Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoemaking technology, and in particular to a sole component and a finished shoe. Background Technology
[0002] The sole assembly refers to the combination of the sole and the heel counter. One existing manufacturing process involves separately manufacturing the sole and heel counter. When producing the heel counter separately, a 1-2 mm thick elastic sheet is inserted into a pre-made heel counter sleeve. The elastic sheet and the heel counter sleeve are then heat-fused to form the heel counter. The produced heel counter is then trimmed, with workers manually cutting off any protruding edges. The sole and heel counter are then placed separately in a mold, which is used to heat them and fuse them together. However, in this process, the sole and heel counter rely solely on the positioning mechanism inside the mold for positioning. During the trimming process, uneven areas may appear along the bottom edge of the heel counter. This can cause misalignment and displacement when the heel counter overlaps the sole surface in the mold, resulting in quality problems at the joint of the produced sole assembly. Utility Model Content
[0003] The purpose of this utility model is to provide a sole component and a finished shoe to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] First, this utility model provides a shoe sole component, including:
[0006] The sole and heel counter are a component with left and right wings and a rear wall. The left and right wings are located in front of the rear wall, and the left and right wings and the rear wall together form a space that can surround the heel of the human foot.
[0007] The bottom of the left and right wings extends downward with a first extension portion, and the bottom of the rear wall extends downward with a second extension portion.
[0008] The heel portion of the sole is provided with a first connecting portion extending downward on the left and right sides, and a second connecting portion extending downward at the rear.
[0009] During welding, the first extension is located in the first connecting part, the second extension is located in the second connecting part, the bottom of the heel counter abuts against the top of the sole, there is a gap between the first connecting part and the first extension, and there is also a gap between the second connecting part and the second extension.
[0010] When producing the shoe sole assembly, the heel counter and sole provided by this utility model are produced separately. When the two are fused together using a mold, the separately produced heel counter and sole are sham-assembled. The first extension is inserted into the first connecting part, the second extension is inserted into the second connecting part, and then the sham-assembled shoe sole assembly is placed into the molding mold to fuse the heel counter and sole together.
[0011] The sole assembly provided by this solution, during the initial assembly process, uses the cooperation between the first extension and the first connecting part, and the cooperation between the second extension and the second connecting part, to provide preliminary positioning for the sole assembly to be formed. Working in conjunction with the positioning mechanism inside the mold, this prevents displacement of the heel counter during the forming process with the sole, avoiding quality issues at the connection point between the heel counter and the sole. Furthermore, in addition to the bottom of the heel counter fusing with the sole, the first extension and the first connecting part also partially fuse together during the fusing process. Some of the molten adhesive flows downwards, forming anchor points between the first extension and the first connecting part. Similarly, the second extension and the second connecting part also form anchor points. These anchor points on the sole are distributed in a triangular pattern, further enhancing stability. Compared to simply fusing the lower edge of the heel counter with the top of the sole, the sole assembly provided by this invention offers a higher quality, more stable connection between the heel counter and the sole, making it less prone to detachment. It is understood that both the first connecting part and the second connecting part are located within the edge of the sole, and the outer wall of the bottom of the heel counter coincides with the rear edge of the sole.
[0012] As an extension of the above solution, the wall thickness of the bottom of the heel counter is 3 mm to 5 mm. This design provides both good support and a snug fit. When the bottom of the heel counter abuts against the sole, the contact area between the heel counter and the sole is relatively increased, making it less prone to displacement and resulting in a more stable connection. Furthermore, this solution ensures that the first and second extensions have appropriate thicknesses, making them less prone to breakage and improving connection stability.
[0013] As an extension of the above solution, the first extension is wedge-shaped, with its narrow end located on the front side of the left and right wings, and the first connecting part is a rectangular groove. The size of the rectangular groove is adapted to the first extension. When the heel counter abuts against the sole, the walls at both ends of the first extension, the walls at both ends of the left and right sides, and the bottom all abut against the rectangular groove. This arrangement ensures that the first extension and the rectangular groove are not perfectly shaped, leaving unfilled space inside the groove. Part of the molten adhesive generated during the welding process remains in this space, connecting the lower part of the first extension to the sole, thus improving connection stability. It is understood that the first extension does not completely melt during the welding process; only the portion near the bottom of the heel counter melts. Because the walls at both ends of the first extension, the walls at both ends of the left and right sides, and the bottom all abut against the rectangular groove, the first extension will not shift in either the front-back or left-right directions, ensuring positioning accuracy.
[0014] As an extension of the above solution, the second extension is hemispherical, the second connecting part is a circular hole, and the bottom of the second extension abuts against the bottom of the second connecting part. With this arrangement, the second extension can be easily inserted into the second connecting part during sham assembly.
[0015] As an extension of the above solution, the heel counter includes a heel counter sleeve and an elastic insert wrapped by the heel counter sleeve. The elastic insert is a thermoplastic component. The first extension and the second extension are both disposed on the elastic insert and integrally formed with the elastic insert. This allows the first extension and the second extension to be integrally formed with the elastic component, reducing production difficulty while ensuring connection stability. During the production of the heel counter, both the first extension and the second extension are fused to the heel counter sleeve. During the fusion of the heel counter and the sole, some of the colloid generated by the melting of the colloid inside and outside the heel counter sleeve flows downward and fuses with the heel counter sleeve, especially with the gaps between the fabric of the heel counter sleeve, forming several intersecting connection points, improving connection stability.
