Thus, the stop 61 of the movable arm 53 ensures that the first opening 3a is held in position with respect to the fixed frame 4 in the half-open locked position.

In this way, the stop 61 of the movable arm 53 makes it possible to block the drive arm 18 and therefore to guarantee a locking in the locked ajar position, where the resting of the drive arm 18 against the stop 61 of the movable arm 53 corresponds to the maximum opening of the first sash 3a with respect to the fixed frame 4.

Preferably, the drive arm 18, in particular a wall 18c of the drive arm 18, is configured to cooperate with a free end 53a of the movable arm 53, 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 sash 3a with respect to the fixed frame 4.

Thus, the drive arm 18 ensures that it is kept in contact with the free end 53a of the movable arm 53, during a movement of the first opening 3a relative to the fixed frame 4, in the direction of movement from d 'an open position towards the closed position of the first opening 3a relative to the fixed frame 4.

Advantageously, the first locking device 22 comprises a second elastic return element 54 disposed between the movable arm 53 and the cam 62.

Thus, the second elastic return element 54 ensures that the cam 62 is held in a rest position relative to the movable arm 53.

Here, the second elastic return element 54 is a spring, in particular of the pin type.

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

Advantageously, the second elastic return element 54 is located on the same axis of rotation Z2 as that of the cam 62.

In such a case, the cam 62 bears against a support stop, not shown, of the movable arm 53.

Advantageously, the ramp 60 of the shuttle 45 is configured to cooperate with the cam 62, during a movement of the first opening 3a relative to the fixed frame 4, both in the direction of movement from an open position towards the closed position of the first leaf 3a with respect to the fixed frame 4, only in the direction of movement from the closed position towards an open position of the first leaf 3a with respect to the fixed frame 4.

Thus, the ramp 60 of the shuttle 45 makes it possible to ensure that it is kept in contact with the cam 62 of the release device 59, during a movement of the first leaf 3a relative to the fixed frame 4, regardless of the direction of movement of the first sash 3a in relation to the fixed frame 4.

Here, the ramp 60 is integrated with the shuttle 45.

In addition, the ramp 60 of the shuttle 45 makes it possible to prevent the drive arm 18 from coming into contact with the movable arm 53 of the first unlocking device 22, when unlocking the first locking device 22.

Following the locking of the first leaf 3a relative to the fixed frame 4 in the closed position by means of the second locking device 21, then during a movement of the first leaf 3a relative to the fixed frame 4 following the direction of movement from the closed position towards an open position of the first opening 3a relative to the fixed frame 4, the shuttle 45, in particular the ramp 60 of the shuttle 45, is brought into contact with the cam 62.

Thus, the movement of the shuttle 45 by means of the motorized drive device 5 makes it possible to push back the movable arm 53, against the force exerted by the second elastic return element 54, so as to release the stop 61 from the movable arm 53 relative to the drive arm 18.

In this way, the first locking device 22 is unlocked and the first opening 3a can be moved relative to the fixed frame 4 to an open position located beyond the locked ajar position, by means of the motorized drive device 5.

Advantageously, when the first opening 3a is in the closed position not locked with respect to the fixed frame 4, the release device 59 and, more particularly, the cam 62 of the release device 59 is in contact with the shuttle 45 and, more particularly , with the ramp 60 of the shuttle 45.

Advantageously, when passing from the unlocked closed position of the first leaf 3a relative to the fixed frame 4 to the locked closed position of the first leaf 3a relative to the fixed frame 4, by means of the second locking device 21, the device of motorized drive 5 drives the first leaf 3a relative to the fixed frame 4 following a translational movement, as illustrated by an arrow F1, parallel to the sliding direction D, in particular on the figures 5 and 6 .

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

Advantageously, when the first opening 3a is in the locked closed position relative to the fixed frame 4, the release device 59 and, more particularly, the cam 62 of the release device 59 is no longer in contact with the shuttle 45 and, more particularly, with the ramp 60 of the shuttle 45.

Thus, when reaching the locked closed position of the first opening 3a relative to the fixed frame 4, the release device 59 is activated, in other words returned to a rest position, in particular by means of the second elastic return element 54.

In addition, the locking of the first leaf 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, of the shuttle 45 and of the control device 26, as described above.

