Abstract

The woven strap comprises at least two continuous parts having different widths, wherein the change in width results from a modification of the respective weave of said parts. The strap can thus be used to create a loop or a ring in order to attach or bear a load. The two ends of the strap (10) are joined to each other by stitching. Only the stitching areas of each of the two ends are tubular. The rest of the ring is flat and the stitching areas are placed on top of each other. The loop or ring can include an integrated wear and tear and/or overload indicator.

Description

SANGLE TISSEE A LARGEUR VARIABLE. ET PRODUITS METTANT EN ŒUVRE UNE TELLE SANGLEWOVEN STRAP WITH VARIABLE WIDTH. AND PRODUCTS IMPLEMENTING SUCH A STRAP
DOMAINE TECHNIQUE L'invention concerne de manière fondamentale une sangle obtenue par tissage, dont la caractéristique première réside dans le fait qu'elle présente des zones de largeurs variables.TECHNICAL FIELD The invention relates fundamentally to a strap obtained by weaving, the primary characteristic of which resides in the fact that it has zones of variable widths.
Dans la suite de la description, outre dans les revendications, le terme « largeur » désigne la plus petite dimension de la sangle dans le plan général dans lequel elle s'inscrit. Le terme sangle doit lui-même être interprétée selon son acception première à savoir une bande plate. Ce faisant, il convient bien de distinguer au sens de l'invention, la largeur de la sangle de son épaisseur, constituée par sa dimension selon une direction perpendiculaire au plan contenant la sangle.In the remainder of the description, in addition to the claims, the term “width” designates the smallest dimension of the strap in the general plane in which it is inscribed. The term strap must itself be interpreted according to its primary meaning, namely a flat band. In doing so, it is advisable to distinguish within the meaning of the invention, the width of the strap from its thickness, constituted by its dimension in a direction perpendicular to the plane containing the strap.
L'invention concerne également les produits susceptibles de mettre en œuvre une telle sangle. Elle vise ainsi tout d'abord une boucle ou anneau, et de manière générale toute structure fermée sur elle-même, réalisé à partir de cette sangle tissée et plus particulièrement destinée au domaine de la montagne et de l'escalade, de la sécurité et du levage, mais également de manière plus générale, à tous les domaines mettant en œuvre une charge.The invention also relates to the products capable of implementing such a strap. It thus firstly targets a loop or ring, and in general any structure closed on itself, produced from this woven strap and more particularly intended for the field of mountain and climbing, safety and lifting, but also more generally, to all areas involving a load.
Elle vise également les laisses pour animaux, les sangles d'instruments de musique, les bracelets, purement décoratifs ou bracelets-montre, les anses de sac, etc.It also covers leashes for animals, straps for musical instruments, bracelets, purely decorative or watch bracelets, bag handles, etc.
ETAT ANTERIEUR DE LA TECHNIQUE Dans le cadre plus spécifique de l'escalade, les adeptes de celle-ci utilisent dans des situations particulières mais répétées des anneaux réalisés à partir d'une sangle, en général tissée. Cet anneau est par exemple solidarisé au baudrier porté par l'utilisateur et en outre dans un mousqueton fixé dans un point d'ancrage approprié. Cet anneau peut également servir comme élément de prise d'appui pour les genoux ou les pieds de l'utilisateur.PRIOR STATE OF THE ART In the more specific context of climbing, the followers of this use in particular but repeated situations rings made from a strap, generally woven. This ring is for example secured to the harness worn by the user and also in a carabiner fixed in an appropriate anchor point. This ring can also serve as a support element for the knees or feet of the user.
De manière connue, de tels anneaux doivent allier à la fois résistance mécanique et légèreté. En outre, ils doivent répondre, à tout le moins pour certains d'entre eux, à des normes, telles que notamment la norme NF EN 566 « Anneau » d'Avril 1997. Celle-ci précise que pour un anneau de sangle de 9 millimètres de large, la résistance mécanique doit être supérieure ou égale à 2.200 DaN. Afin de réaliser un tel anneau, on a proposé, par exemple dans le documentIn known manner, such rings must combine both mechanical strength and lightness. In addition, they must meet, at least for some of them, standards, such as in particular standard NF EN 566 "Ring" of April 1997. This specifies that for a strap ring of 9 millimeters wide, the mechanical resistance must be greater than or equal to 2,200 DaN. In order to produce such a ring, it has been proposed, for example in the document
WO03/059462, la mise en oeuvre d'une boucle constituée d'un tissu ou maillage tubulaire pourvu de deux extrémités, ces deux extrémités étant solidarisées l'une à l'autre en un point de connexion par introduction de l'une des deux extrémités dans l'autre extrémité, et par couture desdites extrémités au niveau de ce point de connexion.WO03 / 059462, the implementation of a loop consisting of a tubular fabric or mesh provided with two ends, these two ends being secured to one another at a connection point by introduction of one of the two ends in the other end, and by sewing said ends at this connection point.
