Description

[0001] The present invention relates to a sliding window for a building comprising a locking device for the opening relative to the fixed frame in a locked half-open position, a home automation installation comprising such a sliding window and a method for controlling in operation a motorized drive device for such a sliding window for a building.

[0002] In general, the present invention relates to the field of windows comprising a motorized drive device that moves a sash relative to a fixed frame in a sliding motion, between at least a first position and at least a second position. A motorized drive device for such a window includes an electromechanical actuator.

[0003] US patent 3,352,586 A is already known, describing a sliding window for a building comprising a fixed frame, a sash, and a locking device for the sash relative to the fixed frame. The locking device comprises a first subassembly and a second subassembly. The first subassembly is fixed to the fixed frame. The second subassembly is fixed to the sash. The second subassembly includes a movable finger about an axis of rotation and a spring return element. The spring return element is configured to bring the movable finger to a rest position. The movable finger is configured to cooperate with the first subassembly when the sash moves relative to the fixed frame, so as to lock the sash against the fixed frame.

[0004] The first subassembly comprises a rack. The movable finger of the second subassembly is configured to cooperate with notches of the rack of the first subassembly.

[0005] The locking mechanism is configured to lock the sash relative to the fixed frame in an open position, a closed position, and a locked ajar position. The locked ajar position is located between the open and closed positions of the sash relative to the fixed frame.

[0006] However, such a locking device for a sliding window has the disadvantage of implementing the locking of the moving finger relative to the rack, depending on a manual movement of the opening relative to the fixed frame.

[0007] Therefore, such a sliding window requires the opening sash to be operated manually relative to the fixed frame, in particular by means of an operating handle located on the sash.

[0008] Furthermore, unlocking the opening from the fixed frame can only be done manually by pulling on a chain connected to the moving finger.

[0009] Therefore, such a locking device is not compatible with a motorized drive device configured to move the opening sash relative to the fixed frame by sliding.

[0010] The present invention aims to resolve the aforementioned drawbacks and to provide a sliding window for a building comprising a motorized drive device for moving an opening relative to a fixed frame in a sliding motion, a home automation installation comprising such a sliding window, and a method for controlling in operation a motorized drive device of such a sliding window for a building, allowing the opening to be locked relative to the fixed frame in a half-open position, and unlocking the opening relative to the fixed frame from the locked half-open position.

[0011] To this end, the present invention relates, according to a first aspect, to a sliding window for a building comprising: a fixed frame, at least one opening, and a first locking device for the opening relative to the fixed frame in a locked half-open position, the locked half-open position being disposed between an open position and a closed position of the opening relative to the fixed frame, the first locking device comprising a movable arm around an axis of rotation.

[0012] According to the invention, the window also includes: a motorized drive device configured to move the opening by sliding relative to the fixed frame, and a second locking device for the opening relative to the fixed frame in the closed position.

[0013] The motorized drive system includes: an electronic control unit, an electromechanical actuator, the electromechanical actuator comprising an electric motor, a flexible element, the flexible element being configured to drive the opening relative to the fixed frame when the electromechanical actuator is electrically activated, and a drive arm, the drive arm being connected, on one side, to the opening and, on the other side, to the flexible element.

[0014] The drive arm cooperates with the moving arm of the first locking device.

[0015] The movable arm maintains the drive arm between the locked half-open position and the closed position of the sash relative to the fixed frame, following the crossing of the locked half-open position, during a movement of the sash relative to the fixed frame from an open position to the closed position, implemented by the electrical activation of the electromechanical actuator.

[0016] In addition, the first locking device includes: a first elastic return element disposed between the movable arm and an assembly element, the assembly element being configured to fix the first locking device on a fixed part of the window, the movable arm being mounted in rotation relative to the assembly element around the axis of rotation, and a device for releasing the movable arm relative to the drive arm, the release device being activated, following the locking of the sash relative to the fixed frame in the closed position, by means of the second locking device.

[0017] Thus, the first locking device allows the opening to be locked relative to the fixed frame in the locked half-open position by means of the motorized drive device.

[0018] In this way, the first locking device makes it possible to guarantee the ventilation of the building in a secure manner by a slight opening of the opening relative to the fixed frame, in particular by means of simple parts.

[0019] In addition, the unlocking of the opening relative to the fixed frame in connection with the first locking device is implemented by means of the motorized drive device configured to generate a movement of the opening relative to the fixed frame passing through the closed and locked position of the opening relative to the fixed frame, by means of the second locking device.

[0020] In this way, the unlocking of the opening relative to the fixed frame is implemented solely by means of the motorized drive device.

[0021] Furthermore, the electronic control unit of the motorized drive device allows the movement of the opening relative to the fixed frame to lock the opening relative to the fixed frame in the locked half-open position and to unlock the opening relative to the fixed frame from the locked half-open position.

[0022] In this way, the achievement of the locked half-open position by the motorized drive device is implemented in a repeatable manner, while ensuring a clear stop of the opening against the fixed frame by means of the first locking device.

[0023] The first locking device thus makes it possible to prevent, or at least delay, an attempt at intrusion by an individual.

[0024] According to an advantageous feature of the invention, the window also includes a control device for the second locking device. Furthermore, the drive arm supports the control device for the second locking device.

[0025] According to another advantageous feature of the invention, the movable arm includes a stop. Furthermore, the stop of the movable arm limits the stroke of the drive arm, after it has passed the stop corresponding to a maximum locked half-open position, during movement of the sash relative to the fixed frame from an open position to the closed position.

[0026] According to an advantageous feature of the invention, the release device comprises a cam movable about an axis of rotation. Furthermore, the cam is configured to be displaced relative to the movable arm.

[0027] According to another advantageous feature of the invention, the first locking device includes a second elastic return element disposed between the movable arm and the cam.

[0028] According to another advantageous feature of the invention, the drive arm is connected to the flexible element by means of a shuttle. Furthermore, the shuttle cooperates with the movable arm of the first locking device.

[0029] According to another advantageous feature of the invention, the release device is activated by means of the shuttle, during a movement of the opening relative to the fixed frame from the closed position to an open position of the opening relative to the fixed frame.

[0030] According to another advantageous feature of the invention, the first locking device also includes a device for adjusting the position of the release device relative to the moving arm.

[0031] The present invention relates, according to a second aspect, to a home automation installation comprising a sliding window according to the invention.

[0032] This home automation system has characteristics and advantages similar to those described previously, in relation to the sliding window according to the invention.

[0033] According to a third aspect, the present invention relates to a method of controlling in operation a motorized drive device for a sliding window for a building, as mentioned above.

[0034] According to the invention, the method includes at least one step of moving the opening relative to the fixed frame from an open position to the locked half-open position of the opening relative to the fixed frame, implemented by the electrical activation of the electromechanical actuator.

[0035] This control method has characteristics and advantages similar to those described previously, in relation to the sliding window according to the invention.

[0036] According to another advantageous feature of the invention, when moving the sash relative to the fixed frame from the open position to the locked half-open position of the sash relative to the fixed frame, the movable arm is moved relative to a fixed part of the window, firstly, by a first rotational movement around an axis of rotation and, secondly, by a second rotational movement around the axis of rotation, the first rotational movement of the movable arm is opposite to the second rotational movement of the movable arm.

[0037] According to another advantageous feature of the invention, when moving the opening relative to the fixed frame from the open position to the locked half-open position of the opening relative to the fixed frame, a cam is moved relative to the moving arm by a rotational movement around an axis of rotation.

[0038] According to another advantageous feature of the invention, the method further comprises at least the following steps: following the attainment of the locked half-open position of the opening relative to the fixed frame, a monitoring step of the position of the opening relative to the fixed frame, following the detection of a movement of the opening relative to the fixed frame during the monitoring step, a step of determining an intrusion attempt, and in the case where an intrusion attempt has been determined during the step of determining an intrusion attempt, a step of moving the opening relative to the fixed frame from the locked half-open position to the locked closed position.

[0039] Other features and advantages of the invention will become apparent in the description below.

[0040] The attached drawings are given as non-exhaustive examples: there figure 1is a partial schematic perspective view of a sliding window according to a first embodiment of the invention, where a first opening sash is in a closed position relative to a fixed frame and where a cover on a crossbar is removed; the figure 2 is a view analogous to the figure 1 , where the first opening is in a locked, partially open position relative to the fixed frame; the figure 3 is a view analogous to Figures 1 And 2 where the first opening is in an open position relative to the fixed frame; the figure 4 is a partial schematic perspective view of the window illustrated in figures 1 to 3 , where a first locking device is shown; the figures 5 to 12 are top views of the window similar to that of the figure 4 illustrating different states of the first locking device; and the figure 13is a schematic front view of part of the sliding window illustrated in figures 1 to 3 illustrating the first locking device according to a second embodiment.

[0041] First, we describe, with reference to figures 1 to 3 , a home automation installation according to the invention and installed in a building comprising an opening 1, in which is arranged a sliding window 2, according to a first embodiment of the invention.

[0042] Sliding window 2 can also be called a sliding bay window.

[0043] The present invention applies to sliding windows and sliding patio doors, whether or not equipped with transparent glazing.

[0044] Window 2 includes at least one opening 3a, 3b and a fixed frame 4.

[0045] Here, and as illustrated in figures 1 to 3 , window 2 includes a first opening 3a and a second opening 3b.

[0046] Window 2 also includes a motorized drive device 5 configured to slide an opening 3a relative to the fixed frame 4.

