Description

Description Title of the invention: Joinery equipped with a roller shutter transferable from the inside Technical field of the invention

[0001] The present invention relates to the general field of joinery.

[0002] — It relates more particularly to joinery of the type of door or window equipped of a roller shutter accessible from the inside. State of the art

[0003] — Door or window type joinery comprises a frame associated with a part fixed or opening, the assembly closes off a building opening fitted into a masonry structure separating an interior volume of the building, and a volume outside.

[0004] = The frame of the joinery may therefore include a support face which comes to to be placed against a flat, vertical support board prepared on the inside, around the perimeter of the building bay.

[0005] = This joinery frame is fixed to the support panel by means of screwed brackets, with the interposition of a sealing gasket between the two.

[0006] — At its upper part, the building bay may include a reservation for accommodating a roller shutter consisting of an axle around which a curtain is wound roller shutter, the ends of this axis being supported by lateral supports.

[0007] — The roller shutter can be housed in a casing, generally with an inverted U-shaped cross-section, supported by and integrated into the masonry structure, the side walls of This box forms the supports for the roller shutter axle.

[0008] — In this case, the window frame is installed independently of the housing and the roller shutter.

[0009] — Other types of window frames, called "integrated window and door units," are also known, including the The upper crossbar supports a roller shutter box that protrudes internally. or a half-box for a roller shutter that is integrated, during installation, into a L-shaped half-lintel structure.

[0010] — For boxes that are integrated into a half-lintel structure, access to the shutter rolling is achieved by means of a removable hatch which is positioned on the outside of the building, via a horizontal underside of the box.

[0011] — Access to the roller shutter of the visible boxes, protruding internally, is achieved by via a removable vertical panel set into a front wall of the trunk of roller shutter.

