Description

The invention relates to a closure for a window, a door or the like, wherein the window, the door or the like has a frame and a sash that can be moved relative to the frame and the closure is designed in the assembled state for releasably fixing the sash to the frame, the Closure comprises a base body designed for attachment to the frame or the wing and a plurality of components that can move relative to the base body, and wherein a plurality of functional states of the closure are defined by different positions of the movable components.

Such closures 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 the sash. The moving parts can be closure, control, power transmission and deflection elements. A generic closure is for example in WO 2017/016809 A1 disclosed.

Efforts are being made 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 respective position signals, and an electronic evaluation device, which is designed to receive the position signals and based on a comparison of the position signals with respective ones Default values to generate a status signal which indicates the current functional status of the closure.

Malfunctions of the lock, mechanical defects, attempts at manipulation, attempted break-ins and the like can be detected on the basis of the status signal, so that suitable countermeasures can be taken. Knowledge of the current functional status is also advantageous within the context of the intended shutter operation, for example in order to control the shutter depending on the status. The invention is based in particular on the finding 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 closure. The default values can be taken from a storage 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, when the closure is used as intended, only certain combinations of positions of the moving components are possible, while other combinations do not correspond to any intended functional state and are therefore to be regarded as impermissible. Such impermissible combinations can be recognized on the basis of the error signal. Since impermissible combinations are generally the result of operating errors, manipulations or defects, the electronic evaluation device detects an error if such a combination occurs. The error signal can be output to a warning device, for example optical or acoustic, 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 in a predetermined position. This enables a particularly simple position monitoring. Preferably, proximity sensors that respond in a contact-free manner are provided, which are distinguished by their freedom from wear and their insensitivity to contamination and vibration.

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 present at the relevant position" and "component not present at the relevant position". However, a continuous measurement for position monitoring can be advantageous in certain situations.

The sensors can be in the form of 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 locks. 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 moving components. It must then lead no 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 closure element which is rotatably mounted on the base body and which defines a holding receptacle for a locking element which is fastened to the sash or to the frame and which can be moved between a release position which releases the locking element in an opening direction of the wing and a blocking position which 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 detect whether the closure 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 inadmissible levering open of the closure, the pin can be designed as a mushroom-head 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 closure comprises the locking element and the sensor arrangement comprises a proximity sensor which is arranged in the region of the holding receptacle of the locking element located in the blocking position and is designed to detect the locking element located in the holding receptacle. The electronic evaluation device can thus detect whether the locking element is in the holding receptacle, ie the leaf is closed, or not. If the closure is locked and the closure element is accordingly in the blocking position, although there is no locking element in the holding receptacle, a undesired functional state. This can occur, for example, if the closure element is moved manually in the direction of the blocking position when the leaf is open. The recognition of such a state is significant insofar as the locking element can hit hard against the closed closure element when the sash is subsequently closed. This can be prevented by setting 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 closure element is in the blocking position and the locking element is not in the retaining receptacle. The electronic evaluation device or a control device connected to it can be designed to reset the closure element back into the release position in this case in order to avoid the locking element hitting the closure element when the sash is subsequently closed.

The movable components can include a locking carriage, which is guided in the base body so that it can be displaced between a locked position and an unlocked position and is pretensioned by at least one spring in the direction of its locking position, with the locking carriage in the locking position preventing a movement of the closure element from the locking position into the unlocking position and in the unlocked position allows a movement of the closure element between the locked position and the unlocked position, and wherein the sensor arrangement is designed to detect the locking slide located in the locked position and in the unlocked position. Closing the wing automatically moves the closure element into its blocking position, with the bolt carriage preventing the wing from opening again. The sash is thus secured against unwanted opening immediately after the closing process, even if the user only gives it a slight "push". has given. In order to be able to open the wing again, the bolt carriage must be transferred back into its unlocked position, which can be done, for example, by actuating a handle such as a door handle or an actuator such as an electric motor. The position of the bolt carriage thus provides information as to whether a sash opening is possible or not.

