[0032] Example 1:
[0033] This embodiment provides an adjustable firmness mattress. By modularly replacing the internal structure of the mattress, it solves the problems of convenience, flexibility, and zoned adjustment of firmness, and also addresses the issues of internal module displacement and warping. It should be noted that the firmness referred to in this embodiment refers to the relative softness of the mattress's support. Figures 1-4As shown, the mattress includes, from top to bottom, a top quilted layer 30, an adjustable support layer 10, an elastic support layer 20, and a bottom quilted layer 40. The adjustable support layer 10 includes a lower padding layer 1, an edge structure 2, a fastening structure, and multiple cube modules 3 with varying firmness. The lower padding layer 1 is positioned above the elastic support layer 20. The edge structure 2 is arranged along the circumference of the lower padding layer 1 and encloses it to form an installation groove 101. Multiple cube modules 3 are detachably installed within the installation groove 101. At least a portion of the top quilted layer 30 is detachably connected to the adjustable support layer 10 to selectively open and close the installation groove 101. Multiple cube modules 3 with different firmnesses can be selectively installed in the installation groove 101 to adjust the support firmness of multiple areas. The elastic support layer 20 is an independent pocket spring mattress with multiple spring support components inside. The spring support components are independent pocket springs. The adjustable support layer 10 works in conjunction with the elastic support layer 20 to provide users with an elastic, soft, and comfortable support experience.
[0034] It should be noted that the mattress provided in this embodiment is actually a modular mattress. It is formed by modularly splicing multiple Rubik's Cube 3 modules to form a support layer with adjustable support strength. The splicing technology realizes dynamic support adaptation in different areas of the mattress. Since its modular splicing structure is similar to the single-sided structure of a Rubik's Cube, the mattress is regarded as a Rubik's Cube structure, and the adjustable support module is named Rubik's Cube Module 3.
[0035] Furthermore, such as Figures 1-4 As shown, the adjustable support layer 10 also includes a fastening structure. The Rubik's Cube module 3 is installed in the mounting groove 101 through the fastening structure. The fastening structure can limit the position and orientation of the Rubik's Cube module 3.
[0036] Specifically, the modular adjustable mattress provided in this embodiment has an adjustable support layer 10 with adjustable firmness between the elastic support layer 20 and the top quilted layer 30. The adjustable support layer 10 achieves overall and zoned adjustment of the support firmness by selectively installing multiple cube modules 3 with different firmnesses. At least a portion of the top quilted layer 30 is detachably connected to the adjustable support layer 10. The user can remove this structure to open the mounting groove 101, thereby replacing the cube module 3 in the mounting groove 101 to achieve firmness adjustment. Furthermore, the cube module 3 is fixed in the mounting groove 101 by a fastening structure, maintaining the position and orientation of the cube module 3, preventing it from tilting or shifting under pressure, ensuring support stability, and improving the user experience.
[0037] For example, the top quilted layer 30 and the surrounding structure 2 are connected and fixed by a first zipper 4. One part of the first zipper 4 extends along the outer periphery of the top surface of the surrounding structure 2 and is sewn to the surrounding structure 2. The other part of the first zipper 4 extends along the outer periphery of the bottom surface of the top quilted layer 30 and is also sewn to the top quilted layer 30. The starting and ending points of the first zipper 4 are both located at the headboard of the modularly adjustable mattress for user operation and to easily conceal the first zipper 4 through the headboard, improving aesthetics.
[0038] For example, such as Figure 1 As shown, the top of the cube module 3 is flush with the top of the edge structure 2. The fastening structure uses a limiting pad 5, which is located on the top of the mounting groove 101. The limiting pad 54 is used to cover the cube module 33 below, thereby limiting the position of the cube module 33 in the vertical direction and ensuring that the cube module 33 in the mounting groove 101 does not shift or tilt during use. At least a portion of the limiting pad 5 is detachably connected to the top of the edge structure 2 to selectively open and close the mounting groove 101. The limiting pad 5 can be made of breathable mesh fabric, providing soft support, and has multiple ventilation holes to improve the breathability of the cube mattress. In some embodiments, the top of the cube module 3 may also be slightly higher than the top of the edge structure 2. The limiting pad 5 is a flexible structure that can also cover the top of the cube module 3 to limit its position in the vertical direction through slight deformation.