Si, sur le plan mécanique, une telle boucle ou un tel anneau est susceptible de répondre aux exigences prescrites, et éventuellement à celles de la norme rappelée ci- dessus, en revanche, il elle présente les inconvénients suivants : " tout d'abord, le coût de réalisation d'une telle boucle est grevé par la main d'œuvre nécessaire à sa réalisation, dans la mesure où il est nécessaire d'enfiler l'une des extrémités du matériau constitutif dans l'autre, opération qui ne peut être faite que manuellement, et qui demande en outre une certaine dextérité ; " ensuite, le matériau constitutif est traditionnellement réalisé sur des métiers à tisser d'un type en soi connu, et la bande en résultant est sectionnée à intervalles réguliers correspondants à la longueur souhaitée de la boucle ; cette découpe est généralement réalisée au moyen d'une lame chaude, qui induit outre la découpe, également la soudure du tissu ou maillage tubulaire, qu'il importe donc de réouvrir, afin de permettre l'introduction de l'une de ses extrémités dans l'autre, constituant là encore une opération consommatrice de temps.If, mechanically, such a loop or such a ring is capable of meeting the prescribed requirements, and possibly those of the standard recalled above, on the other hand, it has the following drawbacks: "first of all, the cost of making such a loop is burdened by the labor required to make it, insofar as it is necessary to thread one end of the constituent material into the other, an operation which cannot be made only manually, and which also requires a certain dexterity; "then, the constituent material is traditionally produced on weaving looms of a type known per se, and the resulting strip is cut at regular intervals corresponding to the desired length of the loop; this cutting is generally carried out by means of a hot blade, which induces in addition to the cutting, also the welding of the fabric or tubular mesh, which it is therefore important to reopen, in order to allow the introduction of one of its ends into the other, again constituting a time consuming operation.
Dans le domaine plus général des sangles, et notamment dans le cadre des laisses pour animaux et autres anses de préhension de sacs et cabas, l'utilisateur souhaite le plus souvent bénéficier d'un certain confort au niveau de la zone de traction ou de préhension. Ce faisant, il a été proposé de rapporter au niveau de ces zones des éléments de nature différente de celle de la zone active de la laisse ou des anses. Mais là encore, une telle opération aboutit à un surenchérissement des coûts de production.In the more general field of straps, and in particular in the context of leashes for animals and other handles for gripping bags and shopping bags, the user most often wishes to benefit from a certain comfort in the area of traction or gripping. . In doing so, it has been proposed to bring to the level of these zones elements of a different nature from that of the active zone of the leash or of the handles. But here again, such an operation leads to an increase in production costs.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
L'invention vise en premier lieu une sangle obtenue par tissage, permettant de remplir de manière satisfaisante un certain nombre des objectifs visés précédemment.The invention relates firstly to a strap obtained by weaving, making it possible to satisfactorily fulfill a certain number of the objectives referred to above.
Plus particulièrement, l'invention concerne une sangle tissée constituée d'au moins deux zones ou parties consécutives ou continues de largeurs différentes, la modification desdites largeurs étant obtenue par changement d'armures du tissage. La sangle conforme à l'invention peut également présenter une pluralité de zones à largeur modifiée, notamment à fonction décorative.More particularly, the invention relates to a woven strap made up of at least two consecutive or continuous zones or parts of different widths, the modification of said widths being obtained by changing the weaves of weaving. The strap according to the invention may also have a plurality of zones of modified width, in particular for decorative function.
En outre, et selon l'invention, la sangle présente en l'une ou en ses deux extrémités une modification de largeur se traduisant par la présence d'une structure tubulaire, résultant également d'un changement d'armures.In addition, and according to the invention, the strap has, at one or both of its ends, a change in width resulting in the presence of a tubular structure, also resulting from a change in armor.