[0016] As an extension of the above solution, the elastic insert is provided with several through holes extending in the front-to-back direction. This can increase the air permeability of the elastic insert.
[0017] As an extension of the above solution, the upper surface of the sole inside the first connecting part is provided with several drainage channels extending in the front-to-back direction. One end of each drainage channel is located between the rear side of the second connecting part and the rear end of the sole, and the other end of each drainage channel is located in the area of the sole corresponding to the human toes. During welding, some of the adhesive flows into the drainage channels, reinforcing the stability of the connection between the heel counter and the sole. The drainage channels also improve the flexibility of the sole. When a person's foot steps on the sole, the drainage channels are compressed, making the sole more prone to deformation. Furthermore, in finished shoes, the insoles are often made of absorbent materials or have vertically arranged drainage holes. When the sole component provided in this application is applied to finished shoes, the sweat produced by the human feet can be guided into the drainage channels, reducing the moisture level of the insole. Although the sweat is guided to the area on the sole corresponding to the human toes, since sweating is not excessive under normal circumstances, sweat produced in other parts of the foot will not exacerbate the moisture level of the toes.
[0018] As an extension of the above solution, the area of the sole corresponding to the toes of the foot is provided with several vertically extending drainage holes, which are connected to the drainage channel. This allows sweat in the drainage channel to be discharged through the drainage holes. It is understood that shoe soles are generally designed with a lower front and higher back, and the drainage channel is also designed with a lower front and higher back. Even if the drainage channel is set horizontally, when a person walks and the forefoot strikes the ground, the drainage channel will still change to a lower front and higher back position, allowing sweat to still be discharged through the drainage holes.
[0019] As an extension of the above solution, the edge at the connection between the drain hole and the drainage channel is chamfered. This accelerates the removal of sweat.
[0020] Based on the above solutions, this utility model also provides a finished shoe, which has a sole component and an upper based on any of the above solutions or a combination of the above solutions. Since the finished shoe provided by this solution utilizes the sole component provided by the above solutions, it also possesses all the beneficial effects inherent in the sole component provided by the above solutions.
[0021] The sole component provided by this utility model has accurate positioning during molding, which can improve the connection quality between the heel counter and the sole, improve support performance and service life. When the sole is applied to the production of finished shoes, it can wick away sweat. The sole component and finished shoes provided by this utility model belong to the field of shoe manufacturing technology and are applied to the production of finished shoes.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0032] Reference Figures 1 to 4 The following are several embodiments of a shoe sole component and a finished shoe according to the present invention.
[0033] like Figures 2 to 4 As shown, a shoe sole assembly includes:
[0034] The sole 100 and the heel counter 200 are components with left and right wings and a rear wall. The left and right wings are located in front of the rear wall, and the left and right wings and the rear wall together form a space that can surround the heel of the human foot.
[0035] The bottom of the left and right wings extends downward with a first extension 201, and the bottom of the rear wall extends downward with a second extension 202.
[0036] The heel portion of the sole 100 is provided with a first connecting portion 101 extending downward on the left and right sides, and a second connecting portion 102 extending downward at the rear.
[0037] During welding, the first extension 201 is located in the first connecting part 101, the second extension 202 is located in the second connecting part 102, the bottom of the heel counter 200 abuts against the top of the sole 100, there is a gap between the first connecting part 101 and the first extension 201, and there is also a gap between the second connecting part 102 and the second extension 202.
[0038] When producing the shoe sole assembly, the heel counter 200 and the sole 100 provided by this utility model are produced separately. When the two are fused together using a mold, the separately produced heel counter 200 and sole 100 are sham-assembled. The first extension 201 is inserted into the first connecting part 101, and the second extension 202 is inserted into the second connecting part 102. Then, the sham-assembled shoe sole assembly is placed into the molding mold to fuse the heel counter 200 and sole 100 together.
[0039] The sole assembly provided in this solution, during the initial assembly process, utilizes the engagement of the first extension 201 with the first connecting part 101 and the engagement of the second extension 202 with the second connecting part 102 to provide preliminary positioning for the sole assembly to be formed. Working in conjunction with the positioning mechanism inside the mold, this prevents displacement of the heel counter 200 during the forming process with the sole 100, avoiding quality issues at the connection point between the heel counter 200 and the sole 100. Furthermore, besides the bottom of the heel counter 200 being fused to the sole 100, the first extension 201 and the... During the welding process, the first connecting portion 101 will also partially fuse together, with some of the molten adhesive flowing downwards, forming an anchor point between the first extension portion 201 and the first connecting portion 101. Similarly, the second extension portion 202 and the second connecting portion 102 also form anchor points. Furthermore, the anchor points formed on the sole 100 are distributed in a triangular pattern, further enhancing stability. Compared to simply welding the lower edge of the heel counter 200 to the top of the sole 100, the connection between the heel counter 200 and the sole 100 in the sole assembly provided by this invention is of higher quality, more stable, and less prone to detachment. It is understood that both the first connecting portion 101 and the second connecting portion 102 are located within the outer edge of the sole 100, and the outer wall of the bottom of the heel counter 200 coincides with the rear edge of the sole 100.
