Description

l 2918724 Dispositif de fixation et ensemble correspondantl 2918724 Fixing device and corresponding assembly

La présente invention concerne un dispositif de fixation d'un objet à une structure, du type muni d'un premier élément de liaison comportant un organe de fixation à la structure et d'un deuxième élément de liaison comportant un organe d'attache de l'objet. Elle s'applique notamment aux ensembles de fixation de tuyaux ou de faisceaux de câble dans des véhicules automobiles. On connaît des dispositifs de fixation du type indiqué ci-dessus adaptés pour fixer un objet allongé, tel qu'un tuyau, à une structure, par exemple à une structure d'un véhicule automobile. Ces dispositifs de fixation comprennent un organe d'attache aussi connu sous le nom collier Rilsan . Ces dispositifs comportent un élément de liaison devant être fixé à la structure et un élément de liaison comportant l'organe d'attache du tuyau. Les deux éléments de liaison sont venus de matière et liés rigidement l'un à l'autre. En conséquence, la position du collier par rapport à la structure dépend dans une large mesure de la position du premier élément de liaison, ce qui limite l'utilisation de ces colliers. L'invention a donc pour but d'augmenter la flexibilité d'utilisation de ces disposi- tifs de fixation. A cet effet, l'invention a pour objet un dispositif de fixation du type indiqué ci-dessus, caractérisé en ce que le premier élément de liaison comporte un premier organe de liaison et le deuxième élément de liaison comporte un deuxième organe de liaison, les deux organes de liaison coopérant par complémentarité de formes et reliant le premier et le deuxième éléments de liaison, et en ce que les deux organes de liaison ont un degré de liberté en rotation autour d'un premier axe de rotation. Selon des modes particuliers de réalisation de l'invention, le dispositif de fixation selon l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes : - les deux organes de liaison ont un degré de liberté en rotation selon un deuxième axe de rotation et un troisième axe de rotation perpendiculaires entre eux et par rapport au premier axe de rotation ; -les deux organes de liaison sont formés par un joint à rotule ayant une coupelle et une rotule ; 2 2918724 - le premier organe de liaison est la coupelle et le deuxième organe de liaison est la rotule ; le dispositif de fixation comporte des moyens de guidage du deuxième organe de liaison par rapport au premier organe de liaison, ces moyens de guidage limitant la 5 mobilité de ces deux organes de liaison entre eux à un seul degré de liberté en rotation lorsque les deux organes de liaison sont dans une plage de configurations déterminée ; - les deux éléments de liaison comportent des moyens de blocage des deux éléments de liaison dans une configuration déterminée, notamment par complémentarité de formes et en particulier par encliquetage ; 10 - chacun des premier et deuxième éléments de liaison est fabriqué en matière plastique, notamment d'un seul tenant ; et - l'organe d'attache est un collier formé d'une languette souple en forme de boucle, et muni de moyens de serrage adaptés pour s'opposer à une ouverture de la boucle, notamment un collier Rilsan .  The present invention relates to a device for fixing an object to a structure, of the type provided with a first connecting element comprising a fastener to the structure and a second connecting element comprising a fastening member of the 'object. It applies in particular to sets for fixing pipes or cable bundles in motor vehicles. Fastening devices of the type indicated above are known adapted for fixing an elongate object, such as a pipe, to a structure, for example to a structure of a motor vehicle. These fasteners include an attachment member also known as the Rilsan collar. These devices comprise a connecting element to be fixed to the structure and a connecting element comprising the pipe fastener. The two connecting elements are integral and rigidly connected to each other. As a result, the position of the collar relative to the structure depends to a large extent on the position of the first connecting element, which limits the use of these collars. The invention therefore aims to increase the flexibility of use of these fastening devices. For this purpose, the subject of the invention is a fixing device of the type indicated above, characterized in that the first connecting element comprises a first connecting element and the second connecting element comprises a second connecting element, the two connecting members cooperating by complementarity of shapes and connecting the first and second connecting elements, and in that the two connecting members have a degree of freedom in rotation about a first axis of rotation. According to particular embodiments of the invention, the fixing device according to the invention may comprise one or more of the following characteristics: the two connecting members have a degree of freedom in rotation along a second axis of rotation and a third axis of rotation perpendicular to each other and to the first axis of rotation; the two connecting members are formed by a ball joint having a cup and a ball joint; 2 2918724 - the first connecting member is the cup and the second connecting member is the ball joint; the fixing device comprises means for guiding the second connecting member relative to the first connecting member, these guiding means limiting the mobility of these two connecting members to each other at a single degree of freedom of rotation when the two members link are in a determined range of configurations; the two connecting elements comprise means for blocking the two connecting elements in a given configuration, in particular by complementarity of shapes and in particular by snap-fastening; Each of the first and second connecting elements is made of plastic material, in particular as a single piece; and - the fastener is a collar formed of a flexible tongue in the form of a loop, and provided with clamping means adapted to oppose an opening of the loop, in particular a Rilsan collar.

