Description

Technical Field

[0001] This utility model relates to the field of sports shoe technology, and in particular to a lightweight sports shoe with a spliced ​​sole. Background Technology

[0002] Athletic shoes are footwear specifically designed for various sports activities, serving purposes such as foot protection, providing comfort, and enhancing athletic performance. The design and materials of athletic shoes vary depending on the type of sport and the user's needs, such as running shoes, basketball shoes, and soccer shoes, to provide optimal support and protection. Modern athletic shoes often also feature fashionable and personalized designs to meet the needs and tastes of different consumers.

[0003] Existing athletic shoe uppers typically consist of multiple layers of materials, such as lining, filling, and outer leather. Because the overall shape of the upper needs to be maintained, the breathability of the multi-layered upper is poor. Therefore, we need to consider new upper combination methods to reduce the weight of the shoe and improve its breathability. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a lightweight sports shoe with a spliced ​​sole. It uses an elastic and supportive upper as the inner lining and a breathable and lightweight outer covering as the outer skin. This can reduce the overall weight of the shoe and achieve the effect of breathability. The support upper and the outer covering are bonded together with adhesive and then connected to the sole. The horizontally through-holes also help to reduce the overall weight of the sole. The ventilation grooves on the support upper are used to achieve breathability.

[0006] This utility model provides a lightweight sports shoe with a spliced ​​sole, including a hollow sole, a supporting upper, and a covering upper. The covering upper covers the supporting upper and is connected to the hollow sole. The hollow sole has a horizontal through-hole. The supporting upper has a U-shaped tongue fixing opening. Around the tongue fixing opening, the supporting upper has several ventilation grooves spaced apart. One end of the ventilation groove is connected to the tongue fixing opening, and the other end of the ventilation groove extends to the supporting upper. Existing athletic shoe uppers typically consist of multiple layers of materials, including an inner lining, filling, and outer leather. Because maintaining the overall shape of the upper is crucial, the breathability of these multiple layers is often poor. A solution is to replace the filling, which provides shaping, with a more elastic and supportive upper as the lining, and a more breathable and lightweight outer upper. This reduces the overall weight of the shoe while improving breathability. The support and outer uppers are bonded together with adhesive before being attached to the sole. Horizontally perforated holes further reduce the overall weight of the sole, and ventilation grooves on the support upper enhance breathability.

[0007] In some embodiments, the overlay covers the ventilation slots. To maintain the overall shape of the upper and prevent the skin on the instep from being directly exposed to the outside, the overlay fabric provides protection and coverage.

[0008] In some embodiments, the upper covering is provided with a U-shaped groove, the position of which corresponds to the position of the tongue fixing opening, and a reinforcing piece extends from the upper covering around the U-shaped groove. The U-shaped groove corresponds to the position of the tongue fixing opening, leaving space for the tongue to be fixed, and the extended reinforcing piece is preferably made of PU leather to increase strength and provide support for the later insertion of shoelaces.

[0009] In some embodiments, the supporting upper has perforations around the tongue fixing opening, and the reinforcing plate also has perforations. The perforations on the tongue fixing opening and the reinforcing plate are staggered, with the perforations on the reinforcing plate located above the ventilation groove. The perforations are used for inserting shoelaces, adjusting and tightening the upper. The staggered perforations, one on the supporting upper and one on the reinforcing plate, form a row that effectively combines the supporting and covering uppers, achieving a tightening effect while preventing them from separating.

[0010] In some embodiments, the support upper is formed in one piece by 3D printing and is made of TPEE. The 3D printing technology used for the support upper allows for faster molding, eliminating the need for complex manufacturing processes while maintaining its support, while the choice of TPEE material balances flexibility and support.

[0011] In some embodiments, the overlay upper is a mesh-like breathable fabric. This mesh-like breathable fabric effectively improves airflow within the shoe, keeping feet dry and comfortable. Mesh-like breathable fabrics are widely used in the art, and their specific structures can be found in existing technologies, which will not be elaborated upon here.

[0012] In some embodiments, the front end of the reinforcing piece is connected to a shoe tongue, which extends rearward and is located within the shoe tongue fixing opening. The design of providing a shoe tongue on the shoe upper is a common feature in the prior art and will not be elaborated upon here.

[0013] In some embodiments, an anti-deformation plate, made of epoxy resin, is provided around the perforated sole along its side. The epoxy resin anti-deformation plate, positioned around the perforated hole, provides additional support and prevents the sole from deforming under pressure, thus offering auxiliary support.

[0014] In some embodiments, the perforated sole has drainage holes on its bottom surface, located at the center of the sole and connected to the perforation. The sidewalls of the drainage holes are angled. The added drainage holes reduce the weight of the sole while providing drainage. The connection to the perforation and the angled sidewalls help alleviate pressure differences. During exercise, the sole is compressed, air is expelled, and a pressure difference arises between the drainage holes and the ground, which can easily cause noise. Therefore, the perforated holes for side ventilation and the angled sidewalls help alleviate pressure differences and reduce energy loss during exercise.

[0015] In some embodiments, a shock-absorbing pad is attached to the bottom surface of the hollowed-out sole. The shock-absorbing pad has through holes, the positions of which correspond to the drainage holes. The shock-absorbing pad is made of TPU material. The TPU material provides good elasticity and wear resistance. The through holes, positioned to correspond to the drainage holes, do not affect the normal operation of the drainage holes. Preferably, the shock-absorbing pad has a textured, wear-resistant pattern to increase the friction of the sole and provide an anti-slip effect.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This invention uses an elastic and supportive upper as the inner lining of the shoe, and a breathable and lightweight outer covering as the outer skin. This reduces the overall weight of the shoe and achieves breathability. The support upper and the outer covering are bonded together with adhesive and then connected to the sole. The horizontally perforated holes also help reduce the overall weight of the sole. The ventilation grooves on the support upper are used to achieve breathability.

