Description

Technical Field

[0001] This utility model belongs to the field of sports shoe support technology, specifically relating to a high-elasticity sports shoe heel support. Background Technology

[0002] With the popularization of sports among the general public, running, as a form of exercise, is becoming increasingly accepted. However, modern sports medicine research shows that strenuous exercise can cause significant damage to human tissues. Many current sports shoes have inelastic heel supports that lack adequate cushioning, making the feet susceptible to injury from external forces. Furthermore, when people wear these shoes, the heel often supports their body weight, causing the shoe to deform under pressure. These shoes are also not convenient to wear and fail to meet practical usage needs. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a high-elasticity heel support for athletic shoes. Through S-shaped and curved spring sheets, the heel slides smoothly into the shoe, facilitating footwear. A reinforced support frame, an X-shaped elastic frame, a V-shaped elastic plate, V-shaped spring sheets, and elastic blocks provide heel support and full heel wrapping while efficiently dissipating force, thus protecting the foot.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-elasticity sports shoe heel support, comprising a shoe support body, the shoe support body comprising an elastic support structure and a reinforcing support structure, the elastic support structure comprising a V-shaped elastic plate, a V-shaped spring sheet inside the V-shaped elastic plate, an S-shaped shoe support spring sheet integrally formed at the upper end of the V-shaped elastic plate, an opening in the middle of the V-shaped elastic plate, and an elastic block inside the opening; the reinforcing support structure comprising an X-shaped elastic frame, a reinforcing hoop frame installed at the bottom and top of the X-shaped elastic frame, and arc-shaped spring sheets installed on the inner sides of both ends of the reinforcing hoop frame.

[0005] As a preferred embodiment, the bottom surface of the V-shaped elastic plate of the elastic support structure is located at the heel position of the outsole, and the top surface of the V-shaped elastic plate is located in the bottom mounting groove at the heel position of the midsole.

[0006] As a preferred embodiment, the S-shaped shoe support spring includes a first arc-shaped portion, a second arc-shaped portion, and a third arc-shaped portion, with the upper and lower ends of the second arc-shaped portion smoothly connected to the first and third arc-shaped portions, respectively.

[0007] As a preferred embodiment, the X-shaped elastic frame is fixed between the outsole and the midsole by a reinforcing hoop frame.

[0008] As a preferred embodiment, the top of the elastic block has an opening that connects to the mounting groove on the bottom of the shoe midsole.

[0009] As a preferred embodiment, the top of the first arc-shaped portion slopes obliquely upward in a direction away from the heel.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1) This utility model uses S-shaped shoe support springs on the elastic support structure and arc-shaped springs at both ends of the reinforcing hoop frame to allow the heel to slide into the shoe smoothly, making it easier to put on shoes; the reinforcing hoop frame is set at the edge of the shoe upper and the inner lining, which, together with the X-shaped elastic frame, forms the support force for the heel when people step on the shoes, making it less prone to large deformation; thus solving the problem that when the heel supports the body weight, it will press and deform the shoe heel, and is not convenient during the wearing process.

[0012] 2) The elastic blocks and V-shaped springs undergo elastic deformation to achieve shock absorption. Just as the foot is about to leave the ground, the V-shaped springs and elastic blocks begin to rebound, generating an elastic force that lifts the heel upward, making it less likely for the athlete to feel excessive fatigue during prolonged exercise and protecting the safety of the foot.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-5 This utility model provides the following technical solution: a high-elasticity sports shoe heel support, including a shoe support body, the shoe support body including an elastic support structure 2 and a reinforcing support structure 3, the elastic support structure 2 including a V-shaped elastic plate 21, a V-shaped spring piece 25 inside the V-shaped elastic plate 21, an S-shaped shoe support spring piece integrally formed at the upper end of the V-shaped elastic plate 21, an opening 27 in the middle of the V-shaped elastic plate 21, and an elastic block 26 inside the opening 27; the elastic block 26 and the V-shaped spring piece 25 achieve shock absorption function, and have a rebound force to drive the heel upward, so that... The system helps athletes avoid excessive fatigue during prolonged exercise and protects the feet. The reinforced support structure 3 includes an X-shaped elastic frame 33 with reinforced retaining ribs 31 installed at the bottom and top. Arc-shaped spring pieces 32 are installed on the inner sides of both ends of the reinforced retaining ribs 31. The S-shaped shoe support spring pieces above the elastic support structure 2 and the arc-shaped spring pieces 32 installed on the inner sides of both ends of the reinforced retaining ribs 31 allow the heel to slide into the shoe smoothly, making it easy to put on shoes and providing comfort when wearing shoes frequently. The system provides efficient force support and full-wrap heel assistance in relieving stress.

