Description

Technical Field

[0001] This utility model belongs to the field of footwear technology, and in particular relates to a sneaker. Background Technology

[0002] With the rise of golf in China, the sports accessories market has begun to flourish. Golf shoes are shoes specifically designed for golf. For example, a golf shoe disclosed in patent application number CN202322564257.7 includes a wearable shoe body and a ball marker. The shoe has a recessed portion on the outer side wall of the middle section, and a ball marker connecting device is fixed inside the recessed portion. After the ball marker is embedded in the recessed portion, the ball marker connecting device is fixedly connected to the ball marker. The ball marker can be separated and removed from the ball marker connecting device in the recessed portion.

[0003] The existing golf shoes cannot effectively help prevent the lower limbs (especially the knees) from shifting laterally during the swing, resulting in low power transfer efficiency and loss of directional control. The shoes provide poor assistance to the movement, so it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a shoe that effectively improves the auxiliary effect of the shoe on golf.

[0005] In view of this, the present invention provides a sneaker, comprising:

[0006] The sole has an upper on it;

[0007] The sole also includes:

[0008] The midsole consists of a forefoot portion and a heel portion, and has a central seam extending along the length of the foot.

[0009] Outsole, which is arranged on the bottom surface of the midsole, and a through-outsole is arranged on the outsole corresponding to the center seam;

[0010] The self-reinforcing plastic pad is arranged on the top surface of the midsole. The self-reinforcing plastic pad is flat and covers three areas of the foot: the big toe ball, the little toe ball, and the heel directly below the foot joint.

[0011] The outsole has two inner and outer edges centered on the gap. When the outsole is compressed, the inner edge sinks more than the outer edge to naturally generate an outward anti-tilting support force.

[0012] In this technical solution, when a player performs a swing, their center of gravity gradually shifts from a uniform distribution during the stance phase to the target side (e.g., the left side for a right-handed player). At this time, the outsole experiences vertical pressure from the foot. Due to the through-type structure between the center seam and the outsole gap, the support stiffness of the inner edge of the outsole (the side closer to the gap) is lower than that of the outer edge. According to the beam bending theory in mechanics of materials, under the same load, the inner edge with lower stiffness will produce a greater amount of sinking, while the outer edge will sink relatively less, creating a height difference. This height difference causes the outsole to have a slight tilt around the gap axis, thereby generating an upward reaction force on the outer edge. The horizontal component of this reaction force is the anti-roll support force, which points outward. This effectively suppresses the tendency of the knee to move inward, effectively ensuring the efficiency of power transmission, avoiding loss of directional control, and improving the shoe's auxiliary effect on golf. At the same time, the self-reinforcing plastic pad has lightweight, high rebound auxiliary effect, and impact and bending resistance characteristics. Furthermore, the pad covers three areas: the big toe, the little toe, and the heel, corresponding to the main force points of the foot during the swing. When the player transfers weight, it can effectively guide pressure in the forefoot and provide stable support in the heel. Through dynamic deformation, it can generate reversible deformation under pressure, absorb and store energy, and release it during the power phase of the swing, thereby further improving the shoe's auxiliary effect on golf.

[0013] Furthermore, the above technical solution also includes:

[0014] Anti-slip studs are integrally formed and arranged on the bottom surface of the outsole.

[0015] In the above technical solution, the anti-slip studs further include:

[0016] The nail body includes a ring portion and a pressure-bearing portion disposed at the center of the ring portion;

[0017] Several hooks are evenly spaced along the circumference of the nail body at the edge of the nail body;

[0018] The pressure-bearing part can be compressed under pressure and drive the hook body to retract synchronously.

[0019] In the above technical solution, furthermore, the front edge line of the self-reinforcing plastic pad coincides with the inclined line at the base of the toes.

[0020] In the above technical solution, the pressure-bearing part of the nail body is further provided with star-shaped ribs. When the star-shaped ribs are compressed, they deform toward the sole of the shoe and automatically return to their normal position after the pressure is removed.

[0021] In the above technical solution, further, the outsole is provided with a plurality of elliptical through holes that extend through the outsole along the width of the foot. The outer thickness of the elliptical through holes is greater than the inner thickness to increase the support elasticity of the outer edge of the outsole.

