Definitions

  • Such a locking part arrangement is preferably fastened to a door jamb or door frame, while the door lock (with its locking unit) is fastened to a door wing/door leaf.
  • the door lock is preferably an espagnolette lock and consequently a multi-point lock, which on the one hand has a central lock and on the other hand one or more Has additional locks or secondary locks.
  • the espagnolette lock is particularly preferably an automatic lock which has at least one self-locking (secondary) locking unit, i.e. 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 latch bolt is a spring-loaded locking element with an additional latch function, ie the latch bolt has a latch tip and a beveled actuating edge descending therefrom and it is loaded with a latch spring in the direction of an extended locking position.
  • the latch bolt is retractable from a fully extended latched position (with the door closed) or a partially extended unlatched position (with the door ajar) to a (fully) retracted open position, with the latch bolt in the partially extended unlatched position extending a certain distance (an unlatched dimension) over the lock body or protrudes beyond the forend.
  • the latch bolt comes into contact with its actuating edge and the closing strip is pressed back into the lock housing.
  • a swivel bolt is provided in the locking unit as a second locking element, which is also fully pivoted into the locking position when the door is closed.
  • the lock mechanism is set up in such a way that when the door leaf is in the closed position, the swivel bolt is only moved into the fully pivoted locking position when or as soon as the latch bolt has reached or passed a partially extended limit position in which the latch bolt is rotated by a Limit dimension (of e.g. 12 mm or 13 mm) protrudes, this limit dimension being larger than the unlocking dimension (of e.g.
  • the two locking elements move into their locking positions after being triggered accordingly, but usually not simultaneously, but preferably with a time delay, so that the hook bolt is only extended when the latch bolt has already entered the locking rail by a certain amount, so that the Latch bolt not only a locking, but also a pre-centering of the door and thus the hook bolt dip reliably into the area of the locking bar and the locking bar or an element arranged thereon or therein can reach.
  • a door lock with latch bolt on the one hand and hook bolt bolt on the other is characterized by a particularly high degree of security with simultaneous automatic function.
  • a locking unit or an automatic lock of this type is z. B. from the DE 10 2017 105 125 A1 is known and the invention relates in particular to a locking part arrangement which can be used for such a locking unit.
  • the DE 10 2018 118 388 A1 describes a bolt receiving device for a swing bolt, in which a blocking plate is movably fastened to the locking bar and can be displaced along the longitudinal direction of the closing bar, the blocking plate being movable under the force of gravity into a lower basic position partially covering the through-opening, the blocking plate breaking in the course of the pivoting hook bolt pivoting in can be lifted from the basic position by the hook bolt. This is intended to increase security against manipulation and consequently burglary security.
  • the invention is based on the object of creating a locking part arrangement of the type described at the outset, which is characterized by improved functionality, particularly in connection with an automatic lock.
  • the invention teaches that 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 swivel bolt, that in the first pot section (which is assigned to the latch bolt) at least a front inner wall of the pot facing the locking tip of the latch bolt is shaped in such a way and is oriented (at least in certain areas) obliquely to the central axis of the pot in such a way that the latch bolt is immersed into the pot up to a first immersion depth without contact, with this first immersion depth of the latch bolt releasing the Pivot bolt allows or triggers and that the latch bolt after reaching a second immersion depth that is greater than the first immersion depth, rests against the front inner wall of the pot or comes to rest and consequently touches the inner wall of the pot.
  • the pot in the first pot section assigned to the latchbolt
  • the front wall or inner wall of the pot is therefore oriented obliquely, preferably in two different areas, i.e.
  • the top width, the intermediate width and the bottom width each relate to the distance between the front wall and the central axis of the pot, ie it primarily depends on the changing distance between the front wall and the central axis.
  • the rear wall opposite the front wall is preferably designed in the same way, so that the top width, intermediate width and bottom width can also relate to the distance between the front wall and the rear wall in this first pot section.
  • the first pot depth can be 40% to 60% of the total depth, z. B. 7mm to 15mm.
  • the front wall and optionally 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 finding that in an automatic lock with latch bolt on the one hand and swivel bolt on the other hand, the function of the latch bolt is of particular importance, because only when the latch bolt has moved by a certain limit of z. B. 12 mm to 13 mm overhangs the lock housing or the lock forend, the swing bolt also moves out, which ensures that the door is locked particularly securely.
