Description

Technical Field

[0001] This invention relates to the field of athletic footwear, specifically to a shoe spike, an athletic footwear sole, and an athletic footwear. Background Technology

[0002] In speed-based competitive events, such as various sprint events in track and field, athletes need their shoes to provide more grip during acceleration on tracks like synthetic tracks and ice rinks. This is crucial for maintaining balance and accelerating. Better grip enhances stability and acceleration, improving performance. Therefore, athletes typically wear spiked shoes in these events. However, current athletic shoe spikes generally consist of a single, integrated spike body and tip. The tip penetrates the track to provide some grip. But because the tip is a continuous, smooth conical surface, the friction provided during its displacement after penetration is insufficient, resulting in inadequate grip for the athlete. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a shoe spike, a sports shoe sole, and a sports shoe that can provide stronger grip for sports.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] A shoe nail includes a nail body, a nail tip, and at least one spike, all integrally formed, the nail tip being located at one end of the nail body, the outer surface of which is conical, and the spike extending from the conical surface in a direction away from the nail body.

[0006] Furthermore, the spike is a rotated body, and the rotation center line of the spike intersects with the rotation center line of the conical surface.

[0007] Furthermore, the angle between the rotation center line of the spike and the rotation center line of the conical surface is less than or equal to 30 degrees.

[0008] Furthermore, each of the spikes is close to each other at its root located at the spike tip.

[0009] Furthermore, the number of spikes is three.

[0010] Furthermore, the shoe nail also includes a heel plate located at the other end of the nail body and protruding radially from the nail body.

[0011] An athletic shoe sole includes a sole body and a plurality of spikes as described above, wherein the spikes are mounted on the forefoot portion of the sole body, the heel plate of the spikes is embedded in the sole body, and the spike tips protrude from the sole body.

[0012] Furthermore, the sole body has several protrusions formed on its forefoot, and each protrusion is embedded with several shoe spikes.

[0013] Furthermore, each of the aforementioned protrusions is divided into several protrusion groups arranged along the front-back direction, each protrusion group including at least one protrusion, and if the protrusion group includes two or more protrusions, each protrusion in the protrusion group is arranged along the left-right direction; all the cleats on each protrusion are divided into two or more cleat groups arranged along the front-back direction, and each cleat in each cleat group is arranged along the left-right direction; at least two cleats in adjacent cleat groups on at least one protrusion do not overlap in projection onto a first plane parallel to the extension direction of the protrusion and perpendicular to the ground.

[0014] An athletic shoe includes an upper and an athletic shoe sole as described above, the upper being fixed to a surface of the athletic shoe sole opposite to the direction of extension of the spikes.

[0015] Compared with existing technologies, the above solution has the following beneficial effects:

[0016] In this invention, the spikes on the cleats increase the contact area with the ground, thereby improving grip and meeting the stability and acceleration requirements of athletes on the track, thus improving race performance. Dynamic analysis experiments using the explicit analysis solver software Abaqus Explicit demonstrate that cleats with the spike structure described in this application have stronger grip than cleats without the spike structure.

[0017] The spike is a spiral-shaped body, which facilitates the spike's penetration into the track. The center line of rotation of the spike intersects with the center line of rotation of the conical surface, making it less likely for the spike and spike tip to be damaged by torque.

[0018] The angle between the rotation center line of the spike and the rotation center line of the cone surface is less than or equal to 30 degrees, which helps the spike penetrate the track and improves grip.

[0019] The spikes are placed close to each other at their bases, which increases the contact area with the ground and enhances their strength, thus preventing damage to the spikes.

[0020] The number of spikes is three, which increases the contact area with the ground and allows the spikes to be arranged close to each other at their base, thus improving grip and spike strength.

[0021] The heel plate on the shoe nails makes it easier for the nails to be firmly installed on the sole of the shoe.

[0022] The aforementioned spikes are installed in the forefoot of the shoe sole to better enhance the grip of the spikes during running.

[0023] The forefoot of the sole has a protrusion to facilitate the installation of cleats and enhance the strength of the sole.

