Description

[0001] The invention relates to a locking bolt lock according to the features of the preamble of claim 1.

[0002] In practice, such bolt locks are used for double-leaf doors to lock the fixed leaf even when the active leaf is open, using a bolt rod.

[0003] A corresponding multi-point locking system is known from EP 2 749 721 A1. The multi-point locking system has a control slide that is movable parallel to a faceplate and a retraction slide for a multi-point locking bar, wherein, when the control slide is actuated, the retraction slide is driven to retract the multi-point locking bar.

[0004] A multi-point locking system is also known from DE 10 2017 208 721 A1. This multi-point locking system has a pivot lever rotatably mounted in the lock housing, which is provided with a pin. The pin of the pivot lever engages in a cam slot of a retractable slide for a multi-point locking bar, which is slidable parallel to a faceplate. When the multi-point locking system is actuated using a lock follower, the pivot lever is rotated, causing the multi-point locking bar to retract by a specific stroke. The stroke is fixed and cannot be changed.

[0005] Another multi-point locking system is known from DE 102 09 575 A1. This multi-point locking system features a pivot lever rotatably mounted in the lock housing, the free end of which engages between two angled projections of a retraction slide that is slidable parallel to a faceplate for a multi-point locking bar. When the multi-point locking system is actuated using a lock follower, the pivot lever is rotated, causing the multi-point locking bar to retract by a specific stroke. The stroke value is fixed and cannot be changed.

[0006] German patent DE 10 2016 118 112 A1 discloses a bolt lock with two bolt rods driven by a linear toothing on the draw slide and gears of different diameters. This document provides gears with different diameters to increase the stroke of the bolt rods. A disadvantage of this design is that increasing the stroke necessitates a modification of the lock mechanism or a replacement of its components.

[0007] The present invention aims to provide a multi-point locking system that is structurally simple and suitable for use on various doors. In particular, the multi-point locking system should be compatible with different accessories, especially different switch locks.

[0008] This problem is solved according to the invention by a bolt lock with the features of claim 1.

[0009] According to the invention, a bolt lock for a fixed leaf of a double-leaf door is proposed, comprising a bolt rod and a retraction slide connected thereto, and a pivotally mounted deflection lever, which can be actuated by a motor or via a lock follower, and which is connected to the retraction slide in order to retract or extend the bolt rod by a defined stroke. Essentially, the deflection lever is connected to the retraction slide via a guide pin that engages in a cam guide of the retraction slide, wherein the guide pin on the deflection lever can be fixed in at least two positions or pivoted or displaced between at least two positions in order to adjust the stroke of the bolt rod.

[0010] In particular, the deflection lever is provided to have at least two spaced-apart positions at which the guide pin can be fixed and / or connected to the deflection lever in order to adjust the stroke of the locking bar. Furthermore, the guide pin can be pivotably mounted on the deflection lever between at least two positions to adjust the stroke of the locking bar. Additionally, the guide pin can be movably mounted on the deflection lever between at least two positions to adjust the stroke of the locking bar. Finally, the guide pin can be slidably mounted on the deflection lever between at least two positions to adjust the stroke of the locking bar.

[0011] Preferably, the at least two positions are spaced apart from each other. The effective lever travel of the deflection lever can be adjusted or set by changing the distance between the positions.

[0012] The stroke refers to the distance the locking bolt is moved. An adjustable stroke allows this distance to be increased or decreased. This enables, for example, a larger stroke of the locking bolt to be used for doors with a large rebate gap, while still ensuring secure locking. Conversely, a smaller stroke can be used for doors with a small rebate gap.

[0013] A further advantage of the variable stroke is that different accessories, such as latch locks, especially deadbolt locks, can be used. Various latch locks are available on the market, each requiring a different stroke of the bolt rod. Adjusting the bolt rod stroke allows for easy adaptation to the specific accessory.

[0014] In particular, a latch lock can be mounted at the upper end of the upper locking bar in the door leaf. Preferably, the latch lock interacts with a door opener mounted on the frame. The latch lock can have a cylindrical housing and be mounted, in particular screwed, into a bore or channel in the door leaf, especially into the channel of the upper locking bar.

[0015] In particular, the guide pin on the deflection lever is adjustable between two positions. Preferably, the lever travel of the deflection lever is determined by the guide pin mounted on the deflection lever. By extending the effective arm of the deflection lever, a greater adjustment travel and thus a greater stroke of the locking bar is achieved when the deflection lever is moved. By varying the guide pin on the deflection lever between at least two positions, the adjustment travel can therefore be set to at least two predetermined positions or two predetermined values. This adjustment can be implemented with respect to discrete positions or continuously within a range between two end positions.