[0047] Here, the motorized drive device 5 is configured to move by sliding only one of the first and second openings 3a, 3b relative to the fixed frame 4, in particular the first opening 3a.

[0048] Here, and as illustrated in figures 1 to 3 , the second opening 3b is manually movable, in particular by the action of a user exerting force on a handle, not shown, of the second opening 3b.

[0049] Alternatively, the second opening 3b is fixed.

[0050] The number of window openings is not limited and can be different, in particular equal to three.

[0051] Each opening 3a, 3b includes a frame 15. Each opening 3a, 3b may also include at least one pane of glass 16 arranged in the frame 15.

[0052] The number of windows in the opening is not limited and can be different, in particular equal to two or more.

[0053] The frame 15 of each opening 3a, 3b comprises a top rail 15a, a bottom rail (not shown), and first and second side mullions 15c, in the assembled configuration of window 2 relative to the building, as illustrated in figures 1 to 3 .

Furthermore, the second side post 15c of the frame 15 of the first opening 3a is the side post 15c located on the left of the first opening 3a.

[0055] The first lateral upright 15c of the frame 15 of the first opening 3a is opposite the second lateral upright 15c of the frame 15 of the first opening 3a.

[0056] Similarly, the first side post 15c of the frame 15 of the second opening 3b is the side post 15c located on the right of the second opening 3b. Furthermore, the second side post 15c of the frame 15 of the second opening 3b is the side post 15c located on the left of the second opening 3b.

[0057] The first lateral upright 15c of the frame 15 of the second opening 3b is opposite the second lateral upright 15c of the frame 15 of the second opening 3b.

[0058] The fixed frame 4 comprises a top rail 4a, a bottom rail (not shown), and first and second side mullions 4c, in the assembled configuration of the window 2 relative to the building, as illustrated in figures 1 to 3 .

[0059] Here and as illustrated in figures 1 to 3The first lateral post 4c of the fixed frame 4 is the lateral post 4c located on the right of the fixed frame 4. In addition, the second lateral post 4c of the fixed frame 4 is the lateral post 4c located on the left of the fixed frame 4.

[0060] The first lateral upright 4c of the fixed frame 4 is opposite the second lateral upright 4c of the fixed frame 4.

[0061] The upper crossbar 4a, the lower crossbar and the two lateral uprights 4c of the fixed frame 4 have respectively an inner face and at least one outer face.

[0062] The inner faces of the upper rail 4a, the lower rail and the two side posts 4c of the fixed frame 4 are oriented towards the interior of the window 2 and, in particular, towards an outer edge of the frame 15 of each opening 3a, 3b.

[0063] The outer faces of the upper rail 4a, the lower rail and the two side uprights 4c of the fixed frame 4 are oriented towards the outside of the window 2.

[0064] Window 2 also includes a hardware system, not shown, located between the fixed frame 4 and each sash 3a, 3b. The hardware system of window 2 is not shown on the figures 1 to 3 , so as to make them easier to read.

[0065] The sliding window hardware system 2 allows each sash 3a, 3b to slide relative to the fixed frame 4 along a sliding direction D, in the example horizontal, in the assembled configuration of the window 2 relative to the building, as illustrated in figures 1 to 3 .

[0066] Advantageously, the hardware system includes a cremone bolt and locking elements for the first opening 3a relative to the fixed frame 4.

[0067] Here, the hardware system is mounted along the first lateral upright 15c of the frame 15 of the first opening 3a.

[0068] Here, the cremone bolt is located inside the first lateral upright 15c of the frame 15 of the first opening 3a.

[0069] Alternatively, not shown, the cremone bolt can also be partially located inside the upper rail 15a or the lower rail of the frame 15 of the first opening 3a.

[0070] Advantageously, the cremone bolt includes at least one rod. Furthermore, the cremone bolt also includes a body.

[0071] In practice, the cremone bolt body is fixed relative to the first lateral jamb 15c of the frame 15 of the first opening 3a. In addition, the rod is configured to move relative to the cremone bolt body.

[0072] Advantageously, the rod is made in several parts connected together, in particular by means of retaining elements.

[0073] Here, the movement of the cremone rod is implemented along the first lateral jamb 15c of the frame 15 of the first opening 3a, in particular in a vertical direction, in the assembled configuration of window 2 relative to the building.

[0074] Advantageously, the cremone bolt rod includes at least one hook forming a locking element. The fixed frame 4, in particular the first lateral jamb 4c of the fixed frame 4, includes at least one strike plate, not shown. Each hook of the rod is configured to cooperate with the aforementioned strike plate of the fixed frame 4.

[0075] The rod hooks, as well as the strike plates provided in the fixed frame 4, form at least in part the locking elements of the hardware system.

[0076] When the rod hooks are engaged in the strike plates of the fixed frame 4, the first opening 3a is in a so-called closed locked position, which is both closed and locked relative to the fixed frame 4.

[0077] When the rod hooks are disengaged from the strike plates of the fixed frame 4, the first opening 3a is in an unlocked position from the fixed frame 4, and can also be closed or open.

[0078] The upper rail 4a of the fixed frame 4 includes a sliding rail 11a to allow the first sash 3a to slide and a sliding rail, not shown, to allow the second sash 3b to slide. The lower rail of the fixed frame 4 also includes two sliding rails, one for the first sash 3a and the other for the second sash 3b.

[0079] Thus, each of the upper 4a and lower cross members of the fixed frame 4 includes a first sliding rail 11a or equivalent for the first opening 3a and a second sliding rail or equivalent for the second opening 3b.

[0080] In this way, the first and second openings 3a, 3b are configured to move respectively along the first and second sliding rails 11a and equivalents.

[0081] In practice, the first and second sliding rails 11a or equivalents are arranged parallel to each other. Furthermore, the first and second sliding rails 11a or equivalents are offset from each other according to the thickness of the fixed frame 4.

[0082] Window 2 includes sliding elements, not shown, allowing movement of each opening 3a, 3b relative to the fixed frame 4. The sliding elements are arranged inside the first and second sliding rails of the lower crossbar.

[0083] In practice, the sliding elements include rollers arranged under the first and second openings 3a, 3b. The rollers are configured to roll inside the first and second sliding rails of the lower crossbar.

[0084] A sliding opening position, partial or maximum, of each opening 3a, 3b relative to the fixed frame 4 corresponds to a building ventilation position.

[0085] The motorized drive device 5 allows the first opening 3a to be moved automatically by sliding relative to the fixed frame 4, in particular between the maximum opening position by sliding of the first opening 3a relative to the fixed frame 4 and the closed position of the first opening 3a relative to the fixed frame 4.

[0086] The motorized drive device 5 includes an electromechanical actuator 6. The electromechanical actuator 6 includes an electric motor 7. The electromechanical actuator 6 also includes an output shaft 8, which is rotatable about an axis of rotation X.

[0087] Here, the rotation axis X is parallel to the sliding direction D of the first opening 3a with respect to the fixed frame 4 and, in this case, of the second opening 3b with respect to the fixed frame 4.

[0088] Advantageously, the electric motor 7 of the electromechanical actuator 6 is of the variable speed type. The electric motor 7 is configured to drive the output shaft 8 in rotation according to at least a first rotational speed setpoint and a second rotational speed setpoint, so that the movement of the first opening 3a relative to the fixed frame 4 is implemented either at a first speed or at a second speed, different from the first speed.

[0089] Here, the electric motor 7 is of the electronically commutated brushless type, also called "BLDC" (acronym for the Anglo-Saxon term BrushLess Direct Current) or "permanent magnet synchronous".

[0090] Preferably, the electromechanical actuator 6 is of the reversible type.

[0091] Here, the electromechanical actuator 6 is controlled by an electronic control unit 10 belonging to the motorized drive device 5. Such an electronic control unit 10 makes it possible to determine the position of the first opening 3a relative to the fixed frame 4, as well as to trigger movements of the first opening 3a relative to the fixed frame 4 by means of the electromechanical actuator 6, autonomously.

[0092] Preferably, the electronic control unit 10 associated with the electromechanical actuator 6 is configured to detect a movement of the first opening 3a relative to the fixed frame 4 implemented manually and, more particularly, by an element external to the electromechanical actuator 6 acting on the first opening 3a.

[0093] Advantageously, the electromechanical actuator 6 is devoid of a brake, in particular to allow the electromechanical actuator 6 to be reversible.

[0094] The electromechanical actuator 6 is arranged on a fixed part relative to the window 2, in particular relative to the fixed frame 4.

[0095] The electromechanical actuator 6 may also include a reduction device, in particular a geared one, not shown.

[0096] The electromechanical actuator 6 may also include a limit switch and / or obstacle detection device, not shown. This detection device may be mechanical or electronic.

[0097] Advantageously, the electric motor 7 and, optionally, the reduction device are arranged inside a housing 17 of the electromechanical actuator 6.

[0098] Here, the electromechanical actuator 6 is of the tubular type.

[0099] As illustrated in figures 1 to 3The motorized drive device 5 also includes a flexible element 9. The flexible element 9 is driven in movement by the electromechanical actuator 6.

[0100] The flexible element 9 is configured to drive the first opening 3a in movement relative to the fixed frame 4, when the electromechanical actuator 6 is electrically activated.

[0101] Here, the flexible element 9 comprises a first strand 9a and a second strand 9b.

[0102] The flexible element 9 can have a circular cross-section. The cross-section of the flexible element is not limited and can be different, in particular square, rectangular or oval.

