Description

La présente invention concerne les sangles de traction adaptables sur un outil à main tel qu'un piolet muni d'un manche dont une extrémité libre forme zone de préhension et dont l'extrémité opposée se raccorde à une tête d'outil. La sangle est pourvue de moyens d'accrochage au manche au voisinage de la tête d'outil. La sangle forme une boucle au voisinage de la zone de préhension pour permettre le passage et le maintien du poignet d'une main de l'utilisateur tenant l'outil par ladite zone de préhension.The present invention relates to traction straps adaptable to a hand tool such as an ice ax equipped with a handle, one free end of which forms a gripping zone and the opposite end of which is connected to a tool head. The strap is provided with means for hooking to the handle in the vicinity of the tool head. The strap forms a loop in the vicinity of the gripping area to allow the passage and maintenance of the wrist with one hand of the user holding the tool by said gripping area.

Dans les techniques actuelles de l'alpinisme, on utilise fréquemment des piolets techniques en traction. Le piolet, tel que décrit par exemple dans le document FR-A-2 145 124, comporte une tête d'outil munie d'une lame s'étendant selon une direction généralement transversale par rapport à l'axe du manche. L'utilisateur, par un mouvement de frappe, plante la lame de tête d'outil dans la paroi de glace qu'il veut gravir, le manche se développant vers l'aval. L'utilisateur peut alors se tirer sur le manche pour se déplacer vers l'amont. Il dégage ensuite la lame de tête d'outil hors de la paroi de glace, et la replante plus haut pour recommencer le mouvement de traction.In current mountaineering techniques, technical ice axes are frequently used in traction. The ice ax, as described for example in document FR-A-2 145 124, comprises a tool head provided with a blade extending in a generally transverse direction relative to the axis of the handle. The user, by a striking movement, plants the tool head blade in the wall of ice that he wants to climb, the handle developing downstream. The user can then pull on the handle to move upstream. He then releases the tool head blade from the glass wall, and replants it higher to start the traction movement again.

La traction peut naturellement être supportée par la main, entourant la partie de préhension du manche. Cependant, des sangles ont été prévues dans certains piolets connus, comme dans d'autres outils d'alpinisme tels que décrits dans le document FR-A-2 134 953, pour entourer le poignet de la main passée autour du manche, la sangle étant susceptible de supporter tout ou partie de l'effort de tenue de l'outil, pour soulager la main.The traction can naturally be supported by the hand, surrounding the grip part of the handle. However, straps have been provided in certain known ice axes, as in other mountaineering tools as described in document FR-A-2 134 953, to surround the wrist with the hand passed around the handle, the strap being likely to support all or part of the tool holding effort, to relieve the hand.

Dans ces piolets connus à sangle de traction, la sangle forme une boucle entourant le poignet, cette boucle devant être serrée lorsque le poignet est en position de traction avec la main passée autour de la partie de préhension du manche. L'utilisateur doit donc adapter la longueur de boucle de sangle à la dimension de circonférence du poignet. Une première manoeuvre est nécessaire pour régler cette longueur et mettre la sangle en position de traction. Une seconde manoeuvre est nécessaire lorsque l'utilisateur veut dégager entièrement sa main hors de la sangle. Dans les piolets connus, on prévoit pour cela des moyens traditionnels de réglage de longueur de sangle, dont la manoeuvre nécessite l'intervention de l'autre main de l'utilisateur ou de ses dents.In these known axes with traction strap, the strap forms a loop surrounding the wrist, this loop having to be tightened when the wrist is in the traction position with the hand passed around the grip part of the handle. The user must therefore adapt the length of the strap buckle to the circumference dimension of the wrist. A first maneuver is necessary to adjust this length and put the strap in the pulling position. A second maneuver is necessary when the user wants to completely release his hand from the strap. In known ice axes, provision is made for this for traditional means of adjusting the length of the strap, the operation of which requires the intervention of the other hand of the user or of his teeth.