[0016] In particular, it may be possible to fix the guide pin in a specific position on the deflection lever. This can be achieved, for example, by screwing it in place, locking it into place, or using a positive-locking mechanism on the deflection lever. By fixing the guide pin, the selected stroke of the connecting rod is determined according to the position of the guide pin on the deflection lever and cannot be changed subsequently.

[0017] Advantageously, the guide pin on the deflection lever can be designed to be adjustable between at least two positions. For example, a slide can be provided to move the guide pin along the deflection lever. Alternatively, a lever can be provided to pivot the guide pin on the deflection lever between two positions. Furthermore, the deflection lever can have several spaced-apart receptacles for the guide pin, allowing the guide pin to be selectively positioned in one of these receptacles and thus setting a corresponding stroke. The adjustment of the connecting rod stroke or the positioning of the guide pin on the deflection lever at a specific position can, for example, be done at the factory. Due to the easy adjustability of the guide pin between the at least two positions, the stroke can also be adjusted during field assembly.For example, the lock housing of the multi-point locking system, such as in the lock top and / or bottom, may have an opening or flap that allows access to the guide pin from the outside, enabling it to be moved between at least two positions. Once the multi-point locking system is installed in the fixed leaf, this opening is no longer accessible, thus preventing tampering.

[0018] In one embodiment, more than two different positions can be provided. For example, three, four, or five positions can be provided to adjust the stroke of the locking bar accordingly. In particular, the guide pin on the deflection lever can be continuously adjusted within a certain range, thereby achieving stepless adjustment of the locking bar's stroke. For example, the stroke of the locking bar can be adjusted within a range of 8 mm to 24 mm. Preferably, the stroke of the locking bar can be adjusted within a range of 10 mm to 22 mm. Most preferably, the stroke of the locking bar can also be adjusted within a range of 12 mm to 18 mm.Discrete values ​​can also be selected, for example, one discrete position that sets the stroke of the locking bolt to 12 mm and a second discrete position that sets the stroke of the locking bolt to 18 mm. Of course, other discrete positions are also conceivable, with which the stroke of the locking bolt is set to a lower value, for example 10 mm and / or 8 mm, or to a higher value, for example 20 mm, 22 mm, etc.

[0019] In one embodiment, the deflection lever can be designed as a two-armed pivot lever or as a two-armed deflection lever such that the first arm of the deflection lever supports the guide pin and the second arm of the deflection lever can be actuated by a motor or via the lock follower to retract or extend the locking bolt. This has the advantage that one and the same component effects both a reversal of movement within the locking bolt and the adjustment of the travel distance, namely the stroke of the locking bolt.

[0020] In particular, it is provided that the stroke of the locking bolt refers to the upper locking bolt. The locking bolt can be designed with a single upper locking bolt. Alternatively, the locking bolt can also have two locking bolts, namely an upper locking bolt and a lower locking bolt, whereby the adjustment of the stroke can refer either only to the upper locking bolt, or only to the lower locking bolt, or to both locking bolts simultaneously.

[0021] To reduce the actuation forces during locking and unlocking, the guide pin can be provided with a rotatable roller mounted in the cam guide of the feed slide. Specifically, the cam guide of the feed slide has an elongated slot, which can be either straight or curved. The guide pin is guided in this elongated slot by engaging it with one end. By providing a rotatable roller at this point, friction is reduced, thus decreasing the actuation forces required.

[0022] In an advantageous embodiment, the guide pin can be mounted on a roller support, and the roller support has a locking screw by means of which the roller support is screwed to the deflection lever. The roller support allows for particularly easy handling of the guide pin, which simplifies adjusting the stroke of the locking bar and also provides stable mounting of the guide pin on the deflection lever. Integrating the locking screw into the roller support also reduces the number of adjustments required to move the guide pin. Specifically, only a single component, namely the roller support which holds the guide pin, needs to be adjusted to set the stroke of the locking bar. A further advantage is that no component needs to be replaced when adjusting the stroke of the locking bar.

[0023] In a preferred embodiment, the deflection lever may have at least two spaced-apart round openings to define the at least two positions, and the guide pin extends through one of the round openings to determine a specific stroke of the locking bar. The openings may be designed as recesses or through-holes that receive the guide pin or are penetrated by the guide pin. The openings may also provide additional mechanical security for the guide pin on the deflection lever, for example, by the deflection lever mechanically fixing and / or holding the guide pin in the openings by means of a positive fit.

