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 includes a drive arm 18.

The drive arm 18 is, on the one hand, fixed on the first opening 3a and, on the other hand, connected to the flexible element 9.

Preferably, the drive arm 18 is fixed, 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 opening 3a is simplified and makes it possible to minimize the costs of obtaining the window 2.

Advantageously, the drive arm 18 is arranged in the upper part of the first lateral upright 15c of the frame 15 of the first opening 3a.

Preferably, the drive arm 18 is fixed on an outer face of the first lateral upright 15c of the frame 15 of the first opening 3a.

Thus, the drive arm 18 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 18 on the first lateral upright 15c of the frame 15 of the first opening 3a is facilitated compared to a fixing of the driving arm 18 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 the window 2.

Here, the fastening elements of the drive arm 18 on the first opening 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. It can be, in particular, elastic snap fastening elements.

Advantageously, the drive arm 18 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 l 'interior of the frame 4, installation during which are implemented the adjustments of the fitting system and the sliding elements.

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 18 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 18.

In an exemplary embodiment, the covering element is configured to cover only the drive arm 18.

In another embodiment, the covering element is configured to cover the drive arm 18 as well as a 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 18 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 18 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.

Preferably, the cross member 47 comprises a slide 36. In addition, the shuttle 45 is configured to slide inside the slide 36 of the cross member 47.

Thus, the movements of the shuttle 45, during the drive of the flexible element 9, are guided inside the slide 36 of the crosspiece 47.

In the embodiment illustrated in Figures 1 to 3, 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 46.

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 46 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 46 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 cross member 47, which comprises at least the electromechanical actuator 6, the winding pulley 19, the flexible element 9 and the electronic control unit 10.

The motorized drive device 5 is controlled by a control unit. The control unit can be, for example, a local control unit 12.

The local control unit 12 can be connected in wired or wireless connection with a central control unit 13. The central control unit 13 controls the local control unit 12, as well as other similar local control units and distributed throughout the building.

The electronic control unit 10 also comprises a module for receiving orders, in particular radioelectric orders sent by an order transmitter, such as the local control unit 12 or the central control unit 13, these orders being intended to control the motorized drive device 5. 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.

By way of non-limiting examples, the selection elements can be push buttons or sensitive keys, the display elements can be light-emitting diodes, an LCD display (acronym of the English expression "Liquid Crystal Display" ) or TFT (acronym of the English expression "Thin Film Transistor"). 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 exemplary embodiment illustrated in FIGS. 1 to 3, the electromechanical actuator 6 is fixed to the crosspiece 47 by means of fixing elements 28.

In addition, the winding pulley 19 is held on the cross-member 47 by means of these same fixing elements 28.

In practice, the fastening elements 28 of the electromechanical actuator 6 on the cross-member 47 comprise supports, in particular fixing brackets.

Advantageously, these supports are fixed to the crosspiece 47 of the fixed frame 4 by screwing.

In practice, each support of the fixing elements 28 comprises at least one hole 48 for the passage of a fixing screw. In this exemplary embodiment, each support comprises two holes 48 for the passage of a fixing screw.

In addition, each fixing screw passing through one of the through holes 48 is screwed into a lardon, not shown, held in a groove 49 of the crossbar 47, in particular in a screw opening made in the lardon.

Here, the fastening elements 28 of the electromechanical actuator 6 on the crosspiece 47 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 of the fastening elements 28 comprises at least one pin, not shown, configured to cooperate with the groove 49 formed in the crosspiece 47. In an exemplary embodiment, each support comprises two pins.

Thus, each support is oriented and positioned relative to the crosspiece 47.

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.

As a variant, not shown, the fastening parts of the electromechanical actuator 6, as well as of the winding pulley 19, on the supports are elastic locking elements.

Here and as illustrated in FIGS. 1 to 3, the flexible element 9 of the motorized drive device 5 extends along the upper cross member 4a of the frame 4 and, more particularly, of the cross member 47, from the first part of the winding pulley 19 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.

