A sleeve (3) with a shoulder (13) passes over the keys (5) to hold the whole unit in a locked position.

Description

RACCORD TOURNANT. TURNING JOINT.

La présente invention a pour objet un raccord tournant destiné en particulier, mais non exclusivement aux extincteurs d'incendies.The subject of the present invention is a rotary connector intended in particular, but not exclusively, for fire extinguishers.

Différents types de raccords tournants, notamment en laiton, ont déjà été proposés. Ils comprennent d'une manière générale, une pièce femelle à l'intérieur de laquelle est introduit un embout mâle, un joint torique étant interposé entre les deux pièces de sorte que celles-ci puissent tourner l'une par rapport à l'autre tout en conservant l'étanchéité de la liaison. Un moyen est prévu pour éviter un mouvement axial d'une pièce par rapport à l'autre, ce moyen consistant fréquemment en un jonc de blocage. Dans la plupart des cas, ces raccords sont démontables de sorte qu'il est possible de séparer les organes réunis par le raccord. Mais les raccords connus, comprenant un grand nombre de pièces, sont généralement d'un montage compliqué.Various types of rotary couplings, in particular brass, have already been proposed. They generally include a female part inside which is inserted a male end piece, an O-ring being interposed between the two parts so that they can rotate relative to each other while maintaining the tightness of the connection. Means are provided to avoid axial movement of one part with respect to the other, this means frequently consisting of a locking rod. In most cases, these fittings are removable so that it is possible to separate the members joined by the fitting. However, the known fittings, comprising a large number of parts, are generally of complicated assembly.

Un objet de l'invention est de pallier cet inconvénient et de permettre un montage instantané et indémontable du raccord en matière plastique.An object of the invention is to overcome this drawback and to allow instant and non-removable mounting of the plastic connection.

Un second objet de l'invention est la réalisation d'un raccord haute pression qui soit taré pour que le raccord soit rompu dès qu'une pression déterminée, par exemple 80 bars, est atteinte.A second object of the invention is the production of a high pressure fitting which is calibrated so that the fitting is broken as soon as a determined pressure, for example 80 bars, is reached.

Selon l'invention, le raccord tournant comprenant une pièce ou embout femelle, à l'intérieur de laquelle pénètre une pièce ou embout mâle, un joint étant interposé entre la pièce femelle et l'embout mâle, est caractérisé en ce que le raccord est verrouillé par un manchon encliquetable.According to the invention, the rotary connector comprising a female part or end piece, inside which a male part or end part penetrates, a seal being interposed between the female part and the male end piece, is characterized in that the connector is locked by a snap-on sleeve.

Le verrouillage des deux pièces est ainsi obtenu par glissement du manchon sur une partie de la surface externe de l'embout mâle. The locking of the two parts is thus obtained by sliding the sleeve over a part of the external surface of the male end piece.

Selon une autre caractéristique de l'invention, le blocage axial des deux pièces est réalisé par au moins une clavette qui pénètre dans une fente de la pièce femelle et dans une rainure circulaire de la pièce mâle, la clavette étant verrouillée par ledit manchon encliquetable.According to another characteristic of the invention, the axial locking of the two parts is achieved by at least one key which enters a slot in the female part and in a circular groove in the male part, the key being locked by said snap-on sleeve.

L'ensemble est ainsi bloqué en position axiale mais les deux pièces peuvent tourner l'une par rapport à l'autre. De plus, il ne peut pas tre démonté en raison de l'encliquetage du manchon extérieur.The assembly is thus locked in the axial position but the two parts can rotate relative to each other. Furthermore, it cannot be dismantled due to the snap-fastening of the outer sleeve.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard des dessins qui représentent :
-la figure 1, une vue éclatée d'un raccord selon
l'invention ;
-la figure 2, une vue en coupe du mme raccord. ;
-la figure 3, une vue une vue de détail du montage des
clavettes.
Other characteristics and advantages of the invention will appear during the following description of a particular embodiment, given solely by way of nonlimiting example, with reference to the drawings which represent:
FIG. 1, an exploded view of a connector according to
the invention;
FIG. 2, a sectional view of the same fitting. ;
FIG. 3, a view a detailed view of the mounting of the
keys.

Sur l'ensemble des figures, les mmes références désignent les mmes éléments. L'exemple représenté concerne un raccord tournant droit, mais l'invention s'applique, bien entendu, aux raccords tournants coudés. L'ensemble des pièces qui seront décrites ci-dessous est en matière plastique.Throughout the figures, the same references designate the same elements. The example shown relates to a straight swivel fitting, but the invention applies, of course, to elbow swivel fittings. All the parts which will be described below are made of plastic.

Comme cela apparaît sur la figure 1, l'embout femelle 1 présente une extrémité filetée se prolongeant par une bague polygonale 9 destinée à permettre le vissage dans un appareil quelconque. L'extrémité opposée au filetage par rapport à la bague polygonale 9 est cylindrique et présente deux fentes radiales 6, diamétralement opposées, destinées à permettre l'introduction de deux clavettes 5.As shown in Figure 1, the female endpiece 1 has a threaded end extending by a polygonal ring 9 intended to allow screwing in any device. The end opposite the thread with respect to the polygonal ring 9 is cylindrical and has two radial slots 6, diametrically opposite, intended to allow the introduction of two keys 5.

