The window 2 also includes a fitting system, not shown, formed between the sleeping frame 4 and each opening 3a, 3b.

The window fitting system is well known to those skilled in the art and need not be described in more detail here. The fitting system of window 2 is not shown in FIGS. 1 and 2, so as to facilitate the reading thereof.

The fitting system of the sliding window 2 makes it possible to slide each opening 3a, 3b relative to the sleeping frame 4 in a sliding direction D, in the horizontal example, in the assembled configuration of the window 2 relative to the building, as illustrated in Figures 1 and 2.

The window 2 comprises sliding elements, not shown, allowing the movement of each opening 3a, 3b relative to the sleeping frame 4. The sliding elements are arranged inside the first and second sliding rails of the lower cross member.

In practice, the sliding elements comprise rollers arranged under the first and second opening 3a, 3b. The casters are configured to roll inside the first and second sliding rails of the bottom rail.

A sliding opening position, partial or maximum, of each opening 3a, 3b relative to the sleeping frame 4 corresponds to a building ventilation position.

The motorized drive device 5 allows the first opening 3a to be moved automatically by sliding relative to the sleeping frame 4, in particular between the maximum opening position by sliding the first opening 3a relative to the sleeping frame 4 and the closed position of the first opening 3a relative to the sleeping frame 4.

The motorized drive device 5 comprises an electromechanical actuator 6. The electromechanical actuator 6 comprises an electric motor 7. The electromechanical actuator 6 also comprises an output shaft 8, which is rotatable about an axis of rotation X.

Here, the axis of rotation X is parallel to the sliding direction D of the first opening 3a relative to the sleeping frame 4 and, in this case, of the second opening 3b relative to the sleeping frame 4.

Advantageously, the electric motor 7 of the electromechanical actuator 6 is of the variable speed type. The electric motor 7 is configured to drive the output shaft 8 in rotation according to at least a first rotation speed setpoint and a second rotation speed setpoint, so that the displacement of the first leaf 3a relative to the frame 4 is implemented either at a first speed or at a second speed, different from the first speed.

Here, the electric motor 7 is of the brushless type with electronic switching, also called “BLDC” (acronym of the Anglo-Saxon term BrushLess Direct Current) or “synchronous with permanent magnets”.

Preferably, the electromechanical actuator 6 is of the reversible type.

Here, the electromechanical actuator 6 is controlled by an electronic control unit 10 belonging to the motorized drive device 5. Such an electronic control unit 10 makes it possible to determine the position of the first leaf 3a relative to the frame 4, as well as trigger movements of the first opening 3a relative to the sleeping frame 4 by means of the electromechanical actuator 6, independently.

Preferably, the electronic control unit 10 associated with the electromechanical actuator 6 is configured to detect a movement of the first leaf 3a relative to the sleeping frame 4 implemented manually and, more particularly, by an element external to the electromechanical actuator 6 acting on the first opening 3a.

Advantageously, the electromechanical actuator 6 is devoid of a brake, in particular to allow the electromechanical actuator 6 to be reversible.

The electromechanical actuator 6 is arranged on a fixed part relative to the window 2, in particular relative to the sleeping frame 4.

The electromechanical actuator 6 can also include a reduction device, in particular with gears, not shown.

The electromechanical actuator 6 may also include a device for detecting the end of the travel and / or obstacle, not shown. This detection device can be mechanical or electronic.

Advantageously, the electric motor 7 and, optionally, the reduction device are arranged inside a casing 17 of the electromechanical actuator 6.

As illustrated in FIGS. 1 and 2, the motorized drive device 5 also comprises a flexible element 9. The flexible element 9 is driven in displacement by the electromechanical actuator 6.

The flexible element 9 is configured to drive the first opening 3a in displacement relative to the sleeping frame 4, when the electromechanical actuator 6 is electrically activated.

Here, the flexible element 9 comprises a first strand 9a and a second strand 9b.

The flexible element 9 can be of circular section. The section of the flexible element is not limiting and may be different, in particular square, rectangular or even oval.

In practice, the flexible element 9 is a cable or a cord.

It can be made of a synthetic material, such as for example nylon or polyethylene of very high molecular weight. Thus, the use of a flexible element 9 made of synthetic material makes it possible to minimize the diameter of the pulleys of the motorized drive device 5.

The material of the flexible element is not limiting and may be different. In particular, it may be a steel.

The motorized drive device 5 also comprises a drive arm, not shown, so as to simplify the reading of FIGS. 1 and 2. The drive arm is, on the one hand, fixed on the first opening 3a and, on the other hand, connected to the flexible element 9.

Thus, the drive arm is configured to secure the flexible element 9 to the first opening 3a.

Here, the drive arm is fixed directly to the first opening 3a.

Advantageously, the drive arm is connected, on the one hand, to the frame 15 of the first opening 3a and, more particularly, to the first lateral upright 15c of the frame 15 of the first opening 3a and, on the other hand, to the element flexible 9.

Alternatively, not shown, the drive arm is fixed to the first opening 3a by means of an intermediate element. Preferably, the intermediate element is a guide element, in particular a slide, in the sliding direction D.

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

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

Advantageously, the drive arm is disposed in the upper part of the first lateral upright 15c of the frame 15 of the first opening 3a.

Thus, the drive arm is configured to hang on the flexible element 9 disposed above the sleeping frame 4, in particular of the upper cross member 4a of the sleeping frame 4.

Preferably, the drive arm is fixed to an outer face of the first lateral upright 15c of the frame 15 of the first opening 3a. Thus, the drive arm is fixed to one face of the first lateral upright 15c of the frame 15 of the first opening 3a, oriented towards the outside of the window 2, in other words visible to the user. In this way, the fixing of the drive arm on the first lateral upright 15c of the frame 15 of the first opening 3a is facilitated with respect to a fixing of the driving arm on an internal area of the frame 15 of the first opening 3a, in particular located at the level of the sliding rail 11a of the upper crosspiece 4a of the frame 4, in the assembled configuration of window 2.

Advantageously, the drive arm is assembled with the first opening 3a on the inside of the frame 15 of the first opening 3a, in the assembled configuration of the window 2 relative to the building.

The inner side of the frame 15 of the first opening 3a is oriented towards the interior of the building, in the assembled configuration of window 2 relative to the building.

Advantageously, the flexible element 9 is connected to the drive arm, whatever the state of the locking elements of the fitting system, that is to say both in the locked state and in the unlocked state of the first opening 3a relative to the sleeping frame 4.

Thus, the flexible element 9 is permanently connected to the drive arm, in the assembled configuration of the motorized drive device 5 on the window 2.

In this way, the connection between the flexible element 9 and the drive arm is simplified and makes it possible to minimize the costs of obtaining the window 2.

