[0001] This invention relates to the field of mattress technology, and more specifically to a modular mattress structure. Background Technology

[0002] In daily life, mattresses are a core product for ensuring the quality of human sleep, and their comfort, practicality, and convenience directly affect the user's life experience.

[0003] Double mattresses are widely used in family bedrooms and hotel rooms because they can meet the needs of two people sleeping together. Most existing double mattresses are one-piece structures, and to accommodate the sleeping needs of two people, they are usually large in size. The mattresses are filled with various materials such as foam, springs, and latex, resulting in a relatively heavy overall weight. Furthermore, different individuals have different physical conditions and sleeping habits, and therefore different needs regarding mattress firmness. Some users prefer soft mattresses for better support, while others prefer firmer mattresses to ensure the normal physiological curvature of the spine.

[0004] Because double mattresses are large, they cannot be folded or disassembled for storage purposes, requiring a lot of storage space when not in use. However, traditional double mattresses use a single firmness structure, which cannot achieve left and right zone differences on the same plane, making it difficult to meet the different needs of two people for mattress firmness at the same time.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention discloses a modular mattress structure.

[0035] Example 1: Refer to Figure 1-9 This invention provides a first embodiment of a modular mattress structure, comprising a main mattress 1 and a secondary mattress 2. A seam-sealing pad 3 is provided at the hinge between the main mattress 1 and the secondary mattress 2. The main mattress 1 is hinged to the secondary mattress 2 via a connecting mechanism 4, and adjacent main mattresses 1 and secondary mattresses 2 are connected by splicing blocks 5. The two ends of the splicing blocks 5 are respectively installed in corresponding grooves of the main mattress 1 and the secondary mattress 2 using screws. The main mattress 1 and the secondary mattress 2 have a hard surface 6 and a flexible surface 7 on their respective sides, and the seam-sealing pad 3 is flush with the surfaces of the main mattress 1 and the secondary mattress 2. By setting a detachable structure for the main mattress 1 and the secondary mattress 2, the volume and weight of individual components can be reduced through disassembly, facilitating single-person operation and handling, and allowing for easy storage when not in use. The mattress can be folded and stored away. The seam-sealing pad 3 can fill the gap at the hinge between the main mattress 1 and the secondary mattress 2, preventing the body from sinking into the gap during sleep and affecting comfort. It also ensures the flatness of the sleeping surface of the main mattress after combination. The connecting mechanism 4 provides structural support for subsequent folding and unfolding, and enables relative rotation between the main mattress 1 and the secondary mattress 2. The splicing block 5 adopts a detachable connection method with screws, which not only ensures the connection stability of adjacent mattresses after splicing and prevents relative displacement during use, but also facilitates flexible disassembly and combination according to usage needs. Both the main mattress 1 and the secondary mattress 2 have a firm surface 6 and a soft surface 7 on both sides, allowing users to choose the surface according to their own firmness needs. At the same time, the disassembly and combination structure design can meet the different firmness needs of the left and right sections when two people are sleeping.

[0036] The secondary mattress 2, near the main mattress 1, is equipped with a hinged cover 21 corresponding to the connecting mechanism 4. The end of the hinged cover 21 extending into the secondary mattress 2 is equipped with a pivot that is hinged to the secondary mattress 2. A handle is also sewn onto the hinged cover 21. The hinged covers 21 are symmetrically distributed at both ends of the seam-sealing pad 3. The hinged covers 21 are mainly used to cover the connecting mechanism 4. They can be closed magnetically or with Velcro to prevent the connecting mechanism 4 from being exposed to the outside and accumulating dust and moisture, thus extending its service life. On the other hand, they can improve the overall aesthetics of the mattress and prevent users from being scratched by the metal or plastic parts of the connecting mechanism 4 during sleep or use. The design of the pivot and the handle allows the hinged cover 21 to be opened and closed flexibly, making it easy to observe the operating status of the connecting mechanism 4 in real time. It also forms a synergistic protection with the seam-sealing pad 3, fully covering the key structure at the hinge.

[0037] The two ends of the grout patch 3 are respectively provided with Velcro that can be glued to the hinge cover 21. The Velcro on the grout patch 3 and the handle on the hinge cover 21 are arranged to avoid each other. The Velcro is designed to allow the grout patch 3 to be detachably and fixedly connected to the hinge cover 21, which not only ensures the positional stability of the grout patch 3 during use, but also makes it easy for users to quickly remove the grout patch 3 according to their needs.

