EP3543436B1 - Counter lock for a passive door - Google Patents

Description

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

Doors with active and inactive leaf doors are known from the prior art, it being possible for a lock to be arranged in the active leaf door and a counterlock in the inactive leaf door. A lock usually includes a locking element which can be engaged with an opening of the counterlock. This enables the passive leaf door to be locked with the active leaf door. As a further locking measure, locking bars of the counterlock can be provided. Such are, for example, in engagement with a recess of a locking element in a door frame, a wall, a ceiling and / or in a floor to prevent the movement of the fixed leaf door of the door. The problem is that, under certain circumstances, manipulation to cancel this locking can be possible. Such tampering may include attempting to move a locking bar into the counterlock housing. In this way, the mechanism of the counter lock can be set in motion and cause unauthorized unlocking.

Counterlocks according to the state of the art also include many elements in order to mechanically and/or electromechanically bring about the movement of the locking rods and/or a pushing back of the locking element out of the counterlock.

In this context, from the EP 2 264 268 A an espagnolette lock for a door having a moving leaf, with a latch ejector, a control slide that can be displaced parallel to a forend, a latch ejector drive driven by the control slide, and a retraction slide for a drive rod. A coupler is provided, which drives the feed slide with a time delay when the control slide is actuated.

In addition, from the DE 36 36 236 A1 a panic lock for double-leaf doors is known, consisting of a panic lock with latch and deadbolt, which can be converted into the open position directly with an inside rotary handle on the one hand and indirectly with an outside rotary handle on the other after a key has been actuated, and a strike box whose forend plate is equipped with the latch and forms the locking plate cooperating with the bolt of the panic lock and has at least one driving rod which engages with its bolt end in a corresponding receptacle on the door frame and which can be converted into the open position only with an inside rotary handle against the action of a spring. To prevent it from returning to the locked position, the spring-loaded drive rod has a slide which is arranged in the strike box and can be displaced approximately at right angles to the direction of movement of the drive rod Effect of a spring is movable.

It is therefore an object of the present invention to at least partially eliminate at least one disadvantage described above. In particular, it is the object of the present invention to provide the locking and/or unlocking of the counter-lock in a simple and/or secure manner.

The above object is achieved by a counterlock with the features of claim 1. Further features and details of the invention result from the respective subclaims, the description and the drawings.

The task is solved in particular by a counter-lock for a fixed leaf door with a counter-lock housing and with a slide. The counter lock according to the invention further comprises a locking element actuator, and at least one first locking bar connection for connection to a first locking bar.

In this case, the slide is mounted on the counter-lock housing so that it can move in a translatory manner. The latch actuator is moveable from a retracted position to an operative position by the slider. In particular, it is provided that the first locking bar connection can be moved from a first position into a second position by means of the slide. The first locking bar can be moved into an extended position and into a retracted position by means of the first locking bar connection, the fixed leaf door being locked in the extended position and the locking caused by the first locking bar being released in the retracted position, wherein when the first locking bar moves in the stowed position, the first latch bar port is correspondingly in its second position. In other words, a mechanism of the counterlock can be provided which uses the slide to move the locking bar connection between the first and the second position. A simple solution can thus be provided in order to move several elements of the counter-lock by means of the slide. In particular, several unlocking processes can be carried out and/or locking processes can at least be permitted by means of the slide.

According to the invention it is provided that the locking element actuator comprises a blocking surface, wherein the locking element actuator in the retracted position blocks a movement of the first locking rod connection into the second position. Protection against manipulation can thus be provided, since it also prevents the locking bar from being pressed completely into the counter-lock housing and/or triggering the mechanism of the counter-lock for unlocking by the blocking surface

According to the invention, when the locking element actuator is in the operative position, the blocking surface allows the first locking rod connection to move from the first position to the second position, with the blocking surface of the locking element actuator providing a movement space for the first through the movement of the locking element actuator from the retracted position into the operative position Lock bar connection releases.

Advantageously, the slide and the locking bar connection as two separate parts formed, and can preferably be relative to each other be movably mounted in the counterlock housing. Advantageously, the slide and the locking element actuator are designed as two separate parts and can preferably be mounted in the counter-lock housing such that they can be moved relative to one another.

The slide can in particular be designed in one piece and/or made of the same material.

