Description

On connaît déjà notamment par le brevet français n° 78 16913 un collier de serrage constitué par une bande métallique enroulée sur elle-même, dont les deux brins portent des dents complémentaires sur leurs faces en regard et sont assemblés par une agrafe. Chaque brin présente d'autre part une butée et les deux butées sont susceptibles d'être saisies par un organe de préhension. L'une des deux butées du collier est cependant destinée à être arrachée au moment du serrage de celui-ci, lorsqu'il atteint une valeur convenable.We already know in particular from French patent n ° 78 16913 a clamp consisting of a metal band wound on itself, the two strands of which carry complementary teeth on their opposite faces and are assembled by a staple. Each strand has on the other hand a stop and the two stops are capable of being gripped by a gripping member. One of the two stops of the collar is however intended to be torn off when the latter is tightened, when it reaches a suitable value.

L'invention concerne un outil notamment un outil portatif pour la fixation d'un tel collier sur l'objet à serrer, tel par exemple qu'un tuyau en caoutchouc emmanché sur tube rigide en vue d'obtenir une grande cadence de mise en place du collier et d'assurer un serrage prédéterminé de celui-ci.The invention relates to a tool, in particular a portable tool for fixing such a collar to the object to be tightened, such as for example a rubber hose fitted on a rigid tube in order to obtain a high rate of installation. of the collar and to ensure a predetermined tightening thereof.

On connaît déjà des outils d'un type analogue. Ils comportent en général un corps à l'intérieur duquel coulisse un organe mobile sous l'action d'un moteur, par exemple un vérin pneumatique. Le corps et l'organe mobile présentent respectivement des surfaces destinées à prendre appui sur des butées prévues sur l'objet à fixer,lesdites butées étant rapprochées et/ou éloignées l'une de l'autre au moment de la fixation.Tools of a similar type are already known. They generally comprise a body inside which slides a movable member under the action of a motor, for example a pneumatic cylinder. The body and the movable member respectively have surfaces intended to bear on stops provided on the object to be fixed, said stops being brought closer and / or distant from each other at the time of fixing.

L'invention concerne donc un outil du genre qui vient d'être sommairement rappelé, spécialement adapté à la fixation des colliers de serrage, plus particulièrement des colliers du type décrit dans le brevet mentionné plus haut.The invention therefore relates to a tool of the kind which has just been summarily recalled, specially adapted for fixing the clamps, more particularly clamps of the type described in the patent mentioned above.

Selon l'invention, le corps de l'outil présente un sabot susceptible de prendre appui sur l'une des butées du collier cependant que son organe mobile comporte, à son extrémité active, un nez articulé dont un doigt et/ou un épaulement vient en contact avec la deuxième butée au cours du déplacement de l'organe mobile.According to the invention, the body of the tool has a shoe capable of bearing on one of the stops of the collar, while its movable member comprises, at its active end, an articulated nose of which a finger and / or a shoulder comes in contact with the second stop during the movement of the movable member.

Bien entendu la course théorique de l'organe mobile depuis sa position de repos jusqu'à sa position finale est au moins égale, et de préférence sensiblement supérieure,à la course nécessaire pour assurer un serrage convenable du collier et pour provoquer l'arrachement de la butée lorsque la tension de la bande dépasse une valeur prédéterminée.Of course the theoretical travel of the movable member from its rest position to its final position is at least equal, and preferably substantially greater, to the travel necessary to ensure proper tightening of the collar and to cause the tearing of the stop when the belt tension exceeds a predetermined value.

Grâce aux dispositions prévues par l'invention l'outil est de conception très simple, son poids ainsi que sa longueur restant assez faibles, ce qui en facilite l'utilisation pour des montages de colliers en série, notamment dans l'industrie automobile.Thanks to the arrangements provided by the invention, the tool is of very simple design, its weight and its length remaining fairly low, which facilitates its use for mounting collars in series, in particular in the automobile industry.

