Description

The invention relates to a device for opening and / or closing a component which has at least one movable component. The device comprises a drive for the movable component, a safety device which comprises at least one sensor for monitoring a danger point in the area of the component during an opening and / or closing movement of the component caused by the drive, and a control device which is designed to in normal operation, to open and / or close the component by means of the drive, in particular automatically, and in the event of a fault, in particular a dangerous situation or an error detected by the sensor, to end the current opening and / or closing movement of the component or to reverse and / or to establish a safe state in which movement of the component is prevented by means of the drive.

Such devices are known in principle. The component is in particular a door or a window of a building. Accordingly, the movable component is in particular a turn, pivot or tilt sash or a door leaf.

In modern buildings, in particular, when the component is opened or closed automatically by means of the drive, potential danger spots in the area of the component are mostly monitored by means of one or more sensors. In the case of a window or a door, the closing edges in particular represent such potential danger spots. Sensors known in practice, for example, operate without contact, e.g. in the case of light switches, light grids or ultrasonic sensors, with tactile sensors such as switching strips or switching mats also being used as an alternative.

An automatic opening or closing or an automatic drive of the component is understood here to mean that after activation of the drive - which can also take place manually, i.e. not automatically - the drive carries out the respective movement process of the component, i.e. opening or closing , automatically leads to the end, that is to say continues until a defined end state is reached, which is in particular the intended open or closed position of the component.

The safeguarding of a danger point by a safety device typically consists in the fact that the drive for the movable component stops or reverses the movement of the component (i.e. reverses) if a sensor of the safety device responds during a potentially dangerous movement of the component. This is the case, for example, if a person or an object intervenes in the monitoring area of a non-contact sensor or e.g. a pressure sensor is acted upon mechanically. When the safety device releases the movable component again, normal operation can be resumed, in which the component can be opened or closed by means of the drive.

Known safety devices are often provided with a self-test function or another possibility for functional testing, which makes it possible, in particular, to monitor the correct function of the sensors. If an error is detected, a change is made to a safe state. In practice, however, automatic function tests do not only take place in connection with the safety device, but also with the drive or its control. As soon as an error in the drive or in the control device is detected, a safe state is also established.

Such safe states are characterized, among other things, by the fact that the movable component is stationary. Movement of the component by the control device is prevented in such a safe state, since proper functioning of the safety device or the components connected to it is no longer guaranteed, so that dangerous situations are avoided by establishing the safe state.

The disadvantage of such a situation is that the entire device is only put back into a proper state, i.e. the safe state must be canceled in order to be able to move the component by means of the drive. The users or residents of a building, so to speak the “staff on site”, are often neither able nor authorized to do this. It is therefore necessary to wait for external service personnel until the component is moved again, for example a window or door can be closed. This situation is often extremely unsatisfactory because, for example, if the door is left unlocked for a long time, building security cannot be guaranteed or a building management system cannot ensure proper air conditioning of the building.

In some cases it is possible to close or open the door or window manually. However, this is not possible, for example, if the drive for the moving component is provided with a self-locking gear. This is particularly the case with the spindle drives that are frequently used in practice. For other reasons it may be impossible to remove the component to move manually without damaging the drive or other components of the overall arrangement.

In practice, situations often arise in which, due to an error, a change is made to a safe state and a dangerous situation is avoided, but an affected window or a door, for example, cannot be closed for a longer period of time.

The object of the invention is to provide a remedy and thus a possibility of being able to move a component that cannot or should not be moved manually, even in the event of a fault, without, however, endangering safety.

This object is achieved in each case by the features of the independent claims.

In the device according to the invention with the features of claim 1, an emergency operating device is provided for emergency operation, which comprises at least one actuating member to be acted upon by a user and is designed to cause the drive to open or close the component when the actuating member is acted upon causes.

The emergency operating device according to the invention allows people on site, ie in particular the users or residents of the respective building, to move the component by means of the drive. As a result, the user does not have to wait for service personnel to be able to lock the building, for example. By providing an actuating member to be acted upon by a user, the invention pursues the concept of actively involving a user in emergency operation. This has the advantage that the user initiating the emergency operation can take care of the safety which the safety device takes care of in normal operation.

Advantageous embodiments of the invention are also specified in the following description, in the claims and in the drawing.

