Description

Method for a lock device

Technical Field

The present invention relates to a method for a lock device. Furthermore, the invention relates to a locking system having a locking device, wherein the locking device comprises a lock for a movable leaf and a counter lock for a stationary leaf, wherein the lock comprises at least one latching element, wherein the latching element engages in an opening of the counter lock in a locking position of the latching element, wherein the counter lock comprises at least one latching lever connection for connecting a first latching lever, wherein the lock comprises an electromechanical lock actuator for moving the latching element, wherein the counter lock comprises an electromechanical counter lock actuator for moving the first latching lever.

Background

A locking system with a locking device with a lock for a movable door leaf and a counter lock for a fixed door leaf is known from EP 2749721B 1. A motor provided in the counter lock first moves the deadbolt back into the lock. Subsequently, the electric motor moves the latch lever into a position in which the fixed leaf door is unlocked. The disadvantage of this is that the counter lock requires different mechanical elements for the mechanical and electrical movement of the bolt and the bolt rod.

Disclosure of Invention

The object of the present invention is to provide an improved solution for the electromechanical locking and/or unlocking process of a locking system, in particular to eliminate the above-mentioned disadvantages at least in part.

The above object is achieved by a method for a lock device and by a locking system. Further features and details of the invention are taken from the description and the drawings. The features and details described in connection with the method of the invention are obviously also applicable here to the features and details described in connection with the locking system of the invention and vice versa, so that the disclosure in respect of the individual inventive aspects are always or can be cited with respect to one another. In particular, the method implemented with the locking system according to the invention also protects the locking system with which the method according to the invention for a lock device can be implemented.

This object is achieved in particular by a method for a lock device, wherein the lock device comprises a lock for a movable leaf door and a counter lock for a fixed leaf door. The entire door, including the movable leaf and the fixed leaf, can form a building door, in particular an escape door, a fire door, etc.

The lock comprises at least one latching element, wherein the latching element engages in an opening of the counter lock in a locking location of the latching element. The latching element can be disengaged from the opening, in particular in an unlocking position of the latching element. In this case, the lock and the counter lock can be arranged in particular adjacent to one another, so that the latching element can engage in an opening of the counter lock in the unlocking position. Advantageously, the latching element is movable in translation between the locking position and the unlocking position.

The counter lock comprises at least one, in particular first, latch rod connection for connecting a first latch rod.

The counter lock comprises an electromechanical counter lock actuator, in particular an electric motor, for moving the first locking lever and/or the first locking lever joint.

According to the invention, the lock comprises an electromechanical lock actuator, preferably an electric motor, for moving the latch element. To move the first latch rod, a mating lock actuator is activated such that the lock actuator at least partially causes movement of the latch member. In other words, to move the first latch lever, the counterpart lock actuator is activated, so that the lock actuator at least partially takes over or causes a movement of the latch element. The activation of the counter-lock actuator for moving the first locking lever causes the lock actuator to at least partially cause a movement of the locking element, in particular when the locking device is transferred into the unlocked and/or locked state. In other words, for the locking device, i.e. the locking process and/or the unlocking process of the lock and the counter lock, not only the counter lock actuator but also the lock actuator is activated.

The lock is in particular in the locked state when at least the latch element is in the locking position. The lock is in particular in the unlocked state when at least the latch element is in the unlocking position.

The lock can include a lock housing. The mating lock can include a mating lock housing.

Preferably, the first latch lever is movable by means of a first latch lever joint. Thus, the pair of lock actuators causes the first pair of lock actuators to move the first latch rod by: the first latch rod joint is moved in coordination with the lock actuator. The first latch lever is movable to a moved-out position and a moved-in position. In the removed position, the first latch lever is in engagement with the first locking element. The first locking element is located in a door frame, in a floor or in a wall. The first bolt bar is thus used in the moved-out position for locking the fixed leaf door. In the moved-in position, the first latch lever is out of engagement with the locking element. Thus, the locking by the first latch lever is cancelled in the moved-in position. The first latch rod joint moves in conjunction with the first latch rod. If the first latch lever is in the removal position, the first latch lever joint is correspondingly in the removal position. If the first latching lever is in the retracted position, the first latching lever connection is correspondingly in the retracted position. The first latch rod connection can be arranged in a mating lock housing. Thus, the disclosure with respect to the movement and/or positioning of the first latch lever in/into the run-in position and/or the run-out position likewise includes the disclosure with respect to the movement and/or positioning of the first latch lever joint in/into the run-in position and/or the run-out position.

The counterpart lock is in particular in the locked state when at least the first lock bar joint is in the removal position. The counterpart lock is in particular in the unlocked state when at least the first lock bar connection is in the run-in position. When the latching element is in the unlocking position, the counter lock is preferably in the unlocked state.

When the lock device is converted into the unlocked state, the lock and the paired lock are converted into the unlocked state. When the lock device is transferred to the locked state, the lock and the counterpart lock are transferred to the locked state. The transformation of the lock device into the unlocked state is referred to as an unlocking process of the lock device. The transformation of the lock device into the locked state is referred to as a locking process of the lock device. Thus, during unlocking of the lock device, at least the latching element is moved into the unlocking position and the first latching lever connection is moved into the insertion position. During locking of the lock device, at least the latching element is moved into the locking position and the latching lever connection is moved into the removal position.

Since the lock device comprises an electromechanical lock actuator in addition to the electromechanical counterpart lock actuator, the movement effect of the latching element and the movement effect of the first lever connection can be distributed to the counterpart lock actuator and the lock actuator. Since the lock actuator at least partially causes the movement of the latch element, the lock actuator can assist and/or supplement the counterpart lock actuator during the locking and/or unlocking of the lock device. Thereby, there is no need to decouple potential movements of the latching lever joint and of the latching element which are electromechanically caused by the mating lock. Instead, it is possible to mechanically couple the movement of the latching element, in particular into the unlocking position, and the movement of the latching element joint, in particular into the retracted position, caused by the mating lock to one another in a simple manner. The electromechanical resulting movement of the latching bar connection can here be dependent on the same counter-lock mechanism as the mechanical resulting movement of the latching bar connection. Furthermore, via the mutual cooperation performed by the lock actuator and the counter lock, the locking and/or unlocking process of the lock device can be performed in a secure and reliable manner.

In order to activate the counter lock actuator and/or the lock actuator, a control device, in particular electronic, is advantageously provided, which effects the activation of the counter lock actuator in such a way that the lock actuator at least partially causes the movement of the latch element. To achieve this, the control device can be at least partially electrically connected to the lock actuator and/or the counter lock actuator and/or connected to the lock actuator and/or the counter lock actuator via a radio.

The mating lock preferably includes at least one second latch bar joint for connecting to a second latch bar. Preferably, the second latching lever is movable by means of a second latching lever joint. Thus, the mating lock actuator moves the second latch in a manner that: the second latch rod joint is moved by the mating lock actuator. The second latch lever is movable into a moved-out position and a moved-in position. In the moved-out position, the second latch lever is in engagement with the second latching member. The second latching member is located in a door frame, in a floor or in a wall. The second bolt bar is thus used to lock the fixed leaf door in the moved-out position. In the moved-in position, the second latch lever is out of engagement with the latching element. Thus, the locking by the second latch lever is cancelled in the moved-in position. The second latch rod joint moves in conjunction with the second latch rod. If the second latch lever is in the removal position, the second latch lever joint is correspondingly in the removal position. If the second latching lever is in the insertion position, the second latching lever connection is correspondingly in the insertion position. The counter lock can include a second latch bar joint. The second latch rod joint can be arranged in a mating lock housing. Thus, the disclosure with respect to the movement and/or positioning of the second latching lever in/into the run-in position and/or the run-out position likewise includes the disclosure with respect to the movement and/or positioning of the second latching lever joint in/into the run-in position and/or the run-out position.

