[0001] The present invention relates to a cushion body using a plurality of pocket coils. [Background technology]

[0002] BACKGROUND ART Conventionally, a plurality of pocket coils, each having a coil (spring) housed in a bag-shaped pocket, have been used as cushion bodies for mattresses and the like.

[0003] In this cushion body, bag-shaped pocket portions containing coils are arranged in a row on the left and right sides and connected via band-shaped connecting portions to form a row of pocket coils, and when used in a mattress or the like, multiple row of pocket coils are housed inside the bag-shaped outer body, arranged in parallel from front to back (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-259701 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the above-mentioned conventional cushion body, when it is housed in an outer body such as a mattress, it is necessary to house the multiple linear pocket coils in a parallel arrangement, which can cause the linear pocket coils to tip over during the housing process, and the work requires a great deal of time and effort. [Means for solving the problem]

[0006] Therefore, in the present invention according to claim 1, in a cushion body using a plurality of pocket coils, bag-shaped pocket portions containing coils are arranged in a row on the left and right and connected via connecting portions to form a row of pocket coils, and the row of pocket coils has a plurality of hollow pocket portions formed inside a flexible cover extending left and right, and the connecting portions are formed between adjacent pocket portions, Slit-shaped notches are formed above and below the connecting portion to make the vertical length of the connecting portion shorter than the vertical length of the pocket portion; Multiple pocket coil rows are arranged in parallel front and back, The connecting portions between adjacent pocket portions on the left and right sides of the multiple line-shaped pocket coils arranged in the front and back are in contact with each other, and the connecting portions between adjacent pocket portions on the left and right sides are alternately arranged in the front and back. I decided to join.

[0007] In addition, the present invention according to claim 2 is the invention according to claim 1, The vertical length of the connecting part is longer than the vertical length of the coil when it is fully compressed. I decided to do it.

[0008] In addition, in the present invention according to claim 3, Claim 1 In the present invention, The vertical length of the connecting part is shorter than the vertical length of the coil when it is fully compressed. I decided to do it. [Effects of the Invention]

[0009] The present invention provides the following effects.

[0010] In other words, in the present invention, in a cushion body using multiple pocket coils, bag-shaped pocket portions containing the coils are arranged in a row on the left and right and connected via connecting portions to form a row of pocket coils, and the multiple row of pocket coils are arranged in parallel from front to back and the multiple row of pocket coils lined up in the front and back are joined together by connecting portions, so that the row of pocket coils will not tip over when the cushion body is placed in an outer body such as a mattress, and the effort and time required for the placement work can be reduced.

[0011] In particular, if the multiple row-shaped pocket coils arranged in a row are joined together alternately front to back with connecting parts, a cushion body can be formed in which multiple row-shaped pocket coils are joined in a planar shape, thereby further reducing the effort and time required for the installation work.

[0012] Furthermore, if the connecting portions between adjacent pocket portions on the left and right sides of the multiple row-shaped pocket coils lined up front and back are brought into contact with each other, the distance between the coils can be shortened and multiple coils can be packed closer together (reducing the space where no coils are present), thereby improving the cushioning properties of the cushion body.

[Figure 2] Plan view (a) and front view (b) showing row-shaped pocket coils. [Figure 3] 10A to 10C are explanatory plan sectional views showing the process of forming the cushion body. [Figure 4] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] The specific configuration of the cushion body according to the present invention will be described below with reference to the drawings. Note that the following description will be given of the case where the cushion body according to the present invention is applied to a mattress.

[0015] As shown in Figure 1, mattress 1 accommodates a plurality of linear pocket coils 3 extending in a row in the left-right direction and arranged parallel to the front-to-back direction inside a rectangular hollow bag-shaped exterior body 2. The plurality of linear pocket coils 3 arranged in the front-to-back direction are connected to form a single planar cushion body 4. In the following explanation, the height direction of a person lying on mattress 1 will be referred to as the front-to-back direction, the width direction will be referred to as the left-to-right direction, the state seen from the foot side of a person lying on mattress 1 will be referred to as the front, and the foot side of a person lying on mattress 1 will be referred to as the front side (the head side will be the rear side).

[0016] As shown in FIG. 2, the linear pocket coil 3 contains a plurality of coils (springs) 6 arranged at equal intervals on the left and right inside a cover 5 extending in the left-right direction.

[0017] The cover 5 is made of two flexible front and rear sheets 7, 8 made of nonwoven fabric or the like, and the front and rear sheets 7, 8 are joined at their top, bottom, left, and right edges when stacked together, and are joined in a straight line from top to bottom at equal intervals in the left-right direction. The front and rear sheets 7, 8 can be joined by sewing, gluing, or welding with a solvent, but here the soluble nonwoven fabrics are thermocompression bonded together, eliminating the need for adhesives and ensuring long-term use without causing discomfort to the user.

