Description

La présente invention se rapporte à un dispositif de pose de fixations, notamment de fixations temporaires de type agrafes d'épinglage.The present invention relates to a device for fixing fasteners, in particular temporary fasteners of the pinning fastener type.

Dans l'industrie aéronautique, avant de réaliser l'assemblage définitif de tôles ou analogues, il est connu de procéder à un assemblage temporaire des tôles au moyen d'agrafes insérées dans des trous traversants.In the aeronautical industry, prior to final assembly of sheets or the like, it is known to temporarily assemble the sheets by means of staples inserted into through holes.

De telles agrafes, par exemple décrites dans le document GB2126146 ou le document EP0336808 , comprennent typiquement :

  • un corps pourvu d'une face d'appui susceptible de venir au contact d'une face avant des structures à assembler,
  • au moins une pince destinée à traverser les perçages et pourvue d'un bec d'accrochage susceptible de s'appliquer contre une face arrière des structures à assembler,
  • un mécanisme déplaçable par rapport au corps, le mécanisme comprenant une tige filetée disposée coaxialement au corps, une extrémité de la tige étant prolongée par la pince, le mécanisme comprenant en outre un écrou de commande monté sur une autre extrémité de la tige.
Such staples, for example described in the document GB2126146 or the document EP0336808 , typically include:
  • a body provided with a bearing face capable of coming into contact with a front face of the structures to be assembled,
  • at least one clamp intended to pass through the bores and provided with a catching nose which can be applied against a rear face of the structures to be assembled,
  • a mechanism movable relative to the body, the mechanism comprising a threaded rod disposed coaxially with the body, one end of the rod being extended by the clamp, the mechanism further comprising a control nut mounted on another end of the rod.

Ces agrafes sont généralement posées sur les tôles à l'aide d'un appareil moteur de type visseuse/dévisseuse, muni d'un dispositif de pose comprenant :

  • un premier fourreau cylindrique qui immobilise en translation le corps d'une agrafe après son insertion,
  • un deuxième fourreau cylindrique logé dans le premier fourreau, permettant de bloquer en rotation le corps de l'agrafe,
  • un troisième fourreau cylindrique logé dans le deuxième fourreau, le troisième fourreau étant entraîné en rotation par l'appareil moteur, une extrémité du troisième fourreau entraînant en rotation l'écrou de commande de l'agrafe.
These staples are generally placed on the sheets using a screwdriver / stripper-type motor apparatus, provided with a laying device comprising:
  • a first cylindrical sleeve that immobilizes in translation the body of a staple after insertion,
  • a second cylindrical sleeve housed in the first sleeve, for locking the body of the clip in rotation,
  • a third cylindrical sleeve housed in the second sleeve, the third sleeve being rotated by the motor apparatus, one end of the third sleeve rotating the control nut of the clip.

Un tel dispositif de pose est notamment décrit dans le document EP0466609 .Such a laying device is described in particular in the document EP0466609 .

Entraîné en rotation, l'écrou déplace en translation la tige filetée de l'agrafe, de sorte que les becs d'accrochage et la face d'appui du corps s'appliquent respectivement sur les faces arrière et avant des tôles empilées. Un couple de serrage déterminé est généralement appliqué à l'agrafe lors de sa pose.Driven in rotation, the nut moves in translation the threaded rod of the staple, so that the catching nose and the bearing surface of the body respectively apply to the rear and front faces of the stacked sheets. A determined tightening torque is generally applied to the staple during its installation.

Les deuxième et troisième fourreaux du dispositif de pose sont munis de moyens d'entraînement/ de blocage en rotation, respectivement du corps et de l'écrou de l'agrafe. Lorsque le corps ou l'écrou a une section polygonale, ces moyens d'entraînement/ de blocage peuvent être formés par une empreinte de forme complémentaire.The second and third sleeves of the laying device are provided with means for driving / locking in rotation, respectively of the body and the nut of the clip. When the body or the nut has a polygonal section, these drive / locking means may be formed by a complementary shape impression.

