Description

[0001] The invention relates to a deadbolt lock for locking and unlocking a passive leaf of a double-leaf door according to the features of the preamble of claim 1.

[0002] In practice, espagnolette locks are known that can be operated mechanically or by electric motor. For example, document DE 10 2016 108 706 A1 describes a motorized espagnolette lock that can be unlocked manually or by motor.

[0003] Die EP 2 749 721 B1 describes a motorized espagnolette lock with a motorized drive and latch slide. The motorized drive is essential for this espagnolette lock, meaning that the espagnolette lock always requires an appropriate power supply.

[0004] Die EP 3 543 439 A1 also shows a motorized espagnolette lock without a latch ejector. This espagnolette lock also always requires a power supply and, moreover, has limited applications because it has no means of unlocking a latch.

[0005] Furthermore, espagnolette locks that utilize a door opener are known in practice. A corresponding espagnolette lock is described in DE 10 2006 038 610 A1.

[0006] The invention is based on the object of creating a versatile espagnolette lock with a bolt ejector and at least one espagnolette bar. In particular, the espagnolette lock should be usable either with a bolt ejector alone or optionally with a bolt ejector and a latch ejector. Preferably, an electric door opener should be used instead of the latch ejector. In particular, the espagnolette lock should be retrofittable and / or upgradeable with a motorized drive. Furthermore, the espagnolette lock should preferably be suitable for use with different backsets.

[0007] This object is achieved according to the invention by a deadbolt lock having the features of claim 1.

[0008] According to the invention, a shoot bolt lock for locking and unlocking a passive leaf of a double-leaf door is proposed, comprising a lock housing with a faceplate, wherein a retraction slide for a shoot bolt rod and a bolt slide are mounted in the lock housing, and a slide plate is mounted so as to be linearly displaceable and a lock nut with a nut lever is rotatably mounted in order to manually unlock the shoot bolt lock, wherein a bolt of an active leaf lock can be pushed out of the lock housing by means of the bolt slide.It is essential that the lock housing has at least two installation spaces, wherein a motor module comprising a motor for motor-driven unlocking of the espagnolette lock can be installed or retrofitted optionally in a first installation space, and / or a latch slide module comprising a latch ejector can be installed or retrofitted optionally in a second installation space in order to force a latch of an active leaf lock out of the lock housing when unlocking, or that a door opener can be installed in the second installation space.

[0009] One advantage is that the espagnolette lock has a lock housing in which mechanical lock components are housed in such a way that manual operation of the espagnolette lock is possible, such that a passive leaf is locked or unlocked via an espagnolette rod and a locking slide. Universal usability of the espagnolette lock is achieved by the fact that the lock housing can be retrofitted, for example, by upgrading the lock housing with a motor module to enable motorized unlocking of the espagnolette lock. The motor module with the motor is inserted into a first receiving space of the lock housing.

[0010] One advantage is that the motor module with the drive motor is optional, meaning it can be used selectively, so that the espagnolette lock can be used either as a purely manual or mechanical espagnolette lock, or as a combined mechanical and motor-operated espagnolette lock.

[0011] Furthermore, the lock housing comprises at least one second installation space in which a latch ejector can be optionally installed. This makes it possible to operate the espagnolette lock either with just a latch ejector or with a latch ejector and a latch ejector. This allows the espagnolette lock according to the invention to be optimally adapted to the respective application. The costs required for manufacturing the espagnolette lock are also reduced, since only those components of the espagnolette lock that are necessary to fulfill the respective function need to be used. Furthermore, a door opener can be installed in the second installation space. The door opener can be installed in the second installation space instead of a latch ejector. Alternatively, a latch ejector present in the second installation space can be removed and a door opener installed.

[0012] In particular, the term “installation space” refers to a space within the lock housing into which components, modules, or structural units for retrofitting or upgrading the espagnolette lock can be accommodated or installed. Preferably, “accommodated or installable” means that the components, modules, or structural units can be mechanically fastened in an installation space and connected to gear components and / or electronic components of the lock mechanism or espagnolette lock. In particular, the components are installed or accommodated in such a way that they are in an operative or drive connection with the lock mechanism. This means that a latch slide or door opener subsequently installed in the installation space can also be operated by manually operating the lock follower.

[0013] In particular, the espagnolette lock can also be used without the additional modules, i.e., without the motor module and / or without the latch module and / or without a door opener. This allows for the production of a particularly cost-effective espagnolette lock. Should the application area of ​​the espagnolette lock be expanded subsequently, the espagnolette lock can be adapted by upgrading or retrofitting the motor module in the first installation space or by upgrading or retrofitting a latch module or a door opener in the second installation space. The same applies in reverse, of course, i.e., the espagnolette lock can be used with a motor module or latch module and subsequently retrofitted by removing the motor module or latch module.

[0014] In particular, the motor module can be designed such that it can be installed in the first installation space in such a way that it is mechanically fastened in the first installation space and an operative connection is established to an electronic component and / or gear component of the espagnolette lock or the lock mechanism.

[0015] In particular, the latch slide module can be designed such that it can be installed in the second installation space such that it is mechanically fastened in the second installation space and an operative connection is established to an electronic component and / or gear component of the espagnolette lock or the lock mechanism.

[0016] The gear component of the espagnolette lock or the lock mechanism can be understood as a lever and / or a gear wheel and / or a rack and / or a guide rail and / or a slide plate.

[0017] The electronic component of the deadbolt lock or the lock mechanism can be understood as a sensor and / or a control device.

[0018] Components or modules or assemblies for retrofitting or upgrading may include a motor module, and / or a sensor module, and / or a control module, and / or a trap ejector module, and / or a digital interface module.

[0019] Preferably, the espagnolette lock can be designed with a single espagnolette bar, for example, an upper espagnolette bar. Alternatively, the espagnolette lock can also have two espagnolette bars, for example, an upper espagnolette bar and a lower espagnolette bar.

[0020] The locked position of the espagnolette lock is understood in particular to mean a position in which the espagnolette bar or the two espagnolette bars are extended upwards and downwards out of the lock housing in such a way that the upper espagnolette bar engages in a locking receptacle on the door frame and the lower espagnolette bar engages in a locking receptacle on the floor of a door.

[0021] The unlocked position of the espagnolette lock means in particular that the two espagnolette bars are completely retracted into the lock housing so that the espagnolette bars no longer interact with a locking receptacle and the passive leaf can be opened.

