Description

The present invention relates to a method of operating a motorized drive device of a window for a building, so as to move an opening relative to a fixed frame and to lock the opening relative to the fixed frame in at least one predetermined locked position.

The present invention also relates to a window for a building incorporating such a motorized drive device, as well as a home automation installation comprising such a window.

In general, the present invention relates to the field of windows comprising a motorized drive device setting an opening leaf in motion relative to a fixed frame, between at least a first position and at least a second position.

A motorized drive device for such a window comprises an electromechanical actuator.

We already know the document EP 1 507 059 A2 which describes a sliding window for a building comprising a fixed frame, an opening, a motorized drive device for sliding the opening relative to the fixed frame and a device for locking the opening relative to the fixed frame in a closed locked position. The motorized drive device comprises an electromechanical actuator, an electronic control unit, a flexible element and a drive arm. The electromechanical actuator includes an electric motor. The flexible element is configured to drive the opening leaf relative to the fixed frame, when the electromechanical actuator is electrically activated.

The locking device is arranged inside a side post of a frame of the opening. The lateral upright of the opening frame is configured to cooperate with the fixed frame in a closed position of the opening relative to the fixed frame. The drive arm is integral with a shaft of the locking device and mounted to be movable in rotation about an axis of rotation of the shaft of the locking device.

However, this document is silent concerning a determination of a current position of the opening relative to the fixed frame, in particular in the case where a manual displacement of the opening relative to the fixed frame is implemented by a user.

Therefore, no information is provided in this document concerning arrangements to avoid crushing or pinching of a user when reaching an end position or a predetermined position, so as to ensure user safety.

We also know the document WO 2012/139860 A1 relating to the operation of a door and in which a sampling frequency depends either on the position of a rotor or on its speed of rotation, without taking into account whether the door is locked or not.

The object of the present invention is to resolve the aforementioned drawbacks and to propose a method for controlling in operation a motorized drive device for a window for a building, a window for a building comprising such a motorized drive device, as well as a home automation installation comprising such a window, making it possible to determine a current position of the opening relative to the fixed frame during a movement of the opening relative to the fixed frame, both motorized and manually, all by guaranteeing the safety of a user, in particular when reaching an end-of-travel position or a predetermined position, and by limiting the consumption of electrical energy by the motorized drive device.

Thus, when moving the first leaf 3a relative to the fixed frame 4 in a first direction of sliding, in particular when moving from the closed position to an open position of the first leaf 3a relative to the fixed frame 4, the first strand 9a of the flexible element 9 wraps around the first part of the winding pulley 19, while the second strand 9b of the flexible element 9 unwinds around the second part of the winding pulley 19.

In addition, when moving the first leaf 3a relative to the fixed frame 4 in a second sliding direction, in particular when moving from an open position to the closed position of the first leaf 3a relative to the fixed frame 4, the first leg 9a of the flexible element 9 unwinds around the first part of the winding pulley 19, while the second strand 9b of the flexible element 9 winds around the second part of the winding pulley 19.

The second sliding direction of the first opening 3a relative to the fixed frame 4 is opposite to the first sliding direction.

In this way, the direction of drive in rotation of the first strand 9a of the flexible element 9 around the first part of the winding pulley 19 is opposite to the direction of drive in rotation of the second strand 9b of the element. flexible 9 around the second part of the winding pulley 19.

Advantageously, the direction of sliding of the first leaf 3a relative to the fixed frame 4 is determined as a function of the direction of rotation of the output shaft 8 of the electromechanical actuator 6. In addition, the direction of rotation of the drive. Winding pulley 19 is determined by the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

Thus, the direction of drive in rotation of the first strand 9a and of the second strand 9b of the flexible element 9 around the first and second parts of the winding pulley 19 is a function of the direction of rotation of the output shaft 8. of the electromechanical actuator 6.

Advantageously, the retractable pin 34 extends in a direction perpendicular to the cremone bolt.

As a variant, not shown, the fitting system 20 can be devoid of the anti-mishandling system 27.

Preferably, the drive arm 18 and the first locking device 21 are arranged in the upper part of the first lateral upright 15c of the frame 15 of the first opening 3a, in the assembled configuration of the window 2 with respect to the building.

Thus, the drive arm 18 is configured to hook onto the flexible element 9 arranged above the fixed frame 4, in particular the upper cross member 4a of the fixed frame 4.

