Definitions

  • the present invention relates to the sole of a shoe made of polyurethane with an insert which varies the consistency thereof and the response thereof to stresses and increases grip thereof on the ground.
  • soles for shoes in particular sports shoes, which have inserts, normally made of elastomeric material with differentiated rigidity, which are designed to vary the characteristics of elasticity, compressive strength, torsional strength, etc. of the material making up the sole.
  • the above inserts are generally positioned in the heel of the shoe, which should be what has the greatest influence on the overall behaviour of the shoe when worn.
  • the purpose of the present invention is to provide a sole for a shoe that will overcome the drawback referred to above.
  • the reference number 2 designates the sole of a shoe, in the case illustrated a shoe of a sports type made by moulding from polyurethane material, adopting an injection-moulding process or obtained by casting, the said sole being provided with a surface of contact with the ground made, in the case illustrated, with a pattern having projections 3.
  • the above-mentioned sole has, in the central part of the heel 3, i.e., in the part of the sole on which the heel of the foot rests, an insert 4 preferably having a cylindrical shape, one end face 5 of which is designed to come into contact with the ground, has a preferably elliptical shape and is made with a substantially hemispherical axial groove 6 which bestows thereon a shape similar to a suction pad.
  • the insert 4 has a circumferential groove with a preferably semicircular cross section 7, but may have a cross section of some other shape, for example, a trapezoidal one ( Figure 12), without thereby departing from the sphere of protection of the present invention.
  • the aforesaid insert 4 may be made indifferently of rubber, thermoplastic rubber (TR) or else of a polyvinyl material (PVC).
  • TR thermoplastic rubber
  • PVC polyvinyl material
  • the grooved profile, which may be semicircular, trapezoidal or at an angle, of the side wall of the insert 4 enables the problem of joining of two different materials such as, for instance, polyurethane, with which the sole is built and the rubber or TR that constitutes the material of the insert 4, to be overcome without any difficulty.
  • a sole with a high heel suitable for shoes worn by ladies, which has just one insert in a position corresponding to the heel (see Figures 3 and 4), as described previously, all the other soles, whether for sports use or for town use, have a second insert 9 made like the first, except for the elliptical shape of the face.
  • the insert 9 is englobed in the sole, substantially in the area where the front part of the foot rests on the ground, i.e., corresponding to the base of the big toe of the user.
  • the insert is provided with holes 10 for the purpose both of airing the inside of the shoe and of conferring on the insert a differentiated compressive strength.
  • the said holes will be substantially parallel to the axis A of the insert in the case where the aim is to air the inside of the shoe.
  • the top face of the insert 4 will have a part 11, provided with holes 10, which will protrude from the surface of the inlay-sole 12 inside the shoe (see Figure 7).
  • the aforesaid holes 10 may be perpendicular to the axis A (see Figures 8 and 9) in the case where the aim is just to vary the rigidity and/or elastic response of the sole.
  • Figures 10 and 11 illustrate a further embodiment of the insert, in particular, of the face on the outside of the shoe, which comes into contact with the ground.
  • the said face is provided with a suction pad 13 made having a profile such as to enable a vacuum or suction effect to be obtained inside it.
  • the suction pad is surrounded by a circular groove 14, which separates it from the outer edge 15 of the sole, in so far as the edge of the suction pad 13 widens, and it is, in effect, the presence of this groove that enables its widening.
  • the insert 4 may be set in the sole 2 so as not to project with the top edge from the top edge of the sole.
