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 tatami mat having an adjustable size.

[0002]

BACKGROUND OF THE INVENTION Traditionally, tatami mats are manufactured from the dimensions of the finished room and the cutting of the flooring accordingly. Therefore, in principle, it is custom-made one by one, and it is natural that the dimensions match.

[0003]

However, exactly 1 mm
Requirement of unit accuracy is almost impossible in the manufacture of tatami mats, and it is almost impossible to repair tatami mats if they are too small and have gaps. Therefore, conventionally, the tatami was made to be 1 to 2 mm larger and pushed in. Also,
Even if it was a little too large, it could be deformed in the case of a conventional straw bed, and could be adjusted to about 1 to 2 mm when hit with a mallet or the like.

[0004] However, with the recent plastic flooring, on-site deformation is almost impossible. In addition, thin tatami mats have been frequently used, but also from the problem of strength, rigid materials such as veneer are used for flooring. Such a thing is also difficult to deform.

[0005] In many cases, the last one tatami mat is not actually inserted, and the tatami mat is remade again. On the other hand, when the tatami mat is not inserted, the adjustment cannot be performed.

[0006]

The inventor of the present invention has completed the tatami mat of the present invention as a result of intensive studies. The point is that the deformable member is sandwiched.

A deformable member is one that can be relatively easily deformed on site, thereby changing the size of the entire tatami mat. This deformation also includes a deformation that does not return to its original state, such as plastic deformation, and a deformation that returns to its original state, such as elastic deformation. In the case of plastic deformation, it is easy to put a tatami mat in order to keep its shape when deformed. In addition, in the case of elastic deformation, it is difficult to insert the tatami mat because it is inserted while being deformed.

In the case of a plastically deformable member, it is necessary that the member be more easily deformed than the material of the floor material. For example, it is an insulation board or other wood fiber board which is soft. At the site, if two tatami mats are forcibly inserted together, they can be deformed or easily deformed with a mallet or the like. However, it must not be deformed by the tension when the tatami mat is stretched, so it is necessary to have an intermediate flexibility. If this is expressed numerically, the deformation strength is 100 to 4000 N
/ Cm ² (force at 25% deformation) is good.
Those having 600 N / cm ² are preferred. The size is
It suffices if it is smaller than the side surface of the flooring material, but it is desirable to arrange the upper ends so that there is no step on the front side of the tatami mat.

[0009] Even in the case of the elastically deformable member, it is necessary that the elastically deformable member is more easily deformable than the material of the floor material. For example, rubber, foamed plastic, and the like. This is also the same as above in that it must not be deformed by the tension when the tatami mat is stretched. Even if the elastic deformation member is hard, it deforms when a force is applied.
However, those having an elastic coefficient such that the volume is reduced to half by the above-mentioned force of 100 to 4000 N / cm ² are preferable.

The deformable member is sandwiched between at least one side of the floor material of the tatami mat and a tatami mat.
You may put in the side. It goes without saying that the more you put, the easier the adjustment will be. In addition, the effect varies according to shape of tatami itself, usually size and half tatami size,
Tatami with different numbers of sides may be mixed and laid in one room. Only the last tatami mat or the surrounding tatami mat may be made such an adjustable tatami mat.

[0011] In addition, as a place to put the tatami mat, if it is one side, the long side or the short side of the tatami mat may be used, and the side having no edge may be used. Further, the same applies to the case where the image is put on two sides, and the image may be put anywhere. Two opposite sides or two adjacent sides may be used.

The thickness of these members may be different between the case where they are provided only on one side and the case where they are provided on all four sides, and it is better. Usually, about 5 to 15 mm is good. When only two sides are provided, it is more efficient that the sides on which the deformable members are provided do not match when the tatami is laid. However, it is not difficult to insert the deformable member only into the tatami frame portion (a portion where the longitudinal direction of the rush is parallel to the side) and to lay the tatami mats adjacent to each other at right angles.

[0013] In the case where all four sides are provided, there is no such problem. This is because the two deformable members come into contact at any contacting portion.

The size of the deformable member may be approximately the same size as the side surface of the flooring material, or may be smaller if not known from above the tatami mat or the edges. The length is approximately equal to the length of the side, but may be slightly shorter. Also, a number of small objects may be provided in close contact or at intervals.

The deformable member may be inserted by holding the deformable member by hand or machine when fixing the tatami mat to the tatami floor (sewing, stapling, or the like). If holding is difficult, it is easy to temporarily fix it to the side of the flooring material with an adhesive or the like.

Since the tatami mat of the present invention is supposed to be laid tightly by deformation of the deformable member, the dimensions including the deformable member are made larger than the actual dimensions by 1 to 2 mm (introducing four sides). I do. Even if it is reduced by 1 to 2 mm due to a manufacturing error, if it can be spread smoothly and manufactured according to the dimensions, it may be deformed by 1 to 2 mm and pushed in. If it is larger than the size, it can be inserted after it is deformed with a mallet or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. FIG. 1 shows the tatami mat 1 of the present invention.
FIG. 3 is a cross-sectional view showing one example of the above. This example is a substantially square borderless tatami. The deformation member 3 is fixed to the side surface of the flooring 2. In this example, it is an insulation board. A cushion material 4 is attached to the front and back surfaces of the floor material 2. Further, as can be seen from the figure, the height of the deformable member 3 is lower than that of the floor material 2, and a space 5 is formed below. This is a portion that escapes when the deformable member 3 is deformed, so that the deformable member 3 is easily deformed and does not adversely affect the tatami table 6. Of course, the height may be the same as the floor material 3. In this figure, the tatami table 6 is omitted. This figure is a view of the frame part because the rush is cross-sectioned at right angles to the longitudinal direction.

The tatami mat 6 extends to the back surface of the flooring material 2 but may extend to the side surface. This insulation board is more flexible than ordinary flooring materials (such as veneer or plastic) and can be deformed by a force enough to insert a tatami or a mallet, so it is suitable as a plastic deformation member of the present invention.

[0019]

The present invention has the following significant effects. (1) Since the deformable member is provided on the side surface of the tatami mat, the size can be adjusted on site. (2) As the deformable member, there are a plastic deformable member and an elastic deformable member, both of which have respective advantages. (3) Since the deformable member is inside the tatami mat, it is not usually visible at all and is not conscious of the user. (4) Since the dimensions do not match on site, the worst case of remanufacturing can be reduced. (5) It is particularly suitable for rigid flooring materials such as thin tatami mats.