We will now describe, with reference to figure 7 , an embodiment of a method of operating the motorized drive device 5 of the sliding window 2 illustrated in figures 1 to 6 .

The method comprises a step of first displacement E10 of the first leaf 3a relative to the fixed frame 4 from an open position to the locked ajar position of the first leaf 3a relative to the fixed frame 4, implemented manually, without electrically activate the electric motor 7 of the electromechanical actuator 6.

Thus, the first displacement step E10 is implemented manually by the user, in particular by exerting a pressure, in other words a thrust, on the first opening 3a relative to the fixed frame 4.

Here, the locked ajar position corresponds to the position where the drive arm 18 is positioned within a recess 65 of the first locking device 22.

In this exemplary embodiment, the direction of movement of the first leaf 3a relative to the fixed frame 4, during the first movement step E10, is illustrated by the arrow F1 at the figures 5 and 6 .

Advantageously, bringing the drive arm 18 to bear against the stop 61 of the movable arm 23 makes it possible to prevent the movement of the first leaf 3a relative to the fixed frame 4 towards an open position of the first leaf 3a relative to the fixed frame 4 .

During the movement of the first sash 3a relative to the fixed frame 4 to From the open position to the locked ajar position, during the first displacement step E10, the shuttle 45 is moved by means of the flexible element 9, although the electric motor 7 of the electromechanical actuator 6 n is not electrically activated.

During this movement of the first leaf 3a relative to the fixed frame 4 from the open position to the locked ajar position, the movable arm 53, in particular the free end 53a of the movable arm 53, is moved relative to the assembly element 55 and, more particularly, relative to the mounting wall 29 of the box 30, in other words relative to a fixed part of the window 2, initially, by a first rotational movement R1 around of the first axis of rotation Z1 and, secondly, by a second rotational movement R2 about the first axis of rotation Z1. The first rotational movement R1 about the first axis of rotation Z1 of the movable arm 53 is opposed to the second rotational movement R2 about the first axis of rotation Z1 of the movable arm 53.

Here, the first rotational movement R1 of the movable arm 53 relative to the assembly element 55 is implemented against the force of the first elastic return element arranged at the level of the first axis of rotation Z1. In addition, the second rotational movement R2 around the first axis of rotation Z1 of the movable arm 53 relative to the assembly element 55 is implemented by the force exerted by the first elastic return element arranged at the level of the first axis of rotation Z1.

Thus, when the drive arm 18 is positioned inside the recess 65 of the first locking device 22, the movable arm 53 is moved into its rest position relative to the assembly element 55 and, more particularly, with respect to the mounting wall 29 of the box 30 by the second rotational movement R2 about the first axis of rotation Z1.

In addition, during this movement of the first opening 3a relative to the fixed frame 4 from the open position to the locked ajar position, the cam 62 is moved relative to the movable arm 53 by a first rotational movement R3 around of the second axis of rotation Z2.

Thus, the cam 62 is movable in rotation around the second axis of rotation Z2 during this movement of the first opening 3a relative to the fixed frame 4 from the open position to the half-open locked position.

Here, the first rotational movement R3 of the cam 62 relative to the movable arm 53 is implemented against the force of the second elastic return element 54 disposed at the level of the second axis of rotation Z2.

When the first sash 3a is in the half-open position locked by relative to the fixed frame 4, the drive arm 18 is blocked in translation by the stop 61 of the movable arm 53, during a movement of the first opening 3a relative to the fixed frame 4 implemented from the locked ajar position to an open position.

Advantageously, following the achievement of the half-open locked position of the first sash 3a relative to the fixed frame 4, during the first displacement step E10, the method further comprises a stop step E20 of the first sash 3a in relation to the fixed frame 4.

The method further comprises a step of determining E30, by means of the counting device 24, of the manual movement and of reaching the half-open locked position of the first leaf 3a relative to the fixed frame 4, this manual movement being that obtained during the first displacement step E10.

The stop step E20 makes it possible to guarantee that the position reached by the first sash 3a relative to the fixed frame 4 is a final position and linked to a real manual movement, determined during the determination step E30, and not to a vibration or a detection fault by the counting device 24, in particular due to the precision of the sensors 32.

The positioning of the first sash 3a relative to the fixed frame 4 in the half-open position locked from an open position implemented, during the first displacement step E10, without electrically activating the electric motor 7 of the electromechanical actuator 6, is considered by the electronic control unit 10 as an involuntary positioning on the part of the user of the first opening 3a relative to the fixed frame 4 and as possibly presenting a safety risk.

