La patte 14 est à cet effet montée rotative sur le corps 12 entre une position d'insertion et de retrait de l'attache à travers la paroi 8, dans laquelle la patte 14 ne fait sensiblement pas saillie radialement par rapport au corps 12, et une position déployée de retenue de la structure 4 (figures 3 et 4bis), dans laquelle la patte 14 est déployée radialement par rapport au corps 12.For this purpose, the lug 14 is rotatably mounted on the body 12 between a position of insertion and withdrawal of the fastener through the wall 8, in which the lug 14 does not substantially project radially relative to the body 12, and a deployed position of retaining structure 4 ( figures 3 and 4a ), in which the tab 14 is deployed radially with respect to the body 12.

L'attache 10 comprend également des moyens de fixation sur la paroi 8, dont un écrou 18 de serrage, destiné à être serré vers la face intérieure 6B de la paroi 8, et un loquet 22 monté déployable et destiné à serrer la face opposée 6A de la paroi 8.The fastener 10 also comprises fastening means on the wall 8, including a tightening nut 18, intended to be clamped towards the inner face 6B of the wall 8, and a latch 22 mounted to deploy and intended to tighten the opposite face 6A. of the wall 8.

L'écrou 18 est vissé sur une partie proximale filetée 12B du corps 12 (à gauche sur les dessins), qui s'étend suivant un axe longitudinal A. L'écrou 18 est ainsi mobile en translation le long de l'axe A par rapport au corps 12 pour serrer l'attache 10 sur la paroi 8.The nut 18 is screwed onto a threaded proximal portion 12B of the body 12 (on the left in the drawings), which extends along a longitudinal axis A. The nut 18 is thus movable in translation along the axis A through relative to the body 12 to tighten the fastener 10 on the wall 8.

L'écrou 18 présente une tête 23 de manoeuvre conformée pour un actionnement manuel depuis l'extrémité proximale 10B de l'attache 10. La tête 23 présente à cet effet plusieurs doigts 23' en saillie radiale, à savoir trois doigts 23' agencés à 120° dans l'exemple illustré.The nut 18 has an actuating head 23 shaped for manual actuation from the proximal end 10B of the fastener 10. The head 23 has for this purpose several fingers 23 'projecting radially, namely three fingers 23' arranged at 120 ° in the illustrated example.

L'attache 10 comporte également une tige 24 d'actionnement de la patte 14 et du loquet 22 pour déplacer ces derniers entre leur position d'insertion et leur position déployée respectives.The fastener 10 also comprises a rod 24 for actuating the tab 14 and the latch 22 to move the latter between their respective insertion position and their deployed position.

La tige 24 est à cet effet montée coulissante le long de l'axe A à l'intérieur de la partie proximale 12B du corps 12 (Figure 2) et solidaire en rotation du corps 12 autour de l'axe A, par clavetage des deux extrémités proximales.The rod 24 is slidably mounted along the axis A inside the proximal portion 12B of the body 12 (FIG. Figure 2 ) and integral in rotation of the body 12 about the axis A, by locking the two proximal ends.

La tige 24 est munie à son extrémité proximale 24B d'une poignée 26 s'étendant à l'extérieur du corps 12. La poignée 26 est solidaire en rotation de la tige 24 et conformée pour permettre d'indiquer à l'opérateur l'orientation de la patte 14 située de l'autre côté de la paroi 8. Dans l'exemple illustré, une orientation de la poignée 26 vers le bas correspond à une orientation vers le haut de la patte 14.The rod 24 is provided at its proximal end 24B with a handle 26 extending outside the body 12. The handle 26 is rotationally integral with the rod 24 and shaped to enable the operator to be informed of the orientation of the tab 14 located on the other side of the wall 8. In the illustrated example, an orientation of the handle 26 downwards corresponds to an upward orientation of the tab 14.

La tige 24 est munie, à son extrémité distale 24A, d'un coulisseau 28 monté solidaire de la tige 24 et coulissant à l'intérieur d'une partie distale 12A du corps 12. En variante, la tige 24 et le coulisseau 28 sont formés en une seule pièce.The rod 24 is provided, at its distal end 24A, with a slide 28 mounted integral with the rod 24 and sliding inside a distal portion 12A of the body 12. In a variant, the rod 24 and the slide 28 are formed in one piece.

