Description

[0001] The invention relates to a lock, in particular a door lock, with at least a lock housing (e.g., attachable or fixed to a lock faceplate), 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 follower) for actuating (e.g., retracting) the locking element, an activation device with a drive arranged in or on the lock housing, by which the actuating device (e.g., the lock follower) can be activated (and, if necessary, deactivated), wherein the activation device comprises a controller (in particular for controlling the drive) and a receiver for receiving an activation signal received from a transmitter, wherein the activation device is equipped or connected with a teaching device with which the activation device or its controller can be put into a teaching mode in order to teach a transmitter to the activation device or its controller, wherein the teaching device comprises a teaching 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 multi-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 operating this locking element can be, for example, a lock follower that is rotatably mounted in the lock housing and into which at least one actuating pin for an operating handle, such as a lever handle or a panic bar, can be inserted. Preferably, the lock is such that the locking element(s) can be retracted by actuating the actuating device, such as the lock follower. The actuating device, such as the lock follower, can be activated by means of the activation device or the drive of the activation device and, for example,The lock cylinder is coupling, allowing the lock cylinder or, in the case of a split lock cylinder, one of the cylinder halves to be selectively coupled to or uncoupled from the lock mechanism. The drive mechanism can be, for example, an electric motor, resulting in an electrically coupling lock. Such a lock can be activated and deactivated remotely, for example, via a transmitter, thus controlling access authorization. If, for example, the lock cylinder or at least the outer cylinder of a split lock cylinder is deactivated via the activation device and consequently uncoupled from the lock mechanism, access from the outside is blocked. Access can be granted by activating and consequently coupling the lock cylinder or the outer cylinder to the lock mechanism. For this purpose, the activation device has, for example, a...a receiver integrated into 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 transmitter, e.g. a hand-held transmitter.

[0003] In practice, it is necessary to "pair" a transmitter, such as a radio remote control, with the lock and consequently with the lock's activation mechanism, so that the lock can only be activated with a paired and therefore authorized transmitter. To pair a (new) transmitter, the activation mechanism or its (electronic) control unit is put into a so-called "pairing mode." For this purpose, the lock has a pairing button that can be pressed from the outside through the lock housing. In practice, the pairing button is positioned in the lock housing in such a way that it can be pressed through the lock faceplate, for example, through an opening in the faceplate. Since the lock faceplate is only accessible when the door is open, this initially prevents a transmitter from being paired when the door is closed.Furthermore, to prevent an unauthorized person from programming a transmitter device with the door open, additional protective measures are in place in practice.

[0004] In practice, for example, one might encounter a mortise lock where the programming button is covered by a cover and therefore inaccessible to unauthorized persons. To remove this cover, a locking mechanism must be released using a key inserted into the lock cylinder. This ensures that the programming button can only be accessed with a key and consequently 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 on the remote control can be pressed to program the transmitter to the door lock.

[0005] The solution, which is well-established in practice, has generally proven effective. However, it can be improved.

[0006] Furthermore, EP 3 133 558 B1 describes a locking device, in particular a mortise lock, comprising a profile cylinder, an electronic control unit, and a radio module coupled to the control unit. A switching element is also provided, which is coupled to the control unit and can be actuated by turning the profile cylinder with a suitable key. The locking device enters a pairing mode when, with the switching element actuated, it is supplied with voltage, i.e., when it is switched from a de-energized to a energized state. This is achieved by first creating a de-energized state by removing an energy storage device, such as a battery.The profile cylinder then actuates the switching element that interacts with the control unit, while the locking mechanism remains de-energized. Next, the locking mechanism is energized with the switching element still activated. For this, the battery is reinserted, while the switching element remains closed by the key.

[0007] Based on the prior art, the invention aims to create a lock of the type described above which, with simplified construction and minimal risk of manipulation, enables easy programming of a transmitter device.

[0008] To solve this problem, the invention teaches, in the case of a generic lock of the type described above, that the learning device has, in addition to the learning button, a lock cylinder switch which can be actuated with the lock cylinder to select the learning mode (directly or indirectly), wherein the activation device or its control is arranged such that the activation device is only put into learning mode when both the learning button and the lock cylinder switch are actuated.