La nécessité d'intervention de l'autre main de l'utilisateur ou de ses dents constitue un inconvénient que la présente invention vise à éliminer.The need to intervene with the other hand of the user or his teeth constitutes a drawback that the present invention aims to eliminate.

Ainsi, le problème proposé par la présente invention est de concevoir une nouvelle structure de sangle de traction pour outil à main tel qu'un piolet dans laquelle l'adaptation et le serrage de la sangle autour du poignet en position de traction peut se faire par mouvement de la seule main dont le poignet et passé dans la sangle, et dans laquelle le dégagement total de la main hors de la sangle peut se faire également par le déplacement de la seule main dont le poignet et passé dans la sangle, sans jamais nécessiter l'intervention de l'autre main de l'utilisateur ou de ses dents. Simultanément, en position de traction, la sangle, passant autour du poignet, ne doit pas présenter un effet de noeud coulant tendant à serrer exagérément le poignet. La sangle doit juste serrer le poignet pour qu'il ne puisse pas en sortir, et pour éviter ainsi la perte de l'outil.Thus, the problem proposed by the present invention is to design a new traction strap structure for a hand tool such as an ice ax in which the adaptation and tightening of the strap around the wrist in the traction position can be done by movement of the single hand including the wrist and passed through the strap, and in which the complete release of the hand out of the strap can also be done by the movement of the single hand including the wrist and passed through the strap, without ever requiring the intervention of the other hand of the user or his teeth. Simultaneously, in the pulling position, the strap, passing around the wrist, must not have a noose effect tending to tighten the wrist excessively. The strap should just tighten the wrist so that it cannot come out, and thus avoid the loss of the tool.

Ainsi, les fonctions essentielles d'une sangle de traction selon la présente invention sont les suivantes :

  • - la sangle doit pouvoir tenir serré un poignet en une position fermée dans laquelle la main correspondante est sur l'extrémité de préhension du manche ; dans cette position fermée, une traction longitudinale à l'écart de la tête d'outil peut être supportée par la sangle retenant le poignet ;
  • - la sangle doit se desserrer et libérer à volonté le poignet sans intervention de l'autre main ou des dents de l'utilisateur, par un mouvement de traction du poignet engagé dans la sangle, ce mouvement s'effectuant à l'écart du manche dans une direction non parallèle au manche et non dirigée à l'opposé de la tête d'outil ;
  • - mise en position ouverte, la sangle doit rester dans cette position ouverte et permettre le passage du poignet,
  • - la sangle doit pouvoir se refermer sur le poignet par simple passage du poignet et traction sur la sangle par le poignet dans une direction parallèle au manche et à l'écart de la tête d'outil.
Thus, the essential functions of a traction strap according to the present invention are the following:
  • - the strap must be able to hold a wrist tight in a closed position in which the corresponding hand is on the grip end of the handle; in this closed position, a longitudinal pull away from the tool head can be supported by the strap retaining the wrist;
  • - the strap must loosen and free the wrist at will without intervention of the other hand or the user's teeth, by a pulling movement of the wrist engaged in the strap, this movement being carried out away from the handle in a direction not parallel to the handle and not directed opposite the tool head;
  • - put in the open position, the strap must remain in this open position and allow the wrist to pass,
  • - the strap must be able to close on the wrist by simply passing the wrist and pulling the strap by the wrist in a direction parallel to the handle and away from the tool head.

De préférence, la sangle doit être réglable pour s'adapter aux longueurs courantes de piolets.Preferably, the strap should be adjustable to accommodate common ice ax lengths.

