The invention provides two basic versions for the construction and functioning of the anti-tamper devices according to the invention:

This subject additionally or alternatively provides for the design principle no. 1 for the lower locking bar, namely in that the anti-tamper device has a blocking element which is movably mounted in the lock case and which, in the event of tampering pressure being applied to the lower locking bar, preferably blocks the lower locking bar connection device directly, without that the blocking element acts directly on the lock mechanism. A special embodiment that is designed accordingly is in Figures 10a, 10b and 10c shown.

In the case of design principle no. 1, there are particular advantages if it is provided that the blocking element is designed as a blocking lever which can be pivoted in a bearing fixed in the lock case and that the lower locking rod connection device is locked with a gear element of the lock gear, preferably a gear slide connected is. In this context, it can be provided that the lower locking rod connection device and the gear element can be coupled via the blocking lever and that in the event of manipulation pressure being applied to the lower end of the lower locking rod in the retraction direction of the blocking lever, the lower locking rod connection device is blocked in the direction against a sliding movement upwards; this is in the embodiment of the figures, 10a, 10b and 10c shown as an example.

In modified versions, this design can be provided accordingly for the upper locking bar. This means that in these designs the blocking element is designed as a blocking lever which is pivotally mounted in a bearing fixed in the lock case and that the upper locking rod device is connected to a gear element of the lock gear, preferably a gear slide, so that it cannot move. In this case, the upper locking rod connection device and the gear element can be coupled via the blocking lever and, in the event of manipulation pressure being applied to the upper end of the upper locking rod in the retraction direction of the blocking lever, the upper locking rod connection device can be blocked against a downward sliding movement.

In the embodiments mentioned, the blocking lever can preferably be acted upon by gravity in the blocking direction and interact directly with the transmission element of the lock mechanism, preferably the driver fixed to the transmission slide. The blocking lever can rotate against the force of gravity in the release direction when the gear element, preferably the gear slide, is displaced in the unlocking direction.

For this purpose, it can be provided that the upper locking rod connecting device is connected to the lock mechanism, preferably a gear slide of the lock mechanism, via a connecting link mechanism. However, it can also be provided that the lower locking rod connection device is connected to the lock gear, preferably the gear slide of the lock gear, via a connecting link device. An embodiment of the connecting link device can be provided for cooperation between the upper locking rod connection device and the lock mechanism or between the lower locking rod connection device and the lock mechanism. According to one embodiment a of these designs, the link slot is connected to the relevant locking rod connection device in a non-moving manner and the link pin is connected to the gear slide via a reversing gear. According to an embodiment b, the link slot is connected to the lock gear so that it cannot move, and the link pin is connected to the locking rod connection device in question via a reversing gear.

The upper locking bar connection device or the lower locking bar connection device can be connected to the lock mechanism via a connecting link device. According to an embodiment a, the link pin is connected to the locking rod connection device in question in such a way that it cannot move, and the link slot in one Arranged reversing gear of the upper locking rod connection device. According to an embodiment b, the link pin is connected to the lock gear so that it cannot move, and the link pin is formed in a reversing gear of the upper locking rod connection device.

In each of the embodiments, the reversing gear mentioned can be designed as a lever device that is mounted in a pivot bearing that is fixed in the lock case.

In the various designs mentioned, the lock gear is preferably designed as a gear with a gear slide, i.e. the named gear element is designed as a gear slide, which is connected at one end to the lower locking bar connection device and at its other end to the upper locking bar connection device is at least gearedly connected and is slidable in a first direction to unlock the lower and upper latch bars and slidable in a second direction to lock and latch the lower and upper latch bars. This first direction is 180° opposite to the second direction. For this purpose, a reversing gear is formed between the gear slide either for connection to the upper locking rod connection device or for connection to the lower locking rod connection device.

Certain versions provide that the lock mechanism of the passive leaf lock device has a latch lifting device for unlocking and/or retracting a latch, namely a lock latch or latch bolt of an active leaf lock device that can be mounted in and/or on the active leaf. Additionally or alternatively, the lock mechanism can also have a bolt lifting device for unlocking and/or retracting a bolt of an active leaf lock device that can be mounted in and/or on the active leaf. The lifting devices can preferably be actuated with the same lock actuating mechanism with which the upper locking bar and the lower locking bar are also actuated.

Of particular advantage are designs in which the lifting devices have a sensor device in order to detect whether or not the latch or bolt of the active leaf lock device engages in a predetermined space of the passive leaf lock device. Depending on the result of this detection of electrical signals, the sensor device can emit an electrical signal processing device. With the sensor device, an advantageous control and monitoring of the lifting devices of the wing and latch is possible. Furthermore, the sensor device can be used to monitor the closed and locked position of the door. In particularly preferred embodiments, the passive wing lock device is designed as a mortise lock and preferably the active wing lock device is also designed as a mortise lock.

