Description

Technical Field

[0001] The present invention relates to the technical field of footwear, and more particularly to an elastic plate for shoes. Background Art

[0002] Sports shoes can be divided into three categories according to the needs of biomechanics: providing shock absorption, providing stability, and providing motion control. In order to improve the shock absorption and stability of sports shoes on the market, shock-absorbing elastic plates are usually set in the soles to assist the foot to be evenly stressed during exercise and help the foot to absorb shock. However, different people have different needs for sports shoes, and the existing shock-absorbing elastic plates of existing sports shoes have poor shock absorption effect when the wearer is running, and the propulsion effect provided to the foot when the foot is lifted is weak.

[0003] In view of this, the present applicant conducted in-depth research on this basis, which led to the emergence of this case. Summary of the invention

[0004] The purpose of the present invention is to provide an elastic plate for shoes with good shock absorption effect, which can provide propulsion force to the foot when the foot is lifted, making the movement easier and more comfortable.

[0005] To achieve the above object, the solution of the present invention is: A shoe elastic plate comprises a main body, wherein the main body comprises an elastic plate body and two elastic wings arranged opposite to each other, wherein the two elastic wings are both strip-shaped structures, the two elastic wings are respectively arranged on the sides of the elastic plate body, the first ends of the two elastic wings are respectively arranged at the arch positions of the elastic plate body, and the two elastic wings are both arranged to bend upward along the rear side.

[0006] Portions of the two elastic wings adjacent to their respective first ends are twisted inwardly or outwardly.

[0007] The elastic plate body is provided with a propulsion portion corresponding to the mid-waist position and the heel position, and the propulsion portion includes a first section, a second section and a second section that are integrally connected, the first section is arranged to be gradually bent upward along the rear side, the second section is arranged to be inclined upward along the rear side, and the third section is arranged to be gradually bent upward toward the rear side relative to the second section, wherein the first section smoothly transitions with the mid-waist position of the elastic plate body, the second section smoothly transitions with the arch position of the elastic plate body, and the second section smoothly transitions with the third section.

[0008] The pushing portion is in the shape of a spoon.

[0009] The forefoot position of the elastic plate body is arranged as an arc-shaped portion that tilts upward, and the forefoot position of the elastic plate body smoothly transitions to the middle waist position of the elastic plate body.

[0010] The main body is made of plastic material.

[0011] The main body is a TPU plate or a nylon plate.

[0012] A wave portion is provided at the forefoot position of the elastic plate body, and the wave portion includes at least one wave portion, each of which extends along the width direction of the elastic plate body; when there are multiple wave portions, each of the wave portions is arranged in sequence along the length direction of the elastic plate body.

[0013] Each of the wave portions is in an arc shape convex upward.

[0014] The elastic plate body is provided with a hollow portion at the rear side corresponding to the wave portion, and the hollow portion includes at least one hollow part, and each of the hollow parts is arranged along the width direction of the elastic plate body.

[0015] After adopting the above structure, the present invention has the following beneficial effects: 1. The present invention adopts a combination of an elastic plate and two elastic wings, and the two elastic wings correspond to the heel position of the foot. Due to the structural setting of the two elastic wings and the elasticity of the two elastic wings, the two elastic wings have sufficient elastic space, and the two elastic wings are strip-shaped, so that the areas corresponding to the feet of the two elastic wings are larger. Therefore, when the two elastic wings are respectively subjected to pressure, the two elastic wings undergo elastic deformation, which effectively improves the shock absorption effect and stability of the shoes. When the foot is lifted, the two elastic wings rebound, pushing the heel position of the foot to move upward, giving the heel a driving force, thereby improving the shock absorption effect and the support effect, and at the same time providing a driving force to the foot during exercise, making the wearer exercise more easily and comfortably.

[0016] 2. The present invention adopts a twisting setting of the corresponding parts of the two elastic wings, and the first ends of the two elastic wings are supported as fulcrums. The area of ​​the force-bearing positions of the two elastic wings is large, which can greatly improve the strength of the two elastic wings, avoid damage to the two elastic wings, and ensure the service life of the main body.