Advantageously, the cross member 47 is fixed to the upper cross member 4a of the fixed frame 4 by means of fixing elements, not shown.

In this exemplary embodiment, the fastening elements of the cross member 47 on the upper cross member 4a of the fixed frame 4 are fastening elements by screwing.

The type of fastening elements of the cross member on the upper cross member of the frame are not limiting and may be different. These can be, in particular, elastic snap fastening elements.

As a variant, not shown, the electromechanical actuator 6 is fixed to the upper crosspiece 4a of the fixed frame 4 by means of the fixing elements 28.

Here and as illustrated in FIGS. 1 to 3, the flexible element 9 extends only at the level of the upper cross member 4a of the fixed frame 4, following at least part of the length V of the cross member 47.

In practice, the motorized drive device 5 comprises at least two angular pulleys 35 distant by a spacing determined along the length V of the crosspiece 47.

The angle deflection pulleys 35 are configured to guide the flexible element 9, with respect, in particular, to the winding pulley 19 and to the drive arm 18, in particular when the first opening 3a is moved by relative 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 angle deflection pulleys 35 disposed on the first side of the electromechanical actuator 6 distant from the spacing determined with respect to a pair of angle deflection pulleys 35 disposed on the second side of the electromechanical actuator 6.

In this exemplary embodiment, the angular pulleys 35 disposed on the second side of the electromechanical actuator 6 are masked by a first locking device 20.

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 to 3, the electromechanical actuator 6 and the flexible element 9 are arranged inside the cross member 47, configured to form a trunk and formed above the window 2, in particular s 'extending at least in part above the upper cross member 4a of the frame 4.

Thus, the electromechanical actuator 6 and the flexible element 9 are concealed inside the cross member 47, so as to guarantee the aesthetic appearance of the sliding window 2.

Likewise, the winding pulley 19 is disposed inside the cross-member 47 formed above the window 2.

The cross-member 47 can extend 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 cross member 47 extends at least in part projecting relative to the frame 4.

In such a case, the cross-member 47 can either be arranged above the upper cross-member 4a of the sleeping frame 4 or is disposed opposite the upper cross-member 4a of the sleeping 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 cross-member 47 comprises a cover, not shown, configured to access the motorized drive device 5 and, more particularly, the electromechanical actuator 6 and the flexible element 9, as well as the winding pulley 19.

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

In an exemplary embodiment, the cover extends along the entire length V of the cross member 47.

As a variant, the cover extends only along part of the length V of the crosspiece 47.

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 the first locking device 20 The locked ajar position is disposed between the open position and the closed position of the first leaf 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 further following the separation of the flexible element 9 relative to the first opening 3a or following the separation of the drive arm 18 relative to 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.

As indicated in dotted lines in FIG. 1, the window 2 also includes a second locking device 21 for locking the first opening 3a relative to the sleeping frame 4 in the closed position and thus passing it into the closed locked position.

In addition, the window 2 comprises a control device 22 for controlling the second locking device 21, as illustrated in FIG. 1. The control device 22 is configured, on the one hand, to cooperate with the second locking device 21 and, on the other hand, to be actuated by means of the flexible element 9 and, more particularly by means of the shuttle 45, when the electromechanical actuator 6 is electrically activated.

Advantageously, the second locking device 21 is part of the fitting system, mentioned above, of the window 2.

Preferably, the drive arm 18 supports the control device 22.

Thus, the drive arm 18 and the control device 22 form an integral mechanical assembly.

As shown in FIG. 4, the control device 22 advantageously comprises a drive element 30. This drive element 30 is, on the one hand, connected to the shuttle 45 and, on the other hand, mounted in rotation by relative to the drive arm 18.

Thus, the drive element 30 has a clearance with respect to the drive arm 18 and, more particularly, with respect to a casing 38 of the drive arm 18.

