Title:
WIND GENERATOR FOR AN AIR-CIRCULATING SHOE USING THE LAW OF INERTIA
Document Type and Number:
WIPO Patent Application WO/2010/056073
Kind Code:
A2
Abstract:
The present invention relates to a shoe in which a rotary blade rotates solely by the inertial force generated by the foot and the shoe during walking without using a power source such as a motor or a battery, in order to inject air into the shoe, and thus discharge sweat from the inside of the shoe and reduce foot odor in the shoe. The present invention comprises a reciprocating motion generator (4) constituted by a reciprocating weight (2) with planar teeth (1), and a spring (3), a rotary blade (5), and a toothed wheel (7) attached with a reverse rotation prevention fin (8). The reciprocating weight (2) with the planar teeth (1), mounted on a left shoe, moves in the left direction in the figure at the moment when the sole of the left foot walking forwards contacts the ground to make the speed '0 m/s'. At this time, the tooth wheel (7) attached to the rotary blade (5) moves in a clockwise direction, but the rotary blade (5) does not move thanks to the reverse rotation prevention fin (8). The toothed wheel (7) attached to the rotary blade (5) rotates in a counterclockwise direction when the reciprocating weight (2) with the planar teeth (1) returns to the right side by the force of the spring (3). At this time, the reverse rotation prevention fin (8) is caught by a rotary blade groove (6) to rotate the rotary blade (5) in a counterclockwise direction. Wind generated by the rotary blade is supplied to the inside of the shoe via an air outlet port (10) and a connection pipe (11). Air thus supplied to the inside of the shoe circulates through an air circulation path (8) formed inside of the shoe to remove offensive odor and sweat from the inside of the shoe.
