Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to an elastic supporting structure. Background Art

[0002] In the field of mattress manufacturing, the edge support system is a key part to ensure the overall stability and durability of the mattress. Traditional mattress edges usually do not have special structures, which leads to the corners of the mattress easily collapsing or deforming after long-term use, affecting sleep quality and the service life of the mattress. As people's requirements for sleep quality improve, the demand for mattress comfort and durability is also increasing, which puts higher requirements on the elastic support structure of the mattress edge. The early elastic support structure is M-clamp type, with a spring coil in the center to enhance support and prevent the edge of the mattress from collapsing and deforming. However, there is only one spring coil, which may cause it to lose its original support capacity after long-term use. Its cushioning and elasticity are not in good condition. The elastic support structure is not strong enough, and long-term use can easily cause the edge of the mattress to deform or even be damaged, affecting the user experience. Utility Model Content

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0031] Example 1

[0032] Reference Figure 1-Figure 3 This embodiment relates to an elastic support structure, which is formed by winding a rigid part, and the rigid part includes: a first cross bar portion 1, a first coil portion 2, a first oblique bar portion 3, a second coil portion 4, a second oblique bar portion 5, a third coil portion 6 and a second cross bar portion 7.

[0033] Among them, one end of the first crossbar portion 1 is connected to the first coil portion 2, and the other end is a free end. The other end of the second crossbar portion 7 is connected to the third coil portion 6, and the other end is a free end. The first crossbar portion 1 and the second crossbar portion 7 are arranged in parallel. The two parallel crossbar portions constitute the basic framework of the elastic support structure, providing the main supporting force to maintain the horizontal stability and load-bearing capacity of the structure. One end of the first coil portion 2 is connected to one end of the first crossbar portion 1, with its middle portion wound into a loop and the other end extending downward. One end of the first oblique rod portion 3 is connected to the lower end of the first coil portion 2, and the other end extends downward. One end of the second coil portion 4 is connected to the lower end of the first oblique rod portion 3, with its middle portion wound into a loop and the other end extending downward. One end of the second oblique rod portion 5 is connected to the lower end of the second coil portion 4, with its other end extending downward and bent with the first oblique rod portion 3. One end of the third coil portion 6 is connected to the lower end of the second oblique rod portion 5, with its middle portion wound into a loop and the other end extending horizontally and being axially symmetrical with the first coil portion 2. Two diagonal rods are connected between the crossbars to form a stable triangular structure, providing additional rigidity and bending resistance. At the same time, they are interconnected with the crossbars to form the overall framework of the elastic support structure. The three coil sections can effectively absorb and disperse external forces, reducing structural damage caused by external impact or vibration, while also having good shock absorption and buffering properties. The first diagonal rod section 3 and the second diagonal rod section 5 are bent, and the first coil section 2 and the third coil section 6 are axially symmetrical. Therefore, the elastic support structure is horizontally M-shaped, forming multiple support points to provide uniform support force, ensuring more uniform support at different positions on the mattress edge, preventing the mattress edge from collapsing or deforming, and having the advantages of good cushioning and high elasticity.

[0034] In this embodiment, referring to Figure 1-Figure 3 The angle between the first diagonal rod portion 3 and the second diagonal rod portion 5 is 15°. This angle shortens the distance between the first diagonal rod portion 3 and the second diagonal rod portion 5, thereby making the entire elastic support structure more compact and helping to form a more stable triangular structure, further enhancing the stability and rigidity of the structure and reducing deformation under stress. In other embodiments, to accommodate different mattress types and sizes, the angle between the first diagonal rod portion 3 and the second diagonal rod portion 5 can also be 12°, 13°, 14°, 16°, or 17°. As long as the angle between the crossbar portion and the diagonal rod portion is within the range of 12° to 17°, no specific limitation is imposed herein.

[0035] In this embodiment, referring to Figure 1-Figure 3 The first coil section 2, the second coil section 4, and the third coil section 6 all have 1.5 turns. This 1.5-turn coil provides moderate shock absorption and cushioning, neither too soft nor too rigid. It ensures adequate support while providing moderate elasticity, allowing the mattress edge to quickly return to its original shape when compressed. In other embodiments, the first coil section 2, the second coil section 4, and the third coil section 6 can have multiple turns, depending on user needs or to accommodate different mattress types. This is not specifically limited here.

[0036] In this embodiment, referring to Figures 1-4 The second coil portion 4 is arranged in the middle between the first crossbar portion 1 and the second crossbar portion 7. This effectively increases the support force of the central area of ​​the entire structure, avoids the sinking phenomenon caused by insufficient load-bearing in the central area, and further improves the overall stability.

[0037] In this embodiment, referring to Figures 1-4 , the angles between the first crossbar portion 1 and the first diagonal portion 3, and between the second crossbar portion 7 and the second diagonal portion 5 are both 53°. The setting of the 53-degree angle can effectively balance the rigidity and flexibility of the structure. The connection between the diagonal portion and the crossbar portion is neither too rigid nor too loose, and can provide sufficient elasticity while ensuring the stability of the structure. In other embodiments, in order to adapt to different mattress types and sizes, the angles between the first crossbar portion 1 and the first diagonal portion 3, and between the second crossbar portion 7 and the second diagonal portion 5 can also be 50°, 51°, 52°, 54°, or 55°. As long as the angle between the crossbar portion and the diagonal portion is within the range of 50° to 55°, no specific limitation is made here.