The structure and functions of the passive wing lock device

The exemplary embodiments illustrated in the figures are different exemplary embodiments of passive leaf lock devices 30 which are each mounted in a passive leaf 110 of a double-leaf door. These passive wing lock devices 30 are each intended to interact with an active wing lock device, which is to be installed in an active wing of the double-leaf door in a correspondingly assigned manner.

An embodiment of an active wing lock device 1 mounted in an active wing 10 of a double-leaf door is in the Figures 1a to 1c shown in your interaction with an associated passive wing lock device, which is mounted in the passive wing 110.

The non-inventive passive wing lock device 30 of Figures 1a . 1b and 1c has a lock mechanism that is mounted in a lock case 30a. The lock case 30a is fitted in a receiving pocket in the passive wing 110. The lock mechanism comprises a lock gear with a gear slide 36 which is geared to a lock follower 37 rotatably mounted in the lock case 30a. Over a not shown actuating handle, which can be coupled in the lock follower 37 by plugging in, the gear slide 36 of the lock gear can be driven. The gear slide 36 is guided vertically in the lock case and can be moved up and down.

The passive wing lock device 30 comprises an upper and a lower locking rod 380o, 380u and lifting devices 31 and 32 in order to lift the latch 11 and the bolt 12 of an associated active wing lock device, which engage in the passive wing lock device in the locked position. The lock gear with the gear slide 36 is used to drive the upper locking bar 380o and the lower locking bar 380u and to drive the lifting devices 31 and 32. The design and function of the lifting devices 31 and 32 are explained in detail below in connection with the figures.

As in the Figures 1a , 1b and 1c As can be seen, the upper latch bar 380o is coupled to an upper latch bar connector 38o mounted in the upper portion of the lock case 30a. This upper connection device 38o is connected to the gear slide 36 via a reversing gear 36g. In the case shown in the figures, the reversing gear 36g is a toothed gear. For this purpose, the upper end piece of the gear slide 36 is designed as a toothed rack and the upper locking rod connection piece 380 also has a toothed rack. Between the two toothed racks, a toothed wheel device is rotatably mounted in a rotary bearing fixed to the lock housing. The toothed wheel device meshes with the toothed racks of gear slide 36 and locking rod connection device 38o, which are linearly guided in the vertical direction in the lock housing. The two racks are aligned in parallel facing each other with gear means interposed so that the two racks move in opposite directions in the vertical direction. This means that when the gear slide 36 is moved upwards, the upper locking rod connection device 38o is moved down and the locking rod connection device 38o is moved up by moving the gear slide 36 downwards.

The lower locking bar 380u is coupled to a lower locking bar connector 38u mounted in the lower portion of the lock case 30a. This lower locking rod connection device 38u is coupled in the same direction to the gear slide 36, so that when the gear slide 36 is moved upwards, the lower locking rod connection device is also moved upwards, and when the gear slide 36 is moved downwards, the locking rod connection device 38u is also moved downwards.

The locking rods 380o and 380u driven in this way are mounted vertically on the passive wing 110 and are linearly displaceable in each case in a corresponding vertical linear guide, preferably concealed within the passive wing. The locking rods 380o and 380u can be moved vertically up and down in opposite directions by their motion-fixed coupling to their associated connection device 38o or 38u via the actuation of the gear slide 36 .

The upper end of the upper latch bar 380o cooperates with a latch receiving recess formed in the upper post of the door's stationary frame. The lower end of the lower latch bar 380u cooperates with a latch receiving recess formed in the floor. In the extended position of the upper locking bar 380o, the free upper end of the locking bar engages in the upper lock receiving recess. In the extended position of the lower latch bar 380u, the free lower end of the latch bar engages the lower latch receiving recess.

By actuating the lock gear, in which the gear slide 36 is moved vertically as described, not only the upper locking rod 380o and the lower locking rod 380u are extended and retracted, but also those interacting with the latch 11 and the bolt 22 of the active leaf lock device Facilities 31 and 32 actuated.

