AI Technical Summary
Existing pocket spring mattresses are difficult to disassemble efficiently, especially since the springs are wrapped in fabric pockets and assembled into a mattress mesh. Disassembly efficiency is low, and ordinary consumers find it difficult to open the pockets. Furthermore, the glued fabric makes it difficult to remove the pockets.
Featuring a partitioned structure and easily removable stitching, the partitions are spaced apart along the bag's extension direction to avoid the stitching location. The stitching is located between the top and bottom of the spring string, using single or double stitching to ensure that the bag opening is not blocked by the bonded fabric or interlayer structure, and the stitching is easy to remove.
This allows for continuous opening of the bag opening, improving the convenience and efficiency of spring disassembly, reducing disassembly difficulty, and enhancing the ease and efficiency of spring recycling.

Abstract
Description
Technical Field
[0001] This application relates to the field of mattress manufacturing technology, and in particular to a detachable pocket spring string, bed net, and mattress. Background Technology
[0002] As a key component of spring mattresses, the production of pocket spring mattresses has achieved a high degree of automation. Currently, common pocket spring mattresses consist of multiple rows of pocket springs connected by adhesive or ultrasonic welding. The pocket springs are then encapsulated in fabric using ultrasonic welding or sewing.
[0003] The spring wires in discarded mattresses are recyclable and have some economic value. However, because the springs are wrapped in fabric bags and the spring strings are assembled into a mattress mesh, it is difficult to disassemble them. Disassembling the springs requires special tools or manual cutting and peeling, resulting in low efficiency. It is very difficult for ordinary consumers to disassemble the springs. In related technologies, the opening for removing the spring strings and mattress mesh is located at the end of the springs. If other padding layers or fabrics are attached to the mattress mesh surface, the opening can become stuck, making it impossible to disassemble. Utility Model Content
[0004] To solve at least one of the above-mentioned technical problems, this application provides a detachable pocket spring string, a bed net, and a mattress. By setting the partition structure to avoid the first seam line, the opening of the pocket is easily opened. The technical solution adopted is as follows.
[0005] The detachable pocket spring string provided in the first aspect of this application includes fabric, a partition structure, a first seam, and a plurality of springs. The fabric is folded to form a pocket, the pocket having an opening extending in a first direction. The plurality of springs are spaced apart in the pocket along the first direction, and the axes of the springs are arranged along a second direction. The partition structure is spaced apart on the pocket along the first direction, the partition structure extends along the second direction, and divides the pocket into a plurality of independent pocket chambers. The plurality of springs are separated in the pocket chambers to form a spring string, the spring string having a top end and a bottom end along the second direction. The first seam is arranged in the pocket along the first direction and closes the opening. The first seam is located on the side between the top end and the bottom end of the spring string, and the partition structure is arranged to avoid the first seam.
[0006] In some embodiments of this application, the first suture is made by single or double thread stitching, and the first suture is formed by an easy-to-remove stitching method.
[0007] In some embodiments of this application, the spring string has a front side and a rear side along a third direction, and the first stitch is disposed on the front side and / or the rear side of the spring string.
[0008] In some embodiments of this application, the first seam is close to the top end of the spring string, and the separating structure is disposed between the first seam and the bottom end of the spring string; or
[0009] The first seam is close to the bottom end of the spring string, and the separating structure is disposed between the first seam and the top end of the spring string.
[0010] In some embodiments of this application, the first seam is provided at the middle of the front and rear sides of the spring string, and the first seam divides the spring string into an upper segment and a lower segment along a second direction, and the dividing structure is respectively provided in the upper segment and the lower segment.
[0011] In some embodiments of this application, the partition structure includes a weld or a second seam.
[0012] Secondly, this application provides a bed net, including multiple rows of spring strings provided in the first aspect, the multiple rows of spring strings being arranged side by side along a third direction, adjacent spring strings being connected by adhesive or ultrasonic welding, and the connection position avoiding the partition structure.
[0013] In some embodiments of this application, the bed netting includes a top fabric and a bottom fabric, the top fabric being adhered to the top end of the spring string and the bottom fabric being adhered to the bottom end of the spring string.
[0014] Thirdly, this application provides a mattress, including an outer cover and a bed net provided in the second aspect, wherein the bed net is enclosed in the outer cover, and one or more sides of the outer cover are provided with a closure, which, when opened, corresponds to the end of the first seam of the bed net.
[0015] In some embodiments of this application, the mattress includes at least one interlayer structure that is enclosed within an outer cover and is disposed at the top and / or bottom of the mattress mesh.