La translation de la tige 24 dans un premier sens le long de l'axe B, à savoir vers l'extrémité distale 10A de l'attache 10 dans l'exemple illustré, déploie automatiquement le loquet 22 et la patte 14, tandis que la translation de la tige 24 dans le sens opposé les déplace automatiquement vers leur position d'insertion et de retrait.The translation of the rod 24 in a first direction along the axis B, namely towards the distal end 10A of the fastener 10 in the illustrated example, automatically deploys the latch 22 and the tab 14, while the translation of the stem 24 in the opposite direction automatically moves them to their insertion and removal position.

La tige 24 est sollicitée élastiquement par un ressort 31 vers la droite, dans le sens du déploiement automatique du loquet 22 et de la patte 14.The rod 24 is resiliently biased by a spring 31 to the right, in the direction of the automatic deployment of the latch 22 and the tab 14.

La partie distale 12A du corps 12 délimite une portée 29 d'appui contre la surface intérieure de l'orifice traversant 11 de la paroi 8, au niveau de son extrémité distale 11A.The distal portion 12A of the body 12 delimits a bearing surface 29 against the inner surface of the through-orifice 11 of the wall 8, at its distal end 11A.

La partie distale 12A du corps 12 est d'axe longitudinal B. La partie distale 12A est ainsi conformée de façon sensiblement coaxiale à la partie proximale 12B.The distal portion 12A of the body 12 is of longitudinal axis B. The distal portion 12A is thus shaped substantially coaxially with the proximal portion 12B.

Le loquet 22 et la patte 14 sont prévus sur la partie distale 12A. La patte 14 chevauche d'ailleurs la partie distale 12A. La patte 14 a, à cet effet, une section transversale en forme de U.The latch 22 and the tab 14 are provided on the distal portion 12A. The tab 14 also overlaps the distal portion 12A. The tab 14 has, for this purpose, a U-shaped cross section.

L'attache 10 présente plusieurs particularités remarquables, qui vont être décrites ci-dessous.The clip 10 has several remarkable features, which will be described below.

L'attache 10 illustrée sur les figures 2 à 4bis est tout d'abord remarquable en ce qu'elle comprend un tampon ou manchon élastomère 32 d'appui axial et radial dans l'orifice 11 de la paroi 8.The clip 10 illustrated on the Figures 2 to 4bis is firstly remarkable in that it comprises an elastomeric buffer or sleeve 32 for axial and radial support in the orifice 11 of the wall 8.

Le tampon 32 est monté mobile en translation le long du corps 12 pour serrer l'attache 10 sur la paroi 8.The buffer 32 is mounted to move in translation along the body 12 to clamp the fastener 10 on the wall 8.

L'écrou 18 assure le déplacement en translation du tampon 32 le long du corps 12. Le tampon 32 est en effet agencé de façon distale par rapport à l'écrou 18 de façon à ce que le tampon 32 soit poussé par l'écrou 18 dans l'orifice 11 lors du vissage de l'écrou 18.The nut 18 moves the buffer 32 in translation along the body 12. The pad 32 is in fact arranged distally with respect to the nut 18 so that the pad 32 is pushed by the nut 18 in the orifice 11 during screwing of the nut 18.

Le tampon 32 délimite une portée 34 d'appui axial contre la surface interne de l'orifice traversant 11. La portée 34 est conformée pour que le rapprochement relatif du tampon 32 et du loquet 22 assure le serrage axial de la paroi 8 entre le tampon 32 et le loquet 22.The buffer 32 delimits a bearing surface 34 of axial support against the inner surface of the through orifice 11. The bearing surface 34 is shaped so that the relative approximation of the buffer 32 and the latch 22 ensures the axial clamping of the wall 8 between the buffer 32 and the latch 22.

