Description

Technical Field

[0001] The invention relates to the technical field of soles and shoes, in particular to a non-slip sole with a fulcrum capable of protecting plantar fascia and a shoe with the sole. Background Art

[0002] Currently, shoe soles include a heel, an arch, and a forefoot. Specifically, the heel corresponds to the human heel, the arch corresponds to the arch of the foot, and the forefoot corresponds to the forefoot. When a person runs, the metatarsophalangeal joint is the primary contact point when the forefoot strikes the ground. Therefore, the metatarsophalangeal joint is subject to significant impact and significant bending. The metatarsophalangeal joint connects the metatarsal heads to the phalanges. The front end of the plantar fascia connects to the metatarsal joint, while the rear end connects to the heel. Therefore, the plantar fascia is stretched during running or walking, and the front end of the plantar fascia is subject to significant impact when the forefoot strikes the ground, making it susceptible to injury and potentially leading to plantar fasciitis or plantar fascia tears. The main causes of plantar fascia tears include: prolonged walking and standing, which can also cause plantar fascia strain and tearing; and strenuous exercise, such as jumping from a height, or running and basketball. Existing soles only focus on protecting the heel and arch of the foot, such as setting an air bag at the heel of the sole and setting an arch support structure at the arch of the sole. The existing soles have insufficient or poor protection effect on the plantar fascia, and it is necessary to improve them. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and firstly provide a sole which has a better protective effect on the plantar fascia.

[0004] The purpose of the present invention is achieved through the following technical solutions.

[0005] The invention discloses a non-slip shoe sole with a fulcrum capable of protecting the plantar fascia, comprising an arch portion and a forefoot portion, wherein an end of the forefoot portion relatively close to the arch portion is provided with a fulcrum protrusion.

[0006] Preferably, the fulcrum protrusion is formed with a protrusion bottom surface, and a first concave suction cup portion is formed on the protrusion bottom surface.

[0007] Preferably, the first concave suction cup portion is circular.

[0008] Preferably, the fulcrum protrusion is tilted with the front lower and the rear higher.

[0009] Preferably, the fulcrum protrusion is arranged in the center in the left-right direction.

[0010] Preferably, the arch portion is formed with an arch recess, and a support block is formed in the arch recess.

[0011] Preferably, the support block and the fulcrum protrusion are connected as one body.

[0012] Preferably, the support block and the fulcrum protrusion are separately arranged.

[0013] Preferably, the support block is formed with a support block bottom surface, and a second concave suction cup portion is formed on the support block bottom surface.

[0014] The present invention also provides a shoe, which includes a fulcrum anti-slip sole that can protect the plantar fascia according to any of the above technical solutions, and a shoe body is provided on the fulcrum anti-slip sole that can protect the plantar fascia, and a shoe wearing cavity is formed in the shoe body.

[0015] Compared with the prior art, the present invention has the following advantages: (1) By providing a fulcrum protrusion at one end of the forefoot portion, which is relatively close to the arch of the foot, the impact force on the metatarsal heads and metatarsophalangeal joints can be reduced, thereby effectively protecting the metatarsal heads, metatarsophalangeal joints, and plantar fascia. The fulcrum protrusion also facilitates easy and flexible turning and walking. (2) Because the shoes of the present invention are provided with the soles of the present invention, the shoes of the present invention effectively protect the plantar fascia.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The anti-skid sole with fulcrum that can protect plantar fascia of the present invention is as follows Figure 1 and Figure 2 As shown, the shoe comprises an arch portion 3 and a forefoot portion 2. When a person wears the shoe, the arch portion 3 corresponds to the arch of the foot, and the forefoot portion 2 corresponds to the forefoot of the human body. A fulcrum protrusion 4 is provided at one end of the forefoot portion 2 closer to the arch portion 3. In other words, the fulcrum protrusion 4 protrudes downward relative to the bottom of the forefoot portion 2. The sole of the present invention can be made of a soft and elastic material such as rubber or foamed polyurethane.

