Description

Technical Field

[0001] This utility model relates to the field of home furnishing technology, and in particular to a double composite cushion, a triple composite cushion, a multi-composite cushion, a sofa, and a mattress. Background Technology

[0002] As a common type of seating furniture, the comfort and durability of sofas largely depend on the performance of their seat cushions. Currently, most mainstream sofa products on the market use foamed sponge as the core filling material for their seat cushions. This type of material is foamed and molded in a single process in a mold, offering advantages such as simple processing and relatively low cost.

[0003] In practice, the inherent technical flaws of this solid seat cushion structure have gradually become apparent. Under long-term, repeated loads, the polymer structure of solid foam material is prone to changes due to stress fatigue, leading to a decrease in the material's resilience, also known as "insufficient rebound." This causes the seat cushion surface to easily "collapse" after a period of use. In areas where the body's pressure is concentrated, the foam is more easily compressed and loses its elasticity. Collapse not only severely affects the sofa's aesthetics but also leads to uneven support, reducing the user experience.

[0004] Therefore, it is necessary to improve the existing seat cushion to enhance its resistance to collapse and thus extend its service life.

[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 a double composite cushion, a triple composite cushion, a multi-composite cushion, a sofa, and a mattress that can effectively solve the problem of existing seat cushions easily collapsing.

[0007] To achieve the above objectives, firstly, this utility model provides a dual composite pad comprising:

[0008] A solid support body, which encloses and forms an inner cavity of the main body;

[0009] A honeycomb support core is located within the inner cavity of the main body and surrounds several transverse buffer holes arranged in a honeycomb pattern to provide vertical deformation elastic support.

[0010] Optionally, the honeycomb support core includes several layers of elastic support components arranged sequentially from top to bottom, and the elastic support components include an upper wave member and a lower wave member located below the upper wave member;

[0011] The crests of the two wave-shaped components are aligned vertically to form the transverse buffer hole; the troughs of the two wave-shaped components are close to each other and fixed together.

[0012] Optionally, a straight connecting member is provided between two adjacent wave-shaped components.

[0013] Optionally, the elasticity of the upper wave member is greater than that of the lower wave member belonging to the same layer of elastic support assembly, and the elasticity of the straight connector is between that of the upper wave member and the lower wave member.

[0014] Optionally, the straight connector and the adjacent trough portion are bonded, ultrasonically welded, or thermo-pressed.

[0015] Optionally, the top and / or bottom of the inner cavity of the main body is an open structure, and the open structure is provided with a sealing non-woven fabric for sealing the open structure.

[0016] Secondly, a three-composite pad is provided, comprising:

[0017] The dual composite pad described above has a core cavity inside.

[0018] A plurality of spring cylinders are disposed within the inner cavity of the core, for providing upward elastic support to the top surface of the inner cavity of the core.

[0019] Thirdly, a multi-composite pad is provided, including any one of the aforementioned dual-composite pads, and a triple-composite pad located below the dual-composite pad.

[0020] Fourthly, a composite sofa is provided, comprising a seat cushion and a sofa back, wherein the seat cushion comprises any of the aforementioned double composite cushion, triple composite cushion, or multi-composite cushion.

[0021] Fifthly, a composite mattress is provided, comprising a mattress core and a mattress cover fitted over the mattress core, wherein the mattress core comprises any of the aforementioned double composite mattress body, triple composite mattress body, or multi-composite mattress body.

[0022] The beneficial effects of this utility model are as follows: It provides a double composite cushion body, a triple composite cushion body, a multi-composite cushion body, a sofa, and a mattress. The solid support body encloses and forms a stable inner cavity to constrain and prevent lateral displacement of the internal honeycomb support core during use. The honeycomb support core, as the core component that bears human body pressure and provides elastic feedback, is enclosed to form several lateral buffer holes arranged in a honeycomb pattern.

[0023] When pressure is applied by the human body, the honeycomb structure (i.e., the lateral buffer holes) of the honeycomb support core undergoes elastic deformation under vertical pressure, with the hole walls bending or contracting in the vertical direction. This efficiently absorbs and disperses stress, providing soft and elastic primary support for the human body. During this process, the outer solid support body ensures that the honeycomb support core can work stably and consistently within its predetermined internal cavity, preventing lateral instability and ensuring that it deforms stably and consistently only within the predetermined internal cavity.