A closure according to the invention can comprise a motor which is arranged on the base body and which is coupled to the bolt carriage in a drivingly effective manner in such a way that it approaches or moves away from the unlocked 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 state-dependent closure control, which facilitates the provision of an at least largely automatic closure.

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 motor's output shaft into a displacement movement of the bolt carriage, the spindle drive comprising a drive spindle driven by the motor and a spindle nut which is drivingly connected to the Bolt carriage is coupled, wherein the sensor arrangement is designed for monitoring the position of the spindle nut. Since the bolt carriage and the spindle nut can be moved independently of one another within the scope of the spring stroke, knowledge of both positions is beneficial for characterizing the functional state of the lock.

The locking carriage can have a day position between the locked position and the unlocked position, in which it is due to a movement of the closure element can be deflected between the blocking position and the release position by overcoming the spring force of the spring in the direction of the unlocked position, the sensor arrangement being designed to detect the locking slide located in the day position.

If only relatively small forces act on the wing in the day position of the bolt carriage, movement of the closure element from the blocking position into the release position is prevented and the wing is thus held conditionally in its closed position. If, on the other hand, relatively large forces act on the leaf when the bolt carriage is in the open position, this means that the closure element can move from a blocking position to its release position, as a result of which the bolt carriage can be deflected in the direction of its unlocked position by overcoming the spring force of the spring. In the day position of the bolt carriage, 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 when there are correspondingly large opening forces acting on the sash, without having to unlock the locking carriage beforehand.

A further embodiment of the invention provides that the control device is designed to move the bolt carriage into the blocking position or a holding position between the day position and the blocking position when the bolt carriage is in the day position and the closure element is moving into the blocking position and only after a predetermined period has elapsed period of time to return to the day position. In this way, an undesired jumping open of a thrown wing can be prevented.

The predetermined period of time is preferably at least 10 ms and at most 2 s. This means that it is preferable for the blocking position or holding position to be only for a short time approach so that there is no significant interruption of the day setting function.

A control device of the closure can be designed to move the bolt carriage into the blocked position only when the closure element is in the blocked position. This can prevent unwanted wedging of the components.

The closure element can have a closed position, with the blocking position being between the closed position and the release position, and with the bolt slide in its blocking position permitting movement of the closure element between its blocking position and its closed position. The sensor arrangement can be designed to differentiate between the blocking position, the release position and the closed position.

The bolt carriage can have a locking position, with the locking position being between the locking position and the unlocking position, with the locking carriage and the locking element interacting in a driving manner in such a way that the locking element assumes the locking position when the locking carriage moves from its locking position into its locking position, and wherein the Sensor arrangement is designed to detect the locking carriage located in the locking position.

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

A restoring spring can be provided, by which the closure element is prestressed 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 defines a holding receptacle for a locking element fastened to the leaf or to the frame and can be moved between a release position releasing the locking element in an opening direction of the leaf and a blocking position blocking the locking element in the opening direction. wherein the closure element can be moved automatically from the release position in the direction of the blocking position when the closure is mounted by a closing movement of the wing, and a blocking element which can be moved between a blocking position and an unlocked position, wherein the blocking element in the blocking position causes a movement of the closure element from the blocking position into the release position prevents and in the unlocked position allows a movement of the closure element between the blocking position and the release position, the closure having a motor for driving the Blocking element and a control device for activating the motor, and wherein the control device is designed to set the blocking element into the blocking position upon movement of the closure element into the blocking position and, after a predetermined period of time, back towards the unlocked position. As a result, an undesired jumping open of a thrown wing can be prevented.