[0016] The embodiments of this application have at least the following beneficial effects: by setting the first seam between the top and bottom ends of the spring string and the partition structure avoiding the first seam, it means that the opening of the bag avoids the top and bottom ends of the spring string. Therefore, when the first seam is disassembled, the interlayer structure or fabric adhered to the top or bottom ends of the spring string can be prevented from affecting the opening of the bag, and the partition structure can also be prevented from sticking to the opening of the bag. Therefore, after the first seam is disassembled, the opening of the bag can be opened continuously along the first direction, and the spring inside the bag can be exposed after the opening is opened, thereby realizing the disassembly of the spring and improving the convenience and efficiency of spring recycling.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0033] When making a bed net, multiple rows of springs are typically arranged side-by-side, with adjacent spring strings connected by adhesive or ultrasonic welding to form a bed net. Furthermore, a top fabric is glued to the top surface of each spring string, and a bottom fabric is glued to the bottom surface, which better secures the multiple rows of springs. Therefore, when recycling the bed net, the springs need to be removed from the spring strings. At this point, because the glued top and bottom fabrics will adhere the top and bottom ends of the multiple rows of springs together, disassembling from the top or bottom of the fabric bag will be quite difficult.
[0034] Based on this, this application proposes a detachable pocket spring string 100 (hereinafter referred to as spring string 100), which can reduce the difficulty of disassembling the spring string 100 and improve the ease and efficiency of spring 10 recovery. For the first aspect, please refer to... Figures 1 to 4 This application provides a detachable pocket spring string 100, including fabric, a partition structure 30, a first seam 40, and a plurality of springs 10. The fabric is folded to form a bag 20, the bag 20 having an opening 21 extending along a first direction x. The plurality of springs 10 are spaced apart in the bag 20 along the first direction x, and the axis of the springs 10 is arranged along a second direction z. The partition structure 30 is spaced apart on the bag 20 along the first direction x, and the partition structure 30 extends along the second direction z and divides the bag 20 into a plurality of independent pocket chambers. The plurality of springs 10 are separated in the pocket chambers to form a spring string 100. The spring string 100 has a top end 101 and a bottom end 102 along the second direction z. The first seam 40 is arranged in the bag 20 along the first direction x and closes the opening 21. The first seam 40 is located on the side between the top end 101 and the bottom end 102 of the spring string 100. The partition structure 30 is arranged to avoid the first seam 40.
[0035] By placing the first seam 40 between the top 101 and bottom 102 of the spring string 100, and by setting the partition structure 30 to avoid the first seam 40, the opening 21 of the bag 20 avoids the top 101 and bottom 102 of the spring string 100. Therefore, when disassembling the first seam 40, the interlayer structure 302 or the outer fabric adhered to the top 101 or bottom 102 of the spring string 100 can be prevented from affecting the opening 21 of the bag 20, and the partition structure 30 can also be prevented from sticking to the opening 21 of the bag 20. Therefore, after the first seam 40 is removed, the opening 21 of the bag 20 can be opened continuously along the first direction x. After the opening 21 is opened, the spring 10 inside the bag 20 can be exposed, thereby realizing the disassembly of the spring 10 and improving the convenience and efficiency of spring 10 recycling.
[0036] In some embodiments, the first seam 40 is formed using a single or double thread stitch, and the first seam 40 is formed using an easy-to-remove stitching method. The easy-to-remove stitching method allows the opening 21 to be sewn shut with one or two continuous threads, thus enabling continuous disassembly along the first direction x when removing the first seam 40, further improving operational convenience. For example, a common woven bag stitching method can be used, leaving a thread end at the end of the bag spring string 100. By cutting off the thread end, the entire first seam 40 can be quickly removed by tearing the end. The first seam 40 can be stitched using a single or double thread stitch. Figure 8 The first seam 40 is shown to be sewn using a single-thread stitch. Figure 9 The first suture 40 is shown to be double-stitched. After the thread ends are cut, the first suture 40 can be quickly and easily removed by simply pulling it in the direction of the arrow. Those skilled in the art can flexibly choose the stitching method for the first suture 40, as long as it achieves the purpose of quick suture removal.
[0037] In some embodiments, the partition structure includes a weld or a second seam. Using the partition structure 30 extending along the second direction z, the continuous space within the bag 20 can be divided into multiple independent small spaces, each containing a spring 10, thereby preventing the springs 10 from tangling together. The weld can be formed by ultrasonic welding or thermal welding (e.g.,...). Figure 1 , Figure 2 (As shown). The second seam can be formed by sewing.
[0038] In some embodiments, the spring string 100 has a front side and a rear side along a third direction y, such as Figures 1 to 3 As shown, the positive direction of the y-axis is the rear side, and the negative direction of the y-axis is the front side. The first seam 40 is located on the front and / or rear side of the spring string 100. That is, the bag 20 can have an opening 21 on either the front or the rear side. In this case, the first seam 40 is only located on the side of the bag 20 with the opening 21. After removing the first seam 40, the opening 21 on one side of the bag 20 opens, thereby exposing the internal spring 10. Alternatively, the bag 20 can have openings 21 on both the front and rear sides. In this configuration, the first seam 40 sews the openings 21 on both the front and rear sides of the bag 20. After removing the first seam 40, both openings 21 on both sides of the bag 20 open, and the two openings 21 can communicate with each other. Therefore, the bag 20 can be split into upper and lower parts along the second direction z, making it easy to remove the internal spring 10.
