The female end-piece comprises two successive annular surfaces, the diameter of a first annular surface 7 being greater than the external diameter of the ribs 4 of the male end-piece 3, and the diameter of a second internal annular surface 8 being equal to that of the outer wall of the male end-piece.

Description

"Raccord pour tuyau"
La présente invention concerne un raccord pour tuyau, comportant un embout femelle et un embout mâle s'insérant dans l'embout femelle, la surface extérieure de l'embout mâle étant garnie de rainures périphériques, un anneau d'étanchéité bloqué dans la direction axiale du raccord au moyen de parois substantiellement étant prévu entre l'embout mâle et l'embout femelle, et la face interne de l'embout femelle comportant deux surfaces annulaires axiales derrière l'anneau d'étancheité, vu dans la direction d'insertion de l'embout mâle."Hose connection"
The present invention relates to a hose connector, comprising a female end piece and a male end fitting inserted into the female end piece, the external surface of the male end piece being provided with peripheral grooves, a sealing ring locked in the axial direction. of the connection by means of walls substantially being provided between the male end piece and the female end piece, and the internal face of the female end piece comprising two axial annular surfaces behind the sealing ring, seen in the direction of insertion of the male end.

On connaît du document DE-A-2 150 831 un raccord pour tuyaux à surface extérieure lisse, dans lequel la face interne de l'embout femelle comporte deux surfaces annulaires de diamètres différents et permettant de monter l'embout mâle et l'embout femelle de manière à ce qu'ils forment un angle l'un par rapport à l'autre, Des raccords de ce type peuvent partiellement suppléer à l'utilisation de pièces d'angle aux endroits où le tuyau est coudé. Document DE-A-2 150 831 discloses a fitting for pipes with a smooth external surface, in which the internal face of the female end piece has two annular surfaces of different diameters and which makes it possible to mount the male end piece and the female end piece. so that they form an angle to each other. Fittings of this type can partially compensate for the use of corner pieces at the places where the pipe is bent.

On connaît par ailleurs des raccords pour tuyaux dans lesquels la surface extérieure de l'embout mâle est pourvue de nervures périphériques. Dans ce cas, le joint d'étanchéité est normalement positionné de telle sorte qu'il soit supporté par l'embout mâle entre les deux nervures les plus proches de l'extrémité libre de l'embout mâle. L'extrémité libre de l'embout mâle est alors ordinairement appliquée contre le fond de l'embout femelle. Pipe fittings are also known in which the outer surface of the male end piece is provided with peripheral ribs. In this case, the seal is normally positioned so that it is supported by the male end piece between the two ribs closest to the free end of the male end piece. The free end of the male end piece is then usually applied against the bottom of the female end piece.

Comme la surface acérée de cette extrémité libre est souvent inclinée, le bord de l'embout mâle n'est pas ordinairement en appui en tous points contre le fond de l'embout femelle, mais des espaces apparaissent entre ltextré- mité de l'embout mâle et l'embout femelle, ces ouvertures entraînant une accumulation aisée de saletés Des éclats ou analogue, peuvent aisément s'introduire dans ces espaces, car les bords acérés de l'embout mâle sont souvent aigüs et rugueux. Il est à noter par ailleurs que, en fonction du point de coupe de l'embout mâle, il peut se former une cavité entre le fond de l'embout femelle et la face extrême de l'embout mâle, et que de la saleté peut pénétrer dans cette cavité à travers lesdits espaces.As the sharp surface of this free end is often inclined, the edge of the male end piece is not usually supported in all points against the bottom of the female end piece, but spaces appear between the end of the end piece. male and female end, these openings causing an easy accumulation of dirt Shards or the like, can easily be introduced into these spaces, because the sharp edges of the male end are often sharp and rough. It should also be noted that, depending on the cutting point of the male end piece, a cavity can form between the bottom of the female end piece and the end face of the male end piece, and that dirt can penetrate this cavity through said spaces.

L'invention a pour objet un raccord pour tuyau qui permet de garantir qu'il ne se forme pas de cavités ou d'espaces accumulateurs de saletés dans le raccord lorsque les embouts mâle et femelle sont mis bout à bout. The subject of the invention is a connector for a pipe which makes it possible to guarantee that no cavities or spaces accumulating dirt in the connector are formed when the male and female ends are placed end to end.

