Abstract
Description
La présente invention a trait aux appareils sanitaires du genre des douches et douchettes et elle vise plus particulièrement les canalisations flexibles destinées à l'alimentation en eau desdits appareils. The present invention relates to sanitary devices such as showers and showers and it relates more particularly to flexible pipes intended for the supply of water to said devices.
On sait que ces canalisations flexibles sont constituées par un tube en caoutchouc ou en une matière synthétique souple qui est engagé à l'intérieur d'une gaine de protection réalisée par enroulement en spirale d'un feuillard dont les bords sont assemblés par agrafage. Une telle canalisation se révèle assez délicate car il arrive de manière relativement fréquente que sous l'effet d'une traction trop importante exercée sur elle au cours de l'utilisation normale de la douche, la canalisation se plie de façon trop prononcée au niveau de son extrémité qui est fixée à la robinetterie, en provoquant le dégrafage de la gaine. It is known that these flexible pipes consist of a rubber tube or a flexible synthetic material which is engaged inside a protective sheath produced by spiral winding of a strip whose edges are assembled by stapling. Such a pipe proves to be quite delicate because it happens relatively frequently that under the effect of too much traction exerted on it during normal use of the shower, the pipe bends too much at the level of its end which is fixed to the taps, causing the unclogging of the sheath.
C'est à cet inconvénient qu'entend remédier la présente invention, laquelle consiste à faire comporter à celle au moins des extrémités de la canalisation flexible qui est fixée à la robinetterie, un manchon intérieur en une matière synthétique semi-rigide qui est propre à se déformer élastiquement en encaissant ainsi les efforts de traction exercés sur la canalisation au niveau de son raccordement. It is to this drawback that the present invention intends to remedy, which consists in having at least that of the ends of the flexible pipe which is fixed to the fittings, an inner sleeve made of a semi-rigid synthetic material which is suitable for deform elastically, thereby absorbing the tensile forces exerted on the pipe at its connection.
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 axiale schématique de l'une des extrémités d'une canalisation flexible d'alimentation établie conformément à la présente invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a schematic axial section of one of the ends of a flexible supply pipe established in accordance with the present invention.
Fig. 2 illustre une variante. Fig. 2 illustrates a variant.
A la façon usuelle, la canalisation représentée en fig. 1 comprend un tube intérieur 1 en une matière souple qu'on peut supposer être constituée par un caoutchouc naturel ou synthétique, lequel tube est recouvert par une gaine métallique de protection 2 du type agrafé. Ces deux éléments 1 et 2 sont assemblés au niveau d'une virole 3 en métal, sur laquelle coulisse une bague 4 pour la fixation, par vissage, de l'extrémité considérée de la canalisation flexible sur la tubulure filetée Sa d'un appareil de robinetterie tel que 5. In the usual way, the pipe shown in fig. 1 comprises an inner tube 1 made of a flexible material which can be assumed to be constituted by a natural or synthetic rubber, which tube is covered by a metal protective sheath 2 of the stapled type. These two elements 1 and 2 are assembled at the level of a metal ferrule 3, on which slides a ring 4 for fixing, by screwing, the end considered of the flexible pipe to the threaded pipe Sa of an apparatus for fittings such as 5.
Conformément à l'invention, on a armé l'extrémité de la canalisation flexible à l'aide d'un manchon intérieur 6, réalisé en une matière synthétique semi-rigide, susceptible de se déformer élastiquement. Ce manchon 6 est introduit entre la gaine métallique 2 et le tube 1, sa fixation en place étant opérée de toute manière appropriée ; dans l'exemple de réalisation envisagé, on a supposé que la base du manchon 6 est pourvue d'un rebord annulaire qui est pincé entre le bord d'extrémité de la virole 3 et la bride terminale 7a d'une douille de retenue 7 engagée à force dans l'ouverture de tube 1, laquelle bride 7a forme appui pour le joint plat usuel 8 destiné à assurer l'étanchéité du raccordement réalisé par la bague 4. In accordance with the invention, the end of the flexible pipe was reinforced with the aid of an inner sleeve 6, made of a semi-rigid synthetic material, capable of deforming elastically. This sleeve 6 is introduced between the metal sheath 2 and the tube 1, its fixing in place being effected in any suitable manner; in the exemplary embodiment envisaged, it has been assumed that the base of the sleeve 6 is provided with an annular flange which is pinched between the end edge of the ferrule 3 and the end flange 7a of a retaining sleeve 7 engaged by force in the tube opening 1, which flange 7a forms a support for the usual flat seal 8 intended to seal the connection produced by the ring 4.
On conçoit que par suite de sa déformabilité élastique, ce manchon 6 joue le rle d'amortisseur lorsque la canalisation flexible est soumise à des efforts de traction trop importants, ladite canalisation se courbant en pareil cas suivant le profil indiqué en A. L'arc de courbure est suffisamment important pour éviter tout risque d'endommagement de la canalisation par dégrafage des spires de la gaine 2, à l'inversa de ce qui se passe en l'absence du manchon 6 (profil cassé montré en B). It is understood that due to its elastic deformability, this sleeve 6 plays the role of shock absorber when the flexible pipe is subjected to excessive tensile forces, said pipe bending in such a case according to the profile indicated in A. The arc of curvature is large enough to avoid any risk of damage to the pipe by unclipping the turns of the sheath 2, conversely to what happens in the absence of the sleeve 6 (broken profile shown in B).
Il va de soi que les deux extrémités de la canalisation flexible sont susceptibles d'être équipées l'une et l'autre d'un manchon amortisseur 6, bien que normalement l'extrémité fixée à la douchette comporte moins de risque de rupture. On comprend en outre qu'on peut imaginer d'autres systèmes pour le maintien en place d'un tel manchon à l'intérieur de l'extrémité de la canalisation. La longueur de chaque manchon 6 peut varier dans une large mesure. It goes without saying that the two ends of the flexible pipe are capable of being fitted both with a shock-absorbing sleeve 6, although normally the end fixed to the hand shower has less risk of breakage. It is further understood that one can imagine other systems for holding in place such a sleeve inside the end of the pipe. The length of each sleeve 6 can vary to a large extent.
Dans la variante de mise en oeuvre illustrée en fig. 2, l'extrémité considérée du tube 1 est engagée sur un embout 6a à plus petit diamètre prévu à l'extrémité libre du manchon 6, la retenue étant assurée à l'aida d'une douille sertie 9. Le fonctionnement reste identique et l'on conçoit qu'on pourrait imaginer d'autres formes de réalisation. In the variant of implementation illustrated in FIG. 2, the end considered of the tube 1 is engaged on a nozzle 6a with a smaller diameter provided at the free end of the sleeve 6, the retention being ensured by means of a crimped socket 9. The operation remains identical and the 'we understand that we could imagine other embodiments.
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'a titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait par en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which we would not depart by replacing the execution details described by all other equivalents.