Pour atteindre ces objets ainsi que d'autres, la présente invention prévoit une sangle de traction adaptable sur un outil à main tel qu'un piolet muni d'un manche avec une zone de préhension au voisinage d'une extrémité libre, l'extrémité opposée du manche se raccordant à une tête d'outil par une zone de jonction, la sangle étant pourvue de moyens d'accrochage à la tête d'outil, la sangle formant une boucle de maintien au voisinage de la zone de préhension pour le passage et le maintien d'un poignet de l'utilisateur tenant ladite zone de préhension. La sangle selon l'invention est telle que :

  • - entre les moyens d'accrochage et la boucle de maintien, la sangle est formée d'un premier et d'un second brins généralement parallèles l'un à l'autre,
  • - les premières extrémités des deux brins sont solidarisées par les moyens d'accrochage,
  • - les secondes extrémités opposées des deux brins sont solidaires l'une de l'autre en continuité pour former la boucle de maintien,
  • - les deux brins passent simultanément dans un même passant, le premier brin coulissant librement dans ledit passant,
  • - le passant est solidarisé au second brin par des moyens de solidarisation, à la base de la boucle de maintien,
  • - un moyen de maintien assure la liaison entre une zone intermédiaire du second brin, zone intermédiaire située entre la première extrémité et le passant, et une zone intermédiaire choisie du manche d'outil.
To achieve these and other objects, the present invention provides a traction strap adaptable to a hand tool such as an ice ax provided with a handle with a gripping area in the vicinity of a free end, the end opposite of the handle connecting to a tool head by a junction zone, the strap being provided with means for hooking to the tool head, the strap forming a holding loop in the vicinity of the grip zone for passage and maintaining a wrist of the user holding said gripping area. The strap according to the invention is such that:
  • - between the attachment means and the retaining loop, the strap is formed of first and second strands generally parallel to each other,
  • - the first ends of the two strands are secured by the attachment means,
  • the second opposite ends of the two strands are integral with one another in continuity to form the holding loop,
  • - the two strands pass simultaneously in the same pass, the first free sliding strand lying in said passerby,
  • - the passer-by is secured to the second strand by means of attachment, at the base of the retaining loop,
  • - A holding means provides the connection between an intermediate zone of the second strand, intermediate zone located between the first end and the passer-by, and a chosen intermediate zone of the tool handle.

De préférence, la longueur de sangle est réglable, pour s'adapter à la longueur de la partie de manche d'outil située entre la tête d'outil et la zone de préhension.Preferably, the strap length is adjustable, to adapt to the length of the tool handle portion located between the tool head and the gripping area.

D'autres objets, caractéristiques et avantages de la présente invention ressortiront de la description suivante de modes de réalisation particuliers, faite en relation avec les figures jointes, parmi lesquelles :

  • - la figure 1 est une vue générale d'une sangle selon la présente invention ;
  • - la figure 2 est une vue de côté d'un piolet technique muni d'une sangle selon la présente invention en position de traction ;
  • - la figure 3 est une vue de côté du même piolet avec la même sangle selon la présente invention en position intermédiaire pendant un mouvement d'ouverture pour libérer le poignet ; et
  • - la figure 4 représente le piolet avec la sangle en position ouverte.
Other objects, characteristics and advantages of the present invention will emerge from the following description of particular embodiments, given in relation to the attached figures, among which:
  • - Figure 1 is a general view of a strap according to the present invention;
  • - Figure 2 is a side view of a technical ice ax provided with a strap according to the present invention in the traction position;
  • - Figure 3 is a side view of the same ice ax with the same strap according to the present invention in the intermediate position during an opening movement to release the wrist; and
  • - Figure 4 shows the ice ax with the strap in the open position.

Dans le mode de réalisation représenté sur la figure 2, l'outil à main recevant une sangle selon l'invention est un piolet technique muni d'un manche 1 avec une zone de préhension 2 au voisinage de son extrémité libre 3. L'extrémité opposée 4 du manche se raccorde à une tête d'outil 5 par une zone de jonction 6. La tête d'outil 5 comprend notamment une lame 7 destinée à être plantée dans une paroi de glace 8, le manche 1 se développant alors vers l'aval comme le représente la figure 2.In the embodiment shown in FIG. 2, the hand tool receiving a strap according to the invention is a technical ice ax provided with a handle 1 with a grip zone 2 in the vicinity of its free end 3. The end opposite 4 of the handle is connected to a tool head 5 by a junction zone 6. The tool head 5 comprises in particular a blade 7 intended to be planted in an ice wall 8, the handle 1 then developing towards the 'downstream as shown in Figure 2.