Dans ce contexte, l'invention vise ainsi une boucle ou tel anneau, susceptibles d'être utilisés dans les domaines considérés, et notamment l'escalade, voire également dans toute activité mettant en œuvre une charge, qui soit à la fois léger, résistant sur le plan mécanique, et relativement aisé à réaliser afin d'en diminuer les coûts de réalisation.In this context, the invention thus relates to a loop or such ring, capable of being used in the fields considered, and in particular climbing, or even also in any activity implementing a load, which is both light, resistant mechanically, and relatively easy to produce in order to reduce the production costs.
Cette boucle ou cet anneau est constitué d'une sangle réalisée par tissage, dont les deux extrémités sont solidarisées l'une avec l'autre par couture. Elle se caractérise : " en ce que limitativement les zones de couture de chacune des deux extrémités sont tabulaires, le reste de l'anneau étant plat ; " et en ce que lesdites zones de couture sont superposées l'une sur l'autre. Ce faisant, attendu que seules les zones de coutures, c'est-à-dire les deux extrémités de la sangle constitutive de la boucle ou de l'anneau sont tabulaires, on aboutit à un gain de masse important.This loop or this ring consists of a strap produced by weaving, the two ends of which are joined to one another by sewing. It is characterized: "in that the seam areas of each of the two ends are tabular, the rest of the ring being flat;" and in that said seam areas are superposed on each other. In doing so, since only the stitching zones, that is to say the two ends of the strap making up the loop or the ring, are tabular, this results in a significant gain in mass.
Avantageusement, la longueur de l'une des zones de couture de l'une des extrémités est supérieure à l'autre. Ce faisant et selon une autre caractéristique avantageuse de l'invention, on réalise au voisinage immédiat de la zone de couture un témoin d'usure et/ou de surcharge. Celui-ci est constitué par le repliement sur elle-même de la base de la zone de couture formant ainsi à ce niveau une triple épaisseur, puis couture sur ces trois épaisseurs, ledit témoin d'usure et/ou de surcharge étant également réalisé en partie tubulaire de la sangle.Advantageously, the length of one of the sewing zones of one of the ends is greater than the other. In doing so and according to another advantageous characteristic of the invention, a wear and / or overload indicator is produced in the immediate vicinity of the sewing area. This consists of the folding of the base of the sewing area on itself, thus forming a triple thickness at this level, then sewing on these three thicknesses, said wear and / or overload indicator being also produced by tubular part of the strap.
Avantageusement, on intercale un ruban entre deux au moins des plis dudit témoin d'usure et/ou de surcharge. Ce ruban est préférentiellement de couleur voyante par rapport au reste de la sangle constitutive de la boucle ou de l'anneau, et ce dans un souci évident d'attirer l'attention de l'utilisateur lors de la rupture du témoin d'usure et/ou de surcharge. Selon l'invention, la couture des plis constitutifs du témoin d'usure et/ou de surcharge s'effectue au moyen d'un automate de couture, dont les diamètres respectifs du fil d'aiguille et du fil de canette sont différents. Selon cette configuration, la zone tubulaire de l'une des extrémités est repliée sur elle-même ou au niveau du changement de largeur, de telle sorte à définir une poignée ou une anse de préhension.Advantageously, a ribbon is interposed between at least two folds of said wear and / or overload indicator. This tape is preferably of a conspicuous color compared to the rest of the strap constituting the buckle or the ring, and this in an obvious concern to attract the attention of the user when the wear indicator is broken and / or overload. According to the invention, the folds constituting the wear and / or overload indicator are sewn by means of a sewing machine, the respective diameters of the needle thread and the bobbin thread being different. According to this configuration, the tubular zone of one of the ends is folded back on itself or at the level of the change in width, so as to define a handle or a grip handle.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION
La figure 1 illustre donc une laisse mettant en œuvre une sangle (10) conforme à l'invention. En l'espèce, on a matérialisé au niveau de l'une des extrémités un mousqueton (13), destiné de manière connue à permettre la fixation de la laisse sur le collier, dont est pourvu l'animal, et une poignée (14), à l'autre extrémité. Cette poignée (14) résulte de la couture (15) de la sangle sur elle-même. On obtient ainsi une poignée intégrée dans la sangle.Figure 1 therefore illustrates a leash implementing a strap (10) according to the invention. In this case, there has been materialized at one of the ends a carabiner (13), intended in a known manner to allow the attachment of the leash to the collar, which is provided with the animal, and a handle (14) , at the other end. This handle (14) results from the seam (15) of the strap on itself. This gives a handle integrated into the strap.
