Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a chair with a silent, non-slip foot pad and anti-fall-off structure. Background Technology

[0002] In daily life and office settings, chairs are indispensable pieces of furniture, and their user experience and functionality are of great concern. To avoid harsh noises caused by excessive friction between the chair and the ground during movement, and to prevent the chair from sliding and causing the user to tip over or shift position, most chairs currently feature non-slip, noise-reducing pads on the bottom of their legs. These pads are typically made of materials such as rubber or silicone, which combine elasticity and friction. They achieve a non-slip effect through contact with the ground and absorb the sound generated by friction using the material's own cushioning properties, thus achieving a quieter operation and significantly improving the comfort and environmental friendliness of the chair.

[0003] However, in practical applications, the existing anti-slip and silent chair leg pads have obvious structural design flaws, leading to a common problem of easy detachment during long-term use. Currently, most common anti-slip and silent chair leg pads on the market use a simple splicing method to connect to the chair legs: when using the splicing method, the leg pad and the chair leg are only fixed by the elasticity of the material itself. With frequent movement of the chair, changes in the load, and the influence of ambient temperature and humidity, the elasticity of the leg pad will gradually decrease, resulting in an increase in the gap between it and the chair leg, eventually causing it to detach from the chair leg. Once the anti-slip and noise-reducing foot pads detach from the chair legs, the chair not only loses its original anti-slip and noise-reducing functions—meaning the chair will directly rub against the ground when moved, generating significant noise and disturbing the surrounding environment—but also the friction between the chair legs and the ground is significantly reduced, increasing the risk of slipping. Furthermore, detached foot pads are small and usually scatter in inconspicuous places such as floor crevices and under furniture, making them difficult to find and collect quickly, turning them into frequently replaced consumables. This not only increases the user's operating costs, requiring regular purchases of new foot pads, but also may have an environmental impact due to indiscriminate disposal, which does not meet current green and environmentally friendly usage requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chair with a silent, anti-slip foot pad anti-detachment structure, which solves the technical problem that the existing chair's anti-slip and silent foot pad is prone to detachment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A chair with a silent, non-slip, and anti-fall-off foot pad structure includes a seat, two chair legs located below the seat and in contact with the ground, a connecting rod between the two chair legs, and foot pads installed at the bottom of the chair legs. Each chair leg has two foot pads, and a telescopic strip connects the two foot pads on each chair leg. Each foot pad is equipped with a locking element. When each foot pad is installed at the bottom of the chair leg, the locking element securely binds the foot pad to the chair leg to prevent the foot pad from falling off the chair leg.

[0006] Working principle: After installing the foot pads at the bottom of the chair legs, use the locking clips to securely fasten the foot pads to the chair legs, preventing them from detaching. Adjust the distance between the two foot pads by changing the length of the telescopic strip.

[0007] Beneficial effects: 1. This utility model incorporates a locking element on each foot pad. Once the foot pad is installed at the bottom of the chair leg, the locking element securely binds it to the leg, changing the existing method of relying solely on elastic clips to fix the foot pad. This locking structure prevents the foot pad from detaching from the chair leg due to weakened fixing force, ensuring a stable connection between the foot pad and the chair leg. This continuously enhances the anti-slip and noise reduction functions, significantly improving the safety and environmental friendliness of the chair.

[0008] 2. Each chair leg is equipped with two foot pads, connected by an adjustable telescopic strip. Users can adjust the distance between the two foot pads according to their actual needs (such as floor flatness, chair weight distribution, and personal usage habits). When the floor is slightly uneven, adjusting the foot pad spacing ensures that both pads are in stable contact with the ground, guaranteeing the overall stability of the chair. Furthermore, a reasonable foot pad spacing further distributes the pressure of the chair legs on the floor, reducing wear and tear. This design is suitable for various flooring materials (such as wood flooring, tile, and carpet) in homes, offices, and other settings, broadening the product's applicability and enhancing the user experience.