In practice, the drive arm is fixed to the first lateral upright 15c of the frame 15 of the first opening 3a, configured to cooperate with the first lateral upright 4c of the fixed frame 4, when reaching the closed position of the first opening 3a relative to the sleeping frame 4.

In practice, the drive arm is fixed to the first lateral upright 15c of the frame 15 of the first opening 3a by means of fixing elements, not shown, in particular removable by means of a tool.

Here, the fastening elements of the drive arm on the first leaf 3a are screw fastening elements.

The type of elements for fixing the drive arm to the first leaf is not limiting and may be different. In particular, these may be elastic snap fasteners.

Advantageously, the drive arm is fixed to the frame 15 of the first opening 3a, following the installation of the first opening 3a inside the sleeping frame 4 and, in this case, also of the second opening 3b to the inside of the frame 4, installation during which the adjustments of the fitting system and of the sliding elements are implemented.

Thus, the adjustments of the fitting system and of the sliding elements can be implemented manually and conventionally, as for a window devoid of the motorized drive device 5.

Preferably, the drive arm is fixed to the frame 15 of the first opening 3a, following the electrical connection of the electromechanical actuator 6, either to a mains power supply network, or to a battery.

As a variant, not shown, the window 2 comprises a covering element. The covering element is configured to cover at least the drive arm.

In an exemplary embodiment, the covering element is configured to cover only the drive arm.

In another embodiment, the covering element is configured to cover the drive arm as well as part or all of the first lateral upright 15c of the frame 15 of the first opening 3a, in particular along the height of the frame 15, in the assembled configuration of window 2 relative to the building.

In practice, the covering element is fixed relative to the first opening 3a by means of fixing elements, following the assembly of the drive arm on the frame 15 of the first opening 3a.

Advantageously, the fixing elements of the covering element are configured to cooperate with the drive arm and / or with the first lateral upright 15c of the frame 15 of the first opening 3a.

The fastening elements of the covering element relative to the first opening 3a can be, in particular, fastening elements by elastic snap-fastening or by screwing.

In the embodiment illustrated in Figures 1 and 2, the motorized drive device 5 comprises a winding pulley 19 of the flexible element 9. The winding pulley 19 is rotated by the output shaft 8 of the electromechanical actuator 6.

A first end of the first strand 9a of the flexible element 9 is connected to a first part of the winding pulley 19. A first end of the second strand 9b of the flexible element 9 is connected to a second part of the pulley d winding 19.

Advantageously, the first end of each of the first and second strands 9a, 9b of the flexible element 9 is hooked respectively to the first part or to the second part of the winding pulley 19 by means of fixing elements, not shown. .

Thus, the first end of each of the first and second strands 9a, 9b of the flexible element 9 is respectively fixed directly to the first part or to the second part of the winding pulley 19.

In practice, the fastening elements of the end of each of the first and second strands 9a, 9b of the flexible element 9 are elements of the cable clamp type.

Here, these fixing elements are screws, in particular of the self-tapping type, which are screwed into the winding pulley 19, so as to fix the first and second strands 9a, 9b of the flexible element 9 by wedging between the head of the screws and the winding surface of the flexible element 9 of the winding pulley 19.

Here, the direction of winding, respectively unwinding, 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 winding, respectively of unwinding, of the second strand 9b of the flexible element 9 around the second part of the winding pulley 19.

Thus, during the movement of the first opening 3a relative to the sleeping frame 4 in a first sliding direction, in particular when moving from the closed position to an opening position of the first opening 3a relative to the sleeping frame 4, the first strand 9a of the flexible element 9 is wound around the first part of the winding pulley 19, while the second strand 9b of the flexible element 9 is wound around the second part of the winding pulley 19 .

In addition, during the movement of the first opening 3a relative to the sleeping frame 4 in a second sliding direction, in particular when moving from an open position to the closed position of the first opening 3a relative to the sleeping frame 4, the first strand 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 pulley winding 19.

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

In this way, the direction of 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 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 opening 3a relative to the sleeping 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 driving in rotation of the winding pulley 19 is determined by the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

Thus, the direction of 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 electromagnetic actuator 6.

Here, the direction of rotation of the winding pulley 19 is identical to the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

Control means of the electromechanical actuator 6 make it possible to control the movement by sliding of the first opening 3a relative to the sleeping frame 4. These control means comprise at least the electronic control unit 10. The electronic control unit 10 is configured to operate the electric motor 7 of the electromechanical actuator 6 and, in particular, allow the supply of electric energy to the electric motor 7.

Thus, the electronic control unit 10 controls, in particular, the electric motor 7, so as to open or close by sliding the first opening 3a relative to the sleeping frame 4.

In this way, the window 2 comprises the electronic control unit 10. More particularly, the electronic control unit 10 is integrated in the motorized drive device 5.

Advantageously, the motorized drive device 5 is a pre-assembled sub-assembly before mounting, in the example on the sleeping frame 4, which comprises at least the electromechanical actuator 6, the winding pulley 19, the element flexible 9 and the electronic control unit 10.

The order reception module can also allow the reception of orders transmitted by wired means.

The electronic control unit 10, the local control unit 12 and / or the central control unit 13 can be in communication with one or more sensors configured to determine, for example, a temperature, a hygrometry, a speed of wind, a measurement of an indoor or outdoor air quality parameter or a presence.

The central control unit 13 can also be in communication with a server 14, so as to control the electromechanical actuator 6 according to data made available remotely via a communication network, in particular an Internet network. can be connected to the server 14.

The electronic control unit 10 can be controlled from the local control unit 12. The local control unit 12 is provided with a control keyboard. The control keyboard of the local control unit 12 includes selection elements and, optionally, display elements.

Selection and display elements can also be performed using a touch screen.

The local control unit 12 can be a fixed or nomadic control point. A fixed control point corresponds to a control unit intended to be fixed on a facade of a building wall, on one face of the frame 15 of the first opening 3a of the window 2 or else on one face of the sleeping frame 4 of the window 2. A nomadic control point corresponds to a remote control.

The local control unit 12 makes it possible to directly control the electronic control unit 10 according to a selection made by the user.

The local control unit 12 allows the user to intervene directly on the electromechanical actuator 6 of the motorized drive device 5 via the electronic control unit 10 associated with this motorized drive device 5 , or to intervene indirectly on the electromechanical actuator 6 of the motorized drive device 5 via the central control unit 13.

The motorized drive device 5, in particular the electronic control unit 10, is preferably configured to execute orders for closing by sliding as well as opening by sliding the first opening 3a relative to the sleeping frame. 4, these control orders being able to be issued, in particular, by the local control unit 12 or by the central control unit 13.

The electronic control unit 10 is thus able to operate the electromechanical actuator 6 of the motorized drive device 5 and, in particular, allow the supply of electrical energy to the electromechanical actuator 6.

