Description

La présente invention concerne un dispositif à pomme d'arrosoir destiné à équiper les douches ou les douchettes.The present invention relates to a sprinkler head device intended to equip showers or hand showers.

Il existe un certain nombre de dispositifs à pomme d'arrosoir visant, par exemple, à diminuer la consommation d'eau grâce à l'adjonction de dispositifs, tels des ajutages, limitant le débit d'eau, ou visant encore à obtenir un jet de puissance et de largeur réglables. A cet égard, on connaît notamment le brevet français FR-A-824 149 au nom de la Société JACOB DELAFON qui concerne un dispositif servant à la dispersion et à la pulvérisation d'eau, utilisable notamment dans les appareils à douche ou les jets d'arrosage ; ce dispositif de pulvérisation comporte un noyau intérieur hélicoïdal imprimant au jet liquide un mouvement de rotation, ce noyau hélicoïdal étant disposé dans un manchon concentrique, mobile de préférence axialement, ce qui permet de modifier l'espace libre entre ledit noyau hélicoïdal et ledit manchon mobile et, par suite, de régler la finesse de pulvérisation. Des dispositifs équivalents sont également proposés dans les brevets américains US-A-3 104 829 ou US-A-3 146 674, ces dispositifs comprenant encore un dispositif susceptible d'imprimer un mouvement tourbillonnaire au jet liquide, de manière à obtenir un brassage d'eau et d'air propre à maintenir en sortie du dispositif une pluie d'arrosage comparable à celle obtenue conventionnellement, pour une consommation d'eau nettement réduite.There are a number of sprinkler heads designed, for example, to reduce water consumption through the addition of devices, such as nozzles, limiting the flow of water, or also aimed at obtaining a jet. adjustable power and width. In this regard, the French patent FR-A-824,149 is known in the name of the JACOB DELAFON Company, which relates to a device used for the dispersion and spraying of water, usable in particular in shower appliances or water jets. 'watering; this spraying device comprises a helical inner core imparting a rotary movement to the liquid jet, this helical core being disposed in a concentric sleeve, preferably axially movable, which makes it possible to modify the free space between said helical core and said movable sleeve and, consequently, to regulate the fineness of spraying. Equivalent devices are also proposed in American patents US-A-3,104,829 or US-A-3,146,674, these devices also comprising a device capable of imparting a vortex movement with a liquid jet, so as to obtain a mixing of water and clean air to maintain at the outlet of the device a rain shower comparable to that obtained conventionally, for a significantly reduced water consumption.

Dans tous ces dispositifs connus, il n'est cependant pas possible de régler séparément l'intensité et la finesse de la pulvérisation du jet liquide. Par exemple, dans le brevet JACOB DELAFON, le noyau hélicoïdal proposé comme moyen déflecteur, imprimant au jet liquide un mouvement de rotation, coulisse coaxialement à l'intérieur d'un manchon d'alésage tronconique permettant d'obtenir simultanément, soit un tourbillon correspondant à un haut degré de dispersion et de pulvérisation d'un jet liquide intense, soit un ensemble de veines d'eau hélicoïdales entourées d'une nappe liquide conique, sans composante tangentielle, qui atténuent le mouvement tourbillonnaire et le degré de finesse de la pulvérisation. Il est donc impossible d'obtenir un jet large peu intense, ou tout simplement intense sans être large, et ceci pour une même consommation d'eau (il serait bien entendu possible d'augmenter l'intensité du jet en augmentant le débit). Un autre inconvénient des dispositifs connus consiste en ce que, lorsque le jet est dispersé au maximum, il est systématiquement appauvri en son centre, ce qui constitue pour nombre d'utilisateurs une gêne importante.In all these known devices, however, it is not possible to separately regulate the intensity and the fineness of the spraying of the liquid jet. For example, in the JACOB DELAFON patent, the helical core proposed as deflector means, imparting a rotary movement to the liquid jet, slides coaxially inside a frustoconical bore sleeve making it possible to simultaneously obtain either a corresponding vortex to a high degree of dispersion and spraying of a liquid jet intense, that is to say a set of helical veins of water surrounded by a conical liquid sheet, without tangential component, which attenuate the vortex movement and the degree of fineness of the spraying. It is therefore impossible to obtain a broad jet that is not very intense, or simply intense without being broad, and this for the same water consumption (it would of course be possible to increase the intensity of the jet by increasing the flow rate). Another disadvantage of the known devices consists in that, when the jet is dispersed as much as possible, it is systematically depleted in its center, which constitutes for a number of users a significant annoyance.

