Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a new futon of stacking type.

[Prior art]

Futons are required to be light in use, have good breathability, good heat retention, and be bulky. However, the conventional techniques only improve the cotton, nonwoven fabric, etc. that make up the futon, and have not been able to achieve sufficient effects. Furthermore, when the conventional futon is folded for storage, the folded portion bulges out, making it bulky and requiring a large amount of storage space, which is problematic. Regarding futons with improved bulkiness, breathability, and heat retention, the present applicant previously proposed a stacked futon in which an air retention gap is provided between the upper part and the lower part in Japanese Utility Model Publication No. 18429/1983. is disclosed.
In addition, the full specification of Japanese Utility Model Application Publication No. 51-110813 discloses that a nonwoven fabric is integrally joined to one side of the fiber aggregate, and the remaining surface is covered with futon skin to form an upper part and a lower part, and these two parts are A technique has been shown to improve the bulkiness, heat retention, and breathability of futons by overlapping them on the nonwoven fabric side and fixing the peripheral edges. However, although this known technique provides bulkiness, when it is folded for storage, the folded portion swells and becomes bulky, resulting in a problem that requires a large amount of storage space.

In addition, Japanese Utility Model Publication No. 15638/1973 describes a technology for providing drape properties to the core material of futons, etc. by making linear cuts in a sheet-like foam material in a staggered manner, and then stretching and heat-setting the cuts until they become diamond-shaped. It is shown. However, when a futon made of this core material is folded for storage, the folded portion swells and becomes bulky, which causes the problem that it requires a large amount of storage space.

[Purpose of invention]

Therefore, an object of the present invention is to provide a futon that has excellent bulkiness, heat retention, and breathability, as well as improved storage performance.

[Structure of the idea]

The futon according to the present invention consists of overlapping a fiber aggregate such as cotton, wool, or non-woven fabric with a synthetic resin foam, covering the fiber aggregate side with a futon skin, and covering the synthetic resin foam side with a separator such as cloth or non-woven fabric. The upper part and the lower part are formed, and the two parts are stapled together using separate binding threads, and the two parts are overlapped on the separator side and fixed at the peripheral edge, and an air retaining space is provided between the two separators. is forming.

[Operation and effect of the invention] Therefore, air is retained in the gap between the upper and lower parts, and the separators in the upper and lower parts closely adhere to each other and capture the air, making it difficult for heat to escape and keeping the body warm. In addition to increasing the comfort of the futon, it is also highly breathable because it is divided into an upper and lower part, and the entire futon is bulky, providing a great cushioning effect. In addition, due to the compressibility of the synthetic resin foam used in the upper and lower parts, the folded portion collapses easily when folded, resulting in a significant reduction in bulk compared to conventional futons and greatly improved storage performance.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. The futon of this invention, whose entire part is indicated by A, has an upper part a.
and a lower part b. The upper part a and the lower part b are each made of cotton such as natural or synthetic fiber,
A fabric having a large number of holes h on the surface of the synthetic resin foam 2, which is made by laminating a fiber aggregate 1 such as a nonwoven fabric made of hair such as wool or feathers, or a synthetic resin, and a synthetic resin foam so-called foam rubber 2. That is, a separator 3 made of gauze or a thin sheet-like nonwoven fabric treated with heat and pressure and having a large number of holes h is layered, the surface of the fiber aggregate 1 is covered with a futon 4, and its peripheral portion is fixed to the separator 3 by sewing. 5 and configure. The upper part a and the lower part b constructed in this manner are stacked on top of each other on the side of the separator 3, and are united at their peripheral edges by the fixing means 6 to form the futon A. As for the fixing means 6, the upper part a and the lower part b can be easily separated so that they can be thoroughly dried in a futon, and a snap fastener or chuck fastener can be used so that only one part can be used depending on the temperature. Alternatively, fixing means such as stitching are preferred, but an integral one may also be used. In addition, 7 is a binding thread, and the upper part a
Parts a and b are separately closed by the lower part b and the lower part b. The synthetic resin foam has tensile strength,
For example, "M&C foam", a product of Toyo Goki Kagaku Kogyo Co., Ltd., has excellent elongation, compressibility, and recovery rate.
etc. are suitable.

Since the futon according to the present invention is constructed as described above, air is retained in the gap B between the upper part a and the lower part b (particularly the part bound with the binding thread 7), and the air is transferred to the upper and lower separators 3. , 3 are closely attached to each other and captured, making it difficult for heat to escape and improving heat retention.At the same time, since it is divided into the upper and lower parts, it has high breathability, and the entire futon A is bulky, which improves the cushioning effect. Large and comfortable to use. Furthermore, the separator 3 prevents the synthetic resin foam 2 from being damaged by the binding thread 7, and can reliably form an air-holding gap B in the portion bound by the binding thread 7.
Furthermore, since the separators 3, 3 are soft, the upper and lower parts fit well, and the upper and lower parts do not feel uncomfortable and can be constructed as if they were one futon. The gap B between the upper part a and the lower part B functions as an air-retaining gap, and warm air moves through this gap B along with body movements such as turning over, and does not press the capillaries, so blood can flow. Smooth circulation and comfortable elasticity ensure deep sleep. Furthermore, due to the excellent compressibility of the synthetic resin foams 2 and 2, Futon A
When folded, the folded part collapses without force, thus preventing bulkiness and reducing the bulk compared to conventional futons (according to folding tests, fiber aggregates 1, 1 and synthetic resin foams 2, 2) When the thickness ratio is 2:3, the bulk can be reduced to about 2/3 of the conventional one.
As a result, storability can be greatly improved. In addition, as the fixing means 6 is a snap fastener, chuck fastener, stitching, etc., so that the upper and lower parts a and b can be separated, so the upper part a and the lower part b can be easily separated and thoroughly dried in a futon. It is also possible to use only one part depending on the temperature, increasing versatility.

〔summary〕

As explained above, according to the present invention, the upper part and the lower part, which are constructed by overlapping synthetic resin foam and fiber aggregate and covering them with a futon cover and a separator, are overlapped to allow air to flow between the separators of both parts. Since the holding gap is formed, bulkiness, heat retention, air permeability, and storability can be improved.
