Description

[0001] The invention relates to a method for operating a deadbolt lock according to the features of the preamble of claim 1, as well as a deadbolt lock according to the features of the preamble of claim 4.

[0002] In practice, motorized locks are typically used for the active leaf of double-leaf doors to allow independent opening of the active leaf. For example, during the day, for frequent use, it should be possible to unlock the active leaf and open only that leaf while the passive leaf or inactive leaf remains locked. This is commonly referred to as a daytime lock. However, using a motorized lock is relatively complex and expensive.

[0003] Document DE 10 2016 108 706 A1 discloses a motorized passive sash lock that can be moved into a central position by means of a motor. In this position, the latch ejector and the deadbolt ejector are in an unlocked position to unlock an active sash lock, but the deadbolt rods are still locked. For this purpose, the motor is actuated in a first direction to actuate only the deadbolt ejector and the latch ejector. If the deadbolt lock is to be fully unlocked, the actuation direction of the motor must be reversed to also unlock the deadbolt rods. The disadvantage of this solution is that immediate and secure unlocking of the deadbolt lock is not possible from every position, since for full unlocking the motor must first switch its actuation direction, and a certain amount of idle time must be overcome by the motor mechanism to unlock the deadbolt rods.

[0004] EP 2 264 268 B2 discloses a motorized espagnolette lock that implements sequential actuation of the bolt ejector, latch ejector, and espagnolette rods. This means that in a first drive range of the motor, only the latch ejector and the bolt ejector are actuated. Only after this first actuation range has been completed are the espagnolette rods driven for unlocking. This solution also has the disadvantage that, at least in the first actuation range, there is no effective connection for unlocking the espagnolette rods. Therefore, in the event of an emergency release, a certain amount of idle time must always be overcome.

[0005] EP 2 749 721 B1 shows a shoot-bolt lock that can be unlocked either by motor or manually. The movement sequence is two-stage, both for motor and manual unlocking. This means that in both cases, a center position must first be reached and passed over to unlock the shoot-bolt lock. Furthermore, the design of this shoot-bolt lock is very complex and features a multitude of interacting gear elements.

[0006] The invention is based on the object of providing a cost-effective solution for accessing the active leaf of a double-leaf door when the passive leaf is locked. In particular, this solution should achieve a high level of functional reliability. Furthermore, it should be suitable for use in escape and rescue routes. In particular, rapid and reliable unlocking should be possible at any time in an emergency.

[0007] This object is achieved according to the invention by a method for operating a deadbolt lock according to the features of claim 1 and by a deadbolt lock according to the features of claim 4.

[0008] According to the invention, a method for operating a shoot bolt lock is proposed in order to lock and unlock a passive leaf of a double-leaf door in the closed position by means of at least one shoot bolt rod, wherein a shoot bolt lock is provided, comprising a lock housing and at least one retractable slide connectable to a shoot bolt rod and comprising a bolt ejector and / or a latch ejector in order to unlock a bolt and / or a latch of an active leaf lock of the double-leaf door, wherein the at least one shoot bolt rod and the bolt ejector and / or latch ejector can be moved manually by means of a lock nut with a nut lever by pivoting the lock nut over a defined pivot range, or motorically by means of a motor by moving a motor output over a defined travel range from a locked position to an unlocked position.What is important here is that when unlocking by means of a lock nut, the at least one retracting slide is actuated together with the bolt ejector and / or latch ejector, so that the at least one retracting slide moves into the unlocked position together with the bolt ejector and / or latch ejector, and that the travel range of the motor output is divided into two travel ranges with an intermediate middle position, and when unlocking by motor in the first travel range the at least one retracting slide is actuated together with the bolt ejector and / or latch ejector, and in the second travel range essentially only the at least one retracting slide is actuated in order to move the at least one driving bolt rod into the unlocked position after the bolt ejector and / or latch ejector.

[0009] According to the invention, a shoot bolt lock is also proposed for locking and / or unlocking a passive leaf of a double-leaf door, in particular for operating a method according to one of the preceding embodiments, with a lock housing and with at least one retracting slide for moving at least one shoot bolt rod, and with a bolt ejector and / or a latch ejector for urging a bolt or a latch of an active leaf lock out of the lock housing for unlocking, wherein the shoot bolt lock can be unlocked manually by means of a lock nut with a nut lever rotatably mounted in the lock housing, and can be unlocked by a motor by means of a motor accommodated in the lock housing, which motor is connected to a control device.What is important here is that, starting from the locked position, the motor can be controlled by the control device into a central position in which the motor has moved the bolt ejector and / or the latch ejector into their unlocked position, and the at least one retracting slide or the at least one espagnolette rod is still in a locked position, and that when unlocking by means of the lock nut, the at least one retracting slide is moved synchronously with the bolt ejector and / or the latch ejector in such a way that the bolt ejector and / or the latch ejector reach(s) the unlocked position together with the at least one retracting slide.

