Description

[0001] The invention relates to a lock, in particular a door lock, with at least a lock housing (e.g., attachable or attached to a lock face), a locking cylinder (for unlocking and / or opening the lock or door), a locking element (or several locking elements), e.g., a bolt and / or a latch, an actuating device (e.g., a lock nut) for actuating (e.g., for retracting) the locking element, an activation device with a drive arranged in or on the lock housing, with which the actuating device (e.g., the lock nut) can be activated (and, if necessary, deactivated), wherein the activation device has a controller (in particular for controlling the drive) and a receiver for receiving an activation signal received from a transmitting device, wherein the activation device is equipped with or connected to a learning device with which the activation device or its controller can be put into a learning mode in order to teach a transmitting device to the activation device or its controller, wherein the learning device has a learning button that can be actuated from the outside through the lock housing.

[0002] The lock can be a mortise lock or a center lock of a multiple-point locking system. The lock has at least one locking element, which can be, for example, a bolt, a latch, or a so-called deadbolt. The actuating device for actuating this locking element can be, for example, a lock nut that is rotatably mounted in the lock housing and into which at least one actuating pin for an actuating handle, e.g. a handle or a panic bar, can be inserted. It is therefore preferably a lock in which the locking element or locking elements can be retracted by actuating the actuating device, e.g. the lock nut. The actuating device, e.g. the lock nut, can be activated using the activation device or using the drive of the activation device and, for example,can be coupled, so that the lock nut or - in the case of a split lock nut - one of the nut halves can be optionally coupled to or decoupled from the lock mechanism. The drive can be an electric motor drive, for example, so that an electrically coupled lock is created. Such a lock can be activated and deactivated via remote control, e.g. a transmitter, and thus control access authorisation. If, for example, the lock nut or at least the outer nut of a split lock nut is deactivated via the activation device and thus decoupled from the lock mechanism, access from the outside is blocked. Access can be granted by activating and consequently coupling the lock nut or the outer nut with the lock mechanism. For this purpose, the activation device assigns aa receiver integrated into the lock housing or attached to the lock housing so that an activation signal (or alternatively a deactivation signal) can be transmitted to the activation device using a separate transmitting device, e.g. a hand-held transmitter.

[0003] In practice, it is necessary to "teach" a transmitting device, e.g., a radio handheld transmitter, to the lock and consequently to the lock's activation device, so that the lock can only be activated with a trained and therefore authorized transmitting device. To teach a (new) transmitting device, the activation device or its (electronic) control is placed in a so-called "teaching mode." For this purpose, the lock has a teach-in button that can be operated from the outside through the lock housing. In practice, the teach-in button is arranged in the lock housing in such a way that it can be operated through the lock face, e.g., through an opening in the lock face. Since the lock face is only accessible when the door is open, this initially prevents a transmitting device from being taught when the door is closed.In order to prevent an unauthorized person from programming a transmitter when the door is open, additional protective measures are provided in practice.

[0004] For example, a mortise lock is known in practice where the programming button is covered by a cover and therefore inaccessible to unauthorized persons. To release this cover, a lock or latch on the cover must be released using a key inserted into the locking cylinder. This ensures that the programming button can only be accessed with a key and therefore only by authorized persons in possession of the key. After removing the cover, the programming button can be briefly pressed and then a designated button or key on the radio remote control can be pressed to program this handheld transmitter to the door lock.

[0005] The solution, as we know it from practice, has proven itself in principle. However, it can be improved.

[0006] Furthermore, EP 3 133 558 B1 describes a locking device, in particular a mortise lock, with a profile cylinder, an electronic control device, and a radio module coupled to the control device. Furthermore, a switching element is provided which is coupled to the control device, wherein the switching element can be actuated by actuating the profile cylinder with a suitable key. The locking device is switched to a pairing mode when the locking device is supplied with a supply voltage while the switching element is actuated, i.e., when it is brought from a de-energized to a voltage-energized state. For this purpose, a de-energized state is first established by removing an energy storage device, e.g., a battery.The switching element, which interacts with the control device, is then actuated by the profile cylinder while the locking device remains de-energized. Afterward, the locking device is subjected to voltage while the switching element is actuated. To do this, the battery is reinserted while the switching element remains closed with the key.

[0007] Based on the prior art, the object of the invention is to provide a lock of the type described above which enables a simple programming of a transmitting device with a simplified construction and minimal risk of manipulation.

