Description

Technical Field

[0001] This utility model relates to the field of bedding, and more specifically, to a mattress core. Background Technology

[0002] As a home furnishing product that significantly impacts sleep quality, the support, breathability, and comfort of the mattress's core materials directly affect the user experience. Traditional hand-woven horsehair mattresses hold a significant position in the high-end home furnishing market due to the material's properties and manufacturing process. In hand-woven horsehair mattresses, the curled structure of the horsehair fibers allows them to quickly return to their original shape after compression, providing stable support. Furthermore, the numerous pores between the horsehair fibers allow air to circulate, effectively regulating the temperature and humidity inside the mattress and keeping the sleeping environment dry.

[0003] Traditional hand-woven horsehair mattresses have strict requirements on the length of horsehair fibers, requiring high-quality long horsehair with a length of ≥26cm to meet the needs of intertwining and weaving the fibers into a mesh structure during hand-weaving. Shorter fibers (<26cm) are difficult to fix due to insufficient length, and are prone to breakage or shedding during the weaving process, resulting in a loose mattress structure and poor durability. To utilize these short fibers that cannot be woven due to length limitations, current technology uses an adhesive process to bond and solidify these shorter horsehair fibers into a layered structure. For example, this can be done through spray adhesive bonding or mixing with heat-fused fibers. However, the bonded horsehair layer formed in this way lacks the dynamic cushioning structure created by natural interweaving between the fibers. Under pressure, it cannot disperse pressure through fiber deformation, resulting in poor mattress resilience, reduced breathability, and an inability to meet the mattress's elastic support requirements. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a mattress core that solves the problems of insufficient elasticity and poor support effect of the existing bonded horsehair layer in the application of mattress core.

[0005] The technical solution adopted in this utility model is a mattress inner core, comprising:

[0006] The elastic surface layer and elastic bottom layer are compressed longitudinally, and the horsehair support layer is compressed laterally between the elastic surface layer and the elastic bottom layer.

[0007] The elastic top layer provides uniform support, eliminating the unevenness caused by compression on the surface of the horsehair support layer. The elastic bottom layer works in conjunction with the elastic top layer to ensure even stress distribution on the horsehair support layer and maintain structural stability.

[0008] To optimize the elastic support of the horsehair support layer and guide its deformation under compression, thus promoting uniform support, this design includes: multiple horsehair support structures closely arranged on the same horizontal plane; the width of each horsehair support structure is the same as the width of the mattress core; and the length of each horsehair support structure is greater than its thickness.

[0009] Horsehair support structures are used to provide uniform support under lateral compression.

[0010] To improve the uniformity of support and enhance elasticity of the horsehair support layer, this design includes: multiple horsehair support structures closely arranged on the same horizontal plane; the horsehair support layer is a single integral structure; the horsehair support structures are formed by folding, so that the vertical cross-section of the horsehair support layer is wavy.

[0011] The horsehair support structure provides uniform elastic support to the horsehair support layer. Forming a single, integrated structure helps improve the structural stability of the horsehair support layer. Folding helps guide the uniform deformation of the horsehair support layer under pressure.

[0012] In order to balance cost and the molding of the horsehair support layer, the length of the horsehair fibers in the horsehair support layer in this solution is 5cm to 15cm.

[0013] To ensure that the horsehair support layer provides sufficient longitudinal elastic support, in this design, the horsehair support layer is formed by laterally compressing the original fluffy horsehair layer; the length of the horsehair support layer is 20% to 40% of the original fluffy horsehair layer.

[0014] In order to fully utilize the role of horsehair fibers and improve the elasticity and stability of the original fluffy horsehair layer, the original fluffy horsehair layer in this solution includes multiple adhesive layers stacked one on top of the other, and the horsehair fibers of the original fluffy horsehair layer are evenly distributed in each adhesive layer.

[0015] The adhesive layer is used on more adhesive surfaces to increase the fixation effect of horsehair fibers.

[0016] To enhance the elasticity of the horsehair fibers in the horsehair support layer and increase the stability of the horsehair support, in this design, the horsehair fibers pass through at least two surfaces of the adhesive layer.

[0017] To enhance comfort, in this design, the elastic surface layer and / or elastic bottom layer are wool layers; the elastic surface layer and / or elastic bottom layer include adhesive fibers and are connected to the horsehair support layer through the adhesive fibers.

[0018] The wool layer provides comfort to the top and bottom layers, while the bonding fibers bind the wool fibers in the elastic top and bottom layers and form a connection between the elastic top and bottom layers and the horsehair support layer.

