Mortise lock for a door

Description

[0001] The invention relates to a mortise lock for a building door with a lock case according to claim 1.

[0002] Locks are known from the prior art. These locks can be electrified. However, the condition of the lock, particularly its electrical state, is unknown to installation or maintenance personnel.

[0003] German patent application DE 10 2011 002055 A1 discloses a lock with an optical indicator device. The indicator device is located on a narrow side of the lock and is directed towards an interior space. A through-opening in an actuating part of the door ensures that the light from the indicator device is visible when the door is closed.

[0004] It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a lock whose status is easily recognizable by assembly or maintenance personnel.

[0005] The aforementioned problem is solved by a mortise lock having the features of claim 1. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings.

[0006] According to the invention, the mortise lock includes an optical display device.

[0007] Because the mortise lock is equipped with a visual indicator, it is possible to visually display the lock's status. This status can preferably be an electrical state of the lock, and more preferably an electronic state.

[0008] The mortise lock according to the invention is designed for a building door.

[0009] According to the invention, the indicator device is arranged such that, when the lock is installed, the light from the indicator device is visible to the user when the building door is open. In the installed state, the lock is integrated into the door.

[0010] The lock includes a faceplate. When the building door is closed and the lock is installed, the faceplate is inaccessible to the user. The light generated by the indicator device is visible to the user from the faceplate.

[0011] The display device can be located on the faceplate, or light from the display device can be passed through the faceplate.

[0012] The faceplate, when the lock is installed in a building door, faces the door frame or door leaf. The faceplate may be accessible to the user when the door is open and the lock is installed.

[0013] The lock may include a bolt element. The bolt element may be movable between a position extended from the lock case and a position further retracted within the lock case. The bolt element may be designed as a bolt. In this case, the lock may be designed for a single-leaf door and / or a single-leaf door. The bolt element may be designed as a locking bar. In this case, the lock may be designed for a fixed-leaf door.

[0014] In the locked position, the bolt is extended from the lock case. In the unlocked position, the bolt is retracted into the lock case.

[0015] The lock may include a latch. The lock may be designed as a self-locking lock. A self-locking lock is designed to automatically engage when the building door is closed.

[0016] The lock may contain a tax trap.

[0017] The lock may include a nut for connection to a handle.

[0018] The lock can be designed as an anti-panic lock. With an anti-panic lock, it is possible to unlock the lock by operating the handle.

[0019] The lock can include an electromechanical actuator for electromechanically moving the lock into an unlocked and / or locked state. The actuator can, in particular, include an electric motor. The actuator can also include a gearbox. Preferably, the lock is in the unlocked position of the gearbox.

[0020] The lock can be connected to an electrical power supply. In particular, the lock can be connected to an external power grid. Electrical power can be drawn from an external power grid for the lock. The lock may include a connector for connection to an electrical power supply, especially an external power grid.

[0021] The display device may include a light source, and in particular may be designed as a light source. The display device may be switchable on and off.

[0022] Preferably, the indicator device is designed to emit different optical signals to represent different states of the lock. For this purpose, the indicator device can emit light of several colors and / or different flashing patterns.

[0023] For example, the display device can comprise a multi-color LED, such as an RGB LED, or correspond to a multi-color LED, such as an RGB LED. The display device can have several individual LEDs. The different colors can be generated, in part, by the simultaneous light emission of the individual LEDs of the multi-color LED. Different colors can be generated by varying the light output of the individual LEDs and / or by varying the light intensities of the individual LEDs.

[0024] It is conceivable that the display device can be controlled in such a way that light in at least two, preferably at least three, and particularly preferably at least four different colors can be emitted by the light sources. The different colors allow for a particularly clear indication of the various states of the lock.

[0025] To indicate different lock states, the indicator device can additionally or alternatively emit light continuously or in at least one flashing pattern. In particular, several flashing patterns can be provided. The type of light emission, i.e., the color and / or the flashing pattern, symbolically represents the lock state. Specifically, the user can associate the type of light emission with a lock state by referring to the operating instructions. When the following text refers to the indication of a lock state, it means a symbolic indication.

[0026] The lock may include an electronic device. This electronic device serves to control the display device. In particular, the electronic device may cause the display device to emit light in one of several possible colors or in a specific flashing pattern. The electronic device may be aware of the lock's state to be displayed. Based on this knowledge, the electronic device can control the display device accordingly.

[0027] The electronic device may include a processor, in particular a microprocessor. The electronic device may include a memory, in particular non-volatile memory. The electronic device may, for example, include a microcontroller, in particular be configured as a microcontroller. The memory of the electronic device may store which state of the lock is to be indicated by the display device. The memory of the electronic device may store which type of light emission from the display device is associated with which state of the lock.

[0028] The lock may be in several states that need to be displayed simultaneously. The electronic device's memory may store which state should be displayed first.

[0029] The electronic device can be located inside the lock case.

