Description

Technical Field

[0001] This utility model relates to the field of mattress technology, and in particular to a spliced ​​sponge pad and mattress. Background Technology

[0002] Mattresses are an essential bedding item in modern life, and their structure is mostly a single piece of foam. To improve elasticity and support for the body, some mattresses incorporate internal springs for additional support. However, while modern mattresses have improved in terms of support, many traditional mattresses still suffer from poor body shape and comfort. This is because these mattresses typically use a uniform firmness layer, failing to provide personalized support for different parts of the body. This results in some areas experiencing excessive pressure, and if the elasticity and firmness are unsuitable, it's difficult to provide sufficient support for areas like the lower back and shoulders during sleep, easily causing aches and pains in these areas and affecting sleep quality. Therefore, an important goal of mattress design is to improve its conformity to the body shape, better adapting to different sleeping positions, reducing pressure points, and providing a more comfortable sleep experience. Utility Model Content

[0003] In order to address the shortcomings of existing mattresses in terms of poor comfort, this utility model proposes a spliced ​​sponge pad and mattress.

[0004] The technical solution adopted by this utility model is a spliced ​​sponge pad, which includes a main sponge. The upper surface of the main sponge has, from one end to the other along its length, a first support area, a second support area, a third support area, a fourth support area, a fifth support area, a sixth support area, and a seventh support area, corresponding to the human head, shoulder, waist, hip, thigh, calf, and foot. The second, fourth, and sixth support areas are through grooves formed on the surface of the main sponge. The through grooves are filled with a filler with a hardness less than that of the main sponge, and the surfaces of the third and fifth support areas are wavy.

[0005] Preferably, the lower surface of the main sponge is further provided with several irregularly shaped through grooves.

[0006] Preferably, the irregularly shaped through groove is disposed on the lower surface of the main body sponge relative to the second support area, the third support area, the fifth support area and the sixth support area.

[0007] Preferably, the irregular through-slot includes a slot opening located on the lower surface of the main sponge and a pair of slot walls, each slot wall having a wavy, uneven structure.

[0008] Preferably, the filling material is a spring pad and / or a sponge with openings.

[0009] Preferably, the lengths of the first and seventh support areas are 250 mm, the lengths of the second and sixth support areas are 300 mm, the lengths of the third and fifth support areas are 270 mm, and the length of the fourth support area is 360 mm.

[0010] This utility model also proposes a mattress including the aforementioned sponge pad, wherein the sponge pad is the support layer of the mattress, and the mattress further includes a comfort layer disposed on the support layer.

[0011] Furthermore, the comfort layer includes a soft sponge layer and a memory foam layer.

[0012] Compared with existing technologies, the main body sponge of this invention uses different zoned materials and support methods in different areas, which enables it to provide precise support according to the needs of different parts of the body, improving overall comfort. By adopting a wave-shaped sponge and soft filling design, the sponge can better adapt to the curves of the shoulders, waist, hips and other parts, reducing the formation of pressure points, providing users with a softer and more comfortable sleep experience, providing balanced and comfortable support, optimizing the sleep state of various parts of the body, reducing physical fatigue and helping to improve sleep quality.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] This utility model discloses a spliced ​​sponge pad, see attached document. Figure 1 , 2 As shown, the sponge pad is used as part of a mattress. The sponge pad proposed in this utility model mainly includes a main sponge 1. The main sponge 1 uses high-density sponge to meet the requirements of its use as a mattress support layer. The upper surface of the main sponge 1 is divided into seven sections along its length: a first support area 2, a second support area 3, a third support area 4, a fourth support area 5, a fifth support area 6, a sixth support area 7, and a seventh support area 8. The first support area 2 corresponds to the head area, the second support area 3 corresponds to the shoulder area, the third support area 4 corresponds to the waist area, the fourth support area 5 corresponds to the hip area, the fifth support area 6 corresponds to the thigh area, the sixth support area 7 corresponds to the calf area, and the seventh support area 8 corresponds to the foot area. Furthermore, the second, fourth, and sixth support areas 7 are modified by creating through grooves 9 and replacing the filling material 10 within the through grooves 9 to change the support strength of these areas. The upper surfaces of the third and fifth support areas 6 are also designed with a wavy shape.

