AIR CIRCULATING SHOE USING THE LAW OF INERTIA

WIPO Patent Application WO/2010/030089

A2

The present invention relates to shoes including sneakers, dress shoes, hiking boots, and the like. The present invention is designed to prevent uncomfortable humid conditions and foot odor in shoes caused by the lack of adequate air circulation when the shoes are worn. Conventional methods for injecting and circulating air in shoes generate wind by rotating small rotary blades such as those of a fan mounted in the shoes by the force generated from a small motor. The air circulating shoe of the present invention is designed such that air is injected and circulated in the shoe by the force of inertia acting on the foot of a walking person, without using the power generated from an electrical motor or a battery. A rotary weight (1) rotates by the law of inertia at the moment when one foot of the walking person contacts the ground to make the speed '0 m/s'. The force generated from the rotation of the rotary weight (1) is transmitted to a rotary blade (4) by a power transmission device to rotate the rotary blade. Wind generated from the rotation of the rotary blade is supplied into the shoe through an air outlet port (5) and a connection pipe (7). The thus-provided air removes offensive odor and humidity within the shoe.