The emergency operating device preferably operates according to the so-called dead man principle, i.e. emergency operation takes place in accordance with dead man operation. This means that the user has to become and remain active in order to initiate and maintain the opening and closing movement of the component.

It is preferably provided that the drive is only activated when the actuating element is acted upon and the drive stops when the actuating element is no longer acted upon.

The user must consequently ensure that the actuation element is maintained as long as the drive is to remain activated in order to move the component in the respectively desired direction, either in the opening direction or in the closing direction.

It is preferably provided that the actuator is to be actuated manually by the user. An immediate operation by the user is therefore required. Acting that is conceivable in principle and taking place in another way, for example by means of an app on a mobile phone or a tablet, is excluded here.

In some exemplary embodiments, it is provided that the actuating element is a button or a button which is to be pressed by the user and which automatically returns to the starting position after it is released.

It is preferably provided that emergency operation is only possible in the event of an error, in particular an error in the drive, an error in the safety device and / or an error in the control device, and a resulting safe state, but not in the event of a dangerous situation detected by the sensor device or in normal operation. This prevents an unnecessary movement of the component from being accidentally triggered by actuating the emergency operating device.

The emergency operating device can either be ready for operation at any time or only in the event of a fault. Consequently, the device as a whole can be designed in such a way that the emergency operating device is automatically put into an operational state only in the event of a fault.

The emergency operating device can be connected to the drive either directly or via the control device.

In some exemplary embodiments, the emergency operating device is connected to the sensor. If the safety device has several sensors, it can be provided that the emergency operating device is only connected to one of the sensors.

The control device can be integrated in the sensor or - if several sensors are present - in one of the sensors of the safety device.

In some exemplary embodiments, it is provided that the emergency operating device is integrated in the safety device, in particular in its sensor. The sensor and the emergency operating device can have a common housing.

In alternative embodiments of the invention, the emergency operating device is a unit that is separate from the safety device, in particular from its sensor. It can then be provided here that the sensor of the safety device and the emergency operating device have their own separate housings.

The emergency operating device can comprise only one actuator for opening the component or only one actuator for closing the component or two actuators, one of which is provided for opening the component and the other for closing the component.

In some exemplary embodiments, the drive for the movable component has at least one electric drive motor and a self-locking gear. The drive motor is for example a servo motor and the gearbox is e.g. around a spindle drive consisting of a spindle nut connected to the movable component and a spindle that can be set in rotation by means of the motor. In general, however, the type of motor drive for the movable component is arbitrary.

The sensor of the sensor device can be a contactless sensor or a tactile sensor.

The invention also relates to a door and / or window arrangement with at least one rotary, pivot or tilt sash and / or door leaf as a movable component, and with at least one device for opening and / or closing as disclosed herein.

Furthermore, the invention relates to a safety device for a device for opening and / or closing as disclosed herein, wherein the safety device comprises at least one sensor for monitoring the danger point, and wherein the emergency operating device is integrated in the sensor or the emergency operating device is provided separately from the sensor.

The invention also relates to a method for operating a device for opening and / or closing as disclosed herein or for operating a door and / or window arrangement as disclosed herein, with the method in normal operation using the drive, in particular automatically, based on a Signal to the control device is opened or closed, in the event of a malfunction due to an error, the drive is automatically stopped and a safe state is established, and when the safe state is established in emergency operation, the drive is activated to open and / or open by means of the drive To effect closing movement of the component when the actuator of the emergency operating device is acted upon by a user.

In this method it is preferably provided that in emergency operation the drive is automatically stopped when the actuating element is no longer acted upon by the user. In other words, the emergency operation takes place according to the dead man principle already mentioned above.

• 3 schematisch ein alternatives Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung.

The invention is described in the following purely by way of example using exemplary embodiments with reference to the drawing. These merely represent possible embodiments of the invention, further embodiments being evident from the description and the claims. Show it:

• 1 schematically a window arrangement according to the invention with a device according to the invention for opening and closing a window sash according to an embodiment of the invention,
• 2 schematically an embodiment of a device according to the invention, and
• 3 schematically an alternative embodiment of a device according to the invention.

1 shows schematically a window arrangement according to the invention as a component 11 who have favourited a frame 31 and a tilt vane 13 having relative to the frame 31 is pivotable between a closed position and an open, tilted position.