Selon l'invention, la zone de la sangle constitutive de la poignée présente une largeur différente que le reste de la laisse.According to the invention, the area of the strap constituting the handle has a different width than the rest of the leash.
La sangle (10) est une sangle plate. Elle est réalisée sur un métier à tisser du type commercialisé par la société MULLER (CH). Les deux zones distinctes de la laisse, à savoir la partie principale, de longueur variable, et l'extrémité faisant fonction de poignée (14), sont réalisées en modifiant l'armure du métier à tisser. Ainsi, la zone la plus longue, séparant les deux extrémités est réalisée selon une armure sergé, alors que la zone de la poignée est réalisée selon une armure taffetas. La configuration inverse est tout aussi envisageable. On dispose alors au niveau de la poignée (14), d'une largeur plus importante, propre à favoriser le confort de l'utilisateur. Avantageusement, la zone de couture (15) de l'extrémité de la sangle sur elle-même intervient au niveau de ce changement de largeur.The strap (10) is a flat strap. It is carried out on a loom of the type marketed by the company MULLER (CH). The two distinct zones of the leash, namely the main part, of variable length, and the end acting as a handle (14), are produced by modifying the weave of the loom. Thus, the longest area, separating the two ends is made in a twill weave, while the handle area is made in a taffeta weave. The reverse configuration is equally possible. There is then at the handle (14), a greater width, suitable for promoting the comfort of the user. Advantageously, the sewing area (15) of the end of the strap on itself intervenes at the level of this change in width.
La sangle est réalisée en tout matériau compatible, en termes de résistance mécanique, avec l'application envisagée. Ainsi, lorsqu'une grande résistance mécanique est requise, par exemple en vue de la destination de la sangle comme anses de sacs, ledit matériau peut être constitué en polyéthylène haute ténacité, tel que par exemple commercialisé sous la marque déposée Dyneema®. Au surplus, compte tenu de la technique de tissage mise en œuvre, la sangle, et donc le produit en résultant est susceptible de présenter tous types de décors, tel que par exemple en Jacquard. La largeur peut également varier de manière importante, en fonction, là encore, des applications envisagées. Dans une version différente de l'invention, il peut même être envisagé de ménager au niveau de la zone principale de la sangle, c'est-à-dire entre ses deux extrémités, une pluralité de variations de largeurs, telle qu'illustré au sein de la figure 3. La technologie mise en œuvre est identique à celle précédemment décrite, seul le pas des variations d'armures change. Selon une autre variante de l'invention, la variation de largeur de la sangle résulte également du passage d'un mode plat en un mode tubulaire. Ainsi, la poignée est constituée d'une partie tubulaire. Ce faisant, on augmente l'épaisseur de la sangle à ce niveau, optimisant la sensation de confort.The strap is made of any material compatible, in terms of mechanical strength, with the intended application. Thus, when high mechanical strength is required, for example for the purpose of the strap as bag handles, said material can be made of high tenacity polyethylene, such as for example sold under the registered trademark Dyneema ® . In addition, given the weaving technique used, the strap, and therefore the resulting product is likely to have all types of decor, such as for example Jacquard. The width can also vary significantly, again, depending on the intended applications. In a different version of the invention, it can even be envisaged to provide, at the level of the main zone of the strap, that is to say between its two ends, a plurality of width variations, as illustrated in FIG. within FIG. 3. The technology implemented is identical to that previously described, only the pitch of the variations of armor changes. According to another variant of the invention, the variation in width of the strap also results from the transition from a flat mode to a tubular mode. Thus, the handle consists of a tubular part. In doing so, the thickness of the strap is increased at this level, optimizing the feeling of comfort.
A cet effet, pendant la phase de fabrication sous armure sergé, pour la réalisation de la zone plate de la sangle, les fils de chaîne travaillent cote à cote deux par deux, alors que sous armure taffetas, pour réaliser la zone tubulaire, lesdits fils de chaîne deviennent alors individualisés pour justement permettre la réalisation d'une telle zone tubulaire.To this end, during the manufacturing phase under twill weave, for the realization of the flat area of the strap, the warp threads work side by side two by two, while under taffeta weave, to produce the tubular area, said threads chain then become individualized to precisely allow the realization of such a tubular area.
