Abstract

PURPOSE:To provide a lightweight tatami mat which is excellent in heat insulation and moisture resistance and keeps shape without yielding even if loads are repeatedly applied over a long period of time by interposing a cushioning member between a honeycomb construction member and tatami surface, and laminating them together. CONSTITUTION:A honeycomb construction member 16 is provided which is form of an even, flat plate having a number of through holes 22 spaced apart by a wall surface body 24 in the form of a thin plate made of hard material. A cushioning member 20 is interposed between the honeycomb construction member 16 and a tatami mat surface 10 and they are laminated with one another to provide a tatami padding 12. Therefore, a load applied to the tatami padding 12 is borne by the honeycomb construction member 16. In this case, because the wall surface 24 of the honeycomb construction member 16 is made of hard material and the direction in which the body 24 is shaped coincides with that in which load is applied to the tatami padding 12, the honeycomb construction member 16 keeps shape without yielding even if used for a long period of time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami mat, and more particularly to a novel structure of the tatami mat.

[0002]

2. Description of the Related Art A tatami mat is manufactured by using dry rice straw as a material. In recent years, a tatami mat is partially or entirely made of a rigid foam plastic material such as polystyrene foam. Floor-formed tatami mats are also commercially available. A tatami mat using a hard foam plastic material for the tatami mat has the advantages that it is lightweight, has excellent heat insulation and moisture resistance, and there is no risk of mites.

However, a tatami mat using a plate-like material such as polystyrene foam on the tatami mat floor lacks in resilience. Therefore, if the tatami mat is laid in a room where many people come and go, the load may be repeatedly applied for many years. However, it has a defect that it is partially dented and falls, and it is easy to lose its shape. Therefore, there is a problem that a tatami mat made of polystyrene foam or the like has a shorter lifespan than a conventional tatami mat made of dried rice straw.

Japanese Utility Model Publication No. 5-9385 discloses a tatami mat that solves the above problems in a tatami mat using a plate made of a rigid foam plastic such as polystyrene foam for the tatami mat.
A large number of reinforcing thin rods having a length substantially equal to the thickness of the plate-like body of the rigid foamed plastic, scattered in the plane direction and driven perpendicularly to the plate-like body surface, respectively, and It is disclosed that a tatami floor is formed by superimposing thin plates on at least one side of an upper surface or a lower surface. In such a tatami mat, a large number of reinforcing thin rods disperse and support the load applied to the tatami floor, preventing the dent of the rigid foam plastic plate-like body, and even if it is used for many years. Does not collapse.

The present invention does not rely on the structure disclosed in Japanese Utility Model Publication No. 5-9385, but is lightweight, has excellent heat insulation and moisture resistance, and is free from the risk of mites and the like.
Moreover, it is an object of the present invention to provide a tatami mat whose shape is maintained without being depressed even if the load is repeatedly applied for many years.

[0006]

According to the present invention, the entire shape is a flat plate having a constant thickness, and in the thickness direction thereof, there are a large number of through holes separated by thin plate wall surfaces made of a hard material. The gist is that the tatami floor is formed by polymerizing the honeycomb structure member and the cushioning member interposed between the honeycomb structure member and the tatami mat.

[0007]

In the tatami having the tatami floor formed as described above, when a load is applied to the tatami floor, the load is supported by the honeycomb structure member which is the main body of the tatami floor. In this case, since the honeycomb structure member is formed so that the wall surface body is formed of a hard material and the forming direction of the wall surface body and the thickness direction of the tatami, that is, the load load direction are aligned, the load on the tatami floor is increased. The honeycomb structure member is not dented even if it is damaged, and its shape is maintained even if it is used for many years. In addition, since the main body of the tatami mat is a honeycomb structure member having a large number of through holes in the thickness direction, the tatami mat becomes light in weight, and an air layer is formed in the tatami mat part. It has good heat insulation and does not absorb moisture like straw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a tatami mat showing an embodiment of the present invention, and FIG. 2 is a partially enlarged perspective view of a honeycomb structure member forming the tatami floor.

This tatami mat is formed by arranging a tatami mat 10, a tatami mat 12 and a shin 14 in order from the top and polymerizing them. The tatami floor 12 is formed by superimposing a thin plate 18 on the upper surface of the honeycomb structure member 16 which is the main body, and superimposing a cushioning member 20 on the upper surface of the thin plate 18, and the upper surface of the cushioning member 20 on the tatami table 10. Are configured to cover.

Honeycomb structure member 16 that mainly forms the tatami floor 12
Is formed into a flat plate shape with a constant thickness, and a large number of through holes 22 are formed in the thickness direction of the thin plate wall body.
It is formed by being individually separated by 24. The honeycomb structure member 16 is made of a hard material such as a hard plastic material. Also, a cushioning member
20 is made of a hard foam plastic material such as straw or polystyrene foam, and is formed in a flat plate shape to give some cushioning to the surface of the tatami mat. The cushioning member 20 prevents the weight of the tatami from increasing when straw is used as the material for forming the cushion, and when the rigid foam plastic material is used, the cushioning member 20 has a dent as a whole tatami mat during long-term use. The honeycomb structure 16 is formed to be sufficiently thin as compared with the honeycomb structure 16 which is the main body of the tatami floor 12 so as not to stand out.

In the illustrated honeycomb structure member 16, the through-hole 22 has a hexagonal cross-sectional shape, but the cross-sectional shape may be quadrangular or the like. Further, in the case of forming the cushioning member 20 with straw or when arranging the body 14 on the lower surface side of the honeycomb structure member 16, they may be formed into a plurality of layers, and,
A moisture-proof paper may be inserted between each member having a layered structure.

In the tatami having the above structure, the load applied to the tatami mat is supported by the honeycomb structure member 16 which is the main body of the tatami floor 12. In this case, the wall surface body 24 of the honeycomb structure member 16 is formed of a hard plastic material and is arranged so that the wall surface and the load direction of the load match, so even if a load is applied to the tatami floor 12, Honeycomb structure member 16
Does not dent, and its shape is maintained. In addition, since the cushioning member 20 is arranged between the honeycomb structure member 16 and the tatami mat 10, the cushioning property is also provided to some extent, and there is not much discomfort when walking or sitting on the tatami mat. do not feel.

[0014]

EFFECT OF THE INVENTION Since the present invention is constructed and operates as described above, the present invention is light in weight and excellent in heat insulation and moisture resistance, and there is no fear that mites or the like will be generated.
Moreover, it has been possible to provide a tatami having a novel structure in which the shape is maintained without being depressed even if the load is repeatedly applied for many years.