[0022] A particular advantage is that during upgrades and / or retrofitting, the components are installed in the same lock housing as the espagnolette lock. This means that the dimensions of the lock housing remain unchanged, even if the espagnolette lock is upgraded with a motorized drive, a latch ejector, or a door opener. Advantageously, the components, modules, or assemblies for upgrades are housed within the lock housing, i.e., they are enclosed by the lock housing and thus protected.

[0023] In particular, the lock housing of a shoot-bolt lock is understood to be a housing in which the components of the shoot-bolt lock are housed. The lock housing preferably has recesses in the area of ​​the face plate that allow the passage of locking elements, such as the lock bolt and / or latch of an active leaf lock. Furthermore, the lock housing can have recesses on its upper and lower narrow sides for the passage of shoot-bolt rods.

[0024] In particular, a slide plate is understood to be a predominantly flat or plate-like component that can be moved linearly within the lock housing, preferably parallel to the faceplate. In particular, the slide plate connects several movable elements of the espagnolette lock to one another. For this purpose, the slide plate can, for example, have one or more guides. Additionally or alternatively, the slide plate can have one or more pins and / or rollers, each of which establishes a connection to a movable element of the lock mechanism. Likewise, one or more mechanical stops can be formed on the slide plate to interact with pins or rollers of movable elements of the espagnolette lock.

[0025] In one embodiment, it can be provided that the motor module comprises a motor and a motor output, wherein the motor output acts on the slide plate in order to move it into an unlocking position by motor.

[0026] In particular, it can be provided that the motor gear pushes the slide plate in the unlocking direction for unlocking by means of a one-sided contact, whereby the one-sided contact is open in the unlocking direction. The one-sided contact between the motor gear and the slide plate results in a particularly simple upgrade or retrofit, since only the motor with its output has to be brought into contact with the slide plate or a pin of the slide plate from below and the slide plate can then be moved in the unlocking direction by pressing on one side. Removing the motor module or the motor from the installation space is also easy in this way, since the motor or the motor module can be simply removed without the laborious process of breaking a mechanical connection between the slide plate and the motor gear.

[0027] Preferably, the motor can be designed as a linear motor or have a spindle drive to move the slide plate in an unlocking direction. Sensors can interact with the linear motor and / or the spindle drive and / or the slide plate, in particular, they can be arranged on the linear motor or the spindle drive or the slide plate to detect a locked position and / or a center position and / or an unlocked position.

[0028] In an advantageous embodiment, the lock housing can be provided with an installation space for installing or retrofitting a sensor board module in order to electronically detect different positions of the espagnolette lock or different positions of components of the espagnolette lock. The installation space can, for example, run parallel to the lock ceiling or the lock floor. This allows a flat, plate-shaped sensor module to be accommodated in a space-saving manner. In particular, the sensor module is designed as a flat circuit board on which various sensors are positioned such that, after installation of the sensor module in the lock housing, they are already correctly positioned relative to the components to be detected. The sensors can, for example, be sensors that detect a locking position and / or an unlocking position of the espagnolette lock.Alternatively or additionally, sensors can also be used that detect, for example, the actuation of the follower and / or the position of the espagnolette rods and / or the position of the latch ejector and / or bolt ejector. Alternatively or additionally, the sensors can also include a bolt sensor and / or a latch sensor to detect the engagement of a bolt or latch of an active leaf lock in the lock housing. The sensors can be designed as a button and / or a light barrier and / or a Hall sensor.

[0029] Preferably, the lock housing can be provided with an installation space for installing or retrofitting a control module or a control device to electronically control the espagnolette lock, in particular to control a motor drive and / or to evaluate sensors. The control module or control device can be used within the lock housing to both control the motor's power and implement logic, for example, using a microprocessor, to evaluate sensors of the espagnolette lock. For example, the control device or control module can detect a fault condition and / or proper operation of the espagnolette lock based on sensor signals.In particular, a control module or control device is understood to be an electronic device that features a power interface for controlling the motor and a data interface for evaluating sensors. The control device can communicate with higher-level control units, such as an access control system and / or a higher-level escape and rescue route control center, via a communication interface.

[0030] Preferably, it can be provided that the lock housing has an installation space for installing or retrofitting a bolt contact and / or an installation space for installing or retrofitting a latch contact in order to detect engagement of a bolt of an active latch lock and / or a latch of an active latch lock in the lock housing.

[0031] In an advantageous embodiment, it can be provided that an electric door opener can be installed or retrofitted into the second installation space instead of a latch slide module or a latch ejector, or that it can be replaced with a latch slide module or a latch ejector. In particular, it can be provided that the electric door opener is a standard door opener with standard dimensions. For this purpose, the lock housing can have corresponding receptacles for inserting the door opener into the lock housing and securing it, for example, by screwing.

[0032] In order to enable both electrical and mechanical actuation, it is provided, in particular in one embodiment, that the electric door opener is designed as a mechanically and electrically switchable, in particular unlockable, door opener, and that an unlocking slider which can be moved parallel to the face plate is mounted in the lock housing in order to mechanically switch, in particular unlock, the door opener via an unlocking button.

[0033] Preferably, it can be provided that one feed slide, in particular the upper feed slide, is designed as an unlocking slide, in particular has two mutually spaced-apart unlocking buttons for actuating the unlocking button, or that the two feed slides are each designed as an unlocking slide, in particular that the upper feed slide has an unlocking button, preferably for DIN left, and that the lower feed slide has an unlocking button, preferably for DIN right.

[0034] In particular, the electric door opener is electrically operated. The door opener can be designed as a fail-lock door opener or a fail-lock door opener. In addition to the electrical release, the door opener has an unlocking button on its rear. The door opener can be unlocked by pressing the unlocking button. The door opener has a door opener latch, which can be designed, in particular, as a pivoting latch. When the door opener is locked, this latch is blocked from pivoting. When the door opener is unlocked, this pivoting latch is released, meaning it can pivot freely around a longitudinal axis.

[0035] In an advantageous embodiment, it can be provided that the electric door opener can be installed in the second installation space both in a 0° installation position and rotated by 180° in order to lock or unlock left-hinged doors or right-hinged doors.

