Definitions

  • the invention relates to a shoe sole of the type having the characteristics mentioned in the preamble to the main claim.
  • patent US8291615 describes a sports shoe that comprises a sole formed by two opposing surfaces joined at a series of protrusions between which voids are defined.
  • the present invention relates to a shoe sole comprising a main structure that defines a tread surface intended to face the ground during use of the sole and opposing sides of the sole, said main structure comprising:
  • the sole according to the present invention makes it possible to obtain an optimal distribution of the loads that occur during the foot supporting phase.
  • the load generated during the supporting of the foot on the ground is distributed in a gradual manner, thus improving walking comfort.
  • the invention also makes it possible to make optimal use of the energy accumulated during the foot supporting phase, transforming it into a pushing action.
  • the reference number 100 indicates overall a shoe sole produced in accordance with the present invention.
  • the sole 100 extends longitudinally in a toe-to-heel direction indicated with the letter X in Figure 1 .
  • the sole 100 comprises a main structure 10, which in turn includes a forefoot portion 2, a midfoot portion 3 and a hindfoot portion 4 contiguous with each other along the toe-to-heel direction X.
  • the main structure 10 is made of a relatively elastic material, for example a polymer material, which will be illustrated in greater detail below.
  • a tread surface 1 is identified in the main structure 10 of the sole 100.
  • the term "tread surface 1" identifies the surface of the sole 100 intended to face the ground during use of the sole 100, i.e. during use of a shoe comprising the sole 100 by a user.
  • This surface may be represented by that directly in contact with the ground, or said contact may take place via the interposition of additional layers not illustrated in the figure.
  • the main structure 10 comprises a bottom layer 15 on which the tread surface 1 is defined.
  • the main structure further comprises a top layer 16 facing, in use, the foot of the user.
  • the top layer 16 and the bottom layer 15 are joined at a front end 17 of the sole 100, which defines the tip, and at a rear end 18, close to the heel.
  • a reinforcing member 5 preferably made of a material with greater rigidity than the main structure 10 or, more generally, at least than the bottom layer 15.
  • the reinforcing member 5 is made of a material with a high degree of rigidity/elasticity, for example a block copolymer, such as ABS/nylon, or a polyether block amide, such as that known by the commercial name of Pebax®.
  • a further alternative is represented by carbon or by a polyurethane, preferably of the compact thermoplastic type (TPU).
  • TPU compact thermoplastic type
  • these materials are cited purely by way of example and that further alternatives can be also provided.
  • this or these are instead made of ethylene vinyl acetate (EVA) or expanded thermoplastic polyurethane (TPU).
  • the reinforcing member 5 comprises a front portion 52, arranged on the forefoot portion 2 of the sole 100, and a rear portion 54, arranged on the hindfoot portion 4.
  • the front portion 52 and the rear portion 54 are joined by a bridging section 53.
  • the reinforcing member 5 has an essentially flat development and extends to occupy the top layer 16 more or less completely. This makes it possible to prevent the user from noticing the presence of the reinforcing member 5 when wearing the shoe and, at the same time, can provide adequate support for the entire sole of the foot.
  • a through opening 20 is defined in the reinforcing member on its front portion 52.
  • said through opening will be referred to as the "forefoot through opening 20", due to its location.
  • the forefoot through opening 20 extends between the opposing sides 11, 12 of the sole 100.
  • the term "through” indicates that the opening not only passes entirely through the reinforcing member 5 but is open laterally on the opposing sides 11, 12 of the sole 100.
  • the forefoot through opening 20 passes through the shoe in a direction transverse to that defined as the toe-to-heel direction X.
  • a through opening 40 is defined in the reinforcing member 5 on its rear portion 54.
  • said through opening will be referred to as the "hindfoot through opening 40", due to its location.
  • the hindfoot through opening 40 extends between the opposing sides 11, 12 of the sole 100.
  • the hindfoot through opening 40 passes through the shoe in a direction transverse to that defined as the toe-to-heel direction X.
  • a midfoot through opening 30 is defined between the bridging section 53 and said bottom layer 15 when the reinforcing member 5 is placed between the bottom layer 15 and the top layer 16.
  • the bridging section 53 is preferably shaped in such a way that when the reinforcing member 5 is placed between the bottom layer 15 and the top layer 16, said top layer is raised relative to the bottom layer 15. In this way, the space consequently defined forms said midfoot through opening 30.
  • the bridging section 53 is arranged to support the top layer 16, so as to provide complete support for the user's foot.
  • the reinforcing member 5 makes it possible to make optimal use of the forces in play during walking, absorbing energy, thanks to its flexion, in the support phase and subsequently releasing it during the extension of the foot.
  • the reinforcing member 5 is formed as a single body.
