An independent claim is also included for an assembly formed with an elastic clamping collar.

Description

L'invention concerne un outil de montage et de démontage d'un collier élastique de serrage sur un organe tubulaire, le collier refermé en boucle comportant deux extrémités, adaptées pour venir en prise mutuelle, l'outil étant du type décrit dans le préambule de la revendication 1.The invention relates to a tool for mounting and dismounting an elastic clamping collar on a tubular member, the collar closed loop having two ends, adapted to engage mutual engagement, the tool being of the type described in the preamble of claim 1.

Un tel outil est connu du document EP-A1-0 224 317 .Such a tool is known from the document EP-A1-0 224 317 .

Il est connu, d'une part, du document EP-A1-0 224 317 d'assurer la pose et la dépose d'un collier élastique avec un outil de type tenaille comportant un premier mors et un deuxième mors articulés sur un pivot.It is known, on the one hand, of the document EP-A1-0 224 317 to ensure the installation and removal of an elastic collar with a pincer type tool comprising a first jaw and a second jaw articulated on a pivot.

Le collier élastique en question est refermé en boucle et comprend deux extrémités dont l'une comporte une saillie radiale et l'autre un crochet apte à se verrouiller sur la saillie radiale de manière à refermer le collier élastique autour d'un organe tubulaire de type tuyau souple. Le premier et le deuxième mors de l'outil portent des profils différents qui coopèrent avec l'une ou l'autre des extrémités du collier. L'outil permet, par retournement, d'inverser la prise des mors par rapport aux extrémités respectives du collier, permettant ainsi de verrouiller ou déverrouiller les extrémités du collier afin de monter ou de démonter l'organe tubulaire.The elastic collar in question is closed loop and comprises two ends, one of which has a radial projection and the other a hook adapted to lock on the radial projection so as to close the elastic collar around a tubular member of the type flexible pipe. The first and second jaws of the tool have different profiles that cooperate with one or other end of the collar. The tool allows, by inversion, to invert the grip of the jaws relative to the respective ends of the collar, thereby locking or unlocking the ends of the collar to assemble or disassemble the tubular member.

Toutefois, cet outil est difficilement manipulable pour un montage ou un démontage du collier dans des endroits difficiles d'accès.However, this tool is difficult to manipulate for assembly or disassembly of the collar in hard to reach places.

Il est connu, d'autre part, une pince CAILLAU référencée 0260 comportant deux mors à fermeture parallèle, sur chacun desquels un embout orientable interchangeable permet de manipuler les colliers élastiques dans des endroits difficiles d'accès.It is known, on the other hand, a clamp CAILLAU referenced 0260 having two jaws parallel closure, on each of which an interchangeable swivel tip allows to manipulate the elastic collars in hard to reach places.

Cependant, l'orientation des embouts interchangeables est réalisée, de manière indépendante, avec un système vis-écrou sur chacun des mors de la pince. Ceci rend complexe les manipulations pour orienter précisément les embouts en regard l'un par rapport à l'autre.However, the orientation of the interchangeable tips is carried out independently with a screw-nut system on each of the jaws of the clamp. This makes handling complex to precisely orient the end pieces facing one another.

Un but de l'invention est de concevoir un outil simple de montage et/ou de démontage d'un collier élastique de serrage, tout en permettant de manipuler facilement les colliers élastiques dans les endroits difficiles d'accès.An object of the invention is to design a simple tool for mounting and / or disassembling an elastic clamping collar, while allowing easy handling elastic collars in hard to reach places.

Pour cela, l'invention a pour objet un outil, de montage et de démontage d'un collier élastique du type précité selon la revendication 1.For this purpose, the subject of the invention is a tool for mounting and dismounting an elastic collar of the aforementioned type according to claim 1.

D'autres caractéristiques sont décrites dans les revendications 2 à 8.Other features are described in claims 2 to 8.

