Description

"Collier pour le raccordement amovible de deux canalisations"."Collar for the removable connection of two pipes".

Le collier de l'invention comprend deux demi-colliers rigides articulés l'un sur l'autre par une de leurs extrémités et comportant un moyen de serrage à leur autre extrémité, ces demi-colliers étant pourvus d'une rainure propre à chevaucher les collerettes prévues aux extrémités des deux canalisations à raccorder, dispositif caractérisé en ce que l'articulation des demi-colliers est fixée sur l'une des canalisations à raccorder, les deux demi-colliers étant situés dans le plan de raccordement. The collar of the invention comprises two rigid half-collars articulated one on the other by one of their ends and comprising a tightening means at their other end, these half-collars being provided with a groove suitable for overlapping the flanges provided at the ends of the two pipes to be connected, device characterized in that the articulation of the half-collars is fixed on one of the pipes to be connected, the two half-collars being located in the connection plane.

Suivant une autre caractéristique de l'invention, un moyen élastique est prévu entre les deux demi-colliers pour tendre à les rapprocher l'un de l'autre. According to another characteristic of the invention, an elastic means is provided between the two half-collars to tend to bring them closer to one another.

Suivant une autre caractéristique de l'invention, les deux demi-colliers présentent une surface inclinée sur leur face latérale située à l'opposé de la canalisation qui les supporte, ces surfaces étant inclinées vers l'intérieur de cette canalisation. According to another characteristic of the invention, the two half-collars have an inclined surface on their lateral face situated opposite the pipe which supports them, these surfaces being inclined towards the inside of this pipe.

L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels
- la figure 1 est une vue axiale partiellement coupée du dispositif conforme à l'invention,
- la figure 2 est une vue de dessous du collier du dispositif de la figure 1,
- la figure 3 est une coupe suivant A-A de la figure 2,
- la figure 4 est une vue en perspective d'un mode de réalisation modifié du dispositif de raccordement.The invention is shown by way of non-limiting example in the accompanying drawings in which
FIG. 1 is a partially cut axial view of the device according to the invention,
FIG. 2 is a bottom view of the collar of the device in FIG. 1,
FIG. 3 is a section along AA in FIG. 2,
- Figure 4 is a perspective view of a modified embodiment of the connection device.

Le dispositif conforme à l'invention a pour but de permettre un raccordement amovible rapide de deux canalisations, suivant lequel le dispositif de raccordement est positionné axialement et longitudinalement par rapport au plan de jointoiement des deux canalisations à raccorder. The device according to the invention aims to allow a quick removable connection of two pipes, according to which the connection device is positioned axially and longitudinally relative to the plane of jointing of the two pipes to be connected.

Le dispositif se compose d'un collier 1 comprenant deux demi-colliers li, 12, qui sont montés articulés l'un sur l'autre par une de leurs extrémités sur une pièce de support 2 comportant des axes d'articulation 3 pour ces demi-colliers. The device consists of a collar 1 comprising two half-collars li, 12, which are mounted articulated one on the other by one of their ends on a support part 2 comprising hinge pins 3 for these half - necklaces.

L'autre extrémité de ces demi-colliers est pourvue d'un moyen de serrage constitué, par exemple, par une vis 4 placée dans les fourches 5 prévues à chacune des autres extrémités des deux demi-colliers li, 12. The other end of these half-collars is provided with a clamping means constituted, for example, by a screw 4 placed in the forks 5 provided at each of the other ends of the two half-collars li, 12.

Le dispositif de support 2 commun aux deux demi-colliers 1 est lui-même supporté, de préférence de manière pivotante, par une portion d'axe 6 fixée par un prolongement coudé 61 à l'une des canalisations 7 à l'extrémité de laquelle doit être raccordée de manière étanche l'autre canalisation 8. The support device 2 common to the two half-collars 1 is itself supported, preferably in a pivoting manner, by a portion of axis 6 fixed by an elbow extension 61 to one of the pipes 7 at the end of which must be tightly connected to the other pipe 8.

Les canalisations 7 et 8 sont pourvues, à hauteur de leur plan de jointoiement 9, de collerettes externes 71 et Si qui viennent se loger dans des rainures circulaires 10 formées dans les deux demicolliers 11, 12. The pipes 7 and 8 are provided, at the height of their jointing plane 9, with external flanges 71 and Si which are housed in circular grooves 10 formed in the two semi-collars 11, 12.

