AI Technical Summary
Traditional carpets, especially thick and flexible ones, suffer from insufficient anti-slip performance on smooth surfaces, leading to displacement and potential safety risks, and existing bottom-mounted anti-slip solutions fail to effectively address these issues in multi-layer carpets.
A comfort double-layer carpet design featuring a comfort layer with an elastic sponge, a support layer with a low-density hard sponge, a backing fabric, and a non-slip coating on the bottom, reinforced by sewing threads that divide the carpet into blocks, providing stability and uniform anti-slip performance.
The design enhances anti-slip performance, reduces layer displacement, and extends the carpet's lifespan by distributing load laterally, ensuring comfort and stability while preventing localized stress damage.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of household items, and particularly to a comfort double - structure anti - slip carpet.
Background Art
[0002] Carpets are common household items that can enhance the comfort and beauty of life. However, traditional carpets often have the problem of insufficient anti - slip performance during use. Especially on smooth floor surfaces, displacement is likely to occur, which not only affects the use experience but also poses potential safety risks. A common solution is to install anti - slip members at the bottom of the carpet and fix the anti - slip members to the bottom of the carpet using pasting or sewing. Although this can solve the problem that the carpet is likely to be displaced, such an installation is suitable for single - layer carpets with a small thickness and large hardness. For thick, comfortable carpets with a soft texture and especially those containing a flexible filler, there are many problems with such anti - slip measures, such as layer displacement. When the surface layer receives force, it moves relatively, bringing not only a greater risk of falling but also burden on the seams or edges of the carpet, leading to damage to the carpet.
[0003] Therefore, for the anti - slip of multi - layer carpets with a certain thickness, simply adding anti - slip members to the bottom of the carpet has little effect.
[0004] In response to the above problems, the present invention provides a comfort double - structure anti - slip carpet, which includes a comfort layer and a support layer. The comfort layer is located above the support layer. A pile layer is provided on the surface of the comfort layer. A lining cloth is provided between the comfort layer and the support layer. An anti - slip coating is provided on the bottom surface of the support layer. The comfort double - structure anti - slip carpet of the present invention is evenly divided into several square blocks by sewing threads that penetrate vertically with respect to the surface.
[0005] In this invention, the comfort layer uses an elastic sponge with a density of 50-60D and a thickness controlled to 0.5-2cm. Its surface pile layer provides a soft, skin-friendly feel, offering users a comfortable treading experience. The support layer is made of a low-density hard sponge with a density of 30-40D and a thickness of 0.5-2cm. This provides stable support to the overall structure and prevents excessive sinking during carpet use. The backing fabric is placed between the comfort layer and the support layer, serving a connecting and reinforcing role, strengthening the bonding force between the two layers. The anti-slip coating on the bottom surface of the support layer uses a fiber cloth coated with rubber, silica gel, or PVC on the surface, effectively increasing the frictional force between the carpet and the ground and preventing the carpet from sliding. Sewing threads that penetrate perpendicularly to the surface evenly divide the carpet into several rectangular blocks. This design not only fixes each layer structure and avoids displacement between layers, but also makes the overall structure of the carpet more stable and extends its lifespan.
[0006] The comfortable double-layered anti-slip carpet of this invention has the following advantages compared to conventional thick carpets: 1. By applying an anti-slip component to the fiber fabric, the carpet is given stable anti-slip performance, and this anti-slip structure is more robust and uniform compared to the method of bonding anti-slip particles. 2. By evenly dividing the carpet into several rectangular blocks with sewing threads that penetrate perpendicularly to the surface, relative displacement of the surface layer can be reduced. The sewing threads penetrate the backing fabric, transmitting the load laterally and avoiding damage caused by localized stress concentration. The load is transmitted laterally along the backing fabric, protecting the upper and lower layers of sponge and extending the life of the sponge. 3. This invention uses sponges of different densities as fillings; the lower layer of hard sponge provides support, and the upper layer of elastic sponge provides flexibility and resilience. The two work together to provide sufficient comfort to the carpet while also making it resistant to deformation. [Brief explanation of the drawing]