[0030] The lock can include at least one monitoring device. The monitoring device can be designed as a switch or a sensor. The monitoring device can be used to detect the position of a mechanical or electromechanical element of the lock. The monitoring device can be used to detect the position of the lock cylinder. The monitoring device can be located in the lock case. For example, a monitoring device can be designed to detect the locked state of the lock. For example, a monitoring device can be designed to detect the unlocked state of the lock. For example, a monitoring device can be designed to detect the position of the electromechanical actuator of the lock. For example, the monitoring device can be designed to detect the position of the cam. For example, the monitoring device can be designed to detect the position of a control latch of the lock.

[0031] The lock can additionally or alternatively be connected to a monitoring device for checking whether the building door is closed. This monitoring device is typically a sensor or switch.

[0032] Preferably, the lock includes several of the listed surveillance devices.

[0033] An electrical monitoring signal from the monitoring device is receivable by the electronic device. The monitoring device can be electrically connected to the electronic device for this purpose. The electronic device can use the monitoring signal to determine the lock's state. For example, the electronic device can use the monitoring signal from the monitoring device to detect the lock's locked state and determine its unlocked state.

[0034] If the lock incorporates multiple monitoring devices, the electronic device can, in particular, use these multiple monitoring devices to obtain information about the lock's state. For example, the electronic device can use the monitoring signals from devices for detecting the position of the spindle and for detecting the unlocked state to recognize the lock's state "just manually moved into the unlocked state".

[0035] The electronic device may learn the lock's state through an electrical signal or the absence thereof. For example, the electronic device can measure the voltage supplying power to the lock. The lock's state to be displayed can then correspond to this voltage level.

[0036] The lock can include at least one energy storage device, in particular a rechargeable energy storage device, e.g., a capacitor or an accumulator. The electronic device can determine the rechargeability of the energy storage device. The rechargeability can be determined, in particular, based on the charging and / or discharging rate of the energy storage device or on the electrical voltage in the charged state of the energy storage device. The state of the lock to be displayed can correspond to a state of the energy storage device.

[0037] The energy storage device can be located, in particular, in the lock case.

[0038] The lock can be connected to a bus system. The lock can communicate with other participants in the bus system via this system. The lock can be a participant in the bus system. A bus address can be assigned to the lock. The electronic device can be used for communication via the bus system. The electronic device can detect whether the lock is connected to the bus system. The displayed state of the lock can correspond to its connection status to the bus system. The display device can indicate whether the lock is a participant in the bus system. If connection to multiple bus systems is possible, the display device can indicate which bus system the lock is a participant in. Different possible bus addresses of the lock may be assigned to different optical light emission characteristics, in particular different colors and / or different flashing patterns.The display device can visually visualize the bus address in use.

[0039] The electronic device can detect a fault. The electronic device can cause the display device to show the fault. The displayed state of the lock can therefore correspond to a faulty state of the lock.

[0040] In particular, the electronic device can distinguish between multiple faults. The electronic device can instruct the display device to represent different faults differently. For this purpose, different types of light emission can be assigned to multiple faults in the electronic device's memory.

[0041] The electronic device can detect a fault based on at least one monitoring signal. For example, the electronic device may have activated the lock actuator to retract the bolt into the lock case. If the lock actuator does not move accordingly or the bolt remains extended, the electronic device detects a fault. Preferably, fault detection is based on monitoring signals from various monitoring devices.

[0042] The electronic device can detect a fault using an electrical signal. For example, the electronic device detects a fault if the measured electrical voltage does not correspond to a predefined voltage within a specified upper and / or lower limit. The state of the lock indicated by the display device corresponds to the state of "insufficient voltage supply".

[0043] Additionally or alternatively, the electronic device can detect a fault if the energy storage capacity does not match a specified value. The lock's status, as indicated by the display device, corresponds to the state of "insufficient energy storage."

[0044] The electronic device can detect a fault by the absence of an electrical signal. For example, the electronic device detects a fault if a message that should have been received by the electronic device via the bus system is missing. The state of the lock, as indicated by the display device, corresponds to the state "missing bus connection".

[0045] The lock can be designed, in particular, as a lock for a double-leaf door. The lock can interact with a counterlock for installation in a door leaf opposite the lock. Specifically, the lock is designed as a lock for an active leaf, and the counterlock is designed for a passive leaf. The lock and the counterlock can form a lock assembly. It can be provided that the electronic device receives an error message from a device of the lock assembly, in particular the counterlock, which is connectable to the lock, and the display device shows the error. The electronic device can control the display device to show the error.

[0046] To receive the error message, the electronic device can include a first communication means. A counterpart electronic device of the counter lock can include a second communication means. An error message sent by the counterpart electronic device of the counter lock via the second communication means can be received by the electronic device using the first communication means.

[0047] The electronic device may be aware of a specific electronic configuration of the lock. This electronic configuration may include at least one configuration value. This configuration value may be configured as at least one of the following options: a. stand-alone operation of the lock, b. operation in a bus system of the lock, wherein the lock is a participant in the bus system, c. operation in a selectable bus system, wherein several bus systems are available for selection, wherein the lock is a participant in the selected bus system, d. a bus address of the lock, e. switching on or off a terminating resistor, f. an opening duration, i.e., how long the bolt element is held in the retracted position in the lock case by the actuator.

