Description

The present invention relates to a tilt-and-turn window for a building, this window comprising a motorized drive device for moving a sash relative to a fixed frame following a tilting movement around an axis of rotation.

The invention also relates to a home automation system comprising such a tilt-and-turn window.

The present invention finally relates to a control method in operation of a motorized drive device for such a tilt-and-turn window for a building.

In general, the present invention relates to the field of windows comprising a motorized drive device setting in motion a sash relative to a fixed frame following a tilting movement around an axis of rotation, between at least a first position and at least a second position.

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

We already know the document EP 3 032 021 A1 which describes a tilt-and-turn window comprising a sash, a fixed frame, a fitting system provided between the fixed frame and the sash, and a motorized drive device configured to move the sash relative to the frame by tilting sleeping. The fitting system is of the turn-tilt type, so as to be able to pivot the sash relative to the fixed frame around a first axis of rotation and to be able to tilt the sash relative to the fixed frame around a second axis rotation. The fitting system includes locking elements. The locking elements of the fitting system are configured to assume a locked state, so as to hold the sash relative to the fixed frame in a locked closed position, a first unlocked state, so as to allow the sash to pivot relative to the fixed frame around the first axis of rotation, and a second unlocked state, so as to allow the tilting of the leaf relative to the fixed frame around the second axis of rotation. The motor drive device includes an electromechanical actuator. The electromechanical actuator includes an electric motor and an output shaft. The electromechanical actuator is arranged on a fixed part with respect to the window.

However, this window has the drawback of tilting the sash relative to the fixed frame around the second axis of rotation by means of an opening device driven by the electromechanical actuator. The opening device is made in the form of a compass comprising a main arm and a secondary arm.

In addition, the main arm of the opening device comprises a locking mechanism configured to cooperate with a mobile pin of the fitting system.

A change between two states of the locking elements of the fitting system is implemented either manually, by maneuvering a handle connected to the fitting system, or electrically, by the motorized drive device.

In the case where a change between two states of the locking elements of the fitting system is implemented electrically, the handle is moved via the fitting system, as well as the mobile pin of the fitting system configured to cooperate with the locking mechanism associated with the main arm of the opener.

Consequently, this motorized drive device is complex to implement.

In addition, the cost of obtaining the window is high due to the number and complexity of the parts making up the motorized drive device.

We also know the document US 2007/068082 A1 which describes a tilt and turn window for a building. The window comprises a sash, a fixed frame, a fitting system provided between the fixed frame and the sash, and a motorized drive device for moving the sash relative to the fixed frame by tilting. The fitting system is of the turn-tilt type, so as to be able to pivot the sash relative to the fixed frame around a first axis of rotation and to be able to tilt the sash relative to the fixed frame around a second axis rotation. The fitting system includes locking elements. The locking elements of the fitting system are configured to assume a locked state, so as to hold the sash relative to the fixed frame in a locked closed position, a first unlocked state, so as to allow the sash to pivot relative to the fixed frame around the first axis of rotation, and a second unlocked state, so as to allow the tilting of the leaf relative to the fixed frame around the second axis of rotation. The motor drive device includes an electromechanical actuator and a flexible member. The electromechanical actuator includes an electric motor. The flexible element is configured to be driven in displacement by the electromechanical actuator. The flexible element is connected to a movable element of the fitting system. The electromechanical actuator is attached to a deployment device, which serves to connect the sash to the fixed frame in the tilted position of the sash relative to the fixed frame. The window also comprises an electromechanical drive mechanism corresponding to a locking mechanism, which can be arranged on the fixed frame or on the leaf. This locking mechanism includes an electric motor and a reducer. This locking mechanism also includes an unlocking spring. When activating the locking mechanism, the sash is held against the fixed frame. This locking mechanism is part of the fitting system and is in addition to the motorized drive device arranged on the deployment device.

The object of the present invention is to solve the aforementioned drawbacks and to propose a tilt-and-turn window for a building comprising a motorized drive device for moving a sash relative to a fixed frame following a tilting movement around an axis of rotation, a home automation installation comprising such a tilt-and-turn window, as well as a method for controlling in operation a motorized drive device for such a tilt-and-turn window for a building, making it possible to move the sash by tilting relative to the fixed frame automatically via a window fitting system, while minimizing the costs of obtaining the window.

According to the invention, the motorized drive device also comprises at least one flexible element, the flexible element being configured to be driven in displacement by the electromechanical actuator. The flexible element is connected to a movable element of the fitting system. Furthermore, following the displacement of the movable element of the fitting system into a position corresponding to one of the states of the locking elements of the fitting system by means of the motorized drive device, the electromechanical actuator is configured to be electrically actuated, so as to drive the output shaft of the electromechanical actuator to a neutral position, in which at least one strand of the flexible element is relaxed.

We first describe, with reference to figures 1 to 6 , a home automation system according to the invention and installed in a building comprising an opening 1, in which is arranged a tilt-and-turn window 2, according to a first embodiment of the invention.

The window 2 comprises at least one opening 3 and a fixed frame 4.

Here, and as illustrated in figures 1 to 4 , window 2 comprises a single sash 3.

The number of openings of the window is not limiting and may be different, in particular equal to two. In such a case, the two opening elements cooperate together, in particular when these are brought into a closed position with respect to the fixed frame.

The sash 3 comprises a frame 30. The sash 3 can also comprise at least one pane 20 arranged in the frame 30 of the sash 3.

The number of panes of the opening is not limiting and can be different, in particular equal to two or more.

The window 2 also includes a fitting system 31 arranged between the fixed frame 4 and the opening 3.

The fitting system of a window is well known to those skilled in the art and does not need to be described in more detail here. The fitting system 31 of the window 2 is only partially represented on the figures 1 to 4 , so as to make them easier to read.

Window 2 also includes a handle 19 for maneuvering sash 3 relative to fixed frame 4. Handle 19 is connected to fitting system 31.

The fixed frame 4 comprises an upper crosspiece 4a, a lower crosspiece 4b and two side uprights 4c, in the assembled configuration of the window 2 with respect to the building, as illustrated in figures 1 to 4 .

The upper crosspiece 4a, the lower crosspiece 4b and the two side uprights 4c of the fixed frame 4 respectively have an inner face and at least one outer face.

The inner face of the upper crosspiece 4a, of the lower crosspiece 4b and of the two side uprights 4c of the fixed frame 4 is oriented towards the inside of the window 2 and, in particular, towards an outer edge of the frame 30, when the sash 3 is in a closed position relative to fixed frame 4.

The outer face of the upper crosspiece 4a, of the lower crosspiece 4b and of the two side uprights 4c of the fixed frame 4 is oriented towards the outside of the window 2.

The fitting system 31 of the tilt-and-turn window 2 is of the turn-tilt type, so as to be able to pivot the sash 3 relative to the fixed frame 4 around a first axis of rotation X, in the vertical example, in the assembled configuration of the window 2 relative to the building, as illustrated in figure 2 and 3 , and to be able to tilt the sash 3 relative to the fixed frame 4 around a second axis of rotation Y, in the horizontal example, in the assembled configuration of the window 2 relative to the building, as illustrated in figure 1 and 3 .

The first axis of rotation X which serves to pivot the sash 3 with respect to the fixed frame 4 is arranged on one side of the window 2, in the assembled configuration of the window 2 in the building.

The second axis of rotation Y which serves to tilt the opening 3 with respect to the fixed frame 4 is arranged in the lower part of the window 2, in the assembled configuration of the window 2 in the building.

The window 2 comprises hinge elements 17a, 17b allowing the movement of the sash 3 relative to the fixed frame 4. The hinge elements 17a, 17b are aligned along the first axis of rotation X of the sash 3 relative to the fixed frame 4.

The hinge elements 17a, 17b are arranged on the same side of the window 2.

In practice, the side of the window 2 having the hinge elements 17a, 17b is located opposite the side of the window 2 having the handle 19 for operating the fitting system 31.

The hinge elements 17a, 17b of the window 2 comprise a first rotating-tilting bearing 17a, in the lower example, in the assembled configuration of the window 2 with respect to the building, and a second rotating bearing 17b, in the example upper, in the assembled configuration of window 2 with respect to the building.

The pivoting of the sash 3 relative to the fixed frame 4 is implemented by means of the first rotating-tilting bearing 17a and the second rotating bearing 17b of the window 2.