[0039] In some embodiments, please refer to Figure 1The first seam 40 is positioned close to the top end of the spring string 100, and the spring string 100 has a bisector along the second direction z located between the top end 101 and the bottom end 102 (e.g., Figure 1 As shown by the dotted line, the first seam 40 is positioned between the bisector of the line and the top end 101, and the dividing structure 30 is positioned between the first seam 40 and the bottom end 102 of the spring string 100. This arrangement means that no dividing structure 30 is provided between the first seam 40 and the top end 101 of the spring string 100; therefore, the space inside this part of the bag 20 is interconnected. On one hand, this arrangement prevents the dividing structure 30 from crossing the first seam 40 along the second direction z, ensuring that the first seam 40 can be continuously opened along the first direction x, allowing the opening 21 of the bag 20 to be continuously positioned along the first direction x, facilitating the removal of the springs 10. On the other hand, since the dividing structure 30 extends from the first seam 40 towards the bottom end 102 of the spring string 100, its length is greater than half the length of the springs 10. Therefore, the dividing structure 30 provides a good separation for the bag 20, preventing adjacent springs 10 from shifting or tangling.
[0040] Similarly, in another alternative embodiment, the first seam 40 is positioned close to the bottom end of the spring string 100, and the separating structure 30 is positioned between the first seam 40 and the top end 101 of the spring string 100. This arrangement also achieves the separating effect while allowing the separating structure 30 to avoid the first seam 40. The effect of this arrangement can be referred to in the previous embodiment, and will not be repeated here.
[0041] In some embodiments, please refer to Figures 2 to 4 The spring string 100 has a first seam 40 on both the front and rear sides, such as Figure 5 As shown, the positive direction of the y-axis is the rear side, and the negative direction of the y-axis is the front side. The first seam 40 divides the spring string 100 into an upper and lower section along the second direction z, and the partition structure 30 is respectively set in the upper and lower sections. With this arrangement, partition structures 30 are provided on both the upper and lower sides of the first seam 40 in the axial direction of the spring 10 (second direction z). That is, the partition structure 30 is divided into two discontinuous segments in the second direction z. Therefore, the partition structure 30 can be set with sufficient length in the second direction z to better achieve the separation effect of the internal space of the bag 20, further reduce the risk of displacement between adjacent springs 10, and can also meet the requirement of the partition structure 30 avoiding the first seam 40. When the first seam 40 is removed, the openings 21 on both sides of the bag 20 are opened, so it can be separated into upper and lower parts in the second direction z, thereby exposing the spring 10 and facilitating the recycling of the spring 10.
[0042] Secondly, please refer to Figure 5 and Figure 6 This application provides a bed net 200, including multiple rows of spring strings 100 provided in the first aspect. The multiple rows of spring strings 100 are arranged side by side along a third direction y. Adjacent spring strings 100 are connected by adhesive or ultrasonic welding, and the connection position avoids the partition structure 30. By using the parallel arrangement of multiple rows of spring strings 100, a bed net 200 can be formed. The connection position between the spring strings 100 avoids the first seam 40. In this way, when removing the first seam 40, the adhesive or welded position can be prevented from blocking the opening 21 of the fabric bag 20, ensuring that the opening 21 of the fabric bag 20 can be opened continuously, and improving the convenience of removing the springs 10.
[0043] In some embodiments, the bed net 200 includes a top fabric 201 and a bottom fabric 202. The top fabric 201 is bonded to the top end 101 of the spring string 100, and the bottom fabric 202 is bonded to the bottom end 102 of the spring string 100. The top fabric 201 and the bottom fabric 202 help to further fix and shape the multiple rows of spring strings 100, making the fixation between adjacent spring strings 100 more secure and preventing the spring strings 100 from dispersing.
[0044] Thirdly, please refer to Figure 7 This application also provides a mattress 300, including an outer cover 301 and a mattress net 200 as provided in the second aspect. The mattress net 200 is enclosed within the outer cover 301. One or more sides of the outer cover 301 have a seal, which, when opened, corresponds to the end of the first seam 40 of the mattress net 200. This allows the first seam 40 to be pulled open after opening the seal, enabling rapid disassembly of the spring string 100 and improving the ease of disassembly. The outer cover 301 can be a cover fabric or similar structure, which encloses the spring string 100, top fabric 201, bottom fabric 202, and other structures, thus isolating the top and sides of the mattress net 200 from the outside environment and preventing contamination of the interior of the mattress net 200.
[0045] In some embodiments, the mattress 300 includes at least one interlayer structure 302, which is wrapped inside the outer cover 201 and is disposed at the top or bottom of the mattress net 200. Alternatively, the mattress 300 may also have an interlayer structure 302 both between the top cover 201 and the outer cover 301, and between the bottom cover 202 and the outer cover 301. The interlayer structure 302 can be flexibly configured according to the function of the mattress 300. For example, the interlayer structure 302 can be a cooling layer, a cushioning layer, a support layer, a stain-resistant layer, etc., to meet the functional requirements of the mattress 300; no specific limitations are made here.
[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
