Power-assisted shoe

Abstract

The invention relates to a power-assisted shoe, and aims to provide a power-assisted shoe, which has high assisting power and can be bent in a labor-saving way. According to the technical scheme, the power-assisted shoe is provided with a shoe sole of which the front and back ends tilt upwards. The power-assisted shoe is characterized in that an anti-tensile layer capable of bending and straightening is arranged in the shoe sole. The power-assisted shoe has the beneficial effects that when a person stands, the front and back tilting parts of the shoe sole descend, the anti-tensile layer is tensioned and straightened along the longitudinal direction (from a shoe toe to the shoe sole), the shoe sole is compressed longitudinally with the hardness being increased, and a downward bump of a front half part of the shoe sole is taken as a support point, thereby playing a role as a lever. During walking, the gravity is shifted forwards, and the back part of shoe sole tilts upwards for supporting the shoe heel, so that thrusting force is provided. Afterwards, the anti-tensile layer is released along with the lifting of the heel, the shoe sole is softened, and a toe part is bent in a labor-saving way. The shoe sole is a deformed spring: when the person stands, the anti-tensile layer is tensioned, the shoe sole is compressed longitudinally for accumulating elastic force, and the elastic force is released by lifting the heel, so that the power-assisting effect is enhanced; a process of treading the shoe sole and compressing the shoe sole in the longitudinal direction is a damping process, so that the softness and comfort are improved.

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.
