Description

Technical Field

[0001] This utility model relates to the field of home protection products technology, specifically to a stair mat. Background Technology

[0002] Stair mats, as a common home protection product, are primarily used on stair steps to provide anti-slip, shock absorption, protection of the step surface, and beautification of the environment.

[0003] However, existing "foldable" stair mats on the market still have many structural defects and cannot meet users' needs for multi-functionality and multi-angle adaptability. Specific problems are as follows: First, existing "foldable" stair mats mostly achieve bending through edge fixing creases or rigid connection structures, which can only complete a single right-angle bend. They are completely unable to adapt to non-right-angle scenarios such as rounded transition stair steps and irregularly shaped furniture edges, resulting in their use only at the junction of the vertical and horizontal surfaces of specific right-angle staircases. The scene adaptability is insufficient and cannot meet diverse usage needs. Second, due to residual fixing creases or deformation of rigid structures, the surface flatness error of existing products after unfolding generally exceeds 8mm / m, far exceeding the flatness standard of ≤2mm / m for household products. They are not suitable for flat use on the ground, tabletops, etc., and cannot realize the multi-functionality of stair mats, floor mats, or table mats.

[0004] In summary, existing stair mats have significant shortcomings in terms of bending flexibility, scene adaptability, flat laying practicality, and support stability. There is an urgent need for a stair mat that can overcome these limitations and achieve multi-angle bending and multi-scene flat laying. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a stair mat that, through optimized layer structure design and the inclusion of malleable support components, achieves the dual functions of bending at any angle within the range of 0°-180° and laying flat, while simultaneously improving support and adhesive stability to meet diverse usage needs.

[0006] Therefore, the purpose of this utility model is to provide a stair mat.

[0007] To achieve the purpose of this utility model, the technical solution of this utility model provides a stair mat that, from top to bottom, comprises: a carpet layer, a filling layer, and a self-adhesive bottom layer. The stair mat body has a first end face and a second end face along its length. A plastic support member is embedded in the middle of the filling layer. The plastic support member is bendable and is used to allow the first end face and the second end face to form an included angle α. Wherein, 0°≤α≤180°; when α is 0°, the stair mat is in a flat state; when α is 180°, the stair mat is in a folded state.

[0008] In one technical solution of this utility model, both the stair mat body and the plastic support body have thickness; wherein, the distance from the center line of the thickness of the plastic support body to the side of the self-adhesive bottom layer away from the filling layer is 15%-25% of the thickness of the stair mat body.

[0009] In one technical solution of this utility model, the thickness of the stair mat body is 5mm-15mm.

[0010] In one technical solution of this utility model, the thickness of the blanket surface layer is 3mm-10mm; the material of the blanket surface layer is a multi-layer textile fabric, which includes at least one of polyester fiber composite fabric and nylon composite fabric.

[0011] In one technical solution of this utility model, the thickness of the filling layer is 1.5mm-4.5mm; the material of the filling layer is non-woven fabric.

[0012] In one technical solution of this utility model, the thickness of the plastic support is 0.3mm-0.8mm; the material of the plastic support is selected from at least one of aluminum, iron and copper.

[0013] In one technical solution of this utility model, the thickness of the self-adhesive base layer is 0.5mm-1.2mm; the material of the self-adhesive base layer is TRE material.

[0014] In one technical solution of this utility model, the width of the plastic support is the same as the width of the stair mat body; the length of the plastic support is 3cm-10cm.

[0015] In one technical solution of this utility model, the number of plastic support members is one or more; wherein, the number of plastic support members is arranged parallel and spaced apart along the length direction of the stair mat body.

[0016] In one technical solution of this utility model, the stair mat also includes a release film, which is disposed on the side of the self-adhesive bottom layer away from the filling layer; the carpet layer, the filling layer, the plastic support member and the self-adhesive bottom layer are composited by hot melt adhesive.