En revanche, lorsque le corps ou l'écrou a une section circulaire, il convient d'utiliser un système d'entraînement par coincement, de type cage à galets. Un tel système de cage à galets est notamment décrit dans le document EP0466609 .On the other hand, when the body or the nut has a circular section, it is advisable to use a wedge-type drive system, like a roller cage. Such a roller cage system is described in particular in the document EP0466609 .

La cage à galets est typiquement installée libre en rotation dans un logement de section polygonale, dont les pans coopèrent avec les galets durant le fonctionnement du dispositif de pose.The roller cage is typically installed free to rotate in a housing of polygonal section, whose sides cooperate with the rollers during operation of the laying device.

Or, selon la position angulaire des galets par rapport aux pans, des problèmes peuvent survenir lors de l'installation des fixations temporaires. Un mauvais positionnement peut induire des frottements excessifs, qui perturbent l'installation des fixations et/ou génèrent des dégâts au niveau de l'écrou de commande.However, depending on the angular position of the rollers relative to the panels, problems may arise during the installation of the temporary fasteners. Improper positioning may induce excessive friction, which disturbs the installation of the fasteners and / or causes damage to the control nut.

En cas de pose manuelle des agrafes, les opérateurs sont capables de manipuler judicieusement le dispositif de pose, afin de contourner ces problèmes. Cependant, en utilisation automatique, les robots de pose n'ont actuellement pas de telles compétences.In the case of manual stapling, the operators are able to handle the laying device wisely in order to circumvent these problems. However, in automatic use, laying robots currently do not have such skills.

Il est donc nécessaire d'éviter, dans le dispositif de pose, un mauvais positionnement de la cage à galets au moment de l'insertion d'une fixation temporaire dans le dispositif.It is therefore necessary to avoid, in the laying device, a bad positioning of the roller cage at the time of the insertion of a temporary attachment into the device.

La présente invention vise à résoudre ce problème en munissant le dispositif de pose d'un moyen de positionnement optimal de la cage à galets.The present invention aims to solve this problem by providing the laying device with an optimal positioning means of the roller cage.

Plus précisément, la présente invention se rapporte à un outil de pose de fixations, ledit outil comprenant : un fourreau disposé selon un axe principal, ledit fourreau ménageant un logement interne cylindrique de base polygonale, se développant selon l'axe principal ; une cage à galets, reçue dans ledit logement cylindrique, ladite cage comprenant : un support cylindrique de base sensiblement circulaire, disposé selon l'axe principal, une surface latérale externe dudit support étant sensiblement tangente à des faces latérales du logement cylindrique de base polygonale ; des galets disposés sur le pourtour du support, chaque galet étant mobile en rotation par rapport audit support selon un axe parallèle à l'axe principal ; un ressort de compression exerçant sur les galets un effort radial en direction de l'axe principal ; la cage étant configurée de sorte que chaque galet est logé au niveau d'une arête du logement cylindrique du fourreau ; le support de la cage étant apte à pivoter selon l'axe principal à l'intérieur dudit logement cylindrique. L'outil de pose comprend en outre un élément de rappel, relié d'une part à un galet de la cage et d'autre part au fourreau, ledit élément de rappel tendant à ramener les galets de la cage en regard des arêtes du logement cylindrique du fourreau.More specifically, the present invention relates to a fastening tool, said tool comprising: a sheath disposed along a main axis, said sheath providing a cylindrical inner housing of polygonal base, developing along the main axis; a roller cage received in said cylindrical housing, said cage comprising: a substantially circular base cylindrical support disposed along the main axis, an external lateral surface of said support being substantially tangential to side faces of the polygonal base cylindrical housing; rollers disposed on the periphery of the support, each roller being rotatable relative to said support along an axis parallel to the main axis; a compression spring exerting on the rollers a radial force towards the main axis; the cage being configured so that each roller is housed at an edge of the cylindrical housing of the sleeve; the support of the cage being able to pivot along the main axis inside said cylindrical housing. The laying tool further comprises a return element, connected on the one hand to a roller of the cage and on the other hand to the sheath, said return element tending to bring the rollers of the cage opposite the edges of the housing cylindrical sheath.