[0019] To ensure the resilience and tightness of the elastic surface layer and the elastic bottom layer, in this solution, the elastic surface layer is formed by longitudinally compressing the original fluffy surface layer, and the thickness of the elastic surface layer is 50% to 70% of the thickness of the original fluffy surface layer; and / or, the elastic bottom layer is formed by longitudinally compressing the original fluffy bottom layer, and the thickness of the elastic bottom layer is 50% to 70% of the thickness of the original fluffy bottom layer.

[0020] The original fluffy surface layer is used to form an elastic surface layer through compression and shaping, and the original fluffy bottom layer is used to form an elastic bottom layer through compression and shaping.

[0021] To further improve the structural stability of the elastic surface layer and the elastic bottom layer and prevent loosening, in this solution, the elastic surface layer / or elastic bottom layer is provided with uniformly and densely distributed through channels, so that the fibers located at the upper part of the elastic surface layer / or elastic bottom layer are pulled to the bottom of the elastic surface layer / or elastic bottom layer.

[0022] Compared with existing technologies, the beneficial effects of this invention are as follows: by combining two layers compressed in different directions, the elasticity and support of the mattress core are improved. Specifically, the horsehair support layer, as the core support layer of the mattress core, achieves greater compression within a limited space through lateral compression, and utilizes the deformation of the horsehair support layer during compression to convert the lateral elastic compressive force into longitudinal support force. This design effectively enhances the elasticity of the horsehair support layer, which was inherently inelastic before compression, through the structural action.

[0023] Furthermore, by guiding the integrated horsehair support layer to compress into a wave shape, not only is the conversion efficiency of lateral compression force into longitudinal support force improved, but the overall stability of the horsehair support layer is also increased. Additionally, gaps are formed throughout both sides, increasing the breathability of the horsehair support layer itself. Combined with the longitudinally compressed elastic top and bottom layers, this not only ensures even stress distribution on the horsehair support layer during use but also eliminates any unevenness, enhancing comfort.

[0031] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment is a mattress core, including: a longitudinally compressed elastic surface layer 100 and an elastic bottom layer 200, and a transversely compressed horsehair support layer 300 disposed between the elastic surface layer 100 and the elastic bottom layer 200.

[0034] By altering the structure of the horsehair layer, a laterally compressed horsehair support layer 300 is formed. This causes the horsehair fiber layer 312 to deform laterally under pressure, forming a longitudinally compact structure. This structure facilitates longitudinal elastic support, thereby increasing the elasticity of the horsehair support layer 300 within a limited height space. Combined with the longitudinally compressed elastic surface layer 100 and elastic bottom layer 200, this forms complete vertical support, eliminating the unevenness caused by localized protrusions and dispersed support in the vertical direction of the laterally compressed horsehair support layer 300. This results in more even support, improved comfort, and prevents localized collapse, effectively addressing the problem of insufficient elasticity in the bonded horsehair layer.

[0035] like Figure 3 As shown, the horsehair support layer 300 includes: a plurality of horsehair support structures 310 closely arranged on the same horizontal plane; the width of the horsehair support structure 310 is the same as the width of the mattress core; the length of the horsehair support structure 310 is greater than its thickness.

[0036] Under compression, the horsehair support layer 300 provides elastic support through multiple closely arranged horsehair support structures 310. Each horsehair support structure 310 can independently and evenly bear longitudinal pressure, and by coordinating with each other to share the pressure, it avoids any support gaps. Furthermore, the support structure itself possesses longitudinal support force and elasticity, further enhancing the overall elastic support and recovery function.

[0037] like Figure 2 As shown, the horsehair support layer 300 includes: a plurality of horsehair support structures 310 closely arranged on the same horizontal plane; the horsehair support layer 300 is an integral structure; the horsehair support structures 310 are formed by folding so that the vertical cross-section of the horsehair support layer 300 is wavy.

[0038] By forming a wavy, integrated structure, the deformation of the horsehair support layer 300 during lateral compression can be effectively guided, promoting a uniform distribution of the compact structure. Furthermore, the integrated structure enhances the interrelationship between the horsehair support structures 310, enabling adjacent horsehair support structures 310 to form continuous and interactive support, eliminating weak support areas. The wavy structure allows for the formation of regularly and tightly arranged horsehair support structures 310 during lateral compression of the horsehair support layer 300, optimizing the unfolding state of the horsehair support layer 300 under pressure and making it easier to form breathable gaps, thus increasing breathability.

[0039] The horsehair support layer 300 has horsehair fibers 312 with a length of 5cm to 15cm.

