Description

[0001] The invention relates to a lock for a door according to the features of the preamble of claim 1.

[0002] Such a lock is known, for example, from EP 2 924 201 A1. The described lock comprises a motor and various sensors for detecting the positions of individual components of the lock mechanism. The lock is designed as a mortise lock and has a lock housing with a forend. The lock components are protected within the lock housing. To control the motor and sensors, the lock must be connected via a cable.

[0003] Furthermore, a mortise lock with several sensors is also known from DE 20 2012 009 652 U1.

[0004] In practice, such locks are used to enable electronic monitoring and / or detection of locking states and / or the proper functioning of locks. As the number of electronic components increases, the cabling effort increases significantly. Furthermore, it is difficult to retrofit corresponding sensor locks into existing systems, as the existing on-site cabling is often limited and laying new cabling is very costly.

[0005] The present invention is based on the object of creating a lock for a door that comprises a plurality of electronic components and is easy to install. In particular, the lock should be easy to retrofit. Preferably, the costs for manufacturing and installing the lock should be kept as low as possible.

[0006] This object is achieved according to the invention by a lock having the features of claim 1 and by a lock according to the features of claim 3.

[0007] According to the invention, a lock for a door is proposed, in particular a mortise lock, with a lock housing for receiving lock components, a faceplate connected to the lock housing and at least one locking element for locking a door and a lock nut rotatably mounted in the lock housing for actuating the at least one locking element, wherein an integer number S of sensors is arranged in the lock housing.What is important here is that the lock has an interface with a number A of connection poles to which a multi-core cable can be connected in order to connect the lock to a control panel and / or a power supply, wherein the number A of connection poles is smaller than the number S of sensors, or that in the case of a power supply via the connection poles, the number A of connection poles minus 2 power connection poles is smaller than the number S of sensors, and that a selector switch is arranged in or on the lock housing by means of which it is possible to set which of the sensors from the number S are connected to the connection poles.

[0008] Advantageously, the lock allows for a large number of sensors without the corresponding cabling effort increasing with the number of sensors. InPractice has shown that not all of the sensors present in a lock are needed for monitoring in each application, but only a selection. According to the invention, a selection, in particular a subset, can be selected from the set S of sensors using the selector switch, which are connected to the connection poles of the lock interface. Different subsets can be selected using multiple switching positions of the selector switch. This means that not all of the sensors have to be wired or connected externally, but only those that are actually required for a monitoring task. This has the effect of significantly reducing the effort required for the wiring or the interface. Another advantage is that a multi-core cable can be used which has a relatively small number of cores, in any case fewer than the number S of sensors present in the lock.This reduces both the cabling effort and the costs, as a more cost-effective cable can be used which is easier to install and distribute.

[0009] For example, the lock can be configured to comprise a set S of 12 sensors. The number A of connection poles of the interface is smaller than the set S. For example, it can be A=8. Using the selector switch, a subset can be selected from the set S of sensors and switched to the number A = 8 of connection poles. Of course, the number of connection poles can vary accordingly, for example, in the range between A=3 connection poles and A=10 connection poles. Depending on the position of the selector switch, a different sub-combination of sensors can be selected and switched to the connection poles A of the interface. This allows for flexible use of the lock.

[0010] For this purpose, a selector switch with multiple switching positions can be selected. For example, a rotary switch with 10 or 15 different detent positions can be used to connect 10 or 15 different subsets of sensors to the connection terminals of the interface.

[0011] Of course, the number of connection poles (set A) can be varied. Likewise, the number of sensors (set S) in the lock can be varied. The basic idea of ​​the invention is that the number A of connection poles is smaller than the number S of sensors in the lock, so that a corresponding selection can be made via the selector switch, thus reducing the necessary installation effort.

[0012] In particular, the lock can be provided with a control device, in particular with a microprocessor connected to the interface for detecting the sensor signals. Preferably, the sensor signals can be connected directly to the connection terminals. This means that the sensor signals are transmitted directly via the connection cable and can be read and detected by a higher-level control center.

[0013] Alternatively, the lock can also be interfaced with a microprocessor. The microprocessor can evaluate or detect the sensor signals and output a corresponding signal via the connection terminals. This allows for greater immunity to interference, as any interference signals present via the cable are not affected by the sensor evaluation directly in the lock.