[0010] One advantage is that the motor drive is operatively engaged at all times, starting from the locked position, to move both the bolt ejector and the latch ejector into the unlocked position, as well as the at least one retracting slide with the espagnolette bar. Already at the beginning of the travel range of the motor drive, both the at least one retracting slide with the at least one espagnolette bar, as well as the bolt ejector and latch ejector, are motor-actuated into the unlocked position. Only after the bolt ejector and latch ejector have reached the unlocked position are the espagnolette bars actuated over a certain distance, i.e., retracted into the lock housing, and thus completely unlocked.Since the motor output is in active connection during every phase of unlocking, safe unlocking can be achieved at any time without having to drive through an empty area or having to control the motor output in any other way.

[0011] Another advantage is that the espagnolette lock can be manually unlocked from any position as quickly as possible in an emergency. In particular, manual unlocking eliminates the need for a long journey via a center position; instead, the door can be quickly and completely unlocked with a single movement, allowing both door leaves to be opened quickly in an emergency. Nevertheless, the espagnolette lock has a motorized center position, eliminating the need for a door opener or a motorized active leaf lock, for example.

[0012] Preferably, the espagnolette lock can be formed with a espagnolette bar, for example an upper espagnolette bar, or with two espagnolette bars, an upper and a lower espagnolette bar.

[0013] 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 the door.

[0014] In particular, the unlocked position of the espagnolette lock is understood to mean a position in which the two espagnolette bars are completely retracted into the lock housing, such that the espagnolette bars no longer interact with a locking receptacle, so that the passive leaf can be opened.

[0015] In particular, the middle position of the espagnolette lock is understood to mean a position in which at least one espagnolette rod or both espagnolette rods are still extended far enough out of the housing that they are in operative engagement with a locking receptacle on the door frame and / or on the floor. The bolt ejector and / or the latch ejector have already reached their unlocked position, i.e. they have already pushed a lock bolt and / or a latch of an active lock out of the lock housing of the espagnolette lock. In this position, the active leaf can be opened when the inactive leaf is locked. This middle position can, for example, be implemented as a day position to enable easy access to the active leaf when the inactive leaf is locked.

[0016] In particular, it can be provided that the bolt ejector and / or the latch ejector move into their unlocked position upon reaching the center position, or are in their unlocked position in the center position. This ensures that in the center position the bolt ejector and / or the latch ejector have already assumed their final position with regard to unlocking, so that an active leaf lock is securely unlocked in the center position and an active leaf can be easily accessed without the active leaf lock first having to be laboriously unlocked. In particular, it is provided that the at least one retraction slide is still in a locked position in the center position. This enables the passive leaf to still be securely locked in the center position.

[0017] In particular, it can be provided that, starting from the locked position, during motor-driven unlocking, the at least one retracting slide is moved more slowly than the bolt ejector and / or the latch ejector, such that the at least one retracting slide reaches the unlocked position after the bolt ejector and / or the latch ejector, and that during unlocking via lock nut, the at least one retracting slide is moved synchronously with the bolt ejector and / or the latch ejector, such that the bolt ejector and / or the latch ejector reach or reach the unlocked position together with the at least one retracting slide. This advantageously ensures that there is an operative engagement between the motor drive and the bolt ejector and / or the latch ejector and the retracting slide or the driving bolt rods throughout the entire movement sequence of the motor-driven unlocking.In the case of manual unlocking via lock nut, it is ensured that the espagnolette bars are unlocked together with the bolt ejector and / or latch ejector, so that a quick emergency opening is possible in the case of manual unlocking without the need for any idle strokes or the need for complex coupling or decoupling of drive components.

[0018] In one embodiment, the espagnolette lock can have an upper retractable slide with an upper espagnolette bar and a lower retractable slide with a lower espagnolette bar, with the two retractable slides being directly connected to each other via a bell crank. Preferably, "direct" refers to a direct connection. This means that the two retractable slides are connected only via a single bell crank. Additional components for connecting the two retractable slides are not required.

[0019] 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.

[0020] In particular, a 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.

[0021] 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.