La portée 34 est conique et convergente vers l'extrémité distale de l'attache 10. Elle est de forme complémentaire de l'orifice 11. L'orifice 11a, dans l'exemple illustré, une forme conique et convergente vers son extrémité distale 11 A.The bearing surface 34 is conical and convergent towards the distal end of the fastener 10. It is of complementary shape to the orifice 11. The orifice 11a, in the illustrated example, a conical and convergent shape toward its distal end 11 AT.

La portée 34 a en variante une autre forme de tout type adapté pour assurer l'immobilisation axiale et radiale du tampon 32 contre la surface interne de l'orifice 11. Il peut s'agir par exemple d'une forme pyramidale tronquée.The scope 34 has alternatively another form of any type adapted to ensure the axial and radial immobilization of the buffer 32 against the inner surface of the orifice 11. It may be for example a truncated pyramidal shape.

Dans l'exemple illustré, le tampon 32 est un manchon fixé sur un support 36 lui-même monté coulissant et libre en rotation autour de la partie proximale 12B du corps 12. Le support 36 délimite une portée 36B recevant les efforts d'appui de l'écrou 18. En variante, le tampon 32 est formé d'une seule pièce avec son support.In the illustrated example, the buffer 32 is a sleeve fixed on a support 36 itself slidably mounted and free to rotate about the proximal portion 12B of the body 12. The support 36 defines a bearing surface 36B receiving the bearing forces of As a variant, the pad 32 is formed in one piece with its support.

D'une manière générale, le tampon 32 est monté sur la partie proximale 12B du corps 12, mobile en translation le long de l'axe B et de préférence libre en rotation autour de l'axe B. En outre, le tampon 32 est agencé pour être déplacé en translation dans l'orifice 11 par vissage de l'écrou 18.In general, the buffer 32 is mounted on the proximal portion 12B of the body 12, which can be moved in translation along the axis B and preferably free to rotate about the axis B. In addition, the buffer 32 is arranged to be displaced in translation in the orifice 11 by screwing the nut 18.

Pour minimiser les efforts de frottement, l'écrou 18 est muni d'une rondelle 38 d'appui sur le support 36. La rondelle 38 est montée captive et folle sur l'écrou 18.To minimize the friction forces, the nut 18 is provided with a washer 38 bearing on the support 36. The washer 38 is mounted captive and crazy on the nut 18.

Une rondelle supplémentaire 40 optionnelle, de préférence fabriquée dans un matériau à faible coefficient de frottement, est interposée entre la rondelle 38 et l'écrou 18 pour réduire les efforts de frottement.An optional additional washer 40, preferably made of a low friction material, is interposed between the washer 38 and the nut 18 to reduce the frictional forces.

La rondelle supplémentaire 40 est par exemple réalisée en bronze, en polytétrafluoroéthylène ou en acier à faible coefficient de frottement.The additional washer 40 is for example made of bronze, polytetrafluoroethylene or steel with a low coefficient of friction.

Le tampon 32 est, quant à lui, de préférence réalisé dans un matériau dont le coefficient de frottement est relativement élevé. Il est par exemple réalisé dans un matériau élastomère, de préférence en caoutchouc, ou dans un autre matériau de tout type adapté, par exemple en un matériau rigide tel que l'acier.The pad 32 is, for its part, preferably made of a material whose coefficient of friction is relatively high. It is for example made of an elastomeric material, preferably rubber, or another material of any suitable type, for example a rigid material such as steel.

En outre, le matériau utilisé pour le tampon 32 est de préférence déformable élastiquement, comme par exemple le caoutchouc. Mais en variante, le tampon est réalisé dans un matériau rigide et peut également être réalisé dans un matériau à faible coefficient de frottement, par exemple en bronze, tétrafluoroéthylène, en polymère ou en acier.In addition, the material used for the pad 32 is preferably elastically deformable, such as rubber. But alternatively, the pad is made of a rigid material and can also be made of a low friction material, for example bronze, tetrafluoroethylene, polymer or steel.

Le support 36 est quant à lui de préférence réalisé dans un matériau rigide, par exemple en acier.The support 36 is in turn preferably made of a rigid material, for example steel.