The invention also relates to a window, a door or the like with a frame, a sash that can be moved relative to the frame, and at least one lock for releasably fixing the sash to 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 the sash. Further configurations can be found in the dependent claims, the description and the attached drawings.

the 1 shows a top view of a closure 10 according to the invention, which has an elongate base body 12 which accommodates the individual components of the closure 10 and thus serves as a type of housing. In particular, the base body 12 has two opposite side walls 13 running in the longitudinal direction of the base body 12, between which the individual components of the closure 10, which are described in more detail below, are arranged. Like that one in particular 6 can be removed, the base body 12 has a relatively small width and depth and can thus be mounted in a fitting groove of a wing to be secured by means of the closure 10 .

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

On the side opposite the holding receptacle 16 , the closure element 14 has a toothing 17 which meshes with a toothing 18 which is formed on a gear element 19 which is pivotably mounted on the base body 12 about a pivot axis 11 . On the side opposite the toothing 18, the gear element 19 forms a projection 20, also referred to here as a sliding cam, the function of which will be discussed in more detail below.

Furthermore, the closure 10 has a locking carriage 21 that can be moved in the longitudinal direction of the same, which forms a locking cam 22 on the side facing the gear element 19, which interacts with the sliding cam 20, as will also be explained in more detail below.

Furthermore, the closure 10 has an electric motor 23 which is arranged on the base body 12 and which is coupled to the bolt carriage 21 in a drivingly effective manner in such a way that it can move in different directions depending on the direction of rotation of the motor 23 . More precisely, the motor 23 drives a drive spindle 24 of a spindle drive 25 ( 2 ), wherein the rotation of the drive spindle 24 causes a spindle nut 26 arranged thereon to be moved in the longitudinal direction of the drive spindle 24 in a manner known per se. The bolt carriage 21 is supported on the spindle nut 26 so that it can be moved in different directions together with the spindle nut 26 depending on the direction of rotation of the drive spindle 24 .

To supply energy to the electric motor 23, the closure 10 has an energy store such as a battery and/or an induction coil, which is not shown in the figures. The electric motor 23 could also be supplied with energy by wire.

Once again 1 can again be removed, the locking carriage 21 is supported by two springs 28 on the spindle nut 26, so that the locking carriage 21 can be deflected against the spring force of the springs 28 when the spindle nut 26 is stationary. On the other hand, when the bolt carriage 21 is stationary, the spindle nut 26 can be moved relative to the same. However, the relative mobility between the spindle nut 26 and the locking carriage 21 is limited by two stops (not visible) spaced apart from one another in the axial direction of the drive spindle, so that the locking carriage 21 can be taken along by the spindle nut 26 after the respective stop has been reached.

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

Since the closure element 14 and the gear element 19 mesh with one another via the two toothings 17, 18, the gear element 19 is pivoted in the counterclockwise direction. This pivoting movement of the closure element 14 and the gear element 19 is in the in 1 The position shown is therefore possible because the bolt carriage 21 is in its unlocked position E, which it assumes when it has been pulled in the direction of the electric motor 23 by means of the spindle drive 25 . In this unlocked position E, the sliding cam 20 of the gear element 19 cannot collide with the locking cam 22 of the locking carriage 21, which is why the closure element 14 can be pivoted freely in the manner described above.

The closure element 14 is biased in the direction of its release position F by means of a restoring spring, not shown here, with this spring being able to act either directly on the closure element 14 or on the gear element 19 and thus indirectly on the closure element 14 .

If the closure element 14 according to the above statements 1 starting from the release position F shown in the 4 Blocking position B shown has been pivoted, a movement of the closure element 14 can be prevented back into its release position F by the bolt carriage 21, as is shown in FIG 4 is shown. In the 4 is the bolt carriage 21 in its locked position S, in which it is elastically urged by the springs 28. In this blocking position S, the locking cam 22 of the locking carriage 21 engages behind the sliding cam 20 of the gear element 19 in such a way that a movement of the closure element 14 from its in the 4 shown blocking position B back to its release position F is prevented.

