Description

TECHNICAL FIELD OF THE INVENTION

The present invention is in the field of building joinery. More particularly, the invention relates to a motorized leaf system.

STATE OF THE ART

In some areas, the majority of building windows are fitted with hinged shutters, usually located in the doorway outside the window, which must be opened and closed by hand morning and evening. To save time, many owners would like to have electric shutters with motorized opening and closing. The simplest and cheapest solution generally considered in this case is the dismantling of manual swing shutters, and their replacement by electric shutters. But due to aesthetic considerations or because of town planning regulations in force in certain towns, it is sometimes desirable to keep traditional swinging shutters, often made of wood.

To motorize these shutters, it has been proposed in the prior art to dig one or more niches in the jamb or the window frame. Electric motors are installed in these niches, which are then built. Holes are drilled in the wall to allow the electrical cables to power these motors to pass. These electric motors are connected to the swinging shutters by articulated arms, or rods.

The device for actuating swing shutters proposed by the prior art has many drawbacks. First of all, it is not very aesthetic, certain mechanical parts being visible. In addition, its installation requires structural work, including the digging of niches in the jamb or the window frame, which increases the cost of installation. Finally, certain mechanical components being located in the open air, they are subject to bad weather and their lifespan is therefore limited.

The present invention aims to remedy the drawbacks of the prior art for the motorization of swing shutters, by proposing a motorized swing system which is easy to install, inexpensive, discreet from an aesthetic point of view and protected from the weather.

OBJECT OF THE INVENTION

To this end, the invention relates firstly to a leaf system configured to be installed in a bay. The leaf system comprises a frame and at least one opening, called a leaf. The leaf system comprises at least one motor driving in rotation at least one mechanical reduction device. The engine is included in the frame. The reduction device rotates a hinge. The hinge is rigidly linked to the leaf, so that the rotation of the hinge causes the leaf to rotate relative to the frame. The axis of rotation of the hinge coincides with the axis of rotation of the leaf relative to the frame, called the X axis.

By bay is meant an opening of which at least one of the sides comprises a fixed masonry element. A bay can be an opening made in a wall, a passage between two pillars, or other.

By frame is meant all the parts of the wing system which are fixed relative to the opening.

By leaf means a leaf of any kind (window, door, shutter, mesh, gate, or other) being movable in rotation relative to the frame.

By motor is meant a member capable of generating a rotational movement and of transmitting it to an axis.

By reduction device is meant a mechanical device comprising an input axis and an output axis, the device being configured to modify the speed of rotation and / or the torque between its input axis and its output axis.

By hinge is meant a part serving to support the leaf and transmitting a rotational movement to the leaf.

The flap system according to the invention has the advantage of being robust, aesthetic and compact. Indeed, the rotational movement being transmitted to the leaf via a hinge located in the axis X of rotation of the leaf, no mechanism is located in the open air. In particular, the leaf system according to the invention has no articulated arm. The appearance of the motorized leaf system according to the invention is almost identical to that of a non-motorized leaf mounted on hinges or hinges.

According to particular embodiments, the invention also meets the following characteristics, implemented separately or in each of their technically operating combinations.

In a particular advantageous embodiment, the frame has at least one upright inside which the engine is located.

By upright is meant a part of the frame extending vertically.

The engine located inside an upright is well protected from the weather and invisible to the user.

In a particular embodiment, the frame, said frame, has two uprights and a crosspiece.

By cross member means a part of the frame extending horizontally.

Installing a frame within a bay is a common and inexpensive process for those skilled in the art.

In one embodiment, the motor rotates two distinct reduction devices, each of the reduction devices rotating a hinge, each of the hinges being rigidly connected to the leaf, so that the rotation of the hinges causes the leaf to rotate relatively in the frame, the axis of rotation of each hinge being coincident with the X axis.

It is common for a non-motorized leaf to be held by two connecting elements (hinges, hinges, hinges or others). In the case of the leaf system according to the invention, the leaf can be linked to two collinear hinges which cause it to rotate. These hinges are themselves driven in rotation by a single motor in the case where the torque supplied by this motor is sufficient.

In one embodiment, the leaf system comprises two separate motors, each of the motors driving a reduction device in rotation, each of the reduction devices driving a hinge in rotation, each of the hinges being rigidly connected to the leaf, so that the rotation of the hinges rotates the leaf relative to the frame, the axis of rotation of each of the hinges being coincident with the axis X.

For certain heavy leaves or those with significant inertia, two motors are located in the frame, these motors driving the leaf in rotation via two distinct collinear hinges. The torque thus provided is sufficient to cause the leaf to rotate relative to the frame.

In one embodiment, the reduction device comprises a double wheel and worm reducer.

The double wheel and worm gear reducer can be configured to decrease the speed of rotation and increase the torque between the motor and the hinge linked to the leaf, this advantageously making it possible to have a small motor and small power in the of the wing system.

In one embodiment, the motor is an electric motor.

An electric powered motor is particularly suitable for the case of a leaf system installed in a building bay.

In one embodiment, the motor is powered by a solar panel.

The power supply of the motor by a solar panel advantageously allows its autonomy, this avoiding having to connect the leaf system to the domestic electrical network. The installation of the wing system is therefore simpler and faster, and the electrical risks for the user of the wing system are reduced.

In one embodiment, the leaf is a shutter.

By shutter is meant a movable leaf capable of obscuring the light passing through the bay of a window.

The wing system according to the invention is particularly well suited for motorized wing shutters.

In one embodiment, the leaf system is remotely controlled by radio waves.

Being able to remotely control the movements of the leaf advantageously increases the comfort and simplicity of use of the leaf system.

In one embodiment, the leaf system includes an alarm module configured to trigger a signal in the event of rotation of the leaf relative to the frame forced into the house.

According to another aspect, the invention relates to a method of installation in a bay of a leaf system according to one of the above embodiments, comprising in particular steps of:

- 51 / fixing the frame in the bay,

- 52 / connection of the leaf with the hinge (s).

The motor located in the frame guarantees the ease of installation of the leaf system: no structural work or masonry is necessary to set up the leaf system in a bay. Installation of the casement system is easy and inexpensive, especially since there is no need to dig a recess in the jamb or window frame to place the motor in it.

According to another aspect, the invention relates to a method of installing a leaf system according to one of the embodiments above, in a bay which comprises a leaf integral with a hinge movable in rotation around a rod fixed to a frame of the bay, comprising in particular steps of:

- 61 / disassembly of the leaf hinge with the rod,

- 62 / separation of the rod from the frame of the bay,

- 63 / fixing the frame in the bay,

- 64 / connection of the leaf with the hinge (s).

Installing the leaf system to motorize an existing leaf already in a bay is particularly easy and efficient. The leaf, if it has a hinge, can advantageously be kept as it is and mounted on the frame of the leaf system. Few operations are necessary, and none of them require very advanced tools or know-how. The leaf system according to the invention thus makes it possible to carry out the motorization of an existing manual opening leaf at a lower cost.
