Description

Technical Field

[0001] The invention relates to a shoe sole, in particular to an anti-skid spike movably installed on the shoe sole, and is applied to unpaved roads, wet places with moss or algae, and the like. Background Art

[0002] The influence of climate, such as plum rain, typhoon, thunderstorm and winter rain, makes the original road surface slippery, not to mention mountainous areas or coastal dikes. In particular, the wet road conditions that have been shielded from sunlight for many years have grown moss everywhere, and the stones by the stream, coastal dikes / wave-breaking blocks have grown moss and algae due to long-term soaking. For the above natural environment and the public also likes to go mountaineering / hiking or activities such as streams and coasts, it is necessary to choose suitable shoes for the slippery road conditions to reduce the risk of accidental slips.

[0003] The patterns on the soles of ordinary sneakers or sports shoes are sufficient for daily walking on roads and suitable sports venues. However, in the above-mentioned suburban unpaved and slippery roads, or environments covered with moss or algae, you need to wear anti-slip shoes. Anti-slip shoes are shoes with anti-slip spikes fixed on the soles, such as Taiwan Invention Patent No. I705771 mountaineering shoes, which provide anti-slip effect through anti-slip spikes.

[0004] The aforementioned patent has its defects in use. First, the nail heads of the anti-skid spikes are fixed to the inner position of the sole and are covered by other foam structures of the sole. Therefore, the anti-skid spikes are basically fixed to the sole and cannot be removed. Once the anti-skid spikes are worn or damaged, the anti-skid effect is reduced and they cannot be replaced in time, which makes it easy to cause slip accidents. Second, the anti-skid spikes of the shoes are fixed at the toes and heels, that is, the arrangement position of the anti-skid spikes is fixed and cannot be adjusted after leaving the factory. For walking on different road conditions, for example, when it is necessary to focus on the toes or heels to land first, it has the defect of insufficient applicability in use. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a sole with movable anti-skid spikes, which is convenient for users to install and remove the anti-skid spikes, thereby achieving simple and rapid replacement of new products.

[0006] The technical solution adopted by the present invention to solve the technical problem is: A shoe sole with movable anti-skid spikes comprises: a shoe sole having a ground-facing side facing the ground, the ground-facing side comprising a forefoot area and a heel area, the forefoot area and the heel area being provided with spike grooves, and the outer edges of the notches of the spike grooves being located on the ground-facing side; and anti-skid spikes having an outer thread on their outer diameter surfaces, and the anti-skid spikes being selected and screwed into the spike grooves of the forefoot area or the heel area; the anti-skid spikes having an inner buried end and an anti-skid end in opposite directions, and the anti-skid spikes enter the spike grooves from the ground-facing side with the inner buried end, and the anti-skid end is provided with a driving groove in the direction of the inner buried end, so that a tool can be clamped against the driving groove and drive the anti-skid spikes to rotate radially so as to load and unload the anti-skid spikes in the spike grooves.

[0007] Through the above configuration and structural technology, users can use tools to install and remove anti-slip spikes. When worn anti-slip spikes need to be replaced, users can easily and quickly replace them with new ones. In addition, whether the toe part or the heel part needs anti-slip performance, the user can adjust the installation position of the anti-slip spikes according to the needs, and has a variety of applicable options.

[0008] The anti-skid spikes of the present invention are made of high-carbon high-chromium alloy steel. The anti-skid spikes used in the known anti-skid shoes are only ordinary steel, which cannot effectively prevent slipping when facing a slippery road. The anti-skid spikes of the present invention are made of high-carbon high-chromium alloy steel, which has a higher hardness than the hardness of the road surface. Therefore, when walking on a slippery road, the anti-skid spikes can bite the ground to produce an anti-skid effect.

[0009] The beneficial effect of the present invention is that it is convenient for users to install and remove the anti-slip spikes, so that the replacement of new products can be completed simply and quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figures 1 to 5 As shown in the figure, a shoe sole with movable anti-skid spikes is disclosed, which comprises: a shoe sole 100, which has a ground-facing side 110 facing the ground, the ground-facing side 110 includes a forefoot area 111 and a heel area 112, the forefoot area 111 and the heel area 112 are provided with spike grooves 113, and the outer edge of the notch of the spike groove 113 is located on the ground-facing side 110; and an anti-skid spike 200, the outer diameter surface of which is provided with an external thread 201, and the anti-skid spike 200 is selected and screwed into the spike groove 113 of the forefoot area 111 or the spike groove 113 of the heel area 112; the anti-skid spike 200 has an inner buried end 201 in opposite directions. 10 and an anti-slip end 220, and the anti-slip nail 200 enters the nail groove 113 from the direction of the ground side 110 with the embedded end 210, and the anti-slip end 220 is provided with a driving groove 221 towards the embedded end 210, so that a tool can be clamped against the driving groove 221 and drive the anti-slip nail 200 to rotate radially to load and unload the anti-slip nail 200 in the nail groove 113, and adjust the anti-slip end 220 to be located in the nail groove 113 without being exposed (the anti-slip nail 200 is in a completely embedded state) or the anti-slip end 220 is exposed outside the notch of the nail groove 113 (the anti-slip nail 200 is in a protruding and visible use state).

