Abstract
Description
Technical Field
[0001] This application relates to the technical field of shoe covers, and more specifically, to a semi-enclosed protective shoe cover. Background Technology
[0002] In specialized work environments such as food processing plants, breweries, and chemical workshops, liquid residues, such as wine stains, oil stains, cleaning agents, and sharp metal edges, are often present on the ground. Workers must simultaneously meet the core requirements of slip resistance and foot protection.
[0003] Currently, the mainstream protective shoe covers on the market are mainly of a full-coverage structure. These shoe covers are usually made of materials such as plastic film, non-woven fabric, and coated fabric, and are designed to completely wrap around the sole, upper, and collar of the user's original shoe, up to the ankle or calf, and are secured with Velcro, elastic bands, zippers, etc. Shoe covers made of plastic film, non-woven fabric, or thin-layer coated fabric, using the above design, have low material strength and poor tear resistance, making them difficult to withstand the impact of heavy objects. They also offer poor slip resistance on surfaces mixed with oil or water, and because they completely cover the shoe, they have poor breathability. Utility Model Content
[0004] To address the issue that mainstream protective shoe covers are insufficient in providing both slip resistance and foot impact protection, this application provides a semi-enclosed protective shoe cover.
[0005] A semi-enclosed protective shoe cover includes a base integrally molded from a highly elastic foam material. The base includes the bottom of the forefoot portion of the sole and a U-shaped edging extending upward from the front edge of the bottom and both sides, a left wing and a right wing extending symmetrically backward and upward from the rear end of the edging. A heel buckle assembly is provided between the ends of the left wing and the right wing. An upper fixing strap assembly is provided between the left wing and the edging near the edging, and an anti-slip bump array is provided on the lower surface of the bottom.
[0006] Preferably, the front end of the edging is concave arc-shaped to cover the top edge of the toe.
[0007] Preferably, the anti-slip bump array is composed of uniformly arranged bumps, the height of the bumps is 1-3mm, and a flow guide groove is formed between adjacent bumps, the width of the flow guide groove is 2-3mm.
[0008] Preferably, the top surface of the protrusion is recessed with a cross-shaped groove penetrating its side, and the depth of the cross-shaped groove is 1-2 mm.
[0009] Preferably, the heel strap assembly includes a transverse groove disposed on the inner side of the left wing piece, a vertical narrow hole disposed on the right wing piece, and a nylon webbing with its first end fixed to the transverse groove. The nylon webbing passes through the vertical narrow hole and is folded inward. The portion of the nylon webbing between the left and right wing pieces is provided with a male Velcro fastener, and the folded section of the nylon webbing is provided with a female Velcro fastener.
[0010] Preferably, the shoe upper fixing strap assembly includes a left ear extending upward from the left wing near the edge, a vertical groove disposed on the inner side of the left ear, a right ear extending upward from the right wing near the edge, a transverse narrow hole disposed on the right ear, and an elastic silicone strip whose first section is fixed to the vertical groove. One end of the elastic silicone strip passes through the transverse narrow hole and the end is provided with an abutment for abutting against the outer side of the right ear. The length and width dimensions of the abutment are both larger than the length and width dimensions of the transverse narrow hole.
[0011] Preferably, the left and right wing pieces form an angle of 55-65° with the horizontal plane.
[0012] The beneficial technical effects of this application are as follows: The substrate is integrally molded with high-elasticity foam material. Compared with traditional plastic film, non-woven fabric or thin-coated fabric, high-elasticity foam material has excellent impact resistance, cushioning energy absorption and pressure resistance, which can effectively buffer the impact force generated when colliding with heavy objects and protect the feet; the semi-enclosed design makes the shoe cover highly breathable and prevents the feet from getting stuffy; and the bottom surface is provided with an array of anti-slip bumps, which can significantly increase the contact friction coefficient between the sole and the ground, especially on mixed surfaces with slippery liquids such as wine stains, oil stains, and detergents.

