Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe cover technology, and in particular to a multifunctional shoe cover. Background Technology
[0002] Shoe covers, as protective gear placed on the outside of shoes, can prevent shoes from being damaged by dirt and water stains in rainy, snowy, or muddy environments, thus extending the lifespan of shoes. However, the common way to use shoe covers in the current technology is to completely cover and wrap the shoes to achieve protection. But this type of shoe cover is not convenient to put on and take off, and its application scenarios are limited. For example, when encountering ground with a pile of sharp objects, the sharp objects may pierce the shoe cover and injure the user's feet. Utility Model Content
[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a multifunctional shoe cover. By adding multiple height-increasing studs to the sole of the shoe cover, the overall height of the shoe cover is increased. When users need to work or walk on muddy, wet, or surfaces with sharp objects, they can wear this shoe cover over their regular shoes to raise their foot height, effectively preventing their shoes from being pierced by sharp objects or sinking into muddy environments, thus protecting their feet. At the same time, the height-increasing studs are detachable, allowing users to change the height of the shoe cover by replacing them with studs of different heights to adapt to different usage scenarios. When the studs are damaged, the user can also replace them in a timely manner.
[0005] This utility model provides a multifunctional shoe cover, including a sole with several height-increasing shoe spikes and an upper integrally formed with the sole. The sole has several fixing holes evenly distributed, and each fixing hole is connected to a corresponding height-increasing shoe spike. The height-increasing shoe spike includes a four-prong nut and a height-increasing screw. The height-increasing screw has a threaded post at its top, and the four-prong nut has a threaded hole. The threaded post passes through the fixing hole and is screwed to the four-prong nut through the threaded hole.
[0006] The one-piece molded upper and sole form the basic structure of this shoe cover. Height-increasing studs are added to raise the overall height of the shoe cover, thus protecting the user's feet. This shoe cover can be worn on the outside of regular shoes. When the user needs to work or walk on muddy, wet, or surfaces with sharp objects, it effectively prevents the user's shoes from being pierced by sharp objects or sinking into the mud. The four-pronged nut and the height-increasing screw are screwed together, allowing the shoe studs to be detachably connected. Even when the shoe studs are completely removed, the height of the sole itself still provides a basic increase in height, allowing it to be used as a regular shoe cover.
[0007] In some embodiments, the height-increasing screw further includes a limiting plane, a hexagonal limiting post, and a screw head. The limiting plane is integrally connected to the lower part of the screw post, the hexagonal limiting post is integrally connected to the lower part of the limiting plane, and the screw head is integrally connected to the lower part of the hexagonal limiting post. The limiting plane abuts against the bottom surface of the shoe sole, serving to limit and distribute pressure, preventing the screw head from being pressed into the shoe sole under pressure. The hexagonal limiting post located between the limiting plane and the screw head facilitates the removal of the height-increasing screw. When the user rotates the four-prong nut and the height-increasing screw to separate them, the hexagonal limiting post acts as a pivot point, allowing the height-increasing screw to be quickly removed. The screw head is used to achieve the height-increasing function. By setting different screw head heights, the shoe cover can have different height increases.
[0008] In some embodiments, the four-pronged nut further includes a top surface and an extension prong. The top surface extends downward axially to form the screw hole, and the extension prong extends downward circumferentially from the top surface, located outside the screw hole. The four-pronged nut can provide a more uniform force distribution, distributing pressure across the entire shoe upper, allowing the platform spike to maintain the stability of the entire shoe cover even when only the tip is under force.
[0009] In some embodiments, both the screw hole and the screw post are located within the fixing hole and are screwed together. The extension claw on the outer side is engaged within the sole. The screw hole and screw post are concealed within the sole, effectively preventing movement of the height-increasing stud. The four-pronged nut, through the extension claw, inserts its prongs into the sole to stably fix the entire height-increasing stud, preventing it from detaching from the sole. When the height-increasing stud needs to be removed, it can be disassembled by rotating the height-increasing screw.
[0010] In some embodiments, the top surface abuts against the sole surface, and the limiting plane abuts against the bottom surface of the sole. The diameter of the limiting plane is larger than the diameter of the fixing hole. The cooperation between the top surface and the limiting plane stabilizes the sole between them, preventing displacement and wobbling. The size of the limiting plane is limited to prevent the spikes from inserting into the sole under force.
