Description

Technical Field

[0001] The utility model relates to a pair of comfortable shoes with both buffering and power assistance. Background Art

[0002] Strictly speaking, almost all shoes have a buffering function. During walking or running, when the foot moves from motion to stillness relative to the ground, the foot will form a force greater than the weight of the body weight on the ground, and the ground will produce an equal and opposite force on the foot. Buffering is to extend the time from motion to stillness of the foot through the elastic deformation of the sole, thereby reducing the additional impact force, so that the foot, knee joint, and ankle joint are subjected to a relatively small force. After the sole is elastically deformed, part of the kinetic energy is converted into potential energy. When the foot is lifted, the sole exerts a reaction force on the sole, and the rebound forms a boost. The greater the rebound force, the better the boost effect. The purpose of buffering is to reduce the reaction force on the foot. Therefore, soft shoes are conducive to buffering, while rebound requires a material of a certain hardness for support. Generally, shoes with good buffering are suitable for jogging, but are not conducive to increasing speed. Publication No. CN117598559A discloses a sole with anti-skid, wear-resistant and buffering functions. The buffering function is achieved by setting a buffer part. Generally speaking, it is difficult for the same part of the sole to have both excellent buffering and boosting performance. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the utility model is to provide a comfortable shoe with certain cushioning and power-assisting functions.

[0004] To this end, the utility model provides a comfortable shoe that combines cushioning and power assistance, including a sole with a forefoot cushioning portion inside the sole. The forefoot of the sole also includes a rebound portion, and the height of the rebound portion is lower than the height of the forefoot cushioning portion. In this way, when the shoe is in contact with the ground, the sole of the foot is first cushioned by the forefoot cushioning portion and then contacts the rebound portion.

[0005] Furthermore, the forefoot cushioning portion includes a forefoot airbag, the forefoot airbag and the rebound portion are arranged in the knuckle region, and the rebound portion is arranged on the front side of the forefoot airbag.

[0006] The forefoot cushioning portion includes a forefoot airbag, which covers the forefoot, and the forefoot airbag is provided with a plurality of through holes penetrating the airbag corresponding to the knuckle area, and the rebound portion is arranged in the through holes.

[0007] The forefoot cushioning portion includes a forefoot airbag, a U-shaped rebound portion is provided on the outer side of the forefoot airbag, a baffle is provided above the forefoot airbag, and both sides of the baffle cooperate with the rebound portion so that when the forefoot airbag is deformed downward and the height is lower than the upper surface of the rebound portion, the rebound portion supports the baffle.

[0008] Furthermore, the rebound portion includes a V-shaped elastic plate arranged transversely, and the lower side of the elastic plate is fixed on the sole.

[0009] The rebound portion includes an elastic support column.

[0010] Furthermore, it also includes a heel buffer part, which includes a heel airbag. The heel airbag is connected to the forefoot airbag through an air tube. When the heel of the sole is subjected to force, the gas in the heel airbag flows to the forefoot airbag through the air tube. When the heel is lifted and the forefoot is subjected to force, the gas in the forefoot airbag flows to the heel airbag through the air tube, and the rebound part supports the sole of the foot.

[0011] Furthermore, it also includes a midsole, which is arranged above the forefoot airbag, the heel airbag and the rebound part.

[0012] Furthermore, the sole is provided with a forefoot mounting groove and a heel mounting groove, the forefoot mounting groove is fixed with a forefoot airbag and a rebound part, the heel mounting groove is fixed with a heel airbag, the heel buffer part also includes an elastic rib connected to the mounting groove, and the rebound part includes an elastic support column.

[0013] The beneficial technical effects of the utility model are:

[0014] (1) The utility model provides a rebound part and a forefoot buffer part on the forefoot. The deformation amount of the forefoot buffer part under the same stress is greater than the deformation amount of the rebound part. The elastic modulus of the rebound part is greater than that of the forefoot buffer part. The height of the buffer part is greater than that of the rebound part. When the forefoot touches the ground (the center of gravity is transferred from the heel to the forefoot), the forefoot buffer part prolongs the impact time of the foot touching the ground by deformation, thereby reducing its impact force. When the center of gravity of the foot is transferred to the forefoot, the forefoot buffer part is fully elastically deformed, and the forefoot of the sole acts on the rebound part. The rebound part is elastically deformed and quickly applies a large reverse force to the sole of the foot when the forefoot is lifted, thereby improving the forefoot buffering effect while maintaining a good rebound assistance effect.