Comme on l'aura compris, la sangle de l'invention est réalisable de manière continue, avec changement d'armures périodique, afin de réaliser les zones plates de largeurs variables, ou l'alternance de zones plates et de zones tubulaires. La bande ainsi réalisée est découpée également automatiquement, au moyen d'une lame chauffée, induisant corollairement la soudure des fils, par exemple de polyéthylène, constitutifs. Comme on peut le concevoir, en présence de zones tubulaires, cette zone de découpe intervient hmitativement au niveau desdites zones tubulaires, de sorte que celles-ci sont systématiquement obturées en raison du chauffage des fils. Ces différentes formes de réalisation sont donc susceptibles d'être mises en œuvre pour la réalisation de produits divers, tels que laisses pour animaux, colliers, anses de sacs et autres cabas, bracelets, bracelets - montre, sangle d'instruments de musique, tels que guitare, accordéon, etc. Un mode particulier d'application de la présente invention concerne les anneaux et autres boucles dans les domaines de la sécurité, du levage, de la montagne et de l'escalade, et plus généralement, dans tous les domaines mettant en œuvre une charge. On a ainsi représenté en relation avec la figure 4 une boucle ou un anneau, plus particulièrement destiné à l'escalade conforme à l'Art antérieur. Cette boucle ou anneau est constitué d'une sangle tubulaire (1) réalisée par tissage, dont les deux extrémités (2, 3) sont solidarisées entre elles par introduction, dans l'exemple décrit, de l'extrémité (2) à l'intérieur de l'extrémité (3), puis couture de la zone de couture (4) ainsi définie. Cette introduction est rendue possible par le caractère tubulaire de la sangle (1). On conçoit que, de par le caractère tabulaire de la sangle (1), cette couture s'effectue donc sur quatre épaisseurs.As will be understood, the strap of the invention can be produced continuously, with periodic change of armor, in order to produce the flat areas of variable widths, or the alternation of flat areas and tubular areas. The strip thus produced is also cut automatically, by means of a heated blade, corollarily inducing the welding of the constituent wires, for example of polyethylene. As can be conceived, in the presence of tubular zones, this cutting zone intervenes hmitatively at the level of said tubular zones, so that these are systematically closed due to the heating of the wires. These different embodiments are therefore capable of being implemented for the production of various products, such as animal leashes, collars, bag handles and other shopping bags, bracelets, watch bracelets, strap of musical instruments, such like guitar, accordion, etc. A particular mode of application of the present invention relates to the rings and other loops in the fields of safety, lifting, mountain and climbing, and more generally, in all areas implementing a load. There has thus been shown in relation to FIG. 4 a loop or a ring, more particularly intended for climbing in accordance with the prior art. This loop or ring consists of a tubular strap (1) produced by weaving, the two ends (2, 3) of which are joined together by introduction, in the example described, from the end (2) to the inside of the end (3), then sewing of the sewing area (4) thus defined. This introduction is made possible by the tubular nature of the strap (1). It is understood that, by the tabular nature of the strap (1), this stitching is therefore carried out on four thicknesses.
L'application particulière de l'invention à ce domaine est plus particulièrement décrite en relation avec les figures suivantes et de manière générale avec la figure 5. Selon l'invention, la sangle (10) mise en œuvre pour réaliser la bouche ou l'anneau conforme à l'invention est une sangle plate, dont seules les extrémités (5, 6) sont tabulaires. Selon l'invention, la sangle (10) ne présente donc pas le caractère tubulaire entre ses extrémités. EUe présente donc à ce niveau une largeur réduite, et, par exemple, dans l'illustration décrite, une largeur de 9 millimètres, alors que la largeur de la zone de couture est typiquement de 15 millimètres.The particular application of the invention to this field is more particularly described in relation to the following figures and in general with Figure 5. According to the invention, the strap (10) used to produce the mouth or the ring according to the invention is a flat strap, of which only the ends (5, 6) are tabular. According to the invention, the strap (10) therefore does not have the tubular nature between its ends. EUe therefore has at this level a reduced width, and, for example, in the illustration described, a width of 9 millimeters, while the width of the sewing area is typically 15 millimeters.
