Description

The present invention relates to the field of home automation, and more particularly to a connected device for actuating a system for closing a window or a door.

In the field of home automation, the management and monitoring of openings, in particular doors and windows, is a relatively important issue.

In fact, the control of the opening elements not only constitutes a means of home security, for example in the context of connected locks, but also constitutes a means of home automation management making it possible, in particular, to detect windows or doors that have been left open involuntarily, causing between another significant energy loss.

It is well known that window and door systems can include oscillating, sliding, tilt-and-turn assemblies or any other structure known to those skilled in the art. In addition, depending on the different implementations, the handle of such a system can either return to a rest position, for example for a conventional oscillating door, via return means, for example a spring, or maintain the position in which it is positioned, for example in the case of a tilt-and-turn window. The object of the invention is to adapt to all window and door systems known from the prior art as well as to any type of handle.

We know in particular the document DE10 2006 017654 A1 which discloses a radio adapter with magnetic contacts and magnetic control for a window or door handle capable of detecting the position of the handle.

Window systems such as those described in the patent are known in particular. EP 3,097,246 However, such a solution requiring complete adaptation of the window is relatively expensive, complex to install and cannot be adapted to existing window or door installations, for example older and / or not having a home automation function.

Also, there is a need for a simpler door or window monitoring system that can be adapted to installed equipment without a home automation function.

A device for actuating a closing system, such as a bolt, for a window or for a door, is proposed, comprising an opening and a fixed frame, said device being intended to be installed on said opening of said window. or door, said device comprising a main body and an actuating handle, said actuating handle being shaped to pass from a closed position, in which it maintains the opening leaf closed against the frame, to an open position in which the opening is free with respect to said frame, the main body having at least one fixing part intended to be secured to the opening and a removable lining part intended to be fixed at least in part against the fixing part; said handle being rotatably mounted on said fixing part.

Said device comprises a position sensor and a control member; said control member comprising at least one radiofrequency communication means capable of communicating with a remote terminal, so as to transmit to said remote terminal said position of the handle acquired by said position sensor, and to receive an acknowledgment of receipt from said remote terminal; said position sensor of said handle being installed in said fixing part, and said control member being secured to said trim part.

Thus, it is possible to obtain a device for actuating a system for closing a door or a relatively simple window and making it possible to detect and transmit to a remote terminal a change of position so that a user can know remotely if the door or window is open or closed. Such a device is in particular easily adaptable to doors or windows already installed in a home without a pre-existing home automation function.

Advantageously and in a nonlimiting manner, said lining part comprises a hollow portion, said control member being integral with said lining part in said hollow portion, so that when said lining part is installed on the fixing part, the control member is enclosed between the fixing part and the lining part.

Thus, it is possible to obtain an actuating device allowing simple access to the control member.

Advantageously and in a nonlimiting manner, the fixing part comprises a connection member able to be brought into contact with a complementary connection member installed on said lining part when said lining part is mounted on the fixing part. Thus, it is possible to simply allow communication between the position sensor and the control member in a relatively simple and reliable manner.

Advantageously and in a nonlimiting manner, said control member comprises a microcontroller capable of receiving information originating from the position sensor of the handle and of transmitting, via the radiofrequency communications means, the position of the handle to the remote terminal. Thus, an inexpensive and reliable control member can be obtained.

Advantageously and in a nonlimiting manner, the control member also comprises a microcontroller wake-up circuit, said wake-up circuit being configured to activate said microcontroller when the position sensor detects a modification of the position of said handle. Thus, the energy consumption of the device can be optimized by waking up the microcontroller only when the handle is actuated.

Advantageously and in a nonlimiting manner, the control member also comprises an active holding circuit capable of keeping the microcontroller active, after it has been activated by the wake-up circuit, so that it remains active during a phase of switching on of the microcontroller and during a phase of transmission of information to the remote terminal. Thus, it is possible to ensure that the microcontroller remains awake long enough to communicate with the remote terminal, before returning to its sleep state.

Advantageously and in a nonlimiting manner, the lining part is clipped onto the fixing part. Thus, the control member and the electric accumulator can be easily accessible by the user without tools.

Advantageously and in a nonlimiting manner, the device comprises an electric accumulator mounted on said lining part. Thus, it is possible to simplify the change of the accumulator by the user by simplifying its access.

The invention also relates to an assembly for controlling a door or a window comprising a device as described above and a remote terminal comprising radiofrequency reception means for receiving said information on the position of the handle transmitted by said control member. .