[0022] Specifically, the bottom surface of the V-shaped elastic plate 21 of the elastic support structure 2 is set on the heel position of the outsole 1, and the top surface of the V-shaped elastic plate 21 is set in the bottom mounting groove 41 at the heel position of the midsole 4.

[0023] Specifically, the S-shaped shoe support spring includes a first arc-shaped portion 22, a second arc-shaped portion 23, and a third arc-shaped portion 24. The upper and lower ends of the second arc-shaped portion 23 are smoothly connected to the first arc-shaped portion 22 and the third arc-shaped portion 24, respectively. When the first arc-shaped portion 22 is subjected to force, the second arc-shaped portion 23 will deform and expand outward due to the force. The heel slides down the arc-shaped surface and smoothly passes through the expanded second arc-shaped portion 23, thereby sliding into the third arc-shaped portion 24 to complete the shoe-wearing action.

[0024] Specifically, the X-shaped elastic frame 33 is fixed between the outsole 1 and the midsole 4 by a reinforcing hoop frame 31; the reinforcing hoop frame 31 is provided at the edge of the upper and the lining to work with the X-shaped elastic frame 33 to form a support force for the heel when people wear the shoes, making it less prone to large deformation.

[0025] Specifically, the top of the elastic block 26 has an opening 27 that connects to the mounting groove 41 at the bottom of the shoe midsole 4.

[0026] Specifically, the top of the first arc-shaped portion 22 is inclined upwards in a direction away from the heel; the first arc-shaped portion 22, the second arc-shaped portion 23 and the third arc-shaped portion 24 are all located between the upper and the inner lining of the heel; the reinforcing rib frame 31 and the X-shaped elastic frame 33 are located between the upper and the inner lining of the heel.

[0027] The working principle and usage process of this utility model are as follows: During assembly, the elastic support structure 2 is installed on the heel position of the outsole 1, and the midsole 4 is installed on the elastic support structure 2 through the mounting groove 41. The X-shaped elastic frame 33 is fixed between the outsole 1 and the midsole 4 through the reinforcing hoop frame 31. Then, the heel counter and internal force interlayer are assembled on the elastic support structure 2 and the reinforcing support structure 3 to form an elastic heel.

[0028] During shoe-wearing, the S-shaped shoe support spring above the elastic support structure 2 and the curved springs 32 installed on the inner sides of both ends of the reinforcing hoop frame 31 allow the heel to slide into the shoe, completing the shoe-wearing action. This provides comfort when frequently putting on shoes. When the heel slides into the third curved part 24, the expansion force acting on the second curved part 23 disappears instantly, and the second curved part 23 also instantly returns to its original shape due to the rebound force, locking the heel and making it difficult to pull out, thus achieving the effect of preventing the shoe heel from falling off. Furthermore, the force support and full-wrap heel assistance in relieving stress are highly efficient. The reinforcing hoop frame 31, along with the X-shaped elastic frame 33, are set at the edges of the upper and lining to prevent significant deformation. This solves the problem of the heel deforming when supporting body weight while wearing shoes, and the lack of convenience during the wearing process.

[0029] After putting on the shoes, the heel presses down on the midsole 4, exerting a downward force on the V-shaped elastic plate 21. During movement, the sole experiences a downward force, causing the elastic block 26 to deform elastically, quickly absorbing some of the external pressure and forming primary shock absorption. Simultaneously, the V-shaped elastic plate 21 and V-shaped spring plate 25 also begin to deform elastically, accumulating the remaining external force and forming secondary shock absorption. Just as the foot is about to leave the ground, the V-shaped elastic plate 21, V-shaped spring plate 25, and elastic block 26 begin to rebound, generating an elastic force that lifts the heel upward, preventing runners from experiencing excessive fatigue during long runs and protecting the foot. This gives the shoe support its shock absorption, elastic recovery, and protective functions.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
