Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a transparent polyurethane shoe sole. Background Technology

[0002] Currently, rubber is the most common material used to manufacture shoe soles. However, rubber soles are relatively heavy. To improve the lightness of soles, existing technology uses polyurethane. However, the cushioning performance of polyurethane still does not meet the requirements. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a transparent polyurethane shoe sole, comprising three parts: a shoe outsole assembly, a foamed polyurethane infused midsole, and an air cushion assembly. The shoe outsole assembly is made of non-foamed polyurethane material. After molding, the air cushion assembly is placed in the air cushion limiting groove, and then foamed polyurethane is infused onto the shoe outsole assembly to form a foamed polyurethane infused midsole. This integrated, multi-layered shoe sole results in a lightweight overall sole. Only the upper needs to be installed to form the entire shoe. The internal air cushion assembly provides excellent shock absorption. Furthermore, the main body of the shoe outsole assembly is made of transparent polyurethane material, enabling the production of a transparent shoe sole and enhancing its aesthetic design. This effectively solves the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transparent polyurethane shoe sole, comprising:

[0005] The shoe outsole assembly includes a transparent polyurethane outsole, water channels, anti-slip ridges, air cushion limiting grooves, and friction patterns. The transparent polyurethane outsole has water channels evenly spaced on its outer bottom periphery, and anti-slip ridges evenly spaced along its bottom edge. The anti-slip ridges and water channels are distributed alternately. The upper side of the transparent polyurethane outsole has air cushion limiting grooves, and the bottom surface of the transparent polyurethane outsole has friction patterns.

[0006] The upper connecting component is installed on the top edge of the transparent polyurethane outsole;

[0007] The air cushion assembly is installed in the air cushion limiting groove;

[0008] The foamed polyurethane infused midsole is located at the bottom of the upper connecting component, and the bottom of the foamed polyurethane infused midsole connects to the upper side of the transparent polyurethane outsole and the air cushion component.

[0009] First, transparent polyurethane material is poured into a mold to form a transparent polyurethane outsole. The poured transparent polyurethane outsole has water channels, anti-slip ridges, air cushion limiting grooves, and friction patterns. The anti-slip ridges and friction patterns increase ground friction, thus preventing slippage. When water is stepped on, the water is drained through adjacent anti-slip ridges and water channels, preventing water accumulation between the sole and the ground on wet surfaces and reducing friction, further improving the anti-slip effect of the sole. The upper connecting component is used to stably connect the shoe to the upper with adhesive. The air cushion component can improve the cushioning effect of the sole, making it suitable for sports. The foamed polyurethane infused midsole seals the upper side of the transparent polyurethane outsole and air cushion component. The low density of the foamed polyurethane infused midsole makes the shoes more comfortable to wear.

[0010] Furthermore, the outsole assembly also includes X-shaped grooves. The top edge of the transparent polyurethane outsole has X-shaped grooves spaced at equal intervals, and these grooves are located on the bottom inner side of the upper connecting assembly. When foamed polyurethane is poured into the transparent polyurethane outsole to form a foamed polyurethane insole, the X-shaped grooves can increase the contact area between the foamed polyurethane insole and the transparent polyurethane outsole, improving the connection strength between them. During the pouring of foamed polyurethane into the transparent polyurethane outsole, the upper connecting assembly also serves to limit the movement of the foamed polyurethane, helping to maintain the shape of the foamed polyurethane insole.

[0011] Furthermore, the outsole assembly also includes protruding posts, which are evenly distributed at the front end of the top face of the transparent polyurethane outsole. These protruding posts also increase the contact area between the foamed polyurethane insulated midsole and the transparent polyurethane outsole, enhancing the connection strength between the front end of the foamed polyurethane insulated midsole and the transparent polyurethane outsole.

[0012] Furthermore, the upper connecting assembly includes an upper connecting ring, a raised edge, an adhesive annular groove, and an upper fixing annular groove. The top edge of the transparent polyurethane outsole is integrally formed and connected to the bottom end of the upper connecting ring. The upper connecting ring has an upper fixing annular groove on its inner side in the middle. The top inner side of the upper connecting ring is integrally formed and connected to a raised edge. The inner side of the raised edge has an adhesive annular groove. When installing the upper, the bottom edge of the upper is inserted into the upper fixing annular groove. Adhesive is applied between the upper connecting ring and the upper. The adhesive annular groove on the upper fixing annular groove and the raised edge can better accommodate the adhesive, allowing more adhesive between the upper connecting ring and the upper, thus improving the bonding strength between the upper connecting ring and the upper.

[0013] Furthermore, the upper connecting assembly also includes midsole reinforcement grooves. These grooves are evenly spaced along the bottom inner side of the upper connecting ring. The midsole reinforcement grooves connect to the side of the polyurethane foam-infused midsole, and the top surface of the polyurethane foam-infused midsole is lower than the bottom surface of the upper fixing annular groove. During polyurethane foam infusion, the polyurethane foam enters the midsole reinforcement grooves, which increase the contact area between the upper connecting ring and the polyurethane foam-infused midsole, making the connection between the polyurethane foam-infused midsole and the bottom inner side of the upper connecting ring more stable.

