futon

Abstract

To provide a futon suitable as a mattress pad, which has a sufficient thickness and volume and can be easily folded into a compact shape, for example, in three. [Solution] A laminated futon is constructed by encasing a central core 1 in flat, bag-shaped side fabric 3, which becomes upper and lower layers 3A and 3B. Crease quilting 6 is formed and placed on at least one of the upper and lower layers 3A and 3B at the crease position when the futon is folded. When the futon is flat and rectangular, the crease quilting 6 is placed approximately 1 / 3 of the way along the longitudinal length from the longitudinal edge, and is configured in a wavy line shape. This allows creases to be easily formed by the crease quilting 6 when the futon is folded at the crease quilting 6 position, resulting in a compact triple-layered structure, for example, folded in three.

Description

[Technical Field]

[0001] This invention relates to a futon that is suitable as a mattress, which has a sufficient thickness and volume, yet can be easily folded into a compact shape, for example, in three. [Background technology]

[0002] Futon mattresses and comforters have traditionally been used as bedding for sleeping, and futon mattresses in particular need to be thick and voluminous to support the body while sleeping. However, it is not enough to just have thickness and volume; they also need to be easily foldable, as they can be folded and stored when not in use.

[0003] For this reason, conventionally, proposals have been made for a mattress such as that shown in Patent Document 1 and a washable soft solid cotton mattress such as that shown in Patent Document 2. The mattress of Patent Document 1 is made by enclosing a mattress core containing polyester solid cotton in an outer mattress bag sewn with quilt material. The solid cotton mattress of Patent Document 2 is made by enclosing soft solid cotton, which is a blend of polyester cotton and low-melting polyester binder cotton, and is heat-sealed, in the upper and lower side fabrics.

[0004] [Patent Document 1] Registered Utility Model No. 3032545 [Patent Document 2] Registered Utility Model No. 3114362 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the conventional mattress pad in Patent Document 1, which is separated into a mattress pad core and an outer mattress bag, it is possible to recycle the mattress pad core and wash only the outer mattress bag, but due to its bulkiness it is difficult to fold compactly for storage when not in use. Also, according to the solid cotton mattress pad in Patent Document 2, although the soft solid cotton pad is stored in the side fabric and quilted from the outside of the side fabric, which makes it possible to fold it in thirds, the thickness of the soft solid cotton pad is maintained at the fold, so it is voluminous and can spread out and collapse due to its resilience.

[0006] This invention was devised in consideration of the various circumstances that have existed in the past as described above, and aims to provide a futon that is thick enough and voluminous enough to be used as a mattress, thereby providing a comfortable sleeping experience, and that can be folded compactly into three, for example, when stored when not in use. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, this invention is characterized in that a futon has a laminated structure in which a central core material 1 is housed in flat, bag-shaped side fabric 3 which becomes an upper layer 3A and a lower layer 3B, and fold quilting 6 is arranged and formed on at least one of the upper layer 3A and the lower layer 3B at the fold position when folding. When the futon is flat and rectangular, the fold quilting 6 can be configured to be positioned at a position approximately 1 / 3 of the length along the longitudinal direction from the longitudinal edge. The fold quilting 6 can also be configured in a wavy line shape.

[0008] In the futon of this invention, which is configured as described above, the fold quilting 6 arranged and formed on the upper layer 3A or lower layer 3B of the side fabric 3 covering the central core material 1 becomes the fold when folding, and is folded together with the central core material 1, which has a predetermined thickness and volume. A crease quilting 6 located 1 / 3 of the way from the longitudinal edge along the longitudinal length allows the bag to be folded in three to form a compact triple configuration. The wavy crease quilting 6 maintains the stitching strength and also forms crease lines with a slightly wider wavy width, making it easier to form creases when folding. [Effects of the Invention]

[0009] Because this device is configured as described above, when it is configured as a mattress, for example, the creases are formed by the quilting 6 when it is folded, and it can be easily folded compactly even if it is thick and voluminous.

[0010] This is because in this invention, the fold quilting 6 is arranged and formed in either the upper layer 3A or the lower layer 3B of the bag-shaped side fabric 3 that contains the central core material 1 and forms a laminated structure, thereby forming folds when folding, making it easy to fold.