For example, the first latch bar can correspond to the lower latch bar and the second latch bar can correspond to the upper latch bar. The movements of the first and second latch rods into the moved-out and moved-in positions can be opposite to each other. The movement of the first latch rod joint and the second latch rod joint can be at least partially coupled. It is therefore conceivable that both the first and the second latch lever are moved from the respective moved-out position into the respective moved-in position when the counter lock is transferred into the unlocked state. When the mating lock is transferred to the locked state, the first and second latch levers move from the respective moved-in positions to the respective moved-out positions. The first and second latch bar joints move accordingly. If it is disclosed below that the first latch lever is moved from the moved-in position into the moved-out position or vice versa, the second latch lever can also be moved from the moved-in position into the moved-out position and vice versa.

It is possible for the force accumulator to be tensioned in the extended position of the first and/or second locking lever. It is conceivable that the first and/or second latch lever can be moved into the extended position by means of the energy store when the fixed leaf door is closed. The counter lock can thus be designed to be self-locking.

For example, the spring element is tensioned in the moved-in position of the upper latch lever. The spring element can thus correspond to an accumulator. The spring element can be arranged inside or outside the counter lock housing. The upper locking bolt can be held in the retracted position by a triggering element, for example a switch lock, when the spring is tensioned. When the fixed door is locked, a trigger element, such as a switch lock, releases the movement of the upper latch rod. The upper latching lever is then moved into the removal position by means of the spring element.

The mating lock can include a mating lock mechanical element.

The lower latch lever can be moved into the removed position by the force of a mating lock spring. The counter lock spring can be arranged in particular in a counter lock housing.

The latching system can include first and/or second latch bars. Alternatively, the locking system may be connected to the first and/or second latch bar.

By means of the mating lock actuator, the first and/or second latching lever connection can be moved into the insertion position. In particular, the at least one energy store, in particular a spring and/or a counter lock spring, is tensioned if the first and/or second latch rod connection is moved into the insertion position by the counter lock actuator.

The counter lock actuator can act at least on the counter lock mechanical element in order to move the first and/or second latching lever joint into the run-in position. In particular, the counter lock actuator can act on the counter lock mechanical element via the counter lock transmission.

It is conceivable that the counter lock actuator acts on the counter lock mechanical element such that the first and/or second latching lever connection is moved in the insertion region, in particular against the force of the force accumulator. In this case, the counter lock gearing is in the unlocked position. If the counter lock actuator is in the unlocked position, the first and/or second latch rod joint is preferably prevented from being transferred to the removal position. If the counter lock actuator is in the release position, the counter lock actuator preferably releases the first and/or second latch lever connection into the removal position. In the unlocked position, the pairing lock transmission prevents self-locking of the pairing lock.

Typically, shortly after the pairing lock is transferred to the unlocked state by means of the pairing lock actuator, the pairing lock is transferred to the locked state again. A permanent unlocking can be desirable if it is desired to open the fixed leaf door particularly quickly and frequently during daytime operation. In this case, the following states are considered as permanent unlocking of the lock: in this state, the counter lock actuator remains in the unlocked position until the control device receives a signal: the permanent unlocking of the counterpart lock is to be undone. The control device then moves the counter lock gear into the release position.

It is possible that the mating lock actuator causes the first and/or second latch rod joint to move to the removal position. To this end, the counter lock actuator can act on the counter lock mechanism. Alternatively and preferably, the mating lock actuator can allow the first and/or second latch rod joint to move to a removal location. For example, the pairing lock transmission in the release position can allow the pairing lock to be transferred into the locked state, in particular by means of at least one energy store.

It is conceivable that the counter lock transmission is in operative connection with the counter lock mechanical element in the unlocked position. In the release position, the counter lock transmission is in an operative connection with the counter lock mechanical element, such that the force of the at least one energy store can move the first and/or second latch rod connection into the removal position. For example, the cam of the mating lock actuator can be operatively connected to the protrusion of the mating lock mechanical element.

The counter lock can comprise an actuating element. The actuating element can be designed as a toggle lever. The actuating element can be connectable to the handle and/or the emergency lever. In addition or alternatively, the actuating element can be designed as a lock cylinder. The mating lock, preferably the lock device, can be mechanically transferred into the unlocked state by means of the actuating element. In other words, the latching element can be moved into the unlocking position and the first and/or second latching lever connection can be moved into the insertion position by means of the actuating element of the counter lock. The fixed leaf door, in particular the fixed leaf door and the movable leaf door, can thus be mechanically transferred from the unlocked state. The pairing lock can therefore be designed as an emergency pairing lock (Anti-Panik-Gegenschloss).

It is envisaged that the counter lock comprises a latch member operator for moving the latch member to the unlocking position. The actuating element is moved, in particular, by a handle or a panic lever when the actuating element is actuated. The latch element can be moved from a locking position to an unlocking position by movement of the latch element actuation part. Thus, the latching element manipulator serves to mechanically undo the locking by the latching element via the counter lock. In the retracted position of the latch element manipulation member, the latch element can be in the locking position. The latch member is in the unlatched position if the latch member operator is in the active position. In particular, the locking element actuation is designed in such a way that the locking element is moved out of the counter lock housing by being moved from the retracted position into the active position. It is conceivable that the movements of the latching element manipulation and of the first and/or second latching lever joint are coupled at least partially, in particular via a counter lock mechanical element.

It is possible that the movements of the second latching lever connection and of the latching element actuation part are coupled to one another. It is possible that the movements of the first and second latching lever connections are coupled to one another when they are moved into the insertion position. It is possible that the movement of the first latching lever connection to the removal point is not directly coupled to the movement of the second latched lever connection to the removal point and/or to the movement of the latching element actuation part to the active position. In contrast, it is possible to release the movement of the first latching lever connection into the removal position when the second latching lever connection is moved into the removal position and/or the latching element actuating element is moved into the active position, but to carry out the movement of the first latching lever connection by means of the energy store, in particular in conjunction with a locking spring.

The latching element can be designed as a latch. It is envisaged that the lock comprises a bolt. The bolt can be lockable. If the bolt is locked, the bolt can function as the second latch element. It is possible to unlock the bolt simultaneously with the movement of the latch element from the locking position to the unlocking position. It is conceivable for the unlocked bolt to move into the lock housing during the opening movement of the door. Preferably, the bolt can be configured as a cross bolt.

It is possible that the counterpart lock does not have a bolt actuating element. Instead, the deadbolt can be unlocked simultaneously at the same time as the latch elements are moved to the unlocking position. In particular, the movement of the bolt into the lock housing can be released simultaneously with the movement of the latch element into the unlocking position.

The lock actuator is configured to act on the lock mechanism member to move the latch member to the unlatched position. It is conceivable that the lock actuator acts on the lock mechanical element such that the latching element is held in the unlocked position, in particular against the force of the lock spring. In this case, the lock actuator connected to the lock actuator is in the unlocked position. When the lock is released for a long time, the lock transmission device is kept at the unlocking position until the control device receives a signal: and releasing the lock after the pin lock is removed. Permanent unlocking of the lock and of the counterpart lock is understood to be permanent unlocking of the lock device.

It is possible that the lock actuator causes the movement of the latch member to the locking position. For this purpose, the lock actuator acts on the lock mechanism. Alternatively and preferably, the lock actuator is configured to allow the latch member to move to the locking position. For example, the lock actuator can be brought out of operative connection with the lock mechanism element, so that the lock mechanism element can move the latch element into the locking position by the force of the spring.

Preferably, it can be provided that the lock actuator and the counter-lock actuator are activated in order to transfer the lock device into the unlocked state. The unlocking process of the lock device is therefore carried out in particular by means of the lock actuator and the counter lock actuator.