The tilting of the opening 3 relative to the fixed frame 4 is implemented by means of the first rotating-tilting bearing 17a of the window 2.

Preferably, the fitting system 31 of the window 2 comprises an opening device 11 arranged between the opening 3 and the fixed frame 4.

Thus, the opening device 11 extends between the sash 3 and the fixed frame 4, so as to limit the tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y and to support the weight of the sash 3 in an opening position by partial or maximum tilting of the sash 3 with respect to the fixed frame 4 around the second axis of rotation Y.

Here, the opening device 11 corresponds to a compass.

In the embodiment shown in figure 1 and 4 , the compass comprises a main arm 11a and a secondary arm 11b. A first end of the main arm 11a is connected to the fixed frame 4, by means of a pivot connection, not shown. A second end of the main arm 11a is connected to the opening 3, in particular by means of a housing, not shown, provided in the opening 3. A first end of the secondary arm 11b is connected to the main arm 11a, by means of a joint, in particular located between the first and second ends of the main arm 11a. A second end of the secondary arm 11b is connected to the opening 3, by means of a pivot connection, in particular at the level of the housing provided in the opening 3.

In practice, the leaf 3 is held in a position of maximum opening by tilting relative to the fixed frame 4 by means of the opening device 11, in particular the compass.

An opening position by tilting, partial or maximum, of the leaf 3 with respect to the fixed frame 4 corresponds to a ventilation position of the building.

The fitting system 31 includes locking elements.

Thus, the locking elements of the fitting system 31 make it possible to maintain the leaf 3 with respect to the fixed frame 4 in a locked closed position.

In this way, the locking of the sash 3 with respect to the fixed frame 4 is achieved by means of the locking elements integrated in the fitting system 31 provided between the fixed frame 4 and the sash 3.

The locking elements of the fitting system 31 are configured to assume at least one locked state, so as to hold the leaf 3 relative to the fixed frame 4 in a locked closed position, a first unlocked state, so as to allow the pivoting of the sash 3 relative to the fixed frame 4 around the first axis of rotation X, and a second unlocked state, so as to allow the tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y .

Preferably, a change between two states of the locking elements of the fitting system 31 is implemented via the handle 19 of the window 2 connected to the fitting system 31.

Thus, the locking elements of the fitting system 31 are configured to be moved, so as to allow passage from a locked closed position of the sash 3 relative to the fixed frame 4 to a first unlocked closed position of the sash 3 relative to the fixed frame 4, for movement by pivoting, or to a second unlocked closed position of the sash 3 relative to the fixed frame 4, for movement by tilting.

Here, the locked state of the locking elements of the fitting system 31 corresponds to a low position of the handle 19, as illustrated in picture 3 . The first unlocked state of the locking elements of the fitting system 31, for the pivoting of the leaf 3 with respect to the fixed frame 4, corresponds to a middle position of the handle 19, as illustrated in picture 2 . The second unlocked state of the locking elements of the fitting system 31, for the tilting of the leaf 3 relative to the fixed frame 4, corresponds to a high position of the handle 19, as illustrated in figure 1 .

Window 2 also includes a motorized drive device 5. Motorized drive device 5 is configured to move sash 3 by tilting relative to fixed frame 4.

The motorized drive device 5 is also configured to drive the handle 19 via the fitting system 31.

The change between two states of the locking elements of the fitting system 31, either the locked state, the first unlocked state or the second unlocked state, is implemented either manually by a user of the window 2 or automatically by the device. motor drive 5.

Here, the handle 19 is set in motion by means of the motorized drive device 5, during a change between two states of the locking elements of the fitting system 31.

The motorized drive device 5 makes it possible to move the sash 3 automatically by tilting relative to the fixed frame 4, in particular between the position of maximum opening by tilting the sash 3 relative to the fixed frame 4 and the position of closing of the sash 3 relative to the fixed frame 4.

The motor drive device 5 includes an electromechanical actuator 6. The electromechanical actuator 6 includes an electric motor 7 and an output shaft 8.

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

The electromechanical actuator 6 may also include a gear reduction device, not shown.

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

Advantageously, the electric motor 7 and, possibly, the gear reduction device are arranged inside a casing 16 of the electromechanical actuator 6.

The motorized drive device 5 also comprises at least one flexible element 9. The flexible element 9 is configured to be driven in displacement by the electromechanical actuator 6.

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

Thus, the use of the flexible element 9 to move the sash 3 relative to the fixed 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. motorized drive 5, in particular with respect to a belt or chain.

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.

The flexible element 9 can be made of a synthetic material, such as for example nylon or polyethylene of very high molar mass.

Thus, the use of the 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 can be different. In particular, it may be a steel.

Means for controlling the electromechanical actuator 6 allow movement by tilting of the leaf 3 relative to the fixed frame 4. These control means comprise at least one 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, to allow the supply of electric power 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 tilting the sash 3 relative to the fixed frame 4.

In this way, the window 2 includes the electronic control unit 10. More specifically, the electronic control unit 10 is integrated into the motorized drive device 5.

The motor 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 by wired or wireless link 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 an order reception module, not shown, in particular radio orders transmitted 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. that 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 comprises selection elements and, possibly, 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 Anglo-Saxon term "Liquid Crystal Display") or TFT (acronym of the Anglo-Saxon term "Thin Film Transistor"). The selection and display elements can also be produced by means of a touch screen.

The local control unit 12 can be a fixed or nomadic control point. A fixed control point corresponds to a control box intended to be fixed on a facade of a wall of the building, or even on a face of the fixed frame 4 of the window 2. A mobile control point corresponds to a remote control intended to be handled by a user.

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 closing control commands by tilting and, possibly, opening by tilting of the opening 3 with respect to to the fixed 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 put the electromechanical actuator 6 of the motorized drive device 5 into operation and, in particular, allow the supply of electrical energy to the electromechanical actuator 6.

In practice, the electric power supply of the electromechanical actuator 6 is controlled by a command order received by the electronic control unit 10 coming from the local control unit 12, from the central control unit 13 or of a sensor.

For clarity of the drawing, the control units 12, 13 and the server 14 are shown only at the figure 1 .

Here, and as shown in picture 3 , the electronic control unit 10 is arranged inside the casing 16 of the electromechanical actuator 6.

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

By way of non-limiting example, the hardware means may 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 according to data from the sensor measuring the environment parameter 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 the humidity, the temperature, the rate of carbon dioxide or the rate of a volatile organic compound in the air.

Preferably, the activation of the local control unit 12 by the user takes priority over the activation of the central control unit 13, so as to control the closing and, possibly, the opening by tilting of the sash 3 in relation to the fixed frame 4.

Thus, the activation of the local control unit 12 directly drives the electronic control unit 10 associated with the motorized drive device 5 according to a selection made by the user, possibly inhibiting a control command that can be emitted 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 command corresponding to a press on a selection element of the local control unit 12, such as a remote control or a fixed command point.

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

Advantageously, the motorized drive device 5 makes it possible to move the sash 3 automatically by tilting with respect to the fixed frame 4 to a predetermined position, between the closed position and the maximum open position. The movement by tilting of the sash 3 relative to the fixed frame 4 to the predetermined position, in particular of partial opening or closing, is put into work following receipt of a control command issued by the local control unit 12, 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 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.

As a variant, the motorized drive device 5, in particular the electromechanical actuator 6, is supplied with electrical energy from an electrical power supply network. In such a case, the electromechanical actuator 6 comprises an electric power cable allowing it to be supplied with electric power from the mains power supply network.

Here, the electromechanical actuator 6 is fixed in a box 23 by means of fixing elements, not shown. The box 23 is arranged above the window 2, in the assembled configuration of the window 2 with respect to the building.

In the exemplary embodiment illustrated in figures 1 to 4 , the electromechanical actuator 6 is held at the level of the side walls of the box 23, via a tube 47.

Alternatively, not shown, the electromechanical actuator 6 is fixed on the upper crosspiece 4a of the fixed frame 4, in particular on the outer face of the upper crosspiece 4a, by means of fixing elements, not shown.

Thus, the motorized drive device 5 is configured to be implemented on a tilt-and-turn window 2 comprising a fixed frame 4 provided with an upper crosspiece compatible with the fixing elements and a lower crosspiece 4b and uprights standard 4c side panels.