With reference to figures 1, 2a , 2b and 3 , the invention relates to a device 1 for actuating a closing system, not shown, of a window or of a door.

In the context of the present description of the invention, reference will be made to an example of implementation on a door. However, the invention can be applied to a window in a similar manner, without the need to adapt the invention.

A door includes a frame and an opening. In order to ensure closure, a door comprises a closure system, for example a bolt, mounted in the opening, which engages in a keeper formed in the frame.

The bolt is actuated by an actuator, called in common parlance door handle, causing the bolt to move back and forth in the keeper, so as to allow the opening or closing of the door. In the remainder of the description, we will talk about the actuating device 1 in order to avoid any confusion with the term handle, which is only part of the device.

Indeed, an actuating device 1 comprises a main body 10 and an actuating handle 11, also called handle 11, for example a crutch handle 11. However, the invention is not limited to a particular type of known handle. .

The main body 10 of the actuator 1 comprises a fixing part 101 and a packing part 102.

According to the invention, the handle 11 is rotatably mounted to the fixing part 101 of the main body 10, and is adapted to move from a closed position, in which the door leaf is kept closed, to a position opening, in which the sash is free to move away from the frame by rotation.

An angular sensor, not shown, is installed in said fixing part 101, so as to sense the angular position of the handle 11.

The angular position of the handle 11 in its closed and / or open position is irrelevant on the implementation of the invention. The invention is nevertheless based on the detection of a variation in angular position between the closed position and the open position of the handle 11. However, it is common practice for an angle of rotation of substantially 90 ° to be defines between the open position and the closed position of the handle, which allows detection of this relatively easy position by a sensor. Any other angle value that can be chosen by a person skilled in the art according to the need for definition of the door, and as long as this angle of rotation is greater than the detection sensitivity of the sensor.

The fixing part 101 is intended to be fixed to the opening, in the vicinity of the bolt, so that the handle 11 can cooperate with the bolt.

The fixing part 101 is in this embodiment a thermoformed plastic part comprising two fixing holes 103, 104, intended to allow the insertion of fixing screws to the opening. The main body 10, whether its fixing part 101 and its lining part are not limited to a particular type of material.

The lining part 102 is a plastic, thermoformed part, intended to come to rest in part on the fixing part 101, so as to cover the two fixing holes 103, 104, in order to hide the screws from the user.

The trim part 102 is in this embodiment mounted on the fixing part 101, by a slide link 105, 106 and by a clip tab projecting from a free end of the slide link 106 of the trim part 102 , engaging in a clip hole 108 in the fixing part 10.

Thus the trim part 102 is removable relative to the fixing part 101.

The trim part 102 comprises a hollow portion 109 extending from one end of the slide link opposite the end of the slide link 105 on which the clip tongue 107 is mounted.

A control member 30 is installed in the hollow portion 109 of the trim part 102.

This control member 30, here an integrated circuit 30 comprising a microcontroller, is supplied electrically by an electric accumulator 31, here a so-called button cell 31, mounted on the control member 30.

The invention is not, however, limited to an electric power supply by an electric accumulator 31. For example, provision can be made to power the device by a piezoelectric system, generating, for example, an electric current when handling the handle. . Such a piezoelectric system can also be coupled to an electric accumulator.

According to a particular embodiment of the invention, the device 1 can comprise on an outer part of the fixing part 101 or of the part of trim 102 a photovoltaic member 51 capable of capturing external light and recharging the electric accumulator 31.

The control unit 30 comprises a radiofrequency communication means, not shown, suitable for communicating with a remote terminal 20, for example a remote computer, a server, a security center, a multimedia box, a mobile phone, a tablet or any other means of digital communication.

The radiofrequency communication means is for example a communication device suitable for communicating via a Wi-Fi protocol, HiperLan, any low-speed communication protocol for connected objects, for example of the LoRaWAN or SigFox type, a Buetooth protocol, or any other protocols. home automation communication systems known from the prior art.

Although the invention relates to a radiofrequency communication means, those skilled in the art could adapt the invention to another type of communication, for example a wired network communication, for example of the CPL type, for Power Line Carrier, or Ethernet.

In order to allow simple transmission of the angular sensor installed in the fixing part 101 with the control member 30, the angular sensor is connected to a connection member 32, here a group of four communication pins 32. This connection member 32 is intended to cooperate with a complementary connection member 33 integral with the lining part 102, so that when the lining part 102 is mounted on the fixing part 101, the connection member 32 and the connection member complementary 33 are in electrical contact with each other, allowing the transmission of information from the angular sensor to the control member 30.