[0036] In order to be able to operate doors hinged on the right as well as on the left without making any structural changes to the espagnolette lock, a preferred embodiment can provide for the release slide to have two spaced-apart release buttons in order to mechanically switch, in particular to unlock, the door opener both in a 0° installation position and in a 180° installation position using the release buttons, or for the two retraction slides to each have an release button in order to mechanically switch, in particular to unlock, the door opener both in a 0° installation position and in a 180° installation position using the release buttons.

[0037] In a preferred embodiment, it can be provided that in at least one installation space, at least one of the installed modules takes on the function of a lock pin in order to mechanically stabilize the lock housing. A lock housing has a lock cover and a lock base. Lock pins are normally used distributed over the lock housing to enable force transmission between the lock cover and lock base and thus stabilize the lock housing. Advantageously, it can be provided that the modules installed in the lock housing are designed to be mechanically stable in the respective installation spaces so that these modules take on the function of a lock pin. This enables a mechanically stable construction of the lock housing and reduces the number of required components because lock pins can be dispensed with.

[0038] Advantageously, it can be provided that the lock housing of the espagnolette lock has uniform dimensions, in particular dimensions according to an industry standard or an official standard of a standards authority. In particular, one and the same housing with one and the same dimensions provides an espagnolette lock which can either be operated purely mechanically, or can be operated purely mechanically and has sensors, or can be operated mechanically and by a motor. The advantage is that the dimensions of the lock housing remain the same at every equipment level and reworking of the doors in which the espagnolette lock is installed is not necessary. In particular, it can be provided that the lock housing has dimensions which, up to a backset of 35 mm to 100 mm, do not exceed 165 mm in height, and do not exceed 16 mm in width.The depth can be between 50 mm and 134 mm depending on the door size, in particular the lock housing has dimensions according to DIN 18250.

[0039] Advantageously, the lock housing can be adapted to different backset sizes by using a latch slide module with a longer latch slide stem and a deadbolt slide with a longer deadbolt slide stem for a larger backset. This is made possible, in particular, by arranging the lock mechanism in the rear part of the lock housing. The front part toward the faceplate of the lock housing can be extended by extending the rear part of the latch ejector or latch slide, i.e., the latch slide stem, and the rear part of the deadbolt slide or deadbolt ejector, i.e., the deadbolt ejector stem. This makes it possible to adapt the espagnolette lock to different backset sizes.

[0040] In one embodiment, it can be provided that a second retraction slide is accommodated in the lock housing, in particular a lower retraction slide, in addition to the first or upper retraction slide which can be connected to a first or upper drive bolt rod, and the second retraction slide can be connected to a second drive bolt rod.

[0041] The two feed slides can be connected to each other via a two-armed reversing lever.

[0042] In a preferred embodiment, the lower retraction slide or the upper retraction slide can be directly connected to the bell crank via an engagement point in order to pivot the bell crank, in particular to pivot the bell crank during manual unlocking. Advantageously, a direct connection of the retraction slides via the bell crank creates a positive guide for the two retraction slides relative to each other, so that when one of the retraction slides is driven, the other retraction slide is automatically actuated in the opposite direction to unlock the espagnolette lock.

[0043] In particular, a retractable slide is understood to be a component that can be moved linearly within the lock housing, preferably parallel to the faceplate, and which has a connection for a deadbolt. A retractable slide can predominantly be designed as a flat or plate-shaped component.

[0044] In particular, it can be provided that the nut lever has a pin or a roller by means of which it interacts directly with the lower feed slide or the upper feed slide, in that the lower feed slide or the upper feed slide has a slide stop surface for the pin or the roller, such that the nut lever acts on, in particular pushes, the lower feed slide or the upper feed slide into an unlocking position via the pin or the roller during manual unlocking.

[0045] In a preferred embodiment, it can be provided that a two-armed bolt slide lever is rotatably mounted concentrically to the lock nut in the lock housing, the first arm of which interacts with the slide plate via a link pin guided in a link guide of the slide plate, and the second arm of which interacts with the bolt ejector in order to move the latter between an unlocking position pre-closed from the lock housing and a locking position retracted into the lock housing.

[0046] In particular, it can be provided that the second arm of the bolt slide lever actuates the latch ejector via a latch reversing lever to move it between an unlocking position and a locking position. This allows the bolt ejector and the latch ejector to be actuated via the same component, which increases functional reliability and enables a compact design.

[0047] To ensure secure unlocking during manual unlocking using the lock nut, one embodiment can provide the nut lever with a driver for the locking slide lever. This driver engages with the locking slide lever when the lock nut is rotated, moving it into an unlocked position. This allows direct actuation of the locking slide lever during manual unlocking without the need for intermediate gear components. This increases functional reliability and minimizes the number of required components.

[0048] In one embodiment, it can be provided that for motorized unlocking, the motor acts on the slide plate, and that for manual unlocking, the nut lever acts on the lower retraction slide or the upper retraction slide, in particular that the nut lever acts on the lower retraction slide or the upper retraction slide for unlocking in the same direction, in particular the unlocking direction, in which the motor acts on the slide plate for unlocking. In particular, direct actuation via the nut lever is provided, so that no further gear component needs to be moved between the nut lever and the retraction slide. This enables safe unlocking at any time manually via the lock nut and the nut lever.

[0049] In order to facilitate the operation of the espagnolette lock and to increase functional reliability, a preferred embodiment can provide for the lock housing to have a spring drive, and the retraction slide or the two retraction slides and / or the slide plate to be actuated in the unlocking direction by motor or manually by the lock nut while charging the spring drive and to be actuated in the locking direction with the support of the spring drive.

[0050] In particular, it can be provided that the spring drive has two springs, wherein one of the springs acts on the slide plate and the second spring acts on the lower feed slide or the upper feed slide, in particular that the springs are designed as helical springs and / or compression springs.

[0051] The inventive concept also encompasses a locking device for a double-leaf door comprising a fixed leaf and a moving leaf, wherein the fixed leaf has a deadbolt lock according to one of the embodiments described herein. The moving leaf can have an anti-panic lock with a bolt and / or a latch. The deadbolt lock accordingly has a bolt ejector and optionally a latch ejector to unlock the bolt and / or latch of the anti-panic lock of the moving leaf. Unlocking via the deadbolt lock can be manual or, if the deadbolt lock is equipped with a motor drive, manual and / or motorized.

