Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a sole pattern structure for a bicycle pedal, and a sole and a shoe containing the pattern structure. Background Art

[0002] BMX is an extreme sport known as "Bicycle Motocross," or BMX for short. Athletes are ranked based on a final score derived from three key performance criteria: course design, difficulty of movements, and individual style. The unique characteristics of freestyle BMX dictate that most technical moves are performed in the air. Takeoff technique is a key factor in determining parameters such as liftoff angle, height, duration, and displacement, and is crucial for an athlete's ability to execute difficult mid-air maneuvers like somersaults and twists. During a BMX turn, the wrist is held upright, with weight placed on the outside foot, slightly bent. This placement helps maintain balance during leaning turns and allows for a strong push from the outside foot to provide initial turning momentum, which can be crucial in a race where every second counts.

[0003] As a crucial piece of equipment in BMX cycling, footwear must possess performance features such as shock absorption, anti-slip properties, wear resistance, and stability. The most important aspect is the fit between the sole pattern and the BMX pedals. This provides stability and a sense of security during exercise, while the appropriate sole thickness provides a more comfortable pedaling feel and stronger support.

[0004] Currently, the saddle patterns of professional BMX shoes are mostly circular or hexagonal patterns that adapt to the raised pedals, and the area of ​​the raised pedals is relatively small, accounting for only 50% of the entire sole. Utility Model Content

[0005] The purpose of this utility model is to provide a sole pattern structure for BMX pedals, as well as a sole and shoe containing the pattern structure. By providing triangular and diamond-shaped groove structures, the pattern structure can better and more comprehensively fit the various shapes of studs on the pedals, allowing athletes to quickly complete the fit between the sole and the pedals. The specific technical solution is as follows:

[0006] A sole pattern structure for a BMX pedal comprises a first area and a second area. The first area is located at a portion of the sole pattern structure corresponding to the midfoot of a human body, and the portion of the sole pattern structure other than the first area is the second area. A first pattern structure having a plurality of diamond-shaped grooves is provided in the first area to engage with raised studs on the rear side of the BMX pedal. A second pattern structure having a plurality of triangular grooves is provided in the second area to engage with raised studs on the front side and in the middle of the BMX pedal.

[0007] Furthermore, the first texture structures in the first area are arranged in a triangular array.

[0008] Furthermore, six first pattern structures are provided in the first area, and the number thereof gradually decreases from the front to the back.

[0009] Furthermore, the first texture structure includes four first convex edges, the second texture structure includes three second convex edges, and the length of the first convex edges is smaller than the length of the second convex edges.

[0010] Furthermore, two second grain structures adjacent to each other in the second region have a same second convex edge, so that the two second grain structures are spliced ​​to form a diamond structure.

[0011] Furthermore, grooves are provided on both sides of the second convex edge in the diamond structure.

[0012] Furthermore, the length of the first convex edge in the first texture structure is 6mm to 8mm, the length of the second convex edge in the second texture structure is 9mm to 11mm, the width of the second convex edge is 2mm to 4mm, the groove depth is 0.4mm to 0.8mm, and the groove length is 8mm to 12mm.

[0013] Furthermore, the length of the first convex edge in the first texture structure is 6 mm, the length of the second convex edge in the second texture structure is 10 mm, the width of the second convex edge is 3 mm, the depth of the groove is 0.6 mm, and the length of the groove is 10 mm.

[0014] A shoe sole comprises an outer sole. The shoe sole pattern structure for a BMX pedal is arranged on the lower surface of the outer sole, and the pattern structure and the outer sole are arranged as an integrated structure.

[0015] A shoe comprises the above-mentioned sole.

[0016] The sole pattern structure for the BMX pedal of the present invention has the following advantages:

[0017] 1. By providing a first texture structure with diamond-shaped grooves in the first area and a second texture structure with triangular grooves in the second area, the texture structure is engaged with the studs of the BMX pedals and the stability of the fit is maintained, thereby improving sports performance.

[0018] 2. The texture structure is highly compatible with various types of pedals. The triangular groove structure is flexible and stable and can be combined into different shapes to better fit the various shapes of the pedals.

[0019] 3. The soles are all provided with texture structures to increase the fitting rate between the texture structures and the convex studs, so that athletes can quickly complete the fitting between the soles and the pedals.

[0020] 4. The first pattern structure is arranged in a triangular array to prevent athletes from stepping on air and getting injured, and to increase the overall stability of the sole.

[0021] 5. Increase the bending flexibility of the sole by setting grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to better understand the purpose, structure and function of the present invention, the sole pattern structure of the pedal for a bicycle of the present invention is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the BMX pedal 300 has a size of 101.1*97mm and is made of either metal or plastic. There are 14 protruding studs 301 on the pedal 300. The metal version of the pedal 300 can have some of the protrusions removed according to the athlete's preference. However, currently 80% of athletes choose plastic pedals 300, and only 20% choose metal pedals 300 and remove the protruding studs 301 on the pedal 300. The texture structure provided by the present invention can ensure the fit between the entire sole and the protruding studs 301 by laying out the groove structure throughout, and can basically meet the needs of all BMX pedals 300.