The lock actuator and the mating lock actuator can be activated such that the latch member remains spaced from the latch member operator while the latch member is electromechanically moved to the unlatched position. In this way, it is possible in particular to realize a movement of the latching element without electrical power of the mating lock actuator. The lock actuator effects movement of the latch member to the unlocking position without the aid of a mating lock actuator. If the lock actuator and the counterpart lock actuator can be activated such that the latching member remains spaced apart from the latching member operator, the latching member operator does not assist in moving the latching member to the unlocking position. The movement of the latching element into the unlocking position is effected exclusively by the lock, in particular by the lock actuator. Preferably, this is achieved by activating the lock actuators prior in time to pairing the lock actuators.

Thus, for example, at least three or exactly three solutions can be provided for moving the latching element into the unlocking position:

1. The mechanical movement of the latching element into the unlocking position, preferably pressing it out of the counter lock, is effected mechanically by means of the counter lock, in particular by means of a latching element actuation part which is moved by means of an actuation part.

2. The mechanical lock is used to move the latch element from the locked position back to the unlocked position by means of the lock actuator element, in particular by means of the lock driver. The lock actuating element can be designed as a toggle lever. In this case, the lock actuation element can be connectable to the handle and/or the panic lever. In addition or alternatively, the lock actuating element can be designed as a lock cylinder. The lock actuation element can interact with the bolt element via a lock mechanical element, in particular via a lock slide.

3. Electromechanically, in that the locking element is moved into the unlocking position by the lock actuator.

According to one advantage, it can be provided that the counter lock actuator is deactivated as soon as the work performed by the counter lock actuator exceeds a limit value, wherein in particular the counter lock actuator is subsequently reactivated at least once, preferably several times, in order to continue the movement of the first locking lever. A safe shut-off can thus be provided for improved reliability. The secure shut-off can help to increase the service life of the paired lock actuator. In particular, the limit value can be detected for this purpose by means of overcurrent detection, for example by means of an electronic current sensor, such as a shunt resistor or the like.

In particular, during unlocking of the lock device, the lock actuator is activated before the counter lock actuator is activated. This ensures that the latching element actuation part remains spaced apart from the latching element, so that no work has to be done on the lock actuator to move the latching element. This makes it possible in particular for the latch element to be moved by the lock actuator into the unlocking position without the counter lock actuator. If the lock actuator is activated before the lock actuator is mated, it can be ensured in particular that the latching element remains spaced apart from the latching element actuation part, while the latching element is moved electromechanically by the lock actuator into the unlocking position. This has the advantage that the mechanical loading by pressing the latching element out through the latching element actuation part is only necessary when electromechanical actuation has to be dispensed with and/or the latching element has to be moved mechanically from the side of the counter lock into the unlocking position, for example in the event of an emergency opening at the counter lock.

Preferably, during locking of the lock device, the counter lock actuator is activated before the lock actuator is activated. This ensures that the latch element actuation part does not block the opening of the counter lock.

Preferably, during locking of the lock device, the counterpart lock actuator and the lock actuator are activated such that the latch element remains spaced apart from the latch element manipulation when moved into the locking position.

Preferably, during unlocking of the lock device, the control device first causes the lock actuator to move the latch member to the unlocking position. The first and/or second latch lever connection is moved into the insertion position by the counter lock actuator, in particular by the control device, only when the latch element is in the unlocking position. Alternatively, a counterpart lock actuator is activated during the unlocking of the lock device, and the lock actuator moves the latching element to the unlocking position.

Preferably, during the locking process, the counter lock actuator, in particular by the control device, first causes the movement of the bolt bar joint into the removal position. The lock actuator, in particular via the control device, causes the movement of the latch element into the locking position only when the latch rod connection is in the removal position. Alternatively, the lock actuator is activated during locking of the lock device, and the counterpart lock actuator causes the movement of the latching lever joint to the removal location.

It is conceivable that the lock device comprises at least one monitoring mechanism, wherein the monitoring mechanism detects the position of the latching element, of at least one latching lever joint or of a latching element manipulation. The monitoring device can be designed as a switch or as a sensor. The monitoring signal of the monitoring device can be used to activate and/or deactivate the lock actuator and/or the counter lock actuator. The monitoring signal is used in particular to activate and/or deactivate the lock actuator and/or the counter lock actuator during an unlocking process of the lock device and/or during a locking process of the lock device.

If the monitoring mechanism monitors the position of the latching element, the monitoring mechanism is preferably located in the lock housing. If the monitoring mechanism monitors the position of the latching element operator or the first and/or second latching rod joint, the monitoring mechanism is preferably located in the mating lock housing.

The control device is preferably able to receive a monitoring signal of the monitoring device and to actuate the lock actuator and/or the counter lock actuator after evaluation of the monitoring signal. For this purpose, the control device and the monitoring means can be electrically connected or wirelessly communicated.

The monitoring mechanism does not have to directly detect the position of the latching member, the latching rod joint or the latching member operator. Rather, it is sufficient to detect the position of an element coupled to the latching element, the latching lever joint or the latching element actuation, for example a lock mechanical element or a counter lock mechanical element. Thus, detecting the position of the latching member, of the latching rod joint or of the latching member manipulation member by the monitoring means comprises indirect detection.

Preferably, at least one monitoring signal of the monitoring mechanism is used to detect the position of the latching element during unlocking of the lock device. It is particularly preferred that the unlocking point is detected as the position of the latching element to be detected.

Preferably, at least one monitoring signal of the monitoring means is used to detect the position of the latching element operator or of the first or second latching lever contact during the locking of the lock device. Preferably, as the position to be detected, the retracted position of the latch member operating member or the removed position of the first or second latch rod joint is detected.

The lock can in particular be a self-locking lock. In this case, the latching element can be automatically moved mechanically into the locking position when the lock is in opposition to the counter lock. For this purpose, the lock can comprise, in particular, a control bolt. The lock can be designed in particular as an emergency lock (Anti-Panik Schloss). In this case, the latching element can be mechanically movable into the unlocking position by actuating the panic lever or the door handle. The lock can include a toggle member that can be connected to the panic lever and/or the door handle.

In the unlocked position, the lock actuator prevents self-locking of the lock.

Preferably, it is provided that, when a permanent unlocking command for permanent unlocking of the locking device is issued to the locking device, this command holds a counter lock actuator connected to the counter lock actuator in an unlocking position in which the latching lever connection is in the retracted position. The permanent unlocking command is received in particular by the control device. In particular, when a permanent unlocking command for permanent unlocking of the locking device is issued to the locking device, a lock actuator connected to the lock actuator is held in an unlocking position in which the latching element is in the unlocking position.

In addition to the unlocking and locking process of the lock device and the permanent unlocking of the lock device, an electromechanical unlocking process, a locking process and/or a permanent unlocking of the lock is possible. For this purpose, only the lock actuator is required. The counter lock actuator remains non-intrusive. The fixed fan remains locked.

The subject of the invention is also a locking system with a lock device comprising a lock for a movable leaf door and a counterpart lock for a fixed leaf door. The lock comprises at least one latch member. The latching element engages in the opening of the counter lock in a locking region of the latching element. Furthermore, the counterpart lock comprises at least one, in particular first, latch rod connection for connection with the first latch rod. The mating lock includes an electromechanical mating lock actuator for moving the first latch rod. In this case, it is proposed that the lock comprises an electromechanical lock actuator for moving the latching element. The locking system comprises an, in particular, electromechanical control device, wherein the control device activates a counter lock actuator in order to move the latch lever, such that the lock actuator at least partially causes and/or at least partially takes over the movement of the latch element.

The locking system according to the invention therefore also brings about the advantages as have been described in detail in connection with the method according to the invention. Furthermore, the locking system according to the invention is suitable for being described in terms of the method according to the invention. Causing movement of the latching member includes activating movement of the latching member and allowing movement by the lock actuator. Activating the pair of lock actuators to move the latchbolt includes activating movement of the latchbolt by the pair of lock actuators and allowing movement of the latchbolt by the pair of lock actuators.