Advantageously, the trunk, formed by the cross member 47 and its cover, comprises a slot 24 configured to allow the passage of an upper part of the drive arm 18, during a movement of the drive arm 18 relative to the frame frame 4 in the sliding direction D, as shown in Figure 4.

Thus, the drive arm 18 can be driven in displacement relative to the trunk, in the assembled configuration of window 2, while being connected to the drive element 30 of the control device 22.

In this way, the upper part of the drive arm 18 is configured to move inside the slot 24 made in the trunk.

Furthermore, a lower part of the drive arm 18 is arranged outside the trunk.

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

Thus, the drive arm 18 and the second locking device 21 are arranged as close as possible to the flexible element 9, since the flexible element 9 extends inside the cross-member 47.

Preferably, the second locking device 21 is disposed inside the first lateral upright 15c of the frame 15 of the first opening 3a.

Advantageously, the second locking device 21 comprises at least one housing, a shaft, commonly called a square, a drive bell and a bolt, not shown. The drive bell includes a housing. A first end of the shaft is disposed inside the housing of the drive bell. The bolt is configured to cooperate with a hole in the rod of the cremone bolt.

Here, when the shaft of the second locking device 21 is rotated by the control device 22, either for locking the first opening 3a relative to the frame 4 or for unlocking the first opening 3a relative to the sleeping frame 4, the drive bell is rotated inside the housing of the second locking device 21, then the bolt of the second locking device 21 is driven in translation, so as to move the rod the cremone bolt along the lateral upright 15c of the frame 15 of the first opening 3a, in particular in a vertical direction, in the assembled configuration of the window 2 relative to the building.

Advantageously, the control device 22 comprises a mechanism for actuating the second locking device 21 configured to rotate the shaft of the second locking device 21, when the flexible element 9 is driven by the electromechanical actuator 6.

Thus, the actuation mechanism of the control device 22 is configured to transform the translational movement of the flexible element 9 applied to the drive arm 18 via the shuttle 45, in particular by the element of drive, during the electrical activation of the electromechanical actuator 6, in a rotational movement of the shaft of the second locking device 21, during locking or unlocking of the first opening 3a relative to the sleeping frame 4.

Advantageously, the actuation mechanism of the control device 22 can be implemented by means of one or more lever arms and / or by one or more pinions.

We will now describe, with reference to FIGS. 4 to 12, in more detail the arrangement between the motorized drive device 5 and the first locking device 20 of the sliding window 2, according to one embodiment.

The first locking device 20 comprises a movable arm 23 around a first axis of rotation Y1.

Advantageously, the movable arm 23 is configured to move relative to a fixed part of the window 2 around the first axis of rotation Y1.

Here, the movable arm 23 is configured to move relative to the cross member 47 around the first axis of rotation Y1.

In this exemplary embodiment, the movable arm 23 is assembled on the cross-member 47 by means of an assembly element 25.

Here, the assembly element 25 comprises an opening 26 inside which is arranged a rotation shaft 27, so as to allow a rotational movement of the movable arm 23 around the first axis of rotation Y1.

Thus, the movable arm 23 is mounted in rotation relative to the assembly element 25 around the first axis of rotation Y1, by means of a pivot connection.

Advantageously, the assembly element 25 is fixed to the cross-member 47 by means of fixing elements, not shown.

Here, the assembly element 25 is configured to fix the first locking device 20 on a fixed part of the window 2, in particular the crosspiece 47.

Here, the fastening elements of the connecting element 25 on the cross member 47 comprise positioning elements inside the groove 49 of the cross member 47, such as, for example, guide pins, as well as screw. Each fixing screw is configured to pass through a through hole made in the cross member 47 and to be screwed into a fixing hole in the connecting element 25.

The type of elements for fixing the assembly element to the cross-member is not limiting and may be different. These can be, in particular, elastic snap fastening elements.

