Description

Spiral strips with reinforcing ribs to improve durability Technical Field

[0001] This application relates to the field of barbed strip technology, and in particular to barbed strips with reinforcing ribs to improve durability. Background Technology

[0002] Velcro strips, also known as hook and loop fasteners, are a common type of fastener. They consist of a barbed surface with barbs and a looped surface. The connection and fixation are achieved by the hooks and loops engaging. In seat manufacturing and related fields, Velcro (barbed strips) are widely used for fixing seats and cushions due to their convenient installation and repeated opening and closing characteristics.

[0003] The barbed strip mainly consists of a hooked side and a pile side, achieving fixation through the mechanical connection between the hooks and the pile. Traditional barbed strips suffer from poor strength; under the impact of frequent seat adjustments and people sitting and standing, the base fabric of the barbed strip is easily torn, and the hooks often break due to stress concentration, leading to fixation failure. Furthermore, barbed strips have poor environmental adaptability, and ordinary barbed strips are not tensile-resistant; when moving seats or cushions and subjecting them to external pulling forces, they are prone to deformation and elongation, affecting the fixation effect. Therefore, we propose a barbed strip with reinforcing ribs to improve durability. Summary of the Invention

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] As shown in the figures, this embodiment provides a barbed strip with reinforcing ribs to improve durability. As shown in Figures 1-5, it includes a female barbed strip patch 1 and a female barbed strip patch 12. The top of the female barbed strip patch 1 is connected to the bottom hook-and-loop connection of the female barbed strip patch 12. It also includes:

[0023] Two adhesive layers 2 are fixedly installed at the bottom of the barbed strip mother patch 1 and the top of the barbed strip daughter patch 12, respectively. Several grooves 3 are opened at the top of the barbed strip mother patch 1, and several ventilation grooves 4 are opened between two adjacent grooves 3. Several connecting rods 6 are fixedly installed in the grooves 3. Four hooks 7 are fixedly installed at the top of the connecting rods 6, and several barbs are fixedly installed on the inner side of each of the four hooks 7.

[0024] A performance enhancement component is located within the barbed strip mother plate 1 and is used to enhance the performance of the barbed strip mother plate 1.

[0025] When securing the seat cushion to the seat frame using the bristle strips, cut the appropriate lengths of the bristle strip mother sticker 1 and bristle strip daughter sticker 12 using scissors and a ruler, according to the seat's usage requirements. Then, carefully peel off the protective paper from the bottom adhesive layer 2 of the bristle strip mother sticker 1. Align the bristle strip mother sticker 1 with the installation position on the seat and press it in place gradually from one end, ensuring the mother sticker 1 is flat and wrinkle-free. At this point, the adhesive layer 2 adheres to the surface of the seat frame, ensuring the bristle strip mother sticker 1 is fixed to the seat frame surface. Next, remove the seat cushion and carefully peel off the protective paper from the bottom adhesive layer 2 of the bristle strip daughter sticker 12. Align the bristle strip daughter sticker 12 with the seat cushion installation position and press it in place gradually from one end, ensuring the bristle strip daughter sticker 12 is flat and wrinkle-free. At this point, the adhesive layer 2 adheres to the surface of the seat frame. The adhesive is used to bond the seat cushion, ensuring that the barbed strip 12 is fixed to the surface of the seat frame. Then, the barbed strip 12 at the bottom of the seat cushion is aligned with the barbed strip mother sticker 1 on the seat frame, and the seat cushion is pressed firmly so that the barbs of the hook 7 are fully embedded in the fibers of the barbed strip 12, ensuring that the barbed strip 12 and the barbed strip mother sticker 1 are tightly attached, thereby fixing the seat cushion to the seat frame. At the same time, the connecting rod 6 and the hook 7 provide stable support, enhance structural stability, and ensure that the barbs function effectively. The ventilation groove 4 can improve air circulation, reduce stuffiness and moisture accumulation, improve the user experience, and prevent the adhesion performance from deteriorating due to moisture. The set of several reinforcing ribs 5 can effectively suppress the plastic deformation of the material and reduce cracks or delamination of the barbed strip mother sticker 1 due to fatigue.

[0026] The performance enhancement components significantly enhance the overall strength of the barb strip mother plate 1, ensuring that the barb strip mother plate 1 will not deform or elongate when subjected to external force, thus greatly improving the stability of the barb strip.

[0027] Please refer to Figure 5. The performance enhancement component includes a base fabric reinforcement layer 8, an elastic buffer layer 9 at the bottom of the base fabric reinforcement layer 8, a tensile layer 10 at the bottom of the elastic buffer layer 9, and a waterproof sealing layer 11 at the bottom of the tensile layer 10.

[0028] The base fabric reinforcement layer 8, made of nylon fiber, provides basic strength support for the barbed strip mother patch 1, reducing damage to the base fabric caused by external forces. This reduces the overall replacement frequency of the barbed strip, saves maintenance costs, and extends the service life of the barbed strip mother patch 1. The elastic buffer layer 9, made of silicone, effectively absorbs impact forces and buffers stress concentration caused by the separation of the barbs from the surface. Simultaneously, the elasticity of the silicone allows the barbed strip to better adapt to uneven surfaces, ensuring a tight fit to the object's contour during application and filling gaps. The gaps enhance adhesion stability; the tensile strength layer 10, made of Kevlar fiber, significantly improves the tensile strength of the bristle strip mother patch 1, effectively resisting external pulling forces and preventing the bristle strip mother patch 1 from being stretched, deformed, or even broken, ensuring reliable fixation; the waterproof sealing layer 11, made of polyurethane, effectively prevents moisture from penetrating into the bristle strip, preventing problems such as mold growth on the base fabric, rust on metal parts, and glue failure, protecting the internal structure and material properties of the bristle strip, and extending the product's service life.

