Description

Technical Field

[0001] This utility model relates to the field of high-heeled shoe midsole technology, and in particular to a high-heeled shoe midsole with a metal reinforcement structure. Background Technology

[0002] The midsole is a crucial component of high heels, providing cushioning and support. Traditional high heel midsoles typically use a single, longitudinally placed strip of metal as a support structure. However, relying solely on this strip results in poor lateral stability and torsional stiffness control, making the shoe prone to deformation and increasing the risk of ankle sprains. Some high heel midsoles use a single sheet of metal to enhance support, lateral stability, and torsional stiffness control. However, if the metal sheet is too thin, it fails to improve these aspects; if it is too thick, it increases bulk and weight, leading to poor comfort. Therefore, improvements are necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a high-heeled shoe midsole with a metal-reinforced structure, which improves lateral stability and torsional stiffness control, reduces the risk of ankle sprains, enhances stability, and simultaneously reduces thickness and weight, thereby improving comfort.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-heeled shoe midsole with a metal reinforcement structure, comprising a midsole body, which includes a cushioning layer, an elastic layer, and a support layer arranged sequentially from top to bottom. A metal reinforcement component is disposed between the elastic layer and the support layer. The front part of the midsole body is designated as the forefoot portion, the middle part as the arch portion, and the rear part as the heel portion. The metal reinforcement component includes an X-shaped frame and a T-shaped frame connected to the rear of the X-shaped frame. The X-shaped frame is disposed at the heel portion of the midsole body, and the T-shaped frame is disposed at the heel portion of the midsole body.

[0005] The X-frame includes a first metal strip and a second metal strip, which are arranged intersectingly, and the middle of the first metal strip is fixedly connected to the middle of the second metal strip.

[0006] The T-shaped frame includes a third metal strip and a fourth metal strip. The left and right ends of the third metal strip are fixedly connected to the rear ends of the first and second metal strips, respectively, and the front end of the fourth metal strip is fixedly connected to the middle of the third metal strip.

[0007] In a further technical solution, the first metal strip has a first groove with its opening facing downward in the middle, and the second metal strip has a second groove with its opening facing downward in the middle. The middle of the second metal strip is embedded in the first groove, and the middle of the first metal strip is embedded in the second groove. The first metal strip and the second metal strip are fixedly connected as a whole by riveting or welding.

[0008] In a further technical solution, the rear ends of the lower surfaces of the first metal strip and the second metal strip each extend inward to form a connecting lug, and the two ends of the third metal strip are respectively fixedly connected to the two connecting lugs by riveting or welding. The upper surface of the third metal strip is aligned with the upper surfaces of the first metal strip and the second metal strip.

[0009] In a further technical solution, the third metal strip is an arc-shaped third metal strip, which is bent toward one side of the X-shaped frame.

[0010] In a further technical solution, the fourth metal strip has at least one connecting hole for connecting the shoe heel, and the corresponding support layer has a through hole at the position of the connecting hole.

[0011] In a further technical solution, the first metal strip and the second metal strip each have at least one vent hole.

[0012] In a further technical solution, the outer surfaces of the X-shaped frame and the T-shaped frame are coated with an anti-corrosion layer.

[0013] In a further technical solution, the lower surface of the elastic layer is provided with a downwardly protruding extension at the position of the forefoot, the front end of the support layer is located on the front side of the arch and connected to the rear side of the extension, and the lower surface of the extension is aligned with the lower surface of the support layer.

[0014] In a further technical solution, the upper surface of the buffer layer is provided with an upwardly protruding anti-slip protrusion at the position of the forefoot, and the anti-slip protrusion corresponds to the connection between the metatarsal and phalangeal bones.

[0015] In a further technical solution, the buffer layer is a buffer layer made of PU material, the elastic layer is an elastic layer made of TPU material, and the support layer is a support layer made of glass fiber reinforced nylon.

[0016] The advantages of this invention compared to existing technologies are as follows: by covering the arch and heel with the X-frame and T-frame respectively, the coverage area of ​​the metal reinforcement structure is increased, thereby improving lateral stability and torsional stiffness control and preventing rollover and ankle sprains; the frame structure provides support, making it lighter and more comfortable than a single metal plate; and the extension connects with the support layer, improving the elastic bending ability of the forefoot and enhancing walking comfort.

[0026] 51 Forefoot, 52 Arch, 53 Heel. Detailed Implementation

[0027] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0028] A high-heeled shoe midsole with a metal-reinforced structure, such as Figures 1 to 3As shown, the shoe includes a midsole body, which comprises a cushioning layer 1, an elastic layer 2, and a support layer 3 arranged sequentially from top to bottom. A metal reinforcing component 4 is disposed between the elastic layer 2 and the support layer 3. The front part of the midsole body is designated as the forefoot portion 51, the middle part as the arch portion 52, and the rear part as the heel portion 53. The metal reinforcing component 4 includes an X-shaped frame 41 and a T-shaped frame 42 connected to the rear of the X-shaped frame 41. The X-shaped frame 41 is disposed at the heel portion 53 of the midsole body, and the T-shaped frame 42 is disposed at the rear of the midsole body. The heel portion 53 of the body, the X-shaped frame 41 includes a first metal strip 411 and a second metal strip 413, the first metal strip 411 and the second metal strip 413 are arranged to cross each other, the middle part of the first metal strip 411 is fixedly connected to the middle part of the second metal strip 413, the T-shaped frame 42 includes a third metal strip 421 and a fourth metal strip 422, the left and right ends of the third metal strip 421 are fixedly connected to the rear ends of the first metal strip 411 and the second metal strip 413 respectively, and the front end of the fourth metal strip 422 is fixedly connected to the middle part of the third metal strip 421. Traditional high-heeled shoe midsoles rely on a single longitudinally placed metal strip as a support, resulting in poor lateral stability and torsional stiffness control, which can easily lead to shoe deformation and ankle sprains. High-heeled shoe midsoles made of a single sheet of metal are heavy and uncomfortable, while those made of carbon fiber are expensive. This invention, however, uses an X-shaped frame 41 and a T-shaped frame 42 to cover the arch 52 and heel 53 respectively, increasing the coverage area of ​​the metal reinforcement structure. This improves lateral stability and torsional stiffness control, preventing lateral rollovers and ankle sprains. The frame structure provides support and is lighter and more comfortable than a single sheet of metal.

