Rotatable anti-slip device and all-terrain anti-slip sole

Abstract

For rotatable cleats and all-terrain cleat soles, the provision of a rotational portion allows the cleat mechanism to be inverted relative to the mounting seat. [Solution] 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 rotating shaft can limit the rotation direction, 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, users can reverse and adjust the friction part according to different terrains to adapt to the anti-slip needs on different terrains, thereby effectively improving the anti-slip effect on various terrains. In addition, the anti-slip device can be easily and conveniently replaced without losing the anti-slip function of the shoe due to accidents or damage.

Description

[Technical Field]

[0001] The present invention relates to the technical field of shoe manufacturing, and more particularly to rotatable cleats and all-terrain anti-skid soles. [Background technology]

[0002] Shoe soles are an important component of shoes and have properties such as abrasion resistance and pressure resistance, with anti-slip function being one of the main functions of the sole. In the prior art, on hard surfaces, the purpose of anti-slip is generally achieved by increasing friction with the sole pattern. However, when the road surface is frozen due to weather such as rain or snow, or when engaging in outdoor sports (mountain climbing, fishing), it is difficult to achieve anti-slip with the sole pattern alone. Anti-slip is usually achieved by inserting spikes into the ground, but walking on hard surfaces in spiked shoes causes discomfort to the feet and makes the spikes more susceptible to damage.

[0003] In existing sports such as mountain climbing, it is necessary to deal with complex terrain, and carrying two pairs of shoes with different soles at the same time can be a major inconvenience. In the prior art, publication numbers US7269916B2 (2005.04.19), EP1558103A1 (2005.08.03), and CN117617628A (2022.08.11) are all patents related to soles with anti-slip devices, but the connection between the anti-slip device and the sole is a two-axis connection for positioning, making assembly inconvenient. Therefore, in order to solve the above problems, it is very necessary to design a rotatable anti-slip device and anti-slip sole. Summary of the Invention [Problem to be solved by the invention]

[0004] (1) The technical problem to be solved

[0005] To solve the above problems of the prior art, the present invention provides a rotatable anti-slip device that can be switched between different anti-slip surfaces to suit different sports scenes, and is easy to adjust and use.

[0006] The present invention further provides a non-slip sole that can be adapted to different sports scenes by adjusting the rotatable non-slip device, making it easy to use. [Means for solving the problem]

[0007] (2) Technical proposal

[0008] To achieve the above objectives, the technical solutions adopted in the present invention include:

[0009] The rotatable anti-skid device includes a device body, the device body including a mounting base and an anti-skid mechanism rotatably connected to the mounting base, the anti-skid mechanism including a friction part and a rotating part connected to the friction part, the rotating part including a sphere and a rotating shaft connected between the sphere and the friction part, the friction part including a first friction surface and a second friction surface facing in the opposite direction to the first friction surface, and the friction part including an anti-skid attachment provided on the second friction surface. In actual implementation, the rotating part allows the anti-skid mechanism to be inverted relative to the mounting base. Specifically, the sphere allows the rotating shaft to rotate along the spherical surface. At the same time, the rotating shaft is provided between the sphere and the friction part, so that the rotating shaft can limit the rotation direction, allowing the friction part to be inverted along the rotating shaft. Because the friction part has a first friction surface and a second friction surface, users can invert and adjust the friction part according to different terrains to meet the anti-skid needs of different terrains, thereby effectively improving the anti-skid effect on various terrains.

[0010] Preferably, the anti-slip attachment includes spikes or spike adhesive pads, the friction part and the rotating part of the anti-slip mechanism are made of TPU material, the anti-slip attachment is made of either tungsten steel or stainless steel, and the friction part, the rotating part and the anti-slip attachment are integrally formed by molding, so that in actual implementation, the anti-slip attachment strengthens the grip of the second friction surface and effectively improves the anti-slip performance.

[0011] Preferably, the anti-slip mechanism is integrally molded. In actual implementation, the anti-slip mechanism is manufactured by one-piece injection molding, which saves assembly time, effectively improves production efficiency of the anti-slip mechanism, and reduces production costs.

