Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for correcting the size of a contracted tatami mat.

[0002]

2. Description of the Related Art In a typical tatami mat composed of a tatami mat and a tatami core material, the tatami mat material is made of a wood fiber board made of wood chips or a water-absorbing material such as reed. The core material and the thin veneer plate are sewn together with a wire rod.

[0003] This tatami, since the tatami core material is made of a material having a water absorption, absorption water rate I by the secular change is lowered, the tatami is outdated come and tatami core material There is a problem in that the tatami itself contracts due to contraction, and the gap between adjacent tatami mats gradually expands, making the appearance worse.

The shrinkage of the tatami mat has been a problem for a long time, but the standard of the tatami mat allows shrinkage of up to 1 mm (J
IS A 5902), there are few effective countermeasures against the shrinkage of 1 mm or less.

In particular, when used in combination with a floor heating device, the heating of the floor heating device causes the moisture in the tatami mat core to evaporate and shrink, which inevitably causes the tatami to shrink.

In order to solve this problem, for example, the tatami mat is temporarily removed from the tatami mat core, and a plate-like body having a predetermined thickness is attached to the side surface of the tatami mat core as a dimension correcting material. There is a method to extend the length and width dimensions of the timber, and then attach the tatami mat to the tatami core material again to extend and correct the length and width dimensions of the tatami mat. It is not suitable for, and the work is very difficult, and it is not practical.

Further, for example, there is a method of using a special material (generally synthetic resin) that does not shrink as a tatami core material. In this case, the special material is expensive and, in addition, a harmful gas is generated when the special material is discarded and burned. There is a drawback that occurs.

[0008] However, even if the tatami of contraction was 1mm, for example, the case of room between eight tatami mats, for a maximum of four pieces of tatami is arranged side by side, these four pieces of tatami is One not a respectively 1mm When contracted, a gap with a maximum width of 4 mm may occur,
The heat transfer material (metal plate of copper, aluminum, etc.) of the floor heating device laid on the lower surface of the tatami mat appears to shine through the gap and is very unnatural. Also, this appearance problem becomes a serious problem especially in the case of a high-class Japanese room.

Therefore, there is a demand for a method of easily extending and correcting the length dimension and width dimension of a tatami mat while it is laid.

The present invention solves the above problems,
Provided is a method for correcting the size of a tatami that is excellent in practicality, workability, and cost, and can easily extend and correct the length and width of a laid tatami mat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings illustrate one embodiment of the present invention and will be described below.

The present embodiment is a method for correcting the length or width of a tatami mat 3 composed of the tatami mat 1 and the tatami core material 2, in which the tatami mat 3 has an upper side surface on the inner surface side of the tatami mat 1. By inserting the rod-shaped body 5 having the sharpened portion 4 at the tip, the tatami mat 1 at that portion is bulged with respect to the tatami core material 2, and the length or width of the tatami 3 is corrected.

As the tatami mat 1, a commonly used one is adopted. That is, a knitted product such as rush is used.

As the tatami core material 2, a commonly used one is adopted. Specifically, a wood fiber board 6 made of wood chips or the like is used as a core material, and a shape holding plate 7 for preventing the tatami mat 3 from being crushed is provided on the upper surface of the wood fiber board 6.
A cushion material is provided on the upper surface of the shape retaining plate 7 (this cushion material is not shown), while a lining material 9 is provided on the lower surface of the wood fiber board 6, and these members are sewn together to be integrated. We are adopting the one that has become.

The shape retaining plate 7 is a veneer plate. Since the veneer plate is configured so that the fiber directions are orthogonal to each other (cross band structure), the contraction and expansion of the veneer in the direction perpendicular to the fiber is suppressed by the adjacent veneer plate, and the veneer plate in each direction of the plate surface is suppressed. Small contraction and expansion. Therefore, in the tatami mat 3 using this veneer board as the shape-maintaining board 7, the shape-maintaining board 7 located immediately below the tatami-mat 1 hardly shrinks even if the wood fiberboard 6 contracts to some extent due to aging. Therefore, the gap between the tatami mats 3 is prevented as conspicuously as possible. However, if the thickness of the veneer plate is large, the seating feeling peculiar to the tatami mat will be impaired. Therefore, it is desirable that the thickness of the veneer plate used as the shape retaining plate 7 be set thin.

Further, the tatami mat 3 has a heat transfer wire 10 formed by converging ultrafine metal wires as a thread for sewing the tatami core material 2 (for example, an ultrafine wire made of copper or aluminum having a diameter of about 120 μm is converged and twisted). The tatami mat 3 for floor heating is used. According to this configuration, the heat generated from the floor heating device installed below the tatami mat 3 is satisfactorily transferred to the tatami mat 3 by the heat transfer wire 10, which provides an excellent heating effect. It will be demonstrated. In this example,
This heat transfer wire 10 is used as a thread for stitching the wood fiber board 6 and the shape retaining plate 7, and is used as a cushion material and a lining material 9
As the thread for sewing the wood fiber board 6 and the shape-retaining board 7, a thread that is generally used is adopted.

On the long side of the tatami mat 3, a decorative edge member 11 having a pattern is provided. Also, this decorative edge member
11 is provided at a portion from the upper corner portion of the long side portion of the tatami 3 to the side surface portion of the long side portion, and is sewn integrally with the lower side portion of the tatami 3. In the figure, reference numeral 12 is a thread for sewing the decorative edge member 11 and the tatami 3 together.

The rod-shaped body 5 is made of a material that does not absorb moisture and can be bent by hand. Specifically, bamboo stick is used. Bamboo straw is inexpensive and has excellent durability, and the sharpened portion 4 can be easily formed by shaving, and it can be easily cut into a predetermined length by bending it by hand. It is extremely suitable as the rod-shaped body 5 of this embodiment. As the bamboo stick, a round bar-shaped one and a flat bar-shaped one are commercially available, but either of these can be used in this embodiment.