[0052] The espagnolette lock can be designed according to DIN EN 179 for use in fire and smoke doors. Alternatively and / or additionally, the espagnolette lock according to the invention can also be designed according to DIN EN 1125 for use in panic doors.

[0053] Further embodiments and examples of the espagnolette lock according to the invention are shown in the figures and described below.

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.

[0055] 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. Likewise, the moving leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via hinges 133, 134.

[0056] 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 24 and a lower espagnolette bar 25. In the illustration of the Fig. 1 the espagnolette lock 2 is locked, i.e., the two espagnolette rods 24 and 25 are extended and lock the inactive leaf 14 to the door frame 12 and the floor. The espagnolette lock 2 can be manually unlocked via a lock nut 23. Furthermore, the espagnolette lock 2 has a motor, by means of which the espagnolette lock 2 can be unlocked by motor. The connecting cable 18 of the motor 3 or the control device 7 of the motor 3 is guided through the inactive leaf 14 and, by means of a flexible cable transition 19, over the door frame 12. 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 via the latch slide or bolt slide by means of the espagnolette lock 2.When the espagnolette lock 2 is unlocked, the panic lock 16 is unlocked first, allowing the active leaf 15 to be opened, while the inactive leaf 14 is still locked via the espagnolette bars. Only when the espagnolette lock 2 is completely unlocked can the inactive leaf 14 be opened.

[0057] In the Fig. 2 The espagnolette lock 2 is shown schematically in the locked position. The espagnolette lock 2 has a lock housing 21, on the front of which a face plate 22 is arranged. The components of the espagnolette lock 2 are accommodated within the lock housing 21. For clarity, Fig. 2 The lock cover is removed or shown transparently. The espagnolette lock 2 has an upper espagnolette bar 24 and a lower espagnolette bar 25. The espagnolette bars are each connected to the mechanism of the espagnolette lock 2 via retraction slides 241 and 251. The upper retraction slide 241 is connected to the upper espagnolette bar 24. The lower retraction slide 251 is connected to the lower espagnolette bar 25.

[0058] The espagnolette lock 2 comprises a bolt ejector 5 or a bolt slide 5. The bolt slide 5 is mounted horizontally displaceably in the lock housing 21 in order to force a lock bolt of an active leaf lock out of the door lock housing 21 if the espagnolette lock 2 is unlocked.

[0059] In the locked representation of the espagnolette lock 2 according to Fig 2 The two retractable slides 241 and 251, with the attached espagnolette bars 24 and 25, are fully extended from the lock housing 21 to lock a passive leaf. A receiving space is arranged in the lock housing 21 in front of the bolt ejector 5, into which a lock bolt of an active leaf lock can engage.

[0060] A lock follower 23 is rotatably mounted in the lock housing 21. The espagnolette lock 2 can be unlocked manually or mechanically via the lock follower 23. The lock follower 23 is connected to a follower lever 231 in a rotationally fixed manner.

[0061] A two-armed bolt slide lever 28 is pivotally mounted in the lock housing 21 concentrically to the lock nut 23. The bolt slide lever 28 has two interconnected bolt slide arms 281 and 282. The first bolt slide arm 281 is arranged above the lock nut 23. The second bolt slide arm 282 is arranged below the lock nut 23. The lower bolt slide arm 282 cooperates with the bolt ejector 5. When the bolt slide lever 28 is rotated counterclockwise, the bolt ejector 5 is actuated into the unlocked position, i.e. moved towards the forend 22. This allows a lock bolt of an active sash lock to be pushed back, i.e. pushed out of the lock housing 21 of the espagnolette lock 2.

[0062] The lock nut 23 or the nut lever 231 has a driver 232 on its upper side for the bolt slide lever 28. This means that when the lock nut 23 is rotated counterclockwise to unlock the espagnolette lock, the driver 232 comes into contact with the upper bolt slide arm 281 and takes the bolt slide lever 28 with it.

[0063] The espagnolette lock 2 further comprises a spring drive 6. The spring drive 6 has two compression springs 61 and 62. The spring drive 6 is charged when the espagnolette lock 2 is unlocked. When the espagnolette lock 2 is locked, the spring drive 6 assists in moving the espagnolette lock 2 into the locked position. The first compression spring 61 of the spring drive 6 acts on the slide plate 27, and the second compression spring 62 acts on the lower retraction slide 251.

[0064] The slide plate 27 is mounted in the lock housing 21 of the espagnolette lock 2 so that it can move parallel to the face plate. Fig. 2 In the locked position shown, the slide plate 27 is in its lowest position and is held there by the compression spring 61.

[0065] During unlocking, the lock follower 23 is pivoted counterclockwise, causing the follower lever 231 to move upward. The follower lever 231 has a follower roller 233 on its upper side. The follower roller 233 interacts with the lower retracting slide 251 to raise it when the espagnolette lock 2 is unlocked, thereby retracting the lower espagnolette rod 25 into the lock housing 21. Since the lower retracting slide 251 is connected to the upper retracting slide 241 via the reversing lever 26, when the lower retracting slide 251 is retracted into the lock housing 21, the upper retracting slide 241 is automatically retracted as well, thereby unlocking the upper espagnolette rod 24.

[0066] The Fig. 2 shows the espagnolette lock 2 in a small expansion stage as a mechanical espagnolette lock 2 with only one bolt ejector 5 and two espagnolette rods 24, 25. The lock housing 21 comprises several installation spaces 81, 82, 83, 84, 85 for accommodating additional components in order to upgrade or retrofit the espagnolette lock 2. A first installation space 81 is arranged in the rear region of the lock housing 21 and is designed to accommodate a motor module or a motor drive comprising a motor 3 and a motor output 31. Below the first installation space 81, a further installation space 83 is arranged to accommodate a control device 7. The control device 7 can be designed, for example, to control the motor drive 3 and / or to evaluate sensors. A further installation space 82 is formed in the lock housing 21 to accommodate a latch ejector 4.The latch ejector 4 is arranged above the lock follower 23 to force a latch of an active leaf lock out of the lock housing 21 during unlocking. Below the installation space 82, an installation space 85 is arranged for accommodating a latch contact 42. Below the bolt ejector 5, a further installation space 84 is arranged for accommodating a latch contact 51. The engagement of a bolt or latch of an active leaf lock in the lock housing 21 can be detected via the latch contact 51 or latch contact 42.