[0024] When the pressure is released, the honeycomb support core relies on the elasticity of its material to drive the transverse buffer holes to return to their original shape, generating a rebound force, thereby restoring the deformation and preventing collapse.

[0025] Therefore, the double composite cushion, triple composite cushion, multi-composite cushion, sofa and mattress provided by this utility model provide external shaping and lateral constraint through the solid support body, and provide efficient cushioning and rebound through the honeycomb structure of the honeycomb support core, thereby solving the problem of easy collapse of existing seat cushions.

[0048] Example 1

[0049] See Figure 1 and Figure 2 First, we will give a detailed introduction to the dual composite pad 200a, which is the core of the solution.

[0050] In this embodiment, the dual composite pad 200a includes:

[0051] A solid support body 1, which encloses and forms an inner cavity 101;

[0052] The honeycomb support core 2 is located inside the main body cavity 101 and surrounds several transverse buffer holes 201 arranged in a honeycomb pattern to provide vertical deformation elastic support.

[0053] Optionally, the solid support body 1 is made of sponge or latex, etc.

[0054] In this embodiment, the solid support body 1 encloses a stable inner cavity 101. The main function of this solid support body 1 is not to directly provide primary elastic support, but rather to provide external shaping for the entire pad, maintain its overall shape, and crucially constrain and prevent lateral displacement of the internal honeycomb support core 2 during use. The honeycomb support core 2 is precisely positioned within the aforementioned inner cavity 101. The honeycomb support core 2 is the core component that bears the pressure of the human body and provides elastic feedback; its unique structure lies in the enclosed formation of several lateral buffer holes 201 arranged in a honeycomb pattern.

[0055] When pressure is applied by the human body, the honeycomb structure (i.e., the transverse buffer holes 201) of the honeycomb support core 2 undergoes elastic deformation under vertical pressure, and the hole walls bend or contract in the vertical direction, thereby efficiently absorbing and dispersing stress and providing soft and elastic primary support for the human body. During this process, the outer solid support body 1 ensures that the honeycomb support core 2 can work stably and consistently within its preset main body cavity 101 space, preventing lateral instability and ensuring that it deforms stably and consistently only within the preset main body cavity 101 space.

[0056] When the pressure is released, the honeycomb support core 2 relies on the elasticity of its material to drive the transverse buffer hole 201 to return to its original shape, generating a rebound force, thereby restoring the deformation and preventing collapse.

[0057] Therefore, the dual composite cushion 200a provided by this utility model provides external shaping and lateral constraint through the solid support body 1, and provides efficient buffering and rebound through the honeycomb structure of the honeycomb support core 2, thereby solving the problem of easy collapse of the existing seat cushion 100A.

[0058] In this embodiment, the honeycomb support core 2 includes several layers of elastic support components 202 arranged sequentially from top to bottom. The elastic support component 202 includes an upper wave member 2021 and a lower wave member 2022 located below the upper wave member 2021.

[0059] The crests of the two wave-shaped components are aligned vertically to enclose and form the transverse buffer hole 201; the troughs of the two wave-shaped components are close to each other and fixedly connected.

[0060] Under pressure, the crest regions of the upper wave member 2021 and the lower wave member 2022 deform in concert toward the center, while the transverse buffer holes 201 contract to absorb energy; the trough fixing points ensure stable interlayer connections and prevent component separation. The multi-layer elastic support component 202 enhances buffer uniformity through the wave member structure, and the honeycomb arrangement of the transverse buffer holes 201 further improves stress dispersion capability, making the structure more stable.

[0061] Optionally, the elasticity of the upper wave member 2021 is greater than that of the lower wave member 2022, which belongs to the same layer of elastic support assembly 202. Because the elasticity of the upper wave member 2021 is greater than that of the lower wave member 2022, when pressure is applied, the upper wave member 2021 first undergoes a larger deformation to provide an initial soft touch, while the lower wave member 2022 subsequently provides stronger support, forming a gradient elastic response. This achieves an elastic transition from soft to hard from top to bottom, improving comfort and avoiding local stress concentration.

[0062] Furthermore, a straight connecting member 203 is provided between two adjacent wave members, and the elasticity of the straight connecting member 203 is between that of the upper wave member 2021 and the lower wave member 2022.

[0063] In this embodiment, the upper wave component 2021 is an elastic fiber component, which is a three-dimensional mesh component made of fibers (polyester spiral fiber, high elastic polyester fiber, natural latex fiber, etc.) with high resilience and stretchability through specific processes (such as hot air bonding, needle punching, 3D weaving, etc.).