Cette sangle (10) est également réalisée sur un métier à tisser du type commercialisé par la société MULLER (CH). Les trois zones distinctes de l'anneau, à savoir la bande centrale et les deux extrémités, sont réahsées en modifiant l'armure du métier à tisser. Ainsi, la zone la plus longue, séparant les deux extrémités (5, 6) est réalisée selon une armure sergé, alors que les zones tubulaires, correspondant aux deux extrémités sont réahsées selon une armure taffetas. Pendant la phase de fabrication sous armure sergé, les fils de chaîne travaillent cote à cote deux par deux, alors que sous armure taffetas, lesdits fils de chaîne deviennent alors individualisés pour justement permettre la réalisation d'une zone tubulaire. Cette zone tubulaire est plus large, ainsi qu'on peut bien l'observer sur les figures 6 et 7. Selon l'invention, la sangle est réalisée en polyéthylène haute ténacité, tel que par exemple commercialisé sous la marque déposée Dyneema®. Ce matériau présente les propriétés mécaniques compatibles avec l'utilisation de l'anneau en question.This strap (10) is also produced on a weaving loom of the type sold by the company MULLER (CH). The three distinct zones of the ring, namely the central band and the two ends, are re-aligned by modifying the weave of the loom. Thus, the longest zone, separating the two ends (5, 6) is produced in a twill weave, while the tubular zones, corresponding to the two ends are re-aligned in a taffeta weave. During the manufacturing phase under twill weave, the warp yarns work side by side two by two, while in taffeta weave, said warp yarns then become individualized to precisely allow the production of a tubular area. This tubular area is wider, as can be seen in Figures 6 and 7. According to the invention, the strap is made of high tenacity polyethylene, such as for example sold under the trademark Dyneema ® . This material has mechanical properties compatible with the use of the ring in question.
Selon l'invention, les deux extrémités (5, 6) de la sangle (10) sont solidarisées l'une à l'autre par couture en les superposant l'une sur l'autre. On dispose donc à ce niveau de quatre épaisseurs à savoir deux épaisseurs pour chacune des extrémités, les nombre de ces épaisseurs étant inhérent à la nature tubulaire de la sangle à ce niveau, et à ce niveau seulement. La couture est réalisée par exemple sur des automates de couture fonctionnant enAccording to the invention, the two ends (5, 6) of the strap (10) are joined to one another by sewing by superimposing them one on the other. There are therefore at this level four thicknesses, namely two thicknesses for each of the ends, the number of these thicknesses being inherent to the tubular nature of the strap at this level, and at this level only. Sewing is carried out for example on automatic sewing machines operating in
(X, Y), du type commercialisé par la société JUKI. Un tel automate permet notamment d'obtenir un certain nombre de lignes de couture (11), sensiblement parallèles entre elles, et décrivant en outre une alternance de lignes brisées ou « zigzags ». Dans l'exemple décrit, la zone de couture (7) comporte neuf de ces lignes de couture. A ce niveau, le diamètre du fil de l'aiguille de l'automate de couture est égal au diamètre de la canette dudit automate. La nature du fil est par exemple du polyamide. Il est susceptible de conférer à l'anneau résultant de la fermeture de la sangle ainsi réalisée une résistance mécanique supérieure ou égale à 2.200 DaN pour une largeur nominale de la sangle de 9 mm en zone inter-extrémités, et de 15 mm pour les extrémités, c'est à dire au niveau de la zone de couture (7), c'est-à-dire conforme à la norme NF EN 566.(X, Y), of the type sold by the company JUKI. Such an automaton makes it possible in particular to obtain a certain number of seam lines (11), substantially parallel to each other, and further describing an alternation of broken lines or "zigzags". In the example described, the sewing area (7) has nine of these sewing lines. At this level, the diameter of the needle thread of the sewing machine is equal to the diameter of the bobbin of said machine. The nature of the thread is for example polyamide. It is likely to confer on the ring resulting from the closure of the strap thus produced a mechanical resistance greater than or equal to 2,200 DaN for a nominal width of the strap of 9 mm in the inter-end zone, and 15 mm for the ends. , i.e. at the sewing area (7), that is to say in accordance with standard NF EN 566.
