Description

The present invention relates to an electrically triggerable door or window opener with a housing, an opening latch arranged in the housing, and at least one unit for detecting at least one presence of a bolt in a locked position of a door or window lock interacting with the door or window opener , Furthermore, the present invention relates to a door or window locking system comprising a door or window lock and a door or window opener.

Electrically releasable door and window openers are generally known and are mostly installed in the door or window frame in relation to an insert-bolt latch lock installed in the door or window wing. In principle, however, they can also be provided in a door or window sash opposite the door or window leaf provided with the mortise lock. When the door or window is closed, the lock latch of the mortise lock installed in the relevant door leaf or window engages in the resiliently pretensioned rotating body of the door or window opener referred to as the opening latch.

The publication D1 ( WO 2016/064816 A1 ) discloses an electrically or manually operated locking device which has a magnetic reed switch for monitoring the locking state. A printed circuit board and the reed switch attached to it form a component which is coated with a plastic or another synthetic material.

Known bolt switch contacts are provided for monitoring the locking of doors or windows, which have, for example, plug-in bolt latch locks, which can deliver messages about the locking state to alarm systems, building monitoring systems, panels, etc. Such separate, mechanical bolt switch contacts require a relatively large amount of space and transmit the messages to a control device by means of a movable cable. This has the disadvantage that in the event of a cable break Locked state or the bolt position of a door or window lock can no longer be communicated.

The object of the present invention is to provide a door or window opener which enables the locking of doors or windows to be monitored while at the same time minimizing the space requirement of the door or window opener and avoids a cable break.

This object is solved by the subject matter of claim 1. Further advantageous embodiments of the invention can be found in the subclaims, the following description and the drawings.

A door or window opener according to the invention comprises a housing, an opening latch arranged in the housing, and at least one unit for detecting at least one presence of a bolt in a locked position of a door or window lock interacting with the door or window opener. The invention is characterized in that the at least one unit has at least one contactless sensor and that the at least one unit is arranged in or on the housing.

A contactless sensor usually has no moving parts that can be worn out or even broken during use.

Furthermore, such contactless sensors are relatively small, which means that the space requirement of such a component is reduced compared to a mechanical sensor. This reduced space requirement even enables the sensor or a unit comprising this sensor to be accommodated in or on the housing of the door or window opener.

The contactless sensor is advantageously an inexpensive and space-saving sensor reflex light barrier or an infrared sensor or a radar sensor or an infrared sensor or a magnetic field sensor or the like.

The at least one unit is preferably arranged in the region of the opener latch. The bolt of a door or window lock interacting with the door or window opener is generally arranged above or below the lock latch. Due to the arrangement of the at least one unit in the area of the opening latch, this is also arranged in the area of the bolt and enables an even more compact construction of the door or window opener.

According to the invention, the at least one unit is arranged in the housing and a field of view of the at least one contactless sensor is directed outward from the housing. Thus, no further components are arranged between the door or window opener and the bolt, so that incorrect determinations about the presence of the bolt in a locking position can be avoided.

The contactless sensor is particularly preferably arranged on a circuit board in the housing, the circuit board preferably also being electrically connected to the opening latch or to components of the opening latch. At least some of the electrical components of the unit are thus arranged in the housing of the door or window opener. This offers protection against mechanical wear of these components. Furthermore, electrical components of a preferably electrically triggerable door or window opener can also be arranged on this circuit board, which further reduces the space required for electrical components within the housing.

The contactless sensor is advantageously connected to a microcontroller on the circuit board by means of an interface, for example a master-slave bus, preferably an I ² C interface. The arrangement of a microcontroller on the board enables short signal paths and therefore no longer delays in detecting the presence of the bolt in a locked position. The use of such an interface enables improved connectivity of the sensor to the microcontroller and enables the connection of several sensors to one bus at the same time.

The microcontroller is particularly preferably designed to process at least signals of the contactless sensor. This creates a door or window opener that can directly output signals about the presence of the bolt in a locking position.

