Description

The invention relates to a closing device for a building opening according to the preamble of claim 1 and to a method for operating a closing device for a building opening according to the preamble of claim 11.

Such a closing device comprises a cover for covering the building opening, which is power-operated adjustable in at least one adjusting movement between a closed position and at least one open position.

The locking device can be configured in particular as a window or as a door of a building. Accordingly, the cover element may be a window sash or a door sash which, for example, is mounted pivotably and / or tiltably on a frame.

For power-operated adjustment of the cover, for example, at least one electric motor actuator can be provided. Such an electromotive actuator can be controlled, for example, within the scope of a system for building automation by a control device, for example, depending on (eg by smartphone) remotely transmitted signals, pre-programmed times and / or recorded by sensors environmental data to open or close a building window.

In such a closure device, there is basically a problem that an object such a body part of a person or an object, which gets into an adjustment of the cover, the power-operated adjustment of the cover can collide with this. This can lead to injury to the person or damage to the object and / or the locking device.

Object of the present invention is to provide a closing device with a power-operated adjustable cover available, in which it is reliably avoided that the cover collides with its adjusting movement with an object.

This object is achieved by an article having the features of claim 1.

Accordingly, a closing device of the aforementioned type further comprises a securing device, which is designed to generate a radiation curtain in a detection area and to detect the presence of an object in the detection area by means of the radiation curtain. In this case, the closing device is designed to stop and / or prevent the at least one adjusting movement of the cover element as a function of a presence of an object detected in the detection area by means of the radiation curtain.

The present invention is based on the idea that an automatic switch-off function or a switch-on prevention function for the power-operated adjustment of the cover element can prevent an undesired collision with an object if the presence of the object in a detection area is detected. In this case, by means of a radiation curtain, a contactless detection of the presence of an object in the detection area is possible, after which the switch-off or the switch-on prevention function for the adjustment of the cover is actuated.

In a preferred embodiment, the at least one adjustment movement of the cover element can take place over at least one adjustment range, wherein the at least one adjustment region lies at least in sections between the building opening and the detection area. Thus, the detection area can be arranged, for example, in front of a building window, which can be tilted over an adjustment range to an interior in a power-operated manner. It is eg conceivable that the radiation curtain extends between opposite sides of a window reveal, so that a person who reaches into the adjustment of the window must inevitably reach through the radiation curtain.

The radiation curtain is preferably formed at least partially from electromagnetic radiation, in particular from radio waves and / or infrared light. Thus, the radiation curtain for the human eye can be made invisible and energetically harmless. This allows a safe and less disturbing integration of the radiation curtain at a building opening.

In one embodiment, the security device for generating the radiation curtain comprises at least one transmitting device for emitting radiation and at least one receiving device for receiving the radiation emitted by the transmitting device. For example, the radiation curtain can be formed between the at least one transmitting device and the at least one receiving device. Alternatively, however, it is also conceivable that at least one transmitting device and the at least one receiving device are arranged on one and the same side of the radiation curtain. In this case, the radiation curtain between the transmitting device and the receiving device on the one hand and a reflection portion for reflection of the radiation can be formed on the other hand. In a variant, the at least one transmitting device and the at least one receiving device may be part of an integrated transceiver device.

According to an advantageous embodiment, the detection of the presence of an object in the detection area by means of the radiation curtain comprises the detection of an at least partial interruption and / or obstruction of a radiation beam from the at least one transmission device to the at least one reception device. For example, the object may scatter and / or absorb at least a portion of the radiation such that the receiving device receives less intense radiation due to the presence of the object. For example, an evaluation logic of the security device can evaluate such a decrease in the received radiation intensity in such a way that an object is located in the detection area.

In one embodiment, the closing device comprises at least one actuator, such as an electric motor actuator for power-operated adjustment of the at least one cover element and a control device for controlling the at least one actuator.

The safety device may in particular be designed to transmit a signal to the control device as a function of a presence of an object detected in the detection area by means of the radiation curtain. In this case, the control device may be designed to stop and / or prevent the at least one adjusting movement of the cover element as a function of the signal transmitted by the securing device. For example, an evaluation logic of the security device, after detecting the presence of an object in the detection area, can transmit a control signal to the control device, whereupon the control device stops or prevents the at least one adjustment movement of the cover element.

According to a preferred variant, a multi-stage adjustability of the cover element of the closing device according to the invention is provided. In particular, it can be provided that the cover is adjustable in at least a first tilting movement from the closed position into at least a first open position and in at least a first stroke and / or at least a first combined stroke tilting movement of the at least one first open position in at least one second open position is adjustable. By lifting the cover from the first open position to the second open position, an additional gap of the building opening can be released below the cover, which can lead to an improved loading and / or ventilation of an interior in an advantageous manner. The opening of the additional gap below the cover element basically opens up a potential risk of injury by pinching a human hand in the gap. Thus, in this arrangement, the provision of the securing device according to the invention is particularly advantageous.