As already mentioned, the case lifting device 31 serves to interact with the lock case 11 of the active wing lock device 1. The interaction consists in the case lifting device 31 returning the lock case 11 to the lock case 1a of the active wing lock device 1, in which the case Lifting device 31 pressurizes the lock latch 11 and thereby pushes it back until the lock latch 11 is fully inserted into the lock case 1a of the active wing lock device 1 . For this purpose, the case-lifting device 31 has a case-actuating slide 31a, which is driven by the gear slide 36 via a lever device 31h. When the gear slide 36 is pushed upwards, the lever device 31h is swung out so that the latch actuating slide 31a extends. When the gear slide 36 is pushed down, the lever device 31h is swiveled in so that the latch actuating slide 31a is retracted again.

The bolt lifting device 32 is used to unlock and retract the bolt 22 of the active lock device 1. The bolt lifting device 32 has a bolt actuating slide 32a in a corresponding manner, which is drive-connected to the gear slide 36 via a lever mechanism 32h. When the lever device 32h is pivoted out by actuating the gear slide 36, the bolt actuating slide 32a is extended. Then, under the action of the bolt actuating slide 32a, the bolt 22 engaging in the lock case 30a in its extended locking position is unlocked and then retracted into the lock case 1a of the active lock device. Unlocking takes place by applying pressure to the release pin 22a projecting beyond the end face of the bolt 32. After the bolt 22 is unlocked, it is further pressurized, which acts on the front of the bolt 22, retracted into the lock case 1a of the active wing lock device. When the lever mechanism 32h pivots back, the bolt actuating slide 32a is then retracted. This is done in that the gear slide 36 is moved downwards in the vertical direction.

As in the Figures 1a , 1b and 1c recognizable, a linear guide device 32b of the bolt actuating slide 32a is provided in the lock case 30a. The linear guide device 32b is directed horizontally in the lock case 30, so that the bolt actuating slide 32a can be guided in and out horizontally. A correspondingly linear guide device can also be designed for the case-actuating slide 31a of the lever device 31 in the lock case 30a, as is the case, for. Tie Figures 6a and 6b is shown for the embodiment shown there.

The bolt lifting device 32 is also referred to as a bolt unlocking and/or retraction device. You can be designed both for unlocking and for retracting the bolt, as in the Figures 1a , 1b and 1c case shown. In other exemplary embodiments, however, the bolt lifting device 32 can also be designed merely as a bolt retraction device. A separate device or at least a separate unlocking mechanism can be provided for the unlocking, which can optionally also be driven as a time delay by the gear slide 36 via the same lever device 32h or another separate lever device or via another gear. This is particularly true when the bolt 22 is not provided with a release pin mounted in the bolt, ie when another release element, e.g. B. separately from the bolt 22, z. B. a separate auxiliary latch on the active wing 10 or on the lock case 1a is provided.
In modified exemplary embodiments, the bolt lifting device 32 can also be designed merely as an unlocking device, ie the bolt actuating slide 32a can then switch off the locking by applying pressure to the triggering mechanism accordingly. The retraction of the bolt can optionally by another mechanism such. B. with a corresponding spring loading of the bolt. The spring device in question can be supported on the lock case 1a of the active leaf lock device but also on the passive leaf lock case 1a.

The case-lifting device 31 is also referred to as a case-unlocking and/or reversing device. You can, as in the Figures 1a , 1b and 1c illustrated case, be designed only as a case retraction device, specifically for a case 11, which is designed as a spring-loaded conventional latch bolt in the extension direction, which is not self-locking. The spring-loaded lock latch 11 has a prism-shaped end section which has an inlet slope, so that when the active leaf 10 is pulled shut, i.e. when the active leaf 10 is pulled or pushed into the closed position, the lock latch 11 strikes the frame of the passive leaf 110 with the inlet slope and counter to the spring loading the lock latch 11 is retracted. The slope of the lock latch 11 facing away from the entry slope is not designed as a slope, but as a blocking surface directed parallel to the plane of the sash, so that active operation of the lock latch 11 is required to open the door or, in a modified version, in which the lock latch 11 is equipped with a Electric strike latch interacts, the electric strike latch is actuated. In such modified designs, an electric door opener can be arranged in the passive wing lock device. The lock latch 11 can then interact with the door latch and the door can be released from the closed position by electrical actuation of the door latch.