[0039] For example, at least three sides of the limiting pad 5 are connected to the top surface of the surrounding structure 2 via a zipper or snap-fit structure. In this embodiment, as... Figure 1 As shown, the limiting pad 5 is connected to the top surface of the surrounding structure 2 via a second zipper 6. Specifically, one part of the second zipper 6 extends along the inner periphery of the top surface of the surrounding structure 2 and is fixed to the surrounding structure 2 by sewing, while the other part of the second zipper 6 extends along the outer periphery of the limiting pad 5 and is fixed to the side edge of the limiting pad 5 by sewing. At least three of the four sides of the limiting pad 54 are connected to the surrounding structure 2 via the second zipper 6 to ensure that the user can easily take out and put in the Rubik's Cube module 3.
[0040] For example, the Rubik's Cube module 3 includes a Rubik's Cube inner liner 31 and a Rubik's Cube cover 32. The Rubik's Cube cover 32 is fitted over the Rubik's Cube inner liner 31 and has a cover opening 321 and a sealing element 33 for selectively opening and closing the cover opening 321. Specifically, the Rubik's Cube module 3 wraps the Rubik's Cube inner liner 31 with the Rubik's Cube cover 32, and the cover opening 321 is left on the Rubik's Cube cover 32. The cover opening 321 can be selectively opened and closed by the sealing element 33. On the one hand, by wrapping the Rubik's Cube inner liner 31 with the Rubik's Cube cover 32, it serves to protect the Rubik's Cube inner liner 31 and improve the aesthetics after the mattress is opened. On the other hand, the closable design of the Rubik's Cube cover 32 allows the user to replace the Rubik's Cube inner liner 31 with different firmness or damage, as well as replace the dirty or damaged Rubik's Cube cover 32. The Rubik's Cube cover 32 and the Rubik's Cube inner liner 31 can be replaced separately, reducing replacement costs.
[0041] Optional, such as Figure 2 and Figure 3 As shown, the sealing element 33 is a sealing strip. After heating, the sealing strip can adhere to or separate from the sides of the cover opening 321 to open and close the cover opening 321. Specifically, the sealing strip is made of heat-sealing fabric, with a length of 75cm and a width of 6.5cm. It is ironed onto the sealing strip at a temperature of 100-110℃ (preferably 100℃) to seal the cover opening 321. If the inner lining 31 inside the cover 32 needs to be replaced, the sealing strip can be torn open multiple times and then ironed back onto the sealing strip to seal the cover opening 321. Furthermore, using a sealing strip for sealing prevents an increase in the thickness of the sealed area of the cover opening 321, thus avoiding unevenness in the overall structure of the adjustable support layer 10 and improving the flatness of the mattress.
[0042] Preferably, one side of the sealing strip is fixed to the Rubik's Cube cover 32 by sewing to prevent the sealing strip from being lost after being torn, and to eliminate the need to re-align the sealing strip when resealing.
[0043] In another embodiment, such as Figure 4 As shown, the sealing element 33 can also be a sealing zipper. The sealing zipper is located on the two long sides of the fabric opening 321, and the fabric opening 321 is opened and closed by the sealing zipper. Preferably, the sealing zipper is set as an invisible zipper structure to avoid the sealing zipper causing an increase in the thickness of the sealed area of the fabric opening 321.
[0044] For example, such as Figures 1-4As shown, the inner core 31 of the mattress is designed with a cube-shaped structure. Multiple cube modules 3 in the adjustable support layer 10 are arranged in a matrix, with at least two columns of cube modules 3 along the width of the mattress and multiple rows along the length. In this embodiment, the adjustable support layer 10 has two columns of cube modules 3 along the width of the mattress, each corresponding to the usage area of two users. By replacing the cube modules 3 in the corresponding area, independent adjustment of the support firmness can be achieved between different users, avoiding mutual interference. The adjustable support layer 10 has multiple rows of cube modules 3 along the length of the mattress, allowing users to flexibly replace the cube modules 3 according to different body parts and heights to adapt to the support firmness needs of users with different body parts and heights.
