Description

[Detailed description of the invention] The present invention relates to a method for repairing tatami mats.

If there is a small burn on the surface of the tatami due to tobacco, incense sticks, etc., the way to repair this is, for example, with Endurance 11.
There is an invention described in Japanese Patent No. 56-54421. This method involves cutting out the charred part of the tatami surface by cutting out the woven rush, pushing the cut-out ends on both sides downward and pushing it out to the back side, creating a gap in the turning part for inserting the rush element, and creating a gap for inserting the rush element. Then, by using a repair thread element of an appropriate length, the central part is laid horizontally over the warp threads, and
A repair method is disclosed in which both ends of the warp are engaged with the lower side of the warp adjacent to the same warp through the above-mentioned gap. However, with this method, it is time-consuming to cut only the surface of the rush leaving the warp threads, and the cut ends are created in a step shape on the back side of the tatami mat. The drawback was that the back side of the camera could not be used. The present method eliminates these drawbacks of the conventional method, and its gist is to make incisions parallel to the direction of the warp threads with a knife on the part of the tatami surface where the scorch marks exist, and to cut the warp threads on the left and right sides of the incisions. Cut out an amount corresponding to the length of the cut and press the uncut end on the front side downward to push it into the back side, creating a gap for inserting the repair rush at the intersection of the rushes that make up the tatami surface. The method for repairing a tatami surface is characterized in that a repair piece of an appropriate length is inserted into the gap and engaged with the lower side of the warp adjacent to the gap. This will be explained in detail below.

To explain one example of the method of repairing the tatami mat of the present application, Fig. 1 shows a case where there is a scorch mark 3 on the surface side 2 of the tatami mat 1 and the size of this scorch mark is within one pile of the tatami mat 1. This shows the repair method. In such a case, as shown in FIG. 2, the surface side 2 of the peak 10 where the scorch mark 3 exists is longer than the length of the scorch mark 3 in the warp direction, and the blade is cut parallel to the warp thread 5.6. At the same time, make a cut 8 by cutting the warp threads 5.6 on both sides of the cut 8 by the same dimension as the cut 8.
Cut and remove. It is desirable that the cuts 8 cut only the front side 2 of the tatami mat, but this is not an essential requirement, and the back side 2a may also be cut.

Next, the cut end of the rush cut by the notch 8 is
A gap for inserting the repair rushes 13 described later is created by pushing them between the rushes forming the back surface 2a of the tatami surface 1 using an appropriate tool such as a bottle set, and pushing them out to the lower surface of the back side 2& of the tatami surface 1. form 9. On the other hand, the warp threads 4.4' and 7.71 of the left and right peak parts 11.12 adjacent to the peak part 10 are interposed between the front and back surfaces to stop weaving the rush, but there are scorch marks 3. Prepare an appropriate number of repair rugs 13 cut slightly longer than the mutual distance of the warp threads 4.7 on the side close to the peak 10, and cut both ends 13a, 13b of these so that they are parallel to the grain of the tatami. Insert into the gap 9 formed by the above pushing operation,
The operation of engaging the ends 13a and 13b is repeated so that they are located below the warp threads 4.7. In this way, the repair is completed when all the gaps 9 are completely filled with the repair tools.

In the above embodiment, the repair method of the present invention is applied to the case where the scorch mark is present in one mountain part, but next, the method according to the present invention is applied to the case where the char mark exists over two mountain parts. An example will be explained. That is, to explain the repair method when the burn mark exists over two peaks 20.32, this case is also essentially the same as the case where the burn mark exists only in one peak. In Fig. 2, a cut 28 is made with a knife in the scorch mark 23 of the tatami facing 21 almost parallel to the warp threads 25, 26, etc., and the same length as the cut 28 is made in the crest 20, 32 where the scorch mark 23 belongs. The warp threads 25.25' and 26.26' passing through are cut and removed. Next, the cut ends 33, 33' of the rushes cut by the notches 28 are pushed between the rushes forming the back side of the tatami mat side 21 using a suitable tool such as tweezers, and By extruding it to the bottom surface, repair gusset 34.35,
A gap 29 for insertion such as... is formed. On the other hand, a mountain portion 20a that momentarily contacts the mountain portion 20.32 where the scorch mark 23 exists,
Among the warp threads 24.24' and 27.271 passing through the inside of the thread 32a, the gap 29 is placed below the warp thread 24.27 on the side closer to the peak 20.32 where the scorch mark 23 exists. The repair tool 35, 34 is engaged through the repair tool, and the other ends of the repair tool are interlocked by crossing each other to form a valley 36 between the peaks 20, 320. be. In this way, the repair is completed by repeating the same operation for each gap B229 on both sides, using the same number of repair tools as the gaps 29, which are slightly longer than the width of the peak. In addition, at this time, Yamabe 2
If a thin rod made of plastic or bamboo is inserted into at least one of the threads 0 or 32 in the same direction as the warp threads 25 and 26, the workability will be improved. As the repaired surface is stepped on by foot, the degree of engagement is further strengthened.

The method of repairing the original bone, which consists of the above-mentioned steps, has the advantage of being able to use the back side by turning the tatami over, as it does not create a stepped part on the back side of the tatami mat, and has good operability and work efficiency. It has the effect of being expensive. By stepping on the repaired surface, the degree of engagement is further strengthened and it acquires the same durability as other tatami mat surfaces. Also, when you turn it inside out, the cut edges that come out on the surface are in a state where they are butted against each other, so by gluing these parts or stepping on them with the soles of your feet, you can engage them with the rush on the bottom side. will not cause any inconvenience.
