Description

La présente invention se rapporte à un tissu métallique spécialement adapté à la fabrication de vêtements de protection du type "cotte de mailles".The present invention relates to a metallic fabric specially adapted for the manufacture of protective clothing of the "chain mail" type.

Il est bien connu que certaines professions telles que par exemple la boucherie en gros ou en détail exposent la main d'oeuvre à des risques de coupures pouvant avoir des conséquences extrêmement graves sinon dramatiques, et les bouchers déplorent, chaque année, au sein de leur corporation, un nombre non négligeable d'accidents entraînant une incapacité de travail définitive voire le décès de leurs victimes. Pour diminuer ce risque à caractère avant tout professionnel, de nombreux responsables de boucheries industrielles ou artisanales exigent de leur personnel le port permanent de vêtements de protection (gants et tabliers). Les bouchers eux-mêmes sentent de plus en plus l'intérêt d'une telle protection, et, un nombre croissant d'entre-eux n'envisagerait plus d'entreprendre son travail sans revêtir auparavant un vêtement protecteur.It is well known that certain professions such as for example wholesale or retail butchery expose the workforce to the risk of cuts which can have extremely serious if not dramatic consequences, and butchers deplore, every year, within their corporation, a significant number of accidents resulting in permanent incapacity for work or even the death of their victims. To reduce this risk, which is primarily professional, many managers of industrial or artisanal butcheries require their staff to wear permanent protective clothing (gloves and aprons). Butchers themselves are increasingly aware of the value of such protection, and an increasing number of them would no longer consider undertaking their work without first putting on protective clothing.

Il existe actuellement dans le commerce plusieurs types de tabliers de protection qui sont réalisés en un tissu métallique du type dit "cotte de mailles". Parmi ces tissu, ceux qui ont donné le maximum de satisfaction sont constitués par des plaquettes métalliques rectangulaires à petits côtés arrondis, assemblées au moyen d'anneaux de jonction métallique soudés passant dans des perforations de jonction prévues à cet effet au niveau des coins de la plaquette; ces plaquettes sont alignées côte à côte sur plusieurs rangées parallèles et sont partiellement superposées toujours dans le même sens et, chaque anneau de jonction assure l'assemblage de quatre plaquettes différentes au niveau des coins voisins de celles-ci. (FR-A 2 397 166).There are currently several types of protective aprons on the market which are made of a metallic fabric of the so-called "chain mail" type. Among these fabrics, those which have given the maximum satisfaction consist of rectangular metal plates with small rounded sides, assembled by means of welded metal junction rings passing through junction perforations provided for this purpose at the corners of the brochure; these plates are aligned side by side on several parallel rows and are partially superimposed always in the same direction and, each junction ring ensures the assembly of four different plates at the corners adjacent to these. (FR-A 2 397 166).

Un tel tissu présente l'avantage d'être léger et souple et donc particulièrement confortable pour son utilisateur; il n'élimine cependant pas totalement les risques de coupure, vu que la pointe d'un couteau qui est parfois très fine peut venir s'insérer dans l'espace demeurant libre entre deux plaquettes.Such a fabric has the advantage of being light and flexible and therefore particularly comfortable for its user; however, it does not completely eliminate the risk of cutting, since the tip of a knife which is sometimes very fine can be inserted into the space remaining free between two inserts.

La présente invention a pour objet de remédier à cet inconvénient en proposant un tissu métallique nouveau possédant les mêmes qualités de robustesse, de légèreté et de souplesse que le tissu susmentionné, mais réduisant les espaces libres susceptibles de permettre l'insertion de la pointe d'un couteau.The object of the present invention is to remedy this drawback by proposing a new metallic fabric having the same qualities of robustness, lightness and flexibility as the aforementioned fabric, but reducing the free spaces capable of allowing the insertion of the tip. a knife.

A cet effet, l'invention se rapporte à un tissu du type ci-dessus caractérisé en ce que chaque plaquette comporte au moins quatre perforations de liaison similaires aux perforations de jonction et réparties entre celles-ci de manière à définir, sur chaque plaquette, deux rangées de perforations similaires disposées chacune parallèlement à un grand côté de la plaquette, deux perforations de liaison voisines situées sur une même rangée d'une plaquette étant, à chaque fois, reliées à deux perforations de liaison voisines situées sur une même rangée de la plaquette directement contiguë au moyen d'un anneau de liaison similaire aux anneaux de jonction et passant dans ces quatre perforations.To this end, the invention relates to a fabric of the above type characterized in that each plate comprises at least four connecting perforations similar to the junction perforations and distributed between them so as to define, on each plate, two rows of similar perforations each arranged parallel to a long side of the wafer, two neighboring connecting perforations located on the same row of a wafer being, in each case, connected to two neighboring connecting perforations located on the same row of the directly adjacent plate by means of a connecting ring similar to the junction rings and passing through these four perforations.