[0103] In practice, the flexible element 9 is a cable or cord.

[0104] It can be made of a synthetic material, such as nylon or polyethylene with a very high molar mass. Thus, the use of a flexible element 9 made of synthetic material makes it possible to minimize the diameter of the pulleys of the motorized drive device 5.

[0105] The material of the flexible element is not limited and can vary. In particular, it can be steel.

[0106] The motorized drive unit 5 also includes a drive arm 18.

[0107] 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.

[0108] Thus, the drive arm 18 is configured to secure the flexible element 9 to the first opening 3a.

[0109] Here, the drive arm 18 is connected to the flexible element 9 by means of a shuttle 45.

[0110] Advantageously, the shuttle 45 is fixed to the flexible element 9, in particular to the second strand 9b of the flexible element 9, by means of fixing elements, not shown.

[0111] In practice, the fixing elements of the flexible element 9, in particular of the second strand 9b of the flexible element 9, on the shuttle 45 can be of the cable clamp type.

[0112] Here, these fixing elements are screws, for example two of them, configured to be screwed respectively into a screw hole of the shuttle 45, so as to fix the flexible element 9, in particular the second strand 9b of the flexible element 9, by wedging between the head of the screws and a surface of the shuttle 45.

[0113] Here, the drive arm 18 is fixed directly onto the first opening 3a.

[0114] Advantageously, the drive arm 18 is connected, on the one hand, to the frame 15 of the first opening 3a and, more particularly, to the first lateral post 15c of the frame 15 of the first opening 3a and, on the other hand, to the flexible element 9.

[0115] Preferably, the drive arm 18 is fixed, therefore immobile, relative to the frame 15 of the first opening 3a.

[0116] In this way, the connection between the drive arm 18 and the frame 15 of the first opening 3a is simplified and helps to minimize the costs of obtaining the window 2.

[0117] 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.

[0118] Thus, the drive arm 18 is configured to hook onto the flexible element 9 arranged above the fixed frame 4 and, more particularly, arranged inside a cross member 47.

[0119] 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.

[0120] Thus, the drive arm 18 is fixed on 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.

[0121] In this way, fixing the drive arm 18 on the first side post 15c of the frame 15 of the first opening 3a is made easier compared to fixing the drive arm 18 on an internal area of ​​the frame 15 of the first opening 3a, in particular located at the sliding rail 11a of the upper rail 4a of the fixed frame 4, in the assembled configuration of the window 2.

[0122] Advantageously, the drive arm 18 is assembled with the first opening 3a on the inner side of the frame 15 of the first opening 3a, in the assembled configuration of the window 2 relative to the building.

[0123] The inner side of the frame 15 of the first opening 3a is oriented towards the interior of the building, in the assembled configuration of window 2 with respect to the building.

[0124] Advantageously, the flexible element 9 is connected to the drive arm 18, regardless of the state of the locking elements of the hardware system, i.e. in both the locked and unlocked states of the first opening 3a relative to the fixed frame 4.

[0125] Thus, the flexible element 9 is permanently connected to the drive arm 18, in the assembled configuration of the motorized drive device 5 on the window 2.

[0126] In this way, the connection between the flexible element 9 and the drive arm 18 is simplified and helps to minimize the costs of obtaining window 2.

[0127] In practice, the drive arm 18 is fixed on the first lateral post 15c of the frame 15 of the first opening 3a, configured to cooperate with the first lateral post 4c of the fixed frame 4, when reaching the closed position of the first opening 3a relative to the fixed frame 4.

[0128] In practice, the drive arm 18 is fixed to the first side post 15c of the frame 15 of the first opening 3a by means of fixing elements, not shown, in particular removable by means of a tool.

[0129] Here, the fixing elements of the drive arm 18 on the first opening 3a are screw fixing elements.

[0130] The type of attachment elements for the drive arm on the first opening sash is not limited and may vary. In particular, it may include elastic snap-fit ​​attachment elements.

[0131] Advantageously, the drive arm 18 is fixed on the frame 15 of the first opening 3a, following the installation of the first opening 3a inside the fixed frame 4 and, in this case, also of the second opening 3b inside the fixed frame 4, an installation during which the adjustments of the hardware system and the sliding elements are implemented.

[0132] Thus, the adjustments of the hardware system and sliding elements can be implemented manually and conventionally, as for a window without the motorized drive device 5.

[0133] Preferably, the drive arm 18 is fixed on 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.

[0134] Alternatively, and not shown, window 2 includes a cover element. The cover element is configured to cover at least the drive arm 18.

[0135] In one embodiment, the cover element is configured to cover only the drive arm 18.

[0136] In another embodiment, the trim element is configured to cover the drive arm 18 as well as part or all of the first side post 15c of the frame 15 of the first opening 3a, in particular according to the height of the frame 15, in the assembled configuration of the window 2 relative to the building.

[0137] In practice, the trim 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.

[0138] Advantageously, the fixing elements of the trim element are configured to cooperate with the drive arm 18 and / or with the first side post 15c of the frame 15 of the first opening 3a.

[0139] The fixing elements of the trim element in relation to the first opening 3a may be, in particular, fixing elements by elastic snap-fit ​​or by screwing.

[0140] Preferably, the cross member 47 includes a slide 36. In addition, the shuttle 45 is configured to slide inside the slide 36 of the cross member 47.

[0141] Thus, the movements of the shuttle 45, during the training of the flexible element 9, are guided inside the slide 36 of the cross member 47.

[0142] In the example of implementation illustrated in figures 1 to 3 The motorized drive device 5 includes a winding pulley 19 of the flexible element 9. The winding pulley 19 is driven in rotation by the output shaft 8 of the electromechanical actuator 6.

[0143] 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 winding pulley 19.

[0144] Advantageously, the first end of each of the first and second strands 9a, 9b of the flexible element 9 is attached respectively to the first part or the second part of the winding pulley 19 by means of fastening elements 46.

[0145] 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 the second part of the winding pulley 19.

[0146] In practice, the fixing elements 46 at the end of each of the first and second strands 9a, 9b of the flexible element 9 are cable clamp type elements.

[0147] Here, these fixing elements 46 are screws, in particular of the self-tapping type, screwing 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.

[0148] Here, the winding direction, respectively unwinding direction, of the first strand 9a of the flexible element 9 around the first part of the winding pulley 19 is opposite to the winding direction, respectively unwinding direction, of the second strand 9b of the flexible element 9 around the second part of the winding pulley 19.

[0149] Thus, when moving the first opening 3a relative to the fixed frame 4 in a first direction of sliding, in particular when moving from the closed position to an open position of the first opening 3a relative to the fixed frame 4, the first strand 9a of the flexible element 9 winds around the first part of the winding pulley 19, while the second strand 9b of the flexible element 9 unwinds around the second part of the winding pulley 19.

[0150] Furthermore, when moving the first opening 3a relative to the fixed frame 4 in a second direction of sliding, in particular when moving from an open position to the closed position of the first opening 3a relative to the fixed 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 winding pulley 19.

[0151] The second direction of sliding of the first opening 3a relative to the fixed frame 4 is opposite to the first direction of sliding.

[0152] 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 reverse to the direction of rotation of the second strand 9b of the flexible element 9 around the second part of the winding pulley 19.

[0153] Advantageously, the sliding direction of the first opening 3a relative to the fixed frame 4 is determined according to the direction of rotation of the output shaft 8 of the electromechanical actuator 6. In addition, the direction of rotation of the winding pulley 19 is determined by the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

[0154] Thus, the direction of rotation of the first strand 9a and 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.

[0155] 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.

[0156] Control means for the electromechanical actuator 6 allow the sliding movement of the first opening 3a relative to the fixed frame 4 to be controlled. These control means include at least the electronic control unit 10. The electronic control unit 10 is configured to activate the electric motor 7 of the electromechanical actuator 6 and, in particular, to allow the supply of electrical energy to the electric motor 7.

[0157] 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 fixed frame 4.

[0158] In this way, window 2 includes the electronic control unit 10. More specifically, the electronic control unit 10 is integrated into the motorized drive device 5.

[0159] Advantageously, the motorized drive device 5 is a pre-assembled sub-assembly prior to mounting, in the example on the cross member 47, which includes at least the electromechanical actuator 6, the winding pulley 19, the flexible element 9 and the electronic control unit 10.

[0160] The motorized drive device 5 is controlled by a control unit. The control unit can be, for example, a local control unit 12.

[0161] The local control unit 12 can be connected via 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 distributed throughout the building.

[0162] The electronic control unit 10 also includes a command receiving module, in particular for radio commands issued by a command transmitter, such as the local control unit 12 or the central control unit 13, these commands being intended to control the motorized drive device 5. The command receiving module can also allow the reception of commands transmitted by wired means.

[0163] 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, temperature, humidity, wind speed, a measurement of an indoor or outdoor air quality parameter or even presence.

[0164] 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.

[0165] The electronic control unit 10 can be operated from the local control unit 12. The local control unit 12 is equipped with a control keypad. The control keypad of the local control unit 12 includes selection elements and, optionally, display elements.

[0166] By way of example, and not exhaustively, selection elements can be push buttons or touch-sensitive keys, and display elements can be light-emitting diodes, an LCD (Liquid Crystal Display) or TFT (Thin Film Transistor) display. Selection and display elements can also be implemented using a touchscreen.