According to an advantageous further development of the invention, it can be provided that the counter lock comprises a counter lock housing and the counter lock actuator is arranged in the counter lock housing. In particular, a latch element actuator can be provided in the counter lock housing for moving the latch element into an unlocking position and/or an actuating element, for example a toggle or a lock cylinder, for mechanically moving the first latch lever into the retracted position and/or for moving the latch element actuator. This has the following advantages: in addition to electromechanical actuation, purely mechanical actuation via the actuating element is also possible.

By providing the counter lock actuator in the same counter lock housing as the locking pin element manipulation, the counter lock can be constructed particularly simply and compactly. In addition or as an alternative to the counter lock actuator being arranged in the counter lock housing together with the latch element manipulation, the counter lock actuator can be arranged in the counter lock housing together with the first and/or second latch rod joint and/or the counter lock mechanical element. Particularly preferably, the counter lock actuator is arranged within the counter lock housing together with the latch element actuating element and the at least one actuating element. The counter lock housing can comprise at least one-piece counter lock housing bottom.

According to a further advantage, it can be provided that the counter lock actuator is arranged in a counter lock housing, wherein the counter lock housing has a length of no more than 13.5cm and/or a height H of no more than 17cm, and/or the counter lock is designed as a built-in lock. The width can be predetermined and/or adapted to the width of the fixed leaf door. Advantageously, the counter lock actuator can be arranged in a counter lock constructed according to DIN 18251-1: 2002-07. The counter lock, in which the counter lock actuator is integrated, can be insertable into a lock recess which is designed in accordance with DIN 18251-1:2002-07 for the built-in lock. This enables a reliable and standard-compliant use of different fixed leaf doors.

According to a further possibility, it can be provided that the counter lock comprises a counter lock mechanical element for moving the first lock bolt lever. The latching lever can in particular be movable from the extended position into the extended position by means of a counter lock mechanism element. The counter-locking mechanical element preferably moves the first locking bar connection, particularly preferably from the removal position into the insertion position. Preferably, the latching element actuation part is moved in particular from the retracted position into the active position by means of a counter-locking mechanical element.

Thus, the counter lock mechanical element has multiple functions. Thus, the counter lock mechanical element can be used multiple times for unlocking: on the one hand, the latching element is moved into the unlocking position by means of a counter-locking mechanical element; on the other hand, the first latch lever is moved to the moved-in position by means of the mating lock mechanical element. Particularly preferably, the second latching lever is also moved into the retracted position by means of a counter-lock mechanical element.

The counter lock mechanical element can be formed in particular in one piece.

The counter lock mechanical element can be configured as a slider. The slide can be mounted on the counter lock housing in a translatory manner. A low-cost and reliable mechanical structure for carrying out the unlocking can thus be provided.

Within the scope of the invention, it can be provided that the first and/or the second latching lever connection can be moved by means of the actuating element via a counter lock mechanical element, wherein the latching lever connection can be moved by means of a counter lock actuator via the counter lock mechanical element. The first and/or second latch lever can thus be mechanically and electromechanically unlocked by the same counter-lock mechanical element.

The actuation of the actuating element can mechanically override the movement of the counter lock actuator. Preferably, the counter lock mechanical element is brought out of operative connection with the counter lock actuator by actuating the actuating element. In particular, mechanical retraction of the first and/or second latch rods does not adversely affect the mating lock actuator.

Additionally or alternatively, the movement of the counter lock actuator can mechanically override the actuation of the actuating element. Upon actuation of the counter lock actuator, the counter lock mechanical element can be brought out of operative connection with the actuating element. Thus, mechanical actuation can be reliably provided in addition to electromechanical actuation. If the first and/or second latch rod is electromechanically retracted, then: the actuating element must be moved by the counter lock actuator. Thus, the mating lock actuator requires less electrical power.

In addition, it can be provided within the scope of the invention that the lock actuator is of identical design to the counter lock actuator. This makes it possible to achieve significant cost savings and/or to ensure a uniform and synchronized movement sequence when unlocking the lock and, in the case of a counterpart lock.

It can also be provided that the lock actuator acts on the latch element via a lock transmission and the counter lock actuator acts on the latch lever connection via a counter lock transmission, wherein the lock transmission and the counter lock transmission each comprise a cam. The cam of the lock gear can be arranged on a wheel, in particular a toothed wheel, of the lock gear. The cam of the counter lock gear can be arranged on a wheel, in particular a toothed wheel, of the counter lock gear. It is possible that the cam of the counter lock transmission is used to act on the counter lock mechanical element to move, in particular to move, the counter lock mechanical element. It can be provided that the cam of the counter lock gearing can be disengaged from the counter lock mechanical element. The counter lock actuator releases the movement of the counter lock actuator if the cam of the counter lock actuator is in disengagement with the counter lock mechanical element. In the unlocked position of the counter lock actuator, the cam is in engagement with the counter lock actuator.

It is possible that the counter lock mechanical element comprises a projection, on which the counter lock gearing, in particular a cam, can act. In particular, the counter lock mechanical element, in particular the projection, can be shaped such that the counter lock gear, in particular the cam, can act on the counter lock mechanical element, in particular the projection, only from one direction, in particular from the direction of rotation. In addition or alternatively, the counter-lock mechanical element, in particular the projection, can be shaped such that the counter-lock mechanical element can always be moved by means of the toggle piece. Thus, the counter lock mechanical element, in particular the projection, can be shaped such that the following movements are prevented: by means of this movement, it is possible to reach a position in which the cam blocks the movement path of the counter-lock mechanism. In particular, the cam can be at least partially prevented from moving opposite to the usual direction of rotation.

The lock actuator can include a cam engageable with the lock mechanical element. In the unlocking position of the lock gear, the cam is in engagement with the lock mechanism, in particular with a projection of the lock mechanism.

Furthermore, it is conceivable within the scope of the invention for the counter lock to comprise an energy accumulator, wherein the energy accumulator is used to disengage the counter lock actuator from the counter lock mechanical element when or after the counter lock actuator moves the first lock bar into the moved-in position. The energy accumulator can be used to move the counter lock gearing into the release position. It is thus possible to provide a state in which it is possible to maintain mechanical and electromechanical manipulations. In particular, a state is provided in which self-locking of the counter lock is possible. The energy store can comprise at least one capacitor or accumulator. Additionally or alternatively, the energy accumulator can be arranged in the counter lock housing. The energy accumulator can be used in particular as a backup power source. The energy accumulator is thus used to move the counter lock transmission from the unlocking position into the release position and/or to move the counter lock actuator out of the operative connection with the counter lock mechanical element in the event of a power failure.

If the control device is informed of a sudden fire, the control device can cause the transmission to move into the release position and/or move the counter lock actuator out of operative connection with the counter lock mechanical element. If the control device is aware of a sudden fire, the control device can cause the counter lock actuator not to move to the unlocked position. The control device can be connectable, for example, at least indirectly to a fire alarm in order to be informed of a fire.

It can furthermore be provided that the locking system comprises an in particular electronic control device, wherein the control device actuates, in particular activates, the lock actuator and the counter lock actuator, wherein the control device is arranged in the lock device, in particular in a lock housing of the lock and/or in a counter lock housing of the counter lock, wherein in particular the first control unit is arranged in the lock housing and the second control unit is arranged in the counter lock housing. The control device, i.e. also the corresponding control unit, can comprise, for example, at least one microcontroller or processor or the like in order to carry out the activation. In particular, the control unit can comprise a first and a second communication means in order to communicate with each other. For example, the control units can be electrically connected to each other, for example in order to exchange data. Preferably, the locking system according to the invention can comprise or correspond to a locking device.

A further advantage according to the invention is achieved in that the locking system comprises a control device, wherein the control device actuates, in particular activates, the lock actuator and the counter lock actuator, wherein the locking system comprises a, in particular, electrically operated door drive, wherein preferably after the movement of the latch element into the unlocking position and the movement of the first latch lever into the retracted position the control device activates the door drive in order to open the movable leaf door and the fixed leaf door. In particular, the control device can be provided in the door drive. Preferably, the door drive is formed and/or arranged outside the lock and the counter lock, for example adjacent to the door leaf, in order to safely and reliably carry out the control of the door.