L'invention sera cependant mieux comprise et certaines caractéristiques secondaires ainsi que ses avantages apparaîtront au cours de la description qui va suivre d'un mode de réalisation avantageux, donné uniquement à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • - la figure 1 est une coupe longitudinale d'un outil conforme à l'invention,
  • - la figure 2 est une coupe suivant II-II de la figure 1.
The invention will however be better understood and certain secondary characteristics as well as its advantages will appear during the following description of an advantageous embodiment, given solely by way of example, with reference to the appended drawings in which:
  • FIG. 1 is a longitudinal section of a tool according to the invention,
  • - Figure 2 is a section along II-II of Figure 1.

Si l'on se reporte aux dessins on voit que l'outil présente une forme générale analogue à celle d'un pistolet dont le corps 1 comporte une crosse 2 destinéeà la manipulation. A l'intérieur du corps est monté coulissant un organe mobile 3 dont l'extrémité droite, considérée comme l'extrémité arrière, est attelée à un moteur non représenté. Ce moteur sera de préférence un vérin pneumatique logé à l'arrière du corps 1 et commandé par une gâchette 4 ou analogue disposée sur la crosse 2. Lorsque le moteur est commandé il provoque le déplacement de l'organe mobile 3 vers la droite de la figure, c'est-à-dire vers l'arrière de l'outil, le rappel de l'organe mobile dans la position de repos (représentée en trait plein sur la figure 1) étant assuré par tout moyen approprié, par exemple par un ressort incorporé au vérin.If we refer to the drawings we see that the tool has a general shape similar to that of a pistol whose body 1 has a stock 2 intended for handling. Inside the body is slidably mounted a movable member 3 whose straight end, considered as the rear end, is coupled to a motor not shown. This motor will preferably be a pneumatic cylinder housed at the rear of the body 1 and controlled by a trigger 4 or the like placed on the stock 2. When the motor is controlled, it causes the movable member 3 to move to the right of the figure, that is to say towards the rear of the tool, the return of the movable member to the rest position (shown in solid lines in FIG. 1) being ensured by any appropriate means, for example by a spring incorporated in the jack.

Le collier à serrer, désigné par la référence générale 5 est constitué essentiellement par une bande métallique enroulée sur elle-même, les deux brins 5a et 5b présentant des dents d'accrochage complémentaires sur leurs faces en regard. Une agrafe 6 enserre les deux brins 5a et 5b et évite ainsi que les dents ne soient accidentellement décrochées les unes des autres, après la mise en place du collier. Le brin 5a comporte une première butée 7 généralement obtenue par une déformation de la bande métallique, cependant que le brin 5b comporte une deuxième butée 8 d'un type analogue et décrite en détail dans le brevet précité. Ainsi qu'on le voit bien sur la figure 1, les deux butées 7 et 8 sont situées sur les faces extérieures des brins et du même côté par rapport à l'agrafe 6, la deuxième butée 8 étant de préférence très voisine de l'extrémité libre du brin 5b.The collar to be tightened, designated by the general reference 5, consists essentially of a metal strip wound on itself, the two strands 5a and 5b having complementary hooking teeth on their opposite faces. A clip 6 encloses the two strands 5a and 5b and thus prevents the teeth from being accidentally detached from each other, after the collar has been put in place. The strand 5a has a first stop 7 generally obtained by a deformation of the metal strip, while the strand 5b has a second stop 8 of a similar type and described in detail in the aforementioned patent. As can be seen in Figure 1, the two stops 7 and 8 are located on the outer faces of the strands and on the same side relative to the clip 6, the second stop 8 is preferably very close to the free end of the strand 5b.

A la partie inférieure 'du corps 1 et à l'avant de celui-ci est disposé un sabot la solidaire du corps. De préférence, ce sabot est amovible au moyen de vis 9. En effet, il peut être avantageux dans certains cas qu'un sabot déterminé soit adapté au diamètre du collier à serrer et comporte une surface courbe 1b sur laquelle le collier peut prendre appui. De toute façon ce sabot présente à l'avant une surface d'appui lc.pour la première butée 7 du collier.At the lower part 'of the body 1 and at the front thereof is disposed a shoe secured to the body. Preferably, this shoe is removable by means of screws 9. In fact, it may be advantageous in certain cases that a determined shoe is adapted to the diameter of the collar to be tightened and has a curved surface 1b on which the collar can bear. Anyway this shoe has at the front a support surface lc. For the first stop 7 of the collar.