L'attache 10 est également remarquable en ce que, une fois l'attache 10 serrée sur la paroi 8, le déplacement du loquet 22 de sa position déployée vers sa position d'insertion desserre l'attache 10 de la paroi 8.The fastener 10 is also remarkable in that, once the fastener 10 is tightened on the wall 8, the displacement of the latch 22 from its extended position towards its insertion position loosens the fastener 10 of the wall 8.

Le loquet 22 est à cet effet articulé rotatif sur le coulisseau 28 entre sa position d'insertion et sa position déployée de telle sorte que le déplacement du loquet 22 de sa position déployée vers sa position d'insertion écarte le loquet 22 de la surface de la paroi 8.The latch 22 is rotatably articulated on the slide 28 between its insertion position and its deployed position so that the displacement of the latch 22 from its deployed position to its insertion position moves the latch 22 away from the surface of the wall 8.

Pour le déplacement automatique du loquet 22 par actionnement de la tige 24, le loquet 22 présente une surface de suiveur de came 42 destinée à coopérer avec une surface de came 42' formée par le corps 12 pour déplacer le loquet 22 de sa position déployée vers et jusqu'à sa position escamotée lors du coulissement de la tige 24 dans un premier sens, à savoir vers l'extrémité proximale 10B de l'attache 10, dans l'exemple illustré.For automatic movement of the latch 22 by actuation of the rod 24, the latch 22 has a cam follower surface 42 for cooperating with a cam surface 42 'formed by the body 12 to move the latch 22 from its deployed position to and to its retracted position during the sliding of the rod 24 in a first direction, namely towards the proximal end 10B of the fastener 10, in the illustrated example.

Inversement, un ensemble came/suiveur de came 44/44' est prévu sur le loquet 22 et le corps 12 pour déplacer le loquet 12 de sa position d'insertion jusqu'à sa position déployée.Conversely, a cam follower / cam follower 44/44 'is provided on the latch 22 and the body 12 to move the latch 12 from its insertion position to its deployed position.

Enfin, l'attache 10 illustrée sur les figures 2 à 4bis est remarquable en ce que les moyens de déplacement de la patte 14 comprennent, outre le coulisseau 28, une bielle 50. La bielle 50 est articulée rotative à l'extrémité distale du coulisseau 28 et à l'extrémité d'un levier 52 solidaire en rotation de la patte 14. Le levier 52 et la patte 14 sont en effet, dans l'exemple illustré, solidarisés en rotation par un méplat 54 formé par l'un et reçu dans l'autre. Le méplat 54 est ici prévu sur la broche d'articulation de la patte 14 sur le corps 12.Finally, the clip 10 illustrated on the Figures 2 to 4bis is remarkable in that the means of displacement of the tab 14 comprise, besides the slide 28, a connecting rod 50. The rod 50 is rotatably articulated at the distal end of the slide 28 and at the end of a lever 52 integral with rotation of the tab 14. The lever 52 and the tab 14 are indeed, in the example shown, secured in rotation by a flat portion 54 formed by one and received in the other. The flat 54 is here provided on the pin of articulation of the lug 14 on the body 12.

La patte 14 présente également, de manière connue, une surface 14A de retenue horizontale de la structure 4, et un crochet 14B d'accrochage d'un levier de la structure 4, pour une retenue verticale.The lug 14 also has, in known manner, a horizontal retaining surface 14A of the structure 4, and a latch hook 14B of a lever of the structure 4, for a vertical retention.

Le fonctionnement de l'attache 10 va maintenant être décrit.The operation of the clip 10 will now be described.

Pour l'insertion de l'attache 10 à travers la paroi 8, l'opérateur tire dans un premier temps la poignée 26, et donc la tige 24 et le coulisseau 28, vers l'extrémité proximale 10B de l'attache 10. Il s'ensuit que la patte 14 et le loquet 22 sont déplacés dans leurs position d'insertion et de retrait respectives, dans lesquelles ces derniers ne font sensiblement pas saillie de façon radiale par rapport au corps 12.For the insertion of the fastener 10 through the wall 8, the operator initially pulls the handle 26, and therefore the rod 24 and the slider 28, towards the proximal end 10B of the fastener 10. As a result, the tab 14 and the latch 22 are moved into their respective insertion and withdrawal positions, in which the latter do not substantially project radially relative to the body 12.