In this embodiment, the first locking device 20 is supported on the cross member 47. And, more particularly, a wall of the assembly element 25 of the first locking device 20 is supported on a wall of the cross member 47.

Here, the assembly element 25 of the first locking device 20 is produced in the form of a stirrup.

Advantageously, the first locking device 20 comprises a first elastic return element, not shown, disposed between the movable arm 23 and the assembly element 25.

Thus, the first elastic return element makes it possible to guarantee that the mobile arm 23 is kept in a rest position relative to the assembly element 25 and, more particularly, relative to the cross member 47.

Here, the first elastic return element is a spring, in particular of the pin type.

The type of elastic return element between the movable arm and the assembly element is not limiting and may be different. It can be, in particular, a torsion spring, for example with spirals.

Advantageously, the first elastic return element is located on the same axis of rotation Y1 as that of the movable arm 23.

In such a case, the movable arm 23 is in abutment against a stop, not shown, of the assembly element 25.

As a variant, not shown, the mobile arm 23 is configured to move relative to the sleeping frame 4 around the first axis of rotation Y1 and, more particularly, relative to the upper cross member 4a of the sleeping frame 4.

The drive arm 18 is configured to cooperate with the movable arm 23 of the first locking device 20.

Here, the shuttle 45 is also configured to cooperate with the movable arm 23 of the first locking device 20.

The movable arm 23 is configured to hold the drive arm 18 and, more particularly the casing 38 of the drive arm 18, between the locked ajar position and the closed position of the first leaf 3a relative to the frame 4, following the crossing of the locked ajar position, when the first opening 3a moves relative to the frame 4 from an open position to the closed position.

The first locking device 20 comprises a device 29 for releasing the movable arm 23 relative to the drive arm 18.

The release device 29 is configured to be activated, following the locking of the first opening 3a relative to the sleeping frame 4 in the closed position, by means of the second locking device 21.

Thus, the first locking device 20 makes it possible to lock the first opening 3a relative to the sleeping frame 4 in the locked ajar position, by means of the motorized driving device 5.

In this way, the first 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 unlocking of the first opening 3a relative to the sleeping frame 4 in connection with the first locking device 20 is implemented by means of the motorized drive device 5 configured to generate a displacement of the first opening 3a relative to the frame frame 4 passing through the closed and locked position of the first leaf 3a with respect to the frame 4, by means of the second locking device 21.

In this way, the unlocking of the first opening 3a relative to the sleeping frame 4 is implemented only by means of the motorized driving device 5.

Furthermore, the electronic control unit 10 of the motorized drive device 5 makes it possible to control the movement of the first opening 3a relative to the sleeping frame 4 to lock the first opening 3a relative to the sleeping frame 4 in the locked ajar position and to unlock the first opening 3a relative to the sleeping frame 4 of the locked ajar position.

In this way, reaching the half-open position locked by the motorized drive device 5 is implemented in a repeatable manner, while guaranteeing a frank stop of the first opening 3a relative to the sleeping frame 4 via the first locking device 20.

The first locking device 20 thus makes it possible to prohibit, or at least delay, an attempt to intrude an individual.

Advantageously, the release device 29 is configured to be activated by means of the drive arm 18 and, more particularly, of the shuttle 45, in particular a ramp 40 of the shuttle 45, during a movement of the first opening 3a relative to to the frame 4 from the closed position and, more particularly, the locked closed position to an open position of the first leaf 3a relative to the frame 4.

Thus, the activation of the release device 29, in particular by the shuttle 45, during a movement of the first opening 3a relative to the sleeping frame 4 from the closed position to an open position of the first opening 3a relative to the frame 4, frees the drive arm 18 relative to the movable arm 23 of the first locking device 20.

In this way, the drive arm 18 is unlocked relative to the movable arm 23 of the first locking device 20 and the first leaf 3a can be moved relative to the sleeping frame 4 beyond the locked ajar position, in the direction movement of the first opening 3a relative to the fixed frame 4 from the closed position to an open position.