  • the front portion 52 and the rear portion 54 of the reinforcing member comprise a respective first transverse section 55 and a second transverse section 56, which connect to the bridging section 53.
  • the first transverse section 55 is inclined towards the rear end of the sole 100, while the second transverse section 56 is inclined towards the front end of the sole 100.
  • the transverse sections 55, 56 advantageously develop respectively along a direction parallel to that of the forces generated during the phase of support of the sole on the ground, and along a direction parallel to the forces released as a result of the elastic response in the phase of extension of the foot.
  • the reinforcing member 5 is formed by two tubular elements, which define respectively the front portion 52 and the rear portion 54, connected by the bridging section 53.
  • the transverse sections 55 and 56 form a wall of the tubular elements.
  • this structure is created by the superposition of two shaped sheets 58, 59, joined at a front area 50a, a rear area 50b and a central area that defines the bridging section 53, keeping the two sheets separate in the remaining areas.
  • the reinforcing member 5 also comprises lightening openings 57, preferably created on the shaped sheets 58, 59, which advantageously allow better adhesion between the reinforcing member 5 and the top and bottom layers 15, 16.
  • the forefoot through opening 20, the midfoot through opening 30 and the hindfoot through opening 40 define voids between the top layer 16 and the bottom layer 15, respectively identified on the forefoot portion 2, the midfoot portion 3 and the hindfoot portion 4.
  • the forefoot through opening 20 and the hindfoot through opening 40 partially overlap the midfoot through opening 30.
  • the cushioning action obtained thanks to the presence of the openings can be advantageously combined with a high flexional capacity that is produced in the areas in which the openings overlap.
  • the main structure 10 as a whole is affected by three through openings in total, defined by the forefoot through opening 20, the midfoot through opening 30 and the hindfoot through opening 40.
  • the forefoot through opening 20 and the hindfoot through opening 40 partially overlap the midfoot through opening 30 along a vertical direction defined when said tread surface is supported on the ground.
  • one is arranged above the other in relation to the ground on which the sole 100 is supported.
  • the forefoot through opening 20 overlaps the midfoot through opening 30 at an area of transition between the forefoot portion 2 and the midfoot portion 3.
  • the hindfoot through opening 40 overlaps the midfoot through opening 30 at an area of transition between the hindfoot portion 4 and the midfoot portion 3.
  • the areas of overlap advantageously correspond to those in which a greater degree of flexion is required during the movement of walking.
  • the forefoot through opening 20 and the hindfoot through opening 40 overlap the midfoot through opening 30 at respective tapered ends 22, 42.
  • said reinforcing member 5 is completely embedded in the structure 10.
  • top layer 16 and the bottom layer 15 are also connected by means of two transverse extensions 13, 14, within which are embedded the transverse sections 55, 56.
  • the reinforcing member 5 is made of compact thermoplastic polyurethane (TPU), while the bottom layer 15 is made of expanded thermoplastic polyurethane (TPU), so as to obtain a combination between materials with greater and lesser degrees of rigidity in a particularly simple constructional solution.
  • TPU compact thermoplastic polyurethane
  • TPU expanded thermoplastic polyurethane
  • the reinforcing member 5 may not be present.
  • the main structure 10 comprises a first transverse extension 13 that extends from the bottom layer 15, at an area facing the forefoot portion 2, to the top layer 16 at an area facing the midfoot portion 3.
  • the first transverse extension 13 is inclined towards the rear end of the sole 100.
  • the main structure 10 also comprises a second transverse extension 14 that extends from the bottom layer 15, at an area facing the hindfoot portion 4, to the top layer 16 at an area facing the midfoot portion 3.
  • the second transverse extension 14 is inclined towards the front end of the sole 100.
  • first and second transverse extensions 13, 14 are connected bridgewise to the top layer 16 at the midfoot portion 3.
  • the transverse extensions 13, 14 advantageously develop respectively along a direction parallel to that of the forces generated during the phase of support of the sole on the ground, and along a direction parallel to the forces released as a result of the elastic response in the phase of extension of the foot.
  • the bottom layer 15 and the first transverse extension 13 is defined a void, which identifies in the forefoot portion 2 a forefoot through opening 20 that extends between the opposing sides 11, 12.

  • the reinforcing member 5 and the structure 10 are subsequently washed with suitable cleaning products.
  • an adhesive preferably of the bi-component type, is applied to the reinforcing member 5 and the structure 10.
  • the surfaces of the reinforcing member 5 and the structure 10 intended to be joined together are coated with said bi-component adhesive.
  • the structure 10 is open on the sides, and consequently it is possible to insert the reinforcing member 5 laterally, from the inner side 11 or the outer side 12 of the sole.
  • the latter may be provided with coupling elements 57a, 58a, suitable for creating a form fit with corresponding elements defined in the structure 10.