[0014] The inventive concept also comprises a lock for a door, in particular a mortise lock, preferably according to one of the preceding embodiments, with a lock housing for receiving lock components, a faceplate connected to the lock housing, and at least one locking element for locking a door and a lock nut rotatably mounted in the lock housing for manually actuating the at least one locking element, wherein a control device is arranged in the lock housing and an integer number S of sensors is arranged, and / or an electromechanical actuator or motor is arranged.It is essential that the lock has an interface connected to the control device, to which a multi-core cable and / or bus cable can be connected in order to connect the lock to a control center and / or a power supply, and that the interface is designed as a switchable interface which can be switched between digital bus operation and discrete operation by means of a switch, wherein the switch is arranged in or on the lock housing in order to switch the interface either to digital bus operation for connecting a serial data bus, or to discrete operation for connecting a multi-core cable.

[0015] A particular advantage is that the lock's connection type can be switched between digital bus operation and discrete operation. This allows the lock to be integrated into existing systems that already have a bus system, as well as into existing systems that require conventional discrete cabling. This further expands the lock's application range.

[0016] In particular, it can be provided that the lock has a selector switch by means of which it can be set which selection of sensors from the set S can be switched via the interface to a respective core of the multi-core cable or to a connection pole, and has a changeover switch to switch the interface between digital bus operation and discrete operation. The combination of the selector switch with the changeover switch can enable particularly flexible use of the lock. For example, in discrete operation, the selector switch sets which selection of sensors, i.e. which subset of sensors, from the set S are routed via the interface to the multi-core cable. In the case of digital operation of the interface, i.e. when a digital data bus is connected, the type of data bus can be set via the selector switch, so that the lock can be operated optionally on different bus types.For example, it is conceivable to operate the lock on a CAN bus, a Hi-O bus, a LON bus or an ASi bus, or similar.

[0017] In particular, it is provided that in the case of bus operation of the interface, the type of connectable data bus can be set via the selector switch.

[0018] In one embodiment, the selector switch can be designed as a multi-stage switch, in particular as a multi-stage rotary switch or as a multi-stage latching switch. For example, an alphanumeric rotary switch can be used as the selector switch. A latching switch with multiple latching positions, for example, 5, 6, or 7 latching positions, can also be used as the selector switch.

[0019] Alternatively or additionally, the selector switch can be designed as a multi-stage DIP switch, in particular as a three-stage, four-stage, or five-stage DIP switch. Different binary combinations can be set via the DIP switches, allowing a wide range of sensor selections and thus enabling a correspondingly flexible application of the lock.

[0020] Advantageously, the selector switch and / or the changeover switch can be accessible from outside the lock housing. This allows the selector switch to be easily operated during lock installation, eliminating the need to open the lock to adjust the sensors. Similarly, the changeover switch can also be accessible from outside the lock housing. This allows the lock to be switched between bus operation and discrete operation by flipping the changeover switch without opening the lock housing from the outside.

[0021] In particular, the multi-core cable can be a three-core cable, a four-core cable, a five-core cable, a six-core cable, or a seven-core cable. Of course, the expert can also use cables with more than seven cores, depending on the specific application.

[0022] To enable particularly flexible use, at least one connection pole, several of the connection poles, or all of the connection poles can be configured as input or output, and a selector switch can be used to select whether or which of the connection poles is configured as input or output. By allowing a selector switch to configure some of the connection poles as inputs, it is possible to use the lock not only to query sensors but also to control electromechanical actuators and / or motors.

[0023] In particular, it can be provided that the control device has a microprocessor for detecting sensor signals, and one of the connection pins is connected to an input or an output of the microprocessor. For example, the I / O ports of the microprocessor can be connected to the connection pins, so that the multi-core cable can be connected directly to the microprocessor via the connection pins.

[0024] In particular, the lock housing can be a mortise lock housing, and the selector switch and / or changeover switch can be arranged on a side wall or rear wall of the lock housing in such a way that it is no longer accessible when the lock housing is installed in a lock pocket of a door. This allows for convenient adjustment of the selector switch and / or changeover switch during installation. Once the lock is installed in the door, the selector switch and the changeover switch are concealed within the door leaf and are no longer accessible from the outside. This prevents subsequent tampering with the lock setting.

[0025] In one embodiment, the control device can be connected to the selector switch and the sensors and has an assignment matrix to connect a specific sensor combination or selection of sensors from the set S to the multi-core cable according to the different selector switch positions. The assignment matrix can, for example, be mapped in the memory of the microprocessor of the control device and linked as a table according to a selected switch position of the selector switch.

[0026] In a preferred embodiment, it can be provided that the lock is designed as an active wing lock, in particular as a panic lock, and has a lock bolt, in particular a self-locking one, and a lock latch as locking elements.

[0027] In particular, the lock can be designed as a motor lock and have a motor drive for locking or unlocking.

