Technical Field

[0001] This application relates to the field of pillow core manufacturing, and more particularly to a pocket spring pillow core. Background Technology

[0002] In existing pocket spring pillow cores, the internal spring assembly mostly uses springs of a single specification, meaning that the springs throughout the entire pillow core area maintain uniformity in core parameters such as size and elasticity coefficient. To achieve differentiated firmness zones, it is common practice to layer elastic cushioning layers of different thicknesses or materials, such as memory foam, latex, or high-elastic fibers, to improve the comfort of pocket spring pillow cores. Utility Model Content

[0003] To address the aforementioned issues, this application provides a pocket spring pillow core that achieves different zones within the pillow core by setting pocket springs of varying heights.

[0004] This application provides a pocket spring pillow core, comprising:

[0005] The first bag of springs includes:

[0006] The first fabric, having a first chamber;

[0007] The first spring is located in the first chamber;

[0008] The second bag of springs includes:

[0009] The second fabric has a second chamber, which is annular;

[0010] The second spring is located in the second chamber;

[0011] Wherein, the height of the first pocket spring is greater than the height of the second pocket spring, the axial directions of the plurality of first pocket springs and the plurality of second pocket springs are parallel to each other, the first fabric is connected to the adjacent first fabric and / or the adjacent second fabric, and the second fabric is connected to the adjacent first fabric and / or the adjacent second fabric.

[0012] According to some embodiments of this application, the first spring and the second spring have different elastic forces due to different compression amounts.

[0013] According to some embodiments of this application, a plurality of first pocket springs and a plurality of second pocket springs form a multi-row spring string, the spring strings connecting adjacent spring strings.

[0014] According to some embodiments of this application, a plurality of first pocket springs and a plurality of second pocket springs constitute a spring string, the spring string being arranged in multiple rows in an S-shape.

[0015] According to some embodiments of this application, a plurality of second pocket springs are located in the middle region of the pocket spring pillow core.

[0016] According to some embodiments of this application, at least two of the first pocket springs constitute a first spring group;

[0017] At least two of the second pocket springs form a second spring group, which is spaced apart from the first spring group.

[0018] According to some embodiments of this application, the wire diameter of both the first spring and the second spring is ≤1.6mm.

[0019] According to some embodiments of this application, the second fabric wrapping the second spring is connected to the inside of the second spring by at least one weld point.

[0020] According to some embodiments of this application, the quantity ratio of the first pocket spring to the second pocket spring is 1:0.3 to 1:1.

[0021] According to some embodiments of this application, the first spring and the second spring have the same specifications.

[0022] According to some embodiments of this application, the pocket spring pillow core further includes a cover layer that covers the first pocket spring and the second pocket spring.

[0023] The first and second surface layers are made of at least one of the following materials: fabric, sponge, latex, and gel.

[0039] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a pocket spring pillow core (hereinafter referred to as pillow core) 100, which includes: a first pocket spring 1 and a second pocket spring 2, and the number of the first pocket spring 1 and the number of the second pocket spring 2 are both multiple.

[0041] The first bagged spring 1 includes a first fabric 11 and a first spring 12. The first fabric 11 forms a first chamber 13, and the first spring 12 is located in the first chamber 13. The first fabric 11 wraps around the outside of the first spring 12. In the first chamber 13, the first spring 12 is in a compressed state.

[0042] like Figure 3 As shown, the second pocket spring 2 includes a second fabric 21 and a second spring 22. The second fabric 21 forms a second chamber 23, which is annular. The second spring 22 is located in the first chamber 23, and the second fabric 21 wraps around the outer and inner sides of the second spring 22. In the second chamber 23, the second spring 22 is in a compressed state.

[0043] The height H1 of the first pocket spring 1 is greater than the height H2 of the second pocket spring 2. For example, the first fabric 11 and the second fabric 21 are made of the same material, and the compression of the second spring 22 is greater than the compression of the first spring 12, so that the height H1 of the first pocket spring 1 is greater than the height H2 of the second pocket spring 2.

[0044] The axes of the multiple first pocket springs 1 and the multiple second pocket springs 2 are parallel to each other. For example, the axes of the first pocket springs 1 and the second pocket springs 2 are both located in the vertical direction.

[0045] The pocket springs are connected to adjacent pocket springs, and the area surrounding the first pocket spring 1 can be the first pocket spring 1 and / or the second pocket spring 2. The first fabric 11 of the first pocket spring 1 is connected to the first fabric 11 of the adjacent first pocket spring 1, and / or to the second fabric 21 of the adjacent second pocket spring 2. The area surrounding the second pocket spring 2 can be the first pocket spring 1 and / or the second pocket spring 2. The second fabric 21 of the second pocket spring 2 is connected to the first fabric 11 of the adjacent first pocket spring 1, and / or to the second fabric 21 of the adjacent second pocket spring 2. The adjacent fabrics are interconnected along the radial direction of the pocket springs.