In a further development it is further provided that the cover is adjustable in at least a second tilting movement from the second open position to at least a third open position and in at least one second stroke movement and / or at least a second combined stroke-tilting movement from the at least one third open position in at least a fourth open position is adjustable. Thus, in an advantageous manner, additional open positions are available, which allow a particularly targeted adjustment of the cover according to the current requirements with a view to optimal loading and / or ventilation of the interior. The second Lifting motion ensures a particularly good loading and / or ventilation in a region below the cover.

The object is also achieved by a method having the features of claim 11 for operating a closing device according to the invention for a building opening. Accordingly, the above-described variants and advantages of a closing device according to the invention also characterize the method according to the invention for operating such a device, and vice versa, the following statements on the method characterize the closing device.

In the method according to the invention, the cover is force-actuated in the at least one adjusting movement between the closed position and the at least one open position and / or between the at least one open position and at least one further open position of the cover. In this case, the radiation curtain is generated at least during the adjustment of the cover, and the at least one adjustment is stopped and / or prevented depending on a detected by means of the radiation curtain presence of an object in the detection area.

In an advantageous embodiment of the radiation curtain is turned on before or at the same time with the adjustment of the cover. Alternatively, however, it may also be provided that the radiation curtain is permanently, i. even if the cover is not adjusted, is turned on. This can be advantageous in particular with an additional use of the radiation curtain as part of an alarm system.

Preferably, the presence of an object in the detection area is detected by the object at least partially interrupting and / or obstructing a beam path between a transmitting device for emitting radiation forming the radiation curtain and a receiving device for receiving the radiation.

In one embodiment of the method according to the invention, the cover element is displaced from the closed position into at least one first open position in at least one power-actuated adjusting movement in at least one first tilting movement and in at least one first lifting movement and / or at least one first combined stroke tilting movement of the at least one first open position adjusted at least a second open position.

According to a further development, it can further be provided that the cover element is displaced from the second open position into at least one third open position in at least one second tilting movement and in at least one second stroke movement and / or at least one second combined stroke tilt movement from the at least one third open position in FIG at least a fourth open position is adjusted.

As already explained above with reference to the closing device according to the invention, additional open positions of the cover element are advantageously realized in this way, which allow a particularly targeted adjustment of the cover according to the current requirements with a view to optimal loading and / or ventilation of the interior ,

The idea underlying the invention will be explained in more detail with reference to the embodiments illustrated in the figures. Show it:

Fig. 1

a schematic view of a locking device in the form of a building window in a closed position and a plurality of open positions; and

Fig. 2

a schematic view of another locking device with other possible open positions.

The FIG. 1 shows a closing device 1 in the form of a building window 1. In this case, the cover member 10 for the window opening is formed by a window member 10 which comprises a window pane with a framing. The window element 10 is pivotably mounted on a window frame in such a way that it can be tilted from a closed position S into a first open position O1 and into further open positions (shown with dashed lines).

For power-operated adjustment of the window element 10 between the closed position S and the first open position O1 or another open position or between the different open positions an actuator is provided, which preferably comprises an electric motor (not shown). The actuator may, for example, in the context of a system for building automation of a control device be controlled, for example, depending on (eg by smartphone) remotely transmitted signals, pre-programmed time of day and / or recorded by sensors environment data to adjust the window element 10.
For example, the control device may be connected to an outside and / or inside temperature sensor. It is also conceivable that the control device receives and processes signals from a rain sensor arranged on the outside of the window pane.

Furthermore, by means of the control device, a power-operated roller shutter can additionally be controlled, which is closed or opened, for example, as a function of a signal provided by a rain sensor.

In the case of such a closing device 1, it may further be provided that a momentary position of the covering element 10 is displayed on a display arranged in the region of the building window 1. Of course, an indication of the current position of the cover 10 is also shown on the display of a mobile device, such as a mobile device. of a smartphone or tablet PC conceivable.

The in the FIG. 1 Locking device 1 shown further comprises a securing device 11 with an integrated transceiver device 111, 112, which is arranged on an upper window reveal. The transceiver device 111, 112 comprises at least one transmitting device 111 for emitting radiation towards a lower window embrasure (or sill) and at least one receiving device 112 for receiving the reflection emanating from the transmitting device 111 and reflected by a reflection section 113 arranged at the lower window embrasure Radiation. Thus, the securing device 11 can generate a radiation curtain 110 which, for example, lies between an inhabited interior space and an adjustment area V of the window element 10.