L'invention a également pour objet un ensemble formé d'au moins un collier élastique de serrage, refermé en boucle, de forme générale circulaire, comportant deux extrémités dont l'une comprend une saillie radiale de verrouillage s'étendant en projection externe et dont l'autre extrémité comprend un crochet de verrouillage coopérant avec la saillie radiale pour solidariser élastiquement et de manière réversible les deux extrémités du collier l'une sur l'autre ; et d'un outil tel que décrit ci-dessus.The subject of the invention is also an assembly formed of at least one clamping collet, closed in a loop, of generally circular shape, comprising two ends, one of which comprises a radial protrusion of locking extending in external projection and of which the other end comprises a locking hook cooperating with the radial projection to elastically and reversibly fasten the two ends of the collar one on the other; and a tool as described above.

Selon une autre caractéristique, l'extrémité du collier élastique comportant la saillie radiale comprend, en outre, du côté de cette saillie opposé à l'extrémité associée du collier, un bossage s'étendant radialement extérieurement, et en ce que l'encoche de guidage et/ou de centrage de chaque profil de prise du deuxième mors coopère avec le bossage en phase de démontage du collier.According to another characteristic, the end of the elastic collar comprising the radial projection further comprises, on the side of this projection opposite to the associated end of the collar, a boss extending radially outwards, and in that the notch of guiding and / or centering each gripping profile of the second jaw cooperates with the boss in disassembly phase of the collar.

L'invention va maintenant être décrite, sans caractère limitatif, en se référant aux Figures annexées, dans lesquelles :

  • la Figure 1 est une vue de face de l'outil selon l'invention représentant une première orientation générale de prise du collier par rapport aux mors de l'outil ;

Sur la Figure 1, un outil 10 suivant l'invention est représenté en prise avec un collier élastique de serrage 12, ce collier étant destiné au serrage sur un organe tubulaire tel qu'un tuyau souple disposé dans un compartiment moteur d'un véhicule automobile. L'outil 10 comprend une première branche 14 et une deuxième branche 16 reliées par une articulation en ciseau par un pivot 18. La première branche 14 comprend une première poignée 20 et un premier mors 22 disposés de part et d'autre de l'articulation à pivot 18. De même, la deuxième branche 16 comporte une deuxième poignée 24 et un deuxième mors 26 disposés de part et d'autre de l'articulation en pivot 18.On the Figure 1 , a tool 10 according to the invention is shown engaged with an elastic clamping collar 12, this collar being intended for clamping on a tubular member such as a flexible pipe arranged in a motor compartment of a motor vehicle. The tool 10 comprises a first branch 14 and a second branch 16 connected by a chisel joint by a pivot 18. The first branch 14 comprises a first handle 20 and a first jaw 22 arranged on either side of the articulation Similarly, the second branch 16 comprises a second handle 24 and a second jaw 26 disposed on either side of the pivot joint 18.

Dans l'exemple représenté, l'outil 10 s'étend suivant un plan général représenté par le plan de la Figure 1. Le collier 12 est refermé en boucle de forme générale circulaire, et est disposé dans un plan général sensiblement parallèle au plan général de l'outil 10. Le premier mors 22 et le deuxième mors 26 sont configurés de telle manière qu'un rapprochement mutuel des poignées 20 et 24 tend à rapprocher les mors 22 et 26 l'un de l'autre.In the example shown, the tool 10 extends in a general plane represented by the plane of the Figure 1 . The collar 12 is closed in a loop of generally circular shape, and is arranged in a general plane substantially parallel to the general plane of the tool 10. The first jaw 22 and the second jaw 26 are configured in such a way that a mutual approximation of the handles 20 and 24 tend to bring the jaws 22 and 26 closer to each other.

Comme on le voit sur les Figures 10 et 11, le premier mors 22 présente une forme générale en U. Il comprend deux tronçons 28 et 30, sensiblement parallèles entre eux et parallèles au plan général de l'outil 10, reliés par un tronçon intermédiaire 32 sensiblement perpendiculaire aux tronçon 28 et 30.As we see on the Figures 10 and 11 , the first jaw 22 has a generally U-shaped shape. It comprises two sections 28 and 30, substantially parallel to each other and parallel to the general plane of the tool 10, connected by an intermediate section 32 substantially perpendicular to the sections 28 and 30.

