Description

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

[0002] In practice, such espagnolette locks are used for double-leaf doors in order to lock the passive leaf using the espagnolette bar even when the active leaf is open.

[0003] A corresponding espagnolette lock is known from EP 2 749 721 A1. The espagnolette lock has a control slide that can be moved parallel to a forend and a retracting slide for an espagnolette bar. Upon actuation of the control slide, the retracting slide is driven to retract the espagnolette bar.

[0004] A shoot bolt lock is also known from DE 10 2017 208 721 A1. The shoot bolt lock has a pivot lever mounted rotatably in the lock housing, which is provided with a pin. The pin of the pivot lever engages in a slotted guide of a retracting slide for a shoot bolt bar, which can be moved parallel to a forend. When the shoot bolt lock is operated using a lock follower, the pivot lever is rotated, causing the shoot bolt bar to retract by a specific stroke. The stroke value is fixed and cannot be changed.

[0005] Another espagnolette lock is known from DE 102 09 575 A1. The espagnolette lock has a pivoting lever mounted rotatably in the lock housing, the free end of which engages between two angled extensions of a retracting slide for an espagnolette bar, which can be moved parallel to a forend. When the espagnolette lock is operated using a lock follower, the pivoting lever is rotated, causing the espagnolette bar to retract by a specific stroke. The stroke value is fixed and cannot be changed.

[0006] DE 10 2016 118 112 A1 discloses a shoot-bolt lock with two shoot-bolt rods, which are driven by linear gearing on the retracting slide and gears of different diameters. This document provides gears of different diameters to increase the stroke of the shoot-bolt rods. The disadvantage of this approach is that increasing the stroke requires a design change or replacement of the components of the lock mechanism.

[0007] The present invention is based on the object of providing a deadbolt lock with a simple design and suitable for various doors. In particular, the deadbolt lock should be suitable for use with various accessories, especially different switch locks.

[0008] This object is achieved according to the invention by a deadbolt lock having the features of claim 1.

[0009] According to the invention, a shoot bolt lock for a passive leaf of a double-leaf door is proposed, comprising a shoot bolt rod and a retracting slide connected thereto, and a pivotably mounted reversing lever that can be actuated either by a motor or via a lock nut, which is connected to the retracting slide in order to retract or extend the shoot bolt rod by a specific stroke. It is essential that the reversing lever is connected to the retracting slide via a guide pin that engages in a slotted guide of the retracting slide, wherein the guide pin on the reversing lever can be fixed in at least two positions or can be pivoted or displaced between at least two positions in order to adjust the stroke of the shoot bolt rod.

[0010] In particular, it is provided that the bell crank has at least two spaced-apart positions at which the guide pin can be fixed and / or connected to the bell crank in order to adjust the stroke of the deadbolt rod. Furthermore, the guide pin can be pivotably mounted on the bell crank between at least two positions in order to adjust the stroke of the deadbolt rod. Furthermore, the guide pin can be displaceably mounted on the bell crank between at least two positions in order to adjust the stroke of the deadbolt rod. Furthermore, the guide pin can be displaceably mounted on the bell crank between at least two positions in order to adjust the stroke of the deadbolt rod.

[0011] Preferably, the at least two positions are spaced apart from one another. The effective lever travel of the bell crank can be adjusted or set by the distance between the positions.

[0012] The stroke is the distance by which the espagnolette bar is moved. An adjustable stroke makes it possible to increase or decrease the distance by which the espagnolette bar is moved. This allows, for example, a greater stroke of the espagnolette bar to be used on doors with a large rebate gap while still achieving a secure locking effect. On the other hand, a smaller stroke can be used on doors with a small rebate gap.

[0013] A further advantage of the variable stroke is the ability to use different accessories, such as switch locks, especially latch locks. Different switch locks and latch locks are available on the market, each requiring a different travel of the espagnolette rod. By adjusting the espagnolette rod's travel, adaptation to a corresponding accessory can be achieved easily.

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

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

[0016] In particular, it can be provided to fix the guide pin in a specific position on the bell crank. For example, by screwing, locking, or a positive-locking connection to the bell crank. By fixing the guide pin, the selected stroke of the drive rod is determined according to the position of the guide pin on the bell crank and cannot be subsequently changed.