[0008] To achieve this object, the invention teaches, in a generic lock of the type described at the outset, that the learning device has, in addition to the learning button, a locking cylinder switch which can be actuated with the locking cylinder to select the learning mode (directly or indirectly), wherein the activation device or its control is set up in such a way that the activation device is only put into the learning mode when both the learning button and the locking cylinder switch are actuated.

[0009] The locking cylinder switch can be a mechanical button or alternatively a contactless sensor, e.g. an optical, magnetic or inductive sensor, which is actuated or triggered by actuating the locking cylinder, also known as the profile cylinder. The locking cylinder switch can be actuated directly via the locking cylinder, e.g. via the locking bit. Preferably, however, the locking cylinder switch is actuated indirectly, in that the locking cylinder works in the usual way for actuating the lock mechanism via a profile cylinder driver, also known as the locking bit, on a slider that is coupled to the lock mechanism or is part of the lock mechanism. The locking cylinder switch is arranged in the effective range of this slider and can therefore be actuated by the slider.According to the invention, the control of the activation device is designed such that a (new) transmitting device can only be taught in if both the teach-in button (e.g. through the lock face) and the lock cylinder switch (e.g. simultaneously) are actuated.

[0010] The invention is based on the realization that manipulation, namely the unauthorized programming of a transmitting device, can be reliably prevented if the locking cylinder is integrated into the programming process and, consequently, programming is only possible with the aid of a key and thus only by persons who have a key for the respective lock. According to the invention, however, the locking cylinder is not used to remove a cover for the programming button, so that, according to the invention, an additional cover for the programming button can be dispensed with. This is because, according to the invention, an "electronic release" of the programming button takes place, triggered by actuation of the locking cylinder, which actuates a locking cylinder switch. The electronic control of the activation device therefore queries both the position or functional setting of the programming button and the position orThe activation device detects the functional position of the locking cylinder switch and only puts the activation device into teach-in mode when both the teach-in button and the locking cylinder switch are pressed, thus each generating an actuation signal. This is achieved very simply by electronically designing or programming the electronic control of the activation device without complex mechanical components and, in particular, without a mechanical cover for the teach-in button and without a mechanical coupling of the locking cylinder to the cover or a mechanism for releasing the cover. In addition to the teach-in button that is already present, only a suitable switch or sensor is required to query the position of the locking cylinder or a component coupled to the locking cylinder, e.g. a slider.What's particularly interesting in this context is that many locks are already equipped with a so-called "profile cylinder contact," and thus a profile cylinder contact or locking cylinder contact, to query the functional position of the locking cylinder or the mechanical component coupled to the locking cylinder. According to the invention, such an already existing locking cylinder switch or locking cylinder contact can be used.

[0011] According to the invention, however, the control is modified and consequently programmed in such a way that the learning mode is only permitted if the query of the locking cylinder position yields a corresponding result.

[0012] Preferably, the activation device or its (electronic) control is set up, e.g. programmed, in such a way that the activation device is only put into teach-in mode if the locking cylinder switch is actuated while the teach-in button is actuated or held. In order to teach in a radio hand-held transmitter or another transmitting device, the locking cylinder or the key can first be turned in a predetermined direction, e.g. in the opening direction, and held in this position so that the locking cylinder switch is actuated. While holding the position and consequently while the locking cylinder switch is actuated, the teach-in button is actuated and in this way the teach-in mode is started. The key can now be released and the new transmitting device can then be actuated in order to teach it in. Alternatively or additionally, the activation device or its (electronic) control can be set up, e.g.B. programmed in such a way that the activation device only goes into learn mode if the learn button is pressed while the locking cylinder switch is pressed or held. For example, to teach a radio hand-held transmitter or another transmitting device, the learn button can first be pressed and held. While holding it and consequently while the learn button is pressed, the locking cylinder or key is then turned in a predetermined direction, e.g. in the opening direction, so that the locking cylinder switch is actuated and in this way the learn mode is started. The learn button can now be released and the new transmitting device can then be actuated to teach it in. The control system can also be set up in such a way that the order in which the SZ switch and the learn button are actuated is irrelevant, as long as they are pressed simultaneously at times.

[0013] Alternatively, it is also possible to set up or program the control system so that one of the buttons or switches is first pressed and released, followed by the other switch being pressed and released within a time window. According to the invention, starting the teach-in mode always requires both the teach-in button and the lock cylinder switch to be pressed via the lock cylinder, either simultaneously or with an overlapping time, or alternatively, one after the other or with a time delay.

