Description

[Technical field]

[0001] This invention relates to a futon or mattress whose size and shape can be freely changed. Whether for adults or children, and whether it is single or double size, the size of the futon or mattress (hereinafter referred to as "futon") can be changed and customized. [Background technology]

[0002] There are times in life when our living environment changes dramatically. For example, this is the time when we get married, have children, and they grow up. During this time, we change our clothes and bedding more. When a couple gets married, they move to a double size bed, when a child is born they start co-sleeping, and as the child grows the futon becomes too small, and so we have to change the futon every time. Also, as lifestyles become more diverse, there is an increasing demand for futons that can be used as cushions or pillows. This is why there is a growing demand for futons that are multifunctional.

[0003] In addition, futons used by infants and small children are small enough that they can sometimes be washed in a home washing machine, but single-size futons for adults are about 100mm thick and cannot fit into the washing tub of a standard home washing machine, making them difficult to wash. As a result, people often wash their futons at large laundries in town or hire a laundry service. This is time-consuming and expensive, so futons can go unwashed for long periods of time and become unsanitary.

[0004] In order to provide the above-mentioned multifunctionality and to enable washing at home, the futon needs to be able to be divided into pieces of suitable size.

[0005] Therefore, a nursing comforter that can be divided into three longitudinally and a mat-like bedding that can be divided into a plurality of component pieces and can be washed have been disclosed.

[0006] Patent document 1 discloses a comforter for nursing care, which is divided vertically into three parts, consisting of a central comforter and a left comforter and a right comforter on either side of it, and which is integrated by being engaged with the right end of the left comforter and the left end of the right comforter by fastening devices provided on the left and right ends of the central comforter.

[0007] Patent Document 2 discloses a prior art in which a mat-like bedding main body can be separated into a plurality of constituent pieces, and can be washed while still in the bag in which it is stored when used as bedding. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2012-5726 A [Patent Document 2] JP 2002-112853 A Summary of the Invention [Problem to be solved by the invention]

[0009] In Patent Document 1, the futons are joined together by inserting the belt through a belt loop and engaging with a fastening device, so the overlapping areas become stiff and uncomfortable.

[0010] Patent Document 2 discloses a mat-like bedding, in which the upper and lower components are made by intertwining polyester fibers and pressing them strongly to form a hard cotton-like material, and the middle component is made of foamed plastic such as ester-based urethane foam. Therefore, the components are joined by combining the recesses and protrusions provided on each component. Therefore, this joining form is not suitable for providing multi-functionality. In addition, when washing, the upper and lower components need to be separated, which is troublesome, as it takes time and effort to reassemble them after washing.

[0011] The present invention has been made in consideration of the above problems, and aims to provide a separate futon that can be divided to change the size, has multifunctionality, and has a simple structure for the joints that maintains the futon's softness and comfort.Furthermore, it aims to provide a separate futon that can be easily washed in a home washing machine. [Means for solving the problem]

[0012] In order to solve the above problems, the separate futon of the present invention is characterized in that the separable futon is composed of at least one first futon member and at least one second futon member, at least one side of the first futon member has a concave adhesive portion and at least one side of the second futon member has a convex adhesive portion, and a hook-and-loop fastener is arranged on one or both of the adhesive portions so that the concave adhesive portion and the convex adhesive portion can be attached and detached freely.

[0013] In addition, the separate futon of the present invention is characterized in that the extended portions on both sides of the concave adhesive portion are filled with contents.

[0014] In addition, the separate futon of the present invention is characterized in that the tensile shear strength in the width direction of the hook-and-loop fastener when adhered is greater than the peel strength.

[0015] In addition, the separate futon of the present invention is characterized in that the hook-and-loop fastener is flexible and thin.

[0016] In addition, the separate futon of the present invention is characterized in that a hook-and-loop fastener is arranged on the inner surface of the futon cover and the facing portion of the first futon member or the second futon member, or on either one of them, and the tensile shear strength in the width direction when adhered is greater than the peel strength. Effect of the Invention

[0017] The separate futon of the present invention has the advantage that by being separable, the overall size of the futon can be changed by adhering the futon parts together as the child grows.

[0018] In addition, the separate futon of the present invention can be separated so that it can be used as a cushion or pillow, thereby providing the effect of multi-functionality.