[0040] In this embodiment, the wall thickness of the bottom of the heel counter 200 is 3 mm to 5 mm. This design provides both good support and a snug fit. When the bottom of the heel counter 200 contacts the sole 100, the contact area between the heel counter 200 and the sole 100 is relatively increased, making displacement less likely and the connection more stable. Furthermore, this design ensures that the first extension 201 and the second extension 202 have appropriate thicknesses, making them less prone to breakage and improving connection stability.
[0041] The heel counter 200 includes a heel counter sleeve 203 and an elastic insert 204 enclosed by the heel counter sleeve 203. The elastic insert 204 is a thermoplastic component. The first extension 201 and the second extension 202 are both disposed on the elastic insert 204 and integrally formed with the elastic insert 204. This allows the first extension 201 and the second extension 202 to be integrally formed with the elastic insert 204, reducing production difficulty while ensuring connection stability. During the production of the heel counter 200, the first extension 201 and the second extension 202 are fused to the heel counter sleeve 203. During the fusion of the heel counter 200 and the sole 100, some of the colloid generated by the melting of the colloid inside and outside the heel counter sleeve 203 flows downward and fuses with the heel counter sleeve 203, especially with the gaps between the fabric of the heel counter sleeve 203, forming several intersecting connection points, improving connection stability.
[0042] The elastic insert 204 is provided with several through holes extending in the front-to-back direction. This increases the breathability of the elastic insert 204.
[0043] In some embodiments, the first extension 201 is wedge-shaped, with its narrow end located on the front side of the left and right wings, and the first connecting portion 101 is a rectangular groove. The size of the rectangular groove is adapted to the first extension 201. When the heel counter 200 abuts against the sole 100, the walls at both ends of the first extension 201, the walls at both ends of the left and right sides, and the bottom all abut against the rectangular groove. This arrangement ensures that the first extension 201 and the rectangular groove are not perfectly shaped, leaving unfilled space inside the groove. Part of the molten adhesive generated during the welding process remains in this space, connecting the lower portion of the first extension 201 to the sole 100, thus improving the connection stability. It is understood that the first extension 201 does not completely melt during the welding process; only the portion near the bottom of the heel counter 200 melts. Since the walls at both ends of the first extension 201, the walls at both ends of the left and right sides, and the bottom all abut against the rectangular groove, the first extension 201 will not shift in the front-back direction or the left-right direction, thus ensuring positioning accuracy.
[0044] Furthermore, the second extension 202 is hemispherical, the second connecting portion 102 is a circular hole, and the bottom of the second extension 202 abuts against the bottom of the second connecting portion 102. With this arrangement, the second extension 202 can be easily inserted into the second connecting portion 102 during assembly.
[0045] In some embodiments, the upper surface of the sole 100 inside the first connecting portion 101 is provided with a plurality of drainage grooves 103 extending in the front-rear direction. One end of each drainage groove 103 is located between the rear side of the second connecting portion 102 and the rear end of the sole 100, and the other end of each drainage groove 103 is located in the area of the sole 100 corresponding to the toes of the human foot. During welding, some of the adhesive flows into the drainage grooves 103, reinforcing the stability of the connection between the heel counter 200 and the sole 100. The drainage grooves 103 also enhance the variability of the sole 100. When a person's foot steps on the sole 100, the drainage grooves 103 are partially squeezed, making the sole 100 more prone to deformation. Furthermore, in finished shoes, the insoles are often made of absorbent materials or have vertically arranged permeable holes. When the sole components provided in this application are applied to finished shoes, the sweat produced by the feet can be guided into the drainage channel 103, reducing the dampness of the insole. Although the sweat will be guided to the area corresponding to the toes on the sole, since there is not much sweating under normal circumstances, the sweat produced in other parts of the foot will not aggravate the dampness of the toes.
[0046] Furthermore, the sole 100 has several vertically extending drainage holes 104 in the area corresponding to the toes, which are connected to the drainage channel 103. This allows sweat in the drainage channel 103 to be drained through the drainage holes 104. It is understood that the sole 100 is generally designed with a lower front and higher back, and the drainage channel 103 is also designed with a lower front and higher back. Even if the drainage channel 103 is set horizontally, when a person walks and the forefoot strikes the ground, the drainage channel 103 will still change to a lower front and higher back position, allowing sweat to still be drained through the drainage holes.
[0047] In this embodiment, the edge at the connection between the drain hole 104 and the drainage channel 103 is chamfered. This accelerates the excretion of sweat.
[0048] like Figure 1 As shown, based on the above embodiments, the present invention also provides a finished shoe, which includes an upper and a sole assembly provided in any of the above embodiments or combinations thereof. By applying the sole assembly, the finished shoe provided by the present invention has the advantages of a stable connection between the heel counter and the sole, a long service life, and the ability to wick away sweat.
[0049] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
