SYSTEME DE FIXATION DE FAUSSE PAROI AVEC LANGUETTEFALSE MOUNTING SYSTEM WITH TAB
RENFORCEE ENHANCED
La présente invention concerne le domaine des fausses parois telles que les faux plafonds et les faux murs et en particulier ceux constitués par une nappe souple tendue accrochée le long de ses bords à un support fixé aux murs ou au plafond d'une pièce d'un bâtiment. The present invention relates to the field of false walls such as false ceilings and false walls and in particular those constituted by a stretched flexible sheet hung along its edges to a support fixed to the walls or the ceiling of a room of a building.
Les fausses parois connues reposent sur le principe d'une mise sous tension de la nappe souple sur le cadre formé par des lisses aboutées, de manière parfaitement plane, horizontalement ou verticalement selon qu'il s'agisse d'un faux plafond ou d'un faux mur. Known false walls are based on the principle of a power of the flexible web on the frame formed by abutting smooth, perfectly flat, horizontally or vertically depending on whether it is a false ceiling or a false wall.
Ces faux plafonds ou faux murs, une fois montés sur leurs lisses laissent nécessairement apparaître un jeu souvent important et donc visible entre la périphérie de la paroi tendue et les murs supportant les lisses d'accrochage. Ce jeu fonctionnel résulte obligatoirement de la nécessité de prévoir un espace intercalaire suffisant entre le mur et la surface tendue pour insérer les crochets périphériques de la nappe en forme de harpon à l'intérieur des lisses de telle façon que le bourrelet d'extrémité du harpon vienne reposer sur un épaulement prévu à cet effet sur l'aile externe de la lisse la plus proche du mur conformément à ce qui est représenté en figure 1 par exemple. These false ceilings or false walls, once mounted on their smooth necessarily leave a game often prominent and therefore visible between the periphery of the wall tension and the walls supporting the stringers. This functional clearance necessarily results from the need to provide sufficient space between the wall and the tensioned surface to insert the peripheral hooks of the harpoon-shaped web inside the smooth so that the end cap of the harpoon come rest on a shoulder provided for this purpose on the outer flange of the rail closest to the wall in accordance with what is shown in Figure 1 for example.
Toutefois, dans de nombreux cas, cet espace résiduel entre "la nappe et le mur peut être visuellement gênant car il constitue un joint creux donnant une impression parfois très inesthétique. Il peut être, en outre, source de passages d' air intempestifs générateurs de salissures ou susceptibles de déséquilibrer certaines installations d'aération. However, in many cases this residual space between the ply and the wall can be visually troublesome because it constitutes a hollow joint giving a sometimes very unsightly impression, and can also be a source of untimely air passages generating dirt or likely to unbalance some aeration systems.
Pour pallier ces inconvénients, on connaît déjà notamment par la demande internationale de brevet PCT/FR2009/000021 au nom de NORMALU, un système de fixation de fausses parois tendues conforme à la figure 1, lesdites fausses parois étant constituées d'une nappe souple accrochée par ses bordures à un cadre fixé au mur ou au plafond d'une pièce, ledit cadre étant constitué par une lisse de taille réduite formée de profils aboutés comprenant au moins deux ailes avantageusement parallèles dont l'une, dite externe, comporte d'un côté des moyens de fixation au mur ou au plafond et présente de l'autre côté un épaulement s' étendant perpendiculairement vers l'intérieur de la lisse en direction de la pièce et dont l'autre, dite interne, est reliée à la première par une âme située à l'une de ses extrémités et s'étend à l'autre extrémité un peu au-delà de l' épaulement de la première aile pour former l'appui périphérique de la nappe qui est tendue sensiblement perpendiculairement à l'aile interne grâce à ses bordures munies d' un harpon inséré à la manière d'un «col de cygne» entre les deux ailes de la lisse et formé d'une première section reliée à la nappe et d'une deuxième section repliée sur la première dont le bourrelet d'extrémité vient en appui sur l' épaulement de l'aile externe. Le système est tel que ledit bourrelet d'extrémité du harpon comporte une lèvre de décrochage issue perpendiculairement de la zone d'appui dudit bourrelet sur 1' épaulement et s' étendant sous ledit épaulement dans l'interstice compris entre celui-ci et l'aile interne de la