[0067] Furthermore, a further installation space (not shown) is provided below the lock cover to accommodate a sensor module, for example a circuit board with several sensors 75, 76, 77, 78, 79. Individual components or their positions can be monitored via the sensors 75, 76, 77, 78, 79.

[0068] The components or parts and / or modules that can be accommodated in the individual installation spaces 81, 82, 83, 84, 85 are optional. This means that the deadbolt lock 2 is in the Fig. 2 The illustrated minimal configuration is fully functional as a manual or mechanical espagnolette lock 2. By expanding individual components, such as a motor drive 3 in the installation space 81, and / or sensors 75, 76, 77, 78, 79, or a latch ejector in the second installation space 82, the functionality of the espagnolette lock 2 can be expanded to include additional applications. One advantage of this is that when expanding the espagnolette lock 2, the lock housing 21 does not need to be modified, and the modules, components, or parts intended for expansion are all accommodated within the lock housing 21.

[0069] In the Fig. 3 The deadbolt lock 2 is also shown in a locked position, but opposite to the one shown in Fig. 2 The embodiment shown has been expanded to include various components. A motor drive module comprising a motor 3 and a motor output 31 is arranged in the first receiving space 81. A control device 7 is arranged below the motor drive module 3 in the installation space 83. The control device 7 has a connecting cable 18 to supply the control device 7 and / or the drive module 3 with electrical energy and control signals. Furthermore, a bolt switch contact 51 is accommodated in the installation space 84. The bolt switch contact 51 is connected to the control device 7 and detects the engagement of a bolt of an active sash lock in the bolt receiving space of the espagnolette lock 2. In the upper region of the espagnolette lock 2, a latch contact 42 is accommodated in the installation space 85. The latch contact 42 detects the engagement of a latch of an active sash lock in the latch receiving space of the espagnolette lock 2.

[0070] Furthermore, a sensor circuit board is housed in a further installation space (not shown in the figure) beneath the lock cover of the espagnolette lock 2. The sensor module comprises a circuit board with several sensors 75, 76, 77, 78, 79. A first sensor 75 is designed as a latch ejector sensor. A second sensor 76 is designed as a follower follower sensor and detects actuation of the lock follower 23. Another sensor 77 is designed as a top / bottom locking sensor and detects the locking position of the upper and lower retracting slides 241, 251, respectively. Another sensor 78 is designed as a bolt ejector sensor and detects the position of the bolt ejector 5. Another sensor 79 is designed as a tamper sensor and detects an attempt at tampering from the outside by pressing in the espagnolette bars 25 and 24, respectively.

[0071] The motor 3 has a motor output 31, which is designed as a spindle drive 31. The spindle drive comprises a spindle nut 33 and a spindle 32. When the spindle 32 rotates, the spindle nut 33 is moved up or down along the spindle 32. The spindle nut has two stop surfaces 331 and 332, each of which interacts with a pin of the slide plate 27. As a result, the slide plate 27 is actuated or pushed into the locking position by means of a one-sided contact by the spindle nut 33. Thanks to the one-sided open contact between the stop surfaces 331 and 332 and the pins 271, 272 of the slide plate 27, no complex mechanical connection is necessary to drive the slide plate 27. Furthermore, the motor drive 3 comprises four sensors 71, 72, 73, 74 to detect the position of the motor output 31 or the slide plate 27. The first, lowermost sensor 71 detects the locking position of the motor output 31 orthe slide plate 27. The sensor 72 detects a center position of the slide plate 27 or the motor output 31. The upper sensor 73 detects the unlocked position of the slide plate 27 or the motor output 31. Furthermore, a bolt retraction sensor 74 is provided to detect actuation of the bolt ejector 5 by means of the bolt slide lever 28. The sensors 75, 76, 77, 78, 79 are designed as light barriers that are actuated or passed through by switching flags arranged on the motor output 31. Alternatively or additionally, the sensors 71, 72, 73, 74 can also be designed as Hall sensors and / or mechanical microswitch contacts.

[0072] In the Fig. 4 Another variant of the espagnolette lock 2 is shown schematically in the locked position. The espagnolette lock 2 has, in addition to the Figur 3 The variant shown has a trap ejector 4.

[0073] The espagnolette lock 2 has an upper espagnolette bar 24 and a lower espagnolette bar 25. The espagnolette bars 24, 25 are each connected to the mechanism of the espagnolette lock 2 via retractable slides 241 and 251. The upper retractable slide 241 is connected to the upper espagnolette bar 24. The lower retractable slide 251 is connected to the lower espagnolette bar 25.

[0074] Furthermore, the espagnolette lock 2 comprises a bolt ejector 5 and a latch ejector 4. The latch ejector 4 was inserted into the second installation space 82 and mechanically fastened there and connected to the first arm 281 of the bolt slide lever 28. In the Fig. 4 In the locked position shown, the latch ejector 4, as well as the bolt ejector 5, are retracted into the lock housing 21. This creates a receiving space in front of the latch ejector 4 and the bolt ejector 5, into which a latch or a bolt of an active leaf lock can engage. This allows the espagnolette lock 2 to be locked not only via the espagnolette bars 24, 25, but also via the locking elements, in particular a lock bolt and a lock latch of an active leaf lock.

[0075] Furthermore, the espagnolette lock 2 comprises a motor drive accommodated in the first installation space 81. The motor drive comprises an electric drive motor 3 with a motor output 31, which is designed as a spindle drive. The motor output 31 further comprises a spindle 32 and a spindle nut 33. When the motor is actuated, the spindle nut 33 moves up and down along the spindle 32. The spindle nut 33 has two stop surfaces 331 and 332, each of which interacts with a pin 271, 272 of the slide plate 27. The slide plate 27 is mounted in the lock housing 21 parallel to the face plate 22 for linear displacement and can be actuated by the motor 3 or the spindle drive 31. In the locked position shown, the slide plate 27 is arranged in its lower position. The spindle nut 33 is also arranged in the lower position.

[0076] The positions of the motor output 31 and the slide plate 27 can be detected via the sensors 71, 72, 73, 74.

[0077] Furthermore, the espagnolette lock 2 comprises a spring drive 6 comprising two compression springs 61 and 62. The spring drive 6 is charged when the espagnolette lock is unlocked. When locked, the spring drive 6 acts as a support to move the espagnolette lock 2 into the locked position.

