Description

The present invention relates to a lock arrangement according to the type defined in more detail in the preamble of claim 1.

Doors with a stationary wing and a moving wing door are known from the prior art, in which a lock of the moving wing door is arranged adjacent to a counterlock of the stationary wing door. This enables a locking element of the lock to move into the housing of the counter lock in order to effect a locking. Furthermore, it is also known that the locking and / or unlocking is controlled by a control latch of the lock.

Such a lock arrangement is for example from the document EP 2 703 583 A2 known.

The disadvantage of the known solutions for such lock arrangements is that the control latch mechanism may not reliably enable unlocking when the door is opened. In particular, when the door is open, transferring the locking element into the locking position is problematic, since this blocks the door from being locked again. A renewed transfer to the locking position would be, for. B. possible if the control trap takes too long a retracted position during an opening process.

It is therefore an object of the present invention to at least partially remedy the disadvantages described above. In particular, it is the object of the present invention to reliably ensure that the locking element is transferred into the unlocked position when the door is opened.

The above object is achieved by a lock arrangement having the features of claim 1. Further features and details of the invention emerge from the respective subclaims, the description and the Drawings.

The object is achieved by a lock arrangement with a lock for a moving wing door and with a counter lock for a stationary wing door. The lock comprises at least one locking element, the locking element engaging in an opening of the counter-lock in a locking position of the locking element. In an unlocked position of the locking element, the locking element is preferably out of engagement with the opening of the counter-lock and / or is arranged outside of a counter-lock housing.

Furthermore, the lock comprises at least one control latch, the control latch assuming a retracted position for moving the locking element into the locking position, the movement of the locking element into the locking position being prevented in a projecting position of the control latch. The protruding position is used in particular to detect an open active leaf door, whereas the retracted position is used to detect a closed state of the door.

The counter-lock further comprises a locking element actuator, wherein the locking element actuator can be moved from a retracted position into an operative position. The counter-lock includes a strike plate to hold the control latch in the retracted position. The strike plate can thus bring about the retracted position of the control latch when the door is closed. It is provided here that the locking element actuator is designed to hold the locking element in the unlocking position in the operative position until the control latch has reached the protruding position, particularly when the door is opened. In particular, the locking element actuator in the operative position holds the locking element in the unlocking position until the control latch has reached the protruding position due to an increasing distance between the lock and the counter lock. Preferably, a control latch opening in a lock housing of the lock, through which the control latch from the retracted position into the protruding position is movable, move away from the strike plate of the counter-lock, whereby the control latch can move from the retracted position into the protruding position. While the locking element actuator holds the locking element in the operative position, the control latch can be supported on the strike plate, in particular slide along the strike plate. The strike plate can be designed to be closed, in particular flat, in the area in which the control latch can be supported on the strike plate.

The solution according to the invention has the advantage that the door can be opened and closed again reliably, since undesired movement of the locking element from the unlocked position into the locked position when the door is open can be prevented. The fact that the latch actuator reliably holds the latch element in the unlocked position until the control latch has reached the protruding position ensures that the control latch initially assumes the position in which the latch element remains in the unlocked position before the latch element actuator stops the latch element hold in the unlocked position. Thus, in particular, an interaction between the locking element actuator and the locking element is only canceled when the locking element remains in the unlocked position even without the locking element actuator.

It is entirely possible that the control latch reaches the protruding position and still rests with a point on the strike plate, the locking element operator then stopping or being able to stop holding the locking element in the unlocked position. The locking element actuator is accordingly designed to hold the locking element in the unlocking position in the active position until the control latch has reached the protruding position, the control latch reaching the protruding position in that the lock, in particular the control latch opening of the lock, moves away from the strike plate .

For example, the lock can comprise a lock mechanism element, in particular a lock slide, by means of which the locking element is held in the unlocked position. In the projecting position, the control latch prevents the lock mechanism element from being movable in such a way that the locking element can be moved into the locking position.

The lock mechanism element can in particular be operatively connected to the locking element in such a way that a movement of the lock mechanism element from a first position into a second position causes a movement of the locking element from the unlocking position into the locking position. Additionally or alternatively, the movement of the lock mechanism element from the second position into the first position can bring about a movement of the locking element from the locking position into the unlocking position. In the projecting position, the control latch can cause the lock mechanism element to remain in the first position.