[0028] Preferably, it can be provided that the motor drive is supplied with power via the interface and that, depending on the position of the changeover switch, the motor drive is controlled via a data bus or via a multi-core cable.

[0029] In a preferred embodiment, it can also be provided that the lock is designed as a shoot bolt lock for a passive leaf of a double-leaf door and has, as locking elements, an upper retraction slide for connecting an upper shoot bolt rod and a lower retraction slide for connecting a lower shoot bolt rod, wherein the two retraction slides are connected by means of a pivotally mounted bell crank which can be actuated by means of a motor or manually by means of a lock nut in order to retract or extend the retraction slides with the shoot bolt rods, and that the interface has a control device connected to the motor and both the motor and the control device are supplied with electrical energy and control signals via the interface.

[0030] In one embodiment, it can be provided that a spring drive is provided and the locking elements are retracted by motor or manually operated by the lock nut while charging the spring drive and are extended with the support of the spring drive when extended.

[0031] The inventive concept also includes a locking device for a double-leaf door comprising a fixed leaf and a moving leaf, wherein the fixed leaf has a lock designed as a shoot bolt lock according to one of the embodiments described herein, and / or the moving leaf has a lock designed as a panic lock according to one of the embodiments described herein, and wherein the shoot bolt lock has a bolt ejector and / or a latch ejector in order to unlock a bolt and / or a latch of the panic lock.

[0032] The lock according to the invention is particularly intended for use in building doors. The lock can be used for both single-leaf and double-leaf building doors. The lock according to the invention can be used in the design of new building security solutions and can also be easily retrofitted into existing projects.

[0033] Further embodiments and examples of the espagnolette lock according to the invention are shown in the figures and described below. They show: Fig. 1: the lock according to the invention on a double-leaf door; Fig. 2: a schematic representation of a lock according to the invention; Fig. 3: a schematic cable diagram in direct mode; Fig. 4: a schematic cable diagram in bus mode; Fig. 5: an application example locked as a deadbolt lock; Fig. 6: the deadbolt lock according to Fig. 5Motor-unlocked; Fig. 7: the cut-out slide plate of the espagnolette lock; Fig. 8: the connection of the reversing lever to the lower retracting slide; Fig. 9: the connection of the reversing lever to the upper retracting slide; Fig. 10: the espagnolette lock in a manually unlocked position; Fig. 11: the connection of the nut lever to the lower retracting slide; Fig. 12: a schematic representation of the interaction between the bolt slide and the latch reversing lever; Fig. 13: latch ejector with latch reversing lever.

[0034] The figures show exemplary embodiments of the lock 2, 16 according to the invention. These are not intended to be limiting. In the figures, components with equivalent functions are provided with the same reference symbols. A person skilled in the art can combine the various embodiments shown with one another, based on their technical skills, within the scope of protection defined by the claims, without departing from the spirit of the invention.

[0035] The Fig. 1 shows a schematic representation of a locking device 1 on a double-leaf door 11. The double-leaf door 11 has a fixed leaf 14 and a moving leaf 15. The fixed leaf 14 is pivotally mounted on a door frame 12 of the double-leaf door 11 via hinges 131, 132. Likewise, the moving leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via hinges 133, 134.

[0036] The active leaf 15 has, as an example of the lock according to the invention, a panic lock 16, which is actuated via a door handle 17. The panic lock 16 is designed as a self-locking panic lock and has an automatically extending bolt and a latch. The panic lock 16 is connected to a higher-level control center by means of a multi-core cable 18a and a flexible cable transition 19a. Via a control device 7 integrated in the lock housing, which is Figures 3 and 4 shown, the connection to cable 18a can be adjusted accordingly.

[0037] In the inactive leaf 14, a drive bolt lock 2 is shown as an example of the lock according to the invention. The drive bolt lock 2 has an upper drive bolt bar 24 and a lower drive bolt bar 25. In the illustration of the Fig. 1the espagnolette lock 2 is locked, ie the two espagnolette rods 24 and 25 are extended and lock the inactive leaf 14 to the door frame 12 and the floor. The espagnolette lock 2 can be manually unlocked via a lock nut 23. Furthermore, the espagnolette lock 2 has a motor, by means of which the espagnolette lock 2 can be unlocked by motor. The connecting cable 18 of the motor 3 or the control device 7 of the motor 3 is guided through the inactive leaf 14 and via a flexible cable transition 19 over the door frame 12. Via the control device 7 integrated in the lock housing 21, which is in the Figures 3 and 4 shown in more detail, the connection to the cable 18 can be adjusted accordingly.

