Abstract
Description
La présente invention a pour objet une buse d'injection d'eau et/ou d'air pour une baignoire d'une installation de balnéothérapie, comprenant un corps creux présentant un orifice d'entrée destiné à être raccordé à une conduite d'amenée d'eau et/ou d'air sous pression à l'extérieur d'une paroi de la baignoire et un orifice de sortie débouchant par un trou fileté sur une de ses faces, un bouchon fileté destiné à être vissé dans le trou fileté de l'orifice de sortie du corps creux et présentant au moins un canal traversant destiné à déboucher à l'intérieur de la baignoire, et des moyens pour la fixation du corps creux à la paroi de la baignoire et pour l'étanchéité de cette fixation.The present invention relates to a water and / or air injection nozzle for a bathtub of a balneotherapy installation, comprising a hollow body having an inlet orifice intended to be connected to a supply pipe. water and / or air under pressure outside a wall of the bathtub and an outlet opening opening through a threaded hole on one of its faces, a threaded plug intended to be screwed into the threaded hole of the outlet of the hollow body and having at least one through channel intended to open into the interior of the bathtub, and means for fixing the hollow body to the wall of the bathtub and for sealing this fixing.
On connaît déjà une buse de ce genre qui comporte un corps creux constituant un écrou borgne dont le trou fileté de l'orifice de sortie débouche sur une face destinée à être mise en appui contre une paroi de la baignoire, à l'extérieur et en regard d'un trou de celle-ci, et un bouchon constituant une vis à tête d'appui dont la tige filetée est destinée à être enfilée dans le trou en question, depuis l'intérieur de la baignoire, et vissée dans le trou fileté du corps creux, la tête de cette vis étant destinée à venir en appui sur ladite paroi lors du vissage de ce bouchon dans le corps creux.A nozzle of this type is already known which comprises a hollow body constituting a blind nut, the threaded hole of the outlet orifice of which opens onto a face intended to be pressed against a wall of the bathtub, outside and in look of a hole thereof, and a plug constituting a support head screw whose threaded rod is intended to be threaded into the hole in question, from inside the bathtub, and screwed into the threaded hole of the hollow body, the head of this screw being intended to come to bear on said wall when the plug is screwed into the hollow body.
De la sorte, le corps creux de cette buse est fixé à la paroi de la baignoire par prise et serrage de cette paroi entre la tête de la vis formant le bouchon et l'écrou formant le corps creux.In this way, the hollow body of this nozzle is fixed to the wall of the bath by taking and tightening this wall between the head of the screw forming the plug and the nut forming the hollow body.
L'étanchéité de cette fixation est assurée par le moyen de deux joints annulaires dont le premier est disposé entre le corps creux de la buse et la face extérieure de la paroi de la baignoire pour éviter tout risque de fuite d'eau et/ou d'air sous pression entre ces deux éléments, et dont le second est disposé entre la tête du bouchon de la buse et la face intérieure de la paroi de la baignoire.The tightness of this attachment is ensured by means of two annular seals, the first of which is disposed between the hollow body of the nozzle and the outer face of the wall of the bathtub to avoid any risk of leakage of water and / or pressurized air between these two elements, the second of which is disposed between the head of the nozzle cap and the inner face of the wall of the bathtub.
Pour permettre le serrage ferme de la paroi de la baignoire entre la vis et l'écrou constitués ainsi respectivement par le bouchon et le corps creux de la buse, la face extérieure du bouchon atteignable par l'intérieur de la baignoire présente en son centre une prise constituée par un trou hexagonal pour l'engagement d'une clé à tige hexagonale. Un serrage ferme est en effet ici indispensable pour assurer l'étanchéité par un écrasement suffisant des deux joints annulaires de part et d'autre de la paroi de la baignoire.To allow firm clamping of the wall of the bathtub between the screw and the nut thus constituted respectively by the plug and the hollow body of the nozzle, the external face of the plug reachable by the interior of the bathtub has in its center a socket consisting of a hexagonal hole for engaging a hexagonal shank. Firm tightening is indeed essential here to ensure sealing by sufficient crushing of the two annular seals on either side of the wall of the bathtub.
