Abstract

Impervious sock that can lose its shape and take the shape of the foot. The invention consists of an impervious cotton sock (1) coated with rubber material (2) with a spongy reinforcement at the heels (3) to protect them from shocks as well as for adhesion or surface grip by way of sole (4). In addition to the mechanical protection, this invention enables support of the joints, tendons and muscles of the foot. The spongy reinforcement, when it is made of shape memory foam, is also suitable for feet with shape anomalies, plantar warts or heel spurs. After 1 to 5 hours of use, the coating formulation makes it possible for the article to take the shape of the foot exactly and to thus form a second skin which confers feeling and dexterity to the foot in addition to imperviousness. This invention is specifically designed for beach football; it may also be used for all activities at the edge of the beach as well as for industrial or domestic work requiring imperviousness, flexibility, dexterity and feel by the foot at the same time as its protection against mechanical attacks.

Le football de plage (Beach soccer) est pratiqué à pieds nus, c'est essentiel pour « sentir » la balle et pour la spécificité du jeu. De plus les règles internationales de ce jeu, soucieuses de limiter les blessures, interdisent le port de chaussures à semelles et tolèrent les chaussettes. Le problème est que ceci, ainsi que toutes autres activitésBeach soccer is practiced barefoot, it is essential to "feel" the ball and the specificity of the game.

La formulation du matériau constitutif du revêtement caoutchoutique est réalisée de façon à diminuer le taux de réticulation. Ceci permet à l'article, après 1 à 5 heures d'usage, de prendre exactement la forme du pied et de constituer ainsi une seconde peau qui confère, en plus de Pétanchéité, le toucher et la dextérité du pied. Dans la forme de réalisation selon la figure 1, il s'agit d'une chaussette en coton comme support (1 ) qui permet un certain confort de contact et facilité d'habillage, avec un revêtement étanche et très souple (2) en latex de caoutchouc naturel ou de synthèse tel que nitrile, polyuréthane ... ou en plastisols. La hauteur de ce revêtement peut aller du niveau de la cheville jusqu'au genou pour les applications nécessitant de telles hauteurs Un grip de surface peut être appliqué sur revêtement (2) et permettant de diminuer le coefficient de glissement et ainsi un meilleur contrôle du ballon notamment lorsqu'il est humide La mousse anti-contusions au niveau du talon (3) est réalisée en matériau alvéolaire souple à cellules ouvertes tel que la mousse de latex, polyuréthane ou polyoléfines à forte densité. De la mousse à mémoire de forme ou viscoélastique peut être utilisée dans le cas de pieds qui présentent des anomalies de forme, des verrues plantaires ou ayant des épines du calcanéum.. Le renfort caoutchoutique en guise de semelle (4) est une couche supplémentaire de très grande flexibilité en caoutchouc naturel ou de synthèse, en plastisol ou matériaux similaires ayant subi une opération d'adhérisation par un solvant afin de lui conférer une rugosité de surfaceThe formulation of the material constituting the rubber coating is performed so as to reduce the degree of crosslinking. This allows the article, after 1 to 5 hours of use, to take exactly the shape of the foot and thus constitute a second skin that gives, in addition to sealing, the touch and dexterity of the foot. In the embodiment according to Figure 1, it is a cotton sock as a support (1) which allows a certain comfort of contact and ease of dressing, with a waterproof and very flexible coating (2) latex natural or synthetic rubber such as nitrile, polyurethane ... or plastisols. The height of this coating can go from the level of the ankle to the knee for the applications requiring such heights A surface grip can be applied on coating (2) and making it possible to decrease the coefficient of sliding and thus a better control of the balloon especially when it is wet The anti-bruising foam at the heel (3) is made of flexible cellular open cell material such as latex foam, polyurethane or high density polyolefins. Memory foam or viscoelastic foam can be used in the case of feet that have abnormal shape, plantar warts or having calcaneus spines .. The rubber reinforcement as a sole (4) is an additional layer of very high flexibility in natural or synthetic rubber, in plastisol or similar materials that have undergone solvent bonding to give it a surface roughness
Dans d'autres formes de réalisations (figure 2) cette invention peut être effectuée sans le support coton et/ou en plusieurs parties dont l'assemblage des différentes extensions du type (5) permet de couvrir de manière étanche les pieds jusqu'à la ceinture. Dans ce dernier cas l'étanchéité est assurée par le chevauchement des différentes parties sur environ 7 cm avec un taux de déformation par allongement dans ces zones allant de 25% à 100%. La réalisation de cet article peut être effectuée par trempé simple en multicouche ou par trempé coagulant d'une forme de pied habillée d'une chaussette coton dans un mélange formulé par exemple selon ;In other embodiments (Figure 2) this invention can be carried out without the cotton support and / or in several parts, the assembly of the various extensions of the type (5) can be sealed to the feet up to belt. In the latter case the seal is provided by overlapping of the different parts of about 7 cm with a deformation by elongation rate in those areas from 25% to 100%. The embodiment of this article can be carried out by simple dipping in multilayer or by dipping coagulant of a foot shape dressed with a cotton sock in a mixture formulated for example according to;
Latex de caoutchouc: 100 phr, ZDEC : lphr, ZMBT : 0.2 phr, Soufre : lphr, ZnO : 2 phr, Ricinoléate de potassium : 0.05 phr, Tensioactif non ionique : 0.02 phr. Le coagulant est une solution de chlorure de calcium dans l'eau à 25%. Après les trempes qui auront permis l'obtention d'une épaisseur du revêtement d'environ 1 à 2 mm une trempe permettant une enduction supplémentaire de la plante du pied est effectuée dans un mélange de formule similaire ayant, en plus, 0.6 phr d'épaississant cellulosique et., par conséquent, une viscosité de 5000 à 6000 mPa.s. A l'issue de cette trempe, cette dernière couche de semelle est trempée dans un solvant comme le toluène ou xylène afin de lui conférer son grip de surface. Le renfort en mousse anti-contusion est réalisé en mousse de latex SBR obtenue par battage mécanique selon le procédé Dunlop ou Tallalay et coulée dans des moules ayant la forme requise Ces mousses sont soit collées à l'intérieur de la chaussette comme représente sur la figure 1 (3) soit insérées entre la chaussette et la première couche de revêtement caoutchoutique. Rubber Latex: 100 phr, ZDEC: lphr, ZMBT: 0.2 phr, Sulfur: lphr, ZnO: 2 phr, potassium Ricinoleate: 0.05 phr, nonionic surfactant: 0.02 phr. The coagulant is a solution of calcium chloride in water at 25%. After quenching which has made it possible to obtain a coating thickness of approximately 1 to 2 mm, a quenching allowing additional coating of the sole of the foot is carried out in a mixture of similar formula having, in addition, 0.6 phr of cellulosic thickener and, therefore, a viscosity of 5000 to 6000 mPa.s. After this quenching, this last layer of sole is soaked in a solvent such as toluene or xylene to give it its surface grip. The anti-bruising foam reinforcement is made of SBR latex foam obtained by Dunlop or Tallalay mechanical beating and poured into molds having the required shape. These foams are either glued inside the sock as shown in the figure. 1 (3) is inserted between the sock and the first layer of rubber coating.