In addition, the drive arm 18 and the first locking device 21 are arranged closest to the flexible element 9, since the flexible element 9 extends along the upper cross member 4a of the fixed frame 4.

Preferably, the drive arm 18 is fixed, and therefore immobile, relative to the frame 15 of the first opening 3a.

In this way, the connection between the drive arm 18 and the frame 15 of the first leaf 3a is simplified and makes it possible to minimize the costs of obtaining the window 2.

We will now describe, with reference to figure 5 , an embodiment of a method of operating the motorized drive device 5 of the window 2 illustrated in figures 1 to 4 .

The method for controlling the motorized drive device 5 in operation comprises a monitoring step E20, by means of the electronic control unit 10, of the signal S coming from the counting device 24 at the predetermined frequency F as a function of the position of the first leaf 3a relative to the fixed frame 4. Apart from the locked position of the first leaf 3a relative to the fixed frame 4, the predetermined frequency F has at least a first value F1. In addition, in the locked, closed or ajar position of the first opening 3a with respect to the fixed frame 4, the predetermined frequency F has a zero value or a second value F2, the second value F2 of the predetermined frequency F being less than the predetermined frequency F. first value F1 of the predetermined frequency F.

Thus, the motorized drive device 5 makes it possible to determine a current position of the first sash 3a relative to the fixed frame 4, by means of the counting device 24 and of the electronic control unit 10, during a movement of the first. opening 3a with respect to the fixed frame 4, implemented either by means of the motorized drive device 5 or manually by the user, that is to say without electrically activating the electromechanical actuator 6, while ensuring safety of the user, in particular when reaching an end-of-travel position, which may be, in particular, the closed position of the first leaf 3a with respect to the fixed frame 4 or the fully open position of the first leaf 3a with respect to to the fixed frame 4, or to a predetermined position, which may be, in particular, the half-open locked position of the first leaf 3a relative to the fixed frame 4, and by limiting a electrical energy consumption of the motorized drive device 5.

In this way, the counting device 24 and the electronic control unit 10 are configured to determine a position of the first sash 3a with respect to the fixed frame 4 at any time, by means of the sensor (s) 32 of the counting device. 24, so as to guarantee the safety of the user.

Moreover, as long as the first leaf 3a is outside the locked position relative to the fixed frame 4, the monitoring of the signal S coming from the counting device 24 by the electronic control unit 10 is implemented according to the first value F1 of the predetermined frequency F.

In addition, when the first leaf 3a is in the locked position relative to the fixed frame 4, the monitoring of the signal S coming from the counting device 24 by the electronic control unit 10 is either deactivated, that is to say that the predetermined frequency F for monitoring the signal S coming from the counting device 24 by the electronic control unit 10 is zero, or implemented according to the second value F2 of the predetermined frequency F.

In this way, when the first sash 3a is in the locked position with respect to the fixed frame 4, either the interruption of monitoring the signal S coming from the counting device 24 or the decrease in the predetermined frequency F of monitoring the signal S coming from of the counting device 24 makes it possible to reduce the electrical energy consumption of the motorized drive device 5 and, more particularly, of the electronic control unit 10, while guaranteeing the memorization of the current position of the first leaf 3a with respect to the fixed frame 4, by means of the electronic control unit 10, since manual movement of the first sash 3a relative to the fixed frame 4 in the locked, closed or ajar position is prevented by means of the first or the second locking device 21, 22.

Advantageously, the first value F1 of the predetermined frequency F is dependent on a frequency of the microcontroller of the electronic control unit 10, in particular of a clock of the microcontroller, and, more particularly, corresponds to a frequency of the microcontroller.

As a variant, the first value F1 of the predetermined frequency F is independent of the frequency of the microcontroller.

By way of non-limiting example, the first value F1 of the predetermined frequency F may be of the order of 100 kilohertz.

By way of non-limiting example, the second value F2 of the frequency F predetermined may be of the order of one Hertz.

Advantageously, when the first opening 3a is outside the locked position relative to the fixed frame 4, the electronic control unit 10 is informed of a change of state of the counting device 24 and, more particularly, of the one of the sensors 32 of the counting device 24, as a function of the first value F1 of the predetermined frequency F. In addition, the counting device 24 and, more particularly, the sensors 32 are continuously supplied with electrical energy.

