The invention relates to a locking part arrangement for a locking unit of a door lock, in particular for an additional locking of an espagnolette lock designed as an automatic lock,

• with a locking strip (which can be attached to a door frame or a door frame) and which has at least a first opening and a second opening for two locking elements, namely a latch bolt on the one hand and a pivot bolt on the other
• and with at least one receiving pot that can be attached or attached to the back of the locking strip (in which the locking elements engage during the locking process),
• wherein the receiving pot has at least a first pot section assigned to the first opening for the engagement of a spring-loaded latch bolt and a second pot section assigned to the second opening for the engagement of a pivot bolt,
• wherein the pivot bolt in the locking position preferably engages behind the back of the locking bar, preferably a web of the locking bar between the two openings.

Such a locking part arrangement is preferably attached to a door frame or door frame, while the door lock (with its locking unit) is attached to a door leaf/door leaf. The door lock is preferably an espagnolette lock and therefore a multiple locking system, which on the one hand has a central lock and on the other hand one or more Has additional locks or secondary locks. Particularly preferably, the espagnolette lock is an automatic lock which has at least one self-locking (auxiliary) locking unit, ie the locking elements of the locking unit (e.g. a latch bolt on the one hand and a swivel bolt or swivel hook bolt on the other) automatically move into the locking position, when the door is closed. The self-locking can be triggered magnetically or mechanically.

The locking part arrangement attached to the door frame consists of the locking strip on the one hand and the receiving pot attached to the back of the locking strip, whereby a single receiving pot or alternatively several receiving pots can be attached. The closing strip itself is usually a sheet metal part that can be designed as a flat sheet or as an angle sheet with an L-shaped or U-shaped cross section. The locking part arrangement is set up for a lock which has, on the one hand, a latch bolt and, on the other hand, a pivot bolt (in one and the same locking unit) as locking elements. The latch bolt is a spring-loaded locking element with an additional latch function, ie the latch bolt has a latch tip and a beveled operating edge extending from it and it is loaded with a latch spring in the direction of an extended locking position. The latch bolt can be retracted from a fully extended locking position (with the door closed) or a partially extended unlocking position (with the door open) into a (fully) retracted opening position, with the latch bolt in the partially extended unlocking position by a certain amount (an unlocking dimension) over the lock housing or protrudes beyond the faceplate. When the door is closed, the latch bolt's operating edge comes into contact with the locking strip is pushed back into the lock housing. As soon as the door is closed, the latch bolt is pushed forward into the receiving pot through the corresponding opening in the locking bar. In addition, a pivot bolt is provided in the locking unit as a second locking element, which is also completely released into the locking position when the door is closed. For this purpose, the lock mechanism is set up in such a way that when the door leaf is in the closed position, the pivot bolt is only moved into the fully swung-out locking position if or as soon as the latch bolt has reached or passes over a partially extended limit position in which the latch bolt is moved by a Limit dimension (e.g. 12 mm or 13 mm) protrudes, this limit dimension being larger than the unlocking dimension (e.g. 10 mm) in the unlocking position and which is also smaller than the locking dimension (e.g. approximately 20 mm) which the latch bolt assumes in the extended locking position. After being triggered accordingly, the two locking elements move into their locking positions with the door closed, but usually not simultaneously, but preferably with a time delay, so that the swivel hook bolt is only extended when the latch bolt is already immersed in the locking bar by a certain amount, so that over the Latch bolt not only locks, but also pre-centers the door and so that the swivel hook bolt can reliably dip into the area of the locking bar and reach behind the locking bar or an element arranged on or in it. Such a door lock with a latch bolt on the one hand and a swivel hook bolt on the other is characterized by a particularly high level of security and automatic function at the same time.

A locking unit or an automatic lock of this type is z. B. from the DE 10 2017 105 125 A1 known and the invention relates in particular to a locking part arrangement which can be used for such a locking unit.

The locking part arrangements that can be used in practice for such an automatic lock have proven themselves well in practice, but they can be further developed. - This is where the invention comes in.

A locking part arrangement with locking strip and bolt receiving pot, which can be used, for example. B. is designed for a swivel bolt, is z. B. from the DE 10 2013 101 033 A1 known. The pot is composed of an outer part and an inner part which is spring-loaded on it, so that a spring-loaded latch receiving part is realized, which is intended to absorb incorrect adjustments and in particular warping of the door.