L'extrémité avant de l'organe mobile 3 est constituée par un nez 10 articulé autour d'un axe 11 parallèle à l'axe du collier. Dans sa position de repos, représentée en trait plein sur la figure 1, le nez 10 se trouve engagé dans un logement 12 ménagé à l'extrémité avant du corps 1. La direction générale de ce logement est inclinée vers le haut et vers l'avant par rapport à l'axe longitudinal de l'organe mobile 3 pour des raisons qui apparaîtront plus loin.The front end of the movable member 3 is constituted by a nose 10 articulated around an axis 11 parallel to the axis of the collar. In its rest position, shown in solid lines in Figure 1, the nose 10 is engaged in a housing 12 formed at the front end of the body 1. The general direction of this housing is inclined upwards and towards the front relative to the longitudinal axis of the movable member 3 for reasons which will appear later.

De préférence, l'extrémité avant du corps comporte encore, au-dessous du logement 12, un petit sabot 13, amovible et interchangeable, dont la face inférieure 13a constitue un appui pour la face extérieure du brin 5b.Preferably, the front end of the body also comprises, below the housing 12, a small shoe 13, removable and interchangeable, the lower face 13a of which constitutes a support for the outer face of the strand 5b.

A sa partie inférieure le nez 10 présente un épaulement l0a,ou analogue, faisant saillie principalement de l'arrière vers l'avant de l'outil; son rôle apparaîtra plus loin.At its lower part, the nose 10 has a shoulder 10a, or the like, projecting mainly from the rear towards the front of the tool; its role will appear later.

Enfin, une rainure 14 est ménagée dans le corps de l'outil entre l'organe mobile 3 et le sabot la et s'étend vers l'arrière depuis l'extrémité avant du sabot la sur une longueur au moins égale à la course de l'organe mobile. Elle débouche dans un conduit 15 ouvert sur l'extérieur et éventuellement raccordé à un collecteur de déchets pour des raisons qui apparaîtront plus loin.Finally, a groove 14 is formed in the body of the tool between the movable member 3 and the shoe la and extends rearward from the front end of the shoe la over a length at least equal to the stroke of the mobile organ. It opens into a conduit 15 open to the outside and possibly connected to a waste collector for reasons which will appear later.

De préférence également, le nez 10 comporte en arrière de l'épaulement 10a un organe élastique escamotable situé à l'entrée de la rainure 14. Dans 1 'exemple représenté cet organe est constitué par une lame coudée 16 fixée dans le creux de l'épaulement et dirigée vers l'arrière et vers le bas lorsque l'outil est dans sa position de repos. Le fonctionnement de l'outil est alors le suivant.Preferably also, the nose 10 comprises behind the shoulder 10a a retractable elastic member located at the entrance to the groove 14. In the example shown, this member is constituted by a bent blade 16 fixed in the hollow of the shoulder and directed backwards and downwards when the tool is in its rest position. The operation of the tool is then as follows.

Le brin 5b du collier est introduit à l'entrée de la rainure 14 jusqu'à ce que la butée 7 vienne au contact de la surface d'appui lc du sabot. Au cours de ce mouvement, le brin 5b et son bossage 8 ont soulevé la lame élastique 16 dont l'extrémité coudée peut alors prendre appui derrière le bossage 8; le collier est ainsi maintenu dans l'outil et peut, si ce n'est déjà fait, être emmanché sur l'objet à serrer. A cet égard, on soulignera que la coopération du brin 5b avec les flancs de la rainure 14 maintient ce dernier sans une position correcte (fig.2).The strand 5b of the collar is introduced at the entrance to the groove 14 until the stop 7 comes into contact with the bearing surface lc of the shoe. During this movement, the strand 5b and its boss 8 have raised the elastic blade 16 whose bent end can then bear behind the boss 8; the collar is thus held in the tool and can, if it is not already done, be fitted on the object to be tightened. In this regard, it will be emphasized that the cooperation of the strand 5b with the sides of the groove 14 maintains the latter without a correct position (fig. 2).