Further, the angular sensor in this embodiment does not include any dedicated power supply. Also, the connection members 32, 33 allow the angular sensor to be supplied electrically via the electric accumulator 31.

The connection members 32, 33 can for example be designed according to known standards such as USB connections, and preferably any connection means with flat contactors, so as to reduce the bulk of the connection members 32, 33.

Thus, when the handle 11 is actuated, the angular sensor installed in the fixing part 101 transmits the angular position information of the handle 11 to the control member 30, via the connection members 32, 33, so as to so that the control unit 30 can transmit this modification of position to the remote terminal 20, via the on-board radiofrequency means.

This thus makes it possible to obtain a compact actuating device 1, simple to adapt and to maintain. In particular, the electric accumulator is relatively easy to access for the user.

With reference to figures 5 and 6 , the control unit 30 comprises an electronic power supply structure 50, allowing a strong reduction in power consumption by a wake-up circuit mechanism and keeping awake for the duration of the sending of information via the means of communication radio frequency.

This electronic structure 50 which will be referred to under the term of activation structure 50 comprises the electric accumulator 31 and a relay 52, here a static relay 52, but which can alternatively be an electromechanical relay.

The electronic structure 50 comprises a start switch 54 actuated when the handle reaches a position of approximately 10 ° of rotation with respect to its closed position, or alternatively open.

The threshold angle value of 10 ° is given here as an indication, but can be replaced by any relevant angle value, in particular between 1 and 90 °. However in a conventional handle operation, passing from its closed position to its open position on a rotation of substantially 90 °, it is considered that a deviation in rotation of 10 ° from its closed position causes the opening of the door, and conversely, the passage of a rotation of the handle towards an angle of less than 10 ° from its closed position constitutes a closing of the door.

Thus, the position sensor has in this embodiment, a threshold operation, when the handle is pivoted so as to cross the threshold angle of 10 ° with respect to a rest position, here the closed position of the handle. , a threshold detection signal is transmitted to the control unit 30.

This operation by threshold of the position sensor allows correct operation of the invention regardless of the type of handle: return or static. Indeed, a handle can have a return actuation in which it returns to a rest position automatically after having been actuated, for example by the effect of return means such as a spring, while another mode of so-called static operation, maintains the handle in its position following actuation.

The sensor can then provide the control member 30 with either an angular value for the position of the handle, or in a less expensive embodiment of the sensor, an indication of the position of the handle with respect to this angle of 10 °, also called threshold angle: a position of angle greater than this threshold, or an angle position less than this threshold, which allows, knowing the position of the angle to determine if the handle is oriented towards the open position or closed.

When the start switch 54 is open, with reference to the figure 5 , the relay 52 is maintained in a switching state 56 producing no power to the microcontroller 55.

When the handle reaches the 10 ° position, a switching signal is transmitted by the position sensor, and causes a shunt 60, also called instantaneous shunt 60, with reference to the figure 6 , putting the relay 52 in a switching state 56 'producing the power supply for the microcontroller 55. Thus, the microcontroller 55 is switched on. Thus the assembly comprising the position sensor of the handle 11, the start switch 54 and relay 56 form a microcontroller wake-up circuit.

The capacitor C2, with reference to the figure 6 maintains power to relay 52 during the boot time of the microcontroller.

The start of the microcontroller is then enabled by maintaining the power supply for a period of between 1.5 seconds and 2 seconds, for a C2 capacitor of 0.01 Farad with a battery accumulator at medium voltage of 3.7V and a relay 56 comprising a 150 Ohm coil, hooking at 3V and disconnecting at 1.3V.

When the microcontroller is in operation, it then maintains the transistor T2 in the closed state. Thus, the mass is ensured on the relay 52. In this way the microcontroller itself maintains its power supply and this as long as it has not completed the task of transmitting the angular position of the handle.

Once the microcontroller has finished transmitting the position information from the handle to the remote terminal 20, it releases the power which returns to its initial sleep state according to the figure 5 .

Thus, the invention also relates to an assembly for controlling a door or a window comprising a device as described above and a remote terminal, for example a wireless reception station, comprising radiofrequency reception means for receiving said position information of the handle sent by said control member.

In order to communicate, the wireless receiving station 20 and the device 1 must communicate on a common network.

To this end, the actuating device 1 comprises on the control member an actuator, for example a push button, able to command the microcontroller to switch to an operating mode called configuration mode 421.