Comme déjà dit, la sangle constitutive de l'anneau conforme à l'invention est réahsée sur des métiers à tisser, d'un type en soi connu. De fait, eUe est réahsée de manière continue, avec changement d'armures périodique, afin de réaliser les zones plates et les zones tubulaires. La bande ainsi réahsée est découpée également automatiquement, au moyen d'une lame chauffée, induisant corollairement la soudure des fils de polyéthylène constitutifs. Comme on l'aura compris, cette zone de découpe intervient limitativement au niveau des zones tubulaires, de sorte que ceËes-ci sont systématiquement obturées en raison du chauffage des fils. Cependant, cette obturation est sans incidence, notamment en terme de main βtè uvre, et donc en terme de coût, puisque, contrairement à l'état antérieur de la technique, il n'y a pas introduction de l'une des extrémités dans l'autre, mais superposition desdites extrémités.As already said, the constituent strap of the ring according to the invention is re-aligned on weaving looms, of a type known per se. In fact, it is reahsed continuously, with periodic armor change, in order to produce the flat areas and the tubular areas. The strip thus re-sheathed is also cut automatically, by means of a heated blade, corollarily inducing the welding of the constituent polyethylene wires. As will be understood, this cutting zone intervenes restrictively at the level of the tubular zones, so that these are systematically closed due to the heating of the wires. However, this closure has no effect, in particular in terms of labor, and therefore in terms of cost, since, unlike the prior art, there is no introduction of one of the ends into the 'other, but superposition of said ends.
Selon une caractéristique de cette forme particulière de l'invention, l'anneau est également muni d'un témoin d'usure et/ou de surcharge (8). Celui-ci est aménagé au niveau de l'une (5) des deux extrémités de la sangle (10). A cet effet, la zone tubulaire de l'extrémité (5) est de longueur supérieure à la zone tubulaire de l'extrémité (6), afin justement de permettre la réahsation de ce témoin d'usure et/ou de surcharge.According to a characteristic of this particular form of the invention, the ring is also provided with a wear and / or overload indicator (8). This is arranged at one (5) of the two ends of the strap (10). For this purpose, the tubular zone of the end (5) is of length greater than the tubular zone of the end (6), in order precisely to allow the reahsation of this wear and / or overload indicator.
Celui-ci est réalisé par rephement selon trois épaisseurs de la base de ladite extrémité (5) de la sangle (10), tel que l'on peut bien observer notamment sur la figure 5. Il s'étend sur une longueur X.This is made by repheating according to three thicknesses of the base of said end (5) of the strap (10), as can be observed in particular in FIG. 5. It extends over a length X.
Après rephement, donc à plat, à l'instar de la zone de couture (7) précédemment décrite, on procède à la couture de cette zone (8), également au moyen d'un automate de couture, par exemple de type JUKI, selon le même principe d'une succession de lignes de couture (12), sensiblement parallèles entre elles et formant zigzags. Cependant, pour la réalisation de ce témoin d'usure et/ou de surcharge, le diamètre du fil d'aiguille est différent du diamètre du fil de la canette dudit automate. En l'espèce, on choisit un diamètre inférieur pour le fil de la cannette par rapport au diamètre du fil d'aiguille. En outre, le nombre de lignes de couture (12), outre la nature des fils de couture, va dépendre de la valeur à laquelle on souhaite voir se rompre le témoin de surcharge et/ou d'usure. Ainsi, ce déclenchement ou cette rupture va intervenir lorsque les fils de la canette, constituant boucles après opération de couture proprement dite, vont rompre en raison de leur diamètre inférieur à celui des boucles réalisées par le fil d'aiguille, et fermées sur lesdites boucles en fil de cannette en cas de surcharge, ou lorsque les fils de couture vont être usés de par les frottements répétés de l'anneau, et donc de la zone du témoin (8) sur les rochers notamment.After fitting, therefore flat, like the sewing area (7) previously described, this area (8) is sewn, also by means of a sewing machine, for example of the JUKI type, according to the same principle of a succession of seam lines (12), substantially parallel to each other and forming zigzags. However, for the production of this wear and / or overload indicator, the diameter of the needle thread is different from the diameter of the bobbin thread of said automaton. In this case, we choose a smaller diameter for the bobbin thread compared to the diameter of the needle thread. In addition, the number of sewing lines (12), in addition to the nature of the sewing threads, will depend on the value at which it is desired to see the overload and / or wear indicator break. Thus, this triggering or this breaking will occur when the threads of the bobbin, constituting loops after sewing operation proper, will break due to their diameter smaller than that of the loops produced by the needle thread, and closed on said loops in bobbin thread in the event of overload, or when the sewing threads are going to be worn out by the repeated friction of the ring, and therefore of the zone of the witness (8) on the rocks in particular.
Lorsque le témoin d'usure et/ou de surcharge a joué son rôle, il s'étend alors sur une longueur de 3X (figure 7).When the wear and / or overload indicator has played its role, it then extends over a length of 3X (Figure 7).