The locking element and the lock mechanism element can, for. B. interact with each other via a backdrop.

The locking element can be designed as a bolt, a latch or a latch bolt.

An actuating device of the counter-lock can be used to open and / or unlock the door, the active leaf door and / or the stationary leaf door, wherein the actuating device can also cause the bolt element actuator to move from the retracted position into the operative position.

The control latch opening can advantageously move away from the strike plate by an opening movement of the stationary and / or active leaf door. The control latch opening is removed from the strike plate in particular as a result of the increasing distance between the lock and the strike plate. This can be the case in particular if both the The active leaf door and the passive leaf door simultaneously open the door. A simultaneous opening movement can take place if the door is rebated and the door is opened via the fixed leaf door. In particular, the control latch can rest on the strike plate when it reaches the protruding position.

It is conceivable that when the door is closed, the movement of the locking element into the locking position is always activated. The lock can thus be designed as a self-locking lock. Here, the locking element can always be extended into the locking position when the lock is opposite the counter-lock. The lock can in particular be designed as an anti-panic lock. The lock can be unlocked mechanically by actuating a panic bar or a door handle. The panic bar and / or the door handle can be connected to the lock, in particular to an actuating element of the lock.

The counter lock can in particular be designed as a self-locking counter lock. In this case, at least one locking bar can always be moved from a retracted position into an extended position when the locking bar is located opposite a closing element for the locking bar. The locking bar can be connected to the counter lock. The counter lock can in particular be designed as an anti-panic counter lock. Both the fixed leaf door and the active leaf door can be opened by actuating a panic bar or a door handle on the counter lock, in particular the locking element actuator can move from the retracted position into the operative position. In addition, when a panic bar or a door handle is actuated, the locking bar can be moved from the extended position to the retracted position. The panic bar and / or the door handle can be connectable to the counter lock, in particular to an actuating element of the counter lock.

It is also conceivable that the movement of the locking element into the locking position takes place and / or is supported by a spring of the lock. This enables a mechanism, if necessary, in which the locking element changes from the unlocking position to the locking position when the control latch is in the retracted position and the locking element actuator is in the retracted position.

The locking element actuator can in particular be moved from the retracted position into the operative position and vice versa. In the retracted position, the locking element operator allows movement of the locking element into the locking position. In the operative position, the locking element actuator prevents the locking element from being able to assume the locking position. In the active position, the locking element actuator holds the locking element in the unlocked position. If the locking element is transferred from the locking position to the unlocking position by means of the counter lock, the locking element actuator in particular moves from the retracted position into the operative position.

In addition, it can be advantageous within the scope of the invention that the locking element actuator rests resiliently on the locking element in the operative position.

The locking element actuator can be designed in several parts, the locking element actuator preferably comprising an engagement element and an active element. The engagement element is preferred when an actuating device of the counter-lock moves. In the active position, the active element rests against the locking element. Here, the engagement element and the active element can be resiliently connected to one another. In this way, a position for resting on or a distance from the locking element can be compensated for in a flexible manner. This has the advantage that the mechanism can push the locking element out of the counter-lock housing particularly reliably via a movement of the locking element actuator and hold it in the unlocked position until the control latch protrudes Position. Here, the spring between the active element and the engagement element has to compensate for an ever-increasing gap between the lock and the strike plate.

It can optionally be possible for the locking element actuator to be movable in translation. The active element can be designed as an actuating pin, wherein in particular a spring of the locking element actuator is designed as a spiral spring.

The actuating pin can be designed to unblock the locking element. It is conceivable that the locking element is blocked in the locking position. A blocking element can be provided in the lock for this purpose. The active element can perform the deblocking, e.g. B. by the active element presses on a deblocking element of the locking element. The spring force of the spring can support the deblocking.

It can advantageously be provided in the invention that the active element is guided in the engagement element, in particular when the locking element actuator can be moved in a translatory manner.

The width of an end face of the active element can preferably be greater than a width of the active element in the interior of the engagement element. This achieves both guidance of the active element and a large width with which the active element rests on the locking element. The large width with which the locking element actuator rests on the locking element ensures that the locking element actuator holds the locking element in the unlocked position even with an increasing distance between the lock and the counter-lock. Furthermore, the geometric design and extension of the active element, that is to say in particular the width of the end face, can also be adapted to the locking element.

