Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to tatami mats, and particularly to tatami mats in which a tatami floor is formed using a plate-like body of rigid foamed plastic such as polystyrene foam.

[Conventional technology]

Due to the hot and humid climate, the architectural style of Japan's houses has changed significantly, and houses have become closed structures to improve the effectiveness of heating and cooling. Regarding tatami mats, hard foamed plastic materials such as polystyrene foam are used for part or all of the tatami floor.
Tatami mats are provided that are lightweight, have excellent heat insulation and moisture resistance, and are free from the risk of attracting dust mites.

[Problem that the invention attempts to solve]

However, tatami mats that use sheet materials such as polystyrene foam for the tatami floor lack resilience, and for tatami mats placed in rooms where many people come and go, the load may be repeated over many years. If the tatami gets stuck, it has the disadvantage that it has a low restoring force, causing partial dents and depressions, and easily losing its shape.As a result, there is a problem that the time for replacing the tatami is brought forward. .

The technical challenge of this invention was to eliminate the above-mentioned drawbacks of conventional tatami mats, and to provide tatami mats that do not curl and do not easily lose their shape even when subjected to repeated loads over many years. This was done to make it possible to extend the

[Means for solving problems]

This invention was developed as a technical means to achieve the above-mentioned problem by creating a tatami floor made of rigid foamed plastic plates, which has a thickness approximately equal to that of the rigid foamed plastic plates. A large number of thin reinforcing rods made of wood or bamboo having a long length are scattered in the plane direction and embedded perpendicularly to the surface of the plate-shaped body, and at least the upper or lower surface of the rigid foamed plastic plate. The gist is what was achieved by superimposing a thin plate on one side.

[Function] This invention is constructed as described above, and in the tatami of this invention, even when a load is applied to the tatami floor, many fibers are embedded in the rigid foam plastic plate forming the tatami floor. The thin reinforcing rods attached to the rigid foam plastic plate come into contact with a thin plate polymerized on at least one side of the upper or lower surface of the rigid foam plastic plate, distributing the load and supporting the rigid foam plastic plate. Prevents the body from denting,
It will not lose its shape even after many years of use. Furthermore, since the reinforcing rods embedded in the rigid foam plastic plate are made of wood or bamboo, the cutting blades may be damaged even when trimming the edges of the tatami floor to adjust its size. Never.

〔Example〕

Hereinafter, preferred embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a tatami mat showing an embodiment of this invention, and FIG. 2 is a perspective view of a rigid foamed plastic plate forming the tatami floor.

In the tatami according to this invention, the tatami floor 1 is formed using a plate-like body 2 made of rigid foamed plastic.
Polystyrene foam is commonly used as a rigid foamed plastic. The thickness of the plate-shaped body 2 may be determined as desired. The tatami floor 1 may be made entirely of hard foamed plastic, or may be partially made of hard foamed plastic.

A plurality of reinforcing thin rods 3, 3, .
... is embedded. That is, the reinforcing thin rod 3,
3, . . . have a length substantially equal to the thickness of the plate-like body 2, and are buried vertically so that their upper and lower ends are substantially flush with both the upper and lower surfaces of the plate-like body 2. The spacing between the reinforcement thin rods 3, 3, . . . may be determined as desired. The reinforcing thin rods 3, 3, . . . are made of wood or bamboo, and their thickness is made as thin as possible. Since the reinforcing thin rod 3 is made of wood or bamboo,
To prevent damage to a cutting blade even when trimming the edges of a tatami floor to the same size when adjusting the dimensions of the tatami floor. In addition, making the reinforcing thin rods 3 small in diameter minimizes the probability that the sewing needle will hit the reinforcing thin rods 3, 3, etc. during sewing work in the tatami floor manufacturing process, which will interfere with the work. This is to prevent this from occurring. It is preferable to make one end of the reinforcing thin rod 3 pointed, since this further reduces the probability that the sewing needle will hit the reinforcing thin rods 3, 3, . . . .

A thin plate 4 is superimposed on at least one of the upper and lower surfaces of the rigid foamed plastic plate 2. This thin plate 4 comes into contact with the thin reinforcing rods 3, 3, .
By dispersing and supporting the load, the plate-shaped body 2
can be prevented from denting.

The tatami floor 1 may be composed only of the thin plate 4 and the rigid foamed plastic plate 2, but it may also be composed of a layered structure including straw or the like. In the embodiment shown in FIG. 1, a thin plate 4 is superposed on the upper surface of a rigid foamed plastic plate 2, and
This shows a structure in which straw 6 is arranged between the tatami facing 5 and the thin plate 4, and a straw 7 is arranged below the plate-like body 2.
In addition, it goes without saying that a plurality of layers of straw or lint may be used, or moisture-proof paper may be provided.

[Effect of idea]

Since this invention is constructed and operates as explained above, even if the tatami of this invention is subjected to repeated loads over many years, it will not partially dent, slump, or lose its shape. There is no such problem, and the lifespan of tatami mats can be extended.