Préférentiellement, l'élément de rappel est un ressort de torsion.Preferably, the return element is a torsion spring.

Ainsi, bien que la cage à galets se déplace en rotation dans son logement durant la pose des agrafes, l'élément de rappel ramène la cage dans sa position optimale à la fin de l'installation.Thus, although the roller cage rotates in its housing during the installation of the staples, the return element brings the cage back to its optimum position at the end of the installation.

Dans le cadre de l'invention, le terme « outil » s'entend comme un dispositif complet de pose, ou encore comme une partie dudit dispositif, telle qu'une clé d'entraînement de l'écrou de commande.In the context of the invention, the term "tool" is understood as a complete laying device, or as a part of said device, such as a drive key of the control nut.

Préférentiellement, l'outil est destiné à la pose de fixations temporaires comprenant : un corps longitudinal pourvu d'une face frontale, au moins une pince émergeant de ladite face frontale, une tige filetée coaxiale au corps et mobile en translation selon ledit axe, une extrémité de la tige étant prolongée par la pince, un écrou de commande monté sur une autre extrémité de la tige.Preferably, the tool is intended for the installation of temporary fasteners comprising: a longitudinal body provided with a front face, at least one clamp emerging from said front face, a threaded rod coaxial with the body and movable in translation along said axis, a end of the rod being extended by the clamp, a control nut mounted on another end of the rod.

Un tel outil de pose peut également être adapté pour installer un écrou d'assemblage à forme externe cylindrique, ainsi que toute fixation incorporant un tel écrou.Such an installation tool can also be adapted to install a cylindrical outer form of assembly nut, as well as any fastener incorporating such a nut.

Selon un mode de réalisation de l'invention, l'écrou est de section circulaire et l'outil est configuré de sorte que l'écrou puisse être inséré dans la cage à galets, une surface latérale externe de l'écrou venant alors au contact des galets. Dans ce mode de réalisation, l'outil est par exemple une clé d'entraînement de l'écrou.According to one embodiment of the invention, the nut is of circular section and the tool is configured so that the nut can be inserted into the roller cage, an outer lateral surface of the nut then coming into contact shingles. In this embodiment, the tool is for example a drive key of the nut.

Préférentiellement, un autre élément de l'outil ou du dispositif complet de pose comprend un moyen de retenue en rotation du corps longitudinal.Preferably, another element of the tool or of the complete laying device comprises a retaining means in rotation of the longitudinal body.

Selon un autre mode de réalisation de l'invention, le corps longitudinal a une extrémité de section circulaire et l'outil est configuré de sorte que ladite extrémité puisse être insérée dans la cage à galets, une surface latérale externe de ladite extrémité venant alors au contact des galets. Dans ce mode de réalisation, l'outil est par exemple une partie avant, ou nez, d'un appareil de type visseuse/dévisseuse.According to another embodiment of the invention, the longitudinal body has a circular end of section and the tool is configured so that said end can be inserted into the roller cage, an outer lateral surface of said end then coming to contact of pebbles. In this embodiment, the tool is for example a front part, or nose, of a screwdriver / unscrewing device.

Préférentiellement, un autre élément de l'outil ou du dispositif complet de pose comprend un moyen d'entraînement en rotation de l'écrou.Preferably, another element of the tool or of the complete laying device comprises means for driving the nut in rotation.

The first sheath 12 delimits a first internal cavity in which is disposed along the axis 11 a second sheath 13.

La translation du corps de l'agrafe 50 en direction de la face d'appui 52 est bloquée par le premier fourreau 12, venant en butée axiale contre l'extrémité 59 du corps 51.The translation of the body of the staple 50 in the direction of the bearing face 52 is blocked by the first sleeve 12, coming into axial abutment against the end 59 of the body 51.

