Description

Technical Field

[0001] The present invention relates to the technical field of shoe manufacturing, and particularly to a rotatable anti-slip device and an all-terrain anti-slip shoe sole.

Background Art

[0002] The shoe sole, as an important component of shoes, has characteristics such as wear resistance and pressure resistance, and the anti-slip function is one of the main functions of the shoe sole. In the prior art, on hard road surfaces, it is common to increase the frictional force through the pattern of the shoe sole to achieve the anti-slip purpose. However, when the road surface is frozen due to weather such as rain or snow, or in cases such as outdoor sports (mountaineering, fishing), it is difficult to achieve anti-slip only with the pattern of the shoe sole. Usually, spikes are inserted into the ground to achieve anti-slip. However, when walking on a hard road surface wearing spike shoes, it causes discomfort to the feet and the spikes are easily damaged.

[0003] In existing sports such as mountaineering, it is necessary to cope with complex road surfaces, and carrying two different shoes on the soles of both feet also causes great inconvenience. In the prior art, publication numbers US7269916B2 (April 19, 2005), EP1558103A1 (August 3, 2005), and CN117617628A (August 11, 2022) are all patents related to shoe soles with anti-slip devices. The connection between the anti-slip device and the shoe sole is a biaxial connection for positioning, and the assembly is inconvenient. Therefore, in order to solve the above problems, it is very necessary to design a rotatable anti-slip device and an anti-slip shoe sole.

[0006] This invention further provides an anti-slip shoe sole that can be adapted to different sports scenes and is easier to use by adjusting a rotatable anti-slip device. [Means for solving the problem]

In the actual implementation process, by providing the rotating part, the anti-slip mechanism can be reversed relative to the mounting base, specifically, by providing the sphere, the rotating shaft can rotate along the surface of the sphere, and at the same time, by providing the rotating shaft between the sphere and the friction part, the direction of rotation of the rotating shaft can be restricted, so that the friction part can be reversed along the rotating shaft, and since the friction part has a first friction surface and a second friction surface, the user can reverse and adjust the friction part according to different terrains to adapt to anti-slip needs on different terrains, thereby effectively improving the anti-slip effect on various terrains.

[0010] Preferably, the anti-slip attachment includes spikes or adhesive pads for spikes, the friction and rotating parts in the anti-slip mechanism are made of TPU material, the anti-slip attachment is made of either tungsten steel or stainless steel, the friction part, rotating part and anti-slip attachment are integrally molded by mold processing, and in the actual implementation process, the anti-slip attachment enhances the grip force of the second friction surface and effectively improves the anti-slip performance.

[0011] Preferably, the anti-slip mechanism is integrally molded. In the actual implementation process, since the anti-slip mechanism employs an integral injection molding method, assembly time for parts can be saved, the production efficiency of the anti-slip mechanism can be effectively improved, and production costs can be reduced.

[0012] Preferably, the friction portion includes a positioning hole and a friction strip provided around the positioning hole, the friction strip being connected to a spike, and the friction strip including a first end connected to a rotating shaft and a second end corresponding to the first end. In the actual implementation process, providing a positioning hole can effectively reduce the amount of injection molding material used, simplify manufacturing, save production costs for the friction portion, and simultaneously facilitate positioning and mounting. The design of the friction strip makes it easier to support the spike.

[0013] Preferably, the friction portion includes a plurality of positioning holes and a plurality of friction strips, the plurality of friction strips intersecting and connected to form an outer rib and an inner cross rib. In the actual implementation process, the plurality of positioning holes are easily installed, and after installation, the connection of the friction portion becomes stronger and more reliable, and at the same time, the plurality of friction strips intersecting and connected to form an inner cross strip, supporting the friction portion and effectively increasing its strength.

[0014] Preferably, the friction strip is formed mainly by alternating thick convex segments and thin concave segments, with the ends of the thick convex and thin concave segments connected to each other, and the spikes are positioned on the thick convex segments of the outer ribs and inner cross ribs. In the actual implementation process, when the friction strip is attached to the friction groove segment, the friction strip can be effectively fixed, thereby making the attachment of the friction strip stronger and more reliable. At the same time, when the friction groove segment is deformed by force, a corrugated surface is formed by the thick convex and thin concave segments, effectively increasing the friction area and preventing the friction strip from coming off the friction groove segment.

[0015] Preferably, the friction strip further includes a locking projection provided at the second end and extending toward the interior of the positioning hole. In the actual implementation process, the locking projection at the second end fixes the second end in order to prevent the axis of rotation from moving along the spherical surface after the friction part is mounted, thereby making the mounting of the friction part more robust and reliable.