Le prolongement 61 est fixé à la canalisation 7 de façon que le collier 1 ait son axe qui soit coaxial avec celui de la canalisation 7 tandis que son plan médian, c'est-à-dire le plan de la rainure 10, est confondu avec le plan de jointoiement 9 des deux canalisations 7 et 8 à raccorder. The extension 61 is fixed to the pipe 7 so that the collar 1 has its axis which is coaxial with that of the pipe 7 while its median plane, that is to say the plane of the groove 10, is coincident with the jointing plane 9 of the two pipes 7 and 8 to be connected.

La canalisation 7 pourra être constituée par un manchon rigide venant s'assembler de manière amovible ou non, par exemple par une collerette 72, à l'extrémité de la canalisation de l'installation fixe devant être raccordée. The pipe 7 may be constituted by a rigid sleeve coming to be assembled removably or not, for example by a flange 72, at the end of the pipe of the fixed installation to be connected.

Un ressort 10 non représenté sur les figures 1 et 2, est prévu autour du support 2 ou de son axe 6 afin de tendre constamment à rapprocher les deux demicolliers 11 et 12 de part et d'autre de la collerette 7 .  A spring 10, not shown in FIGS. 1 and 2, is provided around the support 2 or its axis 6 in order to constantly tend to bring the two semi-collars 11 and 12 closer to each other on the flange 7.

Dans ce cas, la partie médiane de ce ressort est enroulée autour du support 2 afin de se loger dans une rainure 21 tandis que les deux branches viennent s'appuyer élastiquement contre les deux demi-colliers li et 12.  In this case, the middle part of this spring is wound around the support 2 in order to be housed in a groove 21 while the two branches come to bear elastically against the two half-collars li and 12.

Egalement, chacun des demi-colliers 11 et 12 est pourvu d'une surface inclinée 11, cette surface inclinée étant prévue sur la face latérale 111 du collier qui est située à l'oppose de la canalisation 7 qui les supporte par l'axe 6 et son prolongement 6 . L'inclinaison de cette surface est dirigée vers l'intérieur de cette canalisation de façon que lorsque la vis 4 est partiellement desserrée, il soit possible de mettre en place ou de retirer la canalisation 8 du dispositif de raccordement, en exerçant une poussée ou une traction axiale sur cette canalisation 8 afin d'écarter l'un de l'autre les demi-colliers 11, 12 à l'encontre du ressort 10. Also, each of the half-collars 11 and 12 is provided with an inclined surface 11, this inclined surface being provided on the lateral face 111 of the collar which is located opposite the pipe 7 which supports them by the axis 6 and its extension 6. The inclination of this surface is directed towards the interior of this pipe so that when the screw 4 is partially loosened, it is possible to install or remove the pipe 8 from the connection device, by exerting a push or a axial traction on this pipe 8 in order to separate the half-collars 11, 12 from each other against the spring 10.

On remarque que lors de cette manipulation, le joint d'étanchéité placé entre les deux collerettes reste prisonnier des deux demi-colliers afin de rester en place lors d'un nouveau raccordement. Note that during this manipulation, the seal placed between the two flanges remains trapped in the two half-collars in order to remain in place during a new connection.

Suivant la figure 4, on a représenté en perspective un mode de réalisation légèrement modifié du dispositif de raccordement et, dans ce cas, les deux demi-colliers 11, 12 sont montés directement à pivotement sur l'axe 6 dont le prolongement 61 est fixé à l'une des canalisations à raccorder (non représentée). According to Figure 4, there is shown in perspective a slightly modified embodiment of the connection device and, in this case, the two half-collars 11, 12 are mounted directly to pivot on the axis 6 whose extension 61 is fixed to one of the pipes to be connected (not shown).

Dans ce cas également, le ressort 10 est enroulé autour de l'axe 6 et la vis 4 pourvue d'un écrou à oreille 41, est montée à pivotement par un axe 42 dans la fourche d'extrémité de l'un des demicolliers 11, 12.  In this case also, the spring 10 is wound around the axis 6 and the screw 4 provided with a wing nut 41, is pivotally mounted by an axis 42 in the end fork of one of the half-clamps 11 , 12.