Here, and as illustrated in FIG. 1, the electronic control unit 10 is arranged inside the casing 17 of the electromechanical actuator 6.

The control means of the electromechanical actuator 6 include hardware and / or software means.

By way of nonlimiting example, the hardware means can comprise at least one microcontroller.

Advantageously, the local control unit 12 comprises a sensor measuring at least one parameter of the environment inside the building and integrated into this unit.

Thus, the local control unit 12 can communicate with the central control unit 13, and the central control unit 13 can control the electronic control unit 10 associated with the motorized drive device 5 as a function of data from of the sensor measuring the parameter of the environment inside the building.

Furthermore, the local control unit 12 can directly control the electronic control unit 10 associated with the motorized drive device 5 as a function of data coming from the sensor measuring the parameter of the environment inside the building.

By way of non-limiting examples, a parameter of the environment inside the building measured by the sensor integrated into the local control unit 12 is humidity, temperature, the level of carbon dioxide or the rate of an organic compound volatile in air.

Preferably, the activation of the local control unit 12 by the user has priority over the activation of the central control unit 13, so as to control the closing and the sliding opening of the first leaf 3a relative to the frame 4.

Thus, the activation of the local control unit 12 directly controls the electronic control unit 10 associated with the motorized drive device 5 according to a selection made by the user, possibly inhibiting a command order which can be sent by the central control unit 13 or by ignoring a value measured by a sensor measuring at least one parameter of the environment inside the building or outside the building, or a presence detection signal at inside the building.

The motorized drive device 5 can be controlled by the user, for example by receiving a control order corresponding to pressing on a selection element of the local control unit 12, such as a remote control or a fixed control point.

The motorized drive device 5 can also be controlled automatically, for example by receiving a control order corresponding to at least one signal from at least one sensor and / or to a signal from a clock. The sensor and / or the clock can be integrated into the local control unit 12 or the central control unit 13.

Advantageously, the motorized drive device 5 makes it possible to automatically slide the first opening 3a relative to the fixed frame 4 by sliding to a predetermined position, between the closed position and the maximum opening position. The sliding movement of the first opening 3a relative to the sleeping frame 4 to the predetermined position, in particular partial opening, is implemented following the reception of a control order issued by the local control unit 12, the central control unit 13 or a sensor.

Here, a movement by sliding of the first opening 3 relative to the sleeping frame 4 in the sliding direction D is implemented by supplying electrical energy to the electromechanical actuator 6, so as to unwind or wind the first and second strands 9a, 9b of the flexible element 9 around the first and second parts of the winding pulley 19.

Thus, the unwinding or winding of the first and second strands 9a, 9b of the flexible element 9 around the first and second parts of the winding pulley 19 is controlled by the supply of electrical energy to the electromechanical actuator 6 .

In practice, the supply of electrical energy to the electromechanical actuator 6 is controlled by a control order received by the electronic control unit 10 from the local control unit 12, from the central control unit 13 or a sensor.

Here, the motorized drive device 5, in particular the electromechanical actuator 6, is supplied with electrical energy from an electrical supply network. In such a case, the electromechanical actuator 6 comprises an electrical power cable, not shown, allowing it to be supplied with electrical energy from the sector's electrical power network.

Alternatively, the motorized drive device 5, in particular the electromechanical actuator 6, is supplied with electrical energy by means of a battery, not shown. In such a case, the battery can be recharged, for example, by a photovoltaic panel or any other energy recovery system, in particular, of the thermal type.

Here, the winding pulley 19 and the output shaft 8 of the electromechanical actuator 6 have the same axis of rotation, namely the axis of rotation X. In other words, the axis of rotation of the winding pulley 19 coincides with the axis of rotation of the output shaft 8 of the electromechanical actuator 6.

Thus, the winding pulley 19 is arranged in the extension of the output shaft 8 of the electromechanical actuator 6 and is rotated around the same axis of rotation X as the output shaft 8 of the electromechanical actuator 6.

Furthermore, the flexible element 9 forms a loop, called an open loop, between the first end of the first strand 9a, connected to the first part of the winding pulley 19, and the first end of the second strand 9b, connected to the second part of the winding pulley 19.

In this way, the first and second strands 9a, 9b of the flexible element 9 are connected to the winding pulley 19 and separated at the level of the first and second parts thereof.

In the embodiment illustrated in FIGS. 1 and 2, the electromechanical actuator 6 is fixed to the upper crosspiece 4a of the fixed frame 4 by means of fixing elements 28.

In addition, the winding pulley 19 is held on the upper crossmember 4a by means of these same fixing elements 28.

In practice, the fixing elements 28 of the electromechanical actuator 6 on the upper crosspiece 4a of the frame 4 include supports, in particular fixing brackets.

Advantageously, these supports are fixed to the upper crosspiece 4a of the fixed frame 4 by screwing.

In practice, each support of the fixing elements 28 comprises at least one hole, not shown, for the passage of a fixing screw. In an exemplary embodiment, each support may include two holes for the passage of a fixing screw.

In addition, a fixing screw passing through a through hole is screwed into the upper cross member 4a of the frame 4, in particular in a screw opening made in the upper cross member 4a of the frame 4. In practice, this fixing screw is self-tapping type.

Here, the fastening elements 28 of the electromechanical actuator 6 on the upper crosspiece 4a of the frame 4 include two supports. A first of these supports is assembled at a first end 6a of the electromechanical actuator 6. A second of these supports is assembled at a second end 6b of the electromechanical actuator 6. The first end 6a of the electromechanical actuator 6 is opposite at the second end 6b of the electromechanical actuator 6.

Advantageously, each support comprises at least one pin, not shown, configured to cooperate with a groove, not shown, formed in the upper crosspiece 4a of the fixed frame 4. In an exemplary embodiment, each support comprises two pins.

Thus, each support of the fastening elements 28 is oriented and positioned with respect to the upper crosspiece 4a of the frame 4.

Advantageously, the fixing of the electromechanical actuator 6, as well as of the winding pulley 19, on the supports of the fixing elements 28 is implemented by fixing parts, not shown, in particular by screwing.

Alternatively, not shown, the fastening parts of the electromechanical actuator 6, as well as of the winding pulley 19, on the supports of the fastening elements 28 are elastic labeling elements.

Here and as illustrated in FIGS. 1 and 2, the flexible element 9 of the motorized drive device 5 extends along the upper crosspiece 4a of the frame 4 from the first part of the winding pulley 19 to 'to the second part of the winding pulley 19.

Thus, such an arrangement of the flexible element 9 makes it possible to guarantee the movements by sliding of the first opening 3a relative to the sleeping frame 4, as well as the aesthetic appearance of the window 2.

