Description

The invention relates to a closure for a window, a door or the like, the window, the door or the like having a frame and a sash movable with respect to the frame and the closure in the assembled state is designed to releasably fix the sash to the frame, the Closure comprises a base body designed for attachment to the frame or on the wing and several components that are movable relative to the base body, and wherein several functional states of the closure are defined by different positions of the movable components.

Such locks are generally used to lock or unlock windows, doors, gates or the like. The base body can be designed for receiving and fastening in a fitting groove of the frame or of the sash. The moving components can be locking, control, power transmission and deflection elements. A generic closure is for example in the WO 2017/016809 A1 disclosed.

There is an effort to improve the security of closures of the type mentioned and in particular to avoid incorrect operation and manipulation.

A closure according to the invention comprises a sensor arrangement which is designed to monitor the different positions of the movable components and to output the respective position signals, as well as an electronic evaluation device which is designed to receive the position signals and, based on a comparison of the position signals with the respective default values, a status signal to generate, which indicates the current functional state of the closure.

The status signal can be used to identify malfunctions of the lock, mechanical defects, attempts at manipulation, attempted break-ins and the like, so that suitable countermeasures can be taken. Knowledge of the current functional state is also of advantage in the context of the intended locking operation, for example in order to control the lock depending on the state. The invention is based in particular on the knowledge that by monitoring the positions of the movable components, it is possible in a relatively simple manner to distinguish between different functional states of the lock. The default values can be taken from a memory device assigned to the evaluation device.

The electronic evaluation device can be designed to output an error signal as a status signal if the position signals indicate an impermissible combination of positions of the movable components. In general, only certain combinations of positions of the movable components are possible when the lock is used as intended, while other combinations do not correspond to any intended functional state and are therefore to be regarded as inadmissible. Such impermissible combinations can be recognized on the basis of the error signal. Since impermissible combinations are generally the result of incorrect operation, manipulation or defects, an error is detected by the electronic evaluation device if such a combination occurs. The error signal can be output to a, for example optical or acoustic, warning device and / or to a higher-level control device. The warning device can be integrated into the electronic evaluation device.

According to one embodiment of the invention, the sensor arrangement comprises a plurality of sensors, in particular proximity sensors, which are fixedly arranged on the base body and are each designed to detect a component of the movable components that is located at a predetermined position. This enables particularly simple position monitoring. Proximity sensors which respond in a contact-free manner are preferably provided, which are distinguished by freedom from wear and insensitivity to contamination and vibrations.

To monitor the positions it is not absolutely necessary to record them as values. Rather, in certain applications it may be sufficient to merely differentiate between the position information “component in the relevant position” and “component not available in the relevant position”. However, continuous measurement for position monitoring can be beneficial in certain situations.

The sensors can be designed as Hall sensors which are designed to detect the respective magnetic areas of the moving components. Hall sensors work over a relatively wide temperature range and have a long service life. They are therefore particularly suitable for use in window and door closures. The Hall sensors can be applied to a common printed circuit board that is attached to the base body. This enables a particularly compact design. The magnetic areas can be formed, for example, by permanent magnets that are glued onto the movable components. To have to then do not lead any electrical lines to the moving components.

Alternatively, the sensors can also be designed as reed contacts, light sensors, ultrasonic sensors or the like.

The movable components can comprise a locking element rotatably mounted on the base body, which defines a holding receptacle for a locking element attached to the sash or the frame and which can be moved between a release position that releases the locking element in an opening direction of the sash and a blocking position that blocks the locking element in the opening direction, wherein the sensor arrangement is designed to monitor the rotational position of the closure element. The electronic evaluation device can thus recognize whether the lock is open or closed.

Depending on the application, the base body can be provided for attachment to the frame and the locking element for attachment to the sash, or vice versa. According to one embodiment of the invention, the locking element can be a simple pin, in particular a roller pin. In particular, the pin can have a cylindrical cross-section in order to enable particularly easy sliding into the holding receptacle of the closure element. In order to increase the protection against unauthorized opening of the lock, the pin can be designed as a mushroom pin. The closure element can be pivotable between its release position and its blocking position, for example about a pivot axis running transversely to the opening direction. This enables a particularly simple construction.

