DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a thin tatami mat which is used by being laid at an arbitrary position on a floor surface as required to give a feeling of tatami mats. .

[0002]

2. Description of the Related Art In many cases, the floor of a room is westernized to a wooden floor, a smooth floor made of synthetic resin or the like, a decorative floor, or the like. Even in such westernized houses, a comfortable Japanese-style space can be obtained by creating a space with tatami flooring. For such purposes, in recent years, thin tatami mats (thickness of about 1/3 to 1/5 that of ordinary tatami mats, about 20 mm in thickness) used for laying have been laid in the western space or the like. . Proposed examples of such thin tatami mats include JP-A-11-62191 and JP-A-9-195486. Because the use of thin tatami mats is easy to lay on a wooden floor or a synthetic resin floor, it can be moved to another room when cleaning or changing the layout of the room, or in the corner of the same room. Is often leaned against it. There is also an example of storing in a storage.

[0003]

The size of the conventional thin tatami mat is a normal tatami mat (about 1800 × 900 mm) or a half tatami mat (about 900 × 900 mm).
It is pointed out that it is too large to be stored in a storage or closet without being used, and that it is inconvenient to handle when cleaning by a housewife or the like. Therefore, we examined to solve these difficulties.

[0004]

As a result of studying the above-mentioned problems, as a result, the tatami mat has an elastic material between the tatami mat on the front surface and the back plate, and the back plate is divided in the longitudinal direction. , Which is provided with a middle folding hinge portion which is substantially perpendicular to the front surface side in the longitudinal direction, and is formed into a thin folding tatami mat. In order to integrate the front surface tatami surface, the back plate, the elastic material, and the like, a binder can be used, and the edges can be sewn and finished in the same manner as a normal tatami with an edge cloth. The location and the number of divisions are arbitrary, and are determined by the size of the thin tatami mat. It is preferable that the area is 3 divisions for 3 tatami mats, 2 divisions for 2 tatami mats, 1 tatami mat for half tatami mat, and about 2 tatami mats for a substantially half tatami mat.

[0005] Further, the tatami mat has a semi-tatami mat size having an elastic material between the tatami mat surface on the front surface and the back plate. A middle-bend hinge portion is provided at a substantially right angle in the longitudinal direction of the cover surface side, and a non-slip protuberance is provided on the back plate to form a thin center-bend tatami mat.

Further, the tatami mat is a semi-tatami mat-type thin tatami mat having an elastic material between the front tatami mat and the back plate, and the back plate is divided in the longitudinal direction so that the surface tatami mat covers the entire semi-tatami mat. A middle-bend hinge portion is provided at a substantially right angle in the longitudinal direction of the cover surface side, and a non-slip protuberance is provided on the back plate to form a thin center-bend tatami mat. The elastic material is preferably a synthetic resin foam or a nonwoven fabric. The presence of the elastic material imparts a suitable elasticity even when the thickness is small, and provides a preferable feeling. In addition, since the present invention is characterized by providing a hinge portion that enables folding, the dividing of the front side of the tatami mat and the provision of the hinge portion on the back plate side are substantially the same and are included in the present invention. .

The tatami mats referred to in the present invention are most commonly used rush woven fabrics, but tatami mats using rush-like weft or synthetic resin wefts or other rush-like wefts are used. Use is also included. In addition, the back plate makes the whole thin tatami hard, so that corner warpage does not occur due to aging,
Various boards can be used. For example, it is a wooden board, a wooden board, an integrated board, a metal board, or the like. Inexpensive ones are desirable. As the intermediate elastic material, a material having appropriate elasticity such as a synthetic resin foam such as polyurethane or polyethylene, a synthetic fiber or natural cotton, a single sheet or a laminated sheet of nonwoven fabric, and fiber waste can be used. A nonwoven fabric, particularly a cellulosic natural or semi-synthetic fiber (rayon or the like) is preferred because of its ease of handling during waste treatment and production.

Providing a bent hinge portion at a substantially right angle in the longitudinal direction of the front surface means forming a hinge substantially parallel to the weft of the rush fabric on the surface, and the hinge portion constitutes the rush fabric. If there is a problem with the strength, a reinforcing sheet or a reinforcing cloth for reinforcing the hinge may be attached to the hinge hinge.

The non-slip projection on the back plate is a point-like projection or a ridge of natural rubber or synthetic rubber having slip resistance, and may be formed directly on the back plate or formed on a non-woven fabric or woven fabric. The thing which stuck may be made to cover a back plate. These may be scattered on the entire surface of the back plate, or beveled at the edge, or formed partially at the center so that the anti-slip projection may directly contact the floor surface or other flooring material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. FIG. 1 is a partially cutaway perspective view of the folding center thin tatami of the present invention, and FIG.
FIG. 3 is a cross-sectional view at the time of folding, and FIG. 4 is a side view showing a folded state. As shown in these figures, a thin mat having a thickness of 17 mm in this example is a square having an elastic material 3 between a front tatami table 1 and a back plate 2 and having a thickness of 17 mm in this example. The back plate 2 is divided in the longitudinal direction, and the tatami mat 1 on the front surface covers substantially the entire surface, and the middle folding hinge portion 4 is substantially perpendicular to the longitudinal direction on the front surface side.
Is provided.

This example is of a half-tatami size (900 × 900 mm), and has a structure that can be folded in half and made compact 900 × 450 mm. Tatami Table 1 is a natural rush grass fabric. For the back plate 2, a particle board made by hardening wood powder or small pieces of wood with a binder was used. Although cedar boards and plywood obtained naturally can be used, it is preferable to use an integrated board to avoid warpage. The board of the back plate 2 is almost 10mm thick and almost
It is divided into two 900x450mm sizes. The elastic member 3 between the tatami table 1 and the back plate 2 is made of a polyurethane foam having a thickness of 5 mm, but may be made of rayon fiber, which is a material that can be easily disposed of. The rayon fiber non-woven fabric may have a thickness of about 5 mm, or a plurality of thin non-woven fabrics may be used. The elastic member 3 and the back plate 2 are bonded with a binder 5. As an example of the thickness of the tatami mat 1, the elastic member 3 and the back plate 2, in this example, the tatami mat 1 is 2 mm, the elastic member 3 is 5 mm, and the back plate 2 is 10 mm.

The function of the center folding hinge portion 4 is fulfilled by the tatami mat 1, the elastic member 3 and the edge cloths 6, 6, but in order to further reinforce them, a divided portion of the back plate 2, that is, both back portions, are provided. A reinforcing cloth 7 is bonded and integrated to the rear surface of the middle abutment portion (the middle hinge portion 4) of the face plates 2, 2. The tatami table 1, the elastic member 3 and the edge cloths 6, 6 are sewn together, and the back plates 2, 2 are bonded with a binder 5, and the reinforcing cloth 7 is bonded and integrated to complete the main part of the folded thin tatami of the present invention. , And a reinforcing cloth 7 is bonded and integrated to the back surface. The size of the reinforcing cloth 7 may be any size as long as it can be integrated over both back plates 2 and 2, and need not be particularly large.

The non-slip projections 8 provided on the back surface of the back plate 2
Rubber point projections with slip resistance.
Those formed at intervals of 10 mm are covered and adhered to the back of the back plate 2. Since slip resistance is imparted by the presence of the anti-slip projections 8, movement from the floor surface is eliminated.

[0014]

The thin folding tatami mat according to the present invention has the above-mentioned structure, so that when it is laid on the floor, the tatami is given a feeling of being laid, and any position on the floor can be adjusted as necessary. Can be laid down. When not in use, it can be compactly folded and stored in a storage or closet.
