Description

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

The present invention relates to the field of construction and will find an application both in the field of new constructions and in that of the renovation of old buildings. In the latter case, the implementation of swing shutters with prefabricated frames has proved to be particularly advantageous given that these devices make it possible to overcome many structural constraints, require little or no masonry work and are therefore very easy to install, whatever the environment, while guaranteeing perfect thermal and light sealing.

Just as for rolling shutters, there are currently solutions for motorizing swing shutters of the type comprising a prefabricated frame, making it possible to improve their comfort of use and to avoid the tedious and time-consuming closing/closing operation. manual opening.

Such a solution is known in particular from the document FR 2 957 113 which plans to install an actuator in an interior housing provided in each of the side uprights of the frame, parallel to the axis of a hinge. Another similar solution, providing for the integration of an actuator in the upper cross member of the frame, specifically configured to provide a housing, is described in the document WO 2008/093189 .

Such products can thus be delivered equipped with an actuator as soon as they leave the factory. Although making it possible to preserve both the compactness and the aesthetic appearance of such swing shutters as well as their heat and light insulation properties, these solutions are not entirely satisfactory. In fact, providing an internal housing in an upright of a frame not only represents a manufacturing step and additional costs, but also proves to be complex to achieve. Moreover, these solutions generally assume making the additional investment linked to the presence of the actuators as soon as the shutters are installed. They are therefore not really suitable for situations in which the addition of motorization is likely to occur only later, in particular because the financial resources that must be devoted to it cannot 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 shutter comprising a prefabricated frame making it possible to automatically move their leaf(s) between the open and closed positions, advantageously allows a deferral of the related costs, but also present to date a certain number of disadvantages prejudicial to the continuation of their commercial development.

Thus, it has turned out in particular that the fact of retrofitting a swing shutter already installed, with a motorization system, very often proves to be particularly tedious because the precision required is not always in line with the shutter. and its environment. The structure, which is sometimes not very rigorous and not very square, can indeed involve adjustments and multiple adaptations that are detrimental to the operation and durability of the motorization system. Moreover, depending on the place of intervention, the installation operation of the latter can prove to be particularly delicate, in particular when the opening concerned is not located on the ground floor.

In addition, it has been found that most motorization systems implemented today as part of a such an application often does not guarantee manual or automatic locking of the shutter in any situation. Indeed, most of them are so bulky that it is impossible to install any means allowing the leaves to be moored to the lintel and/or to the shelf.

Another disadvantage is also defined by the fact that the subsequent addition of a motorization to a swinging shutter inevitably degrades the aesthetic appearance of the window in which the system is installed, and requires the intervention of an electrician to install the power supply necessary for the operation of the motors.

The object of the present invention is therefore to propose a frame for a swing shutter which makes it possible to overcome the drawbacks mentioned above, by providing for it to be equipped, from its manufacture, with elements making it possible to simplify the subsequent fixing operations of the all of the elements that conventionally include means for automatically driving a leaf towards its open or closed position and to guarantee the proper positioning of all these elements regardless of the geometric precision of the location.

To this end, the subject of the invention is a leaf shutter 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 fixing means with which the frame according to the invention is equipped during its manufacture predetermine the positioning of the automatic drive means of a shutter leaf. The fact of having a chassis equipped, as soon as it leaves the factory, with such fasteners, thus advantageously allows precise and rigorous installation of the automatic drive means of a shutter leaf, at any time, whether either before the installation of the frame in an opening of a construction, during or after this installation, and this in a particularly simplified manner compared to state-of-the-art solutions. Thus, thanks to such a characteristic, the installation of means of motorization of a swing shutter can be accomplished both by a professional and a non-professional and at the most favorable period in terms of constraints and wishes of the customer. final.

In the case of implementation on a new construction, the frame according to the present invention also makes it possible to preserve the daylight of the opening concerned as much as possible, given that at least part of the constituent elements of the means of The automatic drive of a shutter leaf 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 may comprise at least one actuator, while 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 external face of the second frame, at the rear of the plane defined by the first frame.

In this case, the fixing elements of said actuator can extend along an upper crosspiece or along a lower crosspiece of said first and second frames.

They can also extend over the inner face of the second frame along one of its side uprights and then be capable, if necessary, of allowing said actuator to be fixed in the axis of said hinge.

Advantageously, the automatic drive means of said leaf may further comprise at least one solar sensor for supplying energy to said actuator, while said fixing means then comprise fixing elements of said solar sensor extending on the external face. of said first frame.

An additional characteristic is further defined by the fact that the frame according to the invention comprises means capable of allowing the leaf to be locked in the closed position.

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

The invention further relates to a leaf shutter comprising at least one leaf mounted to rotate between an open position and a closed position on a frame having the characteristics stated above.

The shutter 1, 1', 1" further comprises means for automatically driving the leaves 5, 5' around each axis 11, 11' in order to switch them between their open position and their closed position.

Furthermore, the frame 2, 2', 2" has an "L" section in which it consists of a first frame 7 intended to be pressed against a zone of the wall 4 bordering the opening 3 and of a second frame 8, perpendicular to the first, intended to extend into the opening 3. The first and second frames 7, 8 have an outer face 70, 80 and an inner face 71, 81 and each comprise two parallel side uprights 72, 73 , 82, 83 interconnected by an upper crosspiece 74, 84 and a lower crosspiece 75, 85.

In accordance with the invention, the frame 2, 2', 2" comprises means for fixing means for automatically driving the leaves 5, 5' towards one of their open or closed positions. It should be noted that the expression "fixing means" designates any means making it possible to position correctly on said frame 2, 2', 2" then to fix there, if necessary by complementary assembly means, the various elements forming the automatic drive means leaves 5. By way of example, the fastening means may thus comprise a plurality of tapped holes or threaded rods suitably arranged on the frame 2, 2', 2" capable of cooperating with a plurality of screws or nuts.

The means for automatically driving the leaves 5, 5' comprise a set of elements, including two actuators 9, each dedicated to the actuation of a leaf 5, 5' and each consisting of a drive motor of the electric type , housed in a casing, and coupled to means for opening/closing each leaf 5, 5'.

In the first two embodiments illustrated in figures 1-2 and 3-5 , the latter comprise a compass arm 12, 12', one end of which is engaged with an actuator 9, 9', while the other end is movable in translation inside a slide 13, 13' made integral with a leaf 5, 5'. In the alternative embodiment illustrated in figure 1 and 2 , the actuator fixing elements 9 with which the frame 2 is equipped during its manufacture, such as for example a plurality of tapped holes or threaded rods, extend along an upper crosspiece 74, 84 of the first and second frames 7, 8 of frame 2, under the outer face 80 of the second frame 8, at the rear of the plane defined by the first frame 7. In accordance with the alternative embodiment illustrated in figures 3 to 5 , the frame 2' is equipped during its manufacture with elements for fixing the actuators 9, such as for example a plurality of tapped holes or threaded rods, extending along an upper crosspiece 74, 84 of the first and second frames 7, 8 of frame 2', on internal face 81 of second frame 8, in the angle formed between first and second frames 7, 8.

As illustrated in figures 6 to 8 , it is also possible to equip a 2" frame according to the invention with actuator fixing elements 9 extending on the internal face 81 of the second frame 8, along its side uprights 82, 83, and provide capable of allowing fixing of the actuators 9 in the axis of the hinges 6, so that each of them can be coupled with a hinge 6.