Such a safety risk can be proven, in particular, in the case where a user would need to move manually, without electrically activating the electromechanical actuator 6, and as quickly as possible the first opening 3a relative to the fixed frame 4 in a position open, so that you can get out of the building in an emergency, especially in the event of a fire.

Here, the manual displacement and the attainment of the locked ajar position of the first opening 3a relative to the fixed frame 4, during the first displacement step E10, is determined through the counting device 24, since the flexible element 9 is driven by the first sash 3a and, therefore, the output shaft 8 of the electromechanical actuator 6, as well as the output shaft of the electric motor 7, are rotated by the winding pulley 19 and flexible element 9.

Advantageously, the step E30 for determining the manual displacement and reaching the half-open locked position of the first sash 3a with respect to the fixed frame 4 is implemented when the electric motor 7 of the electromechanical actuator 6 is not electrically activated by means of the electronic control unit 10, in other words in the absence of an electrical activation of the electric motor 7 of the electromechanical actuator 6 by the electronic control unit 10.

Advantageously, the step of determining E30 of the manual movement and of reaching the half-open locked position of the first opening leaf 3a with respect to the fixed frame 4 is implemented by means of the electronic control unit 10 by monitoring the signal. S from the counting device 24.

Advantageously, the monitoring of the signal S coming from the counting device 24 is implemented by scanning the state of the sensors 32 of the counting device 24 according to the predetermined frequency F.

By way of non-limiting example, the predetermined frequency F for scanning the state of the sensors 32 of the counting device 24 is of the order of five hundred milliseconds.

Advantageously, the manual movement of the first leaf 3a relative to the fixed frame 4 is determined, during the determination step E30, when the first leaf 3a is moved relative to the fixed frame 4 by a distance greater than or equal to a value predetermined distance threshold L between two consecutive samples of the signal S coming from the counting device 24.

By way of non-limiting example, the predetermined distance threshold value L is of the order of one centimeter.

Advantageously, a value of the manual displacement of the first leaf 3a relative to the fixed frame 4 can be determined by the electronic control unit 10 as a function of data coming from the counting device 24 and, more particularly, as a function of a number d. 'pulses of the signal S supplied by the sensors 32 of the counting device 24 and information related to the motorized drive device 5 stored by the electronic control unit 10 and, more particularly, by the microcontroller 36, which can be, in particular , a reduction ratio of the reducer of the electromechanical actuator 6 and a winding diameter of the flexible element 9 around the winding pulley 19.

Thus, the number of pulses of the signal S supplied by the sensors 32 of the counting device 24 can be transformed into a linear displacement value of the flexible element 9 and, consequently, of the first opening 3a with respect to the fixed frame 4 .

In this way, in this exemplary embodiment, the value of the manual displacement of the first sash 3a relative to the sash frame 4 is determined as a function of a rotation of the rotor of the electric motor 7 of the electromechanical actuator 6.

The determination step E30 thus makes it possible to determine a starting point for the manual movement of the first leaf 3a relative to the fixed frame 4, during the first movement step E10.

Thus, the method makes it possible to guarantee that the manual movement of the first opening leaf 3a relative to the fixed fixed frame 4, during the determination step E30, starts in an open position outside the locked ajar position and ends in the position. half-open locked.

Advantageously, after reaching the locked ajar position, during the first displacement step E10, the method further comprises a step E60 for determining a count value, by means of the counting device 24.

Advantageously, the determination step E60 is implemented after the first displacement step E10 and, more particularly, after the stop step E20. In addition, this determination step E60 is implemented prior to the determination step E30.

Advantageously, the method further comprises a step of storing E40 of the starting point of the manual movement of the first opening 3a relative to the fixed frame 4 determined, during the determination step E30.

Advantageously, the starting point of the manual movement of the first leaf 3a relative to the fixed frame 4 determined, during the determination step E30, is stored, during the storage step E40, by the electronic control unit 10 and, more particularly, by the microcontroller 36.

Advantageously, when the first leaf 3a is held in position relative to the fixed frame 4, in other words when the first leaf 3a is moved relative to the fixed frame 4 by a distance less than the threshold value of predetermined distance L between at least two consecutive samples of the signal S coming from the counting device 24, the manual movement of the first leaf 3a relative to the fixed frame 4 is considered to be completed.

