Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a nested sole and the sports shoe thereof. Background Technology

[0002] Athletic shoes are shoes designed and manufactured specifically for people participating in sports or travel. Unlike ordinary leather or rubber shoes, the soles of athletic shoes are generally soft and elastic, providing cushioning. They enhance elasticity during exercise and some even help prevent ankle injuries. Therefore, athletic shoes are essential for most sports activities, especially high-intensity physical activities such as basketball, running, and various everyday exercises.

[0003] Currently, people are paying more and more attention to health, and users are becoming more and more enthusiastic about outdoor sports, such as jogging. When running or exercising, the wear layer of the sole of sports shoes suffers the most damage, especially for sports enthusiasts. Often, the sole is severely worn, but the upper is still intact and the shock absorption performance of the cushioning layer has not deteriorated. Discarding a pair of shoes like this would be wasteful.

[0004] To address these issues, we propose a nested sole and a sports shoe based on it. Summary of the Invention

[0005] The purpose of this invention is to provide a nested sole and the sports shoe thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nested shoe sole, comprising:

[0007] The outsole consists of an abrasion layer and a base layer from bottom to top, and the abrasion layer is detachably connected to the bottom of the base layer for contact with the sole surface;

[0008] The edge of the wear-resistant layer is integrally provided with a positioning strip, and the middle of the wear-resistant layer is integrally provided with a reinforcing strip. The reinforcing strip and the positioning strip are detachably inserted into the bottom surface of the substrate. The bottom of the wear-resistant layer is fixed by bolts, and an injection hole is opened in the middle of the bolts. The glue passes through the reinforcing strip and the positioning strip to fix the edge and the middle, so that the wear-resistant layer is stably assembled on the bottom surface of the substrate.

[0009] As an alternative to the nested sole of the present invention, the base is set as a popcorn foam sole.

[0010] As an alternative to the nested sole of the present invention, the wear-resistant layer is a rubber layer with a thickness between 0.3cm and 0.8cm.

[0011] As an optional embodiment of the nested sole of the present invention, the positioning insert has a shoe-plate-shaped annular structure along the edge of the wear-resistant layer, and a gap of at least 1 cm is left at the edge of the wear-resistant layer to form an adhesive edge.

[0012] The reinforcing strip is configured as a strip structure and is arranged along the central axis of the wear-resistant layer.

[0013] As an optional embodiment of the nested sole of the present invention, the bottom edge of the base is provided with a first slot in conjunction with the positioning insert, and the middle part of the base is provided with a second slot in conjunction with the reinforcing strip.

[0014] The positioning insert is inserted into the first slot;

[0015] The reinforcing strip is inserted into the second slot.

[0016] As an optional embodiment of the nested sole of the present invention, wherein: the bottom of the wear-resistant layer is provided with a groove, and a plurality of grooves are provided along the wear-resistant layer from the toe to the heel, and a through hole penetrating the wear-resistant layer is provided in the middle of each groove;

[0017] The bottom of the base has several threaded holes that mate with the perforations. The shank of the bolt is threaded into the threaded hole through the perforation, and the head of the bolt is placed in the groove. A rubber sealing sheet is applied to the end of the groove to seal the bolt.

[0018] As an optional embodiment of the nested sole of the present invention, wherein: the shank end of the bolt is spaced apart from the inner top of the threaded hole, the first slot and the second slot are connected to the top of the threaded hole through a guide hole, the positioning insert is spaced apart from the inner top of the first slot, and the reinforcing strip is spaced apart from the inner top of the second slot.

[0019] As an alternative embodiment of the nested sole of the present invention, wherein the head of the bolt is provided with an arc-shaped first hook hole.

[0020] As an alternative to the nested sole of the present invention, the positioning insert has a second hook hole at the toe of the shoe, which is a circular hole.

[0021] An athletic shoe includes a sole, on which an upper is attached by adhesive stitching and, together with an abrasion-resistant layer, forms the shoe body.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. A wear-resistant layer is detachably connected to the base of the sole. The wear-resistant layer is spliced ​​and guided by positioning inserts and reinforcing strips, and is reinforced by bolts with injection holes. The injection of glue passes through the positioning inserts and reinforcing strips to fix the connection structure, so that the wear-resistant layer is stably assembled on the bottom surface of the base for the sole to contact the ground when walking.

[0024] 2. Hook holes are made in the bolts and wear-resistant layer, which can be hooked off from the outside to remove the bolts and wear-resistant layer from the base. The foam base is highly flexible and can be removed from the groove of the base to fix the rubber strip, which is convenient for replacing the wear-resistant layer, improving the service life of the shoes and saving replacement costs.

[0038] In this embodiment 1, the positioning insert 4 has a shoe-like ring structure along the edge of the wear-resistant layer 3, and leaves a gap of at least 1cm at the edge of the wear-resistant layer 3 to form an adhesive edge 6, which is used to seal the edge of the wear-resistant layer 3 with adhesive base 7.

[0039] Furthermore, the reinforcing strip 5 is configured as a strip structure and arranged along the central axis of the wear-resistant layer 3.

[0040] In this embodiment 1, the bottom edge of the base 7 is provided with a first slot 8 in conjunction with the positioning insert 4, and the middle part of the base 7 is provided with a second slot 9 in conjunction with the reinforcing strip 5.

[0041] The positioning insert 4 is inserted into the first slot 8;

[0043] That is, by interlocking the positioning insert 4 and the reinforcing strip 5 on the base 7, the wear-resistant layer 3 is quickly positioned and interlocked on the base 7 for assembly, and preliminary interlocking and fixing is performed at the edges and center.

[0044] In this embodiment 1, a groove 10 is provided at the bottom of the wear-resistant layer 3. Several grooves 10 are provided along the wear-resistant layer 3 from the toe to the heel. A through hole 11 is provided in the middle of each groove 10 to penetrate the wear-resistant layer 3.

[0045] The bottom of the base 7 is provided with several threaded holes 12 to match the various through holes 11. The shank end of the bolt 14 is threaded into the threaded hole 12 through the through hole 11. The head of the bolt 14 is placed in the groove 10. At the port of the groove 10, the bolt 14 is sealed by a rubber sealing sheet 16 to prevent it from loosening and falling off due to contact with foreign objects.

[0046] In this embodiment 1, the shank end of the bolt 14 is spaced from the inner top of the threaded hole 12. The first slot 8 and the second slot 9 are connected to the top of the threaded hole 12 through the guide hole 13. The positioning insert 4 is spaced from the inner top of the first slot 8, and the reinforcing strip 5 is spaced from the inner top of the second slot 9.

[0047] During assembly, glue is filled through the glue injection hole 15 of bolt 14, and the glue fills the gap, allowing the wear-resistant layer 3 to be inserted into the part of the base 7 for fixed connection, improving the stability of the connection structure and preventing the wear-resistant layer 3 from detaching during walking.

[0048] In this embodiment 1, the head of the bolt 14 is provided with an arc-shaped first hook hole 17, which can be used to hook and rotate the bolt 14 to remove it.