[0048] It is conceivable that the electronic configuration includes several of the listed configuration values, e.g., a configuration value c and a configuration value d. Configuration values ​​a, b, and c are alternatives and cannot be present simultaneously in the electronic configuration. The configuration values ​​a, b, or c are referred to as the operating mode.

[0049] The electronic device can cause at least one configuration value to be displayed by the indicator device. This configuration value corresponds to the lock's state to be displayed. For this purpose, a specific type of light emission is assigned to the configuration value to be displayed in the electronic device's memory. This allows the indicator device to display configuration feedback to a user of the lock.

[0050] In particular, the configuration value can be displayed during normal operation of the lock. The lock's state can thus correspond to the electronic configuration, specifically a configuration value. The electronic device can store in its memory which configuration value is to be indicated by which color and / or flashing pattern. Different configuration values ​​can be displayed differently. For example, different colors and / or different flashing patterns can be provided for different configuration values. Preferably, the configuration value displayed during lock operation is indicated by continuous light emission.

[0051] The configuration can be adjusted through a configuration process.

[0052] Preferably, a configuration value is displayed when the electronic device starts up; more preferably, several configuration values, in particular all configuration values, are displayed at system startup. Most preferably, more configuration values ​​are displayed at system startup than during subsequent, especially normal, operation. The configuration values ​​can be displayed sequentially by the display device. This allows the user to gain a more accurate picture of the configuration at system startup than during operation. In particular, various different flashing patterns using different colors are provided at system startup. Specifically, a configuration value displayed at system startup can differ from, or be additional to, the configuration value displayed during the operation of the lock. For example,At system startup, the display may show a bus address or the activation or deactivation of a terminating resistor, whereas during normal operation, it indicates whether the lock is a participant in the bus system. Thus, the operating mode is displayed during normal operation.

[0053] It may be provided that the lock's configuration, particularly its electronic configuration, can be adjusted via a configuration process. The display device, in particular, visually represents the configuration process, at least in part. The configuration process serves to set the configuration. When setting the configuration via the configuration process, at least one configuration value, preferably several configuration values, is set.

[0054] It is conceivable that a configuration mode must first be initiated to set the configuration. In this configuration mode, it may be possible to set a configuration value. In particular, a configuration value can be selected from several available options. Outside of configuration mode, it is specifically prevented to set a configuration value, and especially to electronically save a configuration value. Initiating the configuration mode can correspond to the first step in the configuration process. Exiting the configuration mode can correspond to the final step in the configuration process. During normal operation of the lock, it is typically outside of configuration mode. The configuration mode can also refer to an electronic state of the electronic device.

[0055] During the configuration process, the initiation and / or termination of a configuration mode, a preset configuration value and / or a newly set configuration value can be indicated by the display device.

[0056] It is conceivable that at least one configuration menu, preferably several, is accessible in configuration mode. Ideally, it should be possible to switch between multiple configuration menus within configuration mode. The configuration menus can, for example, serve to structure the configuration values. Thus, each configuration menu could offer several configuration values ​​for selection. Setting a configuration value can be done within a configuration menu. During the configuration process, it should be possible to switch from one configuration menu to another. The change in the configuration menu can be visually indicated by the display device.

[0057] The display device may show a configuration value, particularly one just set, as configuration feedback during the configuration process. This provides the user with feedback on the value just set. Preferably, the display device can visually represent the configuration menu the user is currently in and / or a preset configuration value within that menu that the user can currently change.

[0058] It is conceivable that different colors are used for configuration values ​​within a configuration menu, particularly a main menu. Different flashing patterns may be used for configuration values ​​within another configuration menu, particularly a submenu. It is also conceivable that light with a flashing pattern is emitted from the display device in configuration mode.

[0059] It is conceivable that during operation of the lock, particularly outside of configuration mode, a set configuration value may be displayed by the indicator. The configuration value displayed during operation of the lock may correspond, in particular, to stand-alone operation (option a.), operation in the bus system (option b.), and / or the selected bus system (option c.). It is also conceivable that during operation of the lock, particularly outside of configuration mode, a configuration value set in the main menu may be displayed by the indicator.

[0060] The indicator device can be located in or on the lock case.

[0061] In particular, the indicator device is arranged in the lock case. The light emitted by the indicator device can be visible to a user through an opening in the lock case. This opening can be located, in particular, in the faceplate. Most preferably, the indicator device emits light through an opening used by another element of the lock. For example, the opening can be used for the bolt, the control latch, or the latch. It is also conceivable that the light from the indicator device is visible to the user through an opening in the lock case through which the bolt can be moved out of the lock case into the extended position.

[0062] Additionally or alternatively, the light from the display device can be made visible to the user via a light guide.

[0063] Preferably, the indicator device is switched off when the lock is in a closed position. In the closed position, the latch may be in an opening in the door frame or the fixed leaf.

