Description

Technical Field

[0001] The utility model relates to a sole. Background Art

[0002] The grip performance of the sole has a direct impact on human movement, especially in sports such as badminton, tennis, table tennis, etc. that require fast movement, change of direction, and turning, as well as running, rope skipping, etc., which have high requirements for landing stability. Stronger sole grip can increase the friction between the sole and the ground, enhance the stability of the athlete's body during exercise, thereby better controlling the body coordination and improving sports performance. At the same time, excellent sole grip can significantly reduce the torsion injury caused by foot sliding, while providing better stability and support, reducing the potential risks caused by loss of balance or poor posture. It can be seen that the grip of the sole is not only closely related to sports performance, but also closely related to the safety and health of athletes. At present, there are few sports soles with strong grip and taking into account multiple sports on the market, and many designs for enhancing the grip of the sole are still in the theoretical stage, most of which are cumbersome in design and complex in process, and are not suitable for mass production and commercial sale.

[0029] The following is a further detailed description of the specific implementations of the present invention in conjunction with the accompanying drawings. These implementations are only used to illustrate the present invention, but not to limit the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a sole, which comprises an outsole 1 and a midsole 2. The outsole 1 is arranged at the bottom of the midsole 2 and comprises a plurality of honeycomb-shaped, neatly and closely arranged gripping units 3. Figure 3 and Figure 4 As shown, each grip unit 3 includes a regular hexagonal prism 33, a regular hexagonal pyramid 31 disposed at the bottom of the regular hexagonal prism 33, and six polyhedrons 32 evenly spaced along the periphery of the regular hexagonal prism 33. The regular hexagonal pyramid 31 includes a cone tip 311 disposed downward, which generates extremely strong friction when in contact with the ground, thereby enhancing the grip of the outsole 1.

[0034] The polyhedron 32 includes a straight portion 321 arranged on the outside away from the regular hexagonal prism 33 and a bent portion 322 arranged on the inside close to the regular hexagonal prism 33. The straight portion 321 includes a fourth plane extending straight and arranged vertically, and six straight portions 321 surround a first regular hexagonal prism; the bent portion 322 includes a first plane 3221 and a second plane 3222 connected in a > shape, the angle between the first plane 3221 and the second plane 3222 is 120°, and the boundary line between the two faces a side edge 331 of the regular hexagonal prism 33, and the six bent portions 322 surround a second regular hexagonal prism. The same side of the straight portion 321 and the bent portion 322 is connected by an inclined third plane 323, and each polyhedron 32 includes two symmetrically arranged third planes 323.

[0035] The first regular hexagonal prism, the second regular hexagonal prism and the regular hexagonal prism 33 are coaxially arranged from outside to inside. The second regular hexagonal prism is arranged in the same direction as the regular hexagonal prism 33, that is, the side edges of the second regular hexagonal prism are arranged opposite to the side edges 331 of the regular hexagonal prism 33; the first regular hexagonal prism is not arranged in the same direction as the regular hexagonal prism 33 and the second regular hexagonal prism. Compared with the regular hexagonal prism 33 and the second regular hexagonal prism, the rotation angle of the first regular hexagonal prism is 30°, that is, the central axis of each straight portion 321 is opposite to a side edge 331 of the regular hexagonal prism 33.

[0036] The first regular hexagonal prism and the second regular hexagonal prism are arranged in different directions, so that the outsole 1 can be ensured to have good grip and stability in all directions. When the outsole 1 touches the ground, according to the principle of force decomposition, the stress in each direction will be decomposed into the shear force on the polyhedron 32 and the impact force on the ground after acting on the grip unit 3. Since the regular hexagonal structure has stable geometric properties, the shear force on the polyhedron 32 can be evenly dispersed, thereby reducing the distortion and deformation of the grip unit 3 and ensuring the overall stability. Furthermore, the height of the polyhedron 32 is less than the sum of the heights of the regular hexagonal prism 33 and the regular hexagonal pyramid 31. During the landing process of the outsole 1, the cone tip 311 of the regular hexagonal pyramid 31 will first contact the ground and generate extremely strong friction, thereby enhancing the grip performance of the outsole 1. Specifically, the height of the polyhedron 32 is 2.5 mm, and the sum of the heights of the regular hexagonal prism 33 and the regular hexagonal pyramid 31 is 2.6 mm.

[0037] In a specific embodiment of the present invention, the outsole 1 is made of thermosetting polyurethane elastomer.

[0038] The utility model enhances the stability and support of the foot by enhancing the grip of the sole, provides a basis for ensuring sports performance, and can better ensure the safety of the human body during exercise.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