[0024] Preferably, in one embodiment, the roller holder can be configured to hold the guide pin and to be positively engaged in one of the recesses of the deflection lever. This allows the guide pin to be held with a particularly precise and play-free fit. In particular, the roller holder has an outer contour that positively engages in one of the recesses. The roller holder is specifically adapted to the shape of the recesses such that its outer contour can positively engage in each of the two recesses.

[0025] In particular, it can be provided that the deflection lever has an elongated hole through which the guide pin penetrates, and wherein the guide pin is displaceable along the elongated hole and can be fixed at any position by the locking screw in order to determine a specific stroke of the drive bolt rod, preferably that the elongated hole is designed as a curved elongated hole.

[0026] In a preferred embodiment, the rotatable roller of the guide pin and the head of the locking screw can be arranged on opposite sides of the deflection lever. This has been shown to save installation space and thus allow for a more compact design of the bolt lock.

[0027] In a preferred embodiment, the locking screw can define a pivot axis about which the guide pin can pivot between the at least two positions. In particular, the guide pin can be pivoted about the locking screw like a lever to adjust the stroke of the locking bar between the at least two positions. For this purpose, the locking screw can be loosened sufficiently to remove the guide pin from the cam guide and / or the openings of the pivot lever and / or the receptacles of the pivot lever, then pivoted into the new position, and in this new position re-engaged with the openings and / or the receptacles and / or the cam guide, and then fixed in this new position by means of the locking screw.

[0028] In particular, it may be provided that the locking bar is designed as a first locking bar or as a top lock, and a second locking bar is provided as a bottom lock, which is connected to a second insertion slide.

[0029] It can be provided that the second insertion slide is rotatably connected to the second arm of the deflection lever. This offers the advantage that the deflection lever automatically reverses the movement, so that the lower and upper locking bolts move in opposite directions. For example, when unlocking, both locking bolts are retracted into the housing of the locking bolt lock, and when locking, they are extended out of the housing.

[0030] In an advantageous embodiment, a spring drive can be provided, and the locking bolt rod, or the two locking bolt rods, can be retracted by a motor or manually via the lock follower, charging the spring drive, and extended by the spring drive. The advantage here is that the spring drive assists in locking the locking bolt lock, thus ensuring secure locking of the fixed leaf.

[0031] In particular, the inventive concept also includes a locking device for a double-leaf door, comprising a fixed leaf and an active leaf, wherein the fixed leaf has a multi-point locking system according to one of the preceding embodiments and the active leaf has a panic lock, and the multi-point locking system has a bolt ejector and / or a latch ejector to unlock a bolt and / or a latch of the panic lock.

[0032] One application of the inventive bolt lock is intended for double-leaf doors. The active leaf (or "active" leaf) can be unlocked when the passive leaf (or "inactive" leaf) is opened. For this purpose, the bolt lock can have corresponding bolt slides and / or latch slides to unlock the locking elements of the active leaf lock. This has the advantage that, in an emergency opening of the double-leaf door, only the operation of a single leaf, namely the passive leaf, is sufficient to open both leaves of the double-leaf door. A further advantage is that the active leaf can be opened while the passive leaf remains locked by the bolt rods of the bolt lock. This results in the advantage of convenient operation of the double-leaf door and, in an emergency, the possibility of a quick escape through the double-leaf door.

[0033] The bolt lock according to the invention can preferably also be used in emergency exits to enable rapid escape in emergencies or panic situations. The bolt lock can be designed as a manual bolt lock, which is operated manually. In another embodiment, the bolt lock can also be designed as a motor-operated bolt lock, i.e., the bolts and / or bolt ejectors can be actuated by a motor. A combined manual and motor-operated operation of the bolt lock is also possible.

[0034] In particular, the multi-point locking system can be designed in accordance with DIN EN 179 for use in fire and smoke control doors. Alternatively and / or additionally, the multi-point locking system according to the invention can also be designed in accordance with DIN EN 1125 for use in panic doors.

[0035] The figures show further embodiments and examples of the bolt lock according to the invention, which are described below. These include: Fig. 1: A locking device on a double-leaf door comprising a multi-point locking system according to the invention; Fig. 2a-c: An embodiment of the multi-point locking system according to the invention with an 18 mm stroke in the locked position; Fig. 3a-c: The embodiment from the Fig. 2a-c in unlocked position; Fig. 4a-c: an embodiment of the bolt lock according to the invention in locked position with a 12 mm stroke; Fig. 5a-c: the bolt lock according to the Figures 4a-c in the unlocked position; Fig. 6: the deflection lever in position 18 mm; Fig. 7: the deflection lever in position 12 mm; Fig. 8: a schematic representation of the roller carrier; Fig. 9: a section through the roller carrier according to Fig. 8 ; Fig. 10: a section through the deflection lever with roller carrier.