[0017] Advantageously, the guide pin on the reversing lever can be designed to be adjustable between the at least two positions. For example, a slider can be provided to move the guide pin along the reversing lever. Alternatively, a lever can also be provided to pivot the guide pin on the reversing lever between two positions. Furthermore, the reversing lever can have various spaced-apart receptacles for the guide pin, in order to selectively position the guide pin in one of these receptacles and thus adjust a corresponding stroke.

[0018] The adjustment of the drive rod stroke or the positioning of the guide pin on the bell crank at a specific position can, for example, be done at the factory. Because the guide pin can be easily adjusted between at least two positions, the stroke can also be adjusted during assembly in the field. For example, an opening or flap can be provided in the lock housing of the espagnolette lock, e.g. in the lock cover and / or in the lock base, which makes the guide pin accessible from the outside so that it can be moved between at least two positions. Once the espagnolette lock has been installed in the passive leaf, this opening is no longer accessible, thus preventing tampering.

[0019] In one embodiment, more than two different positions can be provided. For example, three, four, or five positions can be provided in order to be able to adjust the stroke of the espagnolette rod accordingly. In particular, the guide pin on the bell crank can be continuously adjusted within a certain range, whereby a continuous adjustment of the stroke of the espagnolette rod can be achieved. For example, it can be provided that the stroke of the espagnolette rod can be adjusted in a range between 8 mm and 24 mm. Preferably, it can be provided that the stroke of the espagnolette rod can be adjusted in a range between 10 mm and 22 mm. Most preferably, it can also be provided that the stroke of the espagnolette rod can be adjusted in a range between 12 mm and 18 mm.Discrete values ​​can also be selected, for example, one discrete position sets the travel of the espagnolette rod to 12 mm and the second discrete position sets the travel of the espagnolette rod to 18 mm. Of course, other discrete positions are also conceivable, with which the travel of the espagnolette rod 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.

[0020] In one embodiment, the bell crank can be designed as a two-armed pivot lever or as a two-armed bell crank such that the first arm of the bell crank supports the guide pin, and the second arm of the bell crank can be actuated by a motor or via the lock follower to retract or extend the espagnolette bar. This has the advantage that one and the same component both reverses the movement within the espagnolette lock and adjusts the travel distance, namely the stroke of the espagnolette bar.

[0021] In particular, it is provided that the travel of the espagnolette bar refers to the upper espagnolette bar. The espagnolette lock can be designed with a single upper espagnolette bar. Alternatively, the espagnolette lock can also have two espagnolette bars, namely an upper espagnolette bar and a lower espagnolette bar, whereby the adjustment of the travel can refer either only to the upper espagnolette bar, only to the lower espagnolette bar, or to both espagnolette bars simultaneously.

[0022] To reduce the actuation forces during locking and unlocking, the guide pin can be provided with a rotating roller mounted in the guide rail of the retractable slide. In particular, the guide rail of the retractable slide has an elongated hole, which can be designed as a straight or curved elongated hole. In particular, the guide pin is guided in this elongated hole of the guide rail by engaging one end of the guide pin in the guide rail. By providing a rotating roller at this location, friction is reduced accordingly, thus reducing the forces required for actuation.

[0023] In an advantageous embodiment, it can be provided that the guide pin is held on a roller carrier, and that the roller carrier has a locking screw by means of which the roller carrier is screwed to the bell crank. The roller carrier enables easy handling of the guide pin, which simplifies the adjustment of the stroke of the espagnolette rod, and also results in stable mounting of the guide pin on the bell crank. By integrating the locking screw into the roller carrier, the number of interventions required to adjust the guide pin is reduced. In particular, only a single component, namely the roller carrier which has the guide pin, needs to be adjusted in order to set the stroke of the espagnolette rod. A further advantage is that no component needs to be replaced when adjusting the stroke of the espagnolette rod.

[0024] In a preferred embodiment, the bell crank can 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 espagnolette rod. The openings can be designed as recesses or through holes that accommodate the guide pin or are penetrated by the guide pin. The guide pin can be additionally mechanically secured to the bell crank through the openings, for example, by the bell crank additionally fixing and / or holding the guide pin mechanically by means of the positive engagement of the guide pin in the openings.