La sangle 9 selon l'invention est pourvue, à une première extrémité, de moyens d'accrochages 10 pour son accrochage à la tête d'outil 5. A sa seconde extrémité, la sangle 9 forme une boucle de maintien 13 conformée pour entourer le poignet d'un utilisateur.The strap 9 according to the invention is provided, at a first end, with hooking means 10 for its attachment to the tool head 5. At its second end, the strap 9 forms a holding loop 13 shaped to surround the wrist of a user.

Entre les moyens d'accrochage 10 et la boucle de maintien 13, la sangle 9 est formée d'un premier brin 11 et d'un second brin 12 généralement parallèles l'un à l'autre. Les premières extrémités 14 et 15 des deux brins sont solidarisées par les moyens d'accrochage 10. En pratique, ces premières extrémités de brins 11 et 12 sont solidarisées par une couture 33 transversale.Between the attachment means 10 and the retaining loop 13, the strap 9 is formed of a first strand 11 and a second strand 12 generally parallel to one another. The first ends 14 and 15 of the two strands are secured by the hooking means 10. In practice, these first ends of strands 11 and 12 are secured by a transverse seam 33.

Les secondes extrémités opposées des deux brins 11 et 12 sont solidaires l'une de l'autre en continuité pour former la boucle de maintien 13, comme le représentent les figures.The second opposite ends of the two strands 11 and 12 are integral with one another in continuity to form the retaining loop 13, as shown in the figures.

Les deux brins 11 et 12 passent simultanément dans un même passant 16. Le premier brin 11 coulisse librement dans le passant 16. Par contre, le passant 16 est solidarisé au second brin 12 par des moyens de solidarisation 17, à la base de la boucle de maintien 13. Ainsi, la boucle de maintien 13 est formée par la partie de sangle reliant les deux brins 11 et 12 et sortant du passant 16 à l'opposé des moyens d'accrochage 10.The two strands 11 and 12 pass simultaneously in the same pass 16. The first strand 11 slides freely in the pass 16. On the other hand, the pass 16 is secured to the second strand 12 by means of attachment 17, at the base of the loop holding device 13. Thus, the holding loop 13 is formed by the part of the strap connecting the two strands 11 and 12 and leaving the loop 16 opposite the attachment means 10.

Le second brin 12 coopère en outre avec un moyen de maintien 18, en une zone intermédiaire du second brin 12 entre sa première extrémité 15 et le passant 16. Le moyen de maintien 18 est conformé pour être fixé en une zone intermédiaire choisie du manche 1 d'outil, et pour solidariser ainsi ladite zone intermédiaire de second brin 12 à ladite zone intermédiaire choisie de manche 1 d'outil.The second strand 12 further cooperates with a holding means 18, in an intermediate zone of the second strand 12 between its first end 15 and the loop 16. The holding means 18 is shaped to be fixed in a chosen intermediate zone of the handle 1 of tool, and to thus secure said intermediate zone of second strand 12 to said selected intermediate zone of handle 1 of tool.

Par cette disposition, la boucle de maintien 13 est de longueur réglable par coulissement du premier brin 11 de sangle dans le passant 16. Le coulissement est obtenu automatiquement à l'ouverture et à la fermeture par simple déplacement du poignet de l'utilisateur passé dans la boucle de maintien 13.By this arrangement, the retaining loop 13 is of adjustable length by sliding the first strand 11 of strap in the loop 16. The sliding is obtained automatically on opening and closing by simple movement of the wrist of the user passed in the holding loop 13.