Alternatively, however, it is also possible to advance the bolt carriage 21 by energizing the motor 23 by means of the spindle drive 25 in the 2 into the waiting position W shown, in which the locking cam 22 is in contact with a convex sliding surface section of the sliding cam 20 on the front side or touches it, the locking carriage 21 being elastically pretensioned in this waiting position W by means of the springs 28 against the sliding cam 20.

If in this waiting position W of the bolt carriage 21, the closure element 14 from the illustrated release position F in its blocking position B according to 4 pivoted, the sliding cam 20 slides with its convex counter-sliding surface 30 along the end face of the locking cam 22, whereby the locking carriage 21 is elastically deflected in the direction of its unlocked position E against the biasing force of the springs 28. As soon as that Closure element 14 has reached its blocking position B and as a result the slide cam 20 has moved counterclockwise past the locking cam 22, the locking carriage 21 is pushed beyond its waiting position W by the prestressing force of the springs 28 into its locking position S, in which the locking cam 22 according to the sliding cam 20 4 engages behind, whereby the closure element 14 is secured in the blocking position B shown.

In order to be able to secure the closure element 14 in its blocking position B as part of the daytime function against low opening forces, whereas the closure element 14 should be able to be pivoted back from the blocking position B back into its release position F in the event of larger opening forces, the bolt carriage 21 has between the 4 shown blocking position S and in the 1 unlocked position E shown here as a day position T designated intermediate position, as in the 3 is shown. In this day position T, the bolt carriage 21 has the same relative position with respect to the spindle nut 26 as in the locked position ( 4 ) on; however, the bolt carriage 21 was pulled back a little in the direction of its unlocked position E by means of the spindle drive 25 or the spindle nut 26, as can be seen from a comparison of the respective positions of the bolt carriage 21 according to FIG 3 and 4 emerges.

In the daytime according to 3 the sliding cam 20 rests against a sliding surface 31 of the locking cam 22, this sliding surface 31 forming a ramp or being inclined like a ramp in such a way that the locking carriage 21 is deflected in the direction of its unlocking position E against the spring force of the springs 28 when the sliding cam 20 is pivoted due to a pivoting movement of the closure element 14 counterclockwise in the direction of its release position F in the clockwise direction. So if the opening force on the closure element 14 is sufficiently large, this means that the bolt carriage 21 against the holding resistance of the springs 28 in the direction of its Unlocked position E is deflected and thus the movement of the closure element 14 and the closure element 19 releases. The sliding cam 20 moves partially past the locking cam 22 in a clockwise direction and slides along the end face of the same.

During this sequence of movements, the gear element 19 is initially subjected to a counterclockwise torque by the bolt carriage 21; due to the convex shape of the counter-sliding surface 30 of the sliding cam 20, this counter-clockwise torque decreases with increasing clockwise rotation of the gear element 19, until it then increases again, but then clockwise. This variation of the torque, which the gear element 19 experiences through the bolt carriage 21 due to the spring preload by the springs 28, causes the closure element 14 to snap over, so that the closure element 14 has two defined end positions in the unlocked position T of the bolt carriage 21, namely the release position F on the one hand and the blocking position B on the other.

Since the sliding cam 20 is in the release position F of the closure element 14 with its counter-sliding surface 30 against the end face of the locking cam 22, the closure element 14 can then be pivoted back into its blocking position B against the resistance applied by the springs 28, in which it is in the Day position T of the bolt carriage 21 is secured conditionally. In the day position T of the bolt carriage 21, it can thus be deflected in the direction of its unlocked position E as a result of a movement of the closure element 14 against the spring force of the springs 28.

The blocking position B of the closure element 14 is angularly oriented in such a way that the sash does not lie tightly against the frame, so that a certain amount of gap ventilation is still possible. However, starting from the release position F, the closure element 14 can move beyond the blocking position B into an in figure 5 shown Closed position SS are pivoted so as to clamp the wing tightly to the frame.