[0014] The lock cylinder switch can be a mechanical button that is actuated via the lock cylinder or via a lever or slider coupled to the lock cylinder. Alternatively, it can also be a contactless switch or sensor, e.g., an optical sensor, a magnetic sensor, or an inductive sensor. It must always be ensured that a signal is generated that is dependent on the position of the lock cylinder and that is evaluated by the electronic control system in order to carry out the described logical query. According to the invention, a logical query or a logical combination of the signals generated or provided by the teach-in button on the one hand and the lock cylinder switch on the other hand takes place in the electronic control system.

[0015] Using a trained transmitter, the activation device can be controlled and thus the actuating device, e.g., the lock nut or a nut half, can be activated and thus coupled to or uncoupled from the lock mechanism. In a preferred embodiment, the actuating device is therefore designed as a lock nut into which at least one actuating pin for an actuating handle, e.g., for a lever handle or a panic bar, can be inserted. Preferably, the lock nut can be actuated from both the inside and outside of the door, and at least one actuating pin for each actuating handle, e.g., an outside handle and an inside handle or a panic bar, can be inserted into the lock nut on both sides.The activation device is preferably designed as a coupling device which has a coupling element which can be adjusted with the drive and thus activated for coupling the lock nut or at least one lock nut half (with the lock mechanism).

[0016] In a first embodiment, the lock nut is designed as a split lock nut with an outer nut assigned to the outside of the door and an inner nut assigned to the inside of the door. The inner nut, for example, is permanently coupled to the lock mechanism as a panic nut for retracting the locking element, and the outer nut can be coupled to and decoupled from the lock mechanism via the coupling element for retracting the locking element. Such an embodiment is particularly advantageous when the lock is designed as a panic lock, so that the door can always be opened from the inside, while access authorization can be specifically controlled from the outside via the activation device, for example by activating and optionally deactivating the outside handle using the transmitting device.

[0017] In a second embodiment, the lock nut is designed as a one-piece lock nut, which can be coupled to the lock mechanism via the coupling element to retract the locking element and can be decoupled from the lock mechanism. Using the activation device, the lock nut can then be activated and deactivated as a whole, so that when deactivated, the lock cannot be opened from either the outside or the inside of the door.

[0018] The coupling element can be a clutch lever that can be moved from the deactivated uncoupling position to an activated clutch position and vice versa via the drive. The clutch lever can be designed, for example, as a pivoting clutch lever. The drive can be, for example, an electric motor or electromagnetic drive, with which the clutch element, e.g., the clutch lever, can be moved into the respective functional positions.

[0019] The receiver of the activation device is preferably designed as a radio receiver for receiving radio signals. Accordingly, the transmitting device is preferably designed as a radio transmitting device with a radio transmitter.

[0020] The invention also relates to a locking system with a lock of the type described and with a lock face that can be fastened to a door leaf, wherein the lock or its lock housing is fastened to the back of the lock face. In principle, the lock according to the invention can be a (simple) mortise lock. Preferably, however, a locking system in the embodiment as a drive rod lock with multiple locking is claimed, wherein the described lock with the activation device according to the invention is fastened to the lock face as a central lock. In addition, at least one additional locking device is provided, which is coupled to the central lock via at least one drive rod. The additional locking device has an additional housing and at least one additional bolt that can be adjusted in the additional housing.

[0021] In a preferred embodiment, this is an automatically locking espagnolette lock which automatically locks when the door leaf moves into the closed position. For this purpose, a release mechanism is provided which automatically moves one or more locking elements into the extended locking position when the door leaf moves into the closed position. This release mechanism can be arranged, for example, in the additional locking mechanism, so that the additional bolt is automatically moved into the extended locking position when the door leaf moves into the closed position. In a particularly preferred embodiment, the center lock is also coupled to this release mechanism, so that the center latch bolt is coupled to the release mechanism of the additional locking mechanism in such a way that when released, both the additional bolt and the center bolt are automatically extended into the locking position.

[0022] The lock, which can be designed as a mortise lock or as a center lock of a multi-point locking system, has at least one locking element in addition to the locking cylinder. This can be a conventional deadbolt and / or a spring-loaded latch. In one possible embodiment, the locking element is designed as a deadbolt and thus as a center latch, which has a beveled actuating edge and is biased toward an extended locking position by a latch spring.

