Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mattress that is formed into a cylindrical shape and can be rotated from front to back.

[Conventional technology]

Generally, a futon is rectangular in plan, and is often made of a bag-shaped futon with cotton or synthetic cotton stuffed inside.

However, in recent years, mattresses filled with wool and cotton, which are lightweight, warm, and have excellent resilience, have become popular. However, wool cotton is more expensive than cotton cotton or synthetic cotton, so it is not as thick as traditional mattresses, but rather thinly stuffed to about 5 cm thick.

For this reason, during a short period of time during use, the central part of the futon became locally dented within an area of about 30 cm in width, and both sides remained bulged, making it extremely uncomfortable to sleep on.

Another problem was that even when the mattress filled with wool cotton was dried outdoors and exposed to sunlight, the dents did not recover much, and the dents would become large again after use.

In addition, traditional cotton mattresses are thick, so
Even if you dry it in the sunlight, it takes a long time to fully dry the inside, and it is also heavy to turn it inside out.
Drying futons was hard work for housewives.

[Problem that the invention attempts to solve]

The present invention was developed in consideration of these points, and it is possible to prevent local dents in the center and maintain a uniform thickness for a long period of time. It is an object of the present invention to provide a futon that dries even the inside in a short time even when the futon is used and dried, and that allows easy drying of the futon.

[Means for solving problems]

The present invention will be described in detail below with reference to embodiments shown in the drawings.

Figures 1 and 2 show an embodiment of the present invention, in which the futon body 1 has a width of 1 m and a length of 2 m, for example.
It is formed into a cylindrical shape with a rectangular planar shape.
This futon body 1 has a outer futon side 2A formed in a cylindrical shape.
Then, fold the longitudinal edges of the cylindrical back futon side 2B stacked on the inside a few centimeters inward as shown in Figure 2, and sew so as to leave a band-shaped edge 3. Attach it to form a bag, and line the inside with 4 pieces of wool cotton.
The edge 3 on the other side is similarly sewn into a band shape.

Furthermore, this cylindrical futon body 1 is divided into six equal intervals in the circumferential direction and sewn at six places along the longitudinal direction to form six seams 5a, 5b...5f, and then the futon body 1 is sewn into six equal intervals along the longitudinal direction. Sew in 2 places along the circumferential direction at intervals divided into thirds along the longitudinal direction of 1.
Book seams 6a and 6b are provided to form the whole into a quilted shape.

Also, six seams 5a, 5b along the longitudinal direction
... Each of the six parts 7a, 7b surrounded by 5f...
...band-shaped edges 3, 3 at both ends along the longitudinal direction of 7f
A male snap 8a and a female snap 8b are attached to the inside of the holder 8a and 8b so as to fit together at positions facing each other approximately at the center thereof. For example, part 7 of number 1
a has a male snap 8a and a female snap 8b,
A male snap 8a is arranged in the second part 7b, a pair of male snaps 8a and a pair of female snaps 8b are arranged in parallel in the third, fourth and fifth parts 7c, 7d and 7e, and further in the sixth part 7f. , one female snap 8b is attached.

[Effect]

Next, a method of using the mattress having the above structure will be explained.

First, the male and female snaps 8a and 8b attached to the inner sides of the longitudinal edges 3, 3 of the cylindrical futon body 1 are fitted together to close the edges 3, 3 on both end sides.

If you lie on the three parts 7a, 7b, 7c surrounded by the longitudinal seams 5a, 5b...5f on top and the other parts 7d, 7e, 7f on the bottom, it will be stuffed. Since the wool 4 being covered is thin, the central portions 7b and 7e are locally depressed as shown in FIG.

When this state is reached, remove the male snap 8a and female snap 8b from both edges 3, 3 to form a cylinder as shown in Fig. 1, shift and rotate as shown by the arrow in Fig. 3, and the seam will be removed. The side edges that were bent at 5a and 5d have turned around and become flat as shown in Figure 4, and the seams 5c and 5f have come to the side edges and are bent here, rising to the center. Portions 7a and 7d are located there. By sequentially rotating and using the futon in this manner, the entire surface of the futon body 1 can be used uniformly, and discomfort caused by localized depressions can be eliminated.

Also, if you dry this futon in the sunlight,
By removing the male snap 8a and the female snap 8b and making them into a cylinder, as shown in Fig. 5, by passing a clothesline 9 inside and hanging it, the back side can be exposed to sunlight by simply rotating it, without having to turn it over as in the past. and is easy to work with. Furthermore, since the futon can be dried in a cylindrical shape, air can circulate inside the futon, allowing it to dry quickly and drying the futon in a short period of time. In addition, when using a futon dryer, conventionally only hot air was blown from the surface of the futon, but by inserting an air mat inside the futon, hot air can be dried from inside the futon in a short time, especially for sick people who are bedridden for a long time. Effective as a mattress for the elderly. Also, when folding the futon and storing it in a closet, seam 6a,
6b can be folded into three, making it easy to fold.

FIG. 6 shows a futon cover 10 for hanging over a mattress according to the present invention, which is similarly formed into a cylindrical shape and has fasteners 11 attached to both edges along the longitudinal direction. This futon cover 10 is one in which the fastener 11 is opened and the futon shown in FIG. 1 is placed inside, thereby preventing the futon from shifting during use. When drying in the sunlight, both fasteners 11 can be opened to form a cylindrical shape, so the mattress can be hung on the clothesline 9 and hung to dry as shown in FIG.

In the above embodiment, both edges 3 of the futon main body 1,
Although a male snap 8a and a female snap 8b are used as attachments for closing the 3, other attachment structures may be used, such as a structure in which an eyelet-shaped ring is attached and tied with a string or the like.

Further, in the above embodiment, the case of a mattress stuffed with wool cotton 4 has been described, but it can be similarly applied to a mattress stuffed with cotton cotton or synthetic cotton.

[Effect of idea]

As explained above, according to the futon according to the present invention, it is possible to prevent local dents in the center and maintain a uniform thickness for a long period of time. Even when drying using a container, the inside of the bed can be dried in a short time, making it easy to dry the futon, which has remarkable effects.