As the rod-shaped body 5, a rod-shaped body having a diameter of 4 mm or less or a plate-shaped rod having a thickness of 4 mm or less is adopted. This numerical value is a numerical value set so that when each tatami mat 3 contracts by 1 mm in the eight tatami mat, a maximum gap of 4 mm occurs, but this gap can be corrected even by one rod-shaped body 5. In addition, for example, a method of correcting only an arbitrary place by an arbitrary amount by using a rod-shaped body 5 having a diameter of 0.5 mm may be used.

The method for correcting the size of the tatami mat 3 will be described below.
Detailed description.

First, the size of the tatami mat 3 is measured. It is better to measure the dimensions of the tatami mat 3 in a state where the tatami mat 3 is laid in the room from the viewpoint of workability and accurate size correction. Further, the tatami 3 that is still laid in the room is not a method of measuring only the width dimension of a single tatami 3 at one place, but the tatami 3 is measured by measuring the width dimension at a plurality of locations. It is better to measure the shape of in detail. This is because the contraction of the tatami core material 2 does not mean that the tatami core material 2 is contracted uniformly, and the shape of the room itself is distorted, and therefore, the space between the tatami mats 3 may be formed. Is. It should be noted that the gap between the tatami mats 3 may be measured by a plate-shaped gap measuring gauge or the like.

Subsequently, a rod-shaped body 5 having a diameter corresponding to the contracted portion is prepared (in the case of the flat-plate-shaped rod-shaped body 5, a rod-shaped body 5 having a predetermined thickness), and the sharpened portion 4 of this rod-shaped body 5 is attached to the tatami mat 3. The tatami mat 1 on the upper side of the side surface (at the part where the decorative edge member 11 is provided, the decorative edge member 11) is pierced and inserted between the tatami mat 1 and the tatami core 2. From the viewpoint of appearance, the upper edge of the tatami 3 is the best place to insert the rod-shaped body 5.

Therefore, the tatami mat 1 is expanded by the insertion of the rod-shaped body 5, and the length and width of the tatami 3 are extended and corrected by the amount of the expansion.

If the rod-shaped body 5 is difficult to pierce, it is advisable to make a hole in the tatami-mat 1 or the decorative edge member 11 in advance by using a hole punching tool and insert the rod-shaped body 5 through the hole.

The rod-shaped body 5 may be formed by extending and correcting only an arbitrary portion of the tatami mat 3 by using the rod-shaped body 5 having an arbitrary length. Also, a method of using the long rod-shaped body 5 and extending and correcting only an arbitrary portion of the tatami mat 3 and then cutting the rod-shaped body 5 may be adopted.

The present embodiment described above more than one time, as between the tatami facing 1 and Tatamishinzai 2 in the side surface upper side of the tatami 3, the sharpened tip 4 at the tip
Simply by inserting the rod-shaped body 5 having the partial thickness of the rod-shaped body 5, can be allowed to position the site of tatami mat 1 has left the tatami core 2, thus, the length or width dimension of the mat 3 It is a method of correcting tatami mats that can be easily extended and has excellent practicality, workability, and low cost.

Further, since the rod-shaped body 5 is provided with the sharpened portion 4, the sharpened portion 4 is pierced into the tatami mat 1 to form the rod-shaped body 5.
This is a method of correcting the tatami size which is excellent in practicality and workability, in which the can be easily inserted into the inner surface of the tatami mat 1.

Since the rod-shaped body 5 is inserted into the upper side portion of the tatami 3, the rod-shaped body 5 can be easily inserted even in the laid tatami-mat 3, and the tatami 3 is The surface of the tatami mat 3 does not dent only at the insertion part of the rod-shaped body 5 and the entire surface of the tatami mat 3 in the room approximates to a flat surface, resulting in a very good appearance. It is a method of correcting dimensions.

Further, the rod-shaped body 5 of an arbitrary length and the tatami mat 1 are tatami matted.
Since adopting a configuration to insert pierce between the core member 2, utility that can be extended correct only sites that the contraction (gap prominent sites only) in accordance with the contraction of the tatami 3, the workability It becomes an excellent method of correcting tatami mats.

Further, since bamboo bar is adopted as the rod-shaped body 5, the rod-shaped body 5 is excellent in durability and has a reasonable diameter (thickness).
Can be obtained at a low price and used, and can be easily cut by simply bending it by hand, so it can be easily set to any length, and the size of the tatami mat 3 must be corrected. This is a method of correcting the tatami mat size, which is extremely practical and has an excellent workability, which allows the correction work to be performed while checking the degree.

In this embodiment, the method of correcting the tatami mat 3 contracted by floor heating is described in detail. However, in this modifying method, the gap generated due to the difference between the tatami mat 3 laid inside the room and the size of the room. It can also be applied as a correction.

That is, in the Japanese-style room in which the tatami mat 3 is laid, since the room is generally made of wood, the moisture absorption and desorption of the wood,
The size is often slightly different from the regular size due to deflection or the like.

In this respect, in the past, a tatami mat has been prepared to make a tatami mat 3 according to the size of the room or to make the tatami mat 3 larger than the regular size by about 1 mm and forcibly spread the tatami mat 3. However, in the former method, the work is very troublesome, and in the latter method, there is a problem that the dimensional error varies depending on the place and is not a fundamental solution. is there.

In the present embodiment, since only the portion of the laid tatami mat 3 which is desired to be corrected can be easily corrected, even if the dimension is wrong, the workability is remarkably superior to that of the conventional method. Can be modified.