Advantageously, the attainment of the half-open locked position of the first sash 3a relative to the fixed frame 4 is determined, during the determination step E30, by counting a number of pulses of the signal S supplied by the sensors 32 of the counting device 24, in particular from a value determined and stored by the electronic control unit 10 following a last movement of the first leaf 3a relative to the fixed frame 4 implemented by the electrical activation of the 'electromechanical actuator 6 and following a learning of the end-of-travel positions, open and closed, of the first leaf 3a with respect to the fixed frame 4.

Following the determination of the manual displacement and of the attainment of the locked ajar position of the first sash 3a relative to the fixed frame 4, during the determination step E30, the method comprises an automatic starting step E50 of the electric motor 7 of the electromechanical actuator 6 by means of the electronic control unit 10, so as to unlock the first locking device 22 by moving the first leaf 3a relative to the fixed frame 4, implemented by the electrical activation of the motor electric 7 of the electromechanical actuator 6.

Thus, the method makes it possible to unlock the first leaf 3a relative to the first locking device 22, following a manual movement of the first leaf 3a relative to the fixed frame 4 in the half-open locked position.

In this way, the automatic starting step E50 of the electric motor 7 of the electromechanical actuator 6 makes it possible to deactivate the first locking device 22 and is implemented automatically by the electronic control unit 10, in particular without that a control command is issued by one of the local control units 12 or central 13, and by electrically activating the electric motor 7 of the electromechanical actuator 6.

In addition, such unlocking of the first leaf 3a relative to the first locking device 22, following a manual movement of the first leaf 3a relative to the fixed frame 4 from an open position in the locked ajar position, makes it possible to avoid a security risk, in particular in the event that a user needs to move the first opening 3a relative to the fixed frame 4 in an open position, so as to exit the building in an emergency, manually, that is to say say without electrically activating the electromechanical actuator 6, and as quickly as possible.

Furthermore, such unlocking of the first leaf 3a relative to the first locking device 22, following a manual movement of the first leaf 3a relative to the fixed frame 4 from an open position in the locked ajar position, allows a person outside the building to be able to move the first opening 3a relative to the fixed frame 4 in an open position, manually, that is to say without electrically activating the electromechanical actuator 6, so as to be able to enter building.

• deuxième déplacement E501 du premier ouvrant 3a par rapport au cadre dormant 4 à partir de la position entrebâillée verrouillée jusqu'à la position fermée, mis en œuvre par l'activation électrique du moteur électrique 7 de l'actionneur électromécanique 6, la position entrebâillée verrouillée correspondant à une position de démarrage du deuxième déplacement,
• verrouillage E502 du premier ouvrant 3a par rapport au cadre dormant 4 dans la position fermée au moyen du deuxième dispositif de verrouillage 21, mis en œuvre par l'activation électrique du moteur électrique 7 de l'actionneur électromécanique 6,
• déverrouillage E503 du premier ouvrant 3a par rapport au cadre dormant 4 dans la position fermée au moyen du deuxième dispositif de verrouillage 21, mis en œuvre par l'activation électrique du moteur électrique 7 de l'actionneur électromécanique 6, et
• troisième déplacement E504 du premier ouvrant 3a par rapport au cadre dormant 4 à partir de la position fermée jusqu'à la position de démarrage du deuxième déplacement du premier l'ouvrant 3a par rapport au cadre dormant 4, mis en œuvre par l'activation électrique du moteur électrique 7 de l'actionneur électromécanique 6.

Advantageously, the automatic start-up step E50 comprises at least the following sub-steps:

• second displacement E501 of the first leaf 3a relative to the fixed frame 4 from the half-open locked position to the closed position, implemented by the electric activation of the electric motor 7 of the electromechanical actuator 6, the half-open locked position corresponding to a starting position for the second movement,
• E502 locking of the first leaf 3a relative to the fixed frame 4 in the closed position by means of the second locking device 21, implemented by the electrical activation of the electric motor 7 of the electromechanical actuator 6,
• E503 unlocking of the first leaf 3a relative to the fixed frame 4 in the closed position by means of the second locking device 21, implemented by the electrical activation of the electric motor 7 of the electromechanical actuator 6, and
• third movement E504 of the first leaf 3a relative to the fixed frame 4 from the closed position to the starting position of the second movement of the first leaf 3a relative to the fixed frame 4, implemented by electrical activation of the electric motor 7 of the electromechanical actuator 6.