In actual implementation, the positioning hole effectively reduces the amount of injection molding material used and facilitates manufacturing, saving production costs for the friction part while also facilitating positioning and installation. The design of the friction strip also makes it easy to support the spike.

[0013] Preferably, the friction part includes a plurality of positioning holes and a plurality of friction strips, and the plurality of friction strips are cross-connected to form an outer rib and an inner cross rib. In actual implementation, the plurality of positioning holes are easily installed, and the connection of the friction part after installation is stronger and more reliable. At the same time, the plurality of friction strips are cross-connected to form an inner cross strip, which supports the friction part and effectively increases the strength of the friction part.

[0014] Preferably, the friction strip is mainly formed by alternating thick convex segments and thin concave segments, the thick convex segments and the thin concave segments are connected end-to-end, and the spikes are disposed on the thick convex segments of the outer rib and the inner cross rib. In actual implementation, when the friction strip is attached to the friction groove segment, the friction strip can be effectively fixed, making the attachment of the friction strip more solid and reliable. At the same time, when the friction groove segment is deformed by force, a wavy surface is formed by the thick convex segments and the thin concave segments, effectively increasing the friction area and preventing the friction strip from escaping from the friction groove segment.

[0015] Preferably, the friction strip further includes a locking protrusion at the second end thereof, extending into the positioning hole. In practice, the locking protrusion at the second end fixes the second end to prevent the rotation axis from moving along the spherical surface after the friction part is installed, thereby making the installation of the friction part more solid and reliable.

[0016] Preferably, the friction strip further includes a protruding point at the second end, the protruding point being located on the first friction surface. In actual practice, when the first friction surface faces outward, the protruding point will contact the ground before the first friction surface and abut against the second end, preventing the second end from escaping from the friction groove segment and effectively protecting the friction strip.

[0017] Preferably, the mounting seat includes a chute that fits over the sphere, the chute having a first opening for the sphere to enter and exit and a second opening for the rotation shaft to escape, the chute having a cylindrical upper portion and a spherical lower portion, the second opening restricting the sphere. In actual implementation, the purpose of providing the first opening is to facilitate assembly of the anti-slip mechanism and the mounting seat, and the second opening is provided to allow the rotation shaft to escape and at the same time restrict the rotation shaft, making the friction part stronger and more stable after installation.

[0018] Preferably, the mounting seat is integrally molded. In actual implementation, the mounting seat is manufactured by one-piece injection molding, which saves assembly time, effectively improves production efficiency of the mounting seat, and reduces production costs.

[0019] Preferably, the mounting seat further includes a relief arc surface for relieving the friction portion, the relief arc surface having an angle of 0 to 60°, and the friction portion rotating along the relief arc surface by an angle of 90 to 120°. In actual implementation, when switching between the first and second friction surfaces is required, the user can move the second end portion to swing the rotating shaft along the second opening, driving the sphere to rotate and causing the friction strip to escape from the friction groove segment, and then rotate the friction strip along the rotating shaft. As the rotating shaft swings along the second opening, the friction portion can move along the relief arc surface, allowing the relief arc surface to relieving the friction portion, making the switching process more efficient and smooth.

[0020] Preferably, the mounting seat includes a taper head for locking and mounting, which in practical implementation process makes it easier to install and fix the mounting seat.

[0021] An anti-slip sole includes a sole body connected to a rotatable anti-slip device, and the sole body includes a mounting groove for mounting the rotatable anti-slip device. In practical implementation, the provision of the mounting groove facilitates the mounting of the anti-slip device.

[0022] Preferably, the mounting groove includes a seat groove segment that fits with the mounting seat, a limit stop wall surrounding the outer periphery of the seat groove segment, and a locking hole provided at the bottom of the seat groove segment, the locking hole being used to fix a locking tapered head. In actual implementation, the engagement between the locking hole and the locking tapered head facilitates the mounting of the mounting seat, making the connection of the mounting seat stronger and more reliable.

[0023] Preferably, the mounting groove further includes an anti-skid groove segment for engaging with the anti-skid mechanism, and the anti-skid groove segment includes a friction groove segment for engaging with the friction strip. In actual implementation, the friction strip is fitted into the friction groove segment after installation, and the friction groove segment facilitates installation of the friction strip and also protects the friction strip.