Le deuxième fourreau 13 est configuré de sorte à coopérer avec l'extrémité 59 pour immobiliser le corps 51 en rotation selon l'axe 11. L'extrémité 59 a par exemple une section de forme hexagonale ; à proximité d'une ouverture axiale 20, le deuxième fourreau 13 présente une paroi interne 14 de forme complémentaire à cette section.The second sleeve 13 is configured to cooperate with the end 59 to immobilize the body 51 in rotation along the axis 11. The end 59 has for example a section of hexagonal shape; near an axial opening 20, the second sleeve 13 has an inner wall 14 of complementary shape to this section.

Le deuxième fourreau 13 délimite une deuxième cavité interne, dans laquelle l'extrémité 59 du corps 51 est insérée, tandis que le reste du corps émerge à l'extérieur du dispositif 10 par l'ouverture axiale 20.The second sleeve defines a second internal cavity, in which the end 59 of the body 51 is inserted, while the rest of the body emerges outside the device 10 through the axial opening 20.

Le dispositif 10 de pose comprend en outre un manchon 15, logé dans la deuxième cavité interne. Le manchon 15 est mobile en rotation et en translation dans ladite deuxième cavité interne, selon l'axe 11.The laying device 10 further comprises a sleeve 15, housed in the second internal cavity. The sleeve 15 is movable in rotation and in translation in said second internal cavity along the axis 11.

Le manchon 15 forme une troisième cavité interne 17, ouverte aux deux extrémités du manchon selon l'axe 11. Une portion de la cavité 17 forme un logement 18, dont la paroi latérale est cylindrique de base polygonale, se développant selon l'axe 11. Le logement 18 a par exemple une surface latérale à douze pans, c'est-à-dire une section formant un dodécagone régulier.The sleeve 15 forms a third internal cavity 17, open at both ends of the sleeve along the axis 11. A portion of the cavity 17 forms a housing 18, whose lateral wall is cylindrical with a polygonal base, developing along the axis 11 The housing 18 has for example a twelve-sided lateral surface, that is to say a section forming a regular dodecagon.

Le logement 18 reçoit une cage 19 à galets, dont le fonctionnement sera détaillé plus bas.The housing 18 receives a roll cage 19, the operation of which will be detailed below.

Une extrémité 21 de la cavité 17 reçoit un arbre 22 d'entraînement, destiné à être relié à un arbre de sortie d'un dispositif de vissage/dévissage. Le manchon 15 est mobile en translation selon l'axe 11 par rapport à l'arbre 22, qui est pour sa part fixe en translation par rapport au premier fourreau 12. Un ressort 23 de compression, logé dans l'extrémité 21 de la cavité 17 et appuyé contre l'arbre 22, tend à ramener le manchon 15 vers l'ouverture 20.An end 21 of the cavity 17 receives a drive shaft 22 intended to be connected to an output shaft of a screwing / unscrewing device. The sleeve 15 is movable in translation along the axis 11 relative to the shaft 22, which is fixed in translation relative to the first sleeve 12. A compression spring 23, housed in the end 21 of the cavity 17 and pressed against the shaft 22, tends to bring the sleeve 15 towards the opening 20.

L'arbre 22 peut entraîner en rotation le manchon 15, selon l'axe 11, au moyen d'une goupille 24.The shaft 22 can rotate the sleeve 15, along the axis 11, by means of a pin 24.

La figure 2 montre une vue éclatée d'un manchon 15 analogue au manchon 15 de la figure 1. Les numéros de référence sont conservés par rapport à la figure 1.The figure 2 shows an exploded view of a sleeve 15 similar to the sleeve 15 of the figure 1 . The reference numbers are kept in relation to the figure 1 .

Le manchon 15, ou clé d'entraînement, comprend un fourreau 16 disposé selon un axe 11 principal, ledit fourreau ménageant une cavité interne. Une portion de ladite cavité interne forme un logement 18, cylindrique de base polygonale, se développant selon l'axe 11. Comme dans le cas de la figure 1, la base polygonale est par exemple un dodécagone régulier.The sleeve 15, or drive key, comprises a sleeve 16 disposed along a main axis 11, said sleeve providing an internal cavity. A portion of said internal cavity forms a housing 18, cylindrical polygonal base, developing along the axis 11. As in the case of the figure 1 , the polygonal base is for example a regular dodecagon.