[0167] The local control unit 12 can be a fixed or mobile control point. A fixed control point corresponds to a control box intended to be fixed to a wall of the building, to a face of the frame 15 of the first opening 3a of the window 2 or to a face of the fixed frame 4 of the window 2. A mobile control point corresponds to a remote control.

[0168] The local control unit 12 allows the electronic control unit 10 to be controlled directly according to a selection made by the user.

[0169] 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.

[0170] The motorized drive device 5, in particular the electronic control unit 10, is preferably configured to execute sliding closing commands as well as sliding opening commands of the first opening 3a relative to the fixed frame 4, these commands being able to be issued, in particular, by the local control unit 12 or by the central control unit 13.

[0171] The electronic control unit 10 is thus capable of activating the electromechanical actuator 6 of the motorized drive device 5 and, in particular, of enabling the supply of electrical energy to the electromechanical actuator 6.

[0172] Here, and as illustrated in the figure 1 , the electronic control unit 10 is located inside the housing 17 of the electromechanical actuator 6.

[0173] The control means for the electromechanical actuator 6 include hardware and / or software means.

[0174] As a non-limiting example, the hardware may include at least one microcontroller.

[0175] Advantageously, the local control unit 12 includes a sensor measuring at least one parameter of the environment inside the building and integrated into this unit.

[0176] 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 based on data from the sensor measuring the environmental parameter inside the building.

[0177] Furthermore, the local control unit 12 can directly control the electronic control unit 10 associated with the motorized drive device 5 based on data from the sensor measuring the environmental parameter inside the building.

[0178] By way of non-limiting examples, an environmental parameter inside the building measured by the sensor integrated into the local control unit 12 is humidity, temperature, carbon dioxide level or the level of a volatile organic compound in the air.

[0179] 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 opening by sliding of the first opening 3a relative to the fixed frame 4.

[0180] 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 that may be issued by the central control unit 13 or ignoring a value measured by a sensor measuring at least one environmental parameter inside or outside the building, or a presence detection signal inside the building.

[0181] The motorized drive device 5 can be controlled by the user, for example by receiving a command order corresponding to a press on a selection element of the local control unit 12, such as a remote control or a fixed control point.

[0182] The motorized drive unit 5 can also be controlled automatically, for example by receiving a control command corresponding to at least one signal from at least one sensor and / or 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.

[0183] Advantageously, the motorized drive device 5 allows the first sash 3a to be automatically moved by sliding relative to the fixed frame 4 to a predetermined position between the closed position and the fully open position. This sliding movement of the first sash 3a relative to the fixed frame 4 to the predetermined position, particularly the partially open position, is initiated upon receipt of a command issued by the local control unit 12, the central control unit 13, or a sensor.

[0184] Here, a sliding movement of the first opening 3 relative to the fixed frame 4 along 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.

[0185] 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.

[0186] In practice, the electrical power supply of the electromechanical actuator 6 is controlled by a command order received by the electronic control unit 10 from the local control unit 12, the central control unit 13 or a sensor.

[0187] Here, the motorized drive device 5, in particular the electromechanical actuator 6, is powered by electricity from a power supply network. In such a case, the electromechanical actuator 6 includes a power supply cable, not shown, enabling it to receive power from the mains power supply network.

[0188] Alternatively, the motorized drive device 5, in particular the electromechanical actuator 6, is powered electrically 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.

[0189] 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.

[0190] Thus, the winding pulley 19 is arranged in the extension of the output shaft 8 of the electromechanical actuator 6 and is driven in rotation around the same axis of rotation X as the output shaft 8 of the electromechanical actuator 6.

[0191] Furthermore, the flexible element 9 forms a loop, called open, 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.

[0192] 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 first and second parts thereof.

[0193] In the example of implementation illustrated in figures 1 to 3 , the electromechanical actuator 6 is fixed to the cross member 47 by means of fixing elements 28.

[0194] In addition, the winding pulley 19 is held on the cross member 47 by means of these same fixing elements 28.

[0195] In practice, the fixing elements 28 of the electromechanical actuator 6 on the cross member 47 include supports, in particular fixing brackets.

[0196] Advantageously, these supports are fixed to the cross member 47 of the fixed frame 4 by screwing.

[0197] In practice, each support for the fasteners 28 includes at least one hole 48 for a fixing screw. In this embodiment, each support includes two holes 48 for a fixing screw.

[0198] In addition, each fixing screw passing through one of the through holes 48 is screwed into a gib, not shown, held in a groove 49 of the cross member 47, in particular in a screwing opening made in the gib.

[0199] Here, the fixing elements 28 of the electromechanical actuator 6 on the cross member 47 comprise two supports. One of these supports is assembled to a first end 6a of the electromechanical actuator 6. A second of these supports is assembled to a second end 6b of the electromechanical actuator 6. The first end 6a of the electromechanical actuator 6 is opposite the second end 6b of the electromechanical actuator 6.

[0200] Advantageously, each support for the fastening elements 28 includes at least one pin, not shown, configured to cooperate with the groove 49 formed in the cross member 47. In one embodiment, each support includes two pins.

[0201] Thus, each support is oriented and positioned relative to the cross member 47.

[0202] Advantageously, the fixing of the electromechanical actuator 6, as well as the winding pulley 19, on the supports of the fixing elements 28 is implemented by fixing parts, not shown, in particular by screwing.

[0203] Alternatively, not shown, the fixing parts of the electromechanical actuator 6, as well as the winding pulley 19, on the supports are elastic snap-fit ​​elements.

[0204] Here and as illustrated in figures 1 to 3, the flexible element 9 of the motorized drive device 5 extends along the upper cross member 4a of the fixed 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.

[0205] Thus, such an arrangement of the flexible element 9 makes it possible to guarantee the sliding movements of the first opening 3a relative to the fixed frame 4, as well as the aesthetic appearance of the window 2.

[0206] 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.

[0207] In this example of embodiment, the fixing elements of the cross member 47 on the upper cross member 4a of the fixed frame 4 are screw fixing elements.

[0208] The types of fasteners used to attach the crossbar to the top rail of the frame are not limited and may vary. These may include, in particular, elastic snap-fit ​​fasteners.

[0209] Alternatively, not shown, the electromechanical actuator 6 is fixed to the upper cross member 4a of the fixed frame 4 by means of the fixing elements 28.

[0210] Here and as illustrated in figures 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.

[0211] In practice, the motorized drive device 5 includes at least two angle return pulleys 35 spaced apart according to the length V of the cross member 47.

[0212] The angle return pulleys 35 are configured to guide the flexible element 9, in relation, in particular, to the winding pulley 19 and the drive arm 18, especially when moving the first opening 3a relative to the fixed frame 4.

[0213] At least one first angle return pulley 35 is disposed on a first side of the electromechanical actuator 6, i.e. on the side of the first end 6a of the electromechanical actuator 6. At least one second angle return pulley 35 is disposed on a second side of the electromechanical actuator 6, i.e. on the side of the second end 6b of the electromechanical actuator 6.

[0214] Here, the motorized drive device 5 includes a pair of angle return pulleys 35 arranged on the first side of the electromechanical actuator 6 at a distance determined relative to a pair of angle return pulleys 35 arranged on the second side of the electromechanical actuator 6.

[0215] In this embodiment example, the angle return pulleys 35 arranged on the second side of the electromechanical actuator 6 are hidden by a first locking device 20.

[0216] The number of angle return pulleys is not limited and can be different.

[0217] Each angle pulley 35 can be made, for example, by a free-running pulley, in other words mounted freely in rotation, in particular on the upper cross member 4a of the fixed frame 4, or by a fixed pulley, in other words fixed to its axis, in particular fixed to the upper cross member 4a of the fixed frame 4.

[0218] Each 35 angle pulley can be a pulley with a grooved wheel, usually called a sheave.

[0219] As illustrated in figures 1 to 3 , the electromechanical actuator 6 and the flexible element 9 are arranged inside the crossbar 47, configured to form a box and provided above the window 2, in particular extending at least partly above the upper crossbar 4a of the fixed frame 4.

[0220] Thus, the electromechanical actuator 6 and the flexible element 9 are concealed inside the crossbar 47, so as to guarantee the aesthetic appearance of the sliding window 2.

[0221] Similarly, the winding pulley 19 is located inside the crossbar 47 provided above the window 2.

[0222] The transom 47 may extend partially or completely in front of the fixed frame 4, in the assembled configuration of the window 2 relative to the building. In this case, the transom 47 extends at least partially beyond the fixed frame 4.

[0223] In such a case, the cross member 47 can either be positioned above the upper cross member 4a of the fixed frame 4 or positioned opposite the upper cross member 4a of the fixed frame 4, i.e. protruding towards the interior of the building, in the assembled configuration of the window 2 relative to the building.

[0224] Advantageously, the cross member 47 includes a hood, not shown, configured to provide access to the motorized drive device 5 and, more particularly, to the electromechanical actuator 6 and the flexible element 9, as well as to the winding pulley 19.

[0225] Thus, the hood allows for maintenance of the motorized drive device 5 and / or repair of it.

[0226] In one embodiment example, the hood extends along the entire length V of the cross member 47.

[0227] Alternatively, the hood extends only along part of the length V of the cross member 47.

[0228] Advantageously, the only opening 3a, among the first and second openings 3a, 3b, which can be slid by the motorized drive device 5 is an interior opening of the window 2. The interior opening 3a is arranged on the interior side relative to the building, in the assembled configuration of the window 2 in the building.