[0030] like Figure 3 As shown, when running, the forefoot usually touches the ground first, so the metatarsophalangeal joint is mainly impacted by the ground 99, including the metatarsal head 981. Since the fulcrum protrusion 4 is located at the end of the forefoot portion 2 relatively close to the arch portion 3, the fulcrum protrusion 4 roughly corresponds to the metatarsal head 981, so the fulcrum protrusion 4 first contacts the ground 99. Specifically, people's running habits are different. If the angle between the sole and the ground is small when landing, the end of the fulcrum protrusion 4 relatively close to the arch portion 3 will touch the ground first. If the angle between the sole and the ground is large when landing, such as Figure 3As shown, the front end of the fulcrum protrusion 4 (i.e., the end of the fulcrum protrusion 4 relatively far away from the arch portion 3) touches the ground first. When a person walks, the heel 1 usually touches the ground first, and then the end of the fulcrum protrusion 4 relatively close to the arch portion 3 touches the ground. Due to the gravity of the human body, the fulcrum protrusion 4 will produce elastic compression deformation when it touches the ground, thereby having a shock-absorbing effect, reducing the impact force on the metatarsal head 981 and the metatarsophalangeal joint, and since the front end of the plantar fascia is connected to the metatarsophalangeal joint, the fulcrum protrusion 4 also plays a better role in protecting the plantar fascia; since the fulcrum protrusion 4 is actually convex downward, the contact area between the fulcrum protrusion 4 and the ground 99 is smaller than that of the entire forefoot portion 2 of the sole contacting the ground 99, so the pressure on the fulcrum protrusion 4 is greater, so the fulcrum protrusion 4 is easier to produce a larger amplitude of elastic deformation, and the effect of absorbing impact energy is better. When the forefoot of a person touches the ground, the fulcrum protrusion 4 contacts the ground 99. At this time, the person turns, the foot 98 rotates, and the foot 98 drives the sole to rotate. Since the contact area between the fulcrum protrusion 4 and the ground 99 is relatively small, the resistance torque of the ground 99 when the sole rotates is small, so the person can turn and walk more easily and flexibly. For example, when playing basketball, it is often encountered that the forefoot of a person touches the ground and turns.

[0031] Furthermore, if Figure 2 As shown, the fulcrum projection 4 is formed with a projection bottom surface 40, as shown in FIG. Figure 1 As shown, a first concave suction cup portion 401 is formed on the bottom surface 40 of the protrusion, that is, the first concave suction cup portion 401 is an upwardly concave portion. When a person walks or runs, the fulcrum protrusion 4 contacts the ground 99, and the fulcrum protrusion 4 is elastically compressed and deformed to discharge the air in the first concave suction cup portion 401. As a result, the first concave suction cup portion 401 can produce an adsorption effect on the ground 99 through the action of negative pressure, as shown in FIG. Figure 5 As shown, when a person walks on a smooth ground 99, the above-mentioned suction effect is better, thus preventing the person from slipping. By providing the first concave suction cup portion 401 on the bottom surface of the protrusion 40, the actual contact area between the bottom surface of the protrusion 40 and the ground 99 is reduced, which is conducive to reducing the resistance of the ground 99 when the sole rotates.

[0032] Furthermore, if Figure 1 As shown, the first concave suction cup portion 401 is circular, so when a person turns while walking, since the circular first concave suction cup portion 401 is isotropic in the horizontal plane, the steering jam can be avoided. Since the edge of the first concave suction cup portion 401 is circular, the edge of the first concave suction cup portion 401 can guide the horizontal steering of the sole. It can also be understood that the slight bumps and depressions on the ground 99 are relatively guided by the edge of the first concave suction cup portion 401 and slide along the arc.

[0033] Furthermore, if Figure 1 and Figure 2As shown, the fulcrum protrusion 4 is tilted so that the front is lower and the rear is higher, that is, the rear end of the fulcrum protrusion 4 protrudes downwardly relative to the forefoot portion 2 to a greater extent, while the front end of the fulcrum protrusion 4 protrudes downwardly relative to the forefoot portion 2 to a smaller extent; when running, when the forefoot of a person touches the ground, the sole approaches the ground 99 in an inclined form with the rear higher and the front lower relative to the ground 99, so that the tilted setting of the above-mentioned fulcrum protrusion 4 adapts to the actual running action, avoids the fulcrum protrusion 4 from blocking the ground 99, and allows people to run normally; and because the heel portion 1 of the sole protrudes downwardly relative to the forefoot portion 2, the tilted setting of the above-mentioned fulcrum protrusion 4 is conducive to a smooth transition from the heel portion 1 to the forefoot portion 2.

[0034] Furthermore, if Figure 1 As shown, the fulcrum protrusion 4 is centered in the left-right direction, which avoids the situation where one side of the sole is significantly higher and the other side is significantly lower in the left-right direction, which is conducive to people walking steadily; and because the fulcrum protrusion 4 is located on the corresponding lower side of the transverse arch of the foot 98, when a person walks or runs, the weight of the person is applied to the sole, and the fulcrum protrusion 4 contacts the ground 99, which will cause the fulcrum protrusion 4 to elastically shift upward relative to the bottom of the sole, so that the fulcrum protrusion 4 can support the transverse arch of the foot 98, avoiding the transverse arch of the foot 98 from frequently collapsing and causing transverse arch collapse lesions, so the sole of the present invention has a good protective effect on the transverse arch.