[0029] Specifically, the first metal strip 411 has a downward-facing first groove 412 in its middle, and the second metal strip 413 has a downward-facing second groove 414 in its middle. The middle of the second metal strip 413 is embedded in the first groove 412, and the middle of the first metal strip 411 is embedded in the second groove 414. The first metal strip 411 and the second metal strip 413 are fixedly connected as a whole by riveting or welding. The first groove 412 and the second groove 414 interlock the first metal strip 411 and the second metal strip 413, which not only improves the connection strength but also keeps the first metal strip 411 and the second metal strip 413 on the same horizontal plane, thereby reducing the thickness of the metal reinforcing component 4 and improving flatness.

[0030] Specifically, the rear ends of the lower surfaces of the first metal strip 411 and the second metal strip 413 each extend inward to form a connecting lug 415. The two ends of the third metal strip 421 are respectively fixedly connected to the two connecting lugs 415 by riveting or welding. The upper surface of the third metal strip 421 is aligned with the upper surfaces of the first metal strip 411 and the second metal strip 413. The connecting lugs 415 connect the X-shaped frame 41 and the T-shaped frame 42, facilitating assembly and ensuring that the X-shaped frame 41 and the T-shaped frame 42 are on the same plane, preventing them from overlapping, further reducing thickness, and improving flatness.

[0031] Specifically, the third metal strip 421 is an arc-shaped third metal strip 421, which is bent towards one side of the X-shaped frame 41. The arc-shaped third metal strip 421 can increase the length of the third metal strip 421, increase the support coverage area, and further increase the support.

[0032] Specifically, the fourth metal strip 422 has at least one connecting hole 423 for connecting the heel, and the corresponding support layer 3 has a through hole at the position of the connecting hole 423. The fourth metal strip 422 covers the heel part 53, and the connecting hole 423 facilitates connection to the heel, which is convenient for production and assembly.

[0033] Specifically, the first metal strip 411 and the second metal strip 413 are each provided with at least one vent hole 43. By increasing the breathability through the vent holes 43, the material and weight of the first metal strip 411 and the second metal strip 413 are reduced, thereby improving breathability while reducing weight and cost.

[0034] Specifically, the outer surfaces of the X-frame 41 and T-frame 42 are coated with an anti-corrosion layer. This anti-corrosion coating protects the metal reinforcing components 4 from moisture and liquid corrosion, thus improving durability.

[0035] Specifically, the lower surface of the elastic layer 2 has a downwardly protruding extension 21 located at the forefoot portion 51. The front end of the support layer 3 is located on the front side of the arch portion 52 and connected to the rear side of the extension 21. The lower surface of the extension 21 is aligned with the lower surface of the support layer 3. By connecting the extension 21 with the support layer 3, the elastic bending ability of the forefoot portion 51 is improved, thus enhancing walking comfort.

[0036] Specifically, the upper surface of the cushioning layer 1 has an upwardly protruding anti-slip protrusion 11 at the forefoot 51 position, which corresponds to the connection between the metatarsal and phalangeal bones. Because high heels are high and the foot is in a forward-leaning posture, the foot is prone to sliding forward inside the shoe. By setting the anti-slip protrusion 11, the foot is limited, preventing the foot from sliding forward excessively and squeezing the toe of the shoe, thus further improving stability.

[0037] Specifically, the buffer layer 1 is made of PU material, the elastic layer 2 is made of TPU material, and the support layer 3 is made of glass fiber reinforced nylon. The PU material buffer layer 1 is not only soft but also elastic, improving shock absorption. The TPU material elastic layer 2 is not only elastic but also has high strength; together with the buffer layer 1, it further enhances shock absorption and increases comfort. Together with the support layer 3, it further improves structural strength and stability. Glass fiber reinforced nylon, also known as glass fiber reinforced nylon, is a high-performance engineering plastic composite material. By adding glass fibers, the mechanical properties of the original nylon material are improved, reducing weight while giving the support layer 3 higher strength and improved support.

[0038] During production, the first metal strip 411, the second metal strip 413, and the T-shaped frame 42 are first stamped, with the third metal strip 421 and the fourth metal strip 422 being stamped as a single piece. Then, the first metal strip 411 and the second metal strip 413 are welded together. Finally, the third metal strip 421 is welded to the two connecting ears 415. Finally, anti-corrosion material is sprayed to form an anti-corrosion layer, completing the prefabrication of the metal reinforcement component 4. The support layer 3 is formed by injection molding, the elastic layer 2 is formed by TPU foaming, and the buffer layer 1 is formed by PU casting. Finally, the layers are stacked and hot-pressed together.

[0039] Alternatively, after stamping the first metal strip 411, the second metal strip 413, and the T-shaped frame 42, they are first subjected to anti-corrosion treatment, and then each component is spliced ​​on the support layer 3. The metal reinforcing component 4 is connected to the support layer 3 together by riveting, and then the composite elastic layer 2 and the buffer layer 1 are hot-pressed.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