[0022] Preferably, in one embodiment, it can be provided that the lock housing has a faceplate and a slide plate that can be moved by the motor parallel to the faceplate, and the control device comprises at least three sensors to detect the locked position, the middle position and the unlocked position.

[0023] 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.

[0024] Preferably, it can be provided that the motor is designed as a linear motor or has a spindle drive in order to move the slide plate in an unlocking direction, and the sensors interact with the linear motor and / or the spindle drive and / or the slide plate, in particular are arranged on the linear motor or the spindle drive or the slide plate in order to detect the locked position and / or the middle position and / or the unlocked position.

[0025] InIn one embodiment, it can be provided that the sensors comprise a proximity switch and / or a light barrier and / or a button, or that the sensors are designed as a proximity switch and / or a light barrier and / or a button. In particular, the sensors can interact with recesses in the slide plate. For example, the slide plate can have slots that are detected by the sensors. Various positions of the shoot bolt lock can be detected via the sensors, for example locked and / or unlocked and / or central position and / or intermediate positions. The proper functioning of the shoot bolt lock can also be monitored by means of the sensors. A defect can also be detected by means of the sensors and reported as an error.In particular, the sensor device is designed to evaluate the sensors and generate corresponding status messages or error messages and send them to a higher-level control center.

[0026] In one embodiment, the lock housing can accommodate an upper retractable slide, connectable to an upper deadbolt bar, and a lower retractable slide, connectable to a lower deadbolt bar. The two retractable slides are connected to each other via a bell crank. The deadbolt bars can be screwed to the retractable slide, locked, or secured in a receptacle by clamps or clamping screws.

[0027] In one 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.

[0028] In particular, it can be provided that the point of action of the lower feed slide acts on the same arm of the two-armed reversing lever as the slide pin or the slide roller of the slide plate, or that the point of action of the upper feed slide acts on the other arm of the two-armed reversing lever as the slide pin or the slide roller of the slide plate.

[0029] In one embodiment, it can be provided that, at least in a locking position, the effective lever between the pivot point of the reversing lever and the point of action of the upper or lower retraction slide is greater than the effective lever between the pivot point of the reversing lever and the slide pin or the slide roller of the slide plate. This allows the distance traveled by the reversing lever to be greater when the upper or lower retraction slide is acted upon than when the reversing lever is acted upon by the slide pin of the slide plate.

[0030] In order to enable a compact construction, it can be provided in one embodiment that the nut lever is arranged in the lock housing between the lower retraction slide and the deflection lever in a plane parallel to the lock base and / or the lock cover of the lock housing.

[0031] Preferably, 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 cooperates with the slide plate via a link pin guided in a link guide of the slide plate, and the second arm of which cooperates 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.

[0032] To ensure reliable operation of the latch ejector, the second arm of the bolt slide lever can be configured to actuate the latch ejector via a latch reversing lever, moving it between an unlocked position and a locked position. This allows the bolt ejector and latch ejector to be actuated via the same component, increasing functional reliability and enabling a compact design.

[0033] 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.

[0034] 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.

[0035] In particular, it can be provided that the guide rail of the slide plate has two regions, wherein the first guide rail region runs obliquely to the unlocking direction in order to pivot the locking slide lever between its locked position and the unlocked position, and the second guide rail region runs parallel to the unlocking direction in order to hold the locking slide lever in the unlocked position.

[0036] Advantageously, it can be provided that the link guide is designed in such a way that the locking slide lever has already reached its unlocked position starting from the locked position in the middle position of the motor.

[0037] It can be provided that in the middle position the link pin of the locking slide is located in the transition area between the first link area and the second link area of ​​the link guide of the slide plate.

[0038] In order to keep the actuating forces during manual unlocking low, it can be provided that the nut lever has a pin or a roller by means of which it interacts directly with the lower retraction slide or the upper retraction slide, in that the lower retraction slide or the upper retraction slide has a slide stop surface for the pin or the roller, such that the nut lever acts on, in particular pushes, the lower retraction slide or the upper retraction slide in the unlocking direction via the pin or the roller during manual unlocking.

[0039] In order to achieve a compact design of the espagnolette lock, it can be provided that the axis of rotation of the bell crank runs parallel to the axis of rotation of the lock nut and the control curve of the bell crank is arranged on a side surface of the bell crank facing away from the lock nut.

[0040] In order to reduce the influence between motorized and manual operation of the espagnolette lock, it can also be provided that the slide stop surface of the lower retracting slide or the upper retracting slide is disengaged from the pin or the roller of the nut lever during motorized unlocking, in particular that the slide stop surface lifts off the pin or the roller of the nut lever.

