Description

Shoe capable of changing along with foot arch

Technical Field

The utility model relates to a shoes technical field, in particular to shoes that can change along with arch of foot.

Background

The human foot is mainly composed of three parts: the sole comprises a half sole, an arch and a heel, wherein the arch plays a role in damping and supporting the human body through special deformation characteristics of the arch. Therefore, the size of the human foot will vary at different times due to the deformation of the arch, and the foot length in the morning will be less than the foot length in the afternoon. The size of the shoe can not be changed along with the change of the foot length, so that when people do sports, particularly when people do strenuous sports like basketball playing, the shoe cannot completely fit and cover the foot due to the size of the shoe, shearing force can be generated between the shoe and the surface of the sole of the foot, the shearing force is the main reason for generating blisters and calluses in the metatarsal bone area of the sole of the foot, and ankle sprain or fracture can be generated in severe cases. Therefore, a pair of shoes which can be deformed together with the arch of foot is very important, which not only can greatly reduce the occurrence of sports injury, but also can increase the wrapping property of the foot, so that people feel more comfortable.

Re-fit extendable science and technology of plum

The stretching technology of plum is that the midsole of a shoe is incompletely cut, and a large deformation is generated by using the elasticity of the material and the space after cutting, so that the shoe shows an extended characteristic after being loaded to adapt to the change of the human arch.

Disadvantages of the prior art

The existing structure has the following defects: (1) through the sole after the cutting, though produced better ductility, lead to the weak of sole connection position material, compared with the sole after the cutting that has the sole risk of easily breaking (2), in order to adapt to the change of foot, need more time to accomplish the deformation process, also can produce more time to recover equally, this just can lead to the shoes can not be timely with elastic potential energy transmission to the foot to the load of foot and the risk of sports injury have been increased.

Disclosure of Invention

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the utility model is composed of a sole and a vamp, wherein the sole is composed of an EVA foaming insole 1, a TPU supporting plate 2 and a rubber outsole with a structure 7, the shape of the EVA insole is shown in figure 1, and the hollowed part of the sole is a deformation space provided for the shoe under the stress condition; the rubber outsole 7 is attached to the contact surface of the EVA midsole 1 through shoe rubber, so that the wear resistance and the slip resistance of the sole are improved; the TPU supporting plate 2 is adhered to the middle part of the EVA insole 1 through shoe glue, so that the stability of the shoe and the foot coating feeling are improved; the upper 3 is made of a knitted material having a certain elasticity. The upper surface 3 is provided with a pig nose button 4, a shoelace 5 with good elasticity and a plastic gasket 6 which jointly form a rapid and convenient lacing system. The plastic pad 6 is adhered on the upper surface 3 through shoe glue, and the shoelace 5 passes through the round hole of the pig nose buckle 4 and the hole on the upper surface 3 and is sewn on the plastic pad 6. The upper surface 3 and the EVA insole 1 are bonded together through shoe glue.

As shown in fig. 2, which is a cross-sectional view of a sole, the sole is composed of an EVA midsole 1, a TPU support plate 2, a carbon fiber plate 8, a silica gel pad 9, and a midsole cloth 10 having good elasticity. The carbon fiber plate 8 is formed in a curved-like configuration on its side, with its ends positioned in the metatarsal and calcaneus areas of the corresponding foot, as shown in fig. 4, and embedded in the EVA midsole 1. A silica gel pad 9 is attached to the upper part of the carbon fiber plate 8 and is bonded to a middle base fabric 10.

As shown in fig. 3, shoelace 5 passes through the circular hole of nose buckle 4, presses structure 11 downwards, can compress spring 13 and contract for structure 11 corresponds with the round hole of base 12, and pull shoelace 5 adjusts to suitable position, loosens structure 11, and the resilience effect of spring 13 can make structure 11 stagger each other with the round hole of base 12, blocks the shoelace, realizes the purpose of frenulum.

The utility model discloses utilize the combined structure design that the pliability and the easy deformation's of the high elasticity of carbon fiber plate and high tenacity and silica gel pad characteristic and EVA material insole go on, not only strengthened the shock attenuation effect and the buffer capacity of shoes, realized the characteristic that shoes changed along with the arch of foot change more. Meanwhile, the simple shoelace is more convenient to design, and the body sensing effect of the foot is also improved.

As shown in fig. 4, after the foot is stressed, the arch of foot will produce longitudinal tensile deformation, the stress point of the foot is mainly at the bottom of metatarsal and calcaneus of the foot, the carbon fiber plate 8 located below the foot will deform under stress to produce extension in the front-back direction, the EVA midsole 1 at the outer side will also produce extension in the front-back direction under the pushing of the carbon fiber plate 8 and the stress of the foot, the soft characteristic of the silica gel pad 9 will reduce the impact force of the ground to the foot, and the rigidity of the TPU support plate increases the support for the stability of the arch of foot. The foot leaves ground afterwards, under the characteristic of the 8 high resilience of carbon fiber sheet, can resume the initial condition at once to drive EVA insole 1's deformation and resume, thereby reach the purpose that suits the foot, with elastic potential energy repayment in the foot simultaneously, let the people more laborsaving.

The carbon fiber plate 8 of "bow-shaped" structure can produce better ductility after the atress, and rather than the EVA foaming insole 1 that meets then can produce the elastic deformation of bigger degree under the promotion of carbon fiber plate, and the hollow out construction of its bottom also provides great spatial dimension for the compression deformation of insole, has guaranteed the extensibility of sole. The carbon fiber plate 8 with the arch structure can generate higher rebound effect due to the unique structure and provide larger energy feedback for the foot by combining with the EVA foaming midsole 1. The soft silica gel pad 9 and EVA foaming insole 1 and carbon fiber plate 8 store energy through respective deformation characteristic to reduce ground reaction force, realize better cushioning effect.

The good extensibility of shoes can realize the effect of mutual flexible between shoes and the arch of foot to reduce the mutual friction of shoes and foot, reduced the risk of sole skin damage, the bigger elastic deformation of sole also can absorb more impact forces and bring more energy for the foot and return simultaneously, reduces people's energy consumption, improves people's motion performance.