Le deuxième mors 26 présente une forme générale en U semblable à celle du premier mors 26. Il comprend également deux tronçons 34 et 36, sensiblement parallèles entre eux et parallèles au plan général de l'outil 10, reliés par un tronçon intermédiaire 38 sensiblement perpendiculaire aux tronçons 34 et 36.The second jaw 26 has a generally U-shaped similar to that of the first jaw 26. It also comprises two sections 34 and 36, substantially parallel to each other and parallel to the general plane of the tool 10, connected by a substantially perpendicular intermediate section 38 to sections 34 and 36.

Les premier et deuxième mors 22 et 26 sont réalisés, de préférence, en tôle épaisse.The first and second jaws 22 and 26 are preferably made of thick sheet metal.

Le premier mors 22 comprend un chanfrein 40 intérieur disposé tout le long de la forme en U et en regard du deuxième mors 26. Le chanfrein 40 est incliné dans l'épaisseur de la tôle formant le premier mors 22, de telle manière que, vue en section transversale (Figure 11), la face 42 intérieure soit de hauteur inférieure à la face 44 extérieure de la forme en U du premier mors 22.The first jaw 22 comprises an inner chamfer 40 arranged all along the U-shape and facing the second jaw 26. The chamfer 40 is inclined in the thickness of the sheet forming the first jaw 22, so that, seen in cross section ( Figure 11 ), the internal face 42 is of height less than the outer face 44 of the U-shape of the first jaw 22.

Une encoche 46, centrée sur chacun des tronçons 28, 30 et 32 du premier mors 22, présente une face de base 48 entourée de deux faces latérales 50.A notch 46, centered on each of the sections 28, 30 and 32 of the first jaw 22, has a base face 48 surrounded by two lateral faces 50.

La face 48 de chaque encoche 46 est orientée de telle manière qu'elle forme un angle aigu avec la face intérieure 42 du premier mors 22. Le chanfrein 40 est orienté de telle manière qu'il forme un angle aigu avec la face extérieure 44 du premier mors 22 (Figure 5 à Figure 9).The face 48 of each notch 46 is oriented such that it forms an acute angle with the inner face 42 of the first jaw 22. The chamfer 40 is oriented such that it forms an acute angle with the outer face 44 of the first jaw 22 ( Figure 5 to Figure 9 ).

Le deuxième mors 26 présente sur la périphérie intérieure du U un évidement 52 continu à section en quart de cercle. Cet évidement forme la face interne d'un bec 54 effilé orienté vers le mors 22.The second jaw 26 has on the inner periphery of the U a continuous recess 52 quadrant section. This recess forms the inner face of a tapered nose 54 oriented towards the jaw 22.

Le même outil 10, comportant des mors en forme de U, comprend trois paires de profils de prise venus de matière avec les mors, à savoir une paire sur chaque tronçon du U. Chaque paire présente un profil chanfreiné 40 pourvu d'une encoche 46 disposée sur le premier mors 22, et un profil évidé 52 à bec effilé 54 sur le deuxième mors 26.The same tool 10, comprising U-shaped jaws, comprises three pairs of grip profiles integrally formed with the jaws, namely a pair on each section of the U. Each pair has a chamfered profile 40 provided with a notch 46. disposed on the first jaw 22, and a recessed profile 52 with tapered beak 54 on the second jaw 26.

Ainsi, comme représenté aux Figures 2 à 4, un collier élastique 12 de serrage vient en prise avec les mors de l'outil 10 selon trois orientations générales différentes prédéterminées.Thus, as represented in Figures 2 to 4 , an elastic clamping collar 12 engages with the jaws of the tool 10 according to three different predetermined general orientations.