Here and as illustrated in FIGS. 1 and 2, the flexible element 9 extends only on the side of the upper face of the upper cross member 4a, along at least part of the length U of the upper cross member 4a of the frame 4.

In practice, the motorized drive device 5 comprises at least two angular pulleys 35 which are spaced apart by a determined distance S along the length U of the upper cross member 4a of the frame 4.

The angular pulleys 35 are configured to guide the flexible element 9, in relation, in particular, to the winding pulley 19 and to the drive arm, in particular when the first leaf 3a is displaced relative to to the frame 4.

At least a first angular pulley 35 is disposed on a first side of the electromechanical actuator 6, that is to say on the side of the first end 6a of the electromechanical actuator 6. At least a second angle return pulley 35 is disposed on a second side of the electromechanical actuator 6, that is to say on the side of the second end 6b of the electromechanical actuator 6.

Here, the motorized drive device 5 comprises a pair of angular pulleys 35 disposed on the first side of the electromechanical actuator 6 distant from the determined spacing S relative to a pair of angular pulleys 35 arranged on the second side of the electromechanical actuator 6.

The number of angular pulleys is not limiting and may be different.

Each angular pulley 35 can be produced, for example, by a loose pulley, in other words mounted free in rotation, in particular on the upper crosspiece 4a of the frame 4, or by a fixed pulley, in other words integral with its axis, in particular fixed on the upper crosspiece 4a of the frame 4.

Each angular pulley 35 can be a pulley with a grooved wheel, generally called a sheave.

As illustrated in FIGS. 1 and 2, the electromechanical actuator 6 and the flexible element 9 are arranged in a trunk 31 arranged above the window 2, in particular extending above the upper crosspiece 4a of the sleeping frame 4.

Thus, the electromechanical actuator 6 and the flexible element 9 are concealed in the trunk 31, so as to guarantee the aesthetic appearance of the sliding window 2.

Similarly, the winding pulley 19 is disposed in the trunk 31 formed above the window 2.

Alternatively, not shown, the trunk 31 extends partially or completely in front of the sleeping frame 4, in the assembled configuration of the window 2 relative to the building. In this case, the trunk 31 extends at least in part projecting relative to the sleeping frame 4.

In such a case, the trunk 31 can either be disposed above the upper cross member 4a of the frame 4 or is disposed opposite the upper member 4a of the frame 4, that is to say in prominence towards the interior of the building, in the assembled configuration of window 2 relative to the building.

Advantageously, the window 2 comprises a hatch, not shown, for access to the motorized drive device 5 and, more particularly, to the electromechanical actuator 6 and to the flexible element 9, as well as to the winding pulley. 19.

Thus, the access hatch makes it possible to carry out a maintenance operation of the motorized drive device 5 and / or a repair operation of the latter.

In an exemplary embodiment, the access hatch extends along the entire length U of the upper cross member 4a of the frame 4.

As a variant, the access hatch extends only along part of the length U of the upper cross member 4a of the fixed frame 4.

Advantageously, the access hatch is provided in the trunk 31.

Alternatively, the access hatch is formed in the upper cross member 4a of the frame 4, in particular through the first sliding rail 11a of the upper crossmember 4a or between the first and second sliding rails 11a of the upper crossmember 4a.

Advantageously, the only opening 3a, among the first and second opening 3a, 3b, which can be slidably driven by the motorized drive device 5 is an inner opening of the window 2. The inner opening 3a is disposed on the inner side by report to the building, in the assembled configuration of window 2 in the building.

Thus, the flexible element 9 allowing the sliding opening of the first opening 3a relative to the sleeping frame 4 is kept inaccessible from outside the building and, more particularly, from the window 2, when the first opening 3a is in the closed position, as shown in Figure 1, or a secure ventilation position, as shown in Figure 2, relative to the frame 4.

The secure ventilation position, in other words a locked ajar position, is a position of the first opening 3a relative to the sleeping frame 4 in which the first opening 3a is ajar relative to the sleeping frame 4 and kept locked by a locking device 20. The locked ajar position is disposed between the open position and the closed position of the first opening 3a relative to the sleeping frame 4.

The locked ajar position is a partially open position of the first opening 3a relative to the sleeping frame 4, for which the frame 15 of the first opening 3a is spaced from the sleeping frame 4 by a predetermined distance, in particular of the order of a few centimeters .

In addition, in the case where the second opening 3b is movable manually, the latter can be moved by the user independently of the first opening 3a, in particular in the event of the absence of electrical energy supply to the motorized drive device 5 or failure of the motorized drive device 5.

The motorized drive device 5 makes it possible to automatically slide the first opening 3a relative to the sleeping frame 4 in the sliding direction D, by winding, respectively by unrolling, the first strand 9a of the flexible element 9 around the first part of the winding pulley 19 and unwinding, respectively by winding, the second strand 9b of the flexible element 9 around the second part of the winding pulley 19.

The motorized drive device 5 thus makes it possible to close and open in a motorized manner the first opening 3a relative to the fixed frame 4, by sliding in the sliding direction D.

Advantageously, in the event of a breakdown of the motorized drive device 5 or of a power cut to the motorized drive device 5, manual sliding, in particular by the user, of the first opening 3a relative to the sleeping frame 4 in the sliding direction D can be implemented, since the electromechanical actuator 6 is reversible or following the separation of the flexible element 9 relative to the first leaf 3a or following the separation of the drive arm from at the first opening 3a.

Furthermore, the use of the flexible element 9 to move the first opening 3a relative to the sleeping frame 4 makes it possible to minimize the costs of obtaining the motorized drive device 5, as well as to minimize the size of the device d motorized drive 5, in particular with respect to a belt.

We will now describe, with reference to Figures 3 to 5, the locking device 20 of the sliding window 2, according to a first embodiment.

For clarity of the drawings, the hatching is not shown in FIGS. 4 and 5.

The locking device 20 comprises a first sub-assembly 21 and a second sub-assembly 22.

The first sub-assembly 21 is fixed to the sleeping frame 4, in particular to the upper crosspiece 4a of the sleeping frame 4.

The first sub-assembly 21 includes a housing 23.

Here, the fixing of the first sub-assembly 21 and, more particularly, of the housing 23 relative to the sleeping frame 4 is implemented by means of fixing elements by screwing.

In the exemplary embodiment, the housing 23 of the first sub-assembly 21 is fixed relative to the sleeping frame 4 is carried out by means of two fixing screws 24, in particular of the self-tapping type, respectively passing through an opening in the housing 23 and screwing into the frame 4.

The number and type of fastening elements of the housing of the first subassembly relative to the sleeping frame are not limiting and may be different. These can be, in particular, elastic snap fastening elements.