[0038] The espagnolette lock 2 has a latch receiving space and a bolt receiving space, into which the locking elements of the panic lock 16, i.e., the latch and the bolt, can engage. The panic lock 16 can be unlocked by means of the espagnolette lock 2 via the latch slide or bolt slide. This means that when the espagnolette lock 2 is unlocked, the panic lock 16 is unlocked first, so that the active leaf 15 can be opened, while the inactive leaf 14 is still locked via the espagnolette bars. Only when the espagnolette lock 2 is completely unlocked can the inactive leaf 14 also be opened.

[0039] In the Fig. 2A lock according to the invention is shown schematically. The lock 2 is shown ready for installation. It has a lock housing 21 with a forend 22. A rotatable lock nut 23 is accommodated in the lock housing 21 for manually operating the lock. A drive motor 3 is also accommodated in the lock housing 21 for motor-operated operation of the lock 2.

[0040] Furthermore, the lock 2 comprises in its lock housing 21 a plurality of sensors which are connected from outside the lock housing 21 as shown in Fig. 2are not visible in the illustration. A changeover switch 83 is arranged on the rear of the lock housing 21. The changeover switch 83 is designed as a latching switch and can be switched between positions B for bus operation and D for direct or discrete operation. A selector switch 84, designed as a four-pole DIP switch, is arranged in the area of ​​the rear of the side wall. In the case of direct operation, the selector switch 84 can be used to select a number of sensors as a subset of the total number S of sensors present in the lock, which are led to the outside via the connecting cable 18.

[0041] The connecting cable 18 is connected to a control device 7 of the lock 2 via an interface 82, as can be seen from the schematic cable diagrams of the Figures 3 and 4 is evident.

[0042] The control device 7 has a microprocessor 81. A plurality of sensors are connected to the control device 7. In the one in the Figures 3 and 4In the exemplary embodiment shown, there is a latch contact 42, a bolt contact 51, a locking sensor 71, a center position sensor 72, an unlocking sensor 73, a bolt retraction sensor 74, a latch ejector sensor 75, a follower sensor 76, a top or bottom locking sensor 77, a bolt ejector sensor 78, and a tamper sensor 79. This means that a total of 11 sensors are arranged in the lock 2, so that the number S of sensors is S = 12. The interface 82 has 7 connection poles, so that the number of connection poles is A = 7. In the exemplary embodiment shown, the power supply is conducted via the connection poles, i.e. 2 of the 7 connection poles are required for the power supply and are not available for input or output signals. This means that the number of poles that can be switched as input or output via the selector switch 84 is 5.

[0043] In addition, a motor drive 3 is connected to the control device 7. For example, the control device 7 can have a power stage for controlling the motor 3. The motor 3 is also controlled via the control device 7 or the microprocessor 81. The control signals required for the motor 3 are also routed via the interface 82 or one or more connection poles of the interface 82. The assignment of the connection poles of the interface 82 can be set accordingly via the selector switch 84. Depending on the combinations of the 16 possible combinations set on the selector switch 84, which is designed as a four-pole DIP switch, one connection pole is designed as an input for controlling the motor 3, and the other connection poles are connected as outputs for sensor signals.Depending on the combination set on the selector switch, a different subset of sensors from the total number of sensors S is connected to the outside via the connection terminals. The specialist selects the appropriate subset according to the required application. These signals are routed to a higher-level control center via the connecting cable 18, which has seven wires (shown in the example). The connecting cable 18 can also have more or fewer wires.

[0044] By means of the switch 83, the operation of the interface 82 or the control device 7 can be switched between bus mode and direct mode. In the representation of the Fig. 3 The switch 83 is in position D, i.e. direct mode. This means that the interface 82 is operated in direct mode and is designed for discrete cabling. In the illustration of the Fig. 4In contrast, switch 83 is in position B, i.e., bus mode. This means that interface 82 is operated in digital mode as a bus interface.

[0045] For example, as in the example of Fig. 4 As shown, a four-pin connecting cable 18 is used as the bus cable. The power supply with plus and minus is carried via the connecting cable 18. In addition, a serial data bus can be routed via two wires, for example a CAN bus, so that one wire carries the CAN high signal and one wire the CAN low signal. The selector switch 84 can be used according to the Fig. 4 It can be set whether a CAN bus, a Hi-O bus, a LON bus or an ASi bus can be connected to interface 82.

[0046] In the Fig. 5As an example of a lock according to the invention, a drive bolt lock 2 is schematically shown in the locked position. The drive bolt lock 2 has a lock housing 21, on the front of which a face plate 22 is arranged. The components of the drive bolt lock 2 are accommodated within the lock housing 21. For clarity, Fig. 2 The lock cover is removed or shown transparently. The espagnolette lock 2 has an upper espagnolette bar 24 and a lower espagnolette bar 25. The espagnolette bars are each connected to the mechanism of the espagnolette lock 2 via retraction slides 241 and 251. The upper retraction slide 241 is connected to the upper espagnolette bar 24. The lower retraction slide 251 is connected to the lower espagnolette bar 25.