lisse de telle façon que ladite lèvre serve de levier pour un outil de dépose, permettant de repousser hors de 1' épaulement le bourrelet d'extrémité du harpon, sans pénétration de l'outil dans la lisse, pour démonter aisément la nappe de son cadre. To overcome these disadvantages, we already know in particular by the international patent application PCT / FR2009 / 000021 in the name of NORMALU, a false wall tensioning system according to FIG. 1, said false walls being constituted by a flexible sheet hung by its borders to a frame fixed to wall or ceiling of a room, said frame being constituted by a reduced-size smooth formed of abutting profiles comprising at least two preferably parallel wings, one of which, said external, comprises on one side means of attachment to the wall or to the ceiling and has on the other side a shoulder extending perpendicularly towards the inside of the rail in the direction of the room and the other, said internal, is connected to the first by a soul located at one of its ends and extends at the other end a little beyond the shoulder of the first wing to form the peripheral support of the sheet which is stretched substantially perpendicular to the inner wing through at its edges provided with a harpoon inserted in the manner of a "gooseneck" between the two wings of the rail and formed of a first section connected to the web and a second section folded over the first one of which the end bead bears against the shoulder of the outer wing. The system is such that said end bead of the harpoon comprises a stall lip issuing perpendicularly from the bearing zone of said bead on one shoulder and extending under said shoulder in the gap between it and the shoulder. internal wing of the bar so that said lip serves as a lever for a removal tool, for pushing out of one shoulder the bead end of the harpoon, without penetration of the tool in the bar, to easily remove the tablecloth of its frame.
Ladite demande internationale divulgue également une variante particulièrement avantageuse représentée sur la figure 2, selon laquelle, l'épaulement prévu sur l'aile externe pour servir d' appui au bourrelet d' extrémité du harpon, est remplacé par une entaille pratiquée dans l'épaisseur de l'aile externe de la lisse pour servir de zone d'appui audit bourrelet d'extrémité du harpon. De préférence, l'entaille a une forme générale de triangle rectangle dont le petit côté de l'angle droit, perpendiculaire au plan de l'aile externe de la lisse, dans une configuration dénommée «mini-lisse», sert d'appui au bourrelet d'extrémité du harpon et dont l'hypoténuse facilite l'engagement du bourrelet du harpon au moment du montage de la toile. Said international application also discloses a particularly advantageous variant represented on the 2, according to which, the shoulder provided on the outer flange to support the end flange of the harpoon, is replaced by a cut made in the thickness of the outer wing of the beam to serve as a zone. supporting said end cap of the harpoon. Preferably, the notch has a general shape of a right triangle whose small side of the right angle, perpendicular to the plane of the outer wing of the beam, in a configuration called "mini-smooth", serves as a support for end cap of the harpoon and whose hypotenuse facilitates the engagement of the bead of the harpoon at the time of assembly of the canvas.
Toutefois, compte tenu de la forme de l'épaulement, lorsqu'on utilise l'outil de dépose par exemple pour sortir le harpon de la mini-lisse en prenant appui sur la lèvre de décrochage, on ne peut appuyer que sur la partie de ladite lèvre la plus extrême et donc la plus flexible. Il en résulte que très souvent la lèvre se déforme sans provoquer un repoussement suffisant de ladite lèvre contre l'aile de liaison du harpon à la nappe pour décrocher la face radiale de la lèvre du harpon reposant sur l'épaulement de la minilisse. Ce qui a pour effet de ne pas permettre l'extraction vers le bas du harpon et donc le décrochage la nappe. However, given the shape of the shoulder, when using the removal tool for example to remove the harpoon of the mini-boom by pressing on the stall lip, you can only press the part of said lip is the most extreme and therefore the most flexible. It follows that very often the lip deforms without causing sufficient repulsion of said lip against the harpoon connecting wing to the web to unhook the radial face of the harpoon lip resting on the shoulder of the minilisse. This has the effect of not allowing the extraction to the bottom of the harpoon and therefore the stall the tablecloth.