A further embodiment of the invention provides that the lock includes the locking element and the sensor arrangement includes a proximity sensor which is arranged in the area of the holding receptacle of the locking element in the blocking position and is designed to detect the locking element in the holding receptacle. The electronic evaluation device can thereby recognize whether the locking element is in the holding receptacle, that is to say whether the wing is closed, or not. If the lock is locked and the locking element is accordingly in the blocking position, although there is no locking element in the holding receptacle, an undesirable functional state is present. Such a situation can occur, for example, when the closure element is moved manually in the direction of the blocking position when the sash is open. The detection of such a state is important because, when the sash is subsequently closed, the locking element can hit the closed closure element hard. This can be prevented by placing the closure element in the release position in good time.

The electronic evaluation device can therefore be designed to output an error signal as a status signal when the locking element is in the blocking position and the locking element is not in the holding receptacle. The electronic evaluation device or a control device connected to it can be designed to return the locking element to the release position in this case in order to prevent the locking element from hitting the locking element when the sash is subsequently closed.

The movable components can comprise a locking slide, which is slidably guided between a locking position and an unlocking position in the base body and is pretensioned by at least one spring in the direction of its locking position, the locking slide in the locking position preventing a movement of the locking element from the blocking position into the release position and in the unlocked position allows a movement of the locking element between the blocking position and the release position, and wherein the sensor arrangement is designed to detect the locking slide located in the locking position and in the unlocking position. The locking element is automatically moved into its blocking position by closing the sash, the reopening of the sash being prevented by the locking slide. The sash is thus secured against unwanted opening immediately after the closing process, even if the user only gave it a slight “push”. In order to be able to open the sash again, the bolt slide must be returned to its unlocked position, which can be done for example by operating a handle such as a door handle or an actuator such as an electric motor. The position of the bolt slide provides information about whether or not a sash opening is possible.

A lock according to the invention can comprise a motor which is arranged on the base body and which is coupled with the locking slide in such a way that it is effective for driving purposes and that it approaches or moves away from the unlocking position depending on the direction of rotation of the motor. An electronic control device can be provided which is connected to the motor and to the evaluation device and is designed to output a control instruction to the motor as a function of the status signal. This enables a state-dependent Lock control, which facilitates the provision of an at least largely automatic lock.

According to a special embodiment, the motor comprises an output shaft which is drivingly coupled to a spindle drive which converts the rotational movement of the output shaft of the motor into a displacement movement of the locking slide, the spindle drive comprising a drive spindle driven by the motor and a spindle nut which is drivingly connected to the Latch slide is coupled, wherein the sensor arrangement is designed to monitor the position of the spindle nut. Since the locking slide and the spindle nut can be moved independently of one another within the framework of the stroke of the spring, knowledge of both positions is beneficial for characterizing the functional state of the lock.

The locking slide can have a day position between the locking position and the unlocking position, in which it can be deflected in the direction of the unlocking position as a result of a movement of the locking element between the blocking position and the release position while overcoming the spring force of the spring, the sensor arrangement being designed to respond to the in Detecting the dead bolt carriage.

If only relatively small forces act on the sash in the daytime position of the bolt slide, a movement of the locking element from the blocking position into the release position is prevented and the sash is thus held conditionally in its closed position. If, on the other hand, relatively large forces act on the sash in the daytime position of the locking slide, this means that the locking element can move from a blocking position into its release position, whereby the locking slide can be deflected in the direction of its unlocking position while overcoming the spring force of the spring. In the daytime position of the bolt slide, the locking element is held in its blocking position to prevent unintentional opening of the sash, whereas the locking element can be transferred to its release position with correspondingly large opening forces acting on the sash without having to unlock the bolt slide beforehand.