La présente invention vise à remédier à ces inconvénients en proposant un dispositif à pomme d'arrosoir destiné à équiper les douches ou les douchettes au niveau de la sortie d'une conduite d'eau, caractérisé en ce qu'il comporte au moins un moyen déflecteur constitué par une pluralité d'aubes périphériques d'un axe central, disposé coaxialement dans une première chambre intérieure, préférentiellement cylindrique, qui est ménagée dans une douille vissée à force à l'extrémité de ladite conduite d'eau, ladite première chambre étant prolongée vers le bas par une seconde chambre intérieure, cylindrique ou conique, débouchant sur un ajutage calibré en regard duquel on peut rapprocher ou éloigner une plaque de sortie percée formant la face avant d'un manchon concentrique monté coulissant autour de ladite douille.The present invention aims to remedy these drawbacks by proposing a device with a sprinkler head intended to equip showers or hand showers at the outlet of a water pipe, characterized in that it comprises at least one means deflector constituted by a plurality of peripheral blades of a central axis, arranged coaxially in a first interior chamber, preferably cylindrical, which is formed in a socket screwed by force to the end of said water pipe, said first chamber being extended downwards by a second inner chamber, cylindrical or conical, leading to a calibrated nozzle opposite which a pierced outlet plate can be brought closer or further apart forming the front face of a concentric sleeve mounted sliding around said bushing.

Selon la présente invention, la position de l'ajutage calibré est donc fixe et l'intensification du jet d'eau tourbillonnaire issu du moyen déflecteur supérieur qui en résulte n'est, de cette manière, en aucune façon dépendante de la position longitudinale du manchon concentrique, coulissant autour de la douille, et qui porte, à son extrémité, une plaque de sortie percée de trous dont le déplacement longitudinal permet de faire varier l'angle de diffusion du jet liquide. A cet égard, lorsque la plaque de sortie se trouve au plus près de l'ajutage calibré, le jet liquide est intense et présente une largeur maximale ; à l'inverse, lorsque la plaque de sortie du manchon est éloignée au maximum par rapport à l'ajutage calibré fixe, le jet liquide sortant de cet ajutage vient taper la paroi interne dudit manchon, cassant ainsi la violence du jet tout en réduisant sa largeur.According to the present invention, the position of the calibrated nozzle is therefore fixed and the intensification of the swirling water jet coming from the upper deflector means which results therefrom is, in this way, in no way dependent on the longitudinal position of the concentric sleeve, sliding around the sleeve, and which carries, at its end, an outlet plate pierced with holes whose longitudinal displacement makes it possible to vary the angle of diffusion of the liquid jet. In this regard, when the outlet plate is closest to the calibrated nozzle, the liquid jet is intense and present maximum width; conversely, when the outlet plate of the sleeve is as far as possible from the fixed calibrated nozzle, the liquid jet leaving this nozzle strikes the internal wall of said sleeve, thus breaking the violence of the jet while reducing its width.

