Definitions

  • the present patent application refers to an outer sole for shoes provided with transpirant and waterproof properties.
  • moulded plastic soles with one or more holes capable of guaranteeing circulation of external air inside shoes have been available for long on the market to increase the user's comfort.
  • the holes used to introduce air are opened on the shoe walking surface.
  • the internal side of the holes is “sealed” with a membrane of known type that is transpirant and waterproof, since it permits the introduction of air and prevents the entrance of water and humidity.
  • shoes provided with outer soles impaired by the said drawback lose their transpiring properties in a short time.
  • the forced introduction of small stones inside the holes may tear the transpirant waterproof membrane that protects the internal side of the holes in the sole.
  • the cross-section of the ventilation holes has been reduced to minimum; however, although this reduces the risk of penetration of sharp micro-objects, it negatively reduces the air capacity of the holes and makes them more vulnerable of being suddenly clogged with soil or mud.
  • the purpose of the present invention is to innovate the said lo technology, with the specific aim of eliminating the aforementioned inconveniences.
  • the purpose of the present invention is to prevent air ventilation holes on the outer sole from getting filled with soil, small stones and different impurities; another purpose of the invention is to protect the internal transpirant waterproof membrane against the risk of getting damaged under the energetic interference action of hard impurities introduced through the holes.
  • a special section is provided on the moulded plastic outer sole (preferably in the centre of the front part of the foot) to guarantee reliable durable transpirant waterproof properties.
  • the special section of the outer sole of the invention can be obtained as an independent insert fixed at a later stage inside a suitable opening on the outer sole or as the result of a specific machining operation during production of the outer sole one-piece structure.
  • the special section of the outer sole is provided with multiple holes with circular cross-section for air introduction, as well as with the traditional transpirant waterproof membrane that covers the internal side of the holes on the sole.
  • the peculiarity of the invention consists in the fact that the holes contain corresponding small cylinders made of synthesized spherical bronze, in order to completely fill the entire cross-section and the entire height of the holes.
  • the cylinders are microsphered products obtained from spherical bronze powder.
  • Spherical bronze powder permits to obtain a machinable solid mass with good mechanical resistance and at the same time capable of being penetrated by air flow, by means of hot soldering process of the microspheres.
  • air delivery through these products changes according to the diameter of the powder microspheres and the thickness of the product obtained and, in general, is a linear function of load loss.
  • the real advantage of the said cylinders consists in the fact that, although they do not impair air circulation in favour the user's foot, they are able to prevent the risk of occlusion for the holes and the risk of damage for the internal membrane.
  • FIG. 1 is an axonometric view of the one-piece version of the outer sole of the invention
  • FIG. 2 is an exploded axonometric view of the version of the outer sole of the invention in which the special section is obtained separately and then inserted into a corresponding opening on the front part of the outer sole;
  • FIG. 3 is a cross-section with plane III-III of the special section of FIG. 2 .
  • the outer sole of the invention ( 1 ) is provided with a special transpirant waterproof section (Z) located on the front part of the foot.
  • the section (Z) is provided with multiple through holes ( 2 ), preferably with circular cross-section.
  • the internal side of the special section (Z) is entirely coated with a transpirant waterproof membrane ( 3 ) that, in this position, covers the external sides of the holes ( 2 ).
  • Each hole ( 2 ) exactly and permanently houses a cylinder ( 4 ) made of synthesized spherical bronze that allows air to penetrate the hole ( 2 ), while protecting the hole ( 2 ) against the risk of being clogged by impurities found on the ground that may eventually damage the membrane ( 3 ).
  • the invention may be realised according to two different constructive embodiments that are however absolutely equivalent in functional and conceptual terms.
  • the special section (Z) is originally incorporated into the one-piece structure of the outer sole.
  • the special section (Z 1 ) is obtained as a sort of independent moulded plastic plate ( 5 ), exactly mounted inside a suitable opening (F) on the corresponding version ( 10 ) of the outer sole of the invention.
  • the independent plate ( 5 ) is provided with suitable through holes ( 20 ) that exactly house the synthesized bronze cylinders ( 4 ) and is coated on the upper side with the traditional transpirant waterproof membrane ( 30 ).
  • the holes ( 2 , 20 ) on the special section (Z, Z 1 ) have a circular cross-section and, consequently, the synthesized bronze cylinders ( 4 ) have a corresponding cylindrical structure
  • the same holes ( 2 , 20 ) may also have a different cross-section and, consequently, the synthesized bronze cylinders ( 4 ) contained in the holes ( 2 , 20 ) may also have a different structure.