[0040] This size of horsehair fiber 312 is cost-effective and avoids the unevenness that can occur during layering due to excessive length. The structure of the horsehair support layer 300 allows for the full utilization of short fibers that are unusable in traditionally hand-woven horsehair layers, and provides sufficient elastic support through the mechanism, thus improving efficiency and reducing costs. The horsehair fibers 312 in the horsehair support layer 300 do not need to interweave to form a stable support structure, while compression provides sufficient elasticity, thereby increasing material utilization.

[0041] The horsehair support layer 300 is formed by laterally compressing the original fluffy horsehair layer; the length of the horsehair support layer 300 is 20% to 40% of the original fluffy horsehair layer.

[0042] This compression level ensures that the horsehair support layer 300 provides sufficient lateral support. At this compression level, the gaps between the compressed horsehair fibers 312 decrease, reducing fiber misalignment during deformation and providing sufficient longitudinal compressible space to meet the dynamic adjustment requirements of the horsehair support layer 300 under pressure. A balance is achieved between compression cost and compression effect.

[0043] like Figure 5 As shown, the original fluffy horsehair layer includes multiple adhesive layers 311 stacked one on top of the other, and the horsehair fibers 312 of the original fluffy horsehair layer are evenly distributed in each adhesive layer 311.

[0044] The stacking of multiple adhesive layers 311 allows for diverse fixation of the horsehair fibers 312, increasing the bonding and fixation of the horsehair fibers 312 between layers. Furthermore, the multi-layered design fully releases the elasticity of the horsehair fibers interspersed within. Whether it's a single adhesive layer 311 or multiple adhesive layers 311, the effectiveness of the horsehair fibers 312 increases with the number of layers bonded.

[0045] like Figure 6 As shown, the horsehair fibers 312 pass through at least two sides of the adhesive layer 311.

[0046] This configuration of the horsehair fibers 312 helps to enhance the elastic support force within the horsehair support layer 300. By penetrating at least two surfaces, the horsehair fibers 312 reduce planar distribution and increase three-dimensional distribution, extending beyond the planar plane into a three-dimensional structure. This allows for greater elasticity under multi-angle stress, leveraging the inherent elasticity of the horsehair fibers 312. Furthermore, this configuration not only increases the stability of the adhesive layer 311 itself but also enhances the bonding strength and stability between multiple adhesive layers 311.

[0047] The elastic surface layer 100 and / or the elastic bottom layer 200 are wool layers; the elastic surface layer 100 and / or the elastic bottom layer 200 include adhesive fibers and are connected to the horsehair support layer 300 through the adhesive fibers.

[0048] By bonding the fibers, not only can the wool fibers in the wool layer be bonded together, but the bonding between the elastic surface layer 100 and the elastic bottom layer 200 and the horsehair support layer 300 can also be satisfied at one time. This ensures that the gap between the fibers is maintained after bonding, without damaging the structural characteristics of the wool fibers or horsehair fibers 312 themselves, and also avoids the use of glue or adhesives.

[0049] The elastic surface layer 100 is formed by longitudinally compressing the original fluffy elastic surface layer 100, and the thickness of the elastic surface layer 100 is 50% to 70% of the thickness of the original fluffy surface layer; and / or, the elastic bottom layer 200 is formed by longitudinally compressing the original fluffy elastic bottom layer 200, and the thickness of the elastic bottom layer 200 is 50% to 70% of the thickness of the original fluffy elastic bottom layer 200.

[0050] By further limiting the compression ratio of the elastic surface layer 100 and the elastic bottom layer 200, the elastic effect and structural stability are ensured. The gaps between the fibers in the elastic surface layer 100 and the elastic bottom layer 200 are reduced, fiber misalignment is decreased, and fiber stability is improved. This results in a small deformation of the mattress core during long-term use, reducing the risk of collapse and making the overall shape stable and elastic.

[0051] The elastic surface layer 100 / or elastic bottom layer 200 is provided with uniformly and densely distributed through channels, so that the fibers located in the upper part of the elastic surface layer 100 are pulled to the bottom of the elastic surface layer 100.

[0052] By physically penetrating to form a through channel, the fibers are directionally stretched and interlaced, forming a tight cross-layered connection between the upper and lower fibers, constructing a constraint network, effectively suppressing fiber displacement and delamination risks, while enhancing the overall shear and compression resistance.

[0053] Example 2

[0054] A mattress core includes: a longitudinally compressed elastic surface layer 100 and an elastic bottom layer 200, and a transversely compressed horsehair support layer 300 disposed between the elastic surface layer 100 and the elastic bottom layer 200.