[0018] In this way, the covers 5 are connected in a straight line, vertically and horizontally, with equal spacing between them, so that inside the cover 5 there are formed bag-shaped (hollow) pocket portions 9 that house the coils 6, and connecting portions 10 that connect adjacent pocket portions 9 on the left and right.

[0019] The coils 6 are housed one by one in each pocket 9 formed in the cover 5, with the deformation direction (flexure direction) facing up and down. Therefore, each pocket 9 has approximately the same space as the coil 6 when no force is acting on it. Note that the size of each pocket 9 may be changed to house coils 6 of different sizes, or each pocket 9 may house multiple coils 6 lined up vertically, or each pocket 9 may be divided into multiple sections vertically to house multiple coils 6.

[0020] As explained above, the linear pocket coil 3 is configured by arranging and connecting bag-shaped pocket portions 9, each containing a coil 6, in a row on the left and right via connecting portions 10. In the linear pocket coil 3, each pocket portion 9 and the coil 6 contained therein form one pocket coil.

[0021] 3 and 4, the cushion body 4 has a plurality of linear pocket coils 3 (3a, 3b, 3c, 3d) extending laterally and arranged in parallel from front to back with the outer peripheries of their pocket portions 9 in contact with each other, and the plurality of linear pocket coils 3 arranged in the front to back direction (first row of linear pocket coils 3a and second row of linear pocket coils 3b, second row of linear pocket coils 3b and third row of linear pocket coils 3c, third row of linear pocket coils 3c and fourth row of linear pocket coils 3d, ...) joined together by connecting portions 10. The linear pocket coils 3 may be joined together at their connecting portions 10 by sewing, adhesive, solvent welding, or the like, but here soluble nonwoven fabrics are thermocompression bonded together, and no adhesive is used, thereby preventing discomfort to the user and allowing for satisfactory use over a long period of time.

[0022] Moreover, the cushion body 4 has a plurality of linear pocket coils 3 arranged in the front-rear direction joined together by connecting portions 10 in a staggered manner.

[0023] For example, in the second row of linear pocket coils 3b, as shown in Figure 3, the connecting portion 10b-1 between the first pocket portion 9b-1 and the second pocket portion 9b-2 from the left of the second row of linear pocket coils 3b is joined to the connecting portion 10a-1 between the first pocket portion 9a-1 and the second pocket portion 9a-2 from the left of the first row of linear pocket coils 3a on the front side. The connecting portion 10b-2 between the second pocket portion 9b-2 and the third pocket portion 9b-3 from the left of the second row of linear pocket coils 3b is joined to the connecting portion 10c-2 between the second pocket portion 9c-2 and the third pocket portion 9c-3 from the left of the third row of linear pocket coils 3c on the rear side. The connecting portion 10b-3 between the third pocket portion 9b-3 and the fourth pocket portion 9b-4 from the left of the second row of linear pocket coils 3b is joined to the connecting portion 10a-3 between the third pocket portion 9a-3 and the fourth pocket portion 9a-4 from the left of the first row of linear pocket coils 3a on the front side. The connecting portion 10b-4 between the fourth pocket portion 9b-4 and the fifth pocket portion 9b-5 from the left of the second row of linear pocket coils 3b is joined to the connecting portion 10c-4 between the fourth pocket portion 9c-4 and the fifth pocket portion 9c-5 from the left of the third row of linear pocket coils 3c on the rear side. This joining is performed for all of the row of pocket coils 3.

[0024] In this way, the cushion body 4 alternately joins the connecting portions 10 arranged on the left and right sides of each row pocket coil 3 to the connecting portions 10 located on the front side (the connecting portions 10 of the row pocket coils 3 on the front side) and the connecting portions 10 located on the rear side (the connecting portions 10 of the row pocket coils 3 on the rear side), so that the connecting portions 10 of the multiple row pocket coils 3 arranged in the front and rear are joined in a staggered pattern, and the multiple row pocket coils 3 arranged in the front and rear are joined to each other by the connecting portions 10 in an alternating front-to-back manner.

[0025] Furthermore, the cushion body 4 joins the connecting portions 10 between adjacent pocket portions 9 on the left and right while bringing adjacent pocket portions 9 on the front and rear and left and right of the multiple linear pocket coils 3 arranged in the front and rear into contact with each other.