A first locking bar can preferably be connected to the first locking bar connection. The first lock bar is moveable by means of the first lock bar connector. The first latch bar is moveable to an extended position and a retracted position. In the extended position, the first latch bar is engaged with a first closure member. The first closing element is located in a door frame, in a floor or in a wall. Thus, in the extended position, the first locking bar serves to lock the inactive leaf door. In the retracted position, the first latch bar is disengaged from the closure member. Thus, the locking caused by the first locking bar is released in the retracted position. The first latch bar connector moves with the first latch bar. Accordingly, when the first latch bar is in the extended position, the first latch bar connector is in a first position. When the first latch bar is in the retracted position, the first latch bar port is correspondingly in a second position. The counterlock can include the first locking bar or be connectable to the first locking bar. Thus, any disclosure relating to moving and/or positioning the first latch bar to the stowed and/or extended position also includes a disclosure relating to moving and/or positioning the first latch bar port to the first and second positions.

The counterlock preferably comprises at least one second locking bar connection for connecting a second locking bar. The second locking bar is preferably movable by means of the second locking bar connection. The second latch bar is moveable to an extended position and a retracted position. In the extended position, the second latch bar is engaged with a second closure member. The second closing element is located in a door frame, in a floor or in a wall. The second locking bar is thus used in the extended position to lock the inactive leaf door. In the retracted position, the second locking bar is disengaged from the closing element. Thus, the locking caused by the second locking bar is released in the retracted position. The second latch bar connector moves with the second latch bar. Accordingly, when the second latch bar is in the extended position, the second latch bar port is in a first position. Accordingly, when the second latch bar is in the retracted position, the second latch bar port is in a second position. The counterlock can include the second locking bar or be connectable to the second locking bar. A disclosure regarding the movement and/or positioning of the second lock bar in the retracted and/or extended position also includes a disclosure regarding the movement and/or positioning of the second lock bar connector in the first and/or second position.

For example, the first locking bar can correspond to a lower locking bar. The second locking bar may correspond to an upper locking bar. The movements of the first and second locking rods into the extended and/or retracted position can be opposite to one another. The movement of the first lock bar port and the second lock bar port may be at least partially coupled. So it is conceivable that when the fixed leaf is unlocked, both the first locking bar and the second locking bar move from the respective extended position into the respective retracted position. During a locking operation, the first latch bar and the second latch bar move from their respective retracted positions to their respective extended positions. The first and second latch bar ports move accordingly.

In the case of the counterlock, the first locking bar connection can be provided as a lower locking bar connection for the first locking bar as a lower locking bar, in particular a driving bolt rod, and the second locking bar connection can be provided as an upper locking bar connection for the second locking bar as an upper locking bar, in particular a driving bolt bar. The Directional information refers to the installation position of the counterlock when installed. The locking bar connection serves to connect the respective locking bar in a counter-lock housing in order to move the locking bar by positioning the locking bar connection.

It may be that in the retracted position of the first and/or second locking bar, an energy accumulator is tensioned. It is conceivable that when the inactive leaf door is closed, the first and/or the second locking bar can be moved into the extended position by means of the energy accumulator. The counterlock can thus be designed to be self-locking.

For example, a spring element can be tensioned in the retracted position of the upper locking bar. The spring element can thus correspond to the force accumulator. The spring element can be arranged inside or outside of the counter-lock housing. The upper locking bar can be activated by a release element, e.g. B. a switching mechanism, be held in the retracted position with tensioned spring element. When closing the inactive leaf door, the triggering element, e.g. B. the key switch, the movement of the upper locking bar freely. The upper latch bar then moves to the extended position by means of the spring element.

The lower latch bar is allowed to move to the extended position by the force of a counterlock spring. The counter-lock spring can in particular be arranged in the counter-lock housing.

It can also be advantageous if the counter lock, in particular as an inactive leaf lock, can be arranged adjacent to the lock, in particular an active leaf lock, in order to accommodate a locking element of the lock for locking. For this purpose, the counter lock z. B. have a corresponding opening for the locking element. This allows a door which z. B. has a fixed leaf and a moving leaf, can be reliably locked.

