Description

Sliding window for a building and home automation installation comprising such a sliding window

The present invention relates to a sliding window for a building comprising a motorized drive device for moving a sash relative to a sleeping frame in a sliding movement.

The present invention also relates to a home automation installation comprising such a sliding window.

In general, the present invention relates to the field of windows comprising a motorized drive device setting in motion an opening leaf with respect to a sleeping frame in a sliding movement, between at least a first position and at least a second position.

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

Sliding windows are already known for a building comprising a sleeping frame, an opening, a motorized drive device for sliding movement of the opening relative to the sleeping frame, a trunk and a stop. The motorized drive device includes an electromechanical actuator and a drive arm. The electromechanical actuator includes an electric motor. The drive arm is configured to drive the sash in displacement relative to the frame, when the electromechanical actuator is electrically activated. The trunk is configured to house at least the electromechanical actuator. The stopper is configured to define an open end-of-travel position of the sash relative to the frame.

However, these sliding windows have the disadvantage of fixing the stop to a frame of the opening. The area of attachment of the stop relative to the frame of the door is located in the lower part of the frame of the door.

The open end-of-travel position of the sash with respect to the sash frame corresponds to the abutment of the stop fixed to the sash frame against a frame of another sash, in particular in the case of a window comprising a plurality of openings, or against the sleeping frame, in particular in the case of a window known as “brick partition”.

Thus, the positioning of the stop in the lower part of the frame of the opening does not prevent a tilting movement of the opening relative to the fixed frame, when reaching the open end of travel position of the opening with respect to the sleeping frame.

The tilting movement of the opening relative to the sleeping frame is due to the tensile force generated by the motorized drive device, arranged in the case of the sliding windows known in the upper part thereof, and by the force exerted by the stop on the lower part of the opening, when reaching the open end of travel position of the opening relative to the frame.

This tilting movement of the opening relative to the sleeping frame is caused by the misalignment of the tensile force generated by the motorized drive device and the force exerted by the stop.

In addition, the fixing of the stopper at the sash frame requires a drilling operation of the sash frame and assembly of the stopper with the sash frame by the window manufacturer.

Therefore, fixing the stopper at the sash frame requires adaptation to each window model and increases the cost of obtaining windows.

Furthermore, the fixing of the stopper at the level of the opening frame harms the aesthetics of the windows.

The present invention aims to solve the aforementioned drawbacks and to provide a sliding window for a building comprising a motorized drive device for moving a leaf relative to a sleeping frame in a sliding movement and a stop configured to define a position limit switch open of the opening relative to the sleeping frame, as well as a home automation installation comprising such a sliding window, making it possible to avoid a tilting movement of the opening relative to the sleeping frame, upon reaching from the open end-of-travel position of the opening relative to the frame, while minimizing the costs of obtaining the window and improving the aesthetic appearance of the window.

In this way, such a positioning of the stop inside the trunk makes it possible to improve the alignment of the tensile force generated by the motorized drive device and of the force exerted by the stop, so as to avoid a tilting movement of the sash relative to the frame.

In addition, the stopper is integrated in the trunk configured to receive at least part of the motorized drive device, including the electromechanical actuator.

Furthermore, the positioning and fixing of the stop is independent of the window and, more particularly, of the frame and the opening, therefore of the manufacturer of these elements of the window. The motorized drive and the trunk can thus be compatible with different models of sliding window.

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

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

Thus, the use of a flexible element 9 made of synthetic material makes it possible to minimize the diameter of the pulleys of the motorized drive device 5.

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

The motorized drive device 5 also comprises a drive arm 18 illustrated in FIGS. 1 to 6. The drive arm 18 is configured to drive the first opening 3a in displacement relative to the frame 4, when the electromechanical actuator 6 is electrically activated.

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

Advantageously, the flexible element 9 is connected to the drive arm 18, whatever the state of the locking elements of the fitting system 20, that is to say both in the locked state and in the unlocked state of the first leaf 3a relative to the sleeping frame 4.

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

In addition, when the first opening 3a is moved relative to the sleeping frame 4 in a second sliding direction, in particular when moving from an open position to the closed position of the first opening 3a relative to the sleeping frame 4, the first strand 9a of the flexible element 9 takes place 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.