A further embodiment of the invention provides that the control device is designed to move the locking slide into the locked position or a holding position between the daytime position and the locked position and only after a predetermined one has expired when the locking slide is in the daytime position and the locking element is moved into the blocking position To set the duration back to the day position. In this way, an undesired opening of a thrown wing can be prevented.

The predefined time period is preferably at least 10 ms and at most 2 s. That is to say, it is preferred to only move to the locked position or holding position for a short time so that there is no significant interruption of the daytime position function.

A control device of the lock can be designed to move the bolt slide into the locking position only when the locking element is in the blocking position. This can prevent undesired wedging of the components.

The closure element can have a closed position, the blocking position being between the closed position and the release position, and the locking slide in its blocking position allowing the closure element to move between its blocking position and its closed position. The sensor arrangement can be designed to distinguish between the blocking position, the release position and the closed position.

The locking slide can have a locking position, the locking position being between the locking position and the unlocking position, the locking slide and the locking element cooperating in a drivingly effective manner in such a way that the locking element assumes the locking position when the locking slide moves out of its locking position into its locking position, and the The sensor arrangement is designed to detect the bolt slide located in the locking position.

According to a special embodiment, a rotatably mounted gear element, in particular an at least partially toothed gear or a lever, is provided on the base body, via which the locking slide and the locking element interact in a driving manner, the sensor arrangement being designed to be based on the rotational position of the gear element monitor the rotational position of the closure element.

A return spring can be provided, by means of which the closure element is pretensioned directly or indirectly in the direction of the release position.

According to a further embodiment of the invention, the movable components comprise a closure element which has a holding receptacle for a one attached to the sash or the frame Defined locking element and is movable between a release position releasing the locking element in an opening direction of the sash and a blocking position blocking the locking element in the opening direction, the closure element being automatically movable from the release position in the direction of the blocking position when the closure is installed by a closing movement of the sash, and a Locking element that can be moved between a locked position and an unlocked position, the locking element preventing movement of the locking element from the locking position into the unlocking position in the locking position and allowing the locking element to move between the locking position and the unlocking position in the unlocking position, the locking device having a motor for driving the locking element and a control device for controlling the motor, and wherein the control device is designed to, when the locking element moves into the B locking position to put the locking element in the locked position and after a predetermined period of time again in the direction of the unlocked position. This can prevent an undesired opening of a thrown wing.

The invention also relates to a window, a door or the like with a frame, a sash movable relative to the frame and at least one lock for releasably fixing the sash on the frame.

According to the invention it is provided that the closure is designed as described above and the base body is attached to the frame or to the sash.

The 1 shows a plan view of a closure according to the invention 10 , which has an elongated body 12 having the individual components of the closure 10 takes up and thus serves as a kind of housing. In particular, the base body 12 two opposite and in the longitudinal direction of the base body 12 running side walls 13 on, between which the individual components of the closure described in more detail below 10 are arranged. Like the one in particular 6th can be removed, the main body 12 has a relatively small width and depth and can thus be in a fitting groove by means of the lock 10 to be secured wing.

As in turn the representation of the 1 can be removed is on the base body 12 a claw-shaped locking element 14th around a pivot axis 15th pivoted. The closure element 15th assigns a recording 16 in the form of a groove open on one side, the width of which is such that a cylindrical locking element 60 fits in, which is intended for attachment to the sash of the window or door and in 1 from the shutter 10 is shown spaced. In principle, however, it could also be provided that the base body 12 for attachment to the sash and the locking element 60 is designed for attachment to the frame.

At the holding fixture 16 opposite side has the closure element 14th a toothing 17th on which with a toothing 18th that combs on a gear element 19th is formed on the base body 12 around a pivot axis 11 is pivotably mounted. On the the Interlocking 18th opposite side forms the gear element 19th a projection, also referred to here as a slide cam 20th whose function will be discussed in more detail below.

Furthermore, the closure 10 one in the longitudinal direction of the same movable locking slide 21st on, the one on the gear element 19th facing side a locking cam 22nd forms, which with the slide cam 20th interacts, as will also be explained in more detail below.

