Description
La présente invention concerne un raccord métalliqueThe present invention relates to a metal fitting
pour relier un appareil ménager à une alimentation de gaz. to connect a household appliance to a gas supply.
Les appareils ménagers, tels que les réchauds de cuisine, sont en général reliés à la canalisation de gaz, ou à une bouteille de gaz comprimé, par l'intermédiaire d'un tuyau en caoutchouc renforcé, dont les extrémités sont placées à force sur des pièces mâles tubulaires respectives, Household appliances, such as kitchen stoves, are generally connected to the gas pipe, or to a cylinder of compressed gas, by means of a reinforced rubber hose, the ends of which are placed by force on respective tubular male parts,
constituant à une extrémité, la sortie sur ladite cana- constituting at one end, the outlet on said channel
lisation ou sur le réducteur de la bouteille de gaz et, or on the reducer of the gas cylinder and,
de l'autre côté, l'entrée sur l'appareil ménager. on the other side, the entrance to the household appliance.
La surface extérieure de chacune de ces pièces mâles tubulaires est généralement munie de nervures dentelées, annulaires qui s'engagent de manière étanche avec la surface intérieure sur ledit tuyau, l'extrémité de ce dernier étant, en général, serrée sur la pièce mâle tubulaire au moyen d'une pince extérieure qui assure une double fonction, premièrement, d'empêcher toute fuite The external surface of each of these tubular male parts is generally provided with annular, serrated ribs which engage in a sealed manner with the internal surface on said pipe, the end of the latter being, in general, clamped on the tubular male part. by means of an external clamp which performs a double function, firstly, to prevent any leakage
de gaz et, deuxièmement, d'empêcher le tuyau de se déta- gas and, second, to prevent the hose from detaching

tent un certain nombre d'inconvénients dus au fait que le caoutchouc dont ils sont faits, subit graduellement un processus de vieillissement naturel, aggravé par contact avec le gaz, qui conduit, au bout d'un temps have a number of disadvantages due to the fact that the rubber of which they are made, gradually undergoes a natural aging process, aggravated by contact with the gas, which leads, after a time
relativement court, à un durcissement des tuyaux eux-mêmes. relatively short, hardening of the pipes themselves.
Ce durcissement est particulièrement dangereux sur les sections du tuyau voisines des extrémités desdites pièces mâles tubulaires. Non seulement ces sections de tuyaux sont soumises à des tensions et au contact avec le qaz, mais elles sont également les seules soumises à des contraintes de tension et de flexion accidentelles quand l'appareil ménager est déplacé, par exemple pour les nettoyages, ce qui conduit à un étirage du tuyau de raccordement. Le but de la présente invention est de fournir un raccord pour relier un appareil ménager à une alimentation de gaz, qui ne comporte pratiquement aucun des inconvénients susmentionné, c'est-à-dire, d'abord, être sujet à un vieillissement essentiellement non naturel et une fois assemblé de ne pas avoir de points de haute contrainte capables de produire la rupture ou une fuite de gaz ultérieure. Pour atteindre ce but, la présente invention concerne donc un raccord métallique pour relier un appareil ménager à une alimentation de gaz caractérisé par le fait qu'il comprend un tuyau et un élément de raccordement tubulaire This hardening is particularly dangerous on the sections of the pipe close to the ends of said tubular male parts. These pipe sections are not only subjected to stresses and contact with the qaz, but they are also the only sections subjected to accidental tension and bending stresses when the household appliance is moved, for example for cleaning, which leads to a stretching of the connection pipe. The object of the present invention is to provide a connector for connecting a household appliance to a gas supply, which has practically none of the above-mentioned drawbacks, that is to say, first of all, being subject to essentially non-aging. natural and once assembled to have no high stress points capable of producing a rupture or a subsequent gas leak. To achieve this object, the present invention therefore relates to a metal connector for connecting a household appliance to a gas supply, characterized in that it comprises a pipe and a tubular connection element