In particular, the contactless sensor and / or the microcontroller is / are connected to a bridge rectifier on the circuit board. An AC voltage provided at the door or window opener can consequently be converted into a DC voltage of the desired strength within the door or window opener.

Further sensors can preferably be connected to the circuit board or the microcontroller. Such additional sensors can e.g. include a proximity sensor. When a person approaches when the door or window lock is not locked by means of a proximity sensor, the door or window opener can, for example, allow the opener latch to be unlocked and thus allow the person to pass through the monitored door.

The software advantageously automatically recognizes the number of connected sensors on the microcontroller or on the circuit board.

Two contactless sensors are preferably provided in the housing, a first sensor being arranged above and a second sensor below the opening latch. By providing two sensors, the door or window opener can be used in both DIN directions.

A switch is advantageously provided, by means of which one of the two contactless sensors can be selected for use, the switch preferably being arranged on the circuit board and / or in or on the housing or being provided by a function of the microcontroller. Such a switch or function enables the door or window opener to be set before or during its installation, so that the door or window opener can be used in the DIN right or DIN left state. Furthermore, by using the switch, a power supply to the sensor or unit not being used can be prevented, so that the power consumption can be reduced.

In particular, the housing is fastened to a fitting which has two cutouts for the bolt of the door or window lock interacting with the door or window opener. A fitting enables the door or window opener to be easily accommodated and connected in a door or window frame or a door or a window.

A contactless sensor is particularly preferably assigned to a recess and designed to monitor a space adjacent to the respective recess in order to detect the presence of the bolt in the locking position in this space, preferably with a field of view of the contactless sensor directed towards the respective space , The fitting thus additionally defines at least one interface of the field of view of a sensor in the direction of the door or window lock. This field of view is reduced in size, which leads to a reduction in the data flow of a contactless sensor.

In particular, a further interface is provided in or on the housing, by means of which communication between the door or window opener and a control device of a monitoring system is made possible, preferably wherein upon detection of the presence of the bolt in the locking position, a monitoring mode of the control device can be actively switched. The signals or data about the locking state obtained by means of the sensor can accordingly be forwarded to a monitoring system by means of the interface, conversely, signals or data can also be transmitted from the monitoring system to the door or window opener by means of the interface.

In a further aspect, the present invention relates to a door or window locking system which comprises a door or window lock with a bolt and a door or window opener according to the invention.

The advantages that were explained in connection with the door or window opener apply mutatis mutandis to the door or window locking system.

The invention is explained below purely by way of example with reference to the drawings. Show it:

a schematic circuit of the components of the device according to Fig. 3 ,

The 1a and 1b each show perspective views of a door opener 10 according to the invention. A housing 14 of the door opener is on a fitting 12 10 attached. An opening latch 16 is arranged in the housing 14. The opener latch 16 is designed to interact with a lock latch 20 arranged in a door lock 18 (see, for example Fig. 2a ).

For this purpose, the opener latch 16 can be pivoted between a rest position serving for locking and an unlocked position. The pivoting is e.g. caused by a spring unit, not shown. In a multi-party house (not shown) or the like, the opener latch 16 can be unlocked in a known manner by means of a house intercom (also not shown) if access is to be allowed.

The fitting 12 also has two cutouts 22. The cutouts 22 are provided for interaction with a bolt 24 of the door lock 18. The door opener 10 can be arranged in a door frame or a door leaf and fastened there by means of screws (not shown) which are guided through screw holes 26 in the fitting 12.

In the Fig. 1a the door opener 10 is shown with its housing 14 from below. In the Fig. 1b the door opener 10 is the Fig. 1a shown from above. The housing 14 has a unit 28 arranged in the area of the opener latch 16. The unit 28 is provided to detect the presence of the bolt 24 in a space 30 formed between the housing 14 and the fitting 12.

For this purpose, the unit 28 comprises two contactless sensors 32 whose respective fields of view 32 '(see Fig. 3 ) cover the respective space 30 below or above the housing 14 or the opening latch 16. A sensor reflex light barrier is preferably used as the contactless sensor 32. The Fig. 1a shows the first contactless sensor 32, which is arranged above the opening latch 16 and the Fig. 1b shows the second contactless sensor 32, which is arranged below the opening latch 16.

