be installed in a door frame. The installation should be done in such a way that except in Fig. 1 shown "visible surface" after installation no other components of the striker plate 1 are visible. This is especially true for the in Fig. 6 illustrated embodiment.

The description of the embodiment with respect to the use of the strike plate on a door is chosen purely by way of example. Such a strike plate can also be used in conjunction with locks on other components that form an opening in a wall or wall and interact with a closing such an opening component. The term "door" is used below and also in the claims as a synonym for other locations, such as windows. The reference to a door does not hereafter limit the subject matter of the present invention to use in doors.

The striking plate 1 has in the present embodiment, a base body 2 with a quadrangular geometry with a first longitudinal edge 3, a second longitudinal edge 3 ', a first transverse edge 5 and a second transverse edge 5 '. In other embodiments, the main body 2 of the striking plate 1 or the striking plate 1 may also have a different geometry. So it is common to use in addition to square striking plates 1 and rounded striking plates. In such rounded striking plates, the transition from one longitudinal edge 3 to the other longitudinal edge 3 'follows a circular arc.

The transverse edges 5, 5 'determine the width of the main body 2 or of the striking plate 1. This is matched to the dimension of the installation object.

The main body has in the vicinity of the transverse edges 5, 5 'in each case at least one through hole 7. In the present embodiment, two through-holes 7 are respectively provided in the vicinity of one of the transverse edges 5, 5 '. The through holes 7 serve to receive fastening screws (not shown) in order to firmly attach the striking plate 1 to a door frame (not shown). The through-holes 7 are arranged offset in the vicinity of the respective transverse edges 5, 5 'in order to establish a connection with the door frame with higher force-fit.

In the Fig. 1 In the illustrated embodiment, a latch cutout 9 for a door latch and a latch cutout 11 for a latch (a lock) and a release plate cutout 13 for a release plate of a lock are formed in the main plane H1. For the present invention, the presence of a trap and a trap section 9 is not mandatory. For this reason, closing plates 1 are claimed in embodiments expressively, which have no latch cutout 9. For the present invention, the presence of a bolt and a latch cutout 11 is not mandatory. For this reason, locking plates 1 are claimed in embodiments that have no latch cutout 11.

In the vicinity of the latch cutout 11 and in the present embodiment between the latch cutout 9 and the latch cutout 11, approximately in the longitudinal center of the base body 2, a trigger plate cutout 13 is formed. The trigger plate cutout 13 is for receiving a trigger plate 15 (FIG. Fig. 3, Fig. 5 ) intended. The release plate 15 is a component of the lock and therefore not the subject of the present invention. For an automatic release of a bolt retraction from the bolt cutout 11, the latch plate 15 but is important. For this reason, the strike plate 1 is arranged in a door frame so that the

Trigger plate cutout 13 is aligned with respect to a cuff plate 16 and the latch plate 15, so that they can engage in the closing plate cutout 13 when closing a door.

On the trigger plate cutout 13, a triggering device 17 is attached. The triggering device 17 is adjustable transversely to a longitudinal direction of the base body 2 in the present embodiment. In other embodiments, an adjustability in one other direction or by pivoting the trigger stop 17.2 or the triggering device 17 are brought about. The longitudinal direction of the main body 2 is the direction which extends parallel to the longitudinal edges 3, 3 '. The adjustability of the triggering device 17 thus takes place substantially parallel to the transverse edges 5, 5 '. The triggering device 17 comprises in the present embodiment, an adjustment plate 17.1 and a trigger stop 17.2. In the adjusting plate 17.1 a slot 17.3 is formed, which is aligned with a threaded bore in the base body 2, so that by means of an actuating screw 17.4 an adjustment of the trigger stop 17.2 in the latch plate cutout 13 is possible.

In other embodiments, a construction may be selected in which the trigger stop 17.2 itself is slidably mounted independently of an adjustment plate.

In Fig. 2 It can be seen that the triggering device 17 is mounted on the main surface H1 of the main body 2. In other embodiments, the triggering device 17 may also be inserted into the base body 2, so that the upper side of the triggering device 17 is aligned with the main surface H1.

