Power-assisted shoe

Abstract

The invention relates to a power-assisted shoe, and aims to provide a power-assisted shoe that assists strong bending and saves effort. Technical solution: a power-assisted shoe with a sole with the front and rear ends tilted upwards, characterized in that a tensile layer that can bend and straighten is arranged in the sole. Beneficial effects: when a person stands, the upturned part of the sole falls down, the tensile layer is stretched vertically (from the toe to the heel) and straightened, the sole is compressed longitudinally, the hardness increases, and the downward bulge of the front half of the sole As a fulcrum, it acts as a leverage. When walking, the center of gravity moves forward, and the back of the sole rises, supporting the heel and giving a driving force. Then, as the heel lifts, the tensile layer relaxes, the sole softens, and the metatarsophalum flexes for less effort. The sole is still a special-shaped spring: when a person stands, the tensile layer is tightened, the sole is compressed longitudinally, and the elastic force is accumulated, and the heel is lifted to release the elastic force, which enhances the power-assisted effect; while the process of stepping on the sole and longitudinal compression of the sole is still shock-absorbing process, improving the softness and comfort.

Description

[0001] Technical field: [0002] The invention relates to a power-assisted shoe. [0003] Background technique: [0004] In order to improve the easy, labor-saving, soft and comfortable functions of footwear, people continue to develop power-assisted shoes. The existing power-assisted shoes (Chinese patent ZL200420063139.2) with the front and rear ends of the sole tilted upwards are power-assisted shoes made by utilizing the principle of leverage. Although the power-assisted shoes have been improved by patented technology several times, their inherent shortcomings have not been overcome: either the soles are made very hard and the power is strong, but the metatarsophalangeal parts are hard to bend and uncomfortable to wear; or the soles are made very soft and the metatarsal The toe is bent to save effort, but the power is weak, which is not much different from ordinary shoes. In short, the "contradiction between strong power and labor-saving bending" of the leverage principle...

Problems solved by technology

Although the power-assisted shoes have been improved by patented technology several times, their inherent shortcomings have not been overcome: either the soles are made very hard and the power is strong, but the metatarsophalangeal parts are hard to bend and uncomfortable to wear; or the soles are made very soft and the metatarsal The toe is bent to save effort, but the power is weak, which is not much different from ordinary shoes

In short, the "contradiction between strong power and labor-saving bending" of leverage-assisted shoes has not been resolved for a long time.