[0027] like Figure 2 As shown, the texture structure of the BMX pedal 300 includes a first area 100 and a second area 200, wherein the first area 100 corresponds to the arch of the human midfoot, and the second area 200 is the area outside the first area 100, corresponding to the forefoot and heel of the human foot. A number of triangular grooves are set in the second area 200, and a number of diamond grooves are set in the first area 100. By densely paving the triangular and diamond grooves on the sole, the studs 301 on the BMX pedal 300 can be quickly embedded in the grooves, thereby achieving a fit between the athlete's sole and the pedal 300.

[0028] Specifically, the side of the texture structure close to the inner side of the human foot is defined as the inner side of the texture structure, the side of the texture structure close to the outer side of the human foot is defined as the outer side of the texture structure, the end of the texture structure close to the toe of the human foot is defined as the front of the texture structure, and the end of the texture structure close to the heel of the human foot is defined as the back of the texture structure. After the bicycle pedal 300 is fitted to the sole, the three studs 301 on the front side of the pedal 300 and the 6 to 8 studs 301 in the middle are engaged with the triangular grooves, and the studs 301 on the rear side of the pedal 300 and close to the outer side of the sole are engaged with the diamond grooves. Among them, the triangular grooves themselves have stable characteristics and are not easy to deform. They can be engaged with the studs 301 on the front and middle sides of the pedal 300. Compared with the triangular grooves, the diamond grooves can more effectively disperse pressure when subjected to force, especially the pressure in the front-to-back direction and the inner-outer side direction. While perfectly adapting to the studs 301 on the rear side of the pedal 300, it improves the uniformity of stress distribution of the studs 301 in the grooves, thereby improving the overall stability.

[0029] In order to better understand the purpose, structure and function of the present invention, the sole pattern structure of the BMX pedal of the present invention is further described in detail below with reference to the accompanying drawings, taking the specific structure of the sole pattern structure of the BMX pedal as an example.

[0030] like Figure 2 As shown, the texture structure for the BMX pedal 300 includes a first area 100 and a second area 200 outside the first area 100. The first area 100 is located in the midfoot of the human body. A first texture structure 101 with a plurality of diamond grooves is provided in the first area 100 to engage with the protruding studs 301 on the rear side of the BMX pedal 300. A second texture structure 201 with a plurality of triangular grooves is provided in the second area 200 to engage with the protruding studs 301 on the front side and the middle of the BMX pedal 300.

[0031] The above-mentioned structural setting is adopted because the convex stud 301 of the pedal 300 is a raised cylindrical structure. The triangle has the characteristics of simple structure, stability and not easy to deform. By setting the first texture structure 101 as a triangular groove, which is engaged with the cylindrical convex stud 301, the fit between the sole and the pedal 300 is enhanced, which helps the athlete to control the BMX through the power of the foot.

[0032] It is understandable that the studs 301 can also be triangular or square columnar structures. The first pattern structure 101 is set as a triangular groove to take advantage of the stability and flexible combination of the triangular structure to better fit various shapes on the pedal.

[0033] When controlling the BMX bike to perform movements with the midfoot of an athlete, the foot usually exerts force in the front-to-back longitudinal direction and the inside-outside lateral direction. Therefore, a second texture structure 201 with diamond-shaped grooves is provided in the second area 200. The diagonals of the diamonds are perpendicular to each other and bisect each other, so that the diamonds can disperse the pressure more effectively when subjected to force. When the circle is clamped inside the diamond, the edge of the circle forms multiple points of contact with the edge of the diamond. This contact method helps to increase the stability and strength of the connection. In addition, when the circle is clamped inside the diamond, the stress distribution may be more uniform. The diamond can guide the stress to be dispersed along its diagonal direction, reducing the concentration of local stress, thereby improving the overall stability.

[0034] The second texture structure 201 in this embodiment adopts an equilateral triangle groove to ensure that the convex nail 301 maintains relatively uniform force after being embedded therein. Of course, it can also be set to other triangular structures such as an isosceles triangle, as long as the convex nail 301 can be stably embedded therein.

[0035] Furthermore, the first texture structure 101 of the diamond-shaped groove includes four first convex edges 102, and the second texture structure 201 of the triangular groove includes three second convex edges 202. Since the triangle is the simplest and most basic polygon in a plane figure, it has flexibility and adaptability and can be combined to form other shapes to meet other shape requirements. Therefore, two adjacent second texture structures 201 in the second area 200 share the same second convex edge 202, so that the two second texture structures 201 are spliced ​​together to form a diamond structure, which echoes the diamond-shaped groove of the first texture structure 101 and balances the stress of the entire texture structure.