For this purpose, the bolt carriage 21 is based on the in the 4 blocking position S shown by means of the spindle drive 25 proceed further in the direction of the gear element 19 or the closure element 14 . The spindle nut 26 is first moved in the direction of the bolt carriage 21 until the spindle nut 26 abuts the bolt carriage 21, so that the latter is moved from its blocked position S towards its locked position V as the spindle nut 26 continues to move. During this movement sequence, the sliding cam 20 continues to ride on the sliding surface 31 of the locking cam 22, with the result that the gear element 19 is pivoted further counterclockwise. The closure element 14 is thus pivoted clockwise into its closed position SS, as a result of which the leaf is pulled firmly against the frame. Since the distance between the point at which the sliding surface 31 of the locking cam 22 is in contact with the sliding cam 20 and the pivot axis 11 of the gear element 19 is greater than the distance between the pivot axis 11 of the gear element 19 and the power transmission point between the teeth 17, 18, the gear element 19 acts as a reduction gear. However, the gear element 19 can equally be replaced by a two-armed lever with lever arms of different lengths.

If the wings are opened again, the bolt carriage 21 is at least temporarily back in its in the 1 shown unlocking position E moves, in which the bolt carriage 21 allows that the closure element 14 can swing back into its release position F by the restoring spring acting either on the closure element 14 or on the gear element 19 .

In the embodiment described above, the closure element 14 is pulled in the direction of its closed position SS in that the sliding cam 20 is deflected by the ramp-shaped sliding surface 31 of the locking cam 22 when the locking carriage 21 is moved towards its locking position V.

As an alternative to this, the transmission element 19 can be coupled to the locking carriage 21 via a toggle lever mechanism, which develops its effect of deflecting the closure element 14 in the direction of its closed position SS when the locking carriage 21 is moved into its locking position V. This toggle mechanism includes according to 7 and 8th a coupling lever 32 which is articulated on the one hand on the locking carriage 21, in particular on its locking cam 22, and on the other hand on the gear element 19, in particular on its sliding cam 20. The articulation point at which the coupling lever 32 is articulated on the bolt carriage 21 is formed by a pivot pin 33 which is displaceably mounted in a slot 34 formed in the bolt carriage 21 . This slot guide 33, 34 allows in the tag position T of the bolt carriage 21 a deflection of the same in the direction of its unlocked position E, as is required, among other things, to implement the tag function.

If the spindle nut 26 starting from the in the 7 If the position shown is moved in the direction of the bolt carriage 21, it comes into contact with the bolt carriage 21, whereupon this is carried along by the spindle nut 26. With continued movement of the spindle nut 26, the pivot pin 33 then comes into contact with the end of the elongated hole 34 which faces the spindle nut 26, whereupon with continued movement of the spindle nut 26 the coupling lever 32 pivots clockwise about its pivot point on the gear element 19 with the result is that the dimension measured transversely to the direction of movement of the bolt carriage 21 between the two pivot points of the coupling lever 32 increases. This in turn has the consequence that the gear element 19 pivots counterclockwise and thus the Closure element 14 is pivoted clockwise towards its closed position SS, see also the 8 .

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

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

In the individual representation in the lower part of the figure, the positions of the permanent magnets 57B, 57C, 57D shown correspond to the positions of the gear element 19, the locking slide 21 and the spindle nut 26 shown in the upper part of the figure. It should be pointed out that the scale of the representation of the sensor arrangement 50 in lower part of the figure is stretched compared to the representation of the closure 10 in the upper part of the figure, so the positions of the Hall sensors 55B-H and the permanent magnets 57B-D in the individual parts of the figure do not correspond exactly. The permanent magnet 57A applied to the locking element 60 and the associated, in 1 furthest left Hall sensor 55A are omitted in the individual representations and for the sake of simplicity only in the upper part of the figure 1 shown.

