A type of durable slipper

Abstract

This utility model relates to a wear-resistant slipper, comprising a slipper shell, the upper part of which is the upper, and a sole attached to the bottom of the upper. The bottom of the sole is a wear-resistant layer, with anti-slip protrusions evenly distributed on the bottom of the wear-resistant layer, and anti-slip grooves evenly distributed on the bottom of the wear-resistant layer. Anti-slip studs are evenly distributed on the outer periphery of the lower surface of the wear-resistant layer. The added wear-resistant layer and the evenly distributed anti-slip protrusions on the bottom increase the frictional resistance of the contact surface when walking; the evenly distributed anti-slip grooves can quickly drain water or oil between the sole and the ground, preventing slippage caused by liquid film; the evenly distributed anti-slip studs on the outer periphery of the lower surface can penetrate deep into the ground to form a mechanical engagement when in contact with soft ground, further enhancing the anti-slip effect. The three structures work together through different mechanisms to ensure that the sole maintains stable grip under various ground conditions.

Description

Technical Field

[0001] This utility model relates to the field of slippers, specifically to a wear-resistant slipper. Background Technology

[0002] Slippers are lightweight footwear with an open heel and a toe box. They are typically flat and laceless, and are often made of materials such as leather, plastic, or fabric, with comfort and convenience as their core features. Their design aims to liberate the feet, reducing the restrictive feeling of traditional footwear, while also considering leisure and practicality, making them suitable for home, beach, and bathroom settings.

[0003] Existing slippers have insufficient friction resistance when in contact with the ground, making them prone to slipping. When walking on wet or oily surfaces, the liquid between the sole and the ground is difficult to drain quickly, and the liquid film can cause further slipping. When walking on soft surfaces, the sole cannot effectively penetrate the ground to form a stable grip. In addition, the sole is prone to wear and tear, and its thickness is constantly reduced, resulting in a short overall lifespan. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a wear-resistant slipper that increases the frictional resistance of the contact surface, avoids slippage caused by liquid film, and slows down the thinning of the sole. This solves the technical problems of existing technologies, such as easy slippage, difficulty in quickly draining liquid between the sole and the ground when walking on wet or oily surfaces, leading to further slippage due to the liquid film, inability of the sole to effectively penetrate the ground to form a stable grip when walking on soft ground, and easy wear and tear on the sole, resulting in a short overall service life.

[0005] The objective of this utility model is achieved through the following means:

[0006] A wear-resistant slipper includes a slipper shell, the upper part of which is the upper, and the bottom of which is the sole. The bottom of the sole is a wear-resistant layer, and the bottom of the wear-resistant layer is evenly provided with anti-slip protrusions and anti-slip patterns. The lower surface of the wear-resistant layer is evenly provided with anti-slip studs.

[0007] Furthermore, the upper surface of the shoe upper is provided with breathable patterns in a serpentine design. Through a dynamic airflow guiding structure, the heat exchange efficiency between the foot and the air is significantly improved. At the same time, the serpentine design can effectively disperse local stress and prevent the patterns from breaking due to long-term use. Micro-ventilation holes are provided at the adjacent bends of the serpentine pattern. These micro-ventilation holes are connected to the honeycomb-shaped air holes inside the middle layer, which can extend the airflow time through the serpentine path and achieve continuous ventilation by utilizing the air storage function of the honeycomb-shaped air holes.

[0008] Furthermore, the upper has a middle layer in the middle, and an inner layer is connected to the lower part of the middle layer. The inner layer is connected to the sole. The middle layer is made of high-density fabric and elastic fiber composite weaving to form a three-dimensional support skeleton. The inner layer is made of skin-friendly and antibacterial material and is seamlessly bonded to the middle layer through a hot-pressing process to achieve a dual improvement in comfort and functionality. The inner layer has several radially distributed reinforcing ribs integrally formed on the side facing the sole. The reinforcing ribs are embedded in the base layer and abut against the reinforcement layer. The radial structure can evenly distribute the foot pressure to the reinforcement layer and improve the overall deformation resistance of the sole.

