On connaít de nombreux exemples d'élément de raccord de plomberie de ce type.Numerous examples of connection elements are known from plumbing of this type.

Le document EP-A1-0.429.292 décrit et représente un système de compteur d'eau et de robinet d'arrêt comportant des éléments tubulaires télescopiques orientés suivant une première direction axiale. Un tube extérieur est destiné à recevoir à une de ses extrémités un logement destiné à recevoir un bloc comportant un corps destiné à recevoir un montage de compteur d'eau et une vanne anti-retour. Le corps est réalisé en deux parties. Une partie comporte une première pipe qui comporte un premier orifice de raccordement, et l'autre partie comporte une seconde pipe qui comporte un second orifice de raccordement. Chaque pipe est articulée par rapport au bloc autour d'au moins une seconde direction axiale sécante à la direction générale du bloc. En particulier, chaque pipe comporte un tronçon d'articulation qui pénètre de manière tournante dans un tronçon d'articulation de chaque partie associée au bloc. A cet effet, chaque tronçon d'articulation de chaque pipe comporte une collerette dont une face transversale est en appui plan sur une face d'une collerette du tronçon d'articulation de la partie associée. La collerette comporte une portée cylindrique qui est reçue dans une portée cylindrique faisant saillie à partie de la face transversale de la collerette de la partie de bloc associée, et les portées cylindriques sont immobilisées extérieurement par un anneau de maintien indépendant.EP-A1-0.429.292 describes and represents a water meter and shut-off valve system including telescopic tubular elements oriented according to a first axial direction. An outer tube is intended to accommodate one of its ends a housing for receiving a block comprising a body for receiving a water meter assembly and a check valve. The body is made in two parts. A part has a first pipe that has a first port of connection, and the other part has a second pipe that has a second connection port. Every pipe is articulated with respect to the block around at least a second axial direction secant to the general direction of the block. In particular, each pipe has a hinge section which penetrates in a rotating manner into a hinge section of each part associated with the block. For this purpose, each section each pipe has a flange, one of which transverse face is in plane support on a face of a collar articulation section of the associated part. The collar has a cylindrical scope that is received in a scope cylindrical projecting from the transverse face of the flange of the associated block portion, and staves cylindrical are immobilized externally by a ring of independent maintenance.

Le guidage en rotation au niveau du raccordement du bloc et de chaque extrémité libre est donc assuré par la rotation des extrémités libres tubulaires dans chaque partie elle aussi tubulaire, celles-ci étant maintenues extérieurement par l'anneau de maintien.Rotation guidance at the block connection and of each free end is thus ensured by the rotation of tubular free ends in each part too tubular, these being held externally by the ring keeping.

Les deux pipes sont agencées à la même extrémité du système de compteur d'eau et de robinet d'arrêt, et sont donc très proches les unes des autres ce système étant destiné à servir de compteur d'eau en étant intercalé dans une installation déjà existante.The two pipes are arranged at the same end of the water meter and stopcock system, and so are very close to each other this system being intended to serve of water meter being interposed in a facility already existing.

On a représenté aux figures 1 et 2 deux modes de réalisation d'un élément 10 de raccord de plomberie.FIGS. 1 and 2 show two modes of realization of a plumbing fitting element 10.

L'élément 10 de raccord de plomberie comporte au moins un corps 12 sensiblement tubulaire orienté suivant une première direction axiale générale A. L'élément 10 comporte une première extrémité libre 14 tubulaire qui comporte un premier orifice 16 de raccordement, et il comporte une seconde extrémité libre 18 opposée qui comporte un second orifice de raccordement 20.Plumbing fitting element 10 has at least one substantially tubular body 12 oriented in a first general axial direction A. The element 10 has a first tubular free end 14 which comprises a first connection orifice 16, and it comprises a second free end 18 opposite which comprises a second connection port 20.

De manière connue, l'extrémité libre 14 tubulaire est par exemple taraudée intérieurement de manière à permettre le vissage d'un conduit fileté d'usage conventionnel en plomberie.In a known manner, the tubular free end 14 is example tapped internally so as to allow the screwing a conventional threaded conduit into plumbing.

D'une manière analogue, l'extrémité libre 18 tubulaire est par exemple filetée extérieurement de manière à permettre son vissage dans un conduit taraudé d'usage conventionnel en plomberie.In a similar manner, the tubular free end 18 is for example threaded externally so as to allow its screwing in a conventional threaded duct in plumbing.