[0012] — The perimeter of the joinery frame still conventionally includes a a cover wing adapted to rest against an external face of a cladding, for example in the form of an added partition made of plasterboard, which provides the finish to the interior side of the building. But if there is an interior access hatch, the finish opposite the roller shutter, above the upper rail of the joinery frame, is not easy to achieve and can turn out to be unsightly. Presentation of the invention In order to remedy the aforementioned drawbacks of the prior art, the present invention proposes a door or window type joinery intended to close off a building opening having an upper recess for receiving a roller shutter, which joinery comprises a fixed frame associated with an opening sash, which frame comprises two side uprights, a lower rail, and an upper rail. which upper frame cross member comprises an upper face which includes a cover flange adapted to bear against an external face of an interior facing, for example made of plasterboard, which cover wing comprises a top cover wing face and a side cover wing face and which joinery is equipped with a roller shutter comprising a roller shutter axle supported by lateral supports, on which roller shutter axle a roller shutter curtain is wound, which roller shutter is at least partially integrated into a roller shutter box which includes a front panel of the box fitted with a removable access hatch, said front trunk wall comprising an external front trunk wall, a lower part of which is arranged in the plane of said lateral face of the cover wing, and supported against the latter, which external face of the front wall of the trunk and which lateral face of the cover wing are intended to be positioned in the plane of said external face of the interior facing, the joinery being characterized by the fact that it includes a finishing plate intended to conceal said external face of the front wall of the box and the joining lines between said external face of the front wall of the box and said external face of the interior facing, which finishing plate comprises an inner face intended to be oriented towards said outer face of the front wall of the trunk, an opposite outer face, an upper edge provided with a top edge, side edges and a lower edge provided with a bottom edge, which lower edge of said finishing plate is intended to bear against said upper face of cover wing, and which finishing plate includes means of fastening for its removable fastening with said upper frame rail and / or with said roller shutter box. Other non-limiting and advantageous features of the joinery according to the invention, taken individually or in all technically possible combinations, are as follows: - the means of securing include at least one means of embedding provided at the level of the lower edge of the finishing plate; - said at least one means of embedding comprises at least one embedding plate, a fixing portion of which is fixed against said inner face of the finishing plate, and an embedding portion of which, in the form of an embedding lip, extends projecting from said lower edge of said finishing plate, which recessed lip is inserted between said lateral face of cover wing and said external face of front wall of trunk; - the fastening means include fastening means by elastic interlocking arranged at the upper edge of the finishing plate: - the means of securing by elastic interlocking include at least one plate profile attached to the inner face of said finishing plate, which is adapted to cooperate with at least one complementary box profile attached to the front wall of the roller shutter box; - the finishing plate includes at least one recess in the angle formed between the edge of its upper border and its inner face, which recess is adapted to allow the said finishing plate to be separated from the roller shutter box, either manually or by means of an appropriate tool. Of course, the various features, variants, and embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention Furthermore, various other features of the invention become apparent from the attached description made with reference to the drawings which illustrate non-limiting embodiments of the invention and where: [Fig.1] is a schematic front view of a joinery according to the invention installed in a building bay and viewed from the interior side of this building; [Fig.2] is a schematic view of the joinery shown in [Fig.1], according to the vertical cutting plane 2-2; [Fig.3] is an enlarged view of the upper part of the joinery illustrated in [Fig.2]; [Fig.4] is an enlarged view of detail A of [Fig.3]; [Fig.5] is an enlarged view of detail B of [Fig.3]; [Fig.6] is a perspective view illustrating the joinery of figures 1 to 5 with its finishing plate, viewed from the outside of the building, and without the roller shutter. As can be seen in the attached figures, the joinery 1 closes a generally rectangular opening in building B, made in a masonry structure M between an interior volume I and the exterior E. The masonry structure M includes a top opening R for receiving a roller shutter 2. The joinery 1 shown is a window comprising a square or rectangular frame 3 associated with an opening 4, here of the French type, formed of a sash mounted on hinges. In general, joinery 1 can be a casement window or French window (opening in the English or French style), a sliding window or French window, or even an entrance door. Here, the frame 3 comprises two lateral frame uprights 31 connected by a lower rail 32 and by an upper rail 33, together forming a load-bearing frame for the opening leaf 4. In a conventional manner, this load-bearing frame 31, 32, 33 includes a projecting cover wing 6, which is adapted to rest against an interior facing, here in the form of an added partition C (and more particularly against an external face C1 of this added partition C) which provides the finish of the interior side of building I. The added partition C is for example made of plasterboard, plaster brick, wood panel, wainscoting or other. In particular, in figures 3 and 4, we notice this cover wing 6 provided on the upper face 331 of the upper frame cross member 33, which cover wing 6 comprises an upper face of cover wing 61 and a lateral face of cover wing 62. The upper face of the cover wing 61 is oriented upwards; and the lateral face of the cover wing 62 is oriented towards the outside E of the building. The roller shutter 2 which equips the joinery 1 includes a roller shutter curtain 21 (illustrated in dotted lines on the [Fig.2]) wound on a rotating shaft 22 carried by lateral supports (not shown). The roller shutter 2 is integrated into a roller shutter box 23 which includes a vertical front box wall 231, oriented towards the interior side I of the building, and which is equipped with a removable access hatch 2311. This access hatch 2311 is adapted to allow access to the inside of the roller shutter box 23, for maintenance or repair operations of the roller shutter 2. It includes here a flat profile 231 1a made of plastic, associated with an internal layer 2311b contributing to thermal insulation and possibly to acoustic attenuation. The front wall of the box 231 includes an external face of the front wall of the box 231a (oriented towards the interior side I of the building and constituted here by a front face of the flat profile 231 1a); and it is noted, in particular on figures 3 and 4, that a lower part 231a1 of this external face of the front wall of the box 231a is arranged in the plane of the lateral face of the cover wing 62, and is in contact with the latter. In this