Abstract

The joint is formed from two halves (1,2) which fit together and have an 'O'-ring seal (3) between them. One half (2) has a conical shear ring (22) attached to the main body by a section (25) of reduced diameter. The two halves are assembled with the 'O'-ring in position until the shear ring (22) makes contact with the face of the nut (12) of the other half joint (1). Further pressure (in the direction of the arrows 4) causes the ring (22) to shear at the junction (24) with the reduced section. Further pressure deforms the reduced section around the inner conical profile (23) of the shear ring and locks the two halves.

Description

On sait qu'afin de permettre à un élément de canalisation de pivoter par rapport à un autre en vue de faciliter une manoeuvre ou d'autoriser l'alignement automatique des deux éléments considérés, on fait fréquemment comporter aux tuyauteries des raccords tournants comprenant deux pièces tubulaires respectivement fixées à l'un et à l'autre des éléments, ces pièces étant emmanchées l'une dans l'autre avec interposition d'un joint comprimé entre des portées annulaires appropriées pour assurer ltétanchEité du raccordement pivotant ainsi obtenu.Il est bien entendu indispensable que les deux pièces constitutives soient axialement rendues solidaires l'une de l'autre et pour cet assemblage l'on a le plus souvent recours soit à la mise en place d'une troisième pièce séparée, soit à une opération de sertissage. It is known that in order to allow one pipe element to pivot relative to another in order to facilitate an operation or to authorize the automatic alignment of the two elements considered, the fittings are frequently made to comprise rotary fittings comprising two parts. tubular respectively fixed to one and to the other of the elements, these parts being fitted one inside the other with the interposition of a compressed seal between suitable annular bearing surfaces to ensure the tightness of the pivoting connection thus obtained. understood essential that the two component parts are axially made integral with one another and for this assembly we usually use either the establishment of a third separate part, or a crimping operation.

On conçoit que dans l'un et l'autre cas cet assemblage complique de maniera non négligeable la fabrication en grande série de ce type de raccords et c1 est à cet inconvénient que la présente invention entend principalement remédier. It will be understood that in both cases this assembly will make it not insignificant to manufacture mass production of this type of fittings and c1 is to this drawback that the present invention mainly intends to remedy.

L'invention consiste essentiellement à faire comporter à l'extrémité de l'une des deux pièces constitutives qui est tournée vers l'intérieur une levra cylindrique reliée par une zone amincie1 susceptible de- se rompre de manière relativement aisée, une bague terminale dont l'ouverture axiale présente un profil tronconique ouvert en direction de la zone amincie précitée.Une fois les deux pièces emmanchées avec interposition du joint d'étanchéité, il suffit d'exercer une pression axiale tendant à rapprocher lesdites pièces ; la bague terminale vient buter contre un épaulement prévu sur la pièce opposée, si bien que la zone amincie se rompt et que la levre s'engage dans cette ouverture qui par suite de son profil tronconique, forme guide pour l'extrémité de la levure, laquelle vient finalement se sertir à l'intérieur d'une gorge pratiquée en avant de l'épaulement sus-mentionné. The invention essentially consists in having at the end of one of the two constituent parts which is turned towards the inside a cylindrical levra connected by a thinned zone 1 capable of breaking relatively easily, a terminal ring whose l 'axial opening has a frustoconical profile open towards the aforementioned thinned area. Once the two parts fitted with interposition of the seal, it suffices to exert an axial pressure tending to bring said parts together; the end ring abuts against a shoulder provided on the opposite part, so that the thinned zone breaks and the lip engages in this opening which, as a result of its frustoconical profile, forms a guide for the end of the yeast, which is finally crimped inside a groove made in front of the above-mentioned shoulder.

L'opération d'assemblage ne nécessite donc qu'une simple pression axiale susceptible d'être exercée å l'aide d'appareillages simples, aptes à fonctionner à des cadences élevées. The assembly operation therefore requires only a simple axial pressure capable of being exerted with the aid of simple apparatuses, capable of operating at high rates.

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 montrant les deux pièces constitutives d'un raccord tournant suivant l'invention, ces pièces étant représentées après emmanchement mais avant l'opération d'assemblage.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 an axial section showing the two constituent parts of a rotary connector according to the invention, these parts being shown after fitting but before the assembly operation.

Fig. 2 reproduit fig. 1, le raccord étant montré à l'état fini. Fig. 2 reproduced fig. 1, the connector being shown in the finished state.