On va maintenant décrire un agencement non limitatif de la présente invention, en se référant au dessin annexé sur lequel: la figure 1 représente une vue en perspective d'un appareil ménager relié à une source de gaz par l'intermédiaire d'un raccord selon la présente invention; la figure 2 montre une vue explosée et en tive. We will now describe a non-limiting arrangement of the present invention, with reference to the accompanying drawing in which: Figure 1 shows a perspective view of a household appliance connected to a gas source via a connector according to the present invention; Figure 2 shows an exploded view and

Comme représenté sur la figure 1, l'extrémité libre du tuyau 4 est relieéà une pièce mâle axiale tubulaire 5 alors qu'une pièce mâle tubulaire identique est reliée As shown in Figure 1, the free end of the pipe 4 is connected to a tubular axial male part 5 while an identical tubular male part is connected

Les éléments tubulaires 8 sont reliés ensemble par un tube métallique 9 ondulé et chacun d'eux comprend deux corps 10, 11 sensiblement en forme de coupe, leurs faces se faisant face. Les corps 10 et 11 comportent des parois latérales cylindriques respectives 12 et 13 ayant des The tubular elements 8 are connected together by a corrugated metal tube 9 and each of them comprises two bodies 10, 11 substantially in the form of a cup, their faces facing each other. The bodies 10 and 11 have respective cylindrical side walls 12 and 13 having
trous axiaux traversants 14 et 15.through axial holes 14 and 15.
Avec plus de détails, on voit que la paroi 12 sur le corps 10 présente une surface intérieure cylindrique munie d'un filetage 16 et reliée avec le trou 14 par une surface 17 en forme de tronc de cane B conicité dirigée vers l'extérieur, alors que la paroi 13 sur le corps 11 présente une surface extérieure cylindrique munie d'un filetage 18 qui s'engage de manière réglable avec un filetage 16 et qui se termine intérieurement With more details, it can be seen that the wall 12 on the body 10 has a cylindrical interior surface provided with a thread 16 and connected with the hole 14 by a surface 17 in the form of a cane trunk B with conicity directed outwards, while the wall 13 on the body 11 has a cylindrical outer surface provided with a thread 18 which engages in an adjustable manner with a thread 16 and which ends internally

Le corps 11 comprend également un appendice tubulaire 22 s'étendant à partir de la bride 20, coaxiale au trou 11 The body 11 also includes a tubular appendage 22 extending from the flange 20, coaxial with the hole 11

Lorsqu'ils sont reliés ensemble, les corps 10 et 11 définissent une chambre intérieure 24 communiquant, d'un côté, extérieurement par un trou 14 et de l'autre côté avec le tuyau 9 par le trou 15 et dont le volume peut être modifié en vissant le corps 10 plus ou moins When they are connected together, the bodies 10 and 11 define an interior chamber 24 communicating, on one side, externally through a hole 14 and on the other side with the pipe 9 through the hole 15 and the volume of which can be modified by screwing the body 10 more or less

La chambre 24 loge un corps tubulaire 25 en élastomère élastiquement déformable, dont une paroi cylindrique 26 présente deux surfaces d'extrémités extérieures Chamber 24 houses a tubular body 25 made of elastically deformable elastomer, a cylindrical wall 26 of which has two outer end surfaces

Le raccord 1 est relié à des porte-tuyau 5 et 6 de façon extrêmement rapide en dévissant les corps 10 des corps 11 The connector 1 is connected to pipe holders 5 and 6 extremely quickly by unscrewing the bodies 10 from the bodies 11

Ayant inséré ledit appendice 7, chaque corps 10 est vissé graduellement sur le corps respectif 11 de manière à réduire le volume de la chambre respective 24 et à comprimer axialement le corps respectif 25. Etant donné que toute déformation extérieure radiale du corps 25, résultant de ladite compression axiale, est empêchée par le fait que la paroi 26 vient en contact avec la paroi 12, le corps 25 est déformé vers l'intérieur, ce qui a pour Having inserted said appendix 7, each body 10 is gradually screwed onto the respective body 11 so as to reduce the volume of the respective chamber 24 and to compress the respective body 25 axially. Since any radial external deformation of the body 25, resulting from said axial compression, is prevented by the fact that the wall 26 comes into contact with the wall 12, the body 25 is deformed inward, which has for
