Definitions

  • the present invention relates to a sole construction for footwear, which allows efficient air circulation in the shoe and thus directly at the foot of a wearer of the shoe at each step of the running movement.
  • shoes which are equipped in the sole with devices which promote the air circulation in the shoe, which reduces the internal moisture, whereby the foot comfort of the user is to be improved.
  • This known shoe type generally provides hollow connections, which are accommodated in the sole interior connected to one another.
  • a sole construction in which fresh air can be exchanged in the sole without mechanical parts with each step and forwarded directly to the foot.
  • a sole body is described in which a cavity is embedded, which extends continuously along the sole body and which is closed by an elastically deformable cover having openings, and in which the cavity through the openings with the shoe facing the outside of the Sole body is in communication and in which the cavity communicates with one or more first transverse passages, which open into openings in the lateral and / or rear surface / outer surface of the sole body, so that the cavity is placed in communication with the exterior of the sole body.
  • the efficiency of the air circulation and in particular the air inlet and the air outlet through membrane-covered openings in the sole construction, can not be considered as sufficiently satisfactory and thus can be improved.
  • This sole construction has a sole body comprising
  • Sole construction for a shoe comprising a sole body with a cavity comprising
  • an air pumping device which may for example be at least partially positioned in the cavity of the sole body
  • the air pump means is adapted to perform an air pumping function in response to a walking movement of a user of the shoe so as to alternately draw in air from the outside of the sole body via the at least one first air duct and introduce air into at least one of the air pump means via the at least one second air duct Pressing connecting part of the sole body, which may be different from the part in which the air pumping device is arranged; in the at least one first air duct, a first valve is arranged, which is designed such that it only lets air into the air pump device in the direction from outside the sole body; and or in the at least one second air guide, a second valve is arranged, which is designed such that it allows air only in the direction of the air pump device to the at least a part of the sole body passes.
  • air can be guided via the second air guide into a part of the sole body, which is different from the part in which the air pump device is arranged, or in the part in which the air pump device is located or in two or more parts or Chambers / cavities are performed.
  • the air pumping device may be provided in the heel region extending from the foot end to the joint region in the middle joint region and the ball region (forefoot region) extending from the foot front side to the joint region.
  • the second air duct may in this case be in the form of a channel in the sole body, it may also be provided only in the form of an outlet of the air pump device, in particular an air reservoir of the air pump device.
  • Outside air may be drawn in by the air pumping device depending on the walking phase, and the previously drawn in air may be discharged into a part of the sole construction in which the air pumping device is not located. If, during the appropriate walking phase, a user's foot does not bear on the air pumping device, it sucks in air from outside the sole structure via the corresponding air supply; when the foot is resting on it, it pumps the air into another part of the sole body from where it travels upwards along the Foot, for example, through openings of the sole body covering sock, is pressed for effective ventilation of the user's foot.
  • a sole construction which provides improved air circulation in a simple configuration, solely by movement during walking, without the need for significant enlargement over conventional sole constructions without air circulation.
  • the valves provided allow efficient control of the airflows over and beyond the air ducts into and out of the air pumping device.
  • the at least one first and / or the at least one second air duct may comprise a flexible hose and / or a covered duct or in each case consist of a flexible hose, for example of plastic. If a plurality of first and / or second air ducts are provided, they may all comprise one hose each or consist of, or some and not all of the air ducts each include or consist of a hose.
  • the air ducts can permanently and tightly in a simple and cost-effective manner, the air to the air pump device and from this for ventilation of at least a portion of the sole body and finally the shoe interior are continued.
  • the air pump device can be formed separately from the sole body as an independent entity and embedded or fastened in the sole body, in particular at least partially in the cavity of the sole body.
  • the air pump device may comprise a plastic pump reservoir. This is compressed when a user's foot rests on it, which squeezes air out of the plastic pump reservoir. If during walking the plastic pump reservoir is relieved again of the foot, it expands and pulls due to the previously formed negative pressure air through the at least one air duct with the first valve from the outside, for subsequent ventilation of the shoe interior and thus the foot of a User is freshly available.
  • the air pump device can be integrally formed in one piece with the plastic pump reservoir and the air ducts.

As a result, the pumping effect can possibly be improved.
  • this development requires a seal in the region of the underside (surface-contacting surface) of the sole body and of the air pump device. Therefore, it may be preferable to completely arrange the air pumping device within a cavity of the sole body closed at the bottom, whereby it is also exposed to a lower mechanical load.
  • the at least one first air duct, through which the air pump device draws in air may in particular be designed so that it does not communicate with the space outside of the sole body through the sole body.

  • a breathable and water-impermeable membrane for example with a GoreTex membrane
  • the GoreTex membrane is permanently waterproof, windproof and at the same time breathable and temperature-regulating.
  • the sole construction according to the invention furthermore comprises an apertured insole which covers the air pump device and the at least one part of the sole body. Through the openings of this insole, the air expelled from the air pumping device passes through the cavity of the sole into the shoe interior of a shoe comprising the inventive sole construction, where it serves to ventilate the foot of a wearer of the shoe.