[0038] In this embodiment, referring to Figures 1-4, the length of the diagonal rod portion accounts for 70% of the length of the cross bar portion, the length of the first cross bar portion 1 and the second cross bar portion 7 is 20 cm; the length of the first diagonal rod portion 3 and the second diagonal rod portion 5 is 14 cm. The cross bar portion and the diagonal rod portion can reasonably distribute the supporting force to avoid insufficient or excessive local support. In other embodiments, in order to adapt to the types and sizes of different mattresses, the lengths of the first cross bar portion 1 and the second cross bar portion 7 can also be 15 cm, 18 cm, 22 cm, 25 cm; the lengths of the first diagonal rod portion 3 and the second diagonal rod portion 5 can also be set to 10 cm, 12 cm, 16 cm. As long as the lengths of the first cross bar portion 1 and the second cross bar portion 7 are in the range of 15-25 cm, and as long as the lengths of the first diagonal rod portion 3 and the second diagonal rod portion 5 are in the range of 10-16 cm, no specific restrictions are made here.

[0039] Specifically in this embodiment, refer to Figures 1-4 The spacing between the first crossbar 1 and the second crossbar 7 is 18 cm. In other embodiments, to accommodate different mattress types and sizes, the spacing between the first crossbar 1 and the second crossbar 7 can also be 16 cm, 17 cm, 19 cm, or 20 cm. As long as the spacing between the first crossbar 1 and the second crossbar 7 is within the range of 16-20 cm, no specific limitation is imposed.

[0040] In this embodiment, referring to Figures 1-4 , the diameter of the second coil part 4 accounts for 73% of the diameter of the first coil part 2 and the third coil part 6. The diameters of the first coil part 2 and the third coil part 6 are both 26 mm; the diameter of the second coil part 4 is 19 mm. Spring coils of different diameters can optimize the distribution of supporting force and enhance structural stability. In other embodiments, in order to adapt to different mattress types and sizes, the diameters of the first coil part 2 and the third coil part 6 can also be 22 mm, 24 mm, and 28 mm; the diameter of the second coil part 4 can also be 17 mm, 18 mm, and 20 mm. As long as the diameters of the first coil part 2 and the third coil part 6 are in the range of 22-28 mm, and as long as the diameter of the second coil part 4 is in the range of 17-20 mm, no specific limitations are made here.

[0041] In this embodiment, the rigid member is made of high-carbon manganese steel. High-carbon manganese steel has high strength and toughness. The elastic support structure, constructed by winding a single rigid member, eliminates potential weaknesses associated with traditional welding or assembly, making the entire structure more robust and capable of withstanding greater loads. Furthermore, the high elasticity of high-carbon manganese steel enables the spring coil to provide excellent elastic properties. In other embodiments, the rigid member may also be made of other materials.

[0042] Specifically in this embodiment, refer to Figure 3Applying the elastic support structure of this embodiment to a mattress not only ensures more uniform support at different locations along the mattress edge, but also effectively prevents the mattress edge from collapsing or deforming, while providing excellent cushioning and elasticity. In other embodiments, the elastic support structure of this embodiment can also be applied to other products such as sofas or other fields.

[0043] Example 2

[0044] Reference Figure 4 This embodiment is substantially the same as the first embodiment, except that: an elastic support structure comprises: the first crossbar portion 1, the first coil portion 2, the first oblique rod portion 3, the second coil portion 4, and the second crossbar portion 7 as described above. The rigid member further comprises: a second oblique rod portion 5, one end of which is connected to the lower end of the second coil portion 4, the other end of which extends downward and is arranged in a straight line with the first oblique rod portion 3; and a third coil portion 6, one end of which is connected to the lower end of the second oblique rod portion 5, the middle portion of which is wound in a loop, the other end of which extends horizontally and is centrally symmetrical with the first coil portion 2. It can be seen that the first oblique rod portion 3 and the second oblique rod portion 5 are arranged in a straight line, and the first coil portion 2 and the third coil portion 6 are centrally symmetrical. Therefore, the elastic support structure is Z-shaped. The Z-shaped structure has a relatively simple linear structure, is easier to manufacture and assemble, makes the middle portion more flexible and comfortable when subjected to force, provides efficient support, enhances the vertical stability of the structure, prevents the edge of the mattress from collapsing or deforming, and has the advantages of good cushioning and high elasticity.

[0045] Specifically in this embodiment, since the first oblique rod portion 3 and the second oblique rod portion 5 are arranged in a straight line, the angle between the first oblique rod portion 3 and the second oblique rod portion 5 is 180°, which further enhances the stability of the structure in the vertical direction.

[0046] In this embodiment, the first coil portion 2 and the third coil portion 6 each have 1.5 turns, and the second coil portion 4 has 1 turn. The first coil portion 2 and the third coil portion 6 have a relatively large number of turns (1.5 turns), which can provide stronger support and ensure that the two ends of the mattress edge are more stable when subjected to force. The second coil portion 4 has a relatively small number of turns (1 turn), which can provide moderate support and make the middle portion softer and more comfortable when subjected to force. In other embodiments, the first coil portion 2, the second coil portion 4, and the third coil portion 6 can also have multiple turns according to different user needs or to adapt to different types of mattresses, which is not specifically limited here.

[0047] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