[0036] Further, such as Figure 3 As shown, grooves 203 are provided on both sides of the second convex edge 202 in the above-mentioned diamond structure. The grooves 203 are arranged horizontally along the direction of the line connecting the inner and outer sides of the texture structure, and are located on the extension line of the second convex edge 202 in the diamond structure. Since the second convex edge 202 in the diamond structure has a certain thickness, when the front and rear ends of the texture structure are bent upward or downward, the bending angle at this position will be limited. By providing the above-mentioned groove 203 structure, the lateral rigidity of the texture structure is reduced, thereby increasing the bending flexibility of the texture structure.

[0037] Preferably, the length of the first flange 102 is smaller than the length of the second flange 202, so that the area of ​​the diamond groove located in the midfoot is smaller, and the gap produced after the engagement with the rear side stud 301 of the pedal 300 is smaller, thereby enhancing the midfoot's ability to control the pedal 300 and improving the athlete's stability and accuracy in controlling the BMX.

[0038] It can be understood that after the convex studs 301 on the rear side of the pedal 300 are engaged with the first texture structure 101, the second convex edge 202 is relatively larger to form a larger triangular groove, and then there is a relatively large gap between the convex studs 301 on the front and middle side of the pedal 300 and the second convex edge 202, which helps the convex studs 301 to quickly embed into the second texture structure 201, thereby achieving a rapid and stable engagement of the texture structure with all the convex studs 301 of the pedal 300, thereby improving the athlete's control stability and athletic performance.

[0039] Preferably, six first texture structures 101 are arranged in the first area 100, and the number gradually decreases from front to back. The texture structures are arranged in the first row, the second row and the third row from the front to the back. Three first texture structures 101 are arranged in the first row, two first texture structures 101 are arranged in the second row, and one first texture structure 101 is arranged in the third row, so that the first texture structures 101 in the first area 100 are arranged in a triangular array as a whole, wherein the two first texture structures 101 near the outside of the first row are perfectly matched with the two convex studs 301 near the outside of the rear side of the foot pedal 300, thereby enhancing the stability of the midfoot. On the one hand, the triangular array arrangement can echo the triangular groove of the sole. On the other hand, if the athlete's midfoot fails to engage the first texture structure 101 in the first row with the corresponding convex stud 301 at the beginning, it will engage it with the first texture structure 101 in the second or third row, thereby avoiding the athlete from stepping on air and getting injured, thereby increasing the overall stability of the sole.

[0040] Combined with the conventional specifications of the current scooter pedal 300, the length is 101.1 mm, the width is 97 mm, the thickness is 21 mm, and the diameter of the protruding nail 301 is 4 mm. The dimensions of the texture structure provided by the utility model are as follows: the length of the first convex edge 102 in the first texture structure 101 is 6 mm to 8 mm, the length of the second convex edge 202 in the second texture structure 201 is 9 mm to 11 mm, the width of the second convex edge 202 is 2 mm to 4 mm, the depth of the groove 203 is 0.4 mm to 0.8 mm, and the length of the groove 203 is 8 mm to 12 mm.

[0041] The preferred dimensions of this embodiment are: the length of the first convex edge 102 in the first texture structure 101 is 6 mm, and the length of the second convex edge 202 in the second texture structure 201 is 10 mm. The diamond groove and triangular groove formed thereby can be engaged with the convex stud 301 on the footrest 300, and there is a smaller gap between the diamond groove and the convex stud 301 after the two are engaged, which increases the fit between the rear side of the footrest 300 and the sole. At the same time, the convex stud 301 on the front side and the middle of the footrest 300 can be quickly and stably engaged with the second texture structure 201. The width of the second convex edge 202 is 3 mm, which helps to maintain the stable state of the convex stud 301 in the second texture structure 201. The depth of the groove 203 is 0.6 mm, and the length of the groove 203 is 10 mm, thereby better reducing the lateral rigidity of the texture structure and enhancing the bending flexibility.

[0042] The utility model also discloses a sole, such as Figure 3 As shown, it includes an outer sole 400, and the texture structure used for the bicycle pedal 300 is set on the lower surface of the outer sole 400, and the texture structure and the outer sole 400 are set as an integrated structure.

[0043] Preferably, the outsole 400 and the texture structure are made of rubber material as a whole, the overall thickness of the rubber is 4mm to 5mm, the thickness of the outsole 400 is 1mm to 2mm, and the hardness is 62A, so that the texture structure fits the bicycle pedal 300 while having good stability and bending flexibility.

[0044] The utility model also provides a pair of shoes, comprising the above-mentioned sole.