[0064] Preferably, the indicator device is switched off when the lock is in a locked state. It is possible that the switch-off is omitted if the indicator device displays a faulty state. The faulty state may correspond to a faulty state of the lock and / or the mating lock. It is also possible that the indicator device is switched off when the lock is in a locked state and when the indicator device displays a non-faulty state, in particular a configuration value of the lock.

[0065] This prevents a malicious user from obtaining information about the configured settings, particularly via a bus system connected to the lock. For example, the indicator device can be deactivated if the monitoring device detects that the control latch has retracted into the lock case. Similarly, the indicator device can be deactivated if the monitoring device for the closed position of the door generates an electrical signal indicating that the door is closed.

[0066] The configuration process may be executable with the lock installed. For example, at least one monitoring signal, which can be generated by a monitoring device, can be used to perform the configuration process. In particular, electrical monitoring signals generated by an actuation action that can be performed with the lock installed are used for the configuration process. Specifically, a monitoring signal is used that can also be generated by an actuation action that moves the lock into the unlocked, locked, closed, and / or open state. For example, a monitoring signal that can be generated when the handle is actuated can be used.Additionally or alternatively, a monitoring signal can be used that can be generated when a locking cylinder, which can be connected to the lock, is actuated.

[0067] The indicator device may emit light visible to the user during the configuration process. In particular, the act of operating the device does not prevent the visibility of the light emitted by the indicator device. For example, the locking element may remain in the retracted position during the configuration process. Actuating the locking cylinder to perform the configuration process can always be done in the direction of moving the locking element into the retracted position.

[0068] It may be necessary to perform the configuration process with the door open so that the light of the display device is visible during the configuration process.

[0069] Preferably, the indicator device is visible throughout the entire configuration process while the lock is installed. In particular, movement of a lock component, especially the bolt or latch, that would obstruct the indicator device during the configuration process may be unnecessary, and / or the visibility of the indicator device may be ensured even if the component moves. It is conceivable, for example, that the lock is not moved into the locked position during the configuration process. This prevents the bolt protruding from the lock case from obstructing or preventing the visibility of the indicator device when the lock is in the locked position.

[0070] Further advantages, features, and details of the invention will become apparent from the following description, in which several exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. The drawings show: Fig. 1 is a schematic representation of a lock according to the invention, and Fig. 2 is a schematic representation to visualize a configuration method that can be carried out by the lock according to the invention.

[0071] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0072] In Figure 1A side view schematically shows a lock 200 according to the invention. It can be seen that some components of the lock 200 are completely arranged in a lock case 10, such as an electronic device 100. The electronic device 100 is electrically connected to monitoring means 110, in particular monitoring switches 110.

[0073] In addition to the lock 200 according to the invention, in Figure 1 A purely schematic representation of a locking cylinder 86 and a purely schematic representation of a handle 85 are also shown. The locking cylinder 86 can be inserted into an opening 82 of the lock 200. A follower 81 of the lock 200 can be connected to the handle 85.

[0074] The lock 200 comprises a bolt element 20. The bolt element 20 can be moved between a position extended from the lock case 10 and a position retracted into the lock case. When the bolt element 20 is in the extended position, the lock is in a locked state. When the bolt element 20 is in the retracted position, the lock 200 is in an unlocked state. The lock 200 can be moved from a locked state to an unlocked state by actuating the lock cylinder 86. By actuating the lock cylinder 86, the bolt element 20 can be moved from a locked to a retracted position via a mechanism of the lock 200. Figure 1 The indicated recess for a strike plate is moved outwards to unlock the door. The strike plate is not part of the lock 200 according to the invention.

[0075] The lock 200 includes a latch 70. The lock 200 is moved from a closed to an open state by actuating the handle 85. The handle 85 also actuates a mechanism within the lock 200, which unlocks and / or moves the latch 70. When the door is closed, the latch 70 may be located in a recess in the strike plate, shown schematically with a dashed line. In the open state, the latch 70 is retracted or released into the lock case 10, allowing it to retract into the lock case 10 when the door is opened. In the closed state, the latch 70 protrudes from the lock case 10. It is possible that movement of the latch 70 into the lock case 10 is blocked in the closed state.In one embodiment of the invention, the latch 70 is retracted into the lock case 10 when the lock 200 is open, and protrudes from the lock case 10 when the lock is closed. In an alternative embodiment of the invention, the latch 70 protrudes from the lock case 10 in both the open and closed states of the lock 200. In this case, retraction of the latch 70 into the lock case 10 is permitted when the lock is open, but prevented when the lock is closed. In this case, the latch 70 can be designed as a cross latch.

[0076] If the lock 200 is designed as a self-locking panic lock, it can be simultaneously moved into the locked and closed positions. The self-locking panic lock 200 can also be simultaneously moved into the unlocked and open positions.

[0077] The transition of the lock 200 from the closed state to the open state or the transition of the lock from the locked state to the unlocked state is to be regarded as an actuation action.