En outre, selon une caractéristique complémentaire de la présente invention, la plaque de sortie percée formant la face avant du manchon comporte un trou central, préférentiellement oblong, entouré de trous périphériques plus petits, régulièrement répartis autour dudit trou central ; de cette manière, il existe une première position intermédiaire du manchon le long de la douille, pour laquelle le jet liquide diffusé en sortie de l'ajutage calibré fixe vient juste atteindre la limite entre le trou central et les trous périphériques de la plaque de sortie, cette première position intermédiaire déterminant la limite au-delà de laquelle le jet est intense. Puis, entre cette première position intermédiaire et la position d'élongation maximale du manchon le long de la douille, le jet liquide atteint les trous périphériques de la plaque de sortie, sans toutefois frapper la paroi interne du manchon, ledit jet étant alors diffusé plus finement tout en ayant perdu de sa puissance. Enfin, lorsque le manchon dépasse cette seconde position intermédiaire, la puissance du jet va en décroissant avec une largeur quasiment fixe.In addition, according to a complementary characteristic of the present invention, the drilled outlet plate forming the front face of the sleeve has a central hole, preferably oblong, surrounded by smaller peripheral holes, regularly distributed around said central hole; in this way, there is a first intermediate position of the sleeve along the sleeve, for which the liquid jet diffused at the outlet of the fixed calibrated nozzle just reaches the limit between the central hole and the peripheral holes of the outlet plate , this first intermediate position determining the limit beyond which the jet is intense. Then, between this first intermediate position and the position of maximum elongation of the sleeve along the sleeve, the liquid jet reaches the peripheral holes of the outlet plate, without however striking the internal wall of the sleeve, said jet then being diffused more finely while having lost its power. Finally, when the sleeve exceeds this second intermediate position, the power of the jet decreases with an almost fixed width.

Selon une autre caractéristique de la présente invention, il est prévu que le moyen déflecteur à aubes soit pourvu de moyens auxiliaires permettant de nourrir le jet liquide sortant de l'ajutage en son centre et, à cet égard, la présente invention propose deux variantes, à savoir :

  • chaque aube du moyen déflecteur présente une échancrure inférieure favorisant le regroupement de certains filets d'eau le long de son axe central, ledit axe central se termine par une pointe recomposant lesdits filets d'eau en un seul jet tourbillonnaire central de viscosité réduite.
  • l'axe central du moyen déflecteur à aubes est alésé longitudinalement pour former un tube laissant le passage à un flux d'eau central non tourbillonnaire permettant de nourrir directement le jet en son centre.
According to another characteristic of the present invention, provision is made for the blade deflector means to be provided with auxiliary means making it possible to feed the liquid jet leaving the nozzle at its center and, in this regard, the present invention proposes two variants, to know :
  • each blade of the deflector means has a lower notch favoring the grouping of certain streams of water along its central axis, said central axis ends with a point recomposing said streams of water in a single central vortex jet of reduced viscosity.
  • the central axis of the deflector means with blades is bored longitudinally to form a tube allowing passage to a non-vortex central water flow allowing direct feeding of the jet at its center.

Ces caractéristiques complémentaires du moyen déflecteur à aubes, équivalentes quant à leur résultat, ne nuisent aucunement à l'économie d'eau que procure le moyen déflecteur à aubes en amont de l'ajutage. En outre, la portion centrale du jet liquide ainsi traitée est suffisamment petite pour ne pas influer sur le comportement du liquide animé, en périphérie, d'un mouvement tourbillonnaire.These complementary characteristics of the deflector means with blades, equivalent as to their result, do not in any way harm the water saving which the deflector means with blades upstream of the nozzle provides. In addition, the central portion of the liquid jet thus treated is small enough not to influence the behavior of the animated liquid, at the periphery, of a vortex movement.

Selon encore une autre caractéristique de l'invention, la structure de la portion centrale du jet est préservée tout le long de son trajet dans le dispositif à pomme d'arrosoir puisque, ainsi qu'il est mentionné plus haut, la plaque de sortie est percée en son centre d'un trou oblong, dont le rôle principal est de laisser passer, sans perte de puissance ni déviation, ladite portion centrale du jet.According to yet another characteristic of the invention, the structure of the central portion of the jet is preserved all along its path in the sprinkler head device since, as mentioned above, the outlet plate is pierced in its center by an oblong hole, the main role of which is to let pass, without loss of power or deviation, said central portion of the jet.