Les plaquettes constituant le tissu selon l'invention sont plus longues que celles correspondant à l'art antérieur susmentionné de manière à permettre le perçage des perforations de liaison ; celles-ci peuvent, bien entendu, être en un nombre multiple de quatre quelconque, mais on ne prévoit, le plus souvent, que quatre perforations de liaison pour que les dimensions des plaquettes soient compatibles avec l'obtention d'un tissu ayant une souplesse satisfaisante.The plates constituting the fabric according to the invention are longer than those corresponding to the aforementioned prior art so as to allow the drilling of the connection perforations; these can, of course, be in any number multiple of four, but most often only four connecting perforations are provided so that the dimensions of the plates are compatible with obtaining a fabric having flexibility satisfactory.

Selon une autre caractéristique de l'invention, les anneaux de jonction relient des plaquettes voisines par leur petit côté et passent dans des perforations superposées de plaquettes voisines par leurs grands côtés.According to another characteristic of the invention, the junction rings connect neighboring plates by their short side and pass into superimposed perforations of neighboring plates by their long sides.

Par suite de cette configuration, les anneaux de jonction et les anneaux de liaison sont tous disposés dans le même sens, ce qui permet d'obtenir un tissu ayant une souplesse optimale.As a result of this configuration, the joining rings and the connecting rings are all arranged in the same direction, which makes it possible to obtain a fabric having optimal flexibility.

Pour pouvoir constituer de la manière susmentionnée un tissu du type "cotte de mailles", il est bien entendu nécessaire que dans chaque rang, les plaquettes voisines se chevauchent sans être superposées ; ceci signifie que si l'on considère le tissu disposé de manière telle que les grands côtés des plaquettes soient alignés approximativement horizontalement, dans chaque rang vertical, la rangée inférieure d'une plaquette coopère avec la rangée supérieure de la plaquette située immédiatement en-dessous ou au-dessus et ainsi de suite, ce qui correspond à un chevauchement relativement important ; au contraire, dans chaque rang horizontal, le chevauchement des petits côtés des plaquettes est très faible vu que ceux-ci sont simplement assemblés au moyen des anneaux de jonction.In order to be able to constitute in the above-mentioned manner a fabric of the "chain mail" type, it is of course necessary that in each row, the adjacent plates overlap without being superimposed; this means that if we consider the fabric arranged in such a way that the long sides of the plates are aligned approximately horizontally, in each vertical row, the lower row of a plate cooperates with the upper row of the plate located immediately below or above and so on, which corresponds to a relatively large overlap; on the contrary, in each horizontal row, the overlap of the short sides of the plates is very slight since they are simply assembled by means of the junction rings.

Compte tenu de la configuration susmentionnée, les plaquettes ont, chacune par rapport à leurs voisines, une liberté de mouvement limitée qui est fonction des dimensions d'une part des perforations et, d'autre part, des anneaux de liaison et de jonction ; le tissu peut ainsi être déplacé entre une position "de contraction" ou de chevauchement maximum des plaquettes et une position "d'extension" ou de chevauchement minimum des plaquettes.Given the above-mentioned configuration, the plates have, each with respect to their neighbors, a limited freedom of movement which is a function of the dimensions on the one hand of the perforations and, on the other hand, of the connection and junction rings; the tissue can thus be moved between a position of "contraction" or maximum overlap of the platelets and a position of "extension" or minimum overlap of the platelets.

Cette liberté de mouvement conditionne la souplesse du tissu ; elle est directement fonction des dimensions des anneaux et des perforations ainsi que de la position de ces dernières sur les plaquettes.This freedom of movement conditions the flexibility of the fabric; it is a direct function of the dimensions of the rings and of the perforations as well as of the position of the latter on the plates.

Il est bien entendu, nécessaire que la distance entre les différentes perforations de liaison soit choisie pour correspondre à la liberté de rotation susmentionnée.It is of course necessary that the distance between the various connecting perforations is chosen to correspond to the freedom of rotation mentioned above.