The locking element actuator serves to move the locking element out of the counterlock housing. In particular, the lock includes the locking element. When the lock is in the locked state, the locking element engages in the opening of the counterlock. Here, the locking element is in a locking position. The latch actuator in the retracted position allows the latch to engage the opening. The latch actuator can move the latch from the locked position to an unlocked position by movement from the retracted position to the operative position. In the unlocked position of the locking element, the locking element is disengaged from the opening. In the active position, the locking element actuator can hold the locking element in the unlocked position as long as the lock and the counterlock are opposite one another. The locking element actuator can push the locking element out of the counter-lock housing by moving into the active position.

It is conceivable that the slide moves the locking rod connection and the locking element actuator at least partially at the same time. This makes it possible for the locking bar to be reliably retracted when the locking bar connection is moved by the slide, while the slide can at the same time move the locking element by means of the locking element actuator.

It is optionally provided that the counter-lock comprises an actuating device, with the locking rod being movable from an extended position into a retracted position by means of the actuating device, in particular by positioning the locking rod connection. The actuating device is designed, for example, as a nut and/or a lock cylinder and/or a motor for moving the locking bar.

According to the invention it is provided that the locking element actuator comprises a blocking surface, wherein the In the retracted position, the latch actuator blocks movement of the first latch bar terminal to the second position via the blocking surface. According to the invention, the locking rod connection is retracted further into the counter-lock housing in the second position than in the first position, so that the blocking surface can reliably prevent the associated locking rod from being retracted into the counter-lock housing. For this purpose, the blocking surface is designed for direct contact with the first locking rod connection in the retracted position of the locking element actuator, so that in this retracted position the blocking surface blocks further movement of the first locking rod connection. This provides protection against tampering, since the locking rod is also prevented from being pressed completely into the counter-lock housing and/or the mechanism of the counter-lock from being triggered for unlocking by the blocking surface. In particular, pressing in can only be permitted to the extent that play is provided between the locking rod connection and the slide.

According to the invention it is provided that the blocking surface, when the locking element actuator is in the operative position, allows a movement of the first locking bar connection from the first position into the second position. Advantageously, the blocking surface of the locking element actuator can release a movement space for the first locking rod connection due to the movement of the locking element actuator from the retracted position into the active position. This makes it possible for the first bolt connection to be able to move from the first to the second position as a result of the movement of the blocking surface.

Furthermore, it is possible within the scope of the invention that the locking element actuator and the first locking bar connection, in particular in the normal case, during the movement of the locking bar connection Latch bar from the first position to the second position are spaced from each other. In particular, when the locking element actuator is moved from the retracted position to the operative position by means of the slide and the first locking bar connection is moved from the first position to the second position, the latch actuator and first latch bar terminal may remain spaced apart. This reduces friction and wear of the locking bar connection and/or the locking element actuator.

In particular, the latch actuator may include a bearing surface for guiding the slider, the latch actuator bearing surface being configured such that the latch actuator and the latch bar connector are spaced apart during movement of the latch bar connector. For this purpose, for example, such a geometry of the locking element actuator can be provided that a movement path of the locking rod connection from the first to the second position is released when the slide moves the locking element actuator from the retracted to the active position. In the normal case, ie via the active movement by means of the slide, unlocking is thus reliably enabled. Advantageously, the blocking surface for blocking the movement of the first locking bar connection is not used in the normal case, but only in the case of manipulation.

For example, the support surface can be triangular in order to ensure both a sufficient support for guiding the slide and a sufficient distance.

The support surface can be used to guide the slide perpendicular to a direction of movement of the slide.

The slider may include movement means for coordinated movement of the latch member actuator and the first latch bar terminal. For example, the slide and the locking element actuator can be connected to one another via a link guide as a means of movement. The slider may include a protrusion as a moving means to move the first latch bar terminal.

In particular, the slider may first move the latch member actuator before the slider moves the latch bar port, preferably such that the blocking surface is moved out of the direction of movement of the latch bar port. This frees up the movement space for the movement of the locking bar connection in a simple and reliable manner.

It is also advantageous if, within the scope of the invention, the slide is connected to the first locking bar connection with play, in particular if the locking bar connection rests on a projection of the slide.

Preferably, it can also be provided with the counterlock according to the invention that the slide can be moved from a first position, in which the locking bar connection is in the first position, to a second position, in which the locking bar connection is in the second position, with preference being given to this the counter-lock comprises a counter-lock spring which urges the slide into the first position, with this counter-lock spring particularly preferably acting on the locking rod connection. In this way, the movement into the first position can always be provided as the preferred movement in order to further increase the security of the counterlock.