[0229] Thus, the flexible element 9, which allows the first opening sash 3a to slide relative to the fixed frame 4, is kept inaccessible from outside the building and, more specifically, from window 2, when the first opening sash 3a is in the closed position, as shown in the figure 1 , or a safe ventilation position, as shown in the figure 2 , in relation to the fixed frame 4.

[0230] The secure ventilation position, in other words a locked half-open position, is a position of the first opening 3a relative to the fixed frame 4 in which the first opening 3a is half-open relative to the fixed frame 4 and held locked by the first locking device 20. The locked half-open position is situated between the open position and the closed position of the first opening 3a relative to the fixed frame 4.

[0231] The locked half-open position is a partially open position of the first opening 3a relative to the fixed frame 4, for which the frame 15 of the first opening 3a is moved away from the fixed frame 4 by a predetermined distance, in particular on the order of a few centimeters.

[0232] Furthermore, in the case where the second opening 3b is manually movable, it can be moved by the user independently of the first opening 3a, in particular in the event of a lack of electrical power supply to the motorized drive device 5 or a failure of the motorized drive device 5.

[0233] The motorized drive device 5 allows the first opening 3a to slide automatically relative to the fixed frame 4 in the sliding direction D, by winding, respectively unwinding, the first strand 9a of the flexible element 9 around the first part of the winding pulley 19 and by unwinding, respectively winding, the second strand 9b of the flexible element 9 around the second part of the winding pulley 19.

[0234] The motorized drive device 5 thus allows the first opening 3a to be closed and opened in a motorized manner relative to the fixed frame 4, by sliding along the sliding direction D.

[0235] Advantageously, in the event of failure of the motorized drive device 5 or of a power supply failure of the motorized drive device 5, a manual sliding, in particular by the user, of the first opening 3a relative to the fixed frame 4 in the direction of sliding D can be implemented, since the electromechanical actuator 6 is reversible or following the disengagement of the flexible element 9 from the first opening 3a or following the disengagement of the drive arm 18 from the first opening 3a.

[0236] Furthermore, the use of the flexible element 9 to move the first opening 3a relative to the fixed frame 4 minimizes the costs of obtaining the motorized drive device 5, as well as minimizing the size of the motorized drive device 5, especially compared to a belt.

[0237] As indicated by the dotted line on the figure 1, window 2 also includes a second locking device 21 to lock the first opening 3a relative to the fixed frame 4 in the closed position and thus move it into the locked closed position.

[0238] In addition, window 2 includes a control device 22 for controlling the second locking device 21, as illustrated in the figure 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.

[0239] Advantageously, the second locking device 21 is part of the hardware system, mentioned earlier, of window 2.

[0240] Preferably, the drive arm 18 supports the control device 22.

[0241] Thus, the drive arm 18 and the control device 22 form a single mechanical unit.

[0242] As shown on the figure 4 The control device 22 advantageously includes a drive element 30. This drive element 30 is, on the one hand, connected to the shuttle 45 and, on the other hand, mounted for rotation relative to the drive arm 18.

[0243] Thus, the drive element 30 has a travel relative to the drive arm 18 and, more particularly, relative to a housing 38 of the drive arm 18.

[0244] Alternatively, not shown, the control device 22 comprises a plurality of drive elements 30. Each of the drive elements 30 is configured to be connected to the shuttle 45.

[0245] During the commissioning of window 2, one of the drive elements 30 is connected to the shuttle 45, depending on the positioning of the first locking device 20 relative to the cross member 47, following the sliding direction D.

[0246] Advantageously, the housing, formed by the cross member 47 and its cover, includes a slot 24 configured to allow the passage of an upper part of the drive arm 18, when the drive arm 18 moves relative to the fixed frame 4 along the sliding direction D, as illustrated in the figure 4 .

[0247] Thus, the drive arm 18 can be driven in displacement relative to the trunk, in the assembled configuration of the window 2, while being connected to the drive element 30 of the control device 22.

[0248] In this way, the upper part of the drive arm 18 is configured to move inside the slot 24 provided in the trunk.

[0249] Furthermore, a lower part of the drive arm 18 is located outside the trunk.

[0250] Preferably, the drive arm 18 and the second locking device 21 are arranged in the upper part of the first lateral post 15c of the frame 15 of the first opening 3a, in the assembled configuration of the window 2 with respect to the building.

[0251] 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.

[0252] Preferably, the second locking device 21 is arranged inside the first side post 15c of the frame 15 of the first opening 3a.

[0253] Advantageously, the second locking device 21 comprises at least a housing, a shaft (commonly called a square), a drive bell, and a bolt (not shown). The drive bell has a housing. One end of the shaft is located inside the housing of the drive bell. The bolt is configured to engage with a hole in the cremone rod.

[0254] Here, during the rotational drive of the shaft of the second locking device 21 by the control device 22, whether for locking the first opening 3a relative to the fixed frame 4 or for unlocking the first opening 3a relative to the fixed frame 4, the drive bell is driven in rotation 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 cremone rod along the lateral jamb 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.

[0255] Advantageously, the control device 22 includes an actuation mechanism for the second locking device 21 configured to drive the shaft of the second locking device 21 in rotation, when the flexible element 9 is driven by the electromechanical actuator 6.

[0256] 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 drive element, during the electrical activation of the electromechanical actuator 6, into a rotational movement of the shaft of the second locking device 21, during the locking or unlocking of the first opening 3a relative to the fixed frame 4.

[0257] 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.

[0258] We now describe, with reference to figures 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.

[0259] The first locking device 20 includes a movable arm 23 around a first axis of rotation Y1.

[0260] 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.

[0261] Here, the movable arm 23 is configured to move relative to the cross member 47 around the first axis of rotation Y1.

[0262] In this embodiment, the movable arm 23 is assembled onto the cross member 47 by means of an assembly element 25.

[0263] Here, the assembly element 25 includes an opening 26 inside which is arranged a rotation shaft 27, so as to allow a rotation movement of the movable arm 23 around the first axis of rotation Y1.

[0264] 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 joint.

[0265] Advantageously, the assembly element 25 is fixed to the cross member 47 by means of fixing elements, not shown.

[0266] The assembly element 25 is configured to fix the first locking device 20 to a fixed part of the window 2, in particular the crossbar 47.

[0267] Here, the fasteners for attaching the assembly member 25 to the cross member 47 include positioning elements inside the groove 49 of the cross member 47, such as, for example, guide pins, as well as fasteners. Each fastener is configured to pass through a through hole provided in the cross member 47 and to screw into a fastener hole in the assembly member 25.

[0268] The type of fasteners used to attach the assembly element to the cross member is not limited and may vary. These may include, in particular, elastic snap-fit ​​fasteners.

[0269] In this embodiment, the first locking device 20 rests on the cross member 47. And, more specifically, a wall of the assembly element 25 of the first locking device 20 rests on a wall of the cross member 47.

[0270] Here, the assembly element 25 of the first locking device 20 is made in the form of a stirrup.

[0271] The first locking device 20 includes a first elastic return element, not shown, disposed between the movable arm 23 and the assembly element 25.

[0272] Thus, the first elastic return element ensures that the mobile arm 23 remains in a rest position relative to the assembly element 25 and, more particularly, relative to the cross member 47.

[0273] Here, the first elastic return element is a spring, in particular of the pin type.

[0274] The type of elastic return element between the moving arm and the assembly element is not limited and may vary. It may, in particular, be a torsion spring, for example a spiral spring.

[0275] Advantageously, the first elastic return element is located on the same rotation axis Y1 as that of the mobile arm 23.

[0276] In such a case, the movable arm 23 is supported against a stop, not shown, of the assembly element 25.

[0277] Alternatively, not shown, the movable arm 23 is configured to move relative to the fixed frame 4 around the first axis of rotation Y1 and, more particularly, relative to the upper cross member 4a of the fixed frame 4.

[0278] The drive arm 18 is configured to cooperate with the movable arm 23 of the first locking device 20.

[0279] Here, the shuttle 45 is also configured to cooperate with the mobile arm 23 of the first locking device 20.

[0280] The movable arm 23 is configured to hold the drive arm 18 and, more particularly, the housing 38 of the drive arm 18, between the locked half-open position and the closed position of the first opening 3a relative to the fixed frame 4, following the crossing of the locked half-open position, during a movement of the first opening 3a relative to the fixed frame 4 from an open position to the closed position.

[0281] The first locking device 20 includes a release device 29 for the movable arm 23 relative to the drive arm 18.

[0282] The release device 29 is configured to be activated, following the locking of the first opening 3a relative to the fixed frame 4 in the closed position, by means of the second locking device 21.

[0283] Thus, the first locking device 20 allows the first opening 3a to be locked relative to the fixed frame 4 in the locked half-open position, by means of the motorized drive device 5.

[0284] In this way, the first locking device 20 makes it possible to ensure the ventilation of the building in a secure manner by a slight opening of the first opening 3a relative to the fixed frame 4, in particular by means of simple parts.

[0285] Furthermore, the unlocking of the first opening 3a relative to the fixed frame 4 in connection with the first locking device 20 is implemented by means of the motorized drive device 5 configured to generate a movement of the first opening 3a relative to the fixed frame 4 passing through the closed and locked position of the first opening 3a relative to the fixed frame 4, by means of the second locking device 21.

[0286] In this way, the unlocking of the first opening 3a relative to the fixed frame 4 is implemented only by means of the motorized drive device 5.

