Description

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

Such a closing device in the form of a building window comprises a cover element for covering the building opening, which can be tilted in a force-actuated manner in at least one adjustment movement between a closed position and at least one open position.

The locking device is designed as a window of a building. Correspondingly, the cover element is a window sash which is mounted on a frame in a tiltable manner.

For example, at least one electromotive actuator can be provided for the power-operated adjustment of the cover element. Such an electromotive actuator can e.g. be controlled by a control device as part of a system for building automation in order to open or close a building window, for example, depending on signals (e.g. via smartphone) transmitted remotely, pre-programmed times of day and / or environmental data recorded by sensors.

The basic problem with such a locking device is that an object, such as e.g. a body part of a person or an object which gets into an adjustment range of the cover element can collide with the cover element when it is actuated by force. This can result in injury to the person or damage to the object and / or the locking device.

In the US 2004/0140782 A1 a sensor is arranged on the inside and outside of a swivel wing of a building door, by means of which areas in front of and behind the swivel wing are monitored. In addition, a sensor can be arranged above the door.

The DE 10 2008 044 990 A1 describes a method and a device for controlling and / or monitoring a motor-driven wing, in which sensors for monitoring the adjustment movement are arranged on the wing or on a wall.

The object of the present invention is to provide a locking device with a power-operated adjustable cover element, in which it is reliably avoided that the cover element collides with an object during its adjustment movement.

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

Accordingly, a locking device of the type mentioned initially includes a security 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. The locking device is designed to stop and / or prevent the at least one adjustment movement of the cover element depending on the presence of an object in the detection area detected 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 is detected in a detection area. In this case, a radiation curtain makes it possible to detect the presence of an object in the detection area without contact, whereupon the switch-off function or the switch-on-prevention function for adjusting the cover element is actuated.

The at least one adjustment movement of the cover element takes place over an adjustment area, the adjustment area lying between the building opening and the detection area. For example, the detection area is arranged in front of a building window, which can be tilted in a power-operated manner over an adjustment area toward an interior. The radiation curtain extends between opposite sides of a window reveal, so that a person who reaches into the adjustment area of the window is forced to 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. The radiation curtain can thus be made invisible to the human eye and can be made safe in terms of energy. This allows the radiation curtain to be integrated safely and with little disruption into a building opening.

In one embodiment, the securing 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. As an alternative to this, 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. The radiation curtain can be formed between the transmitting device and the receiving device on the one hand and a reflection section for reflecting the radiation on the other hand. In a variant, the at least one transmitting device and the at least one receiving device can 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 beam entrance of the radiation from the at least one transmitting device to the at least one receiving device. For example, the object can scatter and / or absorb at least part of the radiation, so that the receiving device receives radiation of lower intensity as a result of the presence of the object. For example, an evaluation logic of the security device can evaluate such a decrease in the received radiation intensity that an object is located in the detection area.

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

The security device can, in particular, be designed to transmit a signal to the control device as a function of the presence of an object in the detection area detected by the radiation curtain. The control device can be designed to stop and / or prevent the at least one adjustment movement of the cover element depending on the signal transmitted by the safety device. For example, an evaluation logic of the security device can transmit a control signal to the control device after detecting the presence of an object in the detection area, 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 locking device according to the invention is provided. In particular, it can be provided that the cover element is adjustable in at least one first tilting movement from the closed position into at least one first open position and in at least one first lifting movement and / or at least one first combined lifting and tilting movement from the at least one first open position into at least one second open position is adjustable. By lifting the cover element from the first open position into the second open position, an additional gap in the building opening can be released below the cover element, which can advantageously lead to improved ventilation of an interior space. Opening the additional gap below the cover element basically opens up a potential risk of injury by pinching a human hand in the gap. Thus, the provision of the safety device according to the invention is particularly advantageous in this arrangement.

In a further development it is further provided that the cover element can be adjusted in at least one second tilting movement from the second open position into at least one third open position and in at least one second lifting movement and / or at least one second combined lifting and tilting movement from the at least one third open position in at least one a fourth open position is adjustable. Thus, additional open positions are advantageously available, which allow a particularly targeted adjustment of the cover element according to the current requirements with a view to optimal ventilation of the interior. The second The lifting movement ensures particularly good ventilation and / or ventilation, even in an area below the cover element.

The object is also achieved by a method having the features of claim 10 for operating a locking device according to the invention for a building opening. The above-described variants and advantages of a locking device according to the invention accordingly also characterize the method according to the invention for operating such a device, and conversely the following explanations of the method characterize the locking device.

In the method according to the invention, the cover element is force-operated during the at least one adjustment 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 element. The radiation curtain is generated at least during the adjustment of the cover element, and the at least one adjustment movement is stopped and / or prevented depending on the presence of an object in the detection area detected by the radiation curtain.

In an advantageous embodiment, the radiation curtain is switched on before or simultaneously with the adjustment of the cover element. Alternatively, however, it can also be provided that the radiation curtain is permanent, i.e. even if the cover element is not adjusted, is switched on. This can be particularly advantageous if the radiation curtain is used as part of an alarm system.

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

In one embodiment of the method according to the invention, the cover element is moved in the at least one power-operated adjustment movement in at least one first tilting movement from the closed position into at least one first open position and in at least one first lifting movement and / or at least one first combined lifting and tilting movement from the at least one first open position adjusts at least one second open position.