Advantageously, the housing 23 comprises a stop 37. The stop 37 of the housing 23 bears on the upper cross member 4a of the frame 4 and, more particularly, on the underside of the upper member 4a of the frame 4, in the configuration assembly of the first sub-assembly 21 with the sleeping frame 4.

Here, the stop 37 of the housing 23 is produced in the form of a rim.

The second sub-assembly 22 is fixed on the first opening 3a, in particular on the upper cross member 15a of the frame 15 of the first opening 3a.

Advantageously, the second sub-assembly 22 comprises a support 25. The support 25 comprises at least one bottom wall 25a.

Here, the support 25 also includes two side walls 25b. The two side walls 25b of the support 25 are spaced from each other by a predetermined distance P and each connected to the bottom wall 25a of the support 25.

Here, the attachment of the second sub-assembly 22 and, more particularly, of the support 25 relative to the first opening 3a is implemented by means of fastening elements by screwing.

In the exemplary embodiment, the fixing of the support 25 of the second subassembly 22 relative to the first opening 3a is carried out by means of two fixing screws 26, in particular of the self-tapping type, respectively passing through an opening formed in the wall of bottom 25a of the support 25 and screwing into the first opening 3a.

The number and type of fastening elements of the support of the second subassembly relative to the first opening are not limiting and may be different. These may include, in particular, elastic snap fastening elements.

Here, the bottom wall 25a of the support 25 is supported on the upper cross member 15a of the frame 15 of the first leaf 3a and, more particularly, on the upper face of the upper cross member 15a of the frame 15 of the first leaf 3a, in the configuration assembly of the second sub-assembly 22 with the first opening 3a.

Advantageously, the second sub-assembly 22 is arranged near the first lateral upright 4c of the sleeping frame 4, ie the lateral upright 4c located on the right of the sleeping frame 4.

Thus, such positioning of the second sub-assembly 22 relative to the first lateral upright 4c of the sleeping frame 4 makes it possible to limit the deformations of the upper crosspiece 4a of the sleeping frame 4 supporting the second sub-assembly 22.

Here, the distance of the second sub-assembly 22 from the first lateral upright 4c of the sleeping frame 4 is within a range which can extend, for example, between three centimeters and ten centimeters.

The second sub-assembly 22 comprises a movable finger 27 around an axis of rotation Y and an elastic return element 30. The elastic return element 30 is configured to bring the mobile finger 27 to a rest position. The movable finger 27 is configured to cooperate with the first sub-assembly 21, during a movement of the first opening 3a relative to the sleeping frame 4, so as to be able to lock the first opening 3a relative to the sleeping frame 4 in the position ajar locked.

Here, the first sub-assembly 21 of the locking device 20, comprising at least the housing 23, is fixed on a fixed part of the window 2, in particular on the sleeping frame 4. In addition, the second sub-assembly 22 of the locking device 20, comprising at least the movable finger 27, is fixed on a movable part of the window 2, in particular on the first opening 3a.

Advantageously, the movable finger 27 is mounted in rotation around the axis of rotation Y relative to the support 25 of the second sub-assembly 22 by means of a pivot 32 and, more particularly, of a solid axis.

Thus, the locking device 20 comprises a single movable element which is the movable finger 27 of the second sub-assembly 22, so as to guarantee the reliability and robustness of the locking device 20.

In the exemplary embodiment, the pivot 32 is kept fixed relative to the support 25, in particular relative to the two side walls 25b of the support 25.

Here, the elastic return element 30 of the second sub-assembly 22 is a spring, in particular of torsion and which can be, for example, spiral.

Advantageously, the elastic return element 30 is located on an axis of rotation which is the same as the axis of rotation Y of the movable finger 27.

Here, the elastic return element 30 comprises a first arm 30a configured to cooperate with a housing 42 of the support 25 and a second arm 30b configured to cooperate with a housing 43 of the movable finger 27, in the assembled configuration of the second sub-assembly 22 of the locking device 20.

In the exemplary embodiment, the first arm 30a of the elastic return element 30 is produced in the form of an elbow, in particular with an angle value of the order of 90 °, and configured to cooperate with the housing 42 formed in one of the side walls 25b of the support 25, as illustrated in FIG. 5.

In addition, the second arm 30b of the elastic return element 30 is configured to cooperate with the housing 43 of the movable finger 27 produced in the form of a groove, as illustrated in FIG. 4.

The housing 23 comprises a first recess 33, a second recess 34 and a blocking stop 36 of the movable finger 27 of the second sub-assembly 22.

The first recess 33 and the second recess 34 are arranged on either side of the locking stop 36 in the sliding direction D of the first opening 3a relative to the sleeping frame 4.

In addition, each of the first and second recesses 33, 34 is configured to tilt the movable finger 27 from a first side C1 to a second side C2 relative to the axis of rotation Y of the movable finger 27, and vice versa, depending the direction of movement of the first opening 3a relative to the sleeping frame 4.

The movable finger 27 can thus switch between the first side C1 and the second side C2 with respect to the axis of rotation Y, when the movable finger 27 is disposed inside the first recess 33 or the second recess 34 of the housing 23 .

Thus, the locking device 20 makes it possible to lock the first opening 3a relative to the sleeping frame 4 in the locked ajar position, as well as to unlock the first opening 3a relative to the sleeping frame 4 from the locked ajar position, while minimizing the cost of obtaining the unlocking device

20.

In this way, the locking device 20 makes it possible to guarantee the ventilation of the building in a secure manner by a cracking of the first opening 3a relative to the sleeping frame 4, in particular by means of simple parts.

In addition, the electronic control unit 10 of the motorized drive device 5 makes it possible to control the movement of the first leaf 3a relative to the sleeping frame 4 to the locked ajar position.

In this way, reaching the ajar position locked by the motorized drive device 5 is implemented in a repeatable manner, while guaranteeing a frank stop of the first leaf 3a relative to the frame 4 via the device lock 20.

Furthermore, the locking device 20 makes it possible to prohibit, or at least delay, an attempted intrusion by an individual.

Such a locking device 20 also makes it possible to guarantee the aesthetic appearance of the window 2, since the latter is not very visible, in particular in an open position of the first opening 3a relative to the sleeping frame 4.

In addition, such a locking device 20 makes it possible to assemble and disassemble the first opening 3a relative to the sleeping frame 4, the movable finger 27 being advantageously retractable and, in particular, configured to be able to be housed inside the support. 25, in particular between the two side walls 25b of the support 25, during these assembly and disassembly operations.

Advantageously, in the assembled configuration of the locking device 20 in the window 2, each of the first and second recesses 33, 34 of the housing 23 has a height H configured to be greater than a length R of the movable finger 27, measured between the axis of rotation Y and a free end of the movable finger 27.