[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 1 A semi-enclosed protective shoe cover includes a base, which is integrally formed from a high-elasticity foam material using a mold. Specifically, the high-elasticity foam material is a polyurethane foam with a density of 0.15-0.25 g / cm³. The base includes a bottom 1, a edging 2, a left wing piece 3, and a right wing piece 4. The bottom 1 covers the forefoot area of the sole and has a thickness of 8-12 mm, preferably 10 mm, providing basic support. The edging 2 extends upward from the front edge and sides of the bottom 1 in a U-shape, with a height of 30-40 mm, preferably 40 mm, covering the toe and the edges of the upper on both sides. The left wing piece 3 and the right wing piece 4 are symmetrically formed at the rear end of the edging 2, extending backward and upward at a 60° angle to the horizontal plane, covering the ankle area. A heel buckle assembly 5 is provided between the ends of the left wing piece 3 and the right wing piece 4. A shoe upper fixing strap assembly 6 is provided between the near edge 2 and the right wing piece 4 near the near edge 2. The shoe cover is fixed to the shoe by the heel buckle assembly 5 and the shoe upper fixing strap assembly. The lower surface of the bottom 1 is provided with an array of anti-slip protrusions 71 to improve the grip on wet and slippery surfaces. In the above structure, a high-elasticity foam material is used as the integrally molded base. Compared with traditional plastic film, non-woven fabric or thin-coated fabric, high-elasticity foam material has excellent impact resistance, cushioning energy absorption and pressure resistance, and can effectively buffer the impact force generated when colliding with heavy objects to protect the feet. The semi-enclosed design makes the shoe cover highly breathable and prevents the feet from getting stuffy. In addition, the anti-slip protrusions 71 array 7 on the lower surface of the bottom 1 can significantly increase the contact friction coefficient between the sole and the ground, especially on mixed surfaces with slippery liquids such as wine stains, oil stains, and detergents.
[0018] Reference Figure 1 Furthermore, the front end of the edging 2 is designed with a concave arc shape to cover the top edge of the toe, which makes the shoe cover less likely to detach from the shoe and provides better protection for the toes.
[0019] Reference Figure 2 Furthermore, the anti-slip bump array 71 is composed of evenly arranged bumps 71 with a height of 3mm. A flow guide groove 72 is formed between adjacent bumps 71 with a width of 2mm. The anti-slip array formed by the bumps 71 enhances the friction of the bottom 1 and increases grip. The flow guide groove 72 realizes the function of draining water and oil.
[0020] Reference Figure 2Furthermore, the top surface of the protrusion 71 is recessed with a cross groove 73 that runs through its four sides. The depth of the cross groove 73 is 1mm. The cross groove 73 reduces the volume of the top of the protrusion 71, making it easier for the protrusion 71 to break the liquid film and making it more slip-resistant in wet environments.
[0021] Reference Figure 1 and Figure 2 Furthermore, the heel strap assembly 5 includes a transverse groove 51 located inside the left wing piece 3, a vertical narrow hole 52 located on the right wing piece 4, and a nylon webbing 53 with its first end fixed to the transverse groove 51. The first section of the nylon webbing 53 is fixed to the left wing piece 3 by adhesive. The nylon webbing 53 passes through the vertical narrow hole 52 and folds inward. The portion of the nylon webbing 53 between the left wing piece 3 and the right wing piece 4 is provided with a male Velcro fastener 54, and the folded section of the nylon webbing 53 is provided with a female Velcro fastener 55. By pressing the nylon webbing 53 against the heel, the shoe cover is secured to the shoe. The tightness of the nylon webbing 53 against the heel is adjustable by the fastening of the male and female Velcro fasteners, making the shoe cover more adaptable.
[0022] Reference Figure 1 and Figure 2 Furthermore, the shoe upper fixing strap assembly includes a left ear portion 61 extending upward from the left wing piece 3 near the edge 2, a vertical groove 62 disposed on the inner side of the left ear portion 61, a right ear portion 63 extending upward from the right wing piece 4 near the edge 2, a transverse narrow hole 64 disposed on the right ear portion 63, and an elastic silicone strip 65 whose first section is fixed to the vertical groove 62. The first end of the elastic silicone strip 65 is glued to the left ear portion 61. One end of the elastic silicone strip 65 passes through the transverse narrow hole 64 and is provided with an abutment member 66 for abutting against the outer side of the right ear portion 63. The length and width of the abutment member 66 are both larger than the length and width of the transverse narrow hole 64. By pressing the elastic silicone strip 65 against the top of the shoe upper, the shoe is prevented from detaching from the top of the shoe cover, resulting in a better fixing effect between the shoe cover and the shoe. At the same time, the elasticity of the elastic silicone strip 65 can be used to adapt to different shoe upper heights, making the shoe cover more adaptable.
[0023] The implementation principle of this application for a semi-enclosed protective shoe cover is as follows: align the bottom 1 of the shoe cover with the forefoot of the shoe, wrap the U-shaped edging 2 around the toe of the shoe, and cross the elastic silicone strip 65 across the shoe surface. Pull the left and right wing pieces 4 towards the sides of the shoe so that the left and right wing pieces 3 and 4 fit the shoe. Then, wrap the nylon webbing 53 of the heel buckle around to the back of the heel, pass it through the narrow hole, and then attach the Velcro to complete the shoe cover. This shoe cover has good breathability, anti-slip, and anti-collision functions.
[0024] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