At opposite the Figures 1a , 1b and 1c In modified versions, the lock latch 11 can also be designed as a self-locking lock latch—as a so-called latch bolt. The latch bolt can assume three positions, namely a first position retracted into the lock case 1a, a second position extended out of the lock case comparable to the extended position in conventional lock latches and a third position in which the latch bolt is extended far and locked at the same time and/or at least seems locked. In this third position, the latch bolt is about twice as far extended as a conventional lock latch in its extended position. In addition, the latch bolt, as already mentioned, is locked in this far extended third position. Reference is made to the Figures 7a and 7b , which show an exemplary embodiment not according to the invention, in which the latch 11 is designed as such a latch bolt. In this exemplary embodiment, the case lifting device 31 is designed as a case unlocking and retracting device, ie the case actuating slide 31a serves to unlock the latch bolt 11 in a first phase of the lifting process and to retract the latch bolt in the further course of the lifting process. Unlocking takes place in that the release pin 11a, which is movably mounted in the latch bolt, is first retracted by the case actuating slide 31a, ie first the free end of the release pin 11a protruding from the latch bolt 11 in the locked position is retracted by the case actuating slide 31a . The retraction unlocks the bolt 11, so that the latch bolt is retracted under further pressure from the latch actuating slide 31a. Modified versions with a latch bolt are also possible, in which the latch lifting device 31 is designed only as an unlocking device or only as a retraction device. In these cases, reversing or unlocking can take place via a separate device. The same applies as described above for the bolt lifting device 32 in connection with the unlocking or moving back of the bolt.

In the case of double-leaf doors, there is a certain play with a gap in the closed position of the double-leaf door between the passive wing and the active wing cannot be ruled out. For this purpose, in the embodiment of Figures 1a , 1b and 1c the latch actuating slide 32a has a spring-loaded pressure piece 32c. In this exemplary embodiment, the pressure piece 32c is resiliently supported via a helical compression spring on the plate-shaped base body of the bolt actuating slide 32a. The pressure piece 32c, like the plate-shaped base body of the bolt actuating slide 32a, is guided horizontally in the linear guide device 32b, which is formed in the lock case 30a. The horizontal guide results in a jam-free linear sliding movement and exact positioning of the actuating slide 32a and the pressure piece 32c over the entire travel path and thus a safe, precisely positioned return movement of the bolt 22. The spring loading of the pressure piece ensures that the lifting device 32 works properly, even for Versions of double-leaf doors with a relatively large tolerance range with a gap between the passive leaf and the active leaf.

In the figures 2a and 2 B is a versus the Figures 1a , 1b and 1c modified embodiment not according to the invention shown, in which the case-lifting device 31 is modified. The latch actuating slide 31a has an actuating plate which is linked to an actuating lever of the lever mechanism 31b on the driven side. The actuating lever has a pivot bearing which is fixed in the lock case 30a and is comparable to the Figures 1a , 1b and 1c actuated by the gear slide 36, but structurally modified in that a pressure pin mounted on the actuating lever is guided in a slot in the gear slide 36. In the embodiment in the Figures 1a , 1b and 1c a control edge of the gear slide 36 acts together with the pressure pin of the actuating lever, the control edge being formed in the edge contour of the control slide 36 .

In the figures 3a and 3b is a versus the Figures 1a , 1b and 1c modified non-inventive embodiment shown in which the bolt lifting device 32 is modified. The bolt actuating slide 32a has a plate-shaped base body which is guided horizontally at the edge in the linear guide device 32b fixed in the lock case 30a. The operating lever of the operating gear 32h is similar to that in FIGS figures 2a and 2 B guided in a slot in the gear slide 36 with the pressure pin mounted on the gear lever.

That in the Figures 6a and 6b shown non-inventive embodiment of the passive wing lock device 30 is compared to the embodiment of Figures 1a , 1b and 1c modified in that the lock gear is modified with the gear slide 36. The gear slide 36 is not driven via a gear with the upper locking rod connection device 38o mounted in the upper lock housing, but is coupled via a lever gear that reverses the direction of movement in a corresponding manner.

The bolt-lifting device 32 is structurally similar to the embodiment of FIG figures 3a and 3b .

The sensor devices

The case-lifting device 31 is in the embodiment of Figures 6a and 6b and the embodiment of Figures 7a to 7d compared to the embodiments of Figures 1a , 1b and 1c and the figures 2a and 2 B modified in that the latch-lifting device 31 has a sensor device 32t, which is used to detect whether the latch 22 in the lock case 30a of the passive wing lock device is retracted or extended or is being retracted or extended. The case-lifting device 31 has as in the Figures 6a and 6b and even better in the Figures 7a to 7d a latch operating slide 31a can be seen, which is guided horizontally with its plate-shaped base body in the linear guide device 31b fixed in the lock case. In addition, a sensor plate 31tp is displaceably guided in the linear guide device 31b. The sensor plate 31tp has two contact plates on its front end edge, which come into contact with the latch 11 . The sensor plate 31tp is acted upon outwards by a spring, in the case shown a torsion spring. The spring is dimensioned in such a way that when the latch 11 is retracted, it is over-pressed and the latch takes the sensor plate 31tp into abutment with the contact plates. The sensor plate 31tp has at its in the Figures 6a and 6b lower edge region has a lateral actuating edge which interacts with the obliquely angled actuating edge of a plate-shaped detection element 31te which is movably mounted in a receptacle which is fixed in the lock case. The detection element 31te has an extension which engages in a light sensor 31s arranged in the lock housing 1a when the sensor plate 31tp moves into the lock housing 30a. The retraction and extension of the latch 11 can thus be detected by the sensor device 31t.