15 L'invention a également pour objet un ensemble, du type comprenant une structure de véhicule automobile - un tuyau ou un faisceau de câbles à fixer sur la structure de véhicule automo-bile - au moins un dispositif de fixation du tuyau ou faisceau de câbles sur la structure 20 de véhicule automobile, caractérisé en ce que le ou chaque dispositif de fixation est un dispositif tel que défini ci-dessus. Selon un mode de réalisation particulier, l'ensemble comporte une ouverture oblongue dans laquelle s'engage l'organe de fixation du premier élément de liaison avec un seul degré de liberté en translation.The subject of the invention is also an assembly, of the type comprising a motor vehicle structure - a pipe or a bundle of cables to be fixed on the automobile-bile vehicle structure - at least one device for fastening the pipe or cable bundle on the structure 20 of a motor vehicle, characterized in that the or each fixing device is a device as defined above. According to a particular embodiment, the assembly comprises an oblong opening in which engages the fixing member of the first connecting element with a single degree of freedom in translation.

5 Sur la Figure 1 est montré un ensemble qui est une partie d'un véhicule automobile, désigné par la référence générale 2. L'ensemble 2 comporte une structure de véhicule automobile 4, telle qu'une paroi en tôle. L'ensemble 2 comporte en outre un objet oblongue 6, tel qu'un tuyau ou un faisceau de câbles devant être fixé à la structure 4.In Figure 1 is shown an assembly which is a part of a motor vehicle, designated by the general reference 2. The assembly 2 comprises a motor vehicle structure 4, such as a sheet metal wall. The assembly 2 further comprises an oblong object 6, such as a pipe or a bundle of cables to be fixed to the structure 4.

10 L'ensemble 2 est en outre muni de trois dispositifs de fixation 8 fixant l'objet oblongue 6 à la structure du véhicule automobile 4. La structure de véhicule automobile 4 comporte des trous de fixation oblongue 10. L'un des dispositifs de fixation 8 est décrit plus en détail en se référant à la Fi- 15 gure 2, les autres dispositifs de fixation étant identiques. Le dispositif de fixation 8 comporte un premier élément de liaison 12 ainsi qu'un deuxième élément de liaison 14. Le premier élément de liaison 12 est muni d'un organe de fixation 16 adapté pour fixer le dispositif de fixation 8 à la structure 4, en coopérant avec le trou 10. En 20 l'occurrence, l'organe de fixation 16 est constitué par deux nez d'encliquetage 18. L'organe de fixation 16 et le trou oblongue 10 sont configurés de telle sorte que le premier élément de liaison 12 est libre en translation par rapport à la structure 4 dans le trou oblongue 10 selon une seule direction dans l'espace, mais est fixe dans les deux autres directions. Par ailleurs, l'élément de liaison 12 est fixe en rotation par rapport à la 25 structure 4. Le premier élément de liaison 12 est en outre muni d'une collerette d'étanchéité 20 dont le bord extérieur s'applique de manière étanche sur la surface de la structure 4. La collerette d'étanchéité 20 a une forme générale de tronc de cône s'évasant vers l'organe de fixation 16. En outre, la collerette d'étanchéité 20 est adaptée pour rattraper 30 les jeux de montage entre l'organe de fixation 16 et la structure 4. Le premier élément de liaison 12 est en outre muni d'un premier organe de liai-son 24, qui sera décrit plus en détail ci-après. Le deuxième élément de liaison 14 comporte une partie de liaison 26 et un organe d'attache 28 (voir Figure 4).The assembly 2 is further provided with three fasteners 8 fixing the oblong object 6 to the structure of the motor vehicle 4. The motor vehicle structure 4 has oblong fixing holes 10. One of the fastening devices 8 is described in more detail with reference to FIG. 2, the other fasteners being identical. The fixing device 8 comprises a first connecting element 12 as well as a second connecting element 14. The first connecting element 12 is provided with a fixing member 16 adapted to fix the fastening device 8 to the structure 4, cooperating with the hole 10. In this case, the fastening member 16 is constituted by two snap-fastening noses 18. The fastening member 16 and the oblong hole 10 are configured so that the first element of FIG. link 12 is free in translation relative to the structure 4 in the oblong hole 10 in a single direction in space, but is fixed in the other two directions. Furthermore, the connecting element 12 is fixed in rotation with respect to the structure 4. The first connecting element 12 is further provided with a sealing collar 20 whose outer edge is sealingly applied to the surface of the structure 4. The sealing flange 20 has a generally conical truncated shape flaring towards the fixing member 16. In addition, the sealing flange 20 is adapted to make up the mounting clearance. between the fixing member 16 and the structure 4. The first connecting element 12 is further provided with a first connecting member 24, which will be described in more detail below. The second connecting member 14 has a connecting portion 26 and a fastener 28 (see Figure 4).

