Description

  

  Raccord permettant de relier un tuyau à un organe tubulaire lisse.    <B>Il</B> existe actuellement sur le marché une  foule d'appareils hydrauliques pour usages  ménagers, artisanaux ou professionnels. Toute  fois, la. diffusion de ces appareils est rendue  difficile par la grande variété des robinets  installés. En effet, du fait de cette grande  variété des robinets, le raccordement de ces  appareils est difficile à réaliser, spécialement  dans le cas de robinets à bec lisse. Ces becs  sont de diamètre très variable, de sorte qu'un  manchon de caoutchouc, même bridé est, ainsi  que la pratique l'a prouvé, absolument insuf  fisant lorsque la pression dépasse une ou deux  atmosphères.  



  La présente invention a pour objet un     rac-          eord    permettant de relier un tuyau à un or  gane tubulaire lisse qui est caractérisé par un  corps présentant un     perçage    axial débouchant  dans un     chambrage    pourvu d'un organe  d'étanchéité et destiné à recevoir l'extrémité       duidit    organe tubulaire lisse et portant, d'une       part,    l'une des parties d'un accouplement per  mettant de relier ledit corps à un tuyau et,  d'autre part, des organes de fixation permet  tant de fixer ledit corps sur l'extrémité de  L'organe tubulaire.  



  Selon le dessin annexé, donné à titre  d'exemple, le raccord comporte un corps de  révolution 1 présentant un perçage axial 2 dé  bouchant dans un     chambrage    3. Ce corps 1  présente à l'une de ses extrémités un filetage  4 normalisé, par exemple 3/8 gaz, constituant  l'une des parties d'un accouplement permet-    tant de fixer sur le corps 1 un tuyau ou une  conduite.  



  Le fond du     chambrage    3 présente une  gorge 5 dans laquelle est placé un anneau  d'étanchéité 6 en matière souple et élastique,  telle que du caoutchouc par exemple.  



  Enfin, le corps 1 est muni de trois vis 7  traversant     radialement    la paroi du     chambrage     3 et pourvues     d'une        pointe.    Ces vis permet  tent de fixer le corps 1 sur l'extrémité d'un  organe tubulaire 8 constitué, par exemple,  par l'extrémité d'un robinet à bec lisse.  



  Pour fixer le corps 1 sur l'organe 8, il  suffit d'engager le corps sur cet organe et  d'exercer une poussée dans le sens de la flèche  a pendant le serrage des vis de fixation 7,  afin que l'extrémité 9 de cet organe 8 appli  que l'anneau 6 dans la gorge 5 et s'imprime  dans cet anneau.  



  En examinant le dessin annexé, on voit  que la différence existant entre la pression  régnant dans l'espace dans lequel circule le  fluide et la pression atmosphérique régnant  dans l'espace annulaire formé par la paroi ex  terne de l'organe 8 et la paroi interne du       chambrage    3, tend à repousser l'anneau 6 dans  cet espace annulaire et donc à assurer     l'étan-,          chéité    du joint par     autoserrage.     



  Les limites inférieures et supérieures des  diamètres extérieurs d'organes tubulaires lis  ses 8 qu'un même raccord peut recevoir en  assurant l'étanchéité, sont comprises entre le     i         diamètre du     chambrage    3 et le diamètre inté  rieur de l'anneau 6. Par le choix judicieux de  ces deux diamètres, le constructeur a la. possi  bilité de réaliser un raccord pouvant être fixé  sur toits les robinets à bec lisse pouvant se  présenter lors de l'emploi d'un appareil donné,  par exemple sur     toits    les robinets de cuisine.  



  Une forme d'exécution du raccord selon  l'invention a été décrite ici en référence au  dessin annexé, mais il va sans dire que les di  vers éléments et organes décrits peuvent sans  autre être remplacés par des éléments équi  valents.     Ainsi,    par exemple, le filetage 4 pour  rait être remplacé par l'une des parties d'un  autre type d'accouplement, tel qu'un accou  plement à baïonnette par exemple. De même,  le nombre des vis 7 pourrait être plus grand  que trois.



  Fitting for connecting a pipe to a smooth tubular member. <B> There </B> currently exist on the market a host of hydraulic devices for household, craft or professional use. However, the. Distribution of these devices is made difficult by the wide variety of faucets installed. Indeed, due to this great variety of taps, the connection of these devices is difficult to achieve, especially in the case of taps with smooth spouts. These nozzles are of very variable diameter, so that a rubber sleeve, even flanged, is, as practice has proved, absolutely insufficient when the pressure exceeds one or two atmospheres.



  The present invention relates to a connector making it possible to connect a pipe to a smooth tubular organ which is characterized by a body having an axial bore opening into a recess provided with a sealing member and intended to receive the end. duidit smooth tubular member and carrying, on the one hand, one of the parts of a coupling making it possible to connect said body to a pipe and, on the other hand, fastening members make it possible to fix said body on the end of the tubular organ.



  According to the appended drawing, given by way of example, the connector comprises a body of revolution 1 having an axial bore 2 which plugs into a recess 3. This body 1 has at one of its ends a standardized thread 4, for example 3/8 gas, constituting one of the parts of a coupling for fixing to the body 1 a pipe or a pipe.



  The bottom of the recess 3 has a groove 5 in which is placed a sealing ring 6 made of flexible and elastic material, such as rubber for example.



  Finally, the body 1 is provided with three screws 7 passing radially through the wall of the recess 3 and provided with a point. These screws make it possible to fix the body 1 on the end of a tubular member 8 constituted, for example, by the end of a tap with a smooth spout.



  To fix the body 1 on the member 8, it suffices to engage the body on this member and to exert a thrust in the direction of the arrow a during the tightening of the fixing screws 7, so that the end 9 of this organ 8 appli that the ring 6 in the groove 5 and is imprinted in this ring.



  By examining the attached drawing, it can be seen that the difference between the pressure prevailing in the space in which the fluid circulates and the atmospheric pressure prevailing in the annular space formed by the outer wall of the member 8 and the internal wall of the recess 3 tends to push the ring 6 back into this annular space and therefore to ensure the sealing of the seal by self-tightening.



  The lower and upper limits of the external diameters of tubular members lis its 8 that the same connector can receive while ensuring the tightness, are between the i diameter of the recess 3 and the internal diameter of the ring 6. By the judicious choice of these two diameters, the manufacturer has the. possibility of making a connection which can be fixed on roofs the taps with smooth spout which may be present when using a given device, for example on roofs the kitchen taps.



  An embodiment of the connector according to the invention has been described here with reference to the appended drawing, but it goes without saying that the various elements and members described can without further be replaced by equivalent elements. Thus, for example, the thread 4 could be replaced by one of the parts of another type of coupling, such as a bayonet coupling for example. Likewise, the number of screws 7 could be greater than three.