In particular, in the first position of the slide, the locking element actuator is in the retracted position. In the second position of the slide, the locking element actuator is in particular in the operative position. In particular, when the slider moves from the first position to the second position, the locking element actuator moves from the retracted position to the active position and vice versa. If the slider moves from the first position to the second position, the first and/or the second locking bar connection in particular moves from the first position to the second position.

It is also advantageous if the counterlock comprises the second locking bar connection, the second locking bar connection being connected to the slide via a lever. Advantageously, the second locking bar connection can be moved by the slide at least partially at the same time as the first locking bar connection. This enables locking on both sides. The lever can also have a fulcrum and/or be mounted on the counter-lock housing such that it can rotate and/or swivel via the fulcrum. This makes it possible to convert an upward movement of the slide into a downward movement of the second locking bar connection and thus also the second locking bar and/or vice versa, via the lever, in a reliable and cost-effective manner.

It can also be possible for the locking bar to be guided in a first, in particular front, and a second, in particular rear, counter-lock cover of the counter-lock housing. This provides reliable movement of the locking bar.

It can preferably be provided within the scope of the invention that the counter-lock comprises an electromechanical counter-lock actuator and an actuating element. The first and/or the second locking bar connection can be moved, in particular mechanically, by means of the actuating element via the slide. The first and/or the second locking bar connection can be moved by means of the counter-lock actuator via the slide. The actuating element can be designed as a nut and/or as a lock cylinder. The nut can be connected to a panic bar and/or a door handle. If a nut is provided as the actuating element, the counterlock can be designed as an anti-panic lock. The counter-lock actuator can be designed in particular as an electric motor.

Preferably, by actuating the actuating element, the slide can be disengaged from the counter-lock actuator. This enables mechanical emergency unlocking without the counter-lock actuator to harm. For example, the counter-lock actuator and the slide can be operatively connected to one another via a projection of the slide.

It is also advantageous if the electromechanical counter-lock actuator is arranged in the counter-lock housing. This enables secure actuation for locking and/or unlocking. For example, the counter-lock actuator is designed as an electric motor in order to unlock the counter-lock at least partially automatically, in particular to move the first and/or second locking bar from the extended position into the retracted position.

In addition, it can be advantageous within the scope of the invention that the counter-lock actuator can be operatively connected to the slide via a counter-lock gear, with the counter-lock gear being in an idle state of the counter-lock actuator out of operative connection with the slide, with the counter-lock gear in particular being in a rest position. This has the advantage that a mechanical movement of the first and/or second locking bar into the extended position and/or into the retracted position is not impeded by the counter-lock mechanism. In addition or as an alternative, it may be that a mechanical movement of the locking element actuator from the retracted position into the operative position and/or from the operative position into the retracted position is not impeded by the counterlock mechanism.

It can also be possible for the slide to be movable from the first position to the second position or from the second position to the first position without moving the counter-lock mechanism when the counter-lock actuator is in the idle state and/or when the counter-lock mechanism is in the idle position. This further improves the manual actuation.

According to a further advantage can be provided that the counter-lock mechanism includes a cam, wherein when the Counter-lock actuator is in operative connection with the slide, the transmission rests with the cam on the slide, in particular the slide comprises a first projection on which the cam comes to rest. The cam can preferably be out of operative connection with the slide, particularly preferably the first projection, when the counter-lock actuator is in the idle state. This frees up space for manual operation.

It is also advantageous if, within the scope of the invention, the actuating element is disengaged from the slide by actuating the counter-lock actuator. In particular, the actuating element can rest against the slide, particularly preferably against a second projection of the slide. In particular, the actuating element bears against the slide during an actuation of the actuating element. For this purpose, the actuating element can have an arm. The actuating element is preferably in contact with the slide when the counter-lock actuator is in the idle state. On the other hand, during an actuation of the slide by means of the counter-lock actuator, the slide detaches itself from the actuating element, in particular with the second projection. This prevents the counter-actuator from having to move the actuating element. As a result, the work to be performed by the counter-actuator can be kept low.

It may be that the slider includes a projection on which the gear, in particular the cam, can engage. In particular, the slide, in particular the projection, can be shaped in such a way that the gear, in particular the cam, coming from only one direction, in particular from a direction of rotation, can act on the slide, in particular on the projection. Additionally or alternatively, the slide, in particular the projection, can be shaped in such a way that the slide can always be moved by means of the nut. The slide, in particular the projection, can be shaped in such a way that a movement by which the cam could be brought into a position in which the cam blocks itself in the path of movement of the slide would, is prevented. In particular, a movement of the cam counter to a normal direction of rotation can be at least partially prevented.

