Breathable mesh cloth vamp capable of automatically eliminating shoe marks

Abstract

The invention discloses a breathable mesh cloth vamp capable of automatically eliminating shoe marks. A fluid component is arranged in the vamp; the fluid component is always in contact with the vamp;bending force generated when a vamp is bent can be absorbed, meanwhile, the fluid component is of a claw-shaped structure, the structure of the fluid component adapts to the stress condition of the vamp when the vamp is bent, the fluid component can well stretch and straighten out the vamp bent when the vamp is bent through expansion deformation, and therefore vamp creases at the position are actively repaired. Meanwhile, bifurcated parts and a main body part are in a communicated state, so that the bifurcated parts and the main body part can cope with complex vamp bending conditions, and thewear resistance and comfort of the vamps are further improved.

Description

technical field [0001] The invention relates to the field of footwear, in particular to a breathable mesh upper that can automatically eliminate shoe marks. Background technique [0002] People can't do without sneakers, sports shoes and other footwear in their daily life. The footwear includes two main elements: the upper and the sole structure. The foot extends into the space defined by the upper and the sole structure so that humans can walk on the road. The structure of human foot bones figure 1 As shown, five toes are included, and each toe is composed of several phalanges and a metatarsal, such as the big toe, which is composed of the distal phalanx 51, the proximal phalanx 52 and the first metatarsal 53. Similarly, the index toe , middle toe, ring toe and little toe are all composed of several phalanges and the second metatarsal bone 54, the third metatarsal bone 55, the fourth metatarsal bone 56 and the fifth metatarsal bone 57, the first cuneiform bone 58, the sec...

AI Technical Summary

Problems solved by technology

When people are walking or running, the proximal phalanges and metatarsals are repeatedly bent, which causes the upper to repeatedly bend and form creases. What’s more, degumming occurs at the joint between the upper and the sole, which seriously affects the The service life of footwear, at the same time, the curved upper will also squeeze the inner foot, affecting the comfort of people wearing shoes

Aiming at the problems of vamp creases and degumming of vamp and sole, some improved vamp structures also appeared in the prior art: such as patent document 1, which discloses a durable vamp, which divides the vamp into front upper, rear For the mid-top, the mesh elastic cloth upper is used as the connection surface between them. The front and rear mid-top are made of soft cowhide. The elastic properties make the front upper less prone to creases, but the upper structure is not integrally formed. Different materials need to be cut and assembled together. The processing is more complicated, and the mesh elastic cloth itself will also have cracks after being used for a long time. The crease does not fundamentally improve the crease problem; another example is Patent Document 2, which discloses a shoe upper structure, which divides the shoe upper into a first shoe upper member and a second shoe upper member that can move relatively. When the pedaling action upper bends, the front edge of the second upper member slides longitudinally on the first upper member, and the rear edge of the first upper member slides longitudinally under the second upper member, which improves the upper’s flexibility. However, since the first upper member and the second upper member can slide relative to each other, when the foot is bent, only the sole provides the anti-bending force. Although the bending force of the upper is changed, it is invisible The bending wear of the sole is increased. At the same time, because only the sole provides the anti-bending force, the foot is easily injured during running or other intense sports. Further, the upper is passively deformed by force and cannot be actively restored; another example is the patent Document 3, which discloses an upper structure of wear-resistant shoes, an elastic pad 16 is pasted on the outer surface of the upper, and a series of grooves 38 are arranged on the elastic pad, and the grooves are radially arranged. deformation to absorb the bending deformation of the upper, although it can prolong the service life of the upper, the elastic pad 16 that absorbs the bending deformation is only passively absorbing deformation force, and the radial center 30 determined by the groove 38 is determined A point, therefore, the shoe can only be suitable for feet of a specific size and length, and its versatility is poor