[0078] The lock 200 includes a control latch 83. Movement of the control latch 83 can serve the purpose of influencing the movement or blocking of the latch 70 and / or the bolt element 20. For example, the control latch 83 can be involved in a locking process, in particular a self-locking process.

[0079] The handle 85, the locking cylinder 86 and / or the control latch 83 can be operated from the outside by a user, even if the lock 200 is already installed in a door.

[0080] The locking cylinder 86 and the handle 85 can be operated even when the door is closed. This differs from a faceplate 11, which is only accessible when the door is open. The control latch 83 and / or the latch 70 and / or the locking element 20 can be located in this faceplate 11.

[0081] The electronic device 100 is connected to one or more electronic components of the lock 200, which serve as monitoring means 110 for monitoring the actuation. For example, a push-button contact 111 can detect an actuation action on the spindle 81, and thus, for example, the actuation of the handle 85. A cylinder contact 112 can, for example, serve to detect an actuation action on the locking cylinder 86. Furthermore, a control latch contact 113 can be provided to detect the depressing of the control latch 83 as an actuation action. During an actuation action, an electrical monitoring signal is generated by the respective monitoring means 110, which is received by the electronic device 100. Additionally, and not shown, another monitoring means can detect the extended position of the bolt element directly or indirectly.Additionally, and not shown, another monitoring device can detect the retracted position of the locking element indirectly or directly.

[0082] The lock 200 can include an electromechanical actuator (not shown) to move the lock 200 electromechanically into the unlocked state. The actuator can include an electric motor and a gearbox. The lock 200 can be moved into the locked and / or unlocked state by means of the electromechanical actuator. The electronic device 100 can also serve as a control device for actuating the electromechanical actuator. A further monitoring device (not shown) can detect the position of the actuator.

[0083] According to the invention, the lock 200 comprises a display device 120. The display device 120 can emit light. The display device 120 is designed as an RGB LED. For this purpose, the display device 120 can emit light of different colors and / or flashing patterns.

[0084] The display device 120 is electrically connected to the electronic device 100. The electronic device 100 can control the display device 120.

[0085] The indicator device 120 is arranged in the lock case 10. The light emitted by the indicator device 120 is perceptible to the user through an opening 21 in the lock case 10, through which the locking element 20 can be moved. The light from the indicator device 120 is thus visible through the strike plate 11. The light from the indicator device 120 is therefore only visible when the door is open or through a gap in the door. The light emitted by the indicator device 120 is more noticeable when the locking element 20 is in the unlocked state than when it is in the locked state.

[0086] When the door is closed, the light of the indicator device 120 is switched off. The electronic device 100 can detect that the door is closed, for example, by means of the control latch contact 113.

[0087] The electronic device 100 can transmit the status of the lock 120 to a central unit via an interface device 130. The interface device 130 can serve for electronic connection to a bus system (not shown). The lock 200 can be networked and controlled and / or monitored via the bus system. The interface device 130 can also serve for connection to an external power supply. The interface device 130 is designed as a connector.

[0088] The electronic device 100 can determine the state of the lock, for example, based on the electrical monitoring signals that the electronic device 100 has received. The state of the lock may also correspond to a faulty state.

[0089] The electronic device 100 can detect a faulty electrical condition of the lock, e.g., a faulty or missing power supply. The electronic device 100 can detect a faulty condition of the lock 200 by measuring an electrical voltage. The electronic device 100 can detect a lack of emergency power supply as a faulty electrical condition of the lock 200. An energy storage device (not shown) located in the lock case 10 can serve as the emergency power supply. The electronic device 100 can detect a faulty or missing connection to the bus system as a faulty electrical condition of the lock 200. For this purpose, the electronic device 100 can detect the absence of a message to be received via the bus system.

[0090] The electronic device 100 can send an error message via the interface device 130.

[0091] The electronic device 100 can cause the display device 120 to indicate the faulty state of the lock 200. Different faulty states are displayed differently. For example, in the case of a faulty power supply to the lock, the display device may flash red briefly several times and then flash once for a longer period in a different primary color. In the case of a faulty energy storage device, the display device 120 may flash red briefly several times and then flash once for a longer period in a different secondary color. A flashing light in a color other than red may indicate that the connection to the bus system is missing.

[0092] The lock 200 can be configured as a swing-leaf lock. In this case, in the locked and closed positions of the lock 200, the bolt element 20 and the latch 70 engage in openings of a counterlock for a fixed leaf instead of a strike plate. The electronic device 100 of the lock 200 can include a communication means by which the electronic device can communicate with a counterelectronic device of the counterlock (not shown) for the fixed leaf. The electronic device 100 can receive an error message via the communication means. The error message contains an error that has occurred in the counterlock. The display device 120 can visually represent the received error message. In particular, the representation of the error in the counterlock differs from the representation of an error in the lock by the selected color and / or the flashing pattern.

[0093] The user can visually monitor a configuration process 300 using the display device 120. In particular, the configuration process 300 serves to select settings or define configuration values ​​360 for the interface device 130.