In this way, the height H of the first and second recesses 33, 34 of the housing 23 is sufficient so that the free end of the movable finger 27 is not in contact with a bottom wall of the first and second recesses 33, 34 of the housing 23.

Here, the respective height H of the first and second recesses 33, 34 of the housing 23 is identical.

The respective height of the first and second recesses of the housing is not limiting and may be different.

In addition, each of the first and second recesses 33, 34 of the housing 23 has a width L1, L2 configured to allow the tilting of the movable finger 27 from the first side C1 to the second side C2 relative to the axis of rotation Y of the movable finger. 27, and vice versa.

Here, the respective width L1, L2 of the first and second recesses 33, 34 of the housing 23 is different.

The respective width of the first and second recesses of the housing is not limiting and may, for example, extend up to one of the first and second vertical uprights of the sleeping frame.

Alternatively, not shown, the respective width L1, L2 of the first and second recesses 33, 34 of the housing 23 may be identical.

Advantageously, the locking device 20 is independent of the motorized drive device 5.

Thus, the first and second sub-assemblies 21, 22 of the locking device 20 can be assembled respectively on the sleeping frame 4 and on the first opening 3 a of the sliding window 2 whatever the motorized driving device 5 configured to drive in displacement at least the first opening 3a.

Advantageously, in the resting position of the movable finger 27, the movable finger 27 is inclined by a predetermined inclination value a relative to the bottom wall 25a of the support 25 in the direction of the second side C2 relative to the axis of rotation Y, as illustrated in figure 4.

Thus, by providing that the inclination value a is different from 90 °, the movable finger 27 is in a position different from a vertical position relative to the bottom wall 25a of the support 25.

In this way, this inclination of the movable finger 27 in its rest position makes it possible to guarantee the entry of the movable finger 27 inside the first recess 33 of the housing 23, during a movement towards the closed position of the first opening 3a relative to the sleeping frame 4.

In addition, this inclination of the movable finger 27 in its rest position makes it possible to guarantee the assembly of the first opening 3a with the sleeping frame 4.

Here, the predetermined inclination value a of the movable finger 27 relative to the bottom wall 25a of the support 25 is comprised in a range extending between 10 ° and 80 ° and, preferably, of the order of 25 °.

Preferably, the housing 23 of the first sub-assembly 21 comprises a holding area 38 of the movable finger 27 in a tilted position relative to the bottom wall 25a of the support 25. In addition, the holding area 38 of the movable finger 27 is disposed between the locking stop 36 and the second recess 34 of the housing 23, in the direction of movement towards the closed position of the first opening 3a relative to the sleeping frame 4.

Advantageously, the vertical component of the forces applied by the movable finger 27 of the second sub-assembly 22 on the first sub-assembly 21, in particular on the locking stop 36 and on the holding zone 38 of the first sub-assembly 21, tends to push the first opening 3a towards the sliding rail of the lower cross member of the fixed frame 4, ie downwards.

Thus, this vertical component of the forces of the movable finger 27 of the second sub-assembly 22 on the first sub-assembly 21 makes it possible to limit the possibility of unhinging the first opening 3a relative to the sleeping frame 4.

Preferably, the second sub-assembly 22 comprises an unlocking cable 39. In addition, one end of the unlocking cable 39 is fixed to the movable finger 27.

Thus, the unlocking cable 39 makes it possible to release the movable finger 27 relative to the locking stop 36, so as to unlock the first leaf 3a relative to the sleeping frame 4 from the locked ajar position, in other words to allow the displacement of the first opening 3a relative to the sleeping frame 4.

Here, the unlocking of the first opening 3a with respect to the sleeping frame 4 from the locked ajar position is implemented manually, in particular by the user, by pulling on the unlocking cable 39.

In this way, the unlocking cable 39 allows the first leaf 3a to be unlocked relative to the fixed frame 4 from the locked ajar position, in particular in the event of a malfunction of the locking device 20, for example, in the event of mechanical jamming. movable finger 27.

The locking device 20 can thus be manually deactivated by an emergency control implemented by means of the unlocking cable 39.

In an exemplary embodiment, the fixing of the unlocking cable 39 relative to the movable finger 27 is implemented by the passage of the unlocking cable through an opening 29 formed in the movable finger 27, as shown in FIG. 3 , and by means of a knot, not shown.

As a variant, not shown, the fixing of the unlocking cable 39 with respect to the movable finger 27 is implemented by an element of the cable clamp type. Such an element of the cable clamp type can be produced, for example, by means of a screw, in particular of the self-tapping type, which is screwed into the movable finger 27, so as to fix the unlocking cable 39 by wedging between a head of the screw and a surface of the movable finger 27.

The type of element for fixing the release cable with respect to the movable finger is not limiting and may be different.

Advantageously, the unlocking cable 39 is disposed inside a housing 41 of the upper cross member 4a of the fixed frame 4 and configured to be actuated from a determined location at the level of the second lateral upright 15c of the frame 15 of the first opening 3a, or at the lateral upright 15c of the frame 15 located on the left of the first opening 3a.

When traction is exerted on the unlocking cable 39, the movable finger 27 is driven in rotation about the axis of rotation Y, in particular in the direction of the first side C1 relative to the axis of rotation Y.

Thus, the tensile force exerted on the unlocking cable 39 is greater than the force of the elastic return element 30.

In this way, following the disengagement of the movable finger 27 relative to the locking stop 36 of the housing 23, the locked ajar position of the first leaf 3a relative to the sleeping frame 4 is released.

In such a case, a manual movement of the first opening 3a relative to the sleeping frame 4 can be implemented, in particular by continuing to pull on the unlocking cable 39.

Advantageously, the support 25 of the second sub-assembly 22 comprises a guide element 44 of the unlocking cable 39.

In the exemplary embodiment, the guide element 44 is a rod held fixed relative to the support 25, in particular relative to the two side walls 25b of the support 25.

Here, the unlocking cable 39 is disposed between the guide element 44 and the bottom wall 25a of the support 25.

A description will now be given, with reference to FIGS. 6 to 12, of a method for controlling the operation of the motorized drive device 5 of the sliding window 2 for a building according to the invention.

For clarity of the drawings, the hatching is not shown in FIGS. 6 to 12.

The method for controlling the operation of the motorized drive device 5 includes a first control step, so as to position the first opening 3a relative to the sleeping frame 4 in the locked ajar position.

Here, the first control step is implemented by issuing a control command to the electronic control unit 10 of the motorized drive device

5, in particular by means of one of the local or central control units 12 or even of a sensor.

The first order step can thus be carried out manually, in particular by the user, or automatically.