[0009] The cylinder switch can be a mechanical push button or, alternatively, a non-contact sensor, such as an optical, magnetic, or inductive sensor, which is actuated or triggered by the cylinder, also known as a profile cylinder. The cylinder switch can be actuated directly via the cylinder, for example, via the locking bolt. Preferably, however, the cylinder switch is actuated indirectly, by the cylinder operating the lock mechanism in the usual manner via a profile cylinder driver, also known as a locking bolt, on a slide that is coupled to or part of the lock mechanism, with the cylinder switch being located within the operating range of this slide and consequently being actuated by it.According to the invention, the control of the activation device is arranged such that a (new) transmitter device can only be taught if both the teaching button (e.g. through the lock faceplate) and the lock cylinder switch (e.g. simultaneously) are actuated.

[0010] The invention is based on the understanding that manipulation, namely the unauthorized programming of a transmitter, can be reliably prevented if the lock cylinder is integrated into the programming process and, consequently, programming is only possible with a key and therefore only by persons who possess a key for the respective lock. According to the invention, however, the use of the lock cylinder to remove a cover of the programming button is omitted, so that, according to the invention, an additionally required cover for the programming button can also be dispensed with. This is because, according to the invention, an "electronic release" of the programming button occurs, triggered by actuation of the lock cylinder, which in turn actuates a lock cylinder switch. The electronic control of the activation device therefore queries both the position or functional state of the programming button and the position or...The activation device only enters learning mode when both the learning button and the cylinder switch are pressed, thus generating an activation signal. This is achieved very simply through the electronic design and programming of the activation device's control unit, without complex mechanical components, and in particular without a mechanical cover for the learning button or a mechanical connection between the cylinder and the cover, or a mechanism for releasing the cover. In addition to the existing learning button, only a suitable switch or sensor is required to detect the position of the cylinder or a component coupled to the cylinder, such as a slider.Of particular interest in this context is the fact that many locks are already equipped with a so-called "PZ contact" and consequently 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 unit is modified and consequently programmed in such a way that the learning mode is only permitted if the query of the lock cylinder position yields a corresponding result.

[0012] Preferably, the activation device or its (electronic) control is configured, e.g., programmed, such that the activation device is only put into learning mode when the lock cylinder switch is actuated while the learning button is pressed or held. For example, to program a radio remote control or other transmitting device, the lock cylinder or key can first be turned in a predetermined direction, e.g., in the opening direction, and held in this position so that the lock cylinder switch is actuated. While the switch is held and thus remains actuated, the learning button is pressed, thereby starting the learning mode. The key can then be released, and the new transmitting device can subsequently be activated to program it. Alternatively or additionally, the activation device or its (electronic) control can be configured, e.g.,...B. programmed so that the activation device is only put into learning mode when the learning button is pressed while the lock cylinder switch is being operated or held. For example, to program a radio remote control or other transmitter, the learning button can first be pressed and held. While the button is held, and consequently while the learning button is pressed, the lock cylinder or key is then turned in a predetermined direction, e.g., in the opening direction, so that the lock cylinder switch is activated and the learning mode is started. The learning button can then be released, and the new transmitter can then be activated to program it. The control system can also be configured so that the sequence of the two activations of the lock cylinder switch and the learning button is irrelevant, as long as they are pressed simultaneously for a short time.

[0013] Alternatively, the control system can be configured or programmed so that one of the buttons or switches is pressed and released first, and then, within a specified time window, the other switch is pressed and released. According to the invention, starting the learning mode always requires both the activation of the learning button and the activation of the lock cylinder switch via the lock cylinder, either simultaneously or overlapping in time, or alternatively, sequentially or with a time delay.

[0014] The lock cylinder switch can be a mechanical push button actuated by the lock cylinder or by a lever or slider coupled to the lock cylinder. Alternatively, it can also be a non-contact switch or sensor, e.g., an optical, magnetic, or inductive sensor. It must always be ensured that a signal is generated that depends on the position of the lock cylinder and that is evaluated by the electronic control unit to perform the described logical query. According to the invention, the electronic control unit performs 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.

