Description

Technical Field

[0001] This application relates to the field of furniture technology, and more particularly to a spring mattress and a mattress. Background Technology

[0002] Traditional mattresses often use a uniform, homogeneous arrangement. While some mattresses on the market have three, five, or seven zones, each zone uses springs of different diameters or coil counts to create a ergonomic design that meets the varying support needs of different body types. However, these solutions are often only suitable for a specific group of people and cannot be applied to individuals with different body shapes. Furthermore, they fail to provide precise dynamic support when turning over or sleeping on one's side at night.

[0003] Therefore, it is necessary to design a spring mattress and a mattress that can solve the above-mentioned technical problems. Utility Model Content

[0004] This application provides a spring mattress and a mattress that can meet the needs of people with different body types.

[0005] According to a first aspect of the embodiments of this specification, a spring mattress is provided, which includes, from top to bottom, a first support layer, a second support layer and a third support layer, wherein the elastic coefficient of the first support layer is less than the elastic coefficient of the second support layer, and the elastic coefficient of the second support layer is less than the elastic coefficient of the third support layer; along the length direction of the spring mattress, the height of the first support layer is the same, and the heights of the second support layer and the third support layer are arranged in a curved manner.

[0006] Furthermore, along the length of the spring mattress, the spring mattress sequentially includes a head support area, a shoulder and back support area, a waist support area, a hip support area, a thigh support area, and a calf support area.

[0007] Furthermore, the elastic coefficients of the head support area, the waist support area, and the thigh support area are the same, and the elastic coefficient of the thigh support area is smaller than that of the hip support area.

[0008] Furthermore, the elastic coefficient of the shoulder and back support area is the same as that of the calf support area, while the elastic coefficient of the calf support area is smaller than that of the thigh support area.

[0009] Furthermore, the spring bed net includes multiple independent pocket springs, which are arranged in a matrix and are bonded and fixed between adjacent independent pocket springs.

[0010] Furthermore, the independent spring includes an outer spring, a middle spring, and an inner spring; the middle spring is sleeved outside the inner spring, and the outer spring is sleeved outside the middle spring; the bottoms of the outer spring, the middle spring, and the inner spring are located in the same plane;

[0011] The outer spring forms the first support layer; the middle spring forms the second support layer; and the inner spring forms the third support layer.

[0012] Furthermore, the elastic coefficient of the outer spring is smaller than that of the middle spring, and the elastic coefficient of the middle spring is smaller than that of the inner spring.

[0013] Furthermore, the spring constant of the independent pocket spring depends on at least one of the following parameters: wire diameter, number of loops, diameter, waist diameter, pitch, and preload height.

[0014] Furthermore, the wire diameter of the external spring ranges from 1.7mm to 2.0mm, the number of turns ranges from 8 to 10, and the preload height ranges from 16cm to 18cm.

[0015] The wire diameter of the central spring ranges from 2.1mm to 2.3mm, the number of coils ranges from 6 to 8, and the preload height ranges from 10cm to 14cm.

[0016] The internal spring has a wire diameter ranging from 2.4mm to 2.6mm, a number of coils ranging from 4 to 6, and a preload height ranging from 5cm to 9cm.

[0017] According to a second aspect of the embodiments of this specification, a mattress is provided, comprising the spring bed net described in the first aspect above.

[0018] This application has the following beneficial effects: By setting up three support layers, this application can meet the usage needs of people with different body types. For example, for people with small body size, the first support layer can provide support; for people with medium body size, the first support layer and part of the second support layer provide support; for people with large body size, the first support layer, the second support layer and the third support layer together provide support.

[0026] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0028] The embodiments described in this specification will now be described in detail.

[0029] Reference Figure 1 As shown, this application discloses a spring mattress, which includes a first support layer 10, a second support layer 20, and a third support layer 30 from top to bottom. The elastic coefficient of the first support layer 10 is less than that of the second support layer 20, and the elastic coefficient of the second support layer 20 is less than that of the third support layer 30. In other embodiments, only two, four, or more support layers may be provided; no specific limitation is made here.

[0030] In this way, the needs of people with different body types can be met. For example, for people with small body sizes, the first support layer 10 can provide support. For people with medium body sizes, the first support layer 10 is compressed first, and after the upper surface of the first support layer 10 contacts the upper surface of the second support layer 20, further support is provided through a portion of the second support layer 20. For people with large body sizes, support is provided by sequentially compressing the first support layer 10, the second support layer 20, and the third support layer 30.

[0031] Considering the different support needs of different areas of the human body, and to better conform to the curves of the human body, the first support layer 10 has the same height along the length of the spring mattress, while the second support layer 20 and the third support layer 30 have different heights. Figure 1 The S-shaped curve shown in the image allows the support force exerted by the user on the spring mattress to transition smoothly, precisely conforming to the body's curves and adapting to various sleeping positions.

[0032] Specifically, along the length of the spring mattress, the spring mattress sequentially includes a head support area 100, a shoulder and back support area 200, a lumbar support area 300, a hip support area 400, a thigh support area 500, and a calf support area 600.

[0033] In a preferred embodiment, the head support area 100, the waist support area 300, and the thigh support area 500 have the same elastic coefficient. The shoulder and back support area 200 has the same elastic coefficient as the calf support area 600. The calf support area 600 has a smaller elastic coefficient than the thigh support area 500, and the thigh support area 500 has a smaller elastic coefficient than the buttock support area 400.

