Description

The invention relates to a bolt receiving device for a locking device having at least one swivel hook bolt, with a locking bar which has a passage opening for a swivel hook bolt.

Such a locking bar, which is also referred to as a striking plate or locking part, is preferably attached to a door frame of a door or to a window or window frame. The locking device is preferably a door lock, for example a multi-point lock, which can be designed, for example, as an espagnolette lock, such an espagnolette lock having, for example, a central lock (center lock) and one or more additional locks or additional locks. The center lock has, for example, a central bolt and possibly a lock latch, while the additional locks have one or more additional bolts which are preferably designed as swivel hook bolts in the context of the invention. In this respect, the bolt receiving device according to the invention is preferably assigned to an additional lock of a multi-point lock. In the course of locking, the swivel hook bolt z. B. pivoted about an axis and in the course of pivoting the hook hook engages in the passage opening and engages behind the locking bar. The locking device, which is designed, for example, as an additional lock, generally has a lock housing or a lock case, in which the swivel hook bolt is pivotably mounted. For this purpose, the swivel hook bolt can have a base section pivotally attached to the lock housing with a swivel axis and a hook section connected to the base section and protruding from the lock housing in the locking position (L-shaped). The end leg of this L-shaped hook portion engages behind in the locking position Locking bar. In order to maximize the security against burglary, it is expedient that this end leg of the swivel hook bolt reaches behind the locking bar as far as possible and consequently with a maximum overlap.

The locking bar can be designed as a flat plate or as an angle plate with an L-shaped or U-shaped cross section. In the area of the passage opening, a (pot-like) bolt receiving part and, consequently, a bolt receiving pot, into which the swivel hook bolt engages, can optionally be arranged on the rear. In the case of multiple locking, the additional lock can be assigned its own separate locking bar. However, a continuous locking bar can also be used, which has passage openings for the different locks at different heights.

The positioning of the bolt receiving device or the locking bar is of particular importance in practice, because with different profile systems and rubber seals there is a need to be able to mount a locking part in different positions so that the locking elements of the door, e.g. the hook hook or bolts can properly engage in the locking part. If necessary, the adjustment is also carried out in such a way that the bolt or bolts lock the door, e.g. Front door, always pull gently into the door seal. In practice there is the problem that doors, e.g. Wooden doors or plastic doors can warp due to the different weather or temperature conditions.

Against this background, the DE 10 2013 101 033 A1 a bolt receiving device with a locking bar and a bolt receiving part fastened to it, which has an outer part that can be fastened to the locking bar and an inner part that is movably arranged in the outer part, into which a bolt of the door lock engages, the inner part by means of a spring device is held in a basic position from which the inner part can be deflected along the closing direction of the door against the spring force of the spring device and the basic position of the inner part can be changed with an adjusting device. The outer part can be pot-shaped and the inner part arranged therein can also be pot-shaped. The adjusting device can preferably have an eccentric part. With this configuration, in particular the adjustment along the closing direction of the door can be optimized.

Regardless of this, in practice there is the problem of adjusting the door along the longitudinal direction of the locking bar, which is generally oriented perpendicular to the closing direction of the door and consequently vertically in space. Problems can occur in particular when the door leaf lowers relative to the door frame and thus also relative to the locking bar attached to the door frame, since this reduces the engagement of the swivel hook bolt behind the locking bar or the overlap between the swivel hook latch and locking bar. In the case of conventional locking strips, such a reduced overlap leads to a reduction in the security against burglary or manipulation. - The invention seeks to remedy this.

The invention has for its object to provide a bolt receiving device for a locking device with swivel hook bolt of the type described above, which is characterized by improved security against manipulation and consequently security against burglary.

To achieve this object, the invention teaches in a generic bolt receiving device of the type described at the outset that a locking plate is movably attached to the locking bar and can be displaced (by a predetermined amount) along the longitudinal direction of the locking bar, wherein the locking plate can be moved by a force into a basic position partially covering the passage opening (and consequently reducing) and can be moved against the force by the swivel hook bolt from the basic position in the course of the pivoting of the swivel hook bolt, e.g. B. can be raised. In the course of this movement, e.g. B. Lifting consequently the partial covering of the passage opening realized by the blocking plate is at least partially canceled again and consequently the passage opening is released.