[0041] In particular, it can be provided that the slide stop surface of the lower retraction slide or the upper retraction slide is part of a stop curve, on which the pin or roller of the follower lever runs when the upper or lower retraction slide is disengaged from the pin or roller of the follower lever during motorized unlocking. The design of the slide stop surface as a stop curve enables it to run on the stop curve and thus be guided, even when the pin or roller of the follower lever is lifted from the stop surface.

[0042] In order to reduce the actuating forces during motorized unlocking, it can be provided that the slide plate has a slide pin or a slide roller, wherein the slide pin or the slide roller acts on the reversing lever in that the slide pin or the slide roller runs on a control curve of the reversing lever in order to pivot the reversing lever.

[0043] It can be provided that when unlocking by means of a lock nut, the reversing lever runs ahead of the slide pin or the slide roller and thus comes out of operative engagement with the slide plate, in particular by the control cam of the reversing lever lifting off the slide pin or the slide roller.

[0044] In one embodiment, it can be provided that the control curve of the deflection lever is designed in such a way that, during a motorized unlocking starting from the locking position, the rotation rate of the deflection lever is smaller, at least at the beginning of the motorized unlocking, than towards the end of the motorized unlocking.

[0045] In order to prevent the motorized unlocking and the manual unlocking from being influenced, it can be provided in one embodiment that the slide stop surface of the lower retraction slide or the upper retraction slide comes out of active engagement with the pin or the roller of the nut lever during motorized unlocking, in particular that the slide stop surface lifts off the pin or the roller of the nut lever.

[0046] Furthermore, mutual influence of motor and manual unlocking can be reduced by preferably providing that the motor has a stop surface in its motor output, which is in contact with a stop pin of the slide plate in order to motor-actuated the slide plate into an unlocking position.

[0047] In particular, when unlocking via the lock nut, the slide plate can become disengaged from the stop surface of the motor output, in particular the stop pin of the slide plate lifts off the stop surface of the motor output.

[0048] In particular, it can be provided that the motor gear pushes the slide plate in the unlocking direction by means of a one-sided contact, wherein the one-sided contact is open in the unlocking direction. One-sided contact can be understood, for example, that the motor gear has a pin in the output that acts on a contact surface of the slide plate, or that the slide plate has a pin that is pushed by a contact surface of the motor gear. It is important that the contact is one-sided so that on the other side there is no obstruction to the movement of the slide plate, so that the slide plate can move away from the contact in the unlocking direction. This means that the slide plate can be moved further in any position of the motor or motor gear, for example by manual mechanical unlocking, without the motor or motor gear causing a jamming situation.

[0049] For particularly good guidance of the slide plate, one embodiment can provide that the motor gear in the output has two stop surfaces, each of which is in contact with a stop pin of the slide plate in order to motor-drive the slide plate into an unlocking position.

[0050] In particular, it can be provided that the two stop pins of the slide plate are arranged on different sides of the motor output, in particular on different sides of the spindle drive in such a way that a spindle of the spindle drive runs between the two stop pins. In this way, the force of the spindle drive is evenly distributed between the two stop pins to the left and right of the spindle in such a way that no one-sided torque acts on the slide plate and it is moved linearly, i.e. parallel to the face plate in the lock housing, without the motor being able to exert lateral pressure on the slide plate. This has the advantage that the frictional forces when the slide plate moves are also minimized, and the risk of jamming is likewise minimized.

[0051] In an advantageous embodiment, it can be provided that a spring drive is accommodated in the lock housing, and the two driving bolt rods are moved into an unlocking position by motor or manually actuated by the lock nut while charging the spring drive and are supported by the spring drive when extending into the locking position, preferably are moved into the locking position by the spring drive.

[0052] Preferably, the spring drive can have 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 the springs are designed as helical springs and / or compression springs.

[0053] The inventive concept also includes a locking device for a double-leaf door comprising a fixed leaf and a moving leaf, wherein the fixed leaf has a shoot bolt lock according to one of the embodiments described herein, and the moving leaf has an anti-panic lock with a bolt and / or a latch, and wherein the shoot bolt lock has a bolt ejector and / or a latch ejector in order to unlock the bolt and / or the latch of the anti-panic lock in a motorized or manually driven manner.

[0054] In particular, the espagnolette lock can be designed according to DIN EN 179 to enable use in fire and smoke protection doors. Alternatively and / or additionally, the espagnolette lock according to the invention can also be designed according to DIN EN 1125 to enable use in panic doors.