[0078] The bolt slide lever 28 is rotatably mounted concentrically to the lock nut 23 and has two interconnected bolt slide arms. The first bolt slide arm 281 is arranged above the lock nut 23, and the second bolt slide arm 282 is arranged below the lock nut 23. The upper bolt slide arm 281 interacts with the latch slide 4 via a latch deflection lever 41. When the latch ejector 4 is installed in the installation space 82, the latch deflection lever 41 is connected to the first arm 281 of the bolt slide lever 28. The lower bolt slide arm 282 interacts with the latch ejector 5. When the bolt slide lever 28 is turned counterclockwise, both the bolt ejector 5 and the latch ejector 4 are actuated into the unlocked position, ie moved in the direction of the face plate 22.As a result, locking elements of an active wing lock (not shown) which engage in the lock housing 21 of the deadbolt lock 2 can be displaced from the latter into an unlocking position.

[0079] The two feed slides 241, 251 are connected to each other via a reversing lever 26. As can be seen from Figur 11 As can be seen, the lower feed slide 251 is rotatably connected to the reversing lever 26 via the engagement point 254, which is designed as a pivot pin. The reversing lever 26 is designed as a two-armed reversing lever. The engagement point 254 is arranged on the first arm 261 of the reversing lever 26, and a guide pin 265 is provided on the second arm 262 of the reversing lever 26 in order to connect the reversing lever 26 to the first feed slide or the upper feed slide 241 ( Fig. 12 ).

[0080] Furthermore, a control device 7 is accommodated in the third installation space 83 of the lock housing 21. The control device 7 is connected to the motor 3 in order to control it. The control device 7, and thus the motor 3, is electrically connected to a power supply or control center via a connecting cable 18. The control device 7 and the motor 3 are supplied with electrical energy and control signals via this cable 18.

[0081] The control device 7 is connected to several sensors that are arranged in the lock housing 21 and interact with various components of the lock mechanism, for example, to detect their position. Thus, several sensors 71, 72, 73, 74 are provided in the area of ​​the slide plate 27 to detect the positions of the slide plate 27. A first sensor 71 is designed as a locking sensor to detect the locking position. A second sensor 72 is designed as a center position sensor to detect the center position. A third sensor 73 is designed as an unlocking sensor to detect the unlocking position. A sensor 74 is designed as a bolt retraction sensor. The sensors 71, 72, 73, 74 are each designed as a light barrier and are passed through by a flag on the motor nut. Alternatively, the sensors 71, 72, 73, 74 can also be designed as buttons or as Hall sensors.

[0082] For example, a control signal can be received via control device 7 to unlock the espagnolette lock. Control device 7 then controls motor 3, starting from the locked position. Motor 3 moves slide plate 27 parallel to faceplate 22 until it reaches the unlocked position. This is detected by unlocking sensor 73 and reported to control device 7. Control device 7 then switches off motor 3. Similarly, using control device 7 and center position sensor 72, espagnolette lock 2 can be motor-driven to the center position.

[0083] Furthermore, the espagnolette lock includes a latch contact 42 to detect the position of a latch of an active leaf lock. The latch contact 42 was installed in the installation space 85 ( Fig. 2 ) and secured there. When the active leaf is closed and the deadbolt lock 2 is locked, the latch of the active leaf lock engages in the latch receiving space of the lock housing 21, thereby actuating the latch contact 42. The control device 7 is connected to the latch contact 42 and evaluates its signal to detect the latch of the active leaf lock. The signal can also be sent via the control device 7 via cable 18 to a higher-level control center, for example, an access control device.

[0084] Furthermore, the espagnolette lock 2 comprises a bolt contact 51 to detect the position of a bolt of an active leaf lock. The bolt contact 51 was installed in the installation space 84 ( Fig. 2 ) and secured there. When the active leaf is closed and the shoot bolt lock 2 is locked, and the active leaf lock is locked, the bolt of an active leaf lock engages the bolt receiving space of the lock housing 21, thereby actuating the bolt contact 51. The control device 7 is connected to the bolt contact 51 and evaluates its signal to detect the bolt of the active leaf lock. The signal can also be sent via the control device 7 via cable 18 to a higher-level control center, for example, an access control device or an alarm system.

[0085] In the Fig. 5 the deadbolt lock 2 is in accordance with Fig. 4 shown in a motor-driven unlocked position. To motor-driven unlock the espagnolette lock 2, the motor 3 is actuated so that the spindle nut 33, as shown in Fig. 5 shown, is moved upwards along the spindle 32 and thereby takes the slide plate 27 along with it. The driving takes place via the first stop surface 331 and second stop surface 332, which are each connected to the two stop pins 271, 272, which, for example, in Fig. 10 are shown, are in contact and thus take the slide plate 27 with them during the upward movement along the spindle 32. In doing so, the slide plate 27 leaves the switching range of the locking sensor 71, moves into the unlocked position, and there actuates the unlocking sensor 73.

[0086] The locking slide lever 28 is guided with its first locking slide arm 281 or the upper locking slide arm 281 in the guide rail 273 of the slide plate 27. As a result of the movement of the slide plate 27 parallel to the face plate 22 upwards according to Fig. 5 , the bolt slide lever 28 is pivoted counterclockwise by the guide rail 273. Consequently, the lower or second bolt slide arm 282 pushes the bolt ejector 5 into the Fig. 3 The unlocking position shown in FIG. 1 is shown in FIG. 2, in which the end of the bolt slide 5 projects beyond the face plate 22. The latch ejector 4 is also moved out of the lock housing 21 into the position shown in FIG. 1 via the reversing lever 41, which is connected to the first bolt slide arm 281. Fig. 5 The lock nut 23 remains in the neutral position.

[0087] The Figur 6 shows the deadbolt lock according to the Fig. 5 in a middle position. Starting from the Fig. 4 In the locked position shown, the control device 7 actuated the motor 3 to move the slide plate 27 into the position corresponding to the center position. To do this, the slide plate 27 is moved upwards parallel to the face plate via the motor output 31 until the center position sensor 72 detects that the center position has been reached. The locking pivot lever 28 is rotated counterclockwise by the guide rail 273 and actuates both the bolt ejector 5 and the latch ejector 4 into the unlocked position. In the unlocked position, the head of the bolt ejector 5 and the head of the latch ejector 4 are at the level of the face plate 22 or protrude slightly beyond it. A locking element of an active leaf lock received in the lock housing 21 is thereby forced out of the lock housing. A lock bolt or a lock latch of an active leaf lock is thus disengaged from the lock housing 21.