The invention is based on the knowledge that the swivel hook bolt (eg an additional locking device) in the known locking devices (eg espagnolette locks) z. B. engages by a pivoting movement from below (or from above) into the passage opening of the locking bar and consequently the rear bar engages with its end with a certain overlap above the passage opening. If the door leaf sinks in relation to the door frame and thus also with respect to the locking bar, this overlap is reduced. This is counteracted according to the invention by the locking plate which is attached to the locking bar and with the door open in a (lower) basic position z. B. drops due to gravity in the area of the passage opening and thus reduces the passage opening in the upper region. In the event that the door leaf sinks, an enlarged area is consequently made available with the help of the locking plate, so that the swivel hook bolt behind the locking bar and behind the locking plate again achieves a sufficient overlap that is not only on the locking bar itself, but also relates to the locking plate. It is important that this locking plate can be easily lifted against gravity when the swivel hook bolt is swung in, so that the locking plate does not adversely affect the movement of the swivel hook bolt even if the door leaf is at the originally intended height, which is generally at such a height Locking plate could be dispensed with. The agility of the Locking plate along the longitudinal direction of the locking bar consequently means that the swivel hook bolt can be easily pivoted into the passage opening in a conventional manner and that the locking plate always falls down in the lock until it either reaches its end stop or bears against the swivel hook bolt. An optimal level of manipulation security is always guaranteed without the operation of the lock being impaired.

The invention can first of all be implemented in basically known locking devices in which the swivel hook bolt is oriented such that it swivels into the area of the locking bar from below, ie. H. the hook end of the swivel hook bolt is oriented upwards. In this case, the invention proposes that the locking plate by a force, for. B. the gravity, is movable into a lower basic position and in the course of pivoting the swivel hook bolt, the locking plate against this force, for. B. Gravity.

However, the invention also includes those embodiments in which the swivel hook bolt is swiveled in a swiveling movement from above into the area of the locking bar and consequently enters the through opening from above. In this embodiment, the hook end of the swivel hook bolt is oriented downwards in the locked state. In such an embodiment, it is useful if the locking plate with a force, for. B. a spring force, is moved into an upper basic position, the locking plate in the course of the pivoting of the swivel hook bolt by the swivel hook bolt from this upper basic position against the force, for. B. spring force, can be lowered. In such an embodiment, at least one spring or a spring element is preferably provided, which acts on the locking plate in its upper basic position. A feather or one However, the spring element can also be useful in an embodiment in which the locking plate is already moved into a lower basic position due to gravity, because in this case the lowering can be supported by the force of an additional one.

In a preferred embodiment, the locking plate is attached to the rear of the locking bar and the swivel hook bolt engages behind the rear of the locking plate in the locking position. Rear of the locking bar means the side of the locking bar facing away from the lock in the closed position of the door and consequently the side of the locking bar facing the door frame. The invention relates equally to windows or the like.

The locking plate is preferably plate-shaped, in such a way that it covers an upper region of the passage opening in a lower basic position or covers a lower region of the passage opening in an upper basic position. This succeeds e.g. in that the locking plate itself also has an opening, which in the basic position is only partially aligned with the passage opening of the locking bar and which is delimited by an upper (or lower) actuating edge, against which the swivel hook bolt moves as it swings in, raising (or lowering) the locking plate can work.

In this case, the swivel hook bolt has, in a known manner, a base section which is pivotally attached to a lock housing with a swivel axis and a hook section which is connected to the base section and projects into the locking position from the lock housing (L-shaped). The actuating edge of the locking plate, which delimits the opening on the upper side (or lower side), is preferably from an inner one Actuating surface of the hook section of the swivel hook bolt can be raised or lowered.

