Definitions

  • the present invention relates to a non-slip sole. It relates more particularly to a sole having a plurality of cavities occupied by filling particles. The invention also relates to a method of manufacturing such a sole.
  • document FR2843685 discloses an aquatic shoe provided with a rough bottom surface. This surface has a non-slip surface state consisting of an elastic fabric embedded in a thin layer of rubber material.
  • FR 2722376 which relates to a non-slip surface of the type comprising a network of relief sculptures.
  • the described solution consists in that said sculptures are formed of a transverse network of narrow channels extending from one edge to the other discontinuously, a channel being defined by U-shaped lines.
  • Document FR2709929 discloses a non-slip sole having teeth protruding from the sole and resilient studs also protruding extending between the teeth and having a height at rest substantially equal to that of the teeth.
  • the document FR2661322 relates to a rigid sole of polyvinyl chloride (PVC) of the type comprising a sole body provided with at least one insert in contact with the ground and forming a wear surface.
  • the inserts are made of polyvinyl chloride of lower hardness than the polyvinyl chloride of the body of the sole.
  • a first object of the invention to provide a sole provided with friction characteristics conferring good slip characteristics, especially on very smooth floors, on wet floors, or on dry ice or wet.
  • Another object of the invention is to provide a non-slip shoe sole whose non-slip characteristics persist despite the wear of the sole.
  • the invention provides a shoe sole comprising an outsole, an insole and a midsole, extending between the insole and the outsole, the outsole being made of an elastomeric material. having a plurality of cavities filled with cavity-filling particles which are in the solid state at ambient temperature, a plurality of open cavities forming micro-reliefs distributed over the external surface of the outsole in the new state, and during wear of the sole, due to the distribution of the cavities in the mass thereof, new cavities being gradually released.
  • microreliefs generated by the cavities portions present on the surface of the sole provides a mechanical effect increasing the coefficient of friction of the the sole. This effect is particularly beneficial on smooth ground, wet or wet ground, and even on ice (dry or wet).
  • the soles according to the invention form a non-compressible structure, providing many advantages in terms of mechanical behavior.
  • the cavity filling particles are soluble in water. This embodiment allows for a sole whose contact surface with the ground is dotted with microcavities providing a gripping effect with the ground. As soon as the sole wears out, new cavities and particles are released to allow continuity of the adhesion properties related to the cavities.
  • the filling particles are salts. This type of particle has the advantage of great ease of mixing with the elastomeric materials.
  • the filler particles are chosen from the list comprising chlorates or perchlorate, potassium, ammonium or magnesium sulphates and in particular MgSO 4 and more preferably anhydrous magnesium sulphate. .
  • the average diameter of the particles is between 0.01 mm and 1 mm and more preferably between 0.01 mm and 0.3 mm and even more preferably between 0.01 and 0.1 mm.
  • the cavities are distributed in the elastomeric material in a substantially homogeneous manner.
  • the filling particles occupy between 15% and 60% of the volume of the outsole, and more preferably between 25% and 35% of the volume of the outsole.
  • the invention also provides a method of manufacturing a shoe sole as previously described, in which a plurality of filler particles are incorporated in an elastomeric material and mixed with the latter to form a substantially uniform mixture, the resulting mixture is then vulcanized in an outer sole-shaped mold specifically provided for this purpose.
  • FIG 1 is an enlarged schematic representation of an example of a portion of an outsole having cavities and filler particles
  • FIG 2 is a schematic representation of a section of an example of a shoe sole. DETAILED DESCRIPTION OF THE INVENTION
  • outsole means the outsole, that is to say the part of the sole which is in contact with the ground.
  • midsole or “midsole” means the part of the sole which extends substantially under the entire foot, against the outsole, and between the latter and the insole or first.
  • insole or "first” or “first of assembly” means the part of the sole in contact with the foot under which successively extend the midsole and the outsole.
  • Figure 2 illustrates an example of sole 1 of the shoe according to the invention.
  • This sole comprises an outsole 2, an insole 4 and a midsole 3, extending between the insole 4 and the outsole 2.
  • Figure 1 schematically illustrates an enlargement in elevation of a sole sole.
  • a plurality of filling particles 6 occupy part of the volume of the sole. At room temperature, these particles are in the solid state. Each of the cavities is usually occupied by a single particle. Occasionally, several particles may occupy the same cavity. The particles are distributed substantially uniformly in the body of the soleplate.
  • the filling particles 6 occupy between 15% and 60%, and more preferably between 25% and 35% of the volume of the sole.
  • An unfused sole has a plurality of cavities. Those on the outer surface 8 of the sole provide microreliefs, increasing the coefficient of friction of the sole. The edges produced by the cavities Updated open areas on the sole surface contribute to the increased coefficient of friction of the sole.
  • the cavity filling particles 5 are soluble in water. With the progressive wear of the sole, new cavities are gradually released. The particles are then brought into contact with the environment. As soon as the sole is in the presence of water or moisture, the particles are removed by dissolution.
  • the particles are not necessarily soluble in water. These are then evacuated by a mechanical effect. The newly released particles, during contact and soil friction phases, are ejected. Even if some particles remain hooked longer, with the wear of the sole around them, the holding effect diminishes and the particles then leave the remaining cavity portions.
  • the particles When released, the particles are removed from the cavities either by dissolution with a wet medium and / or by tearing due to the friction of the sole with the ground.
  • the microreliefs thus created can then fully enter in contact with the ground.
  • Each cavity then contributes to increasing the coefficient of friction.
  • the high density of cavities released on the surface of the sole contributes to producing a particularly adherent sole.
  • Salts preferably soluble in water, can be used to make the filling particles 6.
  • salts such as chlorates (NaCl) or perchlorate, potassium, ammonium or magnesium sulphates and in particular MgSO 4 and, more preferably, anhydrous magnesium sulphate are used.
  • the mean diameter of the particles 5 is between 0.01 mm and 1 mm and more preferably between 0.01 mm and 0.3 mm and even more preferably between 0.01 and 0.1 mm.
  • the invention also provides a method of manufacturing an outer sole of a shoe as described in the preceding paragraphs.
  • One of the key phases of the process concerns the incorporation of a plurality of filler particles 6 into the green elastomer mixture.
  • the elastomeric material with the added particles is mixed to form a substantially uniform hybrid material.
  • the resulting mixture is then placed in a mold-shaped sole to be vulcanized.
  • the temperatures and vulcanization times are substantially the same as for a conventional sole.
  • the filler particles added to the elastomeric material each occupy a volume that allows, during the vulcanization phase, to generate microcavities. These microcavities are distributed in the outsole. The presence of the particles makes it possible to form cavities without the need to use chemical additives that generate bubbles during the vulcanization phase.