4 2918724 La partie de liaison 26 est munie d'un deuxième élément de liaison 30 et d'une tige 32 reliant le deuxième élément de liaison 30 à l'organe d'attache 28. La tige 32 a une section sensiblement circulaire de diamètre D et s'étend selon un axe propre A-A. Les premier et second éléments de liaison 12 et 14 sont fabriqués dans une 5 même matière plastique, plus particulièrement du polyamide 6-6. Le premier organe de liaison 24 et le deuxième organe de liaison 30 forment un joint à rotule coopérant par complémentarité de formes et reliant le premier 12 et le deuxième 14 éléments de liaison. A cet effet, le premier organe de liaison 24 forme une coupelle recevant par complémentarité de formes le deuxième organe de liaison 30 qui 10 est formé par une rotule. Le joint à rotule confère une liberté de rotation du deuxième élément de liaison 14 par rapport au premier élément de liaison 12 autour de trois axes de rotation. Un premier axe de rotation X-X ainsi qu'un deuxième axe de rotation Y-Y s'étendent parallèlement à un plan défini par la structure 4. Ces deux axes de rotation X-X et Y-Y 15 s'étendent perpendiculairement l'un par rapport à l'autre. Le joint à rotules, formé par les organes de liaison 24 et 30, est également adapté pour permettre une rotation du premier élément de liaison 12 par rapport au deuxième élément de liaisonl4 autour d'un troisième axe de rotation Z-Z, qui s'étend perpendiculairement au premier axe de rotation X-X et au deuxième axe de rotation Y- 20 Y. Le dispositif de fixation 8 est en outre muni de moyens de guidage 36 du deuxième organe de liaison 30 par rapport au premier organe de liaison 24 lorsque ces deux organes de liaison 24, 30 sont dans une plage de configurations déterminée. Les moyens de guidage 36 définissent une configuration neutre à partir de la- 25 quelle le deuxième élément de liaison 14 peut être pivoté soit autour de l'axe X-X, soit autour de l'axe Y-Y. Dans le cas présent dans la configuration neutre, l'axe propre A-A de la tige 32 coïncide avec l'axe Z-Z. Cette configuration neutre est représentée sur la Figure 2. Ces moyens de guidage 36 comportent des fourchettes de guidage 38 disposées 30 sur le premier organe de liaison 24. Chacune des fourchettes de guidage 38 est adaptée pour coopérer avec la tige 32 du deuxième élément de liaison 14 et de guider celui-ci de telle sorte que, lorsque l'axe A-A de la tige 32 est décalé angulairement de l'axe Z-Z, un déplacement exclusif en rotation autour de l'un seul des axes X-X et Y-Y est possible, mais qu'une rotation autour de l'autre axe Y-Y ou X-X est empêchée.The connecting portion 26 is provided with a second connecting element 30 and a rod 32 connecting the second connecting element 30 to the fastening member 28. The rod 32 has a substantially circular section of diameter D and extends along a proper axis AA. The first and second connecting members 12 and 14 are made of the same plastic material, more particularly polyamide 6-6. The first connecting member 24 and the second connecting member 30 form a ball joint cooperating by complementarity of shapes and connecting the first 12 and the second 14 connecting elements. For this purpose, the first connecting member 24 forms a cup receiving formally complementing the second connecting member 30 which is formed by a ball joint. The ball joint provides a freedom of rotation of the second connecting element 14 relative to the first connecting element 12 around three axes of rotation. A first axis of rotation XX and a second axis of rotation YY extend parallel to a plane defined by the structure 4. These two axes of rotation XX and YY 15 extend perpendicularly relative to each other . The ball joint, formed by the connecting members 24 and 30, is also adapted to allow a rotation of the first connecting element 12 with respect to the second connecting element 14 around a third axis of rotation ZZ, which extends perpendicularly. at the first axis of rotation XX and the second axis of rotation Y-Y. The fastening device 8 is further provided with guiding means 36 of the second connecting member 30 with respect to the first connecting member 24 when these two members of FIG. link 24, 30 are in a determined range of configurations. The guiding means 36 define a neutral configuration from which the second connecting element 14 can be rotated either about the X-X axis or around the Y-Y axis. In the present case in the neutral configuration, the proper axis A-A of the rod 32 coincides with the axis Z-Z. This neutral configuration is shown in FIG. 2. These guide means 36 comprise guide forks 38 arranged on the first connecting member 24. Each of the guide forks 38 is adapted to cooperate with the rod 32 of the second connecting element 14 and guide it so that, when the axis AA of the rod 32 is angularly offset from the axis ZZ, an exclusive displacement in rotation around one of the axes XX and YY is possible, but that a rotation about the other axis YY or XX is prevented.