The DE 10 2018 118 388 A1 describes a bolt receiving device for a swivel bolt, in which a locking plate is movably attached to the locking bar, which can be moved along the longitudinal direction of the locking bar, the locking plate being movable due to gravity into a lower basic position that partially covers the passage opening, the locking plate being in the course of pivoting in the swivel hook bolt can be lifted from the basic position by the swivel hook latch. This is intended to increase security against manipulation and consequently burglary security.

In the DE 20 2016 104 078 U1 a striking plate arrangement for an additional locking of an espagnolette lock is described, which is used in particular for fastening in a pocket-like recess of a wooden frame and which has, on the one hand, a fastening plate and, on the other hand, a locking part releasably fastened to the fastening plate. The locking part is provided on the back with a bolt receiving pot, which is preferably integrally formed on the locking part. Depending on the use for a particular type of bar, the bar receiving pot can face the floor have a tapering cross section in order to simplify the assembly of the locking part in a corresponding recess in the wooden frame.

Furthermore, in the DE 10 2016 120 657 A1 a device for receiving a latch bolt with a striking plate and a receiving body is described, the striking plate having a passage for the latch bolt and the receiving body having a receiving space adjoining the passage. The receiving space can taper in an end area.

Furthermore, it is known to provide an inclined stop surface for a spring-loaded latch or a bolt in a bolt receiving pot (cf. DE 20 2006 015 221 U1 or DE 80 30 997 U1 ).

Based on the known prior art, the invention is based on the object of creating a locking part arrangement of the type described above, which is characterized by improved functionality, particularly in connection with an automatic lock.

To solve this problem, the invention teaches in a generic locking part arrangement of the type described above, in which the receiving pot has, on the one hand, a first pot section for the latch bolt and, on the other hand, a second pot section for the pivot bolt, that in the first pot section (which is assigned to the latch bolt) at least a front inner pot wall facing the latch tip of the latch bolt is shaped in such a way and is oriented (at least in some areas) obliquely to the central axis of the pot in such a way that the latch bolt is immersed in the pot without contact up to a first immersion depth, this first immersion depth of the latch bolt permitting a release of the Swivel bolt enables or triggers and that after reaching a second immersion depth, which is greater than the first immersion depth, the latch bolt rests or comes into contact with the front inner wall of the pot and consequently touches the inner wall of the pot.

For this purpose, the pot (in the first pot section assigned to the latch bolt) can have a first immersion area that tapers in the immersion direction up to a first pot depth and an adjoining and also tapering second immersion area from the first pot depth to the bottom of the pot, the first The immersion area tapers by a maximum of 30% from an upper width at the top edge of the pot to an intermediate width at the first pot depth, whereby the second immersion area tapers by at least 50% from the intermediate width at the first pot depth to the bottom width at the bottom of the pot, so that the latch bolt up to a first immersion depth in the first immersion area (before reaching the first pot depth) immersed in the pot without contact, which enables the pivot latch to be released and that the latch bolt in the second pot area has a second immersion depth (which is greater than the first immersion depth) against the inner wall of the pot Plant comes and consequently touches the inner wall of the pot. The front wall or inner wall of the pot is consequently oriented obliquely, preferably in two different areas, i.e. initially an upper area without or with a relatively flat slope and then a lower area with a steeper slope or steeper inclination, i.e. in the deeper region of the The pot tapers more strongly, so that the latch comes into contact with the pot wall or the front wall. The top width, the intermediate width and the bottom width each refer to the distance between the front wall and the central axis of the pot, ie what is primarily important is the changing distance between the front wall and the central axis. However, the rear wall opposite the front wall is preferably also designed in the same way, so that the top width, intermediate width and bottom width can also refer to the distance between the front wall and the back wall in this first pot section. The first pot depth can be 40% to 60% of the total depth, e.g. B. 7 mm to 15 mm. The front wall and possibly the rear wall can have a smaller inclination towards the central axis in the first immersion area than in the second immersion area.

The invention is based on the knowledge that in an automatic lock with a latch bolt on the one hand and a swing bolt on the other hand, the function of the latch bolt is of particular importance, because only when the latch bolt has a certain limit of z. B. 12 mm to 13 mm protrudes from the lock housing or the lock faceplate, the swivel bolt also extends, which ensures particularly secure locking of the door. However, the combination with the latch bolt ensures that the swivel hook bolt can only be extended when it is ensured that the door is actually in the locking position and the latch bolt has retracted to a certain extent into the corresponding opening in the locking bar. The latch bolt is preferably already secured against back pressure in this position, which is extended to the limit.