The radiation may be in particular an electromagnetic radiation and preferably comprise infrared light and / or radio waves. Thus, the radiation curtain 110 can be invisible to the human eye and energetically harmless, whereby a safe and less disturbing integration of the radiation curtain 110 is made possible on the building window 1.

For example, the transmitting device 111 may comprise a plurality of infrared light emitting diodes, which are preferably arranged in a linear array on the upper window reveal, to produce an approximately continuous (infrared) light curtain which extends between the upper window reveal and the lower lower reveal (FIG. or the sill).

The radiation curtain 110 thus defines a detection area D, in which a presence of an object can be detected according to the principle known per se of a light barrier. For example, an object or body part of a person entering the detection area D may scatter and / or absorb at least a portion of the radiation of the radiation curtain 110, such that the receiving device 112 subsequently receives radiation of relatively lower intensity. Such a decrease in the received radiation intensity can then be evaluated by an evaluation logic of the security device 11 in such a way that an object is located in the detection area D. In this case, the evaluation logic can transmit a control signal to the control device in the actuator for the window element 10, whereupon the control device stops or prevents the adjustment movement of the window frame 10 immediately.

Such an automatic shut-off function for the power-operated adjustment of the window frame 10 can reliably prevent undesirable collision of the window frame 10 with an object such as a body part of a person or an object. Possible injuries to a person or damage to an object and / or the closing device 1 can thus be prevented.

The radiation curtain 110 can be switched on before or at the same time as the adjustment of the cover element 10. Alternatively, however, it may also be provided that the radiation curtain 110 be permanently, i. even if the cover 10 is not adjusted, is turned on. This can be advantageous in particular with an additional use of the radiation curtain 110 as part of an alarm system. Thus, for example, an evaluation logic of the security device 11 can output an alarm signal to a control device alarm system if the presence of an object in the detection area D is detected.

The FIG. 2 shows a schematic view of another embodiment of a closure device 1. The above explanations with respect to in FIG. 1 shown Safety device 11 apply analogously to the embodiment according to FIG. 2 to. In the FIG. 2 However, shown closing device has in addition to the closed position S and the first open position O1 further possible open positions 02, 04.

As already mentioned above with reference to FIG. 1 described, the cover 10 can be adjusted in a first tilting movement from the closed position S in a first open position O1, so that above the cover 10, a gap for loading and / or ventilation of the interior opens. In a first stroke movement and / or a first combined stroke-tilting movement, the cover element 10 can then be adjusted from the at least first open position O1 into at least one second open position 02. On the one hand, the gap above the cover element increases. On the other hand, by lifting the cover element 10 from the first open position O1 into the second open position 02 below the cover element 10, an additional gap opens, which can advantageously lead to improved ventilation of an interior, in particular by air circulation ,

During the first lifting movement and / or during the first combined lifting / tilting movement, the covering element in the form of the window element 10 may, for example, be at a height in the range between 1 cm and 2 cm, e.g. be raised by 1.5 cm.

The opening of the additional gap below the cover element basically opens up a potential risk of injury by pinching, e.g. a human hand in the lower gap. Thus, the securing device 11 according to the invention, which immediately stops the power-operated adjustment of the window element 10 in the presence of a person in the detection area D, can be used particularly advantageously on such a closing device 1.

In the embodiment according to FIG. 2 can the window member 10 further in the second tilting movement from the second open position 02 in a third open position 03 (not shown) and then adjusted at least a second stroke and / or at least a second combined stroke tilting movement from the third open position 03 into a fourth open position 04 become. Thus, in an advantageous manner, additional open positions 03, 04 are available, which enable a particularly targeted adjustment of the cover element 10 according to the respective requirements with a view to an optimal loading and / or ventilation of the interior. The second stroke ensures a particularly good loading and / or ventilation in an area below the cover member 10, since the lower gap forming a lower vent opening is thereby increased.

During the second stroke movement and / or during the first combined stroke-tilting movement, the cover element in the form of the window element 10 can be raised to a height in the range between 2 cm and 3 cm, for example compared to its closed position S. to be raised to a height of 3 cm.

In addition to the described tilting movements, lifting movements or combined lifting-tilting movements can in the closing devices 1 according to the FIGS. 1 and 2 a rotational function of the window member 10 may be provided. In this case, the window element 10, for example, manually rotated from its closed position S about a vertical axis by 180 °. Thus, an outside of the window pane can be conveniently cleaned by a person located in the interior.