La pièce 2 ou embout mâle est également creuse et de forme générale cylindrique. Elle comprend une première partie destinée à tre insérée à l'intérieur de la pièce 1, séparée d'une partie extérieure, légèrement conique, par une bague 11. La partie avant comporte deux rainures circulaires. La rainure 8 est destinée à servir de siège à un joint torique 4. La seconde rainure 7 est destinée à recevoir la partie intérieure des clavettes 5, après leur insertion dans les fentes 6. La partie externe, légèrement tronconique présente des nervures circulaires 12 dissymétriques présentant une face inclinée par rapport à l'axe de la pièce 2 et une face perpendiculaire à cet axe, permettant, comme connu en soi, d'assujettir un tuyau souple sur cette extrémité.The part 2 or male end piece is also hollow and of generally cylindrical shape. It comprises a first part intended to be inserted inside the part 1, separated from an outer part, slightly conical, by a ring 11. The front part comprises two circular grooves. The groove 8 is intended to serve as a seat for an O-ring 4. The second groove 7 is intended to receive the internal part of the keys 5, after their insertion into the slots 6. The external part, slightly frustoconical, has asymmetrical circular ribs 12 having a face inclined relative to the axis of the part 2 and a face perpendicular to this axis, allowing, as known per se, to subject a flexible pipe to this end.

La pièce 3 constitue un manchon venant s'adapter sur les pièces 1 et 2 après leur assemblage. Son diamètre intérieur est sensiblement égal au diamètre extérieur de la pièce 1, du côté interne de celle-ci, qu'il entoure après montage.The part 3 constitutes a sleeve which fits on the parts 1 and 2 after their assembly. Its internal diameter is substantially equal to the external diameter of the part 1, on the internal side of the latter, which it surrounds after mounting.

La figure 2 représente en coupe le raccord monté. Les pièces 1 et 2 sont percées chacune d'un alésage central 10 correspondant. On voit que la pièce 3 comporte un collet 13 qui est de diamètre inférieur au diamètre extérieur des nervures 12. En matière plastique, le collet peut se déformer légèrement pour passer successivement sur les nervures 12 jusqu'à ce qu'il vienne en butée contre la bague 11 de la pièce 2 lorsque le manchon 3 est poussé en direction de la pièce 1. Le collet 13 est alors emprisonné entre la dernière nervure 12 et la bague 11 de la pièce 2, ce qui empche tout démontage en raison de la dissymétrie des nervures 12, sauf à découper le collet 13. Les clavettes 5 sont ainsi verrouillées en direction radiale dans leur logement 6 et dans la rainure 7. Le manchon 3 ne joue aucun rôle dans la fixation axiale des pièces 1 et 2 et n'a pour but que de verrouiller les clavettes 5 à l'intérieur de leurs logements 6,8.Figure 2 shows in section the mounted fitting. Parts 1 and 2 are each pierced with a corresponding central bore 10. We see that the part 3 has a collar 13 which is of diameter smaller than the outside diameter of the ribs 12. In plastic material, the collar can be slightly deformed to pass successively over the ribs 12 until it comes into abutment against the ring 11 of the part 2 when the sleeve 3 is pushed towards the part 1. The collar 13 is then trapped between the last rib 12 and the ring 11 of the part 2, which prevents any disassembly due to the asymmetry ribs 12, except for cutting the collar 13. The keys 5 are thus locked in the radial direction in their housing 6 and in the groove 7. The sleeve 3 plays no role in the axial fixing of the parts 1 and 2 and has for the purpose of locking the keys 5 inside their housings 6.8.

La résistance axiale à la séparation des pièces 1 et 2 est obtenue uniquement par les clavettes 5 qui, comme cela apparaît mieux sur la vue de détail de la figure 3 sont insérées pour moitié de leur hauteur dans la fente 6 de la pièce 1 et, pour l'autre moitié, dans la rainure 7 de la pièce 2. Les clavettes en matière plastique travaillent en cisaillement. Bien entendu, la clavettes 5 ont une section transversale rectangulaire, mais présente une forme en secteur de cercle en direction longitudinale pour pénétrer et pouvoir tourner dans la rainure 7 et ainsi autoriser une rotation relative des deux pièces. Etant donné que seules les clavettes 5 assurent la solidarisation des deux pièces en direction axiale il est possible en agissant sur le choix de leur matière et sur leur épaisseur de les calibrer pour qu'elles jouent leur rôle de sécurité en cas de pression supérieure à une valeur déterminée.The axial resistance to separation of the parts 1 and 2 is obtained only by the keys 5 which, as appears better on the detail view of FIG. 3, are inserted for half their height in the slot 6 of the part 1 and, for the other half, in the groove 7 of the part 2. The plastic keys work in shear. Of course, the keys 5 have a rectangular cross section, but has a shape in a sector of a circle in the longitudinal direction in order to penetrate and be able to rotate in the groove 7 and thus allow a relative rotation of the two parts. Since only the keys 5 ensure the joining of the two parts in the axial direction it is possible by acting on the choice of their material and on their thickness to calibrate them so that they play their safety role in the event of pressure greater than one determined value.

Il va de soi que de nombreuses variantes peuvent tre apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de l'invention. It goes without saying that numerous variants can be made, in particular by substitution of equivalent technical means, without departing from the scope of the invention.
