Description
Bande profilée en forme de pince montée sur le bord d'un élément notamment de carrosserie automobile
La présente invention a pour objet une bande profilée en forme de pince montée sur le bord d'un élément notamment-de carrosserie automobile.Profiled strip in the shape of a clamp mounted on the edge of an element, in particular of automobile bodywork
The present invention relates to a profiled strip in the form of a clamp mounted on the edge of an element in particular of automobile bodywork.
I1 est connu de réaliser des bandes de joint pour fenêtres, glaces ou portes,notamment dans les véhicules, constituées par des profilés en élastomère ou autre matière analogue, qui ont la forme d'un U dont les deux branches portent sur leurs faces intérieures des lèvres de maintien et qui peuvent être enfoncées sur le bord ou collet de l'élément de carrosserie. I1 is known to produce joint strips for windows, windows or doors, in particular in vehicles, formed by profiles of elastomer or other similar material, which have the shape of a U, the two branches of which bear on their inner faces holding lips and which can be pressed into the edge or collar of the bodywork element.
Toutefois, les constructeurs de véhicules exigent que ces bandes profilées en forme de pince soient engagées sur le bord de l'élément de carrosserie avec un minimum d'effort et présentent une grande résistance à l'arrachement. Or, jusqu'à présent l'effet demandé est obtenu en réalisant des bandes profilées présentant des dimensions très précises qu'il est très difficile de respecter, de telle sorte que ces bandes profilées ne présentent pas toujours les qualités permettant d'obtenir l'effet demandé. However, vehicle manufacturers require that these profiled clamp-shaped bands be engaged on the edge of the body element with a minimum of effort and have a high resistance to tearing. However, so far the requested effect is obtained by producing profiled strips having very precise dimensions which it is very difficult to comply with, so that these profiled strips do not always have the qualities enabling the effect requested.
La présente invention a pour objet de remédier à cet inconvénient. Conformément à la présente demande, au moins l'une des branches de la bande délimitant la rainure comporte sur sa face intérieure une lèvre et une contre-lèvre, ladite lèvre étant solidaire de ladite branche à proximité de l'entrée de la rainure et s'étendant en direction du fond de la rainure, de telle sorte que ladite lèvre vienne s'arc-bouter par son bord libre sur la contre-lèvre qui est située à proximité du fond de la rainure, lorsque le bord de l'élément est engagé dans la rainure et comprime ladite lèvre qui est ainsi verrouillée sur la contre-lèvre. The object of the present invention is to remedy this drawback. In accordance with the present application, at least one of the branches of the strip delimiting the groove has on its inner face a lip and a counter lip, said lip being integral with said branch near the entrance to the groove and s 'extending towards the bottom of the groove, so that said lip comes to brace by its free edge on the counter lip which is located near the bottom of the groove, when the edge of the element is engaged in the groove and compresses said lip which is thus locked on the counter lip.
Cette disposition permet au montage l'introduction du bord de l'élément dans la rainure de la bande profilée avec un minimum d'effort car la lèvre peu épaisse et déjà orientée s'aplatit. This arrangement allows mounting the introduction of the edge of the element in the groove of the profiled strip with a minimum of effort because the thin lip and already oriented flattens.
Par contre, le dégrafage de la bande profilée est pratiquement impossible sauf en exerçant de gros efforts, du fait que la lèvre est verrouillée sur la contre-lèvre et qu'il en résulte un frottement important entre la lèvre et le bord de l'élément de carrosserie. On the other hand, the unclipping of the profiled strip is practically impossible except by exerting great efforts, owing to the fact that the lip is locked on the counter-lip and that this results in significant friction between the lip and the edge of the element. of bodywork.
La grande résistance à l'arrachement résulte uniquement du coefficient de frottement, sans avoir à faire appel à un effet mécanique. The high pull-out resistance results solely from the friction coefficient, without having to use a mechanical effect.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un mode de réalisation et en se référant aux dessins annexés, sur lesquels
la figure 1 est une vue en coupe transversale d'un mode de réalisation d'une bande profilée avant son montage sur le bord d'un élément de carrosserie ;
la figure 2 est une même vue de la bande profilée pendant son montage sur le bord d'un élément de carrosserie
la figure 3 est une même vue de la bande profilée lorsqu'une traction est exercée sur le bord de l'élément.Other characteristics and advantages of the invention will be better understood on reading the following description of an embodiment and with reference to the accompanying drawings, in which
Figure 1 is a cross-sectional view of an embodiment of a profiled strip before it is mounted on the edge of a bodywork element;
Figure 2 is a same view of the profiled strip during its assembly on the edge of a bodywork element
Figure 3 is the same view of the profiled strip when traction is exerted on the edge of the element.
