Abstract
Description
Technical Field
[0001] This application relates to the technical field of footwear, and in particular to a bending support and a sole having the bending support. Background Technology
[0002] As people's demands for sports performance and comfort continue to increase, optimizing the performance of athletic shoes has become an important research direction in the footwear industry. The support strength of the sole, as a key factor affecting athletic shoe performance, has always received widespread attention.
[0003] In the past, to improve the support strength of the sole, a carbon fiber plate was typically embedded in the sole. This method can enhance the support performance of the sole to a certain extent, ensuring the stability of the shoe during wear.
[0004] However, the manufacturing process of carbon fiber plates involves multiple complex steps. First, the raw materials need to be cut to predetermined dimensions. Next comes the layering process, which often requires multiple repetitions depending on the required number of layers to achieve the desired structural thickness and performance. Afterward, the carbon fiber plate undergoes shaping to obtain the desired form. Then, it goes through cutting and cleaning steps to remove excess material and ensure a clean surface. Finally, adhesive is applied to fix the carbon fiber plate inside the sole. The entire process requires manual intervention at multiple stages, each demanding meticulous operation to ensure the quality of the final product; therefore, further improvements are needed. Utility Model Content
[0005] Therefore, this application provides a bending support member and a shoe sole having the bending support member.
[0006] The present application provides a bending support member and a shoe sole having the bending support member, which adopts the following technical solution:
[0007] A bending support includes a support plate body, which is a 3D printed part. The support plate body includes a middle part corresponding to the arch of the foot and a forefoot support part and a heel support part respectively disposed at both ends of the middle part. The middle part arches upward to form a first arc-shaped surface, the forefoot support part is concave downward to form a second arc-shaped surface, and the heel support part arches upward to form a third arc-shaped surface, so that the middle part, the forefoot support part and the heel support part are continuously bent relative to the foot.
[0008] By adopting the above technical solution, the middle part, the forefoot part and the heel support part are respectively provided with a first arc surface, a second arc surface and a third arc surface. These three are arranged in a continuous curved shape corresponding to the foot. Since the support plate body is a 3D printed part, it can fit the contour of the foot well and is more in line with the ergonomic principle. Due to the 3D printed part, it can reduce complex processes such as built-in carbon plates, reduce manpower and product quality problems.
[0009] This design not only effectively distributes pressure on the feet, reducing excessive localized pressure, but also enhances support for the arch, forefoot, and heel, improving stability and comfort during walking or exercise. Specifically, during walking, when the forefoot lands, the foot applies a downward force to the forefoot support. As the body's center of gravity shifts to the forefoot, the heel support applies a force to the heel. As the body's center of gravity moves further forward, the force exerted on the heel by the support plate gradually changes from upward to forward. The support plate rotates with the forefoot as a fulcrum, with one end near the toes pressing down and the other end near the heel lifting. This transforms the pressure exerted by the forefoot on the support plate into a thrust that lifts the heel, reducing the force required to lift the heel and making walking easier, further improving comfort when wearing these casual shoes.
[0010] Preferably, the forefoot support portion and / or heel support portion is provided as an inverted U-shaped plate, and the opening of the inverted U-shaped plate is located close to or far from the middle portion.
[0011] By adopting the above technical solution, the forefoot support and / or heel support is set as an inverted U-shaped plate. The opening of the inverted U-shaped plate is close to or far from the middle part, which can enhance the support strength and stability of this part. At the same time, it can make reasonable use of space and optimize the internal structure layout of the sole while meeting the support requirements.
[0012] Preferably, the opening of the U-shaped plate is closed, so that the cross-section of the forefoot support and / or the heel support is annular.
[0013] By adopting the above technical solution, the forefoot support and / or heel support is set as an inverted U-shaped plate, and the opening of the inverted U-shaped plate is closed so that its cross-section is set in a ring shape. This enhances the structural stability and support strength of the forefoot support and / or heel support, better disperses the pressure applied by the foot, reduces local stress concentration, and improves support performance, thereby more effectively improving the support strength and comfort of the sole for the foot.
[0014] Preferably, the cross-section of the middle portion along its width direction is wavy.
[0015] By adopting the above technical solution, the cross-section of the middle part is wavy along the width direction, which can enhance the structural strength of the middle part. When subjected to external force, it can better disperse stress and is not easily deformed or damaged, thus providing more effective stable support for the arch of the foot. At the same time, the wavy structure can also adapt to the movement of the foot to a certain extent, improving the wearer's comfort.