Sur la figure 2, on observe également une perforation transversale 25 du fourreau 16, destinée à recevoir la goupille 24 décrite précédemment.On the figure 2 , there is also a transverse perforation 25 of the sleeve 16, intended to receive the pin 24 described above.

Le logement cylindrique 18 reçoit une cage 19 à galets. Ladite cage est formée d'une bague 30 et d'un anneau élastique 31, disposés selon l'axe 11 et reliés par des entretoises 32. La bague 30, l'anneau 31 et les entretoises 32 forment un support cylindrique 33 de base sensiblement circulaire. Le support 33 est configuré de sorte à ce que les entretoises 32 soient sensiblement tangentes à des faces latérales 26 du logement 18.The cylindrical housing 18 receives a cage 19 with rollers. Said cage is formed of a ring 30 and an elastic ring 31, arranged along the axis 11 and connected by spacers 32. The ring 30, the ring 31 and the spacers 32 form a cylindrical support 33 of base substantially circular. The support 33 is configured so that the spacers 32 are substantially tangent to side faces 26 of the housing 18.

La cage 19 comprend en outre des galets 34 disposés sur le pourtour du support 33, entre les entretoises 32. Chaque galet 34 est mobile en rotation par rapport au support 33 selon un axe 35 parallèle à l'axe principal 11. Dans l'exemple de la figure 2, les galets 34 sont répartis sur six axes 35, disposés autour de l'axe 11 selon un hexagone régulier.The cage 19 further comprises rollers 34 disposed on the periphery of the support 33, between the spacers 32. Each roller 34 is rotatable relative to the support 33 along an axis 35 parallel to the main axis 11. In the example of the figure 2 the rollers 34 are distributed over six axes 35, arranged around the axis 11 in a regular hexagon.

Par ailleurs, la cage 19 comprend un ressort 36 de compression, disposé autour des entretoises et des galets. Le ressort 36 exerce sur les galets 34 un effort radial en direction de l'axe 11.Furthermore, the cage 19 comprises a compression spring 36 disposed around the spacers and rollers. The spring 36 exerts on the rollers 34 a radial force towards the axis 11.

Lorsque l'agrafe 50 est insérée dans le dispositif 10 en vue de sa pose (voir figure 1), l'écrou 57 de commande, de section circulaire, vient se loger dans la cage à galets 19 du manchon. Le ressort 36 permet aux galets 34 de se plaquer radialement contre la surface latérale de l'écrou 57. Lorsque le fourreau 16 est entraîné en rotation par l'arbre 22, les faces latérales 26, ou pans du logement 18 coopèrent avec les galets 34, qui eux-mêmes coopèrent avec la surface latérale de l'écrou 57. L'écrou est entraîné en rotation par coincement des galets 34 entre les pans 26 et ledit écrou.When the staple 50 is inserted into the device 10 for its installation (see figure 1 ), the control nut 57, of circular section, is housed in the roll cage 19 of the sleeve. The spring 36 allows the rollers 34 to be pressed radially against the lateral surface of the nut 57. When the sleeve 16 is rotated by the shaft 22, the side faces 26, or sides of the housing 18 cooperate with the rollers 34 , which themselves cooperate with the lateral surface of the nut 57. The nut is rotated by wedging the rollers 34 between the panels 26 and said nut.

Les figures 3A et 3B montrent des vues en coupe transversale de la clé d'entraînement 15 dans laquelle est insérée l'agrafe 50. Le plan de coupe passe par la cage 19 à galets et par l'écrou 57.The Figures 3A and 3B show cross-sectional views of the drive key 15 into which the staple 50 is inserted. The cutting plane passes through the roller cage 19 and the nut 57.