A titre d'exemple et de manière non limitative de l'invention, le premier orifice 16 est par exemple un conduit de sortie d'eau et le second conduit 20 est par exemple un conduit d'arrivée d'eau. La première extrémité libre 14 tubulaire est par exemple coudée à angle droit de manière à permettre le branchement du premier orifice au dos d'un élément sanitaire tel qu'un urinoir. By way of example and without limitation, the invention, the first orifice 16 is for example a conduit of water outlet and the second conduit 20 is for example a conduit water supply. The first tubular free end 14 is example bent at a right angle so as to allow the connecting the first port to the back of a sanitary element such than a urinal.

De manière connue, une vanne 22 est interposée dans le corps tubulaire 12 entre les premier et second orifices 16, 18 de raccordement.In known manner, a valve 22 is interposed in the tubular body 12 between the first and second ports 16, 18 of connection.

Dans le mode de réalisation préféré de l'invention, et de manière non limitative de celle-ci, la vanne 22 est par exemple constituée d'une électrovanne de type tout ou rien, notamment une électrovanne conventionnelle dont un tiroir interne (non représenté) est actionné par un solénoïde dont l'ouverture est commandée par un module électronique associé à un capteur optique (non représentés). Le module électronique est alimenté par pile ou par secteur.In the preferred embodiment of the invention, and non-limiting way thereof, the valve 22 is for example consisting of an all-or-nothing solenoid valve, in particular a conventional solenoid valve including an internal drawer (no shown) is actuated by a solenoid whose opening is controlled by an electronic module associated with a sensor optical (not shown). The electronic module is powered by battery or by sector.

Conformément à l'invention, l'élément 10 de raccord de plomberie comporte un tronçon tubulaire 24, articulé par rapport au corps 12 autour d'au moins une seconde direction axiale B sécante à la première direction générale A du corps 12, dont l'extrémité libre forme la seconde extrémité libre 18 de l'élément 12 de raccord, pour permettre le raccordement du second orifice 20 suivant au moins une direction C différente de la direction axiale A générale du corps 12.According to the invention, the connecting element 10 of plumbing comprises a tubular section 24 articulated relative to at the body 12 around at least a second axial direction B secante at the first general direction A of the body 12, whose the free end forms the second free end 18 of the element 12 of connection, to allow the connection of the second orifice 20 following at least one direction C different from the direction axial A general of the body 12.

Dans le premier mode de réalisation qui est représenté à la figure 1, le tronçon tubulaire 24 est rectiligne et il est articulé autour d'une seconde direction axiale B qui est perpendiculaire à la première direction générale A du corps 12. De ce fait, la direction B d'articulation et la direction C du second orifice 20 sont confondues. Le tronçon tubulaire 24 permet donc le raccordement du second orifice 20 perpendiculairement à la direction axiale A générale du corps 12.In the first embodiment which is represented at 1, the tubular section 24 is rectilinear and is articulated around a second axial direction B which is perpendicular to the first general direction A of the body 12. As a result, the articulation direction B and the direction C of the second orifice 20 are confused. The tubular section 24 thus allows the connecting the second orifice 20 perpendicular to the axial direction A general of the body 12.

Dans le second mode de réalisation, le tronçon tubulaire 24 est coudé à angle droit, et il est articulé autour d'une seconde direction axiale B qui est perpendiculaire à la première direction générale A du corps 12. La direction C du second orifice 20 étant perpendiculaire à la direction d'articulation B, le tronçon tubulaire 24 permet donc, en fonction de la position angulaire de son articulation, le raccordement du second orifice 20 suivant au moins une direction C située dans un plan parallèle à la direction axiale A générale du corps 12.In the second embodiment, the tubular section 24 is bent at a right angle, and it is articulated around a second axial direction B which is perpendicular to the first direction of the body 12. The direction C of the second orifice 20 being perpendicular to the articulation direction B, the tubular section 24 allows, depending on the angular position of his articulation, the connection of the next second orifice 20 to the minus a direction C located in a plane parallel to the direction axial A general of the body 12.

Avantageusement, le tronçon tubulaire 24 associé au premier mode de réalisation et le tronçon tubulaire 24 associé au second mode de réalisation sont interchangeables.Advantageously, the tubular section 24 associated with the first embodiment and the tubular section 24 associated with the second embodiment are interchangeable.

Il sera compris que cette disposition n'est pas limitative des deux modes de réalisation de l'invention, et que la seconde direction B d'articulation pourrait ne pas être perpendiculaire avec la première direction générale A du corps, mais former un angle déterminé avec celle-ci.It will be understood that this provision is not limiting of the two embodiments of the invention, and that the second articulation direction B might not be perpendicular with the first general direction A of the body but form an angle determined with it.