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

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

In practice, the fixing elements of the electromechanical actuator 6 on the upper crosspiece 4a of the fixed frame 4 comprise two supports. A first support is assembled at a first end of the electromechanical actuator 6. A second support is assembled at a second end of the electromechanical actuator 6. The first end of the electromechanical actuator 6 is opposite the second end of the electromechanical actuator 6.

Advantageously, the window 2 comprises an access hatch 24 to the motorized drive device 5 and, more particularly, to the electromechanical actuator 6, as illustrated only in figure 4 .

Thus, the access hatch 24 makes it possible to carry out a maintenance operation of the motorized drive device 5 and/or a repair operation thereof.

Here and as shown in figure 4 , the access hatch 24 extends along the entire length L of the upper crosspiece 4a of the fixed frame 4.

Alternatively, not shown, the access hatch 24 extends only along part of the length L of the upper crosspiece 4a of the fixed frame 4.

Here and as shown in figure 4 , the access hatch 24 is provided in the trunk 23.

Alternatively, not shown, the access hatch 24 is formed in the upper crosspiece 4a of the fixed frame 4.

The flexible element 9 is connected to a movable element 27 of the fitting system 31.

Thus, the motorized drive device 5 makes it possible to automatically tilt the sash 3 with respect to the fixed frame 4 around the second axis of rotation Y, from an opening position by tilting to a closing position by the sash 3 with respect to the fixed frame 4, by driving the flexible element 9 by the electromechanical actuator 6.

Furthermore, when moving the movable element 27 of the fitting system 31 by means of the motorized drive device 5 and, in particular, by electrically actuating the electromechanical actuator 6, the flexible element 9 is driven in displacement, then the locking elements of the fitting system 31 are driven in displacement, as well as the handle 19.

In practice, the movable element 27 of the fitting system 31 is mounted on the opening 3.

The position of the movable element 27 of the fitting system 31 is associated with the position of the handle 19 for maneuvering the opening 3 with respect to the fixed frame 4.

Thus, the movable element 27 of the fitting system 31 and the handle 19 are mechanically linked via the fitting system 31.

In practice, the movable element 27 of the fitting system 31 is a movable pin inside a groove 29 of the fitting system 31.

Preferably, the movable element 27 of the fitting system 31 is separate from the locking elements of the fitting system 31.

Alternatively, not shown, the movable element 27 of the fitting system 31 is one of the locking elements of the fitting system 31. In such a case, the movable element 27 is made by means of a pin configured to cooperate with a cavity made in the fixed frame 4.

Following the displacement of the movable element 27 of the fitting system 31 into a position corresponding to one of the states of the locking elements of the fitting system 31 by means of the motorized drive device 5, the electromechanical actuator 6 is configured to be electrically actuated, so as to drive the output shaft 8 of the electromechanical actuator 6 to a neutral position, in which at least one strand of the flexible element 9 is relaxed.

Thus, the motorized drive device 5 of the window 2 makes it possible to move the sash 3 by tilting relative to the fixed frame 4 automatically via the fitting system 31.

In addition, the drive of the output shaft 8 of the electromechanical actuator 6 to the neutral position, following the positioning of the movable element 27 of the fitting system 31 in a position corresponding to one of the states of the elements locking of the fitting system 31 by means of the motorized drive device 5, so that at least one strand of the flexible element 9 is relaxed, makes it possible to manually manipulate the sash 3 with respect to the fixed frame 4, or by a tilting movement around the second axis of rotation Y, or by a pivoting movement around the first axis of rotation X, without constraint linked to the electromechanical actuator 6.

In this way, a manual movement, in particular by the user, of the sash 3 with respect to the fixed frame 4 can be implemented, since the output shaft 8 of the electromechanical actuator 6 is returned to the position neutral, after each displacement, by means of the motorized drive device 5, of the movable element 27 of the fitting system 31 into a position corresponding to one of the states of the locking elements of the fitting system 31.

The return to the neutral position of the output shaft 8 of the electromechanical actuator 6, so that at least one strand of the flexible element 9 is relaxed, after each movement, by means of the motorized drive device 5, of the movable element 27 of the fitting system 31 in a position corresponding to one of the states of the locking elements of the fitting system 31, makes it possible to guarantee the possibility of manually maneuvering the opening sash 3 with respect to the fixed frame 4, either by a tilting movement around the second axis of rotation Y, or by a pivoting movement around the first axis of rotation X, in particular, in the event of a power failure electricity or in the event of a malfunction or loss of the local control unit 12.

In this way, such an arrangement of the motorized drive device 5 makes it possible to dispense with a disengagement mechanism between the movable element 27 of the fitting system 31 and the electromechanical actuator 6.

Following the displacement of the movable element 27 of the fitting system 31 into a position corresponding to the second unlocked state of the locking elements of the fitting system 31, the driving of the output shaft 8 of the electromechanical actuator 6 up to in the neutral position, in which at least one strand of the flexible element 9 is relaxed, makes it possible to manually manipulate the opening 3 with respect to the fixed frame 4 following a tilting movement around the second axis of rotation Y.

Such a configuration of the electromechanical actuator 6 also makes it possible to manually manipulate the handle 19, so as to modify the position of the locking elements of the fitting system 31, in particular to manually move the sash 3 relative to the fixed frame 4, either following a movement by pivoting around the first axis of rotation X, or following a movement by tilting around the second axis of rotation Y.

This configuration of the electromechanical actuator 6 is particularly advantageous when the movable element 27 of the fitting system 31 is positioned in a position corresponding to the locked state or the second unlocked state of the locking elements of the fitting system 31.

Such a motorized drive device 5 makes it possible to manually pivot the sash 3 relative to the fixed frame 4 around the first axis of rotation X and to manually tilt the sash 3 relative to the fixed frame 4 around the second axis of rotation Y .

In this way, the motorized drive device 5 gives the user the possibility of manually opening and closing the sash 3 with respect to the fixed frame 4, by pivoting around the first axis of rotation X and by tilting around the second axis of rotation Y.

Furthermore, the arrangement of the motorized drive device 5 makes it possible to guarantee reliable operation of the window 2.

In addition, the motor drive device 5 of the window 2 is independent of the opening device 11 of the window 2.

Thus, the opening device 11 of the window 2 is devoid of equipment motor drive.

In this way, the drive force transmitted by the motorized drive device 5 and, in particular, by the flexible element 9, without acting directly on the opening device 11, is constant and limited, compared to a motorized drive device acting directly on the opening device 11.

Furthermore, the drive force transmitted by the motorized drive device 5 and, in particular, by the flexible element 9, without acting directly on the opening device 11, makes it possible to overcome a force of bracing at the level of the elements constituting the motorized drive device 5.

Advantageously, when moving the movable element 27 of the fitting system 31 into a position corresponding to one of the states of the locking elements of the fitting system 31 by means of the motorized drive device 5, the fitting 31 is configured to drive handle 19.

Advantageously, the movements by pivoting of the opening 3 relative to the fixed frame 4 around the first axis of rotation X are only implemented manually, in particular by the user.

Thus, the pivoting movements of the sash 3 relative to the fixed frame 4 around the first axis of rotation X between an opening position by pivoting of the sash 3 relative to the fixed frame 4 and the closed position of the opening 3 relative to the fixed frame 4, and vice versa, are implemented manually, in particular by the user.

The closing movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y is implemented by means of the flexible element 9, during the electrical activation of the electromechanical actuator 6, until an end-of-travel position is reached, where the end-of-travel position corresponds to the closed position of the sash 3 relative to the fixed frame 4.

The detection of the reaching of the stroke position is implemented through the end of stroke detection device and, in particular, by means of the electronic control unit 10.

Following the movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, until the closed position of the sash 3 relative to the fixed frame 4, the flexible element 9 is configured to drive the movable element 27 of the fitting system 31 from the position corresponding to the second unlocked state of the locking elements of the fitting system 31 to the position corresponding to the locked state of the locking elements of the fitting system 31, by the electrical activation of the electromechanical actuator 6.

Thus, the locking of the sash 3 relative to the fixed frame 4, in the closed position of the sash 3 relative to the fixed frame 4, is implemented by means of the flexible element 9, during electrical activation of the electromechanical actuator 6.

Following the locking of the leaf 3 relative to the fixed frame 4 in the closed position, the electromechanical actuator 6 is configured to be actuated electrically, so as to drive the output shaft 8 of the electromechanical actuator 6, in particular in a drive direction in clockwise rotation, to the neutral position, in which at least one strand of the flexible element 9 is relaxed.