[0036] The figures show exemplary embodiments of the bolt lock 2 according to the invention. These are not to be understood as limiting. In the figures, components that function identically are designated with the same reference symbols. A person skilled in the art can, using their practical skills, combine the different embodiments shown within the scope of protection defined by the claims without departing from the inventive concept.

[0037] The Fig. 1 Figure 1 shows a schematic representation of a locking device 1 on a double-leaf door 11. The double-leaf door 11 has a fixed leaf 14 and an active leaf 15. The fixed leaf 14 is pivotally mounted on a door frame 12 of the double-leaf door 11 via hinges 131, 132. Similarly, the active leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via hinges 133, 134.

[0038] The active leaf 15 has a panic lock 16, which can be operated via a door handle 17. The panic lock 16 is designed as a self-locking panic lock and has a self-extending bolt and a latch. The inert leaf 14 houses the multi-point locking system 2 according to the invention. The multi-point locking system 2 has an upper multi-point bolt 21 and a lower multi-point bolt 24. In the illustration of the Fig. 1The multi-point locking system 2 is locked, meaning that the two locking bolts 21 and 24 are extended and lock the fixed leaf 14 to the door frame 12 and the floor. The multi-point locking system 2 can be manually unlocked via a lock follower 27. The multi-point locking system 2 has a latch receptacle and a bolt receptacle into which the locking elements of the panic lock 16, i.e., the latch and the bolt, can engage. The panic lock 16 can be unlocked by means of the multi-point locking system 2 via latch slides and bolt slides, respectively. This means that when the multi-point locking system 2 is unlocked, the panic lock 16 is unlocked first, allowing the active leaf 15 to be opened, while the fixed leaf 14 remains locked by the locking bolts. Only when the multi-point locking system 2 is fully unlocked can the fixed leaf 14 then be opened.

[0039] In the Figures 2a, 2b and 2cAn embodiment of the inventive bolt lock in the locked position is shown. In the example shown, the Figures 2a to 2c The bolt lock 2 is set to a stroke of 18 mm. The bolt lock 2 has a lock housing 28 and a faceplate 29. A lock follower 27 is rotatably mounted in the lock housing 28 to manually unlock the bolt lock 2. Furthermore, an electric motor 33 with a spindle drive 34 is mounted in the lock housing 28 to actuate the bolt lock 2, in particular to unlock it. The bolt lock 2 also includes a spring drive comprising two coil springs 261 and 262. These coil springs are each designed as return springs 261 and 262 and assist in relocking the bolt lock 2.

[0040] On its upper side, the multi-point locking system 2 has a first upper locking bar 21. This is connected to an upper guide slide 22 guided within the lock case 28. On its underside, the multi-point locking system 2 has a second lower locking bar 24. This is connected to a lower guide slide 25.

[0041] Furthermore, the bolt lock 2 includes in its housing a bolt slide 31 and a latch slide 32. In the Fig. 2a In the locked position shown, both the latch slide 32 and the bolt slide 31 are retracted into the lock housing 28, so that a latch receiving space and a bolt receiving space are each provided on the front side behind the faceplate 29 in order to receive a latch or a bolt of an active wing lock.

[0042] The two feed slides 22 and 25 are driven via a deflection lever 35. For this purpose, the lower feed slide 25 is connected to the deflection lever 35 via a pin 36. The upper feed slide 22 has, as shown in Fig. 2c It can be seen that a cam guide 23 is installed, into which a guide pin 41 of the deflection lever 35 engages.

[0043] The deflection lever 35 is rotatably mounted in the lock case 28. In the Figures 6 and 7An enlargement of the deflection lever 35 is shown, from which the pivot point 353 is visible. The deflection lever 35 can be operated by motor and / or manually. In doing so, the deflection lever 35 pivots clockwise, as indicated by the arrow shown in the area of ​​the pivot point, thereby moving the upper insertion slide 22 downwards and the lower insertion slide 25 upwards. Accordingly, the connected locking bolt rods 21 and 24 move towards each other, i.e., into the interior of the lock case 28. The corresponding unlocked position of the locking bolt 2 is shown in the Figures 3a to 3c visible.