Le bouchon de la buse ainsi constituée comporte un ou plusieurs canaux traversants constitués par des trous cylindriques axiaux débouchant dans un chambrage intérieur communicant avec l'orifice de sortie du corps creux, le nombre, la distribution et le diamètre de ces trous étant établis en fonction des différents effets thérapeutiques recherchés.The stopper of the nozzle thus formed comprises one or more through channels constituted by axial cylindrical holes opening into an internal recess communicating with the outlet orifice of the hollow body, the number, the distribution and the diameter of these holes being established as a function of the various therapeutic effects sought.
Cette buse connue est ppropriée pour une baignoire destinée à un effet thérapeutique bien défini ne nécessitant pas de démontages fréquents, ce qui est le cas pour des installations d'instituts de balnéothérapie comprenant plusieurs baignoires adaptées chacune à un effet thérapeutique particulier différent des autres. En effet, à chaque démontage le corps de la buse n'est plus retenu contre la paroi de la baignoire après dévissage du bouchon et tombe, et ceci risque de provoquer la nécessité du démontage concomitant de l'installation principale de la baignoire, ce qui est le cas notamment lors du démontage des buses du fond de celle-ci. A chaque remontage, il y a risque de création de problèmes d'étanchéité, par détérioration de joints.This known nozzle is suitable for a bathtub intended for a well-defined therapeutic effect which does not require frequent dismantling, which is the case for installations of balneotherapy institutes comprising several baths each adapted to a particular therapeutic effect different from the others. In fact, on each dismantling, the body of the nozzle is no longer retained against the wall of the bathtub after unscrewing the plug and falling, and this risks causing the need for concomitant disassembly of the main installation of the bathtub, which is the case in particular during the disassembly of the nozzles from the bottom thereof. With each reassembly, there is a risk of creating sealing problems, by deterioration of seals.
En outre, lors des contrôles périodiques d'entretien, le nettoyage des canaux des bouchons, qui est pratiqué de préférence in-situ pour éviter le démontage des buses, n'est pas une opération aisée.In addition, during periodic maintenance checks, cleaning the plug channels, which is preferably carried out in situ to avoid dismantling the nozzles, is not an easy operation.
Or il se trouve que devant l'engouement toujours plus grand du public pour les traitements par balnéothérapie, la demande va de plus en plus vers l'installation privée à une seule baignoire, du type familial, et ceci implique des changements fréquents de modéles de bouchon de buse, adaptés chaque fois à un effet thérapeutique différent ou progressif pour une même personne, ou aux différents membres d'une même famille d'utilisateurs.Now it turns out that in front of the ever-growing public enthusiasm for balneotherapy treatments, the demand goes more and more towards the private installation with a single bathtub, of the family type, and this implies frequent changes of models of nozzle cap, adapted each time to a different or progressive therapeutic effect for the same person, or to different members of the same user family.
Les inconvénients précités inhérents au démontage des buses, déjà lourds mais tout de même supportables pour des instituts équipés de plusieurs baignoires adaptées à des effets thérapeutiques différents, constituent par contre un handicap pour répondre au mieux à cette demande d'installations privées à une seule baignoire.The aforementioned drawbacks inherent in the dismantling of the nozzles, already heavy but still bearable for institutes equipped with several baths adapted to different therapeutic effects, on the other hand constitute a handicap to best meet this demand for private installations with a single bathtub .
C'est à ces inconvénients inhérents au démontage des buses que l'invention a pour but de porter remède.It is to these drawbacks inherent in the disassembly of the nozzles that the invention aims to remedy.