[0014] Furthermore, the air cushion assembly includes an upper air cushion layer, a lower air cushion layer, and reinforcing anchor points. The edges of the upper and lower air cushion layers are connected to form the air cushion body, which is filled with air. The upper and lower air cushion layers are connected by evenly distributed reinforcing anchor points. The air cushion body, composed of the upper and lower air cushion layers, can absorb shocks, and the reinforcing anchor points can enhance the connection strength between the upper and lower air cushion layers, thereby improving the overall robustness of the air cushion assembly.

[0015] Furthermore, the system also includes a deformation cavity assembly, which comprises strip-shaped grooves and cavity sealing pads. Two strip-shaped grooves are formed on the upper surface of the transparent polyurethane outsole, located in front of the air cushion limiting groove. Cavity sealing pads are positioned on the upper surface of the transparent polyurethane outsole corresponding to the two strip-shaped grooves. The cavity sealing pads prevent polyurethane foam from entering the strip-shaped grooves during injection, creating a cavity between the forefoot and toe of the molded sole, facilitating bending at this point and improving walking comfort.

[0016] Compared with existing technologies, the beneficial effects of this transparent polyurethane sole are:

[0017] 1. The transparent polyurethane sole consists of three parts: an outsole assembly, a foamed polyurethane infused midsole, and an air cushion assembly. The outsole assembly is made of non-foamed polyurethane material. After the outsole assembly is formed, the air cushion assembly is placed in the air cushion limiting groove, and then foamed polyurethane is infused to form the foamed polyurethane infused midsole. This integrated multi-layer sole makes the sole relatively lightweight. Only the upper needs to be installed to form the entire shoe.

[0018] 2. The transparent polyurethane sole has an internal air cushion component, which provides good shock absorption. The main body of the outsole component is made of transparent polyurethane material, which can make the sole transparent and enhance the appearance design of the sole. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, please refer to Figures 1 to 7 This utility model provides a technical solution: a transparent polyurethane shoe sole, including a shoe outsole component 1, a shoe upper connecting component 2, an air cushion component 4, and a foamed polyurethane infused midsole 5.

[0029] The outsole assembly 1 includes a transparent polyurethane outsole 11, water channels 12, anti-slip ridges 13, air cushion limiting grooves 17, and friction patterns. Water channels 12 are evenly spaced on the outer periphery of the bottom of the transparent polyurethane outsole 11. Anti-slip ridges 13 are evenly spaced along the edge of the bottom surface of the transparent polyurethane outsole 11. The anti-slip ridges 13 and water channels 12 are alternately distributed. An air cushion limiting groove 17 is provided on the upper side of the transparent polyurethane outsole 11. Friction patterns are provided on the bottom surface of the transparent polyurethane outsole 11.

[0030] The friction texture includes arc-shaped raised texture 14, circular raised texture 15, and strip-shaped raised texture 16. Multiple arc-shaped raised textures 14 are provided on the front bottom side of the transparent polyurethane outsole 11, circular raised textures 15 are provided on the rear bottom side of the transparent polyurethane outsole 11, and strip-shaped raised texture 16 is provided in the middle of the bottom of the transparent polyurethane outsole 11. The arc-shaped raised textures 14, circular raised textures 15, and strip-shaped raised texture 16 can increase the friction between the transparent polyurethane outsole 11 and the ground.

[0031] The upper connecting component 2 is installed on the top edge of the transparent polyurethane outsole 11;

[0032] Air cushion assembly 4 is installed in air cushion limiting groove 17;

[0033] The polyurethane foam infused midsole 5 is located at the bottom of the upper connecting component 2, and the bottom of the polyurethane foam infused midsole 5 is connected to the upper side of the transparent polyurethane outsole 11 and the air cushion component 4.

[0034] The outsole assembly 1 also includes X-shaped grooves 18. X-shaped grooves 18 are evenly spaced along the top edge of the transparent polyurethane outsole 11, and are located on the bottom inner side of the upper connecting assembly 2. When foamed polyurethane is poured into the transparent polyurethane outsole 11 to form the foamed polyurethane insole midsole 5, the X-shaped grooves 18 can increase the contact area between the foamed polyurethane insole midsole 5 and the transparent polyurethane outsole 11, improving the connection strength between them. During the pouring of foamed polyurethane into the transparent polyurethane outsole 11, the upper connecting assembly 2 also serves to limit the movement of the foamed polyurethane, helping to maintain the shape of the foamed polyurethane insole midsole 5.

[0035] The outsole assembly 1 also includes protruding posts 19, which are evenly distributed on the front end of the top face of the transparent polyurethane outsole 11. The protruding posts 19 can also increase the contact area between the foamed polyurethane insole 5 and the transparent polyurethane outsole 11, and enhance the connection strength between the front end of the foamed polyurethane insole 5 and the transparent polyurethane outsole 11.