La figure 3A montre la clé d'entraînement 15 dans une configuration avant vissage/dévissage, permettant une installation correcte de l'agrafe 50. En médaillon, une vue détaillée d'un galet 34 est présentée.The figure 3A shows the drive key 15 in a configuration before screwing / unscrewing, allowing proper installation of the staple 50. Inset, a detailed view of a roller 34 is shown.

Dans la configuration de la figure 3A, chacun des galets 34 se trouve en regard d'une arête 27 délimitant deux pans 26 latéraux du logement 18. Plus précisément, chaque axe 35 de rotation d'un galet se trouve inclus dans un plan passant par l'axe 11 principal et par une arête 27.In the configuration of the figure 3A each of the rollers 34 is opposite an edge 27 delimiting two lateral panels 26 of the housing 18. More specifically, each axis 35 of rotation of a roller is included in a plane passing through the main axis 11 and by a ridge 27.

Le logement 18 comprenant douze pans 26 et douze arêtes 27, une arête sur deux se trouve en regard d'un galet 34. Il existe un jeu 40 entre chaque galet 34 et l'arête 27 en vis-à-vis. Cette configuration de la cage 19 permet à la clé d'entraînement 15 d'exercer sur l'écrou 57 un effort optimal lors du vissage.The housing 18 comprising twelve sections 26 and twelve edges 27, one edge in two is opposite a roller 34. There is a clearance 40 between each roller 34 and the edge 27 vis-à-vis. This configuration of the cage 19 allows the drive key 15 to exert on the nut 57 an optimal effort during screwing.

La figure 3B montre la clé d'entraînement 15 dans une autre configuration avant vissage/dévissage, cette configuration étant défavorable à l'installation correcte de l'agrafe 50. Dans cette configuration, les galets 34 sont décalés par rapport aux arêtes 27. Chaque galet 34 est en contact avec un unique pan 26 du logement 18, sans jeu.The figure 3B shows the drive key 15 in another configuration before screwing / unscrewing, this configuration being unfavorable to the correct installation of the staple 50. In this configuration, the rollers 34 are offset with respect to the edges 27. Each roller 34 is in contact with a single pan 26 of housing 18, without play.

Dans les dispositifs de l'art antérieur, la cage à galets est libre en rotation selon l'axe principal dans le logement de section polygonale. Il est donc possible que la cage se trouve dans la configuration de la figure 3B lors de l'insertion d'un écrou de commande.In the devices of the prior art, the roller cage is free to rotate along the main axis in the housing of polygonal section. It is therefore possible that the cage is in the configuration of the figure 3B when inserting a control nut.

Une telle configuration induit des efforts excessifs durant l'installation de l'agrafe 50. Dans le cas où le dispositif 10 exerce un effort insuffisant sur la clé 15, l'entraînement de l'écrou en rotation est défectueux. En cas d'efforts plus élevé exercé par le dispositif 10, l'écrou 57 peut se retrouver endommagé par les frottements des galets 34.Such a configuration induces excessive forces during the installation of the staple 50. In the case where the device 10 exerts insufficient effort on the key 15, the drive of the rotating nut is defective. In the event of greater forces exerted by the device 10, the nut 57 can be damaged by the friction of the rollers 34.

La présente invention inclut donc un moyen de ramener les galets dans la position de la figure 3A avant toute insertion d'une fixation temporaire dans la cage à galets.The present invention thus includes a means of bringing the rollers back into the position of the figure 3A before any insertion of a temporary fixation into the roller cage.

Dans l'exemple de la figure 2, ce moyen est matérialisé par un ressort 37 de torsion. Le ressort 37 a la forme d'un fil enroulé selon l'axe 11. Une première extrémité 38 du ressort 37 est reliée à un galet 34 de la cage 19. Une seconde extrémité 39 du ressort 37 est reliée au fourreau 16. L'extrémité 39 est par exemple logée dans une encoche radiale (non représentée) ménagée sur une surface interne du fourreau.In the example of the figure 2 this means is embodied by a torsion spring 37. The spring 37 has the shape of a wire wound along the axis 11. A first end 38 of the spring 37 is connected to a roller 34 of the cage 19. A second end 39 of the spring 37 is connected to the sheath 16. The end 39 is for example housed in a radial notch (not shown) formed on an inner surface of the sheath.

