Definitions

  • the present invention relates to a sole for footwear of the type comprising the features set out in the preamble of the main claim .
  • a sole including those features is, for example, known from US 2,162,912. That document sets out a sole having anti-slip features, particularly suitable for wet surfaces. That sole is constructed from rubber and has a plurality of openings which are formed in the tread surface transversely to a longitudinal toe-to-heel direction. Those openings have a small width and limited depth except for in the case of soles for heavy boots (for example, hunting boots), in which case there is provision for them to be able to reach at a maximum the middle of the thickness of the sole itself.
  • That sole is substantially suitable for constructing technical footwear in which the above-mentioned features are of main interest.
  • Those soles are used to improve the transpiration of the foot because the holes allow ventilation of the foot inside the footwear while the barrier allows vapour to pass but prevents the passage of water. Those soles are, however, subjected to a potential blockage, including only temporary or partial blockage, of the holes which reduces the desired effect of transpiration as far as eliminating it.
  • the problem addressed by this invention is to provide a sole for footwear which allows an improvement in the flexibility of the sole, at the same time promoting the transpirability thereof and prevention of the blockage of the ventilation holes.
  • Another object of the invention is to promote the lightness of the footwear without compromising the stability and the aesthetic appearance.
  • FIG. 1 is a perspective view of a sole for footwear according to the invention.
  • FIGS. 2A and 2B are partial views of the sole according to the invention in two operating configurations
  • FIG. 3A is a plan view of a sole for footwear according to the invention.
  • Figures 3B and 3C are cross-sections of the sole of Figure 3A cut by a plane of section A and B, respectively;
  • FIG. 4 is a view of a detail of Figure 1;
  • FIG. 5A and 5B are schematic views of two different embodiments of a sole according to the invention.
  • FIGS. 6A-6C are views of different embodiments of a sole according to the invention.
  • a sole for footwear comprising a resilient structural member in which there are identified a respective forefoot zone 2, midfoot zone 3 and backfoot zone 4 which are contiguous in a toe-to-heel direction designated X.
  • the forefoot zone 2, midfoot zone 3 and backfoot zone 4 in the examples illustrated are substantially coplanar and generally define a tread surface 5 which is delimited perimetrically by a side 7.
  • the tread surface is the one which normally supports the sole during walking.
  • the toe-to-heel direction X defines at the side 7 of the sole 1 an internal side 7A and an external side 7B opposite it.
  • the three zones of the sole are coplanar, the case is further considered that they may be located in different planes, generally with the backfoot zone 4 in relief with respect to the remaining zones.
  • the tread surface 5 has incisions 8 extending transversely to the toe-to-heel direction X.
  • the incisions 8 are open until they extend through the corresponding side 7 of the sole 1, extending between the opposing sides 7A and 7B. In other words, the incisions 8 pass completely through the sole 1 from the internal side 7A of the side 7 to the external side 7B.
  • the incisions 8 comprise a first portion 9 of laminar formation extending to a first depth 10 into the sole from the tread surface 5, and a second portion 11 extending to another depth 12 into the sole from a lower outlet 16 of the first portion 9.
  • the term "laminar formation” is intended to be understood to indicate that incisions 8 are almost completely closed in the first portion 9 at least in the region of the sides 7A, 7B with the sole flat, as illustrated in Figure 2A, and also open in a book-like configuration in the region of the sides 7A, 7B of the side 7 with the sole flexed, as indicated in Figure 2B.
  • the first portion 9 of an incision 8 having a laminar formation can be obtained with a laser cutter, thereby ensuring the precision required for the portion 9 so that it can effectively have the features described above.
  • the first portion 9 has a depth 10 having an extent which is at least equal to half of the depth 12 of the second portion 11. Even more preferably, the first portion and second portion have substantially the same depth.
  • the incisions 8 involve only the midfoot zone 3.
  • the sole 1 comprises a plurality of auxiliary incisions 8' which are formed in the forefoot zone 2 and backfoot zone 4.
  • the auxiliary incisions 8' in the forefoot zone 2 and backfoot zone 4 are thicker and more spaced-apart than the incisions 8 in the midfoot zone 3. That feature contributes to a distinction between the characteristics of the sole in the different zones, also taking into account the structural differences between the incisions 8 and the auxiliary incisions 8', as will be better set out below.
  • the auxiliary incisions 8' can, unlike the incisions 8 in the midfoot zone 3, be limited only to the laminar formation of the first portion 9' over the entire depth thereof, as can be seen in Figure 3C.
  • the depth of the first portion 9' of the additional incisions 8' is generally equal to the depth 10 of the first portion 9 of the incisions 8 of the midfoot zone 3.
  • the depth of the auxiliary incisions 8' in those zones is provided to be able to be different from the depth of the laminar portion 9 of the
  • the incisions 8 and 8' have a longitudinal extent which extends transversely relative to the toe-to-heel direction X of the sole 1, with an angle of transverse incidence which can be constant (generally 90° - Figures 1 and 3) or variable in the toe-to-heel direction X ( Figures 5A and 5B).
  • the incisions 8 have a width 13, measured transversely to the longitudinal extent of the incision 8, which is less in the first portion 9 with respect to the corresponding width 14 of the second portion 11.
  • the first portion 9 has a width 13 which is constant over the entire depth 10 thereof.
  • the variation of the width between the first portion 9 and the second portion 11 is brought about in a discontinuous manner at a transition zone between the first portion 9 and the second portion 11.
  • the incision 8 is maintained sufficiently closed.
  • the depth 10 of the first portion 9 is at least equal to half of the depth 12 of the second portion 11.
  • the incisions 8 have a cross-section which is
  • the incisions 8 along the first portion 9 and the second portion 11 have a constant width over the extent thereof in terms of depth, respectively.
  • the additional incisions 8' have a constant width.
  • the second portion 11 of the incisions 8 has a multiple width 14, which is not necessarily an integer multiple, of the width 13 of the first portion 9 while the depths 10, 12 of the portions 9, 11 is preferably but not necessarily equal or similar, that is to say, in the same order of magnitude.
  • the incisions 8 are not necessarily provided over the whole of the tread surface of the sole, the presence thereof being preferably limited to the midfoot zone 3, or at the limit in the positions immediately adjacent thereto.
  • the incisions 8 may also involve partially or completely the forefoot zone and backfoot zone.
  • ventilation holes 15 are open through the sole 1 in order to extend to the bottom of the second portion 11 of the incisions 8.
  • the ventilation holes 15 extend through the sole 1 from a surface 5A opposite the tread surface 5, until they extend to the bottom of the second portion 11.
  • the sole 1 comprises a lightening area 20 which is formed in the tread surface 5 with an extent in the toe-to-heel direction X in the form of a groove. Different forms of the lightening area 20 are illustrated in Figures 6A-C.
  • the lightening area 20 has a variable width, having a width which is greater at the midfoot zone 3.
  • that lightening area 20 has a curved extent with a flexion in the intermediate midfoot zone 3.
  • the lightening area 20 further has an increasing depth from the respective forefoot zone 2 and backfoot zone 4 towards the midfoot zone 3. The depth of that lightening area 20 can reach the depth of the second portion 11.
  • the form of the lightening area 20 allows promotion of the torsion movement of the sole which is derived from the natural dynamics of the foot during walking.
  • the characteristics of the lightening area 20 allow an improvement of the ventilation in the region thereof and the central arrangement and the greater opening thereof in the midfoot zone 3 prevent the presence thereof from
