Definitions

  • the invention relates to a shoe including a sport comprising a shaft surmounting an outer soleing made according to a laminated profile in several layers fulfilling distinct functions.
  • Such a shoe construction and especially its sole provides a modular concept of sole in which each layer performs very distinct functions, the modulation of which provides shoes to meet the different needs to be filled according to the particular sport to the practice of which the shoe is intended.
  • the FR 2,777,429 also discloses a shoe provided with a three-layered sole in which the intermediate layer, called “nerve”, has transverse recesses of particular shape intended to provide a stable and stable support of the shoe, and in particular to provide a support in ""edgecatch", that is to say, increased grip in the land in reverse.
  • the object of the present invention is to provide an improvement to the outer sole constructions of the type mentioned above.
  • An object of the present invention is in particular to provide a sole construction which provides a stimulus effect.
  • a stimulus effect is interesting for use in running, but also depending on the case for use walk or otherwise.
  • the shoe according to the invention which is of the type comprising a rod surmounting an outer sole, comprising from the bottom upwards an outer sole having adhesion characteristics, an insert having controlled characteristics of rigidity, and a top layer of comfort damping material and / or viscoelastic, in that the insert has a front portion up along the upper comfort layer.
  • the insert comes by its front part to compress, or prevent deformation, the comfort layer in the phases of flexion of the foot, because of the additional energy is stored by the layer comfort, this energy being restored during the next phase of relaxation of the foot.
  • the rise of the insert thus makes it possible to obtain, by compressing the comfort layer, an additional stimulus effect, which is added to the stimulus effect associated with the more or less rigid material constituting said insert.
  • the figure 1 represents a shoe 1 according to the invention consisting of a rod 10 and an outer sole 20 surmounted by said rod.
  • the shoe 1 is a shoe intended for running, particularly on uneven ground, and therefore has a relatively low shaft 10 and an outer sole 20 that dampens but is nevertheless low enough so as not to damage the stability of the foot. on uneven ground or on slopes.
  • the rod 10 is provided, in a manner known per se, with a lacing system 11 and a front end 12.
  • the sole assembly 20 comprises, in a manner known per se, an outsole 21 or contact layer of adherent and wear-resistant material such as rubber, an insert 30 constituted in this case by two parts respectively before 33 and rear 31 , and a so-called upper comfort layer 22 which is of damping material such as EVA.
  • This comfort layer 22 may also be made of a viscoelastic material such as elastomer, PU foam.
  • the insert 30 is, in the example shown, consisting of two respectively rear and front portions 31 and 33, but it could obviously be in one part.
  • this rear portion 31 of the insert is not described in detail.
  • this rear portion 31 has a vault shape extending as far as the edges of the outer sole 21 and defining tabs 32 surrounding this outer sole as described in FIG. EP 1 447 019 , this construction being advantageous for hanging on non-flat terrain.
  • a shim 50 of damping material such as EVA, PU foam is interposed between the rear portion 31 of the insert and the contact layer 21 (cf. figure 3 ), this shim 50 could be removed so as to have a direct contact of 31 and 21.
  • this rear portion 31 of the insert could have a completely different shape / construction depending on the desired result and / or type of shoe.
  • the insert 30 is preferably made of an elastically deformable material, that is to say a relatively rigid material and having controlled torsional and flexural stiffness characteristics, and having a Young's modulus E greater than 40 MPa.
  • Composite materials for example based on fiberglass / carbon and synthetic resin having a Young's modulus E greater than 50 MPa are also conceivable.
  • the thickness will be a function of the desired degree of elasticity and the Young's modulus of the selected material.
  • the two insert parts 30, 31 may have similar or different stiffnesses, in the latter case the insert portion 30 may be chosen steeper than the insert portion 31, or vice versa.
  • the rear portion 31 of the insert is extended forward by two V-shaped branches 32a deviating and having a reduced thickness relative to the remainder of said rear portion 31.
  • the front portion 33 of the insert also has two horizontal branches 34 having slightly divergent shapes corresponding to those of the branches 32a of the rear portion 31 of the insert. These two branches 34 extend forwards by a vertical rise 35 which covers the upper comfort layer 22 and the front end 12 of the rod 10 (cf. figure 1 ).
  • the front lift 35 of the insert extends only at the end of the boot, ie not on the sides thereof. Depending on the case, it can also go up on the sides.
  • the insert 30 in two parts 31, 33 reduces the number of molds necessary for the realization thereof. Indeed by overlapping of the branches 32a and 34 respectively rear and front portions of the insert, one can use the same type of insert for several shoe sizes. It suffices to have a recovery function of the length of the shoe and to proceed to the bonding.
  • the two insert parts 30, 31 can also be connected together without overlapping or simply butted.
  • the branches 34 also have a reduced thickness in their area 34a of overlap with the branches 32a, so as to avoid any discontinuity in the insert. Finally, the branches 34 have in the horizontal zone an enlargement 34b can be visible on the sides of the sole after the shoe mounted.
  • the vertical lift 35 has, in the example shown, the shape of an inverted vertical U connecting the two horizontal branches 34.
  • FIGS. 1 to 4 illustrate a first embodiment in which a first subset comfort layer 22-rear portion 31 of the insert is made by gluing (cf. figure 3 ).
  • This first subassembly is assembled by gluing to the rod 10 provided with a front end 12 and a strobel sole 13, said rod being mounted on a shape (not shown in the drawing).
  • the front portion 33 of the insert is then assembled, by gluing, both to the stem and to the first subset of the comfort layer 22 - rear portion 31 of the insert, as shown in FIG. figure 4 .
  • the front portion 35 of the portion of the front insert 33 traps both the comfort layer 22 and the rod 10.
  • the reinforcing front portion 33 comes by its ascent before forcing both the layer of damping material 22 and the rod 10.
  • the material constituting the comfort layer 22 is constrained and prevented from expanding, thereby the end of the bending movement, said material of this layer 22 will tend to return to its original shape and release an energy that will be added to that restored by the elastic material constituting the front portion 33 of the insert.
  • the stiffness of the rod can also affect the energy release.
  • the shoe has exactly the same elements, the only difference residing in the assembly mode thereof.
  • front portion 33 of the insert is a separate subassembly with the front end 12 of the upper of the shoe.
  • This subassembly can be made by bonding these two elements or by overmolding the front end 12 on the front portion of the insert 33, or vice versa.
  • the second subassembly 12-33 is positioned and assembled on the rod by gluing and then the third subassembly is put in place and glued between the rod and the second subassembly as indicated by the arrow F on the figure 6 .
  • This second method of assembly has the advantage that the positioning of the insert front portion 33 relative to the rod 10 and to the entire back 22-partoe comfort layer 31 insert is easier.