In order to ensure that the latch bolt and thus also the swing bolt function properly, the opening in the locking bar and the inner dimension of the receiving pot are chosen to be large enough so that the latch bolt can both pass through the opening and engage in the entire receiving pot with sufficient play, so that With the current state of the art, the focus is on trigger safety. According to the invention, the high level of triggering reliability is maintained. Due to the design of the pot according to the invention, the latch bolt rests with its latch tip against the inner wall of the pot, namely against a specially designed pot slope, which is however so deep is arranged within the pot so that the retraction of the latch bolt is initially ensured beyond the limit required to trigger the swivel hook bolt. The pot according to the invention or the relevant pot section for the latch bolt is characterized in that a sufficient width is available in the upper area for a high degree of triggering security. In the lower area, however, the pot is greatly tapered or there is at least one sloping inner wall against which the latch bolt comes to rest with its bolt tip. This also ensures that the latch bolt pulls the door properly into the locking position through contact with the pot, even against a certain pressure from a door seal, so that a high degree of tightness is also achieved via the design according to the invention.

It is also particularly important that security against burglary and tampering is not impaired, even if the latch bolt is not fully extended due to the slope or thickening within the pot provided according to the invention. Because the locking part arrangement according to the invention is particularly preferably used in an automatic lock in which the latch bolt is activated after the limit dimension of z. B. 12 mm to 13 mm is secured against back pressure, so that the latch bolt is reliably prevented from being pushed back even if the latch bolt is not fully extended. Furthermore, the latch bolt is particularly important in combination with the swivel hook bolt, so that the combination achieves a high level of security.

According to the invention, the described design of the pot or the inner walls of the pot and the inner diameter of the pot refers to the first Pot section, which is assigned to the latch bolt. As described, the pot also has a second pot section into which the pivot lock engages. This pot section does not need to be modified, ie the pot geometry in the area of this second pot section can be adopted unchanged from the prior art.

Optionally, there is also the possibility that the closing strip additionally has a third opening and the receiving pot additionally has a third pot section for the engagement of a further bolt, with the second pot section for the pivot bolt lying between the first pot section and the third pot section. This means that, in a generally known manner, a locking strip with a bolt receiving pot can be provided, which is set up for three locking elements and which can also be used universally. One and the same locking bar can be used, for example: B. can be used for an automatic lock with a latch bolt on the one hand and a swivel bolt on the other. However, the same locking part arrangement can also be used for a manually or motor-operated locking unit with two bolt bolts and a pivot bolt arranged between them or for a locking unit with only one or two bolt bolts or only one pivot bolt or a latch bolt. According to the invention, however, the use of the locking part for an automatic lock with a latch bolt on the one hand and a swivel hook bolt on the other is of particular importance.

Particularly preferably, the pot attached to the rear of the closing strip is formed in one piece with the first pot section and the second pot section and, if necessary, the third pot section, that is, a uniform pot is realized which only has a plurality of pot sections arranged one above the other, with a partition wall between the pot sections if necessary can be provided. However, it is particularly preferred that no partition wall is implemented between the first pot section and the second pot section, so that the first pot section merges directly into the second pot section, although the wall geometry in the first pot section differs from the wall geometry in the second pot section. Alternatively, however, a pot can also be used in which the individual pot sections are formed by several separate pots, ie several individual pots are attached to the back of the closing strip with the several openings, which form the pot sections mentioned.

The receiving pot is preferably manufactured as a separate component, which is attached to the back of the closing strip, e.g. B. by means of screw connections, rivet connections, clip or clamp connections or the like. However, there is also the option of manufacturing the receiving pot in one piece with the closing strip. The closing strip is particularly preferably designed as a sheet metal part, e.g. B. as a flat sheet or as an angle sheet with a U-shaped or L-shaped cross section. The pot attached to the back with screws, rivets or the like can be made of metal, e.g. B. as a die-cast part. Alternatively, the pot can also be made of plastic.

Finally, the invention also relates to a locking system for a door with a locking part arrangement of the type described and with an espagnolette lock which, on the one hand, has a central lock and, on the other hand, at least one additional lock, the additional lock having, on the one hand, a latch bolt and, on the other hand, a pivot bolt. Particularly preferably, it can be a locking system with an automatic lock and consequently with at least one self-locking additional lock, which, for. B. in the DE 10 2017 105 125 A1 is described.