Le raccord selon l'invention est caractérisé en ce que le diamètre de la première surface annulaire, qui est la plus proche de l'anneau d'étanchéité, correspond substantiellement au plus grand diamètre des nervures de l'embout mâle et en ce que le diamètre de la seconde surface annulaire qui est située après la première correspond substantiellement au diamètre extérieur de la paroi de l'embout mâle.The connector according to the invention is characterized in that the diameter of the first annular surface, which is closest to the sealing ring, corresponds substantially to the largest diameter of the ribs of the male end piece and in that the the diameter of the second annular surface which is located after the first corresponds substantially to the outside diameter of the wall of the male end piece.

En raison de la structure de l'embout femelle, il ne se forme au moins pas de profonds creux ou trous entre l'embout femelle et l'embout mâle car l'embout mâle est toujours pressé contre l'embout femelle lorsque ces deux embouts sont coaxiaux. L'embout femelle permet aussi au tube d'être positionné de manière inclinée par rapport à l'embout femelle si les nervures de l'embout mâle stéten- dent seulement sur une portion de la longueur du tuyau, ou si les rainures de l'embout mâle qui sont destinées à être positionnées près de l'orifice de l'embout femelle sont réalisées moins hautes. Due to the structure of the female end piece, at least no deep recesses or holes are formed between the female end piece and the male end piece since the male end piece is always pressed against the female end piece when these two end pieces are coaxial. The female end also allows the tube to be positioned at an angle to the female end if the ribs of the male end only extend over a portion of the length of the pipe, or if the grooves of the male end caps which are intended to be positioned near the orifice of the female end cap are made less high.

Afin de réaliser la meilleure étanchéité possible entre l'embout femelle et l'embout mâle, l'embout mâle est de préférence sans nervures sur une certaine distance à partir de son extrémité libre, cette distance correspondant substantiellement à la longueur de la seconde surface annulaire de l'embout femelle dans la direction axiale du joint. L'extrémité libre de l'embout mâle est par suite pressée contre la seconde surface annulaire de l'embout femelle et la toute dernière nervure est pressée contre le fond de la première zone de l'embout femelle, de sorte qu'il n'existe aucun creux entre l'embout femelle et l'embout mâle.  In order to achieve the best possible seal between the female end piece and the male end piece, the male end piece is preferably without ribs over a certain distance from its free end, this distance corresponding substantially to the length of the second annular surface. of the female end-piece in the axial direction of the joint. The free end of the male end piece is therefore pressed against the second annular surface of the female end piece and the very last rib is pressed against the bottom of the first region of the female end piece, so that it does not there is no gap between the female end and the male end.

Le raccord selon l'invention sera maintenant décrit plus en détails, en référence aux dessins annexés dans lesquels
Figure 1 est une vue en coupe longitudinale d'un raccord conforme à l'invention, et
Figure 2 montre le raccord selon lainvention, avec l'embout femelle et l'embout mâle formant un angle l'un par rapport à l'autre.The connector according to the invention will now be described in more detail, with reference to the accompanying drawings in which
FIG. 1 is a view in longitudinal section of a connector according to the invention, and
Figure 2 shows the connector according to the invention, with the female end and the male end forming an angle with respect to each other.

La figure 1 montre un embout femelle 2 solidaire d'un tuyau 1 en matière plastique et un embout mâle 3 qui est inséré dans l'embout femelle 2, le diamètre intérieur de cet embout mâle correspondant substantiellement à celui du tuyau 1. La surface extérieure de l'embout mâle est pourvue de nervures périphériques 4. L'espace entre les deux nervures d'extrémité est utilisé comme gorge d'étanchéité 5, dans laquelle est placé un anneau d'étanchéité 6, par exemple en caoutchouc. FIG. 1 shows a female end piece 2 secured to a plastic pipe 1 and a male end piece 3 which is inserted into the female end piece 2, the inside diameter of this male end piece substantially corresponding to that of the pipe 1. The external surface of the male endpiece is provided with peripheral ribs 4. The space between the two end ribs is used as a sealing groove 5, in which is placed a sealing ring 6, for example made of rubber.

