Description

Technical Field

[0001] This application relates to the technical field of footwear, and more specifically, to a high-strength, resilient slipper. Background Technology

[0002] Traditional slippers typically consist of a sole and an upper. The sole is often made of materials such as EVA (ethylene-vinyl acetate copolymer), rubber, or foamed plastic. While these materials are lightweight and flexible, their resilience and compressive strength are significantly insufficient. After prolonged use, the sole is prone to plastic deformation due to repeated pressure, leading to decreased support and increased foot fatigue. They are particularly unsuitable for comfort during exercise recovery or prolonged standing. Utility Model Content

[0003] To address the significant deficiencies in resilience and compressive strength of traditional slippers, this application provides a high-strength, resilient slipper.

[0004] A high-strength rebound slipper includes a sole, an upper, an insole, and a carbon fiber elastic sheet. The sole and the upper are integrally formed from EVA material, and the insole is also made of EVA material. The carbon fiber elastic sheet and the insole are sequentially bonded to the top surface of the sole.

[0005] Preferably, the carbon fiber elastic sheet has a thickness of 1-3 mm and extends to the stress-bearing areas of the forefoot and heel of the sole.

[0006] Preferably, the sole has a display hole extending through its own thickness, and the display hole is aligned with the carbon fiber elastic sheet.

[0007] Preferably, the top surface of the sole has a first groove recessed around the display hole, and a baffle is embedded in the first groove. The baffle is made of transparent material. The top surface of the sole has a second groove recessed around the first groove, and a hard pressure plate is embedded in the second groove. The hard pressure plate is glued to the sole and presses against the edge of the baffle.

[0008] Preferably, the bottom surface of the baffle is further provided with a protrusion that matches the outline and size of the display hole, and the protrusion passes through the display hole.

[0009] Preferably, the top surface of the insole is evenly distributed with a plurality of first anti-slip stripes.

[0010] Preferably, the bottom surface of the shoe sole is evenly distributed with a plurality of second anti-slip stripes.

[0011] The beneficial technical effects of this application are as follows: Carbon fiber elastic sheets have the characteristics of high elastic modulus, high strength, high resilience and lightweight. By pioneering the composite of carbon fiber elastic sheets with EVA material soles and insoles, the high modulus material mechanically reinforces and disperses pressure on the low modulus matrix, giving the slippers high compressive strength. This helps the slippers maintain stable support after long-term use, meeting the comfort needs of scenarios such as sports recovery and long-term standing. Attached Figure Description

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1A high-strength rebound slipper includes a sole 1, an upper 2, an insole 3, and a carbon fiber elastic sheet 4. The sole 1 and upper 2 are integrally injection molded from EVA material to ensure seamless connection and lightweight. The upper 2 includes a perimeter 21 surrounding the top edge of the sole 1 and a wrapping and limiting part 22 that spans the width of the sole 1. The wrapping and limiting part 22 wraps around the periphery and top of the foot, allowing the user to drag the entire slipper while walking. The carbon fiber elastic sheet 4 and the insole 3 are sequentially bonded to the top surface of the sole 1, and the insole 3 is also bonded and fixed to the perimeter of the perimeter 21 to increase the connection strength. The insole 3 is also made of EVA. The material, and the thickness of the carbon fiber elastic sheet 4 is 1-3mm, preferably 2mm, and it extends to the forefoot and heel stress areas of the sole 1. The carbon fiber elastic sheet 4 is made of carbon fiber prepreg, which has the characteristics of high elastic modulus, high strength, high resilience and lightweight. By innovatively combining the carbon fiber elastic sheet 4 with the EVA material sole 1 and insole 3, the high modulus material mechanically reinforces and disperses the pressure of the low modulus matrix, so that the slippers have high compressive strength, which is conducive to maintaining stable support after long-term use of the slippers, and meeting the comfort needs of scenarios such as sports recovery and long-term standing.

[0018] Reference Figure 1 and Figure 2 Furthermore, the sole 1 has a display hole 11 that extends through its own thickness. The display hole 11 is aligned with the carbon fiber elastic sheet 4. The display hole 11 allows consumers to directly observe the presence of the carbon fiber elastic sheet 4 from the bottom surface of the sole 1, realizing the visual transmission of the product's technological advantages and enhancing brand credibility and market competitiveness.

[0019] Reference Figure 1 Furthermore, a first groove 12 is recessed around the display hole 11 on the top surface of the sole 1. A baffle 5 is embedded in the first groove 12. The baffle 5 is made of transparent material, which can be acrylic or transparent silicone, preferably acrylic. A second groove 13 is also recessed around the first groove 12 on the top surface of the sole 1. A hard pressure plate 6 is embedded in the second groove 13. The hard pressure plate 6 is glued to the sole 1 and presses against the edge of the baffle 5. The top surface of the hard pressure plate 6 is flush with the top surface of the sole 1. The baffle 5 allows the carbon fiber elastic sheet to be visible while preventing hard objects such as stones from impacting the carbon fiber elastic sheet 4 through the display hole 11. This helps to maintain the stability of the connection between the carbon fiber elastic sheet 4 and the sole 1 and reduces the wear of the carbon fiber elastic sheet 4. The baffle 5 is fixed by the hard pressure plate 6.

[0020] Reference Figure 1 and Figure 3Furthermore, the bottom surface of the baffle 5 is also provided with a protrusion 51 that matches the outline and size of the display hole 11. The protrusion 51 is inserted into the display hole 11. The size and outline of the protrusion 51 are matched with those of the display hole 11, which simplifies the assembly and positioning process, reduces production errors, and the protrusion 51 helps to reduce the number of stones stuck in the display hole 11.

[0021] Reference Figure 1 Furthermore, the top surface of the insole 3 is evenly distributed with several first anti-slip stripes 31. These first anti-slip stripes 31 increase the friction between the insole 3 and the human foot, reduce the sliding between the foot and the insole 3, and lower the risk of slipping.

[0022] Reference Figure 2 Furthermore, the sole 1 is evenly distributed with several second anti-slip stripes 14, which increase the friction between the sole 1 and the ground and further reduce the risk of slipping.