[0015] (2) In the specific embodiment of the utility model, by providing a heel airbag and a forefoot airbag, the forefoot airbag and the heel airbag are connected by a thin air tube. When the heel touches the ground, the heel airbag is compressed, and the pressure increases so that the gas flows to the forefoot. Then the forefoot touches the ground (at this time, the heel airbag is still compressed). At this time, the forefoot airbag is filled, and the forefoot airbag plays a major role, and the impact force of the forefoot can be well buffered. Then the heel is lifted up, and the forefoot airbag is compressed at this time. The gas is transferred from the forefoot airbag to the rear palm airbag. The rebound part of the forefoot plays a major supporting role, and the rebound part undergoes a large deformation. When the rear foot is lifted up, the rebound part plays a major role and provides rebound assistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] Reference Figures 1 to 5 As shown, a comfortable shoe with both buffering and power assistance of the utility model comprises a sole 1 and an upper, wherein a forefoot buffering part is arranged in the sole 1, and the forefoot of the sole 1 also comprises a rebound part 3, wherein the height of the rebound part 3 is lower than the height of the forefoot buffering part, so that in the process of the shoe contacting the ground, the sole of the foot first buffers with the forefoot buffering part and then contacts with the rebound part 3. The forefoot buffering part and the rebound part 3 can be made of elastic materials, wherein the elastic modulus of the rebound part 3 is greater than that of the forefoot buffering part, that is, the ability of the rebound part 3 to resist elastic deformation is stronger than that of the forefoot buffering part, and generally, different density materials can be used, and the density of the rebound part 3 is higher than that of the forefoot buffering part, such as TPU, and different density foaming materials can be mixed in different proportions to form elastic parts with different densities. There is a certain height difference between the two, so that when the forefoot of the sole 1 is subjected to foot pressure, the forefoot buffering part with a smaller density is first buffered until the sole of the foot contacts with the rebound part 3, and then the rebound part 3 with better rebound performance provides walking assistance. The utility model also provides an embodiment of using an air bag as a forefoot cushioning portion, referring to Figure 1 and Figure 2As shown, it is a specific embodiment 1 that uses the forefoot airbag 2 as the forefoot buffer part. The forefoot airbag 2 and the rebound part 3 are arranged in the toe joint area. The rebound part 3 is arranged on the front side of the forefoot airbag 2. When the forefoot touches the ground, the area from the first to the fifth toe joints biased towards the arch of the foot is mainly stressed, so the forefoot buffer part is arranged in this area. When the forefoot leaves the ground, the area from the first to the fifth toe joints biased towards the toes is the main stress-bearing area, so the rebound part 3 is arranged on the corresponding area. The rebound part 3 can be adopted Figure 1 The cylindrical elastic support column 301 shown in FIG. Figure 2 As shown, the rebound part 3 and the forefoot buffer part can be fixed in the forefoot placement groove 4, the midsole 6 is arranged above the forefoot placement groove 4, and the upper end surface of the forefoot airbag 2 is fixed to the midsole 6. The principle of embodiment 1 is similar to that of the buffer part made of elastic material.

[0024] In the above embodiment 1, referring to Figure 1 and Figure 2 As shown, the heel cushioning part is also included. Preferably, the heel cushioning part includes a heel airbag 7, which is fixed in the heel placement groove 5. The upper end surface of the heel airbag 7 is fixed to the midsole 6. The forefoot airbag 2 and the heel airbag 7 are connected by a thinner air tube 9 arranged around the airbag. The heel airbag 7 and the forefoot airbag 2 are filled with an appropriate amount of gas. The heel airbag 7 is used for cushioning when the heel touches the ground. At the same time, the pressure in the heel airbag 7 rises so that the gas flows to the forefoot airbag 2. The thin air tube 9 can prolong the time for the gas to transfer from the heel airbag to the forefoot airbag 2 to maintain a certain pressure of the heel airbag 7 for cushioning. When the heel touches the ground, the center of gravity of the human body moves from the heel to the forefoot, and then the forefoot touches the ground. At this time, the forefoot airbag 2 is filled and the pressure is relatively large, which can effectively cushion the impact force of the forefoot. Then the heel is lifted, and the gas in the forefoot airbag 2 flows to the heel airbag 7. The volume of the forefoot airbag 2 is further reduced, and the rebound part 3 plays a major supporting role. The larger density and hardness of the rebound part 3 can provide better rebound, which helps walking. In this embodiment 1, in order to make the forefoot airbag 2 and the heel airbag linked, the amount of gas pre-filled in the forefoot airbag 2 and the heel airbag cannot be too much. After the gas in the heel airbag 7 is transferred to the forefoot airbag 2, the heel cushioning is insufficient. Figure 1 As shown, one way is to set radial elastic reinforcing ribs 8 on the heel for auxiliary cushioning, and the height of the reinforcing ribs or part of the reinforcing ribs is slightly lower than the height of the heel airbag.

[0025] Reference Figure 3 As shown, a specific embodiment 2 of the utility model is basically the same as embodiment 1, except that the forefoot airbag 2 covers the forefoot part of the sole 1, and a plurality of through holes are arranged in the forefoot airbag 2. The through holes penetrate the forefoot airbag 2 but are not connected to the internal space of the airbag, and the elastic support column 301, i.e. the rebound part 3, is arranged in the through hole, and the position of the through hole is arranged in the forefoot extension finger joint area.

[0026] Reference Figure 4 and Figure 5 As shown, the specific embodiment 3 of the utility model is basically the same as the embodiment 1, except that a U-shaped rebound portion 3 is provided on the outer side of the forefoot airbag 2, and a baffle 10 is provided above the forefoot airbag 2, and the baffle 10 is fixed to the midsole 6 or the insole, referring to Figure 5 As shown, the two sides of the baffle 10 are wider than the width of the front palm airbag, so that the baffle 10 cooperates with the rebound part 3. When the front palm airbag 2 is deformed downward and the height is lower than the upper surface of the rebound part 3, the rebound part 3 supports the baffle 10. The rebound part 3 may include a U-shaped panel, and an elastic support column 301 or a plurality of elastic support columns 302 are arranged below the U-shaped panel. Figure 5 The V-shaped elastic plate is arranged transversely, and the lower side of the elastic plate is fixed on the sole 1. When the elastic plate is compressed, it generates elastic bending deformation and generates a restoring reaction force to provide walking assistance.
