Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami mat directly laid on a floor or the like.

[0002]

2. Description of the Related Art There is a so-called tatami tatami mat which is laid directly on a floor or the like in the western area to make a room with tatami mats. Since such floors are generally not partitioned by a higher sill, it is necessary to take care that the tatami mats laid thereon do not slip when a person rides on them. In particular, this non-slip is particularly important since the tatami mats may be partially laid on the floor. On the other hand, tatami mats must be along the floor and should not rattle when people walk. In addition, such tatami mats need to be lightweight because they are stored away after use.
In addition, it is inexpensive.

[0003]

For this reason, some laying mats have a reduced thickness and are provided with a structure for preventing slippage and preventing rattling. For example, Patent No. 2
Japanese Patent No. 961487 proposes a tatami floor in which a foam is laminated on a plywood, and a step is provided at an end portion of the tatami floor where the tatami mat surface wraps around the back surface to make the height of the back surface uniform. However, such a device is expensive and heavy because of the use of plywood. In addition, since the tatami edge is folded back, the processing of the thickness is also a problem, and the folded part of the tatami mat also overlaps with the tatami mat. The height of the back surface does not become uniform only by forming. Therefore, walking causes rattling and accompanying slippage. The present invention has solved such a problem, and has provided an inexpensive, lightweight, non-slip, tatami mat without rattling.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention covers a tatami mat of a rectangular EVA board with tatami mats attached at both ends in the width direction, with both tatami mats at both ends in the depth direction. ,
The tatami edge is folded back to the width direction end surface of the tatami floor and turned to the back surface to be fixed, and the surplus portion in the depth direction of the tatami mat surface is turned back to the depth direction end surface of the tatami floor and turned to the back surface to be fixed. The floor mats were provided.

In the present invention, first, an EVA board is used for a tatami floor. Therefore, it can be obtained at low cost. Here, EVA (ethylene vinyl acetate) is a copolymer of ethylene and vinyl acetate, and the higher the content of vinyl acetate, the more elasticity and flexibility. Increase. In this case, a foamed material is preferable because it is lightweight, but in this case, a material which is compressed to some extent and reinforced is suitable.

The tatami floor of the EVA board used in the present invention is required to have this elasticity and flexibility, so that even if the floor has irregularities (unevenness), it will have a backlash. Suppress slippage. In addition, since this is related to the thickness, a half-tatami mat (88 cm × 88 c
In m), one having a thickness of about 10 to 30 mm is used.
In addition, if such a property is provided, warping or twisting may occur during storage or the like, but it can be easily corrected by warping or twisting in the opposite direction.

[0007] According to the above, if there is no work done on the back of the tatami floor, the folded part of the tatami front will be raised to form a step, and the center of the back of the tatami floor will plow from the floor, and when walking, It may be dented. For this reason, in the above-described configuration, the present invention forms a step corresponding to the thickness at the end of the back surface of the tatami floor along which the wrapped portion of the tatami edge and the tatami mat surface are along, and a corner where the wrapped portions overlap each other. The height of the tatami mat and the height of the tatami mat and the surface of the tatami mat are provided so as to form a step corresponding to the thickness of the overlapping portion. Thereby, the whole back surface of a tatami mat follows a floor, and rattling and slippage can be suppressed.

Further, the tatami mat is obtained by sewing a portion of the tatami mat slightly indented from the end of the tatami mat with a thread, and then folding the tatami mat to the end. The end that wraps around may come apart and stand up. Therefore, if the tatami edge and the portion where the tatami mat and the tatami mat are fixed, including the border between the tatami mat and the tatami mat floor, are covered with thin vinyl tape,
This can be prevented from standing up, and at the same time, exposure of a fixing member such as a needle can be prevented. Further, at this time, if a vinyl tape having a rough surface is used, slip can be prevented.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a tatami mat according to the present invention is laid. The tatami mat itself is slightly larger than the tatami floor 1 in the depth direction in which tatami rims 2 are attached to both ends in the width direction of the tatami floor 1. Of the tatami mat 2 and the surplus part of the tatami mat 3 are turned to the back side to stop. In the present invention, as described above, the above-mentioned tatami floor 1 is composed of only EVA boards.

