Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to an elastic support component and furniture. Background Technology

[0002] Traditional sofas typically use serpentine springs (commonly known as "snake springs") as the main load-bearing component in their support structure. These springs are made of metal and are arranged in a continuous wave or serpentine pattern, running laterally across the entire sofa cushion area and connecting to the sofa frame at both ends. This structure offers advantages such as low cost and easy installation, and is widely used in various sofa products from different manufacturers.

[0003] However, this long-span design with fixed ends results in a lack of effective support in the middle area of ​​the serpentine spring. Under prolonged pressure, the center of the seat cushion bears a concentrated load, causing the serpentine spring's elasticity to gradually diminish and undergo plastic deformation, ultimately leading to permanent sagging in the middle area. This problem not only affects the sofa's aesthetics but also reduces seating comfort and can even cause lower back fatigue due to uneven support.

[0004] Therefore, the existing passenger support structure needs to be improved to solve the problem that its central area is prone to sinking due to insufficient support.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide an elastic support member and furniture that can effectively solve the problem that the central area of ​​existing seating support structures is prone to sinking due to insufficient support.

[0007] To achieve the above objectives, this utility model provides an elastic support member, comprising:

[0008] A supporting frame, which encloses an elastic support area;

[0009] A central pad, wherein the central pad is located at the center of the elastic support area;

[0010] A plurality of main tensile elastic elements are arranged around the central gasket and connected to the supporting frame.

[0011] Optionally, each of the main tensile elastic elements connects the central gasket to each of the top corners of the support frame.

[0012] Optionally, it may also include an elastic mesh located above the central gasket and each of the main tensile elastic elements.

[0013] Optionally, the elastic mesh includes a plurality of longitudinal tensile elastic members arranged parallel to the length direction of the supporting frame, and a plurality of transverse tensile elastic members arranged parallel to the width direction of the supporting frame.

[0014] The ends of each of the secondary tensile elastic members are fixed to the support frame and span the elastic support area.

[0015] Optionally, the tensile properties of the main tensile elastic member are superior to those of the longitudinal secondary tensile elastic member and the transverse secondary tensile elastic member.

[0016] Optionally, the main tensile elastic element is a serpentine spring or a tension spring, and the longitudinal secondary tensile elastic element and the transverse secondary tensile elastic element are both elastic bands.

[0017] Optionally, the center pad is a metal disc or an engineering plastic plate.

[0018] On the other hand, a type of furniture is provided, including:

[0019] Furniture base;

[0020] The elastic support member described above is located above the furniture base and is used to provide upward elastic support to the human body.

[0021] A lifting and adjusting mechanism is installed and fixed on the furniture base to support the central pad of the elastic support member upwards.

[0022] Optionally, the lifting and adjusting mechanism is a pneumatic cylinder, hydraulic cylinder, electric cylinder, or motor lead screw module.

[0023] Optionally, a soft padding layer is also provided above the elastic support.

[0024] The beneficial effects of this utility model are as follows: It provides an elastic support component and furniture, which creatively adopts a combined structure of "central pad + radial main tensile elastic components," fundamentally reconstructing the transmission path of the supporting force. The central pad, as the rigid support core, is located in the very center of the elastic support area, directly bearing the concentrated load when a person sits on it, which is in stark contrast to the unsupported central area in traditional serpentine spring structures. Multiple main tensile elastic components extend radially outward from the central pad, evenly connecting to various positions on the support frame, forming a mechanical distribution system similar to bicycle wheel spokes. This layout allows the pressure borne by the central pad to be distributed in multiple directions, and each main tensile elastic component only needs to bear a portion of the load, significantly reducing the stress intensity of a single main tensile elastic component.

[0025] When the central gasket is compressed, the radially arranged main tensile elastic elements generate centripetal tension, forming a dynamic balance mechanism that automatically compensates for any potential sinking displacement. Compared to the traditional long-span design of serpentine springs with fixed ends and a suspended center, this invention shortens the effective support span to less than half that of traditional structures through the central gasket, allowing the main tensile elastic elements to primarily bear tensile force rather than bending stress, thus avoiding plastic deformation of the metal material due to repeated bending. This innovative structural system of "central rigid support node + multi-directional elastic dispersion" not only solves the problem of weak support in the central area of ​​traditional structures but also achieves a more uniform load distribution and a more durable elastic retention capability through optimization of the mechanical path, thereby solving the problem of the central area of ​​existing ride support structures easily sinking due to insufficient support.