[0047] Furthermore, the espagnolette lock 2 comprises a bolt ejector 5 and a latch ejector 4. In the Fig. 5In the locked position shown, the espagnolette bars 24, 25 are extended upwards or downwards out of the lock housing 21 to the maximum extent for locking a passive leaf 14. The latch ejector 4, as well as the bolt ejector 5, is retracted into the lock housing 21. This creates a receiving space in front of the latch ejector 4 and the bolt ejector 5, into which a latch or a bolt of an active leaf lock can engage. This allows the espagnolette lock 2 to be locked not only via the espagnolette bars 24, 25, but also via the locking elements of an active leaf lock.

[0048] Furthermore, the espagnolette lock 2 comprises a motor drive comprising an electric drive motor 3 with a motor output 31, which is designed as a spindle drive. The motor output 31 comprises a spindle 32 and a spindle nut 33. The spindle nut has two stop surfaces 331 and 332, each of which interacts with a pin of a slide plate 27. The slide plate 27 is mounted in the lock housing 21 parallel to the forend 22 for linear displacement and can be actuated by the motor 3 or the spindle drive 31. In the locked position shown, the slide plate 27 is arranged in its lower position. The spindle nut 33 is also arranged in the lower position.

[0049] Furthermore, the espagnolette lock 2 comprises a spring drive 6 comprising two compression springs 61 and 62. The spring drive 6 is charged when the espagnolette lock is unlocked. When locked, the spring drive 6 acts as a support to move the espagnolette lock 2 into the locked position.

[0050] Furthermore, the espagnolette lock 2 has a lock nut 23, via which the espagnolette lock 2 can be unlocked manually or mechanically. The lock nut 23 is connected in a rotationally fixed manner to a nut lever 231. The nut lever 231 has a driver 232 on its upper side for actuating or driving a bolt slide lever 28.

[0051] The bolt slide lever 28 is rotatably mounted concentrically to the lock nut 23 and has two interconnected bolt slide arms. The first bolt slide arm 281 is arranged above the lock nut 23 and the second bolt slide arm 282 is arranged below the lock nut 23. The upper bolt slide arm 281 interacts with the latch slide 4 via a latch deflection lever 41. The lower bolt slide arm 282 interacts with the bolt ejector 5. When the bolt slide lever 28 is rotated counterclockwise, both the bolt ejector 5 and the latch ejector 4 are actuated into the unlocked position, i.e. moved towards the face plate 22. This allows locking elements of an active sash lock (not shown) that engage in the lock housing 21 of the shoot bolt lock 2 to be displaced from the latter into an unlocked position.

[0052] The two feed slides 241, 251 are connected to each other via a reversing lever 26. As can be seen from Fig. 8 As can be seen, the lower feed slide 251 is rotatably connected to the reversing lever 26 via the engagement point 254, which is designed as a pivot pin. The reversing lever 26 is designed as a two-armed reversing lever. The engagement point 254 is arranged on the first arm 261 of the reversing lever 26, and a guide pin 265 is provided on the second arm 262 of the reversing lever 26 in order to connect the reversing lever 26 to the first feed slide or the upper feed slide 241 ( Fig. 9 ).

[0053] As well as from Fig. 11 As can be seen, the nut lever 231 has a roller 233 at its end, which interacts with the lower retraction slide 251. When the lock nut 23 is rotated, the nut lever 231 is moved counterclockwise, whereby the roller 233 lifts the lower retraction slide 251 in order to retract the lower espagnolette rod 25.

[0054] Furthermore, the lock housing 21 comprises a control device 7 according to the Figures 3 and 4 The embodiment shown. The control device 7 is connected to the motor 3 in order to control it. The control device 7 and thus the motor 3 are electrically connected via the multi-core connecting cable 18 and are supplied with electrical energy and control signals via this cable 18.

[0055] The control device 7 is connected to several sensors that are arranged in the lock housing 21 and interact with various components of the lock mechanism, for example, to detect their position. Thus, several sensors 71, 72, 73, 74 are provided in the area of ​​the slide plate 27 to detect the positions of the slide plate 27. A first sensor 71 is designed as a locking sensor to detect the locking position. A second sensor 72 is designed as a center position sensor to detect the center position. A third sensor 73 is designed as an unlocking sensor to detect the unlocking position. A fourth sensor is designed as a bolt retraction sensor 74. The sensors 71, 72, 73, 74 are each designed as a light barrier and are passed through by a flag on the motor nut. Alternatively, the sensors 71, 72, 73, 74 can also be designed as buttons or as Hall sensors.