[0038] The linking mechanism 4 includes a linking seat 41 fixedly installed on the main mattress 1 and the secondary mattress 2 respectively. The linking seat 41 is rotatably connected to a driven gear 411 and a driving gear 412 corresponding to the main mattress 1 and the secondary mattress 2 respectively. The driven gear 411 and the driving gear 412 are connected by a transmission frame 42, and the driven gear 411 and the driving gear 412 mesh with each other. The linking seat 41 serves as the basic support component of the linking mechanism 4. The corresponding gear assemblies can be installed on the main mattress 1 and the secondary mattress 2 respectively by screws. The meshing of the driven gear 411 and the driving gear 412, in conjunction with the connection function of the transmission frame 42, enables the main mattress 1 and the secondary mattress 2 to rotate synchronously and smoothly around the hinge. The meshing action increases the friction at the hinge and improves the hinge stability.

[0039] The gear shaft on the driven gear 411 is fixedly connected to the end of the transmission frame 42 away from the driving gear 412. The transmission frame 42 is also fixedly installed with a threaded mating screw block 43. The mating screw block 43 is threadedly connected to a locking stud 431 for locking and limiting. The gear shaft of the driven gear 411 can transmit the rotational power of the deflection and folding driving gear 412 of the secondary mattress 2 to the transmission frame 42 through the transmission frame 42, thereby driving the main mattress 1 and the secondary mattress 2 to rotate relative to each other, ensuring the continuity and stability of the transmission structure. The threaded mating structure of the mating screw block 43 and the locking stud 431 provides a locking and limiting function for the folding or unfolding state of the mattress. When the mattress is adjusted to the desired state, the position of the transmission frame 42 can be fixed by tightening the locking stud 431, thereby locking the relative angle of the main mattress 1 and the secondary mattress 2 and preventing the mattress from rotating on its own during use or storage.

[0040] One side of the main mattress 1 has adjustable screw holes 101 that are compatible with locking studs 431. When the locking studs 431 are tightened, one end of the locking studs 431 passes through the corresponding adjustable screw holes 101 and is connected to the inner wall of the mating screw block 43 by thread engagement. The adjustable screw holes 101 provide multiple locking positions for the locking studs 431, allowing the main mattress 1 and the secondary mattress 2 to be adjusted to different relative angles and locked according to actual needs, thus improving the flexibility of the mattress. For example, it can be adjusted to a fully unfolded flat state for sleeping, or to a tilted state at a certain angle for users to lean against for reading, watching movies, etc., and its footprint can be reduced by folding, making it easy to store.

[0041] Both the main mattress 1 and the secondary mattress 2 have a base plate layer 8 and an anti-abrasion fiber layer 9 on the side facing the firm surface 6. The base plate layer 8 also has a cushioning felt layer 11 on the side away from the anti-abrasion fiber layer 9. The base plate layer 8 provides core support for the firm surface 6, ensuring the firmness required when the firm surface 6 is used as a sleeping surface, and is suitable for users who prefer a firmer mattress. The anti-abrasion fiber layer 9 is located on the outermost side, which can improve the abrasion resistance of the firm surface 6 as a sleeping surface, reduce wear and tear during daily use, extend the life of the mattress, and also meet the needs of using the firm surface 6 as a sleeping surface. The cushioning felt layer 11 is located between the base plate layer 8 and the internal structure of the mattress, which can alleviate the stiffness of the firm surface 6 as a sleeping surface, improve the comfort while ensuring support, and avoid discomfort caused by the base plate layer 8 being too firm.

[0042] Both the main mattress 1 and the secondary mattress 2 have a spring array layer 10, a supporting fiberboard layer 12, a memory foam filling layer 13, and a knitted fiber layer 14 arranged sequentially on the side facing the flexible surface 7. A cushioning felt layer 11 is also provided between the spring array layer 10 and the supporting fiberboard layer 12. The spring array layer 10 uses silent pocket springs, which can provide elastic support for the flexible surface 7 and adapt to the curves of the human body through the elastic deformation of the springs, distributing body pressure. Compared with traditional Simmons mattresses, it is lighter. The supporting fiberboard layer 12 can limit and support the spring array layer 10, preventing excessive deformation of the springs. The flexible surface 7 can be shifted to ensure its support stability as a sleeping surface. The memory foam filling layer 13 has slow rebound properties, which can further conform to the human body contour, improve the feeling of being wrapped and comfortable, and relieve physical fatigue during sleep. The knitted fiber layer 14 is located on the outermost side and has the characteristics of being soft, breathable and skin-friendly, which improves the tactile experience when the user touches it. The buffer felt layer 11 between the spring array layer 10 and the supporting fiberboard layer 12 can reduce the transmission of spring vibration, reduce the noise caused by the body turning over during sleep, and further improve the buffering effect of the flexible surface 7 as a sleeping surface.