[0043] This utility model provides an elastic support component and furniture, which effectively solves the problem of insufficient support in the central area of ​​traditional sofas and chairs, causing them to sink, through its unique structural design.

[0044] Example 1

[0045] This embodiment will describe the specific structure of the elastic support provided by this utility model.

[0046] See Figure 1 In this embodiment, the elastic support 2 includes:

[0047] A supporting frame 201 is provided, which encloses an elastic support area.

[0048] A central pad 202 is located at the center of the elastic support area;

[0049] A plurality of main tensile elastic elements 203 are arranged around the central gasket 202 and connected to the support frame 201.

[0050] The aforementioned elastic support 2 creatively employs a combined structure of "central pad 202 + radial main tensile elastic elements 203," fundamentally reconstructing the transmission path of the supporting force. The central pad 202, as the rigid support core, is located in the very center of the elastic support area, directly bearing the concentrated load when a person sits on it. This contrasts sharply with the unsupported central area in traditional serpentine spring structures. Multiple main tensile elastic elements 203 extend radially outward from the central pad 202, evenly connecting to various positions on the support frame 201, forming a mechanical distribution system similar to bicycle wheel spokes. This layout allows the pressure borne by the central pad 202 to be distributed in multiple directions, with each main tensile elastic element 203 only needing to bear a portion of the load, significantly reducing the stress intensity of a single main tensile elastic element 203.

[0051] When the central gasket 202 is compressed, the radially arranged main tensile elastic elements 203 generate centripetal tension, forming a dynamic balance mechanism that automatically compensates for any possible downward displacement. Compared to the long-span design of traditional serpentine springs with fixed ends and a suspended center, this invention shortens the effective support span to less than half that of traditional structures through the central gasket 202, allowing the main tensile elastic elements 203 to primarily bear tensile force rather than bending stress, thereby avoiding plastic deformation of the metal material caused by repeated bending.

[0052] This innovative structural system of "central rigid support node + multi-directional elastic dispersion" not only solves the problem of weak support in the central area of ​​traditional structures, but also achieves a more uniform load distribution and a more durable elastic retention capability through the optimization of mechanical path, thereby solving the problem that the central area of ​​existing ride support structures is prone to sinking due to insufficient support.

[0053] In this embodiment, each of the main tensile elastic members 203 connects the central pad 202 to each of the apex corners of the supporting frame 201. This apex corner connection fully utilizes the rigid support points of the frame, making the elastic support area more evenly stressed, effectively preventing the central pad 202 from shifting or tilting, and further enhancing its anti-sag capability.

[0054] In this embodiment, an elastic net 204 is also provided above the central pad 202 and each of the main tensile elastic elements 203. The addition of the elastic net 204 covering the main tensile elastic elements 203 not only disperses local pressure and prevents the human body from directly compressing a single main tensile elastic element 203, thus improving riding comfort, but also forms a double-layer elastic support structure with the central pad 202, improving support performance.

[0055] Optionally, the elastic net 204 includes a plurality of longitudinal secondary tensile elastic members 2041 arranged parallel to the length direction of the support frame 201, and a plurality of transverse secondary tensile elastic members 2042 arranged parallel to the width direction of the support frame 201, wherein the ends of each secondary tensile elastic member are fixed on the support frame 201 and span the elastic support area.

[0056] The elastic mesh 204 is composed of longitudinal and transverse secondary tensile elastic elements 2042 interwoven to form a grid-like support surface. This orthogonal arrangement can evenly bear pressure from different directions, enhancing the integrity and stability of the support surface. The secondary tensile elastic elements are wound and fixed to the support frame 201 to ensure that the elastic mesh 204 is tightly connected to the main structure, preventing displacement or loosening, and making the support effect more durable and reliable.

[0057] In this embodiment, the tensile strength of the main tensile elastic element 203 is superior to that of the longitudinal secondary tensile elastic element 2041 and the transverse secondary tensile elastic element 2042. It can be understood that the primary tensile elastic element 203 has better tensile strength than the secondary tensile elastic elements, forming a well-defined mechanical system. The main tensile elastic element 203 undertakes the primary support function, ensuring the overall structural strength; the secondary tensile elastic elements provide auxiliary cushioning, optimizing local tactile feedback. This differentiated design ensures sufficient support while preventing the elastic mesh 204 from being too stiff and affecting comfort, achieving a balance between rigidity and flexibility.