D'autres caractéristiques et avantages de la présente invention ressortiront mieux de la description qui va suivre de deux formes de réalisation données à titre d'exemples non limitatifs d'un dispositif à pomme d'arrosoir conforme à la présente invention en référence aux dessins annexés sur lesquels :

  • la figure 1 présente deux demi-vues, l'une extérieure, l'autre en coupe transversale, d'un dispositif à pomme d'arrosoir conforme à une première forme de réalisation de l'invention,

Other characteristics and advantages of the present invention will emerge more clearly from the description which follows of two embodiments given by way of nonlimiting examples of a sprinkler head device according to the present invention with reference to the accompanying drawings. on which ones :
  • FIG. 1 shows two half-views, one exterior, the other in cross section, of a sprinkler head device according to a first embodiment of the invention,

  • FIG. 5 is a top view of the deflector means shown in FIG. 4.

On décrira tout d'abord les parties communes des deux formes d'exécution de l'invention telles que représentées sur les figures 1 et 3. Ainsi, le dispositif à pomme d'arrosoir selon l'invention, qui est monté à l'extrémité d'une conduite d'eau 1 de manière à constituer un dispositif de douche, comporte une douille 2, cylindrique et creuse, qui est pourvue, à sa partie supérieure, d'un filetage intérieur 2a, destiné à être vissé à force sur le filetage extérieur 1a de ladite conduite 1. Cette douille 2 sert de corps d'assemblage à un ensemble de moyens tels que :

  • un moyen d'arrêt des corps étrangers transportés par l'eau venant de la conduite 1, constitué par une crépine 3 dont les trous 3a ont un calibre déterminé par la dimension des grains de sable, des boues, des morceaux de calcaire ou de tartre, que l'on veut stopper. Cette crépine 3 est placée à l'extrémité basse du filetage intérieur 2a de la douille 2, en appui positif sur une rive annulaire 4 en déport intérieur vis à vis dudit filetage 2a ; la profondeur de cette rive annulaire 4 est inférieure à l'épaisseur de la crépine cylindrique 3, de sorte que cette dernière puisse servir de joint d'étanchéité entre la conduite d'eau 1 et la douille 2.
  • un moyen déflecteur 5, susceptible de créer des filets d'eau tourbillonnaires modifiant la viscosité apparente du fluide, et procurant une économie d'eau. Ce moyen déflecteur 5 est situé dans une première chambre intérieure 6 cylindrique, de diamètre égal au diamètre intérieur de la rive annulaire 4.
We will first describe the common parts of the two embodiments of the invention as shown in Figures 1 and 3. Thus, the sprinkler head device according to the invention, which is mounted at the end of a water pipe 1 so as to constitute a shower device, comprises a socket 2, cylindrical and hollow, which is provided, at its upper part, with an internal thread 2 a , intended to be screwed by force onto the external thread 1a of said pipe 1. the sleeve 2 serves as an assembly body with a set of means such as:
  • stop means foreign bodies transported by water from line 1, consisting of a strainer 3, the holes 3 a have a size determined by the size of grains of sand, sludge, pieces of limestone or tartar, which we want to stop. This strainer 3 is placed at the lower end of the internal thread 2 a of the sleeve 2, in positive support on an annular edge 4 in internal offset with respect to said thread 2 a ; the depth of this annular edge 4 is less than the thickness of the cylindrical strainer 3, so that the latter can serve as a seal between the water pipe 1 and the sleeve 2.
  • a deflector means 5, capable of creating swirling streams of water modifying the apparent viscosity of the fluid, and providing water savings. This deflector means 5 is located in a first cylindrical interior chamber 6, of diameter equal to the interior diameter of the annular edge 4.

Conformément aux figures 2, 4 et 5, le moyen déflecteur 5 est constitué par une pluralité d'aubes 7 périphériques d'un axe central 8, colinéaire avec l'axe de symétrie de la douille 2 cylindrique ; les aubes 7 sont inclinées verticalement d'un angle proche de 45°, et se succèdent régulièrement du haut vers le bas de l'axe central 8.According to Figures 2, 4 and 5, the deflector means 5 is constituted by a plurality vanes 7 peripheral to a central axis 8, collinear with the axis of symmetry of the cylindrical sleeve 2; the vanes 7 are inclined vertically by an angle close to 45 °, and follow one another regularly from the top to the bottom of the central axis 8.