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

In this way, the direction of rotation of the first strand 9a of the flexible element 9 around the first part of the winding pulley 19 is opposite to the direction of rotation of the second strand 9b of the element flexible 9 around the second part of the winding pulley 19.

Advantageously, the direction of sliding of the first opening 3a relative to the sleeping frame 4 is determined as a function of the direction of rotation of the output shaft 8 of the electromechanical actuator 6. In addition, the direction of driving in rotation of the winding pulley 19 is determined by the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

Thus, the direction of rotation of the first strand 9a and of the second strand 9b of the flexible element 9 around the first and second parts of the winding pulley 19 is a function of the direction of rotation of the output shaft 8 of the electromechanical actuator 6.

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

In addition, the second strand 9b of the flexible element 9 comprises a second end connected to the locking control device 26 In addition, the second end of the first strand 9a of the flexible element 9 is opposite the first end of the first strand 9a of the flexible element 9 connected to the first part of the winding pulley 19. In addition, the second end of the second strand 9b of the flexible element 9 is opposite the first end of the second strand 9b of the flexible element 9 connected to the second part of the winding pulley 19.

Thus, the flexible element 9 is made in two parts. The first part of the flexible element 9 is formed by the first strand 9a extending between the first part of the winding pulley 19 and the locking control device 26. In addition, the second part of the flexible element 9 is formed by the second strand 9b extending between the second part of the winding pulley 19 and the locking control device 26.

Advantageously, the anti-false operation system 27 comprises a retractable pin 34. The retractable pin 34 is configured to be moved between a rest position, in which the cremone bolt is blocked, and an activated position, in which the cremone bolt is released. In addition, the anti-false operation system 27 is activated when the retractable pin 34 is inserted into a housing, not shown, formed in the frame 15 of the first opening 3a.

In practice, the retraction of the retractable pin 34 into the abovementioned housing is implemented by the abutment of the retractable pin 34 against the sleeping frame 4, in particular the first lateral upright 4c of the sleeping frame 4, that is to say -display when the first opening 3a is in the closed position relative to the sleeping frame 4.

Thus, the stop 39 makes it possible to absorb a shock with the drive arm 18, when reaching the open end-of-travel position of the first leaf 3a relative to the sleeping frame 4.

Here, the stop 39 is disposed in the upper part of the window 2, so as to avoid a tilting movement of the first leaf 3a relative to the frame 4, when reaching the open end position of the first leaf 3a relative to the sleeping frame 4.

Consequently, keeping the first opening 3a in position relative to the sleeping frame 4, when reaching the open end-of-travel position of the first opening 3a relative to the sleeping frame 4, makes it possible to avoid displacement, in particular a lifting and an offset, of the sliding elements of the window 2 relative to the first and second sliding rails 11a, 11b of the lower cross member 4b.

In addition, such a tilting movement is particularly avoided when the motorized drive device 5 learns the open end-of-travel position of the first leaf 3a relative to the frame 4.

Furthermore, such a tilting movement can be avoided when the ratio of the dimensions of the first leaf 3a, as well as the weight of the first leaf 3a, are specific, in particular less than threshold values determined as a function of the tensile force exerted. by the motorized drive device 5 on the first opening 3a.

In an exemplary embodiment, the mounting wall 29 of the trunk 30 comprises a housing, not shown. In addition, the housing is configured to receive part of the stop 39.

Thus, the housing formed in the mounting wall 29 of the trunk 30 makes it possible to simplify the positioning of the stop 39 relative to the mounting wall 29 of the trunk 30 and to guarantee better resistance to tearing of the stop 39 relative to the mounting wall 29 of the trunk 30.

Thanks to the present invention, the fixing of the stop inside the trunk makes it possible to avoid a tilting movement of the opening with respect to the fixed frame, when reaching the open end-of-travel position of opening it relative to the sleeping frame, while minimizing the costs of obtaining the window and improving the aesthetic appearance of the window.

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

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

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

In addition, the embodiments and variants envisaged can be combined to generate new embodiments of the invention.
