Description

Technical Field

[0001] This application relates to the field of footwear, and in particular to an impact-resistant children's shoe. Background Technology

[0002] Children are naturally active, frequently running, jumping, and leaping, resulting in a greater impact force on their feet when they land. Children's feet, ankles, knees, and other bones and joints are still developing, and their sole fat pads are thinner, making their cushioning ability weaker. Therefore, children's shoes require higher impact resistance.

[0003] In existing technologies, the impact resistance of children's shoes can be improved by adjusting the sole material (such as EVA material), thereby providing good cushioning and shock absorption and reducing the risk of foot injuries. However, adjusting the sole material has limited effect on improving the impact resistance of the elastic midsole, and new technologies are needed to further enhance the impact resistance of the elastic midsole. Utility Model Content

[0004] In order to improve the impact resistance and comfort of children's shoes, this application provides an impact-resistant children's shoe.

[0005] This application provides an impact-resistant children's shoe, which adopts the following technical solution: An impact-resistant children's shoe includes an elastic midsole and an upper body, the upper body being fixed to the elastic midsole. The elastic midsole has a longitudinal and a transverse direction perpendicular to each other, and a vertical direction perpendicular to both the longitudinal and transverse directions. The shoe also includes an elastic metal component, which is arranged laterally and embedded in the heel and / or forefoot portion of the elastic midsole, extending longitudinally. The elastic metal component includes an integrally formed first plate and a second plate. Vertically, the first plate is positioned above the second plate, and the second plate is symmetrically positioned on both sides of the first plate. The first plate is arranged laterally, and the second plate is arranged vertically. When the first plate is subjected to a downward force, the first plate forces the second plate to elastically bend and deform.

[0006] By adopting the above technical solution, when a child's foot lands, the child's foot exerts a downward force on the first plate, causing the second plate to bend and deform. That is, by embedding an elastic metal component in the elastic midsole, part of the impact force generated by the child's foot landing is converted into the elastic potential energy of the second plate for storage, thereby weakening the impact force transmitted to the foot, ankle and knee joint, reducing the risk of foot injury to children and improving the comfort of children wearing shoes.

[0007] Optionally, the first plate is an arc-shaped plate, which protrudes upward in the vertical direction; when the first plate is subjected to a downward force, the two ends of the second plate move towards the outer side of the elastic midsole in the horizontal direction.

[0008] By adopting the above technical solution, the first plate is an arc-shaped plate with an upward protrusion; thus, when a child's foot lands on the ground, the arc-shaped first plate is conducive to transmitting the impact force to the second plates on both sides, so as to facilitate the bending deformation of the second plates and store energy.

[0009] Optionally, the second plate is an arc-shaped plate, and in the vertical direction, the second plate protrudes towards the central region of the elastic insole.

[0010] By adopting the above technical solution, the second plate is convex toward the central area of ​​the elastic midsole, which helps to improve the bending deformation of the second plate when the child's foot hits the ground, so that more impact energy can be converted into the elastic potential energy of the second plate.

[0011] Optionally, the second plate has grooves on both sides along the longitudinal direction.

[0012] By adopting the above technical solution, grooves are provided on both sides of the second plate, which helps to improve the bending deformation of the second plate, so that more impact energy can be converted into the elastic potential energy of the second plate.

[0013] Optionally, the elastic metal component further includes a blocking plate, which is disposed on the side of the second plate away from the first plate. The blocking plate is integrally formed with the second plate, and the second plate is vertically arranged.

[0014] By adopting the above technical solution, the blocking plate has a restraining effect on the lower end of the second plate, which is conducive to the bending deformation of the second plate when the child's foot hits the ground.

[0015] Optionally, in the vertical direction, the second plate has a corrugated plate in the middle; when the second plate is subjected to force, the corrugated plate bends and deforms.

[0016] By adopting the above technical solution, the second plate has a corrugated plate in the middle, which facilitates the bending and deformation of the second plate when a child's foot hits the ground.

[0017] Optionally, the first plate is provided with a plurality of first connecting holes spaced apart.

[0018] By adopting the above technical solution, the synergy between the elastic metal component and the elastic midsole is improved by opening a first connecting hole on the first plate.

[0019] Optionally, the second plate is provided with a plurality of second connecting holes spaced apart.

[0020] By adopting the above technical solution, and by opening a second connecting hole on the second plate, the synergy between the elastic metal component and the elastic midsole is improved.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When a child's foot lands, the child's foot exerts a downward force on the first plate, causing the second plate to bend and deform. That is, by embedding an elastic metal component in the elastic midsole, part of the impact force generated by the child's foot landing is converted into the elastic potential energy of the second plate for storage, thereby weakening the impact force transmitted to the foot, ankle and knee joint, reducing the risk of foot injury to children and improving the comfort of children wearing children's shoes. 2. The first plate is an arc-shaped plate with an upward protrusion; thus, when a child's foot hits the ground, the arc-shaped first plate helps to transmit the impact force to the second plates on both sides, which facilitates the bending deformation of the second plates and stores energy. 3. Grooves are provided on both sides of the second plate, which helps to improve the bending deformation of the second plate, so that more impact energy can be converted into the elastic potential energy of the second plate.

[0031] The following is in conjunction with the appendix Figure 1 -8 provides further details regarding this application.

[0032] This application discloses an impact-resistant children's shoe. (See attached embodiment.) Figure 1 The impact-resistant children's shoes include a sole body 1, an upper body 2, and an elastic metal component 3. The sole body 1 includes a wear-resistant outsole 11 and an elastic midsole 12, wherein the elastic midsole 12 is fixed on the wear-resistant outsole 11.