[0015] With a programmed transmitter, the activation device can be controlled, thereby activating the actuating device, e.g., the lock cylinder or one half of a cylinder, and consequently coupling it to or uncoupling it from the lock mechanism. In a preferred embodiment, the actuating device is designed as a lock cylinder into which at least one actuating pin for an operating handle, e.g., for a lever handle or a panic bar, can be inserted. Preferably, the lock cylinder can be actuated from both the inside and outside of the door, and at least one actuating pin for an operating handle, e.g., an outside lever handle and an inside lever handle or a panic bar, can be inserted into the lock cylinder on each side.The activation device is preferably designed as a coupling device, which has a coupling element that is adjustable with the drive and thus activatable for coupling the lock nut or at least one lock nut half (with the lock mechanism).

[0016] In a first embodiment, the lock follower is designed as a split lock follower with an outer follower associated with the outside of the door and an inner follower associated with the inside of the door. The inner follower is permanently coupled to the lock mechanism for engaging the locking element, for example, as a panic follower. The outer follower can be coupled to and uncoupled from the lock mechanism for engaging the locking element via the coupling 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 selectively controlled from the outside via the activation device by activating and selectively deactivating the outside handle, for example, using the transmitter.

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

[0018] The coupling element can be a coupling lever that can be moved from the deactivated uncoupling position to an activated coupling position and vice versa via the drive. The coupling lever can, for example, be designed as a pivoting coupling lever. The drive can be, for example, an electric motor or electromagnetic drive that moves the coupling element, e.g., the coupling lever, 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 faceplate that can be attached to a door leaf, wherein the lock or its lock housing is attached to the rear of the lock faceplate. In principle, the lock according to the invention can be a (simple) mortise lock. Preferably, however, a locking system in the embodiment described is claimed as a multi-point locking system with a multi-point locking mechanism, wherein the described lock with the activation device according to the invention is attached to the lock faceplate as a center lock. Additionally, at least one auxiliary lock is provided, which is coupled to the center lock via at least one drive rod. The auxiliary lock has an auxiliary housing and at least one auxiliary bolt adjustable within the auxiliary housing.

[0021] In a preferred embodiment, the lock is an automatically locking bolt lock that locks automatically when the door leaf is closed. For this purpose, a release mechanism is provided that automatically moves one or more locking elements into the extended locking position when the door leaf is closed. This release mechanism can, for example, be located in the auxiliary lock, so that the auxiliary bolt is automatically moved into the extended locking position when the door leaf is closed. 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 auxiliary lock in such a way that, upon release, both the auxiliary 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 in a multi-point locking system, has at least one locking element in addition to the cylinder. This locking element can be a conventional bolt and / or a spring-loaded latch. In one possible embodiment, the locking element is designed as a latch bolt, and consequently as a center latch bolt, which has a beveled actuating edge and is biased by a latch spring in the direction of an extended locking position.

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

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

[0025] The invention will now be explained in more detail with reference to the drawings, which merely illustrate exemplary embodiments. They show Fig. 1 a 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 object according to Fig. 1 In a first view, Fig. 3, the center lock according to Fig. 2 In a second view, Fig. 4, an additional locking mechanism of the connecting rod lock is shown. Fig. 1 In a first view, Fig. 5, the additional lock according to Fig. 4 In a second view, Fig. 6 shows a section of the central lock in a first functional position, and Fig. 7 shows the object. Fig. 6 in a second functional position.

[0026] The figures show an example of a locking system in the embodiment as a rod lock 1 with multiple locking. Fig. 1Figure 1 shows a multi-rod lock 1, mountable on a door leaf, which has a central lock 2 and two auxiliary locking points 3, 4, namely an upper auxiliary locking point 3 and a lower auxiliary locking point 4, which are coupled to the central lock 2 via locking rods 5, 6, namely an upper locking rod 5 and a lower locking rod 6. The central lock 2 and the auxiliary locking points 3, 4 are attached to the rear of a lock faceplate 7, which in turn is mounted on the door leaf. At least one strike plate is attached to a door frame (not shown), which has openings into which the locking elements of the multi-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 rod lock 1. The lock, or center lock 2, has a housing 8 (i.e., center housing 8) attached to the lock faceplate 7 and at least one locking element 9 adjustable within the housing 8, which is referred to as the center bolt 9. The two auxiliary locks 3, 4 each have an auxiliary housing 10 attached to the lock faceplate 7 and each have one or more auxiliary bolts 11, 12. The figures show only one exemplary embodiment in which each auxiliary lock has two locking elements, namely a latch bolt 11 and a swing hook bolt 12.

