Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a lightweight high-rebound sole. Background Art

[0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it refers only to the outsole. The common characteristics of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to adapt to the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it must cooperate with the midsole to have a braking effect when changing feet while walking to avoid slipping and easy to stop.

[0003] For example, the authorization announcement number "CN218008426U" is named a lightweight high-rebound sole. Although the rebound effect is guaranteed by arranging a rebound tube in the shock-absorbing rebound hole and a spring in the rebound tube, and at the same time its pressure-bearing capacity is greatly improved, and it is not easy to collapse and deform, the existing lightweight high-rebound soles, due to the large number of rebound tubes set up inside the soles to increase the rebound performance, although the rebound pressure-bearing capacity is improved, too many rebound tubes will increase the weight of the sole itself, and the sole needs to be adhered and fixed to the upper surface. In this way, when the shoes with soles with too many rebound tubes are worn on people's feet, it will make it more difficult to lift the feet, and the rebound tubes are fully distributed in most corners of the soles. The rebound tubes at the edge where the soles are stepped on lack a fulcrum and will be idle. Therefore, the use effect of the existing lightweight high-rebound soles is not ideal. Utility Model Content

[0004] The utility model aims to solve the problem that the use effect of lightweight high-rebound soles is poor, and proposes a lightweight high-rebound sole.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] See also Figure 1-6 A lightweight high-rebound sole comprises a sole body 1, a sole side 2 and a sole texture 3. A first bottom surface layer 7 is fixedly installed on both sides of the inner side of the sole body 1. A plurality of rebound springs 8 are fixedly installed on the inner side of the first bottom surface layer 7. The rebound spring 8 is made of a plurality of rubber springs with high toughness elastic coefficients. The rebound spring 8 is evenly distributed on the inner side of the first bottom surface layer 7. The rebound spring 8 can withstand a small amount of pressure and has a relatively low weight. A second bottom surface layer 14 is fixedly installed in the middle of the sole body 1. A plurality of positioning tubes 10 are fixedly installed on the inner side of the second bottom surface layer 14. A plurality of extrusion columns 12 are movably connected to the inner side of the plurality of positioning tubes 10. After the extrusion columns 12 are subjected to pressure from above, the extrusion columns 12 will slide downward along the inner side of the positioning tubes 10. The extrusion columns 12 will compress the elastic airbag 11 to shrink. The elastic airbag 11 adopts a rubber ball structure with relatively large elastic force of internally filled gas.

[0021] The resilience of the sole is improved by compressing the elastic airbag 11. The resilience value of the elastic airbag 11 is higher than the resilience value of the rebound spring 8, but the weight of the elastic airbag 11 itself is relatively large. Multiple elastic airbags 11 are fixedly installed on the inner sides of multiple positioning tubes 10. A bonding block 13 is fixedly installed on the top of multiple positioning tubes 10. Multiple limiting rods 9 are fixedly connected to the outer sides of multiple positioning tubes 10. The limiting rods 9 can play a role in positioning and guiding the sliding extrusion column 12. A connecting layer 5 is fixedly installed on the inner side of the sole body 1. The connecting layer 5 is made of rubber material. The connecting layer 5 is used to directly adhere to the bottom surface of the shoe. A reinforcement layer 6 is provided below the connecting layer 5. The reinforcement layer 6 is made of a strong resin material with good puncture resistance. The reinforcement layer 6 can improve the firmness of the connecting layer 5 and also improve the puncture resistance of the bottom of the sole body 1. The bottom end of the reinforcement layer 6 is fixedly connected to the top of the multiple bonding blocks 13, and the lower end of the reinforcement layer 6 is fixedly connected to the tops of the multiple rebound springs 8 on both sides.

[0022] The rebound spring 8 is made of a plurality of rubber springs with high toughness elastic coefficients, and the rebound spring 8 is evenly distributed on the inner side of the first bottom surface layer 7. The rebound spring 8 can withstand a small amount of pressure and has a relatively low weight. After the extrusion column 12 is subjected to pressure from above, the extrusion column 12 will slide downward along the inner side of the positioning tube 10, and the extrusion column 12 will compress the elastic airbag 11 to shrink. The elastic airbag 11 adopts a rubber ball structure with relatively large elasticity of the internal filling gas. The resilience of the sole is improved by compressing the elastic airbag 11. The resilience value of the elastic airbag 11 is higher than the resilience value of the rebound spring 8, but the weight of the elastic airbag 11 itself is relatively large. The springs with light weight and poor resilience are placed on both sides of the sole, while the extrusion column 12 with large weight and strong resilience is placed in the middle part of the sole. Therefore, the positions with fewer stress points are assisted by unimportant rebound structures, and a stronger rebound structure is set up at the main stress position, which can reduce the mass and investment without weakening the resilience, thereby improving the use effect of the lightweight and high-rebound sole.

The grid bars 4 are staggered with a plurality of sole grid structures to provide better support for the foot, reduce the impact of the stress points and achieve a better buffering effect.

The decorative strip 17 can be a reflective strip of various materials or colors. The decorative strip 17 is attached to the outer wall of the side edge 2 of the sole through the adhesive layer 16. The decorative strip 17 can improve the visual effect and eye-catching effect. The plurality of decorative strips 17 are arranged parallel to each other. A waterproof layer 15 is fixedly installed on the inner side of the sole body 1. The waterproof layer 15 is made of polyvinyl chloride material. The waterproof layer 15 is arranged inside the sole body 1 and the side edge 2 of the sole, which can reduce the occurrence of ground water seeping into the sole. The two sides of the waterproof layer 15 are fixedly connected to the inside of the side edge 2 of the sole. Two sole textures 3 are fixedly installed on the bottom end of the sole body 1. The sole texture 3 can be of various styles to increase the anti-slip property and grip of the bottom surface of the sole body 1.

The extrusion column 12 will compress the elastic airbag 11 to shrink. The elastic airbag 11 adopts a rubber ball structure with relatively large elastic force of the internal filling gas.

[0029] The elastic airbag 11 is compressed to improve the rebound ability of the sole. The rebound value of the elastic airbag 11 is higher than the rebound value of the rebound spring 8. However, the elastic airbag 11 itself is relatively heavy. The limit rod 9 can play a role in positioning and guiding the sliding extrusion column 12. The connecting layer 5 is made of a rubber material and is directly bonded to the bottom surface of the shoe. A reinforcement layer 6 is provided below the connecting layer 5.