The active element and the engagement element can comprise mutually corresponding stop surfaces, the stop surfaces causing a movement of the Active element is limited from the attack element. The limitation of the movement serves in particular to ensure a reliable function, since the movement of the active element and possibly also a protrusion of the active element from the engagement element and / or from the counter lock housing in the active position on the arrangement of the counter lock in relation to the lock, in particular in the partially open state of the door and / or must be adapted to the design of the locking element.

It can preferably be provided within the scope of the invention that the locking element actuator with the engagement element and the active element can be pivoted about a first axis. The active element can be mounted on the engagement element so as to be pivotable about a second axis, the spring in particular being designed as a leaf spring. The spring is mounted between the active element and the engagement element. This enables a particularly space-saving design of the locking element actuator. It may be that the engagement element has a gate via which the engagement element can be pivoted. A counter-lock mechanism part connected to the actuating element of the counter-lock can engage in the link. Cause a movement of the counter-lock mechanism part in the backdrop to the movement of the attack element.

In a further possibility it can be provided that the control latch comprises a control latch head which is rotatably mounted and / or is provided with a tip. It is also advantageous if the control latch head is mounted in such a way that the rotation facilitates movement of the control latch into the projecting position. This simplifies the provision of the functionality of the control latch to protrude when the door is opened and thus, for example, to prevent the locking element from being transferred into the locking position when the door is at least partially open.

It can further be possible that a protruding portion of the locking element actuator that protrudes from the strike plate in the operative position is at least 45% Abrag portion of the control latch, with which the control latch protrudes from the lock in the projecting position, is, preferably, that the abrasion portion of the locking element actuator is at least 50% of the abrasion portion of the control latch, particularly preferred that the removal portion of the locking element actuator is at least 55% of the removal portion of the control latch amounts. As the upper limit, the Abgrag portion of the locking element actuator z. B. 100% of the Abragteil the tax trap. This has the advantage that the locking element is reliably held in the unlocking position during the opening process. In this case, the amount of removal of the bolt element actuator squared and / or the width of the strike plate or the counter lock squared approximately correspond to the amount of removal of the control trap squared. "About" means a range +/- 20%, preferably +/- 10%.

It is also optionally conceivable that the width of an end face of the locking element actuator and the width of an end face of the locking element are designed such that at least one edge of the end face of the locking element actuator, which is in particular facing the inside of the fixed leaf door, and one edge of the end face of the locking element, which can preferably be turned towards the outside of the active leaf door, lie against one another when the control latch is in the projecting position.

Particularly preferably, the end face of the locking element actuator is at least 80% of the width of the counter lock that of the strike plate. This has the advantage that during the opening process of the door, the locking element is reliably held in the unlocked position by the active element of the locking element actuator, as long as the control latch opening has not yet moved away from the strike plate and has reached the protruding position. In particular, only when the protruding position is reached can it be ensured that the locking element is held even without the locking element actuator and is not transferred into the locking position again, i.e. remains in the unlocking position.

It is also advantageous if a spring of the locking element actuator, in particular the spring force of the spring, is designed in such a way that the locking element actuator always rests resiliently on the locking element during the movement of the locking element into the unlocking position, in particular that the locking element actuator then rests resiliently on the locking element when the unlocking process is carried out against a preload (preferably on the locking element). It is advantageously provided here that the locking element corresponds to a bolt of the lock. In particular, the spring can be designed in such a way that it is possible for the locking element to be pushed out of the counter-lock housing even with a preload.

It can also be possible for the lock to include a latch. The latch can be moved into a locking position and an unlocking position.

In particular, the latch can be converted into a blocked state and into an unblocked state, with the latch preferably being movable into the unlocking position and / or blocked in the unblocked state when it rests on an edge of a latch opening of the counter lock or on a strike plate of the counter lock State a movement into the unlocked position is prevented. For example, the trap can be designed as a cross trap.