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

[0025] Preferably, the friction groove segment further includes a groove bottom surface for supporting the friction strip, the groove bottom surface including a concave surface mating with the thick convex segment and a convex surface mating with the thin concave segment. In actual implementation, when the friction strip is attached to the friction groove segment, the friction strip can be effectively fixed, making the attachment of the friction strip more solid and reliable. At the same time, when the friction groove portion 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 preventing the friction strip from escaping from the friction groove portion.

[0026] Preferably, the friction groove segment further includes an insertion hole on the groove bottom surface, and the insertion hole is fitted with an anti-skid attachment. In actual implementation, the insertion hole on the groove bottom surface of the friction groove can accommodate a spike.

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

[0028] Preferably, the sole body further includes a locking groove provided on the positioning protrusion, and the locking groove is fitted with the locking protrusion. In actual implementation, the engagement between the locking groove and the locking protrusion secures the friction part to the sole better and prevents the second end from slipping out.

[0030] Preferably, after the anti-slip device is attached, the protruding point is located on the same plane as the bottom surface of the anti-slip sole. In actual implementation, since the protruding point is located on the same plane as the bottom surface of the anti-slip sole, when the sole contacts the ground, the protruding point contacts the ground before the second end, thereby effectively preventing the second end from unintentionally escaping from the friction groove segment, so that the anti-slip device is firmly and reliably fixed to the anti-slip sole during walking.

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

[0032] Preferably, the sole body includes two or more mounting grooves, and in actual implementation, one mounting groove can be provided in the heel area and another in the forefoot area, so that two rotatable anti-skid devices are provided on one sole, which will achieve better results.

In actual implementation, the provision of the rotating part 122 allows the anti-slip mechanism 12 to be inverted relative to the mounting seat 11. Specifically, the provision of the sphere 123 allows the rotating shaft 124 to rotate along the spherical surface. At the same time, the provision of the rotating shaft 124 between the sphere 123 and the friction part 121 allows the rotating shaft 124 to restrict the rotation direction, so that the friction part 121 can be inverted 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 invert and adjust the friction part 121 according to different terrains to meet the anti-slip needs of different terrains, thereby effectively improving the anti-slip effect on various terrains.

[0051] The anti-slip attachment 127 includes spikes or spike adhesive pads, the friction part 121 and the rotating part 122 of the anti-slip mechanism 12 are made of TPU material, and the anti-slip attachment 127 is made of tungsten steel, and the friction part 121, the rotating part 122 and the anti-slip attachment 127 are integrally formed by molding, and in actual implementation, the anti-slip attachment 127 strengthens the grip force of the second friction surface 126 and effectively improves the anti-slip performance.

[0052] The anti-slip mechanism 12 is integrally molded. In actual implementation, the anti-slip mechanism 12 is manufactured by one-piece injection molding, which saves time for assembling parts, effectively improves production efficiency of the anti-slip mechanism 12, and reduces production costs.

[0053] The friction part 121 includes a positioning hole 128 and a friction strip 129 arranged around the positioning hole 128. The friction strip 129 is connected to the spike. The friction strip 129 includes a first end 1291 connected to the rotating shaft 124 and a second end 1292 corresponding to the first end 1291. In actual implementation, the provision of the positioning hole 128 effectively reduces the amount of injection molding material used and facilitates manufacturing, thereby saving production costs for the friction part 121 and facilitating positioning and installation. The design of the friction strip 129 makes it easy to support the spike.

[0054] The friction part 121 includes a plurality of positioning holes 128 and a plurality of friction strips 129, which are cross-connected to form outer ribs and inner cross ribs. In actual implementation, the positioning holes 128 are easily installed, making the connection of the friction part 121 stronger and more reliable after installation. At the same time, the friction strips 129 are cross-connected to form inner cross strips, which support the friction part 121 and effectively increase the strength of the friction part 121.

In actual implementation, when the friction strip 129 is attached to the friction groove segments 215, the friction strip 129 can be effectively fixed, making the attachment of the friction strip 129 more solid and reliable. At the same time, when the friction groove segments 215 are deformed by force, the thick convex segments 1293 and the thin concave segments 1294 form a wavy surface, which effectively increases the friction area and prevents the friction strip 129 from slipping out of the friction groove segments 215.