In the FIGS. 6, 7, 8, 9 and 10 a second embodiment of the striker plate 1 according to the present invention is shown. The second embodiment differs from the first embodiment only by a surface piece 19 (FIG. Fig. 7 ) extending in a second main plane H2. By the surface piece 19 results in a constructive change to the second longitudinal edge 3 '. Moreover, the striking plate 1 of the second embodiment is identical to that of the first embodiment. Therefore, the description of the second embodiment is limited to the design changes on the second longitudinal edge 3 '. For the components which are identical to those of the first embodiment in the second embodiment, the same reference numerals are also used.

The main body 2 of the striking plate 1 in Fig. 6 shows the second embodiment according to the present invention in plan view, ie with the first main plane H1. The longitudinal edge 3 'does not extend continuously between the first transverse edge 5 and the second transverse edge 5'. At the longitudinal edge 3 ', a first incision 21 and a second incision 23 are formed. In the present embodiment, the first incision 21 and the second incision 23 are formed as a material recess, so that the two incisions 21, 23 are U-shaped. Between the first notch 21 and the second notch 23 extends in the second main plane H2, the surface portion 19 ( Fig. 7 ). The surface piece 19 is formed integrally with the base body 2 in the present embodiment, and preferably a part thereof, which is bent in one operation from the first main plane H1 in the second main plane H2, that in the second embodiment of the present invention illustrated manner extends.

In other embodiments, however, the surface piece 19 may also be a separate component, which is mechanically connected to the main body 2 in any way on the longitudinal edge 3 'or is even connected to the base body only via a third component. In the one-piece design results by bending the sheet 19 between the first incision 21 and the second incision 23 a bending line 25. In the in Fig. 6 illustrated second embodiment, the bending line 25 extends parallel to the longitudinal edge 3 'and is set back a little compared to this. In other embodiments, however, the bending line 25 can also be aligned with the longitudinal edge 3 'and project even slightly therefrom. It is also conceivable that due to the U-shaped design of the notches 21, 23, a course of the bending line 25 obliquely to the longitudinal edge, that is not parallel to this, is selected.

A decision on the course of the bending line 25 depends on the dimensions of the components to be connected to the strike plate 1. The sheet 19 is used in the second embodiment of the present invention as a side cover for an electromagnetic door opener (not shown).

The surface piece 19 is U-shaped in the second main plane H2 and thus encloses an opening 27 for the door opener.

In Fig. 11 is schematically shown in plan view, the triggering device 17. The adjusting plate 17.1 is in the present embodiment, a rectangular strip with a front side 17.5. With the front side 17.5 in alignment extends to one side of the adjusting plate 17.1 of the trip stop 17.2. In the present embodiment, the trigger stop 17.2 for the latch plate 15 has a slightly shorter length than the width of the adjusting plate 17.1 and the end face 17.5. The length of the Aulöseanschlags 17.2 but may have completely different dimensions in other embodiments, which are adapted to the particular structural conditions and are also greater than the width of the adjusting plate 17.1.

Overall, the triggering device 17 has an approximately L-shaped geometry. In the adjusting plate 17.1, the slot 17.3 is formed. The trigger stop 17.2 may also be designed as a role, thereby the trip time could be reduced.

In Fig. 12 is a schematic side view of the triggering device 17 from Fig. 11 shown. The triggering device 17.1 has on a bottom 17.6 a corrugation 17.7 or toothing, which in Fig. 11 already indicated. In one of the main body 2 in Fig. 1 or Fig. 6 mounted manner, the serrations 17.7 or teeth extend in the longitudinal direction of the base body 2, so that an adjustment of the adjusting plate 17.1 can take place transversely to the longitudinal direction of the base body 2 in stages. The distances between two adjoining teeth or Riefeln is ≤ 1 mm, but can be adapted to the dimensions of the striking plate 1 and then turn out larger. The adjustment results from the length of the slot 17.3. The length of the slot 17.3 can be adapted to the size of the striking plate 1.

In Fig. 13 is schematically a section across the triggering device 17 from Fig. 11 shown.