A spring of the locking element actuator, in particular the spring force of the spring, can be designed such that the locking element actuator rests resiliently on the locking element during the movement of the locking element into the unlocking position, while the latch is transferred to the unblocked state. Holding and / or pushing out the locking element by the locking element actuator has the advantage that the locking element actuator ensures that the lock element is transferred to the unblocked state. E.g. a corresponding mechanism is provided in the lock for this purpose, which enables this transfer to the unblocked state only when the locking element is moved into the unlocking position and / or when the locking element is in the unlocking position. This also enables a reliable opening of the unlocked door, since the trap z. B. can move away from the trap opening. E.g. the spring force is approximately 10 N or in a range from 8 N to 12 N (Newtons).

Furthermore, it is conceivable that the counter-lock comprises a counter-lock mechanism element, in particular a slide, the locking element actuator and / or a locking bar, in particular via a locking bar connection, being movable by means of the counter-locking mechanism element, in particular that the counter-locking mechanism element can be moved directly with the locking element actuator and / or with the locking rod and / or the locking rod connection is connected and / or contacted thereon. Alternatively or in addition, it may be possible for the counter-lock mechanism element to be connected to and / or to make contact with a second locking bar and / or a second locking bar connection via a lever. Preferably, the second locking bar or the second locking bar connection can be transferred from the extended to the retracted position or from a first to a second position via the lever by means of the counter-lock mechanism element. This allows an additional locking to further increase the security of the door.

A further advantage within the scope of the invention can be achieved if the locking element can only be moved into the locking position when both the latch are first moved into the unlocking position and the control latch is moved into the retracted position, whereby a stop element can change from a locking position to a release position Preferably, the stop element can be moved from the release position to the blocking position independently of the position of the latch by moving the control latch from the retracted position into the projecting position, in particular while the locking element is in the unlocking position. The lock can comprise the stop element.

In this way, the stop element can advantageously be designed in the blocking position for blocking a transfer of the locking element from the unlocking position into the locking position. For this purpose, the stop element z. B. engage in a recess of the locking element.

The stop element can be designed in the release position for releasing the transfer of the locking element from the unlocking position to the locking position. For example, the stop element can be in the release position out of engagement with the recess of the locking element.

For this purpose, the stop element can change from the locking position to the release position, for example by the mechanism in the lock, preferably in such a way that the movement of the locking element is blocked directly or indirectly by the stop element only in the locking position.

It is also optionally conceivable that the latch is designed with a movable latch head in such a way that the latch can be moved into the unlocking position, in particular when the active leaf door and / or the stationary leaf door is in contact with an edge of a latch opening or the strike plate. Alternatively or in combination, it may be possible that the latch can only be moved into the unlocking position by resting against the edge of the latch opening or the strike plate. In particular, the counter-lock can be designed free of a latch actuator.

Another advantage can be achieved within the scope of the invention if the lock comprises an electromechanical lock actuator and a control latch sensor, the locking element being held in the unlocked position by the lock actuator until it is detected by the control latch sensor that the control latch is in the protruding position is located. This also ensures that the lock will function reliably when the door is opened.

It is also conceivable within the scope of the invention that the lock comprises a locking element sensor and an alarm is generated when the control latch sensor detects that the control latch is in the protruding position and in particular the locking element sensor detects that the locking element is in the locking position. A faulty locking can thus be reliably determined.

Further advantages, features and details of the invention emerge from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings.

In the following figures, the same reference numerals are used for the same technical features from different exemplary embodiments.

In Figure 1 a counter lock 100 of a lock arrangement 500 according to the invention is shown schematically in a front view. The Figures 2 to 5 show the counter lock 100 in further perspectives. Such a counter lock 100 can preferably be used for a fixed leaf door, in which a lock 1 of an active leaf door is arranged adjacent to the counter lock 100. Such a lock 1 of a corresponding arrangement is therefore shown with dashed lines by way of example. It can be seen that an opening 110 for the locking element 20 in a counter-lock housing 170 can be formed at the position of a locking element 20 of the lock 1. In the same way, a corresponding opening 220, in particular latch opening 220, can be present in the counter-lock housing 170 at the position of a second locking element 70 (such as a latch 70). An interaction of the lock 1 and counter-lock 100 for locking is thus achieved. This arrangement is particularly suitable for escape doors or the like, since the actuation of one of the actuating elements 141 (a nut or the like), possibly via a panic bar, can trigger a mechanical interaction of the counter-lock 100 with the lock 1 for unlocking. A locking element actuator 130 of the counter lock 100 is an example here listed, which is arranged adjacent to the opening 110 in order to push the locking element 20 out of the counter-lock housing 170. The locking element actuator 130 of the counter lock 100 is moved from a retracted position into an operative position. In the figures, the latch actuator 130 is shown in the retracted position.