Advantageously, the movable arm 23 comprises a stop 31. This stop 31 of the movable arm 23 is configured to limit the stroke of the drive arm 18, following the crossing of this stop 31 corresponding to a maximum locked ajar position, during a displacement of the first opening 3a relative to the sleeping frame 4 from an open position to the closed position.

Thus, the stop 31 of the movable arm 23 ensures that the first opening 3a is held in position relative to the fixed frame 4 in the locked ajar position.

In this way, the stop 31 of the movable arm 23 makes it possible to block the drive arm 18 and therefore to guarantee locking in the locked ajar position, where the bearing of the drive arm 18 against the stop 31 of the movable arm 23 corresponds to the maximum opening of the first opening 3a relative to the sleeping frame 4.

Preferably, the drive arm 18, in particular a wall 18a of the drive arm 18, is configured to cooperate with a free end 23a of the movable arm 23, during a movement of the first opening 3a relative to the sleeping frame 4 , in the direction of movement from an open position to the closed position of the first opening 3a relative to the fixed frame 4.

Thus, the drive arm 18 makes it possible to guarantee that the free end 23a of the movable arm 23 is kept in contact with the first leaf 3a in relation to the fixed frame 4 in the direction of movement from d an open position towards the closed position of the first opening 3a relative to the sleeping frame 4.

Here, the free end 23a of the movable arm 23 is the part of the movable arm 23 comprising the stop 31.

Preferably, the movable arm 23 comprises a ramp 39 configured to cooperate with the drive arm 18 and, more particularly, with the wall 18a of the drive arm 18, in other words with the casing 38 of the drive arm 18.

Advantageously, the release device 29 comprises a cam 32 movable around a second axis of rotation Y2. Furthermore, the cam 32 is configured to be moved relative to the movable arm 23.

In this exemplary embodiment, the cam 32 is assembled on the movable arm 23.

Here, the movable arm 23 comprises an opening, not shown, inside which is arranged a rotation shaft 33, so as to allow a rotary movement of the cam 32 around the second rotation Y2.

Thus, the cam 32 is rotatably mounted relative to the movable arm 23 by means of a pivot connection.

Advantageously, the first locking device 20 comprises a second elastic return element 34 disposed between the movable arm 23 and the cam 32.

Thus, the second elastic return element 34 ensures that the cam 32 is kept in a rest position relative to the movable arm 23.

Here, the second elastic return element 34 is a spring, in particular of the pin type.

The type of elastic return element between the movable arm and the cam is not limiting and may be different. It can be, in particular, a torsion spring, for example with spirals.

Advantageously, the second elastic return element 34 is located on the same axis of rotation Y2 as that of the cam 32.

In such a case, the cam 32 is in abutment against a support stop, not shown, of the movable arm 23.

Preferably, the ramp 40 of the shuttle 45 is configured to cooperate with the cam 32, during a movement of the first opening 3a relative to the sleeping frame 4, both in the direction of movement from an open position towards the closed position of the first leaf 3a relative to the sleeping frame 4 only in the direction of movement from the closed position to an open position of the first leaf 3a relative to the sleeping frame 4.

Thus, the ramp 40 of the shuttle 45 makes it possible to guarantee that the release device 29 remains in contact with the cam 32, when the first opening 3a moves relative to the sleeping frame 4, whatever the direction of movement of the first opening 3a relative to the sleeping frame 4.

Here, the ramp 40 is integrated into the shuttle 45.

In addition, the ramp 40 of the shuttle 45 makes it possible to avoid bringing the drive arm 18 into contact with the movable arm 23 of the first unlocking device 20, when the first locking device 20 is unlocked.