Detailed Description

In fig. 1, a front view schematically shows a counterpart lock 100 of a locking system 400 according to the invention. Fig. 2 to 5 show the counter lock 100 in further perspective views. Preferably, such a counterpart lock 100 can be used for a fixed leaf door, wherein the lock 1 of the movable leaf is arranged adjacent to the counterpart lock 100. Such a lock 1 of the corresponding device is thus shown in fig. 1, for example, with a dashed line. Lock 1 and mating lock 100 together form a lock device 700 (see fig. 8).

It can be seen that in the position of the latch element 20 of the lock 1, an opening 110 for the latch element 20 can be formed in the counter lock housing 170. The latching elements 20 are designed as latches. Likewise, in the position of the second latch element 70, such as the deadbolt 70, there can be a corresponding opening 220, in particular the deadbolt opening 220, in the counter lock case 170. Thus, the lock 1 and the counterpart lock 100 cooperate for locking.

The lock 1 is configured as a self-locking lock 1. In this case, the movement of the latch element 20 from the unlocking position into the locking position is caused each time the sliding door is closed. In the unlocked position, the latch member 20 is outside the opening 110. In the locking position, the latch element 20 is located in the opening 110.

In addition to the latching elements 20, at least one latching lever 520 is provided as a mechanism for locking, i.e. for example a first latching lever 521 and a second latching lever 522 (see fig. 1). These latching levers are in particular connected immovably and fixedly to the associated latching lever connections 120 of the counterpart lock 100. The latch rod joint 120 is movably received in the mating lock housing 170 to move the latch rod 520. In particular, the first latch rod joint 121 is provided for the first latch rod 521, while the second latch rod joint 122 is provided for the second latch rod 522. In this case, the corresponding latch lever connection 120 can be moved from the removal position into the insertion position by means of the slider 160 of the counter lock 100. The latch rods 520 connected to the respective latch rod joints 120 are able to move out of the removal location and into the mating lock housing 170 in the removal location. In the removal position, the locking can be achieved, for example, by the latch rod 520 being inserted into a receptacle in the door frame, wall, ceiling or floor. Therefore, in order to unlock, i.e. move into the moved-in position, the latch rod joint 120 must be moved into the moved-in position.

The lock device 700 is particularly suitable here for escape doors, fire doors, etc. The device 700 can be mechanically unlockable by means of the lock 1 and the counter lock 100 for at least one door leaf.

The lock 1 comprises a lock operating element 32, such as a toggle member. By actuating the lock actuating element 32, for example by means of a panic lever or a door handle, the latch element 20 can be moved from the locking position into the unlocking position. In this case, the lock actuating element 32 and the bolt element 20 are operatively connected to one another via a lock slide 33 as a lock mechanical element. When the lock actuation element 32 is actuated, the lock slide 33 is moved.

The latch tongue 70 is configured as a cross latch tongue. When the latch member 20 is in the locked position, the latch tongue 70 is locked. By actuating the lock actuating element 32 and thus the lock slider 33, the locking tongue is unlocked, so that the locking tongue 70 can be retracted into the lock housing 10 when the movable door leaf is opened. Thus, by actuating the lock actuating element 32, for example by means of a panic lever or a door handle, the lock 1 can be unlocked, so that the sliding leaf door can be opened. The fixed leaf door remains locked due to the latch lever 520 being in the removed position.

By actuating the actuating element 141, in particular a toggle lever, via a panic lever or a door handle, a mechanical interaction of the counter lock 100 with the lock 1 is triggered for unlocking. The latch member operator 130 of the mating lock 100 is positioned adjacent the opening 110 to force the latch member 20 out of the mating lock housing 170. By moving the bolt element 20 into the unlocking position, the locking tongue 70 is simultaneously unlocked by the movement of the lock slider 33, so that the locking between the lock 1 and the counter lock 100 is released by actuating the actuating element 141. At the same time, the latch rod connection 120 is moved from the removal position into the insertion position by actuating the actuating element 141. Thereby, the movable fan and the stationary fan are unlocked. Thus, it is possible to mechanically actuate the actuating element 141 in such a way that the movable door and the fixed door are openable in an emergency situation.

According to the invention, in addition to the mechanical emergency unlocking, an electromechanical unlocking is also proposed. In the case of an electromechanical lock, the movable leaf door and the fixed leaf door are unlocked so that the movable leaf door and the fixed leaf door are openable. In this case, the lock device 700 is transferred from the locked state to the unlocked state. To this end, in accordance with the present invention, the counterpart lock 100 includes a counterpart lock actuator 142, and the lock 1 includes a lock actuator 30 (see fig. 9). The counter lock actuator 142 is designed as an electric motor. The lock actuator 30 is designed as an electric motor. In accordance with the present invention, lock actuator 30 and mating lock actuator 142 cooperate. Unlike in the case of mechanical unlocking via the counterpart lock 100, where the latch element 20 and the latch rod 520 are moved by manipulation of the manipulation element 141, the counterpart lock actuator 142 does not cause movement of the latch element 20 and the latch rod 520 separately. Instead, the counterpart lock actuator 142 is assisted by the lock actuator 30, so that the lock actuator 30 at least partially assumes the movement of the latch element 20 from the locking position to the unlocking position. Thereby, a quick, simple and/or safe unlocking of the movable leaf door and the stationary leaf door is possible. For this purpose, a control device 510 (see fig. 8) is provided. The control device 510 coordinates the activation of the lock actuator 30 and the mating lock actuator 142.

Activation of lock actuator 30 and counter lock actuator 142 is performed such that first lock actuator 30 moves latch element 20 from the locking position to the unlocking position and then counter lock actuator 142 moves latch rod 520 from the removed position into the removed position.

The counter lock mechanical element 160 is configured as a slider 160. The slider 160 is operatively connected to the latch member operator 130 and the first and second rod joints 120. If the first and second latch rods 520 should move from the extended position into the extended position, the latch member operators 130 are always moved in addition to the first and second latch rod joints 120.

The control device 510 preferably activates the lock actuator 30 before the lock actuator 142 is mated in order to carry out the unlocking process of the lock device 400. It can thus be safely provided that the counter lock actuator 142 does not have to perform an electrical function in order to move the latch element 20. Instead, lock actuator 30 alone undertakes movement of latching member 20 from the locking position to the unlocking position. Thus, during an electro-mechanical lock, the latch member handler 130 and the latch member 20 remain spaced apart from each other.

The counter lock actuator 142 is additionally protected against excessive loads by: it is measured whether the work performed by the pairing lock actuator 142 exceeds a limit value. If the limit value is exceeded, the pairing lock actuator 142 is deactivated. Thus, lock actuator 30 is provided with the possibility of moving latch member 20 for a short time, while counter lock actuator 142 does not do work. If the latch element actuation member 130 should still abut against the latch element 20, in particular the counter lock actuator 142 should take part in the movement of the latch element 20, the latch element actuation member 130 can be spaced apart from the latch element 20 by a short end of the actuation of the counter lock actuator 142. Thus, when the pair lock actuator 142 is reactivated, the workload for the pair lock actuator 142 is reduced. The reactivation of the pairing lock actuator 142 is effected by the control device 510.

The counter lock actuator 142 is disposed in the counter lock housing 170 along with the latch member operating member 130 and the operating member 141. In particular, the counter lock housing has a length L not exceeding 13.5cm and a height H not exceeding 17cm (see fig. 4) and is therefore suitable for being arranged in a standardized recess of a fixed leaf door.

The lock actuator 30 is arranged in the lock housing 10 together with the lock actuating element 32 and the lock slider 33. The lock housing is also adapted to be disposed within a standard recess of a door leaf.

