Description

Technical Field

[0001] The utility model relates to the technical field of insoles and shoes, in particular to a sole. Background Art

[0002] In the current aviation education system, high school students face increasingly demanding training tasks, requiring frequent physical training and ground simulations. However, existing training shoes fail to adequately address the specific needs of high school students, resulting in poor training outcomes and potentially even adversely affecting their foot health.

[0003] Patent number CN201610316907.8 discloses a sports shoe and a sole with center-of-gravity guidance and stabilization function. The sole comprises an upper and lower sole bonded together. The bottom surface of the lower sole is provided with a center-of-gravity guidance groove extending from the forefoot to the heel. The center-of-gravity guidance groove is provided with a plurality of holes. The upper sole extends downwardly from a plurality of support columns, which are fixedly engaged with the holes in a one-to-one correspondence. This invention provides a center-of-gravity guidance groove on the lower sole. The support columns extending from the lower sole are embedded in the holes in the center-of-gravity guidance groove. During foot movement, the sole is guided to deform along a trajectory that is closest to the physiological changes of the foot under stress, thereby improving foot stability and comfort, preventing sports injuries, and improving exercise efficiency.

[0004] Since the support column extending from the bottom of the invention is embedded in the hole in the center of gravity guide groove, the support column in the hole offsets the force applied to the groove by both sides of the groove, and the force of the sole is dispersed, making the sole unstable during strenuous activities. At the same time, the patented sole adopts the method of covering the entire sole with the same pattern around the center of gravity guide groove, and does not distinguish between functional areas of the pattern.

[0005] The invention patent, application number 202110848996.1 and publication number CN 113712338 B, discloses a gait guidance device for shoes. The device comprises a support beam adapted to be embedded in the sole along its length and a transverse guide rod intersecting the support beam. The support beam can extend from the forefoot to the heel of the shoe. The guide rod is adapted to be embedded in the sole, with at least a portion of the guide rod's center being offset from the outside of the support beam. The invention is applied to the sole. The guide rod design requires the sole to be hardened, preventing the forces on both sides of the guide rod from being concentrated on the guide rod. This disperses the forces on the sole, making the sole unstable during strenuous activity. According to the dictionary definition of "rod," a hard material can cause discomfort to the foot. Wearing shoes with such a sole for extended periods can cause discomfort, which is unsuitable for the high-intensity training routines of high school students at aviation schools. Furthermore, the patent's sole pattern design utilizes a block-shaped pattern on the sole, without distinguishing functional areas. Utility Model Content

[0006] The present application provides a solution to the problem that high school students in aviation schools are prone to fatigue due to unconcentrated force on their feet during training and that the soles lack functional areas.

[0007] The specific plan is as follows:

[0008] A sole comprises a sole body, wherein the sole body comprises a heel, a rear sole, an arch, a fore sole and a toe in sequence from the heel to the toe, a gravity guide line is provided at the front of the heel, the gravity guide line passes through the rear sole, the arch, the fore sole and enters the rear part of the toe and connects with the toe, the toe and the heel are wear-resistant areas, the outer side of the fore sole and the inner side of the rear sole are braking areas, the inner side of the fore sole and the outer side of the rear sole are stabilization areas, and the arch of the foot is a TPU stabilization sheet.

[0009] Furthermore, the gravity guide line is a gradually narrowing groove from the front of the heel to the rear of the toe.

[0010] Furthermore, the gravity guide line is located in the forefoot part and has an S-shaped structure, and the middle and end parts of the gravity guide line are located in the forefoot part and extend out to both sides of the branch grooves.

[0011] Furthermore, the depth of the gravity guide line grooves at the heel and rear sole parts is shallower than that at other parts, and steps are formed at the depth change points.

[0012] Furthermore, the grooves where the gravity guide lines are located at the heel and the rear sole are sword-shaped structures when viewed from above, the side walls of the grooves are stepped patterns, and the bottoms of the grooves are arc-shaped.

[0013] Furthermore, the wear-resistant areas of the toe and heel are patterns formed by transverse convex ribs, and drainage grooves are provided at the portion where the gravity guide line extends toward the top of the toe.

[0014] Furthermore, a pattern area consisting of multiple triangles is provided in the braking area.

[0015] Furthermore, a plurality of interconnected 'M'-shaped grooves are provided in the stabilizing area.

[0016] Furthermore, the transverse convex ribs in the toe wear-resistant area are thinner than the transverse convex ribs in the heel wear-resistant area.

[0017] Furthermore, the braking area is made of EVA material, and the hardness of the EVA material is 40 Shore C.

[0018] Furthermore, the wear-resistant area is made of high-wear-resistant rubber, and the hardness of the high-wear-resistant rubber is 65 Shore C.