Thus, as long as the output shaft 8 of the electromechanical actuator has not reached the neutral position, the flexible element 9 is kept under tension, so that the sash 3 cannot be moved relative to the frame. frame 4 manually, either following a pivoting movement around the first axis of rotation X or following a tilting movement around the second axis of rotation Y.

Prior to an opening movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, the flexible element 9 is configured to drive the movable element 27 of the fitting system 31, from from the position corresponding to the locked state of the locking elements of the fitting system 31 to the position corresponding to the second unlocked state of the locking elements of the fitting system 31, by the electrical activation of the electromechanical actuator 6, in particular according to a drive direction in counterclockwise rotation of the output shaft 8 of the electromechanical actuator 6.

Thus, the unlocking of the sash 3 relative to the fixed frame 4, in the closed position of the sash relative to the fixed frame 4, is implemented by means of the flexible element 9, during the electrical activation of the electromechanical actuator 6.

Following the unlocking of the leaf 3 with respect to the fixed frame 4 in the closed position, the electromechanical actuator 6 is configured to be actuated electrically, so as to drive the output shaft 8 of the electromechanical actuator 6, in particular in a drive direction in clockwise rotation, to the neutral position, in which at least one strand of the flexible element 9 is relaxed.

Thus, as long as the output shaft 8 of the electromechanical actuator has not reached the neutral position, the flexible element 9 is kept under tension, so that the sash 3 cannot be moved relative to the frame. frame 4 following a tilting movement around the second axis of rotation Y.

Preferably, a change between two states of the locking elements of the fitting system 31 by means of the motorized drive device 5 is only implemented when the sash 3 is in the closed position with respect to the fixed frame 4.

In practice, the window 2, in particular the fitting system 31, comprises an anti-error system, not shown, in particular a retractable pin mounted on the fixed frame 4, so as to prevent the movement of the movable element 27 of the fitting system 31, in particular inside the groove 29, when the leaf 3 is in an open position, by tilting or by pivoting, relative to the fixed frame 4.

We now describe, with reference to figures 5 and 6 , the integration of the motorized drive device 5 at the level of the tilt-and-turn window 2.

Advantageously, the flexible element 9 comprises at least one main flexible element 9. The main flexible element 9 comprises a first strand 9a and a second strand 9b.

Here, the flexible element 9 comprises only the main flexible element 9.

Following the displacement of the movable element 27 of the fitting system 31 into a position corresponding to one of the states of the locking elements of the fitting system 31 by means of the motorized drive device 5, the electromechanical actuator 6 is configured to be electrically actuated, so as to drive the output shaft 8 of the electromechanical actuator 6 to the neutral position, in which the first and second strands 9a, 9b of the main flexible element 9 are relaxed.

Advantageously, the main flexible element 9 makes it possible, on the one hand, to move the sash 3 relative to the fixed frame 4 following a tilting movement around the second axis of rotation Y and, on the other hand, to make a change between two states of the locking elements of the fitting system 31, either the locked state, the first unlocked state or the second unlocked state, by directly driving the mobile element 27 of the fitting system 31.

Here and as shown in figures 4 and 6 , the electromechanical actuator 6 is of the tubular type.

Here, the motorized drive device 5 also comprises a pulley 15 for winding the main flexible element 9. The winding pulley 15 is driven in rotation by the output shaft 8 of the electromechanical actuator 6.

Preferably, the winding pulley 15 is held in the box 23, in particular by means of a side wall of the box 23 or on the upper crosspiece 4a of the fixed frame 4, through the same fixing elements as those of the actuator electromechanical 6.

Advantageously, the motorized drive device 5 is a subassembly preassembled before assembly, in the example on the fixed frame 4, and comprising at least the electromechanical actuator 6, the winding pulley 15, the main flexible element 9 and the electronic control unit 10.

When closing the sash 3 relative to the fixed frame 4 by means of the motorized drive device 5, from an open position by tilting the sash 3 relative to the fixed frame 4, the main flexible element 9 is driven around winding pulley 15 by electromechanical actuator 6.

One end of the first strand 9a of the main flexible element 9 is connected to a first part of the winding pulley 15. One end of the second strand 9b of the main flexible element 9 is connected to a second part of the pulley d winding 15.

Advantageously, the end of each of the first and second strands 9a, 9b of the main flexible element 9 is attached respectively to the first part or to the second part of the winding pulley 15 by means of fastening elements 32.

Thus, the end of each of the first and second strands 9a, 9b of the main flexible element 9 is respectively fixed directly to the first part or to the second part of the winding pulley 15.

In practice, the fixing elements 32 of the end of each of the first and second strands 9a, 9b of the main flexible element 9 are elements of the cable clamp type.

Here, these fixing elements 32 are screws, in particular of the self-tapping type, screwing into the winding pulley 15, so as to fix the first and second strands 9a, 9b of the main flexible element 9 by wedging between the head of the screws and the winding surface of the main flexible element 9 of the winding pulley 15.

The winding pulley 15 and the output shaft 8 of the electromechanical actuator 6 have the same axis of rotation Z.

Here, the second axis of rotation Y of the sash 3 relative to the fixed frame 4 is parallel to the axis of rotation Z of the winding pulley 15 and of the output shaft 8 of the electromechanical actuator 6.

The direction of winding, respectively of unwinding, of the first strand 9a of the main flexible element 9 around the first part of the winding pulley 15 is opposite to the direction of winding, respectively of unwinding, of the second strand 9b of the main flexible element 9 around the second part of the winding pulley 15.

Thus, when moving the leaf 3 relative to the fixed frame 4 according to an opening movement by tilting, in particular when moving by tilting from the closed position to an open position by tilting the leaf 3 by relative to the fixed frame 4, the first strand 9a of the main flexible element 9 winds around the first part of the winding pulley 15, while the second strand 9b of the main flexible element 9 unwinds around the second part of the winding pulley 15.

In addition, when moving the leaf 3 relative to the fixed frame 4, by means of the motorized drive device 5, according to a closing movement by tilting, in particular when moving by tilting from an open position by tilting towards the closed position of the sash 3 with respect to the fixed frame 4, the first strand 9a of the main flexible element 9 unwinds around the first part of the winding pulley 15, while the second strand 9b of the main flexible element 9 wraps around the second part of the winding pulley 15.

The opening movement by tilting of the sash 3 relative to the fixed frame 4 is opposed to the closing movement by tilting.

In this way, the direction of drive in rotation of the first strand 9a of the main flexible element 9 around the first part of the winding pulley 15 is opposite to the direction of drive in rotation of the second strand 9b of the main flexible element 9 around the second part of the winding pulley 15.

In addition, when tilting the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, in particular up to the maximum open position by tilting the sash 3 relative to the fixed frame 4, the first and second strands 9a, 9b of the main flexible element 9 are driven at least partly around the winding pulley 15.

Thus, the tilting of the opening 3 with respect to the fixed frame 4 around the second axis of rotation Y can be implemented without discomfort related to the main flexible element 9 connected, on the one hand, to the movable element 27 of the fitting system 31 and, on the other hand, to the winding pulley 15.

In this way, the first and second strands 9a, 9b of the main flexible element 9 can be driven around the winding pulley 15, so that the sash 3 can be tilted relative to the fixed frame 4 around the second axis of rotation Y, up to the maximum opening position by tilting.

In an opening position by tilting of the sash 3 relative to the fixed frame 4, the first and second strands 9a, 9b of the main flexible element 9 are driven around the winding pulley 15 and extend between the fixed frame 4 and the opening 3.

The motorized drive device 5 also comprises at least one angle transmission pulley 21, 33.

In the exemplary embodiment illustrated in figure 1 , 2 , 5 and 6 , the motorized drive device 5 comprises a first angle transmission pulley 21 mounted on the fixed frame 4, in particular on a side upright 4c of the fixed frame 4. In addition, the motorized drive device 5 comprises a second bevel gear pulley 33 mounted on the sash 3, in particular on a side upright of the frame 30 of the sash 3.

The main flexible element 9 is configured to cooperate with the first and second bevel pulleys 21, 33, when the main flexible element 9 is driven by the electromechanical actuator 6.

