Description

Title of the invention: PROTECTIVE FRAME FOR BUILDING JOINERY AND BUILDING EQUIPPED WITH AT LEAST ONE SUCH PROTECTIVE FRAME 1. Scope of the proposed technique

[0001] The field of the invention is that of exterior joinery of buildings, in particular light-framed buildings.

[0002] The invention relates more particularly to a protective frame for such joinery.

[0003] Such protective framing has many applications, particularly for light-framed or structural buildings. 2. Prior art

[0004] Among the different types of buildings known, there are in particular those with a light frame.

[0005] In this category of buildings, there are in particular timber-framed buildings, such as those equipped with ventilated cladding or external insulation with added cladding, for example.

[0006] In such buildings, the framework is composed of panels comprising a wooden frame, formed of vertical uprights and horizontal crosspieces assembled, an insulator placed between the uprights of the frame and one or more boards attached to one of the faces.

[0007] Such panels, in particular those intended to form the cladding walls of the building (i.e. facade walls), also have a first sealing film, called a vapor barrier, applied to the inner face of the panel, and a second sealing film, called a rain barrier, applied to the outer face of this same panel.

[0008] Obviously, some of these facade panels have openings, also called bays, for receiving exterior joinery.

[0009] These exterior joinery pieces, whether they are, among others, windows, doors or French windows, generally comprise a frame receiving one or more openings, opening inwards, and, where appropriate, one or more fixed panels.

[0010] The assembly of such exterior carpentry requires several operations, the main ones of which are described below.

[0011] Traditionally, for this type of building, it is advisable to add a vapor barrier strip at the level of the bay and to secure it at one end by means of an adhesive. It is also advisable to add, on the lower wall of the bay, a crosspiece of support on the lower side of the joinery. This support crosspiece also ensures the junction of the sealing elements. The lateral and upper sides of the joinery are secured directly to the vapor barrier strips added to the side and upper walls. Finally, separate edges are added to the side and upper walls of the bay to ensure a watertight junction between the exterior of the joinery and the exterior of the facade panel. These edges are made with profiles cut at 90° which come to rest, and rest, on the support crosspiece.

[0012] To prevent rainwater infiltration in particular, at least the joinery support crosspiece and the upper edge are covered with metal trim flaps, generally made of aluminum. These flaps thus guarantee the longevity of the joinery.

[0013] Such a joinery mounting solution has many disadvantages.

[0014] First of all, the support crosspiece and the edges are separate elements of different structures. These structural disparities complicate the assembly of the joinery in particular. It is also likely to cause thermal, acoustic and / or hydraulic weaknesses at the support point. This therefore results in functional and visual nuisances.

[0015] Furthermore, the support crossbar and the edges are made of different materials. The support crossbar is commonly made of aluminum while the edges are made of wood. This therefore increases the aforementioned nuisances.

[0016] There is therefore a need to provide a technique for cladding (or protecting) the exterior joinery of buildings which does not have all or part of the disadvantages of the current solution.

[0017] There is also a need to provide such a technique usable on different types and / or categories of buildings. 3. Summary of the proposed technique

[0018] The proposed technique relates, according to a first aspect, to a protective frame for building joinery, comprising four sides respectively having: - a first surface intended to be placed opposite an exterior wall of a frame of the joinery, the first surface carrying sealing elements between the frame and the frame; - a second surface, opposite the first surface, of partial overlap of an exterior wall of the building; and - at least one third surface for connecting the first and second surfaces.

[0019] A frame conforming to the proposed technique makes it possible, particularly due to its single-piece appearance, to simplify the structure of the joinery cladding elements. This therefore results in a simplification of the assembly operations of the carpentry cladding elements.

[0020] Such a frame also helps to ensure a long lifespan for the joinery by protecting the frame from external hazards (shocks, rain, etc.).

[0021] According to a particular characteristic of the proposed technique, the four sides of the frame have similar cross-sections.

[0022] This makes it possible in particular to provide uniform sealing, or even thermal and / or acoustic performance, on the different sides of the bay. This also makes it possible to provide a uniform aesthetic finish.

