TECHNICAL FIELD

[0001] The present application relates to the field of shoe design, in particular to a metal support plate structure for shoes. BACKGROUND

[0002] Shoes are a necessity in people's daily life, and can be divided into leisure shoes, sports shoes, travel shoes and safety shoes according to use; at present, most of the high-end running shoes on the market will embed carbon fiber plates in the shoe sole, and the design of the carbon plate shoes helps to provide better rebound and acceleration ability, so that the runner can save more energy during running, thereby improving the running efficiency.

[0003] However, during the processing and manufacturing of the carbon fiber plate, a series of processes such as fiber pretreatment, impregnation molding, curing, post-molding processing, mold making, cutting impregnation, high-temperature curing molding and polishing treatment are required, and the processing process is relatively complex and time-consuming, so the cost of the carbon fiber plate is relatively high, thereby causing the price of the shoes to be generally high, which is a heavy burden on the consumer's purchasing power, and needs to be improved. CONTENT OF THE INVENTION

[0004] Therefore, the present application provides a metal support plate structure for shoes, which is made of a lightweight metal material to replace the carbon fiber plate in the shoe sole, which is conducive to reducing the overall price of the shoes and reducing the burden on consumers.

[0005] The metal support plate structure for shoes provided by the present application adopts the following technical scheme:

[0006] A metal support plate structure for shoes, comprising a plate body provided in a shoe sole, the plate body being made of a lightweight metal material with a density less than 5g / cm 3 , the plate body being provided with a hollow mesh structure, and the hollow ratio of the plate body being 50% to 90%.

[0007] By using the above technical scheme, the metal support plate is made of a lightweight metal material with a density less than 5g / cm 3 , which has high strength and rigidity, and can provide support, rebound and acceleration ability after being installed in the shoe sole instead of the carbon fiber plate, so that the runner can save more energy during running; since the lightweight metal material can be processed and formed at one time by casting, extrusion or 3D printing, the processing process is more simple and convenient, and the production cost is lower, which is conducive to reducing the overall price of the shoes and reducing the burden on consumers.

[0008] It should be noted that the weight of the support plate made of lightweight metal material is greater than that of the carbon fiber plate under the same volume, so the hollow mesh structure is arranged on the plate body to realize the lightweight design of the metal support plate, so that the shoe sole can be kept light after the support plate is embedded in the shoe sole, and the wearer can run and exercise conveniently.

[0009] Optionally, the plate body is made of titanium alloy material.

[0010] By adopting the above technical scheme, the carbon fiber plate of the shoe sole with the embedded carbon fiber plate may be plastically deformed after being used for a period of time, which affects the comfort of the shoe in subsequent wearing. The titanium alloy used in the application is a memory metal, and the plate body made of titanium alloy material has good recovery ability, which can still maintain the good supporting effect of the shoe sole on the human foot under long-term wearing of the shoe, thereby making the shoe have long-term wearing comfort, which is conducive to popularization and use.

[0011] Optionally, the plate body is integrally formed by a 3D printing process.

[0012] By adopting the above technical scheme, considering that the plate body has a hollow mesh structure, the plate body of the required shape can be formed at one time by the 3D printing process, which has the advantages of fast and convenient production process, and is conducive to reducing the production cost of the plate body and thereby reducing the overall price of the shoe.

[0013] Optionally, when the plate body is formed in the shoe sole, the hollow mesh structure is arranged away from the exposed part of the plate body.

[0014] By adopting the above technical scheme, after the plate body is formed in the shoe sole, it may be partially exposed to the shoe sole surface. By arranging the hollow mesh structure away from the exposed part of the plate body, the support effect of the whole exposed part on the shoe sole is better, and the appearance of the shoe sole is also guaranteed.

[0015] Optionally, the plate body has a forefoot part and a heel part, and the forefoot part is curved to form a curved segment towards the human foot.

[0016] By adopting the above technical scheme, by curving the forefoot part of the plate body to form a curved segment, the curved segment is curved towards the human foot, which is more helpful to overcome the pressure from the human foot and reduce the possibility of deformation of the plate body under pressure, and is conducive to keeping the shoe sole fit the human foot, which has extremely high wearing comfort.

[0017] Optionally, the front edge of the plate body is provided with a notch, and the forefoot part of the plate body forms two toe pressure deformation parts through the notch.

[0018] By adopting the technical scheme, the two toe pressure deformation portions are formed on the front palm portion of the plate body by the notch, and the two toe pressure deformation portions can be respectively pressed and deformed by the thumb and the other four fingers, so that different sports scenes can be adapted, and the wearing comfort of the shoes is further improved.

[0019] Optionally, the rear edge of the plate body is provided with a heel avoiding opening.

[0020] By adopting the technical scheme, the heel avoiding opening can weaken the supporting effect of the plate body on the human heel, so that people do not feel uncomfortable when walking and the heel is stepped on the ground, and the wearing comfort of the shoes is improved.

[0021] Optionally, the plate body is provided with a reinforcing rib, and the reinforcing rib is protrudingly arranged towards the foot direction.