La face interne de l'embout femelle entre la gorge 5 et le tuyau 1 forme deux surfaces axiales annulaires successives : une première surface annulaire 7 et une seconde surface annulaire 8. Ces deux surfaces sont séparées par un épaulement 9. The internal face of the female end piece between the groove 5 and the pipe 1 forms two successive annular axial surfaces: a first annular surface 7 and a second annular surface 8. These two surfaces are separated by a shoulder 9.

Conformément à l'invention, le diamètre de la première surface annulaire 7 correspond substantiellement au plus grand diamètre des nervures 4, ou il l'excède légèrement, tandis que le diamètre de la seconde surface annulaire 8 est égal au diamètre extérieur de l'embout mâle. Une partie 10 de l'extrémité libre de l'embout mâle n'a aucune nervure, et sa longueur dans le sens axial correspond substantiellement à la longueur de la seconde surface annulaire dans la même direction. According to the invention, the diameter of the first annular surface 7 corresponds substantially to the largest diameter of the ribs 4, or it slightly exceeds it, while the diameter of the second annular surface 8 is equal to the outside diameter of the end piece male. A part 10 of the free end of the male end piece has no ribs, and its length in the axial direction corresponds substantially to the length of the second annular surface in the same direction.

Il ressort des figures que la partie 10 de l'embout mâle remplit parfaitement l'évidement formé par la surface annulaire 8, tandis que la nervure 4 extrême vient en contact avec L'épaulement 9 et la première surface annulaire 7. En conséquence, l'extrémité libre de l'embout mâle est pressée hermétiquement contre l'embout femelle sur une relativement longue distance, et la vaste cavité située entre l embout femelle et l'embout mâle à proximité immédiate du point de connexion forme la gorge d'étanchéité 5. L'espace interne du tuyau 1 est donc prolongé par l'des pace interne de l'embout mâle 3 avec une différence diffi cillement appréciable, du fait que le diamètre de la seconde surface annulaire 8 correspond au diamètre extérieur de la partie 10. It appears from the figures that the part 10 of the male end piece perfectly fills the recess formed by the annular surface 8, while the end rib 4 comes into contact with the shoulder 9 and the first annular surface 7. Consequently, the the free end of the male end piece is pressed hermetically against the female end piece over a relatively long distance, and the large cavity located between the female end piece and the male end piece in the immediate vicinity of the connection point forms the sealing groove 5 The internal space of the pipe 1 is therefore extended by the internal space of the male end piece 3 with a difference which is appreciably appreciable, owing to the fact that the diameter of the second annular surface 8 corresponds to the external diameter of the part 10.

On peut voir sur la figure 2 que l'embout mâle et l'embout femelle peuvent, si on le désire, former un angle l'un par rapport à l-'autre,les nervures qui doivent être positionnées près de l'orifice de l'embout étant moins hautes que les autres nervures. Dans ce cas également, il est possible d'empêcher la formation de creux ou de trous entre l'embout mâle et l'embout femelle. It can be seen in Figure 2 that the male end and the female end can, if desired, form an angle with respect to each other, the ribs which must be positioned near the orifice of the end piece being less tall than the other ribs. In this case also, it is possible to prevent the formation of hollows or holes between the male end piece and the female end piece.

En variante, la seconde surface annulaire peut être formée par les surfaces de parties surélevées mutuellement espacées, de sorte que la première surface annulaire s'étend audelà de la seconde surface annulaire, et la face extérieure de l'embout femelle ne comporte qu'un seul épaulement, ce qui peut être avantageux en ce qui concerne l'aspect extérieur. La partie 10 de l'embout femelle peut aussi être plus courte que la surface annulaire 8, ce qui cependant affecte le caractère lisse de la surface de 1 'espace d'écoulement.  Alternatively, the second annular surface may be formed by the surfaces of mutually spaced raised portions, so that the first annular surface extends beyond the second annular surface, and the outer face of the female end piece has only one single shoulder, which may be advantageous as regards the external appearance. The part 10 of the female end piece can also be shorter than the annular surface 8, which however affects the smoothness of the surface of the flow space.