[0022] Preferably, the present invention further provides several irregularly shaped through grooves 11 on the lower surface of the main body sponge 1. The irregularly shaped through grooves 11 penetrate both sides of the width direction of the main body sponge 1. These irregularly shaped through grooves 11 have a certain deformation space, which makes the bending deformation performance of the main body sponge 1 better and prevents the main body sponge 1 from tearing during bending. In addition, the present invention provides irregularly shaped through grooves 11 on the lower surface of the main body sponge 1 relative to the second support area 3, the third support area 4, the fifth support area 6 and the sixth support area 7. These positions correspond to the shoulder, waist, thigh and calf parts respectively. The irregularly shaped through grooves 11 can appropriately reduce the load on these positions, which can make the middle of the body sink downward when the person lies flat or on their side. As for the buttocks area (corresponding to the fourth support position), due to its greater thickness, it needs more uniform support and is not easy to sink. Therefore, this part of the area only provides more uniform support by adapting the filling material 10, and no irregularly shaped through grooves 11 are provided to avoid insufficient support of the main body sponge 1 and the problem of excessive sinking.

[0023] Furthermore, in a specific embodiment, in the cross-sectional view direction of the irregular through groove 11 in this utility model, the lower end of the irregular through groove 11 is located on the lower surface of the main body sponge 1. Each irregular through groove 11 includes a pair of groove walls 12. The surface of each groove wall 12 is designed with a wave-shaped concave-convex structure. The wave-shaped groove wall 12 design enables the main body sponge 1 to improve the bending performance of these irregular through grooves 11 and the elasticity in the thickness direction, thereby providing good support for the user.

[0024] Preferably, based on standard human body dimensions, the present invention uses a first support area 2 and a seventh support area 8 with a length of 250 mm, a second support area 3 and a sixth support area 7 with a length of 300 mm, a third support area 4 and a fifth support area 6 with a length of 270 mm, and a fourth support area 5 with a length of 360 mm.

[0025] This utility model also proposes a mattress based on the above-mentioned spliced ​​sponge pad, such as... Figure 3 The mattress uses a 200mm thick sponge pad as the overall support layer. The filling material 10 in the through groove 9 is 90mm thick. The sponge pad uses hard sponge to replace the spring support layer. On the support layer, there is also a 2cm thick soft sponge layer 13 and a memory foam layer 14. The soft sponge layer 13 provides comfortable surface support, while the memory foam layer 14 provides precise support based on body shape. This layered design provides both intuitive comfort and comprehensive support for the body at a deeper level, ensuring comfort even when lying in bed for a long time. Whether lying on your back, side, or stomach, the base can be reasonably adjusted according to different pressure requirements.

[0026] Preferably, the filling material 10 can be spring pads and / or sponges with openings; these filling materials 10 can provide softer support and have good breathability.

[0027] Combined with appendix Figure 4 , 5 As shown, the filling material 10 of this utility model includes a main body 101 and a breathable groove 102 disposed on the surface of the main body 101. The main body 101 is made of a material with good elasticity and support, such as high-density sponge or high-elasticity polyurethane foam. The function of the main body 101 is to provide basic support for the mattress, while maintaining the stability and durability of the mattress. The elasticity and hardness of the main body can be adjusted according to different design requirements, thereby ensuring that the mattress can meet the support needs of different parts.