Bien entendu, les plaquettes tout comme les anneaux peuvent être en un matériau quelconque sans pour cela sortir du cadre de l'invention. Néanmoins et pour des questions de légèreté et donc de confort pour l'utilisateur, on opte le plus souvent pour des plaquettes en aluminium dont l'épaisseur doit être choisie la plus faible possible, tout en étant suffisante pour ne pas risquer de ruptures sous l'effet de la lame d'un couteau.Of course, the plates as well as the rings can be of any material without departing from the scope of the invention. However, for reasons of lightness and therefore of comfort for the user, we generally opt for aluminum plates whose thickness must be chosen as small as possible, while being sufficient not to risk ruptures under the effect of a knife blade.

Les anneaux de jonction et les anneaux de liaison sont, quant à eux, le plus souvent des anneaux soudés en acier inoxydable pour conférer au tissu une résistance optimale.Junction rings and link rings are most often welded stainless steel rings to give the fabric optimal resistance.

Le tissu métallique conforme à l'invention peut être utilisé pour la réalisation de vêtements de protection quelconques et notamment de tabliers de protection destinés à des bouchers.The metallic fabric according to the invention can be used for the production of any protective clothing and in particular protective aprons intended for butchers.

L'invention se rapporte également à un tel vêtement ; celui-ci est caractérisé en ce qu'il comporte des bretelles, une ceinture ainsi qu'une surface de protection constituée par des plaquettes métalliques rectangulaires munies de perforations de jonction et de perforations de liaison réparties sur deux rangées et assemblées au moyen d'anneaux'de jonction et d'anneaux de liaison.The invention also relates to such a garment; it is characterized in that it includes suspenders, a belt and a protective surface constituted by rectangular metal plates provided with junction perforations and connecting perforations distributed in two rows and assembled by means of rings 'junction and connecting rings.

Les dimensions des éléments constitutifs du vêtement conforme à l'invention peuvent, bien entendu, varier dans une large mesure et sont choisies pour obtenir parallèlement des qualités de résistance et de souplesse.The dimensions of the constituent elements of the garment according to the invention can, of course, vary to a large extent and are chosen to obtain qualities of resistance and flexibility at the same time.

L'expérience a montré que l'on obtenait des résultats particulièrement satisfaisants en choisissant de plaquettes métalliques constituées par des rectangles dont la longueur est environ comprise entre 3 et 4 cm et la largeur entre 1,5 et 2,5 cm et des anneaux ayant un diamètre compris entre environ 0,3 et 0,9 cm qui coopèrent avec des perforations de diamètre compris entre 0,25 et 0,50 cm.Experience has shown that particularly satisfactory results are obtained by choosing metal plates formed by rectangles whose length is approximately between 3 and 4 cm and the width between 1.5 and 2.5 cm and rings having a diameter between about 0.3 and 0.9 cm which cooperate with perforations with a diameter between 0.25 and 0.50 cm.

Les dimensions combinées des anneaux et des perforations sont particulièrement importantes pour garantir la souplesse du vêtement et par suite le confort de l'utilisateur.The combined dimensions of the rings and the perforations are particularly important to guarantee the flexibility of the garment and therefore the comfort of the user.

Les caractéristiques du tissu métallique ainsi que du vêtement qui font l'objet de l'invention seront décrites plus en détail en se référant aux dessins annexés dans lesquels :

  • - la figure 1 représente un tissu métallique conforme à l'art antérieur,
  • - la figure 2 représente le tissu métallique conforme à l'invention,
  • - la figure 3 est une vue schématique d'un tablier de protection réalisé dans le tissu conforme à l'invention.
The characteristics of the metallic fabric as well as of the garment which are the subject of the invention will be described in more detail with reference to the appended drawings in which:
  • FIG. 1 represents a metallic fabric in accordance with the prior art,
  • FIG. 2 represents the metallic fabric according to the invention,
  • - Figure 3 is a schematic view of a protective apron made of the fabric according to the invention.

Selon la figure 1, le tissu métallique conforme à l'art antérieur est schématiquement constitué par des plaquettes en aluminium 1 disposées côte à côte, en se chevauchant partiellement les unes les autres, toujours dans le même sens, qui sont assemblées au moyen d'anneaux de jonction 2 en acier inoxydable qui passent dans des perforations de jonction 3 qui sont prévues, à cet effet, au niveau des coins des plaquettes 1. Les anneaux de jonction 2 sont constitués par un fil soudé sur lui-même.According to Figure 1, the metal fabric according to the prior art is schematically constituted by aluminum plates 1 arranged side by side, partially overlapping each other, always in the same direction, which are assembled by means of Junction rings 2 made of stainless steel which pass through junction perforations 3 which are provided, for this purpose, at the corners of the plates 1. The junction rings 2 are formed by a wire welded on itself.