[0017] 3. The present invention adopts the setting of the propulsion part, which is in the shape of a spoon. When the wearer's heel applies pressure to the propulsion part, it can provide support and buffer space for the wearer's foot. Then, when the wearer lifts his foot, the propulsion part rebounds, further providing propulsion force to the wearer, making it easier for the wearer to run. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0024] An elastic plate for shoes is suitable for the soles commonly found on the market and is installed in the soles according to conventional operations in the footwear industry, for example, Figure 4 As shown, the elastic plate for shoes is an embedded plate of the sole, and the sole and the upper form a shoe; it should be noted that the above example is only used as an example, and the elastic plate for shoes can also be installed in other ways.

[0025] For the convenience of description, the orientation of the present invention when it is normally embedded in the sole is taken as the reference direction of the present invention.

[0026] like Figure 1-3 As shown, the elastic plate for shoes includes a main body 100, which includes an elastic plate body 1 and a shock-absorbing structure. The elastic plate body 1 is compatible with a conventional sole. In this embodiment, for the convenience of description, the forefoot position of the elastic plate body 1 is the front side, the opposite side is the rear side, the horizontal direction perpendicular to the front and back is the left and right direction, and the range surrounded by the elastic plate body 1 is the inner side, and the opposite side is the outer side; the above-mentioned shock-absorbing structure includes two elastic wings 2, the two elastic wings 2 are respectively arranged on the left and right sides of the elastic plate body 1, the two elastic wings 2 are arranged opposite to each other, the two elastic wings 2 are both in a strip shape, the first ends of the two elastic wings 2 are respectively fixedly connected to the arch position of the elastic plate body 1, and the two elastic wings 2 are both bent upward along the rear side so that the two elastic wings 2 have sufficient elastic space respectively.

[0027] Furthermore, the above-mentioned main body 100 is made of elastic plastic material. For example, the elastic plate body of the main body 100 is made of TPU plate or nylon plate commonly used in the footwear industry. Correspondingly, the two elastic wings 2 are made of TPU or nylon. In this embodiment, the elastic plate body is taken as TPU plate for example.

[0028] Furthermore, the first ends of one side of the two elastic wings 2 are respectively fixedly connected to the side of the elastic plate body 1. Specifically, the first end of one side of the elastic wing 2 located on the left side is fixedly connected to the left side of the bottom surface of the elastic plate body 1, and the first end of one side of the elastic wing 2 located on the right side is fixedly connected to the right side of the bottom surface of the elastic plate body 1; wherein, the first ends of the two elastic wings 2 are respectively connected to the elastic plate body 1 in a conventional manner, for example, the two elastic wings 2 are respectively connected to the side of the elastic plate body 1 in an integral manner, bonded or hot-melted, etc., and the connection method is conventionally selected according to the material of the elastic plate body 1. Preferably, the first ends of the two elastic wings 2 are respectively arranged at the arch position of the elastic plate body 1, and the best two elastic wings 2 are respectively arranged at the mid-waist position of the elastic plate body 1, so as to provide shock-absorbing protection for the wearer's foot from the arch position to the heel position.

[0029] Furthermore, the two elastic wings 2 mentioned above have the same structure, so one of them is taken as an example for explanation. The part of the elastic wing 2 adjacent to the first end is arranged to be twisted upward and inward, and the two elastic wings 2 correspond to the foot range of the wearer respectively; in this way, when the elastic wing 2 is subjected to force, the elastic wing 2 is elastically deformed with its first end as the fulcrum. Since the corresponding part of the elastic wing 2 is twisted, the force-bearing area of ​​the elastic wing 2 is larger, and the physical rigidity of the elastic wing 2, that is, the strength of the elastic wing 2, is improved, so that the elastic wing 2 is not easily damaged. Preferably, the part of the elastic wing 2 adjacent to the first end can also be arranged upward and twisted outward, and this part is called the twisting part 21, that is, taking the elastic wing 2 on the left side as an example, the part of the elastic wing 2 adjacent to the first end is arranged upward, twisted to the left side, and extended backward, so that the elastic wing 2 is located on the left side of the elastic plate body 1, which can correspond to the foot of the wearer.