Lock actuator 30 and mating lock actuator 142 are implemented identically to one another in construction.

The movement of the sliding block 160 is embodied in fig. 1 as a movement guided in translation in a counter lock housing 170. The slider 160 is movable from a first position in which the at least one latch bar joint 120 is in the displaced position to a second position in which the at least one latch bar joint 120 is in the displaced position. In this case, the counter lock 100 can have at least one counter lock spring 180, which presses the slider 160 into the first position. A mating lock spring 180 acts on at least one of the latch rod joints 120.

The movement of the latch rod joint 120 can be brought about by actuating the actuating device 140, i.e. for example by actuating the actuating element 141 and/or by electromechanical mating lock actuators 142. The actuating element 141 is designed as a toggle element 141 and acts on the slider 160 during rotation. The pairing lock actuator 142 acts on the slider 160 via the pairing lock actuator 200. In this case, the mating lock actuator 142 can be in operative connection and out of operative connection with the slider 160. For example, it is shown that the counter lock actuator 200 comprises a cam 201, wherein the counter lock actuator 200 abuts against the slide 160 by means of the cam 201 when the counter lock actuator 142 is in operative connection with the slide 160. To this end, the slider 160 can include a first protrusion 191 with which the cam 201 comes into contact. If the cam 201 abuts the protrusion 191 and holds the slider 160 in the second position, the counter lock actuator 200 is in the unlocked position. When cam 201 is not abutting first projection 191, mating lock actuator 142 is disengaged from operative connection with slider 160. Thus, the mating lock actuator 200 is in the release position. When the slider 160 is moved from the first position to the second position by actuating the actuating element 141, the slider 160 and the counter lock actuator 142 are disengaged from each other. In this case, the slider 160 moves away from the cam 201. Thus, mechanical unlocking is possible by means of the actuating element 141, without the counter lock actuator 142 blocking the mechanical unlocking and/or the counter lock actuator 142 not being damaged in the case of mechanical unlocking.

If the cam 201 of the counter lock actuator 200 is in operative connection with the slider 160 and the slider 160 is in the first position in this case, the counter lock actuator 200 is in the unlocked position. In the unlocked position, movement of the slider 160 is blocked by the mating lock spring 180. Self-locking of the counter lock 100 is undone. If the counter lock actuator remains in the unlocked position, there is a permanent locking of the counter lock 100.

In order to actuate the counter lock actuator 200, in particular in order to disengage the counter lock actuator 142 from the slider 160 and/or to move the counter lock actuator 200 from the unlocked position into the release position, the counter lock 100 can have an energy accumulator 105 (as schematically illustrated in fig. 8). Accumulator 105 stores sufficient energy to activate mating lock actuator 142 long enough that cam 201 no longer abuts first protrusion 191. Thus, the mechanical movement of the slider 106 is not blocked by the cam 201. The accumulator 105 serves as a backup power source to reliably provide mechanical self-locking of the lock 100 in case of fire.

Furthermore, it is conceivable for the actuating element 141 to bear against the slider 160, in particular against the second projection 192 of the slider 160. In this case, the actuating element 141 can be disengaged from the operative connection with the slider 160 by actuating the counter lock actuator 142. In this case, the second projection 192 of the slider is moved away from the actuating element 141 by the movement of the slider. Thus, the actuating elements 141 do not have to be moved together when the slide 160 is moved from the first position to the second position by the counter lock actuator 142.

Fig. 4A shows a modified form of the slider 160. In this case, the first projection 191 has a projection 196. The protrusion 196 prevents the cam 201 from being able to sit over the first protrusion 191 during counterclockwise movement and thereby block movement of the slider 160 from the first location to the second location. The projection 196 allows only clockwise movement of the cam 201 to effectively couple with the first protrusion 191. Therefore, the movement of the slider 160 from the first position to the second position is always ensured by the projecting portion 196.

The lock gear 31 and the counter lock gear 200 can comprise identically constructed components (see fig. 9).

As already explained, in order to move at least one of the latch rods 520, the counter lock actuator 142 can be activated such that the lock actuator 30 at least partially moves the latch member 20. In other words, the actuators of the locking system 400 can be actuated in conjunction with one another. For this purpose, for example, the control device 510 illustrated in fig. 8 can be used, which is integrated, for example, in the motorized door drive 410 outside the lock device 700 (not shown). The locking system 400 according to the present invention can include a powered door driver 410. The motorized door drive 410 is used to electrically open the movable leaf door and, if necessary, the stationary leaf door after the movable leaf door is unlocked and, if necessary, the stationary leaf door is unlocked.

Alternatively, the control means 510 can be provided within the lock arrangement 700. For example, the control means 510 can comprise a first control unit 511 in the lock 1 and a second control unit 512 in the counterpart lock 100. In particular, control device 510 is electrically connected to lock actuator 30 and/or counter-lock actuator 142 in order to activate the actuators. In this case, it is possible that the locking system according to the invention does not comprise a door drive 410.

As further shown in fig. 2 and 3, it can be possible for at least one of the latch lever connections 120 to be connected with play to the slide 160 and preferably to rest on a third projection 193 of the slide 160. This facilitates, for example, operational protection during an active movement of the latch rod connection 120 into the interior of the counter lock housing 170, which is introduced from the outside via the latch rod 520. In this case, then, the latch rod interface 120 is first placed on the blocking surface of the latch member manipulating member 130 before movement may be transmitted to the slider 160. The connection between the latch rod joint 120 and the slide 160 can also be embodied such that the slide 160 first moves the latch element actuation part 130 and only then the latch rod joint 120.

As can be seen in fig. 1 and 7, at least the upper of the latch bar joints 120 can be connected with a slider 160 via a lever 150. Such a lever 150 can transmit the movement of the slider 160 to the further latching lever connection 120 in a manner supported on the pivot point 152. In particular, in this way, the movement of the plurality of latch rod connections 120 via the single slider 160 can be reliably achieved via the lever 150 on the one hand and the third projection 193 on the other hand.

The slider 160 can be guided, in particular positively, at least twice on the counter lock housing 170. For the guidance, the slider 160 can have at least one elongated hole 194, wherein the pivot point 152 of the lever 150 can simultaneously serve as a guide element for the slider 160.

It is also possible that the slider 160 directly contacts and/or abuts the latch member operator 130 and/or at least one of the latch rod joints 120.

By means of the slider 160, the latch element manipulation member 130 is movable in the manner of: the latch member operating member 130 is forcibly guided by the slider 160 through the slide groove 195.

Fig. 1 also shows a plurality of through holes 173, into which a through screw connection for fastening a standard fitting can be introduced. For this purpose, the through-hole 173 is provided such that it complies with the specifications of a standard fitting. In particular, the threaded through-connection can also serve here to guide the slider 160, so that there is (at least) a dual functionality of the through-hole.

The latching element manipulator 130 can also have one or more functions, such as movement of the latching element 20 of an adjacent lock 1 of the lock device 700 for unlocking, and/or operational protection of the counterpart lock 100 and/or of the lock device 700. As shown in fig. 8 according to the lock device 700 of the locking system 400, the latch element 20 can engage into the opening 110 of the counter lock 100 in the locking region of the latch element 20. In addition to this, the lock 1 can comprise at least one control tongue 50, wherein the control tongue 50 assumes a retracted position in order to move the bolt elements 20 into the locking position. In contrast, in the extended position, the control tongue 50 mechanically prevents the latch member 20 from moving to the locked position. To maintain the control bolt 50 in the retracted position, a flapper 210 can be provided that mates with the lock 100 such that closing the door causes movement of the control bolt 50 in and is retained by the flapper 210. The latch member operator 130 of the counterpart lock 100 is movable from the retracted position to the active position. This is done in particular when the actuating device 140 is actuated, so that the latch element actuating element 130 can increase the reliability of the opening process of the door. In the active position, the latch element actuation part 130 is designed to hold the latch element 20 in the unlocking position until the locking bolt 50 is moved away from the catch 210 and reaches the extended position. In other words, it is possible to prevent: when the door is opened, i.e. when the stationary and/or movable leaf is moved, the latch element 20 is moved back into the locking position. Furthermore, the latch element actuation member 130 can press the latch element 20 out of the counter lock housing 170 by means of the active element 131 of the latch actuation member by means of a movement from the retracted position into the active position. Both can be caused mechanically by the connection of the latch element actuation member 130 to the slider 160 in the following manner: the slider 160 mechanically acts on the actuating member 132 of the latch member operator 130.