[0055] 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. 2: a schematic representation of the drive bolt lock in a locked position; Fig. 3: the drive bolt lock according to Figure 2 in a motor-unlocked position; Fig. 4: the deadbolt lock according to Figure 2 in the middle position; Fig. 5: the cut-out slide plate with the bell crank of the deadbolt lock; Fig. 6: the connection of the bell crank to the lower retraction slide; Fig. 7: the connection of the bell crank to the upper retraction slide; Fig. 8: the deadbolt lock according to Figure 2in a manually unlocked position; Fig. 9: the connection of the nut lever to the lower retraction slide; Fig. 10: a schematic representation of the interaction between the bolt slide and the latch deflection lever; Fig. 11: the latch ejector with the latch deflection lever.

[0056] 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.

[0057] The Fig. 1shows 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.

[0058] Likewise, the active leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via door hinges 133, 134.

[0059] 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. 1the 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.

[0060] 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. 2The 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.

[0061] Furthermore, the espagnolette lock 2 comprises a bolt ejector 5 and a latch ejector 4. In the Fig. 2In the locked position shown, the espagnolette bars 24, 25 are extended upwards and downwards from the lock housing 21 to their maximum extent. The latch ejector, like the bolt ejector 5, is 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 of an active leaf lock.

[0062] Furthermore, the espagnolette lock 2 comprises a motor drive comprising an electric drive motor 3 with a motor output 31, which is designed as a spindle drive. The motor output 31 comprises a spindle 32 and a spindle nut 33. The spindle nut has two stop surfaces 331 and 332, each of which interacts with a pin of a slide plate 27. The slide plate 27 is mounted in the lock housing 21 parallel to the forend 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.

[0063] 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.

[0064] Furthermore, the espagnolette lock 2 has a lock nut 23, via which the espagnolette lock 2 can be unlocked manually or mechanically. The lock nut 23 is connected in a rotationally fixed manner to a nut lever 231. The nut lever 231 has a driver 232 on its upper side for actuating or driving a bolt slide lever 28.

[0065] 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. The lower bolt slide arm 282 interacts with the bolt ejector 5. When the bolt slide lever 28 is rotated counterclockwise, both the bolt ejector 5 and the latch ejector 4 are actuated into the unlocked position, i.e. moved towards the face plate 22. This allows locking elements of an active sash lock (not shown) that engage in the lock housing 21 of the shoot bolt lock 2 to be displaced from the latter into an unlocked position.

[0066] The two feed slides 241, 251 are connected to each other via a reversing lever 26. As can be seen from Figure 6 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 ( Figure 7 ).

[0067] As well as from Figure 9 As can be seen, the nut lever 231 has a roller 233 at its end, which interacts with the lower retraction slide 251. When the lock nut 23 is rotated, the nut lever 231 is moved counterclockwise, whereby the roller 233 lifts the lower retraction slide 251 in order to retract the lower espagnolette rod 25.

[0068] The lock housing 21 further comprises a control device 7. The control device 7 is connected to the motor 3 in order to control it. The control device 7, and thus the motor 3, are electrically connected via a connecting cable 18 and are supplied with electrical power and control signals via this cable 18.

[0069] 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 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. The sensors 71, 72, 73 are each designed as a light barrier and are passed through by a flag on the motor nut. Alternatively, the sensors 71, 72, 73 can also be designed as buttons or Hall sensors.

[0070] 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.

[0071] The espagnolette lock further includes a latch contact 74 for detecting the position of a latch of an active leaf lock. When the active leaf is closed and the espagnolette lock 2 is locked, the latch of the active leaf lock engages the latch receiving space of the lock housing 21, thereby actuating the latch contact 74. The control device 7 is connected to the latch contact 74 and evaluates its signal to detect the latch of the active leaf lock. The signal can also be sent via the control device 7 to a higher-level control center, for example, an access control device, via cable 18.

[0072] The espagnolette lock 2 further includes a latch contact 75 for detecting the position of a latch of an active leaf lock. When the active leaf is closed and the espagnolette lock 2 and the active leaf lock are locked, the latch of the active leaf lock engages the latch receiving space of the lock housing 21, thereby actuating the latch contact 75. The control device 7 is connected to the latch contact 75 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 or an alarm system.

[0073] In the Fig. 3 the deadbolt lock 2 is in accordance with Fig. 2 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. 3 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. 5 are shown, are in contact and thus take the slide plate 27 with them as they move upwards along the spindle. The slide plate leaves the switching range of the locking sensor 71, moves into the unlocked position, and there actuates the unlocking sensor 73.