Advantageously, when the first opening 3a is in the locked position relative to the fixed frame 4, the electronic control unit 10 determines a change of state of the counting device 24 and, more particularly, of one of the sensors 32 of the counting device 24, as a function of the second value F2 of the predetermined frequency F. In addition, the counting device 24 and, more particularly, the sensors 32 are supplied with electrical energy periodically, in particular according to the second value F2 of the predetermined frequency F.

Advantageously, prior to the monitoring step E20, the method comprises a step of determining the position E10 of the first opening 3a relative to the fixed frame 4.

Thus, the monitoring step E20 is implemented as a function of the determined position of the first leaf 3a relative to the fixed frame 4.

In this way, in the case where the first opening 3a is positioned outside the locked position relative to the fixed frame 4, the monitoring step E20 is implemented according to the first value F1 of the predetermined frequency F. In addition, in the case where the first leaf 3a is positioned in the locked position relative to the fixed frame 4, the monitoring step E20 is either temporarily inhibited, in particular by temporarily interrupting the monitoring of the signal S coming from the counting device. 24, or implemented according to the second value F2 of the predetermined frequency F.

Here, step E10 of determining the position of the first opening 3a relative to the fixed frame 4 is implemented by means of the electronic control unit 10 and the counting device 24.

Advantageously, the method comprises a step of determining a manual displacement E30 of the first leaf 3a relative to the fixed frame 4.

Preferably, the step of determining a manual displacement E30 is implemented, on the one hand, when the first leaf 3a is positioned outside the locked position relative to the fixed frame 4 and, on the other hand, when the first sash 3a is positioned in the locked position relative to the fixed frame 4.

Here, the step of determining a manual displacement E30 of the first leaf 3a relative to the fixed frame 4 is implemented by means of the electronic control unit 10 and the counting device 24.

Advantageously, when a manual movement of the first leaf 3a relative to the fixed frame 4 is determined, during the step of determining a manual movement E30, the method comprises a step of determining the direction of manual movement E40 of the first leaf. 3a in relation to the fixed frame 4.

Here, the step of determining the direction of manual movement E40 of the first leaf 3a relative to the fixed frame 4 is implemented by means of the electronic control unit 10 and the counting device 24.

Advantageously, following a manual movement of the first leaf 3a relative to the fixed fixed frame 4, during the step of determining a manual movement E30, from the locked, closed or ajar position, the method comprises a first step E50 for resetting the position of the first leaf 3a with respect to the fixed frame 4 by the counting device 24 and the electronic control unit 10.

Thus, in the case where a manual displacement of the first leaf 3a relative to the fixed frame 4 is determined, from the locked position, the method implements the first step of resetting E50 of the position of the first leaf 3a relative to the fixed frame 4.

In the case where the first leaf 3a is positioned in the locked closed position relative to the fixed frame 4, the first resetting step E50 corresponds to a detection of the closed position of the first leaf 3a relative to the fixed frame 4 and, optionally, the fully open position of the first sash 3a in relation to the fixed frame 4.

In the case where the first leaf 3a is positioned in the half-open locked position relative to the fixed frame 4, the first resetting step E50 corresponds to detection of the locked half-open position.

Advantageously, the first resetting step E50 is implemented by means of the electronic control unit 10 and the counting device 24.

Advantageously, the first resetting step E50 is implemented by controlling the electric motor 7 of the electromechanical actuator 6 according to the second speed setpoint V2.

Thus, during the first resetting step E50, the electric motor 7 of the electromechanical actuator 6 is controlled at a reduced speed setpoint relative to a nominal speed setpoint of the electric motor 7, so as to protect the window 2 and, more particularly, the motorized drive device 5.

Advantageously, the first resetting step E50 can be implemented following the step of determining a manual displacement E30 or following the step of determining the direction of manual displacement E40.

Advantageously, following the first resetting step E50, the method again implements the step of determining a manual displacement E30 of the first leaf 3a relative to the fixed frame 4, which is shown in figure 5 .

Advantageously, the first drive step E60 of the first opening 3a relative to the fixed frame 4 is implemented in the opposite direction of movement with respect to the direction of movement of the first opening 3a relative to the determined fixed frame 4, during the 'step for determining the direction of manual movement E40.

Thus, the implementation of the first drive step E60 of the first sash 3a relative to the fixed frame 4 in the opposite direction of movement of the first sash 3a relative to the determined fixed frame 4, during the step of determining the direction of manual movement E40, makes it possible to go against the manual movement of the first leaf 3a with respect to the fixed frame 4.