[0016] Preferably, the upper and / or lower surfaces of the middle portion are provided with longitudinal reinforcing ribs.
[0017] By adopting the above technical solution, setting longitudinal reinforcing ribs on the upper and / or lower surfaces of the middle part can improve the strength of the middle part; and the longitudinal reinforcing ribs extend to the forefoot support and / or heel support, further enhancing the strength of the forefoot support and heel support, thereby comprehensively improving the structural strength of the entire bending support.
[0018] Preferably, the support plate body is hollowed out.
[0019] By adopting the above technical solution, the support plate body is hollowed out, which can further reduce the weight of the support component.
[0020] Preferably, the support plate body is made of lightweight metal.
[0021] By adopting the above technical solution, the support plate body made of lightweight metal has both the strength of metal support and a relatively light weight.
[0022] A shoe sole having the bending support includes a sole body and a bending support built into the sole body.
[0023] Preferably, the side wall of the sole body is provided with a through groove, the through groove including a first through groove corresponding to the forefoot support part and a second through groove corresponding to the heel support part.
[0024] By adopting the above technical solution, the sidewall of the sole body has a first through groove corresponding to the forefoot support and a second through groove corresponding to the heel support, which enables air circulation inside the sole, achieving a breathable effect and potentially reducing the weight of the sole. Simultaneously, the corresponding forefoot and heel support sections provide deformation space for these sections, thereby improving the support effect of the support component.
[0025] In summary, this utility model has the following beneficial effects:
[0026] 1. The bending support is integrally molded and continuously bent to correspond to the foot shape, which can adapt to the shape of the foot, effectively reduce the pressure on the foot during exercise, reduce the risk of injury, and improve the stability and comfort of exercise;
[0027] 2. The support plate is made of lightweight metal and is a 3D printed part. Compared with traditional carbon plates, it has both the strength of metal support and a lighter weight, while reducing complex manufacturing processes, saving manpower and time, and reducing production costs and production cycle.
[0028] 3. The support plate body is hollowed out, which can further reduce the weight of the support components. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-17 This application will be described in further detail below.
[0048] This application discloses a bending support member and a shoe sole having the bending support member.
[0049] Example 1:
[0050] A bending support member, as shown in the figure Figure 1 The system includes a support plate body 1. In this embodiment, the support plate body 1 is made of lightweight metal, specifically an ultralight / light metal with a density of less than 5. It can be a titanium alloy or a high-strength aluminum alloy. Such metals have both the strength of metal support and a relatively light weight. The support plate body 1 is a 3D printed part, which can more accurately control the shape and structure of the support plate body 1, realize complex design requirements, and reduce the relatively complex manufacturing process.
[0051] Furthermore, in order to reduce the burden on the feet caused by the support member, in this embodiment, the support plate body 1 is hollowed out. The hollowing ratio is designed according to the required support strength and shoe shape. The hollowing shape can be a circle, square, rhombus or other regular or irregular shapes.
[0052] Reference Figure 1 , Figure 2Specifically, the support plate body 1 includes a middle part 2 corresponding to the arch of the foot, and a forefoot support part 3 and a heel support part 4 respectively located at both ends of the middle part 2. The middle part 2 is arched to form a first arc-shaped surface 21. The forefoot support part 3 is slightly concave to form a second arc-shaped surface 31, while the heel support part 4 is slightly arched to form a third arc-shaped surface 41. The two ends of the first arc-shaped surface 21 transition towards the first arc-shaped surface 21 and the second arc-shaped surface 31, so that the middle part 2, the forefoot support part 3 and the heel support part 4 are continuously curved to conform to the foot shape, thereby improving fit and comfort.
[0053] In this embodiment, the forefoot support portion 3 and / or the heel support portion 4 are provided as a ring plate, and the cross-section of the ring plate is ring-shaped. There are three possible scenarios for this:
[0054] The first type, such as Figure 3 As shown, the forefoot support part 3 is a ring plate, while the heel support part 4 is an arc plate.
[0055] The second type, such as Figure 4 As shown, the heel support part 4 is a ring plate, while the forefoot support part 3 is an arc plate.
[0056] The third type, such as Figure 2 As shown, both the forefoot support part 3 and the heel support part 4 are ring plates.
