Description

       

  "Elément d'étanchéité"

  
La présente invention a trait à un élément d'étanchéité, notamment destiné aux raccordements de tubes, aux articulations ou analogues.

  
Pour assurer l'étanchéité des raccords mobiles

  
entre tubes et également des articulations, l'on utilise en  général des bagues ou cordons de feutre, mais aussi des joints

  
de caoutchouc, des manchons en matière plastique et des 

  
cordons- ronds en,mousse de gomme. Les joints à feutre et à caoutchouc sont collés à l'intérieur ou à l'extérieur ou bien  <EMI ID=1.1> 

  
Dons le cas de pièces en matière plastique à fortes tolérances qu'il faut rendre étanches l'une par rapport à l'autre - par exemple dans les articulations des buses d'aspirateurs de poussière- les différences de dimensions des cordons ou bagues de feutre sont trop fortes pour assurer l'obturation et permettre par conséquent une bonne étanchéité.

  
L'invention vise à réaliser un élément d'étanchéité qui soit établi sous forme suffisamment souple de manière à compenser les tolérances de fabrication entre les pièces à relier l'une à l'autre, et qui cependant assure une bonne étanchéité. En outre l'effort nécessaire au déplacement de l'articulation tournante ou basculante doit être aussi faible que possible et demeurer constante dans tout le domaine des tolérances permises. 

  
A cet effet, suivant l'invention, l'une des deux pièces à relier l'une à l'autre de façon étanche comporte un joint fait de fibres artificielles dressées appliqué par le procédé de projection de fibres orientées connu dans la technique sous le nom de flocage. Ce joint est avantageusement constitué par un support souple dont une face est auto-adhésive ou encollée, tandis que sur l'autre sont disposées les fibres artificielles dressées.

  
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer.

  
Fig. 1 est une coupe du joint tournant.et basculant  <EMI ID=2.1> 

  
 <EMI ID=3.1> 

  
 <EMI ID=4.1> 

  
 <EMI ID=5.1> 

  
laire 1 et la partie basculante 2 solidaire de la tubulure correspondante 3, d'autre part entre cette partie 2 et le corps 4 de la buse. A cet effet l'on a prévu dans l'embout 1 des rainures périphériques 5 dans lesquelles est monté un élément d'étanchéité 6 qui, comme le montre fig. 2, comporte un support soude 7, sur lequel on a réparti par projection
(flocage) des fibres synthétiques dressées 8 comportant la hauteur nécessaire à l'étanchéité désirée. cette hauteur

  
des fibres 8 est prévue de façon à permettre un raccordement étanche optimal des pièces 1 et 3, ou respectivement 2 et 4, en tenant compte du domaine des tolérances. En d'autres termes, c'est de ces dernières que dépend la hauteur ou longueur des fibres 8 ainsi disposées.

  
Pour fixer l'élément d'étanchéité 6 dans les  rainures 5, la face inférieure du support souple 7 est prévue auto-adhésive ou bien elle est recouverte d'une couche de  colle 9. Ce support peut être fait en feuille plastique mince, en tissu, en papier ou en caoutchouc.

  
En vue d'empêcher tout déplacement axial entre l'embout 1 et la tubulure 3, on a inséré à la façon connue un jonc élastique plat 10.

  
La partie 2 est montée dans le corps 4 de façon à  pouvoir basculer autour d'un axe 11. On y a prévu également une rainure 12 dans laquelle -est collé ;un élément, d'étanchéité

  "Sealing element"

  
The present invention relates to a sealing element, in particular intended for pipe connections, joints or the like.

  
To ensure the tightness of movable fittings

  
between tubes and also joints, we generally use felt rings or cords, but also joints

  
rubber, plastic sleeves and

  
round cords, gum foam. The felt and rubber gaskets are glued inside or outside or <EMI ID = 1.1>

  
For example, in the case of plastic parts with strong tolerances that must be sealed against each other - for example in the joints of the nozzles of dust extractors - the differences in dimensions of the cords or felt rings are too strong to ensure the sealing and therefore allow a good seal.

  
The invention aims to produce a sealing element which is established in a sufficiently flexible form so as to compensate for the manufacturing tolerances between the parts to be connected to one another, and which nevertheless ensures good sealing. In addition, the force required to move the rotating or tilting joint must be as low as possible and remain constant throughout the range of the allowable tolerances.

  
For this purpose, according to the invention, one of the two parts to be connected to one another in a sealed manner comprises a joint made of upright artificial fibers applied by the method of projection of oriented fibers known in the art under the flocking name. This seal is advantageously constituted by a flexible support, one side of which is self-adhesive or glued, while on the other are arranged the upright artificial fibers.

  
The appended drawing, given by way of example, will make it possible to better understand the invention, the characteristics that it has and the advantages that it is likely to provide.

  
Fig. 1 is a cross section of the rotating and tilting joint <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
laire 1 and the tilting part 2 integral with the corresponding pipe 3, on the other hand between this part 2 and the body 4 of the nozzle. For this purpose, peripheral grooves 5 are provided in the end piece 1 in which a sealing element 6 is mounted which, as shown in FIG. 2, comprises a soda support 7, on which we have distributed by projection
(flocking) of the upright synthetic fibers 8 comprising the height necessary for the desired seal. this height

  
fibers 8 is provided so as to allow an optimum sealed connection of parts 1 and 3, or 2 and 4 respectively, taking into account the range of tolerances. In other words, it is on the latter that the height or length of the fibers 8 thus arranged depends.

  
To fix the sealing element 6 in the grooves 5, the underside of the flexible support 7 is provided with self-adhesive or it is covered with a layer of glue 9. This support can be made of thin plastic sheet, in fabric, paper or rubber.

  
In order to prevent any axial displacement between the end piece 1 and the tube 3, a flat elastic ring 10 has been inserted in the known manner.

  
Part 2 is mounted in the body 4 so as to be able to swing around an axis 11. There is also provided a groove 12 in which -is glued; a sealing element