Lorsque le collier a été amené à sa position d'utilisation sur l'objet à serrer, le moteur d'entraînement de l'organe mobile 3 est mis en route et ce dernier se déplace vers la droite de la figure jusqu'à ce que son nez 10 occupe la position représentée en trait ponctué.When the collar has been brought to its position of use on the object to be tightened, the motor for driving the movable member 3 is started and the latter moves to the right of the figure until its nose 10 occupies the position shown in dotted lines.

Au cours de ce mouvement de l'ogane mobile 3, le nez 10 a quitté son logement 12 et a pivoté sur son articulation 11 pour prendre l'orientation représentée en trait ponctué dans laquelle il se trouve verrouillé par la glissière de l'organe mobile dans le corps. Toutefois, comme on le voit sur la figure 1, l'épaulement 10a évolue dans la rainure 14 et s'est tout d'abord appuyé sur la butée 8. Le brin 5b est entraîné provoquant ainsi le serrage du collier, puisque la butée 7 est immobilisée sur le sabot. Au cours de son mouvement, le brin 5b est guidé par les flancs de la rainure 14 (figure 2).During this movement of the movable ogane 3, the nose 10 has left its housing 12 and has pivoted on its articulation 11 to take the orientation shown in dotted line in which it is locked by the slide of the movable member in the body. However, as can be seen in FIG. 1, the shoulder 10a evolves in the groove 14 and is first of all supported on the stopper 8. The strand 5b is driven thus causing the clamping of the collar, since the stopper 7 is immobilized on the hoof. During its movement, the strand 5b is guided by the sides of the groove 14 (FIG. 2).

Lorsque la traction de l'épaulement 10a sur la butée 8 devient supérieure à une valeur déterminée par la forme et les dimensions de cette butée, celle-ci se trouve arrachée par l'épaulement: 10a et projetée vers l'arrière dans la rainture 14 jusqu'au conduit 15 où elle est évacuée.When the traction of the shoulder 10a on the stop 8 becomes greater than a value determined by the shape and the dimensions of this stop, the latter is torn off by the shoulder: 10a and projected backwards in the rainture 14 to conduit 15 where it is discharged.

Au moment de la rupture de la butée 8, le collier reste serré en raison de la coopération des dents situées sur les deux faces en regard des brins 5a et 5b. L'agrafe 6 évite tout désengagement accidentel de ces dents.When the stop 8 breaks, the collar remains tight due to the cooperation of the teeth located on the two opposite faces of the strands 5a and 5b. The clip 6 prevents any accidental disengagement of these teeth.

L'outil est alors dégagé du brin 5b du collier, cependant qu'un moyen de rappel ramène l'organe mobile dans sa position de repos représentée en trait plein. L'outil est alors prêt à recevoir un autre collier puisque le nez 10 de l'organe mobile, rentré dans son logement 12, a dégagé l'ouverture d'entrée de la rainure 14.The tool is then released from the strand 5b of the collar, while a return means brings the movable member back to its rest position shown in solid lines. The tool is then ready to receive another collar since the nose 10 of the movable member, returned to its housing 12, has cleared the entry opening of the groove 14.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté mais en couvre au contraire toutes les variantes. En particulier on a déjà souligné que le moteur sera avantageusement constitué par un vérin pneumatique, par exemple à double effet,de sorte qu'aucun organe de rappel spécial n'est à prévoir pour ramener l'organe mobile 3 vers l'avant.Of course, the invention is not limited to the embodiment described and shown but on the contrary covers all variants. In particular, it has already been pointed out that the motor will advantageously be constituted by a pneumatic cylinder, for example with double effect, so that no special return member is to be provided for bringing the movable member 3 forward.

De même la partie avant du corps 1 et en particulier le sabot 13 pourront être supprimés, de sorte que le logement 12 sera ouvert vers l'avant. L'opérateur peut ainsi vérifier, après chaque utilisation, que l'équipage mobile est bien revenu à sa position de repos.Likewise the front part of the body 1 and in particular the shoe 13 can be removed, so that the housing 12 will be open towards the front. The operator can thus verify, after each use, that the mobile assembly has indeed returned to its rest position.