Le raccord tournant considéré est constitué par l'assemblage de deux pièces tubulaires 1 et 2 emmanchées l'une a l'intérieur de l'autre avec interposition d'un joint d'étanchéité 3. Ce dernier est maintenu entre des portées annulaires 10 et 20 respectivement ménagées sur la paroi extérieure de la pièce 1 et sur la paroi intérieure de la pièce 2. The considered rotary coupling consists of the assembly of two tubular parts 1 and 2 fitted one inside the other with the interposition of a seal 3. The latter is held between annular bearings 10 and 20 respectively formed on the outer wall of the part 1 and on the inner wall of the part 2.

Cette pièce 2 comporte, à l'apposé de son extrémité 21 destinée à être rendue solidaire de l'un des deux éléments de canalisation à raccorder, une bague terminale 22 dont 11 ouverture axiale 23 est établie à un profil tronconique ouvert en direction de ladite extrémité 21. This part 2 comprises, at the apposition of its end 21 intended to be made integral with one of the two pipe elements to be connected, an end ring 22 of which 11 axial opening 23 is established at a frustoconical profile open in the direction of said end 21.

Cette bague 22 se raccorde par une zone transversale amincie 24 à une levre cylindrique 25 dont le diamètre extérieur est substantiellement égal au diamètre intérieur du débouché évasé de l'ouverture 22 susmentionnée. La lèvre 25 est directement solidaire de la partie à plus fort diamètre de la pièce 2.This ring 22 is connected by a thinned transverse zone 24 to a cylindrical lip 25 whose outside diameter is substantially equal to the inside diameter of the flared outlet of the abovementioned opening 22. The lip 25 is directly integral with the larger diameter part of the part 2.

La pièce 1 présente une extrémité 11 agencéè pour permettre sa fixation en bout du second élément de canalisation à raccorder. En avant de cette extrémité 11 la pièce 1 comporte un épaulement -12 dont le diamètre est supérieur à celui de la bague terminale 22 de la pièce 2. The part 1 has an end 11 arranged to allow its fixing at the end of the second pipe element to be connected. In front of this end 11 the part 1 has a shoulder -12 whose diameter is greater than that of the end ring 22 of the part 2.

Cet épaulement 12 est lui-mema précédé par une gorge 13, séparée de la portée 10 par un redan annulaire 14.This shoulder 12 is itself preceded by a groove 13, separated from the bearing surface 10 by an annular step 14.

En fig. 1 les deux pièces 1 et 2 ont été représentées à l'état simplement emmanché, la pénétration de la pièce 1 à l'intérieur de la pièce 2 étant limitée par portée de la bague 22 contre l'épaulement 12. In fig. 1 the two parts 1 and 2 have been shown in the simply fitted state, the penetration of the part 1 inside the part 2 being limited by the bearing of the ring 22 against the shoulder 12.

Pour opérer l'assemblage axial des deux pièces il suffit d'exercer sur elles une pression axiale (flèches 4) tendant à les rapprocher l'une de l'autre.To operate the axial assembly of the two parts, it suffices to exert an axial pressure on them (arrows 4) tending to bring them closer to one another.

Commme montré en fig. 2 la zone amincie 24 se rompt et le bord ainsi découvert de la levre cylindrique 25 glisse le long de la paroi de l'ouverture 23. Par suite du--profil évasé de cette paroi la levre 25 est contrainte de se replier progressivement vers l'intérieur en occupant l'espace ménagé par la gorge 13 de la pièce l, de telle sorte qu'on obtient finalement, en une seule opération de presse, le sertissage des deux pièces ; on notera que la bague 22 s'oppos#e à tout redressement intempestif de la levre 25, si bien que l'assemblage est définitif. As shown in fig. 2 the thinned zone 24 breaks and the thus uncovered edge of the cylindrical lip 25 slides along the wall of the opening 23. As a result of the - flared profile of this wall the lip 25 is forced to gradually fold back towards the 'interior occupying the space provided by the groove 13 of the part l, so that one finally obtains, in a single press operation, the crimping of the two parts; note that the ring 22 opposes # e any untimely recovery of the lip 25, so that the assembly is final.

On conçoit que l'emmanchement de deux pièces 1 et 2 après mise enplace du joint 3 est susceptible d'être effectué de manière aisée à l'aide d'appareillages de montage fonctionnement automatique. La finition des raccords tournants nécessite uniquement le rapprochement à force des deux pièces emmanchées et ici encore l'on peut avoir recours à des appareillages simples à cadence de fonctionnement élevée. It will be appreciated that the fitting of two parts 1 and 2 after the joint 3 has been put in place can be carried out easily using automatic operating mounting apparatus. Finishing the rotary couplings only requires forcing the two pressed-in parts together and here again, simple apparatus can be used with a high operating rate.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