On a représenté en relation avec les figures 8a à 8d les différentes étapes de déclenchement du témoin d'usure et/ou de surcharge avec :The various stages of triggering the wear and / or overload indicator are shown in relation to FIGS. 8a to 8d with:
" figure 8a : état du témoin au repos, " figure 8b : début de déformation du témoin sous l'effet de la traction, " figure 8c : fin de déformation et rupture du fil de couture, * et enfin, figure 8d : rupture du témoin avec allongement de l'anneau de deux fois la longueur X respective du témoin compte tenu de la manière dont il est réahsé."figure 8a: state of the indicator at rest," figure 8b: beginning of deformation of the witness under the effect of traction, "figure 8c: end of deformation and break in the sewing thread, * and finally, figure 8d: break in witness with extension of the ring of twice the respective length X of the witness taking into account the manner in which it is re-sheathed.
Malgré la rupture effective du témoin (8), l'anneau ou la boucle conserve une résistance mécanique supérieure ou égale à sa valeur nominale, et dans l'exemple décrit, supérieure ou égale à 2.200 DaN. En effet, cette rupture n'affecte pas la zone de couture proprement dite (7) d'une part, en raison du fait que les fils de couture de cette zone (aiguille et canette) sont de même diamètre, et que d'autre part, le nombre de lignes de couture (11) à ce niveau est supérieur au nombre de lignes de couture (12) du témoin (8). En outre, comme cette rupture est susceptible d'intervenir qu'au niveau d'une zone tubulaire de la sangle, elle ne désorganise pas sa structure intrinsèque inhérente au mode de tissage, puisque seuls les fils de couture sont concernés. Avantageusement, on munit l'intérieur de l'une ou l'autre des zones de pliage du témoin d'usure et/ou de surcharge d'un ruban (9), avantageusement coloré, l'objectif recherché étant d'attirer l'attention de l'utilisateur de l'anneau lorsqu'il y a effectivement rupture dudit témoin. Ce ruban est simplement cousu, par exemple par points droits, sur l'envers ou l'endroit de la sangle, bien évidemment à l'aplomb de la zone effective du témoin (8).Despite the actual failure of the indicator (8), the ring or the loop retains a mechanical resistance greater than or equal to its nominal value, and in the example described, greater than or equal to 2,200 DaN. Indeed, this break does not affect the actual sewing area (7) on the one hand, due to the fact that the sewing threads of this area (needle and bobbin) are of the same diameter, and that other hand, the number of seam lines (11) at this level is greater than the number of seam lines (12) of the indicator (8). In addition, as this break is likely to occur at a tubular area of the strap, it does not disrupt its intrinsic structure inherent in the weaving mode, since only the sewing threads are concerned. Advantageously, the interior of one or the other of the folding zones of the wear and / or overload indicator is provided with a strip (9), advantageously colored, the objective sought being to attract the attention of the user of the ring when there is actually rupture of said witness. This ribbon is simply sewn, for example by straight stitches, on the reverse or the place of the strap, obviously above the effective area of the witness (8).
On conçoit tout l'intérêt de l'anneau ou de la bouche conforme à l'invention d'une part, en raison de sa facilité de réalisation, n'induisant pas de perte de temps trop importante, et partant, insusceptible d'en grever le coût de réalisation, et d'autre part en raison de la mise en œuvre d'un tel témoin d'usure et/ou de surcharge, optimisant les conditions de sécurité et d'utilisation d'un tel anneau.One understands all the interest of the ring or the mouth in accordance with the invention on the one hand, because of its ease of realization, not inducing too much loss of time, and consequently, insusceptible in burden the cost of production, and secondly due to the implementation of such a wear and / or overload indicator, optimizing the safety and use conditions of such a ring.
Et de manière plus générale, on conçoit également tout l'intérêt de la sangle de l'invention, qui permet, de manière relativement simple et automatisée, de disposer d'un élément déclinable quasiment à l'infini, tant en termes de dimensions qu'en termes de décoration, pour toute utilisation mettant en œuvre une traction ou une fonction de levage, voire simplement décorative, tout en optimisant le confort d'utilisation. And more generally, we also understand the advantage of the strap of the invention, which makes it possible, in a relatively simple and automated manner, to have an element that can be used almost infinitely, both in terms of dimensions and '' in terms of decoration, for any use involving traction or a lifting function, or even simply decorative, while optimizing user comfort.