[0056] For example, a control signal can be received via control device 7 to unlock the espagnolette lock. Control device 7 then controls motor 3, starting from the locked position. Motor 3 moves slide plate 27 parallel to faceplate 22 until it reaches the unlocked position. This is detected by the unlocking sensor 73 and reported to control device 7. Control device 7 then switches off motor 3. Similarly, using control device 7 and center position sensor 72, espagnolette lock 2 can be motor-driven to the center position.

[0057] The espagnolette lock further includes a further sensor, designed as a latch contact 42, for detecting the position of a latch of an active leaf lock. When the active leaf is closed and the espagnolette lock 2 is locked, the latch of the active leaf lock engages in the latch receiving space of the lock housing 21, thereby actuating the latch contact 42. The control device 7 is connected to the latch contact 74 and evaluates its signal to detect the latch of the active leaf lock.

[0058] Furthermore, the espagnolette lock 2 includes a further sensor, designed as a bolt contact 51, for detecting the position of a bolt of an active leaf lock. When the active leaf is closed and the espagnolette lock 2 and the active leaf lock are locked, the bolt of the active leaf lock engages in the bolt receiving space of the lock housing 21, thereby actuating the bolt contact 75. The control device 7 is connected to the bolt contact 75 and evaluates its signal to detect the bolt of the active leaf lock.

[0059] The lock further comprises several sensors 75, 76, 77, 78, 79 for detecting the positions of lock components. Sensors 75, 76, 77, 78, 79 are connected to control device 7 and are evaluated by it or linked to a higher-level control center via cable 18. Sensor 75 is designed as a latch ejector sensor to detect the position of latch ejector 4. Sensor 76 is designed as a follower sensor to detect actuation of follower 23. Sensor 77 is designed as a top / bottom locking sensor to detect the position of the retracting slides 241, 251 or the deflection lever 26. Sensor 78 is designed as a bolt ejector sensor to detect the position of bolt ejector 5. The sensor 79 is designed as a manipulation sensor to detect manipulation of the drive bolt rods 25, 24.Sensors 75, 76, 77, 78, and 79 are each designed as light barriers and are passed through by a switching flag. Alternatively, sensors 75, 76, 77, 78, and 79 can also be designed as pushbuttons or Hall sensors.

[0060] In total, the espagnolette lock 2 has the following sensors: Bolt contact 51, latch contact 42, locking sensor 71, center position sensor 72, unlocking sensor 73, bolt retraction sensor 74, latch ejector sensor 75, follower sensor 76, top / bottom locking sensor 77, bolt ejector sensor 78, manipulation sensor 79. There are 11 sensors in total, so the quantity S = 11. According to the example of the Figures 3 and 4 The number of connecting poles is A = 7, or A = 5, since two poles are required for the power supply. Of course, the specialist can vary the number of connecting poles according to requirements, i.e., reduce or increase them.

[0061] The operating mode of the interface 82 can be set via the control device 7 using the selector switch 82. This allows you to specify whether the espagnolette lock is connected to a digital bus (bus mode) or wired directly or discretely (direct mode). In direct mode, the selector switch 84 can be used to specify which of the sensors sends its signal via cable 18 to a higher-level control center, for example, an access control device or an alarm system.

[0062] The direct mode is described below: If the switch 83 is switched to D, i.e. direct mode, the interface 82 is switched to direct mode, i.e., discretely wired. In the example shown, the Figures 3 and 5The connecting cable 18 is designed as a seven-core cable. Therefore, not all of the 11 sensors can be queried in Direct Mode. In addition, Motor 3 must be controlled and the control device must be supplied with power. Therefore, in Direct Mode, fewer than the seven cores of the cable are available for the 11 sensors, i.e. only five cores (minus 2 power supply), or only four cores (another cable less due to Motor 3). The selector switch 84 can be used to set which of the 11 sensors is connected to the connection poles or core connections of the interface 82. This significantly reduces the wiring and installation effort, as fewer connections need to be provided and fewer connections need to be occupied. Thinner multi-core cables can also be used, which likewise reduces the installation effort. Of course, more or fewer cores in the connecting cable are also conceivable to cover additional applications.

[0063] If multiple sensors are to be queried by a higher-level control center, the number of wires and connection pins can be increased accordingly. For example, an 8-wire or 9-wire cable with a corresponding number of connection pins of the control unit 7 can be used.