In Fig. 1 an espagnolette lock 1 with multiple locking is shown in the embodiment as a self-locking automatic lock. Fig. 1 shows, on the one hand, an espagnolette lock 1 that can be mounted or mounted on a door leaf and, on the other hand, a locking part arrangement 2, which is attached or is attached to a door frame or a door frame. The espagnolette lock 1 has several locking units, on the one hand a central lock 3 and on the other hand one or more additional locks 4, which are attached to the back of a (common) lock faceplate 6. When a handle is operated and/or a key is operated, on the one hand, The central lock 3 is unlocked and, on the other hand, the additional locks 4 are unlocked via the drive rods 25, which are only indicated. The additional locks 4, which can be actuated via the drive rods 25, each have a lock housing 5 and two locking elements, namely on the one hand a latch bolt 7 and on the other hand a pivot bolt 8. Details are exemplified in Fig. 2 shown, namely in an unlocking position, e.g. B. with the door open. The latch bolt 7 has a latch tip 7a and a beveled operating edge 7b and it is loaded with a latch spring 13 in the direction of an extended locking position. In the in Fig. 2 In the partially extended unlocking position shown, the latch bolt 7 protrudes by an unlocking dimension from the lock housing or over the faceplate 6. The latch bolt 7 or the lock chain 14 of the additional locking is held in the unlocking position shown by a locking element 9. In addition to the latch bolt 7, the pivot bolt 8 is provided, which is retracted into this unlocking position. If the door is now starting from the in Fig. 2 In the unlocking position shown, the latch bolt 7 is first pushed back by contact with the frame-side locking part 2 and as soon as the door is completely closed, the latch bolt 7 extends again due to the spring load. In this position, the locking element 9 is actuated to automatically lock the locking unit in such a way that the latch bolt 7 or the lock chain 14 is released, so that the latch bolt 7 is automatically moved into the extended locking position. The pivot bolt 8 is also moved into the locking position, but with a time delay, because with the automatic lock it is provided that the pivot bolt 8 is only transferred to the swung-out locking position when the door leaf is in the closed position when the latch bolt 7 reaches or passes over a partially extended limit position which of the latch bolts 7 projects out of the lock housing 5 or over the forend 6 by a limit that is greater than the unlocking dimension in the unlocking position. In the exemplary embodiment shown, the self-locking is triggered magnetically by the locking element 9 being actuated by a magnet 10 arranged on the frame side. Alternatively, however, a generally known mechanical triggering of the self-locking can also take place. At the in Fig. 2 The lock shown is an example of an embodiment that, for. B. in the DE 10 2017 105 125 A1 is described.

The invention relates in particular to those in the Figures 1 and 2 only indicated locking part arrangement 2, which is attached to the frame side and which is preferably set up for such an automatic lock.

Such a locking part arrangement 2 consists in a generally known manner of a locking strip 11 on the one hand and a receiving pot 12 attached to the back of the locking strip on the other hand. Separate locking part arrangements 2 can be used for the individual locks of an espagnolette lock and fastened on the frame side. However, it is also possible to use a continuous locking strip for the entire espagnolette lock. The locking strip 11 has in the area of the additional lock 4 at least a first opening 15 and a second opening 16 for the locking elements 7, 8, namely the latch bolt 7 on the one hand and the pivot bolt 8 on the other. In addition, the closing strip in the exemplary embodiment has a third opening 17 for a further locking element, e.g. B. for a bolt bolt. The receiving pot 12 has pot sections corresponding to the individual openings 15, 16, 17, ie at least a first pot section 18 and at least a second pot section 19 and optionally also a third pot section 20. The first pot section 18 is assigned to the first opening 15 and for the Engagement of the spring-loaded latch bolt 7 is determined.

The second pot section 19 is assigned to the second opening 16 and is intended for the engagement of the pivot bolt 8. In the locking position, the pivot bolt 8 engages behind the back of the locking bar 11. The invention is particularly concerned with the design of the first pot section 18, which is specially designed for the engagement of the latch bolt 7. This results from Fig. 3 as well as from a comparative consideration of the Figures 4A to 4E on the one hand and the Figures 5A to 5E on the other hand, where the Figures 5A to 5E show an arrangement known from the prior art.