La présente invention a donc pour but de pallier de tels inconvénients en proposant un système de fixation d'une paroi tendue, par exemple un plafond entre deux murs permettant à la fois d'avoir, après montage dudit plafond, un jeu résiduel très faible entre la nappe et le mur et de garantir un montage ou démontage aisé. The present invention therefore aims to overcome such drawbacks by proposing a fastening system of a stretched wall, for example a ceiling between two walls for both having, after mounting said ceiling, a very small residual clearance between the tablecloth and the wall and guarantee easy assembly or disassembly.
Conformément à l'invention, il est ainsi proposé un système de fixation de fausses parois tendues, constituées d' une nappe souple accrochée par ses bordures à un cadre fixé au mur ou au plafond d'une pièce, ledit cadre étant constitué par une lisse formée de profils aboutés - A - comprenant au moins deux ailes avantageusement parallèles dont l'une, dite externe, comporte d'un côté des moyens de fixation au mur ou au plafond et présente de l'autre côté un épaulement s' étendant perpendiculairement vers l'intérieur de la lisse en direction de la pièce et dont l'autre, dite interne, est reliée à la première par une âme située à l'une de ses extrémités et s'étend à l'autre extrémité un peu au-delà de l' épaulement de la première aile pour former l'appui périphérique de la nappe qui est tendue sensiblement perpendiculairement à l'aile interne grâce à ses bordures munies d'un harpon formé d'une branche interne par laquelle il est relié à la nappe et d'une branche externe repliée sur la première dont le bourrelet d'extrémité vient en appui sur l' épaulement de l'aile externe, ledit harpon comporte une lèvre de décrochage s' étendant sous ledit épaulement dans l'interstice compris entre celui-ci et l'aile interne de la lisse ; ledit système de fixation est remarquable en ce que la lèvre de décrochage est une pièce renforcée présentant notamment une rigidité supérieure par rapport aux autres parties du harpon et permettant un démontage efficace de la nappe. According to the invention, it is thus proposed a fastening system false strained walls, consisting of a flexible sheet hung by its borders to a frame attached to the wall or the ceiling of a room, said frame being constituted by a smooth formed of butted profiles - A - comprising at least two advantageously parallel wings, one of which, said external, comprises on one side wall or ceiling fixing means and has on the other side a shoulder extending perpendicularly to the inside of the smooth in the direction of the room and the other, said internal, is connected to the first by a soul located at one of its ends and extends to the other end a little beyond the shoulder of the first wing to form the peripheral support of the sheet which is stretched substantially perpendicular to the inner wing by virtue of its edges provided with a harpoon formed by an inner branch by which it is connected to the sheet and a outer branch folded over the first of which the end rim bears on the shoulder of the outer flange, said harpoon has a stall lip extending under said shoulder in the gap between it and the shoulder; internal wing of the li sse; said fixing system is remarkable in that the stall lip is a reinforced piece having in particular a higher rigidity compared to other parts of the harpoon and allowing effective disassembly of the sheet.
On comprend bien qu'en utilisant un type de harpon conforme à l'invention, on augmente la rigidité de la lèvre de décrochage et on peut faire levier sur n' importe quelle partie de ladite lèvre de décrochage et permettre un repoussement plus efficace de ladite lèvre. It will be understood that by using a type of harpoon in accordance with the invention, the rigidity of the stall lip is increased and any part of said stall lip can be levered and allow a more efficient repulsion of said stall lip. lip.
D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre d'une variante d'exécution du système de fixation selon l'invention en référence aux figures annexées sur lesquelles : Other advantages and features will become more apparent from the following description of an alternative embodiment of the fastening system according to the invention with reference to the appended figures in which:
- la figure 1 est une vue en coupe verticale partielle d'un faux plafond constitué par une nappe tendue, et comportant une première variante de lisse fixée à la partie supérieure d'un mur d'une pièce selon l'art antérieur ; FIG. 1 is a partial vertical sectional view of a false ceiling constituted by a stretched sheet, and comprising a first variant of a rail attached to the upper part of a wall of a room according to the art. previous;

- la figure 3 est une vue en coupe verticale d'un système de fixation conforme à l'invention, FIG. 3 is a vertical sectional view of a fastening system according to the invention,
- la figure 4 est une vue agrandie en coupe verticale du harpon d'un système de fixation conforme à l'invention. - Figure 4 is an enlarged vertical sectional view of the harpoon of a fastening system according to the invention.