5 2918724 Le dispositif de fixation 8 est en outre muni de moyens de blocage 40 adaptés pour bloquer le deuxième élément de liaison 14 par rapport au premier élément de liai-son 12 dans des configurations prédéterminées. Dans le cas présent, les moyens de blocage 40 sont adaptés pour bloquer les deux éléments de liaison 12, 14 dans des 5 configurations dans lesquelles l'axe propre A-A de la tige 32 coïncide, soit avec le premier axe de rotation X-X, soit avec le deuxième axe de rotation Y-Y. Ces moyens de blocage 40 comportent, dans le cas présent, des organes d'encliquetage 42 disposés sur les fourchettes de guidage 38. Chaque fourchette 38 délimite un fond 44 qui est élargi et correspond sensiblement au diamètre extérieur D de la tige 32. Les organes 10 d'encliquetage 42 disposés sur les branches des fourchettes de guidage 38 ont une distance mutuelle qui est inférieure au diamètre D de la tige 32 afin de permettre un encliquetage élastique de la tige 32 dans le fond 44 (voir Figure 5). L'organe d'attache 28 est de préférence un collier formé d'une languette souple 60 en forme de boucle muni de moyens de serrage 62 adaptés pour s'opposer à une 15 ouverture de la boucle. Les moyens de serrage 62 sont, par exemple, des rainures ménagées dans la languette 60 coopérant avec un doigt de serrage 64. De préférence, l'organe d'attache 28 est un collier type Rilsan. Le dispositif de fixation est d'une part facile à fabriquer étant donné que chacun des deux éléments de liaison 12, 14 est fabriqué chaque fois d'une seule pièce en ma- 20 tière plastique. En outre, le premier élément de liaison 12 peut être fixé sur la structure 4 indépendamment du deuxième élément de liaison 14. De même, les deuxièmes éléments de liaison 14 sont fixables sur l'objet 6 indépendamment du premier élément de liaison 12.The fixing device 8 is further provided with locking means 40 adapted to lock the second connecting element 14 with respect to the first connecting element 12 in predetermined configurations. In this case, the locking means 40 are adapted to lock the two connecting elements 12, 14 in configurations in which the own axis AA of the rod 32 coincides, either with the first axis of rotation XX, or with the second axis of rotation YY. These locking means 40 comprise, in the present case, detent members 42 disposed on the guide forks 38. Each fork 38 defines a bottom 44 which is widened and substantially corresponds to the outside diameter D of the rod 32. The snap-fastener 42 on the legs of the guide forks 38 have a mutual distance which is smaller than the diameter D of the rod 32 to allow resilient snapping of the rod 32 in the bottom 44 (see Figure 5). The fastening member 28 is preferably a collar formed of a flexible tab 60 in the form of a loop provided with clamping means 62 adapted to oppose an opening of the loop. The clamping means 62 are, for example, grooves in the tongue 60 cooperating with a clamping finger 64. Preferably, the fastener 28 is a Rilsan type collar. The fixing device is easy to manufacture since each of the two connecting elements 12, 14 is manufactured in one piece of plastics material. In addition, the first connecting element 12 can be fixed on the structure 4 independently of the second connecting element 14. Similarly, the second connecting elements 14 are fixable on the object 6 independently of the first connecting element 12.

25 Une succession d'étapes d'assemblage est la suivante : a) fixation du premier élément de liaison 12 à la structure 4 ; b) fixation du deuxième élément de liaison 14 à l'objet à fixer 6 ; c) après les étapes a) et b), assemblage des deux organes de liaison 24, 30 en-semble ainsi fixant l'objet à fixer à la structure.A succession of assembly steps is as follows: a) attachment of the first connecting element 12 to the structure 4; b) fixing the second connecting element 14 to the object to be fixed 6; c) after the steps a) and b), assembly of the two connecting members 24, 30 together and fixing the object to be fixed to the structure.

30 Ainsi, l'assemblage est facile. Sur la Figure 6 est représenté un premier élément de liaison 12 selon une va-riante de l'invention. Ce premier élément de liaison 12 diffère de celui décrit précédemment par ce qui suit, les éléments analogues portant les mêmes références. Ce premier élément de liaison 12 comporte huit fourchettes de guidage 38 per- mettant, en plus de la rotation du deuxième élément de liaison 14 autour des deux axes b 2918724 de rotation X-X et Y-Y, la rotation autour de deux axes intermédiaires X'-X' et Y'-Y', s'étendant dans le même plan que les axes X-X et Y-Y et étant décalés de 45 par rapport aux axes X-X et Y-Y. 7Thus, the assembly is easy.