Par ailleurs, chacune des aubes 7 présente une arête supérieure 7a, l'ensemble des arêtes 7a définissant un même plan vertical (passant, en outre, par l'axe central 8). De cette façon, le fluide ayant traversé la crépine cylindrique 3 glisse sur les aubes 7 qui impriment à ce fluide un mouvement tourbillonnaire, et le brassent avec l'air contenu dans la chambre intérieure 6 - on notera, en l'espèce, qu'il n'est effectué aucun apport d'air, contrairement à certains dispositifs connus visant à économiser l'eau -. On notera également que la partie supérieure 8a de l'axe central 8 maintient le moyen déflecteur 5 sur l'axe de symétrie de la chambre intérieure 6, grâce à un trou percé au centre de la crépine 3. La hauteur de cette chambre 6 est par ailleurs prévue de manière à procurer un léger jeu longitudinal au moyen déflecteur 5, retardant ainsi son entartrage qui serait plus rapide si ce déflecteur 5 était fixe.Furthermore, each of the blades 7 has an upper edge 7 a , the set of edges 7 a defining the same vertical plane (passing, in addition, through the central axis 8). In this way, the fluid having passed through the cylindrical strainer 3 slides over the vanes 7 which impart to this fluid a swirling movement, and mix it with the air contained in the interior chamber 6 - it will be noted, in this case, that no air is supplied, unlike certain known devices designed to save water. It will also be noted that the upper part 8 a of the central axis 8 maintains the deflector means 5 on the axis of symmetry of the interior chamber 6, thanks to a hole drilled in the center of the strainer 3. The height of this chamber 6 is also provided so as to provide a slight longitudinal clearance to the deflector 5, thus delaying its scaling which would be faster if this deflector 5 was fixed.

Selon la variante de l'invention représentée sur les figures 1 et 2, chaque aube 7 présente une échancrure inférieure 7b favorisant le regroupement des filets d'eau tourbillonnaires le long de l'axe central 8, qui se termine, par ailleurs, par une pointe 8b recomposant lesdits filets en un seul jet tourbillonnaire central, permettant de nourrir le jet en son centre.According to the variant of the invention shown in Figures 1 and 2, each blade 7 has a lower notch 7 b promoting the grouping of swirling water streams along the central axis 8, which ends, moreover, by a point 8 b recomposing said threads in a single central vortex jet, making it possible to feed the jet at its center.

Dans cette variante, la première chambre intérieure 6 est prolongée en aval par une deuxième chambre intérieure 9 tronconique, se rétrécissant progressivement vers le bas pour servir de logement à un ajutage amovible 10 destiné à augmenter la puissance du jet rendu tourbillonnaire, en amont, par le moyen déflecteur 5. Cet ajutage 10, qui accroît également la diffusion du jet, est calibré suivant le débit d'eau maximal désiré. Du fait qu'il soit monté amovible au fond de la chambre intérieure 9 tronconique, l'ajutage 10 peut être facilement remplacé, ce qui permet d'adapter son diamètre intérieur à la pression disponible sur le réseau de distribution d'eau.In this variant, the first interior chamber 6 is extended downstream by a second frustoconical interior chamber 9, tapering progressively downwards to serve as a housing for a removable nozzle 10 intended to increase the power of the jet rendered vortex, upstream, by the deflector means 5. This nozzle 10, which also increases the diffusion of the jet, is calibrated according to the maximum desired water flow rate. Because it is removably mounted at the bottom of the frustoconical inner chamber 9, the nozzle 10 can be easily replaced, which makes it possible to adapt its internal diameter to the pressure available on the water distribution network.