[0022] By adopting the technical scheme, the reinforcing rib can enhance the structural strength of the plate body, reduce the possibility of breaking of the plate body under the long-term pressure of the human foot, and maintain good service life.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. By using a metal support plate instead of a carbon fiber plate, the support plate installed inside the shoe sole can also provide support, rebound and acceleration capacity, so that the runner can save more energy during running; since the processing process of the metal support plate is more simple, the production cost is lower, which is beneficial to reduce the overall price of the shoes and reduce the burden of consumers;

[0025] 2. By providing the plate body with a hollow mesh structure, the lightweight design of the metal support plate can be realized, so that the shoe sole can remain light after the support plate is embedded in the shoe sole, which is convenient for the wearer to run and exercise;

[0026] 3. By providing the reinforcing rib, the structural strength of the plate body can be enhanced, the possibility of breaking of the plate body under the long-term pressure of the human foot can be reduced, and good service life can be maintained. BRIEF DESCRIPTION OF DRAWINGS

[0030] The following description will be made in conjunction with the accompanying drawings Figures 1-2 The application is further described in detail.

[0031] The embodiment of the application discloses a metal support plate structure for shoes.

[0032] Referring to Figure 1 A metal support plate structure for shoes, comprising a plate body 1, the plate body 1 is made of a lightweight metal material with a density less than 5 g / cm3, which can be titanium alloy, aluminum alloy or magnesium lithium alloy, etc. In this embodiment, the plate body 1 is made of titanium alloy material. Since titanium alloy is a memory metal, the plate body 1 made of titanium alloy material has good recovery ability. By arranging the plate body 1 between the outsole and the midsole of the sole or directly on the outsole surface of the sole body, the plate body 1 can replace the carbon fiber plate to provide support, rebound and acceleration for the human foot, and still maintain the good support effect of the sole on the human foot in the case of long-term wearing of the shoes.

[0033] The plate body 1 is provided with a hollow mesh structure 2 on the surface, which is used to realize the lightweight design of the plate body 1. The hollow proportion of the plate body 1 is 50% to 90%, and the hollow mesh design can be increased as much as possible to reduce the weight of the plate body 1 and ensure the lightness of the sole under the condition that the plate body 1 will not be broken. It should be noted that for some products, the plate body 1 is formed inside the sole, and the plate body 1 will be partially exposed on the outsole surface of the plate body 1. In this embodiment, the hollow mesh structure 2 is avoided from the exposed part of the plate body 1, and the whole exposed part can provide better support for the sole.

[0034] In addition, the plate body 1 is provided with an integrally formed reinforcing rib 3 on the surface, the reinforcing rib 3 is protrudingly arranged towards the foot direction, and the extension direction of the reinforcing rib 3 is the same as the extension direction of the plate body 1. The arrangement of the reinforcing rib 3 can increase the hollow mesh design proportion while enhancing the structural strength of the plate body 1, effectively reducing the risk of collapse of the plate body 1 due to long-term stress.

[0035] The plate body 1 made of titanium alloy material can be processed by die forging, extrusion molding or casting molding, etc. However, considering the hollow mesh structure 2 and the reinforcing rib 3 of the plate body 1 in this embodiment, the 3D printing mode is adopted for integrated processing, which is beneficial to the rapid forming of the plate body 1, can reduce the production price of the plate body 1, and further reduce the overall price of the shoes.

[0036] Referring to Figure 2The plate body 1 in the embodiment is structurally composed of a forefoot part 11, an arch part 13 and a heel part 12 connected in sequence; the forefoot part 11 is arranged to be curved towards the human foot, forming a curved section 111, which can better overcome the pressure from the human foot and reduce the possibility of deformation of the plate body 1 under pressure, thus helping to keep the shoe sole in close contact with the human foot.

[0037] In addition, returning to Figure 1 , the front side edge of the forefoot part 11 is provided with a notch 14, which separates the forefoot part 11 of the plate body 1 into two toe pressure deformation parts 15, which can be respectively pressed and deformed by the thumb and the remaining four fingers, respectively, and can be suitable for different sports scenes, thus helping to further improve the wearing comfort of the shoes.

[0038] The rear side edge of the heel part 12 is provided with a heel avoiding opening 16, which can weaken the supporting effect of the plate body 1 on the human heel, so that people will not feel uncomfortable when walking and the heel is stepped on the ground, thus helping to improve the wearing comfort of the shoes.

[0039] The implementation principle of the metal support plate structure for shoes according to the embodiment of the application is as follows:

[0040] By using the above technical solution, the metal support plate made of lightweight metal material with a density less than 5g / cm3 is used, and the support plate also has high strength and rigidity, which can provide support, rebound and acceleration capacity after being installed inside the shoe sole instead of the carbon fiber plate, so that the runner can save more energy during running; since the lightweight metal material can be processed into a one-time forming mode by casting, extrusion or 3D printing, the processing process is more simple and the production cost is lower, which is conducive to reducing the overall price of the shoes and reducing the burden of consumers.

[0041] It should be noted that the weight of the support plate made of lightweight metal material is greater than that of the carbon fiber plate under the same volume, so the application is provided with a hollow mesh structure on the plate body, which can realize the lightweight design of the metal support plate, so that the shoe sole can be kept light after the support plate is embedded in the shoe sole, which is convenient for the wearer to run and exercise.

[0042] The above is the preferred embodiment of the application, which does not limit the protection scope of the application, therefore: any equivalent changes made according to the structure, shape and principle of the application shall be covered within the protection scope of the application.
