Description

The present invention relates to a frame for swing flap intended to be installed in an opening formed in a wall, comprising at least one hinge element on which can be rotatably mounted a flap movable between an open position and a closed position, said a chassis having an "L" section and consisting of a first frame intended to be pressed against an area of the wall bordering said opening and a second frame, perpendicular to the first, intended to extend in said opening, said first and second frames having an outer face and an inner face and each having two parallel side uprights interconnected by an upper cross member and a lower cross member.

The present invention relates to the field of the building and will find an application both in the field of new buildings as in the renovation of old buildings. In the latter case, the implementation of swing shutters with prefabricated chassis has proved particularly advantageous since these devices make it possible to overcome many structural constraints, do not require or little masonry work and are therefore very easy to install, whatever the environment, while guaranteeing a perfect thermal and luminous seal.

As for the shutters, there are currently solutions for motorizing shutters of the type comprising a prefabricated chassis, to improve their comfort of use and to avoid the tedious and time-consuming closing operation / manual opening.

Such a solution is notably known from the document FR 2,957,113 which plans to install an actuator in an inner housing formed in each of the lateral uprights of the frame, parallel to the axis of a hinge. Another similar solution, providing for integrating an actuator into the upper cross member of the chassis, specifically configured to provide a housing, is described in document WO 2008/0931189 . Such products can thus be delivered equipped with an actuator as soon as they leave the factory. Although preserving both the compactness, the aesthetic appearance of such shutters and their thermal and light insulating properties, these solutions are not quite satisfactory. Indeed, providing an internal housing in the amount of a frame, represents not only a manufacturing step and additional costs, but is also complex to achieve. In addition, these solutions generally assume to make the additional investment related to the presence of the actuators from the installation of the flaps. They are therefore not really suited to situations in which the addition of motorization is likely to intervene in a second time only, especially because the financial resources that must be spent can not or do not want to be released immediately. .

Furthermore, it has been found that the subsequent addition of a motorization to this type of swing shutters comprising a prefabricated chassis for automatically moving their shutter (s) between the open and closed positions, advantageously allows a postponement of the related costs, but also to date a number of disadvantages detrimental to the pursuit of their commercial development.

Thus, it has been found in particular that the fact of subsequently equipping a swinging flap already installed, a motorization system, is very often very tedious proving that the precision required is not always in adequacy with the component and its environment. The structure, sometimes not rigorous and not very square of the latter, can indeed imply multiple adjustments and adaptations detrimental to the functioning and the durability of the motorization system. Moreover, depending on the place of intervention, the operation of installation of the latter can be particularly delicate, especially when the opening concerned is not located on the ground floor.

In addition, it has been found that most of the engine systems currently being implemented as part of a Such application often do not guarantee the manual or automatic locking of the swing shutter in any situation. Indeed, most of them have a footprint such that it is impossible to install any means for mooring the leaves lintel and / or tablet.

Another disadvantage is further defined by the fact that the subsequent addition of a motor to a flap flap inevitably degrades the aesthetic appearance of the window in which the system is installed, and requires the intervention of an electrician to install the door. power supply necessary for the operation of the engines.

The object of the present invention is therefore to provide a frame for swing flap to overcome the drawbacks mentioned above, providing to equip, from its manufacture, elements to simplify subsequent fixing operations of the all of the elements that conventionally comprise means for automatically driving a leaf to its open or closed position and to ensure the proper positioning of all these elements regardless of the geometric accuracy of the location.

For this purpose, the subject of the invention is a flap door frame of the kind indicated in the preamble, characterized in that it comprises means for fixing means for automatically driving said leaf towards one of its open or closed positions. .

As will be described in more detail below, the fastening means of which the frame according to the invention is equipped during manufacture predetermined the positioning of the automatic drive means of a shutter flap. The fact of having a frame equipped, as soon as it leaves the factory, such fasteners, thus advantageously allows a precise and rigorous installation of the automatic drive means of a shutter flap, at any time, that this either before the installation of the chassis in an opening of a construction, during or after this installation, and in a particularly simplified way compared to state-of-the-art solutions. Thus, thanks to such a characteristic, the installation of motorization means of a shutter can be performed by both a professional and a non-professional and the most favorable period in terms of constraints and wishes of the client final.

In the case of implementation on a new construction, the frame according to the present invention also allows to preserve as much as possible the daylight of the opening concerned, since at least a part of the constituent elements of the means of Automatic drive of a shutter flap can then be housed in a reservation specifically provided for this purpose in the masonry.

The frame according to the invention is also characterized in that the automatic drive means of said leaf can comprise at least one actuator, whereas said fixing means comprise fixing elements of said actuator extending on the internal face of the second frame. in the angle formed between the first and the second frame or on the outer face of the second frame, at the rear of the plane defined by the first frame.

In this case, the fastening elements of said actuator may extend along an upper rail or along a lower rail of said first and second frames.

They may also extend on the internal face of the second frame along one of its lateral uprights and then be able, if necessary, to allow attachment of said actuator in the axis of said hinge.

Advantageously, the automatic drive means of said leaf can further comprise at least one solar collector for supplying power to said actuator, whereas said fixing means then comprise elements for fixing said solar collector extending on the external face. said first frame.

An additional feature is further defined by the fact that the frame according to the invention comprises means able to allow the locking of the leaf in the closed position.

Furthermore, the invention also provides that the fastening means may comprise a plurality of threaded holes or threaded rods suitably disposed on said frame, able to cooperate with a plurality of screws or nuts.

The invention further relates to a swing flap having at least one flap rotatably mounted between an open position and a closed position on a frame having the characteristics set forth above.
