[0002] This application requires:

[0003] 1. On June 28, 2023, the present invention was filed with the State Intellectual Property Office of China with application number: 202321665605.3, and the name of the invention is: "A modular elastic mattress"; the present invention is based on the Chinese patent application and claims its priority. The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0004] The present application relates to the technical field of furniture cushions, and in particular to an elastic mattress with a modular structure. Background Art

[0005] In order to ensure the comfort and softness of mattresses, mattresses generally have a built-in support structure. This support structure is generally a spring structure. The spring structure in the mattress is generally integrated, packed with non-woven fabric or cotton cloth into a bag, and then sealed by gluing or ultrasonic welding to form a bed net with an array arrangement, which plays an elastic support role. This type of spring structure is called an independent tube spring.

[0006] The springs of this type of independent tube spring are not connected by steel wire rings, but are independent of each other. Even if the person next to the pillow turns over and moves sideways, it will not affect the other person's sleep. At the same time, it can evenly bear the pressure of every point on the body.

[0007] During the manufacturing process, the independent tube springs need to be individually wrapped with non-woven fabrics, ultrasonically welded, and then arranged and glued to form a bed net. This has the disadvantages of complicated manufacturing process and high production cost. In addition, because each spring body operates individually, expands and contracts independently, its elasticity and durability are weak, and regular maintenance by manpower is required, resulting in high maintenance costs.

[0008] Summary of the Invention

[0009] In order to solve the above problems, simplify the production process, reduce costs, and facilitate regular maintenance, the present application provides a modular elastic mattress, which adopts the following technical solutions:

[0010] A modular elastic mattress comprises a face mask, a spring module, a spring fixing bracket, and a base, which are arranged in order from top to bottom; the face mask is sleeved on the base to form a receiving cavity; the spring module is assembled on the spring fixing bracket to form a supporting structure, and is placed in the receiving cavity;

[0011] The spring module includes a plurality of cloth bag springs, and the plurality of cloth bag springs are arranged in an array on the spring fixing support.

[0012] In a preferred embodiment, a plurality of holes are correspondingly provided on the spring fixing bracket for accommodating the bag springs.

[0013] In a preferred embodiment, the spring fixing bracket is formed by splicing together a plurality of sub-fixing brackets; each of the sub-fixing brackets has a plurality of holes distributed at equal intervals.

[0014] In a preferred embodiment, the sub-fixing bracket is a rectangular module.

[0015] In a preferred embodiment, the depth of the hole is set to 1 / 3-1 / 4 of the height of the bag spring.

[0016] In a preferred embodiment, a limiting structure is provided on a side of the spring fixing bracket facing the base, and the limiting device is used to limit the relative position of the spring fixing bracket and the base along the horizontal direction.

[0017] In a preferred embodiment, the limiting structure includes a first wave pattern provided on the spring fixing support and a second wave pattern provided on the base, and the first wave pattern and the second wave pattern are staggered and engaged with each other to form a limiting fit.

[0018] In a preferred embodiment, the mask is detachably connected to the base via a fixing ring.

[0019] In a preferred embodiment, a ring groove is provided on the periphery of the base for clamping the fixing ring.

[0020] In a preferred embodiment, a sponge comfort layer is provided between the spring module and the mask.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. Holes are provided on the spring fixing support for placing the bag springs. After the bag springs are built into bags, they can be directly put into the mattress for installation and use. No additional ultrasonic welding or sorting gluing is required, which simplifies the manufacturing process and reduces production costs.

[0023] 2. The spring fixing bracket is divided into sub-fixing brackets, which can break down a large-sized mattress into smaller parts, making it easier to transport and assemble. The sub-modular design also allows for targeted replacement and maintenance in the event of partial collapse.

[0025] 4. The spring fixing bracket is fitted with the base in a wavy pattern to ensure that the spring fixing bracket does not slide relative to the base, further stabilizing the shape and structure of the mattress and maintaining the overall beauty.

[0026] 5. The mask and the base are detachable with a fixing ring, which is convenient for repairing local collapse. The modular detachable structure of the mattress can realize the sunlight sterilization function of the mattress, which is convenient for cleaning the mattress. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below with reference to Figures 1-7.

[0036] An embodiment of the present application discloses an elastic mattress with a modular structure, comprising a mask 1, a sponge comfort layer 6, a spring module 2 and a sponge base 4 arranged in sequence from top to bottom. The mask 1 is made of a mesh fabric, and the mesh structure gives the mask 1 a certain elasticity, which is suitable for the elastic structure of the mattress.

[0037] The mask 1 is placed on the sponge base 4, and together with the sponge base 4, forms a structure with an accommodating cavity. The accommodating cavity is used to accommodate the spring module 2 and the sponge comfort layer 6. The sponge comfort layer 6 is placed flat on the spring module 2 to support the mask 1, so that the mattress as a whole has a fluffy feeling, and can buffer the elasticity of the spring module 2, while increasing the softness of the mattress.

[0038] In this embodiment, the elastic mattress is provided with a sponge spring fixing bracket 3 in the accommodating cavity, and the spring module 2 is mounted on the sponge spring fixing bracket 3 to form a supporting structure.