A cet effet, la buse selon l'invention, du type décrit en début d'exposé, est caractérisée en ce que le corps creux constitue une vis à tête d'appui dont la tige est destinée à passer au travers d'un trou de la paroi de la baignoire et dont la tête est destinée à être mise en appui contre cette paroi à l'intérieur de la baignoire, le trou fileté de son orifice de sortie débouchant sur la face extérieure de cette tête, en ce que ce corps creux est fixé à la paroi de la baignoire, aprés enfilage de sa tige dans le trou de cette paroi, par le moyen d'un écrou vissé sur ladite tige, et en ce que l'étanchéité de cette fixation est obtenue par le moyen d'un seul joint annulaire disposé entre la tête du corps creux et la paroi de la baignoire, à l'in térieur de celle-ci, et en ce que le bouchon est vissé dans la tête d'appui de la vis constituant le corps creux.To this end, the nozzle according to the invention, of the type described at the beginning of the description, is characterized in that the hollow body constitutes a support head screw whose rod is intended to pass through a the wall of the bathtub and the head of which is intended to be pressed against this wall inside the bathtub, the threaded hole of its outlet orifice opening onto the external face of this head, in that this hollow body is fixed to the wall of the bathtub, after threading its rod into the hole in this wall, by means of a nut screwed onto said rod, and in that the tightness of this fixing is obtained by means of a single annular seal placed between the head of the hollow body and the wall of the bath, inside térieur thereof, and in that the plug is screwed into the bearing head of the screw constituting the hollow body.
De la sorte, les moyens de fixation du corps creux de la buse à la paroi de la baignoire et l'étanchéité de cette fixation sont totalement indépendants du bouchon qui peut être ainsi dévissé et remplacé par un autre depuis l'intérieur de la baignoire, aussi souvent que nécessaire, et sans devoir intervenir sur la fixation du corps creux.In this way, the means for fixing the hollow body of the nozzle to the wall of the bath and the tightness of this fixing are completely independent of the plug which can thus be unscrewed and replaced by another from inside the bath, as often as necessary, and without having to intervene on the fixing of the hollow body.
Tout joint d'étanchéité entre le bouchon et le corps creux de la buse devient inutile, ce qui supprime les risques de détérioration d'un joint à ce niveau à chaque remontage; les vissages et dévissages fréquents d'un bouchon nécessités par les changements de modèles peuvent ainsi s'opérer par simple pression et pivotement du pouce de la main sur sa face apparente, ce qui supprime la nécessité d'une prise particulière telle qu'un sixpans creux pour l'usage d'une clé.Any seal between the plug and the hollow body of the nozzle becomes unnecessary, which eliminates the risk of deterioration of a seal at this level on each reassembly; frequent screwing and unscrewing of a plug required by model changes can thus be carried out by simple pressure and pivoting of the thumb of the hand on its visible face, which eliminates the need for a particular grip such as a sixpan hollow for the use of a key.
Le nettoyage des canaux des bouchons des buses d'une baignoire ainsi réalisées n'a plus besoin d'être effectué in situ de manière malaisée puisque le démontage et l'enlèvement desdits bouchons ne pose plus de problèmes.The cleaning of the channels of the plugs of the nozzles of a bath thus produced no longer needs to be carried out in situ uneasily since the disassembly and removal of said plugs no longer poses problems.
Le dessin annexé représente une buse selon l'état de la technique analysé précédemment ainsi qu'à titre d'exemple une forme d'exécution de l'objet de l'invention faisant ressortir encore d'autres avantages permis par sa conception de base.