[0009] Furthermore, the upper part of the sole is a base layer, and the wear-resistant layer is installed at the bottom of the base layer. The base layer is connected to the inner layer. The base layer is formed by polyurethane rubber injection molding, which can effectively absorb the impact of walking. The wear-resistant layer adopts a dual-hardness polyurethane composite process, which takes into account the needs of wear resistance and shock absorption of the outer layer. Moreover, the connection surfaces of the base layer and the inner layer adopt a serrated interlocking structure. The gaps of the serrated interlocking structure are filled with an elastic adhesive layer, which can enhance the connection strength through mechanical interlocking and buffer the relative displacement between the two through the elastic adhesive layer.

[0010] Furthermore, the bottom of the wear-resistant layer and the corresponding position of the anti-slip nail are each provided with an installation groove. The anti-slip nails are all installed inside the installation grooves. The anti-slip nails adopt a multi-faceted pyramidal three-dimensional structure, and their surfaces are treated with laser etching to form a microscopic suction cup effect, which can generate molecular-level adsorption force on wet and slippery surfaces. The top of the anti-slip nail is connected to the bottom of the installation groove through an elastic buffer. The outer wall of the anti-slip nail is wrapped with an elastic wear-resistant sleeve. The outer surface of the elastic wear-resistant sleeve is provided with a spiral ridge. The elastic buffer allows the anti-slip nail to adapt and expand when in contact with the ground. The spiral ridge can enhance the frictional resistance with the ground. At the same time, the elastic wear-resistant sleeve can reduce the direct wear between the anti-slip nail and the installation groove.

[0011] Furthermore, the forefoot and heel areas of the base layer are embedded with reinforcement layers, and the connection between the upper and the sole is fitted with a sealing layer. The reinforcement layer is made of a blend of three-dimensional woven carbon fiber and thermoplastic polyurethane, which is bonded to the base layer at the molecular level through in-mold injection molding. The forefoot area is reinforced with lateral support, and the heel area is enhanced with longitudinal stability, enabling precise force transmission during dynamic walking. The sealing layer is made of liquid silicone through secondary injection molding, and the seams are sealed. At the same time, stress is released through an elastic deformation mechanism to avoid cracking problems caused by traditional adhesive bonding processes.

[0012] Furthermore, the inner side of the sealing layer is uniformly provided with a number of elastic support blocks along the length direction. The cross-section of the elastic support block is an isosceles trapezoid, and a buffer cavity is formed between adjacent elastic support blocks. The buffer cavity is filled with breathable cotton wool. The isosceles trapezoidal structure can improve the sealing layer's resistance to compression. The combination of the buffer cavity and the breathable cotton wool can achieve moisture drainage while ensuring the sealing effect.

[0013] The beneficial effects of this utility model are:

[0014] The added abrasion-resistant layer and the evenly distributed anti-slip protrusions on the bottom increase the frictional resistance of the contact surface when walking; the evenly spaced anti-slip grooves quickly drain water or oil from between the sole and the ground, preventing slippage caused by liquid film; the anti-slip studs evenly distributed on the outer perimeter of the lower surface penetrate deep into the ground to form a mechanical engagement when in contact with soft surfaces, further enhancing the anti-slip effect. These three structures work together through different mechanisms to ensure the sole maintains stable grip under various surface conditions, while the abrasion-resistant layer directly withstands wear, effectively slowing down the thinning of the sole and extending its overall lifespan.

[0022] The slipper shell 1 has an upper 2 on the upper part and a sole 3 on the bottom. The bottom of the sole 3 has a wear-resistant layer 32. The bottom of the wear-resistant layer 32 is evenly distributed with anti-slip protrusions 33, which can increase the contact friction with the ground and play an anti-slip role. At the same time, anti-slip patterns 34 are evenly distributed to further increase the coefficient of friction with the ground and improve the anti-slip performance. In addition, the outer periphery of the lower surface of the wear-resistant layer 32 is evenly distributed with anti-slip studs 35. During walking, the anti-slip studs 35 can embed into the tiny bumps and depressions of the ground to enhance grip. The combined effect of multiple anti-slip structures effectively improves the overall anti-slip effect of the slipper, and the wear-resistant layer 32 can enhance the wear resistance of the sole 3 and extend the service life of the slipper.