Le ressort 37 tend à placer les galets 34 de la cage 19 dans la configuration représentée à la figure 3A, lesdits galets étant en regard d'une arête 27.The spring 37 tends to place the rollers 34 of the cage 19 in the configuration shown in FIG. figure 3A said rollers being opposite an edge 27.

Lorsqu'un couple de vissage/dévissage est appliqué à la clé 15, une déformation du ressort 37 a lieu par inertie de la cage 19, assurant l'entraînement en rotation de l'écrou 57. Lors de l'arrêt du vissage/dévissage, le ressort 37 fait pivoter la cage 19 pour la remettre dans sa configuration initiale, telle que représentée à la figure 3A.When a screwing / unscrewing torque is applied to the wrench 15, a deformation of the spring 37 takes place by inertia of the cage 19, ensuring the drive in rotation of the nut 57. When stopping the screwing / unscrewing , the spring 37 rotates the cage 19 to return it to its initial configuration, as represented in FIG. figure 3A .

Ainsi, avant toute insertion d'une agrafe 50 dans le dispositif 10 de la figure 1, la position de la cage 19 dans la clé 15 est nécessairement optimale à l'installation de ladite agrafe.Thus, before any insertion of a staple 50 into the device 10 of the figure 1 , the position of the cage 19 in the key 15 is necessarily optimal at the installation of said staple.

La figure 4 représente une vue détaillée d'une variante de réalisation de l'invention. Plus précisément, la figure 4 représente une vue détaillée d'une agrafe 50' analogue à l'agrafe 50 représentée à la figure 1, insérée dans un dispositif 10' de pose analogue au dispositif 10 de la figure 1. Les références des éléments communs avec ceux de la figure 1 sont conservées ci-après.The figure 4 represents a detailed view of an alternative embodiment of the invention. More specifically, the figure 4 represents a detailed view of a staple 50 'similar to the staple 50 shown in FIG. figure 1 inserted in a laying device 10 'similar to the device 10 of the figure 1 . The references of the elements common with those of the figure 1 are preserved below.

Une différence entre l'agrafe 50' et l'agrafe 50 de la figure 1 est la forme d'un écrou 57' de commande, analogue à l'écrou 57. Plus précisément, l'écrou 57' présente une section hexagonale et non circulaire.A difference between the staple 50 'and the staple 50 of the figure 1 is the shape of a control nut 57 ', similar to the nut 57. More specifically, the nut 57' has a hexagonal and non-circular section.

Sur la figure 4, l'écrou 57' est logé dans un manchon 15' analogue au manchon 15. Plus précisément, le manchon 15' comporte un logement 18' dont la forme est complémentaire de celle de l'écrou 57'. Le logement 18' a donc une forme cylindrique de base hexagonale. Lors de la mise en rotation du manchon 15', la surface du logement 18' coopère directement avec l'écrou 57' pour l'entraîner en rotation.On the figure 4 , the nut 57 'is housed in a sleeve 15' similar to the sleeve 15. More specifically, the sleeve 15 'has a housing 18' whose shape is complementary to that of the nut 57 '. The housing 18 'therefore has a cylindrical shape of hexagonal base. During the rotation of the sleeve 15 ', the surface of the housing 18' cooperates directly with the nut 57 'to drive it in rotation.

Une autre différence entre l'agrafe 50' et l'agrafe 50 est la forme d'une extrémité 59' du corps 51. Dans l'exemple de la figure 4, l'extrémité 59' présente une section circulaire, contrairement à la forme à six pans de l'extrémité 59 de la figure 1.Another difference between the staple 50 'and the staple 50 is the shape of an end 59' of the body 51. In the example of the figure 4 , the end 59 'has a circular section, unlike the hexagonal shape of the end 59 of the figure 1 .