[0058] For example, the main tensile elastic element 203 can be a serpentine spring or a tension spring, while the longitudinal secondary tensile elastic element 2041 and the transverse secondary tensile elastic element 2042 can be elastic bands. Serpentine springs / tension springs provide high-strength, fatigue-resistant support, while elastic bands are low-cost, moderately elastic, and suitable for large-area installation. This combination balances performance and economy, and the flexibility of the elastic bands reduces pressure on the skin, improving the user experience.

[0059] Optionally, the center gasket 202 can be a metal disc or an engineering plastic sheet. A metal disc has high strength and is suitable for heavy-duty applications; an engineering plastic sheet is lightweight and corrosion-resistant, making it suitable for humid environments. Both materials ensure long-term stable load-bearing capacity of the center gasket 202, preventing deformation or breakage, while allowing for flexible material selection to broaden its application range.

[0060] The elastic support 2 provided in this embodiment has the following advantages:

[0061] ① Structure of central pad 202 + radial main tensile elastic element 203: The concentrated load is directly borne by the rigid central pad 202, and the pressure is dispersed by the radial main tensile elastic element 203, which solves the problem of sinking caused by insufficient central support in traditional structures.

[0062] ② Short span tensile force-dominant design: The central gasket 202 shortens the support span, so that the main tensile elastic element 203 is mainly subjected to tensile force rather than bending stress, avoiding metal fatigue deformation and extending service life.

[0063] ③ Elastic mesh 204 covering design: An elastic mesh 204 is added above the main tensile elastic element 203 to disperse local pressure and form a double-layer support, improving comfort and overall support performance.

[0064] ④ Differentiated performance of primary and secondary elastic components: The primary tensile elastic component 203 (such as a serpentine spring) has better tensile performance than the secondary tensile elastic component (such as an elastic band), achieving a balance between high-strength support and localized flexible buffering.

[0065] Example 2

[0066] Based on Embodiment 1 above, this embodiment adds a lifting and adjusting mechanism to achieve the effects of adjusting the support's hardness and repairing the center depression.

[0067] See Figure 2 Specifically, the furniture (e.g., a sofa or bed frame) provided in this embodiment includes:

[0068] Furniture base 1;

[0069] The elastic support 2 described in Example 1 is located above the furniture base 1 and is used to provide upward elastic support to the human body.

[0070] The lifting and adjusting mechanism 3 is installed and fixed on the furniture base 1 and is used to support the center pad 202 of the elastic support member 2 upward.

[0071] Optionally, the lifting and adjusting mechanism 3 can be a cylinder, hydraulic cylinder, electric cylinder, or motor screw module, etc., and this embodiment does not limit it.

[0072] The furniture provided in this embodiment allows users to control the extension and retraction of the height adjustment mechanism 3, thereby adjusting the soft and hard support for the human body. The specific working process is as follows:

[0073] When the lifting adjustment mechanism 3 is lifted upward, the lifting adjustment mechanism 3 pushes the center pad 202 of the elastic support member 2 upward, which increases the initial support force of the center pad 202, and manifests as "hard support".

[0074] When the lifting adjustment mechanism 3 descends, the upward support force of the lifting adjustment mechanism 3 on the elastic support member 2 decreases, which manifests as "soft support".

[0075] Therefore, the elastic support 2 provided by this utility model can be used in conjunction with the lifting and adjusting mechanism 3 to adjust the softness and hardness of the support in order to meet diverse market demands.

[0076] Furthermore, when the elastic support 2 sags due to prolonged use, the lifting and adjusting mechanism 3 can be driven to lift the elastic support 2 upwards to repair the dent.

[0077] Optionally, a soft padding layer is also provided above the elastic support 2. The soft padding layer is in direct contact with the human body and can be made of materials such as sponge, memory foam, or down to further absorb vibration and disperse pressure, eliminating the hard feeling that the elastic support 2 may bring, making the touch soft and comfortable, while hiding the internal mechanical structure and improving the aesthetics of the furniture.

[0078] It should be noted that in this utility model, the furniture can be a sofa or a bed frame, or other furniture that needs to provide elastic support for the human body. When used as a sofa, the elastic support 2 serves as the sofa's seating support; when used as a bed frame, the elastic support 2 serves as the bed frame's slats. This utility model does not limit the specific use of the furniture.

[0079] Based on Example 1, features not explained in this example will be explained using the methods described in Example 1, and will not be repeated here.

[0080] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.

[0081] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