[0026] For example, regarding the first and second rows of linear pocket coils 3a and 3b arranged in front and behind, as shown in FIG. 4, the outer peripheries of the first pocket portion 9a-1 and the second pocket portion 9a-2 from the left, which are adjacent to each other on the left and right sides of the first row of linear pocket coils 3a, are in contact with each other, and the outer peripheries of the first pocket portion 9b-1 and the second pocket portion 9b-2 from the left, which are adjacent to each other on the left and right sides of the second row of linear pocket coils 3b, are in contact with each other, and furthermore, the first pocket portion 9a-1 from the left of the first row of linear pocket coils 3a and the first pocket portion 9a-2 from the left of the second row of linear pocket coils 3b, which are adjacent to each other on the front and rear sides, are in contact with each other. With the outer circumferences of the pocket portions 9b-1 in contact with each other and the outer circumferences of the second-from-the-left pocket portion 9a-2 of the first row of linear pocket coils 3a and the second-from-the-left pocket portion 9b-2 of the adjacent second row of linear pocket coils 3b in front-to-back contacting each other, a connecting portion 10a-1 between the first-from-the-left pocket portion 9a-1 and the second-from-the-left pocket portion 9a-2 of the adjacent first row of linear pocket coils 3a in the left-to-right direction is joined, and a connecting portion 10b-1 between the first-from-the-left pocket portion 9b-1 and the second-from-the-left pocket portion 9b-2 of the adjacent second row of linear pocket coils 3a in the left-to-right direction is joined. Regarding the second row of linear pocket coils 3b, as shown in FIG. 4, the second-from-the-left pocket portion 9b-2 of the second row of linear pocket coils 3b is in contact with the second-from-the-left pocket portion 9a-2 of the first row of linear pocket coils 3a adjacent to it on the front side, the second-from-the-left pocket portion 9c-2 of the third row of linear pocket coils 3c adjacent to it on the rear side, the first-from-the-left pocket portion 9b-1 of the second row of linear pocket coils 3b adjacent to it on the left side, and the third-from-the-left pocket portion 9b-3 of the second row of linear pocket coils 3b adjacent to it on the right side, and is joined to connecting portions 10b-1 and 10b-2 formed on the left and right sides of the second-from-the-left pocket portion 9b-2 of the second row of linear pocket coils 3b.

[0027] In this way, the cushion body 4 joins the connecting portions 10 of the multiple row-shaped pocket coils 3 lined up in the front and back with the outer peripheries of the adjacent pocket portions 9 in the front, back, and left and right directions closely packed (closely attached) together, thereby joining the connecting portions 10 between the adjacent pocket portions 9 in the left and right directions with the outer peripheries of the adjacent pocket portions 9 in the front, back, back, and left and right directions of the multiple row-shaped pocket coils 3 lined up in the front and back being in contact with each other.

[0028] The cushion body 4 may have the connecting portions 10 of the linear pocket coils 3 connected in a vertically straight line from the upper end to the lower end, or may have slit-shaped notches formed at the top and / or bottom to make the vertical length of the connecting portions 10 shorter than the vertical length of the pocket portions 9. In this case, the vertical length of the connecting portions 10 can be made longer or shorter than the vertical length of the coils 6 when the coils 6 are fully compressed.

[0029] As described above, the cushion body 4 is configured such that the bag-shaped pocket portions 9 containing the coils 6 are arranged in a row on the left and right and connected via connecting portions 10 to form the row pocket coils 3, and multiple row pocket coils 3 are arranged in parallel from front to back and multiple row pocket coils 3 lined up in the front to back are joined together by connecting portions 10.

[0030] Therefore, in the cushion body 4 of the above configuration, the linear pocket coils 3 will not tip over when the cushion body 4 is accommodated in an outer body 2 such as a mattress 1, thereby reducing the effort and time required for the accommodation work.

[0031] Furthermore, in the cushion body 4 having the above-described configuration, the row-shaped pocket coils 3 arranged in the front and rear are joined together, so that the multiple coils 6 of the multiple row-shaped pocket coils 3 arranged in the front and rear are linked together to bear the load, thereby improving cushioning properties such as sleeping comfort and sitting comfort.

[0032] The cushion body 4 is configured such that a plurality of linear pocket coils 3 arranged in the front-rear direction are joined together by connecting portions 10 in a staggered manner.

[0033] Therefore, with the cushion body 4 configured as described above, it is possible to form a cushion body 4 in which multiple row-shaped pocket coils 3 are joined together in a planar shape, thereby further reducing the labor and time required for the storage work and improving cushioning properties.

[0034] In addition, the cushion body 4 is configured such that adjacent pocket portions 9 on the front and rear and left and right sides of the multiple row-shaped pocket coils 3 arranged in the front and rear are in contact with each other, and the connecting portions 10 between adjacent pocket portions 9 on the left and right sides are joined together.

[0035] Therefore, in the cushion body 4 having the above configuration, the distance between the coils 6 can be shortened and multiple coils 9 can be densely packed (reducing the space where no coils 9 exist), thereby further improving the cushioning properties of the cushion body 4.
