Description

[Detailed description of the invention] Industrial applications The present invention relates to a composite material for bedding.

Conventional structure and its problems Traditionally, futons using composite cushioning materials generally have a two- or three-layer structure, with the surface that comes in contact with the body as the top layer, and the structure is essentially It's one side and I can only use it.

OBJECTS OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a composite cushioning material with two sides of different hardness, which is comfortable to sleep on and can be used on both sides.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a comfortable sleeping experience.
In addition, two surfaces with different hardness are provided on the top and bottom surfaces, and the top surface is made of sheet-like synthetic fiber that has a good hygroscopic feel and has a soft wave shape that has a light acupressure effect. The middle layer is a hard plate-like layer with continuous convex shapes, and the toe surface feels like a futon with good moisture absorption. The sorted synthetic fiber 1 held in the hand is composed of a sorted elastic material with wavy irregularities that has a flexible property that has a light acupressure effect, and is used as a soft layer...-as an upper layer according to your preference. Composite cushioning material that can be used on both sides with different hardness depending on the type:
This composite cushioning material has a flexible property 7-1. Shape or bag & natsuzo (synthetic fiber V trowel covering, yarn-like synthetic fiber, resin, or band-like adhesive tape, band, etc.) There are 17 members connected together.

Description of examples Embodiments of the present invention will now be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a first surface layer made of sorted synthetic fibers having flexible properties, such as synthetic cotton, and is in contact with the wavy surface of a soft layer 2, which will be described later. 2 is a soft layer made of an elastic synthetic resin foam material having resilience against compression, such as urethane foam, and its -L side is formed into wave-like irregularities 3, and the lower surface is flat and flexible. The flat plate-shaped surface of the lower surface is in contact with the continuous convex-shaped surface of the middle layer 4, which will be described later. The soil surface has a continuous convex shape 6 having a large number of small protrusions 5, and the bottom surface has a flat plate shape with a large number of small protrusions 7. 8 is a flexible soil. The second surface layer is made of a synthetic wax material having a tooth-shaped property or an elastic resin foam material having resilience against compression, such as synthetic cotton or urethane foam. The surface in contact with the middle layer 4 is formed into a flat plate shape, and is in contact with the surface of the middle layer 4 on which a large number of small protrusions γ are provided, and the other surface is provided with small protrusions 9. 10 has a flexible property. The composite cushioning material is integrated with a cover made of synthetic fibers in the form of a sheet or bag 71 to facilitate insertion when inserting the composite cushioning material into the bag.

In addition, each layer is integrated in a state where it is in contact with the surface of the cloth,
11. Covered with a cover 10 and coupled with a fastening member 11. However, as shown in Fig.
It has a loaf shape and is fixed with a tape or band as shown in Figure 3. Removed toothpick shown in Figures 4 and 5, cover 1
The composite cushion material prepared at the bottom is stored in a bag 12 that connects a plurality of composite cushion materials to form a foldable bedding.

In the above configuration, the first surface layer 1 has -upper layer and (~
When used, the effect of the convex shaped surface of the middle layer 4 and the soft layer 2 relieves the hard feeling on the body and provides a soft and gentle acupressure effect. - When used as the L layer, it is applied without passing through the soft layer 2, so a relatively hard acupressure effect can be obtained.

Effects of the Invention As is clear from the above explanation, the present invention has the advantage of positioning the planar surface of the soft layer above the convex surface of the middle layer, and placing the first surface on the wavy surface of the soft layer. and the second surface layer is placed on the planographic surface having the small protrusions of the hard layer, the tenth surface layer, the soft layer, the hard layer, the second surface layer.
Since the surface layers are integrally bonded, you can obtain acupressure effects with different sensations between the entire upper layer of the first surface layer and the upper layer of the second surface layer. Can be used on both sides as required. Since the composite material is covered with a cover, it has practical effects such as making it extremely easy to insert multiple shoe materials into a bag that integrates them.