[0017] The technical solution provided by this utility model can achieve at least one of the following effects: (1) Adaptable to more scenarios: Through the free bending function of the plastic support, the stair mat can be adapted to various scenarios such as right-angle stairs, arc transition stairs, and irregular furniture edges. At the same time, it can be laid flat on the ground and tabletop, effectively improving the scene adaptability and realizing one item for multiple uses. (2) Improve bending stability and fit. The design of the support thickness position avoids the problem of support exposure and easy wear caused by the position being too shallow, and also prevents the position from affecting the bending flexibility if it is too deep. It can provide stable shaping support for bending. With the thickness and material of each layer structure, each layer can deform synchronously after bending, without wrinkles or curling edges, and the stability of fitting the steps or furniture surface is significantly improved.

[0025] The following reference Figures 1 to 3 The technical solutions of some embodiments of this utility model are described below.

[0026] An embodiment of this utility model provides a stair mat 100, such as... Figures 1 to 3 As shown, from top to bottom, the stair mat 100 includes a carpet layer 110, a filling layer 120, and a self-adhesive bottom layer 130. The stair mat 100 body has a first end face 100a and a second end face 100b along its length. A plastic support member 121 is embedded in the middle of the filling layer 120. The plastic support member 121 is bendable and is used to allow the first end face 100a and the second end face 100b to form an angle α. Wherein, 0°≤α≤180°; when α is 0°, the stair mat 100 is in a flat state; when α is 180°, the stair mat 100 is in a folded state.

[0027] For example, when α is 0°, the stair mat 100 is fully unfolded and can be used as a floor mat in the living room or bedroom, or as a tabletop protective mat; or when the user does not want to use it on the stair steps, it can be removed and the stair mat 100 can be unfolded and used elsewhere.

[0028] For example, such as Figure 4 As shown, when α is 90°, it is suitable for the most common right-angle stair steps, and the support 121 is bent to fit the joint of the steps.

[0029] For example, such as Figure 5 As shown, when α is not a right angle, such as 80°, 100° or an arc shape, it is suitable for irregular staircases and curved furniture edges, such as the bottom of round tables and curved steps.

[0030] For example, when α is 180°, the stair mat 100 is folded, making it easy to store and transport.

[0031] To address the limitations of existing stair mats, such as bending constraints, limited application scenarios, poor flatness, and weak adhesion, this product optimizes the layered structure of the stair mat. The carpet layer 110, which comes into direct contact with the human body or objects, can be made of a high-friction material to solve the problems of slipping while walking and objects sliding. Simultaneously, as an aesthetic layer, the fabric texture or color can be used to beautify the environment, balancing practicality and decoration. The filling layer 120 serves two purposes: firstly, it provides a carrier for the flexible support component 121, preventing it from being exposed and worn; secondly, it cushions the impact of footsteps, reducing direct collision between the stair steps and feet, thus solving the problems of stiffness and poor comfort in existing products; and thirdly, it is self-adhesive. The bottom layer 130 directly adheres to the stairs or floor, enhancing adhesion and solving the problems of easy displacement and loose adhesion in existing products. The malleable support component 121 has the ability to actively bend and maintain its shape, rather than passively relying on creases. The bending direction can be flexibly adjusted according to needs, such as folding inward to fit the staircase facade or folding outward to fit the edge of furniture. This breaks through the limitation of existing products that can only bend at right angles in a fixed direction. The malleable support component 121 is located in the middle of the filling layer 120, preventing the support component from rusting and scratching people. It can also deform synchronously with the malleable support component 121 with the filling layer 120, further enhancing the shape retention ability of the stair mat 100.

[0032] In some embodiments of this application, both the body of the stair mat 100 and the body of the malleable support 121 have thickness; wherein, the distance from the center line of the thickness of the malleable support 121 to the side of the self-adhesive bottom layer 130 away from the filling layer 120 is 15%-25% of the thickness of the body of the stair mat 100.

[0033] The malleable support 121 near the bottom layer can deform synchronously with the angle of the step joint, which makes the bottom layer of the bent stair mat 100, namely the self-adhesive bottom layer 130, fit the surface to be bonded better. The 15%-25% position limit can ensure the flatness of the stair mat 100 during installation, avoid bulging, and improve the user experience.