Each angle transmission pulley 21, 33 can be produced, for example, by an idler pulley, in other words mounted freely in rotation, in particular mounted on one of the two side uprights of the fixed frame 4 or of the opening 3 , or by a fixed pulley, in other words fixed to its axis, in particular fixed to one of the two side uprights of the fixed frame 4 or of the opening 3.

The first and second strands 9a, 9b of the main flexible element 9 extend respectively between the winding pulley 15, the angle transmission pulleys 21, 33 and the movable element 27 of the fitting system 31.

Preferably, the first and second angle transmission pulleys 21, 33 are arranged facing each other, in the assembled configuration of the window 2 in the building and, in particular, when the sash 3 is in the closed position with respect to fixed frame 4.

Here, the main flexible element 9 is configured to transmit a vertical movement to the movable element 27 of the fitting system 31, in the assembled configuration of the window 2 in the building, in particular along the length D of the groove 29 of the hardware system 31.

Advantageously, the relaxation of the first and second strands 9a, 9b of the main flexible element 9, when the output shaft 8 of the electromechanical actuator 6 is in the neutral position, is obtained thanks to a length of the flexible element main 9 greater than the minimum length thereof to connect the winding pulley 15 with the movable element 27 of the fitting system 31 via the angle transmission pulleys 21, 33.

Advantageously, the motorized drive device 5 comprises at least one other angle transmission pulley 43 mounted on the fixed frame 4, in particular on a side upright 4c of the fixed frame 4, as illustrated in figure 2 and 5 .

This other angle transmission pulley 43 is called, in the present case, third angle transmission pulley.

The main flexible element 9 is configured to also cooperate with the third angle transmission pulley 43, when the main flexible element 9 is driven by the electromechanical actuator 6.

Preferably, the third angle transmission pulley 43 is arranged above the first angle transmission pulley 21 and, optionally, above the movable element 27 of the fitting system 31, in the assembled configuration of window 2 in the building.

Thus, the third bevel pulley 43 makes it possible to slow down the movement of the sash 3 relative to the fixed frame 4, during an opening movement by tilting of the sash 3 relative to the fixed frame 4 around of the second axis of rotation Y, in particular under the action exerted by the thrust mechanism 50.

Here, the third angle transmission pulley 43 is configured to cooperate with the second strand 9b of the main flexible element 9.

Advantageously, the motorized drive device 5 comprises an additional bevel pulley 49 mounted on the sash 3, in particular on the frame 30 of the sash 3, so as to guide the main flexible element 9, in particular the second strand 9b of the main flexible element 9.

Here, the additional corner deflection pulley 49 is arranged above the second corner deflection pulley 33 and, more particularly, above the movable element 27 of the fitting system 31, in the assembled configuration of window 2 in the building.

During a movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, by means of the motorized drive device 5, from an opening position by tilting of the sash 3 with respect to the fixed frame 4 towards the closed position of the sash 3 with respect to the fixed frame 4, the main flexible element 9 is driven by the winding pulley 15, so as to bring the sash 3 closer by relative to the fixed frame 4 before moving the movable element 27 of the fitting system 31, to implement a change of state of the locking elements of the fitting system 31 between the second unlocked state and the locked state.

Here, this tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y is implemented by pulling on one of the first and second strands 9a, 9b of the main flexible element 9 and by driving the output shaft 8 of the electromechanical actuator 6 in a predetermined direction of rotation, in particular in the counterclockwise direction of rotation.

The closing movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y is implemented by means of the main flexible element 9 and, in particular, of the first strand 9a of the element main hose 9, upon electrical activation of electromechanical actuator 6.

Following the movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, until the closed position of the sash 3 relative to the fixed frame 4, the main flexible element 9 and, in particular, the first strand 9a of the main flexible element 9, is configured to drive the movable element 27 of the fitting system 31, from the position corresponding to the second unlocked state of the locking elements of the fitting system 31 until 'to the position corresponding to the locked state of the locking elements of the fitting system 31, by the electrical activation of the electromechanical actuator 6.

Thus, the locking of the sash 3 relative to the fixed frame 4, in the closed position of the sash 3 relative to the fixed frame 4, is implemented by means of the main flexible element 9 and, in particular, of the first strand 9a of the main flexible element 9, during the electrical activation of the electromechanical actuator 6.

Following a tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y towards an opening position by tilting, the sash 3 can be moved manually into the closed position, in particular by the user, by a tilting movement of the opening 3 relative to the fixed frame 4 around the second axis of rotation Y.

In such a case, following the manual movement, by tilting, of the leaf 3 from an open position to the closed position, the motorized drive device 5 activates the electromechanical actuator 6, so as to drive the main flexible element 9 around the winding pulley 15.

Thus, following the manual movement of the opening 3 from an open position to the closed position, the drive of the main flexible element 9 around the winding pulley 15 is implemented automatically by motor drive device 5.

Furthermore, the driving of the main flexible element 9 around the winding pulley 15 can be implemented both in the unlocked closed position of the leaf 3 relative to the fixed frame 4 and in the closed position. locked of the sash 3 in relation to the fixed frame 4.

Advantageously, the activation of the electromechanical actuator 6 is triggered by means of a sensor.

The sensor can be, for example, a position detection sensor of the opening 3 relative to the fixed frame 4.

Preferably, during the pivoting of the opening 3 relative to the fixed frame 4 around the first axis of rotation X, in particular up to a position of maximum opening by pivoting of the opening 3 relative to the fixed frame 4, the The main flexible element 9 is held in position around the winding pulley 15 and the bevel pulleys 21, 33, that is to say without being moved.

Thus, the pivoting of the opening 3 with respect to the fixed frame 4 around the first axis of rotation X can be implemented manually without discomfort related to the main flexible element 9 connected, on the one hand, to the movable element 27 of the fitting system 31 and, on the other hand, to the winding pulley 15.

In addition, a pivoting movement of the sash 3 relative to the fixed frame 4 around the first axis of rotation X towards an opening position by pivoting is implemented manually by exerting traction on the sash 3, in particular using handle 19 of window 2.

Advantageously, the neutral position of the output shaft 8 of the electromechanical actuator 6 can be identical, when the locking elements of the fitting system 31 are either in the position corresponding to the locked state of the opening 3 with respect to to the fixed frame 4 or in the position corresponding to the second unlocked state of the opening 3 with respect to the fixed frame 4.

As shown in figures 1 to 4 , the electromechanical actuator 6 and the winding pulley 15 are arranged in the box 23 formed above the window 2, in particular extending above the upper crosspiece 4a of the fixed frame 4.

Thus, the electromechanical actuator 6 and the winding pulley 15 are hidden in the box 23, so as to guarantee the aesthetic appearance of the window 2.

Advantageously, the fixed frame 4 comprises at least one passage 26a, 26b extending from the outer face of the upper crosspiece 4a of the fixed frame 4 to the inner face of this upper crosspiece 4a, inside which is disposed part of the main flexible element 9.

Here and as shown in figures 4 and 6 , the fixed frame 4 comprises two passages 26a, 26b cooperating respectively with one of the first and second strands 9a, 9b of the main flexible element 9.

Thus, each of the first and second strands 9a, 9b of the main flexible element 9 can slide inside one of the passages 26a, 26b extending through the fixed frame 4, depending on the movement by tilting of the leaf 3 with respect to the fixed frame 4, while limiting the forces exerted on the electromechanical actuator 6 and the movable element 27 of the fitting system 31.

To the figure 6 , the upper crosspiece 4a is shown very schematically, in the form of a horizontal plate. In practice, this upper crosspiece 4a has a height, that is to say a vertical thickness, which is non-zero. The passages 26a, 26b extend, through the upper crosspiece 4a, over this non-zero height.

Preferably, each passage 26a, 26b extending through the fixed frame 4 is oriented in a vertical direction, in the assembled configuration of the window 2 with respect to the building.

Thus, each passage 26a, 26b is not very visible, so as to improve the aesthetics of the window 2.

In addition, such an orientation of each passage 26a, 26b makes it possible to limit the number of angle transmissions to connect the main flexible element 9, on the one hand, to the movable element 27 of the fitting system 31 and, d on the other hand, to winding pulley 15.

In such a case where each of the first and second strands 9a, 9b of the main flexible element 9 extends partly inside one of the passages 26, 26b formed in the fixed frame 4, each of the first and second strands 9a, 9b of the main flexible element 9 comprises a plug 22, so as to obstruct one end of the associated passage 26a, 26b, when the opening 3 is in a closed position with respect to the fixed frame 4.