[0046] In the pocket spring pillow core 100, the height of the first pocket spring 1 is greater than the height of the second pocket spring 2. The positions of the first pocket spring 1 and the second pocket spring 2 are set according to requirements. By varying the height of different springs, the pillow core 100 can have different zones, for example, making the pillow core 100 more conform to the curve of the human head and neck, conforming to ergonomics. When making the finished pillow, a surface layer is wrapped around the outside of the pillow core 100, eliminating the need for other padding layers, thus simplifying the pillow manufacturing process.

[0047] In some embodiments, the first spring 12 and the second spring 22 have different elastic forces. For example, the first spring 12 and the second spring 22 have the same specifications, but the compression of the second spring 22 is greater than that of the first spring 12, resulting in the elastic force of the second spring 22 being greater than that of the first spring 12, and the area where the second pocket spring 2 is located has higher hardness.

[0048] like Figure 4As shown, in some embodiments, multiple connected pocket springs form a spring string 10. For example, multiple first pocket springs 1 and multiple second pocket springs 2 form a spring string 10. The number of first pocket springs 1 and second pocket springs 2 in different spring strings 10 can be different. The spring strings 10 connect adjacent spring strings 10, and multiple rows of spring strings 10 are connected sequentially to form a pocket spring pillow core 100. Optionally, adjacent spring strings 10 are connected by ultrasonic welding.

[0049] like Figure 5 As shown, optionally, a portion of the spring string 10 consists of a plurality of first pocket springs 1.

[0050] like Figure 6 As shown, in some embodiments, the pocket springs are arranged in sequence, and multiple first pocket springs 1 and multiple second pocket springs 2 form a continuous spring string 10. The spring string 10 is arranged in multiple rows in an S-shape, which facilitates the preparation of the pocket spring pillow core 100.

[0051] In some embodiments, a plurality of second pocket springs 2 are located in the middle region of the pocket spring pillow core 100. The arrangement of a plurality of second pocket springs 2 in the middle region of the pocket spring pillow core 100 makes the pillow core 100 more conform to the curves of the human head and neck, thus conforming to ergonomics.

[0052] like Figure 7 As shown, in some embodiments, at least two first pocket springs 1 are arranged sequentially to form a first spring group 20, and at least two second pocket springs 2 are arranged sequentially to form a second spring group 30, with multiple second spring groups 30 and multiple first spring groups 20 spaced apart.

[0053] In some embodiments, the wire diameter of the first spring 12 and the wire diameter of the second spring 22 are both ≤1.6mm. If the wire diameter of the first spring 12 and the second spring 22 is too large, it will increase the stiffness of the pocket spring pillow core 100.

[0054] like Figure 8 As shown, the second fabric 21 wrapping the second spring 22 is connected to the inner side of the second spring 22 by at least one weld point 24, which is formed by ultrasonic welding. The weld point 24 connects the top and bottom of the second fabric 21 to form an annular second chamber 23 inside the second fabric 21.

[0055] In some embodiments, the ratio of the number of the first pocket spring 1 to the number of the second pocket spring 2 in the pocket spring pillow core 100 is 1:0.3 to 1:1.

[0056] In some embodiments, the first spring 12 and the second spring 22 have the same specifications, which facilitates the preparation of the pocket spring pillow core 100.

[0057] Optionally, the first spring 12 and the second spring 22 are made of stainless steel or stainless iron. The first fabric 11 and the second fabric 21 are made of lightweight non-woven fabric or cotton fabric.

[0058] Optionally, the fabric of the pocket spring pillow core 100 is a continuous fabric. Part of the fabric, as the first fabric 11, forms a first chamber 13 for wrapping the first spring 12. Part of the fabric, as the second fabric, forms a second chamber 23 for wrapping the second spring 22.

[0059] like Figure 9 As shown, in some embodiments, the pocket spring pillow core 100 further includes a surface layer 3, which covers the first pocket spring 1 and the second pocket spring 2 to further improve the comfort of the pocket spring pillow core 100. Optionally, the surface layer 3 is made of at least one of fabric, sponge, latex, and gel.

[0060] like Figure 10 As shown, in some embodiments, the surface layer 3 includes a first surface layer 31 and a second surface layer 32. The first surface layer 31 is located above the second surface layer 32, and the first surface layer 31 and the second surface layer 32 are connected. The surface layer 3 covers the first pocket spring 1 and the second pocket spring 2. The outer surface shapes or hardness of the first surface layer 31 and the second surface layer 32 are different, and the outer surface shapes or hardness of the first surface layer 31 and the second surface layer 32 are set according to requirements.

[0061] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the technical solutions and core ideas of this application. Therefore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application.