[0094] The electronic device 100 is used to carry out the configuration process 300. The configuration process 300 is in Figure 2 To visually represent the configuration process 300, the electronic device 100 can control the display device 120 in such a way that light of different flashing patterns and / or different colors is emitted.

[0095] The electronic configuration of the lock 200 can be set using the monitoring devices 111 and 112, as will be described in more detail below. An actuation action on the locking cylinder 86 or on the handle 85, which generates an electrical monitoring signal, can serve as input for the configuration process.

[0096] The actuation action, which generates an electrical monitoring signal and serves as input for the configuration process 300, can also be performed in such a way that the lock 200 is not simultaneously moved into a locked, unlocked, open, and / or closed state. For example, the handle 85 can be actuated again in an opening direction while in the open state to generate the electrical monitoring signal for the configuration process 300, without affecting the state of the latch 70. The locking cylinder 86 can be actuated in the unlocking direction while the lock 200 is in the unlocked state to generate the electrical monitoring signal for the configuration process 300, without changing the state of the bolt element 20.

[0097] At least one input for the configuration process 300 can be subject to further conditions, e.g., at least one time-related condition. This can be provided by a timer device 140 as a further component of the electronics of the locking arrangement 200. The timer device 140 can be integrated into the electronic device 100 (not shown).

[0098] To allow the user to visually monitor the configuration process 300 using the display device 120, the operating actions are selected such that the locking element 20 remains in the lock case. Thus, with the locking element 20 retracted, the locking cylinder 86 is always rotated only in the unlocking direction.

[0099] During normal operation of the lock 200, i.e., outside of a configuration mode, the display device 120 shows the current operating mode of the lock 200. The lock 200 can be operating in standalone mode or in operation within a primary or secondary bus system. A bus system can be, for example, a CAN bus, a LON bus, and / or a DCW bus. The operating mode can be set via software. This means that no changes need to be made to the interface device 130 to switch from one bus system, e.g., a CAN bus, to another, e.g., a DCW bus. Likewise, no changes to the interface device 130 are necessarily required to switch from operation within a bus system to standalone operation.

[0100] The indicator device 120 can emit light in a different color for each operating mode. The operating mode indicator is interrupted if an error message needs to be displayed or if the door is closed.

[0101] When the electronic device 100 starts up, all 360 configuration values ​​are displayed by the display device 120. The 360 ​​configuration values ​​are displayed sequentially. For example, the operating mode is first displayed symbolically. If the lock 200 is operating in a bus system, the bus address is then displayed visually. For example, one bus address can be selected from a range of four. The display device 120 visually represents the selected bus address symbolically. If a terminating resistor needs to be set in bus operation, a visual signal indicating whether the terminating resistor is switched on or off is displayed after the bus address is shown.

[0102] In Figure 2Figure 1 schematically illustrates a configuration method 300 that can be carried out using the lock 200 according to the invention. First, a configuration mode 301 of the electronic device 100 is initiated. The configuration mode is an electronic, in particular software-based, state of the electronic device 100 in which at least one configuration value can be set. Outside of the configuration mode, setting a configuration value is prevented. This is intended to prevent an unintentional change of a configuration value by an actuation action. The initiation of the configuration mode 301 corresponds to a first input for the configuration process 300.

[0103] The initiation of configuration mode 301 can, for example, include a lock cylinder actuation as a first actuation action 311. The lock cylinder actuation 311 generates an electrical monitoring signal at the cylinder contact 112, which serves as input for the configuration process in the electronic device 100. The initiation of configuration mode 301 is linked to a further requirement. This further requirement for the initiation of configuration mode 301 corresponds to an actuation duration of the first actuation action 311, e.g., at least 10 seconds. This generates a monitoring signal of at least 10 seconds at the cylinder contact 112. A lock cylinder actuation that lasts longer than the actuation duration is not detected. Figure 2This is represented by reference numeral 311. This actuation duration can be determined, for example, via the timer device 140. This additional requirement prevents accidental switching to configuration mode, as a shorter cylinder actuation would only result in the door being unlocked or would have no effect in the unlocked state.

[0104] To further prevent accidental initiation of the configuration mode, the configuration process, and thus the initiation of the configuration mode, can only be carried out within a predefined time difference, e.g., 20 minutes, after a system start time of the electronic device 100. The time difference is determined by the timer device 140.

[0105] After successful initiation of configuration mode 301, the first actuation action 311, a second actuation action 320, and a third actuation action 310 can be used to generate further inputs for the configuration process 300. Each of the further actuation actions 310, 311, and 320 generates at least one monitoring signal from the corresponding monitoring means 110, which the electronic device 100 can use for the configuration process 300.

[0106] The second actuation action can correspond to an actuation of the handle 85. The third actuation action 310 can correspond to an actuation of the locking cylinder 86 within the actuation duration, i.e., a short actuation of the locking cylinder 86.