[0064] If fewer sensors are to be queried by a higher-level control center, the number of wires and connection pins can be reduced accordingly. For example, a 6-wire or 5-wire cable with a corresponding number of connection pins of the control device 7 can be used.

[0065] The bus mode is described below: If the switch 83 is switched to B, i.e. bus mode, the interface 82 is switched to bus mode or bus mode ( Figure 4In bus mode, a serial data bus, such as a CAN bus or a Hi-O bus, or an ASi bus, can be connected to interface 82. The type of data bus to be connected can be set using selector switch 84. The control device 7 can communicate with a higher-level control center via the data bus. All sensors 71, 72, 73, 74, 75, 76, 77, 78, 79, 51, 42 can be queried via a data bus, and the motor 3 can be controlled without restrictions.

[0066] In the Fig. 6 the deadbolt lock 2 is in accordance with Fig. 5 shown in a motor-driven unlocked position. To motor-driven unlock the espagnolette lock 2, the motor 3 is actuated so that the spindle nut 33, as shown in Fig. 6shown, is moved upwards along the spindle 32 and thereby takes the slide plate 27 along with it. The driving takes place via the first stop surface 331 and second stop surface 332, which are each connected to the two stop pins 271, 272, which, for example, in Fig. 5 are shown, are in contact and thus take the slide plate 27 with them as they move upwards along the spindle. The slide plate leaves the switching range of the locking sensor 71, moves into the unlocked position, and there actuates the unlocking sensor 73.

[0067] The locking slide lever 28 is guided with its first locking slide arm 281 or the upper locking slide arm 281 in the guide rail 273 of the slide plate 27. As a result of the movement of the slide plate 27 parallel to the face plate 22 upwards according to Fig. 3, the bolt slide lever 28 is pivoted counterclockwise by the guide rail 273. Consequently, the lower or second bolt slide arm 282 pushes the bolt ejector 5 into the Fig. 6 The unlocking position shown in FIG. 1 is shown in FIG. 2, in which the end of the bolt slide 5 projects beyond the face plate 22. The latch ejector 4 is also moved out of the lock housing 21 into the position shown in FIG. 1 via the reversing lever 41, which is connected to the first bolt slide arm 281. Fig. 6 Move to the unlocking position shown.

[0068] In Fig. 7The slide plate 27 is cut away and the principle of unlocking the espagnolette bars when the slide plate 27 is motor-operated is shown. The slide plate 27 has a slide roller 274 which interacts with a control cam 263 of the reversing lever 26. The reversing lever 26 is mounted so as to be rotatable about the pivot point 264. The control cam 263 is arranged on the first arm 261 of the reversing lever 26. As a result of the movement of the slide plate 27 upwards along the arrow shown, the slide roller 274 pushes the first arm of the reversing lever 26 upwards, whereupon the lower retraction slide 251, which is connected to the first arm 261 via the point of action 254, also moves upwards, so that the lower espagnolette bar 25 is pushed into the lock housing 21 of the espagnolette lock 2.At the same time, the second arm 262 of the reversing lever 26 moves downward, taking with it the upper feed slide 241, which is connected to the reversing lever 26 or its second arm 262 via the guide pin 265. The connection of the lower feed slide 251 to the reversing lever 26 is shown in detail in . Fig. 8 The connection of the upper feed slide 241 to the reversing lever 26 is shown in detail in the Fig. 9 shown. During unlocking, the bell crank 26 is pivoted along the arrow shown around the pivot point 264.

[0069] The upper section of the slide plate 27 shows the guide rail 273, in which the guide pin 283 of the locking slide lever 28 is guided. The guide rail 283 has two differently oriented guide rails 275, 276. The first guide rail 275 runs obliquely to the unlocking direction to pivot the locking slide lever 28 between its locked position and the unlocked position. When the slide plate 27 moves, the guide pin 283 runs along the guide rail 273. The first link section 275 runs obliquely to the direction of movement of the slide plate 27. The second link section 276 runs parallel to the direction of movement of the slide plate 27. The link pin 283 is displaced laterally within the first link section 275 when the slide plate 27 moves, thereby pivoting the locking slide lever 28.If the guide pin 283 is located in the second guide area 276, it is not displaced laterally. It remains stationary when the slide plate 27 continues to move in the unlocking direction (parallel to the face plate 22 upwards), thus holding the bolt slide lever 28 in its unlocked position, in which the bolt ejector 5 and the latch ejector 4 have each reached their unlocked positions.