Comme dans l'exemple de la figure 1, un deuxième fourreau 13' du dispositif 10' coopère avec l'extrémité 59' pour immobiliser le corps 51 en rotation selon l'axe 11. A proximité d'une ouverture axiale, le deuxième fourreau 13' présente un logement interne 14', de même forme que le logement 18 des figures 1 et 2. Ce logement 14' contient une cage à galets 19, identique à celle décrite précédemment à l'appui des figures 1 et 2.As in the example of figure 1 a second sleeve 13 'of the device 10' cooperates with the end 59 'to immobilize the body 51 in rotation along the axis 11. Near an axial opening, the second sheath 13 'has an internal housing 14', of the same shape as housing 18 of Figures 1 and 2 . This housing 14 'contains a roller cage 19, identical to that described above in support of Figures 1 and 2 .

Les autres éléments du dispositif 10' et de l'agrafe 50' sont identiques à ceux du dispositif 10 et de l'agrafe 50 représentés à la figure 1.The other elements of the device 10 'and the staple 50' are identical to those of the device 10 and the staple 50 shown in FIG. figure 1 .

Lors de l'entraînement en rotation de l'écrou 57', l'extrémité 59' du corps 51 est bloquée en rotation par coincement des galets de la cage 19 contre les pans du logement interne 14', de manière identique à celle décrite ci-dessus. L'écrou 57' peut alors se déplacer le long de la tige filetée 55 pour l'installation de l'agrafe 50'.During the rotational drive of the nut 57 ', the end 59' of the body 51 is locked in rotation by wedging the rollers of the cage 19 against the sides of the inner housing 14 ', in a manner identical to that described herein. -above. The nut 57 'can then move along the threaded rod 55 for the installation of the staple 50'.

Pour des raisons identiques à celle décrites ci-dessus, une installation optimale de l'agrafe 50' nécessite que la cage 19 de la figure 4 se trouve dans la configuration représentée à la figure 3A avant insertion de l'extrémité 59' du corps 51, qui prend alors la place de l'écrou 57. La cage 19 de la figure 4 inclut donc un ressort 37 identique à celui décrit précédemment, ledit ressort assurant le retour de la cage 19 dans sa configuration optimale à la fin de l'installation de l'agrafe 50'.For reasons identical to those described above, an optimal installation of the staple 50 'requires that the cage 19 of the figure 4 is in the configuration shown in the figure 3A before insertion of the end 59 'of the body 51, which then takes the place of the nut 57. The cage 19 of the figure 4 therefore includes a spring 37 identical to that described above, said spring ensuring the return of the cage 19 in its optimal configuration at the end of the installation of the staple 50 '.

Il est également possible d'envisager une agrafe comprenant un écrou 57 circulaire et une extrémité 59' circulaire au corps 51. Dans ce cas, il est possible de combiner les exemples des figures 1 et 4, afin que ledit écrou 57 et ladite extrémité 59' coopèrent chacun avec une cage à galets 19 telle que décrite précédemment, chaque cage revenant dans sa position initiale après installation, à l'aide d'un ressort de torsion.It is also possible to envisage a staple comprising a circular nut 57 and a circular end 59 'to the body 51. In this case, it is possible to combine the examples of the figures 1 and 4 , so that said nut 57 and said end 59 'each cooperate with a roller cage 19 as described above, each cage returning to its initial position after installation, using a torsion spring.

Bien que l'élément de rappel de l'invention ait été décrit dans les exemples comme étant formé par un ressort de torsion, il est entendu que cet exemple n'est pas restrictif. Tout moyen équivalent permettant de ramener les galets de la cage en regard des arêtes du logement cylindrique du fourreau est compris dans l'invention.Although the biasing element of the invention has been described in the examples as being formed by a torsion spring, it will be understood that this example is not restrictive. Any equivalent means for bringing the rollers of the cage opposite the edges of the cylindrical housing of the sheath is included in the invention.