[0287] Furthermore, the electronic control unit 10 of the motorized drive device 5 allows the movement of the first opening 3a relative to the fixed frame 4 to lock the first opening 3a relative to the fixed frame 4 in the locked half-open position and to unlock the first opening 3a relative to the fixed frame 4 from the locked half-open position.

[0288] In this way, the achievement of the locked half-open position by the motorized drive device 5 is implemented in a repeatable manner, while ensuring a clear stop of the first opening 3a against the fixed frame 4 by means of the first locking device 20.

[0289] The first locking device 20 thus makes it possible to prohibit, or at least delay, an attempt at intrusion by an individual.

[0290] Advantageously, the release device 29 is configured to be activated by means of the drive arm 18 and, more particularly, the shuttle 45, in particular a ramp 40 of the shuttle 45, during a movement of the first opening 3a relative to the fixed frame 4 from the closed position and, more particularly, the locked closed position to an open position of the first opening 3a relative to the fixed frame 4.

[0291] 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 fixed frame 4 from the closed position to an open position of the first opening 3a relative to the fixed frame 4, makes it possible to release the drive arm 18 relative to the moving arm 23 of the first locking device 20.

[0292] In this way, the drive arm 18 is unlocked relative to the movable arm 23 of the first locking device 20 and the first opening 3a can be moved relative to the fixed frame 4 beyond the locked half-open position, following the direction of movement of the first opening 3a relative to the fixed frame 4 from the closed position to an open position.

[0293] Advantageously, the movable arm 23 includes 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 half-open position, during a movement of the first opening 3a relative to the fixed frame 4 from an open position to the closed position.

[0294] Thus, the stop 31 of the mobile arm 23 ensures that the first opening 3a remains in position relative to the fixed frame 4 in the locked half-open position.

[0295] In this way, the stop 31 of the movable arm 23 allows the drive arm 18 to be blocked and thus ensures locking in the locked half-open position, where the bearing of the drive arm 18 against the stop 31 of the movable arm 23 corresponds to the maximum half-opening of the first opening 3a relative to the fixed frame 4.

[0296] 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 fixed 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.

[0297] Thus, the drive arm 18 ensures that the free end 23a of the mobile arm 23 remains in contact with the free end 23a during movement of the first opening 3a relative to the fixed 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.

[0298] Here, the free end 23a of the movable arm 23 is the part of the movable arm 23 comprising the stop 31.

[0299] Preferably, the movable arm 23 includes 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 housing 38 of the drive arm 18.

[0300] Advantageously, the release device 29 includes a cam 32 movable about a second axis of rotation Y2. In addition, the cam 32 is configured to be displaced relative to the movable arm 23.

[0301] In this embodiment, the cam 32 is assembled on the movable arm 23.

[0302] Here, the movable arm 23 includes an opening, not shown, inside which is arranged a rotation shaft 33, so as to allow a rotational movement of the cam 32 around the second rotation Y2.

[0303] Thus, the cam 32 is mounted in rotation relative to the movable arm 23 by means of a pivot joint.

[0304] Advantageously, the first locking device 20 includes a second elastic return element 34 disposed between the movable arm 23 and the cam 32.

[0305] Thus, the second elastic return element 34 ensures that the cam 32 remains in a rest position relative to the movable arm 23.

[0306] Here, the second elastic return element 34 is a spring, in particular of the pin type.

[0307] The type of elastic return element between the moving arm and the cam is not limited and can vary. It can be, in particular, a torsion spring, for example a spiral spring.

[0308] Advantageously, the second elastic return element 34 is located on the same axis of rotation Y2 as that of the cam 32.

[0309] In such a case, the cam 32 is supported against a support stop, not shown, of the movable arm 23.

[0310] 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 fixed frame 4, both in the direction of movement from an open position to the closed position of the first opening 3a relative to the fixed frame 4 and in the direction of movement from the closed position to an open position of the first opening 3a relative to the fixed frame 4.

[0311] Thus, the ramp 40 of the shuttle 45 ensures that the first opening 3a remains in contact with the cam 32 of the release device 29 during movement of the first opening 3a relative to the fixed frame 4, regardless of the direction of movement of the first opening 3a relative to the fixed frame 4.

[0312] Here, ramp 40 is integrated into shuttle 45.

[0313] In addition, the ramp 40 of the shuttle 45 prevents the drive arm 18 from coming into contact with the mobile arm 23 of the first unlocking device 20, when the first locking device 20 is unlocked.

[0314] Following the locking of the first opening 3a relative to the fixed frame 4 in the closed position by means of the second locking device 21, and then during a movement of the first opening 3a relative to the fixed frame 4 in the direction of movement from the closed position to an open position of the first opening 3a relative to the fixed frame 4, the shuttle 45, in particular the ramp 40 of the shuttle 45, is brought into contact with the cam 32.

[0315] Thus, the movement of the shuttle 45 by means of the motorized drive device 5 makes it possible to push back the movable arm 23, against the force exerted by the second elastic return element 34, so as to disengage the stop 31 of the movable arm 23 from the drive arm 18.

[0316] 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 beyond the locked half-open position, by means of the motorized drive device 5.

[0317] Advantageously, when the first opening 3a is in the closed, unlocked position relative to the fixed frame 4, the release device 29 and, more particularly, the cam 32 of the release device 29 is in contact with the shuttle 45 and, more particularly, with the ramp 40 of the shuttle 45.

[0318] Advantageously, during the transition from the unlocked closed position of the first sash 3a relative to the fixed frame 4 to the locked closed position of the first sash 3a relative to the fixed frame 4, by means of the second locking device 21, the motorized drive device 5 moves the first sash 3a relative to the fixed frame 4 in a translational motion, as illustrated by an arrow F2, along the sliding direction D, particularly on the figure 12 .

[0319] Thus, at the end of the movement of the first opening 3a relative to the fixed frame 4, implemented by the motorized drive device 5, the first opening 3a is in the locked closed position relative to the fixed frame 4.

[0320] Advantageously, when the first opening 3a is in the locked closed position relative to the fixed frame 4, the release device 29, and more particularly the cam 32 of the release device 29, is no longer in contact with the shuttle 45, and more particularly with the ramp 40 of the shuttle 45, as illustrated in the figure 5 .

[0321] Thus, when the first opening 3a reaches the locked closed position relative to the fixed frame 4, the release device 29 is activated, in other words brought back to a rest position, in particular by means of the second elastic return element 34.

[0322] In addition, the locking of the first opening 3a relative to the fixed frame 4 in the closed position, by means of the second locking device 21, is implemented, in particular, by means of the flexible element 9, the shuttle 45 and the control device 22, as described previously.

[0323] In a second embodiment, represented in the figure 13 The elements analogous to those of the first embodiment bear the same references and function as explained above. The following mainly describes what distinguishes this embodiment from the previous one. In what follows, when a reference sign is used without being reproduced on the figure 13 , it corresponds to the object bearing the same reference on one of the figures 1 to 12 .

[0324] We now describe, in particular, with reference to the figure 13 , the first unlocking device 20, according to the second embodiment.

[0325] Advantageously, the first locking device 20 also includes an adjustment device 50 in the position of the release device 29 relative to the movable arm 23.

[0326] Thus, the adjustment device 50 makes it possible to compensate for uncertainties in the positioning of the first locking device 20 in relation to the crossbar 47 and the fixed frame 4.

[0327] In this way, the adjustment device 50 makes it possible to take into account variations in dimensions and positioning of the first locking device 20 and, more particularly, of the movable arm 23 and the release device 29 in relation to the shuttle 45 and the fixed frame 4.

[0328] Here, the release device 29 includes the cam 32, movable about a second axis of rotation Y2', not shown, and the second elastic return element 34, in a manner similar to the first embodiment.

[0329] In addition, the adjustment device 50 allows the contact length between the release device 29 and, more specifically, the cam 32 and the shuttle 45 to be adjusted.

[0330] Advantageously, the adjustment device 50 includes a plate 51. The plate 51 is adjustable in position relative to the movable arm 23, according to a direction of movement, in particular according to the sliding direction D.

[0331] Furthermore, in this embodiment example, the cam 32 is assembled on the plate 51.

[0332] Thus, the adjustment device 50 of the first locking device 20 allows the position of the release device 29 and, more particularly, of the cam 32 to be adjusted relative to the mobile arm 23, following a translational movement.

[0333] Here, the plate 51 includes an opening, not shown, inside which the rotation shaft 33 is arranged, so as to allow a rotational movement of the cam 32 around the second rotation shaft Y2'.

[0334] Thus, the cam 32 is mounted in rotation relative to the plate 51 and, more particularly, relative to the movable arm 23 by means of a pivot joint.

[0335] Advantageously, the second elastic return element 34 is arranged between the plate 51 and the cam 32.

[0336] Thus, the second elastic return element 34 ensures that the cam 32 remains in a rest position relative to the plate 51 and, more particularly, relative to the movable arm 23.

[0337] Here, the second elastic return element 34 is a spring, in particular of the pin type.

[0338] The type of elastic return element between the plate and the cam is not limited and can vary. It can be, in particular, a torsion spring, for example a spiral spring.

[0339] Advantageously, the second elastic return element 34 is located on the same axis of rotation Y2' as that of the cam 32.

[0340] In such a case, the cam 32 is supported against a support stop, not shown, of the plate 51.

[0341] Advantageously, the plate 51 includes a groove, not shown, configured to cooperate with a rib 53 formed in the movable arm 23, so as to move the plate 51 relative to the movable arm 23, following a translational movement.