Dans la variante représentée sur les figures 3, 4 et 5, l'axe central 8 du moyen déflecteur 5 est alésé longitudinalement pour présenter la forme d'un tube laissant le passage à un flux d'eau central échappant au mouvement tourbillonnaire imprimé au flux périphérique par les aubes 7. Cette disposition permet également de nourrir le jet en son centre, le jet central non tourbillonnaire sortant au bas dudit tube se dirigeant vers l'ajutage amovible 10, également calibré suivant le débit d'eau maximal désiré. On notera que dans cette variante, la deuxième chambre intérieure 9 n'est pas tronconique mais simplement cylindrique, le moyen déflecteur 5 venant alors en appui sur un épaulement 11 séparant les deux chambres intérieures 6 et 9. Dans cette variante, l'ajutage 10 prend appui par un épaulement 10a sur une rive 9a ménagée autour d'un orifice prévu au centre et dans le fond de ladite chambre intérieure cylindrique 9.In the variant shown in Figures 3, 4 and 5, the central axis 8 of the deflector means 5 is bored longitudinally to have the shape of a tube allowing passage to a central flow of water escaping the swirling movement imparted to the flow peripheral by the vanes 7. This arrangement also makes it possible to feed the jet at its center, the non-vortex central jet exiting at the bottom of said tube going towards the removable nozzle 10, also calibrated according to the maximum desired water flow rate. Note that in this variant, the second interior chamber 9 is not frustoconical but simply cylindrical, the deflector means 5 then coming to bear on a shoulder 11 separating the two interior chambers 6 and 9. In this variant, the nozzle 10 is supported by a shoulder 10a on a bank 9 was provided around an orifice provided in the center and in the bottom of said cylindrical inner chamber 9.

Par ailleurs, il est à noter que l'alésage ménagé dans l'ajutage 10 peut soit, à la manière de la figure 1, se composer de deux parties tronconiques entourant une partie centrale cylindrique, déterminant son diamètre minimum (effet de Venturi), soit, à la manière de la figure 3, être constitué d'une unique partie cylindrique de diamètre constant.Furthermore, it should be noted that the bore formed in the nozzle 10 can either, in the manner of FIG. 1, consist of two frustoconical parts surrounding a cylindrical central part, determining its minimum diameter (Venturi effect), or, as in Figure 3, be made of a single cylindrical part of constant diameter.

Suivant l'invention, et d'une manière commune aux deux variantes précitées, un manchon 12 est monté coulissant sur la douille 2 et permet au jet tourbillonnaire intensifié sortant de l'ajutage 10 d'être plus ou moins largement diffusé par une plaque de sortie percée 12a formant la face avant dudit manchon 12.According to the invention, and in a manner common to the two abovementioned variants, a sleeve 12 is slidably mounted on the sleeve 2 and allows the intensified vortex jet coming out of the nozzle 10 to be more or less widely distributed by a plate of pierced outlet 12 a forming the front face of said sleeve 12.

Conformément au détail représenté sur la figure 1, cette plaque de sortie 12a comporte un trou central 13, préférentiellement circulaire ou oblong, qui est entouré de trous périphériques 14 plus petits et régulièrement répartis autour dudit trou central 13. Suivant l'invention, la plaque de sortie 12a possède une épaisseur suffisante pour que la paroi du trou central 13 constitue un guide pour le jet tourbillonnaire intensifié issu de l'ajutage 10. De cette façon, il existe une position du manchon 12 le long de la douille 2 pour laquelle le jet d'eau présente une ouverture angulaire minimale et une puissance maximale ; à l'inverse, lorsque, conformément aux demi-vues extérieures droites des figures 1 et 3, le manchon 12 se trouve en élongation maximale vers le bas, le jet tourbillonnaire intensifié issu de l'ajutage 10 peut atteindre les trous périphériques 14, faisant perdre sa puissance au jet liquide sortant de la plaque de sortie 12a. Dans cette position basse, le manchon 12 vient en butée, par une griffe annulaire 12b se trouvant en déport intérieur à son sommet, contre un épaulement annulaire 2b en saillie, ménagé à cet effet le long de la douille 2.According to the detail shown in Figure 1, this outlet plate 12 a has a central hole 13, preferably circular or oblong, which is surrounded by smaller peripheral holes 14 and regularly distributed around said central hole 13. According to the invention, the outlet plate 12 a has a thickness sufficient for the wall of the central hole 13 to constitute a guide for the intensified vortex jet coming from the 'nozzle 10. In this way, there is a position of the sleeve 12 along the sleeve 2 for which the water jet has a minimum angular opening and maximum power; conversely, when, in accordance with the right external half-views of FIGS. 1 and 3, the sleeve 12 is in maximum elongation downwards, the intensified vortex jet coming from the nozzle 10 can reach the peripheral holes 14, making lose its power with the liquid jet leaving the outlet plate 12 a . In this low position, the sleeve 12 abuts, by an annular claw 12 b being internally offset at its top, against an annular shoulder 2 b projecting, formed for this purpose along the sleeve 2.

