idportion footwear forced ventilator // 2352229
FIELD: shoe industry.SUBSTANCE: invention refers to shoe industry, particularly can be used for forced internal footwear ventilation due to atmospheric air injection through footwear toes. The atmospheric air is injected through horizontal elastic channeling arranged in the sole. The sole consists of at least three layers firmly interconnected. The centre contains soft and elastic material layer with horizontal elastic tubes. Elastic tubes or elastic channels are not interconnected. In walking the heel back interacts to the surface of the former, then sole and surface contact is shifted to the sole toes. Simultaneously the load is sequentially shifted from the heel to the sole toes. Under the gravity channels are deformed and blocked thus pushing the air through the channels from the heel to the footwear toes. Elastic tubes or elastic channels is small-diameter round or elliptic sectioned herewith the internal diameter does not exceed 1.5-2.0 mm. Pressure increase inside of the footwear causes air and water vapour exhaust through the natural cracks between a foot, internal surface of footwear top and toe material. It is repeated with each step, i.e. in walking horizontal channelling represents the pump which injects the atmospheric air to the footwear toe.EFFECT: improved footwear comfort and hygienic properties.2 dwg

ethod of forced shoe ventilation // 2348337
FIELD: household goods and personal effects.SUBSTANCE: atmospheric air is pumped through the system of horizontal elastic channels available in the shoe sole. They are placed in the cellular layer and do not interact with each other. While walking, the rear part of the leg heel interacts with the support surface of the front part. Then the sole contact with the surface moves to the toe part. At the same time, the load moves subsequently from heels to toe. The elastic channels of minor diameter of the cross section are deformed and blocked under the gravity effect. It helps to push air from hell to toe part of the show. The channel section diameter does not exceed 1.5-2.0 mm. Pressure is increased in the inner shoe volume resulting in air and water steam release through the natural slots between feet, inner surface of shoe top and toe material. The same action is repeated at each step, i.e. the system of elastic, horizontal channels is represented with a pump, which pumps atmospheric air into the toe part of the shoe.EFFECT: more comfortable shoes, improved hygienic properties due to atmospheric air pumping through the toe shoe part.2 dwg