An interface 34 is arranged in the housing 14 in order to supply the electric door opener 10 with current and in order to be able to forward signals from or to the door opener 10 if necessary. Using this interface 34, e.g. Signals of the two contactless sensors 32 of the unit 28 and of the door opener 10 are forwarded to a control device of a monitoring system (not shown in each case).

Through the use of two sensors in a unit 28 for monitoring a locking position of the bolt 24 of the door lock 18 is in the 1a and 1b shown door opener 10 designed for both DIN directions. Thus, one and the same door opener 10 can be provided for the left and right DIN directions and no different door openers 10 are required for different DIN directions.

The Fig. 2a shows the door opener 10 of the 1a and 1b in the installed state according to DIN left, ie the inward opening door (not shown) has its hinges on the left. The door opener 10 is in the Fig. 2b shown on the right in the installed state according to DIN, ie the inward opening door (not shown) has its hinges on the right.

The Fig. 3 shows the components of the unit 28 which are integrated in the housing 14 of the door opener. At the top of the Fig. 3 the contactless sensor 32 is arranged, which monitors the space 30 with its field of view 32 ′ in order to determine whether a bolt 24 of a door lock 18 is arranged in the space 30 or not, ie to detect whether or not a door lock 18 is in its locked position , The sensor 32 is arranged in the unit 28 on a circuit board 36 and by means of an i ² C interface 38 (see Fig. 4 ) connected to a microcontroller 40.

The unit 28 is accommodated in the housing 14 in such a way that the sensor 32 is also arranged in the housing and only the field of view 32 ′ of the sensor 32 is out of the housing in the direction of the space 30 or the bolt 24 of the door lock which is in its locked position 18 directed.

The Fig. 4 shows schematically an electrical circuit of the electrical components of the unit 28 which are arranged on the circuit board 36. A bridge rectifier 42, a diode 44 and a capacitor 46 are provided in order to convert an AC voltage supplied by a power supply with a voltage of, for example, 12 V to 24 V into a DC voltage of, for example, 5 V. Both the microcontroller 40 and the contactless sensor 32 designed as a reflex light barrier are operated by means of the direct voltage. In order to ensure or regulate the power supply to the microcontroller, a regulating device 48 is also provided.

For example, a monitoring system (not shown) can be connected to the door opener 10. If it is detected that the bolt 24 is in its locking position (see Fig. 2a or 2 B ), an alarm system or the like that is coupled to the monitoring system can be activated, or vice versa.

The microcontroller 40 can also be designed to cooperate with further sensors 50 or components (not shown). Furthermore, the microcontroller 40 can be designed to forward signals, which correspond to the monitoring state of the locking position of the bolt 24, to a control device.

Because the electrical components of the unit 28 are connected directly to the sensor 32 or the circuit board 36 and are arranged in the housing 13 of the door opener 10, a cable break is avoided, among other things.

Furthermore, due to the selected arrangement of a contactless sensor for detecting a locking position, the space of a mechanical sensor is not required, so that the space required by the sensor 32 is also reduced.

Instead of one unit 28, two units 28 can also be provided in the housing, which are then each assigned to a contactless sensor 32. The two units 28 then each have their own microcontroller 40.

In order to select between one of the contactless sensors 32 when using the door opener, more precisely to use the door opener in the state DIN right or DIN left, a switch (not shown) can be provided in or on the door opener 10, or will be communicated to the microcontroller when installing the door opener 10 via the interface 34 and thus taught in the door opener. As a result, the power supply to the unused contactless sensor 32 can be prevented and a power consumption of the door opener 10 can be minimized.

The door opener 10 is preferably installed in a door frame (not shown), so that the wiring of the power supply and the signals which are forwarded to or from the door opener 10 can be transmitted by means of stationary components, for example cables, and not in movable components Door. The door opener 10 is preferably used with a non-electrical door lock 18.