[0011] In some embodiments, the nail head includes a conical section and a raised section. The conical section is a cone with its bottom surface connected to the hexagonal limiting post. The raised section is a cylinder, with one end connected to the top of the cone and the other end being arc-shaped. Users can also wear the shoe cover barefoot, especially on soft sandy surfaces. The sharper tip can be directly inserted into the sand, increasing friction and stability, while the gradually increasing conical section disperses force, providing support and preventing the thin tip from breaking.
[0012] In some embodiments, the spike head is at least 3cm. A spike head that is too short provides limited height increase, especially when facing surfaces with sharp objects. In this case, shoe lifts can provide better protection for the user's feet.
[0013] In some embodiments, a plurality of elastic protrusions extend from the inner side of the shoe upper. One end of each elastic protrusion is connected to the shoe upper, and the other end of each elastic protrusion is spaced apart from the sole. The elastic protrusions increase friction and secure the user's foot or shoe. When the user needs to wear the shoe cover, they insert their foot into the shoe upper, and the elastic protrusions on the inner side of the upper bend and abut against the instep, thereby providing a limiting and securing effect. This design can accommodate shoes of different sizes or foot shapes, preventing the shoe or foot from slipping off.
[0014] In some embodiments, the shoe upper has friction zones on both outer sides, and these friction zones are recessed. When it is necessary to remove the shoe cover, the user can quickly remove it by kicking the friction zones on the sides, without having to put the shoe cover on or take it off by hand.
[0015] In some embodiments, the sole edge extends upwards with a fastening edge, the cross-section of which is inclined, and a limiting groove is provided at the connection between the fastening edge and the sole. The fastening edge is used to secure the shoe worn by the user, increasing friction and preventing the shoe cover from falling off. As the shoe walks, it gradually penetrates into the sole along the inclined fastening edge. The limiting groove at the connection between the sole and the fastening edge provides better fixation for the shoe that has slipped in.
[0016] By adopting the above technical solution, the beneficial effects of this utility model are:
[0017] This invention increases the overall height of a shoe cover by adding multiple height-increasing studs to the sole. When users need to work or walk on muddy, wet, or debris-filled surfaces, they can wear this shoe cover over their regular shoes to raise their foot height, effectively preventing their shoes from being pierced by sharp objects or sinking into mud, thus protecting their feet. The height-increasing studs are detachable, allowing users to change the height of the shoe cover to suit different usage scenarios. Damaged studs can also be replaced promptly. When the height-increasing studs are not installed, the shoe cover can be worn as a normal shoe cover.

[0048] Reference Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the shoe cover in some embodiments of this utility model.
[0049] According to some embodiments of the present invention, the present invention provides a multifunctional shoe cover, including a shoe sole 1 with a plurality of height-increasing shoe studs 2 and a shoe upper 3 integrally formed with the shoe sole 1. The shoe sole 1 has a plurality of fixing holes evenly distributed, and each fixing hole is connected to a corresponding height-increasing shoe stud 2. The height-increasing shoe stud 2 includes a four-prong nut 21 and a height-increasing screw 22. The top of the height-increasing screw 22 is provided with a threaded post 221, and the four-prong nut 21 is provided with a threaded hole 211. The threaded post 221 passes through the fixing hole and is screwed to the four-prong nut 21 through the threaded hole 211.
[0050] The one-piece molded upper 3 and sole 1 constitute the basic structure of the shoe cover. On this basis, the height of the entire shoe cover is increased by adding height-increasing shoe spikes 2, thereby achieving the purpose of protecting the user's feet. The shoe cover can be worn on the outside of regular shoes. When the user needs to work or walk on muddy, waterlogged or ground with sharp debris, it effectively prevents the user's shoes from being pierced by sharp debris or sinking into the muddy environment. The four-prong nut 21 and the height-increasing screw 22 are screwed together, so that the height-increasing shoe spikes 2 can be detached. When the height-increasing shoe spikes 2 are completely removed, the height of the sole 1 itself can also play a basic height-increasing role and be used as a regular shoe cover.
[0051] Reference Figure 2 , Figure 2 This is a schematic diagram of the disassembled structure of the height-increasing shoe nail in some embodiments of this utility model.