The task and objective of the sensor device 31t is as follows:
The sensor device 31t has two functions for the lifting process. One function is to ensure that the latch 11 is fully extended out of the lock housing 30a of the passive lock device when retracting, so that the latch 11 cannot impede the opening of the door. The other possible function is to ensure that the latch operating slide 31a is not extended too far out of the lock housing 30a when the latch is retracted and to ensure that the latch operating slide 31a thus does not impede the opening and closing of the door. In order to prevent such an obstruction of the door, provision can also be made for the sensor slide to have an entry and/or exit slope on its front face. The sensor device 31t controls a control device, not shown, of the lifting device 31. The control device is controlled via electrical signals which the sensor device 31t emits when the trap is detected and which are fed to the control device.

Another possible function of the sensor device 31t is that z. B. can be monitored via a control center whether the double-leaf door is closed and locked. As far as locking monitoring is concerned, this applies to exemplary embodiments in which the latch is designed as a latch bolt and to exemplary embodiments in which a corresponding sensor device is additionally or alternatively provided in the area of the bolt lifting device 32 .

In the exemplary embodiments illustrated in the figures, the sensor device 31t is provided only in the case-lifting device 31 . The bolt-lifting device 32 in the exemplary embodiments of the figures provides for the spring loading of the bolt-actuating pressure piece 32c and the prism-shaped design of the bolt-actuating pressure piece 32c for proper functioning. The spring loading ensures that the bolt is fully retracted into the lock case 1a of the active wing lock device, in which position it then locks in the lock housing 1a d. H. self-determined is kept. The spring loading in connection with the prism shape of the pressure piece then allows the double-leaf door to be opened and closed without the leaves interfering with each other when opening and closing in the area of the closed position, even with a large tolerance range with a gap between the two leaves in the closed position of the door.

figure 12 shows a non-inventive embodiment of the passive wing lock device with a sensor device 31s, compared to the sensor device 31t of the embodiment of FIG Figures 7a to 7f is modified. Just like the embodiment of Figures 7a to 7f serves the sensor device 31s figure 12 for detecting whether the latch 22 in the lock case 30a of the passive wing lock device is retracted or extended or is currently being retracted or extended. The sensor device 31s is composed of a light sensor 31se and a sensor button 31st. The light sensor 31se is an optical sensor. It has a U-shaped receptacle into which the free end of the sensor button 31st engages. In contrast to the embodiment of Figures 7a to 7f is in the exemplary embodiment figure 12 the sensor button is not designed as a slide, but as a two-armed lever. The sensor button 31st in figure 12 interacts directly with the light sensor 31se. In the embodiment of Figures 7a to 7f is provided between the light sensor 31s and the button 31tp and a wedge-shaped transmission member 31te.

The sensor button 31st of the sensor device in figure 12 is designed as a feeler lever, which is mounted in the lock case so that it can pivot about an axis 31sta that is fixed to the lock case. The feeler lever 31st is designed as a two-armed lever. The first lever arm 31stt is used here for pressing the lock latch 11 of the active wing lock device. The second lever arm 31sts has a hook-like extension that protrudes into the U-shaped receptacle of the light sensor 31s. The first lever arm 31stt of the feeler lever 31st protrudes into the predetermined space of the passive wing lock, which is provided for receiving the latch 11 of the active wing lock. Next is an in figure 12 spring, not shown, is provided, which acts on the feeler lever 31st in the outward direction.

The sensor device according to figure 12 works as follows: When the door is in the closed position, the latch 11 of the active lock device is spring-loaded into the space of the passive wing lock device provided to accommodate the latch 11 . The latch 11 comes into contact with the first lever arm 31stt of the feeler lever 31st, so that the feeler lever 31st is pivoted about its axis of rotation 31sta by the latch 11 entering the passive wing lock device. The hook-like extension of the sensing lever 31st, which protrudes into the light sensor 31s when the door leaf is open, has left the U-shaped receptacle of the light sensor 31se when the latch 11 has reached its closed position. Depending on whether it is actuated or not, the light sensor 31se emits corresponding electrical signals which are processed by an electrical signal processing system.

