Embodiment Construction

[0043] figure 1 shows a sole engraving which at least reproduces approximately the sole engraving in the model document filed in the United States under the number US D446912S mentioned at the beginning of this specification as a description of the prior art. It consists of square rubber lugs 11 protruding towards the lower surface of the sole from a base 12 having a thickness and softness suitable for the purpose of the sole. Each of the bumps 11 is divided into four basic blocks 14 by two slits or slots or indentations 15 intersecting at right angles. The lugs 11 are separated from each other by two sets of orthogonal grooves 16 parallel to the slits 15, said grooves having suitable dimensions to allow a good drainage of liquids transferred by the contact of the sole with the ground. The width of these grooves is usually a multiple of the width of the inner slit 15 of each lug 11 .

Abstract

The invention relates to a shoe having a sole made of an elastomer material having an improved grip on a ground and having an interface that may include an intermediate foreign material, said sole including blocks (31) separated from each other by grooves (35). The walls of the grooves (35) extend in the body of the elastomer material and define sharp-angled patterns in the outline of said blocks (31), capable of piercing said foreign material in order to establish a direct dry contact between the two surfaces. Each block (31) defines a star-shaped pattern having at least five branches in the shape of stems (32) distributed about the outline, and each stem (32) is oriented radially towards the outside of the pattern and ends in a tip. Each stem (32) is separated from the adjacent one by a recess (38) in the block outline. Finally, each block (31) has a stem (32) that is inserted into a space of the adjacent groove (35), defined by a recess (38) between adjacent stems in the outline of a second block adjacent to the first one.

Description

technical field [0001] The present invention relates to shoes provided with a sole intended to provide a good non-slip contact with a working surface that may become slippery by liquid or solid foreign objects. It can be applied to work shoes or sports shoes, for example, on inherently slippery surfaces and on very smooth natural or synthetic coverings such as Linoleum (registered trademark), varnished tiles, polished stone and metal surfaces Good grip properties are required, especially when the surface is wetted or wetted by liquids such as water, oil or blood or covered by pools of liquids or contaminated by other kinds of foreign matter such as mud or ice. Background technique [0002] Currently, falls caused by accidental slips are common and cause serious accidental injuries. This is especially true of accidents at work, and experts in the field have spent some time researching ways to reduce their frequency and severity. In particular, several manufacturers of safet...