En effet, les tronçons intermédiaires 32 et 38 des formes en U du premier 22 et du deuxième 26 mors permettent une orientation du collier 12 sensiblement parallèlement au plan général de l'outil 10. Les tronçons 30 et 36 disposés en extrémité libre des formes en U du premier 22 et du deuxième 26 mors permettent une deuxième orientation générale de prise du collier 12 sensiblement perpendiculairement au plan général de l'outil 10. Les tronçons 28 et 34 des formes en U du premier 22 et du deuxième 26 mors disposés à proximité de l'articulation en pivot 18 permettent une troisième orientation générale de prise du collier 12 sensiblement perpendiculairement au plan général de l'outil 10 et orientée à l'opposé de la deuxième orientation générale de prise du collier 12.Indeed, the intermediate portions 32 and 38 of the U-shaped first 22 and second 26 jaws allow an orientation of the collar 12 substantially parallel to the general plane of the tool 10. The sections 30 and 36 disposed at the free end of the U-shaped first 22 and second 26 jaws allow a second general setting direction of the collar 12 substantially perpendicular to the general plane of the tool 10. The sections 28 and 34 of the U-shapes of the first 22 and second 26 jaws disposed near the pivot joint 18 allow a third general setting direction of the collar 12 substantially perpendicular to the general plane of the tool 10 and facing away from the second general setting direction of the collar 12.

Selon les Figures 5 à 9, le collier 12 est refermé en boucle. Il comporte, de manière connue, une première extrémité 60 en forme de crochet trapézoïdal qui se termine par un bec recourbé vers l'intérieur 61, et une deuxième extrémité 62 dans laquelle sont formés un bossage externe 64 et une saillie extérieure sensiblement radiale 66. Le bossage 64 est adjacent à la face de la saillie 66 opposée à l'extrémité 62 du collier.According to Figures 5 to 9 , the collar 12 is closed in a loop. It comprises, in known manner, a trapezoidal hook-shaped first end 60 which terminates in an inward bent nose 61, and a second end 62 in which an outer boss 64 and a substantially radial outer projection 66 are formed. The boss 64 is adjacent to the face of the projection 66 opposite the end 62 of the collar.

Pour effectuer le montage du collier 12 afin de fixer un organe tubulaire, par exemple un tuyau souple sur un élément de moteur de véhicule automobile, le collier 12, à l'état déverrouillé et ouvert, est placé sur l'organe tubulaire. Les mors 22 et 26 de l'outil 10 sont disposés à proximité du crochet 60 et du bossage 64, de telle manière que le chanfrein 40 du premier mors 22 se place en appui à l'arrière du crochet 60, et que le bec effilé 54 du deuxième mors 26 vient au contact du bossage 64. Dans cette configuration, la saillie radiale 66 est positionnée entre le crochet 60 et le bossage 64 du collier 12. Une action sur les branches 20 et 24 de l'outil 10 tendant à les rapprocher entraîne un mouvement des mors 22 et 26 l'un vers l'autre, comme indiqué par les flèches de la Figure 5. En continuant ce mouvement de rapprochement des becs 22 et 26, le crochet 60 franchit élastiquement la saillie radiale 66 comme représenté sur la Figure 6.To mount the collar 12 to fix a tubular member, for example a flexible pipe on a motor vehicle engine element, the collar 12, in the unlocked and open state, is placed on the tubular member. The jaws 22 and 26 of the tool 10 are arranged near the hook 60 and the boss 64, so that the chamfer 40 of the first jaw 22 is placed in abutment with the rear of the hook 60, and that the tapered nose 54 of the second jaw 26 comes into contact with the boss 64. In this configuration, the radial projection 66 is positioned between the hook 60 and the boss 64 of the collar 12. An action on the branches 20 and 24 of the tool 10 tends to bringing closer causes the jaws 22 and 26 to move towards each other, as indicated by the arrows of the Figure 5 . Continuing this movement of approaching the beaks 22 and 26, the hook 60 resiliently crosses the radial projection 66 as shown in FIG. Figure 6 .

Une action sur les branches 20 et 24 de l'outil 10 tendant à éloigner le premier bec 22 du deuxième bec 26 entraîne alors le verrouillage du crochet 60 sur la saillie radiale 66, le bec recourbé 61 du crochet 60 étant engagé en prise avec celle-ci. Le collier 12 se trouve à l'état verrouillé et fermé tel que présenté sur la Figure 7.An action on the branches 20 and 24 of the tool 10 tending to move the first spout 22 from the second spout 26 then causes the hook 60 to lock on the radial projection 66, the curved spout 61 of the hook 60 being engaged in engagement with that -this. The collar 12 is in the locked and closed state as shown on the Figure 7 .