[0023] At least one locking element is also provided in the additional locking mechanism. This can be, for example, a latch bolt. Alternatively or additionally, a swivel hook bolt and / or a bolt bolt can be provided. The design of the additional locking mechanism can be based on the embodiments described in DE 10 2008 011 551 A1 or EP 3 372 757 B1, for example.

[0024] The invention also relates to a method for operating a lock of the type described. The components and method steps described in connection with the lock, in particular the learning process, therefore also relate to the claimed method.

[0025] The invention will be explained in more detail below with reference to drawings which merely represent exemplary embodiments. Fig. 1 a drive rod lock with a lock according to the invention as a center lock in a simplified perspective view, Fig. 2 the center lock of the article according to Fig. 1 in a first view, Fig. 3 the center lock after Fig. 2 in a second view, Fig. 4 an additional locking of the espagnolette lock according to Fig. 1 in a first view, Fig. 5 the additional lock according to Fig. 4 in a second view, Fig. 6 a section of the center lock in a first functional position and Fig. 7 the object according to Fig. 6 in a second functional position.

[0026] The figures show an example of a locking system in the form of a drive rod lock 1 with multiple locking. Fig. 1shows a drive rod lock 1 that can be mounted on a door leaf, which on the one hand has a central center lock 2 and on the other hand two additional locking mechanisms 3, 4, namely an upper additional locking mechanism 3 and a lower additional locking mechanism 4, which are coupled to the center lock 2 via drive rods 5, 6, namely an upper drive rod 5 and a lower drive rod 6. The center lock 2 and the additional locking mechanisms 3, 4 are fastened to the rear of a lock face 7, which in turn is mounted on the door leaf. At least one locking strip is fastened to a door frame (not shown), which has perforations or openings into which the locking elements of the drive rod lock 1 engage during locking.

[0027] The invention relates in particular to the design and function of the lock 2, which in the exemplary embodiment is the center lock 2 of the espagnolette lock 1. The lock or center lock 2 has a housing 8 fastened to the lock face 7 (i.e. center housing 8) and at least one locking element 9 which is adjustable in the housing 8 and is referred to as the center bolt 9. The two additional locking devices 3, 4 each have an additional housing 10 fastened to the lock face 7 and one or more additional bolts 11, 12 each. The figures show only an example of an embodiment in which each additional locking device has two locking elements, namely a latch bolt 11 on the one hand and a pivoting hook bolt 12 on the other.

[0028] The figures show, merely by way of example, one embodiment of a drive rod lock, which is referred to as an automatic lock. For this purpose, a release mechanism 13 is implemented in each of the additional locking devices 3, 4, with which the additional bolts 11, 12 of the additional locking devices 3, 4 are automatically transferred into the extended locking position when the door leaf moves into the closed position. In this embodiment, the release is implemented as a magnetic release. For this purpose, release magnets 14 are arranged in the area of ​​the door frame, e.g., in the respective locking strip. As soon as the door leaf moves into the closed position, the additional locking devices 3, 4 enter the effective range of the release magnets 14, thereby triggering the automatic locking mechanism. The lock 1 is locked automatically, without the need for manual or electric motor activation by a user.The lock and door can be unlocked and opened by operating a handle from the outside or inside of the door. For this purpose, in the exemplary embodiment, a lock follower 15 is provided as an actuating device in the lock and consequently in the center lock 2. This can be a lock follower that can be operated from both the inside and outside of the door, into which an actuating pin (not shown) for a handle, e.g., for an inside handle and an outside handle, or alternatively, a panic bar on the inside of the door, is inserted.

[0029] This can be a connecting rod lock with a panic function, which is provided with a multi-part or split lock nut 15, which on the one hand has an outer nut 15a assigned to the outside of the door and on the other hand has an inner nut 15b assigned to the inside of the door. The inner nut 15b is, for example, permanently coupled to the lock mechanism as a panic nut for retracting the bolts 9, 11, 12. The outer nut 15a is not permanently coupled to the lock mechanism. According to the invention, the lock, specifically the center lock 2 in the exemplary embodiment, is provided with an activation device which has a drive 24 arranged in or on the lock housing, with which the actuating device, namely the locking nut 15 or at least the outer nut 15a, can be activated. This will be discussed in more detail below. By actuating the inner nut 15b, the connecting rod lock is preferably always completely unlocked, i.e.all locking elements 9, 11, 12 are fully retracted to allow the door to be opened.