In this way, such an implementation of the first drive step E60 of the first opening 3a relative to the fixed frame 4 makes it possible to avoid an attempted break-in, in particular in the case where the electromechanical actuator 6 is of type reversible.

In this case, the first drive step E60 is implemented following the step of determining the direction of manual movement E40.

In an exemplary embodiment, following a manual movement of the first leaf 3a relative to the fixed fixed frame 4, during the step of determining a manual movement E30, from the locked, closed or ajar position, the method can implement the first drive step E60 of the first opening 3a relative to the fixed frame 4 in combination with the monitoring step E20 according to the first value F1 of the predetermined frequency F.

Advantageously, during the first drive step E60, the method again implements the step of determining the position E10 of the first leaf 3a with respect to the fixed frame 4.

Thus, the method makes it possible to determine the current position of the first leaf 3a relative to the fixed frame 4, during the movement of the first leaf 3a relative to the fixed frame 4 by means of the motorized drive device 5.

Advantageously, the first drive step E60 is implemented by controlling the electric motor 7 of the electromechanical actuator 6 according to the first speed setpoint V1.

Thus, during the first drive step E60, the electric motor 7 of the electromechanical actuator 6 is controlled at a nominal speed setpoint of the electric motor 7, so as to reach the locked position, in particular closed, as quickly as possible. possible.

Here, the triggering step E70 of an alarm signal A is implemented by means of the electronic control unit 10.

In an exemplary embodiment, following a manual movement of the first leaf 3a relative to the fixed fixed frame 4, during the step of determining a manual movement E30, from the locked, closed or ajar position, the method can implement the triggering step E70 of an alarm signal A in combination with at least the first resetting step E50 or the first training step E60.

Advantageously, the alarm signal A is emitted by means of a device alarm, not shown, receiving a message from the means of the communication module 23 of the electronic control unit 10.

As a variant, the alarm signal A is emitted by means of the motorized drive device 5 and, more particularly, of the electromechanical actuator 6 configured to emit the alarm signal A, which may be, in particular, audible or vibratory.

Advantageously, following a manual movement of the first opening 3a relative to the fixed fixed frame 4, during the step of determining a manual movement E30, from a position different from the locked position, the monitoring step E20 is implemented according to a third value F3 of the predetermined frequency F. The third value F3 of the predetermined frequency F is greater than the first value F1 of the predetermined frequency F.

Thus, the monitoring step E20 is also implemented as a function of the determined type of movement of the first leaf 3a relative to the fixed frame 4, either manual or motorized.

In this way, when a manual movement of the first leaf 3a relative to the fixed frame 4 is determined, during the step of determining a manual movement E30, from a position different from the locked position, the increasing the predetermined frequency F of monitoring the signal S coming from the counting device 24 makes it possible to guarantee a more precise determination of the position of the first leaf 3a with respect to the fixed frame 4.

In such a case, the increase in the predetermined frequency F of monitoring the signal S coming from the counting device 24 is particularly advantageous since the speed of a manual movement of the first leaf 3a relative to the fixed frame 4 can be greater than the speed of a movement of the first leaf 3a relative to the fixed frame 4 implemented by the motorized drive device 5.

Advantageously, during the monitoring step E20 implemented according to the third value F3 of the predetermined frequency F, the method again implements the step of determining the position E10 of the first leaf 3a with respect to the fixed frame 4 .

Thus, the method makes it possible to determine whether the first leaf 3a is positioned in the locked, closed or ajar position, with respect to the fixed frame 4, following the determined manual movement, during the step of determining a manual movement E30.

As a variant, following a manual movement of the first leaf 3a relative to the fixed frame 4, during the step of determining a manual displacement E30, from a position different from the locked position, the method comprises a second step E80 for driving the first leaf 3a relative to the frame 4 by means of the motorized drive device 5, in other words by the electrical activation of the electromechanical actuator 6.

In an exemplary embodiment, following a manual movement of the first leaf 3a relative to the fixed fixed frame 4, during the step of determining a manual movement E30, from a position other than the locked position, the method can implement the second drive step E80 of the first opening 3a relative to the fixed frame 4 in combination with the monitoring step E20 according to the third value F3 of the predetermined frequency F.

Advantageously, the second drive step E80 of the first opening 3a relative to the fixed frame 4 is implemented in the same direction of movement as the direction of movement of the first leaf 3a relative to the determined fixed frame 4, during the step for determining the direction of manual movement E40.

