Description

[Detailed description of the invention] This invention relates to the improvement of a mattress made of uneven sponge mats, and its purpose is to provide a comfortable mattress that does not have a floor attached and does not give a feeling of pressure when used. It is in.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
The underlay sponge mat a' has an uneven layer on its surface, and the overlying sponge mat a has an uneven layer on its surface and a flat back surface, and each sponge mat has an uneven layer on its surface. (T, D
, 1. Three-dimensional urethane bonds are formed by blending and mixing polyol (polyester or polyether) with water and a catalyst at a certain ratio, and the foaming of carbon dioxide gas generated by the reaction between isocyanate and water. It is a plastic foam formed by the parallel reactions of

In addition, an example of the physical properties of the underlay sponge mat a' with an uneven layer on the surface and the overlay sponge mat a with an uneven layer on the front surface and a flat back surface is 0.03% semi-specific gravity.
It has a hardness of 14 to 9 and a thickness of 40 mm, and its surface has unevenness of 25 Trr in the front, back, left and right directions on one surface!
The grooves are formed into deep troughs A of n, shallow trough openings of 10 mm in the diagonal direction, long pitches in the front, rear, left and right directions, and convexes and convexes with short pitches in the diagonal direction.

Also, the pitch is approximately 55 mm on the longer side and 35 Tr on the shorter side.
r! Set it to about 11.

In the figure, a breathable cloth is shown, and this cloth integrally covers the sponge mat and al.

The breathable cloth may be made of breathable fabric such as cotton cloth, but
When using stockinette fabric (made from raw threads such as synthetic fibers knitted into a 4-course diamond mesh of 7 inches and 16 courses) that expands and contracts from front to back and from side to side, the pressurized part stretches and contracts along the uneven layer on the surface of the sponge mat a. , the function and effect of the sponge mat a having the uneven layer on the surface are not impaired.

In addition, an underlay sponge mat a′ having an uneven layer on its surface,
Overlay sponge mat A, which has an uneven layer on the surface and a flat surface on the back side of the tile, has a pumping effect due to the vertical movement of the uneven part when used, and quickly releases sweat from the body to the outside. It disperses body pressure and does not crush the blood vessels in the pressure-receiving area, which prevents thin marks.Furthermore, because the pressure-receiving areas and non-pressure-receiving areas intersect and are scattered close to each other, even slight body movements can cause damage to the blood vessels. It also enables the movement of the pressurized area, has the effect of dispersing the load pressure due to body weight, and also has the function of preventing the continuation of the load pressure due to body weight.

The present invention consists of laminating an underlay sponge mat with an uneven layer on its surface, an overlay sponge mat with an uneven layer on the surface and a flat surface on the back of the tile, and covering these with breathable fabric. Therefore, when the user lies down, the curved part of the uneven layer of the overlay sponge mat, which has an uneven layer on the surface and a flat surface on the back side, supports the person, resulting in point contact, and the weight supported at that point is transferred to the lower layer. The load is dispersed and transmitted to the back side of the flat surface, and the back side is in contact with the convex surface of the underlay sponge mat, which has an uneven layer on the surface, so the load from your body weight is dispersed. The structure is such that each sponge mat is thin and lightweight, and because it is thin, it does not give the user a feeling of pressure, and because it is thin, it is easy to fold and store easily. There is a practical idea for a bed mattress.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, with FIG. 1 being a longitudinal sectional view and FIG.
The figure is an enlarged perspective view of a part of the sponge mat. In the figure, a is an underlay sponge mat with a textured layer on the front surface and a flat back surface, a' is an underlay sponge mat with a textured layer on the surface, and b is a breathable cloth.