The attachment of the tatami edge 2 and the attachment of the tatami table 3 are performed as follows. FIG. 2 is a sectional view taken along the line AA in FIG. 1. The tatami edge 2 is aligned with the end of the band-shaped tatami edge 2 along the edge of the tatami table 3, and is sewn in the depth direction with a thread 4 and fastened. Have been. In this case, the size of the tatami table 3 in the width direction is the tatami floor 1
The folding of the tatami floor 1 by the tatami edge 2 in this direction is performed by folding the tatami edge 2 at the mating portion and turning it from the end face in the width direction to the back face, and the line near the end is fixed to a fixing member 5 such as a stapler. Is fixed to the tatami floor 1. In this case, the height is increased only in the portion where the tatami edge 2 is present. Therefore, if a step 6 equal to the thickness of the tatami edge 2 is formed in that portion, the height of the back surface becomes uniform.

FIG. 3 is a sectional view taken along the line BB of FIG. 1. When the tatami mat 3 is wrapped around the tatami mat 1 in the depth direction, the size of the tatami mat 3 in this direction is slightly larger than that of the tatami mat 1. Use the cut one. FIG. 6 is a perspective view showing this state. When the width direction of the tatami floor 1 is wrapped around the tatami edge 2, the depth direction protrudes from the depth direction of the tatami floor 1. Therefore, this extra portion is turned from the end surface in the depth direction of the tatami floor 1 to the back surface (at this time, the side portion in the width direction of the tatami edge 2 is folded inward) and fixed by the fixing member 5. Also in this case, since the portion where the tatami mat 3 is present becomes high, a step 7 equal to the thickness of the tatami mat 3 (thicker than the tatami edge 2) is formed in that portion so that the height of the back surface is made uniform. The above procedure may be reversed, and the width direction may be turned back after the depth direction is turned back.

FIG. 4 is a cross-sectional view taken along the line CC of FIG. 1 showing a corner portion of the tatami floor 1. In the corner portion, the overlapping portion 8 where the tatami edge 2 and the tatami table 3 overlap is formed. That is, immediately below the tatami floor 1, the folded tatami edge 2 and the tatami edge 2 extending below the tatami floor 1 overlap, and on the back of the tatami table 3, the double tatami attached to the surface is attached. Edge 2 will come. FIG. 7 is a rear view of the tatami floor 1, but even when this happens,
In order to make the height of the back surface of the tatami floor 1 uniform, it is necessary to form a step 9 in the overlapping portion 8 by adding the depth of the tatami edge 2 to the depth of the step 7 at the end in the depth direction. There is.

By the way, the thickness of the tatami table 3 is usually 1, 0
It is about 2.0 mm, and the tatami edge is about 0.2 to 0.8 mm. FIG. 7 is a rear view of the tatami floor 1. The depth of the step 6 in the width direction of the tatami floor 1 in which the tatami edge 2 is accommodated and the depth of the step 7 in the depth direction in which the tatami table 3 is accommodated are respectively adapted to this. Need to be On the other hand, the depth of the corner step 9 is at least four tatami edges 2 overlapped with each other.

The above tatami mats are laid on the floor and placed between tatami mats. At this time, since the back surfaces of the tatami mats have the same height, the tatami mats come into contact with the entire surface to prevent rattling and to suppress slippage. Is done. Also, when the tatami mats are no longer needed, they can be cleaned up, but even at this time, they are light and convenient to handle. FIG. 5 is a back view of the tatami mat covering the tatami floor 1 with the tatami table 3 as described above. The fixing member 5 is covered with the thin vinyl tape 10 including the tatami edge 2 and the boundary between the tatami table 3 and the tatami floor 1. Is preferred. This is to prevent the end of the tatami mat 2 from standing up and to prevent the fixing member 5 from being exposed.
By making the surface of 0 rough and hard to slip, an anti-slip effect can be expected.

[0015] The tatami mat having such a structure has a total thickness of 18 mm.
, The weight of a half-tatami mat is about 2.5 kg. Therefore, it can be easily carried by one person, and can be easily laid and cleared. Furthermore, since it is thin, it does not require a space (height) to store it in a stack.

[0016]

As described above, according to the present invention, since the EVA board is used for the tatami floor, it is light and inexpensive.
Also, even if a warp or twist occurs, it can be easily restored.
Furthermore, since the height of the back surface of the tatami mats is made uniform, no backlash occurs when walking or the like, and the accompanying sliding is suppressed.