Following the locking of the first opening 3a with respect to the sleeping frame 4 in the closed position by means of the second locking device 21, then during movement of the first opening 3a with respect to the sleeping frame 4 according to the direction of movement from the closed position towards an open position of the first opening 3a relative to the sleeping frame 4, the shuttle 45, in particular the ramp 40 of the shuttle 45, is brought into contact with the cam 32.

Thus, the movement of the shuttle 45 by means of the motorized drive device 5 makes it possible to push back the mobile arm 23, against the force exerted by the second elastic return element 34, so as to release the stop 31 from the movable arm 23 relative to the drive arm 18.

In this way, the first locking device 20 is unlocked and the first opening 3a can be moved relative to the fixed frame 4 to an open position located beyond the locked ajar position, by means of the motorized driving device 5.

We will now describe, with reference to FIGS. 5 to 12, a method of controlling the operation of the motorized drive device 5 of the sliding window 2 for a building according to the invention.

Advantageously, the method of controlling the operation of the motorized drive device 5 comprises 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.

Advantageously, 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 shuttle 45 is positioned at- beyond the first locking device 20 in the sliding direction D of the first opening 3a relative to the frame 4.

When the shuttle 45 is positioned beyond the first locking device 20 in the sliding direction D of the first opening 3a relative to the fixed frame 4, the drive arm 18, in particular the drive element 30 of the device control 22, is also positioned beyond the first locking device 20 in the sliding direction D of the first leaf 3a relative to the 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 FIGS. 5 to 7.

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 drive arm 18 is disposed inside a recess 37 of the first locking device 20, as illustrated in FIG. 5.

Advantageously, the recess 37 of the first locking device 20 is defined at a first end by the stop 31 of the movable arm 23 and at a second end by the assembly element 25 and, more particularly, by a stop 41 of the 'assembly element 25. The first end of the recess 37 is opposite the second end thereof.

During the movement of the first opening 3a relative to the sleeping frame 4 from the closed position to the open position, the shuttle 45, in particular the ramp 40 of the shuttle 45, is moved by means of the flexible element 9 and rests on cam 32.

During this movement of the first opening 3a relative to the fixed frame 4 from the closed position to the open position, the cam 32 is held in position by means of the abovementioned abutment stop, between the cam 32 and the movable arm 23.

Thus, the cam 32 is stationary, around the axis of rotation Y2 during this movement of the first opening 3a relative to the fixed frame 4 from the closed position to the open position.

In this way, the movable arm 23 is moved relative to the assembly element 25 and, more particularly, relative to the cross member 47 by a rotational movement R1 around the first axis of rotation Y1, as illustrated in Figures 6 and 7.

Here, the rotational movement R1 of the movable arm 23 relative to the assembly element 25 is implemented against the force of the first elastic return element disposed at the first axis of rotation Y1.

When the shuttle 45 is positioned beyond the first locking device 20 in the sliding direction D of the first opening 3a relative to the frame 4, the movable arm 23 is moved to its rest position relative to the element d assembly 25 and, more particularly, with respect to the cross member 47 by a rotational movement R3 around the first axis of rotation Y1, as illustrated in FIG. 8.

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

Here, the locked ajar position of the first opening 3a relative to the sleeping frame 4 corresponds to the position where the drive arm 18 is positioned inside the recess 37 of the first locking device 20.

In addition, a so-called maximum locked ajar position of the first opening 3a with respect to the sleeping frame 4 corresponds to the bearing of the drive arm 18 against the stop 31 of the movable arm 23, as illustrated in FIG. 10.

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 FIGS. 9 to 10.

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.

Thus, the bearing of the drive arm 18 against the stop 31 of the movable arm 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.

During the movement of the first opening 3a relative to the sleeping frame 4 from the open position to the locked ajar position of the first opening 3a relative to the sleeping frame 4, the shuttle 45 is moved by means of the flexible element 9.