[0023] Preferably, according to this particular characteristic, the four sides of the frame are formed from a single profile.

[0024] Such a solution makes it possible in particular to minimize the manufacturing costs of the frame as well as to reduce the number of separate parts necessary for its design. This makes it possible to simplify its assembly and minimize the risks of water infiltration at the junctions of the assembled separate parts.

[0025] According to another particular characteristic of the proposed technique, the frame supports at least one insulation element intended to rest on the frame of the joinery.

[0026] The implementation of an insulation element makes it possible in particular to improve the thermal and / or acoustic performance of the bay. This results in comfort for the occupants of the building.

[0027] According to another particular characteristic of the proposed technique, the frame comprises at least one portion for fixing to the frame of the joinery.

[0028] Thus, the frame is held securely on the joinery. This contributes to the durability of the installation. The implementation of such fixing portions is particularly advantageous when it is not possible to directly assemble the frame to the frame of the joinery, in particular by embedding.

[0029] According to another particular characteristic of the proposed technique, the third surface carries a reinforcement structure for the frame.

[0030] Such a reinforcement structure makes it possible in particular to improve the mechanical strength of the frame. This therefore results in a greater longevity of the frame, in particular with regard to shocks and / or impacts from the external environment.

[0031] According to another particular characteristic of the proposed technique, the insulation element is carried by the reinforcing structure.

[0032] According to another particular characteristic of the proposed technique, the fixing portion is carried by the reinforcing structure.

[0033] Such arrangements make it possible in particular to simplify the overall structure of the framework.

[0034] The proposed technique relates, according to a second aspect, to a building comprising at least one facade panel in which at least one bay is provided and comprises at least one protective joinery frame as described previously. 4. List of Figures

[0035] The proposed technique, as well as the various advantages that it presents, will be more easily understood, in the light of the following description of illustrative and non-limiting embodiments thereof, and of the appended drawings among which: - [Fig.l]: [Fig.l] illustrates, according to a partial schematic view in cross section, an example of protective framing for carpentry, according to a first embodiment of the proposed technique, arranged in a first example of a timber-framed building; - [Fig.2A], [Fig.2B] and [Fig.2C]: Figures 2A to 2C illustrate, according to partial schematic views in cross sections, the framing of [Fig.l] arranged in other examples of buildings; - [Fig.3]: [Fig.3] illustrates, according to a partial schematic view in cross section, an example of a protective frame for joinery according to a second embodiment of the proposed technique; and

[0037] 5. Detailed description of the proposed technique

[0038] For the sake of clarity, the same elements are designated by the same references in the different figures to which the symbol “'” is added incrementally between each embodiment.

[0039] Furthermore, the terms orientation and positioning are subsequently used with arbitrary reference to an installed position of the protective frame, when the latter is arranged at least partially inside a bay provided in a panel of a building, and is oriented according to the plane of the panel (i.e. substantially perpendicular to the ground).

[0040] Obviously, a protective framework conforming to the proposed technique is in no way limited to timber-framed buildings and can be implemented in all types of light-framed buildings (equipped with a rigid or flexible rain screen, such as buildings with metal frames or other materials with ventilated or non-ventilated cladding) or those known as structural work.

[0041] 5.1 General principle

[0042] The proposed technique relates to a new protection approach (acoustic, thermal, hydraulic, etc.) of carpentry, the general principle of which is based on a protective frame comprising four sides presenting respectively: - a first surface intended to be placed opposite an exterior wall of a frame of the joinery, the first surface carrying sealing elements between the frame and the frame; - a second surface, opposite the first surface, of partial overlap of an exterior wall of said building; and - at least one third inclined surface connecting the first and second surfaces.

[0043] The proposed technique also relates to a building, in particular with a light frame, comprising at least one such protective frame for joinery.

[0044] 5.2 Description of an illustrative embodiment

[0045] [Fig.l] illustrates, in a partial cross-sectional view, an example of a protective frame, in accordance with a first embodiment of the proposed technique, coupled with joinery arranged in a bay of a timber-framed building according to a first structural example.