[0019] Furthermore, the separate futon of the present invention has the advantage that it can be separated and washed in a home washing machine. [Brief description of the drawings]

[Figure 12]This is a plan view showing a separate comforter d104 of Example 4. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The embodiment of the separate futon 10 according to the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing the appearance of the separate futon 10 of the present invention. Fig. 2 is a perspective view of the first futon member 12 of the separate futon 10 of the present invention. Fig. 3 is a perspective view of the second futon member 14 of the separate futon 10 of the present invention. The basic form of the separate futon 10 is composed of one first futon member 12 and one second futon member 14, with a concave adhesive part 124 on one side of the first futon member 12 and a convex adhesive part 144 on one side of the second futon member 14, and hook-and-loop fasteners are arranged on both adhesive parts, so that the concave adhesive part 124 and the convex adhesive part 144 can be attached and detached.

[0022] If the fabric of one of the adhesive portions is raised in a loop shape like a pile fabric, it is sufficient if the other adhesive portion is provided with a hook-shaped hook-and-loop fastener, but it is not necessary to provide hook-and-loop fasteners on both adhesive portions.

[0023] The concave adhesive portion 124 is formed by providing the extension portion 122 on both ends of the front and back of one side of the first comforter member 12, for example, and attaching a hook-and-loop fastener or a pile fabric to the concave inside by sticking or sewing it. If the extension portion 122 is provided on one side, air can easily enter from the side where the extension portion 122 is not provided, causing the heat-accumulated air inside the comforter to escape, or cold air from the outside to enter the inside of the comforter, so it is preferable to provide it on both sides. The convex adhesive portion 144 is formed by providing a gentle convex shape on, for example, one side of the second comforter member 14, and attaching a hook-and-loop fastener of a different type to the concave adhesive portion 124 by sticking or sewing it to the part corresponding to the concave adhesive portion 124. Alternatively, if a hook-shaped hook-and-loop fastener is attached to the concave adhesive portion 124, a loop-shaped hook-and-loop fastener is attached to the convex adhesive portion 144 by sticking or sewing it. When a hook-shaped hook-and-loop fastener is attached to the concave adhesive portion 124, if the convex adhesive portion 144 is made of pile fabric, a loop-shaped hook-and-loop fastener is not necessarily required. The reverse configuration is also possible.

[0024] FIG. 4 is a cross-sectional view showing an example of the joined state of the separate comforter 10 of the present invention. It is preferable to provide a space in the extension part 122 of the first comforter member 12 and fill it with contents. By filling the extension part 122 with contents, it is possible to prevent air from passing from the front to the back at the bonding part. FIG. 4 shows the case of a down comforter as an example. Down comforters usually have a partition to prevent the movement of feathers. In the figure, the partition part is shown with a broken line. It is preferable to provide a partition at the base of the extension part 122 as well to prevent the movement of feathers from the extension part 122 to the feather chamber.

[0025] The hook and loop fastener used in the separate futon 10 of the present invention is desired not to peel off against a force acting in the direction pulling each futon member, but to easily peel off against a force acting in the direction pulling the hook and loop fastener apart when the futon is released, so it is preferable that the tensile shear strength in the width direction when bonded is greater than the peel strength. This allows the hook and loop parts of the hook and loop fastener to be small, and they are formed to be flexible and thin, so that the softness of the part where the first futon member 12 and the second futon member 14 are bonded is maintained. If the hook and loop parts of the hook and loop fastener are made small, it is possible to provide many hook and loop parts in order to increase the tensile shear strength in the width direction when bonded. As a result, the separate futon 10 can be used with the same feeling as a normal single futon. In addition, when making the hook and loop parts of the hook and loop fastener small, it is preferable to increase the area of ​​the convex adhesive part 144 and the concave adhesive part 144, so that the tensile shear strength in the width direction when bonded tends to be greater than the peel strength.

[0026] Fig. 5 is a plan view showing an example of the joined state of the separate futon 10 of the present invention. It is a plan view of the joined state of the first futon member 12 shown in Fig. 2 and the second futon member 14 shown in Fig. 3. By making it possible to separate the futon in the middle when used as single or double bedding for adults, it can be easily washed in a standard-sized household washing machine, and there is no need to use a coin laundry with a large washing machine or send it to the dry cleaners.

[0027] FIG. 6 is a plan view showing a modified first comforter member 12 of the separate comforter 10 of the present invention. FIG. 7 is a plan view showing a modified second comforter member 14 of the separate comforter 10 of the present invention. By dividing the first comforter member 12 or the second comforter member 14 into smaller sizes than those shown in FIG. 5, it can be used for various purposes. As an example, by making the dimensions of the feather or cotton filling chamber of the first comforter member 12 and the second comforter member 14 in the plan view approximately 70 cm x 70 cm, it can be used as a cushion or a seat cushion. It can also be used as a comforter for infants. It can also be used as a pillow when folded. The 70 cm square is just an example, and it can also be 70 cm x 140 cm, and the dimensions are not particularly limited. Comforter members of different dimensions may also be combined.