[0028] The figures merely illustrate an embodiment of a rod lock, which is referred to as an automatic lock. For this purpose, a release mechanism 13 is implemented in each of the auxiliary locking bolts 3, 4, which automatically moves the auxiliary bolts 11, 12 of the auxiliary locking bolts 3, 4 into the extended locking position when the door leaf is in the closed position. In this embodiment, the release is implemented as a magnetic release. Release magnets 14 are arranged in the area of ​​the door frame, e.g., in the respective strike plate. As soon as the door leaf reaches the closed position, the auxiliary locking bolts 3, 4 enter the effective range of the release magnets 14, thus triggering the automatic locking. The locking of the lock 1 occurs automatically, without requiring manual or electromechanical release by a user.The lock and door can be unlocked and opened by operating a handle from either the outside or the inside of the door. In the exemplary embodiment, a lock follower 15 is provided in the lock, and consequently in the central lock 2, as an actuating device. This follower can be actuated 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 on both sides.

[0029] This can be a bolt lock with a panic function, which is provided with a multi-part or split lock cylinder 15, comprising an outer cylinder 15a associated with the outside of the door and an inner cylinder 15b associated with the inside of the door. The inner cylinder 15b is, for example, permanently coupled to the lock mechanism for retracting the bolts 9, 11, 12, as a panic cylinder. The outer cylinder 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 comprising a drive 24 arranged in or on the lock housing, with which the actuating device, namely the lock cylinder 15 or at least the outer cylinder 15a, can be activated. This will be discussed in more detail below. Actuating the inner cylinder 15b preferably always results in a complete unlocking of the bolt lock, i.e.,All locking elements 9, 11, 12 are fully retracted to allow the door to be opened.

[0030] The design and function of the auxiliary locking devices 3, 4 are generally known. They can, for example, be auxiliary locking devices according to EP 3 372 757 B1. The auxiliary locking device 3, 4 has at least one locking element, which is particularly preferably a latch bolt 11. In the illustrated embodiment, the aforementioned swing hook bolt 12 is also provided. A locking chain 17, which is displaceable in the longitudinal direction L of the lock and is referred to as the auxiliary locking chain 17, is provided in the auxiliary housing 10. This chain is connected to the respective drive rod 5, 6 and allows the auxiliary bolt(s) to be retracted from the extended locking position to the retracted opening position (not shown) when the drive rod 5, 6 is moved in the unlocking direction.The auxiliary locking 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 located in or on the door frame or the strike plate, such that the locking element 18 releases the auxiliary locking chain 17, so that the auxiliary bolt 11, 12 is automatically moved into the extended locking position. The latch bolt 11 can also be retracted from the extended locking position or the (not shown) partially extended unlocked position to a (not shown) retracted open position by means of the locking chain 17. The (not shown) partially extended unlocked position, which can also be referred to as the basic position, is in which the spring-loaded latch bolt 11 projects a predetermined distance from the lock housing 10 and over the faceplate 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, automatic release occurs via the magnetic release, so that the latch bolt 11 moves into the fully extended locking position, which is in . Fig. 1 is shown. Additionally, the swivel hook bolt 12 is extended. This mechanism is generally known.