A further advantage can be achieved within the scope of the invention in that the slide is directly connected to and/or contacted with the locking element actuator and/or the first locking rod connection. In particular, the locking element actuator can be moved by means of the slide, with the locking element actuator being positively guided by the slide, in particular via a connecting link.

Alternatively or additionally, it can be provided within the scope of the invention that the slide is forcibly guided on the counter-lock housing, with the slide preferably being forcibly guided at least twice. The slider can z. B. have at least one slot, preferably several slots for guidance. The guide through the slots serve in particular as a guide in the direction of movement of the slide.

It is possible for a fulcrum of the lever to also serve as a guide element for the slide, with the fulcrum in particular engaging in a slot in the slide. These measures allow a space-saving and secure mechanism to be used for unlocking.

Another advantage can be that the counterlock housing includes openings for attaching standard fittings. A passage can follow an opening, in particular connecting openings to one another. At least one passage is preferably arranged in a recess or a slot in the slide, with the passage being used in particular to guide the slide. The bushing can accommodate a screw connection. This means that standard fittings can be attached in a space-saving manner. In this context, standard fittings are preferably understood to mean those fittings which are used on such a door in a standardized manner come. For this purpose, the fittings preferably have standardized geometries and/or positions for fastening means.

It may be that the counter lock is designed without a latch actuator. Rather, a latch of the lock can be unlocked at the same time as the locking element moves into the unlocking position. In particular, the movement of the latch into the lock housing can be released at the same time as a movement of the locking element into the unlocked position. The trap can e.g. B. be designed as a cross latch.

Further advantages, features and details of the invention result 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 numbers are used for the same technical features of different exemplary embodiments.

In figure 1 a counter lock 100 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 in which a lock 1 of a moving leaf is arranged adjacent to the counter-lock 100 . Such a lock 1 of a corresponding arrangement is therefore shown by dashed lines as an example. It can be seen that an opening 110 for the locking element 20 can be formed in a counter-lock housing 170 at the position of a locking element 20 of the lock 1 . Likewise, a corresponding opening 220, in particular latch opening 220, can be present in counter-lock housing 170 at the position of a second locking element 70, such as a latch 70. Thus, an interaction of the lock 1 and counter-lock 100 for locking is achieved. This arrangement is particularly suitable for escape doors or the like, since the Actuation of one of the actuating elements 141, in particular 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 mentioned here as an example, 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 hereby 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, ie the unlocking of the lock 1 and the counter-lock 100 . This uses a slide 160. By moving the slide 160, which in figure 1 as a translatory movement guided in the counter-lock housing 170, according to the invention, in addition to the locking element actuator 130, other mechanical elements of the counter-lock 100—and consequently also of the lock 1—can be actuated or unlocked. As an example, locking rods 520 of the counterlock 100, the locking element 20 and the latch 70 can be mentioned here, which will be discussed in more detail below.

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

The slider 160 is movable from a first position in which the at least one lock bar port 120 is in the first position and to a second position in which the at least one lock bar port 120 is in the second position. Here, 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 acting on at least one of the locking bar connections 120 .

As in figure 2 and 3 is further shown, it may be possible that at least one of the locking bar connections 120, in particular the lower locking bar connection, is connected to the slide 160 with play, and preferably rests on a third projection 193 of the slide 160. This serves e.g. B. protection against tampering 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 counterlock housing 170. The lower locking rod connection 120 then first comes to rest on a blocking surface 133 of the locking element actuator 130 before the transfer of the Movement to the slider 160 is possible. Latch actuator 130 is now in the retracted position. When the latch actuator 130 moves from the retracted position to the operative position, the blocking surface 133 becomes out of the direction of movement of the latch bar connector 120. Thus, the latch bar connector 120 can be moved from the first position to the second position. However, the movement of the locking element actuator 130 is only possible if a actuating device 140 and not by manipulating the lower locking bar 521.

The connection between the locking bar connector 120 and the slider 160 is designed such that the slider 160 first moves the locking element actuator 130 and only then moves the locking bar connector 120 . Latch actuator 130 and lower latch bar terminal 120 remain spaced apart during movement of slider 160 .