There are various ways of constructively realizing the invention or the locking plate. In a first embodiment, in addition to the rear locking plate, a front holding plate is provided, the rear locking plate being slidably attached to the locking bar together with the front holding plate. The locking plate and the holding plate can be connected to one another with the interposition of the closing bar (parallel to one another), preferably with the interposition of one or more spacer elements or guide elements which are guided in the passage opening.

In a second embodiment, a bolt receptacle is attached to the rear of the locking bar. The locking plate is slidably guided between the locking bar and the bolt receptacle. In this embodiment, a front holding plate can be dispensed with. The locking plate, which is essential to the invention, can be guided very easily between the locking receptacle fundamentally known from practice and the rear of the locking bar, in such a way that the lowering (or lifting) of the locking plate into the basic position is limited by a stop. In a particularly preferred development, the bolt receptacle is fastened to the locking bar in an adjustable manner in the transverse direction or in the closing direction of the door and consequently perpendicular to the longitudinal direction of the locking bar, without the position of the locking plate and the mobility of the locking plate being influenced in the course of this adjustment. For adjustment, the bolt receptacle can be attached to the locking bar with one or more adjusting elements. These adjusting elements can be eccentric adjusting elements, for example. In this preferred embodiment of the invention, misalignments are consequently on the one hand of the door in the vertical direction and consequently along the longitudinal direction of the locking ledge are compensated for by the locking plate according to the invention, and at the same time incorrect adjustments in the closing direction of the door oriented perpendicular thereto can be compensated for by the adjustability of the bolt receiving pot.

The locking bar can basically be designed as a simple, flat locking plate or as a flat sheet. However, it is preferably designed as an angle plate with an L-shaped or particularly preferably with a U-shaped cross section. In this case, it has a base plate forming the U-base and two side legs connected to the base plate and forming the U-legs. In such an embodiment, the locking plate is preferably guided on the back of the base plate and optionally laterally between the side legs or in some other way.

The passage opening of the locking bar preferably has a height (along the locking bar longitudinal direction) of 10 mm to 50 mm, e.g. 20 mm to 40 mm. It is expedient if the locking plate covers the (upper) area of the passage opening in the (lowered) basic position by a predetermined amount (along the longitudinal direction of the locking bar). This measure can e.g. 5 mm to 15 mm. It is always expedient if the locking plate can be raised (or lowered) to the extent that the passage opening is completely or at least essentially completely cleared in the course of the pivoting in of the swivel hook bolt.

The invention also relates to a locking device with a (door) lock (attached or attachable to a door leaf or window leaf), for example with an espagnolette lock which has at least one swivel hook bolt, and with a (arranged on a door frame or window frame or fastenable) bolt receiving device of the type described. The bolt receiving device according to the invention is consequently also protected in combination with a lock or door lock, for example with an espagnolette lock, and consequently as part of a locking device. Because the bolt receiving device according to the invention is of particular importance in cooperation with the swivel hook bolt of a lock. The swivel hook bolt is preferably part of an additional locking mechanism of an espagnolette lock.

The locking bar is preferably made of metal, e.g. as a U-shaped sheet metal part. The locking plate is also preferably made of metal, e.g. as a flat sheet with a cut-out as an opening. The latch pot can also be made of metal, e.g. be designed as a casting. Alternatively, the bolt receiving pot can also be designed as a molded plastic part.

In Fig. 1 a locking system with multiple locking for a door is shown. In the exemplary embodiment, the multi-point lock is designed as an espagnolette lock 1 with a central lock 2 and additional locks 3, each of the locks 2, 3 having at least one bolt. In the additional locks, the bolts are designed as swivel hook bolts 4. The espagnolette lock 1 is attached to the door leaf 5. The invention relates to the locking bar 7, which is associated with the additional lock 3 with swivel hook bolt 4. This locking bar 7 has a passage opening 8 for the swivel hook bolt 4. In the course of locking the espagnolette lock 1 and consequently also the additional locking 3, the swivel hook bolt 4 is pivoted about its axis 9 and in the course of the pivoting it passes through the passage opening 8 and engages behind the locking bar 7. In the exemplary embodiment, the pivoting of the pivot hook bolt 4 is not Driving rod shown causes, which can for example be in operative connection with the central lock 2 and / or can be actuated via a motor drive. In this respect, the swivel hook bolt 4 can be transferred to the locking position manually, for example, by key actuation or handle actuation of the central lock 2, or automatically (mechanically) transferred to the locking position when the door is closed, or automatically or manually triggered by a motor drive. Details are not shown.