[0040] According to some embodiments of the present invention, the present invention provides a lightweight sports shoe with a spliced ​​sole, including a hollow sole 1, a supporting upper 2, and a covering upper 3. The covering upper 3 covers the supporting upper 2 and is connected to the hollow sole 1. The hollow sole 1 has a horizontally penetrating hollow hole 11. The supporting upper 2 is provided with a U-shaped tongue 32 fixing opening 21. Around the tongue 32 fixing opening 21, the supporting upper 2 is provided with several ventilation grooves 22 spaced apart. One end of the ventilation groove 22 is connected to the tongue 32 fixing opening 21, and the other end of the ventilation groove 22 extends to the supporting upper 2. In the existing technology, the upper of sports shoes is usually made of multiple layers of materials such as inner lining, filling cotton and outer leather. Because it is necessary to maintain the basic shape of the upper, the breathability of the multi-layered upper is not good. It is considered to replace the filling cotton that plays a plastic role on the upper and use a support upper 2 with elasticity and strong support as the inner lining, and a cover upper 3 with strong breathability and light weight as the outer leather. This can reduce the overall weight of the shoe and achieve the effect of breathability. The support upper 2 and the cover upper 3 are bonded together with adhesive and then connected to the sole. The horizontally through-hole 11 is also used to reduce the overall weight of the sole. The ventilation grooves 22 on the support upper 2 are used to achieve the breathability performance.

[0041] The upper 3 covers the ventilation slot 22. To maintain the overall shape of the upper and prevent the skin on the instep from being directly exposed to the outside world, the ventilation slot 22 is covered with fabric to provide protection and cover.

[0042] The hollow sole 1 has an anti-deformation plate 12 around the hollow hole 11 on its side. The anti-deformation plate 12 is made of epoxy resin. The epoxy resin anti-deformation plate 12 is arranged around the hollow hole 11 to increase the support of the hollow hole 11 and prevent the sole from deforming under pressure, thus playing an auxiliary support role.

[0043] Reference Figure 3 , Figure 3 This is a top view schematic diagram of the overall structure of the sports shoe in some embodiments of this utility model.

[0044] According to some embodiments of this utility model, optionally, a U-shaped groove is provided on the upper 3, the position of which corresponds to the fixing opening 21 of the tongue 32, and a reinforcing piece 31 extends around the U-shaped groove on the upper 3. The U-shaped groove corresponds to the fixing opening 21 of the tongue 32, leaving a fixing position for the tongue 32. The extended reinforcing piece 31 is preferably made of PU leather to increase the firmness and provide support for the later insertion of shoelaces.

[0045] The supporting upper 2 has perforations around the fixing opening 21 of the tongue 32, and the reinforcing plate 31 also has perforations. The perforations on the tongue 32 fixing opening 21 and the reinforcing plate 31 are staggered, with the perforations on the reinforcing plate 31 located above the ventilation groove 22. The perforations are used for inserting shoelaces, adjusting and tightening the upper. The staggered perforations, one on the supporting upper 2 and one on the reinforcing plate 31, form a row, effectively combining the supporting upper 2 and the covering upper 3, achieving a tightening effect while preventing them from separating.

[0046] The supporting upper 2 is formed in one piece by 3D printing and is made of TPEE. The 3D printing technology used in the supporting upper 2 makes it faster to form, and it maintains its support without the need for complicated production processes, while the choice of TPEE material takes into account both flexibility and support.

[0047] The upper 3 is made of a mesh-like breathable fabric. This mesh-like breathable fabric effectively improves airflow within the shoe, keeping feet dry and comfortable. Mesh-like breathable fabrics are widely used in this field; their specific structure can be found in existing technologies and will not be elaborated upon here.

[0048] The front end of the reinforcing piece 31 is connected to the tongue 32, which extends rearward and is located in the tongue 32 fixing opening 21. The design of setting the tongue 32 on the shoe upper is a common setting in the prior art, and will not be described in detail here.

[0049] Reference Figure 4 , Figure 4 This is a schematic diagram of the hollowed-out shoe sole structure in some embodiments of this utility model.

[0050] According to some embodiments of this utility model, optionally, a drainage hole 13 is provided on the bottom surface of the hollow sole 1. The drainage hole 13 is located at the center of the hollow sole 1 and is connected to the hollow hole 11. The side wall of the drainage hole 13 is inclined. The added drainage hole 13 reduces the weight of the sole while realizing the drainage function. The connection with the hollow hole 11 and the inclined side wall are used to alleviate pressure difference. During exercise, the sole is pressed down by pressure, and the air in the sole is discharged. A pressure difference is generated between the drainage hole 13 and the ground, which can easily produce abnormal noise. Therefore, the hollow hole 11 with side ventilation and the inclined side wall are provided to alleviate pressure difference and reduce energy loss during exercise.

[0051] The hollow sole 1 has a shock-absorbing plate 14 attached to its bottom surface. The shock-absorbing plate 14 has through holes, the positions of which correspond to the drainage holes 13. The shock-absorbing plate 14 is made of TPU material. The TPU material used in the spliced ​​shock-absorbing plate 14 provides good elasticity and wear resistance. The through holes on the shock-absorbing plate 14, corresponding to the drainage holes 13, do not affect the normal operation of the drainage holes 13. Preferably, the shock-absorbing plate 14 has a textured, wear-resistant pattern to increase the friction of the sole and provide an anti-slip effect.