D'une manière analogue, il sera compris que, de manière non limitative du second mode de réalisation de l'invention, la direction C du second orifice 20 pourrait n'être pas perpendiculaire à la direction d'articulation B, mais former un angle aigu ou obtu déterminé avec celle-ci.In a similar way, it will be understood that, so non-limiting of the second embodiment of the invention, the direction C of the second orifice 20 may not be perpendicular to the articulation direction B but form a acute angle or obtuate determined with it.

Dans chacun des modes de réalisation, le tronçon tubulaire 24 comporte une extrémité 26 intermédiaire d'articulation, opposée à son extrémité libre 18, qui est munie d'une collerette 28 annulaire dont une face transversale 30 est montée tournante au contact d'une face transversale 32 d'une collerette annulaire 34 complémentaire qui est portée par une extrémité 36 d'articulation du corps 12.In each of the embodiments, the tubular section 24 has an intermediate hinge end 26, opposite its free end 18, which is provided with a collar 28 annular including a transverse face 30 is rotatably mounted in contact with a transverse face 32 of an annular flange 34 complementary which is carried by one end 36 of articulation of the body 12.

Ainsi, l'extrémité 26 intermédiaire d'articulation, montée tournante autour de l'axe B perpendiculaire à la première direction axiale A générale du corps, permet l'articulation du tronçon tubulaire 24.Thus, the intermediate end 26 of articulation, mounted rotating around the B axis perpendicular to the first axial direction A general body, allows the articulation of the tubular section 24.

Plus particulièrement, la collerette annulaire 28 de l'extrémité intermédiaire 26 d'articulation du tronçon tubulaire 24 comporte une gorge annulaire 38 qui débouche dans sa face transversale 30 et qui est destinée à recevoir une portion tubulaire 40 complémentaire faisant saillie à partir de la face transversale 32 de la collerette annulaire 34 portée par l'extrémité 36 d'articulation du corps 12. More particularly, the annular flange 28 of the intermediate end 26 of articulation of the tubular section 24 has an annular groove 38 which opens into its face transverse 30 and which is intended to receive a portion tubular 40 complementary projecting from the face transverse 32 of the annular collar 34 carried by the end 36 of articulation of the body 12.

Par ailleurs, l'élément de raccord 12 comporte des moyens de serrage des collerettes annulaire 28 et 34 l'une contre l'autre, notamment pour de garantir une bonne étanchéité de l'élément de raccord 12 lorsqu'il est traversé par un flux d'eau.Moreover, the connecting element 12 comprises means clamping the annular flanges 28 and 34 against each other, especially to ensure a good seal of the element of connector 12 when traversed by a stream of water.

L'élément de raccord 12 comporte aussi des moyens d'immobilisation angulaire des collerettes annulaires 28, 34 l'une par rapport à l'autre, et moyens d'indexation de la position angulaire des collerettes annulaires 28, 34 l'une par rapport à l'autre.The connecting element 12 also comprises means angular immobilization of the annular flanges 28, 34 one relative to each other, and means for indexing the position angle of the annular flanges 28, 34 with respect to the other.

Cette disposition est particulièrement avantageuse puisqu'elle permet, en particulier dans le cadre du second mode de réalisation qui a été représenté à la figure 2, de mettre en position de manière précise le tronçon tubulaire 24 par rapport au corps 12 et de le maintenir dans cette position, avant d'assurer l'étanchéité de l'élément de raccord 12 à l'aide des moyens de serrage.This arrangement is particularly advantageous since it allows, especially in the context of the second mode implementation shown in Figure 2, to implement position accurately the tubular section 24 relative to the 12 and maintain it in that position, before ensuring sealing of the connecting element 12 by means of Tightening.

De préférence, les moyens d'immobilisation, d'indexation, et de serrage sont constitués d'au moins deux vis (non représentées) réparties angulairement à intervalles réguliers qui traversent les collerettes annulaires 28, 34. A cet effet, comme l'illustrent les figures 3 à 6, la collerette annulaire 34 comporte par exemple quatre perçages 42 répartis angulairement à 90 degrés les uns des autres, et qui sont destinés à recevoir des vis (non représentées) qui peuvent être vissées dans quatre perçages correspondants (non représentés) de la collerette annulaire 28.Preferably, the means of immobilization, indexing, and clamping consist of at least two screws (no represented) angularly distributed at regular intervals through the annular flanges 28, 34. For this purpose, as 3 to 6, the annular flange 34 comprises for example four holes 42 angularly distributed at 90 degrees from each other, and which are intended to receive screws (not shown) that can be screwed into four corresponding holes (not shown) of the collar annular 28.