In addition, the locking element actuator 130 can include a bearing surface 136 for guiding the slider 160 . The guidance is transverse to the direction of movement of the slider 160 from the first position to the second position. The bearing surface 136 is configured such that the latch actuator 130 and the lower latch bar terminal 120 remain spaced apart during movement.

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

The movement of a locking bar connection 120 can be brought about by actuating an actuating device 140, ie for example by actuating the actuating element 141 and/or an electromechanical counter-lock actuator 142. The actuating element 141 is z. B. formed as a nut 141 and acts on the slide 160 during rotation. B. designed as an electric motor. The counter-lock actuator 142 drives a counter-lock gear 200 via which the Counter lock actuator 142 with the slide 160 is operatively connected. It is shown by way of example that the counter-lock mechanism 200 includes a cam 201 , when the counter-lock actuator 142 is in operative connection with the slide 160 , the counter-lock mechanism 200 rests with the cam 201 on the slider 160 . For this purpose, the slide 160 can comprise a first projection 191 on which the cam 201 comes to rest. If the slide 160 is actuated by means of the actuating element 141, the slide 160 can detach from the cam 201, so that the counter-lock actuator 142 is not damaged in the event of a mechanical override by the actuating element 141.

Preferably, the cam 201 is in a rest position of the counter-lock actuator 142 out of operative connection with the slide 160. In this case, there is a rest position when the counter-lock actuator 142 is not performing any work. This prevents damage to the counter-lock actuator 142 when the slide 160 is moved by the counter-lock spring 180 or the actuating element 141 .

Figure 4A shows a modified form of the slide 160. In this case, the first projection 191 has a bulge 196. The bulge 196 prevents the cam 201 from being able to be located above the first projection 191 during a counterclockwise movement and thus blocking a movement of the slide 160 from the first position into the second position. Bulge 196 allows only clockwise movement of cam 201 to engage first projection 191 . Thus, the bulge 196 always ensures a movement of the slide 160 from the first to the second position.

The counter lock actuator is arranged in the counter lock housing 170 .

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 shown schematically). A control of the counter-lock actuator 142 is z. B. about 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.

The energy store 105 can be used to disengage the cam 201 from the slide 160 when the counter-lock actuator 142 is in a resting state in the event of a power failure.

It is also conceivable that the actuating element 141 bears against the slide 160 , in particular against a second projection 192 of the slide 160 , when the counter-lock actuator 142 is in a resting state and the actuating element 141 is in an actuating position. The actuating element 141 can be disengaged from the slide 160 by actuating the counter-lock actuator 142 . Here, the slide 160 with the projection 192 is released from the actuating element 141.

The slide 160 can be forcibly guided on the counter-lock housing 170, in particular twice forcibly guided. The slide 160 can have at least one elongated hole 194 for guidance, in which case the pivot point 152 of the lever 150 can also serve as a guide element for the slide 160 .

It is also possible for slide 160 to make direct contact with and/or rest on locking element actuator 130 and/or at least one of locking rod connections 120, and for locking element actuator 130 to be movable by means of slide 160, with locking element actuator 130 being moved by slide 160 via a Setting 195 is forcibly guided.

Next are in figure 1 several bushings 173 are shown, in which screw connections for fastening standard coverings can be introduced. For this purpose, an arrangement of the leadthroughs 173 can be provided that corresponds to a specification for standard coverings. In particular, the bushings 173 for Guide the slide 160 are used, so that there is at least a dual functionality of the bushings 173.