Furthermore, the closure 10 one on the main body 12 arranged electric motor 23 on, which is so effective as a drive with the bolt slide 21st is coupled that this depends on the direction of rotation of the motor 23 can move in different directions. The engine drives more precisely 23 a drive spindle 24 a spindle drive 25th ( 2 ) by turning the drive spindle 24 a spindle nut arranged on it 26th in a manner known per se in the longitudinal direction of the drive spindle 24 is proceeded. On the spindle nut 26th is the bolt slide 21st supported so that this together with the spindle nut 26th depending on the direction of rotation of the drive spindle 24 can be moved in different directions.

For the energy supply of the electric motor 23 has the closure 10 Via an energy store such as a battery and / or an induction coil, which is not shown in the figures. The power supply of the electric motor 23 could also be wired.

Again 1 in turn can be removed is the bolt slide 21st about two springs 28 on the spindle nut 26th supported so that the bolt slide 21st with fixed spindle nut 26th opposite the same against the spring force of the springs 28 can be deflected. On the other hand, the spindle nut 26th with fixed bolt slide 21st be moved relative to the same. However, there is relative mobility between the spindle nut 26th and bolt slide 21st limited by two stops (not visible) spaced from one another in the axial direction of the drive spindle, so that the bolt slide 21st after reaching the respective stop by the spindle nut 26th can be taken from the same.

1 shows a position of the shutter 10 , in which the closure element 14th in its release position F. is located in which the claw-shaped portion thereof is through an opening 29 in the housing wall 13 extends. In this position, the locking element 60 into the holding fixture 16 slide in, whereupon the closure element 14th with continued closing movement of the sash clockwise in the direction of the 3 and 4th shown blocking position B. of the closure element 14th is pivoted.

As the closure element 14th and the gear element 19th over the two gears 17th , 18th mesh with each other, is the gear element 19th pivoted counterclockwise. This pivoting movement of the closure element 14th and the gear element 19th is in the 1 The position shown is therefore possible because the bolt slide 21st in its unlocked position E. which he occupies when he is using the spindle drive 25th in the direction of the electric motor 23 was pulled. In this unlocked position E. can the slide cam 20th of the gear element 19th not with the locking cam 22nd of the bolt slide 21st collide, which is why the closure element 14th can be pivoted freely in the manner described above.

The closure element 14th is by means of a return spring, not shown here, in the direction of its release position F. preloaded, this spring either directly on the closure element 14th or on the gear element 19th and thus indirectly on the closure element 14th can act.

Is the locking element 14th according to the preceding explanations for 1 based on the release position shown F. in the in the 4th Blocked position shown B. has been pivoted, so can by the bolt slide 21st a movement of the closure element 14th back to its release position F. be prevented, as in the 4th is shown. In the 4th the bolt slide is located 21st in its locked position S. in which he is elastic by means of the springs 28 being pushed. In this locked position S. the locking cam engages behind 22nd of the bolt slide 21st the slide cam 20th of the gear element 19th such that a movement of the closure element 14th from his in the 4th shown blocking position B. back to its release position F. is prevented.

Alternatively, however, it is also possible to use the bolt slide 21st in advance by energizing the motor 23 by means of the spindle drive 25th in the in the 2 shown waiting position W. to transfer, in which the locking cam 22nd at the end with a convex curved sliding surface section of the sliding cam 20th is in contact with or is in contact with it, with the bolt slide 21st in this waiting position W. by means of the springs 28 against the slide cam 20th is elastically biased.

Will be in this waiting position W. of the bolt slide 21st the closure element 14th from the release position shown F. in its blocking position B. according to 4th pivoted so slides here the slide cam 20th with its convexly curved counter-sliding surface 30th on the face of the locking cam 22nd along, making the bolt slide 21st towards its unlocked position E. against the preload force of the springs 28 is elastically deflected. Once then the closure element 14th its blocking position B. has reached and thereby the slide cam 20th counterclockwise on the locking cam 22nd has moved past the bolt slide 21st by the preload of the springs 28 about his waiting position W. out to its locked position S. pushed into which the locking cam 22nd the slide cam 20th according to 4th engages behind, whereby the closure element 14th in the blocking position shown B. is secured.

