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 sole construction for a shoe having an upper sole portion having channels; a lower outsole part; and an air pumping device connected to the channels and formed substantially in the upper sole portion.
- the terms 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.
- Said 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 foot of the user 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 joint region in the middle joint region and / or the ball region (forefoot region) extending from the foot front side to the joint region.
- the feature that the air pumping device is formed substantially in the upper sole part means that the air pumping device is at least more than 50% in the upper sole part (and less than 50% in the lower sole part), even if they are collectively due to cooperation of the upper sole part and the lower sole part may be formed.
- 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 pumping effect can be further assisted by the fact 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 part is larger than that provided by the lower sole part in the formation of the cavity serving as the air pump means.
- the cavity can be designed to be more than 80%, in particular more than 90%, in particular more than 95%, in the upper sole part.
- 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 can comprise a plastic reservoir as a separate 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 be educated. 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.

- 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.