La figure 1 représente la partie extrême d' un faux plafond suivant l'art antérieur, qui est constitué par une nappe 1 souple tendue horizontalement en dessous du plafond 2 d'une pièce. Cette nappe 1 est fixée le long de ses bords à un support constitué par une lisse horizontale 3, elle-même fixée à la partie supérieure d'un mur 4 de la pièce par des moyens appropriés, non représentés, tels que des vis. Cette lisse 3 comprend une aile verticale externe 5 qui s'étend parallèlement au mur 4 et à proximité immédiate de celui-ci. De cette aile verticale externe 5 est issu, à peu près à mi-hauteur, une âme horizontale supérieure 6 s' étendant sur une faible distance, par exemple de l'ordre de quelques millimètres, vers l'intérieur de la pièce. Cette âme 6 se prolonge, à son extrémité, par une aile verticale interne 7 s' étendant vers le bas un peu plus bas que l'aile externe 5 proche du mur 4, c'est-à-dire que l'aile verticale interne 7 est un peu plus haute que l'aile externe 5 de ladite lisse. Cette aile externe 5 présente, à son extrémité inférieure, un épaulement 8 s' étendant horizontalement vers l'intérieur de la pièce, sur une faible distance qui est inférieure à largeur de l'âme 6. Cet épaulement à l'équerre 8 présente avantageusement une extrémité arrondie. Figure 1 shows the end portion of a false ceiling according to the prior art, which is constituted by a flexible sheet 1 stretched horizontally below the ceiling 2 of a room. This sheet 1 is fixed along its edges to a support consisting of a horizontal rail 3, itself attached to the upper part of a wall 4 of the part by appropriate means, not shown, such as screws. This smooth 3 comprises an outer vertical flange 5 which extends parallel to the wall 4 and in the immediate vicinity thereof. This outer vertical wing 5 is derived, approximately halfway up, an upper horizontal core 6 extending over a small distance, for example of the order of a few millimeters, towards the interior of the room. This core 6 is extended, at its end, by an internal vertical wing 7 extending downwards a little lower than the outer wing 5 close to the wall 4, that is to say that the vertical vertical wing 7 is a little higher than the outer wing 5 of said rail. This outer flange 5 has, at its lower end, a shoulder 8 extending horizontally towards the interior of the part, over a short distance which is less than the width of the core 6. This shoulder 8 advantageously has a rounded end.
La partie inférieure de l'aile verticale externe 5, l'âme horizontale supérieure 6 et l'aile verticale interne 7 déterminent un évidement 9 ouvert vers le bas et dans lequel peut être engagé le harpon 10 de fixation soudé à la périphérie de la nappe souple tendue 1. The lower part of the outer vertical wing 5, the upper horizontal web 6 and the inner vertical wing 7 determine a recess 9 open downwards and in which can be engaged the fastening harness 10 welded to the periphery of the stretched flexible web 1.