A mechanism of the counter-lock 100 can serve as an essential component for triggering this interaction, that is to say the unlocking of the lock 1 and the counter-lock 100. This uses a counter-lock mechanism element 160, which is preferably designed as a slide 160. By moving the slide 160, which is shown in FIG Figure 1 is designed as a translation guided in the counter-lock housing 170 (a pivoting movement or the like are also conceivable), further mechanical elements of the counter-lock 100 - and consequently also of the lock 1 - can be actuated or unlocked. As an example, the locking bars 520 of the counter lock 100, the locking element 20 and the latch 70 can be named, which will be discussed further below.

As an alternative or in addition to a locking element 20, at least one locking rod 520, ie z. B. a first locking rod 521 and a second locking rod 522 may be provided. These are connected to the associated locking bar connections 120 of the counter lock 100, in particular immovably and firmly. The locking bar connections 120 are movably received in the counter-lock housing 170 for moving the locking bars 520. In particular, a first locking rod connection 121 is provided for the first locking rod 521 and a second locking rod connection 122 is provided for the second locking rod 522. The respective locking bar connection 120 can be moved from a first position to a second position by means of the slide 160 of the counter-lock 100. In the first position, the locking rod 520 connected to the corresponding locking rod connection 120 can be extended and, in the second position, it can be retracted in the counter-lock housing 170. In the extended position, a lock z. B. made possible that the locking rod 520 in a Recording is introduced into a door frame, a wall, a ceiling, a floor or the like. For unlocking, that is to say the movement into the retracted position, the locking rod connection 120 must therefore be moved into the second position.

The slider 160 can be moved from a first position in which the at least one locking rod connection 120 is in the first position, and to a second position in which the at least one locking rod connection 120 is in the second position. The counter lock 100 can have at least one counter lock spring 180 which urges the slide 160 into the first position, the counter lock spring 180 engaging at least one of the bolt bar connections 120.

The slide 160 and the locking element actuator 130 are operatively connected to one another via a link guide.

The locking element actuator 130 can have one or more functions, such as the movement of the locking element 20 of the adjacent lock 1 of a lock arrangement 500 for unlocking and / or the protection against manipulation in the counter lock 100. As in FIG Figure 8 is shown on the basis of a lock arrangement 500 of a locking system 400, the locking element 20 can engage in the opening 110 of the counter-lock 100 in a locking position of the locking element 20. In addition, the lock 1 can comprise at least one control latch 50, for example with a rotatably mounted control latch head 51, the control latch 50 assuming a retracted position to move the locking element 20 into the locking position. In the projecting position of the control latch 50, on the other hand, the control latch 50 is mechanically prevented from moving into the locking position. To hold the control latch 50 in the retracted position, a striker plate 210 of the counter-lock 100 can be provided, so that closing the door leads to the control latch 50 being retracted and held by the striker plate 210.

The locking element actuator 130 of the counter lock 100 can be moved from the retracted position into the operative position. According to the invention, in the operative position, the locking element actuator 130 is designed to hold the locking element 20 in the unlocking position until a control latch opening moves away from the strike plate 210 and the control latch 50 has reached the protruding position.

In other words, it can be prevented that the locking element 20 is moved again into the locking position when the door is opened, that is to say when the stationary and / or active leaf is moved. It is true that the locking element 20 is always first transferred into the unlocking position by the locking element actuator 130. If the locking element actuator 130 were to come out of operative connection with the locking element 20 before the control latch 50 reached the protruding position, the locking element 20 would undesirably assume the locking position again. This is prevented according to the invention in that the locking element actuator 130 is carried along with the locking element until the control latch 50 has reached the protruding position.

The undesired return movement of the locking element 20 is caused by a lock mechanism element 33, which is designed as a slide 33. The slide 33 urges the locking element 20 into the locking position by means of a lock spring. Here, the slide 33 moves from a first position to a second position. The protruding position of the control latch 50, however, prevents the slide 33 from moving from the first position to the second position.