The swivel hook bolt 4 has a base section 4a pivotally attached to a lock housing 10 with the swivel axis 9 and an L-shaped hook section 4b connected to the base section 4a and projecting out of the lock housing 10 in the locking position. In a normal position, the hook section 4b engages behind the locking bar 7 or the rear thereof by a predetermined amount, which represents the overlap of the hook section 4b with the locking bar 7.

Problems occur in the prior art when the door leaf 5 sinks down relative to the door frame 6 and thus the dimension M, ie the overlap, is reduced. This is counteracted according to the invention in that a locking plate 11 is movably attached to the locking bar 7, the locking plate 11 being displaceable along the longitudinal direction X of the locking bar 7. In the exemplary embodiment, this locking plate 11 sinks due to gravity until it reaches a lower basic position due to a stop (not shown in more detail), in which the passage opening 8 of the closing strip 7 is partially covered in the upper region. This increases the area that the swivel hook bolt 4 or its L-shaped hook section 4b can reach behind in the locking position, so that the security against manipulation is increased. It is also important that this locking plate 11 can be raised against the force of gravity from the basic position in the course of the pivoting of the swivel hook bolt 4 by the swivel hook bolt - if this is necessary due to the positioning. The pivoting of the swivel hook bolt 4 is consequently not affected by this movable locking plate 11. In any case, it is possible in this way that the swivel hook bolt 4 engages behind the lowered locking plate 11 in the locking point.

The locking plate 11 is preferably fastened on the rear to the locking bar 7 and the swivel hook bolt 4 engages behind the rear of the locking plate 11 in the locking position. In the illustrated exemplary embodiments, the locking plate 11 has an opening 12 which, in the basic position, is only partially aligned with the passage opening 8 of the locking bar 7 and which is delimited by an upper actuating edge 13 against which the swivel hook bolt 4 is raised in the course of the pivoting in, with the locking plate being raised 11 can work. This upper actuating edge 13 of the locking plate 11 can be raised by an inner actuating surface 4c of the hook section 4b of the swivel hook bolt 4.

The Figures 2 and 3rd show a first embodiment of the invention, in which the rear locking plate 11 is slidably attached to the locking bar 7 together with a front holding plate 14. The locking plate 11 and the holding plate 14 are connected to each other with the interposition of the locking bar 7 spaced parallel to one another, preferably with the interposition of one or more spacer elements or guide plates 15 which are guided to guide the locking plate 11 in the passage opening of the locking bar. The spacer elements or guide plate 15 can be made somewhat thicker than the locking bar or its base plate 7a, so that the locking plate 11 and the holding plate 14 are arranged at a sufficient distance and consequently with play, so that the locking plate easily falls into the basic position due to gravity and can be easily raised against gravity with the swivel hook bolt 4. The locking plate 11 and the holding plate 14 can be connected to one another with the interposition of the spacer elements 15 by means of one or more screws 16 or similar connecting means. Incidentally, is in Figure 3 indicated by way of example that the opening 12 of the locking plate 11 and / or the opening in the holding plate 14 and / or the passage opening 8 of the closing strip 7 need not be rectangular and in particular does not have to have any straight side edges. Rather, an embodiment is shown in which one or both side edges are arcuate in such a way that, for. B. the opening 12 in the central region (based on the height) has a greater width than in the upper region and / or lower region. This configuration can relate to the opening of the locking plate and / or the passage opening 8 of the locking bar and / or the holding plate 14, which likewise has an opening. Overall, one or more curved side edges can be used to optimize the pivoting of the pivot bolt and at the same time there is the possibility that the pivot hook bolt gently pulls the door against the door frame or into the lock by pivoting the pivot hook bolt along the curved side edge of the passage opening or Breakthrough slides.