way, the external face of the front wall of the trunk 231a and the lateral face of the cover wing 62 are positioned in the same plane, and in the plane of the external face C1 of the added partition C. In the illustrated embodiment, the lower part 231al of the external face of the front wall of the trunk 231a which rests against the lateral face of the cover wing 62 is part of the access hatch 2311. In an alternative embodiment, the access hatch can be provided at a lower height and it is then a fixed part of the front face of the trunk that will rest against the cover wing 6. The added partition C includes an opening opposite the roller shutter box 23, and more particularly opposite the front wall of the box 231 of the roller shutter box 23, to allow access to the access hatch 2311 from inside building I. It is understood that junction lines 8 are then present between the external face of the front wall of the trunk 231a and the external face C1 of the added partition C, namely: - two vertical lateral lines 81, and - a horizontal longitudinal line 82. These junction lines 8 are made up of a space or a gap whose width is minimized but which can be on the order of a few millimeters. According to the invention, the joinery 1 includes a finishing plate 7 intended to conceal the external face of the front wall of the box 231a and the aforementioned junction lines 8 between the external face of the front wall of the box 231a and the external face C1 of the added partition C. This finishing plate 7 comprises an inner face 71 intended to be oriented towards the outer face of the front wall of the trunk 231a, an opposing outer face 72, an upper edge 73 with an upper edge 731, side edges 74 and a lower edge 75 with a lower edge 751, and: - this lower edge 751 of the finishing plate 7 rests against the upper face of the cover wing 61 of the cover wing 6 of the upper rail of the frame 33, and, - the finishing plate 7 also includes means of securing it for its removable securing with the upper rail of the frame 33 and / or with the roller shutter box 23 (in this case with the front wall of the box 231). The finishing plate 7 can be a few millimeters or a few centimeters thick. It can be made of any material, for example wood or plastic, depending in particular on the desired aesthetic. The means of securing the finishing plate 7 to the upper frame rail 33 and / or to the front panel of the box 231 in a removable manner include here: - recessed means 9 provided at the lower edge of the finishing plate 7, and - means of securing by elastic interlocking 10 arranged at the level of the upper edge 73 of the finishing plate 7. Preferably, as can be seen in particular in figures 3 and 4, the embedding means include at least one embedding plate 9, integral with the inner face 71 of the finishing plate 7 and of which a part protrudes to fit between the lateral face of the cover wing 62 and the outer face of the front wall of the trunk 231a. As illustrated in Fig. 6, several mounting plates 9 (in this case three) are preferably provided, distributed along the length of the lower edge 75 of the finishing plate 7. The mounting plates 9 have a low thickness, for example between 0.2 and 0.8 mm, to allow their insertion between the cover wing 6 and the external face of the front wall of the box 231a (constituted here by a part of the access hatch 2311, but which, alternatively, can be constituted by a fixed part of the front wall of the box). The mounting plates 9 are preferably flat; they include a fixing part 91 which is fixed (for example by gluing or adhesive) against the inner face 71 of the finishing plate 7, and a recessed part 92, in the form of a recessed lip, which extends outward from the lower edge 751 of the finishing plate 7. The 9 mounting plates can be made of plastic or metal (for example, they are made of 3 / 10ths of a millimeter thick stainless steel), As an alternative embodiment, the plurality of plates 9 can be replaced by a single longitudinal plate extending over all or virtually all of the length of the lower edge 75 of the finishing plate 7. Such a recessed system has the advantage of being easy to implement, not requiring machining of the finishing plate or the upper rail of the frame, and being completely invisible. As illustrated in [Fig.5], the means of securing by elastic interlocking 10 include a plate profile 101, longitudinal, integral with the inner face 71 of the finishing plate 7, which is adapted to cooperate with a box profile 102, longitudinal and complementary, integral with the front wall 231 of the roller shutter box 23. The longitudinal profile of the plate 101 can extend over the entire length or practically the entire length of the upper edge 73 of the finishing plate 7; and the longitudinal profile of the trunk 102 can extend over the entire length or practically the entire length of the front wall of the trunk 231 (preferably on a fixed part of the front wall of the trunk 231 and therefore not on the access hatch 2311). This longitudinal interlocking fastening solution stiffens the upper part of the finishing plate 7 and prevents excessive deformation when the finishing plate is removed. It also has the advantage of being completely invisible. In one embodiment variant, a plurality of pairs of interlocking profiles 101-102 can be provided, distributed along the length of the finishing plate 7 and the front wall of the trunk 231. The plate profile(s) 101 can be joined to the inner face 71 of the finishing plate 7 by gluing, adhesive, screwing or otherwise. On the other hand, the trunk profile(s) 102 can be joined to the trunk front face 231 by gluing, adhesive, screwing or otherwise; or they can be made as a single piece with said trunk front face 231. In alternative embodiments, the attachment of the finishing plate 7 to the front wall of the trunk 231, at the level of its upper edge 73, can be achieved by magnetization, or, if a visible fixing is chosen, by a lock, a latch or other. As can be seen in [Fig.5], the finishing plate 7 preferably includes at least one gripping recess 76, provided in the angle formed between the edge 731 of its upper border 73 and its inner face 71. Such a reservation 76 is adapted to allow the finishing plate 7 to be separated from the roller shutter box 23, either manually or by means of an appropriate tool. This reservation 76 can be made along the entire length of the upper edge of the finishing plate 7, or on only part or some parts of it. length. The positioning of the finishing plate 7 is achieved by inserting the protruding part 92 of the plates 9 between the side face of the cover wing 62 and the external face of the front wall of the trunk 231a, with the finishing plate 7 at an angle; then by pivoting the finishing plate 7 around its lower edge 751 to activate the interlocking fastening means 10. The removal of the finishing plate 7 is carried out by a reverse operation, by pulling on its upper edge 73 from the reservation 76 to deactivate the interlocking means 10, then by disengaging the mounting plates 9. It should be noted that in one variant of the design the roller shutter can be replaced by any similar structure such as an adjustable sunshade, for example. If necessary, a ventilation air inlet can be fixed to the external face 72 of the finishing plate 7, opposite suitable mortises provided in said finishing plate 7 and in the front wall of the box 231. An annular seal, positioned between the finishing plate 7 and the front wall of the trunk 231, around the perimeter of the two mortises, can then ensure sealing, by its compression during the installation of the finishing plate 7.
