[0002] Table and chair legs (collectively referred to as table and chair legs) are generally made of wood or metal rods. If they come into direct contact with the floor when moved, they can easily scratch the floor and produce unpleasant noise. Therefore, table and chair leg covers have been designed to fit over the table and chair legs to prevent floor wear and eliminate noise generated when the tables and chairs are dragged.
[0003] Currently, most table and chair leg covers on the market are made of non-woven fabric or cloth. After contacting and rubbing against the floor, they easily attract hair, dust and other debris, which not only affects the appearance but also increases the difficulty of cleaning. In addition, table and chair leg covers with impurities will affect the slip-aiding performance, making the non-woven fabric or cloth structure easy to wear through, and the chair will make abnormal noises when dragging. Utility Model Content

[0020] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0021] refer to Figures 1 to 4 A foot cover includes a foot cover body 10 and a foot cover bottom 20. The foot cover bottom 20 is disposed at the bottom of the foot cover body 10. The foot cover bottom 20 includes a smooth layered structure 21 and an antistatic layered structure 22. The smooth layered structure 21 includes an adhesive layer 211 and an adhesive layer 212. The adhesive layer 211 is used to bond the adhesive layer 212 to the bottom of the foot cover body 10. One side of the adhesive layer 211 is bonded to the foot cover body 10, and the other side is bonded to the adhesive layer 212. The antistatic layered structure 22 includes an adhesive layer 221 and a conductive layer 222. The conductive layer 222 is formed by a blend of conductive fibers and abrasion-resistant fiber materials such as nylon fibers. The adhesive layer 221 is used to bond the conductive layer 222 and the adhesive layer 212. One side of the adhesive layer 221 is bonded to the adhesive layer 212, and the other side is bonded to the conductive layer 222.
[0022] The adhesive layer 211 is made of high-density non-woven fabric. The use of high-density non-woven fabric in the adhesive layer 211 ensures a tight fit between the bottom of the foot cover body 10 and the adhesive layer 212, preventing separation and detachment after long-term use and extending the service life. The adhesive layer 212 is made of EVA (ethylene-vinyl acetate copolymer) foam material, which has the characteristics of high transparency, durability, adhesion, low melting point, and easy processing. It can provide a neat and smooth surface and is tightly bonded to the adhesive layer 211.
[0023] The adhesive layer 221 is made of PU (polyurethane), which has high polarity and activity, exhibiting good adhesion to various metals and non-metals. The wear-resistant fiber material in the conductive layer 222 is polyamide fiber, which possesses properties such as non-sticking to hair, anti-static properties, wear resistance, water resistance, slip resistance, and sound insulation. It is suitable for various flooring types, including ceramic tile, wood flooring, and carpet flooring. The conductive layer 222 is formed by blending the adhesive layer 221 with conductive fibers such as metal fibers, carbon fibers, and graphene fibers. A special process is used to press the adhesive layer 221 and the conductive layer 222 together, enhancing the stability of the conductive layer 222 and its tightness with the adhesive layer 221. In this embodiment, the adhesive layer 221 uses PU material, while the conductive layer 222 uses a blend of wear-resistant polyamide fiber and conductive fibers, resulting in a smoother and more delicate surface that effectively improves conductivity while maintaining good flexibility and durability. Combining the advantages of both materials creates a composite fiber with high conductivity and good mechanical properties, achieving both anti-static and wear-resistant effects.
[0024] The foot cover body 10 is made of elastic material. The foot cover body 10 has a sleeve hole 11 and a cavity 12. The diameter of the sleeve hole 11 is smaller than the inner diameter of the cavity 12.
[0025] The leg cover body 10 is made of an elastic material, such as thermoplastic elastomer (TPE), rubber, silicone, or other soft and highly elastic materials, allowing the leg cover to fit snugly against chair legs or table legs of various shapes and sizes, ensuring a stable installation and preventing it from easily falling off. The diameter of the sleeve hole 11 is designed to be smaller than the inner diameter of the cavity 12, which helps the leg cover achieve a tight fit when it is put on the chair leg or table leg through the expansion and contraction of the elastic material.
[0026] In other embodiments, the TPE material used in the foot cover body 10 can be further optimized, such as by adding anti-slip textures or adjusting the material hardness, to improve comfort.
[0027] The bottom of the cavity 12 is provided with a rectangular array of multiple anti-slip protrusions 13, and anti-slip grooves 14 are provided between the anti-slip protrusions 13. The anti-slip protrusions 13 are square in shape, and the size of the square anti-slip protrusions 13 gradually increases from top to bottom. When the table and chair are subjected to force, the seat feet press down on the anti-slip protrusions 13, increasing the contact area between the seat feet and the anti-slip protrusions 13 and improving the friction between the two. At the same time, when the table and chair are subjected to force, the table and chair feet increase the pressure between the bottom cover 20 and the ground, increasing the friction between the bottom cover 20 and the ground, which helps to further improve the anti-slip effect of the table and chair feet cover.