[0342] Thus, the adjustment device 50, comprising at least the plate 51 and the cam 32, can be moved relative to the movable arm 23, by means of a sliding link.

[0343] Advantageously, the adjustment device 50 also includes at least one fixing element 54 of the plate 51 relative to the movable arm 23.

[0344] Advantageously, the fixing element 54 of the plate 51 relative to the movable arm 23 is a fixing screw. The fixing element 54 is configured to pass through a passage 52 provided in the plate 51 and to bear against a wall of the movable arm 23, in particular a face of the groove 53.

[0345] Thus, the positioning of the plate 51 relative to the movable arm 23 is achieved by applying pressure between the plate 51 and the movable arm 23, by means of the fixing element 54, which is here a pressure screw.

[0346] Advantageously, the passage opening 52 of the plate 51 is oblong in shape.

[0347] Alternatively, not shown, the adjustment device 50 is implemented via the mobile arm 23 which is telescopic, i.e. the mobile arm 23 comprises a first part and a second part, the first and second parts of the mobile arm 23 being configured to slide relative to each other, in particular along the sliding direction D.

[0348] In an alternative, not shown, the adjustment device 50 is implemented via the assembly element 25 connecting the movable arm 23 to the cross member 47, which can be moved inside the groove 49 of the cross member 47, in particular along the sliding direction D, and be held in position relative to the cross member 47 by means of a fixing element, in particular a pressure screw bearing against the cross member 47.

[0349] In a third embodiment, not shown, the elements analogous to those of the first and second embodiments bear the same references and function as explained above. What follows mainly describes what distinguishes this embodiment from the preceding ones. In what follows, when a reference sign is used, it corresponds to the object bearing the same reference on one of the... figures 1 to 13 .

[0350] We now describe, in particular, shuttle 45, according to the third embodiment.

[0351] Advantageously, the shuttle 45 includes a device for adjusting the position of the ramp 40 relative to a body of the shuttle 45.

[0352] Thus, the adjustment device of the ramp 40 relative to the body of the shuttle 45 makes it possible to compensate for uncertainties in the positioning of the first locking device 20 relative to the cross member 47 and the fixed frame 4.

[0353] In this way, the adjustment device of the ramp 40 relative to the body of the shuttle 45 allows consideration of variations in dimensions and positioning of the first locking device 20 and, more particularly, of the movable arm 23 and the release device 29 relative to the shuttle 45 and the fixed frame 4.

[0354] In addition, the adjustment device of the ramp 40 relative to the body of the shuttle 45 allows adjustment of the contact length between the release device 29 and, more particularly, the cam 32 and the ramp 40 of the shuttle 45.

[0355] Advantageously, the device for adjusting the position of the ramp 40 relative to the body of the shuttle 45 includes a slide, so as to move the ramp 40 relative to the body of the shuttle 45 by sliding, in particular along the sliding direction D, and at least one fixing element, in particular a pressure screw, so as to maintain the ramp 40 in position relative to the body of the shuttle 45.

[0356] In a fourth embodiment, not shown, the elements analogous to those of the first through third embodiments bear the same references and function as explained above. What follows mainly describes what distinguishes this embodiment from the preceding ones. In what follows, when a reference sign is used, it corresponds to the object bearing the same reference on one of the... figures 1 to 13 .

[0357] We now describe, in particular, the control device 22, according to the fourth embodiment.

[0358] Advantageously, the control device 22 includes a device for adjusting the position of the drive element 30 relative to the drive arm 18.

[0359] Thus, the adjustment device of the drive element 30 relative to the drive arm 18 makes it possible to compensate for uncertainties in the positioning of the first locking device 20 relative to the cross member 47 and the fixed frame 4.

[0360] In this way, the adjustment device of the drive element 30 relative to the drive arm 18 makes it possible to take into account variations in dimensions and positioning of the first locking device 20 and, more particularly, of the movable arm 23 and the release device 29 relative to the shuttle 45 and the fixed frame 4.

[0361] In addition, the adjustment device of the drive element 30 relative to the drive arm 18 allows adjustment of the contact length between the release device 29 and, more particularly, the cam 32 and the shuttle 45.

[0362] Advantageously, the device for adjusting the position of the drive element 30 relative to the drive arm 18 includes a slide, so as to move the drive element 30 by sliding relative to an element of the control device 22, in particular along the sliding direction D, and at least one fixing element, in particular a set screw, so as to maintain the drive element 30 in position relative to the element of the control device 22.

[0363] We now describe, with reference to figures 5 to 12 , a method for controlling the operation of the motorized drive device 5 of the sliding window 2 for a building according to the invention.

[0364] Advantageously, the operating control method of the motorized drive device 5 includes a first control step, so as to position the first opening 3a relative to the fixed frame 4 in the locked half-open position.

[0365] Here, the first control step is implemented by issuing a control order to the electronic control unit 10 of the motorized drive device 5, in particular by means of one of the local control units 12 or central control units 13 or even a sensor.

[0366] The first ordering step can therefore be implemented manually, in particular by the user, or automatically.

[0367] Advantageously, following the first control step, the process includes a first step of moving the first opening 3a relative to the fixed frame 4 from the closed position to an open position, in which the shuttle 45 is positioned beyond the first locking device 20 along the sliding direction D of the first opening 3a relative to the fixed frame 4.

[0368] When the shuttle 45 is positioned beyond the first locking device 20 along 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 control device 22, is also positioned beyond the first locking device 20 along the sliding direction D of the first opening 3a relative to the fixed frame 4.

[0369] In this example, the direction of movement of the first opening 3a relative to the fixed frame 4, during the first movement stage, is illustrated by arrow F1. figures 5 to 7 .

[0370] Here, the first step of moving the first opening 3a relative to the fixed frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

[0371] When the first opening 3a is in the closed position relative to the fixed frame 4, the drive arm 18 is disposed inside a recess 37 of the first locking device 20, as illustrated in the figure 5 .

[0372] Advantageously, the recess 37 of the first locking device 20 is defined at one 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 to its second end.

[0373] During the movement of the first opening 3a relative to the fixed 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 bears against the cam 32.

[0374] 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 aforementioned support stop, between the cam 32 and the movable arm 23.

[0375] Thus, the cam 32 is immobile, 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.

[0376] 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 .

[0377] Here, the rotational movement R1 of the mobile arm 23 relative to the assembly element 25 is implemented against the force of the first elastic return element disposed at the level of the first axis of rotation Y1.

[0378] When the shuttle 45 is positioned beyond the first locking device 20 along the sliding direction D of the first opening 3a relative to the fixed frame 4, the movable arm 23 is moved into its rest position relative to the assembly element 25 and, more specifically, relative to the cross member 47 by a rotational movement R3 around the first axis of rotation Y1, as illustrated in the figure 8 .

[0379] Following the first movement step, the process includes a second movement step of the first opening 3a relative to the fixed frame 4 from the open position to the locked half-open position of the first opening 3a relative to the fixed frame 4.

[0380] Here, the locked half-open position of the first opening 3a relative to the fixed frame 4 corresponds to the position where the drive arm 18 is positioned inside the recess 37 of the first locking device 20.

[0381] Furthermore, a locked, partially open position, referred to as the maximum position, of the first opening 3a relative to the fixed frame 4 corresponds to the contact of the drive arm 18 against the stop 31 of the movable arm 23, as illustrated in the Figure 10 .

[0382] In this example, the direction of movement of the first opening 3a relative to the fixed frame 4, during the second movement stage, is illustrated by arrow F2. figures 9 to 10 .

[0383] Here, the second stage of movement of the first opening 3a relative to the fixed frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

[0384] Thus, the support of the drive arm 18 against the stop 31 of the mobile arm 23 makes it possible to prevent the movement of the first opening 3a relative to the fixed frame 4 towards an open position of the first opening 3a relative to the fixed frame 4.

[0385] During the movement of the first opening 3a relative to the fixed frame 4 from the open position to the locked half-open position of the first opening 3a relative to the fixed frame 4, the shuttle 45 is moved by means of the flexible element 9.

[0386] During this movement of the first sash 3a relative to the fixed frame 4, from the open position to the locked, partially open position, the movable arm 23, in particular the free end 23a of the movable arm 23, is moved relative to the assembly element 25 and, more specifically, relative to the transom 47, in other words, relative to a fixed part of the window 2, initially by a first rotational movement R1 around the first axis of rotation Y1, as illustrated in the figure 9 , and, secondly, by a second rotational movement R3 around the first axis of rotation Y1, as illustrated in the Figure 10 The first rotational movement R1 around the first axis of rotation Y1 of the mobile arm 23 is opposite to the second rotational movement R3 around the first axis of rotation Y1 of the mobile arm 23.

[0387] 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 located at the first axis of rotation Y1. Furthermore, 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 located at the first axis of rotation Y1.

[0388] 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 specifically, relative to the cross member 47 by the second rotational movement R3 around the first axis of rotation Y1, as illustrated in the Figure 10 .

[0389] Furthermore, during this movement of the first sash 3a relative to the fixed frame 4 from the open position to the locked half-open position of the first sash 3a relative to the fixed frame 4, the cam 32 is moved relative to the movable arm 23 by a rotational movement R2 around the second axis of rotation Y2, as illustrated in the figure 9 .

[0390] Thus, the cam 32 is mobile in rotation around 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 half-open position of the first opening 3a relative to the fixed frame 4.