In modified versions, the interaction of the sensing lever 31st and the light sensor 32se can also be provided such that the sensing lever 31st engages in the light sensor 31se when the latch 11 is retracted into the receiving space of the passive leaf lock case. When the sash is open, the hook-like extension of the feeler lever 31st is then outside the receptacle of the light sensor 31. In this modified version, too, the light sensor 31se emits corresponding electrical signals, depending on whether it is actuated or not, which are processed by an electrical signal processing system.

figure 13 shows an exemplary embodiment of the passive wing lock device with two further sensor devices 32s and 37s, one of which is assigned to the bolt 22 and the other to the lock follower 37.

The sensor device 32t is used to detect whether the bolt 22 in the lock case 30a of the passive wing lock device is moved in or out or is just being moved in or out. This sensor device 32t is constructed analogously to the sensor device 31t figure 12 , which detects the position of the trap. The sensor device consists of a light sensor 31se and a sensor button 31st. The sensor button 31st is also designed as a two-armed lever which is mounted in the lock case so that it can pivot about an axis 31sta. The sensor button 31st has a first lever arm 31stt, which is used to feel the bolt 22, and a second lever arm 31sts on, which interacts with the light sensor 31 se.

The sensor device 37s serves to detect an actuation of the lock follower 37 . A light sensor 37se is provided for this purpose. The lock follower 37 has a radially protruding arm 37fs, which is provided with an extension designed as an angled edge. In the rest position of the passive wing lock device, the extension 37fs protrudes into the U-shaped receiving area of the light sensor 37se. If the operating handle on the passive wing lock is actuated by a user, the lock follower 37 is turned. The edge-like extension 37fs of the lock follower 37 then leaves the receiving area of the electric light sensor 37se. The light sensor 37se then emits a corresponding electrical signal which can be processed by electrical signal processing equipment. The sensor device 37s can be used to detect whether the passive wing lock was opened by manual actuation of a handle or push rod arranged on the passive wing.

In figure 14 a sensor device 36s not according to the invention is shown, which is used to detect a movement of the transmission slide 36. A light sensor 36se is provided for this purpose. The gear slide 36 has a protruding extension 37fs. In the rest position of the passive wing lock device, as in figure 14 shown, the extension 37f is located outside the U-shaped receiving area of the light sensor 37se. If the passive wing lock is actuated by a user using the actuating handle or by the motorized actuating device, the gear slide 36 is pushed upwards. Here, the extension 36fs of the gear slide 36 enters the receiving area of the electric light sensor 36se. The light sensor 36se then emits a corresponding electrical signal which can be processed by electrical signal processing equipment. The sensor device 37t can be used to detect whether the passive wing lock was opened by manual actuation of a handle or push rod arranged on the passive wing.

The sensors 31se, 32se, 36se and 37se are mounted on a circuit board that is mounted in the lock case. In addition, an electronic device is provided for evaluating and/or further processing the data from the sensors. This electronic device can be arranged in a separate housing. This separate housing can be arranged adjacent to the lock case, preferably coupled.

The circuit board on which the sensors are arranged is electrically connected to the electronic device. For example, electrical cable connections can be provided for this purpose, via which the circuit board is connected to the electronic device arranged in the separate housing. With the help of the information from the sensors 31s and 32s, for example, a control center can monitor in a public building whether a double-leaf door is open or in the closed position or locked. Furthermore, a monitoring center can determine whether a door was unlocked by actuating the follower or by activating the motorized actuating device. When the lock device is unlocked using the motorized actuating device, the position of the lock nut remains unchanged and the signal from the sensor 37s also remains unchanged, while unlocking by actuating the handle causes the lock nut 37 to rotate and is detected by the sensor 37s assigned to the nut.

The sensors can also be used to control the motorized actuation device when the lock device is unlocked. The sensors 31se and 32se can be used to detect during unlocking whether the latch 11 or the bolt 22 no longer protrudes into the associated receptacles of the passive wing lock, whereupon the motorized actuating device can be deactivated.

Actuation of the passive leaf lock device

The passive wing lock device 30 can be actuated via a manual actuation device, which is not shown in the figures. The manual actuating device can be designed as a rotary handle that can be inserted into the lock follower 37, the lock follower 37 representing a part of the lock mechanism. The rotary handle can be designed as a conventional pusher or as a push bar, a so-called panic push bar. Both the handle and the push rod can have a corresponding rotating connection, which can be plugged into the lock follower 37 in a rotationally fixed manner for coupling to the lock gear.