[0043] The main mattress 1 and the main mattress 2, or the main mattress 1 and the secondary mattress 2, or the secondary mattress 2 and the secondary mattress 2 are combined to form the main body of the mattress. The main mattress 1 and the secondary mattress 2 are equipped with shaping frames along their outer contours. The flexible combination design of multiple sets of main mattress 1 and secondary mattress 2 can adapt to different sleep needs. For example, a single set of main mattress 1 and secondary mattress 2 with the same orientation of the hard surface 6 or the soft surface 7 can form a standard double mattress with the same sleeping surface. Multiple sets can be combined to form a larger size mattress for multiple people to use, which improves the versatility of the product and the range of applicable scenarios. The shaping frame is a wooden frame or a composite plastic frame set along the outer contour of the mattress, which can effectively maintain the shape of the mattress and avoid edge collapse or deformation caused by uneven force during use.

[0044] When using this mattress, first align and hinge the main mattress 1 and the secondary mattress 2 through the connecting mechanism 4. Then, lift and open the hinge cover 21 using the handle to observe the precise meshing of the driven gear 411 and the driving gear 412 on the connecting seat 41, completing the basic hinge positioning. Confirm the position of the different sleeping surfaces as a single mattress or a double mattress. After placing the main mattress 1 and the secondary mattress 2 on the corresponding sleeping surfaces and ensuring they are level, insert the two ends of the splicing block 5 into the corresponding grooves of the main mattress 1 and the secondary mattress 2 respectively, and tighten them with screws to further enhance the connection stability of the adjacent mattresses and prevent relative displacement during use. Finally, attach the seam filling pad 3 to the hinge joint of the main mattress 1 and the secondary mattress 2. Secure it with the Velcro on both ends of the seam filling pad 3 to the closed hinge cover 21 on the secondary mattress 2, ensuring that the seam filling pad 3 is flush with the surface of each mattress and fills the hinge gap. At the same time, the hinge cover 21 closes through the pivot, forming a shield and protection for the connecting mechanism 4, completing the overall assembly.

[0045] When the sleeping surfaces for two people are different, users can choose the individual sleeping surface of the mattress according to their own needs. By combining and splicing, the sleeping areas for two people can be divided into left and right sections with different firmness. For example, one side can use a firm surface 6 and the other side can use a soft surface 7, or both can be firm surface 6 or soft surface 7. The adjacent main mattress 1 and secondary mattress 2 can be freely spliced ​​and combined with screws and splicing blocks 5. The base plate layer 8 on the firm surface 6 side of the main mattress 1 and secondary mattress 2 provides rigid support, the cushioning felt layer 11 alleviates the stiffness, the anti-abrasion fiber layer 9 improves durability, the knitted fiber layer 14 provides a better skin feel for the soft surface 7 as the sleeping surface, and the supporting fiberboard layer 12 provides a certain degree of support to prevent excessive softness and collapse. The silent pocket spring array layer 10 on the soft surface 7 side provides elastic support and pressure distribution. Combined with the slow rebound characteristics of the memory foam filling layer 13, it improves the feeling of being wrapped. The cushioning felt layer 11 between the two reduces the noise of spring vibration. The shaping skeleton of the outer contour of the main body of the mattress after combination effectively maintains the shape of the mattress and prevents the edges from collapsing and deforming.

[0046] When storage or folding is required, the hinged cover 21 is opened by lifting, and the secondary mattress 2 is manually flipped. This causes the connecting seat 41 on the flipped secondary mattress 2 to rotate, connecting the active gear 412 to drive the driven gear 411 to rotate synchronously. Power is transmitted through the transmission frame 42 connected to the gear shaft of the driven gear 411, allowing the secondary mattress 2 to smoothly deflect around the hinge point with the main mattress 1 and adjust to the desired angle, such as the fully unfolded sleeping position or the tilted reclining position. Then, the locking stud 431 is passed through the corresponding adjustment screw hole 101 on the main mattress 1 and threaded onto the connecting screw block 43 to lock the position of the transmission frame 42, thereby fixing the relative angle of the main mattress 1 and the secondary mattress 2. This meets the needs of multiple scenarios such as sleeping, reading, and watching movies. At the same time, folding reduces the floor space and makes it easy to store.