[0035] Furthermore, if Figure 1 As shown, the arch portion 3 is formed with an arch recess 30, and a support block 31 is formed in the arch recess 30, so that the support block 31 is located on the rear side of the fulcrum protrusion 4, such as the Chinese invention patent application publication number CN118806016A "A friction-assisted sole capable of protecting the arch of the foot and a shoe having the same", when a person walks, the support block 31 is provided, which increases the structural strength of the corresponding arch portion of the sole, thereby avoiding the sinking phenomenon of the corresponding arch portion of the sole during walking, so that the sole of the present invention has a better supporting effect on the arch of the foot; during walking, the heel of the person leaves the ground first when starting, so that the heel portion 1 of the sole leaves the ground first, and the sole is warped as a whole, but at this time the support block 31 can still contact the ground 99, so the support block 31 increases the friction between the sole and the ground 99, thereby obtaining a starting-assisting effect. Since the support block 31 is located on the rear side of the fulcrum protrusion 4, during walking, when starting, the person's heel leaves the ground first, and then the support block 31 leaves the ground. At this time, the fulcrum protrusion 4 can still contact the ground 99. Therefore, the fulcrum protrusion 4 can serve as a continuation of the functional structure for increasing the friction between the sole and the ground 99, making the starting resistance effect of the sole better.

[0036] Furthermore, if Figure 1As shown, the support block 31 is connected to the fulcrum protrusion 4 as a whole, which is beneficial to increasing the connection strength between the support block 31 and the fulcrum protrusion 4, and is beneficial to increasing the structural rigidity of the middle position of the sole in the front-back direction, thereby helping to increase the stability of the sole.

[0037] In some embodiments, as Figure 4 As shown, the support block 31 and the fulcrum protrusion 4 are separately provided, so that a gap 5 is formed between the support block 31 and the fulcrum protrusion 4. When a person runs, the sole will bend significantly, and the formation of the gap 5 is conducive to the flexible bending of the sole.

[0038] Furthermore, if Figure 2 As shown, the support block 31 is formed with a support block bottom surface 310, as shown in FIG. Figure 1 As shown, a second concave suction cup portion 3101 is formed on the bottom surface 310 of the support block. When a person walks or runs, the support block 31 contacts the ground 99, and the support block 31 is elastically flattened and deformed to discharge the air in the second concave suction cup portion 3101. The second concave suction cup portion 3101 can then produce an adsorption effect on the ground 99 through the action of negative pressure. When walking, during the process of the foot landing, the second concave suction cup portion 3101 first connects to the ground 99, and then changes to the first concave suction cup portion 401 to connect to the ground 99. Therefore, when starting, the rear part of the second concave suction cup portion 3101 separates from the ground 99, but the first concave suction cup portion 401 is still connected to the ground 99. In other words, although the sole will bend and deform when a person walks, the coordinated work of the second concave suction cup portion 3101 and the first concave suction cup portion 401 increases the time the sole adheres to the ground 99, thereby preventing people from slipping when walking on smooth surfaces. For example, when a person walks on a smooth ice surface, the second concave suction cup portion 3101 and the first concave suction cup portion 401 can adhere to the ice surface, thereby reducing the risk of slipping. When a person walks on a rugged road, the raised parts on the road can be relatively inserted into the second concave suction cup portion 3101 and / or the first concave suction cup portion 401, and the raised parts on the road can better support the force exerted by the person walking, thereby preventing slipping; Figure 6 As shown, especially when walking on the mountain road 97, the raised portion 971 on the road can be inserted into the second concave suction cup portion 3101 and / or the first concave suction cup portion 401, that is, the second concave suction cup portion 3101 and / or the first concave suction cup portion 401 is hooked with the raised portion 971 on the road. Therefore, during the process of going up and down the mountain, the raised portion 971 on the road can better support the weight of the human body, increase the hindering effect of the mountain road 97 on the sole, avoid slipping, and help improve walking safety. The sole of the present invention is particularly suitable for mountaineering shoes.

[0039] like Figure 1As shown, the bottom of the sole of the present invention is also formed with anti-skid grooves 201 and anti-skid transverse grooves 202. The anti-skid grooves 201 are distributed within the range of the heel 1 and the forefoot 2, and the anti-skid transverse grooves 202 run through the bottom of the sole from left to right. The anti-skid transverse grooves 202 are spaced apart in the front and back directions. Therefore, the sole of the present invention has a first anti-skid structure: anti-skid grooves 201; a second anti-skid structure: anti-skid transverse grooves 202; a third anti-skid structure: a second concave suction cup portion 3101 and a first concave suction cup portion 401; and a fourth anti-skid structure: the front end edge of the fulcrum protrusion 4 and the rear end edge of the support block 31; therefore, the sole of the present invention has a four-fold anti-skid effect, and the anti-skid performance is outstanding.

