Description

Technical Field

[0001] The utility model belongs to the field of bedding, and in particular relates to a partitioned pocket spring string, a cushion core and a mattress. Background Art

[0002] Existing spring mattresses typically utilize pocket springs arranged side by side. These pocket springs are typically independent and unconnected to their surrounding pocket springs, resulting in uneven load distribution and prone to shifting and deformation during use. This can cause the mattress to sag or collapse in certain areas, leading to an uneven surface and impacting sleep comfort and support. Individually arranged pocket spring mattresses require regular flipping or rotation to ensure even force on each spring and extend their lifespan. This is a tedious operation and requires additional time and effort to maintain. Utility Model Content

[0003] In view of the problem that existing spring mattresses using independent pocket springs are prone to displacement and deformation, the utility model provides a partitioned pocket spring string, a mattress core and a mattress, which connect the pocket springs to each other and link adjacent positioning tubes by providing connecting parts and hot-melt connecting seams to avoid large displacement and deformation.

[0004] The technical solution adopted by the utility model is as follows: a partitioned bagged spring string, including a plurality of positioning cylinders arranged side by side, each of which is provided with a tower spring, and a connecting portion is provided between adjacent positioning cylinders, and a hot-melt connection seam is provided on the connecting portion to form a hot-melt connection, and the hot-melt connection seam is Y-shaped.

[0005] A connecting portion is provided to connect adjacent positioning tubes to form a reliable connection and a constraint to prevent the bagged spring string from causing large displacement and deformation; force can be applied along the Y-shaped hot-melt connection seam to separate adjacent positioning tubes, making it convenient to set the number of positioning tubes according to needs, and the operation is simple and convenient.

[0006] Furthermore, at least one of the connecting parts is provided with an opening, and the opening is located above the hot melt connection seam. Providing an opening on the connecting part can reduce the connection strength between adjacent positioning tubes, and facilitate the formation of areas with differentiated support effects.

[0007] Furthermore, the zoned pocket spring string has alternating hard and moderate zones. The openings in the moderate zones have a depth of 0.5-1 cm, while the hard zones have no openings. The hard zones have no openings, resulting in a stronger connection and higher support strength. The moderate zones have shallower openings, which reduces the connection and lowers the support strength. The alternating hard and moderate zones can meet different usage requirements.

[0008] Furthermore, the zoned pocket spring string also has a soft zone located between the medium and hard zones. The openings in the soft zone have a depth of 1-2 cm. The opening depth of the soft zone is greater than that of the medium zone, so the support provided by the positioning tubes in the soft zone is weaker than that in the medium zone. This creates three soft and hard support zones to meet different usage requirements.

[0009] Furthermore, the depth of the opening between two adjacent positioning cylinders is set differently. The opening depth preferably changes gradually, especially in a wave-like configuration, to meet differentiated usage requirements.

[0010] Furthermore, the tower spring is a helical spring body comprising a truncated conical section and a cylindrical section arranged from top to bottom, the truncated conical section being integrally connected to the cylindrical section. The cylindrical section at the bottom provides better support, while the truncated conical section at the top has a smaller contact surface with the human body, allowing for directional adjustment based on different force directions.

[0011] Furthermore, the height of the truncated cone section is 5-7 cm. The height of the cylindrical section is 12-20 cm. The truncated cone section is smaller than the cylindrical section, which makes the entire tower spring have a more stable structure and a certain tactile feel. The overall height of the tower spring is 17-26 cm.

[0012] Furthermore, the width of the end of the truncated cone segment is 1-2 cm, and the width of the cylindrical segment is 3-5 cm.

[0013] A cushion core is formed by arranging a plurality of spring strings in parallel, wherein the spring strings are the above-mentioned partitioned pocket spring strings.

[0014] A mattress comprises an upper layer, a comfort layer, a support layer, a surrounding edge and a lower layer arranged in sequence from top to bottom, wherein the upper layer, the surrounding edge and the lower layer surround and wrap the comfort layer and the support layer, and the support layer is formed by arranging a plurality of spring strings in parallel, wherein the spring strings are the above-mentioned partitioned pocket spring strings.

[0015] The beneficial effects of the present invention are as follows: the present application is a partitioned pocket spring string, a cushion core and a mattress, wherein a connecting portion is provided to connect adjacent positioning tubes to form a reliable connection and a constraint to prevent the pocket spring string from producing a large displacement and deformation; force can be applied along the Y-shaped hot-melt connection seam to separate adjacent positioning tubes, making it convenient to set the number of positioning tubes according to needs, and the operation is simple and convenient.

