Description

The present invention relates to an automatic window or door installation having a sash driven by a drive device and a sensor device arranged on a moving or a fixed component of the installation, in particular on the sash or window frame, for monitoring a range of movement of the sash in a contactless manner for obstacles such as persons or objects.An automatic window or door system of this type is known, for example, from DE 10 2018 214 215 A1. Moreover, an automatic door system having the features of the preamble of claim 1 in connection with a motor vehicle door is disclosed in DE 10 2019 103 249 A1.In the case of, for example, motor-driven windows which are installed below a height of 2.5 m, shearing and squeezing edges should preferably be secured. Various sensors and solution possibilities are known for this purpose. In the case of a window, for example, at least three closing edges should generally be secured. This often restricts the selection of sensors, or a plurality of sensors are required for this.It is an object of the invention to provide an automatic window or door system of the type mentioned at the beginning, in which the sensor device or the contactless monitoring of the range of movement of the sash operates particularly advantageously over as wide parts of the range of movement as possible and / or with as wide parts of the possible sash positions as possible.This object is achieved by an automatic window or door system having the features according to claim 1.It is thus possible that the sensor device or the contactless monitoring of the range of movement of the wing operates particularly advantageously and reliably over a particularly wide part of the range of movement and in the case of particularly many possible wing positions. In particular, the sensor device can be moved by the means such that, for example, a remaining range of movement is monitored as optimally as possible when closing the wing.The means can advantageously be designed in such a way that the sensor device is not visible when the wing is closed. As a result, the window or door system can be designed to be visually appealing and, in the closed state, the sensor device cannot leave a visually disturbing impression.In particular, the invention makes it possible to make the area monitored by the sensor device particularly small. Thus, the sensor device can be positioned or aligned advantageously with respect to the region to be monitored as a function of the closing movement and / or of a current position of the wing by the means. A small monitoring area makes it possible to minimize disturbing influences, such as, for example, those due to objects in the vicinity of but outside the movement area of the wing to be monitored, for example plants, paper stacks, a water bottle, or even reflections of a measurement signal on surrounding surfaces and / or objects.Furthermore, the invention makes it possible for the area monitored by the sensor device to remain at least substantially always assigned to a hazardous area. Reliable monitoring and thus advantageous protection of the installation are thus achieved.The monitoring serves in particular for detecting body parts and / or objects in the movement region of the wing, in particular in the region of at least one closing edge. The drive device is in particular configured to stop or reverse a closing movement if an obstacle, in particular a body part or an object, is detected in the movement region. Monitoring the range of movement and in particular closing edge monitoring serve, for example, to minimize the risk of injury to persons in the region of the wing. Thus, the drive device can be controlled to stop, for example, if a hand of a person is located in the range of movement of the wing and in particular between the wing and a frame during a closing process. In addition, the system as a whole and in particular the drive device is protected from damage by the wing being stopped if, for example, an object is located in its movement range, in particular between the wing and the frame, which could block a closing movement.The component on which the sensor device is arranged can be, for example, the wing, i.e. a moving component. Alternatively, the sensor device can be arranged, for example, on the frame, i.e., on a stationary component. The frame can preferably be a frame frame. In principle, a plurality of sensor devices can also be provided, for example at least one can be arranged on a fixed component and at least one on a moving component.According to one embodiment of the invention, it can be provided that the sensor device is arranged to move along on the wing, for example on a wing frame, or on a fixed component, namely a frame for the wing, a facade, a post-locking structure or on a fixed part of a drive device.According to yet another embodiment, it is provided that the means are configured to shift, rotate or pivot the sensor device when closing the wing in such a way that the region monitored by the sensor device moves, in particular shifts, rotates or pivots accordingly, in particular relative to the component. The orientation of the sensor device can thus be easily adapted according to requirements and in particular in a targeted manner according to the remaining range of movement during the closing movement.The system can also advantageously be configured to change the area monitored by the sensor device depending on a hazardous situation and / or a current hazardous location, in particular to adapt it mechanically, electrically and / or software-related to the respective hazardous situation or hazardous location.Furthermore advantageously, the system according to one embodiment of the invention can be configured to change the area monitored by the sensor device depending on a current position of the sensor device relative to the component and / or depending on a current position of the wing, in particular to adapt it mechanically, electrically and / or by software. This can improve the monitoring accuracy.The adaptation can comprise, for example, an adaptation with respect to an intensity of a measurement signal of the sensor device. In the case of a light-based sensor device, the monitored region can therefore be adapted with respect to the light intensity, for example. In particular, a detection threshold of the sensor device can be adapted.According to a further embodiment of the invention, the adaptation can alternatively or additionally comprise that at least one of a plurality of individual sensors, in particular pixels, of the sensor device is selectively switched on