Thus, the closing of one end of each passage 26a, 26b extending through the fixed frame 4 by the plugs 22 arranged respectively on the first and second strands 9a, 9b of the main flexible element 9 makes it possible to free from problems of tightness and thermal insulation of the window 2 in the building generated by the integration of the motorized drive device 5 on the window 2, since in such a case a modification of the fixed frame 4 is necessary to allow the passage of the first and second strands 9a, 9b of the main flexible element 9 inside the passages 26a, 26b made in the fixed frame 4.

Advantageously, the closure of one end of each passage 26a, 26b by the plugs 22 is implemented in the locked closed position of the opening 3 with respect to the fixed frame 4.

Here and as shown in figure 5 , the main flexible element 9 is attached to the movable element 27 of the fitting system 31, whatever the state of the locking elements of the fitting system 31, that is to say both in the state locked, the first unlocked state than the second unlocked state.

Thus, the main flexible element 9 is attached to the movable element 27 of the fitting system 31 permanently.

In this way, the connection between the main flexible element 9 and the movable element 27 of the fitting system 31 is simplified and makes it possible to minimize the costs of obtaining the window.

In an exemplary embodiment, the fixing of the main flexible element 9, in particular of the second strand 9b of the main flexible element 9, on the movable element 27 of the fitting system 31 is implemented by means of a node.

The attachment of the main flexible element to the movable element of the fitting system is not limiting and may be different. In particular, it may be a fixing by screwing a fixing screw through an eyelet of the main flexible element and a hole of the movable element of the fitting system.

Here and as shown in figure 1 , 2 and 5 , a part of the main flexible element 9 of the motor drive device 5 extends between the leaf 3 and the fixed frame 4 on the side of the window 2 comprising the hinge elements 17a, 17b, so as to guarantee the displacements by tilting and by pivoting of the opening 3 with respect to the fixed frame 4, as well as the aesthetic appearance of the window 2.

In addition, the motorized drive device 5 makes it possible to automatically tilt the sash 3 with respect to the fixed frame 4 around the second axis of rotation Y, from an open position by tilting to a closed position. of the sash 3 with respect to the fixed frame 4, by driving the main flexible element 9 around the winding pulley 15.

The motorized drive device 5 makes it possible to close, and possibly open, the sash 3 in a motorized manner relative to the fixed frame 4, by tilting around the second axis of rotation Y.

Furthermore, part of the main flexible element 9 of the motorized drive device 5 is arranged between the leaf 3 and the fixed frame 4 on the side of the first axis of rotation X, so as to occupy a concealed position between the frame sleeping 4 and the sash 3.

Advantageously, the window 2 comprises a mechanism 50 for pushing the sash 3 relative to the fixed frame 4 following an opening movement by tilting around the second axis of rotation Y.

The thrust mechanism 50 is configured to drive the sash 3 relative to the fixed frame 4 following an opening movement by tilting around the second axis of rotation Y, when the output shaft 8 of the electromechanical actuator 6 reaches the neutral position, as previously defined.

The opening movement by tilting of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y by means of the thrust mechanism 50 is implemented only after the neutral position has been reached by the output shaft 8 of electromechanical actuator 6.

Here and as shown in figure 2 , the thrust mechanism 50 comprises an elastic element 18.

The elastic element 18 is arranged so as to push the sash 3 in an opening direction by tilting the sash 3 relative to the fixed frame 4.

Thus, the elastic element 18 causes an opening force on the sash 3, so as to tilt the sash 3 relative to the fixed frame 4 around the second axis of rotation Y, when the sash 3 is in a position lock unlocked in relation to the fixed frame 4.

In addition, the drive of the output shaft 8 of the electromechanical actuator 6 to the neutral position, following the positioning of the movable element 27 of the fitting system 31 in a position corresponding to the second unlocked state of the locking elements of the fitting system 31 by means of the motorized drive device 5, so that the strands of the main flexible element 9 are relaxed, makes it possible to move by tilting, by means of the elastic element 18, the leaf 3 by relative to the fixed frame 4 around the second axis of rotation Y and, in particular, without user intervention and without activation of the electromechanical actuator 6.

Advantageously, the opening force caused by the elastic element 18 is greater than the force generated by one or more seals arranged between the fixed frame 4 and the opening 3 and by the weight of the opening 3, so as to tilt the sash 3 relative to the fixed frame 4 around the second axis of rotation Y.

Thus, the elastic element 18 makes it possible to initiate the tilting movement of the leaf 3 relative to the fixed frame 4 around the second axis of rotation Y, from the closed position of the leaf 3 relative to the frame. sleeping 4 to one opening position by tilting the sash 3 relative to the fixed frame 4.

Advantageously, the tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y can then be generated or maintained by the weight of the sash 3.

In practice, the elastic element 18 is a spring, for example leaf or spiral.

In the closed position of the sash 3 relative to the fixed frame 4 and, more particularly, locked, the elastic element 18 is compressed between the sash 3 and the fixed frame 4.

Thus, the elastic element 18 disposed between the sash 3 and the fixed frame 4 generates a small footprint, while guaranteeing the tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y.

Advantageously, the compression of the elastic element 18 between the opening 3 and the fixed frame 4 is implemented during the activation of the motorized drive device 5 and, more particularly, by the drive of the flexible element main 9 around winding pulley 15.

Here, a first end of the elastic element 18 is fixed on one face of the fixed frame 4 and a second end of the elastic element 18 is arranged facing one face of the frame 30 of the opening 3 , in the closed position of the sash 3 relative to the fixed frame 4.

The elastic element 18 can be arranged in the lower part or in the upper part of a rabbet 25 of the window 2, between the fixed frame 4 and the opening 3.

Preferably, the elastic element 18 is arranged on the side of the window 2 comprising the hinge elements 17a, 17b of the opening 3 with respect to the fixed frame 4.

Thus, the elastic element 18 makes it possible to move the sash 3 by tilting with respect to the fixed frame 4 around the second axis of rotation Y, when the fitting system 31 is in the second unlocked state, while limiting the force generated on the sash 3 when the fitting system 31 is in the first unlocked state, so as to avoid moving the sash 3 by pivoting with respect to the fixed frame 4 around the first axis of rotation X.

Alternatively, not shown, the thrust mechanism 50 of the opening 3 relative to the fixed frame 4 following an opening movement by tilting around the second axis of rotation Y comprises a finger configured to cooperate with a cam.

Advantageously, the finger is mounted on the fixed frame 4. The finger can rotate around an axis of rotation parallel to the second axis of rotation Y.

In a state of rest, the finger is arranged in a vertical direction, in the assembled configuration of the window 2 with respect to the building, between the fixed frame 4 and the sash 3.

The cam is configured to cooperate with the finger when the output shaft 8 of the electromechanical actuator 6 is driven in displacement, by the electrical activation of the latter, from the position of the output shaft 8 corresponding to the second unlocked state, to allow a tilting movement around the second axis of rotation Y, to the neutral position of the output shaft 8.

During the movement of the finger relative to the cam, the finger follows a path defined by the cam and performs a rotation of an angular value less than a predetermined threshold, in particular 90°, around the axis of rotation parallel to the second axis of rotation Y.

When the neutral position is reached by the output shaft 8 of the electromechanical actuator 6, the cam is configured to release the finger, so that the finger returns to its rest state.

The return to the resting state of the finger is implemented either by gravity or by means of an elastic return element, such as for example a spring.

Alternatively, a tilting movement of the sash 3 relative to the fixed frame 4 around the second axis of rotation Y towards an opening position by tilting can also be implemented by supplying electrical energy to the electromechanical actuator 6, so as to drive the main flexible element 9 around the winding pulley 15.

Thus, the driving of the main flexible element 9 around the winding pulley 15 is controlled by the electric power supply of the electromechanical actuator 6.

In this way, the electromechanical actuator 6 makes it possible to slow down the tilting movement of the leaf 3 with respect to the fixed frame 4 around the second axis of rotation Y towards an open position. The braking of the tilting movement of the sash 3 relative to the fixed frame 4 depends on the drive speed of the main flexible element 9 around the winding pulley 15.