[0046] Conventionally, a facade panel 2 of a timber-framed building comprises a wooden frame 21, an insulator 22, such as mineral wool, and one or more boards 23 attached to one face, intended to be oriented towards the outside preferably.

[0047] This facade panel 2 further comprises a first sealing film 24, called a vapor barrier, attached to the inner face of the facade panel 2, and a second sealing film 25, called a rain barrier, attached to the outer face of this same facade panel 2. Furthermore, in the example illustrated, a cladding 26 is attached to the rain barrier 25 to ensure, from the outside, the thermal insulation of the facade panel 2. In such a case, the cladding 26 delimits the outer wall 260 of the building.

[0048] In the facade panel 2 is provided a bay, of which only the lower wall 210 is visible in [Fig.l], in which an external joinery 3 is arranged.

[0049] This joinery 3 conventionally comprises a frame 31 receiving one or more openings 32, opening inwards, and, where appropriate, one or more fixed panels.

[0050] The frame 31 of the joinery 3 is mounted in the bay of the facade panel 2 and secured to it by appropriate means.

[0051] According to the proposed technique, a protective frame 1 is attached to the joinery 3, and more precisely to the exterior wall 310 of the frame 31.

[0052] The frame 1 comprises a rigid body 10 formed of four sides, one for each side of the associated joinery, comprising respectively: - a first surface 110 located opposite the outer wall 310 of the frame 31 and carrying sealing elements 111 between the frame 1 and the frame 31; - a second surface 120, opposite the first surface 110, partially overlapping the exterior wall 260 of the building; - a third inclined surface 130 connecting the first and second surfaces 110, 120; and

[0053] - a fourth surface 140 extending perpendicularly the second surface 120 on the side of the first surface 110 so as to substantially form a frame return.

[0054] In this embodiment, although not shown, the four sides of the frame 1 have identical cross-sections. The body 10 of the frame 1 thus has a continuous structure. The different surfaces, and associated elements detailed below, therefore extend over the entire length of each side.

[0055] Such an arrangement allows in particular easy assembly of the frame as well as uniform protection of the joinery. This also results in an improvement in the overall aesthetics of the joinery.

[0056] In this embodiment, the frame 1 comprises a fixing portion 150, intended to cooperate with suitable fixing means, so as to secure the frame 1 to the frame 31 of the joinery 3.

[0057] The implementation of such fixing portions is particularly advantageous when it is not possible to directly assemble the frame 1 to the frame 31 of the joinery, in particular by embedding.

[0058] Furthermore, in this embodiment, the frame 1 comprises a reinforcing structure 131 carried by the third surface 130.

[0059] This reinforcement structure 131 is arranged on the inside of the bay, that is to say substantially opposite the elements of the facade panel 2, so as not to disturb the aesthetics of the joinery.

[0060] In the example illustrated, the frame 31 of the joinery 3 is mounted on the wall 210 of the bay formed in the facade panel 2 by means of a joinery receiving frame 4.

[0061] This receiving frame 4 is configured to ensure the watertightness and airtightness of the bay. To do this, the frame comprises four sides, each of which has a plurality of sealing elements with the joinery 3 and, directly or indirectly, with the facade panel 2.

[0062] In this example, the sides of the body 10 of the frame 1 are formed from separate profiles mechanically assembled together, by welding, gluing or screwing for example. Where appropriate, a sealing element is arranged between the assembled profiles.

[0063] More precisely, the four sides of the frame have identical cross-sections and are joined at beveled cutouts at 45° angles. The body 10 of the frame 1 thus has a so-called continuous structure.

[0064] Such a continuous structure makes it possible in particular to obtain an alignment of the first surface 110 for receiving the sealing element 111 on each side. Thus, the sealing element 111 in question can be in one piece and arranged around the perimeter of the frame 1, so as to define a loop.

[0065] Such a continuous structure also allows the frame 1 to have, in particular by means of the reinforcing structure 131, uniform mechanical resistance.

[0066] In this example, the sealing elements are made of a polymer material, such as Polyvinyl ethers (PVE). Obviously, any flexible material that intrinsically has similar sealing properties can be used, namely PVC, thermoplastic elastomers (TPE), ethylene-propylene-diene monomer rubbers (EPDM), etc.