Further details of the lock 1, which is also a component of the locking system 400, are shown in fig. 9 and 10. In this case, it can be seen that the lock 1 can have a lock housing 10 in which a lock slide 33 is movably guided. In addition, the lock actuator 30 is provided with a lock gear 31 in order to move, in particular, a lock slide 33. Furthermore, the movement of the lock slide can cause the locking tongue 70, which has a locking tongue head 71 for locking, to be unlocked. The lock slide 33 can be used for movement and/or guidance of the bolt element 20, which can be influenced by the state of the bolt 70 and the control bolt 50. Thus, the latch member 20 can be, for example, turned into the locked position only when the deadbolt 70 is turned into the unlocked position and the deadbolt 50 is controlled to be turned into the retracted position. For this purpose, the catch element 80 can be changed from a locking position to a release position, wherein the catch element 80 can be moved independently of the position of the locking bolt 70 by controlling the movement of the locking bolt 50.

Furthermore, it is possible that the lock 1 according to fig. 8 comprises a bolt element sensor 650 as a first monitoring mechanism and that an alarm is generated when the control bolt sensor 600 shown in fig. 9 as a second monitoring mechanism detects that the control bolt 50 is in the extended position and at the same time the bolt element sensor 650 detects that the bolt element 20 is in the locking position.

The cam 34 of the lock gear 31 shown in fig. 9 and 10 can act on the projection 35 of the lock slide 33 in the unlocking position and hold the latch element 20 in the unlocking position via the lock slide 33. This results in permanent unlocking of the lock 1.

Additional details of the latch member operator 130 are shown in fig. 2, 3 and 7. In the active position, the latch element actuation part 130 rests, for example, elastically against the latch element 20 and for this purpose is formed in multiple parts as an active element 132 and an active element 131. In this case, the movement of the actuating element 141 of the counter lock 100 can move the actuating element 132, so that the active element 131 abuts against the latch element 20 in the active position by means of the end face 134 of the active element 131. In addition, the latch member manipulation member 130 includes a blocking surface 133 that blocks movement of at least one of the latch rod joints 120 into the second position in the retracted position. The corresponding latch rod 520 can be prevented from being retracted without permission. In addition, the latch element handler 130 can include a bearing surface 136 for guiding the slider 160. Advantageously, the active element 132 and the active element 131 are elastically connected to each other. For this purpose, the spring 135 of the latching element actuation part 130 can be designed as a helical spring. As a further embodiment variant of the latching element actuation member 130, the reaction element 132 can be pivoted about a first axis, wherein the active element 131 is mounted on the reaction element 132 so as to be pivotable about a second axis, and the spring 135 is embodied as a leaf spring (see fig. 6).

The pairing lock 100 of fig. 6 can also include a pairing lock actuator, not shown. The counter lock actuator 100 can be located in its own housing in the embodiment of fig. 6, which is connected to the counter lock housing 170. The counter lock actuator 100 is also capable of acting on the counter lock mechanical elements of the counter lock of fig. 6. In this case, movement of the toggle member can override movement of the paired lock actuator in the same manner as described in the embodiment of fig. 1 to 5. Movement of the mating lock actuator can also override manipulation of the toggle member in the same manner as described in the embodiment of fig. 1 to 5.

To this end, the second door driver 420, which is electrically operated, includes a second motor 481. The second door driver 420, which is electrically operated, includes an electronic device 431 for controlling the second motor 481.

The lock 1 comprises a first control unit 511. The first control unit 511 is arranged in the lock housing 10 of the lock 1. The first control unit 511 is designed as a microcontroller. The first control unit 511 includes a processor and a nonvolatile memory.

The counter lock 100 comprises a second control unit 512. The second control unit 512 is arranged in the counter lock housing 170 of the counter lock 100. The second control unit 512 is designed as a microcontroller. The second control unit 512 includes a processor and a nonvolatile memory.

The first control unit 511 comprises a first communication means 513 and the second control unit 512 comprises a second communication means 514. The first and

second control units

511, 512 communicate with each other by means of first and second communication means 513, 514. In this case, the first and second communication means 513, 514 are designed as electrical connections. The first and

second communication mechanisms

513, 514 are connected to each other via an electrical connection 560. The first and

second control units

511, 512 are capable of exchanging data bi-directionally via electrical connection 560. The electrical connection 560 can be designed as a bus, for example as an RS485 bus. Preferably, the bus users are limited to the first and

second control units

511, 512.

For the sake of overview, the electrical connections within the lock housing 10, the counter lock housing 170 and the electric drives 410, 420 are not shown in fig. 11. It is apparent that the electrical connection 560 passes from the first communication mechanism 513 to the second communication mechanism 514. The lock 1 has an interface device 540 designed as a plug connector. The counter lock 100 has an interface device 550 designed as a plug connector. The electrical connection 560 leads from the first control unit 511 to the second control unit 512 via the

interface device

540, 550.

Lock 1 may be connected to a bus system 530. Via the bus system 530, the first control unit 511 is able to receive and/or transmit data. The first control unit 511 is able to communicate with at least one further device via the bus system 530. The further device can be, for example, at least one of the

electronic devices

430, 431. The first control unit 511 is a subscriber of the bus system 530. The second control unit 512 is not able to communicate directly with the bus system 530. Instead, data, e.g. instructions, which may relate to the second control unit 512 are first received by the first control unit 511. The first control unit 511 then forwards or generates instructions for the second control unit 512 accordingly.

The lock 1 includes a plurality of

monitoring mechanisms

600, 650, 651, 652, 653. The

monitoring devices

600, 650, 651, 652, 653 can be designed as switches or sensors. The monitoring means 600, 650, 651, 652, 653 are electrically connected to the first control unit 511. The first control unit is capable of receiving an electrical signal monitoring the

means

600, 650, 651, 652, 653.

Purely by way of example, the following monitoring means are provided in the lock 1: the first monitoring means 653 is used to monitor the lock gear 31. The second monitoring mechanism 652 is configured to monitor the toggle 32. The third monitoring mechanism 651 is used to monitor whether the lock 1 is in the unlocked state, and in particular whether the latching members 20 are in the unlocked position. The fourth monitoring means 650 is used to monitor whether the lock 1 is in a locked state, in particular whether the bolt element 20 is in a locked position. In this case, the third and

fourth monitoring mechanisms

651, 650 can monitor the position of the latch member 20, as depicted in fig. 11. In an alternative embodiment, the

monitoring mechanism

650, 651 can monitor the position of the lock mechanism member 33 coupled to the latching member 20. The fifth monitoring mechanism 600 is used to monitor the movement of the control tongue 50. The first control unit 511 is able to control the lock actuator 180 using at least a part of the

monitoring mechanism

600, 650, 651, 652, 653.

The counter lock 100 includes a plurality of monitoring mechanisms 654, 655, 656, 657. The monitoring means 654, 655, 656, 657 are arranged in the counter lock housing 170. The monitoring means 654, 655, 656, 657 can be designed as switches or sensors. The monitoring mechanisms 654, 655, 656, 657 are electrically connected to the second control unit 512. The second control unit 512 is capable of receiving electrical signals of the monitoring means 654, 655, 656, 657.