[0052] According to some embodiments of the present invention, optionally, the heightening screw 22 further includes a limiting plane 222, a hexagonal limiting post 223 and a screw head 224. The limiting plane 222 is integrally connected to the lower part of the screw post 221, the hexagonal limiting post 223 is integrally connected to the lower part of the limiting plane 222, and the screw head 224 is integrally connected to the lower part of the hexagonal limiting post 223. The limiting plane 222 abuts against the bottom surface of the sole 1, which serves to limit and disperse pressure, preventing the nail head 224 from being pressed into the sole 1 under pressure. The hexagonal limiting post 223 located between the limiting plane 222 and the nail head 224 is for easy disassembly of the height-increasing screw 22. When the user rotates the four-pronged nut 21 and the height-increasing screw 22 to separate them, the hexagonal limiting post 223 serves as a pivot point, allowing the height-increasing screw 22 to be quickly removed. The nail head 224 is used to achieve the height-increasing function. By setting different nail head 224 heights, the shoe cover can have different height increases.
[0053] The four-pronged nut 21 also includes a top surface 212 and an extension claw 213. The top surface 212 extends downward along its axis and has a screw hole 211. The extension claw 213 extends downward around the outer periphery of the top surface 212 and is located outside the screw hole 211. The four-pronged nut 21 can provide a more uniform force distribution, distributing pressure across the entire shoe upper 3, so that the height-increasing shoe spike 2 maintains the stability of the entire shoe cover even when only the tip is under force.
[0054] Both the screw hole 211 and the screw post 221 are located within the fixing hole and are screwed together. The extension claw 213 on the outer side is engaged within the sole 1. The screw hole 211 and the screw post 221 are hidden within the sole 1, effectively preventing the height-increasing stud from moving. The four-pronged nut 21 inserts its prongs into the sole 1 via the extension claw 213 to stably fix the position of the entire height-increasing stud 2, preventing it from detaching from the sole 1. When it is necessary to disassemble the height-increasing stud 2, it can be disassembled by rotating the height-increasing screw 22.
[0055] The nail head 224 includes a conical area 2241 and a raised area 2242. The conical area 2241 is a cone with its bottom surface connected to the hexagonal limiting post 223. The raised area 2242 is a cylinder, with one end connected to the top of the cone and the other end being arc-shaped. Users can also wear the shoe cover barefoot, especially when facing soft sand. The relatively sharp tip can be directly inserted into the sand, increasing friction and stability, while the gradually increasing conical area 2241 disperses the force, provides support, and prevents the thin tip from breaking.
[0056] Reference Figure 3-4 , Figure 3 This is a top view schematic diagram of the shoe cover in some embodiments of this utility model; Figure 4 This is a schematic diagram of the connection structure between the elastic protrusion and the shoe upper in some embodiments of this utility model.
[0057] According to some embodiments of this utility model, optionally, the top surface 212 abuts against the surface of the sole 1, and the limiting plane 222 abuts against the bottom surface of the sole 1, the diameter of the limiting plane 222 being larger than the diameter of the fixing hole. The cooperation between the top surface 212 and the limiting plane 222 ensures that the sole 1 is stably fixed between them, preventing displacement and shaking. The size of the limiting plane 222 is limited to prevent the heightening studs 2 from inserting into the sole 1 under force.
[0058] The spike head 224 must be at least 3cm long. A spike head 224 that is too short will have limited effect on increasing height, especially when facing surfaces with sharp objects. In this case, shoe lifts can provide better protection for the user's feet.
[0059] Several elastic protrusions 4 extend from the inner side of the shoe upper 3. One end of each elastic protrusion 4 is connected to the shoe upper 3, and the other end of each elastic protrusion 4 is spaced apart from the sole 1. The elastic protrusions 4 are designed to increase friction and secure the user's foot or shoe. When the user needs to wear the shoe cover, they insert their foot into the shoe upper 3. The elastic protrusions 4 on the inner side of the shoe upper 3 bend and abut against the instep, thereby limiting and securing the foot. This design can accommodate shoes of different sizes or foot shapes and prevent the shoe or foot from slipping off.
[0060] The shoe upper 3 has friction zones 5 on both outer sides, which are recessed. When it is necessary to remove the shoe cover, the user can kick the friction zones 5 on the sides to quickly remove the shoe cover without having to put it on or take it off by hand.
[0061] The sole 1 has an upwardly extending fastening edge 6, which is inclined in cross-section. A limiting groove 7 is provided at the connection between the fastening edge 6 and the sole 1. The fastening edge 6 is used to secure the user's shoe, increasing friction and preventing the shoe cover from falling off. As the shoe walks, it gradually penetrates deeper into the sole 1 along the inclined fastening edge 6. The limiting groove 7 at the connection between the sole 1 and the fastening edge 6 further secures the shoe as it slips in.