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

As already explained above with reference to the locking device according to the invention, additional open positions of the cover element are advantageously achieved in this way, which enable a particularly targeted adjustment of the cover element in accordance with the current requirements with a view to optimum ventilation of the interior .

The idea on which the invention is based will be explained in more detail below with reference to the exemplary 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 a further locking device with further possible open positions.

The Figure 1 shows a locking device 1 in the form of a building window 1. The cover element 10 for the window opening is formed by a window element 10 which comprises a window pane with a frame. The window element 10 is pivotally mounted on a window frame in such a way that it can be tilted out of 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 can be used, for example, as part of a system for building automation from a control device are controlled in order to adjust the window element 10, for example, as a function of signals (for example, via smartphone) transmitted remotely, preprogrammed times of day and / or environmental data recorded by sensors.
For example, the control device can be connected to an outside and / or inside temperature sensor. It is also conceivable that the control device receives signals from a rain sensor arranged on the outside of the window pane and processes them further.

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

In such a locking device 1, it can further be provided that a current position of the cover element 10 is shown on a display arranged in the area of the building window 1. Of course, a display of the current position of the cover element 10 on the display of a mobile device, such as of a smartphone or tablet PC possible.

The in the Figure 1 Shown locking device 1 further comprises a security 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 transmitter device 111 for emitting radiation in the direction of a lower window reveal (or a window sill) and at least one receiver device 112 for receiving the reflection section 113 emitted by the transmitter device 111 and reflected by a reflection section 113 arranged on the lower window reveal Radiation. The securing device 11 can thus generate a radiation curtain 110, which lies, for example, between an occupied interior space and an adjustment area V of the window element 10.

The radiation can in particular be electromagnetic radiation and preferably comprise infrared light and / or radio waves. Thus, the radiation curtain 110 can be made invisible to the human eye and can be made harmless in terms of energy, thereby enabling safe and less disruptive integration of the radiation curtain 110 on the building window 1.

For example, the transmitting device 111 can comprise a multiplicity of infrared light-emitting diodes, which are preferably arranged in a linear row on the upper window reveal, in order to produce an approximately continuous (infrared) light curtain which is located between the upper window reveal and the opposite lower window reveal ( or the windowsill).

The radiation curtain 110 thus defines a detection area D in which the presence of an object can be detected according to the principle of a light barrier known per se. For example, an object or a part of a person's body that enters the detection area D can scatter and / or absorb at least part of the radiation from the radiation curtain 110, so that the receiving device 112 subsequently receives radiation of comparatively 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 immediately stops or prevents the adjustment movement of the window frame 10.

Such an automatic switch-off function or switch-on prevention functions for the power-operated adjustment of the window frame 10 can reliably avoid an undesired 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 locking device 1 can thus be prevented.

The radiation curtain 110 can be switched on before or simultaneously with the adjustment of the cover element 10. Alternatively, however, it can also be provided that the radiation curtain 110 is permanent, i.e. even if the cover element 10 is not adjusted, is switched on. This can be particularly advantageous if the radiation curtain 110 is used as part of an alarm system. For example, evaluation logic of the security device 11 can output an alarm signal to a control device alarm system when the presence of an object is detected in the detection area D.

The Figure 2 shows a schematic view of a further embodiment of a locking device 1. The above explanations regarding the in Figure 1 shown Securing device 11 also meet the embodiment according to FIG Figure 2 to. In the Figure 2 However, in addition to the closed position S and the first open position O1, the closing device shown has further possible open positions O2, O4.

As already with reference to Figure 1 described, the cover element 10 can be adjusted in a first tilting movement from the closed position S into a first open position O1, so that a gap opens above and above the cover element 10 for ventilation and / or ventilation of the interior. In a first lifting movement and / or a first combined lifting and tilting movement, the cover element 10 can then be adjusted from the at least first open position O1 to at least one second open position O2. On the one hand, the gap above the cover element increases. On the other hand, when the cover element 10 is raised from the first open position O1 to the second open position O2 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 and tilting movement, the cover element in the form of the window element 10 can be moved, for example, by a height in the range between 1 cm and 2 cm, e.g. by 1.5 cm.

Opening the additional gap below the cover element basically opens up a potential risk of injury due to being pinched e.g. a human hand in the lower gap. The security device 11 according to the invention, which immediately stops the power-operated adjustment of the window element 10 when a person is present in the detection area D, can be used particularly advantageously on such a locking device 1.

In the embodiment according to Figure 2 The window element 10 can also be moved in a second tilting movement from the second open position O2 to a third open position O3 (not shown) and then in at least a second lifting movement and / or at least a second combined lifting and tilting movement from the third open position O3 to a fourth open position O4 will. Thus, additional open positions O3, O4 are advantageously available, which enable a particularly targeted adjustment of the cover element 10 in accordance with the respective requirements with a view to optimal ventilation and / or ventilation of the interior. The second stroke movement ensures particularly good ventilation an area below the cover element 10, since the lower gap, which forms a lower ventilation opening, is thereby enlarged.

In the second lifting movement and / or in the first combined lifting and tilting movement, the cover element in the form of the window element 10 can, for example, in comparison to its closed position S to a height in the range between 2 cm and 3 cm, e.g. to be raised to a height of 3 cm.

In addition to the described tilting movements, lifting movements or combined lifting-tilting movements, the closing devices 1 according to the Figures 1 and 2nd a rotation function of the window element 10 may be provided. The window element 10 can, for example, be rotated manually from its closed position S by 180 ° about a vertical axis. An outside of the window pane can thus be easily cleaned by a person located in the interior.