[0029] Please refer to Figure 5. The base fabric reinforcement layer 8, elastic buffer layer 9, tensile layer 10, and waterproof sealing layer 11 are bonded together with adhesive.

[0030] The adhesive is used to ensure that the base fabric reinforcement layer 8, elastic buffer layer 9, tensile layer 10 and waterproof sealing layer 11 are bonded together.

[0031] Please refer to Figure 5. The material of the base fabric reinforcement layer 8 is nylon fiber, and the thickness of the base fabric reinforcement layer 8 is 0.3mm-0.5mm.

[0032] The base fabric reinforcement layer 8, made of nylon fiber, provides basic strength support for the barbed strip mother patch 1, reducing damage to the base fabric caused by external forces, thereby reducing the overall replacement frequency of the barbed strip, saving maintenance costs, and extending the service life of the barbed strip mother patch 1.

[0033] Please refer to Figure 5. The elastic buffer layer 9 is made of silicone, and the thickness of the elastic buffer layer 9 is 1mm-2mm.

[0034] Among them, the elastic buffer layer 9 is made of silicone, which can effectively absorb impact force and buffer the stress concentration generated when the barbs separate from the rough surface. At the same time, the elasticity of silicone allows the barb strips to better adapt to uneven surfaces, and can closely fit the contour of the object during pasting, fill gaps, and enhance adhesion stability.

[0035] Please refer to Figure 5. The tensile layer 10 is made of Kevlar fiber, and the thickness of the tensile layer 10 is 0.1mm-0.2mm.

[0036] Among them, the tensile layer 10, which is made of Kevlar fiber, can significantly improve the tensile performance of the barbed strip mother patch 1, effectively resist external pulling force, prevent the barbed strip mother patch 1 from being stretched, deformed or even broken, and ensure the reliability of the fixation.

[0037] Please refer to Figure 5. The waterproof sealing layer 11 is made of polyurethane, and the thickness of the waterproof sealing layer 11 is 0.1mm-0.2mm.

[0038] The waterproof sealing layer 11, made of polyurethane, effectively prevents moisture from seeping into the interior of the bristle strip, thus preventing problems such as mold growth on the base fabric, rust on metal parts, and glue failure. This protects the internal structure and material properties of the bristle strip and extends the product's service life.

[0039] The implementation principle of the reinforced ribs for improved durability in this application embodiment is as follows: When it is necessary to fix the seat cushion to the seat frame using ribs, cut appropriate lengths of rib mother sticker 1 and rib sub sticker 12 according to the usage requirements of the seat. Then, carefully peel off the protective paper of the bottom adhesive layer 2 of the rib mother sticker 1, align the rib mother sticker 1 with the installation position on the seat, and gradually press and adhere it from one end to ensure that the rib mother sticker 1 is flat and wrinkle-free. At this time, the glue on the adhesive layer 2 adheres to the surface of the seat frame, ensuring that the rib mother sticker 1 is fixed to the surface of the seat frame. Then, remove the seat cushion, carefully peel off the protective paper of the bottom adhesive layer 2 of the rib sub sticker 12, align the rib sub sticker 12 with the installation position of the seat cushion, and gradually press and adhere it from one end to ensure that the rib sub sticker 12 is flat and wrinkle-free. When the cushion wrinkles, the adhesive on the bonding layer 2 adheres to the seat cushion, ensuring that the bristle strip 12 is fixed to the surface of the seat frame. Then, align the bristle strip 12 at the bottom of the seat cushion with the bristle strip mother sticker 1 on the seat frame and press the seat cushion firmly so that the barbs of the hook 7 are fully embedded in the fibers of the bristle strip 12, ensuring that the bristle strip 12 and the bristle strip mother sticker 1 are tightly attached, thereby fixing the seat cushion to the seat frame. At the same time, the connecting rod 6 and the hook 7 provide stable support, enhance structural stability, and ensure that the barbs function effectively. The ventilation groove 4 can improve air circulation, reduce stuffiness and moisture accumulation, improve the user experience, and prevent the adhesion performance from decreasing due to moisture. The several reinforcing ribs 5 can effectively suppress the plastic deformation of the material and reduce cracks or delamination of the bristle strip mother sticker 1 due to fatigue.

[0040] The base fabric reinforcement layer 8, made of nylon fiber, provides basic strength support for the barbed strip mother patch 1, reducing damage to the base fabric caused by external forces. This reduces the overall replacement frequency of the barbed strip, saves maintenance costs, and extends the service life of the barbed strip mother patch 1. The elastic buffer layer 9, made of silicone, effectively absorbs impact forces and buffers stress concentration caused by the separation of the barbs from the surface. Simultaneously, the elasticity of the silicone allows the barbed strip to better adapt to uneven surfaces, ensuring a tight fit to the object's contours and filling gaps during application. The addition of a tensile layer 10, made of Kevlar fiber, significantly enhances the tensile strength of the bristle strip mother-attachment 1, effectively resisting external pulling forces and preventing the bristle strip mother-attachment 1 from being stretched, deformed, or even broken, thus ensuring reliable fixation. The addition of a waterproof sealing layer 11, made of polyurethane, effectively prevents moisture from penetrating the bristle strip, preventing problems such as mold growth on the base fabric, rust on metal parts, and adhesive failure, protecting the internal structure and material properties of the bristle strip, and extending the product's service life.