[0011] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0012] Example: like Figures 1-4 As shown, this utility model discloses a chair with a silent, anti-slip, and anti-fall-off foot pad structure, specifically including four basic components: a seat 1, chair legs 2, connecting rods 3, and foot pads 4. These components work together to achieve the chair's support, silent operation, and anti-slip / fall-off effects. The seat 1, as the main load-bearing component, is made of wood or plastic to meet the weight-bearing requirements of daily sitting. The upper surface of the seat 1 can be provided with anti-slip textures or soft pads to improve sitting comfort. Reinforcing ribs are provided at the connection between the lower surface of the seat 1 and the chair legs 2 to enhance connection strength and prevent the seat from separating from the chair legs after long-term use. Two chair legs 2 are provided, symmetrically fixed below the seat 1 and perpendicular to the ground. Each chair leg 2 extends along the length of the seat 1, providing stable support for the chair. The chair legs 2 are preferably made of metal or high-strength plastic to ensure structural strength. The bottom of the chair legs 2 has grooves that fit the U-shaped structure of the foot pads 4, allowing for a better fit and reducing relative displacement. The surface of the chair legs 2 is also treated with rust prevention (metal material) to extend service life. The connecting rods 3... The connecting rod 3 is horizontally fixed between the two chair legs 2, near the middle of the chair legs 2, to enhance the connection stability of the two chair legs 2 and prevent the chair legs 2 from shifting laterally during use. The connecting rod 3 adopts a cylindrical or square structure, and its two ends are fixed to the chair legs 2 by bolts. The surface of the connecting rod 3 is also smoothed to prevent scratching clothing during use. The foot pad 4 is installed at the bottom of the chair legs 2 and is the core component to achieve the functions of quietness and anti-slip. It adopts a U-shaped structure design and is made of TPE (thermoplastic elastomer). TPE material has both elasticity and wear resistance. It can not only cushion the friction between the chair and the ground when the chair moves to achieve a quiet effect through its own elasticity, but also use the friction of the material surface to prevent the chair from sliding. At the same time, the U-shaped structure can fit tightly with the bottom of the chair legs 2 to improve the installation adaptability.

[0013] Each chair leg 2 is equipped with two foot pads 4, which are spaced apart along the length of the chair leg 2. A telescopic strip connects the two foot pads 4 on each chair leg 2, allowing adjustment of the distance between the two foot pads 4 to suit different ground conditions and usage needs. Specifically, the telescopic strip includes a sleeve 501 and two moving rods 502. The sleeve 501 is a hollow cylindrical structure, with its inner diameter matching the outer diameter of the moving rods 502, ensuring smooth sliding within the sleeve 501. The two moving rods 502 extend into the sleeve 501 from both ends, and the end of each moving rod 502 away from the sleeve 501 is fixed to the side wall of the corresponding foot pad 4 away from the connecting rod 3 by welding or bolting. When adjusting the distance between the two foot pads 4, simply push the moving rod 502 to slide within the sleeve 501, changing the overall length of the telescopic strip and thus adjusting the distance between the two foot pads 4. This operation is convenient and the adjustment range is flexible.

[0014] To avoid the instability of the foot pads 4 due to insufficient support from a single telescopic bar, and to prevent interference between the telescopic bar and the connecting rod 3, an additional secondary telescopic bar is connected between the two foot pads 4 on each chair leg 2. The secondary telescopic bar is located on the side of the chair leg 2 closest to the connecting rod 3, forming a symmetrical support structure with the aforementioned telescopic bar, further improving the connection stability of the two foot pads 4. The secondary telescopic strip includes a shaped secondary sleeve 601 and two secondary moving rods 602. The main structure of the shaped secondary sleeve 601 is the same as that of the sleeve 501, both being hollow structures adapted to the sliding of the secondary moving rods 602. The core improvement is that the shaped secondary sleeve 601 has an integrally formed protrusion. This protrusion protrudes upward and is located above the connecting rod 3. The height of the protrusion is higher than that of the connecting rod 3. When the secondary telescopic strip is installed between the two foot pads 4, the protrusion can avoid the connecting rod 3, preventing the secondary telescopic strip from colliding or getting stuck with the connecting rod 3, ensuring that the foot pads 4 can be smoothly installed at the bottom of the chair leg 2. The two secondary moving rods 602 extend into the interior of the shaped secondary sleeve 601 from both ends, and the end of each secondary moving rod 602 away from the shaped secondary sleeve 601 is fixedly connected to the side wall of the corresponding foot pad 4 near the connecting rod 3. The connection method between the secondary moving rods 602 and the foot pads 4 is the same as that of the moving rods 502, ensuring connection strength.