[0022] The beneficial effects of this utility model are:

[0023] 1. Through the coordinated design of the midsole seam and outsole gap, the shoe can actively generate anti-lateral support during the swing, effectively suppressing the tendency of the knee to move inward, effectively ensuring the efficiency of power transmission, avoiding loss of directional control, and improving the shoe's auxiliary effect on golf.

[0024] 2. Through the self-reinforcing plastic pad and overall structural design, the shoe can effectively guide pressure in the forefoot and provide stable support in the heel when the player transfers weight. Through dynamic deformation, it can generate reversible deformation under pressure, absorb and store energy, and release it during the swing, thereby further improving the shoe's auxiliary effect on golf.

[0025] 3. The anti-slip stud design enables the shoes to effectively cope with both soft and hard surfaces, achieving adaptive adjustment to different playing surfaces and improving the shoes' grip. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] Example 1:

[0037] This application provides a sneaker, including: a sole 1, on which an upper is disposed;

[0038] The sole 1 also includes: a midsole 2, which is composed of a forefoot portion 20 and a heel portion 21, and has a central seam 3 extending along the length of the foot; an outsole 4, which is located on the bottom surface of the midsole 2, and has a through-hole 40 corresponding to the central seam 3; and a self-reinforcing plastic pad 5, which is located on the top surface of the midsole 2, and is flat and covers three areas of the foot: the big toe ball, the little toe ball, and the heel directly below the foot joint.

[0039] Among them, the outsole 4 forms two inner and outer edges with the gap 40 as the center. When the outsole 4 is compressed, the inner edge sinks more than the outer edge to naturally generate an anti-tilting support force to the outside.

[0040] The front edge of the self-reinforcing plastic pad 5 coincides with the inclined line at the base of the toes.

[0041] Furthermore, the midsole 2 is made of EVA (ethylene-vinyl acetate copolymer) material and is manufactured by injection molding. The width of the midsole 3 is between 1.5-3mm, starting from the toe root position of the forefoot 20 at the front end and extending to the corresponding area of ​​the ankle joint of the heel 21 at the rear end. The outsole 4 is made of TPU (Shore A hardness 85A) material. The outsole 4 and the midsole 2 are fixedly connected by hot melt adhesive or stitching. The gap 40 is aligned with the midsole 3 in the vertical direction, forming a through structure extending from the top surface of the sole 1 to the bottom surface. The self-reinforcing plastic pad 5 is fixed to the top surface of the midsole 2 by adhesive. The front edge of the pad coincides with the inclined line of the toe root. This inclined line is the line connecting the head of the fifth metatarsal to the root of the big toe, with an inclination angle of approximately 15°-25°.

[0042] In this embodiment, when a player performs a swing, their center of gravity gradually shifts from a uniform distribution during the stance phase to the target side (e.g., the left side for a right-handed player). At this time, the outsole 4 experiences vertical pressure from the foot. Due to the through structure between the center seam 3 and the gap 40 of the outsole 4, the support stiffness of the inner edge (the side closer to the gap 40) of the outsole 4 is lower than that of the outer edge. According to the beam bending theory in mechanics of materials, under the same load, the inner edge with lower stiffness will produce a greater amount of sinking, while the outer edge will sink relatively less, creating a height difference. This height difference causes the outsole 4 to produce a slight tilt angle around the axis of the gap 40, thereby generating an upward reaction force on the outer edge. The horizontal component of this reaction force is the anti-roll support force, which points outward. This effectively suppresses the tendency of the knee to move inward, effectively ensuring the efficiency of the power transmission of the shot, avoiding loss of directional control, and improving the auxiliary effect of the shoe on golf. At the same time, the self-reinforcing plastic pad 5 has the characteristics of being lightweight, having a high rebound auxiliary effect, and being impact-resistant and bend-resistant. Furthermore, the pad covers three areas: the big toe, the little toe, and the heel, corresponding to the main force points of the foot during the swing. When the player transfers weight, it can effectively guide pressure in the forefoot and provide stable support in the heel. Through dynamic deformation, it can generate reversible deformation under pressure, absorb and store energy, and release it during the power phase of the swing, thereby further improving the shoe's auxiliary effect on golf.