Preferably, the window 2 comprises a device for holding the sash 3 in the closed position relative to the fixed frame 4, when the locking elements of the fitting system 31 are driven between the locked state and the second unlocked state, that is to say to allow the tilting of the leaf 3 relative to the fixed frame 4 around the second axis of rotation Y, and vice versa.

Thus, the device for holding the sash 3 in the closed position relative to the fixed frame 4 makes it possible to guarantee the possibility of changing between two states of the locking elements of the fitting system 31, in particular the locked state and the second unlocked state, by means of the motorized drive device 5, as well as guaranteeing the possibility of moving the sash 3 relative to the fixed frame 4 following a closing movement by tilting around the second axis of rotation Y.

As visible to figures 1 to 3 , this device for holding in the closed position can be achieved by means of a locking mechanism 45.

Thus, when driving the locking elements of the fitting system 31 from the locked state to the second unlocked state, to allow the tilting of the leaf 3 relative to the fixed frame 4, either by electrically actuating the electromechanical actuator 6, or by manually actuating the handle 19, the sash 3 is held against the fixed frame 4, although the locking elements of the fitting system 31 are temporarily placed in the first unlocked state, to allow the pivoting of the sash 3 to fixed frame 4.

In this way, keeping the sash 3 in the closed position relative to the fixed frame 4 by means of the blocking mechanism 45, whatever the state of the locking elements of the fitting system 31, makes it possible to guarantee the passage of locking elements of the fitting system 31 from one state to another, without risk of opening the leaf 3 ajar relative to the fixed frame 4 by a pivoting movement around the first axis of rotation X.

Here, the locking mechanism 45 comprises a first part provided at the level of the fixed frame 4, in particular at the level of the lower crosspiece 4b of the fixed frame 4, and configured to cooperate with a second part of the locking mechanism 45 provided at the level of the sash 3, in particular the frame 30 of the sash 3.

In practice, the blocking mechanism 45 is produced by means of a lock-type system comprising a striker plate and a bolt.

In such a case, the positions of the mobile element 27 of the fitting system 31 correspond to the states of the locking elements of the fitting system 31 described with reference to the figures 1 to 4 .

In this exemplary embodiment, the first part of the locking mechanism 45 provided at the level of the fixed frame 4 comprises a housing, not shown. the housing is made in a box 45a which is fixed to the fixed frame 4. In addition, the second part of the locking mechanism 45 provided at the level of the opening 3 comprises a pin 48 retractable. The pin 48 is arranged at the level of a housing 45b which is fixed to the opening 3. The pin 48 of the second part of the locking mechanism 45 is configured to cooperate with the housing of the first part of the locking mechanism 45, when the sash 3 is in the closed position relative to the fixed frame 4, as well as during a tilting movement of the sash 3 relative to the fixed frame 4.

In the absence of unlocking of the locking mechanism 45, in particular by the user, the locking mechanism 45 prevents a movement of the leaf 3 relative to the fixed frame 4 following a movement of rotation around the first axis of rotation X .

A pivoting movement of the sash 3 relative to the fixed frame 4 around the first axis of rotation X is implemented by manually positioning the handle 19 in the position corresponding to the state where the locking elements of the fitting system 31 are in the first unlocked state, that is to say to allow a pivoting movement around the first axis of rotation X, then by exerting pressure on the opening 3, in particular by means of the handle 19, so to allow the pin 48 of the second part of the locking mechanism 45 to come out relative to the housing of the first part of the locking mechanism 45.

Each box 45a, 45b is fixed to the fixed frame 4 or to the leaf 3 by means of fixing elements, such as screw fixing elements.

As a variant, each box 45a, 45b can be integrated respectively into the fixed frame 4 or into the opening 3.

In another case, not shown, the locking mechanism 45 is arranged at the level of the fitting system 31.

By way of non-limiting example, the locking mechanism 45 can be provided at the level of the handle 19 for maneuvering the opening 3 with respect to the fixed frame 4.

In practice, the locking mechanism 45 is produced by means of a locking system integrated into the handle 19, such as for example a button or a key lock.

In such a case, the positions of the mobile element 27 of the fitting system 31 corresponding to the first and second unlocked states of the locking elements of the fitting system 31 are reversed.

In other words, the position of the movable element 27 of the fitting system 31 corresponding to the second unlocked state of the locking elements of the fitting 31, for tilting sash 3 relative to fixed frame 4, is arranged between the position of movable element 27 of fitting system 31 corresponding to the locked state of the locking elements of fitting system 31 and the position of the movable element 27 of the fitting system 31 corresponding to the first unlocked state of the locking elements of the fitting system 31, for the pivoting of the leaf 3 with respect to the fixed frame 4.

In this way, the motorized drive device 5 is configured to drive the locking elements of the fitting system 31 directly from the locked state to the second unlocked state, that is to say to allow a tilting movement of the sash 3 with respect to the fixed frame 4 around the second axis of rotation Y, and vice versa, without giving the possibility of reaching the first unlocked state, that is to say to allow a pivoting movement of the sash 3 relative to the fixed frame 4 around the first axis of rotation X.

In a first variant of the first embodiment, illustrated in figures 7 to 9 , the device for holding the sash 3 in the closed position relative to the fixed frame 4 is made through the locking elements of the fitting system 31.

In such a case, the positions of the mobile element 27 of the fitting system 31 corresponding to the first and second unlocked states of the locking elements of the fitting system 31 are reversed.

In other words, the position of the movable element 27 of the fitting system 31 corresponding to the second unlocked state of the locking elements of the fitting system 31, for the tilting of the leaf 3 with respect to the fixed frame 4, is arranged between the position of the movable element 27 of the fitting system 31 corresponding to the locked state of the locking elements of the fitting system 31 and the position of the movable element 27 of the fitting system 31 corresponding to the first unlocked state of the locking elements of the fitting system 31, for pivoting the sash 3 relative to the fixed frame 4.

In such a case, the locked state of the locking elements of the fitting system 31 corresponds to a low position of the handle 19, as in the case of figures 1 to 6 . The second unlocked state of the locking elements of the fitting system 31, for the tilting of the leaf 3 relative to the fixed frame 4, corresponds to a middle position of the handle 19. The first unlocked state of the locking elements of the fitting 31, for the pivoting of the opening 3 relative to the fixed frame 4, corresponds to a high position of the handle 19.

In this way, the motor drive device 5 is configured to drive the locking elements of the fitting system 31 directly from the locked state to the second unlocked state, that is to say to allow a tilting movement of the leaf 3 relative to the fixed frame 4 around the second axis of rotation Y, and vice versa, without going through the first unlocked state, that is to say to allow a pivoting movement of the leaf 3 relative to the fixed frame 4 around the first axis of rotation X.

Alternatively, not shown, the holding device in the closed position of the leaf 3 relative to the fixed frame 4 is made by means of magnets.

In a second variant of the first embodiment, illustrated in figure 10 , the main flexible element 9 is connected to the movable element 27 of the fitting system 31 by means of a connecting element 36.

Thus, the main flexible element 9 is attached to the movable element 27 of the fitting system 31, by means of the connecting element 36, only when the state of the locking elements of the fitting system 31 corresponds to the locked state or in the second unlocked state, that is to say to allow the tilting of the leaf 3 relative to the fixed frame 4 around the second axis of rotation Y.

Advantageously, the connecting element 36 comprises a holding element 37 and a hook 38.

In practice, one end of the first strand 9a of the main flexible element 9 is connected to a first end of the holding element 37. In addition, one end of the second strand 9b of the main flexible element 9 is connected to a second end of the holding element 37.

Thus, the connecting element 36 is retained by the main flexible element 9, regardless of the state of the locking elements of the fitting system 31 and regardless of the positioning of the movable element 27 of the fitting system 31 .

In an exemplary embodiment, the fixing of each of the first and second strands 9a, 9b of the main flexible element 9 on the holding element 37 of the connecting element 36 is implemented by means of a knot.

The fixing of each of the first and second strands of the main flexible element on the holding element of the connecting element is not limiting and can be different. In particular, it may be a fixing by screwing a fixing screw through an eyelet of the main flexible element and a hole of the holding element.

Preferably, the hook 38 is configured to move inside a groove 39 of the holding element 37, in particular following a translation movement.

Preferably, the hook 38 of the connecting element 36 comprises a slot 40 configured to cooperate with the movable element 27 of the fitting system 31, depending on the winding and unwinding of the first and second strands 9a, 9b of the main flexible element 9.

