Abstract

The structure has a groove (3) to tightly house an elastic mounting tape (8) whose openings (7) permits to receive vertical rods (5) of a grille (4) in a tight manner. The openings are tangentially positioned with respect to median plane (18) of the tape. Outer sides of the tape constitute extension of outer side (12) of a profile (2). The rods cause spacing of lower part of the tape in order to lock the tape in the profile.

Description

2880058 12880058 1

L'invention concerne une structure (fig. 3) en profilés (2;21), extrudés en aluminium, PVC, PS, ABS ou d'autres thermoplastiques et/ou thermodurcissables ou pultrudés en résine polyester, acrylique, époxy ou toute autre matière synthétique armée de fibre de verre, carbone, aramide et/ou toute autre fibre ou laminés voire pliés en tôle (22) d'acier, aluminium ou tout autre métal comportant des rainures (3) à recevoir des grillages (4) en tiges métalliques soudées (9) ou ondulées. Il est évident que l'insertion d'un tel grillage (4) directement dans la rainure (3) ou par l'intermédiaire d'un joint de montage pour vitres et/ou panneaux (31) (fig. 1 et 2) fait apparaître sur le profilé (2;21) au niveau de la rainure (3) des ouvertures ( 33) entre les tiges (5) du grillage (4). De telles ouvertures interdisent naturellement l'emploi de ces structures comme protections et/ou tamis dans toutes applications ou les dépôts de débris, poussière, liquides sont proscrits à savoir l'industrie alimentaire, les salles propres, les cartoucheries, etc... The invention relates to a structure (FIG 3) made of profiles (2; 21) extruded from aluminum, PVC, PS, ABS or other thermoplastics and / or thermosetting or pultruded in polyester resin, acrylic resin, epoxy resin or any other material. reinforced synthetic fiberglass, carbon, aramid and / or any other fiber or rolled or folded sheet steel (22) of steel, aluminum or any other metal having grooves (3) to receive grids (4) in metal rods welded (9) or corrugated. It is obvious that the insertion of such a grid (4) directly into the groove (3) or through a window and / or panel mounting joint (31) (FIGS. appear on the profile (2; 21) at the groove (3) openings (33) between the rods (5) of the grid (4). Such openings naturally prohibit the use of these structures as protections and / or sieves in all applications or deposits of debris, dust, liquids are prohibited ie the food industry, clean rooms, cartouches, etc ...

Des solutions utilisant des lèvres d'étanchéité (32), telles qu'utilisées pour le montage des vitres ne donnent guère satisfaction en raison des ouvertures restantes à proximité des tiges (5) du grillage (4), des solutions utilisant des mastics à appliquer au moment du montage ne permettent pas un montage rapide et économique. Solutions using sealing lips (32), as used for mounting the panes do not give much satisfaction because of the remaining openings near the rods (5) of the grid (4), solutions using mastics to apply at the time of assembly do not allow a quick and economical assembly.

La présente invention, détaillée par la suite, propose une solution simple et efficace à ce problème. The present invention, detailed later, provides a simple and effective solution to this problem.

