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 type of shoe suffers from lack of efficiency of air circulation in the shoe.
  • a boot with a rubber sole and a shaft is described.
  • the one-piece rubber sole has an upper sole portion with an air pumping means in the form of a lenticular cavity formed in a heel of the sole, and a lower sole portion.
  • a fresh air intake passage 16 is performed.
  • an air-circulated footwear having compressible chambers provided between an outsole and a comfort pad is described.
  • EP 2 218 348 A1 describes a sole construction in which air passes from outside through an air duct into an air chamber and an air passage.
  • a sole insert for air circulation is described.
  • upper, upper, etc. refer to positions farther from a substrate contacted by the sole construction when used in a shoe than positions referred to by terms such as below, lower, and so on.
  • first and second sole parts of the sole construction may be formed separately, but they may also form parts of an integrally formed sole body, so that they form an integral block.
  • air is sucked in from outside the shoe by the air pump device and distributed into the channels.
  • the air pump device is adapted to carry out an air pumping function in response to a walking movement of a user of the shoe with the sole construction according to the invention such that it alternately sucks in air through at least one air guide from outside the sole construction or the shoe when being relieved by the user's foot and, upon loading of the air pumping device by the user's foot, air is distributed throughout the channels in the shoe.
  • the air pumping device may be provided in the heel region extending from the foot end to the hinge region in the middle hinge region and / or the ball region (forefoot region) extending from the foot front to the hinge region.
  • the air pumping device substantially in the upper sole part is formed is that the air pumping device is formed at least more than 50% in the upper sole part (and less than 50% in the lower sole part), although it may be formed by cooperation of the upper sole part and the lower sole part.
  • this feature may state that the air pump device is formed in the upper sole part at least more than 80%, in particular more than 90%, in particular more than 95%.
  • At least the part of the upper sole part in which the air pump device is formed may be formed more elastically than the lower sole part. This more elastic training a pumping effect over the entire sole, ie from the heel on the joint to the bale can be achieved.
  • the part of the upper sole part, in which the air pump device is formed, more elastic than the lower sole part an efficient pumping action can be achieved.
  • this more resilient area is forced downwards (towards the tread) and thus can actuate the air pumping device to push air out of the air pumping device and through the channels.
  • the pumping effect is further assisted in that the lower outsole part on the outer running surface (which in the course of a walking movement is in contact with the ground on which a user of a shoe runs with the sole construction according to the invention) has a raised area in the area of the air pumping device, which is adapted to be pressed under load by the foot of a user in the direction of the upper sole part.
  • the raised area may be thinner than the remaining areas of the lower outsole part.
  • the air pump device is formed by a cavity substantially embedded in the upper sole part, or the air pump device is designed separately as an independent entity and is completely or partially embedded in a cavity of the upper sole part.
  • the volume fraction of the cavity formed in the upper sole portion is greater than that provided by the lower sole portion in the formation of the cavity functioning as the air pumping means.
  • the cavity can be formed to more than 80%, in particular more than 90%, in particular more than 95%, in the upper sole part be.
  • the air pump device is provided in the form of a cavity filled with an air-permeable elastic filling material.
  • the use of only one formed cavity as the air pumping device simplifies the manufacturing process, reduces the manufacturing cost and can increase the reliability and life of the air pumping device.
  • the use of a separately designed as an independent entity air pump device can improve the efficiency of air circulation.
  • the air pump device may comprise a plastic pump reservoir as an independent entity. 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 again relieved of the foot, it expands and, due to the negative pressure previously created, draws in air from the outside, which is freshly available for the subsequent ventilation of the shoe interior and hence the foot of a user.
  • the air pump device can be integrally formed in one piece with the plastic pump reservoir and the air ducts. The formation of the air pump device as a separate entity allows an independent of the sole construction or the sole body material selection and in particular material strength.
  • openings may be provided along the channels in the upper sole portion such that air passing through the channels passes through the openings to above the upper sole portion, i. into the interior of a shoe, which has the sole construction according to the invention, can get.
  • air pumping device under load from a user's foot, air is pumped through the channels and the openings provided therein for aeration of the foot into the shoe interior in which the foot is located.
  • hoses may also be provided by the air pumping device along the channels in which air flows from the air pumping device.
  • the hoses must have openings corresponding to those which may be provided in the upper sole part.
  • the hoses can be made of silicone, for example.
  • the upper sole part and the lower sole part can be separate may be formed or the upper sole portion and the lower sole portion may be integrally formed in one piece, so as an integral block.
  • the upper sole portion and the lower sole portion may be formed of different materials, or may be formed of the same material.
  • the sole structure can be formed around a separate, independently formed air pumping device, such that the upper sole part is more elastic (due to different thicknesses) than the lower sole part at least in the area of the air pumping device.
  • the sole construction is made here of an elastic material, for example by plastic injection.
  • the sole construction according to the invention can furthermore comprise plastic hoses which are arranged in the channels, wherein the plastic hoses have openings along their longitudinal axes and are in fluid communication with the air pump device.
  • outside air can be sucked in by the air pump device, depending on the walking phase, and the previously sucked air can be expelled into the channels. If in the appropriate walking phase the foot of a user does not load on the air pump device, this sucks air from outside the sole structure via the corresponding first air supply, when the foot loads on her, it pumps the air through the corresponding second air supply into the channels, from where they are pressed upwards to the foot of a user, for example through openings provided in the channels at the top, 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 air flows through the air ducts into and out of the air pump device.