or off and / or is selectively evaluated or is not evaluated. The sensor device can preferably have an array of individual sensors or pixels. If the sensor device is moved when the wing is closed, in particular is moved into the component on which it is arranged, parts of the component or of the installation itself enter the monitoring region of the sensor device. During the movement, an edge of the component in question moves into the monitoring region, wherein initially only a small part of the monitoring region is covered or the edge initially only reaches a part of the monitoring region of the sensor device which is monitored by a subset of the individual sensors. These respective individual sensors, which are then therefore covered by the edge, can preferably be switched off for adaptation, wherein the remaining individual sensors, which are not yet covered by the respective edge, can remain active as long as they are not yet covered.A further development of the invention provides that the sensor device is designed to monitor the main closing edge and / or at least one secondary closing edge of the wing. In this context, one also refers to a closing edge monitoring. In particular, a monitoring of the main closing edge and of two secondary closing edges adjoining the main closing edge can be provided, for example by means of a single or a plurality of sensor devices.According to the invention, the sensor device has at least one transmitter element designed to emit a probe beam and a receiver element designed to detect the probe beam and / or to detect a reflection of the same. In this case, the transmitter element and the receiver element can preferably be arranged on the component.According to the invention, the term "beam" is not restricted to a permanently present measurement signal, but rather relates only to an at least substantially linear propagation direction thereof. Thus, a beam can in particular also comprise only one or more pulses which are in particular repeated regularly.Advantageously, it can also be provided that the transmitter element and the receiver element are arranged together in a sensor unit. This enables a particularly compact construction and simplifies the movement of the sensor device when closing the wing.According to the invention, the transmitter element is arranged and aligned such that the probe beam runs along a closing edge. According to a further development of the invention, it can be provided that the transmitter element is arranged and aligned such that the probe beam runs close to a closing edge. Preferably, the transmitter element can be arranged and oriented such that the probe beam runs both near and along a closing edge. In particular, the probe beam can be aligned at least substantially parallel to the closing edge.The sensor device can comprise, for example, a light-based sensor, preferably a laser and / or infrared sensor, in particular an active infrared sensor or a passive infrared sensor. Alternatively or additionally, the sensor device can also comprise a sound-based sensor, for example a sound generator and / or an ultrasonic sensor. Further alternatively or additionally, the sensor device can also comprise a sensor based on electromagnetic waves, for example an antenna. All these sensors are based on the evaluation of measurement signals. A measurement signal can be emitted by a transmitter element of the sensor device, in particular in the form of a probe beam, wherein the measurement signal is detected by means of a receiver element, for example directly or after a reflection on an obstacle. Alternatively or additionally, a measurement signal can also be emitted by an obstacle itself. Thus, the body of a person typically emits thermal radiation in the infrared range, which can be evaluated as a measurement signal by a receiver element. For example, a passive infrared sensor operates.Furthermore advantageously, the sensor device can be configured to measure a transit time, in particular directly or indirectly, an intensity and / or a Doppler shift of a measurement signal.An embodiment of the invention is particularly preferred in which the sensor device comprises a time-of-flight sensor. A time-of-flight sensor or ToF sensor for short is a sensor of this type, which has a transmitter element and a receiver element, which is not necessarily separate, in particular in a common sensor unit, wherein the transmitter element is configured to emit a probe beam and the receiver element is configured to detect the probe beam after reflection on an object, wherein a distance from the sensor device to the object can be determined on the basis of the travel time of the probe beam. ToF sensors are particularly compact and cost-effective and enable particularly precise monitoring of the movement range.It may be sufficient to install only one time-of-flight sensor or only a few time-of-flight sensors. In particular, in the case of a time-of-flight sensor, advantageously no spaced transmitter and receiver elements have to be provided on the wing, as is the case, for example, with light barriers. In addition, no additional components need to be provided, such as in reflex light barriers, in which a reflector has to be installed and adjusted.The time-of-flight sensor can advantageously be mounted in the interior. The sensor device is thus protected against weather influences. The time-of-flight sensor also makes it possible in a simple manner to ensure different window sizes using one and the same sensor. In particular, no mechanical length adaptation is required, such as in the case of switching strips. A time-of-flight sensor can also be constructed and arranged in a very space-saving manner. In addition, such a laser scanner does not have any mechanically moved parts, such as a laser scanner. As a result, the time-of-flight sensor is insensitive and durable.According to the invention, a plurality of sensor devices can also be provided, for example for monitoring different closing edges and / or different regions of closing edges. For example, two sensor devices may be arranged adjacent to each other and oriented in opposite directions.The means can comprise a mechanical mounting for the sensor device. Preferably, the means can be configured such that the sensor device is pushed into the component when the wing is closed, in particular such that the sensor device is not visible when the wing is closed. For example, the sensor device and / or a bearing for the latter can be prestressed against a stop by means of a spring and can be arranged in such a way that, when the leaf is closed, the sensor