[0107] The configuration mode includes several configuration menus 330, 340, 350, 370. In each configuration menu 330, 340, 350, 370, at least one configuration value 360a, 360b, 360c, 360d, 360e, 360f, 360g, 360h, 360i, 360j, 360k, 360l, 360m can be set. For the configuration values ​​360a, 360b, 360c, 360d, 360e, 360f, 360g, 360h, 360i, 360j, 360k, 360l, and 360m, the reference symbol 360 is used collectively below, unless a more precise reference symbol is necessary. The configuration is set by setting at least one configuration value 360, preferably by setting multiple configuration values ​​360. In particular, the configuration is set by setting at least two configuration values ​​360 from at least two configuration menus 330, 340, 350, and 370.

[0108] The first configuration menu, 330, serves as the main menu. From main menu 330, users can navigate to further configuration menus 340, 350, and 370. These additional configuration menus function as submenus. Switching between configuration menus 330, 340, 350, and 370 requires an action. In other words, switching between these menus is triggered by generating a monitoring signal.

[0109] Submenu 340 contains configuration values ​​360d, 360e, 360f, and 360g, which correspond to configuration value 360b set in main menu 330. Submenus 350 and 370 contain configuration values ​​360h, 360i, 360j, 360k, 360l, and 360m, which correspond to configuration value 360c set in main menu 330. Submenu 340 can only be accessed if configuration value 360b is already set in the main menu. Submenus 350 and 370 can only be accessed if configuration value 360c is already set in the main menu. For example, selecting the second configuration value 360 ​​b and subsequently actuating cylinder 310 results in a change to configuration menu 340. Selecting the third configuration value 360c and subsequently actuating cylinder 310 results in a change to configuration menu 370.

[0110] Each configuration menu 330, 340, 350, 370 of the exemplary implementation of the Figure 2 Each configuration menu includes 360 alternative configuration values. Only one of the configuration values ​​360 can be selected and set from the configuration values ​​330, 340, 350, 370 of a configuration menu.

[0111] Each configuration menu 330, 340, 350, 370 includes a preset configuration value 360. Setting a configuration value 360 ​​that differs from the preset configuration value 360 ​​within a configuration menu 330, 340, 350, 370 requires an action and thus the generation of a monitoring signal.

[0112] To simplify the configuration process 300 for the user, the same action can always be required to switch between configuration menus. This action could, for example, correspond to the third action 310. Within configuration menus 330, 340, 350, and 3370, the same action can always be used to set configuration value 360. This action could, for example, correspond to the second action. Thus, switching between configuration menus 330, 340, 350, and 370 can be achieved by briefly pressing the locking cylinder 86 and thus the cylinder contact 112. Within each of configuration menus 330, 340, 350, and 370, switching from one configuration value 360 ​​to the next can be achieved by pressing the handle 85 and thus the push-button contact 111.

[0113] In the main menu 330, for example, an operating mode for the lock 200 can be set. A first configuration value 360a could be, for example, stand-alone operation, a second configuration value 360b the use of a first bus system, and a third configuration value 360c the use of a second bus system. For example, configuration value 360a is set as the default. Upon the first handle activation 320, the system switches to configuration value 360b and sets that value. Upon a second handle activation 320, the system switches to configuration value 360c and sets that value. A third handle activation returns the system to the first configuration value 360a.

[0114] In configuration menu 340, parameters for using the first bus system can be set. For example, configuration value 360d can correspond to a first bus address, configuration value 360e to a second bus address, configuration value 360f to a third bus address, and configuration value 360g to a fourth bus address. Switching between configuration values ​​360d, 360e, 360f, and 360g is possible by actuating the handle and by generating a monitoring signal at push-button contact 111.

[0115] In configuration menu 370, parameters for using the second bus system can be set. For example, configuration value 360j can correspond to a first bus address, configuration value 360k to a second bus address, configuration value 360l to a third bus address, and configuration value 360m to a fourth bus address. Switching between configuration values ​​360j, 360k, 360l, and 360m is possible by actuating the handle and generating a monitoring signal at push-button contact 111.

[0116] In configuration menu 350, configuration values ​​360h and 360i can be used to determine whether a terminating resistor should be used for the second bus system. Switching between configuration values ​​360h and 360i is possible by actuating the handle and generating a monitoring signal at push-button contact 111.

[0117] The configuration mode can then be ended from any menu item 330, 340, 350, 370 (marked with reference 390) by means of a further actuation action, for example a cylinder actuation 311 for a predetermined actuation duration, e.g. for at least 10 seconds.

[0118] Properly exiting configuration mode saves the configured values, which are then used as the configuration for the lock's operation. If configuration mode is not exited by entering 390 within a specified time period, such as 5 minutes, the configured values ​​will not be used for the lock's operation. Furthermore, configuration mode may automatically exit after a specified timeout, such as 5 minutes, following its initiation.

[0119] It is possible that during configuration process 300, i.e., in configuration mode, remote control of the locking device 200, e.g., via the bus system, is not possible; remote control is therefore deactivated in configuration mode. For example, motor activity of the actuator of the locking device 200 may also be prevented in configuration mode. In some cases, the configuration mode may thus resemble or correspond to the stand-alone operation of the locking device 200, in which signals at the input of the interface device 130 are ignored.