Ce harpon 10 présente en section droite une forme de crochet s' étendant vers le mur 4 et ouvert vers le bas. Il comprend une branche interne 10a., par laquelle il est relié à la nappe 1, et une branche externe 10b en forme de bourrelet à l'extrémité arrondie, qui est recourbée vers le bas. Le harpon 10 prend appui, lorsque la nappe 1 est tendue, sur l'épaulement 8 par l'extrémité inférieure de sa branche externe 10b qui s'étend vers le bas. Compte tenu de la faible dimension de la lisse 3 et afin de faciliter le démontage de la nappe 1, le harpon 10 comporte à l'extrémité de la branche externe 10b une lèvre de décrochage 11, issue perpendiculairement de la zone du bourrelet d'extrémité venant en appui sur l'épaulement 8 ; cette lèvre 11 est telle qu'elle peut s'étendre sous ledit épaulement 8 dans l'interstice compris entre ledit épaulement 8 et l'aile verticale interne 7 de la lisse 3 de telle façon que la lèvre 11 puisse servir de levier pour un outil de dépose, par exemple une classique spatule, permettant de repousser hors de l'épaulement 8 le bourrelet d'extrémité du harpon 10 sans qu'il soit nécessaire de pénétrer ladite spatule dans la lisse 3 pour démonter aisément la nappe 1 de son cadre. This harpoon 10 has in cross section a form of hook extending towards the wall 4 and open downwards. It comprises an inner branch 10a., By which it is connected to the ply 1, and an outer branch 10b in the form of a bead at the rounded end, which is bent downwards. The harpoon 10 is supported, when the sheet 1 is stretched, on the shoulder 8 by the lower end of its outer branch 10b which extends downwards. Given the small size of the rail 3 and to facilitate disassembly of the web 1, the harpoon 10 comprises at the end of the outer branch 10b a stall lip 11, issuing perpendicularly from the end bead area bearing on the shoulder 8; this lip 11 is such that it can extend under said shoulder 8 in the gap between said shoulder 8 and the inner vertical wing 7 of the bar 3 so that the lip 11 can serve as a lever for a tool depositing, for example a conventional spatula, for pushing out of the shoulder 8 the end bead of the harpoon 10 without the need to penetrate said spatula in the smooth 3 to easily remove the sheet 1 of its frame.
En revanche pour le montage de la nappe 1 dans une lisse 3, on utilise traditionnellement une spatule, déjà utilisée dans l'art antérieur, en repoussant le harpon 10 à l'intérieur de l'espace 9 de la lisse 3 afin de venir encliqueter le bourrelet d'extrémité du harpon 10 sur l'épaulement 8 de l'aile 5 de la lisse 3. On the other hand, for the assembly of the sheet 1 in a rail 3, a spatula, already used in the prior art, is traditionally used by pushing the harpoon 10 inside the space 9 of the rail 3 in order to snap into place. the end bead of the harpoon 10 on the shoulder 8 of the wing 5 of the rail 3.
Selon une variante particulièrement avantageuse représentée sur la figure 2, l'épaulement 8 prévu sur l'aile externe 5 de la variante précédente pour servir d'appui au bourrelet d'extrémité du harpon 10, est remplacé par une entaille 12 pratiquée dans l'épaisseur de l'aile externe 5 de la lisse 3 pour servir de zone d'appui audit bourrelet d'extrémité du harpon 10. Avantageusement, l'entaille 12 a une forme générale de triangle rectangle dont le petit côté 12a_ de l'angle droit, perpendiculaire au plan de l'aile externe 5 de la lisse 3 sert d'appui au bourrelet d'extrémité du harpon 10 et dont l'hypoténuse 12b facilite l'engagement du bourrelet du harpon 10 au moment du montage de la nappe 1. According to a particularly advantageous variant shown in FIG. 2, the shoulder 8 provided on the outer wing 5 of the preceding variant to serve as a support for the end bead of the harpoon 10, is replaced by a notch 12 made in the thickness of the outer flange 5 of the arm 3 to serve as a zone of 10. Advantageously, the notch 12 has a general shape of a right triangle whose small side 12a_ of the right angle, perpendicular to the plane of the outer flange 5 of the beam 3 serves as supporting the end cap of the harpoon 10 and whose hypotenuse 12b facilitates the engagement of the bead of the harpoon 10 at the time of assembly of the sheet 1.
Toutefois, compte tenu de la forme de 1 ' épaulement 8, le démontage du harpon 10, en repoussant hors de l' épaulement 8 de la lisse 3 le bourrelet d'extrémité du harpon 10, est délicat car l'outil de dépose fait levier sur la partie extrême de la lèvre 11. En effet, cette partie, qui est la plus souple de la lèvre, se déforme sans permettre un repoussage suffisant du bourrelet d'extrémité du harpon 10 et donc le désengagement du harpon 10 de la lisse 3. However, in view of the shape of the shoulder 8, the dismounting of the harpoon 10, by pushing the end bead of the harpoon 10 out of the shoulder 8 of the heald 3, is difficult because the removal tool is levered on the extreme part of the lip 11. In fact, this part, which is the most flexible of the lip, is deformed without allowing sufficient embossing of the end cap of the harpoon 10 and therefore the disengagement of the harpoon 10 of the arm 3 .