Furthermore, by moving into the active position, the locking element actuator 130 can press the locking element 20 out of the counter-lock housing 170 by means of an active element 131 in order, for example, to support an emergency opening. Both can be brought about mechanically by connecting the locking element actuator 130 to the slide 160, in that the slide 160 mechanically engages an engagement element 132 of the locking element actuator 130.

In Figure 9 and 10 the lock 1 is shown with further details, which is also part of the lock arrangement 500. It can be seen here that the lock 1 can have a lock housing 10 in which the slide 33 is movably guided. A lock actuator 30 with a lock gear 31 is also provided in order to move the slide 33 in particular. The lock also includes a nut 32 by means of which the lock can be unlocked mechanically.

The actuation of the slide 33 can also cause the unlocking of a latch 70 which has a latch head 71. The further slide 33 can serve to move and / or guide the locking element 20, which can be influenced by a state of the latch 70 and the control latch 50. So the locking element 20 z. B. can only be transferred into the locking position when first both the latch 70 and the control latch 50 are transferred to the retracted position. For this purpose, a stop element 80 can change from a blocking position to a release position. The stop element 80 can be moved independently of the position of the latch 70 from the release position into the blocking position by moving the control latch 50. As a result, the locking element 20 can already be held in the unlocked position when the control latch 50 has reached the protruding position, regardless of a position of the latch 70.

In the Figures 2 , 3 and 7th the latch actuator 130 is shown in greater detail. In the active position, the locking element actuator 130 rests resiliently on the locking element 20 and, for this purpose, is constructed in several parts with an engagement element 132 and an active element 131 with an end face 134. A movement of the actuating device 140 of the counter-lock 100 can move the engagement element 132 so that the active element 131 rests against the locking element 20 with the end face 134 in the active position. It is advantageous if the engagement element 132 and the active element 131 are resiliently connected to one another. A spring 135 of the locking element actuator 130 can be designed as a spiral spring for this purpose. As a further variant of the locking element actuator 130, which is shown in Figure 6 is shown, the engagement element 132 can be pivotable together with the active element 131 about a first axis 162, the active element 131 being mounted on the engagement element 132 such that it can pivot about a second axis 163. The spring 135, which creates a suspension between the engagement element 132 and the active element 131, is designed as a leaf spring (see FIG Figure 6 ). As in Figure 6 As shown, a counter-lock mechanism part 161 connected to the actuating element 141 of the counter-lock 100 can engage a link 164 of the engagement element 132. A movement of the counter-lock mechanism part 161 in the link 164 causes the engagement element 132 to pivot.

On the embodiment of Figures 1 to 5 and Figure 7 coming back, the active element 131 is guided in the engagement element 132, the width of an end face 134 of the active element 131 preferably being greater than a width of the active element 131 in the interior of the engagement element 132.

Furthermore, the active element 131 and the engagement element 132 can comprise mutually corresponding stop surfaces (that is, for example, a first stop surface 138 and a second stop surface 139), the stop surfaces limiting movement of the active element 131 out of the engagement element 132.

The width of the end face 134 of the locking element actuator 130 and the width of an end face 21 of the locking element 20 can also be designed such that at least one edge of the end face 134 of the locking element actuator 130, which can be turned towards the inside of the inactive leaf, and one edge of the end face 21 of the locking element 20, which can be turned towards the outside of the active leaf, lie against one another when the control latch 50 is in the projecting position.

Another benefit is obtainable when an in Figure 7 Shown Abragteil 137 of the locking element actuator 130, which in the operative position from a Striker 210 protrudes at least 45% of an in Figure 9 illustrated Abrag portion 52 of the control trap 50, with which the control trap 50 protrudes from the lock 1 in the protruding position.

The spring force of the spring 135 can be designed in such a way that the active element 131 always rests resiliently on the locking element 20, even if the unlocking is carried out against a preload. The resilient application also takes place when the trap 70 is transferred from a blocked state to an unblocked state. A spring force of approx. 10 N may be necessary for this.

It is also possible that the lock 1 according to Figure 8 a locking element sensor 650, and an alarm is generated when an in Figure 9 The control latch sensor 600 shown detects that the control latch 50 is in the protruding position and at the same time the locking element sensor 650 detects that the locking element 20 is in the locking position.