[0025] In one embodiment, it can preferably be provided that the roller carrier holds the guide pin, and the roller carrier is positively received in one of the recesses of the bell crank. This allows the guide pin to be held with particularly precise fit and free of play. In particular, the roller holder has an outer contour that engages positively in one of the recesses. In particular, the roller holder is adapted to the shape of the recesses in such a way that the outer contour of the roller holder can engage positively in each of the two recesses.

[0026] In particular, it can be provided that the bell crank has an elongated hole through which the guide pin passes, and wherein the guide pin can be displaced along the elongated hole and 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.

[0027] In a preferred embodiment, the rotating roller of the guide pin and the head of the locking screw can be arranged on opposite sides of the bell crank. This has been shown to save installation space and thus allow the espagnolette lock to be constructed more compactly.

[0028] In a preferred embodiment, it can be provided that the locking screw defines a pivot axis about which the guide pin can be pivoted between the at least two positions. In particular, the guide pin can be pivoted about the locking screw in the manner of a lever in order to adjust the stroke of the espagnolette rod between the at least two positions. For this purpose, the locking screw can be loosened far enough that the guide pin can be removed from the slotted guide and / or the openings in the pivot lever and / or the receptacles in the pivot lever, then pivoted into the new position and, in this new position, brought back into engagement with the openings and / or the receptacles and / or the slotted guide and is then fixed in this new position via the locking screw.

[0029] In particular, it can be provided that the drive bolt rod is designed as a first drive bolt rod or as a top locking device, and a second drive bolt rod is provided as a bottom locking device, which is connected to a second retraction slide.

[0030] The second retracting slide can be pivotally connected to the second arm of the bell crank. This has the advantage that the bell crank automatically reverses the movement, so that the lower and upper deadbolts move in opposite directions. For example, when unlocking, both deadbolts are retracted into the housing of the deadbolt lock, and when locking, they are extended from the housing of the deadbolt lock.

[0031] In an advantageous embodiment, a spring drive can be provided, and the espagnolette bar, or both espagnolette bars, are retracted by motor or manually operated by the lock follower while charging the spring drive. During extension, they are extended with the assistance of the spring drive. The advantage here is that the spring drive assists in locking the espagnolette lock, thus ensuring secure locking of the inactive leaf.

[0032] In particular, the inventive concept also includes a locking device for a double-leaf door, comprising a passive leaf and a moving leaf, wherein the passive leaf has a shoot bolt lock according to one of the preceding embodiments and the moving leaf has a panic lock, and the shoot bolt lock has a bolt ejector and / or a latch ejector in order to unlock a bolt and / or a latch of the panic lock.

[0033] The espagnolette lock according to the invention is intended for use with double-leaf doors. The active leaf, or active wing, can be unlocked when the inactive leaf, or passive wing, is opened. For this purpose, the espagnolette lock can be equipped with corresponding bolt slides and / or latch slides to unlock the locking elements of the active wing lock. This has the advantage that in the event of an emergency opening of the double-leaf door, only one leaf, namely the inactive leaf, needs to be operated to open both leaves of the double-leaf door. A further advantage is that the active leaf can be opened while the inactive leaf remains locked by means of the espagnolette lock and the espagnolette rods. This provides the advantage of convenient operation of the double-leaf door and, in an emergency, the possibility of rapid escape through the double-leaf door.

[0034] The espagnolette lock according to the invention can preferably also be used in emergency exits to enable rapid escape in the event of an emergency or panic. The espagnolette lock can be designed as a manual espagnolette lock that is operated manually. In another embodiment, the espagnolette lock can also be designed as a motor-driven espagnolette lock, i.e., the espagnolette bolts and / or bolt ejectors can be actuated by a motor. Combined manual and motor-driven operation of the espagnolette lock is also possible.

[0035] In particular, the espagnolette lock can be DIN EN 179 in order to be able to use it for fire and smoke protection doors. Alternatively and / or additionally, the espagnolette lock according to the invention can also be used according to DIN EN 1125 to be able to work on panic doors.