[0019] Compared with the existing technology, the beneficial effects are:

The groove of the gravity guide line located at the heel and rear sole is a sword-shaped structure when viewed from above. The sidewalls of the groove are stepped patterns and the bottom of the groove is arc-shaped. The gravity guide line is a guide line groove that guides the pressure center point of the sole of the foot to run along the trajectory of the main trunk groove and the branch groove, so that the force on the sole is concentrated on the position of the gravity guide line, which can improve the comfort of running. The main trunk groove and the branch groove can effectively guide the running posture, which is particularly effective in stable support running shoes.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the present invention.

[0025] A sole, such as Figure 1 As shown, the shoe comprises a sole body 1, wherein the sole body 1 includes a heel 6, a rear sole 5, an arch 3, a fore sole 4, and the toe 2 in sequence from the heel to the toe 2. A gravity guide line 11 is provided at the front of the heel 6. The gravity guide line passes through the rear sole, the arch, the fore sole, and enters the rear of the toe 2 to connect with the toe 2. The gravity guide line 11 is a guide line groove that guides the pressure center point of the sole to run along the trajectory of the main groove and the branch groove. The gravity guide line 11 concentrates the force of the sole toward the position of the gravity guide line, thereby improving running comfort. The main groove and the branch groove can effectively guide the running posture, which is particularly effective in stable support running shoes.

[0026] The toe 2 and the heel 6 are the wear-resistant area 12, the outer side of the forefoot 4 and the inner side of the rear sole 5 are the braking area 13, the inner side of the forefoot 4 and the outer side of the rear sole 5 are the stability area 14, and the arch 3 is the TPU stability sheet 15. The TPU stability sheet 15 increases the rigidity of the midfoot that is prone to twisting during exercise and enhances the stability and safety of the foot. At the same time, the TPU stability sheet 15 is existing technology and will not be elaborated on again.

[0027] The gravity guide line 11 is a gradually narrowing groove from the front of the heel to the rear of the toe 2.

[0028] The gravity guide line 11 is located in the forefoot 4 and has an S-shaped structure. The gravity guide line 11 is located in the middle and end parts of the forefoot 4 and extends to both sides with branch grooves 112. Because the human foot is wider than the heel and arch, and the contact area between the foot and the sole is larger, the S-shaped structure and the branch grooves are designed to guide the force on the bottom of the human foot to concentrate in the direction of the gravity guide line.

[0029] The depth of the gravity guide line 11 located at the heel 6 and the rear sole 5 is shallower than that at other parts, and the depth change forms a step.

[0030] The gravity guide line 11 is located in the groove at the heel 6 and the rear sole 5, which has a sword-shaped structure when viewed from above. The side walls of the groove are stepped patterns, and the bottom of the groove is arc-shaped. The stepped pattern adopts a deep groove pattern design to reduce the weight of the sole, so that the sole can be deformed to a large extent when the human body moves, thereby increasing the shock absorption effect.

[0031] The toe 2 and the heel wear-resistant area 12 are patterns composed of transverse ribs, and a drainage groove 16 is provided at the position where the gravity guide line 11 extends to the top of the toe 2. The design of the drainage groove increases the drainage capacity of the sole when it is wet, and at the same time guides the water on the sole to be discharged in a centralized manner, reducing the spread of water splashes on the sole.

[0032] The braking area 13 is provided with a pattern area composed of multiple triangles. The braking area designed with the triangle as the basic pattern can provide excellent grip for the human body when the human body moves in multiple directions.

[0033] The stabilizing area 14 is provided with a plurality of interconnected 'M'-shaped grooves. The design of the 'M'-shaped grooves can increase the contact with the sole and the ground, making daily training more stable and smooth.

[0034] Because the heels and toes of the trainers are easily worn during training, wear-resistant areas are set at the heels and toes. At the same time, because the heels are more easily worn than the toes, the transverse ribs 12 in the toe wear-resistant area 2 are thinner than the transverse ribs 12 in the heel wear-resistant area to adapt to the different degrees of wear between the toes and the heels.

[0035] The braking area 13 is made of EVA material, and the hardness of the EVA material is 40 Shore C. EVA is a prior art. The stabilizing area 14 has the advantages of buffering and shock absorption, high elasticity, improved comfort, and good flexibility.

[0036] The wear-resistant area 12 is made of high-wear-resistant rubber with a hardness of 65 Shore C. High-wear-resistant rubber is an existing technology and can increase the service life of the shoes. At the same time, the drainage groove can improve the drainage efficiency of the sole.

[0037] This technical solution adopts a pattern design of different functional areas running through the sole. The pattern design of different functional areas running through the sole can increase the gripping ability of the sole, thereby increasing the stability of the human body during exercise.

[0038] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