Following the first control step, the method comprises a first step of moving the first opening 3a relative to the sleeping frame 4 from the closed position to an open position, in which the movable finger 27, in particular the free end of the movable finger 27, is positioned beyond the locking device 20 in the sliding direction D of the first opening 3a relative to the fixed frame 4.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the first movement step, is illustrated by the arrow F1 in FIG. 3.

Here, the first step of moving the first opening 3a relative to the sleeping frame 4 is implemented by the electrical activation of the electromechanical actuator

6.

When the first opening 3a is in the closed position relative to the sleeping frame 4, the movable finger 27 of the second sub-assembly 22 is disposed inside the second recess 34 of the housing 23 and, in particular, in its rest position , as shown in Figure 6.

During the movement of the first opening 3a relative to the sleeping frame 4 from the closed position to the open position, the movable finger 27 follows the profile of the shapes of the housing 23, in particular the second recess 34, the area of holding 38, the locking stop 36, then the first recess 33, and then the profile of the lower face of the upper cross member 4a of the frame 4.

In addition, during the first displacement step, the movable finger 27 remains inclined relative to the bottom wall 25a of the support 25 in the direction of the second side C2 relative to the axis of rotation Y.

Following the first movement step, the method comprises a second step of moving the first opening 3a relative to the sleeping frame 4 from the open position to the closed position.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the second movement step, is illustrated by the arrow F2 in FIG. 3.

Here, the second step of moving the first opening 3a relative to the sleeping frame 4 is implemented by the electrical activation of the electromechanical actuator

6.

During the movement of the first opening 3a relative to the sleeping frame 4 from the open position to the closed position, the movable finger 27 follows the profile of the underside of the upper cross member 4a of the sleeping frame 4, as illustrated in the FIG. 7, and then the profile of the shapes of the housing 23, in particular the first recess 33, the locking stop 36, then the holding zone 38.

In addition, during the second displacement step, the movable finger 27 is inclined relative to the bottom wall 25a of the support 25 in the direction of the second side C2 relative to the axis of rotation Y, from the open position. until the first recess 33 of the housing 23 is reached, as illustrated in FIG. 7. When the first recess 33 of the housing 23 is reached, the movable finger 27 switches from an inclined position relative to the wall of bottom 25a of the support 25 in the direction of the second side C2 relative to the axis of rotation Y in its rest position, under the force of the elastic return element 30, as illustrated in FIG. 8. Then, the finger mobile 27 switches from its rest position to an inclined position relative to the bottom wall 25a of the support 25 in the direction of the first side C1 relative to the axis of rotation Y, as illustrated in FIG. 9.

Following the second displacement step, the method comprises a step of stopping the first opening 3a relative to the sleeping frame 4 in a position where the movable finger 27, in particular the free end of the movable finger 27, is located in the holding zone 38 of the housing 23, as illustrated in FIG. 10.

Here, the step of stopping the first opening 3a relative to the sleeping frame 4 is implemented by the electrical deactivation of the electromechanical actuator 6.

When the first opening 3a is stopped relative to the sleeping frame 4, the movable finger 27 is held in the inclined position relative to the bottom wall 25a of the support 25 in the direction of the first side C1 relative to the axis of rotation Y by means of the holding zone 38 of the housing 23, as illustrated in FIG. 10.

Following the stopping step, the method comprises a third step of moving the first opening 3a relative to the sleeping frame 4 to the locked ajar position of the first opening 3a relative to the sleeping frame 4, in other words up to pressing the movable finger 27 against the locking stop 36 of the housing 23.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the third movement step, is illustrated by the arrow F1 in FIG. 3.

Here, the third step of moving the first opening 3a relative to the sleeping frame 4 is implemented from the stopped position, in which the movable finger 27 is positioned in the holding zone 38 of the housing 23.

Here, the third step of moving the first opening 3a relative to the sleeping frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

During the movement of the first opening 3a relative to the sleeping frame 4 from the stopped position to the locked ajar position, the movable finger 27 follows the profile of the holding zone 38 of the housing 23.

When the first opening 3a reaches the locked ajar position relative to the sleeping frame 4, the movable finger 27 is held in the inclined position relative to the bottom wall 25a of the support 25 in the direction of the first side C1 relative to the axis of rotation Y by means of the locking stop 36 of the housing 23, as illustrated in FIG. 11.

Thus, pressing the movable finger 27 against the blocking stop 36 of the housing 23 makes it possible to prevent the displacement of the first opening 3a relative to the sleeping frame 4 towards an open position of the first opening 3a relative to the sleeping frame

4.

Advantageously, the steps of the control method described above are implemented automatically by the motorized drive device 5 and, more particularly, by the electronic control unit 10, so as to reach the locked ajar position of the first leaf 3a relative to the sleeping frame 4.

Advantageously, after reaching the locked ajar position of the first opening 3a relative to the sleeping frame 4, the method comprises a second control step, so as to deactivate the locking device 20.

Here, the second control step is implemented by issuing a control command to the electronic control unit 10 of the motorized drive device

5, in particular by means of one of the local or central control units 12 or even of a sensor.

The second control step can thus be implemented manually, in particular by the user, or automatically.

Following the second control step, the method comprises a fourth step of moving the first opening 3a relative to the sleeping frame 4 from the locked ajar position to the closed position.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the fourth movement step, is illustrated by the arrow F2 in FIG. 3.

Here, the fourth step of moving the first opening 3a relative to the sleeping frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

During the movement of the first opening 3a relative to the sleeping frame 4 from the locked ajar position to the closed position, the movable finger 27 follows the profile of the shapes of the housing 23, in particular the holding zone 38, then the second recess 34.

In addition, during the fourth displacement step, the movable finger 27 is inclined relative to the bottom wall 25a of the support 25 in the direction of the first side C1 relative to the axis of rotation Y, from the ajar position. locked until the second recess 34 of the housing 23 is reached. When the second recess 34 of the housing 23 is reached, the movable finger 27 switches from an inclined position relative to the bottom wall 25a of the support 25 in direction of the first side C1 relative to the axis of rotation Y in its rest position, under the force of the elastic return element 30.

Thus, the first opening 3a returns to the initial position relative to the sleeping frame 4, as well as the movable finger 27 relative to the bottom wall 25a of the support 25, as before the first step of displacement.

In this way, the first opening 3a is unlocked relative to the sleeping frame 4.

Advantageously, the fourth step of the control method is implemented automatically by the motorized drive device 5 and, more particularly, by the electronic control unit 10, so as to deactivate the locking device 20.

Advantageously, after reaching the locked ajar position, the method may include a step of unlocking the locking device 20 by means of the unlocking cable 39.

Here, the step of unlocking the first opening 3a relative to the sleeping frame 4 is carried out manually, in particular by the user.