Thus, the sub-steps E501, E502, E503, E504 of the automatic start-up step E50 are implemented automatically by the electronic control unit 10, in particular without a control command being issued by one of the local control units 12 or central 13, and by electrically activating the electric motor 7 of the electromechanical actuator 6.

In this exemplary embodiment, the direction of movement of the first leaf 3a relative to the fixed frame 4, during the second movement sub-step E501, is illustrated by the arrow F1 at figures 5 and 6 . In addition, the direction of movement of the first leaf 3a relative to the fixed frame 4, during the third movement sub-step E504, is illustrated by the arrow F2 at figures 5 and 6 .

During the movement of the first leaf 3a relative to the fixed frame 4, during the second movement and third movement sub-steps E501, E504, the drive arm 18 is driven in movement by means of the shuttle 45 and the flexible element 9.

Advantageously, the deactivation of the first locking device 22 is implemented when the shuttle 45 is positioned inside the recess 65 of the first locking device 22 and, more particularly, when the cam 62 is moved to its position. rest position relative to the movable arm 53 by a second rotational movement R4 around the second axis of rotation Z2.

Thus, the deactivation of the first locking device 22 is implemented only when the shuttle 45 is in the position corresponding to the closed position. locked of the first sash 3a in relation to the fixed frame 4.

Such positioning of the shuttle 45 relative to the first locking device 22 enables the cam 62 to be released relative to the ramp 60 of the shuttle 45 and to return the cam 62 to its rest position.

Thus, the release device 59 is activated, following the locking of the first opening 3a in the closed position, by means of the second locking device 21.

The second rotational movement R4 around the second rotational axis Z2 takes place in a direction opposite to that of the first rotational movement R3 around this rotational axis.

Here, the movement of the cam 62 in its rest position relative to the movable arm 53 by the second rotational movement R4 around the second axis of rotation Z2 is configured to be implemented only when the shuttle 45 is in the corresponding position. in the locked closed position of the first sash 3a with respect to the fixed frame 4.

Advantageously, as long as the cam 62 is maintained in an inclined position by the shuttle 45, in particular by the ramp 60 of the shuttle 45, that is to say in a position different from the rest position of the cam 62, the first locking device 22 is configured to keep the first sash 3a in a locked ajar position relative to the fixed frame 4, i.e. the first locking device 22 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 retained inside the recess 65 of the first locking device 22 by the stop 61 of the movable arm 53.

In addition, when reaching the closed position of the first opening 3a relative to the fixed frame 4 by means of the motorized drive device 5, the control device 26 housed in the drive arm 18 activates the second control device. locking 21, in particular by tilting the drive element 43 inside the drive arm 18, so as to unlock the second locking device 21.

In this way, the first leaf 3a is unlocked with respect to the fixed frame 4.

Following the unlocking of the second locking device 21, the first opening 3a returns to the initial position relative to the fixed frame 4, as does the movable arm 53 relative to the assembly element 55 and, more particularly, to the wall of mounting 29 of the box 30, as well as the cam 62 relative to the movable arm 53, as before the automatic start step E50.

Here and as visible at the figure 7 , the automatic start-up step E50 is implemented following the determination step E30 and, more particularly, the storage step E40.

Deactivation of the first locking device 22 therefore cannot be implemented by manual movement of the first leaf 3a relative to the fixed frame 4 from the half-open locked position, since the cam 62 cannot be released relative to the movable arm 53, via the ramp 60 of the shuttle 45.

Advantageously, the displacement of the first opening 3a relative to the fixed frame 4, during the third displacement sub-step E504, is implemented until the determined count value is reached, during the determination step E60.

Thanks to the present invention, the method makes it possible to unlock the opening relative to the first locking device, following a manual movement of the opening relative to the fixed frame from an open position in the locked ajar position.

In this way, the step of automatically starting the electric motor of the electromechanical actuator makes it possible to deactivate the first locking device and is implemented automatically by the electronic control unit, in particular without an order of command is issued by a local or central control unit, and by electrically activating the electric motor of the electromechanical actuator.