[0024] The arrangement of the protrusions along the front-to-back direction facilitates the bending of the forefoot in the front-to-back direction, which is beneficial for athletes to generate power from the sole of their feet. The projections of any two studs in two adjacent stud groups on a first plane that is parallel to the extension direction of the protrusion and perpendicular to the ground do not overlap, so that the studs form an interlaced layout, which is beneficial to improving grip.

[0025] Sports shoes equipped with the sole of the sports shoe of the present invention have good grip, improve the stability and acceleration characteristics of sports, and improve the performance of the competition. Attached Figure Description

[0040] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0041] The athletic shoe 1000 in this embodiment is particularly suitable for skeleton racing, providing athletes with excellent grip on ice tracks. Figure 1 As shown, the athletic shoe 1000 includes an athletic shoe sole 100 and an upper 200, wherein the athletic shoe sole 100 includes a plurality of spikes 1 and a sole body 2, and the upper 200 is fixed to the surface of the athletic shoe sole 100 away from the extending direction of the spikes 1.

[0042] Among them, such as Figure 2 , Figure 3 , Figure 4The spike 1 in this embodiment includes a heel plate 14, a spike body 13, a spike tip 12, and three spikes 11 integrally formed. The heel plate 14 is located at one end of the spike body 13 and protrudes radially from the spike body 13. The spike tip 12 is located at the other end of the spike body 13, and its outer surface is conical. The spikes 11 extend from the conical surface 121 of the spike tip 12 in a direction away from the spike body 13. The three spikes 11 are close to each other at their roots on the conical surface 121. Each spike 11 is a cylinder, and the rotation center line of the spike 11 intersects the rotation center line of the conical surface 121 to form an angle A equal to 30 degrees. In other embodiments, this angle A may be less than 30 degrees. In this embodiment, the spike has three spikes 11, which can increase the contact area with the ground, thereby improving grip and meeting the stability and acceleration requirements of athletes on the track, thus improving competition performance. The spike 11 is a spirally formed body, which facilitates its penetration into the track. The rotation center line of the spike intersects with the rotation center line of the conical surface, reducing the likelihood of torque damage to the spike 11 and spike tip 12. The angle between the rotation center line of the spike 11 and the rotation center line of the conical surface 121 is 30 degrees. Of course, in other embodiments, this angle can be less than 30 degrees, which facilitates the spike 11's penetration into the track and improves grip. The spikes 11 are close to each other at their roots at the spike tip 12, which increases the contact area with the ground and enhances the strength of the spikes 11, preventing damage. There are three spikes 11, which increases the contact area with the ground and allows the spikes to be arranged close to each other at their roots, thus improving grip and spike strength.

[0043] like Figure 5As shown, in the sports shoe sole 100, the sole body 2 has several protrusions 21 formed on its forefoot. Each protrusion 21 is embedded with several cleats 1. The heel plate 14 is embedded in the protrusion 21, which facilitates the firm installation of the cleats 1 on the sole body 2. The cleat tips 12 protrude from the protrusion 21. Each protrusion 21 is divided into several protrusion groups arranged in the front-back direction. Each protrusion group includes at least one protrusion 21. If a protrusion group includes two or more protrusions 21, the protrusions 21 in the protrusion group are arranged in the left-right direction. In this embodiment, there are seven protrusion groups, which are, from back to front, the first protrusion group 21a, the second protrusion group 21b, the third protrusion group 21c, the fourth protrusion group 21d, the fifth protrusion group 21e, the sixth protrusion group 21f, and the seventh protrusion group 21g. In this embodiment, the first boss group 21a and the fourth boss group 21d each have two bosses 21, both arranged in the left-right direction, while the remaining boss groups each have only one boss 21. All the studs 1 on each boss 21 are divided into two or more stud groups arranged in the front-back direction. In this embodiment, except for the boss 21 of the seventh boss group 21g which has three stud groups arranged in the front-back direction, the remaining bosses 21 each have only two stud groups. Each stud 1 in each stud group is arranged in the left-right direction. At least two studs 1 in any two adjacent stud groups on at least one boss 21 will not have their projections coincide on a first plane 3 parallel to the extension direction of the boss 21 and perpendicular to the ground. In this embodiment, in the two stud groups of the boss 21 of the third boss group 21c, the projections of all studs 1 on the first plane 3 do not coincide. As shown in the figure, the projection 1a' of the first stud 1a on the first plane 3 and the projection 1b' of the second stud 1b on the first plane 3 do not coincide, and the same applies to any other two studs 1. The forefoot of the sole body 2 has a protrusion 21, which facilitates the installation of the spikes 1 and enhances the strength of the sole. The arrangement of the protrusion 21 along the front-to-back direction facilitates the bending of the forefoot in the front-to-back direction, which is beneficial for the athlete to exert force with the sole of the foot. The projections of any two spikes 1 in two adjacent spike groups on the first plane 3, which is parallel to the extension direction of the protrusion and perpendicular to the ground, do not coincide, so that the spikes 1 form an interlaced layout, which is beneficial to improving grip.