Dans la variante représentée sur la figure 1, la douille 2 est cannelée, les cannelures 2c procurant des encoches annulaires successives coopérant avec la griffe annulaire 12b ; à cet égard, ladite griffe annulaire 12b peut être formée par une collerette continue, ou par une succession plus ou moins régulière d'ergots, le choix de réalisation de ladite griffe 12b dépendant de la fermeté de blocage que l'on veut obtenir. Une fois bloqué en position, le manchon 12 peut ainsi tourner librement autour de la douille 2, la griffe annulaire 12b se déplaçant avec peu de frottement dans la cannelure annulaire 2c dans laquelle elle se trouve. Dans cette même variante, la douille 2 est pourvue à son extrémité inférieure d'un alésage annulaire 2e qui coopère, pour le centrage du manchon 12, avec une bague annulaire 12c s'étendant vers l'intérieur dudit manchon 12 par rapport à la plaque de sortie percée 12a. Le guidage du manchon 12 est également assuré par le contact à frottement de sa paroi intérieure sur la paroi extérieure de ladite douille 2. Par ailleurs, selon une autre caractéristique de cette forme d'exécution de l'invention, la plaque de sortie percée 12a forme avec la bague 12c une pièce unique qui est rapportée à l'avant du manchon 12 après le vissage à force de la douille 2 sur le filetage extérieur 1a de la conduite d'eau 1. A cet effet, un logement 15, pouvant recevoir une clé de serrage (par exemple, une clé à six pans), est prévu sous l'ajutage 10, et contribue d'ailleurs à son maintien ; de cette manière, on peut visser à fond la douille 2 sur le filetage 1a, puis fermer le manchon 12 à son extrémité en collant, en enclipsant, ou encore de toute autre manière, la pièce formée par ladite plaque de sortie 12a et la bague 12c.In the variant shown in Figure 1, the sleeve 2 is grooved, the grooves 2 c providing successive annular notches cooperating with the annular claw 12 b ; in this respect, said annular claw 12 b can be formed by a continuous flange, or by a more or less regular succession of lugs, the choice of embodiment of said claw 12 b depending on the blocking firmness that one wants to obtain . Once locked in position, the sleeve 12 can thus rotate freely around the sleeve 2, the annular claw 12 b moving with little friction in the annular groove 2 c in which it is located. In this same variant, the sleeve 2 is provided at its lower end with an annular bore 2 e which cooperates, for the centering of the sleeve 12, with an annular ring 12 c extending towards the inside of said sleeve 12 relative to the drilled outlet plate 12 a . The guide of the sleeve 12 is also ensured by the friction contact of its inner wall on the outer wall of said socket 2. Furthermore, as another characteristic of this embodiment of the invention, the perforated outlet plate 12 to form with the ring 12 c a single piece which is attached to the front of the sleeve 12 after the screwing by force of the sleeve 2 on the external thread 1 a of the water pipe 1. For this purpose, a housing 15, capable of receiving a tightening key (for example, a hexagon wrench), is provided under the nozzle 10, and moreover contributes to its maintenance; in this way, it is possible to screw the bush 2 fully onto the thread 1 a , then close the sleeve 12 at its end by gluing, clipping, or in any other way, the part formed by said outlet plate 12 a and the ring 12c.