As the actuation device 1 comprises a circuit for waking up the microcontroller explained above, it is necessary to actuate the handle 11 in order to pass the threshold of 10 ° of rotation, this having the effect of waking the microcontroller, then of press push-button 42.

The microcontroller is then kept powered until the end of the configuration. In the embodiment described below, the actuation device 1 is adapted to operate on a home network of the Wi-Fi type. However, those skilled in the art will understand from the description how to adapt this solution to other types of communication networks.

In such a configuration mode, the control unit 30 switches to server mode, and generates a configuration Wi-Fi network 422 to which the remote terminal can connect directly.

The control unit 30 has a predetermined IP address, for example printed in a user manual or in the hollow part of the lining part 102 of the actuator 1.

When the remote terminal 20 connects to the IP address, via a web browser, data exchanges 423, for example HTML data, Javascript and Json, make it possible to communicate to the control unit 30 the name of the operating Wi-Fi network to which to connect and the associated password.

In addition, in order to allow communication and the sending of measurement data with the remote terminal 20, a step of configuring the modalities of exchanges with the remote terminal 20 is implemented.

To this end, several protocols can be used to allow communication between the actuator device
1 and the remote terminal 20.

According to a first embodiment, a webserver, in French web server, is implemented on the remote terminal 20, creating a communication interface according to the HTTP protocol, conventionally on the communication port 80.

This web server is accessible via the IP address of the remote terminal 20 on the communication network. In other words, by communicating to the control unit 30 the IP address of the remote terminal, the latter will be adapted to transmit the data to the remote terminal according to a predefined HTTP communication protocol, preferably by transmission of data in a structured format, by JSON or XML example. However, the data frame can simply be integrated into a query string for the URL address, or else encoded in an HTTP request, of the GET or POST type.

In addition, the control unit 30 can be configured to communicate with other remote terminals 20 or according to other communication protocols, for example the control unit 30 can be configured so that it communicates according to protocols suitable for transmission on applications such as Telegram, IFTTT, Android, SMS, to communicate with mail servers, home automation units according to predefined protocols, or even according to the MQTT protocol for Message Queuing Telemetry Transport. Each of these protocols comprises at least one connection address in the form of an IP address or a URL address, generally a connection key, known by the English-speaking name of API key, and / or connection identifiers.

Once this configuration has been carried out, the user, via the web browser, sends an end of configuration signal 424.

The control unit 30 then proceeds to record 425 of this configuration in a storage memory of the microcontroller, for example a flash memory, for example an integrated EEPROM, and the control unit 30 switches to so-called normal operating mode. .

In normal operating mode, the control unit 30 when it is awakened by an actuation 40 of the handle, as described above by a rotation of 10 °, implements a first step 41 of reading the configuration in the storage memory, then connects to the operating Wi-Fi network saved during the configuration step.

Then the control unit 30 establishes 43 a communication with the remote terminal 20 according to the communication protocol defined during the configuration.

The control unit 30 then acquires 44 data from the position sensor of the handle 11.

The control unit 30 then implements a step 45 of creating a data frame comprising the handle information, including its open or closed position, and optionally, the type of handle and an identifier entered by the handle. user during configuration to identify the handle among a plurality of handles.

Then the control unit 30 proceeds to the transmission 46 of the data frame, and waits for 47 a response from the remote terminal 20.

The control unit 30 is adapted to repeat the sending of the data frame 46 a plurality of times, for example 3 times, and if no response from the remote acknowledgment terminal, acknowledge in English, is received.

Thus, it is possible to provide a control assembly for a device for actuating a relatively simple, inexpensive, easily configurable, and adaptable to different communication protocols, closing system for a door or window.

According to a particular embodiment of the invention, the actuating device may further comprise an impact detection member, such as an impact sensor.

In this embodiment, the shock sensor is made of a mercury cell, in particular a “tilt switch” type cell, connected to the wake-up circuit as described above. A mercury cell present the advantage of being a passive component, requiring no external power supply, unlike an accelerometer. However, the invention could implement an accelerometer in particular if an external power supply is available.

When a shock on the handle occurs, the shock sensor wakes up, via the wake-up circuit, the microcontroller of the actuating device.After this wakeup, the control unit 30 checks the position of the handle 11.

If the handle 11 is detected as being in a position identical to that recorded before the alarm clock, then it is deduced that the wake-up circuit has been activated by the shock sensor, and the control unit 30 issues a shock notification by the alarm clock. communication protocol previously configured.