They show Figures 4A to 4E on the one hand and Figures 5A to 5E on the other hand, the locking part arrangement 2 and the associated latch bolt 7 are in different functional positions, ie with different immersion depths, when the door is closed. In the Figures 5A to 5E It can be seen that in the prior art the latch bolt 7 can dip into the pot 12 perfectly in the optimal mounting position and generally without touching the wall. This shows Fig. 5E (right) the situation in which the latch bolt 7 of an automatic lock is extended beyond the limit and is therefore immersed in the receiving pot 12 to such an extent that the pivot bolt 8 is triggered in this functional position and thus swings out. From this limit position onwards Fig. 5A the latch bolt 7 is already secured against back pressure. Since extending to this limit position is of particular importance for the automatic release of the swivel bolt 8, the receiving pot 12 in the prior art is dimensioned so that there is sufficient play for perfect immersion without touching the wall. Overall, the latch bolt 7 in the prior art can immerse itself in the pot without contact when in the optimal mounting position.

In contrast, they show Figures 4A to 4E in combination with Fig. 3 the design of the receiving pot according to the invention, in which in particular the front inner pot wall 21 facing the latch tip 7a of the latch bolt 7 is particularly adapted to the situation, the representation in the Figures 4A to 4E refers to the first pot section 18 assigned to the latch bolt 7. The front inner wall of the pot 21 is designed in such a way that the latch bolt is immersed in the pot without contact up to a first immersion depth, which enables the pivot latch 8 to be released and that the latch bolt 7, after reaching a second immersion depth that is greater than the first immersion depth, against the front inner pot wall 21 rests. For this purpose, the inner wall of the pot 21 in the exemplary embodiment is oriented obliquely to the central axis M of the pot, so that the receiving pot 12 has a first immersion area that tapers in the immersion direction up to a first pot depth T1 and an adjoining and also tapering second immersion area from the first pot depth T1 to to the bottom of the pot T2, so that the latch bolt is immersed in the pot without contact up to a first immersion depth in the first immersion area and the latch bolt in the second immersion area rests against the inner wall of the pot from a second immersion depth.

So shows Fig. 4E the situation in which the latch bolt 7 is extended sufficiently for the self-locking of the swing bolt and up to the in Fig. 4E At the first immersion depth shown, the latch bolt can always be immersed in the pot without touching it. As it progresses, however, the latch bolt then reaches the in Fig. 4B shown second immersion depth, at which the latch bolt rests with its bolt tip against the front inner pot wall 21. A comparison to the corresponding one Fig. 5B makes it clear that this prevents movement of the latch bolt relative to the pot.

In the exemplary embodiment shown, the first immersion area tapers from the upper width B0 at the top edge of the pot T0 to an intermediate width B1 at the first pot depth T1 by a maximum of 30%. The second immersion area tapers by at least 50% from the intermediate width B1 at the first pot depth T1 to the bottom width B2 at the pot bottom T2. In the exemplary embodiment, the front wall is therefore oriented obliquely, preferably in two different areas, i.e. H. initially an upper area with a relatively flat slope based on the central axis M, i.e. H. in the figures based on the vertical, and an adjoining lower area with a greater gradient or inclination, i.e. H. In the deeper area of the pot, the pot tapers more so that the latch 7 comes into contact with the pot wall or front wall 21.

It can be seen in the figures that the pot is designed essentially symmetrically, ie the rear wall 22 of the pot is also designed obliquely in the same or similar manner. However, the invention also includes embodiments in which the rear wall 22 (which is shown on the left in the figures) is designed in a conventional manner, ie the rear wall according to the Figures 4A to 4E could also be designed like the rear wall 22, which is in the Figures 5A to 5E is shown.

Incidentally, in Fig. 3 It can be seen that the design according to the invention relates primarily to the first pot section 18, which is intended for the latch bolt 7. The second pot section 19 and the third pot section 20 can be designed in a conventional manner, ie no further adjustment is required for the pivot bolt 8. In the espagnolette lock shown with latch bolt 7 and swing bolt 8 in the additional lock only the first pot section and the second pot section are used.

Alternatively, the receiving pot can be used universally, e.g. B. also for a drive rod lock from the prior art, in which two bolt bolts and a swivel hook bolt between them or just two bolt bolts are provided, the first pot section 18 and the third pot section 20 being intended for the bolt bolts in this case, while the second Pot section 19 can be provided for a swivel bolt. Alternatively, there are also additional locks, e.g. B. only have a central latch bolt or only a central bolt bolt or just a central pivot bolt. All of these locking units can be used with the universally applicable locking part or receiving pot.

This is the case in the exemplary embodiment Fig. 3 It can be seen that a partition 23 is provided between the second pot section 19 and the third pot section 20, while no partition wall is provided between the first pot section 18 and the second pot section 19, since in this area the pivot bolt 8 covers the web 24 between the first opening 15 and the second opening 16 of the closing part 11 must reach behind.