[0016] Preferably, the friction strip further includes a protruding point provided at a second end, the protruding point being located on the first friction surface. In the actual implementation process, if the first friction surface is facing outward, the protruding point will contact the ground before the first friction surface and abut against the second end, preventing the second end from slipping out of the friction groove segment and effectively protecting the friction strip.

[0017] Preferably, the mounting seat includes a chute portion that engages with a sphere, the chute portion having a first opening for the sphere to enter and exit and a second opening for the rotation axis, the chute portion having a cylindrical upper section and a spherical lower section, and the second opening restricts the sphere. In the actual implementation process, the purpose of providing the first opening is to facilitate the assembly of the anti-slip mechanism and the mounting seat, the second opening is provided to relieve the rotation axis and at the same time restricts the rotation axis, thereby making the friction portion more robust and stable after mounting.

[0018] Preferably, the mounting seat is integrally molded. In the actual implementation process, since the mounting seat is made using an integral injection molding method, assembly time for the parts can be saved, the production efficiency of the mounting seat can be effectively improved, and production costs can be reduced.

In the actual implementation process, if it is necessary to switch between the first and second friction surfaces, the user can move the second end to swing the axis of rotation along the second opening, drive the sphere to rotate, and further move the friction strip out of the friction groove segment, and then rotate the friction strip along the axis of rotation, and as the axis of rotation swings along the second opening, the friction portion can move along the direction of the relief arc surface, and the relief arc surface can escape from the friction portion, so the switching process becomes more efficient and smoother.

[0020] Preferably, the mounting seat includes a locking tapered head for fixing and mounting. In the actual implementation process, the provision of a locking tapered head facilitates the mounting and fixing of the mounting seat.

[0021] A non-slip shoe sole, the non-slip shoe sole comprising a shoe sole body connected to a rotatable anti-slip device, the shoe sole body comprising a mounting groove for attaching the rotatable anti-slip device. In the actual implementation process, the provision of the mounting groove facilitates the attachment of the anti-slip device.

[0022] Preferably, the mounting groove includes a seat groove segment that engages with the mounting seat, a limit stopper wall surrounding the outside of the seat groove segment, and a locking hole provided at the bottom of the seat groove segment, the locking hole being used to secure a locking tapered head. In the actual implementation process, the engagement of the locking hole with the locking tapered head facilitates the mounting of the mounting seat and provides a stronger and more reliable connection of the mounting seat.

[0023] Preferably, the mounting groove further includes an anti-slip groove segment that engages with an anti-slip mechanism, and the anti-slip groove segment includes a friction groove segment that engages with a friction strip. In the actual implementation process, the friction strip is fitted into the friction groove segment after it has been mounted, and the friction groove segment facilitates the mounting of the friction strip and can also protect the friction strip.

[0024] Preferably, the friction groove segment includes a side wall for restricting the friction strip, the side wall being higher than the friction strip, with a height difference of 2 to 3.5 mm. In the actual implementation process, the restricting effect of the side wall effectively fixes the friction strip, resulting in a stronger connection of the friction strip.

[0025] Preferably, the friction groove segment further includes a groove bottom surface for supporting the friction strip, and the groove bottom surface includes a concave surface that fits with the thick convex segment and a convex surface that fits with the thin concave segment. In the actual implementation process, when attaching the friction strip to the friction groove segment, the friction strip can be effectively fixed, thereby making the attachment of the friction strip stronger and more reliable. At the same time, when the friction groove part is deformed by force, a wavy surface is formed by the thick convex segment and the thin concave segment, effectively increasing the friction area and avoiding the escape of the friction strip from the friction groove part.

[0026] Preferably, the friction groove segment further includes an insertion hole provided on the groove bottom surface, and the insertion hole fits with the anti-slip accessory. In the actual implementation process, the insertion hole on the groove bottom surface of the friction groove can accommodate the spikes.

[0027] Preferably, the mounting groove further includes a positioning protrusion that fits with the positioning hole. In the actual implementation process, the fitting of the positioning hole and the positioning protrusion facilitates the fixing and mounting of the friction groove part.

[0028] Preferably, the sole body further includes a locking groove provided on the positioning protrusion, and the locking groove fits with the locking protrusion. In the actual implementation process, the fitting of the locking groove and the locking protrusion better fixes the friction part to the sole and prevents the escape of the second end.