[0064] The lower wave component 2022 is a non-elastic fiber component. Here, "non-elastic" is a relative concept, as opposed to "elastic fiber component". It refers to a three-dimensional mesh component made of rigid fibers (hard cotton felt, high-density nonwoven fabric, glass fiber / carbon fiber, etc.) interwoven through specific processes (such as hot air bonding, needle punching, 3D weaving, etc.). Its core function is not to provide significant compression deformation, but to provide support and shaping.

[0065] The straight connector 203 is a composite of elastic and inelastic fibers, the specific ratio of which can be determined according to the required setup. Under pressure, the straight connector 203 acts as an elastic transition layer, coordinating the deformation of the upper and lower corrugated components 2022, making force transmission smoother. The upper corrugated component 2021 (elastic fiber component) and the lower corrugated component 2022 (inelastic fiber component) achieve material property gradient matching through the straight connector 203 (elastic / inelastic fiber composite). It can be understood that the straight connector 203 can reduce interlayer elastic abrupt changes, prevent interface stress concentration, and enhance the overall structural integrity and durability.

[0066] In this embodiment, the straight connector 203 and the adjacent trough portion are fixed together by means of bonding, ultrasonic welding, or hot pressing welding to ensure that the connection point of the elastic support component 202 does not loosen during deformation. This utility model does not limit this.

[0067] Optionally, the top and / or bottom of the inner cavity 101 of the main body is an open structure, and the open structure is provided with a sealing non-woven fabric 3 for sealing the open structure. The non-woven fabric allows air to circulate, but prevents foreign objects from entering the inner cavity 101 of the main body, thereby improving the breathability of the pad, reducing moisture and heat accumulation, and keeping the inside clean and enhancing hygiene.

[0068] In summary, the dual composite pad 200a provided in this embodiment has the following advantages:

[0069] ① First, the solid support body 1 encloses and forms the inner cavity 101 of the main body and provides external shaping, effectively constraining the lateral displacement of the honeycomb hole support core 2 and ensuring the overall stability of the structure; then, the honeycomb arrangement of the lateral buffer holes 201 of the honeycomb hole support core 2 generates elastic deformation under vertical pressure, efficiently absorbs and disperses stress, and provides soft and elastic main support.

[0070] ② By setting the upper wave component 2021 to have a greater elasticity than the lower wave component 2022, a gradient elastic response is formed, realizing an elastic transition from soft to hard from top to bottom, improving comfort and avoiding stress concentration.

[0071] ③ A straight connector 203 with an elasticity between adjacent corrugated components is set between them to coordinate the deformation of the upper and lower layers, reduce the elastic abrupt change between layers, and enhance the overall structure and durability.

[0074] The following sections will introduce the three-composite cushion 200, multi-composite cushion, sofa, and mattress one by one.

[0076] See Figure 3 The three-composite pad 200 provided in this embodiment includes:

[0077] In any of the embodiments described in Example 1, the dual composite pad 200a has a core cavity inside.

[0078] A plurality of spring sleeves 200b are disposed within the inner cavity of the core, for providing upward elastic support to the top surface of the inner cavity of the core.

[0079] The triple composite pad 200 provided in this embodiment, after adding a spring cylinder 200b to the double composite pad 200a, provides additional upward elastic support to the top surface of the core cavity when pressure is applied, working in conjunction with the honeycomb support core 2. The spring cylinder 200b enhances the overall support force and resilience, making it suitable for high-load scenarios and further preventing collapse.

[0080] (3) Multi-composite cushion

[0081] See Figure 4 The multi-composite pads provided in this embodiment include the double composite pad 200a described in any of Embodiment 1, and the triple composite pad 200 located below the double composite pad 200a as described above.

[0082] The multi-composite pad provided in this embodiment places a dual-composite pad 200a above a triple-composite pad 200. The pressure is initially buffered by the dual-composite pad 200a, and then supported by the spring cylinder 200b of the triple-composite pad 200, resulting in multi-layered composite synergistic deformation. Combining the advantages of the dual-composite pad 200a and the triple-composite pad 200, it provides more comprehensive gradient support and anti-collapse capability, adapting to diverse needs.

[0083] (4) Composite sofa

When a person lies down, the mattress core and spring coils distribute body pressure through a honeycomb-hole support core. This composite mattress structure provides even support, prevents localized sagging, improves sleep experience, and extends mattress life.