The locking element actuator 130 can furthermore comprise a blocking surface 133 which, in the retracted position, blocks a movement of at least one of the locking rod connections 120 into the second position. Unauthorized drawing in of the corresponding locking bar 520 can thus be prevented. In addition, the locking element actuator 130 can include a support surface 136 for guiding the slide 160.

In Figure 9 it is further made clear that the lock 1 can have an electromechanical lock actuator 30 for moving the locking element 20. The control trap sensor 600 can detect whether the control trap 50 is in the protruding position. Only then can the lock actuator terminate an operative connection with the slide, in particular in the first position.

It can also according to Figure 1 a counter lock actuator 142 for moving at least one of the locking rods 520 are activated in such a way that the Lock actuator 30 at least partially moves the locking element 20. In other words, the actuators of a locking system 400 can be controlled in a coordinated manner. For this purpose, z. B. an in Figure 8 The illustrated controller 510 can be used, which is integrated, for example, in a door drive 410 (outside a locking arrangement 500) and / or comprises a first control unit 511 in the lock 1 and / or a second control unit 512 in the counter-lock 100. In particular, the controller 510 is electrically connected to the lock actuator 30 and / or counter lock actuator 142 in order to activate the actuators.

As in Figure 2 and 3 As is also shown, it may be possible for at least one of the locking rod connections 120 to be connected to the slide 160 with a certain amount of play, and preferably to rest on a third projection 193 of the slide 160. This is used e.g. B. the manipulation protection in the event of an active movement (initiated from the outside via the locking rods 520) of the locking rod connection 120 in the direction of the interior of the counter-lock housing 170. Here, the locking rod connection 120 first comes to rest on a blocking surface 133 of the locking element actuator 130 before the movement is transmitted to the slide 160 is possible. The connection between the locking bar connection 120 and the slider 160 can also be designed such that the slider 160 first moves the locking element actuator 130 and only then moves the locking bar connection 120.

In Figure 1 and 7th it can be seen that at least one further of the locking rod connections 120 can be connected to the slide 160 via a lever 150. Such a lever 150, mounted in a pivot point 152, can transmit the movement of the slide 160 to this further locking rod connection 120. In particular, in this way, on the one hand via the lever 150 and on the other hand via the third projection 193, the movement of several (at least two) locking rod connections 120 via a single slide 160 is reliably possible.

The movement of a locking bar connection 120 can be brought about by actuating an actuating device 140, that is to say, for example, by actuating the actuating element 141 and / or an electromechanical counter-lock actuator 142. The actuating element 141 is, for. B. designed as a nut 141 and acts upon rotation on the slide 160. The counter-lock actuator 142 is z. B. designed as a motor and then has a counter lock gear 200, via which it can be operatively connected to the slide 160. It is shown as an example that the counter lock gear 200 comprises a cam 201, with the counter lock gear 200 with the cam 201 resting against the slide 160 when the counter lock actuator 142 is in operative connection with the slide 160. For this purpose, the slide 160 can comprise a first projection 191 on which the cam 201 comes to rest. To actuate the counter lock actuator 142, if this z. B. is designed as a motor, have an energy store 105 (as in Figure 8 is shown schematically). A control of the counter lock actuator 142 is z. B. via a controller 510, in particular a first control unit 511 of the lock 1 and / or a second control unit 512 of the counter-lock 100 is conceivable.

It is also conceivable that the actuating element 141 rests against a counter-lock mechanism element 160, in particular against a second projection 192 of the counter-lock mechanism element 160, when the counter-lock actuator 142 is in a rest state and the actuating element 141 is in an operating position (for example, the slide 160 can be understood as a counter-lock mechanism element 160 ). In this case, the actuating element 141 can become disconnected from the slide 160 by actuating the counter-lock actuator 142.

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

It is also possible that the slide 160 makes direct contact with and / or rests on the locking element actuator 130 and / or at least one of the locking rod connections 120, and the locking element actuator 130 can be moved by means of the slide 160, the locking element actuator 130 being driven by the slide 160 via a Link 195 is positively driven.

Next are in Figure 1 several openings 173 are shown, in which screw connections for fastening standard coverings can be introduced. For this purpose, the openings 173 can be arranged in such a way that they correspond to a specification for standard coverings. In particular, the screw connections can also serve to guide the slide 160, so that the openings have (at least) double functionality.
