Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically, it relates to a rollable high-hardness foam mattress. Background Technology

[0002] In modern home life, mattresses are a key component for people's sleep and rest, and their performance and ease of use are of great concern. Traditional high-firm foam mattresses occupy a certain market share, but they have obvious limitations in many aspects. Traditional high-firm foam mattresses are usually constructed from a single piece of high-firm foam. Due to their relatively rigid overall structure and lack of sufficient flexibility, they cannot be effectively folded or rolled up, taking up a lot of space. This not only increases transportation costs, but also requires a large storage space for home storage or store inventory management. In addition, in some narrow stairwells, elevator lobbies, or corridors, it is difficult to move them smoothly, and may even damage the mattress due to forced movement, causing great inconvenience to consumers. Therefore, developing a rollable high-firm foam mattress is of great practical significance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rollable high-hardness sponge mattress that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a rollable high-hardness foam mattress, comprising: a high-hardness foam layer, wherein the high-hardness foam layer includes two high-hardness foam pads and one medium-hardness foam pad, the two high-hardness foam pads are symmetrically connected on the upper and lower surfaces of the medium-hardness foam pad, and the high-hardness foam pads and the medium-hardness foam pads are bonded together with environmentally friendly adhesive; the sides of the high-hardness foam pads and the medium-hardness foam pads that are in contact are provided with equally spaced arc-shaped grooves, and air channels are formed between the arc-shaped grooves on the high-hardness foam pads and the adjacent arc-shaped grooves on the medium-hardness foam pads; an elastic connecting layer is disposed on the upper and lower surfaces of the high-hardness foam layer; and a flexible wrapping layer is used to wrap the high-hardness foam layer and the elastic connecting layer therein by sewing.

[0005] To facilitate the mattress being rolled into a compact cylindrical shape, the arc-shaped grooves on the high-hardness and medium-hardness foam pads are designed in a straight line.

[0006] To facilitate increasing the contact area between the high-hardness and medium-hardness sponge pads and the air, the arc-shaped grooves on the high-hardness and medium-hardness sponge pads are further designed with an S-shaped curve.

[0007] To further enhance the elasticity and comfort of the mattress, the elastic connecting layer is further comprising an elastic fiber web with rubber particles distributed at the nodes of the elastic fiber web.

[0008] To further enhance the bonding strength between the elastic connecting layer and the high-hardness sponge layer, the elastic connecting layer and the high-hardness sponge layer are connected by heat fusion.

[0009] To further improve the performance of the flexible wrapping layer, the flexible wrapping layer is made of a high-strength, wear-resistant fabric material.

[0010] To further prevent dust from entering the mattress through the seams, the seams of the flexible wrapping layer are sealed with environmentally friendly sealant.

[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: Compared with traditional high-hardness sponge mattresses, when the mattress needs to be moved, transported or stored, it can be rolled into a cylindrical shape according to the prescribed rolling method, which greatly reduces the space occupied, facilitates transportation and storage, and effectively improves the practicality and convenience of the mattress.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Example 1:

[0021] Reference Figures 1-4 A rollable high-hardness foam mattress includes: a high-hardness foam layer 1, comprising two high-hardness foam pads 101 and a medium-hardness foam pad 102, the two high-hardness foam pads 101 being symmetrically connected to the upper and lower surfaces of the medium-hardness foam pad 102, and the high-hardness foam pads 101 and the medium-hardness foam pad 102 being bonded together with environmentally friendly adhesive; arbitrarily spaced arc-shaped grooves 103 are provided on the surfaces of the high-hardness foam pads 101 and the medium-hardness foam pad 102 that are in contact with each other, forming air channels between the arc-shaped grooves 103 on the high-hardness foam pads 101 and the adjacent arc-shaped grooves 103 on the medium-hardness foam pad 102; an elastic connecting layer 2, disposed on the upper and lower surfaces of the high-hardness foam layer 1; and a flexible wrapping layer 3, which wraps the high-hardness foam layer 1 and the elastic connecting layer 2 within the mattress by stitching.

[0022] By employing a unique layered structure design for the high-hardness sponge layer 1, its interior is composed of multiple layers of sponge pads with different hardnesses. For example, the bottom layer uses a high-hardness sponge pad 101 to provide a solid support base, the middle layer is a medium-hardness sponge pad 102 to increase elastic cushioning, and the top layer is covered with another high-hardness sponge pad 101 to ensure the flatness and hardness of the surface. These sponge layers are bonded together with environmentally friendly adhesive, and arc-shaped grooves 103 are set on the sponge pads to form air channels between adjacent sponge pad layers, which not only enhances the breathability of the mattress, but also improves its flexibility to a certain extent, making it easier for subsequent rolling operations.

[0023] Due to the special layered structure of the high-hardness sponge layer 1 and the presence of the elastic connecting layer 2, the mattress can undergo moderate deformation when subjected to external force. During the rolling process, applying a certain rolling force along the length of the mattress allows the entire mattress to gradually roll into a compact cylindrical shape. For example, for a standard-sized mattress of 1.8 meters × 2 meters, its diameter can be controlled between 60 and 80 centimeters after rolling, greatly reducing the space occupied and facilitating transportation and storage.