[0070] When moving the deadbolt lock 2 from the locked position according to Fig. 5 The spring drive 6 of the drive bolt lock 2 is loaded into an unlocked position. The spring drive 6 of the drive bolt lock 2 comprises two compression springs 61 and 62. The compression spring 61 acts on the slide plate 27. The compression spring 62 acts on the lower retraction slide 251. As can be seen by comparing the Figures 5 and 6As can be seen, when the espagnolette lock is unlocked, the two springs 61 and 62 are compressed. In order to move the espagnolette lock 2 from the unlocked position according to Fig. 6 back to the locked position according to Fig. 5 to guide, the spring drive 6 is released so that the espagnolette lock 2 is returned to its locked position while discharging the energy stored in the springs 61 and 62.

[0071] In addition to the Fig. 6 The motorized unlocking position of the deadbolt lock 2 shown in Fig. 10 the unlocking of the espagnolette lock 2 is shown in a manual manner by turning the lock nut 23. By turning the lock nut 23 counterclockwise, the nut lever 231 is also turned counterclockwise, whereby, as in Fig. 11Shown enlarged, the roller 233 of the nut lever 231 carries the lower retraction slide 251 upwards. This occurs when the roller 233 is in contact with the slide stop surface 252 and, when the nut lever 231 is rotated, this is actuated upwards together with the retraction slide 251. In this case, the reversing lever 26 is pivoted, as previously with the motorized unlocking, and carries the upper retraction slide 241 downwards, which leads to the immediate retraction of the driving bolt rods 24 and 25.

[0072] When manually unlocking using the nut lever 231, it should be noted that the rotational speed of the reversing lever 26 is, at least initially, higher than with the motorized unlocking. Fig. 7As can be seen from the dashed lines, the effective lever 91 between the point of application 254 and the pivot point 264 of the bell crank is greater than the effective lever 92 between the pin of the slide plate 274 and the pivot point 264 of the bell crank 26. This has the effect that when the lock nut rotates, i.e. during manual unlocking, the bell crank 26 disengages from the slide roller 274, in particular lifts off from it. This separates the unlocking of the espagnolette bars from the motor influence. This means that the manual unlocking cannot be influenced by the motor 3, so that it is guaranteed at all times that the espagnolette lock 2 can be unlocked manually via the lock nut 23.

[0073] Furthermore, the nut lever 231 has a driver 232 to drive the locking slide lever 28. As in Fig. 10As shown, due to the stop between the driver 232 and the bolt slide lever 28, the latter is also rotated counterclockwise when the lock nut 23 is actuated in order to move the latch ejector 4 and the bolt ejector 5 into the unlocked position. As a result of the rotation of the bolt slide lever 28, the slide plate 27 is also actuated upwards parallel to the face plate. This is shown in Fig. 10 This is illustrated by the fact that the stop pins 271 and 272 are lifted from the stop surfaces 331 and 332 of the spindle drive 31, i.e., they are not operatively engaged. However, since the slide roller 274 follows the reversing lever, i.e., the reversing lever is not engaged with the slide plate, this displacement of the slide plate 27 has no disruptive influence on the mechanical or manual unlocking of the deadbolt lock.

[0074] In Fig. 11It is shown that the roller 233 of the nut lever 231 runs on a slide stop surface 252 of the lower feed slide 251.

[0075] When motor-driven unlocking of the deadbolt lock 2 as in Fig. 6 As shown, the nut lever 231 remains stationary. The lower feed slide 251, however, is moved upward by a motor. This causes the slide stop surface 252 to lift off the roller 233 of the nut lever.

[0076] Based on the Fig. 10 The locking of the drive bolt lock 2 is again made possible in the same way by the support of the spring drive 6. In Fig. 8 It can be seen that both springs 61 and 62 of the spring drive 6 are charged. With the support of these two springs 61, 62, the deadbolt lock 2 can be opened from the position shown in Fig. 10shown unlocking position back to the locked position according to Fig. 5 be spent.

[0077] In the Fig. 12 For a better overview, the interaction between the bolt slide lever 28 and the latch ejector 4 is shown. According to the illustration in Fig. 12 The trap ejector 4 is connected to the trap deflection lever 41 by means of a pin guided in a guide. Fig. 13 shows the connection of the latch ejector 4 to the latch deflection lever 41. The latch deflection lever 41 is designed as a two-armed pivot lever, the other arm of which is also guided via a pin in a link of the first bolt slide arm 281. If for unlocking as in Fig. 12 indicated by an arrow, the bolt slide lever 28 is turned counterclockwise, the latch deflection lever 41 reverses the movement, which leads to the latch ejector 4 being in the Fig. 13shown arrow direction out of the lock housing 21 of the espagnolette lock 2 in order to unlock a locking element, in particular a latch of an active wing lock.