device is moved counter to the prestressing of the spring, in particular is displaced into a retracted position. The spring can also have the effect that the sensor device is moved out of the component again or pushed out when the wing opens. The stop can ensure that the sensor device does not move beyond a specific, in particular extended, relative position with respect to the component.In a preferred embodiment of the invention, the automatic window or door system comprises a hinged sash and / or forms, in particular, a hinged sash window. In particular, the flap can be a flap outward flap and / or a flap inward flap. In principle, however, the leaf can also be, for example, a rotating and / or tilting leaf and / or parallel display window.In order to avoid the sensor device having to be mounted in the outer area, it is advantageous, for example in the case of a folding outward leaf and a desired protection against engagement from the outside, to mount the sensor device in a manner moving along on the leaf. The sensor device can, however, also be advantageously mounted at another location in the inner region and / or on an inner side of the wing. As a result, the sensor device is protected against weather influences and manipulation from the outside.The invention is explained below merely by way of example with reference to the schematic drawings. FIG. 1 shows a window system according to the invention with a leaf, here with a hinged leaf window. FIGS. 2 and 3 show various embodiments according to the invention of mechanical bearings for the movable arrangement of a sensor device on a component of a window or door system. FIG. 4 shows a sensor device according to the invention with a plurality of individual sensors.The window system 10 schematically indicated in FIG. 1 comprises a leaf 12 which is designed as a hinged leaf. The wing 12 is arranged movably relative to a frame 14, namely a frame frame, and is driven for automatic movement via a drive device 16. The drive device 16 is arranged on the frame side and coupled to the wing 12 via a so-called wing bracket 17.When the wing 12 is automatically closed, it is important to detect obstacles such as objects and / or persons, in particular body parts of persons, in the movement range of the wing 12 in order to be able to automatically stop the closing movement of the wing 12. Therefore, a closing edge monitoring is provided, namely with a monitoring of a main closing edge 18 and of two secondary closing edges 19 adjoining the latter.For this purpose, the window system 10 comprises a sensor device 20, which is illustrated in FIGS. 2 and 3 in different embodiments in each case together with a mechanical bearing 22.An area 24 is also illustrated, which forms an area monitored by the sensor device 20. The sensor device 20 is arranged in such a way that the monitoring region 24 corresponds as largely as possible or at least partially to a movement region of the wing 12. The monitoring region 24 is shown substantially in the form of a fan. Accordingly, the sensor device 20 has a substantially fan-shaped monitoring region 24.The bearing 22 is movably arranged on a moving component, namely the wing 12, or alternatively on a fixed component, such as the frame 14. The sensor device 20 is arranged fixedly on the bearing 22 and moves with the bearing 22, The bearing 22 is arranged pre-tensioned on a first component, so that it is moved relative to the first component by a second component, namely pushed into the first component, when the wing 12 is closed. The first component is a moving component and the second component is a fixed component, or vice versa.FIGS. 2 and 3 illustrate, in a mutual comparison, a different arrangement of a sensor device 20 with respect to a bearing arrangement 22, and in both figures a direction of movement of the bearing arrangement 22 when the wing 12 is closed is indicated by an arrow 26. The movement of the bearing 22 relative to the component not shown in detail here corresponds to a rotation about an axis of rotation 28 indicated here by dashed lines. The monitoring region 24 is oriented at least substantially parallel in FIG. 2 and at least substantially perpendicular to an axis of rotation 28 of the bearing in FIG. 3. In both variants, the region 24 monitored by the sensor device 20 moves together with the bearing 22 and is pivoted about the axis of rotation 28.FIG. 4 shows a sensor device 20 having a plurality of individual sensors 30, which are each designed to emit a probe beam 32 and to detect a reflection of the probe beam 32 on an obstacle. The individual sensors 30 thus each comprise both a transmitter element and a receiver element, which are arranged in a common sensor unit. The individual sensors 30 are arranged in the form of an array and form so-called pixels of the sensor device 20.An object 34 is also indicated in FIG. 4. This is located in the monitoring region 24 and covers a part of the same or a subset of the individual sensors 30 or probe beams 32, respectively. the object 34 is the component on which the sensor device 20 is arranged, wherein the sensor device 20 is retracted into the component when the wing 12 is closed. The object 34 thus forms part of the wing 12 or frame 14, respectively. since the object 34 is not an obstacle to which the range of movement of the wing 12 is to be monitored, but is a part of the system 10, the operation of the two right individual sensors 30 is no longer necessary in the situation shown here. This situation is one which occurs during the closing operation. When the wing 12 is closed further, the further individual sensors 30 are gradually covered by the object 34.During the movement of the sensor device 20, an edge of the object 34 moves into the monitoring region 24, wherein initially only a small part of the monitoring region 24 is covered or the edge initially only reaches a part of the monitoring region 24 of the sensor device 20, which is monitored by a subset of the individual sensors 30. These respective individual sensors 30, which are then therefore covered by the edge--these being the right-hand two individual sensors 30 in FIG. 4--are switched off for adapting the monitoring region 24, the remaining individual sensors 30, which are not yet covered by the respective edge, remaining active as long as they are not yet covered.List of reference characters10 Window system 12 Sash 14 Frame 16 Drive device 17 Sash bracket 18 Main closing edge 19 Secondary closing edge 20 Sensor device 22 Mounting 24 Monitoring region 26 Movement 28 Axis of rotation 30 Individual sensor 32 Scanning beam 34 Object