Une fois l'attache 10 insérée à travers l'orifice 11 de la paroi 8, l'opérateur libère la poignée 26.Once the fastener 10 has been inserted through the orifice 11 of the wall 8, the operator releases the handle 26.

Sous l'action du ressort 31, la tige 24 se déplace vers l'extrémité distale de l'attache 10 et déplace, par l'intermédiaire du coulisseau 28, le loquet 22 et la patte 14 vers et jusqu'à leurs positions déployées respectives. Le déplacement de la patte 14 est assuré par la bielle 50 et le déplacement du loquet 22 par les surfaces de came/suiveur de came 44/44'.Under the action of the spring 31, the rod 24 moves towards the distal end of the fastener 10 and moves, through the slider 28, the latch 22 and the tab 14 to and to their respective deployed positions. . Moving from the lug 14 is provided by the rod 50 and the displacement of the latch 22 by the cam surfaces / cam follower 44/44 '.

Une fois cette opération effectuée, l'opérateur visse l'écrou 18 le long du corps 12 pour déplacer le tampon 32 le long du corps 12 de l'attache 10 jusqu'à l'insertion et le serrage du tampon 32 dans l'orifice 11. Le tampon 32 est alors en appui axial et radial dans l'orifice 11.Once this is done, the operator screws the nut 18 along the body 12 to move the buffer 32 along the body 12 of the fastener 10 until the insertion and tightening of the buffer 32 in the orifice 11. The buffer 32 is then axially and radially supported in the orifice 11.

Une fois inséré dans la position de la Figure 4bis, le tampon 32 et le loquet 22 serrent ainsi entre eux la paroi 8 de telle sorte que l'attache 10 est immobilisée axialement dans l'orifice 11.Once inserted into the position of the Figure 4bis , the buffer 32 and the latch 22 thus clamp the wall 8 between them so that the fastener 10 is immobilized axially in the orifice 11.

L'attache 10 est également immobilisée radialement par la portée 34 du tampon 32 et par la portée 29 définie par la partie distale 12A du corps 12.The fastener 10 is also immobilized radially by the bearing surface 34 of the pad 32 and by the bearing surface 29 defined by the distal portion 12A of the body 12.

Enfin, l'attache 10 est immobilisée en rotation autour de l'axe de l'orifice 11 par les efforts de frottement du loquet 22 sur la paroi 8 et du tampon 32 dans l'orifice 11.Finally, the fastener 10 is immobilized in rotation about the axis of the orifice 11 by the frictional forces of the latch 22 on the wall 8 and the buffer 32 in the orifice 11.

Pour retirer l'attache 10, l'opérateur tire la poignée 26, ce qui rabat la patte 14 et dégage le loquet 22 de la paroi 8, desserrant ainsi l'attache 22. Le loquet 22 et la patte 14 sont alors en position d'insertion et il suffit à l'opérateur de tirer l'attache 10 pour la sortir de l'orifice 11. Le dévissage de l'écrou 18 n'est pas nécessaire.To remove the fastener 10, the operator pulls the handle 26, which folds the tab 14 and releases the latch 22 of the wall 8, thereby loosening the fastener 22. The latch 22 and the tab 14 are then in position d insertion and it is sufficient for the operator to pull the clip 10 to remove it from the orifice 11. The unscrewing of the nut 18 is not necessary.

L'attache des figures 2 à 4bis présente ainsi de nombreux avantages.The attachment of Figures 2 to 4bis thus has many advantages.

La portée 34 fournit tout d'abord une surface d'appui importante et uniforme contre la surface interne de l'orifice 11.The bearing surface 34 firstly provides a large and uniform bearing surface against the inner surface of the orifice 11.

Avec l'attache des figures 2 à 4bis, l'immobilisation en rotation du corps 12 autour de son axe, par rapport à la paroi 8, est ainsi fiable même lorsque l'état de surface de la paroi 8 est relativement lisse.With the attachment of Figures 2 to 4bis , immobilization in rotation of the body 12 about its axis, with respect to the wall 8, is thus reliable even when the surface condition of the wall 8 is relatively smooth.