During this movement of the first opening 3a relative to the sleeping frame 4 from the open position to the locked ajar position of the first opening 3a relative to the sleeping frame 4, the movable arm 23, in particular the free end 23a of the movable arm 23, is moved relative to the connecting element 25 and, more particularly, relative to the cross member 47, in other words relative to a fixed part of the window 2, firstly, by a first rotational movement R1 around the first axis of rotation Y1, as illustrated in FIG. 9, and, in a second step, by a second rotational movement R3 around the first axis of rotation Y1, as illustrated in FIG. 10. The first rotational movement R1 around the first axis of rotation Y1 of the movable arm 23 is opposite to the second rotational movement R3 around the first axis of rotation Y1 of the movable arm 23.

Here, the first rotational movement R1 of the movable arm 23 relative to the assembly element 25 is implemented against the force of the first elastic return element disposed at the first axis of rotation Y1. In addition, the second rotational movement R3 around the first axis of rotation Y1 of the movable arm 23 relative to the assembly element 25 is implemented by the force exerted by the first elastic return element disposed at the level of the first axis of rotation Y1.

Thus, when the drive arm 18 is positioned inside the recess 37 of the first locking device 20, the movable arm 23 is moved into its rest position relative to the assembly element 25 and, more particularly, with respect to the crosspiece 47 by the second rotational movement R3 around the first axis of rotation Y1, as illustrated in FIG. 10.

In addition, during this movement of the first opening 3a relative to the sleeping frame 4 from the open position to the locked ajar position of the first opening 3a relative to the sleeping frame 4, the cam 32 is moved relative to the arm mobile 23 by a rotational movement R2 around the second axis of rotation Y2, as illustrated in FIG. 9.

Thus, the cam 32 is movable in rotation about the axis of rotation Y2 during this movement of the first opening 3a relative to the fixed frame 4 from the open position to the locked ajar position of the first opening 3a by relative to the frame 4.

Here, the rotational movement R2 of the cam 32 relative to the movable arm 23 is implemented against the force of the second elastic return element 34 disposed at the second axis of rotation Y2.

When the first opening 3a is in the locked ajar position relative to the sleeping frame 4, the drive arm 18 is locked in translation by the stop 31 of the movable arm 23, during a movement of the first opening 3a relative to the frame frame 4 operated from the maximum locked ajar position to an open position.

In an exemplary embodiment, the second displacement step may comprise a first substep of displacement of the first leaf 3a relative to the fixed frame 4 from the open position to a position where the drive arm 18 is located inside the recess 37 of the first locking device 20, then a second sub-step of moving the first opening 3a relative to the fixed frame 4 from the position where the drive arm 18 is located at the inside the recess 37 of the first locking device 20 up to the maximum locked ajar position of the first opening 3a relative to the sleeping frame 4.

In this exemplary embodiment, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the first additional movement step, corresponds to that of the arrow F2. In addition, the direction of movement of the first opening 3a relative to the sleeping frame 4, during the second additional movement step, corresponds to that of the arrow F1.

As a variant, the second displacement step comprises only the displacement of the first opening 3a relative to the sleeping frame 4 from the open position to the locked ajar position of the first opening 3a relative to the sleeping frame 4.

Following the second displacement step, the method comprises a step of stopping the first opening 3a relative to the sleeping frame 4 in the locked ajar position of the first opening 3a relative to the sleeping frame 4, as illustrated in FIG. 10 or Figure 11.

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.

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 first 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 third step of moving the first opening 3a relative to the sleeping frame 4 from the locked ajar position to the locked locked position.

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 F2 in FIGS. 11 and 12.

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 locked open position to the locked closed position, the drive arm 18 is driven in displacement by means of the shuttle 45 and the element flexible 9.

Thus, the deactivation of the first locking device 20 is implemented when the shuttle 45 is positioned inside the recess 37 of the first locking device 20 and, more particularly, when the cam 32 is moved to its rest position relative to the movable arm 23 by a rotational movement R4 around the second axis of rotation Y2, as illustrated in FIG. 5.