[0030] The structure and functioning of the additional locking devices 3, 4 are generally known. These can, for example, be additional locking devices according to EP 3 372 757 B1. The additional locking device 3, 4 has at least one locking element, which is particularly preferably a latch bolt 11. In addition, the aforementioned swivel hook bolt 12 is provided in the illustrated embodiment. Provided in the additional housing 10 is a lock chain 17 which is displaceable in the longitudinal direction L of the lock and is referred to as the additional lock chain 17 and which is connected to the respective drive rod 5, 6 and with which the additional bolt or bolts can be retracted from the extended locking position into the retracted opening position (not shown) when the drive rod 5, 6 is displaced in the unlocking direction.The additional lock chain 17 is held in the unlocked position in front of a locking element 18, and the locking element 18 can be actuated for automatic locking by a release magnet 14 arranged in or on the door frame or the striker strip in such a way that the locking element 18 releases the additional lock chain 17, so that the additional bolt 11, 12 is automatically moved into the extended locking position. The latch bolt 11 can also be retracted by means of the lock chain 17 from the extended locking position or the (not shown) partially extended unlocked position into a (not shown) retracted opening position. The (not shown) partially extended unlocked position, which can also be referred to as the basic position, in which the spring-loaded latch bolt 11 projects by a predetermined amount from the lock housing 10 and over the face plate 7.As the door closes, the latch bolt 11 is pushed back into the lock housing 10 against the force of the spring. At the same time, the magnetic release automatically releases the latch bolt 11, moving it into the fully extended locking position shown in . Fig. 1 is shown. Additionally, the swivel hook latch 12 is extended. This mechanism is generally known.

[0031] The center latch bolt 9 of the center lock is coupled to the release mechanism 13 of the (e.g., lower) additional locking device 4 in such a way that, upon release, not only the additional bolts 11, 12, but also the center latch bolt 9 are automatically extended into the locking position in the manner described. For this purpose, the center lock 2 has a center lock chain 19 that is displaceable in the center housing 8 in the lock's longitudinal direction L. This chain is also referred to in practice as a connecting rod slider and is connected to or interacts with the connecting rods 5, 6. The center lock chain is displaced, for example, by actuating the handle, so that not only the center latch bolt 9, but also the additional locking elements 11, 12 are retracted. In the course of the Fig. 1With the automatic locking mechanism shown, both the additional locks 3, 4 and the center lock 2 reach the locking position. To achieve automatic locking of the center lock via the additional lock, the center lock chain 19 is positively coupled to the lower additional lock chain 17 in both directions via the drive rod 6.

[0032] The coupling of the center lock chain 17 with the center bolt 9 is effected via a rotatable, central driver 20, which acts on the bolt 9 via a pivoting latch lever 21. When the door leaf reaches the closed position according to Fig. 1 and thus in the area of ​​the release magnets 14 in the door frame, both the additional locking devices 3, 4 and the center lock 2 come into the Figures 2 to 5Locking position shown. With the lowering of the additional lock chain 17 of the lower additional lock, the associated lower drive rod 6 is also lowered, which in turn lowers the center lock chain 19 in the center lock. This pivots the central driver 20, which fully extends the center latch bolt 9 via the latch lever 21. The unlocking of the drive rod lock and consequently the retraction of all locking elements is carried out by actuating the actuating device and consequently the lock nut 15. This is always possible with a panic lock via the inner nut 15b. The prerequisite for the lock to also be able to be unlocked via the outer nut 15a is a corresponding activation via the activation device according to the invention. For this purpose, the Figures 6 and 7 referred to.

[0033] The activation device has a drive 24, which in the exemplary embodiment is designed as an electric motor drive and with which the actuating device can be activated, namely the nut 15 or the outer nut 15a can be coupled to the lock mechanism. Furthermore, the activation device has an (electronic) control 25, which is only indicated and is arranged, for example, on an electronic circuit board. The activation device also has a receiver for receiving an activation signal received from a transmitting device 30. For example, the locking system has a transmitting device, which can be, for example, a radio hand transmitter 30, with which a radio signal is transmitted as an activation signal to the receiver of the activation device of the lock. In this way, the lock nut 15 (or the outer nut 15a) can be activated via the radio hand transmitter 30.The outer nut 15a) can be remotely coupled to and uncoupled from the lock mechanism and in this way the access authorization can be controlled via the outside handle and consequently from the outside of the door.