[0011] Furthermore, when the bag is configured in a rectangular shape, by forming the fold quilting 6 at a position 1 / 3 of the length from the longitudinal edge, it can be folded compactly into three, and the folding operation can be smoothly performed by holding one of the longitudinal edges, folding along the front and back, and then folding back.

[0012] When folding, the crease quilting 6 is formed in a wavy line shape, so that the creases are wavy, making it easy to fold and allowing the creases to be maintained for a long period of time.

[0013] The reference numerals in the sections of the means for solving the above problems and the effects of the invention are used to facilitate reference to the components shown in the drawings. The invention is not limited to the structure and shape shown by the descriptions and the reference numerals in the drawings. [Brief explanation of the drawings]

[0014] [Figure 1] 1A and 1B are partially cutaway perspective views showing one embodiment of the present invention, in which (A) is the front side and (B) is the back side. [Figure 2] These are also side views of the folding process into thirds, with (A) showing the beginning of folding, (B) showing the middle of folding, and (C) showing the end of folding. [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Below, one embodiment of this invention will be explained with reference to the drawings. The reference numeral 1 shown in the drawing is a central core material called solid cotton, which is formed to have a volume with a predetermined thickness using, for example, polyester cotton or other suitable material.

[0016] This central core material 1 is covered on the front, back and sides with a sheet-like cover material 2 called rolled cotton, and the central core material 1 covered with this cover material 2 is stored in a flat, bag-like side fabric 3 which forms the upper layer 3A and lower layer 3B, and the edges are sewn and fixed with a hem material 4, thereby forming a laminated futon.

[0017] That is, when it is housed in the side fabric 3, it has a three-layer laminated structure consisting of an upper layer 3A, a central core 1, and a lower layer 3B, and is configured as, for example, a mattress. When it is made into a mattress that has a rectangular shape in plan view, it is formed to have a length of, for example, about 200 to 210 cm and a width of, for example, about 100 cm. Of course, there is no particular limitation on these sizes.

[0018] The upper layer 3A of the side fabric 3 is provided with quilting 5, for example, in a grid pattern, so that the upper layer 3A itself is kept flat.

[0019] Additionally, the lower layer 3B of the side fabric 3 is formed with crease quilting 6, which serves as the crease along which the mattress itself is folded. For example, when folding the mattress into thirds, two crease quiltings 6 are formed at a position approximately one-third of the length from the edge along the length. The number of crease quiltings 6 is determined depending on the folding form when folding the mattress.

[0020] When folded in thirds, this fold quilting 6 is set at a position approximately 70 cm from the longitudinal edge if the length of the mattress itself is, for example, 210 cm, and at a position approximately 65 cm from the longitudinal edge if the length is, for example, 200 cm.

[0021] Furthermore, the fold quilting 6 is not limited to being formed on the lower layer 3B, but may also be formed on the upper layer 3A, or when there are multiple fold quiltings 6, they may be formed in different positions on both the upper layer 3A and the lower layer 3B. It is preferable that the fold quilting 6 is formed on the inner side of the upper layer 3A or lower layer 3B where the fold will be, but in any case, it may be formed on either the upper layer 3A or lower layer 3B at the position where the fold will be.

[0022] As shown in the figure, it is preferable that the fold quilting 6 is formed in a wavy line (wave) in order to maintain stitching strength. Although not shown in the figure, it is also possible to form it in a straight line, and as long as it is arranged along the fold, one fold quilting 6 may be formed in multiple rows in some cases.

[0023] Furthermore, both the quilting 5 and the fold quilting 6 are sewn only onto the side fabric 3 of the upper layer 3A and the lower layer 3B, and are not formed on the central core material 1, so the thickness and volume of the central core material 1 itself are not affected.

[0024] Next, an example of how to use this will be explained. As shown in Figure 2, when folding it into a Z shape when viewed from the side in three, fold it at one of the parallel quilted folds 6 (see Figure 2(A)), then turn it over and fold it at the other quilted fold 6 (see Figure 2(B)), and then fold it as is (see Figure 2(C)).
