Abstract

The strap (1), comprising warp (2) and weft (3) strands, has at least one spiral steel winding (4) running parallel to the warp strands. The wire spirals are located inside sleeves along the edges or center of the strap, made from doubled and stitched layers of the textile material, with the ends of the spirals fixed to the sleeves.

Description

L'invention se rapporte à une sangle tissée.The invention relates to a woven strap.

On connaít deux types de sangles, à savoir d'une part les sangles, obtenues à partir d'un flanc homogène de matière tel du cuir, qui sont utilisées par exemple pour des bagages et d'autre part les sangles obtenues par tissage.We know two types of straps, namely on the one hand the straps, obtained from a homogeneous flank of material such as leather, which are used for example for luggage and secondly the straps obtained by weaving.

Ces dernières auxquelles se rapporte plus précisément l'invention sont utilisées pour le levage ou pour maintenir des objets sur une plate-forme.The latter to which the invention relates more precisely are used for lifting or for holding objects on a platform.

Les sangles tissées sont donc constituées par entrelacement de fils de chaíne avec des fils de trame.The woven straps are therefore formed by interlacing warp threads with weft threads.

La résistance de ces sangles dépend de la nature des fils de chaíne (section, matériau, nombre etc ....).The resistance of these straps depends on the nature of the chain son (section, material, number etc ...).

Sous l'effet d'une traction, ces sangles s'allongent nécessairement d'une valeur qui n'est pas négligeable mais qui n'est pas comparable à l'allongement d'une sangle dite élastique.Under the effect of a traction, these straps necessarily lengthen by a value which is not negligible but which is not comparable to the lengthening of a strap called elastic.

Ces sangles sont relativement faciles à couper même accidentellement et l'on comprend bien le risque de cette coupure lorsque la sangle supporte une charge.These straps are relatively easy to cut even accidentally and understands the risk of this cut when the strap supports a load.

Pour renforcer ces sangles, l'élément mécanique peut coûteux qui vient à l'esprit est un fil d'acier.To reinforce these straps, the costly mechanical element which comes to the spirit is a steel wire.

Malheureusement, le coefficient d'allongement de ce fil d'acier est tout à fait différent de celui de la sangle et par conséquent cela pose un problème.Unfortunately, the elongation coefficient of this steel wire is quite different from that of the strap and therefore this poses a problem.

Certes, on peut imaginer que le fil d'acier ne soit pas immobilisé par rapport à la sangle de sorte qu'il puisse glisser cependant cela entraíne deux problèmes.Admittedly, one can imagine that the steel wire is not immobilized compared to the strap so that it can slip however it causes two problems.

Le premier résulte que, localement, la sangle n'est pas protégée et le deuxième résulte du retour de la sangle en position initiale. The first results that, locally, the strap is not protected and the second results from the return of the strap to the initial position.

En effet, lors de ce retour l'extrémité du fil d'acier peut abímer les fibres composant cette sangle et provoquer la coupure.Indeed, during this return the end of the steel wire can damage the fibers component this strap and cause cutting.

On connaít une sangle élastique (US-1.588.180) qui consiste en différents ressorts protégés par un tissu qui est soit en matière élastique, soit formé de fils plus longs que les ressorts.We know an elastic strap (US-1,588,180) which consists of different springs protected by a fabric which is either made of elastic material or formed of more longer than the springs.

Un tel produit ne convient pas pour lever une charge.Such a product is not suitable for lifting a load.

Un des résultats que vise l'invention est notamment de remédier à ces inconvénients.One of the results which the invention aims at is in particular to remedy these disadvantages.

A cet effet, l'invention a pour objet une sangle tissée du type précité comprenant des fils de chaíne et des fils de trame, cette sangle étant caractérisée en ce qu'elle comprend parallèlement aux fils de chaíne au moins un fil d'acier spiralé.To this end, the invention relates to a woven strap of the above type comprising warp threads and weft threads, this strap being characterized by what it includes parallel to the chain son at least one coiled steel wire.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin qui représente schématiquement :

  • figure 1 : vue de dessus d'une sangle
  • figures 2 et 3 : vue en coupe de deux exemples de réalisation.
The invention will be clearly understood with the aid of the description below given by way of nonlimiting example with regard to the drawing which schematically represents:
  • figure 1: top view of a strap
  • Figures 2 and 3: sectional view of two embodiments.

En se reportant au dessin on voit une sangle 1 tissée.Referring to the drawing we see a woven strap 1.

Celle-ci se compose de fils 2 de chaíne et de fils 3 de trame.It consists of 2 warp threads and 3 weft threads.

Il pourrait s'agir également d'une sangle tricotée.It could also be a knitted strap.

De préférence, mais non limitativement, ces fils sont en polyester.Preferably, but not limited to, these threads are made of polyester.

L'allongement de ces fils et plus encore du tissu obtenu n'est, bien évidemment, pas comparable à celui d'un tissu formé de fils élastiques.The elongation of these threads and even more of the fabric obtained is, of course obviously, not comparable to that of a fabric formed of elastic threads.

Selon l'invention, la sangle comprend parallèlement aux fils de chaíne au moins un fil 4 d'acier spiralé.According to the invention, the strap comprises parallel to the chain son at minus a spiral steel wire 4.

Ce fil 4 spiralé est localisé au niveau de la lisière 5 longitudinale de la sangle.This spiral wire 4 is located at the longitudinal edge 5 of the strap.

Il peut également être inséré en partie médiane de la largeur de la sangle.It can also be inserted in the middle part of the width of the strap.

Pour maintenir ce fil spiralé, on peut le maintenir dans une poche 6 tubulaire obtenue, par exemple, (figure 3) en rabattant le bord longitudinal de la sangle ou lorsque la sangle est constituée par un tube tissé en formant un canal ou plusieurs canaux (figure 2) au moyen d'une couture reliant les parois du tube.To maintain this spiral wire, it can be kept in a tubular pocket 6 obtained, for example, (Figure 3) by folding the longitudinal edge of the strap or when the strap is formed by a tube woven forming a channel or more channels (Figure 2) by means of a seam connecting the walls of the tube.

Au repos, la longueur du fil spiralé est égale à celle des fils de chaíne du tissu.At rest, the length of the spiral thread is equal to that of the warp threads of the fabric.

Les extrémités du fil spiralé seront fixées sur chacune des extrémités de la sangle de manière à les immobiliser par exemple au moyen d'une boucle. The ends of the coiled wire will be fixed to each end of the strap so as to immobilize them for example by means of a loop.

La longueur supplémentaire du fil d'acier liée à la forme en spirale permet alors de compenser l'allongement des fibres de la sangle tissée.The additional length of the steel wire linked to the spiral shape allows then to compensate for the elongation of the fibers of the woven strap.

On obtient donc un produit renforcé.We therefore obtain a reinforced product.

La présence d'un câble métallique qui peut être mono-filament ou du type fil torsadé constitue également une prévention contre les actes de vandalisme.The presence of a metallic cable which can be monofilament or wire type twisted also constitutes a prevention against acts of vandalism.

En cas de rupture d'une partie des fils de chaíne, ce câble métallique peut reprendre provisoirement la charge.In the event of part of the chain wires breaking, this metal cable can temporarily resume charging.