Aux figures 1, 2 et 3, on a représenté un mode de réalisation d'une bande profilée qui est réalisée notamment en élastomère et qui présente en section la forme d'un U dont les branches 1, la et le fond 2 délimitent intérieurement une rainure 3 dans laquelle est susceptible d'entre engagé un bord 4 d'un élément notamment de çarrosserie automobile. In Figures 1, 2 and 3, there is shown an embodiment of a profiled strip which is made in particular of elastomer and which has in section the shape of a U whose branches 1, la and the bottom 2 internally define a groove 3 in which an edge 4 is capable of engaging an element, in particular of an automobile bodywork.
Dans la paroi en élastomère de la bande profilée est noyé un organe de renfort métallique 5 qui affecte également la forme d'un U. Au moins l'une des branches 1 de la bande comporte sur sa face intérieure 6 une lèvre 7 et une contre-lèvre 8. In the elastomer wall of the profiled strip is embedded a metal reinforcing member 5 which also has the shape of a U. At least one of the branches 1 of the strip has on its inner face 6 a lip 7 and a counter - lip 8.
La lèvre 7 est solidaire de la branche l à proximité de l'entrée de la rainure 3 et s'étend en direction du fond 3a de la rainure. La lèvre 7 présente avant son montage (figure 1) une première partie 7a légèrement inclinée vers l'intérieur de la rainure et qui est prolongée par une deuxième partie 7b plus effilée et plus inclinée s'étendant sensiblement parallèlement aux branches 1, la de la bande profilée. La deuxième partie 7b présente à son extrémité un bord recourbé 7c formant un crochet susceptible de venir s'engager sur l'extrémité de la contre-lèvre 8. The lip 7 is integral with the branch l near the entrance to the groove 3 and extends towards the bottom 3a of the groove. The lip 7 has before its mounting (Figure 1) a first part 7a slightly inclined towards the inside of the groove and which is extended by a second part 7b more tapered and more inclined extending substantially parallel to the branches 1, the of the profiled strip. The second part 7b has at its end a curved edge 7c forming a hook capable of coming to engage on the end of the counter lip 8.
La contre-lèvre 8 est située à proximité du fond 3a de la rainure 3 et elle est inclinée en direction dudit fond 3a. Against the lip 8 is located near the bottom 3a of the groove 3 and it is inclined in the direction of said bottom 3a.
Lorsqu'on engage le bord 4 de l'élément en direction de la rainure 3 de la bande profilée (figure 1), celui-ci rencontre tout d'abord la partie 7b de la lèvre 7 qu'il comprime contre la contre-lèvre 8 ainsi qu'il est représenté à la figure 2.When the edge 4 of the element is engaged in the direction of the groove 3 of the profiled strip (FIG. 1), the latter first meets the part 7b of the lip 7 which it compresses against the counter lip 8 as shown in FIG. 2.
Cette introduction s'effectue avec un minimum d'effort car la lèvre 7 a tendance à se recourber autour de sa partie 7a sans opposer de résistance importante. This introduction is carried out with a minimum of effort because the lip 7 tends to curl around its part 7a without opposing significant resistance.
Par contre, si on exerce une traction sur le bord 4 de l'élément suivant la flèche Fl ou inversement sur la bande profilée (figure 3), le bord recourbé 7c de la lève 7 vient s'arcbouter sur la contre-lèvre 8 et se trouve ainsi en position de verrouillage. On the other hand, if a traction is exerted on the edge 4 of the element according to the arrow F1 or vice versa on the profiled strip (FIG. 3), the curved edge 7c of the lifter 7 comes to be arched on the counter lip 8 and is thus in the locked position.
Le bord 4 de l'élément est ainsi maintenu entre la face intérieure de la branche la et la partie 7b de la lèvre 7. The edge 4 of the element is thus maintained between the inner face of the branch 1a and the part 7b of the lip 7.
il en résulte une grande force de frottement contre les faces du bord 4 qui nécessite pour son arrachement un effort très important pouvant aboutir à la destruction de la lèvre 7. this results in a great force of friction against the faces of the edge 4 which requires for its tearing off a very significant force which can lead to the destruction of the lip 7.
Bien entendu, l'invention n'est pas limitative et l'homme de l'art pourra y apporter des modifications sans sortir pour cela du domaine de l'invention. Of course, the invention is not limiting and those skilled in the art may make modifications to it without departing from the scope of the invention.