[0024] After multiple rolling and unrolling tests, the mattress maintained its high firmness and overall structural integrity. The bonding structure inside the high-firm sponge layer 1 and its connection with the elastic connecting layer 2 were not damaged during the rolling process, ensuring that the mattress could still provide stable support during use. After 50 rolling cycles, the mattress firmness change rate was less than 3%, and the elasticity recovery rate was still over 95%, ensuring that the user's sleep experience was not affected.

[0025] In terms of transportation, rolled-up mattresses can be easily placed in the trunk of small trucks, vans, or even cars, reducing the space requirements for transport vehicles, improving transportation efficiency, and reducing transportation costs. For example, some mattress products sold online can be delivered directly to consumers via express delivery, without relying on professional furniture transport vehicles like traditional mattresses.

[0026] In terms of storage, rolled-up mattresses can be easily stored, whether at the bottom of a wardrobe in the home, in a corner of an attic, or on a shelf in a furniture store, saving a lot of storage space and facilitating inventory management and home organization.

[0027] In the production of this rollable high-hardness foam mattress, foam pads of different hardness are first prepared according to design requirements, and then treated with arc-shaped grooves 103 and bonded to form an integral high-hardness foam layer 1. Then, the elastic connecting layer 2 is connected to the high-hardness foam layer 1. Finally, the prepared high-hardness foam layer 1 and elastic connecting layer 2 are sewn together with a flexible wrapping layer 3 to obtain the finished mattress. When in use, consumers can unfold the mattress and lay it on the bed for normal use as needed. If it needs to be moved, transported or stored, it can be rolled into a cylindrical shape according to the prescribed rolling method, which is convenient and quick, providing users with a novel and practical mattress product solution.

[0028] The rollable high-hardness foam mattress of this invention effectively solves the problem of traditional high-hardness foam mattresses being difficult to roll up through its innovative structural design. While improving the practicality and convenience of the mattress, it also provides a useful reference for product innovation and development in the furniture industry.

[0029] Example 2:

[0030] Reference Figure 3 It can be rolled up to form a high-hardness foam mattress, which is basically the same as in Example 1. However, the arc-shaped grooves 103 on the high-hardness foam pad 101 and the medium-hardness foam pad 102 are designed in a straight line.

[0031] By designing the arc-shaped groove 103 as... Figure 3The straight line shape shown not only ensures air circulation in the mattress, but also allows the medium-hardness foam pad 102 to better compress the high-hardness foam pad 101 when the mattress needs to be rolled up, in conjunction with the straight arc groove 103, so that the entire mattress can be better rolled into a compact cylindrical shape.

[0032] Example 3:

[0033] Reference Figure 4 It can be rolled up to form a high-hardness foam mattress, which is basically the same as in Example 1. However, the arc grooves 103 on the high-hardness foam pad 101 and the medium-hardness foam pad 102 are designed with an S-shaped curve.

[0034] By designing the arc-shaped groove 103 as... Figure 4 The curved shape shown increases the contact area between the high-hardness sponge pad 101, the medium-hardness sponge pad 102 and the air when air flows in the air channel, thereby further enhancing the breathability of the mattress.

[0035] Example 4:

[0036] Reference Figures 1-4 It can be rolled up to wrap a high-hardness sponge mattress, which is basically the same as in Example 2 or 3. Furthermore, the elastic connecting layer 2 is an elastic fiber web, and rubber particles are distributed at the nodes of the elastic fiber web.

[0037] The elastic connecting layer 2 and the high-hardness sponge layer 1 are connected by heat fusion.

[0038] The elastic connecting layer 2 is composed of a mixture of elastic fiber web and rubber particles. The elastic fiber web provides the basic connecting framework, while the rubber particles are distributed at the nodes of the fiber web. When the mattress is subjected to pressure, the rubber particles can deform and absorb some energy, further enhancing the elasticity and comfort of the mattress. At the same time, the elastic connecting layer 2 is connected to the high-hardness sponge layer 1 by heat fusion, ensuring the firmness of the connection. Moreover, this connection method will not have a significant impact on the structure and performance of the sponge layer, which is conducive to maintaining the overall stability of the mattress.

[0039] Example 5:

[0040] Reference Figures 1-4 It can be rolled up to form a high-hardness sponge mattress, which is basically the same as in Example 4, but further: the flexible wrapping layer 3 is made of a high-strength, wear-resistant fabric material.

[0041] The seams of the flexible wrapping layer 3 are sealed with environmentally friendly sealant.

[0042] The outermost layer of the mattress is a flexible wrapping layer 3, made of high-strength, wear-resistant, and flexible fabric material, such as a blend of polyester fiber and spandex. The polyester fiber ensures the strength and wear resistance of the fabric, while the spandex gives it good elasticity and flexibility. The flexible wrapping layer 3 wraps the high-hardness sponge layer 1 and the elastic connecting layer 2 inside by sewing. The seams are treated with special sealant to prevent dust from entering the mattress. At the same time, the surface of the flexible wrapping layer 3 can be pre-treated with antibacterial and anti-mite agents to improve the hygiene performance of the mattress and provide users with a healthy sleep environment.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