[0029] Preferably, the anti-slip groove segment further includes a rotating groove segment that fits with the rotating part, and the rotating groove segment is connected between the friction groove segment and the seat groove segment.

[0030] Preferably, after the anti-slip device is attached, the protruding point is positioned on the same plane as the bottom surface of the anti-slip sole. In the actual implementation process, because the protruding point is positioned on the same plane as the bottom surface of the anti-slip sole, the protruding point contacts the ground before the second end during the process of the sole contacting the ground, effectively preventing the second end from unintentionally slipping out of the friction groove segment, thereby ensuring that the anti-slip device is firmly and securely fixed to the anti-slip sole during walking.

[0031] Preferably, the mounting groove further includes a relief groove, and the friction groove segment is connected between the relief groove and the rotation groove segment. In the actual implementation process, the relief groove can accommodate a finger to facilitate the escape of the second end and to facilitate switching between the first and second friction surfaces.

[0032] Preferably, the sole body includes two or more mounting grooves. In the actual implementation process, one mounting groove can be provided in the heel and another in the forefoot, and since two rotatable anti-slip devices are provided on the sole of one shoe, a better effect can be obtained. [Effects of the Invention]

[0033] (3) Beneficial effects

[0034] The beneficial effects of the present invention are as follows: In the actual implementation process, by providing a rotating part, the anti-slip mechanism can be reversed relative to the mounting base. Specifically, by providing a sphere, the rotating shaft can rotate along the spherical surface. At the same time, by providing the rotating shaft between the sphere and the friction part, the direction of rotation of the rotating shaft can be restricted, so the friction part can be reversed along the rotating shaft. Since the friction part has a first friction surface and a second friction surface, the user can reverse and adjust the friction part according to different terrains to adapt to anti-slip needs on different terrains, thereby effectively improving the anti-slip effect on various terrains. Furthermore, the anti-slip device can be easily and conveniently replaced without losing the anti-slip function of the shoe due to an accident or damage. [Brief explanation of the drawing]

[0102] (Method of using all-terrain non-slip shoe soles according to the embodiment of the present invention)

[0103] Method of use for all-terrain non-slip shoe soles: A

[0104] When used on snow, the anti-slip mechanism 12 can be reversed relative to the mounting base 11 by providing a rotating part 122. Specifically, by providing a sphere 123, the rotating shaft 124 can rotate along the spherical surface. At the same time, by providing the rotating shaft 124 between the sphere 123 and the friction part 121, the rotation direction of the rotating shaft 124 can be restricted, so the friction part 121 can be reversed along the rotating shaft 124. Since the friction part 121 has a first friction surface 125 and a second friction surface 126, the user can reverse and adjust the friction part 121 according to different terrains to adapt to snow, thereby effectively improving the anti-slip effect on snow.

[0105] All-terrain non-slip sole usage method B

[0106] When used in wetlands, the anti-slip mechanism 12 can be reversed relative to the mounting base 11 by providing a rotating part 122. Specifically, by providing a sphere 123, the rotating shaft 124 can rotate along the surface of the sphere. At the same time, by providing the rotating shaft 124 between the sphere 123 and the friction part 121, the direction of rotation of the rotating shaft 124 can be restricted, so the friction part 121 can be reversed along the rotating shaft 124.

[0107] All-terrain non-slip sole assembly / replacement method C

[0108] When assembling, the entire anti-slip mechanism 12 is fitted into the anti-slip groove segment 214, then the mounting seat 11 is attached to the seat groove segment 211, and as the locking tapered head 115 on the mounting seat 11 engages with the locking hole 213 in the seat groove segment 211, the sphere 123 on the anti-slip mechanism 12 is fitted into the first opening 112 of the mounting seat 11, slides along the upper cylindrical structure of the chute portion 111 to the lower spherical structure, restricting rotation, and the rotating shaft 124 fits into the second opening 113 of the mounting seat 11, thereby connecting the mounting seat 11 and the anti-slip mechanism. The mechanism 12 is fitted together with the sole of the shoe, completing the assembly process. Because it employs single-axis positioning, the convenience of the assembly process is improved, and it can be easily and conveniently replaced without losing the anti-slip function of the shoe due to accidental damage. When replacing, the anti-slip device is forcefully pulled out from the mounting groove 21, and then the above steps are performed. After the assembly of the anti-slip mechanism 12 is complete, the mounting seat 11 is pushed into the seat groove segment 211 with a tool or by hand, and the rotating part 122 of the anti-slip mechanism 12 is fixed and restricted, thereby completing the installation and replacement process.