Dans le mode de réalisation représenté, les moyens d'accrochage 10 comprennent des moyens de réglage en longueur, permettant d'adapter la longueur de sangle 9 à la longueur du manche 1 d'outil, pour positionner la boucle de maintien 13 au niveau de la zone de préhension 2 du manche 1 d'outil. Pour cela, les moyens d'accrochage 10 comprennent un prolongement 19 de sangle, prolongeant le second brin 12 au-delà de sa première extrémité 15. Le prolongement 19 est destiné à traverser une lumière 20 prévue dans la tête d'outil 5. Deux anneaux 21 et 22 sont fixés à la première extrémité 14 du premier brin 11 de sangle par une boucle de sangle 23. Après passage dans la lumière 20, on peut coincer de manière connue le prolongement 19 dans les deux anneaux 21 et 22, pour assurer l'accrochage de la sangle 9 à la tête d'outil 5 et son réglage en longueur.In the embodiment shown, the attachment means 10 comprise length adjustment means, making it possible to adapt the length of the strap 9 to the length of the tool handle 1, in order to position the holding loop 13 at the level of the gripping zone 2 of the tool handle 1. For this, the attachment means 10 comprise a strap extension 19, extending the second strand 12 beyond its first end 15. The extension 19 is intended to pass through a lumen 20 provided in the tool head 5. Two rings 21 and 22 are fixed to the first end 14 of the first strap strand 11 by a strap loop 23. After passing through the opening 20, the extension 19 can be wedged in known manner in the two rings 21 and 22, to ensure the attachment of the strap 9 to the tool head 5 and its length adjustment.

Dans le mode de réalisation représenté sur les figures, le moyen de solidarisation 17 du passant 16 comprend une tirette 24 solidaire du passant 16 et pourvue d'une face d'accrochage coopérant avec une face correspondante du second brin 12 de sangle. Les deux faces d'accrochage constituent une zone d'accrochage 25 amovible de type tissu à crochet-tissu à bouclettes. On peut ainsi régler, par déplacement de la tirette 24 sur le second brin 12, la circonférence de boucle de maintien 13 pour l'adapter à la circonférence du poignet de l'utilisateur.In the embodiment shown in the figures, the fastening means 17 of the loop 16 comprises a pull tab 24 secured to the loop 16 and provided with a hooking face cooperating with a corresponding face of the second strand 12 of strap. The two hooking faces constitute a removable hooking zone 25 of the hook-fabric-loop fabric type. It is thus possible, by displacement of the pull tab 24 on the second strand 12, the circumference of the holding loop 13 to adapt it to the circumference of the wrist of the user.

Dans le mode de réalisation représenté, le moyen de maintien 18 peut avantageusement être une languette de maintien solidarisée transversalement sur le second brin 12, et conformée pour entourer et serrer le manche 1 d'outil. Les deux extrémités de la languette de maintien sont conformées pour s'accrocher l'une sur l'autre de manière amovible, en prévoyant par exemple des faces de type tissu à crochet- tissu à bouclettes.In the embodiment shown, the holding means 18 can advantageously be a holding tongue secured transversely to the second strand 12, and shaped to surround and tighten the tool handle 1. The two ends of the retaining tab are shaped to hang one on the other in a removable manner, by providing, for example, faces of the hook fabric-loop fabric type.

En alternative, le moyen de maintien 18 peut comprendre un trou ménagé dans la partie intermédiaire appropriée du manche 1 d'outil, trou traversé par le second brin 12 de sangle. La fonction de liaison entre la zone intermédiaire de second brin 12 et la zone intermédiaire de manche 1 d'outil est ainsi assurée de manière équivalente.Alternatively, the holding means 18 may include a hole made in the appropriate intermediate part of the tool handle 1, hole through which the second strap strand 12 passes. The link function between the second strand intermediate zone 12 and the intermediate handle region 1 of the tool is thus provided in an equivalent manner.

