Description
ARMATURE POUR JOINT D'ETANCHE1TE. FRAME FOR SEALING GASKET 1TE.
La présente invention concerne une armature pour joint d'étanchéité et notamment pour joint d'étanchéité de véhicule automobile. The present invention relates to a frame for a seal and in particular for a seal for a motor vehicle.
1l existe déjà des armatures métalliques comprenant une succession d'éléments rectangulaires parallèles reliés latéralement par au moins un pont ou entretoise pour former une bande longitudinale continue. There are already metallic reinforcements comprising a succession of parallel rectangular elements connected laterally by at least one bridge or spacer to form a continuous longitudinal strip.
Cependant, dans certaines applications, on recherche un comportement mécanique bien déterminé du joint qui ne peut être obtenu avec les armatures précédentes. C'est notamment le cas lorsqu'on veut produire un joint déformable dans toutes les directions et surtout compressible dans le sens longitudinal avec une armature à pliages multiples. However, in certain applications, a well-determined mechanical behavior of the joint is sought which cannot be obtained with the preceding reinforcements. This is particularly the case when it is desired to produce a deformable joint in all directions and above all compressible in the longitudinal direction with a frame with multiple folds.
Ce but est atteint par l'invention pour la première fois et de manière satisfaisante au moyen d'une armature pour joint d'étanchéité comprenant une succession d'éléments rectangulaires plats et parallèles reliés latéralement par au moins un pont pour former une bande longitudinale continue, caractérisée en ce qu'elle comporte deux séries de ponts, les ponts de chacune des deux séries étant alternativement disposés de part et d'autre de l'axe longitudinal de la bande ; les ponts de la première série étant situés aux extrémités latérales des éléments rectangulaires et les ponts de la seconde série étant situés à proximité de l'axe longitudinal. This object is achieved by the invention for the first time and in a satisfactory manner by means of a frame for a gasket comprising a succession of rectangular flat and parallel elements connected laterally by at least one bridge to form a continuous longitudinal strip. , characterized in that it comprises two series of bridges, the bridges of each of the two series being alternately arranged on either side of the longitudinal axis of the strip; the bridges of the first series being located at the lateral ends of the rectangular elements and the bridges of the second series being located near the longitudinal axis.
Selon une variante de réalisation, les ponts sont conformés de telle sorte qu'ils définissent une bande ajourée dont les découpes s'étendent dans le sens transversal et sont à bords arrondis. According to an alternative embodiment, the bridges are shaped so that they define an openwork strip whose cutouts extend in the transverse direction and are with rounded edges.
Selon une autre variante, les ponts sont conformés de telle sorte qu'ils définissent une bande fentée dont les fentes s'étendent dans le sens transversal. According to another variant, the bridges are shaped so that they define a slotted strip whose slits extend in the transverse direction.
Un autre objet de l'invention est un procédé de fabrication d'un joint d'étanchéité par utilisation de Armature précédente, caractérisé en ce qu'il comprend, successivement, le pliage au niveau des ponts de la seconde série respectivement dans un sens pour les ponts situés du même côté de l'axe longitudinal en formant un coude en U dont la largeur correspond sensiblement à celle desdits ponts et dans l'autre sens pour les ponts situés de l'autre côté dudit axe en formant un pli à 180' définissant une branche latérale plus longue conformée en équerre puis l'enrobage de l'armature par un matériau élastomère. Another object of the invention is a method of manufacturing a seal by using the preceding frame, characterized in that it comprises, successively, folding at the level of the bridges of the second series respectively in one direction for bridges located on the same side of the longitudinal axis by forming a U-shaped bend whose width corresponds substantially to that of said bridges and in the other direction for bridges located on the other side of said axis by forming a fold at 180 ' defining a longer lateral branch shaped as a square and then coating the frame with an elastomeric material.
Selon une caractéristique du procédé de l'invention, on réalise les ponts (3b,3'b) de la seconde série en des positions et avec des dimensions déterminées en fonction du nombre et des caractéristiques des pliages envisagés. According to a characteristic of the process of the invention, the bridges (3b, 3'b) of the second series are produced in positions and with dimensions determined according to the number and characteristics of the folds envisaged.
L'armature de l'invention permet d'obtenir un profilage à pliages multiples susceptible d'être monté sur un support qui n'est ni plat, ni rectiligne et sans usinage préalable. The frame of the invention makes it possible to obtain profiling with multiple folds capable of being mounted on a support which is neither flat nor straight and without prior machining.
De plus, l'armature de l'invention a une bonne compressibilité longitudinale permettant d'assurer un contact intime et permanent à la liaison d'extrémité entre le joint qui la contient et les joints adjacents. In addition, the reinforcement of the invention has good longitudinal compressibility making it possible to ensure intimate and permanent contact at the end link between the joint which contains it and the adjacent joints.
L'invention sera mieux comprise à la lecture de la description qui va suivre, accompagnée des dessins annexés, sur lesquels;
- les figures la, lob et 2 représentent trois modes de réalisation de l'invention en vue de dessus à l'état plan ; et,
- la figure 3 représente une vue latérale en coupe d'un joint d'étanchéité comportant l'armature de l'invention.The invention will be better understood on reading the description which follows, accompanied by the appended drawings, in which;
- Figures la, lob and 2 show three embodiments of the invention in top view in the planar state; and,
- Figure 3 shows a side sectional view of a seal comprising the frame of the invention.