By actuating the actuating device, the lock follower 37 is rotated and the lock mechanism is thereby actuated. When the lock gear is actuated, the gear slide is moved. When the lock mechanism is actuated, the locking rod connecting devices 38o, 38u are displaced vertically in opposite directions, depending on the direction of rotation of the actuation. In addition, when the lock mechanism is actuated, the latch lifting device 31 and the bolt lifting device 32 are also actuated simultaneously or with a time delay.

The lock mechanism is designed in such a way that an actuation of the lock follower 37 in one direction moves the upper locking rod connection device 38o upwards and the lower locking rod connection device 38u downwards, and consequently the relevant locking rods 380o and 380u are each extended, i.e. moved into their locking position will. The lifting devices 31, 32 for lifting the latch 11 and the bolt 12 are actuated via the lock gear in such a way that the latch actuating slide 31a and the bolt actuating slide 32a are retracted into the lock housing 30a of the passive lock device 30. If the If the lock follower 37 is rotated in the opposite direction by actuation, the locking rod connection devices 38o, 38u move in the opposite direction, as a result of which the locking rods 380o, 380u are retracted, i.e. the locking rods are unlocked and the lifting devices 31 and 32 are extended to release the bolt 22 and retract the case 11 of the active lock device into the lock case of the active lock device.

Instead of the manual actuating device, a corresponding motorized actuating device with rotary output can also be coupled to the lock follower 37 . The lock follower 37 is rotated in a corresponding manner by this motorized actuating device and the lock gear is actuated, so that the two locking bar connection devices 38o, 38u and the lifting devices 31, 32 are actuated in the same way.

A motorized actuating device can also be used, which, in contrast to this, has a linear output. The linear output can be coupled directly to the gear slide 36 . The actuation of the lock gear by the linear output of the motorized actuation device then acts in the same way as when the lock gear is actuated by rotating the lock follower 37, as described above.

the Figures 5a and 5b show a non-inventive passive leaf lock device 30 with such a motorized actuating device 37m arranged at the lower end of the lock case 30a. The motorized actuating device 37m is coupled to the lock mechanism via a coupling slide 37k, which is coupled with one end to the linear output of the motorized actuating device 37m and with its other end to the geared slide 36 of the lock mechanism so that it cannot move.

Figures 5c and 5d show the clutch slide 37k coupled to the transmission slide, without the motorized actuating device 37m being coupled. The configuration with the motorized actuation device can be optional.

The anti-tamper devices

Different manipulation protection devices are provided in the exemplary embodiments illustrated in the figures. The manipulation protection devices are intended to prevent the locking rods from being able to be retracted as a result of pressure being applied to the locking rod 380o and/or 380u from the outside.

A non-inventive embodiment of such

Anti-tamper device is in the Figures 4a, 4b and 4c shown. Here a blocking member 39b is movably mounted in the lock housing 30a and blocks displacement of the locking bar in the retraction direction when external pressure is applied, in that the blocking member 39b engages in a recess 36a in the gear slide 36 in its blocking position. Figure 4a shows the position before a manipulation attempt is made by external pressure being applied to the locking rods 380o, 380u.

Figure 4b shows the blocking member 39b in the blocking position during an attempt at manipulation. The gear slide 36 is manipulated by applying pressure to the locking bars from the position in Figure 4a moved up a little and is held against further upward displacement by the blocking member 39b.

Figure 4c shows the blocking member 39b in the release position, in which it is disengaged from the gear slide 36. The blocking member 39b is shifted into this release position by the actuation of the lock nut 37 in that, by rotating the lock nut 37 counterclockwise in the illustration in the figure, the driver 37a fixed to the lock nut 37 interacts with the blocking member 39b and the blocking member 39b in the representation in the Figure 4c shifted to the left.

This first embodiment of the anti-tamper device in the Figures 4a to 4c thus acts on the gear slide 36 and thus on both locking bars; however, it requires an actuating device on the lock follower 37. An inventive design of a tamper protection device is in the Figures 9a and 9b shown. This anti-tampering device does not require actuation of the lock mechanism via the lock follower 37, but the actuation of the lock mechanism can also be carried out via a linear output of the geared slide, for example via the motorized actuating device 37m Figures 5a and 5b take place. This version of the anti-tamper device looks in the embodiment of Figures 9a and 9b a connecting link device 39k, which is formed between the upper locking rod connection device 38o and the gear slide 36. The link device 39k has a link slot 39ok, which is formed with the plate-shaped main body of the upper locking rod connection device 38o. The link device 39k also has a lever 39h, which is mounted in a pivot bearing fixed to the lock case and has a link pin at one end, which engages in the link slot 39ok and at its other end has a guide pin, which engages in a slot in the gear slide 36 is formed.