[0028] If the first comforter member 12 and the second comforter member 14, each 70 cm square, are joined together, the length will be 140 cm, and the comforter can be used as a comforter for an infant. In order to join multiple first comforter members 12 and multiple second comforter members 14, variations in the arrangement of the concave adhesive portion 124 of the first comforter member 12 and the convex adhesive portion 144 of the second comforter member 14 are required. Figures 6 and 7 show several examples of variations. However, as long as the concave adhesive portion 124 or the convex adhesive portion 144 is provided, the shapes are not limited to these. Examples that utilize the variations of the comforter members shown in the figures are shown below. EXAMPLES

[0029] 8 is a plan view showing the separate futon a101 of Example 1. In the separate futon a101 of Example 1, the first futon member a1201 is placed on the left, the second futon member h1408 is placed in the center, and the first futon member b1202 is placed on the right and joined together. This results in a longitudinal length of 210 cm, which is a length that can be used by an adult.

[0030] 9 is a cross-sectional view showing a separate comforter a101 of Example 1. The comforter member constituting the separate comforter a101 may have both the concave adhesive portion 124 and the convex adhesive portion 144, but if the concave adhesive portion 124 is not joined to another comforter member, the extension portion 122 will droop and become unsightly and in the way. Therefore, it is preferable that the comforter member has either the concave adhesive portion 124 or the convex adhesive portion 144. EXAMPLES

[0031] Fig. 10 is a plan view showing the separate futon b102 of Example 2. In Example 2, two first futon members 12 and two second futon members 14 are used to create a shape close to a square. If the futon members are 70 cm square, the futon will be 140 cm x 140 cm, which is a size that allows two small children to sleep side by side. In the separate futon b102, the first futon member c1203 is placed at the top left, the second futon member c1403 rotated 180 degrees at the top right, the second futon member c1403 at the bottom left, and the first futon member c1203 rotated 180 degrees at the bottom right are arranged and joined. EXAMPLES

[0032] FIG. 11 is a plan view showing a separate futon c103 of Example 3. In Example 3, three first futon members 12 and three second futon members 14 are used to form a rectangle. In the separate futon a101 shown in FIG. 8, the short side is 70 cm, which is too short for an adult to use as a futon compared to the width of the body. Therefore, if two futon members are joined in the short side to form a futon member with a 70 cm square, the futon will be 140 cm x 210 cm, which is large enough for a single futon for adults. In the separate futon c103, the first futon member c1203 is placed at the top left, the second futon member f1406 rotated 180 degrees at the top center, the first futon member d1204 rotated 180 degrees at the top right, the second futon member c1403 at the bottom left, the first futon member e1205 rotated 180 degrees at the bottom center, and the second futon member d1404 at the bottom right are arranged and joined. EXAMPLES

[0033] Fig. 12 is a plan view showing the separate comforter d104 of Example 4. In Example 4, the three second comforter members 14 all used the second comforter member g1407. If the raised material used for the raised adhesive portion 144 is pile fabric or other material normally used for comforters and sheets, the exposed adhesive portion will not make the material feel uncomfortable. Sharing the components can reduce costs, which may be desirable. The same applies to the exposed adhesive portions in Fig. 10 or 11.

[0034] When using the duvet cover, the duvet cover may be provided with an extension 122, the extension 122 may be provided with a concave adhesive part 124, and the first duvet member 12 or a duvet member without a concave adhesive part may be inserted inside the duvet cover to form the first duvet member 12. A duvet member without a convex adhesive part may be provided inside a duvet cover without an extension 122, but if a second duvet member 14 with a convex adhesive part is provided inside a duvet cover without an extension 122, the convex adhesive part 144 provided on the second duvet member 14 can suppress the misalignment of the duvet cover and the second duvet member 14, which is preferable. The above shows a case where a duvet cover is provided for each duvet member, but the entire separate duvet may be inserted into one duvet cover and used. It is also possible to insert the second duvet member alone into the duvet cover and use it as a pillow, cushion, or duvet. When using a duvet cover, it is preferable to provide an adhesive part on the inner surface of the duvet cover using a hook-and-loop fastener or the like.

[0035] When the second comforter member 14 is inserted into the comforter cover and joined to the first comforter member 12, an adhesive portion must be provided at the same position as the second comforter member 14 on the surface of the comforter cover, and when the second comforter member 14 is inserted, it must be formed into a convex adhesive portion 144.

[0036] If it can be divided as described above, each futon component measuring, for example, 70 cm square, can be washed in a standard household washing machine. [Industrial Applicability]

[0037] The separate futon can be used as a futon, cushion, pillow, etc. for use by children and adults alike. [Explanation of symbols]