In actual implementation, the purpose of providing the first opening 112 is to facilitate the assembly of the anti-slip mechanism 12 and the mounting seat 11 and to allow for simple and convenient replacement without losing the anti-slip function of the shoe due to accident or damage. The second opening 113 is provided to allow the rotation shaft 124 to escape and at the same time restricts the rotation shaft 124, making the friction part 121 stronger and more stable after installation.

[0059] The mounting seat 11 is integrally molded. In actual implementation, the mounting seat 11 is manufactured by one-piece injection molding, which saves time in assembling parts, effectively improves production efficiency of the mounting seat 11, and reduces production costs.

[0078] The mounting groove 21 includes a seat groove segment 211 that fits with the mounting seat 11, a limit stop wall 212 that surrounds the outside of the seat groove segment 211, and a locking hole 213 provided at the bottom of the seat groove segment 211, which is used to secure the locking tapered head 115. In actual implementation, the engagement between the locking hole 213 and the locking tapered head 115 makes the mounting of the mounting seat 11 easier and makes the connection of the mounting seat 11 stronger and more reliable.

In actual implementation, when the friction strip 129 is attached to the friction groove segment 215, the friction strip 129 can be effectively fixed, making the attachment of the friction strip 129 more solid and reliable.

In actual implementation, since the protruding point 1296 is located on the same plane as the bottom surface of the anti-slip sole, when the sole comes into contact with the ground, the protruding point 1296 will contact the ground before the second end 1292, thereby effectively preventing the second end 1292 from unintentionally escaping from the friction groove segment 215, so that the anti-slip device is firmly and securely fixed to the anti-slip sole during walking.

[0087] The mounting groove 21 further includes an undercut groove 2101, and the friction groove segment 215 is connected between the undercut groove 2101 and the rotation groove segment 2141.

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

[0103] All-terrain anti-slip sole usage method A

[0104] When used on snow, the provision of the rotating part 122 allows the anti-slip mechanism 12 to be inverted relative to the mounting seat 11. Specifically, the provision of the sphere 123 allows the rotating shaft 124 to rotate along the spherical surface. At the same time, the provision of the rotating shaft 124 between the sphere 123 and the friction part 121 allows the rotating shaft 124 to restrict the rotation direction, so that the friction part 121 can be inverted 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 invert 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 anti-slip sole usage method B

[0106] When used in wetlands, the provision of the rotating part 122 allows the anti-slip mechanism 12 to be inverted relative to the mounting seat 11. Specifically, the provision of the sphere 123 allows the rotating shaft 124 to rotate along the spherical surface. At the same time, the provision of the rotating shaft 124 between the sphere 123 and the friction part 121 allows the rotating shaft 124 to restrict the rotation direction, so that the friction part 121 can be inverted 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 invert and adjust the friction part 121 according to different terrains to adapt to wetlands, thereby effectively improving the anti-slip effect in wetlands.

[0107] All-Terrain Non-Slip Shoe Sole Assembly / Replacement Method C

[0108] When assembling, the entire anti-slip mechanism 12 is fitted into the anti-slip groove segment 214, and then the mounting seat 11 is attached to the seat groove segment 211. As the locking tapered head 115 on the mounting seat 11 is locked into 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, sliding along the upper cylindrical structure of the chute section 111 to the lower spherical structure, restricting rotation, and the rotating shaft 124 is fitted 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 then fitted into the shoe sole together to complete the assembly process. The adoption of single-axis positioning improves the convenience of the assembly process and allows for simple and convenient replacement without risking the loss of the shoe's anti-slip function due to accidents or damage. When replacing, the anti-slip device is forcefully pulled out of the mounting groove 21, and then the above steps are carried out. After the assembly of the anti-slip mechanism 12 is completed, 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 limited, thereby completing the installation and replacement process.

[0109] The above is merely an example of the present invention, which does not limit the patent scope of the present invention, and any equivalent transformations made using the contents of the specification and drawings of the present invention, or equivalent transformations directly or indirectly applied to other related technical fields, are also included in the scope of patent protection of the present invention.
