Definitions

  • the present invention refers to an improved type of ventilated and cushioning insole for general purpose footwear applications.
  • Insoles for use in footwear applications are generally known in the art under various denominations and, in particular, also under the name of inner sole, foot pad or the like; the present invention relates to that portion of a footwear which is integrated therewith, and which the foot lies or rests upon, or that accessory item which is inserted in the footwear , normally upon the lower portion of the vamp, and which the foot is caused to rest upon.
  • the present invention relates to that portion of a footwear which may be either removable or not, and which may be either an integral part of the footwear or not, on which the foot rests.
  • an important function in sports footwear lies in effectively protecting the foot against running stresses; in those sporting activities, such as for instance tennis, in which the foot is required to continuously or repeatedly spring, hop or bound under stresses that are certainly violent, although generally restrained within generally short periods of time, the need arises for an insole to be provided which is capable, jointly with the rest of the footwear, of ensuring a marked cushioning effect, and a good lateral foot-holding capacity, under a continuous aeration of the foot, in such a manner as to prevent the foot from being subject to excessively violent stresses, as well as to ensure that the foot is cooled continuously and is capable of effectively dissipate its own sweat.
  • such an insole shall be capable of being provided in the form of an accessory item that can be inserted or removed at will in or from the footwear, or shall also be capable of being applied in a stable a firm manner in the footwear during the manufacturing process thereof.
  • said insole shall be capable of being manufactured in a simple, low-cost manner with the use of readily available materials and techniques.
  • An insole according to the present invention comprises, from top to bottom, a first layer 1 of a soft, moderately elastic material, such as preferably latex or the like, provided with properties that allow for a passage of air therethrough.
  • a soft, moderately elastic material such as preferably latex or the like
  • a second layer 2 made of a reticular compound, which is fully permeable to the passage of air and featuring preferably a honeycomb structure.
  • the most suitable material to this purpose is a braided structure, at least 0.6 mm in thickness, of non-contaminable or non-degradable plastic material, such as for instance polyamide compounds.
  • this second layer lies in the marked elasticity thereof and, in particular, the capability thereof to act as an "air lung", i.e. an air reservoir; it therefore must be capable of recovering the normal thickness thereof when it is not being compressed, whereas, when it is compressed, its thickness must be capable of being reduced without any appreciable effort in a significant manner as compared with the initial thickness.
  • the above-mentioned two layers are contained in a shell acting as a sheath and formed by a top layer 3 that may be of natural leather, plastics or fabrics, whereas the bottom layer 4 is made of a material that must be adequately strong, but does not necessarily feature any special or particularly required property, such as cardboard that may be blended with other reinforcing fibres to a lesser or greater extent, having a thickness of anywhere between approximately 0.9 and 1.0 mm.
  • the four matingly fitting layers are sealed together by some suitable sealing means provided all along the outer periphery thereof, preferably with a welding seam or other known means.
  • this assembly is perforated with a plurality of through-channels 5 which in particular perforate, i.e. extend through the two outer layers of the assembly.
  • the layer 1, which is formed of a porous material is squeezed and, as a result, the air contained therein moves away to mix with the air from the layer 2 to be ultimately ejected jointly therewith.
  • the cushioning effect is ensured mainly by the layer 2, since the layer 1, although being elastic, has above all the function of creating a constantly soft barrier under the foot, so as to isolate it from the hardnesses of the layer 2 therebelow.
  • the air within the insole is caused to circulate and is partially exchanged with the outside air, thereby enabling the above-described beneficial effects to be obtained.
  • the layer 2 goes on acting as a "spring", by absorbing all possible strains or excessive loads imposed to the foot owing exactly to the fact that such a spring extends with quite an appreciable thickness all over the bottom surface of the foot; in fact, should there be a particularly localized strain or load, a full compression of the layer 2 in the concerned zone occurs, while all other zones remain uncompressed.
  • the layer 1, owing to its being porous, may be impregnated with substances, such as for instance activated carbon, which prove valuable in maintaining the hollow space, i.e. gap within the insole in the best possible hygienical conditions in that, by fighting the growth of fungi and bacteria, oppose bacterial fermentation processes and the formation of fungi within the footwear.
  • substances such as for instance activated carbon
  • footwear which are since the beginning, i.e. their manufacturing, and in a stable manner equipped with the above-described type of insole, so as to enable the afore illustrated advantages and benefits to be obtained starting from the first time that such footwear are used.
  • the present invention provides the best conditions and advantages since it will be possible for the nature and the thickness of the various components to be finely tuned to the actual requirements of such uses, so as to maximize the advantages that are to be achieved.