[0088] At the same time, the slide plate 27 actuates the relay lever 26 via the slide roller 274. However, due to the very flat control curve 263, the relay lever 26 is only pivoted slightly. In this range of movement, the control curve 263 runs almost parallel to the unlocking direction, so that the relay lever 26 is only rotated relatively little or at a low speed. As a result, the retracting slides 241 and 251 are each only retracted a short distance into the lock housing 21. This distance is dimensioned such that the two espagnolette bars 24 and 25 are still engaged with their receptacles in the door frame 12 and the floor, respectively, in the center position and are therefore in a locked position. This means that in the center position, the inactive leaf 14 is locked via the espagnolette bars 24 and 25, but the active leaf 15 or moving leaf 15 can be opened.For example, a daytime switch can be implemented in which the active leaf 15 is freely accessible.

[0089] In the middle position, the slide plate 27 is in a position between its two end positions. The first end position is the locked position of the slide plate 27 according to Fig. 4 The second end position is the motorized unlocked position according to Fig. 5 . The middle position according to Fig. 6 is specifically intended for motorized unlocking only. During manual unlocking via the lock follower 23, the espagnolette bars 24 and 25, the bolt ejector 5, and the latch ejector 4 are actuated directly into their unlocked positions, without any intermediate center position.

[0090] In the Fig. 7 The espagnolette lock 2 is shown in another variant, in which Fig. 2 In a non-illustrated installation space parallel to the lock cover, a sensor module is arranged and in the area of ​​the second installation space 82, instead of a latch ejector 4, an electric door opener 44 is arranged. The latch ejector module 4 and the latch contact 42 are arranged according to the Figuren 4 , 5 and 6 The variants shown can be replaced with the door opener 44. The electric door opener 44 is a mechanically and / or electrically operated door opener 44. The door opener 44 has a release button 45 on its rear side. The door opener 44 can be mechanically unlocked by pressing the release button 45.

[0091] The door opener 44 has a lockable and releasable pivoting latch. When the door opener 44 is unlocked, the latch can be freely pivoted. When the door opener 44 is locked, the pivoting latch is fixed, meaning it cannot be actuated. The door opener 44 can be actuated electrically or mechanically, meaning it can be unlocked or locked electrically or mechanically.

[0092] For the mechanical unlocking of the door opener 44, the lower retraction slide 251 has an actuating bar or unlocking button 241a ( Figur 11 ). This actuating bar or release button 241a actuates the door opener in the Fig. 7 shown installation position. This corresponds to a DIN left position for DIN left-hinged doors.

[0093] In the Fig. 8 The deadbolt lock 2 is in accordance with Fig. 7 The door opener 44 is shown with the door opener 44 installed in a 180° position. The release button 45 is located at the top in this position. This corresponds to the installation position for right-hinged DIN doors.

[0094] For the mechanical unlocking of the door opener 44, the upper retraction slide 241 has an actuating bar or unlocking button 241b, as shown in Fig. 12 can be clearly seen. To mechanically unlock the door opener 44, the actuating bar or unlocking button 241b actuates the unlocking button 45.

[0095] The Fig. 8 The illustrated installation position of the door opener 44 corresponds to DIN right, ie for DIN right-hinged door leaves.

[0096] In Fig. 9 another variant of the espagnolette lock 2 is shown with a backset increased to 100 mm. The lock housing 21 is extended forwards towards the forend 22. In the rear area of ​​the forend 22, the previously described lock mechanism of the espagnolette lock 2 is arranged unchanged. The change required for a larger backset consists in the bolt ejector 5 and latch ejector 4 being each extended at their rear. This means that the stem of the bolt ejector 5 and the stem of the latch ejector 4 are extended accordingly in order to achieve the larger backset. The associated contacts, i.e. the bolt switching contact 51 and the latch switching contact 42, are also extended at their rear. Further adjustments to the components are not necessary.

[0097] The Fig. 9 is shown as an example for a backset of 100 mm. In contrast to the variant in Fig. 9 A smaller backset, for example, 80 mm or 65 mm, can also be realized. Larger backsets, for example, 120 mm, are also conceivable. In this case, the front of the lock housing 21 is adjusted according to the desired backset, the stem of the bolt slide 5 and the stem of the latch slide 4 are extended accordingly, and the appropriate sensors, i.e., the bolt switch contact 51 and the latch switch contact 42, are inserted.

[0098] In Fig. 10 The principle of unlocking the drive bolt rods 24, 25 when the slide plate 27 is actuated by a motor is shown. As shown in Fig. 10 As can be seen, the slide plate 27 has a slide roller 274, which interacts with a control cam 263 of the reversing lever 26. The reversing lever 26 is rotatably mounted about the pivot point 264. The control cam 263 is arranged on the first arm 261 of the reversing lever 26. As a result of the movement of the slide plate 27 upwards along the arrow shown, the slide roller 274 pushes the first arm of the reversing lever 26 upwards, whereupon the lower retraction slide 251, which is connected to the first arm 261 via the engagement point 254, also moves upwards, so that the lower espagnolette rod 25 is inserted into the lock housing 21 of the espagnolette lock 2. At the same time, the second arm 262 of the reversing lever 26 moves downwards, taking with it the upper feed slide 241, which is connected to the reversing lever 26 or its second arm 262 via the guide pin 265. The connection of the lower feed slide 251 to the reversing lever 26 is described in detail in Fig. 11 The connection of the upper feed slide 241 to the reversing lever 26 is shown in detail in the Fig. 12 shown. During unlocking, the bell crank 26 is pivoted along the arrow shown around the pivot point 264.

[0099] In Fig. 10 In the upper area of ​​the slide plate 27, the guide rail 273 is shown, in which the guide pin 283 of the locking slide lever 28 is guided. The guide rail 273 has two differently oriented guide rail areas 275, 276. The first guide rail area 275 runs obliquely to the unlocking direction in order to pivot the locking slide lever 28 between its locked position and the unlocked position. When the slide plate 27 moves, the guide pin 283 runs along the guide rail 273. The first link section 275 runs obliquely to the direction of movement of the slide plate 27. The second link section 276 runs parallel to the direction of movement of the slide plate 27. The link pin 283 is displaced laterally within the first link section 275 when the slide plate 27 moves, thereby pivoting the locking slide lever 28.If the guide pin 283 is located in the second guide area 276, it is not displaced laterally. It remains stationary when the slide plate 27 continues to move in the unlocking direction (parallel to the face plate 22 upwards), thus holding the bolt slide lever 28 in its unlocked position, in which the bolt ejector 5 and the latch ejector 4 have each reached their unlocked positions.