[0043] Example 2:

[0044] This embodiment provides a sneaker that, in addition to the technical solutions of the above embodiments, also has the following technical features, including: anti-slip studs 6, which are integrally formed and arranged on the bottom surface of the outsole 4.

[0045] The anti-slip stud 6 also includes: a stud body 60, the stud body 60 including a ring portion 61 and a pressure-bearing portion 62 disposed at the center of the ring portion 61; and a plurality of hooks 63, the plurality of hooks 63 being evenly spaced along the circumference of the stud body 60 at the edge of the stud body 60.

[0046] Among them, the pressure-bearing part 62 can be compressed under pressure and drive the hook body 63 to retract synchronously.

[0047] The pressure-bearing part 62 of the nail body 60 is provided with star-shaped ribs 64. When the star-shaped ribs 64 are compressed, they deform toward the sole 1 and automatically return to their normal position after the pressure is removed.

[0048] Furthermore, the ring 61 is fixed to the bottom surface of the outsole 4, and the pressure-bearing part 62 is connected to the inner edge of the ring 61, allowing it to contract towards the sole 1 under vertical pressure. The pressure-bearing part 62 is equipped with star-shaped ribs 64, which radiate outward from the center. Each rib 64 has a width of 1.2-2 mm and a height of 0.8-1.5 mm, and the number of hooks 63 can be 8-12. The hooks 63 are curved, with the outer edge higher than the inner edge. When the pressure-bearing part 62 contracts, the deformation of the ring 61 drives the hooks 63 to retract synchronously. Conversely, when the pressure is removed, the pressure-bearing part 62 automatically resets, and the hooks 63 return to their original open state.

[0049] In this embodiment, when facing a soft surface, when the pressure-bearing part 62 of the spike 60 contacts a small stone or a harder base, the vertical load forces the pressure-bearing part 62 to contract towards the sole 1. The star-shaped ribs 64 elastically buckle, and their radius of curvature decreases as the pressure increases. This causes the ring part 61 to deform and be pulled, generating centripetal displacement, which in turn drives the hook 63 to retract synchronously. At this time, the tip of the hook 63 retracts inward, increasing the contact area with the ground and avoiding excessive cutting. At the same time, the friction generated by the inward retraction provides sufficient grip. When the pressure-bearing part 62 is not under significant pressure (such as on a flat and soft surface like a lawn), the pressure-bearing part 62 is in its normal position, and the hook 63 returns to its original open state. At this time, the tip of the hook 63 extends outward, providing moderate grip with a smaller contact area. This ensures stable positioning and avoids damage to the lawn. Compared with the prior art, this invention enables the shoe to effectively cope with both soft and hard surfaces, achieving adaptive adjustment for different surfaces and improving the shoe's grip performance.

[0050] Example 3:

[0051] This embodiment provides a shoe that, in addition to the technical solutions of the above embodiments, also has the following technical features: the outsole 4 is provided with a plurality of elliptical through holes 41 that penetrate the outsole 4 along the width direction of the foot, and the outer thickness of the elliptical through holes 41 is greater than the inner thickness to increase the support elasticity of the outer edge of the outsole 4.

[0052] Furthermore, the major axis of the ellipse runs along the front-to-back direction, while the minor axis runs along the left-to-right direction. The outer thickness of the ellipse through-hole 41 (the side closer to the outer edge of the outsole 4) is greater than the inner thickness (the side closer to the slot 40), with a thickness difference of 0.5-1.2 mm. This design is used to increase the support elasticity of the outer edge of the outsole 4, allowing the outer edge to produce more significant elastic deformation under pressure, further strengthening the outward support force.

[0053] In this embodiment, the outer thickness is greater than the inner thickness, making the moment of inertia of the outer edge of the outsole 4 greater than that of the inner edge. According to the bending stiffness formula, the outer edge has greater bending stiffness and smaller deformation under the same pressure, thereby further aggravating the difference in sinking between the inner and outer edges and enhancing the anti-roll support force. The major axis of the ellipse is along the front-back direction, and the minor axis is along the left-right direction. This shape design gives the outsole 4 high stiffness in the front-back direction (swing direction) to ensure the transmission of propulsive force during the swing, while it has moderate elasticity in the left-right direction (lateral movement direction) to facilitate the generation of the required support moment.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