Le premier brin 11 comprend avantageusement, au voisinage de sa première extrémité 14, une surépaisseur 26 constituant un frein pour s'opposer au coulissement du premier brin 11 dans le passant 16 lorsque la sangle est en position ouverte. La surépaisseur peut être simplement constituée par le retour de sangle après la boucle 23, solidarisé au premier brin 11 par des coutures.The first strand 11 advantageously comprises, in the vicinity of its first end 14, an extra thickness 26 constituting a brake to oppose the sliding of the first strand 11 in the loop 16 when the strap is in the open position. The additional thickness may simply consist of the strap return after the loop 23, secured to the first strand 11 by seams.

La boucle de maintien 13 peut avantageusement être munie d'une boucle secondaire 28 d'auto- assurance, comme représenté sur les figures. La boucle d'auto-assurance 28 est conformée pour permettre le passage d'un mousqueton.The holding loop 13 can advantageously be provided with a secondary self-insurance loop 28, as shown in the figures. The self-insurance loop 28 is shaped to allow the passage of a carabiner.

La boucle de maintien 13 est avantageusement munie d'un renfort 27, augmentant la surface portante de la sangle dans cette zone de maintien, pour augmenter le confort de l'utilisateur.The holding loop 13 is advantageously provided with a reinforcement 27, increasing the carrying surface of the strap in this holding zone, to increase the comfort of the user.

Le fonctionnement de la sangle 9 selon l'invention est le suivant : la sangle est représentée sur la figure 4 en position ouverte, position dans laquelle la boucle de maintien 13 a une circonférence qui excède sensiblement la circonférence d'un poignet d'utilisateur. Dans cette position, l'utilisateur peut donc passer aisément sa main à travers la boucle de maintien 13.The operation of the strap 9 according to the invention is as follows: the strap is shown in FIG. 4 in the open position, position in which the retaining loop 13 has a circumference which substantially exceeds the circumference of a user's wrist. In this position, the user can therefore easily pass his hand through the holding loop 13.

L'utilisateur exerce alors une traction de la sangle 9 vers la zone de préhension 2 de l'outil, par une simple traction de son poignet dans la direction appropriée, pour ramener la sangle 9 dans la position de traction représentée sur la figure 2, position dans laquelle la boucle de maintien 13 se trouve à proximité de la zone de préhension 2. Dans cette position, une traction du poignet exercée sur la boucle de maintien 13 parallèlement au manche 1 à l'écart de la tête d'outil 5, comme le représente la flèche 30, produit un coulissement du passant 16 sur le premier brin 11 de sangle, produisant le resserrement de la boucle de maintien jusqu'à ce que les portions de premier brin 11 et de second brin 12 situés entre le passant et les moyens d'accrochage 10 aient la même longueur. Le reserrement de la boucle de maintien est alors limité. La sangle est alors en position de traction, ses deux brins 11 et 12 étant tendus entre les moyens d'accrochage 10 et la boucle de maintien 13, la boucle de maintien 13 étant adaptée étroitement autour du poignet de l'utilisateur dont la main tient simultanément la zone de préhension 2 de l'outil, la circonférence de la boucle de maintien 13 étant déterminée par la position choisie de la tirette 24 de solidarisation du passant 16 sur le second brin 12.The user then pulls the strap 9 towards the grip zone 2 of the tool, by simply pulling his wrist in the appropriate direction, to bring the strap 9 back to the pulling position shown in FIG. 2, position in which the holding loop 13 is located near the gripping area 2. In this position, a wrist pull exerted on the holding loop 13 parallel to the handle 1 away from the tool head 5, as shown by arrow 30, produces a sliding of the loop 16 on the first strand 11 of strap, producing the tightening of the retaining loop until the portions of first strand 11 and second strand 12 located between the loop and the attachment means 10 have the same length. The tightening of the holding loop is then limited. The strap is then in the pulling position, its two strands 11 and 12 being stretched between the hooking means 10 and the holding loop 13, the holding loop 13 being fitted tightly around the wrist of the user whose hand is holding simultaneously the gripping zone 2 of the tool, the circumference of the retaining loop 13 being determined by the chosen position of the pull tab 24 for securing the loop 16 to the second strand 12.