[0044] The deflection lever 35 is designed as a two-armed deflection lever 35. It has a first arm 351 and a second arm 352, which are located in the Figures 6 and 7 are shown. A roller carrier 4, which has the guide pin 41, is mounted on the front of the deflection lever 35. This is shown, for example, in the Fig. 2b or 3b The structure of the roller carrier is shown. Figures 8 and 9 The roller support 4 supports the guide pin 41, the free end of which carries a rotatable roller 411. Furthermore, the roller support 4 holds a locking screw 42, by means of which the roller support 4 can be attached to the deflection lever 35.

[0045] The deflection lever 35 has two openings 37 and 38 on its first arm 351, which are located in the Figures 6 and 7 The figures are shown enlarged. The guide pin 41 can be attached to the deflection lever 35 in two different positions. In the outer position, as shown in the illustration... Figures 2a to 2c and 3a to 3c The guide pin 41 is received in the opening 38, as shown in the illustration. Fig. 6This refers to the outer opening 38, which extends the effective travel of the deflection lever 35. This increases the distance by which the retraction slide 22 is drawn into the lock housing 28. Fig. 3a The corresponding stroke 52 is shown, which corresponds to a stroke of 18 mm when the deadbolt lock 2 is fully unlocked. The corresponding position of the deflection lever 35 when the deadbolt lock 2 is unlocked can be seen from the Figures 3b and 3c visible.

[0046] In the Fig. 3a The motor-released position of the deadbolt lock with an 18 mm stroke is shown. Fig. 3a It is evident that the spindle drive 34 has moved upwards and thereby moved the deflection lever 35 opposite the illustration in Fig. 2ahas pivoted clockwise. Via the pin 36, the second arm 352 of the deflecting lever 35 takes the lower draw-in slide 25 with it and pulls it, together with the lower locking bolt 24, into the lock housing 28. Simultaneously, via the guide pin 41, which engages in the cam 23 of the upper draw-in slide 22, the first arm 351 of the deflecting lever 35 pulls the upper draw-in slide 22, and thus the upper locking bolt 21, into the lock housing 28. At the same time, the bolt slide 31 and the latch slide 32 are actuated, i.e., moved out of the lock case 28 towards the faceplate 29, to push a bolt and a latch out of the lock case 28 of the multi-point locking system 2. In the Figures 3a, 3b and 3c In the position shown, the drive bolt lock 2 is fully unlocked, i.e., a corresponding fixed leaf 14 can be opened.

[0047] In the Figures 2b and 2cIn figures 3b and 3c, the deflection lever 35 with its connection to the upper feed slide 22 and the upper drive bolt rod 21 is shown in a cutaway view. Figures 2b and 3b They show a three-dimensional front view and the Figures 2c and 3c the cut-out view from behind.

[0048] To change the stroke of the drive bolt rod 21, the roller carrier 4 is moved to the other position with the guide pin 41. This is shown in the Fig. 7 The guide pin 41 engages in the first opening 37 of the deflection lever 35. This shortens the effective lever arm of the deflection lever 35, or the first lever arm 351.

[0049] The bolt lock 2, corresponding to this variant set to the shortened stroke, is in the Figures 4a to 4c shown in the locked position. Fig. 4a This corresponds to the representation of the bolt lock 2 according to Fig. 2awith the sole difference that the roller carrier 4 is fixed to the deflection lever 35 in a first position which corresponds to a shortened stroke. The corresponding unlocked position of the drive bolt lock 2 is in the Figures 5a to 5c depicted. These figures also fully correspond to the Figures 3a to 3c with the sole difference that the roller carrier 4 is in its first position, in which the guide pin 41 is positioned in the first opening 37 of the deflection lever 35. This position of the guide pin 41 corresponds to a shortened stroke 51, corresponding to a stroke of 12 mm. This is due to Fig. 5a visible.

[0050] The Figure 10Figure 1 shows an embodiment in which the roller carrier 4 holds the guide pin 41 and is positively engaged in an opening 38 or recess 38 of the deflection lever 35. The roller carrier 4 is screwed to the deflection lever 35 via the locking screw 42. The roller carrier 4 has an outer contour that is positively engaged in the opening 38. The roller carrier extends through the opening 38. This ensures that the guide pin 41 is held mechanically stable and without play on the deflection lever 35. Similarly, the roller carrier 4 can also be held in the second opening 37 or recess 37 of the deflection lever 35.

[0051] To adjust the stroke, the roller carrier 4 is loosened on the deflection lever 35 using the locking screw 42, moved to the other position, and then fixed there again using the locking screw 42. This allows for a simple adjustment of the stroke of the locking bolt rod 21 without the need for other components or any design modifications to the locking bolt lock 2. Reference symbol list