[0030] As a preferred embodiment, the elastic plate body 1 is provided with a propulsion portion 3 between the middle waist position and the heel position, and the propulsion portion 3 includes a first section, a second section and a third section which are connected in sequence from front to back, the first section 31 of the propulsion portion is gradually bent upward along the rear side, the second section 32 of the propulsion portion 3 is arranged tilted upward along the rear side, and the third section 33 of the propulsion portion 3 is gradually bent upward along the rear side relative to the second section 32, wherein the first section 31 of the propulsion portion 3 smoothly transitions with the middle waist position of the elastic plate body 1, and the first section 31 of the propulsion portion 3 smoothly transitions with the second section 32 of the propulsion portion 3. The second section 33 of the propulsion part 3 smoothly transitions with the third section 33 of the propulsion part 3, so that the propulsion part 3 forms a spoon shape; in this way, when the wearer's foot applies pressure to the elastic plate body 1, since the elastic plate body 1 has a buffer space, the wearer's foot has enough space for buffering when it moves downward, thereby improving the shock-absorbing effect of the foot; when the wearer's foot is lifted, due to the return of the propulsion part 3 of the elastic plate body 1, the propulsion part 3 rebounds upward, thereby giving the foot an upward propulsion force when the wearer lifts his foot, making it easier for the wearer to lift his foot, thereby making exercise easier and more comfortable.

[0031] Furthermore, the forefoot position of the elastic plate body 1 is arranged according to the structure of a conventional inner plate (such as a carbon plate). For example, the forefoot position of the elastic plate body 1 can be arranged as an upwardly raised arc portion, and the arc portion smoothly transitions with the mid-waist position of the elastic plate body. It should be noted that the structure of the front side of the mid-waist position of the elastic plate body 1 here is the same as the structure of the inner plate of a conventional sole.

[0032] Furthermore, the elastic plate body 1 is also provided with a warpage adjustment structure, and the warpage adjustment is specifically described as follows.

[0033] The forefoot position of the above-mentioned elastic plate body 1 is provided with a wave portion, which includes at least one wave portion 4, each wave portion 4 extends along the width direction (i.e., the left-right direction) of the elastic plate body 1, and the two end portions of each wave portion 4 extend to the left side and the right side of the elastic plate body 1 respectively; preferably, there are multiple wave portions 4, each wave portion 4 is an arc shape convex upward, and each wave portion 4 is arranged in sequence along the length direction (i.e., the front-to-back direction) of the elastic plate body 1, and each wave portion 4 is connected in sequence from front to back, that is, each wave portion 4 in the wave portion forms a continuous wave shape together, so that the forefoot portion of the elastic plate body 1 is formed with a continuous bendable portion, which is convenient for the subsequent adjustment of the warping of the forefoot position of the elastic plate body 1.

[0034] As a preferred embodiment, the elastic plate body 1 is provided with a hollow portion on the rear side corresponding to the wave portion, and the hollow portion includes at least one hollow portion 5, each hollow portion 5 is arranged along the left and right direction of the elastic plate body 1 (i.e., the width direction of the elastic plate body 1) to improve the bending effect when adjusting the forefoot position of the elastic plate body 1; preferably, there are multiple hollow portions 5, and in this embodiment, 5 hollow portions are taken as an example for explanation, and each hollow portion 5 is arranged in sequence along the length direction of the elastic plate body 1 (i.e., the front and rear direction), and the length of each hollow portion 5 is gradually reduced from front to back to further provide a better bending effect.

[0035] It should be noted that the front end of the elastic plate body 1 is provided with two fixing holes, and adjustment ropes are respectively fixed to the two fixing holes. One end of the two adjustment ropes are respectively connected to the rotating buckles on the conventional shoe upper, so that the front end of the elastic plate body 1 is pulled by the rotating buckle to adjust the curvature of the forefoot position of the elastic plate body 1.

[0036] In addition, the structure of the aforementioned rotating buckle is the same as the structure of the rotating buckle used on the market to adjust the tightness of shoelaces, so it will not be described in detail.

[0037] The present invention discloses an elastic plate for shoes. When a wearer wears the shoes with the sole of the present invention, during the wearer's exercise, when the wearer lands on the two elastic wings 2 and the propulsion part 3 of the elastic plate body 1 are elastically deformed respectively, and the two elastic wings 2 and the propulsion part each have sufficient buffer space to cushion and support the wearer's foot. Then, when the wearer lifts the foot, the elastic wings 2 and the propulsion part 3 return to their original positions to provide an upward propulsion force to the wearer's foot, so as to push the wearer to lift the foot more easily, thereby making the exercise easier and more comfortable.