[0021] When the present invention is actually used, through the above structure and configuration, tools are provided to carry out the installation and removal (installation and removal) of the anti-slip spikes 200. When the worn anti-slip spikes 200 need to be replaced, the user can simply remove them from the sole 100 and quickly install the new ones, providing replacement between the old and new ones. In addition, whether the anti-slip performance of the toe part or the heel part is required, the user can install the anti-slip spikes 200 in the forefoot area 111 (such as Figure 3 ) or heel area 112 (as shown Figure 4 The nail groove 113 is positioned as shown in the figure, thereby providing various adjustment options for applicability.

[0022] The anti-skid spike 200 of the present invention is made of high-carbon high-chromium alloy steel, and the hardness of the finished product is as high as HRC 62, and the anti-deformation physical property of the anti-skid spike 200 is better than the anti-deformation physical property of the material of the sole 100. The anti-skid spike 200 of the present invention is made of the high-carbon high-chromium alloy steel material selected above, and its hardness is generally higher than the walking ground. When walking on slippery roads, the anti-skid spike 200 can cause slight surface damage to the ground, thus forming a user experience that the anti-skid spike 200 bites the ground, thereby producing an anti-skid effect.

[0023] The detailed features of each component of the present invention and the effects that can be achieved are further described in detail. The sole 100 includes a buffer portion 120 and an anti-skid portion 130, and the two are made of different materials. The buffer portion 120 is provided with a groove 121 for the anti-skid portion 130 to be integrally connected; the nail groove 113 is provided on the anti-skid portion 130. The anti-skid portion 130 is mainly used to contact the ground, and the anti-skid portion 130 provides stable contact when stepping on the ground, and anti-skid grooves can be provided on the anti-skid portion 130. The buffer portion 120 provides the user with the function of absorbing the reaction force from the ground when stepping on it, greatly reducing the risk of injury, and also has the effect of stable support.

[0024] In the embodiment of the present invention, the buffer portion 120 is made of a foam material, such as EVA (Ethylene VinylAcetate), PU (Polyurethanes) or TPU (ThermoplasticPolyurethane); and the anti-slip portion 130 is made of a rubber material, which not only has excellent anti-slip effect, but also has wear resistance and waterproof properties.

[0025] like Figure 6 , Figure 7As shown, before the anti-slip stud 200 is screwed into the stud groove 113 for the first time, the groove surface of the stud groove 113 is a flat annular surface, and the diameter of the stud groove 113 is smaller than the maximum outer diameter of the anti-slip stud 200; when the anti-slip stud 200 is screwed into the stud groove 113 for the first time, the groove surface of the stud groove 113 is cut to form an inner thread 114 corresponding to the outer thread 201. With the above structural configuration, the user can use the anti-slip stud 200 for general daily wear when not in use. When facing slippery road conditions, moss, and algae, the anti-slip stud 200 can be installed on the stud groove 113 of the sole 100 manually or with the help of tools. In addition, Figure 7 The anti-skid end 220 of the disclosed adjustable anti-skid spike 200 is exposed outside the notch of the spike groove 113 (the anti-skid spike 200 is in a protruding and visible state in use).

[0026] In addition, the nail groove 113 is disposed in the anti-slip portion 130, and the nail groove 113 can also be connected to the buffer portion 120. Figure 8 As shown, the user can adjust the anti-skid end 220 to be located in the nail groove 113 without being exposed (the anti-skid nail 200 is completely embedded), which is particularly suitable for walking on flat or paved roads to avoid unnecessary wear of the anti-skid nail 200. Since the anti-skid nail 200 does not need to be completely removed from the sole 100, there is no need to find a place to store the anti-skid nail 200 after removing the anti-skid nail 200 from the sole 100, and there is no need to worry about the risk of losing the anti-skid nail 200 due to careless storage.

[0027] See also Figure 5 As shown, the anti-skid end 220 has anti-skid protrusions 222 arranged in an interval ring, and the driving groove 221 is located between the anti-skid protrusions 222. Through the structural configuration between the driving groove 221 and the anti-skid protrusions 222, a fine multi-point pattern can be formed on the anti-skid end 220 of each anti-skid stud 200, providing each anti-skid stud 200 with multiple fine bite structures, which helps to improve the anti-skid effect during use. The driving groove 221 is located between the anti-skid protrusions 222, which can not only be used as a tool to engage and push the anti-skid stud 200 to drive the radial rotation, but also be used for drainage (especially helpful for walking on slippery roads), so that the driving groove 221 has both disassembly and drainage.

[0028] Furthermore, the driving groove 221 is connected to the outer diameter surface of the anti-skid nail 200 and is radial. Through the above structural configuration, when the user walks, water can be quickly discharged outward toward the outer diameter surface of the anti-skid nail 200, which greatly reduces the concentration of water adhering to the driving groove 221 when stepping on it and affects the friction force, thereby facilitating the rapid drainage effect.

[0029] In addition, the anti-skid protrusion 222 is located at the outer side of the anti-skid end 220 in the radial direction. The anti-skid protrusion 222 is gradually expanded from the anti-skid end 220 to the embedded end 210. With the above structural configuration, the anti-skid protrusion 222 has good structural strength, which is conducive to stable travel on slippery roads covered with moss or algae.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