Conformément à l'invention, les figures 3 et 4 représentent un système de fixation de fausses parois tendues, constituées d'une nappe 1 souple accrochée par ses bordures à un cadre fixé au mur ou au plafond d'une pièce. Ledit cadre étant constitué par une lisse 3 similaire à celle décrite précédemment. Ainsi, ladite lisse 3 comporte une aile verticale externe 5 et une âme horizontale 6 issue à peu près à la mi-hauteur de ladite aile verticale externe 5 et s' étendant sur une faible distance vers l'intérieur de la pièce. Cette âme 6 se prolonge, à son extrémité, par une aile verticale interne 7 s' étendant vers le bas un peu plus bas que l'aile externe 5. Cette aile externe 5 présente, à son extrémité inférieure, un épaulement 8. La partie inférieure de l'aile verticale externe 5, l'âme horizontale supérieure 6 et l'aile verticale interne 7 déterminent un évidement 9 ouvert vers le bas. In accordance with the invention, FIGS. 3 and 4 show a fastening system for false tensioned walls, constituted by a flexible sheet 1 hung by its borders to a frame fixed to the wall or to the ceiling of a room. Said frame being constituted by a smooth 3 similar to that described above. Thus, said smooth 3 comprises an outer vertical wing 5 and a horizontal core 6 issued approximately at the mid-height of said vertical vertical wing 5 and extending a short distance towards the interior of the room. This core 6 is extended, at its end, by an inner vertical wing 7 extending downward a little lower than the outer wing 5. This outer flange 5 has, at its lower end, a shoulder 8. The portion lower vertical wing external 5, the upper horizontal web 6 and the inner vertical wing 7 determine a recess 9 open downwards.
La nappe 1 souple tendue comporte un harpon 10 de fixation soudé à la périphérie de ladite nappe 1 ; ledit harpon 10 peut être engagé dans 1 ' évidement 9 pour maintenir la nappe 1 tendue sur le cadre. Le harpon 10 est identique à celui décrit précédemment et présente en section droite une forme de crochet s' étendant vers le mur 4 et ouvert vers le bas. Il comprend une branche interne 10a_ par laquelle il est relié à la nappe 1, une branche externe 10b en forme de bourrelet à l'extrémité arrondie, qui est recourbée vers le bas et une lèvre de décrochage 13 issue de l'extrémité de la branche externe 10b et s 'étendant perpendiculairement de la zone du bourrelet d'extrémité venant en appui sur l'épaulement 8. The stretched flexible ply 1 comprises a fastening harness 10 welded to the periphery of said ply 1; said harpoon 10 can be engaged in the recess 9 to maintain the web 1 stretched on the frame. The harpoon 10 is identical to that described above and has in cross section a hook shape extending towards the wall 4 and open downwards. It comprises an internal branch 10a_ through which it is connected to the ply 1, an outer branch 10b in the form of a bead at the rounded end, which is bent downwards and a stall lip 13 coming from the end of the branch 10b and extending perpendicularly from the zone of the end bead bearing on the shoulder 8.
Toutefois, pour permettre un démontage efficace de la nappe 1, la lèvre de décrochage 13, selon l'invention, se compose d' une pièce renforcée présentant notamment une rigidité supérieure par rapport aux autres parties du harpon 10. However, to allow effective disassembly of the sheet 1, the stall lip 13, according to the invention, consists of a reinforced piece having in particular a higher rigidity compared to the other parts of the harpoon 10.
De manière avantageuse, la lèvre de décrochage 13 est issue de matière avec les branches interne et externe 10a et 10b en prenant soin de modifier la densité de matière entre ladite lèvre de décrochage 13 et lesdites branches. La densité de matière de la lèvre de décrochage 13 est alors supérieure à celle des branches interne et externe 10a. et 10b. Advantageously, the stall lip 13 is made of material with the inner and outer legs 10a and 10b taking care to change the density of material between said stall lip 13 and said branches. The material density of the stall lip 13 is then greater than that of the inner and outer legs 10a. and 10b.