L'armature 1 représentée sur les figures la et lb est réalisée en matérieu résistant (métal....). Elle comprend une succession d'éléments rectangulaires plats 2, parallèles entre-eux et reliés latéralement par des ponts ou entretoises 3 pour former une bande longitudinale continue. The frame 1 shown in Figures la and lb is made of resistant material (metal ....). It comprises a succession of flat rectangular elements 2, mutually parallel and connected laterally by bridges or spacers 3 to form a continuous longitudinal strip.
Les ponts 3 sont répartis en deux séries (3a,3b), les ponts de chacune des deux séries étant disposés alternativement de part et d'autre de l'axe longitudinal
X de la bande.The bridges 3 are divided into two series (3a, 3b), the bridges of each of the two series being arranged alternately on either side of the longitudinal axis
X of the strip.
Ainsi, les ponts 3a de la première série sont situés aux extrémités latérales des éléments rectangulaires 2, alternativement d'un côté et de l'autre de la bande. Thus, the bridges 3a of the first series are located at the lateral ends of the rectangular elements 2, alternately on one side and the other of the strip.
De même, les ponts 3b de la seconde série sont situés, à l'intérieur de la bande, à proximité de l'axe longitudinal X, alternativement d'un côté (ponts 3b) et de l'autre (ponts 3'b), de façon symétrique sur la figure la et asymétrique sur la figure lb.. Similarly, the bridges 3b of the second series are located, inside the strip, near the longitudinal axis X, alternately on one side (bridges 3b) and on the other (bridges 3'b) , symmetrically in Figure la and asymmetric in Figure lb ..
De cette façon, les ponts 3a,3b,3'b définissent entre les éléments rectangulaires 2 des découpes s'étendant perpendiculairement à l'axe X en formant ainsi une bande ajourée avec des découpes 4 à bords internes arrondis. In this way, the bridges 3a, 3b, 3'b define between the rectangular elements 2 cutouts extending perpendicular to the axis X thereby forming an openwork strip with cutouts 4 with rounded internal edges.
Les découpes sont donc réparties entre des découpes à contours fermés 4a et des découpes à contours ouverts 4b débouchant sur les bords latéraux de la bande. The cutouts are therefore distributed between cuttings with closed contours 4a and cuttings with open contours 4b opening onto the lateral edges of the strip.
L'armature représentée sur la figure 2 reprend la même structure que celle illustrée sur la figure 1 mais la bande est fentée dans le sens transversal et les fentes 5a,5b remplacent alors les découpes 4a,4b. The frame shown in Figure 2 has the same structure as that illustrated in Figure 1 but the strip is slotted in the transverse direction and the slots 5a, 5b then replace the cutouts 4a, 4b.
Le joint 10 représenté sur Ia figure 3 comporte l'armature 1 de l'invention. The seal 10 shown in FIG. 3 comprises the frame 1 of the invention.
Ce joint est fabriqué en pliant au préalable l'armature 1 au niveau des ponts 3b de la seconde série respectivement dans un premier sens pour les ponts 3b situés du même côté de l'axe longitudinal X en formant un coude 13 en U dont la largeur correspond sensiblement à celle des ponts 3b. This joint is produced by folding beforehand the reinforcement 1 at the level of the bridges 3b of the second series respectively in a first direction for the bridges 3b situated on the same side of the longitudinal axis X by forming a bend 13 in U whose width corresponds substantially to that of bridges 3b.
Les ponts 3b' situés de l'autre côté de l'axe X sont pliés dans l'autre sens pour former un pli serré 33 à 180 en définissant ainsi une branche plus longue conformée en équerre 6. The bridges 3b ′ located on the other side of the axis X are folded in the other direction to form a tight fold 33 to 180, thus defining a longer branch shaped as a square 6.
La partie verticale de la branche en équerre 6 est quasiment au contact de la branche verticale adjacente du coude 13 en U. The vertical part of the angled branch 6 is almost in contact with the adjacent vertical branch of the U-shaped elbow 13.
Une fois pliée de la sorte, l'armature est enrobée de manière connue dans un matériau élastomère pour former le joint 10 dont le coude 13 en U forme la pince de fixation sur la carrosserie d'un véhicule. Once folded in this way, the frame is coated in a known manner in an elastomeric material to form the seal 10 whose elbow 13 in U forms the clamp for fixing to the body of a vehicle.
Selon l'invention, il est prévu que les ponts (3b,3'b) soient réalisés en des positions avec des dimensions prédéterminées en fonction du nombre et des caractéristiques des pliages envisagés. According to the invention, it is provided that the bridges (3b, 3'b) are made in positions with predetermined dimensions depending on the number and characteristics of the envisaged folds.
La branche en équerre 6 constitue un moyen de retenue du joint 10 sur une autre partie du véhicule telle qu'une garniture intérieure de porte. The angled branch 6 constitutes a means of retaining the seal 10 on another part of the vehicle such as an interior door trim.