The first monitoring device 657 is used to monitor the pairing lock transmission 200. The second monitoring mechanism 656 is used for monitoring the toggle member 141. The third monitoring mechanism 655 is used for monitoring whether the pairing lock 200 is in an unlocked state. The fourth monitoring mechanism 654 is used for monitoring whether the pairing lock 200 is in a locked state. In this case, the third and fourth monitoring mechanisms 654, 655 can monitor the position of the first and/or second latch bar joints 120. In an alternative embodiment, as depicted in fig. 1, the monitoring mechanisms 654, 655 are capable of monitoring the position of the mating lock mechanism element 160 coupled with the latching bar joint 120. In another alternative embodiment, the monitoring mechanisms 654, 655 can monitor the position of the latch member manipulator 130. The second control unit 512 is able to control the pairing lock actuator 142 using at least a part of the monitoring means 654, 655, 656, 657.

The first control unit 511 identifies when the holding of the lock actuator 31 and/or the counter lock actuator 200 in the unlocked position is to be ended, in particular when the permanent unlocking of the lock 1 and/or the counter lock 100 is to be ended. For this purpose, corresponding electrical signals can be present via the bus system 530 or the control lines, or the signal for permanently releasing the lock ends. The first control unit 511 issues a corresponding command to the second control unit 512 to end the permanent unlocking of the pairing lock 100. Next, the second control unit 512 activates the counter lock actuator 142 in order to move the counter lock actuator 142 from the unlocked position to the release position.

FIG. 12 shows a flow chart for an unlocking process 1400 in which lock 1 and paired lock 100 are moved to an unlocked state. In this case, a block 1401 depicted on the left side and shown with a broken line shows the manner of operation of the first control unit 511. The block 1402 depicted on the right, indicated by a dashed line, shows the way in which the second control unit 512 operates.

In a first method step 1411, the first control unit 511 receives commands via the bus system 530 or the control line: lock 1 and mating lock 100 are transferred to the unlocked state. In a second method step 1412, the first control unit 511 activates the lock actuator 30, moving the bolt element 20 via the lock mechanical element 33 to the unlocking position. In a third method step 1413, the first control unit 511 waits for reception of a monitoring signal from the monitoring facility 651 for a predetermined time interval: the latch member 20 is in the unlatched position. If the first control unit 511 receives a monitoring signal, which is indicated in fig. 12 by "+", the first control unit 511 goes to a fourth method step 1414 and sends an instruction to the second control unit 512 via the electrical connection 560: the counter lock 100 is turned to the unlocked state.

If, on the other hand, the first control unit 511 does not receive a monitoring signal within the predetermined time interval, which is denoted as "-" in fig. 12, the first control unit 511 terminates the method 1400 in this case, as a final method step 1430, the fault information is displayed optically by the display device and/or transmitted by means of the bus system 530.

If the method step 1414 is performed, the second control unit 512 receives an instruction to transfer the pairing lock 100 into the unlocked state in a fifth method step 1421. Next, in a sixth method step 1422, the second control unit 512 activates the pairing lock actuator 142. In a seventh method step 1423, the second control unit 512 waits for receiving a monitoring signal from the monitoring facility 655 for a predetermined time interval: the counter lock 100 is in the unlocked state. The predetermined time interval in method step 1423 can be different from or the same as the predetermined time interval in method step 1413. If the second control unit 512 receives a monitoring signal, which is denoted by "+" in fig. 12, the second control unit 512 goes to the eighth method step 1424 and generates as data: the counter lock 100 has been transferred to the unlocked state. Conversely, if the second control unit 512 does not receive a monitoring signal within the predetermined time interval, which is denoted by "-" in fig. 12, the second control unit 512 goes to the alternative method step 1425 and generates as data: there is a fault. In a ninth method step 1426, the second control unit 512 sends the data generated in method step 1424 or method step 1425 to the first control unit 511 via the electrical connection 560.

In a tenth method step 1415, the first control unit 511 receives data of the second control unit 512. The first control unit 511 waits for data to be received. If in method step 1415 the first control unit 511 receives fault information as data, which is indicated in fig. 12 by "-", the first control unit 511 proceeds to method step 1430 and sends the fault information via the bus system 530 and/or causes the display device to display a fault. On the other hand, if in method step 1415 the first control unit 511 receives the information: the pairing lock 100 is in the unlocked state, which is denoted by "+" in fig. 12, the first control unit 511 proceeds to method step 1416 and sends a notification via the bus system 530: lock 1 and mating lock 100 are in an unlocked state. Next, the

door drivers

410, 420 open the movable door and the fixed door.

In fig. 13, a flow chart for a locking process 1500 is shown, wherein lock 1 and the counterpart lock 100 are turned into a locked state. In this case, a block 1501 drawn on the left side and shown with a broken line shows the manner of operation of the first control unit 511. The box 1502 depicted on the right, indicated by a dashed line, shows the way in which the second control unit 512 operates.

In a first method step 1511, the first control unit 511 receives instructions via the bus system 530 or via a control line: lock 1 and mating lock 100 are turned to the locked state. The instruction can also occur as no signal: the lock 1 and the counterpart lock 100 are maintained in the unlocked state. For example, the instruction can end the persistent unlocking state. In a second method step 1512, the first control unit 511 and the second control unit 512 send instructions: the counter lock 100 is turned to the locked state.

In a third method step 1521, the second control unit 512 receives an instruction from the first control unit 511 to transfer the pairing lock 100 into the locked state. In a fourth method step 1522, the second control unit 512 activates the counter lock actuator 142 in order to move the counter lock actuator 200 from the unlocking position into the release position, so that the counter lock actuator 142 allows the counter lock 100 to be spring-loaded into the unlocking state. In a fifth method step 1523, the second control unit 512 waits for a reception of a monitoring signal from the monitoring means 654 for a predetermined time interval: the counter lock 100 is in the locked position. If the second control unit 512 receives a monitoring signal, which is indicated in fig. 13 by "+", the second control unit 512 goes to the sixth method step 1524 and generates as data: the counter lock 100 has been transferred to the locked state. Conversely, if the second control unit 512 does not receive a monitoring signal within the predetermined time interval, which is denoted by "-" in fig. 13, the second control unit 512 goes to the alternative method step 1525 and generates as data: there is a fault. In a ninth method step 1526, the second control unit 512 sends the data generated in method step 1524 or method step 1525 to the first control unit 511 via the electrical connection 560.

In a method step 1513, the first control unit 511 waits for the second control unit 512 to transmit data at predetermined time intervals. If no data reception by the second control unit 512 has occurred after the predetermined time interval, the first control unit 511 generates a fault message as a last method step 1530: the fault information is displayed optically by a display device and/or transmitted by means of the bus system 530. If method step 1526 has taken place within the predetermined time interval, the first control unit 511 receives the data and waits for data to be received in method step 1514. If in method step 1514 the first control unit 511 receives as data failure information, which is indicated in fig. 13 by "-", the first control unit 511 proceeds to method step 1430 and sends the failure information via the bus system 530 and/or causes the display device to display a failure. If, on the other hand, in method step 1514 the first control unit 511 receives the information: the counter lock 100 is in the locked state, which is indicated in fig. 13 by "+", the first control unit 511 then moves to method step 1515 and activates the lock actuator 30 in order to move the lock gear 31 out of the unlocked position, so that the lock actuator 30 allows the lock 1 to be spring-loaded into the locked state. In a method step 1516, the first control unit 511 waits for a reception of a monitoring signal from the monitoring facility 650 for a predetermined time interval: the lock 1 is in a locked state. If the first control unit 511 receives a monitoring signal, which is denoted by "+" in fig. 13, the first control unit 511 proceeds to a fourth method step 1517 and sends a notification via the bus system 530: lock 1 and mating lock 100 are in a locked state. If, on the other hand, the first control unit 511 does not receive a monitoring signal within the predetermined time interval, which is denoted by "-" in fig. 13, the first control unit 511 terminates the method 1500 with this, as a final method step 1530, displaying the fault information optically by means of a display device and/or sending the fault information by means of the bus system 530.