Dans ce qui suit, on considérera le tissu métallique disposé comme sur les figures, c'est-à-dire que les plaquettes 1 sont classées en rangées horizontales 5 dans lesquelles elles sont voisines par leurs petits côtés 8 et en rangées verticales 6 dans lesquelles elles sont voisines par leurs grands côtés 9.In what follows, we will consider the metallic fabric arranged as in the figures, that is to say that the plates 1 are classified in horizontal rows 5 in which they are close by their short sides 8 and in vertical rows 6 in which they are close by their long sides 9.

Selon la figure 1, chaque anneau de jonction 3 relie, d'une part, deux plaquettes 1 situées côte à côte sur une même rangée horizontale 5 en passant dans leurs perforations de jonction 3 situées en regard et, d'autre part, deux plaquettes 1 situées sur une même rangée verticale 6 en passant dans des perforations qui se chevauchent partiellement.According to Figure 1, each junction ring 3 connects, on the one hand, two plates 1 located side by side on the same horizontal row 5 passing through their junction perforations 3 located opposite and, on the other hand, two plates 1 located on the same vertical row 6 passing through perforations which partially overlap.

Par suite de cette configuration, chaque anneau de jonction 2 relie donc quatre plaquettes 1 voisines.As a result of this configuration, each junction ring 2 therefore connects four adjacent plates 1.

Comme il a été déjà indiqué, dans certains cas, la lame d'un couteau, notamment d'un couteau de boucher, peut se glisser, selon la flèche A, dans l'intervalle laissé entre deux plaquettes 1 et venir blesser son utilisateur.As has already been indicated, in certain cases, the blade of a knife, in particular a butcher's knife, can slide, according to arrow A, in the space left between two plates 1 and come to injure its user.

Selon la figure 2, le tissu métallique conforme à l'invention est également constitué par l'assemblage de plaquettes rectangulaires 10 en aluminium disposées côte à côte classées en rangs horizontaux 50 et en rangs verticaux 60 assemblées au moyen d'anneaux de jonction 20 soudés sur eux-mêmes en acier inoxydable qui passent dans des perforations de jonction 30 spécialement prévues à cet effet.According to Figure 2, the metal fabric according to the invention is also constituted by the assembly of rectangular aluminum plates 10 arranged side by side classified in horizontal rows 50 and vertical rows 60 assembled by means of welded junction rings 20 on themselves in stainless steel which pass through junction perforations 30 specially provided for this purpose.

D'une manière similaire à la configuration de l'art antérieur représentée sur la figure 1, les plaquettes 10 des rangs horizontaux 50 sont voisines par leurs petits côtés 80 tandis que les plaquettes 10 des rangs verticaux 60 sont voisines par leurs grands côtés 90 ; en outre, les petits côtés 80 des plaquettes 10 sont arrondis vers l'extérieur.In a similar manner to the configuration of the prior art shown in FIG. 1, the plates 10 of the horizontal rows 50 are close by their short sides 80 while the plates 10 of the vertical rows 60 are close by their long sides 90; in addition, the short sides 80 of the plates 10 are rounded outwards.

Il est clair que, pour obtenir un tissu ayant une souplesse susceptible de garantir le confort de l'utilisateur, il est nécessaire que les plaquettes des différents rangs 50 et 60 présentent un certain jeu les unes vis-à-vis des autres. Ce jeu est défini par les dimensions des anneaux de jonctions 20 et des perforations de jonction 30 : son existence fait que les plaquettes peuvent se déplacer entre un état pouvant être qualifié d'état "d'extension" dans lequel elles sont à une distance maximale les unes des autres, et un état pouvant être qualifié d'état "de compression" dans lequel elles sont resserrées au maximum les unes sur les autres. Pour que le tissu ait une souplesse maximum, dans l'état "d'extension", les petits côtés 80 des plaquettes 10 voisines sur les rangs horizontaux 50 sont disposés pratiquement en regard avec un très léger che- vauchevement tandis que, bien entend, les grands côtés 90 des plaquettes 10 voisines sur les rangs verticaux 60, se chevauchent notablement pour permettre la superposition des perforations 30 et, par suite, l'assemblage des plaquettes au moyen des anneaux de jonction 20.It is clear that, in order to obtain a fabric having a flexibility capable of guaranteeing the comfort of the user, it is necessary that the pads of the different rows 50 and 60 have a certain play with respect to each other. This play is defined by the dimensions of the junction rings 20 and the junction perforations 30: its existence means that the plates can move between a state which can be qualified as an "extension" state in which they are at a maximum distance from each other, and a state which can be qualified as a "compression" state in which they are tightened as much as possible on each other. So that the fabric has maximum flexibility, in the "stretched" state, the short sides 80 of the adjacent plates 10 on the horizontal rows 50 are arranged practically opposite with a very slight overlap while, of course, the long sides 90 of the adjacent plates 10 in the vertical rows 60 overlap notably to allow the superimposition of the perforations 30 and, consequently, the assembly of the plates by means of the junction rings 20.