Furthermore, the holding element 37 comprises an opening 41 configured to cooperate with the movable element 27 of the fitting system 31, so as to allow the introduction and removal of the movable element 27 from the fitting system 31 by relative to the slot 40 of the hook 38, via the opening 41 made in the holding element 37.

Thus, the opening 41 of the holding element 37 opens into the groove 39 of the holding element 37.

Advantageously, when the movable element 27 of the fitting system 31 is in the position corresponding either to the locked state of the locking elements of the fitting system 31 or to the second unlocked state of the locking elements of the fitting system 31, it that is to say, to allow the tilting of the leaf 3 with respect to the fixed frame 4 around the second axis of rotation Y, the movable element 27 is configured to be housed inside the slot 40 of the hook 38 and held inside the hook 38 by means of the holding element 37, in particular by positioning the hook 38 inside the groove 39 made in the holding element 37.

Thus, following the positioning of the mobile element 27 of the fitting system 31 in the position corresponding to the locked state or the second unlocked state of the locking elements of the fitting system 31, the mobile element 27 is held by the element link 36, so that the sash 3 can either be kept in the closed position relative to the fixed frame 4 or moved relative to the fixed frame 4 following a tilting movement around the second axis of rotation Y, in particular without related discomfort to the main flexible element 9.

In addition, when the movable element 27 of the fitting system 31 is in the position corresponding to the first unlocked of the locking elements of the fitting system 31, that is to say to allow the pivoting of the opening 3 with respect to to the fixed frame 4 around the first axis of rotation X, the movable element 27 is configured to be released relative to the hook 38, in particular by positioning the hook 38 inside the groove 39 provided in the maintenance 37.

Thus, following the positioning of the mobile element 27 of the fitting system 31 in the position corresponding to the first unlocking of the locking elements of the fitting system 31, the mobile element 27 of the fitting system 31 is free with respect to to the connecting element 36, so that the sash 3 can be moved relative to the fixed frame 4 following a pivoting movement around the first axis of rotation X, in particular without discomfort linked to the main flexible element 9.

In practice, in the case where the mobile element 27 of the fitting system 31 is in the position corresponding to the locked state of the locking elements of the fitting system 31, a first holding position of the mobile element 27 by means of the hook 38 corresponds to a position of the hook 38 with respect to the holding element 37, in which the hook 38 is located at the level of a first end of the groove 39 of the holding element 37, in particular the lower end of the groove 39, in the assembled configuration of the window 2 with respect to the building.

In the case where the mobile element 27 of the fitting system 31 is in the position corresponding to the second unlocked state of the locking elements of the fitting system 31, a second holding position of the mobile element 27 by means of the hook 38 corresponds at a position of the hook 38 relative to the holding element 37, in which the hook 38 is located at a second end of the groove 39 of the holding element 37, in particular the upper end of the groove 39, in the assembled configuration of the window 2 with respect to the building. The second end of groove 39 is opposite the first end of groove 39.

Thus, in these two cases, the connecting element 36 engages with the mobile element 27 of the fitting system 31.

In this way, the main flexible element 9 is connected to the opening 3.

Consequently, the main flexible element 9 is attached to the movable element 27 of the fitting system 31 via the connecting element 36.

In practice, when the movable element 27 of the fitting system 31 is in the position corresponding to the locked state of the locking elements of the fitting system 31 or to the second unlocked state of the locking elements of the fitting system 31, maintaining of the movable element 27 inside the slot 40 of the hook 38 is produced by means of a wall of the groove 39 provided in the holding element 37, which being positioned opposite the slot 40 made in the hook 38.

In the case where the mobile element 27 of the fitting system 31 is in the position corresponding to the first unlocking of the locking elements of the fitting system 31, the release position of the mobile element 27 with respect to the hook 38 corresponds to a position of the hook 38 relative to the retaining element 37, in which the hook 38 is located between the first and second positions for retaining the movable element 27 of the fitting system 31 relative to the connecting element 36 and , in particular, opposite the opening 41 made in the holding element 37.

Thus, the connecting element 36 is not engaged with the movable element 27 of the fitting system 31.

In this way, the main flexible element 9 is disconnected from the opening 3.

Consequently, a pivoting movement of the sash 3 relative to the fixed frame 4 around the first axis of rotation X, towards an opening position by pivoting, by exerting a traction on the sash 3, in particular by means of the handle 19 of the window 2, is facilitated, since no constraint is exerted by the main flexible element 9 on the opening 3.

During the pivoting of the sash 3 relative to the fixed frame 4 around the first axis of rotation X, in particular up to a position of maximum opening by pivoting of the sash 3 relative to the fixed frame 4, the element link 36 is retained by the main flexible element 9, while being disconnected from the opening 3.

In this way, the pivoting of the opening 3 relative to the fixed frame 4 around the first axis of rotation X can be implemented manually without discomfort related to the main flexible element 9, since the main flexible element 9 does not is not connected to the sash 3.

In addition, the sash 3 can be pivoted relative to the fixed frame 4 around the first axis of rotation X, in particular up to the maximum opening position by pivoting, without movement of the main flexible element 9.

In this second variant of the first embodiment, the main flexible element 9 extends between the opening 3 and the fixed frame 4 on the side of the window 2 opposite the side of the window 2 comprising the hinge elements 17a, 17b movement of the sash 3 relative to the fixed frame 4.

Here, the main flexible element 9 extends between the opening 3 and the fixed frame 4 on the side of the window 2 comprising the handle 19 for operating the fitting system 31.

In second and third embodiments shown in figures 11 to 13 , elements similar to those of the first embodiment bear the same references and operate as explained above. In the following, only what distinguishes these embodiments from the previous one is mainly described. In what follows, when a reference sign is used without being reproduced on one of the figures 11 to 13 , it corresponds to the object bearing the same reference on one of the figures 1 to 10 .

We now describe, with reference to the figure 11 , the integration of the motorized drive device 5 at the level of the tilt-and-turn window 2, according to the second embodiment.

In this second embodiment shown in figure 11 , the flexible element 9 comprises a main flexible element 9', as well as at least one additional flexible element 9".

Here, the flexible element 9 comprises two additional flexible elements 9".

Following the displacement of the movable element 27 of the fitting system 31 into a position corresponding to one of the states of the locking elements of the fitting system 31 by means of the motorized drive device 5, the electromechanical actuator 6 is configured to be electrically actuated, so as to drive the output shaft 8 of the electromechanical actuator 6 to the neutral position, in which at least one strand of each additional flexible element 9" is relaxed.

Advantageously, the main flexible element 9' makes it possible, on the one hand, to move the sash 3 relative to the fixed frame 4 following a tilting movement around the second axis of rotation Y and, on the other hand, to achieve a change between two states of the locking elements of the fitting system 31, either the locked state, the first unlocked state or the second unlocked state, by driving the movable element 27 of the fitting system 31 via additional flexible elements 9".

Here and as shown in figure 11 , the electromechanical actuator 6 is of the tubular type.

Here, the motorized drive device 5 also comprises a pulley 15 for winding the main flexible element 9'. The winding pulley 15 is driven in rotation by the output shaft 8 of the electromechanical actuator 6.

Advantageously, the motorized drive device 5 is a subassembly preassembled before assembly, in the example on the fixed frame 4, and comprising at least the electromechanical actuator 6, the winding pulley 15, the main flexible element 9', the additional flexible elements 9" and the electronic control unit 10.

Here, the motorized drive device 5 also comprises at least one angle transmission pulley 21, 33.

In the exemplary embodiment illustrated in figure 11 , the motorized drive device 5 comprises a first angle transmission pulley 21 mounted on the fixed frame 4, in particular on a side upright 4c of the fixed frame 4. In addition, the motorized drive device 5 comprises a second bevel gear pulley 33 mounted on the sash 3, in particular on a side upright of the frame 30 of the sash 3.

The main flexible element 9' is configured to cooperate with the first and second bevel pulleys 21, 33, when the main flexible element 9' is driven by the electromechanical actuator 6.

In this second embodiment, the electromechanical actuator 6, the winding pulley 15 and the first and second angle transmission pulleys 21, 33 are similar to those previously described in relation to the first embodiment.

Here, the main flexible element 9' is kept under tension regardless of the state of the locking elements of the fitting system 31 and, in particular, regardless of the position of the movable element 27 of the fitting system 31.