[0033] Reference Figure 1 The upper body 2 is fixed to the elastic midsole 12, which has a longitudinal and transverse direction perpendicular to each other, and a vertical direction perpendicular to both the longitudinal and transverse directions. The elastic midsole 12 can be made of foamed materials such as EVA or PU to improve its cushioning and shock absorption performance, thereby enhancing the shoe's impact resistance. In this embodiment, the elastic midsole 12 is made of EVA material. In this embodiment, the abrasion-resistant outsole 11 is made of abrasion-resistant rubber.

[0034] Reference Figure 2 and Figure 3 The elastic metal component 3 is arranged laterally and embedded in the heel and / or forefoot of the elastic midsole 12. The elastic metal component 3 can be made of a metal material with bending and deformation capabilities, such as titanium alloy or nickel alloy. In this embodiment, the elastic metal component 3 is made of titanium alloy and is integrally formed using 3D printing technology. After the elastic metal component 3 is manufactured, it can be placed in a foaming mold of the shoe sole; then, foaming material is added to the foaming mold, and the foaming material foams in the mold to form the elastic midsole 12; thus, the elastic metal component 3 is embedded in the elastic midsole 12.

[0035] In this embodiment, the elastic metal component 3 is embedded in the heel portion of the elastic midsole 12; in another embodiment, the elastic metal component 3 is embedded in the forefoot portion of the elastic midsole 12; in yet another embodiment, the elastic metal component 3 is embedded in both the heel and forefoot portions of the elastic midsole 12.

[0036] Reference Figure 4 and Figure 5The elastic metal component 3 extends longitudinally and includes an integrally formed first plate 31, a second plate 32, and a blocking plate 33. Vertically, the first plate 31 is positioned above the second plate 32, and the second plate 32 is symmetrically positioned on both sides of the first plate 31. The first plate 31 is horizontally positioned, and the second plate 32 is vertically positioned. The blocking plate 33 is positioned on the side of the second plate 32 away from the first plate 31. The blocking plate 33 and the second plate 32 are integrally formed, and the second plate 32 is vertically positioned.

[0037] Reference Figure 4 and Figure 5 The first plate 31 is an arc-shaped plate, and it protrudes upwards vertically. Several first connecting holes 311 are spaced apart on the first plate 31. When the first plate 31 is subjected to a downward force, the two ends of the second plate 32 move outwards towards the elastic insole 12 laterally. The first connecting holes 311 on the first plate 31 improve the connection strength between the elastic metal component 3 and the elastic insole 12, enhancing their synergy. Furthermore, the first plate 31 also has fixing holes 312, the diameter of which is larger than the diameter of the first connecting holes 311. When the elastic metal component 3 is placed in the molding die, a support rod in the die is used to block the fixing holes 312, thus fixing the position of the elastic metal component 3 within the mold cavity.

[0038] Reference Figure 4 and Figure 5 The second plate 32 is an arc-shaped plate that protrudes vertically toward the central region of the elastic insole 12. Several second connecting holes 321 are spaced apart on the second plate 32. When the first plate 31 is subjected to a downward force, it forces the second plate 32 to elastically bend and deform. By providing the second connecting holes 321 on the second plate 32, the connection strength between the elastic metal component 3 and the elastic insole 12 is improved, thus enhancing their synergy.

[0039] Reference Figure 4 and Figure 5 The blocking plate 33 is disposed on the side of the second plate 32 away from the first plate 31. The blocking plate 33 and the second plate 32 are integrally formed, and the second plate 32 is vertically arranged. A number of third connecting holes 331 are opened at intervals on the blocking plate.

[0040] The implementation principle of an impact-resistant children's shoe according to an embodiment of this application is as follows: Reference Figure 2When a child's foot lands, the child's foot exerts a downward force on the first plate 31. The curved shape of the first plate 31 facilitates the transmission of the impact force to the second plates 32 on both sides, thus promoting the bending deformation of the second plates 32. The second plates 32 convert part of the impact energy into their elastic potential energy. The blocking plate 33 constrains the lower end of the second plates 32, thereby promoting the bending deformation of the second plates 32 when the child's foot lands.

[0041] Reference Figure 2 That is, by embedding an elastic metal component 3 in the elastic midsole 12, part of the impact force generated by the child's foot landing is converted into the elastic potential energy of the second plate 32 for storage, thereby weakening the impact force transmitted to the foot, ankle and knee joint, reducing the risk of foot injury to children and improving the comfort of children wearing children's shoes.

[0042] Example 2 The difference between Example 2 and Example 1 is as follows: Reference Figure 6 Along the longitudinal direction, the second plate 32 has grooves 322 on both sides. These grooves 322 on both sides of the second plate 32 facilitate bending deformation, allowing more impact energy to be converted into elastic potential energy. This reduces the impact force transmitted to the feet, ankles, and knees, lowering the risk of foot injuries in children and improving the comfort of children's shoes. Example 3 The difference between Example 3 and Example 1 is as follows: Reference Figure 7 and Figure 8 Vertically, the second plate 32 has a corrugated plate 323 in the middle; when the second plate 32 is subjected to force, the corrugated plate 323 bends and deforms. The corrugated plate 323 in the middle of the second plate 32 facilitates the bending and deformation of the second plate 32 when a child's foot lands; thereby reducing the impact force transmitted to the foot, ankle and knee joint, reducing the risk of foot injury to children, and improving the comfort of children wearing children's shoes.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