When the first opening 3a is released relative to the sleeping frame 4, a force is exerted on the unlocking cable 39 by pulling on it, so that the movable finger 27 slides along the locking stop 36 of the housing 23 and disengages from this locking stop 36, as illustrated in FIG. 12.

Following the unlocking of the first opening 3a relative to the sleeping frame 4, manual movement of the first opening 3a relative to the sleeping frame 4 to an open position is necessary, preferably by pulling on the unlocking cable 39.

Preferably, after reaching the locked ajar position of the first opening 3a relative to the sleeping frame 4, the method comprises a step of monitoring the position of the first opening 3a relative to the sleeping frame 4.

Thus, the monitoring step makes it possible to detect a displacement of the first opening 3a relative to the sleeping frame 4.

Here, the monitoring step is implemented by at least one position detection sensor of an output shaft of the electric motor 7 of the electromechanical actuator 6.

In the exemplary embodiment, during the movement of the first opening 3a relative to the sleeping frame 4, the output shaft of the electric motor 7 of the electromechanical actuator 6 is driven in rotation through the motorized drive device 5.

Thus, the displacement of the first opening 3a relative to the sleeping frame 4 is determined by the position detection sensor of the output shaft of the electric motor.

7.

Here, the position detection sensor of the output shaft of the electric motor 7 is a Hall effect sensor.

As a variant, the monitoring step is implemented by at least one position detection sensor of an output shaft of the electromechanical actuator 6.

As a variant, the monitoring step is implemented by at least one position detection sensor of the first opening 3a relative to the sleeping frame 4.

The type and number of position detection sensors are not limiting and may be different. It can be, in particular, one or more optical sensors.

Here, the monitoring step is implemented through the electronic control unit 10 of the motorized drive device 5.

Preferably, following the detection of a displacement of the first opening 3a relative to the sleeping frame 4 during the monitoring step, the method comprises a step of determining an intrusion attempt.

Advantageously, in the case where a control order is issued from one of the control units 12, 13 or from a sensor, the step of determining an intrusion attempt is inhibited.

Thus, the displacement of the first opening 3a relative to the sleeping frame 4 detected during the monitoring step is considered to be a displacement implemented voluntarily by a user.

In this way, the monitoring step makes it possible to determine whether the displacement of the first opening 3a relative to the sleeping frame 4 is carried out manually.

Advantageously, an intrusion attempt is determined in the case where the length of movement of the first opening 3a relative to the sleeping frame 4 is greater than a predetermined threshold value M during a predetermined period of time T.

Thus, such parameters Μ, T for the characterization of the displacement of the first opening 3a with respect to the detected sleeping frame 4 makes it possible to avoid inadvertently determining an intrusion attempt.

By way of nonlimiting example, an intrusion attempt is determined in the case where the length of the movement of the first opening 3a relative to the sleeping frame 4 is greater than one centimeter during a period of time of a value of a minute.

Here, the step of determining an intrusion attempt is implemented through the electronic control unit 10 of the motorized drive device 5.

Advantageously, in the case where an intrusion attempt has been determined during the step of determining an intrusion attempt, the method comprises a fifth step of displacement of the first opening 3a relative to the sleeping frame 4 from the half open position locked to the closed position.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the fifth movement step, is illustrated by the arrow F2 in FIG. 3.

Here, the fifth step of moving the first opening 3a relative to the sleeping frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

This fifth displacement step is implemented in a similar manner to the fourth displacement step.

Advantageously, the fifth step of the control method is implemented automatically by the motorized drive device 5 and, more particularly, by the electronic control unit 10, so as to place the first opening 3a relative to the frame standing 4 in the closed position, itself locked by another locking device, not shown.

Thus, the window 2 and, more particularly, the building is protected against attempted intrusion by closing the first opening 3a relative to the sleeping frame 4 by means of the motorized drive device 5

Prior to the fifth displacement step, the method comprises a step of awakening the electromechanical actuator 6 from a standby state.

Advantageously, in the case where an intrusion attempt has been determined during the step of determining an intrusion attempt, the method may also include a step of transmitting information to an alarm system, not represented.

Thus, the alarm system can trigger a siren, so as to emit an audible signal, emit a notification to at least one mobile terminal, for example to a smartphone, so as to inform one or more users, and / or emit a notification to the central control unit, so as to control the closing of the screen of each blackout device, for example of each roller shutter, each shutter and / or each external venetian blind.

Advantageously, after reaching the locked ajar position of the first opening 3a relative to the sleeping frame 4, the electronic control unit 10 of the motorized drive device 5 is configured to determine whether a manual movement of the first opening 3a by relative to the sleeping frame 4 corresponds to an intrusion attempt or to a command to unlock the first opening 3a relative to the sleeping frame 4 by means of the unlocking cable 39, through the step of monitoring the position of the first opening 3a relative to the sleeping frame 4.

In an exemplary embodiment, if the length of the manual movement of the first opening 3a relative to the sleeping frame 4 is greater than or equal to a predetermined threshold value, which may be, for example, half the length L38 of the holding zone 38 of the housing 23, then the electronic control unit 10 of the motorized drive device 5 determines an intrusion attempt and triggers the implementation of the fifth step of displacement of the first opening 3a relative to the sleeping frame 4. Furthermore , if the length of the manual movement of the first leaf 3a relative to the sleeping frame 4 is less than the predetermined threshold value, then the electronic control unit 10 of the motorized drive device 5 determines an unlocking command for the first leaf 3a by relative to the sleeping frame 4 by means of the unlocking cable 39 and inhibits the implementation of the fifth step of displacement of the first opening 3a relative to the sleeping frame 4.

Advantageously, the step of monitoring the position of the first opening 3a relative to the sleeping frame 4 is implemented after the expiration of a predetermined period of time, from the moment of reaching the position ajar locked of the first opening 3a relative to the sleeping frame 4.

Thus, the method makes it possible to avoid detection of an untimely intrusion attempt generated by a manual movement of the first leaf 3a relative to the sleeping frame 4 in a limited time interval, after reaching the locked ajar position of the first opening 3a relative to the sleeping frame 4.

As a non-limiting example, the predetermined period of time can be of the order of two minutes.

Advantageously, during the step of monitoring the position of the first opening 3a relative to the sleeping frame 4, the determination of an intrusion attempt or an unlocking command is, moreover, implemented by the determination the sequence of manual movement of the first leaf 3a relative to the sleeping frame 4.

Here, an intrusion attempt is determined by the electronic control unit 10 of the motorized drive device 5, when the manual movement of the first leaf 3a relative to the sleeping frame 4 is implemented, firstly, towards an open position then, in a second step, towards the closed position. In addition, an unlocking command is determined by the electronic control unit 10 of the motorized drive device 5, when the manual movement of the first leaf 3a relative to the sleeping frame 4 is implemented only towards an open position.
