Definitions

  • the present invention relates to a composite mid-sole. Disclosure of the Invention
  • the aim of the present invention is to provide a composite mid- so le that i s very l i ght and has hig h resilience .
  • Another object of the present invention is to provide a mid-so l e that has subst antial ly no sensitivity to hydrolysis .
  • Another object of the present invention is to provide a mid-sole that is flexible for customization and for the provision of variable rigidities and hardnesses .
  • Another object of the present invention is to provide a mid-sol e whose production can use conventional technologies and whose production costs and times are competitive with respect to conventional mid-soles .
  • a composite mid-sole characterized in that it comprises a shell , made of compact thermoplastic polymer, that is shaped so as to form one or more chambers filled with foamed material and/or with compressibl e or incompressibl e f l uid , a tread being associated with said one or more chambers in a downward region.
  • figure 1 is an orthographic projection view of the tread of a mid-sole according to the invention, in a first embodiment
  • figure 2 is a transverse sectional view of a mid-sole according to the invention, in a first embodiment
  • figure 3 is an orthographic projection view of the tread of a mid-sole according to the invention, in a second embodiment
  • figure 4 is a transverse sectional view of a mid-sole according to the invention, in a second embodiment
  • figure 5 is a transverse sectional view of a mid-sole according to the invention, in a third embodiment
  • figure 6 is a transverse sectional view of a mid-sole according to the invention, in a fourth embodiment.
  • a composite mid-sole according to the invention is generally designated by the reference numeral 10 in a first embodiment.
  • the composite mid-sole 10 comprises a shell 11 that is shaped so as to form a single chamber 12 that is filled with foamed material, such as two-component foamed polyurethane or other material having equivalent characteristics.
  • the chamber 12 In a downward region, the chamber 12 is closed by a tread 13 that in this case is made of rubber.
  • a composite mid-sole according to the invention is generally designated by the reference numeral 100 in a second embodiment.
  • the composite mid-sole 100 in th ⁇ s second embodiment, comprises a shell 101 that is shaped so as to form a plurality of chambers 102 of different sizes.
  • All the chambers 102 are closed, in a downward region, by a tread 103, which is made of rubber in this case, and are filled with foamed material, such as two-component foamed polyurethane, or another material having equivalent characteristics, or with a compressible or incompressible fluid, for example air or gas.
  • foamed material such as two-component foamed polyurethane, or another material having equivalent characteristics, or with a compressible or incompressible fluid, for example air or gas.
  • the variation in the dimensions of the chambers 102 and their filling method provide, with extreme flexibility, the possibility of setting the ideal rigidity for each region of the mid-sole.
  • a composite mid-sole according to the invention is generally designated by the reference numeral 200 in a third embodiment; the composite mid-sole 200 comprises, in this case, a shell 201 that is shaped so as to form a plurality of chambers 202 of various sizes, all filled with a foamed material such as two-component foamed polyurethane or other material having equivalent characteristics. All the chambers 202 are closed in a downward region by a rubber tread 203.
  • some chambers 202 (in this case, those related to the inner edge of the composite mid- sole 200) have a wall 204 that is thicker than the other walls, designated by the reference numeral 205, that form the other chambers 202.
  • a composite mid-sole according to the invention is generally designated by the reference numeral 300 in a fourth embodiment.
  • the composite mid-sole 300 in this case, comprises a shell 301 that is shaped so as to form a plurality of chambers 302 of various sizes, all filled with foamed material, such as two-component foamed polyurethane or other material having equivalent characteristics.
  • foamed material such as two-component foamed polyurethane or other material having equivalent characteristics.
  • All the chambers 302, in this fourth embodiment, are closed in their downward region by a common bottom 303 that is a monolithic part of said shell 301.
  • a rubber tread 304 is associated with the common bottom 303.
  • the present invention has achieved the intended aim and objects; in particular, it should be noted that the composite mid-sole according to the invention, in its various embodiments, by virtue of the foamed filling material or of the fluid, has a very light weight without sacrificing high resilience in view of its cellular structure. Furthermore, the materials and the structure of the mid-sole according to the invention ensure that said mid- sole has substantially no permanent deformation and also substantially no sensitivity to hydrolysis.
  • the chamber structure allows to customize rigidities in various points of the mid-sole.
  • the present invention is susceptible of modifications and variations, all of which are within the scope of the inventive concept.
  • the materials and the dimensions may be any according to the requirements.