[0036] Further embodiments and examples of the espagnolette lock according to the invention are shown in the figures and described below. They show: Fig. 1: a locking device on a double-leaf door comprising a drive bolt lock according to the invention; Fig. 2a-c: an embodiment of the drive bolt lock according to the invention with 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 espagnolette lock according to the invention in locked position with 12 mm stroke; Fig. 5a-c: the espagnolette lock according to the Figures 4a-c in 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 bell crank with roller carrier.

[0037] The figures illustrate exemplary embodiments of the espagnolette lock 2 according to the invention. These are not intended to be limiting. In the figures, components with equivalent functions are provided with the same reference symbols. A person skilled in the art can combine the various embodiments shown with one another, based on their technical skills, within the scope of protection defined by the claims, without departing from the spirit of the invention.

[0038] The Fig. 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 a moving leaf 15. The fixed leaf 14 is pivotally mounted on a door frame 12 of the double-leaf door 11 via hinges 131, 132.

[0039] Likewise, the active leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via door hinges 133, 134.

[0040] The active leaf 15 has a panic lock 16, which is operated via a door handle 17. The panic lock 16 is designed as a self-locking panic lock and has an automatically extending bolt and a latch. The inventive espagnolette lock 2 is accommodated in the passive leaf 14. The espagnolette lock 2 has an upper espagnolette bar 21 and a lower espagnolette bar 24. In the illustration of the Fig. 1the espagnolette lock 2 is locked, i.e. the two espagnolette bars 21 and 24 are extended and lock the inactive leaf 14 to the door frame 12 and the floor. The espagnolette lock 2 can be manually unlocked using a lock nut 27. The espagnolette lock 2 has a latch receiving space and a bolt receiving space 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 using the espagnolette lock 2 via the latch slide or bolt slide. This means that when the espagnolette lock 2 is unlocked, the panic lock 16 is unlocked first, so that the active leaf 15 can be opened, whereby the inactive leaf 14 is still locked via the espagnolette bars. The inactive leaf 14 can only be opened when the espagnolette lock 2 is completely unlocked.

[0041] In the Figures 2a, 2b and 2cAn embodiment of the espagnolette lock according to the invention is shown in the locked position. In the example shown, Figures 2a to 2c The espagnolette lock 2 is set to a stroke of 18 mm. The espagnolette lock 2 has a lock housing 28 and a forend 29. A lock follower 27 is rotatably received in the lock housing 28 for manually unlocking the espagnolette lock 2. Furthermore, an electric motor 33 with a spindle drive 34 is housed in the lock case 28 for motor-actuating the espagnolette lock 2, in particular for unlocking it. Furthermore, the espagnolette lock 2 comprises a spring drive having two coil springs 261 and 262. These coil springs are each designed as return springs 261 and 262 and assist in relocking the espagnolette lock 2.

[0042] On its upper side, the espagnolette lock 2 has a first upper espagnolette bar 21. This is connected to an upper retracting slide 22 guided within the lock case 28. On its underside, the espagnolette lock 2 has a second lower espagnolette bar 24. This is connected to a lower retracting slide 25.

[0043] Furthermore, the espagnolette lock 2 comprises 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 on the front side behind the face plate 29 there is a latch receiving space and a bolt receiving space in each case in order to accommodate a latch or a bolt of an active sash lock.

[0044] The two feed slides 22 and 25 are driven by a reversing lever 35. For this purpose, the lower feed slide 25 is connected to the reversing lever 35 by a pin 36. The upper feed slide 22 has, as shown in Fig. 2c As can be seen, it has a link guide 23 into which a guide pin 41 of the reversing lever 35 engages.

[0045] The reversing lever 35 is rotatably mounted in the lock case 28. In the Figures 6 and 7An enlargement of the reversing lever 35 is shown, from which the pivot point 353 is visible. The reversing lever 35 can be operated by motor and / or manually. The reversing lever 35 pivots clockwise, as indicated by the arrow in the area of ​​the pivot point, and thereby moves the upper retraction slide 22 downwards and the lower retraction slide 25 upwards. Accordingly, the connected espagnolette bars 21 and 24 move towards each other, i.e., into the interior of the lock case 28. The corresponding unlocked position of the espagnolette lock 2 is shown in the Figures 3a to 3c visible.

