Detailed Description

The following describes a mode for carrying out the present invention with reference to the drawings.

As shown in fig. 2, when a person walks or runs, the person needs to perform a pedaling action of the foot, during the pedaling action of the foot, the upper of the shoe is bent, the foot is bent at the metatarsophalangeal joint formed by the proximal phalanx and the metatarsal bone, and the upper of the shoe is further extruded and deformed, wherein, the instep can generate a extrusion force F to the vamp, and meanwhile, the extrusion force generated by the deformation of the vamp can be applied between the vamps, so that the stress from the upper border of the vamp to the instep is complex, the deformation of the vamp is not specially regular, the bending crease is in an irregular arc structure, as shown in figure 2, however, in the area between the instep contact surface and the sole on the side of the vamp, because no foot directly contacts the vamp, therefore, the crease in the area is a plurality of creases in a linear structure, and therefore, the creases on the vamp are formed by the creases in an irregular arc structure and the creases in the linear structure together.

As shown in fig. 3 to 4, the shoe upper of the present invention includes an inner shoe upper 18, an outer shoe upper 19, and a fluid member 5 disposed between the inner shoe upper 18 and the outer shoe upper 19, the inner shoe upper 18 and the outer shoe upper 19 together constitute a shoe upper 3, a sole 2 is fixedly attached to a lower portion of the shoe upper 3, the shoe upper 3 covers a foot 1 of a wearer, a tongue 6 is provided on an upper portion of the shoe upper 3, an upper boundary 16 is formed at an edge of a receiving space formed by the shoe upper 3 for receiving the tongue 6, the fluid member 5 includes a main body portion 11 and at least two branch portions 12, which are integrally formed in a claw-shaped structure, the main body portion 11 is located at an upper end portion of the shoe upper 3, and the upper edge of the main body portion 11 is parallel to the shoe upper boundary 16, the lower end of the main body portion 11 is connected with the at least two branch portions 12, which are illustrated as three branch portions 12, each branch portion 12 is formed in a bar-, the point O falls between the upper edge of the main body portion 11 and the upper boundary 16, preferably at the upper edge of the main body portion 11. This kind of mode of arrangement for the branching portion 12 of bar structure can be fine adaptation vamp the crease that produces when buckling, and the setting of the fluidic component 5 of claw type structure for upper portion main part 11 can adapt to the bending force of absorbing vamp border to instep region, and branching portion 12 just is used for absorbing the bending force of the linear structure of instep contact surface to the region between the sole.

Preferably, the angles between adjacent bifurcation body axes 9 are all equal. The distance L between the point O and the shoe top is adapted to the distance S between the big toe of the foot 1 and the metatarsophalangeal joint, preferably 0.9S & ltoreq L & ltoreq 1.1S. Preferably, the lower end of the crotch 12 extends to the sole 2, so that the fluid member 5 can flatten the bending structure of the vamp at the connection position of the vamp and the sole, and prevent the vamp from being degummed.

As shown in fig. 4, the fluid member 5 includes an inner edge 13, an outer edge 14, and a fluid 15 disposed inside the inner edge 13 and the outer edge 14, and the fluid 15 may be a gas, a liquid, a gel, or the like. The inner edge 13 and the outer edge 14 are made of sealing film materials, such as polyurethane films, and the creases are repaired only by utilizing the shape deformation of the fluid component 5; further preferably, in order to enhance the effect, the inner edge 13 and the outer edge 14 are made of materials with different elasticity, the inner edge does not expand or contract with more or less fluid, the outer edge 14 expands or contracts with more or less fluid, the inner edge is made of polyurethane film, the outer edge is made of rubber type or the like, and the inner edge 13 and the outer edge 14 can be sealed by heat sealing or RF sealing. Thus, when the shoe upper is bent, the instep presses the fluid in the main body part 11, so that the fluid flows towards the crotch part 12, the outer edge 14 expands to a certain extent due to the increase of the fluid, the expanded outer edge 14 can actively smooth the crease of the shoe upper, a larger unfolding space is provided for the bent shoe upper, the crease is actively repaired through the fluid, and the traditional mode that the crease can only be passively absorbed is changed.