Depuis cet état, pour ouvrir et démonter le collier 12 de l'organe tubulaire, l'outil 10 est retourné de manière à inverser la prise des mors 22 et 26 sur la partie arrière du crochet 60 et la partie arrière du bossage 64.From this state, to open and dismount the collar 12 of the tubular member, the tool 10 is inverted to reverse the grip of the jaws 22 and 26 on the rear portion of the hook 60 and the rear portion of the boss 64.

Un mouvement tendant à rapprocher les mors 22 et 26, comme indiqué par les flèches de la Figure 7, permet de présenter le bord chanfreiné 40 et la face 48 de l'encoche 46 du premier mors 22 en regard du bossage 64 du collier 12, et le bec effilé 54 du deuxième mors 26 en regard de la partie arrière du crochet 60.A movement tending to bring the jaws 22 and 26 closer together, as indicated by the arrows of the Figure 7 , makes it possible to present the chamfered edge 40 and the face 48 of the notch 46 of the first jaw 22 facing the boss 64 of the collar 12, and the tapered nose 54 of the second jaw 26 facing the rear part of the hook 60.

En poursuivant le mouvement tendant à rapprocher les mors 22 et 26 l'un vers l'autre, le bossage 64 se centre entre les parois latérales 50 de l'encoche 46, et le chanfrein 40 vient au contact de la saillie radiale 66 et du bec recourbé 61 du crochet 60, comme représenté à la Figure 8. Un mouvement supplémentaire de rapprochement des mors 22 et 26 entraîne le guidage du bec recourbé 61 selon la pente du chanfrein 40 vers la face intérieure 42, et désengage le bec recourbé 61 de la prise avec la saillie radiale 66.Continuing the movement tending to bring the jaws 22 and 26 towards one another, the boss 64 is centered between the lateral walls 50 of the notch 46, and the chamfer 40 comes into contact with the radial projection 66 and the curved beak 61 of hook 60, as shown in FIG. Figure 8 . An additional movement of the jaws 22 and 26 towards one another causes the curved nose 61 to guide along the slope of the chamfer 40 towards the inner face 42, and disengages the curved nose 61 from the engagement with the radial projection 66.

Un mouvement tendant à éloigner les mors 22 et 26 l'un de l'autre, comme indiqué par les flèches de la Figure 9, permet alors la désolidarisation de la première extrémité 60 et de la deuxième extrémité 62 du collier 12, et ainsi son ouverture.A movement tending to move the jaws 22 and 26 away from each other, as indicated by the arrows of the Figure 9 , then allows the disengagement of the first end 60 and the second end 62 of the collar 12, and thus its opening.

L'invention a été décrite avec des mors en forme de U. Cependant, selon une variante non représentée, une forme en L comportant un profil de prise agencé sur chaque aile du L permet deux orientations générales prédéterminées de prise d'un collier élastique. L'une des orientations est sensiblement parallèle au plan général de l'outil, l'autre est sensiblement perpendiculaire au plan général de l'outil.The invention has been described with U-shaped jaws. However, according to a variant not shown, an L-shaped having a gripping profile arranged on each wing of the L allows two predetermined general orientations for gripping an elastic collar. One of the orientations is substantially parallel to the general plane of the tool, the other is substantially perpendicular to the general plane of the tool.

L'invention a été décrite précédemment avec un outil de type pince comportant deux branches articulées comprenant chacune un mors et une poignée. Selon une variante non représentée, l'outil comporte un ensemble de mors articulés distant d'un ensemble de poignées articulées également, les deux ensembles étant reliés par un mécanisme d'actionnement à câble.The invention has been described above with a pliers-type tool comprising two articulated branches each comprising a jaw and a handle. According to a variant not shown, the tool comprises a set of articulated jaws remote from a set of articulated handles also, the two sets being connected by a cable actuating mechanism.

Grâce à l'invention, il est possible de manipuler un collier élastique de serrage dans des endroits difficiles d'accès avec un outil simple disposant de plusieurs orientations générales de prise du collier.Thanks to the invention, it is possible to manipulate an elastic clamping collar in hard to reach places with a simple tool having several general orientations for gripping the collar.