[0031] The center bolt 9 of the center lock is coupled to the release mechanism 13 of the (e.g., lower) auxiliary locking element 4 in such a way that, upon release, not only the auxiliary bolts 11, 12, but also the center bolt 9 are automatically extended into the locking position as described. For this purpose, the center lock 2 has a center lock chain 19, which is displaceable in the center housing 8 in the longitudinal direction L of the lock. This chain is also referred to in practice as a connecting rod slide 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 bolt 9, but also the auxiliary locking elements 11, 12 are retracted. In the course of the Fig. 1In the illustrated automatic locking mechanism, both the auxiliary locks 3 and 4 and the center lock 2 reach the locked position. To achieve the automatic locking of the center lock via the auxiliary lock, the center lock chain 19 is positively coupled to the lower auxiliary 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 follower 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 locks 3, 4 and the center lock 2 are engaged in the Figures 2 to 5The locking position shown is as follows. Lowering the auxiliary lock chain 17 of the lower auxiliary lock also lowers the associated lower drive rod 6, which in turn lowers the center lock chain 19 in the center lock. This pivots the central driver 20, which, via the latch lever 21, fully extends the central latch bolt 9. Unlocking the drive rod lock, and consequently retracting all locking elements, is achieved by actuating the actuating device and consequently the lock follower 15. This is always possible via the inner follower 15b in a panic lock. For the lock to also be unlocked via the outer follower 15a, corresponding activation via the activation device according to the invention is required. For this purpose, the Figures 6 and 7 referred.

[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 a (merely indicated) electronic control 25, which is, for example, arranged on an electronic circuit board. The activation device also has a receiver for receiving an activation signal received from a transmitter 30. For example, the locking system has a transmitter, which can be, for example, a radio transmitter 30, with which a radio signal is transmitted as an activation signal to the receiver of the lock's activation device. In this way, the lock nut 15 (or the outer nut 15a) can be activated via the radio transmitter 30.The outer nut 15a) can be remotely coupled to and uncoupled from the lock mechanism, thus controlling access authorization via the outside handle and consequently from the outside of the door.

[0034] It must, of course, be ensured that the lock cylinder 15 or 15a can only be activated with an authorized transmitter 30. For this purpose, the activation device is equipped with a learning device that puts the activation device or its control unit 25 into a learning mode in order to program a transmitter, e.g., a new radio remote control, to the activation device or its control unit and consequently to the specific lock. To put the control unit 25 into learning mode, the learning device has a learning 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 faceplate 7. For this purpose, the lock faceplate 7 is provided with an opening 32 through which the learning button 26 can be actuated with a suitable tool 31, e.g., a pen. It must, of course, be ensured that the programming is only carried out by authorized persons.According to the invention, this is achieved by equipping the learning device, in addition to the learning button 26, with a lock cylinder switch 27, which is actuated directly or indirectly by the lock cylinder 28 to select the learning mode. In the illustrated embodiment, the lock cylinder 28, which is also referred to as a profile cylinder, does not actuate the lock cylinder switch 27 directly with the usual driver 33, but rather via a slide 29, which is slidably mounted in the lock housing 8 and is part of the lock mechanism. The position of this slide 29, and thus also the position of the lock cylinder 28, can be queried using the lock cylinder switch 27.

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

[0036] In the Figures 6 and 7 Both the teach-in button 26 and the cylinder lock button 27, and consequently the PZ contact button, are identifiable. The teach-in button 26, accessible through the opening 32 in the faceplate 7, is in the functional position according to Fig. 6 inoperative, since the PZ slide 29 is in the spring-loaded, lower home 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 lock cylinder 28, in the opening direction against the spring force lifts the profile cylinder slider 29, thus switching the profile cylinder contact button 27. In this position, the programming button 26, accessible through the lock faceplate 7, is activated, so that the programming process for programming a new radio transmitter 30 is started.

[0037] The teach-in button 26 can be a mechanical push button or a non-contact sensor. The same applies to the lock cylinder switch 27, which in the exemplary embodiment is a mechanically actuated push button.

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

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

[0040] In summary, the described measures enable simple programming with a high degree of tamper resistance. The solution according to the invention is particularly simple in its design, as, for example, a mechanical cover for the programming button on the faceplate is unnecessary. The solution can be implemented with known components or hardware if, for example, a switch or button for querying the functional position of the lock cylinder is already present for other functions. The invention can then be realized by appropriately designing the control system and, consequently, the evaluation electronics.

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

[0042] A lock always includes an operating device that can be remotely activated and, if necessary, deactivated via an activation mechanism using a drive. This can, in particular, be a switchable lock cylinder.

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