Abstract

The invention relates to safety shoes which comprise a protective sole incorporated into the wear sole and which is located under the insole. This protective sole is formed by a knitted non-run fibrous texture; the fibres used are aramid fibres. The invention makes it possible to obtain a safety shoe whose weight is comparable to that of a normal shoe and whose flexibility allows fatigue-free use.

Description

"Chaussure de sécurité à semelle souple "."Safety shoe with flexible sole".

La présente invention concerne les chaussures de sé curité qui sont utilisées en particulier dans certaines industries telle que la sidérurgie et dans les chantiers du bâtiment et des travaux publics. Pour protéger le dessous du pied, en particulier la voute plantaire notamment contre des objets tranchants se trouvant sur le sol, les chaussures de sécurité utilisées dans ces ateliers ou sur ces chantiers doivent comporter une semelle de protection qui est incorporé dans la semelle d'usure et qui se trouve donc en-dessous de la première de propreté. The present invention relates to safety shoes which are used in particular in certain industries such as the steel industry and in construction sites and public works. To protect the bottom of the foot, in particular the arch of the foot, in particular against sharp objects on the ground, the safety shoes used in these workshops or on these sites must include a protective sole which is incorporated in the outsole. and which is therefore below the first cleanliness.

Cette semelle de protection doit répondre à des normes précises, en particulier en ce qui concerne sa solidité, et elle est généralement constituée d'une plaque d'acier qui couvre la surface totale de la semelle d'usure. This protective sole must meet precise standards, in particular with regard to its solidity, and it generally consists of a steel plate which covers the total surface of the outsole.

La présence de cette semelle de protection en acier éli- mine toute possibilité de souplesse si bien que les chaussures de sécurité sont pénibles à utiliser du fait de l'impossibilité de plier la semelle et il en résulte une génie qui peut se traduire par une fatique importante en fin d'une journée de travail. De plus, cette semelle en acier alourdit notamment la chaussure, ce qui accroît encore la gêne créée par le port de chaussures de sécurité. Par ailleurs, il est impossible d'éviter totalement les phénomènes de corrosion sur une telle semelle en particulier du fait de l'environnement dans lequel évolue la chaussure et aussi du fait de la sueur qui peut être dégagée par le pied.Cette corrosion peut d'une part diminuer les qualités de résistance physiques de la chaussure de sécurité et, d'autre part, elle entraîne une dégradation de la chaussure de sécurité dont la durée de vie est donc limitée. The presence of this protective steel sole eliminates any possibility of flexibility so that safety shoes are difficult to use due to the impossibility of folding the sole and this results in a genius which can result in fatigue important at the end of a working day. In addition, this steel sole in particular weighs down the shoe, which further increases the discomfort created by wearing safety shoes. Furthermore, it is impossible to completely avoid the corrosion phenomena on such a soleplate, in particular because of the environment in which the shoe operates and also because of the sweat which can be released by the foot. 'On the one hand reduce the physical resistance qualities of the safety shoe and, on the other hand, it leads to a degradation of the safety shoe whose life is therefore limited.

Enfin, la semelle de sécurité en acier constitue une plaque fortement conductrice et les qualités d'isolement électrique de la chaussure sont extrêmement faibles, ce qui augmente les dangers d'électrocution. Finally, the steel safety sole constitutes a highly conductive plate and the electrical insulation qualities of the shoe are extremely low, which increases the danger of electric shock.

La présente invention a donc pour objet une chaussure de sécurité dont la semelle de protection soit à la fois souple-et légère, ne soit pas sensible à la corrosion et présente de bonnes qualités diélectriques. The present invention therefore relates to a safety shoe whose protective sole is both flexible and light, is not sensitive to corrosion and has good dielectric qualities.

La chaussure de sécurité selon l'invention est notamment remarquable en ce que la semelle de protection est constituée par une texture fibreuse indémaillable du type tricot. Une telle semelle de protection est particulièrement légère, sa structure lui confère une très grande souplesse et son tissage peut être adapté pour que la semelle de sécurité réponde aux spécifications fixées, en particulier en ce qui concerne la résistance à la perforation. The safety shoe according to the invention is notably remarkable in that the protective sole is constituted by a non-flammable fibrous texture of the knitting type. Such a protective sole is particularly light, its structure gives it great flexibility and its weaving can be adapted so that the safety sole meets the specifications laid down, in particular as regards resistance to puncture.

Avantageusement, la texture fibreuse indémaillable précitée est réalisée au moyen de fibres aramides telles que celles distribuées sous le nom commerciai "KEVLAR". Advantageously, the aforementioned non-flammable fibrous texture is produced by means of aramid fibers such as those distributed under the trade name "KEVLAR".

La texture fibreuse indémaillable constituant la semelle de protection conformément à l'invention s'étend avantageusement sur l'ensemble de la semelle d'usure. The nonwoven fibrous texture constituting the protective sole according to the invention advantageously extends over the whole of the outsole.

Selon un mode de réalisation de l'invention, ladite semelle de protection est obtenue par découpage d'un tissus indémaillable de fibres; avantageusement ce découpage s'effectue au moyen d'un lazer. According to one embodiment of the invention, said protective sole is obtained by cutting out a nonwoven fabric of fibers; advantageously this cutting is carried out by means of a lazer.

Ce mode de découpage permet à la fois d'obtenir une bonne précision et de simplifier les opérations de fabrication de ladite chaussure de sécurité. This cutting mode makes it possible both to obtain good precision and to simplify the operations for manufacturing said safety shoe.

A titre d'exemple, les demandeurs ont réalisé une chaussure de sécurité comportant une semelle de protection réalisée à partir d'un tissus indémaillable à base de fibres aramides commercialisées sous le nom commercial de "KEvIsAR; la dimension des mailles est d'environ 1 mm et les insterstices entre mailles ont des dimensions inférieures au millimètre. Les déposants ont vérifié qu'une telle semelle présente une résistance à la perforation qui est au moins égale à celle prescrite par les normes. By way of example, the applicants have produced a safety shoe comprising a protective sole made from a nonwoven fabric based on aramid fibers marketed under the trade name of "KEvIsAR; the mesh size is approximately 1 mm and the gaps between meshes have dimensions of less than one millimeter, the applicants have verified that such a sole has a resistance to perforation which is at least equal to that prescribed by the standards.

Une telle semelle de sécurité constitue une barrière diélectrique qui protège efficacement le porteur de la chaussure de sécurité contre le contact avec des sols pouvant être portés à des tensions dangereuses.  Such a safety sole constitutes a dielectric barrier which effectively protects the wearer of the safety shoe against contact with floors which can be brought to dangerous voltages.

L'invention permet également de simplifier les opérations de fabrication d'une chaussure de sécurité et d'en diminuer notablement le prix de revient.  The invention also makes it possible to simplify the operations for manufacturing a safety shoe and to significantly reduce the cost price.