[0034] In some embodiments of this application, the thickness of the stair mat 100 body is 5mm-15mm.

[0035] For example, the thickness error of each layer is controlled within ±0.2mm to ensure that the composite structure is flat and uniform in thickness, while ensuring that each layer deforms synchronously and without delamination when bending into an arc.

[0036] The overall thickness of 5mm-15mm can accommodate the malleable support 121 embedded in the middle of the filling layer 120 without making the stair mat 100 too thick and affecting its use. At the same time, the sufficient thickness can ensure that the malleable support 121 is completely wrapped by the filling layer 120, avoiding exposure and wear of the malleable support 121 and extending its service life. With the shaping ability of the malleable support 121, each layer can deform synchronously when bent, avoiding problems such as tearing of the outer fabric after bending due to the overall thinness. This ensures that the fabric has sufficient extensibility to follow the deformation, without wrinkles or curling edges, and has a high shape retention rate.

[0037] In some embodiments of this application, the thickness of the blanket layer 110 is 3mm-10mm; the material of the blanket layer 110 is a multi-layer textile fabric, which includes at least one of polyester fiber composite fabric and nylon composite fabric.

[0038] The carpet layer 110 has a thickness of 3mm-10mm, which can improve wear resistance and durability. The carpet can cushion the direct impact between the feet and the steps, reducing the risk of injury when falling. At the same time, the thick carpet can insulate the cold and hard touch of the step surface, significantly improving comfort when using it in winter, and is compatible with the bending requirements of the malleable support 121.

[0039] In some embodiments of this application, the thickness of the filling layer 120 is 1.5mm-4.5mm; the material of the filling layer 120 is non-woven fabric.

[0040] A 1.5mm-4.5mm thick filling layer 120 can completely wrap the malleable support 121 with a certain thickness, avoiding friction and wear caused by direct contact between the malleable support 121 and the carpet surface layer 110 or the self-adhesive bottom layer 130. At the same time, it prevents the malleable support 121 from shifting or deviating during use, ensuring that the support is always in the preset position, ensuring stable bending and shaping function, synchronous deformation of each layer without delamination, and enhancing the buffer transition between layers. The non-woven fabric has soft properties and can closely fit the surface of the malleable support 121 to achieve flexible wrapping, protecting the malleable support 121 from other interlayer structures. It is breathable and environmentally friendly, avoiding the problem of dampness and mold growth on the step surface caused by long-term laying of the stair mat 100. The non-woven fabric has low raw material cost, excellent processing performance, and is suitable for mass production.

[0041] In some embodiments of this application, the thickness of the malleable support 121 is 0.3mm-0.8mm; the material of the malleable support 121 is selected from at least one of aluminum, iron and copper.

[0042] For example, the malleable support 121 is a 1060 type aluminum sheet.

[0043] For example, the malleable support 121 is a T2 type copper sheet.

[0044] The thickness of the flexible support component 121 is limited to 0.3mm-0.8mm, which can precisely fit the thickness space of the filling layer 120 (1.5mm-4.5mm). It can be embedded inside the filling layer 120 for stable fixation without the filling layer 120 bulging due to excessive thickness, thus not affecting the overall flatness of the stair mat 100. This thickness can give the support component sufficient flexibility and support strength, easily achieving right-angle bends within the range of 0°-180° and arc bends with a radius of 5cm-30cm. The bending operation force is controlled at ≤12N, which can meet the user's need for easy angle adjustment. At the same time, it ensures support strength, with a shape retention rate of ≥95% after bending and a flatness error of ≤2mm / m, which meets the flatness requirements of home furnishings. The malleable support component 121 is made of at least one of aluminum, iron, and copper. Different materials can adapt to diverse usage scenarios. Aluminum has excellent ductility and elongation, with a maximum of 800 right-angle bends and 500 arc bends. It also has low density and light weight, preventing it from increasing the overall weight of the stair mat 100 and causing displacement during adhesion. It is also highly corrosion-resistant, making it suitable for humid environments or home scenarios requiring frequent adjustments to the bending angle. Iron is low-cost, with a yield strength of 180-220MPa and a support force of ≥3N / cm, meeting the basic support and cost control needs of the mass market in dry environments. Copper has the best overall performance, with an elongation of 45%-50%, and a maximum number of bends that is 1.6 times that of aluminum and 2 times that of iron. It is extremely corrosion-resistant, making it suitable for high-end commercial applications or scenarios requiring long-term low maintenance. All three materials can be stably bonded to the filling layer 120 and the carpet layer 110 using hot melt adhesive, preventing delamination between layers. The processing technology is mature, allowing for mass production through stamping and cutting, balancing functional practicality and market feasibility.