[0074] 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 Figure 3, 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 Figure 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. Figure 3 Move to the unlocking position shown.

[0075] The Figure 4 shows the deadbolt lock according to the Figure 2 in the middle position. Starting from the Figure 2In 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 slot 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 latch ejector 4 is at the level of the face plate 22 or protrudes slightly above it. A locking element of an active leaf lock received in the lock housing is thereby forced out of the lock housing. A bolt or latch of an active leaf lock is thus disengaged from the lock housing 21.

[0076] At the same time, the slide plate 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.

[0077] 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 Figure 2 The second end position is the motorized unlocked position according to Figure 3 . The middle position according to Figure 4 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.

[0078] In Fig. 5 The principle of unlocking the drive bolt rods when the slide plate 27 is motorized is shown. As shown in Fig. 5As can be seen, the slide plate 27 has a slide roller 274, which interacts with a control cam 263 of the bell crank 26. The bell crank 26 is rotatably mounted about the pivot point 264. The control cam 263 is arranged on the first arm 261 of the bell crank 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 bell crank 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 Figure 6The connection of the upper feed slide 241 to the reversing lever 26 is shown in detail in the Figure 7 shown. During unlocking, the bell crank 26 is pivoted along the arrow shown around the pivot point 264.

[0079] The upper section of the slide plate shows the guide rail 273, in which the guide rail pin 283 of the locking slide lever 28 is guided. The guide rail has two differently oriented guide rail sections 275, 276. The first guide rail section 275 runs diagonally to the unlocking direction in order to pivot the locking slide lever between its locked position and the unlocked position. When the slide plate 27 moves, the guide rail pin 283 runs along the guide rail 273. The first guide rail section 275 runs diagonally to the direction of movement of the slide plate 27. The second guide rail section 276 runs parallel to the direction of movement of the slide plate 27. When the slide plate 27 moves, the guide rail pin 283 is displaced laterally within the first guide rail section 275, 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.

[0080] When moving the deadbolt lock 2 from the locked position according to Figure 2 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 Figure 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 Figure 3 back to the locked position according to Figure 2 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.

[0081] In addition to the Figure 3 The motorized unlocking position of the deadbolt lock 2 shown in Figure 8 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 Figure 9Shown 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. As previously done with the motorized unlocking, the reversing lever 26 is pivoted and carries the upper retraction slide 241 downwards, which leads to the immediate retraction of the driving bolt rods 24 and 25.

[0082] 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. Figure 5As 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.

[0083] Furthermore, the nut lever 231 has a driver 232 to drive the locking slide lever 28. As in Figure 8As 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 Figure 8 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, i.e., the reversing lever is not engaged with the slide plate, this displacement of the slide plate 27 has no disruptive influence on the mechanical or manual unlocking of the deadbolt lock.

[0084] In Figure 9It is shown that the roller 233 of the nut lever 231 runs on a slide stop surface 252 of the lower feed slide 251.

[0085] When motor-driven unlocking of the deadbolt lock 2 as in Fig. 3 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.

[0086] Based on the Figure 8 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 Figure 8 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 Figure 8shown unlocking position back to the locked position according to Figure 2 be spent.

[0087] In the Figure 10 For a better overview, the interaction between the bolt slide lever 28 and the latch ejector 4 is shown. According to the illustration in Figure 10 The trap ejector 4 is connected to the trap deflection lever 41 by means of a pin guided in a guide. Figure 11 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 Figure 10 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 Figure 11shown 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.

[0088] It is advantageous that in the espagnolette lock 2 the motorised unlocking by means of motor 3 and slide plate 27 is separated from the mechanical unlocking by means of lock nut 23 and nut lever 231. The chain of effects for the motorised unlocking runs via the motor 3 or the motor gear 31 and the slide plate 27 to the relay lever 26. The chain of effects for the manual unlocking runs via the lock nut 23, the nut lever 231 to the lower retraction slide 251. By separating the operative engagement between the slide plate 27 and the relay lever 26 both for manual unlocking via lock nut 23 and by disengaging the operative engagement between the motor output and the slide plate or nut lever 231 and the lower retraction slide 251 for motorised unlocking, it is ensured that no disruptive interaction can arise between manual actuation and motorised actuation.This ensures that the espagnolette lock 2 can be unlocked at any time. Starting from any position, the espagnolette lock 2 can be unlocked both manually and by motor without causing interference with either drive mechanism. List of reference symbols
