Abstract

PROBLEM TO BE SOLVED: To prevent the flattening of a filling formed like a flat plate by solid cotton and to maintain stable cushion property for a long time by fitting a columnlike elastic body which has the same height as a thickness of the filling and is harder than the filling into many through holes drilled on its plate face to integrate them. SOLUTION: A filling 1 employs solid cotton made of 100% polyester and is formed like a flat plate having a predetermined thickness and a rectangular shape, and the whole core material 1 is covered with an exterior material and is formed into a known mattress structure. Many circular through holes 4 are drilled on a plate face of the filling 1, and an elastic body 5 having the cushion property is fitted into each through hole 4 to integrate them. This elastic body 5 is formed using polyurethane which is a foaming synthetic resin harder than solid cotton, its height is set to be almost equal to a thickness of the filling 1, and the elastic body 5 is formed like a circular column having a diameter substantially equal to that of the through hole 4. Consequently, it is possible to prevent the fatigue of the core material 1 and maintain excellent cushion property for a long time because load is received by the elastic body 5.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core material useful for mattresses, mattresses and the like.

[0002]

2. Description of the Related Art Conventionally, core materials such as mattresses, mattresses, etc.
It is generally known to form a flat plate having a predetermined thickness from a foamable synthetic resin such as solid cotton or soft polyurethane.

[0003]

By the way, the core material made of solid cotton or foamable synthetic resin is excellent in water absorbency and moisture absorbency, but loses elasticity when used for a long period of time. And the sleeping comfort became worse.

Accordingly, the present invention has been made to solve the above-mentioned problems, and has as its object to provide an improved core material capable of preventing sag and maintaining a stable cushioning property for a long period of time. It is.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a core material formed of solid cotton in a flat plate shape, wherein the core material is provided with a large number of through holes on a plate surface thereof. In each through hole, a columnar elastic body having substantially the same height as the thickness of the core material and harder than the core material is fitted and integrated.

Preferably, the solid cotton is at least one selected from polyester, polyester and wool, or a mixture of polyester and cotton.

The elastic body is preferably at least one selected from foamable synthetic resin having a cushioning property, rubber, and a spring made of a resin. It is preferable to change according to the position.

According to the configuration of the present invention described above, it is possible to provide a core material such as a mattress or a mattress, in which sag is prevented by the elastic body and good sleeping comfort can be maintained for a long period of time.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a core material, FIG. 2 is a partially enlarged perspective view of the core material, and FIG. 3 is a cross-sectional view of a mattress using the core material of FIG. In FIG. 1, a core material 1 is formed into a rectangular flat plate with a predetermined thickness using 100% polyester solid cotton, and the whole is covered with an exterior material 2 as shown in FIG. A mattress 3 having a well-known structure is configured. As the solid cotton constituting the core material 1, for example, a mixture of polyester and wool or a mixture of polyester and cotton can be used.

Thus, in the present invention, the core 1
A large number of circular through-holes 4 are provided on the plate surface, and an elastic body 5 having a cushioning property is fitted into each of the through-holes 4 as shown in FIG.

The elastic body 5 is formed using polyurethane which is a foamable synthetic resin harder than solid cotton. The elastic body 5 has a height substantially equal to the thickness of the core material 1 and is formed in a columnar shape having a diameter substantially equal to that of the through hole 4. The elastic body 5 may be, for example, a spring made of rubber or resin.

According to the core member 1 having such a configuration,
When the user goes to bed, even if a load is applied to a portion corresponding to the shoulder, waist, or buttocks, the load is received by the elastic body 5 and the excessive sinking phenomenon is suppressed. Therefore, it is possible to prevent the core material 1 from sagging, and it is possible to maintain a comfortable cushioning property for a long time.

In the above-described embodiment, the through hole 4 is formed in a circular shape, and the elastic body 5 is exemplified as a columnar shape that matches the through hole 4. However, the present invention is not limited to this. The elastic body 5 may have a polygonal shape, and the elastic body 5 may be a pillar having a shape matching the through hole 4. In addition, by changing the hardness of the elastic body 5 at the user's body weight, the buttocks where a large load is applied, or the shoulder and the waist where the load is relatively small, the sleeping comfort can be further improved. Further, as shown in FIG. 4, the present invention can be similarly applied to a mattress 7 which can be freely folded by dividing the core material 1 into three in the longitudinal direction and covering the core material 1 with a three-foldable exterior body 6.

[0014]

As described above, the present invention relates to a core material formed of a solid cotton in a flat plate shape, a large number of through holes are provided in the plate surface of the core material, and each of the through holes has a core. It is approximately the same height as the thickness of the material, and is made by integrating a columnar elastic body that is harder than the core material, so that the core material can be effectively sagged by the elastic force of the elastic body. It is possible to provide a mattress, a mattress, and the like that can prevent the sleep and maintain good sleeping comfort for a long period of time.