[0040] like Figure 7 As shown, in some embodiments, a square island block 89 is formed in the first concave suction cup portion 401 and / or the second concave suction cup portion 3101, and the square island block 89 is sunken, that is, Figure 8 As shown, the depth dimensions of the first concave suction cup portion 401 and the second concave suction cup portion 3101 are respectively greater than the height dimensions of the corresponding square island block 89. The edge of the square island block 89 can grip the raised portion of the ground 99 to provide an anti-slip effect. Since the square island block 89 is set downward, when the support block 31 is elastically flattened and deformed to expel the air in the second concave suction cup portion 3101, or when the fulcrum protrusion 4 is elastically flattened and deformed to expel the air in the first concave suction cup portion 401, the square island block 89 can still not contact the ground 99, thereby having little effect on the negative pressure adsorption effect of the first concave suction cup portion 401 and the second concave suction cup portion 3101. The adsorption effect of the first concave suction cup portion 401 is combined with the gripping of the square island block 89 on the raised ground within the range of the first concave suction cup portion 401 to form a composite anti-slip effect, thereby providing better anti-slip performance.

[0041] like Figure 9 As shown, in some embodiments, the first concave suction cup portion 401 and / or the second concave suction cup portion 3101 are formed with a front arrow-shaped protruding tooth 881 and a rear arrow-shaped protruding tooth 882. That is, the arrow-shaped protruding tooth 881 is in the shape of an arrow pointing forward, and the rear arrow-shaped protruding tooth 882 is in the shape of an arrow pointing backward. Thus, the front arrow-shaped protruding tooth 881 and the rear arrow-shaped protruding tooth 882 can grip a raised portion of the ground. The front arrow-shaped protruding tooth 881 and the rear arrow-shaped protruding tooth 882 are sunken.

[0042] like Figure 10 As shown, in some embodiments, the first concave suction cup portion 401 and / or the second concave suction cup portion 3101 are formed with a front arched arc-shaped protruding tooth 871 and a rear arched arc-shaped protruding tooth 872. That is, the front arched arc-shaped protruding tooth 871 is in the shape of an arc that arches forward (which can be a continuous arc or a discontinuous arc), and the rear arched arc-shaped protruding tooth 872 is in the shape of an arc that arches backward. Therefore, the front arched arc-shaped protruding tooth 871 and the rear arched arc-shaped protruding tooth 872 can grip the raised part of the ground. The front arched arc-shaped protruding tooth 871 and the rear arched arc-shaped protruding tooth 872 are set downward.

[0043] like Figure 9 As shown, when a person walks up the mountain, the front arrow-shaped convex tooth 881 can clamp the convex part 971 on the road. Similarly, when a person walks down the mountain, the rear arrow-shaped convex tooth 882 can clamp the convex part 971 on the road. When a person walks up the mountain, the front arch-shaped convex tooth 871 can clamp the convex part 971 on the road. When a person walks down the mountain, the rear arch-shaped convex tooth 872 can clamp the convex part 971 on the road.

[0044] like Figure 11 As shown, it is well known that when people are skateboarding, one foot may support the ground while the other foot is on the skateboard. At this time, the anti-slip grooves 201 of the forefoot portion 2 of the sole of the present invention can form strong mutual friction with the skateboard, and the first concave suction cup portion 401 and / or the second concave suction cup portion 3101 can hold the skateboard (when the top of the skateboard is relatively smooth), or the first concave suction cup portion 401 and / or the second concave suction cup portion 3101 can clamp the rough particles on the surface of the skateboard, thereby preventing the foot stepping on the skateboard from slipping, which is conducive to the normal progress of skateboarding. Therefore, the sole of the present invention is also suitable for use in the field of skateboarding.

[0045] The shoes of the present invention include the above-mentioned anti-skid sole with fulcrum that can protect the plantar fascia, such as Figure 3 As shown, the anti-slip sole with a fulcrum that can protect the plantar fascia is provided with a shoe body 6, and a shoe wearing cavity is formed in the shoe body 6. The foot 98 can be inserted into the shoe body 6. For example, the lower end of the shoe body 6 is bonded to the upper edge of the sole of the present invention. Since the shoe of the present invention is provided with the sole of the present invention, the shoe of the present invention has a better protection effect on the plantar fascia and metatarsophalangeal joint.