[0391] 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 level of the second axis of rotation Y2.

[0392] When the first opening 3a is in the locked half-open position relative to the fixed frame 4, the drive arm 18 is blocked in translation by the stop 31 of the movable arm 23, during a movement of the first opening 3a relative to the fixed frame 4 implemented from the maximum locked half-open position to an open position.

[0393] In one embodiment, the second movement step may include a first sub-step of moving the first opening 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, and 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 inside the recess 37 of the first locking device 20 to the maximum locked half-open position of the first opening 3a relative to the fixed frame 4.

[0394] In this embodiment, the direction of movement of the first opening 3a relative to the fixed frame 4, during the first additional movement step, corresponds to that of arrow F2. Furthermore, the direction of movement of the first opening 3a relative to the fixed frame 4, during the second additional movement step, corresponds to that of arrow F1.

[0395] Alternatively, the second movement step only includes the movement of the first opening 3a relative to the fixed frame 4 from the open position to the locked half-open position of the first opening 3a relative to the fixed frame 4.

[0396] Following the second movement step, the process includes a step of stopping the first opening 3a relative to the fixed frame 4 in the locked half-open position of the first opening 3a relative to the fixed frame 4, as illustrated in the Figure 10 or to the figure 11 .

[0397] Here, the stopping step of the first opening 3a relative to the fixed frame 4 is implemented by the electrical deactivation of the electromechanical actuator 6.

[0398] Advantageously, the control process steps 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 half-open position of the first opening 3a relative to the fixed frame 4.

[0399] Advantageously, following the attainment of the locked half-open position of the first opening 3a relative to the fixed frame 4, the process includes a second control step, so as to deactivate the first locking device 20.

[0400] Here, the second control step is implemented by issuing a control order to the electronic control unit 10 of the motorized drive device 5, in particular by means of one of the local control units 12 or central control units 13 or even a sensor.

[0401] The second ordering step can therefore be implemented manually, in particular by the user, or automatically.

[0402] Following the second ordering step, the process includes a third step of moving the first opening 3a relative to the fixed frame 4 from the locked half-open position to the locked closed position.

[0403] In this example, the direction of movement of the first opening 3a relative to the fixed frame 4, during the third movement stage, is illustrated by arrow F2. Figures 11 and 12 .

[0404] Here, the third stage of movement of the first opening 3a relative to the fixed frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

[0405] During the movement of the first opening 3a relative to the fixed frame 4 from the locked half-open position to the locked closed position, the drive arm 18 is driven in movement by means of the shuttle 45 and the flexible element 9.

[0406] 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 the figure 5 .

[0407] 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 locked closed position of the first opening 3a relative to the fixed frame 4.

[0408] Positioning the shuttle 45 relative to the first locking device 20 allows the cam 32 to be released from 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.

[0409] Here, the displacement 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 locked closed position of the first opening 3a relative to the fixed frame 4.

[0410] 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, i.e. in a position different from the rest position of the cam 32, the first locking device 20 is configured to hold the first sash 3a in a locked half-open position relative to the fixed frame 4, i.e. the first locking device 20 is configured to prevent manual opening of the first sash 3a relative to the fixed frame 4, in other words the drive arm 18 is held inside the recess 37 of the first locking device 20 by the stop 31 of the movable arm 23.

[0411] Furthermore, when the first opening 3a reaches the closed position relative to the fixed frame 4 by means of the motorized drive device 5, the control device 22 housed in the drive arm 18 activates the second locking device 21, in particular by tilting the drive element 30 inside the drive arm 18, so as to unlock the second locking device 21.

[0412] In this way, the first opening 3a is unlocked relative to the fixed frame 4.

[0413] Following the unlocking of the second locking device 21, the first opening 3a returns to its initial position relative to the fixed frame 4, as does the movable arm 23 relative to the assembly element 25 and, more particularly, to the cross member 47, as well as the cam 32 relative to the movable arm 23, as prior to the first movement stage.

[0414] Advantageously, when the first opening 3a is in the locked closed position relative to the fixed 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 the shuttle 45.

[0415] During a new execution of the first command step and the first movement step, the operation of the first locking device 20 and the motorized drive device 5 described previously is implemented in the same way.

[0416] Preferably, following the attainment of the locked half-open position of the first opening 3a relative to the fixed frame 4, the process includes a step of monitoring the position of the first opening 3a relative to the fixed frame 4.

[0417] Thus, the monitoring stage makes it possible to detect a movement of the first opening 3a relative to the fixed frame 4.

[0418] 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.

[0419] In the embodiment example, when the first opening 3a is moved relative to the fixed 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.

[0420] Thus, the displacement of the first opening 3a relative to the fixed frame 4 is determined by the position detection sensor of the output shaft of the electric motor 7.

[0421] Here, the output shaft position detection sensor of electric motor 7 is a Hall effect sensor.

[0422] Alternatively, the monitoring step is implemented by at least one position detection sensor of an output shaft of the electromechanical actuator 6.

[0423] Alternatively, the monitoring step is implemented by at least one position detection sensor of the first opening 3a relative to the fixed frame 4.

[0424] The type and number of position detection sensors are not limited and can vary. They may include, in particular, one or more optical sensors.

[0425] Here, the monitoring stage is implemented through the electronic control unit 10 of the motorized drive device 5.

[0426] Preferably, following the detection of a movement of the first opening 3a relative to the fixed frame 4 during the monitoring step, the process includes a step of determining an attempted intrusion.

[0427] Advantageously, in the case where a command order is issued from one of the control units 12, 13 or from a sensor, the step of determining an attempted intrusion is inhibited.

[0428] Thus, the movement of the first opening 3a relative to the fixed frame 4 detected during the monitoring stage is considered as a movement implemented voluntarily by a user.

[0429] In this way, the monitoring step makes it possible to determine whether the movement of the first opening 3a relative to the fixed frame 4 is implemented manually.

[0430] Advantageously, an attempted intrusion is determined in the case where the length of the displacement of the first opening 3a relative to the fixed frame 4 is greater than a predetermined threshold value M during a predetermined time period T.

[0431] Thus, such parameters M, T for the characterization of the displacement of the first opening 3a relative to the fixed frame 4 detected makes it possible to avoid prematurely determining an attempted intrusion.

[0432] By way of non-limiting example, an attempted intrusion is determined in the case where the length of the displacement of the first opening 3a relative to the fixed frame 4 is greater than one centimeter during a period of time of one minute.

[0433] Here, the step of determining an attempted intrusion is implemented through the electronic control unit 10 of the motorized drive device 5.

[0434] Advantageously, in the case where an attempted intrusion has been determined during the step of determining an attempted intrusion, the method includes a fourth step of moving the first opening 3a relative to the fixed frame 4 from the locked half-open position to the locked closed position.

[0435] In this example of implementation, the direction of movement of the first opening 3a relative to the fixed frame 4, during the fourth movement stage, corresponds to that of arrow F2.

[0436] Here, the fourth stage of movement of the first opening 3a relative to the fixed frame 4 is implemented by the electrical activation of the electromechanical actuator 6.

[0437] This fourth movement stage is implemented in a similar way to the third movement stage.

[0438] Advantageously, the fourth stage of the control process 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 fixed frame 4 in the closed position, itself locked by the second locking device 21.

[0439] Thus, window 2 and, more specifically, the building is protected against attempted intrusion by closing the first opening 3a relative to the fixed frame 4 by means of the motorized drive device 5

[0440] Prior to the fourth movement step, the process includes a step of waking up the electromechanical actuator 6 from a standby state.

[0441] Advantageously, in the case where an intrusion attempt has been determined during the intrusion attempt determination step, the process may also include a step of transmitting information to an alarm system, not shown.

[0442] Thus, the alarm system can trigger a siren to emit an audible signal, send a notification to at least one mobile device, such as a smartphone, to inform one or more users, and / or send a notification to the central control unit to command the closure of the screen of each blinding device, such as each shutter.

[0443] Thanks to the present invention, the first locking device makes it possible to lock the opening relative to the fixed frame in the locked half-open position by means of the motorized drive device.

[0444] In this way, the first locking device makes it possible to guarantee the ventilation of the building in a secure manner by a slight opening of the opening relative to the fixed frame, in particular by means of simple parts.

[0445] In addition, the unlocking of the opening relative to the fixed frame in connection with the first locking device is implemented by means of the motorized drive device configured to generate a movement of the opening relative to the fixed frame passing through the closed and locked position of the opening relative to the fixed frame by means of the second locking device.

[0446] In this way, the unlocking of the opening relative to the fixed frame is implemented solely by means of the motorized drive device.

[0447] Furthermore, the electronic control unit of the motorized drive device allows the movement of the opening relative to the fixed frame to lock the opening relative to the fixed frame in the locked half-open position and to unlock the opening relative to the fixed frame from the locked half-open position.

[0448] The first locking device thus makes it possible to prevent, or at least delay, an attempt at intrusion by an individual.

[0449] Numerous modifications can be made to the embodiment examples described above without departing from the scope of the invention as defined by the claims.

[0450] In particular, the motorized drive device 5 can be configured to move several openings 3a, 3b by means of the flexible element 9, in the same direction of movement or in opposite directions of movement.

[0451] Alternatively, the electric motor 7 of the electromechanical actuator 6 can be of the asynchronous or direct current type.

[0452] Furthermore, the envisaged embodiments and variants can be combined to generate new embodiments of the invention, without departing from the scope of the invention as defined by the claims.