[0055] The vertical direction corresponds to the direction of force applied during mattress use. The horizontal direction is horizontal. Lateral compression causes the horsehair support layer 300 to deform within a limited height, forming an irregular, protruding structure. When subjected to vertical pressure during use, the horsehair support layer 300 converts the vertical compression deformation into lateral extension, transforming the elastic deformation caused by lateral force into vertical support. This improves the resilience and support of the horsehair support layer 300 within the mattress core. Furthermore, the tight structure formed by the pressure of the horsehair support layer 300 creates transversely penetrating breathable gaps, enhancing its breathability.

[0056] The horsehair support layer 300 includes: a plurality of horsehair support structures 310 closely arranged on the same horizontal plane; the width of the horsehair support structure 310 is the same as the width of the mattress core; the length of the horsehair support structure 310 is greater than its thickness.

[0057] In this embodiment, the horsehair support structure 310 is a cuboid, and the horsehair support structures 310 are arranged vertically and closely together. The horsehair support structures 310 are all the same size.

[0058] The horsehair support layer 300 includes: multiple horsehair support structures 310 closely arranged on the same horizontal plane; the horsehair support layer 300 is an integral structure; the horsehair support structures 310 are formed by folding so that the vertical cross-section of the horsehair support layer 300 is wavy.

[0059] In this embodiment, the horsehair support structure 310 is part of the horsehair support layer 300. The wavy integrated structure is formed by first folding and then compressing the original fluffy horsehair layer, then curing it by heating, and then combining it with the elastic surface layer 100 and the elastic bottom layer 200.

[0060] The length of the horsehair fibers 312 in the horsehair support layer 300 is 5cm to 15cm. Specifically, it can be 5cm to 10cm.

[0061] The horsehair support layer 300 is formed by laterally compressing the original fluffy horsehair layer; the length of the horsehair support layer 300 is 20% to 40% of the original fluffy horsehair layer.

[0062] In this embodiment, the length of the horsehair support layer 300 can be 30% of the original fluffy horsehair layer. This compression amount can be the change between the length of the original fluffy horsehair layer before folding and compression and the length after folding and compression.

[0063] The original fluffy horsehair layer includes multiple adhesive layers 311 stacked one on top of the other, and the horsehair fibers 312 of the original fluffy horsehair layer are evenly distributed in each adhesive layer 311.

[0064] In this embodiment, the mass ratio of the original fluffy horsehair layer to the horsehair fiber 312 is 10:(7 to 9). The adhesive layer 311 is composed of adhesive fibers.

[0065] Horsehair fibers 312 pass through at least two sides of an adhesive layer 311.

[0066] In this embodiment, the horsehair fibers 312 can pass through two or more adhesive layers 311, or multiple times, and be exposed on more surfaces. They can also pass through multiple adhesive layers 311 and be exposed on the surface of different adhesive layers 311. The exposed horsehair fibers 312 are bonded to the surface of the adhesive layer 311.

[0067] The elastic surface layer 100 and / or the elastic bottom layer 200 are wool layers; the elastic surface layer 100 and / or the elastic bottom layer 200 include adhesive fibers and are connected to the horsehair support layer 300 through the adhesive fibers.

[0068] The bonding fibers are embedded in the wool fibers in a uniformly dispersed manner. After being combed into layers and then compressed by heat, a stable wool layer with a compression effect can be formed. In this embodiment, both the elastic surface layer 100 and the elastic bottom layer 200 are made of wool fibers and bonding fibers. The horsehair support layer 300 is made of horsehair fibers 312 and bonding fibers. At the same time, the horsehair support layer 300 is also bonded to the elastic surface layer 100 and the elastic bottom layer 200 respectively by bonding fibers.

[0069] The elastic surface layer 100 is formed by longitudinally compressing the original fluffy elastic surface layer 100, and the thickness of the elastic surface layer 100 is 50% to 70% of the thickness of the original fluffy surface layer; and / or, the elastic bottom layer 200 is formed by longitudinally compressing the original fluffy elastic bottom layer 200, and the thickness of the elastic bottom layer 200 is 50% to 70% of the thickness of the original fluffy elastic bottom layer 200.

[0070] In this embodiment, the elastic surface layer 100 and the elastic bottom layer 200 are formed by longitudinal compression followed by heating and curing.

[0071] like Figure 4 As shown, the elastic surface layer 100 / or elastic bottom layer 200 is provided with uniformly and densely distributed through channels, so that the fibers located in the upper part of the elastic surface layer 100 / or elastic bottom layer 200 are drawn to the bottom of the elastic surface layer 100 / or elastic bottom layer 200.

[0072] In this embodiment, the through-channel is formed by a needle punching process. The width of the horsehair support structure 310 is a, the length of the horsehair support structure 310 is b, and the thickness of the horsehair support structure 310 is c.