The locking element actuator 130 can also have one or more functions, such as the movement of a locking element 20 of an adjacent lock 1 of a lock arrangement 700 for unlocking and/or protection against tampering with the counter lock 100 and/or a locking arrangement 500. As in figure 8 is shown using a lock arrangement 700 of a locking system 400, the locking element 20 can engage in a locking position of the locking element 20 in an opening 110 of the counter-lock 100. In addition, the lock 1 can include at least one control latch 50, for example with a rotatably mounted control latch head 51, the control latch 50 assuming a retracted position for the movement of the locking element 20 into the locking position. In contrast, in a protruding position of the control latch 50, the movement of the locking element 20 into the locking position is mechanically prevented. To hold the control latch 50 in the retracted position, a locking plate 210 of the counter-lock 100 can be provided, so that closing the door results in the control latch 50 being retracted and held by the locking plate 210 . The latch actuator 130 of the counterlock 100 can be moved from the retracted position to the operative position. This takes place in particular when the actuating device 140 is actuated, so that the locking element actuator 130 can unlock the lock from the counter-lock on the fixed leaf door. In the active position, the locking element actuator 130 is designed to hold the locking element 20 in the unlocked position until the control latch 50 has moved away from the locking plate 210 and has reached the protruding position. In other words, the locking element 20 can be prevented from locking when the door is opened, ie when the fixed and/or active leaf is moved. Furthermore, in the retracted position, the locking element actuator 130 can push the locking element 20 out of the counter-lock housing 170 by means of an operating element 131 by moving into the active position, in order to support or achieve an emergency opening from the fixed leaf door side, for example. Both can through the Connection of the locking element actuator 130 to the slide 160 can be effected mechanically by the slide 160 mechanically engaging an engaging element 132 of the locking element actuator 130 .

In figure 9 it is further clarified that the lock 1 can have an electromechanical lock actuator 30 for moving the locking element 20 . It can also be in accordance with figure 1 a counter-lock actuator 142 for moving at least one of the locking rods 520 can be 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. one in figure 8 illustrated controller 510 can be used, which is integrated, for example, in a door drive 410 outside of a locking arrangement 500 and/or comprises a first control unit 511 in lock 1 and/or a second control unit 512 in counter-lock 100. In particular, the controller 510 is electrically connected to the lock actuator 30 and/or counterlock actuator 142 in order to activate the actuators. The locking arrangement 500 according to the invention comprises the lock 1 and the counter-lock 100.

In figure 9 and 10 the lock 1 is shown in more detail, which can also be part of a locking arrangement 500 according to the invention. Here it can be seen that the lock 1 can have a lock housing 10 in which a further slide 33 is movably guided. A lock actuator 30 with a lock mechanism 31 is also provided in order to move the additional slide 33 in particular. This can also bring about the unlocking of a latch 70, which has a latch head 71 for locking. The further slide 33 can be used 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. Thus, the locking element 20 z. B. only be transferred to the locked position if first both the latch 70 in the unlocked position and the control latch 50 are converted into the retracted position. For this purpose, a stop element 80 can move from a blocked position to change a release position, the stop element 80 being movable independently of the position of the latch 70 by a movement of the control latch 50 .

Furthermore, it is possible that the lock 1 according to figure 8 includes 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.

In the figures 2 , 3 and 7 Figure 1 shows the latch actuator 130 in more detail. In the operative position, the locking element actuator 130 is located e.g. B. resiliently on the locking element 20, and for this purpose is in several parts with an engagement element 132 and an active element 131 (with an end face 134) is formed. A movement of the actuating device 140 of the counter-lock 100 can move the engaging element 132 so that the active element 131 rests against the locking element 20 with the end face 134 in the active position. Further, the latch actuator 130 may include the blocking surface 133 which, in the retracted position, blocks movement of at least one of the latch bar terminals 120 to the second position. Unauthorized retraction of the corresponding locking bar 520 can thus be prevented. It is advantageous if the engagement element 132 and the active element 131 are resiliently connected to one another. For this purpose, a spring 135 of the locking element actuator 130 can be designed as a spiral spring. As a further embodiment variant of the locking element actuator 130, the engagement element 132 can be pivotable about a first axis, with the active element 131 being mounted on the engagement element 132 such that it can pivot about a second axis, and the spring 135 being designed as a leaf spring (see figure 6 ).

The active element 131 is advantageously guided in the engagement element 132, with the width of an end face 134 of the active element 131 preferably being greater than a width of the active element 131 inside the engagement element 132. Furthermore, the active element 131 and the engagement element 132 can face each other corresponding stop surfaces (ie, for example, a first stop surface 138 and a second stop surface 139), wherein a movement of the active element 131 from the engagement element 132 is limited by the stop surfaces. The width of end face 134 of locking element actuator 130 and the width of an end face 21 of locking element 20 can also be configured such that at least one edge of end face 134 of locking element actuator 130, which can be turned toward the inside of the fixed leaf, and one edge of end face 21 of the locking element 20, which can be turned towards the outside of the active leaf, abut when the control latch 50 is in the protruding position.

The above explanation of the embodiments describes the present invention exclusively in the context of examples.
