Definitions

  • This invention relates to a footwear element of rigid or semi-rigid behaviour, in accordance with the introduction to the main claim.
  • the sole unit must behave rigidly or at least semi-rigidly. This is for example the case in mountain shoes or boots, cycle shoes and boots for roller skates (both of traditional type and with in-line wheels), or in footwear used for certain athletics specialities.
  • This sole unit behaviour is required in order to achieve better foot support and/or to enable the user or athlete to transfer the greatest possible force to the ground or to the vehicle on which he moves (for example a bicycle), in order to achieve improved performance.
  • the sole unit (traditionally of leather or rubber, or of rubber and/or synthetic polymer mixtures)
  • two different methods are used, namely by inserting into the shoe vamp an insole constructed of more rigid materials than those used for the sole unit, such as wood, leather, cellulose conglomerates (such as that known by the commercial name of Texon), or of synthetic polyurethane resins, polypropylene, nylon or the like, or by metal blade or bar inserts; or by using rigid materials for the sole unit itself, such as leather, wood or synthetic resins of the aforesaid type.
  • the first method (insole) is used for example for mountain shoes or boots, and the second method for example for clogs.
  • Footwear has recently appeared on the market having the sole unit or insole (and in particular the whole or part of the sole unit) constructed of composite materials combining fabrics or fibres of light materials having a high elastic modulus (such as carbon, aramid, glass or synthetic resin fibres) embedded in a resin acting as a binder.
  • a high elastic modulus such as carbon, aramid, glass or synthetic resin fibres
  • Such solutions and constructional methods result in components (soles or insoles) having a considerable rigidity/weight ratio, making them advantageous over components obtained by the two aforesaid methods.
  • these components have a higher cost than that achieved by the other said known methods. This derives from the high cost of certain fibres (such as carbon fibres) and of the production process, which is usually slower and more delicate than those involved in the production of components constructed only of synthetic resins or by the other aforesaid known methods.
  • An object of this invention is to provide a footwear element of rigid or semi-rigid behaviour for use in footwear as a sole unit or part of the sole unit or as an insole which, although providing the footwear with the required rigidity, is of very low constructional cost.
  • FIGS. 1 and 2 show an element 1 for footwear such as a mountain boot 2 or a cycle shoe 3, said element being arranged to stiffen a lower part 4 of said footwear, which comprises a vamp 7 associated with said part 4.
  • this lower part 4 comprises a sole unit 8 of rubber or similar material, on which the rigid or semi-rigid element 1 is positioned and fixed to act as an insole.
  • a damping intersole 9 of expanded polyurethane or expanded ethylvinylacetate (EVA).
  • EVA expanded ethylvinylacetate
  • the element 1 stiffens the part 4, and is fixed to the sole unit by gluing or the like.
  • the element 1 acts as the actual sole unit, and is joined to the vamp in the usual manner, for example by gluing.
  • the removable insole 10 is placed on the element 1 as in the footwear embodiment of Figures 1 and 2, added pieces of rubber 11 (or other like material) possibly being applied externally to the lower side of said element and fixed to this element in known manner, for example by gluing.
  • the element 1 is of layered type and comprises (see Figures 6A, 6B and 6C) three layers mutually superposed to form a one-piece sandwich.
  • the outer layers 13 and 14 are of a material having greater rigidity than the inner layer 15, the thickness of this latter being however greater than the individual layers 13 and 14.
  • the layers 13 and 14 (connected together laterally, at the edges or side walls 26 and 27 of the element 1, so as to enclose the layer 15 within them), are constructed of the same material, and in particular of artificial plastic or synthetic resin, or of nylon, polyurethane or polypropylene, or of composite material comprising synthetic resins and fabrics or fibres of carbon aramid, glass or other synthetic resins.
  • the layer 15, acting as the core of the layered structure 1A of the element 1, is constructed of a lighter material than the constituent material of the layers 13 and 14, such as artificial plastic foam or expanded resin (shown in Figure 6C), cellular materials of natural origin (such as light wood, shown in Figure 6A), or cavity-containing materials (Figure 6B) formed from touching cylindrical plastic elements 17 of equal or different circular cross-sections or of elliptical or polygonal cross-sections.
  • the elements 17 can be solid or hollow and define a honeycomb structure.
  • the various layers 13, 14 and 15 are joined together to form a one-piece structure 1A which cannot be separated into its various components.
  • the various components (layers) of the structure 1A are integrated in various ways: for example by polymerizing the epoxy resin with which the layers 13 and 14 have been preimpregnated, if thermoplastic materials are used; by softening the resin defining the core ( Figure 6C) until fusion, if thermoplastic materials are used for the layers 13 and 14; or by gluing the various layers together, this method being suitable whether the layers 13 and 14 are of thermosetting or thermoplastic materials.
  • a stiffening element 1 obtained in accordance with the invention is of lower cost than a known equal-thickness similar element obtained from composite materials, however its rigidity is comparable to these.
  • the element 1 is very light in weight compared with analogous known elements, while having at least a comparable rigidity to these layer. It is preferably used along the entire extent of the lower part 4 of the footwear 2 or 3 (ie along the entire foot of the user) and can comprise a plurality of portions of constant or variable cross-section 20, 21, 22 ( Figure 5 but again in layer form) with different flexibilities on the basis of their position relative to the user's foot (for example with greater flexibility at the forefoot).
  • the element 1 in one piece (but again of layer form) with different thicknesses, decreasing towards the front end 23 of the element 1 (with reference to the foot shape of the user wearing the footwear 2 or 3), as shown in Figures 4 and 5.
  • the thickness of the element 1 can be greater in the forefoot portion or region 20 and decrease towards the heel region 22, or be constant along its entire longitudinal axis A, as shown in Figure 1.
  • the cross-section of the element 1 can be constant ( Figure 7A), variable (Figure 7B) and decreasing towards its lateral edges 26 and 27, or comprise ribs 28 (Figure 7C) for further stiffening.
  • the element 1 can comprise differently ribbed portions (as in the embodiment of Figure 8 to 8C).
  • the front portion or forefoot 20 can comprise at least one pair of lower parallel ribs 33, with no ribs on the arch portion, and with the heel or ankle portion 22 comprising only one central rib 34.
  • At least the lower part can be clad with a film 36 of thermoplastic material (such as that known by the commercial name of PEBAX) able to protect that element.
  • a film 36 of thermoplastic material such as that known by the commercial name of PEBAX
  • the film 36 can also cover at least a portion of the upper part of the insert, in its forefoot region 20, and in that case also wrap the lateral part of the corresponding element 1 (see Figure 9A).
  • This film is associated with the element 1 for example during the polymerization of the aforedescribed resin, or otherwise during the assembly (moulding) of the various portions of said element.
  • a layer 44 of fibrous material such as felt or non-woven fabric, can also be associated with the underside of the element 1 (see Figures 9 to 9C). This facilitates the subsequent fixing of this element into the sole unit or onto the intersole (or equivalent element) when this element is finally positioned, as a foot support, within the relative footwear (for example the boot 2).