La figure 1 montre clairement le corps creux 1 en forme d'écrou de la buse connue déjà mentionnée avec son orifice d'entrée 2 destiné à être raccordé de manière habituelle à un conduite d'amenée d'eau et/ou d'air sous pression, non représentée, et son orifice de sortie fileté 3 débouchant sur une face 4 destinée à être mise en appui sur la face extérieure d'une paroi 5 d'une baignoire, en regard d'un trou 6 de celle-ci.FIG. 1 clearly shows the hollow body 1 in the form of a nut of the known nozzle already mentioned with its
Le bouchon fileté 7 de cette buse connue constitue une vis à tête d'appui 8 dont la tige filetée 9 est destinée à être enfilée dans le trou 6 de la paroi 5, depuis l'intérieur de la baignoire, et vissée dans le trou fileté 3 du corps creux 1, cependant que la tête 8 est destinée à prendre appui contre cette paroi 5 lors du vissage de ce bouchon 7 dans le corps creux 1.The threaded plug 7 of this known nozzle constitutes a support head screw 8, the threaded rod 9 of which is intended to be threaded into the hole 6 of the
L'étanchéité de la fixation obtenue par serrage de la paroi 5 entre la tête 8 du bouchon 7 et la face 4 du corps creux 1 est assurée par deux joints annulaires 10 et 11. Le premier joint annulaire 10, de forte section rectangulaire, est disposé entre le corps creux 1 et la paroi 5 pour éviter tout risque de fuite d'eau et/ou d'air sous pression entre ces deux éléments. Le second joint annulaire 11, du type "o-ring", est disposé entre la tête 8 du bouchon 7 et la face intérieure de la paroi 5 de la baignoire.The tightness of the fixing obtained by tightening the
La figure 2 fait ressortir le trou hexagonal 12 de la face extérieure du bouchon 7 destiné à permettre un serrage ferme à l'aide d'une clé à tige hexagonale cependant que le corps creux 1 visible figure 1 comporte sur sa périphérie un trou cylindrique 13 destiné à permettre sa retenue par une clé à griffe.Figure 2 highlights the
Les canaux d'injection d'eau et/ou d'air sous pression du bouchon 1 sont ici constitués par des trous cylindriques 14 débouchant dans un chambrage 15, le nombre et le diamètre de ces trous pouvant évidemment varier selon l'effet thérapeutique recherché.The water and / or pressurized air injection channels of the plug 1 are here constituted by
Les problèmes déjà signalés créés par le démontage et l'enlèvement du bouchon 7 de cette buse connue sont rendus bien compréhensibles par la figure 1 qui montre qu'après dévissage de ce bouchon 7, rien ne peut empêcher le corps creux 1 de tomber.The already reported problems created by dismantling and removing the plug 7 from this known nozzle are made very understandable by FIG. 1 which shows that after unscrewing this plug 7, nothing can prevent the hollow body 1 from falling.
La forme d'exécution de la buse selon l'invention représentée figure 3 remédie de manière simple à cet inconvénient et porte en soi encore d'autres avantages.The embodiment of the nozzle according to the invention shown in FIG. 3 overcomes this drawback in a simple manner and in itself brings still other advantages.
Le corps creux 16 de cette buse constitue une vis à tête d'appui 17 dont la tige 20, 21 est destinée à être passée au travers d'un trou 18 d'une paroi 19 d'une baignoire et dont la tête 17 est destinée à être mise en appui contre cette paroi 19 à l'intérieur de la baignoire.The
La tige 20, 21 du corps creux 16 est composée d'une partie supérieure filetée 20 située sous sa tête 17 et d'une partie terminale 21 présentant sur sa paroi latérale un orifice d'entrée 22 destiné à être raccordé de manière habituelle à une conduite, non représentée, d'amenée d'eau et/ou d'air sous pression.The
Le corps creux 16 comporte un orifice de sortie constitué par un trou axial fileté 23 débouchant sur la face extérieure 24 de sa tête 17 et communicant avec l'orifice d'entrée 22 par l'intérmédiaire d'un chambrage 25 et d'un conduit 26.The
Le corps creux 16 ainsi constitué est destiné à être fixé à la paroi 19 de la baignoire, après enfilage de sa tige 20, 21 dans le trou 18 de cette paroi, par le moyen d'un écrou 27 vissé sur la partie filetée 20 de cette tige.The
