Abstract

The overshoe has an automatic adjustable elastic strap (1) permitting adjustment of size of a town shoe. The strap is connected to a textile or leather forepart covering a toecap (2) resistant to 200 joules, and a slip resistant half sole (3) made of polymer permits ground adherence. A leather or textile lining (6) permits dressing interior of the toecap, and a leather or textile apron (7) protects back heel.

Description

The present invention relates to a protective over-shoe, reusable, and directly adjustable to the street shoes with great ease, allowing visitors to occasionally move in areas at risk, as part of the personal protective equipment.

• difficulté de détenir toutes les pointures de chaussures, et en quantité importante pour équiper les visiteurs,
• nécessité d'un stock permanent concernant les chaussures de sécurité destinées aux visiteurs,
• coût très important compte tenu du prix de revient relativement élevé des chaussures de sécurité et suivi très précis. En outre, il est également nécessaire que les visiteurs se déchaussent au bénéfice de chaussures de sécurité, ce qui a pour effet d'entraîner un encadrement lourd.
• Enfin, il convient de procéder après utilisation des chaussures, au nettoyage et à la désinfectation ou à la destruction de celles-ci pour des raisons d'hygiène.

Traditionally, when visiting factory or construction sites, when the wearing of safety shoes is mandatory, several disadvantages are present:

• difficulty of holding all the sizes of shoes, and in large quantity to equip the visitors,
• need for a permanent stock of safety shoes for visitors,
• cost very important given the relatively high cost of safety shoes and very precise tracking. In addition, it is also necessary for visitors to take off shoes for the benefit of safety shoes, which has the effect of resulting in heavy supervision.
• Finally, it is advisable to proceed after using shoes, cleaning and disinfecting or destroying them for reasons of hygiene.

This invention aims to overcome the drawbacks mentioned above and has the main objective of allowing visitors not to take off shoes during factory visits or casual passages in risk areas, the product fitting directly on the shoe of town. In addition, the foot is not in contact with the product, there is no need for cleaning. Finally, only three sizes cover the sizes from 35 to 48, which is a lower cost and easier to adapt.

However, it is by no means an element intended to transform the usual shoes into safety shoes for workers in their professional work places, but an overshoe that is directly adjustable to the city shoe intended for factory or construction site visitors.

The originality of the invention lies in its extreme simplicity that allows factory visitors who would occasionally move in risk areas during factory visits or construction sites, to have these over-shoes directly adjustable to the shoes of town thanks to the elastic strap (1), without taking off shoes, and without having to look for a precise size, three sizes covering all the sizes; which has the effect of generating a cost much lower than the investment for real safety shoes.

According to another characteristic of the invention, the tip of the over-shoe provides full toe protection for visitors, resistant against shocks equivalent to 200 Joules, and against the risk of crushing under a maximum load of 1500 daN .

• La figure 2 représente une vue du dessus du produit de l'invention,
• La figure 3 représente une vue du dessous du produit de l'invention,
• La figure 4 représente une vue de l'arrière du produit de l'invention.

En référence à ces dessins, le produit est composé :

• d'un élastique automatiquement ajustable (1);
• un embout résistant à 200 joules, asymétrique et recouvrant plusieurs pointures (2),
• un patin antiglisse en polymère (3),
• une ½ première de montage antistatique (4),
• une empeigne ou un dessus en cuir (5),
• une doublure en cuir et/ou textile pour l'habillage de l'intérieur de l'embout (6),
• un plastron de protection arrière talon en cuir et/ou textile (7).

Other features, objects and advantages of the invention will emerge from the detailed description which follows with reference to the accompanying drawings which represent a non-limiting embodiment. In these drawings which form an integral part of the present invention:

• The figure 1 represents a view of the profile of the invention,
• The figure 2 represents a view from above of the product of the invention,
• The figure 3 represents a view from below of the product of the invention,
• The figure 4 represents a rear view of the product of the invention.

With reference to these drawings, the product is composed of:

• an automatically adjustable elastic (1);
• a tip resistant to 200 joules, asymmetrical and covering several sizes (2),
• a non-slip polymer pad (3),
• a first antistatic assembly (4),
• a leather upper or upper (5),
• a leather and / or textile lining for covering the inside of the mouthpiece (6),
• a rear bumper protector leather and / or textile (7).

• Une protection des orteils contre les chocs équivalents à 200 Joules,
• Une protection des orteils contre les risques d'écrasement sous une charge maximale de 1.500 daN,
• Une résistance à l'arrachement de l'élastique supérieur à 900 N,
• Des caractéristiques ergonomiques particulières conformes à la norme EN ISO 20345 :2004,
• Une résistance au déchirement de la tige,
• Une force d'adhésion tige/semelle de marche conforme à la norme EN ISO 20345 :2004.

According to the invention, this method is characterized in that it consists in allowing:

• Toe protection against shock equivalent to 200 Joules,
• Toe protection against the risk of crushing under a maximum load of 1,500 daN,
• A tensile strength of the elastic greater than 900 N,
• Particular ergonomic features in accordance with EN ISO 20345: 2004,
• Resistance to tearing of the stem,
• An adhesion force rod / foot plate in accordance with EN ISO 20345: 2004.

According to the invention, the product finally has specific characteristics as it consists of an extra large metal tip to receive or cover all types of shoes (sizes 35 to 48) and protecting the toes from shocks, a top in leather or textile allowing the dressing of the tip (5), an automatically adjustable elastic allowing the adaptation of the on-shoe on the footwear according to the size of the foot, and without any effort (1), a polymer pad allowing the adhesion to the ground (3), a leather or textile lining for the dressing of inside the mouthpiece (6), a leather or textile heelette for holding at the heel (7).

• en premier lieu, il est procédé à la coupe de tous les éléments ;
• en second lieu, il est procédé à l'assemblage par piqûre d'une partie des pièces ;
• en troisième lieu, il est procédé à l'habillage de l'embout par les éléments coupés en cuir et textiles ;
• en dernier lieu, il est procédé au collage du patin.

The invention is conceived according to a precise operating mode:

• in the first place, all the elements are cut;
• in the second place, it is proceeded to the piecing assembly of a part of the pieces;
• third, it is proceeded to the dressing of the tip by the cut elements of leather and textiles;
• finally, the gluing of the shoe is carried out.

According to the embodiments: the product can be made in all colors.

The invention, in view of its specificity is therefore susceptible of industrial application.