Dans une autre variante représentée sur la figure 3, la douille 2 est filetée plutôt que cannelée, les filets 2d coopérant alors avec la griffe annulaire 12b du manchon 12 qui peut alors être déplacé le long de la douille 2 par rotation. Néanmoins, il est prévu que la griffe annulaire 12b présente une élasticité suffisante pour que le manchon 12 puisse être simplement tiré le long de la douille 2, les filets 2d se comportant alors à la manière des cannelures 2c d'une douille 2 cannelée (figure 1). A cet égard, il est de toute manière évident que l'inclinaison des filets 2d d'une douille 2 filetée peut-être suffisamment faible pour que les différences avec un ensemble de cannelures 2c adjacentes soient négligeables. Dans cette variante, on a choisi un mode de montage différent du dispositif de douche : la plaque de sortie 12a forme ici une seule pièce avec le corps cylindrique 12d (fig.1) du manchon 12, un clip supérieur 16, du type d'un cylindre à linguets, venant s'emboîter dans l'espace ménagé à cet effet entre la paroi extérieure de la douille 2 et la paroi interne dudit corps cylindrique 2d ; un ergot annulaire 16a du clip 16 s'encastre alors dans une rainure 12e ménagée dans le corps cylindrique 12d du manchon 12 et empêche le retrait dudit clip 16, ledit manchon 12 présentant ainsi une forme extérieure similaire à celle proposée comme première variante à la figure 1. Le serrage de la douille 2 sur le filetage 1a de la conduite d'eau 1 ne s'obtient plus, dans ce cas, par le biais d'un logement pouvant recevoir une clé de serrage mais il est tout simplement prévu de réaliser deux trous 17 à l'avant de la douille 2, en vis-à-vis desquels on puisse amener deux trous périphériques 14 de la plaque de sortie percée 12a du manchon 12, un cavalier, non représenté sur les figures, pouvant alors être introduit au travers des trous 14 et 17 mis en coïncidence pour que la rotation dudit manchon 12 entraîne celle de la douille 2 intérieure qui peut ainsi être vissée sur la conduite d'eau 1.In another variant shown in Figure 3, the sleeve 2 is threaded rather than fluted, the threads 2 d then cooperating with the annular claw 12 b of the sleeve 12 which can then be moved along the sleeve 2 by rotation. However, it is expected that the annular claw 12 b has sufficient elasticity so that the sleeve 12 can be simply pulled along the sleeve 2, the threads 2 d then behaving in the manner of the grooves 2 c of a sleeve 2 grooved (Figure 1). In this regard, it is in any case obvious that the inclination of the threads 2 d of a threaded socket 2 may be sufficiently small so that the differences with a set of adjacent grooves 2 c are negligible. In this variant, a different mounting mode has been chosen for the shower device: the outlet plate 12 has here a single piece with the cylindrical body 12 d (fig. 1) of the sleeve 12, an upper clip 16, of the type a latch cylinder, which fits into the space provided for this purpose between the outer wall of the sleeve 2 and the inner wall of said cylindrical body 2 d ; an annular lug 16 a of the clip 16 then fits into a groove 12 e formed in the cylindrical body 12 d of the sleeve 12 and prevents the removal of said clip 16, said sleeve 12 thus having an external shape similar to that proposed as the first variant in FIG. 1. The tightening of the sleeve 2 on the thread 1 a of the water pipe 1 is no longer obtained, in this case, by means of a housing which can receive a tightening key, but it is quite simply planned to make two holes 17 at the front of the socket 2, opposite which two peripheral holes 14 of the drilled outlet plate 12 a of the sleeve 12 can be brought, a jumper, not shown in the Figures, which can then be introduced through holes 14 and 17 placed in coincidence so that the rotation of said sleeve 12 causes that of the inner sleeve 2 which can thus be screwed onto the water pipe 1.

On peut aussi munir les dispositifs de douche précédemment décrits d'une enveloppe protectrice, non représentée sur les dessins pour la clarté de ceux-ci, et ne laissant apparaître que l'extrémité du manchon 12.It is also possible to provide the shower devices described above with a protective envelope, not shown in the drawings for the sake of clarity, and leaving only the end of the sleeve 12 visible.

Le domaine de l'invention est celui des dispositifs à pomme d'arrosoir destinés à équiper, en particulier, les douches ou les douchettes.The field of the invention is that of sprinkler head devices intended to equip, in particular, showers or hand showers.