Cette configuration permet, dans le cadre du premier mode de réalisation qui a été représenté à la figure 1, d'assurer la fixation du tronçon tubulaire 24 suivant sa position unique.This configuration allows, as part of the first mode embodiment which has been shown in FIG. fixing the tubular section 24 according to its unique position.

Cette configuration est de plus particulièrement avantageuse, puisqu'elle permet, dans le cadre du second mode de réalisation qui a été représenté aux figures 2 à 6, d'orienter le tronçon tubulaire 24 suivant quatre positions différentes représentées aux figures 3 à 6. This configuration is more particularly advantageous, since it allows, in the context of the second embodiment shown in FIGS. 2 to 6, to orient the tubular section 24 according to four different positions shown in Figures 3 to 6.

Ainsi, comme l'illustre la figure 3, la direction C de l'orifice 20 peut être orientée suivant deux positions opposées, représentées aux figures 3 et 5, qui sont parallèles à la direction générale A du corps 12, ou suivant deux suivant deux positions opposées représentées aux figures 4 et 6, qui sont perpendiculaires à la direction générale A du corps 12, suivant la position initiale de montage du tronçon tubulaire 24.Thus, as illustrated in FIG. 3, the direction C of the orifice 20 can be oriented in two opposite positions, shown in Figures 3 and 5, which are parallel to the direction general A of the body 12, or following two according to two positions opposites shown in Figures 4 and 6, which are perpendicular to the general direction A of the body 12, according to initial position of assembly of the tubular section 24.

Il sera compris qu'un nombre supérieur de vis et de perçages associés répartis angulairement de manière régulière sur les collerettes 28, 34 offrirait un plus grand nombre de positions.It will be understood that a higher number of screws and associated holes distributed angularly on a regular basis on the collars 28, 34 would offer a greater number of positions.

Il sera aussi compris que l'on pourrait envisager l'utilisation de moyens d'immobilisation, d'indexation, et de serrage différents, tels qu'un collier (non représenté) à gorge conique monté extérieurement sur une périphérie conique des collerettes 28, 34. Un tel collier permettrait de mettre en position le tronçon tubulaire 24 suivant un nombre élevé de positions établies avant le serrage dudit collier.It will also be understood that one could consider the use of means of immobilization, indexing, and different clamping arrangements, such as a collar (not shown) taper mounted externally on a conical periphery of flanges 28, 34. Such collar would put in position the tubular section 24 following a large number of positions established before tightening said collar.

Avantageusement, comme l'illustre la figure 3, le corps 12 comporte, en amont de l'électrovanne 22, un filtre (non représenté) qui est interposé entre son extrémité d'articulation et la vanne 22. Le filtre est par exemple logé dans un alésage 44 qui est formé dans un bossage 46 venu de matière avec le corps 12, qui est fermé par un bouchon 48, et qui communique avec l'électrovanne 22. Par ailleurs, comme l'illustrent les figures 1 et 2, le corps 12 comporte un robinet de régulation de débit qui est interposé entre son extrémité d'articulation 36 et le filtre qui est logé dans l'alésage 44. Le robinet est par exemple formé d'un pointeau qui est reçu dans un alésage 50 qui communique avec l'alésage 44.Advantageously, as illustrated in FIG. 3, the body 12 comprises, upstream of the solenoid valve 22, a filter (no shown) which is interposed between its articulation end and the valve 22. The filter is for example housed in a bore 44 which is formed in a boss 46 integral with the body 12, which is closed by a plug 48, and which communicates with the solenoid valve 22. Moreover, as illustrated in FIGS. 2, the body 12 includes a flow control valve which is interposed between its hinge end 36 and the filter which is housed in the bore 44. The valve is for example formed of a needle which is received in a bore 50 that communicates with the bore 44.

Enfin, l'élément 10 peut être fixé à au moins un support extérieur d'une part par l'intermédiaire de vis (non représentées) traversant des perçages 52 d'oreilles 54 qui s'étendent radialement à partir de la première extrémité libre 14 et d'autre part par l'intermédiaire de vis (non représentées) traversant des perçages 56 d'oreilles 58 d'un collier 60 monté autour du tronçon tubulaire 24.Finally, the element 10 can be attached to at least one support outside on the one hand by means of screws (not shown) traversing pierces 52 ears 54 which extend radially from the first free end 14 and other through screws (not shown) passing through holes 56 of ears 58 of a collar 60 mounted around the section tubular 24.

L'invention permet donc de disposer d'un élément de raccord de plomberie pouvant être adapté à de nombreuses configuration de montage.The invention therefore makes it possible to have an element of Plumbing fitting that can be adapted to many mounting configuration.