[0067] Furthermore, in the example illustrated, the fixing portion 150 is carried by the reinforcing structure 131. This makes it possible in particular to simplify the design and manufacture of the frame 1.

[0068] Still in this example, the first surface 110 of the frame 1 is positioned as close as possible to the leaf(s) 32 of the joinery 3 so as to optimally conceal the frame 31.

[0069] This makes it possible in particular to improve the thermal performance of the joinery, by minimizing its contact surfaces, and therefore its heat exchange, with the external environment of the building.

[0070] Furthermore, the frame 1 is secured to the frame 31 of the joinery 3 by means of a fixing screw passing through the frame 31 and being housed in the fixing portion 150.

[0071] Obviously, a frame conforming to the proposed technique is a finishing element, the assembly of which occurs at the end of the installation procedure of the joinery and associated elements.

[0072] More precisely, the frame 1 is introduced into the opening from the outside of the facade panel 2 until the sealing elements 111 come into contact with the outside wall 310 of the frame 31 of the joinery 3. The frame 1 is then secured to the facade panel 2, by means of suitable means. The installation (or assembly) of the frame 1 is therefore relatively simple.

[0073] Figures 2A to 2C illustrate, according to partial schematic views in cross sections, a frame conforming to this first embodiment arranged in other examples of buildings.

[0074] [Fig.2A] illustrates a compliant frame 1 arranged in a facade panel 2A of a timber-framed building equipped with ventilated cladding.

[0075] [Fig.2B] illustrates a compliant frame 1 arranged in a facade panel 2B of a timber-framed building equipped with external thermal insulation.

[0076] [Fig.2C] illustrates a compliant frame 1 arranged in a facade panel 2C of a metal-framed building.

[0077] It therefore appears that a framework conforming to the proposed technique can be implemented in buildings of different structures.

[0078] 5.3 Other illustrated embodiments

[0079] [Fig. 3] illustrates, in a partial cross-sectional view, an example of a protective frame, in accordance with a second embodiment of the proposed technique, coupled with joinery arranged in a bay of a timber-framed building according to a second structural example.

[0080] This second embodiment is distinguished from the first embodiment essentially by the presence of an insulation element. For reasons of clarity and conciseness, the elements common and identical to the first embodiment are not described.

[0081] In this second embodiment, the frame 1' carries an insulation element 132 intended to rest on the frame 31' of the joinery 3'.

[0082] Thus, by filling the space between the frame and the woodwork with a thermal and / or acoustic insulation material, the insulation performance of the woodwork and ultimately that of the building can be improved.

[0083] In the example illustrated, the frame 31' of the joinery 3' is mounted and secured to the wall 210' of the bay without an intermediate frame for managing the sealing.

[0084] Furthermore, in the example illustrated, the insulation element 132 is carried by the reinforcement structure 131' of the frame 1'.

[0085] Figures 4A and 4B illustrate, according to partial schematic views in cross sections, an example of a protective frame for joinery according to a third embodiment of the proposed technique. More precisely, [Fig.4A] is a partial schematic view, according to a cross section, of the upper side of the frame and of the facade panel inside which it is arranged. [Fig.4B] is a partial schematic view, according to a cross section, of a lateral side of this same frame and of this same facade panel inside which it is arranged.

[0086] This third embodiment is distinguished from the first embodiment essentially by a framing structure adapted to the passage of a concealing element. For reasons of clarity and conciseness, the elements common and identical to the first embodiment are not described.

[0087] This third embodiment is therefore essentially intended for window-type joinery for which a concealment system is provided. This is not necessarily the case for all the windows in a building.

[0088] In this third embodiment, the frame 1" has a slot 161 or a recess 162 for the passage of a movable part of a concealment system 500 attached to the bay of the building.

[0089] Such an arrangement allows in particular the frame to ensure its function of protecting the woodwork without hindering the implementation and operation of a concealment system, such as a roller shutter for example.

[0090] In the example illustrated, the 4" joinery receiving frame houses, in its upper 41" side, the concealment system 500, so as to define a single-piece assembly.