Par ailleurs, selon la figure 2, chaque plaquette 10 comporte, outre les perforations de jonction 30, quatre perforations de liaison 11 similaires à ces dernières et réparties entre celles-ci. Chaque plaquette 10 porte ainsi deux rangées horizontales 12 et 13 de perforations similaires parallèlement aux grands côtés 90 des plaquettes 10.Furthermore, according to FIG. 2, each plate 10 comprises, in addition to the junction perforations 30, four connecting perforations 11 similar to the latter and distributed between them. Each plate 10 thus carries two horizontal rows 12 and 13 of similar perforations parallel to the long sides 90 of the plates 10.

Selon la figure 2, les deux perforations de liaison 11 de la rangée inférieure 13 de l'une des plaquettes 10 chevauchent au moins partiellement les perforations 11 correspondantes de la rangée supérieure 12 de la plaquette 10 située immédiatement en-dessous dans un rang vertical 60 et sont reliées par des anneaux de liaison 14 similaires aux anneaux de jonction 20. Les dimensions de l'ensemble ainsi constitué sont choisies de manière à correspondre au jeu susmentionné des plaquettes 10.According to FIG. 2, the two connecting perforations 11 of the lower row 13 of one of the plates 10 at least partially overlap the corresponding perforations 11 of the upper row 12 of the plate 10 located immediately below in a vertical row 60 and are connected by connecting rings 14 similar to the joining rings 20. The dimensions of the assembly thus formed are chosen so as to correspond to the above-mentioned clearance of the plates 10.

Cette configuration permet d'obtenir un tissu métallique donnant toute satisfaction en limitant la pénétration de la lame d'un couteau comme dans le tissu de l'art antérieur représenté sur la figure 1 (flèche A).This configuration makes it possible to obtain a metallic fabric giving any satisfaction by limiting the penetration of the blade of a knife as in the fabric. su of the prior art shown in Figure 1 (arrow A).

Les dimensions des plaquettes 10 ne sont, bien entendu, pas limitatives de l'invention : on obtient, toutefois, des résultats particulièrement satisfaisants avec des plaquettes constituées par des rectangles dont la longueur est environ comprise entre 3 et 4 cm et la largeur entre 1,5 et 2,5 cm ; de même, les anneaux ont, de prérérence, un diamètre compris entre 0,3 et 0,9 cm et coopèrent avec des perforations de diamètre compris entre 0,25 et 0,50 cm.The dimensions of the plates 10 are not, of course, limiting of the invention: one obtains, however, particularly satisfactory results with plates constituted by rectangles whose length is approximately between 3 and 4 cm and the width between 1 , 5 and 2.5 cm; similarly, the rings preferably have a diameter between 0.3 and 0.9 cm and cooperate with perforations with a diameter between 0.25 and 0.50 cm.

Il convient de noter que ces dimensions conditionnent la souplesse du tissu conforme à l'invention.It should be noted that these dimensions condition the flexibility of the fabric according to the invention.

Selon la figure 3, le tissu métallique susmentionné est généralement utilisé pour la fabrication de tabliers notamment destinés à des bouchers comportant une surface de protection 15 en tissu métallique à laquelle sont fixées des bretelles 16 et une ceinture 17 permettant la mise en place du tablier.According to FIG. 3, the aforementioned metallic fabric is generally used for the manufacture of aprons, in particular intended for butchers, comprising a protective surface 15 of metallic fabric to which are attached straps 16 and a belt 17 allowing the fitting of the apron.