[0036] The upper connecting component 2 includes an upper connecting ring 21, a raised edge 22, an adhesive annular groove 23, and an upper fixing annular groove 24. The top edge of the transparent polyurethane outsole 11 is integrally formed and connected to the bottom end of the upper connecting ring 21. The upper connecting ring 21 has an upper fixing annular groove 24 on its inner side. The top inner side of the upper connecting ring 21 is integrally formed and connected to the raised edge 22. The inner side of the raised edge 22 has an adhesive annular groove 23. When installing the upper, the bottom edge of the upper is inserted into the upper fixing annular groove 24. Adhesive is applied between the upper connecting ring 21 and the upper. The adhesive annular groove 23 on the upper fixing annular groove 24 and the raised edge 22 can better accommodate the adhesive, allowing more adhesive between the upper connecting ring 21 and the upper, thus improving the bonding strength between the upper connecting ring 21 and the upper.

[0037] The upper connecting component 2 also includes a midsole reinforcement groove 25. The bottom inner side of the upper connecting ring 21 has equidistantly spaced midsole reinforcement grooves 25. These grooves connect to the side of the polyurethane foam-infused midsole 5, and the top surface of the polyurethane foam-infused midsole 5 is lower than the bottom surface of the upper fixing annular groove 24. During polyurethane foam infusion, the polyurethane foam enters the midsole reinforcement groove 25, increasing the contact area between the upper connecting ring 21 and the polyurethane foam-infused midsole 5, thus making the connection between the polyurethane foam-infused midsole 5 and the bottom inner side of the upper connecting ring 21 more stable.

[0038] In use, transparent polyurethane material is first poured into a mold to form a transparent polyurethane outsole 11. The poured transparent polyurethane outsole 11 has water guiding grooves 12, anti-slip raised strips 13, air cushion limiting grooves 17, and friction patterns. The anti-slip raised strips 13 and friction patterns both increase ground friction, thus preventing slipping. When wet, water is discharged through two adjacent anti-slip raised strips 13 and water guiding grooves 12, which can prevent water from accumulating between the sole and the ground on wet surfaces, thus avoiding reduced friction. The upper connecting component 2 is used to stably connect with the upper using adhesive. The air cushion component 4 can improve the cushioning effect of the sole, making it suitable for sports. After the outsole component 1 is formed, the air cushion component 4 is placed in the air cushion limiting groove 17, and then polyurethane foam is injected to form the polyurethane foam injection midsole 5. The polyurethane foam injection midsole 5 seals the upper side of the transparent polyurethane outsole 11 and the air cushion component 4. The polyurethane foam injection midsole 5 has a low density, making the shoes more comfortable to wear.

[0039] Example 2, please refer to Figures 1 to 7 This utility model provides a technical solution: a transparent polyurethane shoe sole. This embodiment is a further explanation of the structure of Embodiment 1.

[0040] The air cushion assembly 4 includes an upper air cushion layer 41, a lower air cushion layer 42, and reinforcing anchor points 43. The edges of the upper air cushion layer 41 and the lower air cushion layer 42 are connected to form the main body of the air cushion, which is filled with air. The upper air cushion layer 41 and the lower air cushion layer 42 are connected by evenly distributed reinforcing anchor points 43. The main body of the air cushion, consisting of the upper air cushion layer 41 and the lower air cushion layer 42, can absorb shocks. The reinforcing anchor points 43 can enhance the connection strength between the upper air cushion layer 41 and the lower air cushion layer 42, thereby improving the overall robustness of the air cushion assembly 4. The air cushion assembly 4 can be made of rubber or other suitable materials.

[0041] Example 3, please refer to Figures 1 to 7 This utility model provides a technical solution: a transparent polyurethane shoe sole. This embodiment is structurally similar to Embodiment 2, with the difference being:

[0042] It also includes a deformation cavity assembly 3, which includes a strip groove 31 and a cavity sealing pad 33. Two strip grooves 31 are provided on the upper surface of the transparent polyurethane outsole 11 at the position in front of the air cushion limiting groove 17, and a cavity sealing pad 33 is provided on the upper surface of the transparent polyurethane outsole 11 at the position corresponding to the two strip grooves 31.

[0043] The deformable cavity assembly 3 also includes positioning grooves 32 and positioning posts 34. Two positioning grooves 32 are respectively opened on the upper surface of the transparent polyurethane base 11 between the two strip grooves 31. Two positioning posts 34 are respectively set on the bottom of the cavity sealing pad 33 corresponding to the positions of the two positioning grooves 32. The positioning grooves 32 and positioning posts 34 are used to position the cavity sealing pad 33, which facilitates the installation of the cavity sealing pad 33 during processing. The cavity sealing pad 33 can be made of a suitable material, such as foamed polyurethane material.

[0044] The cavity sealing pad 33 can prevent polyurethane foam from entering the strip groove 31 during polyurethane foam injection. After polyurethane foam injection, there is no polyurethane foam in the two strip grooves 31. The formed sole creates a cavity between the ball of the foot and the toe, which facilitates the bending of the sole and makes walking more comfortable.