[0057] In other embodiments, the forefoot support portion 3 and / or the heel support portion 4 may be configured as an inverted U-shaped plate, with the opening of the inverted U-shaped plate positioned close to or far from the middle portion 2. There are eight possible configurations for this:
[0058] The first type, such as Figure 5 As shown, the forefoot support part 3 is an inverted U-shaped plate with the opening of the inverted U-shaped plate located near the middle part 2, while the heel support part 4 is an arc-shaped plate.
[0059] The second type, such as Figure 6 As shown, the forefoot support part 3 is an inverted U-shaped plate with the opening of the inverted U-shaped plate located away from the middle part 2, while the heel support part 4 is an arc-shaped plate.
[0060] The third type, such as Figure 7 As shown, the heel support part 4 is an inverted U-shaped plate with the opening of the inverted U-shaped plate located near the middle part 2, while the forefoot support part 3 is an arc-shaped plate.
[0061] The fourth type, such as Figure 8 As shown, the heel support 4 is an inverted U-shaped plate with the opening of the inverted U-shaped plate located away from the middle part 2, while the forefoot support 3 is an arc-shaped plate.
[0062] The fifth type, such as Figure 9 As shown, both the forefoot support part 3 and the heel support part 4 are set with inverted U-shaped plates, and the openings of the inverted U-shaped plates are located close to the middle part 2.
[0063] The sixth type, such as Figure 10 As shown, both the forefoot support part 3 and the heel support part 4 are set with inverted U-shaped plates, and the openings of the inverted U-shaped plates are set away from the middle part 2.
[0064] The seventh type, such as Figure 11 As shown, both the forefoot support part 3 and the heel support part 4 are set as inverted U-shaped plates. The opening of the forefoot support part 3 is set away from the middle part 2, while the opening of the heel support part 4 is set close to the middle part 2.
[0065] The eighth type, such as Figure 12 As shown, both the forefoot support part 3 and the heel support part 4 are set as inverted U-shaped plates. The opening of the forefoot support part 3 is set close to the middle part 2, while the opening of the heel support part 4 is set away from the middle part 2.
[0066] Combining the inverted U-shaped plate and the ring plate will result in the following four situations:
[0067] The first type has a forefoot support part 3 with a ring plate, while the heel support part 4 has an inverted U-shaped plate with the opening of the inverted U-shaped plate located near the middle part 2.
[0068] The second type has a forefoot support part 3 with a ring plate, while the heel support part 4 has an inverted U-shaped plate with the opening of the inverted U-shaped plate facing away from the middle part 2.
[0069] The third type has a ring plate for the heel support part 4 and an inverted U-shaped plate for the forefoot support part 3, with the opening of the inverted U-shaped plate located near the middle part 2.
[0070] The fourth type is a ring plate for the heel support part 4, while the forefoot support part 3 is an inverted U-shaped plate with the opening of the inverted U-shaped plate facing away from the middle part 2.
[0071] The implementation principle of a bending support component in this application embodiment is as follows: the middle part 2, the forefoot part, and the heel support part 4 are continuously bent and 3D printed, corresponding to the foot, which can well fit the contour of the foot and is more in line with ergonomic principles. This can not only effectively distribute the pressure on the foot and reduce excessive local pressure, but also enhance the support for the arch, forefoot, and heel, improving the stability and comfort of the wearer when walking or exercising.
[0072] This application also discloses a shoe sole having the bending support member, referring to... Figure 13 , Figure 14The shoe includes a sole body 5 and a bending support member built into the sole body 5. A through groove is formed through the side wall of the sole body 5. The through groove includes a first through groove 51 corresponding to the forefoot support part 3 and a second through groove 52 corresponding to the heel support part 4, to accommodate the deformation of the bending support member and reduce the weight of the sole body 5 itself. In this embodiment, specifically... Figure 2 The bending support shown is illustrated here. It should be noted that the bending support can be any of the bending support types mentioned above, depending on the specific requirements.
[0073] Example 2:
[0074] Reference Figure 15 The difference from Embodiment 1 is that the cross-section of the middle part 2 along its width direction is wavy.
[0075] Example 3:
[0076] Reference Figure 16 , Figure 17 The difference from Embodiment 1 is that the upper and / or lower surfaces of the middle portion 2 are provided with longitudinal reinforcing ribs 22. Furthermore, the longitudinal reinforcing ribs 22 can be extended to the forefoot support portion 3 and / or the heel support portion 4 as needed.
[0077] 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.