[0039] Furthermore, the spring module 2 includes a plurality of pocket springs 21. These pocket springs 21 are composed of springs 212 embedded within a pocket 211. The springs 212 are placed within the pocket 211 and sewn together using ultrasonic welding to form the pocket spring 21. The pocket springs 21 have a curved structure with a smaller central diameter than their two ends. The ends of the pocket springs 21 serve as support points. This curved structure improves the durability of the springs 212 and the stability of their elastic extrusion.

[0040] In terms of the structure of the spring 212, the turns or spirals of its coil body are designed with different diameters, and the diameter is set to continuously increase from the middle section of the spring to the two ends. The change in the diameter adjusts the overall elastic force and support stiffness of the spring 212. For example, the coil bodies at the two ends of the spring 212 have more obvious stiffness than the coil bodies in the middle section, which is defined as the support surface. The coil body in the middle section of the spring 212 has a more obvious spring rate than the coil bodies at its two ends, and it serves as the main structure for supporting the elastic deformation of the mattress.

[0041] In this embodiment, the upper surface of the spring retaining bracket 3 is provided with a plurality of corresponding holes 31 for receiving the pocket springs 21. The pocket springs 21 are sequentially placed into the holes 31 on the upper surface of the sponge spring retaining bracket 3. The sponge spring retaining bracket 3 is used to secure the pocket springs 21, so that the pocket springs 21 form an array-distributed bed net support structure. The pocket springs 21 are not secured by gluing, ensuring the independence of each pocket spring 21. This reduces the interference between adjacent springs caused by the gluing structure when compressing a single spring, further reducing collapse.

[0042] Furthermore, in order to achieve a better elastic effect, the depth of the hole 31 is set to 1 / 3-1 / 4 of the height of the bag spring 21, providing sufficient space for the compression of the bag spring 21, while ensuring that the bag spring 21 can be stable in the hole 31, avoiding bouncing out of the hole 31 and causing local collapse and damage.

[0043] In this embodiment, due to the height difference between the pocket spring 21 and the sponge spring mounting bracket 3, the pocket spring 21 is partially positioned outside the sponge mounting bracket 3. Therefore, the sponge comfort layer 6 is laid above the end of the pocket spring 21. The sponge comfort layer 6 serves as a transition between the human body and the pocket spring. The sponge material ensures that the sponge comfort layer 6 has a certain degree of flexibility and elastic deformation when its surface contacts the human body. Furthermore, as a load-bearing component, the sponge comfort layer 6 has an appropriate thickness to withstand stress.

[0044] In this embodiment, a limiting structure is provided on the side where the sponge spring fixing bracket 3 and the sponge base 4 are placed facing each other, for limiting the relative position of the sponge spring fixing bracket 3 and the sponge base 4 along the horizontal direction, thereby preventing the sponge spring fixing bracket 3 from sliding out of the sponge base 4, causing the side of the mattress to bulge, unstable support, and the mattress to tip over.

[0045] Furthermore, the limiting structure includes a first wave pattern 32 arranged on the sponge spring fixing support 3 and a second wave pattern 41 arranged on the sponge base 4. The first wave pattern 32 and the second wave pattern 41 are staggered and engaged with each other to form a limit. The upper and lower wave pattern structures are fitted together to ensure that the sponge spring fixing support 3 and the sponge base 4 fit perfectly without leaving any gaps, forming a stable mattress. The wave patterns can play a good role in mutual abutment, ensuring that the position of the sponge spring fixing support 3 will not slip relatively.

[0046] In this embodiment, the mask 1 is detachably connected to the sponge base 4 by a fixing ring 5. An annular groove 42 is provided on the peripheral side of the sponge base 4. The depth of the annular groove 42 is half the thickness of the fixing ring 5. The fixing ring 5 is provided with a certain elasticity. After the mask 1 covers the spring module 2 and the sponge comfort layer 6, it is fixed to the sponge base 4 by the fixing ring 5 to complete the assembly of the mattress.

[0047] Furthermore, in order to better form a fixed structure, the fixing ring 5 is selected to be connected and fixed with the mask opening of the mask 1. After the mask 1 is completely covered, it is fixed by snapping the fixing ring 5 with the annular groove 42. The mesh structure of the mask 1 and the elastic structure of the fixing ring 5 can act to press the fixing ring 5 inward into the annular groove 42. The structure of the annular groove 42 limits the up and down movement of the fixing ring 5, thereby realizing a fixed connection between the mask 1 and the sponge base 4.

[0048] When an external force acts on the fixing ring 5 to separate outward from the annular groove 42 , the face cover 1 can be removed, and the mattress disassembly work is completed.

[0049] In the first embodiment, the fixing ring 5 is a separate part. After the mask 1 covers the spring module 2 and the sponge comfort layer 6, the mask opening of the mask 1 is placed at the corresponding position of the annular groove 42, and the fixing ring 5 is clamped in the annular groove 42 and at the same time, the mask opening of the mask 1 is locked in the annular groove 42 to achieve a fixed connection.

[0050] In the second embodiment, the sponge spring retainer 3 is divided into several sub-retainers 33. Each sub-retainer 33 has 16 to 28 holes 31 spaced evenly apart for receiving the pocket springs 21. The sub-retainers 33 can be connected to accommodate different mattress sizes. The modular design of the mattress also allows for disassembly, cleaning, and sun sterilization, ensuring hygienic and safe use.

[0051] Furthermore, the sub-fixing bracket 33 is a rectangular module, and the rectangular structure can be quickly spliced ​​and meet the splicing requirements of mattresses of different sizes.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