Link slot 39ok is formed as an angled slot with an upper vertical branch and a lower horizontal branch. In the event of an attempt at manipulation, the link pin 39s moves into the upper vertical branch of link slot 39ok and blocks vertical movement of upper locking rod connection device 38o (see Figure 9a ). As a result, no manipulation movement is transmitted to the gear slide 36 .

In the event that there is no attempt at manipulation, i.e. no pressure is applied to the upper locking bar 380o from the outside, the arrangement of the lever 39h, which can be correspondingly spring-loaded, is such that the link pin 39s enters the horizontal branch of the link slot 39ok. By actuating the lock gear, i.e. by actuating the gear slide 36, the upper locking rod connecting device 38o and thus the upper locking rod 380o can now be actuated, i.e. extended and retracted.

The link device 39k described above thus forms the above-described embodiment of the invention Figures 9a and 9b an anti-tamper device for the top latch bar 380o.

For the lower locking bar 380u, which in the embodiment in question is moved in the same direction as the gear slide 36 of the lock gear, a manipulation protection device is provided, as is shown in FIGS Figures 10a and 10b is shown. This manipulation protection device has a blocking lever 39p, which is mounted in a pivot bearing fixed to the lock case. He is gravity fed into the in Figure 10a with its free end pointing to the left. In this position, a blocking pin 39s fixed in motion with the gear slide 36 engages in the hook-shaped recess of the blocking lever 39p. If the gear slide 36 is moved upwards for unlocking by actuating the lock gear, there is a relative displacement between the blocking pin 39s and the blocking lever 39p, during which the blocking pin 39s slides up the curved edge of the blocking lever 39p and the blocking lever 39p in the illustration in Figure 10a counterclockwise (see Figure 10b ). If the gear slide 36 is now moved downwards in the opposite direction by actuating the lock gear via the actuating device, the reverse relative movement takes place back into the position in Figure 10a .

Figure 10c shows the situation in the event of a manipulation attempt. The plate-shaped base body of the lower locking rod connection device 38u is guided upwards in the elongated holes by the pressure exerted on the locking rod 380u and comes into contact with the lower base of the blocking lever 39p. In this way, displacement of the lower locking bar 380u in an attempt at manipulation is counteracted and the lower locking bar 380u is blocked in the extended position. The vertical movement of the lower bolt connection device 38a is thus not transmitted to the gear slide 36.

figure 11 shows a non-inventive embodiment of the passive wing lock device with a manipulation protection device for the lower locking bar 380u, wherein the manipulation protection device according to figure 11 against the anti-tamper device according to Figures 10a to 10c is modified. The tamper protection device has a blocking lever 39p, which is mounted in a pivot bearing fixed to the lock case. The blocking lever has a blocking stop 39b which, in the blocking position, interacts with the lower locking rod connecting device 38u, as shown in FIG figure 11 is shown. The blocking stop 39b is formed as a stop step of the side edge of the blocking lever 39p. The manipulation attempt is in figure 11 shown. figure 11 shows the protection against tampering in the event of a tampering attempt. The protection against tampering consists in the fact that when pressure is exerted on the lower locking rod connection device 38u, the lower locking rod connection device 38u comes into the stop position on the blocking stop 39b of the blocking lever 39p and is thus blocked against further displacement in the vertical direction upwards. As a result, no vertical movement is transmitted to the gear slide 36 through the lower locking rod connecting device 38u.

The blocking lever 39p is provided with a link slot into which a link pin 36k of the gear slide 36 engages. If, in the case of a proper unlocking by actuating the nut 37 or the motorized actuating device 37m, the gear slide 36 is pushed upwards for unlocking, the pin 36k fixed to the gear slide moves vertically upwards and runs in the link slot 39k of the blocking lever, whereby the blocking lever 39p is pivoted counterclockwise in the case shown. When pivoted, the blocking lever 39p then no longer protrudes in a blocking manner into the range of motion of the lower locking rod connection device 38u. Simultaneously with the pivoting of the locking lever 39p, a lever 38h is pivoted. The lever 38h is mounted in the lock case 38a such that it can pivot about an axis 38a fixed to the lock case and interacts with an actuating stop arranged on the gear slide 36 at the foot end. When pushing up the gear slide 36, the lever 38 is pivoted clockwise in the case shown. The lever 38h is designed as an actuating lever for the lower locking rod connection device 38u. Its free end interacts with a corresponding stop on the lower locking rod connection device 38u. The lower locking rod connecting device 38u is thus moved in the same direction as the gear slide 36 and the lower locking rod is retracted into the lock case.