In the Figures 4a , b , 5a , b and 6 such as 7a, 7b a second embodiment of the invention is shown, which relates to a preferred development. The Figures 4a and 5a show a first functional position with the lock open and consequently the swivel hook bolt not swung out. The Figures 4b and 5b in contrast show the locking position with the swivel hook bolt pivoted out, ie the swivel hook bolt extends through the passage opening 8 of the locking bar 7. Figure 7a shows the locking bar in the functional position Figure 4a , 5a in a perspective view. Figure 7b shows the locking bar Figure 7a in an exploded view. In this embodiment, a locking receptacle 17 is attached to the rear of the locking bar 7 in a generally known manner. In this locking receptacle 17, the swivel hook bolt 4 or its end hook section 4b engages in the locking position. Such a bolt receptacle 17 is intended, among other things, to manipulate the Avoid locking position. In this embodiment, the locking plate 11 according to the invention is displaceably guided - along the longitudinal direction X - between the locking bar 7 (or the rear of the locking bar) and the locking receptacle 17. In this embodiment too, the closing strip is preferably U-shaped in cross-section with a base plate 7a forming the U-base and two side legs 7b connected to the base plate and forming the U-legs. The locking plate can be dimensioned such that it is guided on the back of the base plate 7a and between the side legs 7b. In the illustrated embodiment, however, the locking plate 11 is guided along the longitudinal direction X on the bolt receiving pot using suitable means. Overall, a very simple and at the same time flawless guidance of the locking plate along the longitudinal direction X is also successful in this embodiment.

In the exemplary embodiment shown, the locking receptacle 17 is fastened to the locking bar 7 so as to be adjustable in a transverse direction Y, in such a way that the position of the locking plate itself is not influenced. For this purpose, the bolt receptacle 17 is fastened to the locking bar with several adjusting elements 18, these adjusting elements 18 being designed as eccentric adjusting elements in the exemplary embodiment. In the course of the rotation of the eccentric adjusting elements 18, the end-side eccentric bolts 18a act on the bolt receiving pot 17 in such a way that the latter is displaced in the transverse direction Y. In this way, the locking receptacle 17 can be correctly adjusted in the transverse direction Y.

Both in the embodiment according to the Figures 2 and 3rd as well as in the embodiment Figures 3 to 6 the locking plate 7 is fastened to the locking bar in such a way that the sinking into the basic position is limited, for example via a suitable stop. It ensures that the locking plate protrudes into the passage opening by a predetermined dimension M and thus reduces the length of the passage opening by a dimension M of, for example, 5 mm to 10 mm.

In addition, the figures show an example of an embodiment in which the swivel hook bolt 4 passes through the passage opening 8 of the locking bar 7, as it were, from below. In this case, the locking plate 11 already drops into the lower basic position by gravity. Optionally, this can be supported by the force of an additional actuation spring. In any case, the swivel hook bolt 4 lifts the locking plate 11 in the course of the swiveling in, in that the swivel hook bolt works on the upper actuating edge 13 of the opening 12.

However, the invention can equally be implemented in locking systems in which the swivel hook bolt 4 is pivoted in the reverse orientation into the area of the locking bar, ie. H. the swivel hook bolt is swiveled through the passage opening from above. In this case, the locking plate 11 is subjected to a suitable force in the opposite direction and consequently against gravity, e.g. B. with an actuating spring which lifts the locking plate into the basic position. In the course of locking, the swiveling hook swiveling in from above can lower the locking plate against the force of the actuating spring, for example by works against a lower operating edge of the passage opening. Such an embodiment is not shown. However, all of the options shown in the figures also relate to such an embodiment.

Otherwise, a swivel hook bolt is shown only as an example, which can be swiveled about a (fixed) axis. The concept of the hook bolt However, equally captures those embodiments in which the swivel hook bolt is not pivoted about a fixed axis, but z. B. moved on an arcuate path in the manner of a pivoting movement. Details are not shown in the figures.