L'étanchéité de cette fixation est obtenue par le moyen d'un seul joint annulaire 28, du type "o-ring", disposé entre la tête 17 du corps creux 16 et la paroi 19 de la baignoire, à l'intérieur de celle-ci. Un autre joint entre l'écrou 27 et la face extérieure de la paroi 19 est en effet inutile ici du fait qu'aucune fuite d'air et/ou d'eau sous pression n'est possible à ce niveau, contrairement à la buse connue décrite précédemment.The tightness of this attachment is obtained by means of a single
Le bouchon fileté 29 de la buse selon l'invention, qui est destiné à être vissé dans l'orifice de sortie filetée 23 du corps creux, se compose d'une partie filetée proprement dite 30 prolongée sur sa face inférieure par un bossage cylindrique coaxial 31, de plus faible diamètre. Ce bossage 31 est destiné, en fin de course de vissage du bouchon fileté 29 dans l'orifice 23 du corps creux 16, à prendre appui contre le fond 32 du chambrage 25 de ce dernier, cependant que la face supérieure 33 de ce bouchon vient araser la face supérieure 24 dudit corps creux.The threaded
Grâce à cette conception, les canaux traversants d'injection d'eau et/ou d'air sous pression du bouchon fileté 29 peuvent être très simplement constitués, comme il ressort bien de la figure 4, par des saignées 34 pratiquées dans le filetage de sa partie filetée 30, la profondeur de ces saignées 34 étant supérieure à la hauteur dudit filetage et leur nombre et leur section pouvant évidemment varier selon l'effet thérapeutique recherché.Thanks to this design, the through channels for injecting water and / or air under pressure of the threaded
Par comparaison des figures 1 et 3, on comprend aisément les avantages déjà énoncés de la buse selon l'invention relatifs à la facilité et à l'absence de risques présentés par les dévissages et revissages fréquents d'un bouchon fileté 29 pratiqués aussi bien pour des raisons de nettoyage que de changement de modèle.By comparison of FIGS. 1 and 3, it is easy to understand the advantages already stated of the nozzle according to the invention relating to the ease and the absence of risks presented by the frequent unscrewing and re-screwing of a plug. threaded 29 practiced for both cleaning and model change reasons.
Bien entendu, la conception des canaux sous forme de saignées 34 du filetage du bouchon 29 n'est pas limitative et ces canaux peuvent être prévus sous forme de trous, comme les trous 14 de la buse connue. Dans ce cas, le bouchon fileté peut comporter une collerette d'appui débordante de sa face supérieure, à la place du bossage 31.Of course, the design of the channels in the form of
Cependant, la forme d'exécution donnée en exemple porte en soi des avantages supplémentaires, permis par sa conception de base.However, the exemplary embodiment carries in itself additional advantages, enabled by its basic design.
En effet, par rapport aux canaux en forme de trous tels que les trous 14 du bouchon de la buse connue représentée figures 1 et 2, trous qui ne peuvent pas être conçus autrement pour ce type de buse, les canaux en forme de saignées 34 du bouchon 29 de la buse selon l'invention, outre leur simplicité d'exécution, présentent l'avantage d'accroître la facilité de leur nettoyage, une fois le bouchon enlevé. En outre, en service, ces canaux 34 provoquent une fine émulsion air-eau par l'effet du passage du fluide sous pression sur le filetage 23 sur toute leur longueur, et cette émulsion de type fin casse le bruit inhérent à ce genre de système d'injection par buse.Indeed, compared to the channels in the form of holes such as the
Enfin, il va de soi que la buse selon l'invention est applicable non seulement aux parois de baignoire mais également à tout équivalent tel que par exemple un revêtement partiel ou total d'une baignoire ou d'une piscine.Finally, it goes without saying that the nozzle according to the invention is applicable not only to the walls of a bathtub but also to any equivalent such as for example a partial or total coating of a bathtub or a swimming pool.