Selon une première variante de réalisation, la lèvre de décrochage 13 est réalisée dans une matière différente de celle des branches interne et externe 10a_ et 10b, les matières utilisées étant de préférence des matières plastiques. Ainsi, la matière utilisée pour obtenir ladite lèvre de décrochage 13 possède des caractéristiques supérieures, notamment une rigidité, à celle utilisée pour obtenir les branches interne et externe 10a et 10b. Toutefois, la lèvre de décrochage 13 et les branches interne et externe 10a. et 10b sont avantageusement réalisées lors de la même opération d'injection. According to a first variant embodiment, the stall lip 13 is made of a material different from that of the inner and outer legs 10a and 10b, the materials used being preferably plastics. Thus, the material used to obtain said stall lip 13 has characteristics higher, including rigidity, than that used to obtain the inner and outer branches 10a and 10b. However, the stall lip 13 and the inner and outer legs 10a. and 10b are advantageously performed during the same injection operation.
Selon une deuxième variante, la lèvre de décrochage 13 est une pièce renforcée rapportée et solidaire du coté intérieur de la branche externe 10b. On entend ici par coté intérieur le coté de la branche externe 10b qui fait face à la branche interne 10a. De manière avantageuse, la pièce renforcée est une plaque métallique insérée lors de la fabrication du harpon. Cette pièce pourra également être rajoutée après ladite fabrication du harpon puis solidarisée par collage ou par tout autre moyen de fixation équivalent. In a second variant, the stall lip 13 is a reinforced piece attached and secured to the inner side of the outer leg 10b. Here is meant by the inner side the side of the outer branch 10b which faces the inner branch 10a. Advantageously, the reinforced piece is a metal plate inserted during the manufacture of the harpoon. This piece may also be added after said manufacture of the harpoon and secured by gluing or by any other equivalent attachment means.
Ainsi avec le harpon 10 ainsi configuré, on comprend bien que l'outil de dépose peut prendre appui sur n'importe quelle partie de la lèvre de décrochage 13, ladite partie étant par nature plus rigide et donc moins flexible et permettant un repoussage efficace de la branche externe 10b et donc un désengagement du harpon 10 de la lisse 3. Thus with the harpoon 10 thus configured, it is well understood that the removal tool can bear on any part of the stall lip 13, said part being inherently more rigid and therefore less flexible and allowing an effective repoussage of the outer branch 10b and therefore a disengagement of the harpoon 10 of the rail 3.
En outre, on comprend bien que si la lèvre de décrochage 13 est suffisamment longue et rigide, on pourra envisager de déposer la nappe 1 à la main sans l'aide d'un outil de dépose. In addition, it is clear that if the stall lip 13 is sufficiently long and rigid, it may be envisaged to deposit the sheet 1 by hand without the aid of a removal tool.
De plus, l'épaulement 8 prévu sur l'aile verticale externe 5 pour servir d'appui au bourrelet d'extrémité du harpon 10, pourra être remplacé par une entaille 12 conforme à celle représentée sur la figure 2, pratiquée dans l'épaisseur de l'aile externe 5 de la lisse 3 pour servir de zone d'appui audit bourrelet d'extrémité du harpon 10 sans sortir du cadre de l'invention. In addition, the shoulder 8 provided on the outer vertical wing 5 to serve as a support for the end bead of the harpoon 10, may be replaced by a notch 12 according to that shown in Figure 2, made in the thickness the outer wing 5 of the beam 3 to serve as a support zone to said end bead of the harpoon 10 without departing from the scope of the invention.
Enfin, il va de soi que la présente invention, n'est pas limitée aux variantes d'exécution décrites, mais qu'elle peut être modifiée ou adaptée en fonction des besoins ou des exigences particulières, sans pour autant sortir du cadre de l'invention. Finally, it goes without saying that the present invention is not limited to the embodiments described, but it can be modified or adapted according to the needs or special requirements, without departing from the scope of the invention.