DETAILED DESCRIPTION

[0027] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0028] Example 1

[0029] A partitioned pocket spring string, such as Figure 1 、 Figure 3 、 Figure 4 As shown, it includes multiple positioning cylinders 1 arranged side by side, each positioning cylinder 1 is provided with a tower spring 2, and a connecting part 3 is provided between adjacent positioning cylinders 1. A hot melt connection seam 4 is formed by hot melt connection on the connecting part 3, and the hot melt connection seam 4 is Y-shaped.

[0030] A connecting portion is provided to connect adjacent positioning tubes to form a reliable connection and a constraint to prevent the bagged spring string from causing large displacement and deformation; force can be applied along the Y-shaped hot-melt connection seam to separate adjacent positioning tubes, making it convenient to set the number of positioning tubes according to needs, and the operation is simple and convenient.

[0031] like Figure 3 and Figure 4 As shown, the connecting portion 3 is provided with an opening 5. In this embodiment, the opening 5 is a U-shaped opening located above the heat-melt connection seam 4. The zoned pocket spring string comprises alternating hard zones A and moderate zones B. The openings 5 ​​in the moderate zones B have a depth N1 of 0.5-1 cm, while the hard zones A are devoid of openings 5. The absence of openings 5 ​​in the hard zones A enhances correlation and supports strength, while the shallower openings 5 ​​in the moderate zones B reduce correlation and support strength. The alternating hard zones A and moderate zones B can meet diverse usage requirements.

[0032] like Figure 7 and Figure 8 As shown, the tower spring 2 is a spiral spring body, which includes a truncated cone section 21 and a cylindrical section 22 arranged from top to bottom, and the truncated cone section 21 is integrally connected to the cylindrical section 22.

[0033] The height H1 of the truncated cone section 21 is 5-7 cm. The height H2 of the cylindrical section 22 is 12-20 cm. The height of the truncated cone section 21 is smaller than that of the cylindrical section 22, which makes the entire tower spring 2 have a relatively stable structure and also has a certain tactile feel. The overall height H of the tower spring 2 is 17-26 cm. If the spring height is too high, it will take up more installation space and will be more likely to deflect or bend when subjected to lateral force or torque, affecting the stability and precision of the mattress. If the spring height is too low, it will limit its compression or extension stroke and cannot provide sufficient load-bearing capacity, resulting in deformation or even failure when bearing heavy loads. Springs with insufficient height may cause stress concentration at the ends or connections, making these areas more susceptible to fatigue fracture.

[0034] The width D1 of the end of the truncated conical section 21 is 1-2 cm, and the width D2 of the cylindrical section 22 is 3-5 cm. A spring that is too wide can make installation difficult or impossible; a spring that is too wide can increase stiffness, making it too hard when used as a mattress, affecting comfort; a spring that is too wide requires more material and more complex manufacturing, leading to increased costs. A spring that is too narrow can weaken its load-bearing capacity, making it prone to deformation or even breakage under heavy loads; a spring that is too narrow can be more prone to lateral deflection or twisting when subjected to force, failing to provide sufficient contact area and stability.

[0035] Example 2

[0036] like Figure 2 and Figure 5 As shown, this embodiment differs from Example 1 in that the zoned pocket spring string further includes a soft zone C located between the moderate zone B and the hard zone A. The opening 5 in the soft zone C has an opening depth N2 of 1-2 cm. The different soft and hard zones meet different usage requirements, and the pocket springs in different zones are connected and constrained to each other, effectively preventing significant displacement and deformation of the pocket spring string.

[0037] Example 3

[0038] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the depth of the opening 5 is set differently. This can provide differentiated support strength, which is not only beautiful but also meets different usage needs, especially adapting to the curves of the human body and providing a more comfortable sleeping experience. Figure 6 (a) is a schematic diagram of the depth distribution structure of the opening 5; Figure 6 (b) is a schematic diagram of the side structure of this embodiment, from which it can be seen that the depth of the opening 5 is specifically distributed in a wave shape.

[0039] Example 4

[0040] like Figure 9 As shown, a cushion core, the cushion core 8 uses multiple spring strings arranged side by side along the width direction, and the spring strings are the partitioned pocket spring strings of Example 2.

[0041] Example 5

[0042] like Figure 10 As shown, a mattress includes an upper layer 6, a comfort layer 7, a support layer 10, a surrounding edge 9 and a lower layer arranged in sequence from top to bottom. The upper layer 6, the surrounding edge 9 and the lower layer surround and wrap the comfort layer 7 and the support layer 10. The support layer 10 uses a plurality of spring strings arranged side by side, and the spring strings are the partitioned pocket spring strings of Example 2.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