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

The second Hall sensor 55B, seen from the left, interacts with a permanent magnet 57B which is applied to the gear element 19. If the gear element 19 moves as in 1 is in the release position F as shown, the permanent magnet 57B is out of the detection range of the Hall sensor 55B, so that the Hall sensor 55B outputs a negative detection signal. If, on the other hand, the gear element 19 moves as in 3 and 4 shown in the blocking position B, the permanent magnet 57B is in the detection range of the Hall sensor 55B, so that it outputs a positive detection signal. The Hall sensor 55B can thus be used to determine whether the closure element 14 is in the blocking position B or in the release position F.

The third Hall sensor 55C, viewed from the left, interacts with a permanent magnet 57C that is mounted on the locking carriage 21. When the bolt carriage 21 moves as in 1 shown in the unlocked position E or as in 2 is at the waiting position W as shown, the permanent magnet 57C is out of the detection range of the Hall sensor 55C, so that the Hall sensor 55C outputs a negative detection signal. If, on the other hand, the bolt carriage 21 moves as in 4 shown in the locked position S or as in figure 5 shown in the locked position V, the permanent magnet 57C is in the detection range of the Hall sensor 55C, so that it outputs a positive detection signal. If the bolt carriage 21 moves as in 3 shown is in the day position T, the permanent magnet 57C already overlaps with the detection range of the Hall sensor 55C, so that this is also a positive one in this case outputs detection signal. The Hall sensor 55C can therefore be used to determine in particular whether the locking slide 21 is in the locked position S or in the unlocked position E. By providing a further Hall sensor or providing sufficient spatial resolution, a distinction could also be made between the unlocked position E, the waiting position W, the day position T, the locked position S and the locked position V, if required.

The remaining Hall sensors 55D-H interact with a permanent magnet 57D which is attached to the spindle nut 26. The Hall sensors 55D-H can be used to distinguish between five different positions of the spindle nut 26, which are Figures 1-5 , 7 and 8th viewed from right to left as the first open position O1, second open position O2, locking position A, first closed position G1 and second closed position G2. 1 shows the spindle nut 26 in the first open position O1, 2 in the second open position O2, 3 in the locked position A, 4 in the first closed position G1 and figure 5 in the second closed position G2.

An electronic evaluation device that is housed in the base body 12 and cannot be seen in the figures is connected to the Hall sensors 55A-H and is designed to receive detection signals output by them and to generate a status signal based on a comparison of the detection signals with the respective default values , which indicates the current functional status of the closure 10. The status signal is output to an electronic control device, not shown, which is connected to the motor 23 and to the evaluation device. The electronic control device is designed to control the motor 23 as a function of the status signal.

In particular, the electronic control device is designed to place the closure element 14 in the release position F when a handle or an "open" command is received from a higher-level controller, or if the closure element 14 is moved in the direction of the blocking position B and no locking element 60 is detected on the base body 12. In the latter case, an undesired malfunction state can be assumed, which can be remedied by opening the closure 10 .

Furthermore, the electronic control device is designed to move the locking carriage 21 automatically from the unlocked position E to the day position T or to the locked position S after detection of the blocking position B of the closure element 14 and the locking element 60 in the holding receptacle 16 in order to to hold the sash to the frame.

In order to prevent the wing from springing open again in the day position T of the bolt carriage 21 after it was thrown shut with momentum, it can also be provided that when it is determined that the closure element 14 has been pivoted from its release position F into its blocking position B , the locking carriage 21 is temporarily transferred in the direction of its locked position S into a temporary holding position in which it cannot be pushed back in the direction of its unlocked position E by the sliding cam 20 of the gear element 19 . However, this temporary holding position is only approached for a short time in order to prevent the sash from jumping open. Thereafter, the bolt carriage 21 can be moved back into its day position T.

It goes without saying that the sensor arrangement 50 can also include sensors which output position value signals instead of detection signals. In addition, the sensor arrangement 50 can include additional sensors in order to enable further distinctions between individual functional states of the closure 10 .