[0044] In the above implementation, the explicit analysis solver software Abaqus Explicit is used for dynamic analysis to simulate the motion of the spikes passing through ice and predict the force response. The simulation method involves constructing four comparison groups, each consisting of two rows of ten spikes. The first comparison group consists of two rows of aligned, un-spikeed ordinary spikes; the second comparison group consists of two rows of aligned spikes (as described in this embodiment); the third comparison group consists of two rows of staggered, un-spikeed ordinary spikes; and the fourth comparison group consists of two rows of staggered, un-spikeed spikes (as described in this embodiment). The spikes in each comparison group are located at the same position above the ice material. The spikes are modeled as rigid bodies, and all spikes in each comparison group move synchronously rather than individually. The ice layer is modeled as a deformable solid block, with its bottom and sidewalls constrained to prevent movement and allow the spikes to penetrate the ice. The simulation process consists of two steps: in step one, the spikes in each comparison group are vertically displaced by 4 mm within the ice layer; in step two, the spikes are horizontally displaced by 3.5 mm after passing through the ice layer. The predicted force required to drag the spikes horizontally indicates the traction force of the spike configuration. The resistance of each configuration is compared to determine which configuration will provide the greatest traction. Data measured in the simulation experiment are as follows: Figure 6 The x-axis represents horizontal displacement in mm, and the y-axis represents traction force in N. L1 is the second comparison group, L2 is the fourth comparison group, L3 is the third comparison group, and L4 is the first comparison group.

[0045] The simulation results above show that the grip of the spikes in this embodiment is significantly better than that of ordinary spikes without spikes. Furthermore, within a horizontal displacement of 3 mm, the grip of staggered spikes is better than that of aligned spikes.

[0046] The sports shoe sole 100 and sports shoe 1000 with spikes 1 in this embodiment can be used not only in skeleton racing, but also in other sports that require spikes 1 for grip, such as running spikes. Sports shoes equipped with the sports shoe sole of this application have good grip, improve the stability and acceleration characteristics of the movement, and improve competition performance.

[0047] In other embodiments, the spike comprises a single unit consisting of a spike body, a spike tip, and a spike. The spike tip is located at one end of the spike body, and its outer surface is conical. The spike extends from the conical surface of the spike tip in a direction away from the spike body. The spike at the spike tip increases the contact area with the ground after the spike penetrates the track, providing greater grip. Preferably, the spike is a spun body, with its rotation center line intersecting the rotation center line of the conical surface of the spike tip. This facilitates the spike's penetration into the track, and the forces acting on the spike and the spike tip during penetration are less likely to create torsional damage. Further, the rotation center line of the spike intersects the rotation center line of the conical surface of the spike tip at a 30-degree angle. Of course, in other embodiments, the angle between the rotation center line of the spike and the rotation center line of the conical surface of the spike tip is less than 30 degrees, thus facilitating both spike penetration into the track and providing good grip.

[0048] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