These movements of the wing 13 to open and close the window 11 take place by means of a drive 15th , which has a controllable electric drive motor and a self-locking gear and in a manner not shown here with the wing 13 is mechanically connected. The opening and closing of the wing 13 occurs automatically when the drive 15th a corresponding signal from a control device 19th receives.

At the control device 19th For example, it can be a central building management system or one only in the area of the window 11 Act attached control device, which includes, for example, a button to be actuated by a user, via which the drive 15th is controlled, for example, to open the Wing 13 for the purpose of ventilating the respective room.

The lateral closing edges of such a window 11 represent potential danger spots. In order to monitor these danger spots, a safety device is provided, which in the present example has two sensors 17th includes in the form of light buttons. The sensors 17th are with the drive 15th connected.

When in a normal operation in which the wing 13 by means of the drive 15th for example is moved in the closing direction to the window 11 to close one of the sensors 17th responds due to an intervention in its monitoring area 35, the drive 15th stopped to move the wing 13 to prevent. Alternatively, the movement is not stopped but reversed, ie the wing 13 moved in opening direction. As soon as there is no longer any intervention in the monitoring area 35 and the safety device closes the wing 13 consequently releases again, the originally desired automatic closing process can continue or be carried out again.

If, however, no dangerous situation but an error condition is detected, the current opening or closing movement of the sash is activated 13 although also stopped. However, there is no automatic resumption of movement as long as the safe state is not canceled, into which the device automatically changes when an error is detected.

The fault can be one of the sensors, for example 17th , the drive 15th or the control device 19th affect. The detection of an error can for example by the control device 19th or through in the sensors 17th as well as in the drive 15th self-running function checks take place, for example at regular time intervals.

Because the drive 15th with the wing 13 Connected via a self-locking gear, the wing can be in a safe condition 13 cannot be moved manually. To remove the wing despite the fact that the device is in a safe condition 13 by means of the drive 15th to be able to move is, according to the invention, an emergency operating device 21st provided in the embodiment of 1 into one of the two sensors 17th is integrated. On possible configurations of the emergency operating device 21st is discussed in more detail below.

The emergency control device 21st works according to the dead man principle, so it requires a permanent action of an actuator, in particular a button, around the drive 15th to activate and to hold in the activated state and thus the wing 13 to start moving again and to maintain the respective movement as long as it is necessary to move the wing 13 for example to move into the closed position.

As 2 shows, it may be with the sensor 17th For example, a light button can be used in 2 its appearance 33 is shown. The emergency control device 21st is in this embodiment in the sensor 17th integrated, ie the sensor 17th and the emergency operating device 21st have a common housing 25th .

As 2 also shows, is in this embodiment also the control device 19th into the sensor 17th integrated. In other exemplary embodiments, the control device 19th be arranged elsewhere (cf. 1 ). It can - as already in connection with 1 mentioned - the control device is also a central building management system.

The emergency control device 21st includes two actuators 23a , 23b in the form of buttons on the underside of the sensor 17th arranged and so easily accessible to a user. The in 2 shown left button 23a must be pressed by a user to cause that through the controller 19th the drive 15th in the opening direction is activated to the sash 13 to move in the opening direction. Accordingly, the in 2 right button 23b pressed to the wing 13 to move in the closing direction.

According to the dead man's operation already mentioned, the user must press the respective button 23a or. 23b hold down to drive 15th activated and thus the wing 13 keep moving. If the user leaves the button 23a or. 23b go, the drive stops 15th and remains the wing 13 stand.

In this way, despite the presence of a safe state, a user on site can, for example, see a sash that has remained in the open state due to an error 13 automatically using the drive 15th close without having to call service personnel.

3 shows an alternative embodiment in which the emergency operating device 21st not in the housing 27 of the sensor 17th is integrated. Instead, there is the emergency operating device 21st as a separate unit with its own housing 29 intended. On an outside of the housing 29 are those already in connection with above 2 mentioned button 23a and 23b to open or close the sash 13 Arranged accessible to a user.

One advantage of this embodiment is that the emergency operating device 21st regardless of where the sensors are installed 17th can be placed in the area of the relevant component. This concept also allows existing automatic door or window closers and openers to be retrofitted. Despite this remote arrangement of the emergency operating device 21st is this to the sensor 17th connected and with the control device integrated in these 19th connected.