[0034] Specifically, the 400mm spring in the hip support area has a high preload height, fewer coils, thicker wire diameter, and shorter height, resulting in ample spring tension and overall high rigidity for stable hip support. The 300mm spring in the lumbar support area has a moderate preload height, number of coils, wire diameter, and height, with relatively ample spring tension and a higher overall rigidity, effectively supporting the lower back. The 200mm shoulder and back support area and the 600mm calf support area have slightly lower preload height, more coils, thinner wire diameter, and higher height, with slightly lower spring tension and a lower overall rigidity, effectively relieving pressure and ensuring the spine maintains its natural curvature during sleep. The preload height mentioned here refers to the external force or deformation applied to the spring before installation, ensuring it reaches the required height or strength during operation.

[0035] Reference Figure 2 As shown, the spring bed net includes multiple independent pocket springs 40, which are arranged in a matrix and adjacent pocket springs 40 are bonded and fixed to form a spring bed net.

[0036] The individual pocket springs 40 are cylindrical and spirally arranged, with multiple individual pocket springs 40 arranged vertically among them. The spring constant of the individual pocket springs 40 depends on at least one of the following parameters: wire diameter, number of rings, diameter, web diameter, pitch, and preload height.

[0037] The shape of the independent pocket spring 40 is not limited to the standard cylindrical shape. In some variant embodiments, it may be in the shape of a drum (the diameter at both ends is larger than the diameter at the middle), a barrel (the diameter at the top end is smaller than the diameter at the bottom end), or a cone, etc. These shapes will affect the compression characteristics and stability of the spring, thereby fine-tuning the support feel.

[0038] In addition, the helix direction of the independent pocket spring 40 can be left-handed or right-handed. In the same spring bed network, springs with different helix directions can be arranged alternately to enhance the stability and anti-interference ability of the overall structure.

[0039] In this embodiment, the independent spring 40 includes an outer spring 41, a middle spring 42, and an inner spring 43. The middle spring 42 is sleeved outside the inner spring 43, and the outer spring 41 is sleeved outside the middle spring 42. The bottoms of the outer spring 41, the middle spring 42, and the inner spring 43 are located in the same plane. The tops of the outer spring 41 are located in the same plane, and the heights of the middle spring 42 and the inner spring 43 are approximately the same. Figure 1 The S-shaped curve shown in the figure forms a first support layer 10 through an outer spring 41, a second support layer 20 through a middle spring 42, and a third support layer 30 through an inner spring 43.

[0040] In another embodiment, the three support layers can also be physically separate independent spring layers, such as a first independent pocket spring layer, a second independent pocket spring layer, and a third independent pocket spring layer stacked sequentially from top to bottom. The parameters (wire diameter, number of coils, preload height, etc.) of each spring layer are set independently to achieve a gradient change in the elastic coefficient, and the layers can be connected and fixed by means of non-woven fabric, hot melt adhesive, or physical fastening.

[0041] The elastic coefficient of the outer spring 41 is smaller than that of the middle spring 42, and the elastic coefficient of the middle spring 42 is smaller than that of the inner spring 43. Thus, the spring mattress can provide differentiated performance under different loads or compression conditions, thereby balancing comfort, stability, and safety.

[0042] In this embodiment, the outer spring 41 has a wire diameter ranging from 1.7mm to 2.0mm, a coil count ranging from 8 to 10, and a preload height ranging from 16cm to 18cm. The middle spring 42 has a wire diameter ranging from 2.1mm to 2.3mm, a coil count ranging from 6 to 8, and a preload height ranging from 10cm to 14cm. The inner spring 43 has a wire diameter ranging from 2.4mm to 2.6mm, a coil count ranging from 4 to 6, and a preload height ranging from 5cm to 9cm.

[0043] Because the independent pocket springs 40 employ a nested spring system design, they provide dynamic adaptive support for users during turning over. When lying on their back, the outer spring 41 within the first support layer 10 of the hip support area 400 effectively sinks, while the middle spring 42 within the second support layer 20 provides stable support. When sleeping on their side, the outer spring 41 within the first support layer 10 of the shoulder and back support area 200 effectively sinks, while the middle spring 42 within the second support layer 20 provides stable support. Thus, the nested spring system ensures that the spine maintains its natural curvature whether lying on their back or side, meeting the needs of people with various body types.

[0044] Furthermore, when the user turns over or applies pressure locally, only the springs in the compressed area deform and activate the corresponding support layer, while the springs in the non-compressed areas remain unchanged. This greatly reduces the transmission of motion, making the spring mattress mesh respond more quickly and accurately to changes in the user's posture, achieving a "dynamic fit" effect.

[0045] The spring mattress in this application uses independent pocket springs 40, which enables completely independent operation between the springs, effectively isolating the transmission of motion and stillness, greatly reducing noise interference during sleep, and creating a quiet and comfortable sleep atmosphere.

[0046] This application also discloses a mattress comprising the aforementioned spring mesh. Furthermore, the mattress may have a multi-layered structure arranged above, below, or simultaneously above and below the spring mesh to meet different usage needs; no specific limitations are imposed herein.

[0047] In one embodiment, the upper structure may include a combination of one or more materials such as memory foam, latex, high-resilience foam, gel padding, 3D mesh, and wool felt. These comfort layers can work in conjunction with the underlying spring mattress to adjust the firmness and contour of the mattress. For example, laying a layer of soft memory foam on a firm spring mattress can provide both sufficient deep support and a comfortable shallow wrapping feel. The sides of the mattress may be fitted with high-density foam trim or an edge support system to enhance edge support, prevent slippage, and increase the usable surface area.

[0048] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