To the closure element 14th in its blocking position B. to be able to secure against low opening forces as part of the day function, whereas the closure element 14th with greater opening forces starting from the blocked position B. back to its release position F. should be able to be swiveled, has the bolt slide 21st between the in the 4th shown locking position S. and the one in the 1 unlocked position shown E. one here as a day position T designated intermediate position, as shown in the 3 is shown. In this day position T shows the bolt slide 21st opposite the spindle nut 26th the same relative position as in the locked position ( 4th ) on; however, the bolt slide was 21st by means of the spindle drive 25th or the spindle nut 26th a little way back towards its unlocked position E. drawn, as shown by a comparison of the respective positions of the bolt slide 21st according to 3 and 4th emerges.

In the day position according to 3 the sliding cam lies 20th on a sliding surface 31 of the locking cam 22nd on, this sliding surface 31 forms a ramp or is inclined like a ramp in such a way that the bolt slide 21st against the spring force of the springs 28 towards its unlocked position E. is deflected when the slide cam 20th due to a pivoting movement of the closure element 14th counterclockwise towards its release position F. is pivoted in the clockwise direction. So is the opening force on the closure element 14th sufficiently large, this means that the bolt slide 21st contrary to the holding resistance of the springs 28 towards its unlocked position E. is deflected and thus the movement of the closure element 14th as well as the closure element 19th releases. The sliding cam 20th partially moves on the locking cam 22nd clockwise and slides along the face of the same.

During this movement sequence, the gear element experiences 19th through the bolt slide 21st initially a counterclockwise torque; due to the convex shape of the counter sliding surface 30th of the sliding cam 20th takes this counterclockwise torque with increasing rotation of the gear element 19th clockwise until it increases again, but then clockwise. This variation in the torque that the transmission element 19th through the bolt slide 21st due to the spring preload by the springs 28 experiences, leads to a snapping of the closure element 14th so that the closure element 14th in the day position T of the bolt slide 21st has two defined end positions, namely the release position F. on the one hand and the blocking position B. on the other hand.

Because the slide cam 20th in the release position F. of the closure element 14th with its counter sliding surface 30th on the face of the locking cam 22nd is applied, the closure element 14th then again against that of the springs 28 applied resistance back into its blocking position B. be swiveled in the daytime position T of the bolt slide 21st is conditionally secured. In the day position T of the bolt slide 21st this can thus as a result of a movement of the closure element 14th against the spring force of the springs 28 towards its unlocked position E. be deflected.

The blocking position B. of the closure element 14th is angularly oriented in such a way that the sash does not lie close to the frame, so that a certain gap ventilation is still possible. The closure element 14th can, however, based on the release position F. about the blocking position B. out into an in 5 shown closed position SS be pivoted so as to clamp the sash tightly to the frame.

The bolt slide is used for this 21st starting from the in the 4th shown locking position S. by means of the spindle drive 25th further in the direction of the gear element 19th or the closure element 14th proceed. First the spindle nut 26th in the direction of the bolt slide 21st move until the spindle nut 26th on the bolt slide 21st abuts, so that this with continued movement of the spindle nut 26th from its locked position S. in the direction of its locking position V is moved. The sliding cam rides during this movement sequence 20th continue on the sliding surface 31 of the locking cam 22nd on what has the consequence that the gear element 19th is pivoted further counterclockwise. The closure element 14th is thus clockwise in its closed position SS pivoted, whereby the sash is pulled firmly against the frame. Because the distance between the point where the sliding surface 31 of the locking cam 22nd with the slide cam 20th is in contact, and the pivot axis 11 of the gear element 19th is greater than the distance between the pivot axis 11 of the gear element 19th and the power transmission point between the teeth 17th , 18th , the gear element acts 19th as a reduction gear. The gear element 19th however, it can equally be replaced by a two-armed lever with lever arms of different lengths.