Thus, the implementation of the second drive step E80 of the first sash 3a relative to the fixed frame 4 in the same direction of movement of the first sash 3a relative to the determined fixed frame 4, during the step of determining the direction of manual movement E40, makes it possible to accompany the movement of the first leaf 3a relative to the fixed frame 4 by means of the motorized drive device 5, as well as to facilitate the handling of the first leaf 3a relative to the fixed frame 4 by the 'user.

In this way, such an implementation of the second drive step E80 of the first leaf 3a relative to the fixed frame 4 makes it possible to provide an automatic starting function of the first leaf 3a relative to the fixed frame 4, by the intermediary of the motorized drive device 5, in particular in the case where all of a displacement force of the first leaf 3a relative to the fixed frame 4 is produced by the motorized drive device 5.

Furthermore, such an implementation of the second drive step E80 of the first leaf 3a relative to the fixed frame 4 makes it possible to provide a function of assisting a movement of the first leaf 3a relative to the fixed frame 4, by by means of the motorized drive device 5, in particular in the case where only part of a displacement force of the first leaf 3a relative to the fixed frame 4 is produced by the motorized drive device 5.

In this case, the second training step E80 is implemented following the step of determining the direction of manual movement E40.

Advantageously, during the second drive step E80, the method again implements the step of determining the position E10 of the first opening 3a with respect to the fixed frame 4.

Thus, the method makes it possible to determine whether or not the first sash 3a reaches the locked, closed or ajar position, relative to the fixed frame 4, during the movement of the first sash 3a relative to the fixed frame 4 by means of the drive device. motorized 5.

Advantageously, the second drive step E80 is implemented by controlling the electric motor 7 of the electromechanical actuator 6 according to the first speed setpoint V1 or according to the second speed setpoint V2, depending on the position of the first leaf 3a by relative to the fixed frame 4.

Advantageously, when the first sash 3a is in the locked, closed or ajar position, relative to the fixed frame 4 and prior to a step of executing a command order E90 to move the first sash 3a relative to the fixed frame 4 by the electronic control unit 10, the method can also comprise a step of controlling a manual displacement E100 of the first leaf 3a relative to the fixed frame 4 implemented automatically by the electronic control unit 10. L 'step of controlling a manual movement E100 of the first leaf 3a relative to the fixed frame 4 corresponds to an attempt to move the first leaf 3a relative to the fixed frame 4 from the current position, by performing a command order of the first opening 3a relative to the fixed frame 4 towards a stop.

Advantageously, in the case where the position of the first sash 3a relative to the fixed frame 4 known by the electronic control unit 10 is the locked closed position, the movement control command executed, during the control step E100 , is a closing command order to the locked closed position. In addition, the stopper corresponds to the closed locked position.

Advantageously, in the case where the position of the first sash 3a relative to the fixed frame 4 known by the electronic control unit 10 is the half-open locked position, the movement control command executed, during the control step E100 , is an opening control command to the fully open position. In addition, the stopper corresponds to the half-open locked position.

Thus, in the case where the electronic control unit 10 determines that the stop has been reached before the expiration of a first predetermined period of time P, from The instant of execution of the movement command order, the electronic control unit 10 determines that no manual movement of the first opening 3a relative to the fixed frame 4 has been carried out.

Furthermore, in the event that the electronic control unit 10 determines that the stopper has not been detected during the elapse of the first predetermined period of time P, the electronic control unit 10 determines that a manual movement of the first opening 3a relative to the fixed frame 4 has been produced.

In this way, the electronic control unit 10 deduces that the current position of the first opening 3a with respect to the fixed frame 4 is no longer known.

Advantageously, the first predetermined period of time P can be identical or different depending on the known initial position of the first leaf 3a with respect to the fixed frame 4 by the electronic control unit 10, which is either the locked closed position or the position half-open locked.

Advantageously, the method comprises a step of detecting a cut in the supply of electrical energy E110 to the motorized drive device 5.

Thus, when an electrical power supply cutout greater than the second predetermined period of time L is detected, during the detection step E110, the method implements the second step E120 of resetting the position of the first opening leaf. 3a relative to the fixed frame 4. The second resetting step E120 corresponds to a detection of the closed position of the first leaf 3a relative to the fixed frame 4 and, optionally, of the fully open position of the first. opening 3a with respect to the fixed frame 4, as well as, possibly, from the half-open locked position, in particular by means of the electronic control unit 10.