In this way, the deactivation of the first locking device 20 is implemented only when the shuttle 45 is in the position corresponding to the closed locked position of the first leaf 3a relative to the sleeping frame 4.

Such positioning of the shuttle 45 relative to the first locking device 20 makes it possible to release the cam 32 relative to the ramp 40 of the shuttle 45 and to return the cam 32 to its rest position. Thus, the release device 29 is activated, following the locking of the first opening 3a in the closed position, by means of the second locking device 21.

Here, the movement of the cam 32 in its rest position relative to the movable arm 23 by the rotational movement R4 around the second axis of rotation Y2 is configured to be implemented only when the shuttle 45 is in the position corresponding to the closed locked position of the first opening 3a relative to the sleeping frame 4.

Advantageously, as long as the cam 32 is held in an inclined position by the shuttle 45, in particular by the ramp 40 of the shuttle 45, that is to say in a position different from the rest position of the cam 32, the first locking device 20 is configured to maintain the first opening 3a in a partially open locked position relative to the sleeping frame 4, that is to say that the first locking device 20 is configured to prevent manual opening of the first opening 3a relative to the sleeping frame 4, in other words the drive arm 18 is retained inside the recess 37 of the first locking device 20 by the stop 31 of the movable arm 23.

In addition, when reaching the closed position of the first opening 3a relative to the sleeping frame 4 by means of the motorized drive device 5, the control device 22 housed in the drive arm 18 activates the second device locking 21, in particular by tilting the driving element 30 inside the driving arm 18, so as to unlock the second locking device 21.

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

Following the unlocking of the second locking device 21, the first opening 3a returns to the initial position relative to the fixed frame 4, as well as the movable arm 23 relative to the connecting element 25 and, more particularly, to the cross member 47 , as well as the cam 32 relative to the movable arm 23, as before the first movement step.

Advantageously, when the first opening 3a is in the closed locked position relative to the sleeping frame 4, the cam 32 is in its rest position, in other words the cam 32 is no longer in contact with the shuttle 45, in particular the ramp 40 of shuttle 45.

During a new execution of the first control step and the first movement step, the operation of the first locking device 20 and of the motorized drive device 5 described above is implemented in an identical manner.

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 fourth step of displacement of the first opening 3a relative to the sleeping frame 4 from the locked open position to the locked 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, corresponds to that of the arrow F2.

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.

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

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 place the first opening 3a relative to the frame standing 4 in the closed position, itself locked by the second locking device 21.

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 fourth 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 concealment device, for example of each shutter

Thanks to the present invention, the first locking device makes it possible to lock the opening relative to the sleeping frame in the partially open position locked by means of the motorized driving device.

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

In addition, the unlocking of the opening relative to the sleeping frame in connection with the first locking device is implemented by means of the motorized drive device configured to generate a displacement of the opening relative to the sleeping frame passing through the closed and locked position of the opening relative to the frame by means of the second locking device.

In this way, the unlocking of the opening relative to the sleeping frame is implemented only by means of the motorized drive device.

Furthermore, the electronic control unit of the motorized drive device makes it possible to control the movement of the opening element with respect to the sleeping frame to lock the opening element with respect to the sleeping frame in the locked open position and to unlock the opening element relative to the sleeping frame of the locked open position.

The first locking device thus makes it possible to prohibit, or at least delay, an attempt to intrude an individual.

Many modifications can be made to the embodiments described above without departing from the scope of the invention.

In particular, the motorized drive device 5 can be configured to move by sliding several openings 3a, 3b by means of the flexible element 9, in the same direction of movement or in an opposite direction of movement.

Alternatively, the electric motor 7 of the electromechanical actuator 6 can be of the asynchronous or direct current type.

In addition, the embodiments and variants envisaged can be combined to generate new embodiments of the invention, without departing from the scope of the invention.