  • the combination with the latch bolt ensures that the hook bolt can only be extended when it is certain that the door is actually in the locked position and the latch bolt has retracted a certain amount into the corresponding opening in the locking bar.
  • the latchbolt is preferably already secured against being pushed back in this position, which is extended to the limit dimension.
  • the opening in the lock rail and the inner dimensions of the receptacle are selected to be large enough that the latchbolt can penetrate the opening and also engage in the entire receptacle with sufficient play with the state of the art, the safety against triggering is in the foreground. According to the invention, the high triggering safety is retained. Due to the design of the pot according to the invention, the latch bolt rests with its bolt tip against the inner wall of the pot, namely against a pot slope specially provided for this purpose, which is, however, arranged so deep inside the pot that initially the retraction of the latch bolt exceeds that required for triggering the swivel hook bolt limit is ensured.
  • the locking part assembly according to the invention is particularly preferably used in an automatic lock in which the latch bolt after exceeding the limit of z. B. 12 mm to 13 mm is secured against being pushed back, so that the latch bolt is also reliably prevented from being pushed back if the latch bolt is not fully extended.
  • the latchbolt is particularly important in combination with the hook bolt, so that a high degree of security is achieved through the combination.
  • the configuration of the pot or the inside walls of the pot and the inside diameter of the pot described relates to the first pot section, which is assigned to the latch bolt.
  • the pot also has a second pot section into which the swivel lock engages.
  • This cup section does not have to be modified, ie the cup geometry in the area of this second cup section can be adopted from the prior art without being changed.
  • the locking strip also has a third opening and the receiving pot also has a third pot section for the engagement of a further bolt, the second pot section for the swivel bolt lying between the first pot section and the third pot section.
  • a locking strip with a bolt receiving pot can be made available, which is set up for three locking elements and which can also be used universally. So one and the same locking bar z. B. for an automatic lock with latch bolt on the one hand and swing bolt on the other hand.
  • the same locking part arrangement can also be used for a manually or motor-actuated locking unit with two bolt bolts and a swivel bolt arranged between them, or also for a locking unit with only one or two bolt bolts or only one swing bolt or a latch bolt.
  • the use of the locking part for an automatic lock with latch bolt on the one hand and hook bolt bolt on the other is of particular importance.
  • the pot fastened to the rear of the closing strip is formed in one piece with the first pot section and the second pot section and, if appropriate, the third pot section, i.e. a uniform pot is realized which only has a plurality of pot sections arranged one above the other, with a partition wall possibly being provided between the pot sections.
  • the third pot section i.e. a uniform pot is realized which only has a plurality of pot sections arranged one above the other, with a partition wall possibly being provided between the pot sections.
  • 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.
  • a pot can also be used in which the individual pot sections are formed by several separate pots, ie several individual pots are fastened to the back of the locking bar with the multiple openings, which form the said pot sections.
  • the receiving pot is made as a separate component, which is attached to the back of the locking bar, z. B. by means of screw connections, rivet connections, clips or clamp connections or the like.
  • the locking strip is particularly preferably designed as a sheet metal part, e.g. B. as a flat sheet or angle sheet with a U-shaped or L-shaped cross-section.
  • the back of it with screws, rivets or the like attached pot can be made of metal, z. B. as a die-cast part.
  • the pot can also be made of plastic.
  • the subject matter of the invention is also the receptacle according to the invention for such a closing part arrangement, i. H. the receiving pot described is also independently placed under protection and it can be combined with a basically known locking strip.
  • the latch bolt 7 has a bolt tip 7a and a beveled actuating edge 7b and it is loaded with a latch spring 13 in the direction of an extended locking position. in the in 2 In the partially extended unlocking position shown, the latch bolt 7 protrudes by an unlocking dimension from the lock housing or over the forend 6 .
  • the latch bolt 7 or the lock chain 14 of the additional locking mechanism is held in the illustrated unlocking position by a blocking element 9 .
  • the swivel bolt 8 is provided, which is retracted in this unlocking position. If the door is now opened starting from the in 2 shown unlocked closed, 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 moves out again by the spring load. In this position, the blocking element 9 for the automatic locking of the locking unit is actuated in such a way that the latch bolt 7 or the lock chain 14 is released, so that the latch bolt 7 is automatically transferred into the extended locking position.