If the sash is to be opened again, the bolt slide is 21st at least temporarily back in his in the 1 unlocked position shown E. moves in which the bolt slide 21st allows the closure element 14th by either on the closure element 14th or on the gear element 19th acting return spring back into its release position F. can swing.

In the embodiment described above, the closure element 14th thereby in the direction of its closed position SS pulled that the slide cam 20th through the ramp-shaped sliding surface 31 of the locking cam 22nd is deflected when the bolt slide 21st in the direction of its locking position V is proceeded.

Alternatively, the transmission element 19th using a toggle mechanism with the bolt slide 21st be coupled, which its effect to deflect the closure element 14th towards its closed position SS unfolded when the bolt slide 21st in its locked position V is proceeded. This toggle mechanism comprises according to the 7th and 8th a coupling lever 32 on the one hand on the bolt slide 21st , especially on its locking cam 22nd , and on the other hand on the gear element 19th , especially on its slide cam 20th is hinged. The articulation point at which the coupling lever 32 while doing this on the bolt slide 21st is articulated, is thereby by a pivot pin 33 formed in one in the bolt slide 21st trained elongated hole 34 is displaceably mounted. This slot guide 33 , 34 allowed in the day position T of the bolt slide 21st a deflection of the same in the direction of its unlocked position E. as is required, among other things, to implement the day function.

Will the spindle nut 26th starting from the in the 7th position shown in the direction of the bolt slide 21st move, this arrives with the bolt slide 21st in attachment, whereupon this from the spindle nut 26th is taken. With continued movement of the spindle nut 26th then the pivot pin arrives 33 in contact with the end of the elongated hole 34 which of the spindle nut 26th is facing, whereupon with continued movement of the spindle nut 26th the coupling lever 32 around its articulation point on the gear element 19th is pivoted clockwise with the result that the transverse to the direction of movement of the bolt slide 21st measured dimension between the two articulation points of the coupling lever 32 increases. This in turn has the consequence that the transmission element 19th Swiveled counterclockwise and thus the closure element 14th clockwise towards its closed position SS is pivoted, see also the 8th .

As can be seen from the above, are through different positions of the closure element 14th , the gear element 19th , the bolt slide 21st and the spindle nut 26th a number of different functional states of the closure 10 Are defined. A sensor arrangement 50 serves to set the different positions of the closure element 14th , the gear element 19th , the bolt slide 21st and the spindle nut 26th to monitor and output the respective position signals. In the 1-5 , 7th and 8th is the sensor arrangement 50 each shown in the lower part of the picture in a schematic individual view.

In detail, the sensor arrangement comprises 50 eight Hall sensors 55A-H , which are at predetermined positions on a common, in the base body 12 housed board are arranged. The Hall sensors 55A-H act with a total of four permanent magnets 57A-D together, one of which on the locking element 60 , on the gear element 19th , on the bolt slide 21st and on the spindle nut 26th is upset.

In the individual illustration in the lower part of the picture, the positions shown correspond to the permanent magnets 57B , 57C , 57D each of the positions of the transmission element shown in the upper part of the picture 19th , the bolt slide 21st and the spindle nut 26th . It should be noted that the scale of the representation of the sensor arrangement 50 in the lower part of the picture opposite the representation of the lock 10 is stretched in the upper part of the picture, so the positions of the Hall sensors 55B-H and the permanent magnets 57B-D in the individual parts of the picture do not exactly correspond. The one on the locking element 60 applied permanent magnet 57A and the associated, in 1 Hall sensors 55A located furthest to the left are omitted in the individual illustrations and, for the sake of simplicity, only in the upper part of FIG 1 shown.

This Hall sensor 55A is at one point on the base body 12 arranged on which the locking element 60 with the permanent magnet 57A when the wing is fully closed. The Hall sensor 55A can therefore be used to detect whether the wing is closed or not.