Preferably, interior limit 13 is for leveling the structure, and outside 14 is the protruding structure of arc, and the laminating foot that interior limit that levels the structure can be fine can not make the foot take place the discomfort, and the crease on external vamp 19 that the outside of the protruding structure of arc can be fine is restoreed, prolongs the life of shoes, further increases the wearability.

As shown in fig. 5, in another variant of the fluid component 5, a connecting transverse edge 17 is provided between the two branches 12, taking into account the relative rotation between the branches 12, i.e. the rotation between the branch body axes 9 along the point O, so that the relative rotation between the two branches 12 can take place without damaging the fluid component 5. Further, in order to increase the crease recovery effect of the fluid member 5, the main body portion 11 is provided in a trapezoidal structure.

Preferably, the inner vamp 18 and the outer vamp 19 are integrally formed, as shown in fig. 6, the inner vamp 18 and the outer vamp 19 are bonded together by means of adhering or sewing; preferably, in order to prevent the fluid member 5 disposed between the inner upper 18 and the outer upper 19 from falling off when the user runs or exercises vigorously, stitches are applied at the contour of the fluid member 5 between the inner upper 18 and the outer upper 19 using stitches, closing the fluid member 5 between the inner upper 18 and the outer upper 19. Preferably, in order to increase the breathability of the upper, both the inner upper 18 and the outer upper 19 are chosen to be of a highly breathable mesh structure; of course, leather or the like may alternatively be used for exterior upper 19.

The above all discusses a double upper structure with an inner upper 18 and an outer upper 19, which may also be a single upper, with the fluid member 5 being disposed inside the single upper; the use of the fluid member 5 with a vamp having a tongue structure is also discussed above, as is the use of the fluid member 5 with a unitary vamp having no tongue structure.

The specific working method of the vamp material structure of the invention is as follows: the shoe wearer stretches feet into the shoes, when the user runs or walks, during the pedaling action of the feet, the vamps can bend, the feet bend at the metatarsophalangeal joints formed by the proximal phalanges and the metatarsals, the instep drives the vamps to deform in an extruding mode, the instep generates an extruding force on the vamps, fluid in the fluid members 5 is extruded into the bifurcating parts 12 through the main body part 11, the outer sides of the bifurcating parts 12 are made to expand, the expanded outer sides can well stretch and straighten the vamps bent when the vamps are bent, vamp creases at the places can be actively repaired, meanwhile, the fluid members 5 in the main body part 11 can absorb vamp bending force at the places corresponding to the main body part 11, and vamp creases at the places can be relieved. When the foot is in the extended state, i.e. when the foot is not bent, the instep stops producing the pressing force on the upper, the outer edge inside the crotch 12 contracts, and the fluid is pressed into the main body 11 again, and since the fluid member 5 releases the upper all the time, it can absorb the bending force produced when the upper is bent all the time by the fluid. Since the crotch portion 12 and the main body portion 11 are both in a communicating state, it is possible to cope with a complicated vamp bending situation, and if a sudden force is generated at a certain place, the force can be transmitted to another place of the fluid member 5 by the fluid, so that the shock can be absorbed by the entire fluid member 5, rather than being borne by a certain place.

The breathable mesh vamp capable of automatically eliminating the shoe marks is characterized in that the fluid component 5 is arranged in the vamp, the fluid component 5 is always in contact with the vamp and can absorb the bending force when the vamp is bent, meanwhile, the fluid component 5 is of a claw-shaped structure, the structure of the fluid component is suitable for the stress condition when the vamp is bent, and the fluid component 5 can be used for well stretching and smoothing the vamp bent when the vamp is bent through expansion deformation, so that the crease marks of the vamp at the position can be actively repaired, and the shoe marks can be automatically eliminated. Meanwhile, since the crotch part 12 and the main body part 11 are in a communicated state, it can cope with a complicated shoe upper bending situation, and if a sudden force is generated at a certain position, the force can be transmitted to other parts of the fluid member 5 by the fluid, so that the shock can be absorbed by the whole fluid member 5, instead of being borne by the certain position, and the wear resistance and the comfort of the shoe upper material structure are further improved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