[0028] like Figure 4The three filling embodiments shown depict numerous block-shaped protrusions 103 on the surface of the main body 101. These protrusions 103 form a grid-like ventilation channel, and their size and density can be adjusted. By adjusting the size and density of the protrusions 103, the support firmness and breathability of the filling surface can be regulated. The size, shape, and arrangement density of the protrusions 103 can all be adjusted, thereby achieving mattress firmness adjustment and breathability optimization. Specifically, by adjusting the size and density of the protrusions 103, the surface firmness and comfort of the filling can be precisely controlled. Larger protrusions 103 provide stronger support, suitable for areas requiring firmer support; while smaller protrusions provide softer support, suitable for areas requiring softer support. Furthermore, a higher arrangement density of the protrusions 103 results in stronger support, while a lower density results in a softer surface, conforming to the body's curves. These block-shaped protrusions 103 are arranged in a grid-like ventilation channel 102, meaning that each block-shaped protrusion 103 forms a grid-like gap structure with its adjacent protrusions. This structure not only facilitates air circulation and improves the breathability of the mattress, but also disperses local pressure through the grid-like gaps, reducing discomfort caused by prolonged pressure, especially in areas with high weight-bearing capacity such as the user's shoulders and hips. Due to the grid-like ventilation channels 102 between the block-shaped protrusions 103, multiple ventilation channels are formed on the mattress surface. These ventilation channels 102 help keep the mattress dry by promoting airflow, preventing sweat buildup, and improving the mattress's comfort and hygiene.

[0029] This invention allows the firmness of the block protrusions 103 to be adjusted by changing their size and density to meet different user needs. Larger protrusions are suitable for areas requiring greater firmness (such as the waist and hips), while smaller protrusions are suitable for areas requiring softer support (such as the shoulders and legs). This design allows the mattress to have precise firmness zones, improving overall comfort. By adjusting the density and arrangement of the block protrusions 103, the mattress can provide more personalized support. For example, increasing the density of the protrusions in areas requiring greater support (such as the hips) can enhance the support in these areas, providing more even support and improving the wrapping of the hips, preventing excessive sinking; while in areas requiring less support (such as the shoulders and legs), the density can be appropriately reduced to provide a softer comfort. The grid-shaped ventilation channels 102 allow for a more even distribution of pressure on the filling surface, preventing discomfort caused by excessive pressure in localized areas. This even pressure distribution can effectively reduce pressure caused by prolonged sleep, improving sleep quality.

[0030] Furthermore, the design of the block protrusions 103 can be flexibly adjusted according to actual needs. For example, the support effect can be further optimized by selecting different types of sponges, foams, or other elastic materials; at the same time, the spacing, shape, and size of the block protrusions 103 can be customized according to ergonomic requirements to meet the comfort needs of different users. Through this customized design, the mattress's comfort, support, and breathability are comprehensively optimized.

[0031] Furthermore, such as Figure 5 As shown, the main body of the filling 10 consists of three main parts: a base pad 104, a shell 105, and a spring layer 106. The base pad 104, located at the bottom of the filling, primarily supports the spring layer 106, ensuring it is not subjected to external pressure or deformation during use. The support function of the base pad 104 helps maintain the overall shape and stability of the mattress, preventing the spring layer from sinking or shifting after long-term use. Through the support of the base pad, the mattress can maintain the elasticity and efficient support performance of the spring layer for a long time, extending the mattress's lifespan. The lower part of the shell 105 includes a frame 107, which not only provides an external protective structure for the filling, preventing internal components from being damaged by external physical forces, but also enhances the structural integrity of the mattress. The frame fixes the base pad and integrates it with the spring layer, ensuring the mattress's stability. The overall integrity of the shell in both appearance and function effectively prevents materials from loosening, falling off, or deforming, improving the long-term stability and durability of the mattress. The spring layer 106 is located within the cavity formed by the base pad 104 and the shell 105. The presence of the spring layer 106 provides strong elastic support to the mattress, contributing to improved overall comfort. Through the stretching and compression of the springs, the spring layer 106 automatically adjusts the mattress firmness according to the user's weight and sleeping position, ensuring even support for every part. The cavity design between the base pad 104, shell 105, and spring layer 106 allows the spring layers to work independently and flexibly, improving the mattress's adaptability. The cavity space not only ensures the free movement of the spring layers but also reduces localized deformation under pressure, preventing the mattress surface from sagging due to spring loss of elasticity. Simultaneously, the cavity design allows air to circulate between the spring layer and the base pad, further improving the mattress's breathability and keeping it dry and comfortable.