[0034] Of course, it must be ensured that the lock nut 15 or 15a can only be activated with an authorized transmitting device 30. For this purpose, the activation device is equipped with a teach-in device, with which the activation device or its control unit 25 is placed into a teach-in mode in order to teach a transmitting device, e.g., a new radio handheld transmitter, to the activation device or its control unit and consequently to the specific lock. In order to be able to put the control unit 25 into teach-in mode, the teach-in device has a teach-in button 26, which can be actuated from the outside through the lock housing 8 and, in the exemplary embodiment, from the outside through the lock face plate 7. For this purpose, the lock face plate 7 is provided with an opening 32, through which the teach-in button 26 can be actuated with a suitable tool 31, e.g., a pin. Of course, it must be ensured that the teaching is only carried out by authorized persons.This is achieved according to the invention in that the learning device is equipped, in addition to the learning button 26, with a locking cylinder switch 27, which is actuated directly or indirectly by the locking cylinder 28 to select the learning mode. In the illustrated embodiment, the locking cylinder 28, also referred to as a profile cylinder, does not operate directly with the usual driver 33 on the locking cylinder switch 27, but rather via a slide 29, which is displaceably mounted in the lock housing 8 and which is part of the lock mechanism. With the help of the locking cylinder switch 27, the position of this slide 29 and thus also the position of the locking cylinder 28 can be queried.

[0035] According to the invention, the electronic control 25 of the activation device is configured and consequently programmed in such a way that the activation device is only put into learning mode when both the learning button 26 and the locking cylinder switch 27 are actuated (e.g. simultaneously). This is achieved, for example, by first actuating and holding the learning button 26, and by simultaneously actuating the locking cylinder switch 27 while the learning button 26 is being held. Both the learning button 26 and the locking cylinder button 27 are consequently connected to the control 25, so that the signals (of the two buttons or switches 26, 27) are evaluated by the control. If the predetermined requirements are met, the activation device is put into learning mode, so that, for example,By pressing a button on a radio hand transmitter 30, the radio hand transmitter can be taught to the lock 2 and consequently released for the lock 2.

[0036] In the Figures 6 and 7 Both the programming button 26 and the locking cylinder button 27 and consequently the PZ contact button are visible. The programming button 26, which is accessible through the opening 32 in the face plate 7, is in the functional position according to Fig. 6 inoperative, since the PZ slide 29 is in the spring-loaded, lower basic position, in which the PZ contact button 27 is not switched. In contrast, Fig. 7 The activation position. Turning the key and consequently the driver of the locking cylinder 28 in the opening direction against the spring force raises the profile cylinder slide 29, thus activating the profile cylinder contact button 27. In this position, the programming button 26, accessible through the lock face plate 7, is activated, thus starting the programming process for programming a new radio transmitter 30.

[0037] The teach-in button 26 can be a mechanical button or a contactless sensor. The same applies to the lock cylinder switch 27, which in the illustrated example is a mechanically activated button.

[0038] Furthermore, a power supply is provided for the lock 2, and in particular for the activation device. This can be wired via a supply cable connected to a power supply located, for example, on the frame side. Alternatively, a power supply or a rechargeable battery can be integrated into the door leaf or the lock, or connected to the lock.

[0039] Optionally, the power supply can be inductive, namely via a frame-side, inductive transmitter module and a door-side, inductive receiver module 34 with an inductive receiver antenna, which in the embodiment is arranged on the face plate 7 and / or on the lock 2

[0040] In summary, the measures described enable simple programming with a high degree of tamper-proofing. The inventive solution is, above all, very simple in design, since, for example, a mechanical cover for the programming button on the faceplate is no longer necessary. The solution can be implemented using known components or hardware, for example, if a switch or button for querying the functional position of the locking cylinder is already present for other functions. The invention can then be implemented by appropriately designing the control system and, consequently, the evaluation electronics.

[0041] The figures show, merely by way of example, an embodiment of a lock as a center lock in a multi-point locking system. The invention can also be implemented in principle with a mortise lock. Furthermore, the invention can be implemented with other types of multi-point locking systems, and in particular with multi-point locking systems without automatic release and / or without a panic function.

[0042] A lock is always provided with an actuating device that can be remotely activated and deactivated using a drive. This can, in particular, be a switchable lock follower.

[0043] Alternatively, the programming device according to the invention can also be implemented for a motor lock that has a receiver, so that, for example, a motor is triggered by a transmitter device to unlock and / or lock. Transmitter devices can also be programmed for such a lock, so that the inventive design of an activation device can also be implemented for a lock in which the actuating device itself is designed as a motor (for unlocking and / or locking the lock).
