Definitions

  • the present invention relates to a device that allows internal ventilation of shoes.
  • a device for the internal ventilation of shoes as defined in the preamble of the appended claim 1 is disclosed in GB-A-2 247 391.
  • shoes are known that are predominantly used for gymnastics and have an upper made of a material that allows a limited flow of air through it; however, these solutions have some drawbacks: on one hand it is not possible to achieve optimum ventilation of the inside of the shoe, thus again producing non-optimum conditions for the foot inside said shoe.
  • said material can allow water infiltrations in case of rain, further aggravating the condition for the foot.
  • the aim of the present invention is therefore to solve the above described technical problems, eliminating the drawbacks of the mentioned known art and thus providing a device that allows to achieve optimum internal ventilation of a shoe and particularly allows to expel the moisture present inside it.
  • an important object is to provide a device that allows the foot to be placed in an environment that facilitates its optimum transpiration.
  • Another important object is to provide a device that in particular allows optimum ventilation in the region of the sole of the foot.
  • a further important object is to provide a device that allows to drain any water accumulated inside the shoe.
  • Another important object is to provide a device that is reliable and safe in use and can be easily applied at a part of the shoe.
  • Another object is to provide a device that has modest production costs and can be manufactured with conventional known equipment.
  • the reference numeral 1 designates a device for the internal ventilation of a shoe 2 having a sole 3 with which an upper 4 is associated.
  • the device has at least one air bag, designated by the reference numeral 5, which is arranged at the inner lateral surface 6 of the sole 3 in a suitable cavity 7 formed thereon.
  • said air bag 5 is thus essentially U-shaped and its arms 8a and 8b are arranged at the front region 9 of the shoe 2 that lies below the front central part of the user's foot.
  • the air bag 5 is connected to at least one first intake valve 10 which is directed toward an optional overlying insole 11 that has appropriate holes 12; said first valve 10 is preferably associated where the arm 8b and the base 13 of said air bag join.
  • Said air bag is furthermore connected, by means of a suitable first duct 14 located at the connection between the arm 8a and the base 13, to a second air discharge valve 15 which is associated at the perimetric tang or edge 16 of the sole 3, preferably in the heel region 17.
  • the air bag 5 can have, as shown in figure 4, a variously curved shape so as to affect the entire region of the sole of the foot and so that it can accordingly be associated with a support shaped like an insole.
  • the air bag 5 can have, at the front region 9, a main chamber 18 which is connected to a second duct 19 located approximately at the plantar arch region of the foot and extending along the entire perimetric region of the foot.
  • Suitable third ducts 20a and 20b furthermore extend from said second duct 19 starting from the ends of the tip and of the heel and are arranged approximately longitudinally with respect to the support.
  • the air bag 5 is thus associated with a support that is shaped like an insole so that it can be placed at the inner lateral surface 6 of the sole.
  • the air bag 5 has a first intake valve 10, located at the main chamber 18, for aspirating air from the inside of the shoe, and a first duct 14 for connection to a second discharge valve 15 which is associable at the perimetric ridge of the sole, preferably in the lateral region of the plantar arch.
  • the appropriately perforated insole 11 is then optionally placed on top.
  • While walking there is a step during which the air bag 5 is compressed, expelling the air contained inside it by means of the second valve 15, and then a subsequent step during which air is drawn inside the air bag 5 through the first valve 10 that is connected to the inside of the shoe.
  • the solution shown in figure 4 also achieves the intended aim and objects, and in this case it is also possible to use multiple first intake valves, locating them in the desired points so as to produce the best air flow.