[0046] The bell crank 35 is designed as a two-armed bell crank 35. It has a first arm 351 and a second arm 352, which are Figures 6 and 7 At the front of the reversing lever 35, a roller carrier 4 is mounted, which has the guide pin 41. This is shown, for example, in the Fig. 2b or 3b The structure of the roller carrier is shown in the Figures 8 and 9 The roller carrier 4 supports the guide pin 41, the free end of which carries a rotatable roller 411. Furthermore, the roller carrier 4 holds a locking screw 42, by means of which the roller carrier 4 can be fastened to the reversing lever 35.

[0047] The bell crank 35 has on its first arm 351 two openings 37 and 38 which are inserted into the Figures 6 and 7 The guide pin 41 can be attached to the bell crank 35 in two different positions. In the outer position as shown in the illustration of the Figures 2a to 2c and 3a to 3c the guide pin 41 is received in the opening 38, as shown in the Fig. 6This is the outer opening 38, which extends the effective travel of the reversing lever 35. This increases the distance by which the retraction slide 22 is retracted into the lock housing 28. In the 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 bell crank 35 when the deadbolt lock 2 is unlocked can be seen from the Figures 3b and 3c visible.

[0048] In the Fig. 3a The motor-unlocked position of the espagnolette lock with 18 mm stroke is shown. Fig. 3a It can be seen that the spindle drive 34 has moved upwards and in doing so has moved the reversing lever 35 in relation to the illustration in Fig. 2aclockwise. Via the pin 36, the second arm 352 of the reversing lever 35 takes the lower retracting slide 25 with it and retracts it together with the lower espagnolette rod 24 into the lock housing 28. At the same time, via the guide pin 41, which engages in the slot 23 of the upper retracting slide 22, the first arm 351 of the reversing lever 35 retracts the upper retracting slide 22 and thus the upper espagnolette rod 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 in the direction of the face plate 29 in order to force a bolt and a latch out of the lock case 28 of the espagnolette lock 2. In the Figures 3a, 3b and 3c In the position shown, the espagnolette lock 2 is completely unlocked, ie a corresponding passive leaf 14 can be opened.

[0049] In the Figures 2b and 2c3b and 3c, respectively, the bell crank 35 with its connection to the upper retraction slide 22 and the upper drive bolt rod 21 is shown cut away. Figures 2b and 3b show a three-dimensional front view and the Figures 2c and 3c the cut-out view from behind.

[0050] 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 There, the guide pin 41 engages the first opening 37 of the reversing lever 35. This shortens the effective lever of the reversing lever 35 or the first lever arm 351.

[0051] The espagnolette lock 2 corresponding to this variant adjusted to the shortened stroke is in the Figures 4a to 4c shown in locked position. The Fig. 4a corresponds to the representation of the espagnolette lock 2 according to Fig. 2awith the only difference that the roller carrier 4 is fixed to the bell crank 35 in a first position, which corresponds to a shortened stroke. The corresponding unlocked position of the deadbolt lock 2 is shown in the Figures 5a to 5c These figures also fully correspond to the Figures 3a to 3c with the only 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 reversing lever 35. This position of the guide pin 41 corresponds to a shortened stroke 51 corresponding to a stroke of 12 mm. This is Fig. 5a visible.

[0052] The Figure 10shows an embodiment in which the roller carrier 4 holds the guide pin 41 and sits positively in an opening 38 or recess 38 of the reversing lever 35. The roller carrier 4 is screwed to the reversing lever 35 via the locking screw 42. The roller carrier 4 has an outer contour that is positively held in the opening 38. The roller carrier extends through the opening 38. As a result, the guide pin 41 is held on the reversing lever 35 in a mechanically stable and play-free manner. Analogously, the roller carrier 4 can also be held in the second opening 37 or recess 37 of the reversing lever 35.

[0053] To adjust the stroke, the roller carrier 4 is loosened using the locking screw 42 on the bell crank 35 and moved to the other position, where it is then secured again using the locking screw 42. This allows the stroke of the espagnolette bar 21 to be easily adjusted without the need to install other components or make any structural changes to the espagnolette lock 2.
