The human foot skeleton is constructed as shown in figure 1 and comprises five toes, each consisting of a plurality of phalanges and a metatarsus, such as the big toe consisting of a distal phalange 51, a proximal phalange 52 and a first metatarsus 53, and similarly, the index, middle, innominate and little toes consisting of a plurality of phalanges and

second metatarsals

54, 55, fourth metatarsus 56 and fifth metatarsus 57, and first, second and

third cuneiforms

58, 59 and 60, respectively, with navicular 61 and cuboid 62, and then ankle 10 and calcaneus 20. When people walk or run, buckle repeatedly between near-end phalanx and the metatarsus to make the vamp take place to buckle repeatedly, form the crease, what is more, take place to come unstuck the phenomenon in the veneer department of vamp and sole, seriously influence the life of shoes, simultaneously, the vamp of buckling also can extrude inside foot, influences the travelling comfort of people's dress shoes. To address the problem of vamp creases and the problem of shoe vamp and sole degumming, some improved vamp structures also appear in the prior art: for example, patent document 1 discloses a durable shoe, in which a vamp is divided into a front upper and a rear upper, a mesh elastic cloth vamp is used as a connecting surface between the front upper and the rear upper, the front upper and the rear upper are made of soft cowhide, the connecting surface is arranged at a bent part at the front part of the vamp, the front vamp is not easy to generate creases by using the soft and high-elasticity characteristics of the mesh elastic cloth, but the vamp structure is not integrally formed, different materials are required to be cut and combined together, the processing is complicated, the mesh elastic cloth can also have creases after being used for a long time, and the crease problem is not fundamentally improved; as another example, patent document 2 discloses a shoe in which an upper is divided into a first upper member and a second upper member which are relatively movable, and when a foot performs a pedaling action and bending movement of the upper, a front end edge portion of the second upper member slides longitudinally on the first upper member, and a rear end edge portion of the first upper member slides longitudinally under the second upper member, which improves the problem of creasing of the upper, but since the first upper member and the second upper member can slide relatively, when the foot is bent, only a bending resistance force is provided by a sole, although the bending resistance force of the upper is changed, bending wear of the sole is increased invisibly, and meanwhile, since only the sole provides the bending resistance force, the foot is easily injured during running or other violent exercises, and further, the upper is deformed by a passive force and cannot be actively recovered; as another example, patent document 3 discloses a wear-resistant shoe, in which an elastic pad 16 is adhered to the outer surface of an upper, a series of grooves 38 are formed in the elastic pad, the grooves are arranged in a radial manner, and the deformation of the grooves 38 is used to absorb the bending deformation of the upper, although the service life of the upper can be prolonged, the elastic pad 16 absorbing the bending deformation only passively absorbs the deformation force, and the radial center 30 determined by the grooves 38 is a certain point, so that the shoe can only be applied to a foot with a specific size and length, and the universality is poor; also, as shown in patent document 4, a flat shoe is disclosed, in which a triangular structure is cut out from a bent portion of a sole, and then a soft material is sewn to the triangular structure, so as to improve the stress condition of the sole and prolong the service life of the mesh shoe, but a crease portion is also present.

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. Also, during the pedaling action of the foot, the bending of the upper generates a counter bending force F1 that tends to disengage the upper from the foot and interfere with the person's progress or running.