Ensuite, le montage libre en rotation du tampon 32 sur le corps 12 évite des efforts de frottement du tampon dans l'orifice 11 et facilite ainsi le vissage de l'écrou 18.Then, the rotational free mounting of the buffer 32 on the body 12 avoids frictional forces of the buffer in the orifice 11 and thus facilitates the screwing of the nut 18.

Les rondelles 38 et 40 réduisent quant à elles les efforts de frottement lors du vissage de l'écrou 18.The washers 38 and 40 reduce the friction forces during screwing of the nut 18.

Il s'ensuit que pour un même effort de vissage de l'écrou 18, l'effort de serrage obtenu pourra être beaucoup plus important avec l'attache des figures 2 à 4bis, ce qui fiabilise notamment l'immobilisation en rotation, ainsi que les immobilisations en translation axiale et radiale.It follows that for the same screwing effort of the nut 18, the clamping force obtained may be much greater with the attachment of Figures 2 to 4a , which makes reliable immobilization in rotation, as well as fixed assets in axial and radial translation.

Enfin, le montage du loquet 22 permet un retrait rapide et simple.Finally, the mounting of the latch 22 allows quick and easy removal.

Les Figures 5 et 5bis illustrent un mode de réalisation de l'invention dans lequel seules les différences par rapport à l'attache des figures 2 à 4bis sont décrites ci-dessous, et sur lesquelles des numéros de référence identiques aux figures précédentes désignent des éléments analogues.The Figures 5 and 5a illustrate an embodiment of the invention in which only the differences with respect to the attachment of the Figures 2 to 4bis are described below, and on which reference numerals identical to the preceding figures designate similar elements.

L'attache 10 selon les figures 5 et 5bis diffère essentiellement de l'attache 10 selon les figures 2 à 4bis par les moyens de déplacement du loquet 22 et de la patte 14.The fastener 10 according to the figures 5 and 5a differs essentially from the fastener 10 according to the Figures 2 to 4bis by the means for moving the latch 22 and the tab 14.

En effet, les moyens de déplacement de ces derniers comprennent une bielle respective 60, 62 dont une extrémité est articulée rotative sur l'organe à déployer correspondant 14, 22 et dont l'autre extrémité est articulée rotative sur le coulisseau 28.Indeed, the means of displacement of the latter comprise a respective connecting rod 60, 62, one end of which is articulated rotatively on the corresponding deploying member 14, 22 and whose other end is rotatably articulated on the slide 28.

Le tampon 32 a en outre été remplacé par une rondelle 60 délimitant une portée 60A d'immobilisation radiale du corps 12 dans l'orifice 11. La rondelle 60 est solidaire en translation de l'écrou 18.The buffer 32 has also been replaced by a washer 60 delimiting a bearing surface 60A of radial immobilization of the body 12 in the orifice 11. The washer 60 is integral in translation with the nut 18.

Le serrage de l'attache 10 est réalisé par appui axial de la rondelle 38 solidaire de l'écrou 18 sur la face intérieure 6B de la paroi 8, à l'extérieur de l'orifice 11, de manière connue.Clamping of the fastener 10 is achieved by axial support of the washer 38 integral with the nut 18 on the inner face 6B of the wall 8, outside the orifice 11, in a known manner.

En outre, l'attache 12 présente la particularité d'être pourvue d'un écrou 70 de manoeuvre de la tige 24. L'écrou 70 est vissé sur la tige 24 le long de l'axe B au niveau de l'extrémité proximale 24B de la tige 24.In addition, the fastener 12 has the particularity of being provided with a nut 70 for actuating the rod 24. The nut 70 is screwed onto the rod 24 along the axis B at the proximal end. 24B of the stem 24.

L'écrou 70 porte sur le corps 12 de telle sorte que le vissage de l'écrou 70 déplace la tige 24 en translation par rapport au corps 12 le long de l'axe A. Les verrouillages du loquet 22 et de la patte 14 s'en trouvent sécurisés.The nut 70 carries on the body 12 so that the screwing of the nut 70 moves the rod 24 in translation relative to the body 12 along the axis A. The latches of the latch 22 and the tab 14 s 'find it secure.