Fig. 3: les tiges (5) du grillage (4) sont logées d'une façon serrée et étanche dans les ouvertures (7) d'un ruban de montage élastique (8) qui est lui-même logé serré et étanche dans la rainure (3) d'un profilé (2) extrudé. La face extérieure ( 10) se trouve sensiblement dans le même plan ( 12) que la face extérieure du profilé (2;21) à proximité de la rainure (3). Ici, les ouvertures (7) dans ledit ruban (8) sont positionnées tangentiellement par rapport au plan médian (18) du ruban (8) pour permettre un montage sans déformation des tiges 2880058 2 verticales (5) et horizontales (51) naturellement décalées d'un grillage soudé (4) (voir aussi Fig. 4). L'élasticité du ruban (8) autre que contribuant à la parfaite étanchéité entre les tiges (5;51) du grillage (8) et du profilé (2;21) permet de compenser les tolérances de fabrication d'entraxe (52) du grillage (4). Le ruban (8) même ici est réalisé en matière pleine ou expansée à alvéoles ouvertes et/ou fermées à base de PE, PP, PVC, ABS ou élastomère tel que caoutchouc de toute sorte et/ou silicone (FIG. 4). Fig. 3: the rods (5) of the mesh (4) are tightly and sealingly fitted in the openings (7) of an elastic mounting tape (8) which is itself tight and sealed in the groove ( 3) an extruded profile (2). The outer face (10) is substantially in the same plane (12) as the outer face of the profile (2; 21) near the groove (3). Here, the openings (7) in said ribbon (8) are positioned tangentially with respect to the median plane (18) of the ribbon (8) to allow mounting without deformation of the vertical rods 2880058 2 (5) and horizontal (51) naturally offset welded wire mesh (4) (see also Fig. 4). The elasticity of the ribbon (8) other than contributing to the perfect seal between the rods (5; 51) of the grid (8) and the profile (2; 21) makes it possible to compensate for the manufacturing tolerances of the center distance (52). toasting (4). The ribbon (8), even here, is made of solid or expanded open cell and / or closed material based on PE, PP, PVC, ABS or elastomer such as rubber of any kind and / or silicone (FIG.

Fig. 5 montre une variante de la solution pour profilés (2) pliés en tôle (22) dont le ruban de montage (8) capote la rainure (3) avec sa partie extérieure (13) plus large que l'ouverture (34) de ladite rainure (3). Le ruban comporte également des éléments d'ancrage (14) le verrouillant sous les talons (31) de la rainure (3) du profilé (2). Ici le ruban (8) est de préférence réalisé en élastomère ou en PVC souple. Fig. 5 shows a variant of the solution for folded sheet metal profiles (2) whose mounting tape (8) covers the groove (3) with its outer part (13) wider than the opening (34) of said groove (3). The ribbon also comprises anchoring elements (14) locking it under the heels (31) of the groove (3) of the profile (2). Here the ribbon (8) is preferably made of elastomer or flexible PVC.

Fig. 6 montre une solution dont le ruban de montage (8) comporte des ouvertures (7) à diamètre réduit dans la partie inférieure (19). L'introduction des tiges (5) du grillage (4) provoque un écartement de la partie inférieure du ruban (8) le verrouillant ainsi dans le profilé (2) réalisé ici en tôle pliée (22). Fig. 6 shows a solution whose mounting tape (8) has openings (7) with reduced diameter in the lower part (19). The introduction of the rods (5) of the mesh (4) causes a spacing of the lower portion of the ribbon (8) thereby locking it in the profile (2) here made of folded sheet (22).

Fig. 7 montre une version du ruban (8), ici en forme de U réalisé de préférence en PVC souple ou élastomère dur verrouillé sous le talon (31) du profilé (2). Fig. 7 shows a version of the ribbon (8), here U-shaped preferably made of flexible PVC or hard elastomer locked under the heel (31) of the profile (2).

Fig. 8 montre un profilé (2) dont un talon (23) à l'intérieur de la rainure (3) réduit sa largeur (16) à une largeur (17) créant ainsi une déformation (141) pour 50 empêcher le ruban (8) de sortir de la rainure (3). Fig. 8 shows a profile (2) with a bead (23) inside the groove (3) reducing its width (16) to a width (17) thereby creating a deformation (141) to prevent the tape (8). to leave the groove (3).

Fig. 9 montre le cas général de Fig. 3, 4, 6, 7 et 8 caractérisé par le fait que la face extérieure (10;11) du ruban (8) constitue la prolongation de la face extérieure (12) du profilé (2), contrairement à la solution montrée sur Fig. 5 ou la face extérieure (12) du profilé (2) est capotée par la partie extérieure (13) à la rainure (3) du ruban de fermeture (8). Fig. 9 shows the general case of FIG. 3, 4, 6, 7 and 8 characterized in that the outer face (10; 11) of the ribbon (8) constitutes the extension of the outer face (12) of the profile (2), unlike the solution shown in FIG. . 5 or the outer face (12) of the profile (2) is covered by the outer portion (13) to the groove (3) of the closure tape (8).