The second hall sensor 55B seen from the left works with a permanent magnet 57B together that is on the gear element 19th is upset. When the gear element 19th as in 1 shown in the release position F. the permanent magnet is located 57B outside the detection range of the Hall sensor 55B so that it outputs a negative detection signal. When the gear element 19th however as in 3 and 4th shown in the blocked position B. the permanent magnet is located 57B in the detection range of the Hall sensor 55B so that it outputs a positive detection signal. Using the Hall sensor 55B it can therefore be determined whether the closure element 14th in the blocked position B. or in the release position F. is located.

The third hall sensor 55C seen from the left works with a permanent magnet 57C together, the one on the bolt slide 21st is upset. When the bolt slide 21st as in 1 shown in the unlocked position E. or as in 2 shown on hold W. the permanent magnet is located 57C outside the detection range of the Hall sensor 55C so that it outputs a negative detection signal. When the bolt slide 21st however as in 4th shown in the locked position S. or as in 5 shown in the locked position V the permanent magnet is located 57C in the detection range of the Hall sensor 55C so that it outputs a positive detection signal. When the bolt slide 21st as in 3 shown in the day position T the permanent magnet overlaps 57C already with the detection range of the Hall sensor 55C so that it outputs a positive detection signal in this case too. Using the Hall sensor 55C can therefore be determined in particular whether the bolt slide 21st in the locked position S. or in the unlocked position E. is located. By providing a further Hall sensor or providing sufficient spatial resolution, it is also possible, if necessary, to switch between the unlocked position E. , the waiting position W. , the day position T , the locked position S. and the locking position V can be distinguished.

The other hall sensors 55D-H act with a permanent magnet 57D together that on the spindle nut 26th is upset. Using the Hall sensors 55D-H can switch between five different positions of the spindle nut 26th a distinction is made between those in 1-5 , 7th and 8th viewed from right to left as first open position 01, second open position O2 , Locking position A. , first closed position G1 and second closed position G2 are designated. 1 shows the spindle nut 26th in the first open position 01, 2 in the second open position O2 , 3 in the locked position A. , 4th in the first closed position G1 and 5 in the second closed position G2 .

One in the body 12 The electronic evaluation device housed, not recognizable in the figures, is connected to the Hall sensors 55A-H in connection and is designed to receive detection signals output by these and, based on a comparison of the detection signals with the respective default values, to generate a status signal which shows the current functional state of the lock 10 indicates. The status signal is output to an electronic control device (not shown) that works with the engine 23 and is connected to the evaluation device. The electronic control device is designed to control the engine 23 to be controlled depending on the status signal.

In particular, the electronic control device is designed to act as the closure element 14th in the release position F. to be set when an "open" command is received from a handle or a higher-level control or when the locking element 14th in the direction of the blocking position B. is moved and no locking element 60 on the main body 12 is detected. In the latter case, it can be assumed that there is an undesirable malfunction, which is caused by the opening of the closure 10 is to be fixed.

Furthermore, the electronic control device is designed to respond after the blocking position has been detected B. of the closure element 14th and the locking element 60 in the holding fixture 16 the bolt slide 21st by energizing the motor 23 automatically out of the unlocked position E. in the day position T or in the locked position S. to transfer to hold the sash on the frame.

To prevent the wing from being in the daytime position T of the bolt slide 21st pops up again after it has been thrown with momentum, it can further be provided that when it is determined that the closure element 14th based on its release position F. in its blocking position B. was pivoted, the bolt slide 21st temporarily in the direction of its locked position S. is transferred into a temporary holding position in which it is controlled by the slide cam 20th of the gear element 19th not back towards its unlocked position E. can be pushed. This temporary holding position is only approached briefly in order to prevent the sash from jumping open. Then the bolt slide can 21st back to its day position T be driven.

It goes without saying that the sensor arrangement 50 can also include sensors that output position value signals instead of detection signals. In addition, the sensor arrangement 50 include additional sensors to more advanced Distinctions between individual functional states of the lock 10 to enable.