[0100] When moving the deadbolt lock 2 from the locked position according to Fig. 2 or Fig. 3 or Fig. 4 The spring drive 6 of the drive bolt lock 2 is loaded into an unlocked position. The spring drive 6 of the drive bolt lock 2 comprises two compression springs 61 and 62. The compression spring 61 acts on the slide plate 27. The compression spring 62 acts on the lower retraction slide 251. As can be seen by comparing the Figuren 2 and 3As can be seen, when the espagnolette lock is unlocked, the two springs 61 and 62 are compressed. In order to move the espagnolette lock 2 from the unlocked position according to Fig. 5 back to the locked position according to Fig. 4 to guide, the spring drive 6 is released so that the espagnolette lock 2 is returned to its locked position while discharging the energy stored in the springs 61 and 62.

[0101] In addition to the Fig. 5 The motorized unlocking position of the deadbolt lock 2 shown in Fig. 13 the unlocking of the espagnolette lock 2 is shown in a manual manner by turning the lock nut 23. By turning the lock nut 23 counterclockwise, the nut lever 231 is also turned counterclockwise, whereby, as in Fig. 14 Shown enlarged, the roller 233 of the nut lever 231 carries the lower retraction slide 251 upwards. This occurs when the roller 233 is in contact with the slide stop surface 252 and, when the nut lever 231 is rotated, this is actuated upwards together with the retraction slide 251. In this case, the reversing lever 26 is pivoted, as previously with the motorized unlocking, and carries the upper retraction slide 241 downwards, which leads to the immediate retraction of the driving bolt rods 24 and 25.

[0102] When manually unlocking using the nut lever 231, it should be noted that the rotational speed of the reversing lever 26 is, at least initially, higher than with the motorized unlocking. Figur 10 As can be seen from the dashed lines, the effective lever 91 between the point of application 254 and the pivot point 264 of the bell crank is greater than the effective lever 92 between the pin of the slide plate 274 and the pivot point 264 of the bell crank 26. This has the effect that when the lock nut rotates, i.e. during manual unlocking, the bell crank 26 disengages from the slide roller 274, in particular lifts off from it. This separates the unlocking of the espagnolette bars from the motor influence. This means that the manual unlocking cannot be influenced by the motor 3, so that it is guaranteed at all times that the espagnolette lock 2 can be unlocked manually via the lock nut 23.

[0103] Furthermore, the nut lever 231 has a driver 232 to drive the locking slide lever 28. As in Fig. 13 As shown, due to the stop between the driver 232 and the bolt slide lever 28, the latter is also rotated counterclockwise when the lock nut 23 is actuated in order to move the latch ejector 4 and the bolt ejector 5 into the unlocked position. As a result of the rotation of the bolt slide lever 28, the slide plate 27 is also actuated upwards parallel to the face plate. This is shown in Fig. 13 This is illustrated by the fact that the stop pins 271 and 272 are lifted from the stop surfaces 331 and 332 of the spindle drive 31, i.e., they are not operatively engaged. However, since the slide roller 274 follows the reversing lever 26, i.e., the reversing lever 26 is not engaged with the slide plate 27, this displacement of the slide plate 27 has no disruptive influence on the mechanical or manual unlocking of the deadbolt lock 2.

[0104] In Fig. 14 It is shown that the roller 233 of the nut lever 231 runs on a slide stop surface 252 of the lower feed slide 251.

[0105] When motor-driven unlocking of the deadbolt lock 2 as in Fig. 5 As shown, the nut lever 231 remains stationary. The lower feed slide 251, however, is moved upward by a motor. This causes the slide stop surface 252 to lift off the roller 233 of the nut lever 231.

[0106] Based on the Fig. 13 The locking of the drive bolt lock 2 is again made possible in the same way by the support of the spring drive 6. In Fig. 13 It can be seen that both springs 61 and 62 of the spring drive 6 are charged. With the support of these two springs 61, 62, the deadbolt lock 2 can be opened from the position shown in Fig. 13 shown unlocking position back to the locked position according to Fig. 4 be spent.

[0107] In the Fig. 15 For a better overview, the interaction between the bolt slide lever 28 and the latch ejector 4 is shown. According to the illustration in Fig. 15 The trap ejector 4 is connected to the trap deflection lever 41 by means of a pin guided in a guide.

[0108] The Fig. 16 shows the connection of the latch ejector 4 to the latch deflection lever 41. The latch deflection lever 41 is designed as a two-armed pivot lever, the other arm of which is also guided via a pin in a link of the first bolt slide arm 281. If for unlocking as in Fig. 15 indicated by an arrow, the bolt slide lever 28 is turned counterclockwise, the latch deflection lever 41 reverses the movement, which leads to the latch ejector 4 being in the Fig. 16 shown arrow direction out of the lock housing 21 of the espagnolette lock 2 in order to unlock a locking element, in particular a latch of an active wing lock.

[0109] It is advantageous that the espagnolette lock 2 has a lock housing 21 with several installation spaces 81, 82, 83, 84, 85 for accommodating optional functional components or modules or components. A latch ejector 4 can also be exchanged for a door opener 44 or vice versa. Use of the espagnolette lock 2 without the latch ejector 4 and door opener 44 is also possible. Furthermore, the espagnolette lock can optionally be upgraded with sensors 71, 72, 73, 74, 75, 76, 77, 78, 79 and a control device 7. In addition, the espagnolette lock can be used with just one espagnolette rod, for example an upper espagnolette rod 24 or a lower espagnolette rod 25. To enable secure locking, both espagnolette rods 24 and 25 can also be used. All of these functional components orModules or components can be combined or omitted as desired to optimally adapt the espagnolette lock to the specific application. One advantage is that the dimensions of the lock housing remain unchanged when upgrading or dismantling functional components, modules, or components. The lock housing 21 has uniform, standardized dimensions in all variants, which significantly simplifies installation and subsequent upgrading of the espagnolette lock 2. List of reference symbols