A noter également que la position proximale 12B du corps 12 est désaxée radialement par rapport à la position distale 12A.It should also be noted that the proximal position 12B of the body 12 is offset radially relative to the distal position 12A.

Pour l'actionnement de l'attache 12, l'écrou 70 est d'abord dévissé le long de la tige 24, de façon à pouvoir pousser cette dernière dans le corps 12 et à déplacer ainsi le loquet 22 et la patte 14 dans leur position d'insertion illustrée sur la Figure 5. Dans cette position, la patte 14 se trouve sensiblement dans le prolongement du corps 12.For the actuation of the fastener 12, the nut 70 is first unscrewed along the rod 24, so as to push the latter into the body 12 and thus move the latch 22 and the lug 14 in their housing. insertion position illustrated on the Figure 5 . In this position, the tab 14 is substantially in the extension of the body 12.

Une fois l'attache dans sa position de la Figure 5, l'opérateur visse dans un premier temps l'écrou 70 pour déplacer la tige 24 vers l'extrémité proximale 10B de l'attache 10 et déplacer ainsi le loquet 22 et la patte 14 vers leur position déployée par l'intermédiaire des bielles 60 et 62.Once the fastener in its position of the Figure 5 , the operator first screws the nut 70 to move the rod 24 towards the proximal end 10B of the fastener 10 and thus move the latch 22 and the tab 14 to their deployed position via the connecting rods 60 and 62.

Les bielles 60 et 62 ont l'avantage de permettre un bras de levier important sur les organes déployables 14, 22. En outre, les bielles 60 et 62 sont coudées, pour un encombrement réduit.The rods 60 and 62 have the advantage of allowing a large lever arm on the deployable members 14, 22. In addition, the rods 60 and 62 are bent, for a small footprint.

Enfin, la bielle 60 permet d'allonger le loquet 22, et d'améliorer ainsi le serrage de l'attache 10 sur la paroi 8.Finally, the connecting rod 60 makes it possible to lengthen the latch 22, and thus to improve the tightening of the fastener 10 on the wall 8.

L'écrou 70 de retenue de la tige 24 sécurise l'attache 10 en empêchant, une fois vissé, le déplacement du loquet 22 et de la tige 14 vers leur position d'insertion.The nut 70 retaining the rod 24 secures the fastener 10 by preventing, once screwed, the displacement of the latch 22 and the rod 14 to their insertion position.

Le désaxage de la partie proximale 12B du corps 12 par rapport à la partie distale 12A du corps 12 permet de réduire l'encombrement du coulisseau 28 dans la partie distale 12A du corps 12 et ainsi un grand dimensionnement des organes déployables 14, 22.The misalignment of the proximal portion 12B of the body 12 relative to the distal portion 12A of the body 12 reduces the bulk of the slider 28 in the distal portion 12A of the body 12 and thus a large dimensioning of the deployable members 14, 22.

Il est à noter que les caractéristiques propres aux différentes attaches décrites ci-dessus peuvent être combinées entre elles suivant toutes les combinaisons techniquement possibles. Le tampon 32 peut par exemple être prévu sur l'attache des figures 5 et 5bis. De même, les moyens de déplacement du loquet 22 et de la patte 14 des figures 2 à 4bis peuvent être utilisés dans l'attache des figures 5 et 5bis.It should be noted that the characteristics of the different fasteners described above can be combined with each other in any technically possible combination. The buffer 32 may for example be provided on the fastener of the figures 5 and 5a . Similarly, the means for moving the latch 22 and the tab 14 of the Figures 2 to 4bis can be used in attaching figures 5 and 5a .

Enfin, à noter qu'avantageusement, le loquet 22 peut être prévu de couleur rouge de son côté interne de façon à ce qu'un opérateur puisse facilement vérifier son déploiement depuis le sol.Finally, note that advantageously, the latch 22 may be provided with a red color on its internal side so that an operator can easily check its deployment from the ground.