[0028] The outer side wall of the foot cover body 10 is provided with an annular limiting groove 15, and the edge opening of the bottom cover 20 is fixedly inserted into the annular limiting groove 15 to improve the connection effect between the bottom cover 20 and the foot cover body 10.
[0029] The bottom outer side of the foot cover body 10 is a downward protruding convex surface, and the cross-section of the convex surface is a circular arc surface. The bottom of the foot cover 20 is also a circular arc surface, which reduces the contact area between the foot cover 20 and the ground, making it easier for the table and chair foot covers to move on the ground. When the chair is under force, the chair foot makes the bottom of the chair foot cover 20 flat, increasing the contact area and friction between the chair foot cover and the ground.
[0030] This embodiment proposes a table and chair leg cover. The leg cover body 10 is made of elastic material, which can fit tightly to the table and chair legs and improve installation reliability. The anti-static layered structure 22 improves the conductivity and wear resistance of the table and chair leg cover, and has the effect of not sticking to hair and being durable. The smooth layered structure 21 makes the leg cover body 10 and the cover bottom 20 fit more tightly.
[0031] A method for manufacturing table and chair leg covers includes the following steps:
[0032] Making the bottom sheet: Conductive fibers are woven into antistatic fibers using a blending process to form a conductive layer fabric. Soft rubber material is then rolled and bonded onto the conductive layer fabric using a roller press to create an antistatic layered bottom sheet. The conductive fibers can be metal fibers, carbon fibers, or graphene fibers, the antistatic fibers can be nylon fibers, and the soft rubber material is PU material.
[0033] The bonding layer material is glued to the bottom sheet, and the adhesive layer material is glued to the bonding layer material. The bonding is rolled using a roller press, and the pieces are cut using a vertical cutter. The cut pieces are baked and softened in an oven, and the softened pieces are placed in a mold for hot pressing and shaping. The edges are then trimmed using a punch press to obtain the bottom of the table and chair leg cover. The adhesive layer material is made of non-woven fabric, and the bonding layer material is made of EVA.
[0034] Injection molding: The base is placed in the cavity of the injection mold, the mold is closed and thermoplastic material is injected to form the leg cover body, which is combined with the base to obtain the table and chair leg cover. The thermoplastic material is TPE, rubber, silicone or other soft and elastic materials.
[0035] Example 1
[0036] A conductive layer fabric was formed by blending graphene fibers with nylon fibers, and the surface resistivity was measured to be 10. 6 Ω / sq, using a roller press, PU material is rolled and bonded onto the conductive layer fabric to obtain an antistatic layered bottom sheet. EVA bonding material is then bonded to the bottom sheet, and non-woven adhesive layer material is pasted onto the bonding material. The sheets are rolled and bonded, cut, and baked in an oven at 195℃ for 5 minutes. After hot pressing and shaping, the edges are trimmed to obtain the bottom of the table and chair leg sleeve. The bottom is placed in the mold cavity, and rubber is injected to produce 10 table and chair leg sleeves with a diameter of 1 inch.
[0037] Example 2
[0038] A conductive layer fabric was formed by blending aluminum fibers and nylon fibers, and the surface resistivity was measured to be 10. 7 Ω / sq, PU material is rolled and bonded to the conductive layer fabric to obtain an antistatic layered bottom sheet. EVA bonding material is bonded to the bottom sheet, and non-woven adhesive layer material is pasted onto the bonding material. Roll and bond, cut the sheet, and bake in an oven at 195℃ for 5 minutes. Hot press and shape, trim the edges to obtain the bottom of the table and chair leg cover. Place the bottom of the cover in the mold cavity and inject silicone to make 10 table and chair leg covers with a diameter of 1 inch.
[0039] Five table and chair leg covers each from Examples 1 and 2 were rubbed using a wear-resistant machine (model JQ-896) from Dongguan Jianqiao Testing Equipment Co., Ltd. under a load of 50 kg and 5000 opening and closing cycles. None of the five table and chair leg covers from Examples 1 and 2 showed any glue residue or tearing. Five table and chair leg covers each from Examples 1 and 2 were then rubbed using a high and low temperature machine (model HT-KIW40-150L) from Dongguan Huitai Instrument Equipment Co., Ltd., under varying temperatures from 70℃ to -20℃. None of the five table and chair leg covers from Examples 1 and 2 showed any glue residue or deformation.