Pour dégager sa main hors de la sangle 9, l'utilisateur peut simplement exercer un mouvement de traction du poignet engagé dans la boucle de maintien 13, la traction s'effectuant à l'écart du manche 1 dans une direction non parallèle au manche 1 et non dirigée à l'opposé de la tête d'outil 5. En pratique, une telle traction peut s'effectuer par mouvement de rotation illustré par la figure 3 selon la flèche 31. Par ce mouvement, le passant 16 est retenu par le second brin 12, à distance constante de la languette de maintien 18, tandis que l'ensemble de la boucle de maintien se rapproche du moyen d'accrochage 10. Le premier brin 11 est alors détendu, de sorte qu'une traction du poignet sur la boucle de maintien 13 provoque le coulissement du premier brin 11 dans le passant 16 comme le représente la flèche 32, ce qui augmente la circonférence de boucle de maintien 13 et autorise le dégagement de la main hors de la boucle de maintien 13.To release his hand from the strap 9, the user can simply exert a pulling movement of the wrist engaged in the holding loop 13, the pulling being carried out away from the handle 1 in a direction not parallel to the handle 1 and not directed opposite the tool head 5. In practice, such traction can be effected by rotational movement illustrated in FIG. 3 according to arrow 31. By this movement, the passer-by 16 is retained by the second strand 12, at constant distance from the holding tab 18, while the whole of the holding loop approaches the hooking means 10. The first strand 11 is then relaxed, so that a pull of the wrist on the retaining loop 13 causes the first strand 11 to slide in the loop 16 as shown by arrow 32, which increases the circumference of retaining loop 13 and allows the hand to be released from the retaining loop 13.

Pendant le mouvement d'ouverture, l'utilisateur peut interrompre le mouvement en position intermédiaire, la sangle restant alors en position ouverte représentée sur la figure 4.During the opening movement, the user can interrupt the movement in the intermediate position, the strap then remaining in the open position shown in FIG. 4.

En poursuivant le mouvement de rotation selon la flèche 31 de la figure 3, le premier brin 11 coulisse dans le passant 16, et peut coulisser avantageusement jusqu'à une position de pleine ouverture dans laquelle le passant atteint la zone de première extrémité du premier brin 11, zone occupée par la surépaisseur 26. Si l'utilisateur relâche la sangle 9 dans cette position de pleine ouverture, le passant 16 est freiné par la surépaisseur 26, de sorte que la boucle de maintien 13 reste plus sûrement en position ouverte, dans laquelle son diamètre est très supérieur à celui du poignet de l'utilisateur.By continuing the rotational movement according to arrow 31 in FIG. 3, the first strand 11 slides in the loop 16, and can advantageously slide to a fully open position in which the loop reaches the region of the first end of the first strand 11, zone occupied by the extra thickness 26. If the user releases the strap 9 in this fully open position, the passer-by 16 is braked by the extra thickness 26, so that the retaining loop 13 remains more securely in the open position, in which is much larger in diameter than the user's wrist.

Ainsi, pour une utilisation ultérieure, l'utilisateur peut très facilement repasser sa main dans la boucle de maintien 13, qui a conservé une circonférence très supérieure à celle du poignet.Thus, for later use, the user can very easily iron his hand in the holding loop 13, which has retained a circumference much greater than that of the wrist.

Les brins 11 et 12 peuvent être réalisés par une cordelette, une sangle, un câble ou toute autre forme de lien. Par contre, la boucle de maintien 13 peut avantageusement être réalisée en une matière et selon une forme appropriées pour recevoir le poignet et former une surface d'appui suffisante. Ainsi, la boucle de maintien 13 peut avoir une forme de sangle de largeur plus importante, augmentant le confort de l'utilisateur.The strands 11 and 12 can be produced by a cord, a strap, a cable or any other form of link. On the other hand, the retaining loop 13 can advantageously be made of a material and in a shape suitable for receiving the wrist and forming a sufficient bearing surface. Thus, the retaining loop 13 can have a form of strap of greater width, increasing the comfort of the user.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