[0023] The upper surface of the shoe upper 2 has a breathable pattern 21 with a serpentine design. Through the dynamic airflow guiding structure, the heat exchange efficiency between the foot and the air is significantly improved. At the same time, the serpentine design can effectively disperse local stress and prevent the pattern from breaking due to long-term use.

The inner layer 23 is made of skin-friendly antibacterial material and is seamlessly bonded to the middle layer 22 through hot pressing process to achieve a dual improvement in comfort and functionality. The inner layer 23 has several radially distributed reinforcing ribs integrally formed on the side facing the sole. The reinforcing ribs are embedded in the base layer 31 and abut against the reinforcement layer 37.

[0025] The upper part of the sole 3 is the base layer 31, and the wear-resistant layer 32 is installed at the bottom of the base layer 31. The base layer 31 is connected to the inner layer 23. The base layer 31 is formed by injection molding of polyurethane rubber, which can effectively absorb the impact of walking. The wear-resistant layer 32 adopts a dual-hardness polyurethane composite process to take into account the needs of wear resistance and shock absorption of the outer layer. The connection surfaces of the base layer 31 and the inner layer 23 both adopt a serrated interlocking structure. The gaps of the serrated interlocking structure are filled with an elastic adhesive layer, which can enhance the connection strength through mechanical interlocking and buffer the relative displacement between the two through the elastic adhesive layer.

[0026] The bottom of the wear-resistant layer 32 and the corresponding position of the anti-slip stud 35 are both provided with mounting grooves 36. The anti-slip studs 35 are all installed inside the mounting grooves 36. The anti-slip studs 35 adopt a multi-faceted pyramidal three-dimensional structure. Their surfaces are treated with laser etching to form a microscopic suction cup effect, which can generate molecular-level adsorption force on wet and slippery surfaces. The top of the anti-slip studs 35 is connected to the bottom of the mounting groove 36 through an elastic buffer. The outer wall of the anti-slip studs 35 is wrapped with an elastic wear-resistant sleeve. The outer surface of the elastic wear-resistant sleeve is provided with spiral ridges. The elastic buffer allows the anti-slip studs to adapt and expand when in contact with the ground. The spiral ridges can enhance the frictional resistance with the ground. At the same time, the elastic wear-resistant sleeve can reduce the direct wear between the anti-slip studs 35 and the mounting grooves 36.

[0027] The forefoot and heel areas of the base layer 31 are embedded with reinforcing layers 37, and sealing layers 4 are installed at the connection between the upper 2 and the sole 3. The reinforcing layer 37 is made of a blend of three-dimensional woven carbon fiber and thermoplastic polyurethane, which is bonded to the base layer 31 at the molecular level through in-mold injection molding. The forefoot area is reinforced with lateral support, and the heel area is enhanced with longitudinal stability, so as to achieve precise force transmission during dynamic walking.

The cross-section of the elastic support block is an isosceles trapezoid, and a buffer cavity is formed between adjacent elastic support blocks. The buffer cavity is filled with breathable cotton wool. The isosceles trapezoidal structure can improve the compression resistance of the sealing layer. The combination of the buffer cavity and the breathable cotton wool can achieve moisture venting while ensuring the sealing effect.

[0029] In this embodiment, the upper 2 features a serpentine breathable pattern 21, which significantly improves the heat exchange efficiency between the foot and the air through a dynamic airflow guiding structure. The serpentine design also disperses localized stress, preventing the pattern from breaking. The middle layer 22 uses a high-density fabric and elastic fiber composite weaving to form a three-dimensional support frame. The inner layer 23 uses skin-friendly antibacterial materials and is seamlessly bonded to the middle layer 22 via a hot-pressing process, achieving a dual improvement in comfort and functionality. The base layer 31 of the sole 3 is made of polyurethane rubber injection molding, effectively absorbing the impact of walking. The reinforcing layers 37 embedded in the forefoot and heel areas use three-dimensional woven carbon fiber. The material is blended with thermoplastic polyurethane to enhance lateral support in the forefoot and longitudinal stability in the heel for precise force transmission. The wear-resistant layer 32 is installed at the bottom of the base layer 31 using a dual-hardness polyurethane composite process.
