Description

The present invention relates to a motorized drive device for a sliding window, so as to move an opening relative to a fixed frame in a sliding movement, a sliding window for a building comprising such a motorized drive device, as well as 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 an opening leaf in motion relative to a fixed 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 comprises an electromechanical actuator.

We already know the document WO 2018/134008 A1 which describes a motorized drive device for a sliding window. This motorized drive device comprises an electromechanical actuator, a flexible element, a drive arm and a shuttle. The electromechanical actuator includes an electric motor. The drive arm is configured to be connected, on the one hand, to a frame of a window sash and, on the other hand, to the flexible element. The drive arm and the flexible member are configured to drive the sash relative to a frame of the window when the electromechanical actuator is electrically activated. The shuttle is attached to the flexible element. The drive arm is connected to the flexible element by means of the shuttle.

However, this motorized drive device has the drawback of directly fixing the shuttle on the flexible element by means of fixing screws. Each mounting screw is configured to thread into a shuttle screw hole. Further, these fixing screws are configured to hold the flexible member relative to the shuttle by wedging the flexible member, in particular a strand of the flexible member, between the head of each screw and a surface of the shuttle. .

Thus, such fixing of the flexible element relative to the shuttle can cause sliding of the flexible element relative to the shuttle.

In this way, such fixing of the flexible element relative to the shuttle can cause wear of the flexible element, or even rupture of the flexible element, due, in particular, to the sliding of the flexible element relative to shuttle.

In addition, such fixing of the flexible element relative to the shuttle requires controlling a tightening force of each fixing screw.

In the event of insufficient tightening or loosening of at least one of the fixing screws relative to the shuttle, a reference position of the shuttle relative to the flexible element stored by an electronic control unit of the device. motorized drive can be shifted. Consequently, the end-of-travel positions, on opening and closing of the leaf relative to the fixed frame, memorized by the electronic control unit of the motorized drive device are shifted.

We also know the document US 5,213,182 A which describes a motorized drive device for an elevator door comprising an electric motor, a belt and a shuttle. The shuttle is attached to the belt. The shuttle comprises a first part formed by a belt portion, a second part forming a fixing support and a third part forming a cover. The first part includes teeth. The second part has a groove. The teeth of the first part are inserted into the groove of the second part and, more particularly, into teeth of the belt, in an assembled configuration of the shuttle. In addition, the belt is immobilized between the teeth of the first part and the groove of the second part, following the insertion of the teeth of the first part into the groove of the second part and, more particularly, into the teeth of the second part. belt.

We also know the document EP 0 828 091 A1 which describes a motorized drive device for a door comprising a belt and a shuttle. The shuttle is attached to the belt. The shuttle includes a first room and a second room. The first part includes an assembly tab. The second piece has a slit. The assembly tab of the first part is inserted into the slot of the second part, in an assembled configuration of the shuttle. In addition, the belt is held by clamping between the first part and the second part and by inserting teeth of the belt through notches made in the second part.

The object of the present invention is to resolve the aforementioned drawbacks and to propose a motorized drive device for a sliding window, so as to move an opening relative to a fixed frame following a sliding movement, a sliding window for a building comprising such a motorized drive device, as well as a home automation installation comprising such a sliding window, making it possible to prevent a sliding of a flexible element with respect to a shuttle and wear of the flexible element, or even a rupture of the flexible element, while minimizing the costs of obtaining the motorized drive device.

It can be made from a synthetic material, such as for example nylon or polyethylene of very high molecular weight.

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

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

Advantageously, the flexible element 9 is configured to be connected, in other words is connected, to the drive arm 18, whatever the state of the locking elements of the fitting system 20, that is to say as well in the locked state than in the unlocked state of the first sash 3a with respect to the fixed frame 4.

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

In this way, the connection between the flexible element 9 and the drive arm 18 is simplified and minimizes the costs of obtaining window 2.

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

Thus, the drive arm 18 is configured to hook onto the flexible element 9 arranged above the fixed frame 4, in particular the upper cross member 4a of the fixed frame 4.

In addition, the drive arm 18 and the first locking device 21 are arranged closest to the flexible element 9, since the flexible element 9 extends along the upper cross member 4a of the fixed frame 4.

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, in the assembled configuration of the motorized drive device 5 on the window 2.

Thus, the drive arm 18 is fixed to a face of the first lateral upright 15c of the frame 15 of the first opening 3a oriented towards the outside of the window 2, in other words visible to the user.

In this way, the fixing of the drive arm 18 on the first lateral upright 15c of the frame 15 of the first leaf 3a is facilitated compared to fixing the drive arm 18 on an internal zone of the frame 15 of the first leaf 3a, in particular located at the level of the first sliding rail 11a of the upper cross member 4a of the fixed frame 4, in the assembled configuration of the window 2 with respect to the building.