As shown in fig. 3 to 5, the adaptive upper for fitting a foot according to the present invention includes an inner upper 18, an outer upper 19, a fluid member 5 and a fastening member 21 which are disposed between the inner upper 18 and the outer upper 19, the inner upper 18 and the outer upper 19 together forming an upper 3, a lower portion of the upper 3 being fixedly attached with a sole 2, the upper 3 covering a foot 1 of a wearer, an upper portion of the upper 3 being provided with a tongue 6, the fastening member 21 being disposed at a rear portion of the upper 3, an edge of a receiving space formed by the upper 3 for receiving the tongue 6 forming an upper boundary 16 of the upper, the fluid member 5 including a main body portion 11 and at least two bifurcations 12, the overall being of a claw-shaped structure, the main body portion 11 being located at an upper end portion of the upper 3, and an upper edge of the main body portion 11 being parallel to the upper boundary 16 of the upper, a lower end of the main body portion 11 being, each bifurcation 12 is a strip-shaped structure having a bifurcation body axis 9, the bifurcation body axes 9 meeting at a point O, which falls between the upper edge of the body portion 11 and the upper vamp border 16, preferably at the upper edge of the body portion 11. The fastening member 21 communicates with the crotch 12 through a communication conduit 22, and both the fastening member 21 and the communication conduit 22 are disposed between the inner vamp 18 and the outer vamp 19. 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, the fastening member 21 includes a rear side 23, a front flange 24 and a fluid 15 disposed inside the rear side 23 and the front flange 24, wherein the rear side 23 and the front flange 24 are made of a sealing film material, such as a polyurethane film, and the calcaneus is clamped only by the shape deformation of the fastening member 21. It is further preferred that the material used for the rear side 23 and the front flange 24 have different stretch properties, that the rear side does not expand or contract with more or less fluid, and that the front flange 24 expands or contracts with more or less fluid, for example, the rear side 23 is made of polyurethane, the front flange 24 is made of rubber type or the like, and that the rear side 23 and the front flange 24 can be sealed by heat sealing or RF sealing. Preferably, the front flange 24 may be of an annular configuration to provide good traction around the calcaneus bone and to prevent the shoe from falling off the foot while improving comfort. When the shoe upper is bent, the instep presses the fluid in the main body 11 so that the fluid flows toward the crotch 12, the fluid flows toward the fastening member 21 through the communication channel 22, and the front flange 24 of the fastening member 21 is expanded to some extent due to the increase of the fluid, so that the fastening member 21 protrudes and locks the calcaneus 20, thereby preventing the shoe upper from being separated from the foot during the pedaling action. Through the arrangement of the fluid member 5 and the fastener 21, the folded crease of the vamp can be actively recovered during pedaling action, the force for locking the heel is increased, and the shoes are prevented from being separated from the feet when the shoelace is loosened. When the foot is in the extended state, i.e. not bending, the instep stops exerting a compressive force on the upper, and the front flange 24 contracts, pressing the fluid 15 into the fluid member 5.

As shown in fig. 6, 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. 7, 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 wearer inserts his foot into the shoe and, during the pedaling action of the foot as the user runs or walks, the upper bends, the foot bends at the metatarsophalangeal joint formed by the proximal phalanges and the metatarsals, the instep drives the vamp to deform by extrusion, the instep generates an extrusion force on the vamp, fluid in the fluid component 5 is extruded into the bifurcation part 12 from the main body part 11, the fluid further enters the fastening piece 21 through the communication pipeline 22, the fluid enables the outer side of the bifurcation part 12 to expand, the expanded outer side can well stretch and straighten the vamp which is bent when the vamp is bent, therefore, the fold of the vamp at the position is actively repaired, at the same time, the fluid expands the front flange in the fastening piece 21 to fasten the calcaneus 20, the fluid member 5 in the main body part 11 can absorb the vamp bending force at the corresponding position of the main body part 11, and the situation of the vamp fold at the position can be relieved. When the foot is in the extended state, that is, when the foot is not bent, the instep stops generating the pressing force to the upper, the front flange in the fastening member 21 contracts, the outer edge in the crotch 12 contracts, and the fluid is pressed into the main body 11 again, and the fluid member 5 releases the upper at all times, so that the bending force generated when the upper is bent can be absorbed by the fluid at all times. 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.

According to the self-adaptive vamp fitting the foot, the fluid member 5 and the fastening piece 21 are arranged in the vamp, the fluid member 5 is always in contact with the vamp and can absorb the bending force when the vamp is bent, meanwhile, the fluid member 5 is of the claw-shaped structure, the structure adapts to the stress condition when the vamp is bent, the fluid member 5 can be used for well unfolding and smoothing the vamp bent when the vamp is bent through expansion deformation, so that the crease of the vamp at the position is actively repaired, meanwhile, the fastening piece 21 also adapts to the bending action of the vamp, and the heel bone 20 is fastened when the vamp is bent, so that the shoe is prevented from being separated from the heel. 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 positions of the fluid member 5 through the fluid, so that the vibration 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 integrated shoe upper 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.