  • the swivel bolt 8 is also transferred to the locking position, but with a time delay, because in the automatic lock it is provided that the swivel bolt 8 is only transferred to the swiveled-out locking position when the door leaf has reached the closed position when the latch bolt 7 reaches or passes a partially extended limit position, in which the latch bolt 7 protrudes by a limit from the lock housing 5 or over the forend 6, which is greater than the unlocking dimension in the unlocked position is.
  • the self-locking is triggered magnetically in the illustrated embodiment, in that the blocking element 9 is actuated by a magnet 10 arranged on the frame side. Alternatively, however, a fundamentally known mechanical triggering of the self-locking can also take place. At the in 2 Castle shown is an example of an embodiment that z. B. in the DE 10 2017 105 125 A1 is described.
  • Such a locking part arrangement 2 consists, in a manner known in principle, of a locking strip 11 on the one hand and a receiving pot 12 fastened to the rear of the locking strip on the other hand.
  • separate locking part assemblies 2 can be used and attached to the frame side for the individual locks of an espagnolette lock.
  • the locking strip 11 has 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 swivel bolt 8 on the other.
  • the closing bar in the embodiment has a third opening 17 for another locking element, e.g. B. for a bolt latch.
  • the receiving cup 12 has cup sections corresponding to the individual openings 15, 16, 17, ie at least one first cup section 18 and at least one second cup section 19 and optionally also a third cup section 20.
  • the first cup section 18 is assigned to the first opening 15 and for the Engagement of the spring-loaded latch bolt 7 determined.
  • the second pot section 19 is assigned to the second opening 16 and is intended for the pivot bolt 8 to engage.
  • the swivel bolt 8 engages behind the back of the locking bar 11 in the locking position.
  • the invention is particularly concerned with the design of the first pot section 18, which is specially designed for engaging the latch bolt 7. This results from 3 and from a comparative view of 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.
  • the receiving pot 12 is dimensioned in the prior art so that there is sufficient play for proper immersion without touching the wall.
  • the latch bolt 7 can immerse into the pot without contact if it is in the optimum mounting position.
  • FIG. 4A to 4E in combination with 3 the inventive design of the receiving pot, in which in particular the bolt tip 7a of the latch bolt 7 facing, front pot inner wall 21 is particularly adapted to the situation, with the representation in the Figures 4A to 4E refers to the first pot section 18 associated with the latch bolt 7 .
  • the front inner wall of the pot 21 is designed in such a way that the latch bolt dips into the pot up to a first immersion depth without contact, which enables the swivel bolt 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 pot inner wall 21 is present.
  • the inner wall 21 of the pot is oriented obliquely to the central axis M of the pot in the exemplary embodiment, so that the receiving pot 12 has a first immersion region that tapers in the direction of immersion up to a first pot depth T1 and an adjoining and likewise tapering second immersion region from the first pot depth T1 to to the bottom of the pot T2, so that the latch bolt dips into the pot without contact up to a first immersion depth in the first immersion region and the latch bolt in the second immersion region bears against the inner wall of the pot from a second immersion depth.
  • the first immersion area tapers by a maximum of 30% from the upper width B0 at the top edge of the pot T0 to an intermediate width B1 at the first pot depth T1.
  • 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.
  • the front wall is consequently oriented obliquely, preferably in two different areas, i. H. first an upper area with a relatively flat slope based on the central axis M, d. H. in the figures in relation to the vertical, and an adjoining lower area with a steeper incline or incline, d. H. in the lower area of the pot, the pot tapers more sharply, so that the bolt 7 comes to rest against the pot wall or front wall 21 there.
  • the pot is formed essentially symmetrically, ie the rear wall 22 of the pot is also formed obliquely in the same or a similar manner.
  • the invention also includes embodiments in which the rear wall 22 (which is shown on the left in each of the figures) is designed in a conventional manner, ie the rear wall according to FIG Figures 4A to 4E could also be designed as the rear wall 22, which in the Figures 5A to 5E is shown.
  • the configuration 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 .
  • latch bolt 7 and swivel bolt 8 in the additional lock only the first pot section and the second pot section are used.
  • the receptacle can be used universally, e.g. B. also for an espagnolette lock from the prior art, in which two bolt bolts and between them a hook bolt bolt 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 portion 19 can be provided for a pivot bolt.
  • a partition wall 23 is provided between the second cup section 19 and the third cup section 20, while no partition wall is provided between the first cup section 18 and the second cup section 19, since in this area the pivot bolt 8 pushes the web 24 between the first opening 15 and the second opening 16 of the closing part 11 must engage behind.