[0045] In some embodiments of this application, the thickness of the self-adhesive base layer 130 is 0.5mm-1.2mm; the material of the self-adhesive base layer 130 is TRE material.

[0046] The self-adhesive base layer 130, with a thickness of 0.5mm-1.2mm, has sufficient extensibility to adapt to deformation. The TRE material ensures initial adhesion, holding power, and extensibility. Even with repeated pasting, the adhesive strength can still maintain a certain initial strength, meeting the needs of the stair mat 100 in various usage scenarios such as stairs, floors, and tabletops. It can firmly fix the stair mat 100 and prevent it from shifting after being stepped on or slightly bumped. It is especially suitable for rounded stair steps or irregularly shaped furniture edges. The TRE material layer can extend with the shape of the carrier to achieve a seamless fit.

[0047] In some embodiments of this application, the width of the malleable support 121 is the same as the width of the stair mat 100 body; the length of the malleable support 121 is 3cm-10cm.

[0048] For example, when bent into an arc with a radius of 5cm-30cm, this length can ensure that the bending curvature of the support is continuous, causing the carpet layer 110 and the filling layer 120 to deform synchronously without any local disconnection.

[0049] The width of the malleable support 121 is the same as the width of the stair mat 100 body, which ensures that the support fully covers the width of the stair mat 100. The length of 3cm-10cm will not cause the stair mat 100 to become stiff and protruding when it is laid flat due to being too long, nor will it cause insufficient support range due to being too short.

[0050] In some embodiments of this application, the number of malleable support members 121 is one or more; wherein, the multiple malleable support members 121 are arranged parallel to each other along the length direction of the stair mat 100 body.

[0051] The number of malleable support members 121 is set to one or more, which can flexibly adapt to stair mats 100 of different widths.

[0052] In some embodiments of this application, the stair mat 100 further includes a release film, which is disposed on the side of the self-adhesive bottom layer 130 away from the filling layer 120; the carpet layer 110, the filling layer 120, the plastic support member 121 and the self-adhesive bottom layer 130 are bonded together by hot melt adhesive.

[0053] For example, the hot melt adhesive coating amount is 15g / m 2 -20g / m 2 The composite pressure is 0.4MPa-0.6MPa, and the coating temperature is 130℃-160℃. The peel strength between the metal sheet and the non-woven fabric / carpet surface is guaranteed to be ≥8N / 25mm, conforming to the GB / T2790-1995 standard for adhesives 180° peel strength test. Due to the increased overall thickness and the need for curved bending, the peel strength requirement is increased, and when the curved bending radius is ≥5cm, there is no delamination of the composite layer.

[0054] The release film on the stair mat 100, located on the side of the self-adhesive base layer 130 away from the filler layer 120, completely covers the adhesive surface of the self-adhesive base layer 130 during transportation, storage, and unused periods. This prevents adhesion loss due to dust and impurities, and also prevents the self-adhesive base layer 130 from sticking to packaging or other items, ensuring good adhesion during use. Simultaneously, the release film can be easily peeled off without leaving adhesive residue or damaging the structure of the self-adhesive base layer 130. The hot melt adhesive lamination process ensures a tight bond between the three layers, preventing delamination and ensuring synchronized deformation of each layer. Furthermore, the hot melt adhesive is a flexible layer, preventing the stair mat 100 from becoming stiff due to lamination; the bending force remains ≤12N, balancing structural stability and usability. The mature hot melt adhesive lamination process allows for mass production without special equipment, meeting the needs of industrial processing.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects.