[0045] For example, such as Figure 1 As shown, when the cube module 3 is installed above the spring support layer 20, the width of the cube inner core 31 is set along the length of the mattress. The width of the cube inner core 31 of the cube module 3 with different firmness is different. For example, the widths of the cube inner core 31 supporting the soft, medium and hard firmness are D1, D2 and D3 respectively. Alternatively, the colors of the cube cloth cover 32 of the cube module 3 with different firmness are different. For example, the colors of the cube cloth cover 32 supporting the soft, medium and hard firmness are red, blue and yellow respectively, which allows users to easily identify and distinguish the cube inner core 31 with different firmness.
[0046] For example, the inner lining of the Rubik's Cube 31 is made of bio-based material, specifically bio-based cotton or soybean-based polyurethane foam. The material is natural and environmentally friendly, and has the advantage of low allergenicity.
[0047] For example, the Rubik's Cube module 3 has three support hardness levels: soft, medium, and hard. Correspondingly, the Rubik's Cube inner liner 31 also has three support hardness levels: soft, medium, and hard. By adjusting the manufacturing process, Rubik's Cube inner liner 31 with different support hardness levels can be obtained. For example, by adjusting the ratio of polyol to isocyanate and adding functional additives, the hardness of soybean-based polyurethane foam can be precisely controlled. Such process adjustments are all existing technologies and will not be elaborated here.
[0048] For example, the material of the Rubik's Cube cloth cover 32 is 3D mesh fabric, which is a three-dimensional mesh material made of high-density polyester fiber through three-dimensional weaving technology. It has the characteristics of being washable, highly breathable, highly elastic, and pressure resistant.
[0049] Example 2:
[0050] like Figure 5 and Figure 6 As shown, based on Embodiment 1, this embodiment provides another modularly adjustable mattress, which differs from Embodiment 1 in that:
[0051] The adjustable support layer 10 does not include the limiting pad layer 5. The fastening structure uses an elastic band 7, which is located in the mounting groove 101. The elastic band 7 is composed of elastic elements such as elastic rope. The elastic band 7 is elastic and can press the Rubik's Cube module 3 below it with elastic force, thereby limiting the Rubik's Cube module 3 to a preset position in the mounting groove 101, preventing the Rubik's Cube module 3 from shifting or tilting when subjected to force. Users can release the Rubik's Cube module 3 below the elastic band 7 by pulling up or removing the elastic band 7, so as to easily pick up and put down the Rubik's Cube module 3.
[0052] Furthermore, at least two elastic bands 7 are provided, with their two ends connected to the two sides of the edge structure 2 corresponding to the headboard and footboard, respectively. At least two elastic bands 7 are spaced apart along the width of the mattress to reliably and comprehensively fix the cube modules 3 in a matrix distribution within the mounting groove 101. Specifically, four elastic bands 7 are spaced apart along the width of the mattress, each elastic band 7 being 180cm long and 5cm wide. Please refer to [link / reference]. Figure 6 From left to right, the first elastic band 7 is 25cm away from the left inner wall of the mounting groove 101, the second elastic band 7 is 25cm away from the first elastic band 7, the third elastic band 7 is 50cm away from the second elastic band 7, and the fourth elastic band 7 is 25cm away from the third elastic band 7.
[0053] Example 3:
[0054] like Figure 7 and Figure 8 As shown, based on Embodiment 1, this embodiment provides another modularly adjustable mattress, which differs from Embodiment 1 in that:
[0055] The adjustable support layer 10 does not include the limiting pad layer 5. The fastening structure uses a Velcro assembly, which includes a Velcro hook surface 81 and a Velcro loop surface 82 or a fleece surface on the upper surface of the lower pad layer 1. The cube module 3 is fixed to the upper surface of the lower pad layer 1 via the Velcro hook surface 81. In this embodiment, the bottom surface of the cube module 3 has two Velcro hook surfaces 81 extending along its length. The upper surface of the lower pad layer 1 is covered with a single piece of Velcro loop surface 82. The cube module 3 can be quickly and reliably detachably fixed to the lower pad layer 1 via the Velcro assembly, which is very convenient for users to install and remove. By setting a single piece of Velcro loop surface 82, the number of structural layers can be reduced, mitigating the impact of the increased gap between the cube module 3 and the lower pad layer 1 caused by the Velcro assembly. Of course, in some embodiments, the Velcro loop surface 82 or the fleece surface can also be directly used as the upper surface material of the lower pad layer 1, saving installation steps and materials.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