[0091] In order to allow the operation of this occultation system 500, the upper side of the frame 1" has a through slot 161, outside of which passes the movable part of the occultation system 500, as illustrated in [Fig.4A]. The lateral sides of the frame 1" have respectively a recess 162 for receiving the lateral ends of the movable part of the occultation system 500, as illustrated in [Fig.4B].

[0092] Furthermore, this slot 161 and these recesses 162 are provided in the third surface 130" connecting the first and second surfaces.

[0093] 5.4 Other embodiments not illustrated and variant embodiments

[0094] In the illustrated embodiments, the body of the frame is made of an aluminum material. Obviously, any rigid material with intrinsically similar mechanical properties can be used. For example, a frame made of a plastic material, such as PVC, or composite can be considered. The frame can also be made of wood or steel, for example.

[0095] Alternatively, the sides can be produced in the form of separate and assembled profiles, where appropriate with the use of a sealing element between the mechanically fixed profiles. In the illustrated embodiments, the frame body is produced via a single profile, locally cut and hollowed out to ensure the connection and fixing, by welding for example, of different sides.

[0096] In some illustrated embodiments, the body of the frame has a so-called continuous structure in order to allow the sides to have identical cross-sections. In at least one other embodiment, not illustrated, the body of the frame is formed from several profiles having different cross-sections. For example, to allow the passage of a screening element. These variations in cross-sections may result from the initial structures of the profiles and / or from machining operations carried out on these profiles. In a way generally, running all the above cases, it can be considered that the cross sections are similar, that is to say at least similar, or even identical.

[0097] In the illustrated embodiments, the four sides forming the body of the frame have identical cross-sections and are joined at beveled cutouts at 45° angles. In another embodiment, not illustrated, the four sides of the frame have identical cross-sections and are joined at cutouts at 90° angles. Such an arrangement simplifies the manufacture of the frame.

[0098] In the illustrated embodiments, the frame comprises a reinforcing structure. In another embodiment, not illustrated, the frame is devoid of such a structure. Thus, the frame is simplified and therefore easier to manufacture.

[0099] In the illustrated embodiments, the protective frame is secured to the frame of the joinery by means of fixing screws. Obviously, any fixing means (mechanical locking) allowing the frame to be secured to the frame can be envisaged. For example, the securing can be carried out by means of snap-fastening means, reversible or not, or by gluing. According to another example, the securing can be carried out by means of clamps. Thus, the fixing means can be visible or invisible.

[0100] In the illustrated embodiments, the frame has a (fourth) surface for partially closing the air gap formed between the cladding of the facade panel and the frame. In another embodiment, not illustrated, the frame is devoid of such a surface. This makes it possible to simplify the structure of the frame, in particular for buildings for which external ventilation of its structural elements is not necessary.

[0101] In the illustrated embodiments, the connection of the first and second surfaces is achieved by a single (third) inclined surface. In another embodiment, not illustrated, the connection of the first and second surfaces is achieved by a succession of (third) surfaces having different inclinations. This makes it possible in particular to optimize the evacuation of rainwater. In yet another embodiment, not illustrated, the connection of the first and second surfaces is achieved by a single straight surface, i.e. not inclined.

[0102] Obviously, the proposed technique is not limited to the embodiments described above and provided solely as an example. It encompasses various modifications, alternative forms and other variants that may be envisaged by those skilled in the art within the framework of the proposed technique and in particular all combinations of the different embodiments described above, which may be taken separately or in association.

[0103] According to different aspects, the proposed technique therefore presents all or part of the following advantages, depending on the embodiments and / or variants selected:

[0104] - improve the thermal performance of the bay;

[0105] - improve the acoustic performance of the bay;

[0106] - improve the overall sealing of the bay;

[0107] - simplify the operations of mounting the carpentry cladding elements;

[0108] - simplify the structure of the carpentry cladding elements;

[0109] - propose a solution adaptable to different types of buildings;

[0110] - propose a simple manufacturing solution;

[0111] - guarantee significant longevity;

[0112] -etc.