[0032] In this invention, the outer shell, bottom shell, and frame are all made of sponge material. These materials not only enhance the mattress's comfort but also protect the internal spring layers and other structures. The sponge structure contributes to the mattress's overall durability. Particularly in the frame and bottom shell design, the sponge material effectively absorbs external forces, reducing the impact of external shocks and friction on the spring layers and other structures, thus extending the lifespan of the filling material 10. As an external protective layer for the spring layers, the outer shell and bottom shell reduce compression, displacement, and damage to the spring layers during prolonged use, preventing the mattress from losing comfort and support due to structural changes. The sponge frame provides better edge support, preventing edge sagging or loosening after extended use. When the user sits or moves around on the edge of the mattress, the sponge frame provides effective support, ensuring the entire mattress maintains a stable shape and preventing discomfort caused by unstable edges.

[0033] In summary, by combining the base, shell, and spring layers, the filling material 10 achieves a balance in support, comfort, breathability, and durability, providing a more scientific, flexible, and comfortable sleeping environment. The support of the base, the protection of the shell, and the elasticity of the spring layers ensure that the mattress not only performs excellently in short-term use but also maintains efficient support and comfort over long-term use, significantly improving sleep quality and extending the mattress's lifespan. The good elasticity and adaptability of the foam material provide even support while maintaining a soft and comfortable experience, reducing pressure caused by uneven firmness. Furthermore, the breathability of the foam effectively wicks away moisture and allows for ventilation, keeping the mattress dry and reducing the growth of bacteria and odors, ensuring hygiene and suitability for long-term use. Simultaneously, the compressive strength of the foam material ensures the mattress maintains long-term stability, preventing structural changes due to excessive pressure, especially protecting the internal spring and support layers.

[0034] The advantages of this invention are as follows: The main sponge 1 provides moderate support for the head and feet, which is conducive to foot relaxation. The shoulders, hips, and calves rely on the support of the replacement filling material 10, which is often subjected to greater pressure. To solve this problem, this design uses a filling material that is softer than the sponge. The softness of the filling material 10 effectively reduces the pressure on the shoulders, ensuring that the shoulders receive more comfortable support. At the same time, it avoids numbness or incoordination in the shoulders due to excessive support. The hip design also uses a soft filling material 10, which can better adapt to the curve of the hips, allowing the hip area to sink appropriately and reducing unevenness caused by long-term contact. Moreover, the softness of the filling material 10 helps to disperse pressure and avoid the feeling of crowding in the hips. The calves are also supported by a softer filling material 10. These soft materials can effectively disperse small pressures, creating a natural and relaxed state and avoiding wear and tear and discontinuity. The lumbar support uses a wave-shaped foam surface. This design provides different levels of support in different areas, better supporting the natural curve of the lower back. The wave-shaped structure allows the foam to provide more even and comfortable support according to the curve of the lower back, helping to maintain the natural position of the spine and reducing pressure on the lower back. The thigh area also uses a wave-shaped foam design. This design distributes support pressure according to the natural shape of the body, further enhancing sleep comfort, especially during long sleeps or rests, helping to reduce fatigue.

[0035] This invention utilizes different materials and support methods in different areas. By combining various filling materials, a wavy main sponge surface design, and irregularly shaped grooves at the bottom of the main sponge, the sponge pad is divided into multiple areas of varying firmness. This allows for precise support tailored to the needs of different parts of the body, enhancing overall comfort. The wavy sponge and soft filling design enable the sponge to better adapt to the curves of the shoulders, waist, and other areas, reducing pressure points and providing users with a softer, more comfortable sleep experience. It offers balanced and comfortable support, optimizes the sleep state of various body parts, reduces fatigue, and helps improve sleep quality.