[0120] It may be possible that after successful initiation of the configuration mode, the configuration process 300 always continues in the first configuration menu 330 for selecting the operating mode.

[0121] It may be possible that each actuation of button 320 cycles through the configuration values ​​360 within a configuration menu 330, 340, 350, 370, in such a way that after a complete cycle of all configuration values ​​360 of a configuration menu 330, 340, 350, 370, the cycle starts again at the first configuration value of this configuration menu 330, 340, 350, 370.

[0122] To indicate to the user which configuration value is currently selected, the display device 120 can be used.

[0123] For example, depending on the currently selected configuration value 360, different displays can be shown, e.g., the display device 120 can light up in different colors and / or flash. For example, when the first configuration value 360a is selected, the display device 120 can emit an orange light signal; when the second configuration value 360b is selected, the display device 120 can emit a blue light signal; and when the third configuration value 360c is selected, the display device 120 can emit a yellow light signal. Furthermore, it can be provided that in the second configuration menu 340 or in configuration menu 370, the current bus address selection is indicated by a flashing code of the display device 120. Similarly, in configuration menu 350, the selected configuration value 360h or 360i can be indicated by a flashing code.

[0124] When switching between configuration menus 330, 340, 350, and 370, the preset configuration value 360 ​​of the selected menu is immediately displayed. The display device 120 thus visually indicates the change between configuration menus 330, 340, 350, and 370.

[0125] After configuration mode 390 has ended, the configuration can be permanently stored in a memory device (not shown) of the electronic device 100. The end of configuration mode 390 can also be signaled by the display device 120, for example, by the output of a light signal of a specific color.

[0126] Furthermore, it may be possible that after the configuration process has ended, the display device 120 will also signal the selected operating mode outside of the configuration mode, e.g. by the color code described above, i.e. by outputting a light signal in a color corresponding to the selection of the configuration value 360.

[0127] The initiation of configuration mode is indicated by the display device 120 by switching from displaying the selected operating mode to displaying the preset configuration value 360a, 360b, 360c of the main menu 330. If the operating mode is selected in the main menu 330, the operating mode displayed before the initiation of configuration mode corresponds to the operating mode preset in the main menu. To visually represent the initiation of configuration mode, the display device 120 modifies the display of the operating mode. For example, the display device 120 can represent the operating mode before the initiation of configuration mode by continuously emitting light of one color, while after the initiation of configuration mode, the operating mode is represented by a flashing light of the same color.

[0128] The exit from configuration mode is indicated by the display device 120 by a color and a flashing pattern, regardless of which configuration menu 330, 340, 350, 370 the configuration mode was exited from.

[0129] The following describes two example configuration settings: Before starting configuration process 300, the lock 200 is in stand-alone operation. The indicator 120 glows orange when the door is open. The configuration mode is initiated by pressing the lock cylinder 86 for at least 10 seconds. In configuration mode, the indicator 120 begins to flash orange. Pressing the handle 320 causes the indicator 120 to flash blue, signaling that function value 360b of the first configuration menu 330 is now selected. Pressing the handle again 320 sets function value 360c to operation in a second bus system. The indicator 120 indicates this by flashing yellow. Briefly pressing the lock cylinder 86 switches to configuration menu 370. The bus address for the second bus system can now be set.The indicator 120 flashes green once periodically to indicate that function value 360j, and thus the first bus address, is the default setting. Pressing the push button 320 twice sets function value 360l, and thus the third bus address. This setting is indicated by the indicator 120 flashing green three times periodically. A short press of the lock cylinder 310 accesses the configuration menu 350. Here, function value 360h can be used to activate the terminating resistor, and function value 360i can be used to deactivate it. The indicator 120 glows green to indicate that the terminating resistor is currently activated, meaning function value 360h is preset. If function value 360i were preset, the indicator would glow red.The user wishes to retain the function value 360h and ends the configuration mode by operating the lock cylinder 311 for at least 10 seconds, thereby adopting the set configuration values ​​360 as the configuration for the operation of the lock 200. The end of the configuration mode is indicated by a green light from the indicator device 120 and is shown in . Figure 2 represented by reference numeral 390.

[0130] In a different configuration process 300, which initially proceeds identically to the previously described procedure until the user switches to configuration menu 350, the user discovers in configuration menu 350 that they have set the wrong bus address and that the first bus address for the second bus system should have been set. Instead of exiting configuration mode in configuration menu 350, the user switches back to configuration menu 330 by briefly actuating the lock cylinder 310. A yellow flashing light indicates that the user is in configuration menu 330 with the preset function value 360c. Since the correct configuration value 360c is already set in configuration menu 330, the user switches to configuration menu 370 by briefly actuating the lock cylinder again 310.Here, the user can change the bus address from the third bus address to the first bus address, and thus from function value 360l to function value 360j, by pressing handle 320 twice. This is indicated by the display device 120 through a single, periodically recurring green flash. The user can exit configuration mode from the configuration menu 370 by pressing the lock cylinder for at least 10 seconds (311).