[0015] It should be noted that the sleeve 501, the moving rod 502, the irregular secondary sleeve 601, and the secondary moving rod 602 are all made of ABS plastic. This material has high strength and wear resistance, and is lightweight, so it will not increase the overall weight of the chair. At the same time, the toughness of ABS plastic can prevent the parts from breaking during adjustment, ensuring the long-term stable use of the telescopic structure.

[0016] To address the issue of existing foot pads 4 easily detaching, each foot pad 4 is equipped with a locking component. The locking component securely binds the foot pad 4 to the chair leg 2 through a "wrapping and fixing" method. Structurally, each foot pad 4 has an extension strip 7 integrally formed on one side of its top. The extension strip 7 is made of the same material as the foot pad 4, TPE, which has a certain degree of flexibility and can be bent. The locking component includes a female buckle 801 and a male buckle 802. The female buckle 801 is fixed to the inner surface of the extension strip 7 (i.e., the side facing the foot pad 4 after bending) by heat pressing, while the male buckle 802 is correspondingly fixed to the side wall of the foot pad 4 near the connecting rod 3, and the positions of the female buckle 801 and the male buckle 802 are mutually compatible. When the foot pad 4 is installed at the bottom of the chair leg 2, first, the U-shaped foot pad 4 is placed on the bottom of the chair leg 2, so that the bottom of the chair leg 2 is embedded in the U-shaped groove of the foot pad 4. Then, the extension strip 7 is bent towards the foot pad 4 until the extension strip 7 covers the outer surface of the foot pad 4. At this time, the female buckle 801 and the male buckle 802 are interlocked. The clamping force of the interlocking structure firmly fixes the foot pad 4 to the chair leg 2, effectively preventing the foot pad 4 from falling off the chair leg 2 when the chair moves or the load changes. It should be noted that the female buckle 801 and the male buckle 802 are made of nylon. Nylon has high toughness and fatigue resistance, and can maintain a stable clamping force after repeated interlocking. Moreover, nylon is compatible with TPE material and will not cause connection failure due to material differences.

[0017] Working principle: During actual installation, firstly, fix the two chair legs 2 symmetrically under the seat 1, then install the connecting rod 3 horizontally between the two chair legs 2 to complete the assembly of the main frame of the chair; then take two foot pads 4, align their U-shaped grooves with the bottom of one of the chair legs 2 and install them, at which point the protrusion of the irregular secondary sleeve 601 is located above the connecting rod 3 to avoid interference with the connecting rod 3; finally, bend the extension strip 7 so that the female buckle 801 and the male buckle 802 are engaged to complete the installation of the foot pad 4 of that chair leg 2, and complete the installation of the foot pad 4 of the other chair leg 2 in the same way.

[0018] During use, if the ground is uneven, the distance between the two foot pads 4 can be adjusted by pushing the moving rod 502 to slide within the sleeve 501 and pushing the secondary moving rod 602 to slide within the irregular secondary sleeve 601, so that both foot pads 4 can stably contact the ground and ensure the stability of the chair. At the same time, the TPE material foot pads 4 can effectively reduce the friction noise between the chair and the ground when moving, achieving a silent effect. The locking mechanism ensures that the foot pads 4 will not fall off, greatly improving the reliability and service life of the chair.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
