Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem: in a frameless tatami mat, a tatami mat surface must be folded even on a side at right angles to rush, and to this end, imitation rush made of a thermoplastic resin is partially heated, softened, and folded, which sometimes results in thermal melting or deformation of a plastic tatami mat substrate that has been widely used in recent days, and once the tatami mat substrate is melted or deformed, it cannot be used as a tatami mat any more or cannot restored. <P>SOLUTION: The method of fixing the tatami mat surface obtained by weaving the imitation rush made of the thermoplastic resin to the plastic tatami mat substrate comprises the steps of folding the imitation rush by heating and softening the same and bonding a metallic foil to at least the tatami bed at a location to which the imitation rush is folded back. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a tatami mat fixing method.

The tatami mat is manufactured by attaching a tatami mat to a tatami floor. The fixing method is generally sewing, but there are various staple methods, adhesive methods, and the like.
The tatami mats are usually cut at the side perpendicular to the rush and sewed on the edge, and at the side parallel to the rush, the tatami surface is folded and sewn.

  There is no problem with such a normal tatami mat, but there is a so-called rimless tatami mat that has no rim and has four sides of the tatami folded and fixed. In such a tatami, there is no problem because the tatami surface can be folded without folding the rush on the side parallel to the rush, but the rush must be folded at a right angle on the side perpendicular to the rush.

  Folding rushes at right angles is easy with natural rushes but difficult with plastic ones. It is difficult to fold straight, and to fix quickly, it is difficult to fix.

For this reason, imitation rushes made of a thermoplastic resin are partially heated and softened and folded. For example, a method of placing a tatami floor on an inverted tatami surface, applying a hot tub along the tatami floor and moving it linearly, softening the rush of the hot tub passing portion, and folding it back before curing.
The imitation rush as described above folds cleanly along the tatami floor. After folding, it should stick to the tatami floor as usual.

However, if a hotbed is applied along the tatami floor as described above and moved in a straight line, there will be no problem with conventional wooden floors or wooden floors. Often deforms.
When such melting or deformation occurs, it cannot be used as a tatami and cannot be restored.

  Therefore, a method of fixing a tatami mat using such a light, inexpensive and plastic floor free from ticks and using a hot water bath is provided.

  In view of the situation as described above, the inventor has completed the fixing method of the tatami mat of the present invention as a result of earnest research, and the feature is that the tatami mat woven with imitation rush made of thermoplastic resin, It is a method of fixing to a plastic tatami floor, and is that the imitation rush is folded by heating and softening, and a metal foil is adhered to at least a portion of the tatami floor where the imitation rush is folded.

  The imitation rush here may be a thermoplastic resin, and its manufacturing method, shape, color, etc. are free. For example, it is formed into a rod shape, converged into a tape shape, foamed or the like.

  As used herein, “woven tatami mat” means that the weaving method is free and woven to be used as a tatami mat. The size may be half tatami mat type, one tatami mat type, or any other size.

The plastic tatami floor may be made of thermoplastic resin, and its shape and thickness are free. Plastic cardboard type, honeycomb type and others. It may be commercially available and need not be special.
Although the thickness is arbitrary, a thin tatami mat having a thickness of about 10 mm to 20 mm is suitable, and the present invention is more effective because the thin one needs to be turned up and turned back twice. .

  The method for fixing the tatami mat to the tatami floor is not limited. Sewing, staples, fusion, bonding, and combinations thereof.

The tatami surface is folded by heating and softening.
In the present invention, since the imitation rush constituting the tatami surface is made of plastic (thermoplastic resin), it cannot be bent easily. Therefore, the bent portion is heated and softened (melted) and bent in a predetermined direction while being soft. As a heating method for softening, a hot air (such as a hair dryer) method, a hot-water method, a hot-wire method, or the like can be used, but a long hot-heat method is preferable.

  The folding is in the direction perpendicular to the imitation rush on the tatami surface, and the direction parallel to the imitation rush is easy and causes no problem. It is an edgeless tatami that needs to be folded in a direction perpendicular to the imitation rush of the tatami surface.

At least the metal foil is bonded to the tatami floor where the imitation rush is folded.
The folded portion is a wall surface of the tatami floor, which is a portion heated by hot water or the like, and is a portion where the tatami floor is softened by heat. Although the thing which stuck metal foils, such as aluminum, to the tatami floor is known, there is nothing which stuck all on the upper surface or the lower surface, and stuck on the side.

  Any metal foil may be used, but aluminum is inexpensive and easy to use. The method of sticking may be pasted with an adhesive, but it is convenient that the adhesive is applied to the back surface of the aluminum foil.

  If the aluminum foil is affixed to the side of the tatami floor, the heat transfer rate of the aluminum foil is large even if a hot metal touches that part, so that heat is immediately transferred to the entire aluminum foil, resulting in high heat locally. do not become. Therefore, the plastic tatami floor on the back side does not melt. For example, a rush heated to about 200 ° C as the melting temperature of plastic and the rush directly contacting it melts, but when the heel touches aluminum for a short time, even if the contacted part is 200 ° C, the heat is instantly transferred to the entire surface and the back surface. Then it feels like it will be below 100 ° C.

  As described above, the metal foil is only required to be heated, but may be attached to other portions. It may be advantageous for reinforcement or other purposes.

The fixing method of the tatami mat of the present invention has the following great advantages.
(1) The plastic floor does not melt or deform even when using a heating tool such as hot water. Therefore, an inexpensive and lightweight tatami floor can be used.
(2) Even plastic rushes that are difficult to fold can be easily folded using a hot iron, so the edgeless tatami can be made beautiful.
(3) Even a thin tatami mat that needs to be bent twice can be cleaned.

Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings.
1-5 is a figure which shows an example of this invention fixing method. FIG. 1 is a plan view of a corner where the back of the tatami mat 1 is placed and the tatami floor 2 is placed thereon. The imitation rush 3 on the tatami surface runs left and right in this figure. Since the upper side 4 of the tatami floor is parallel to the rush, the tatami table 1 can be easily folded back toward the edge. Since the right side 5 is perpendicular to the rush, it is difficult to bend.
An aluminum foil 6 is attached to the right end of the tatami floor 2.

  FIG. 2 is a perspective view of FIG. It can be seen that the aluminum foil 6 is applied across the side surface and the top and bottom of the tatami floor 2.

FIG. 3 shows a state where a hot metal 7 is placed at the right end of the tatami floor 2 of FIG. 2 and the part to be bent is heated and softened (partially melted). Since this rod 7 has two heating feet 8, two softening lines can be obtained in one progression. The interval between the two heating feet 8 corresponds to the thickness of the tatami floor 2.
At this time, even if the heating bowl 7 is in contact with the tatami floor 2, the tatami floor 2 does not melt because the aluminum foil 6 exists.

  FIG. 4 shows that two softened portions (here depicted as concave portions) 8 are formed by the heating rod 7. This may be folded back to the tatami floor and fixed with, for example, a fastener 9.
