  Therefore, the top surface futon part can insert the bolt screw of the fixing means into the cut line, so the cut line of the top surface futon part is in close contact with the bolt screw, and the heat of the kotatsu is external to the kotatsu futon. It is difficult to leak. In addition, as described above, since the short sides of the side futon portions are sewn to the respective sides of the top surface futon portion, there is no large hole for inserting the fixing means unlike the conventional kotatsu futon. .

  In addition, the manufacturing method of each side futon part includes a step of preparing a side bag made of trapezoidal shape, a main body part made of the same trapezoid as the shape of the side bag, and a long side of the main body part. A step of preparing a side cotton provided with a shorter and symmetrical folded portion made of a trapezoidal shape, a step of placing the side cotton in a side bag, and folding the folded portion back to the main body. And a step of overlapping.

  For this reason, a large amount of cotton, that is, an amount of cotton in which the main body and the folded portion overlap, is arranged at the end of the side duvet so that it is difficult for the heat of the kot to leak to the outside during use. It has become. Furthermore, a large amount of cotton can be easily arranged at the end of the side duvet, and a large amount of cotton does not move from the end of the side duvet during use.

  Hereinafter, an embodiment of a method for producing a kotatsu futon according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the top surface futon portion 1 includes a top surface bag 10 having a rectangular shape. Cotton 11 is placed inside the top bag 10. In this embodiment, the top | upper surface futon part 1 consists of squares, and the length L1 of each edge | side 1a is about 80 cm. The length of each side 1a of the top surface futon part 1 is adjusted to the length of the top plate of the kotatsu. Therefore, when the top plate of the kotatsu is rectangular, the top surface futon part 1 is rectangular.

  The top surface futon part 1 is provided with a single cut line 12, 12 in a direction orthogonal to the sides 1a, 1a with respect to the pair of sides 1a, 1a facing each other. In the present embodiment, the length of each cut line 12 is about 10 cm. In the top surface futon portion 1, a hem fabric 12 a is sewn around the cut line 12. Furthermore, in this embodiment, the top surface futon part 1 is quilted.

As shown in FIG. 2A, the side bag 20 has a trapezoidal shape, and has a short side 20a, a long side 20b parallel to the short side 20a, and a pair of slopes connecting the ends of the short side 20a and the long side 20b. Sides 20c, 20c.

  The length L1 of the short side 20a of the side bag 20 is the same as the length L1 of each side 1a of the top surface futon part 1, and is about 80 cm in this embodiment. In the present embodiment, the length L2 of the long side 20b of the side bag 20 is about 200 cm. The height L3 of the side bag 20 is about 60 cm.

  As shown in FIG. 2B, the side cotton 21 includes a main body portion 210 and a folded portion 211 connected to the main body portion 210. The main body part 210 and the folded part 211 have the same thickness. The main body 210 has the same trapezoid shape as the side bag 20. Therefore, the length L1 of the short side 210a of the main body 210 is about 80 cm, and the length L2 of the long side 210b is about 200 cm.

  The folded portion 211 is shorter than the main body portion 210 and has a trapezoidal shape symmetrical to the main body portion 210. For this reason, the length L2 of the long side 211b of the folded portion 211 is about 200 cm. The height L4 of the folded portion 211 is about 1/3 of the height L3 of the side bag 20 and is about 20 cm. The length L5 of the short side 211a of the folded portion 211 is about 160 cm.

  The side cotton 21 is placed in the side bag 20. The side cotton 21 is overlapped with the folded portion 211 folded back to the main body portion 210. Therefore, the side cotton 21 has a bulky portion where the main body portion 210 and the folded portion 211 overlap.

And folding the folded portion 211 on the main body portion 210 to overlap.

  As shown in FIG. 3, the kotatsu futon is composed of a top surface futon part 1 and four side surface futon parts 2. In the kotatsu futon, the short sides 2a of the side surface futon portions 2 are sewn to the sides 1a of the top surface futon portion 1, respectively. And the kotatsu futon is sewn on the inclined side 2c of each side futon part 2, respectively.

  Therefore, the manufacturing method of the kotatsu futon includes the step of preparing the rectangular top surface futon part 1, the short side 2a having the same length as each side 1a of the top surface futon part 1, and the short side 2a. A step of preparing four side-face futon portions 2 having a trapezoidal shape having a long side 2b and a pair of inclined sides 2c connecting the ends of the short side 2a and the long side 2b; A step of sewing the short side 2a of each side futon part 2 to the side 1a, and a step of sewing the inclined side 2c of each side futon part 2;

  As shown in FIG. 4A, the kotatsu futon becomes a square by the long sides 2 b of the four side futon portions 2. And the part 2c which connects each corner | corner of the top | upper surface futon part 1 and each corner | corner of the side surface futon part 2 turns into a sewing part. Therefore, this sewn portion functions as a broken line of the kotatsu futon after completion so that the heat of the kotatsu does not easily leak to the outside during use.

  As shown in FIG. 4 (B), the amount of cotton put into each of the top surface futon part 1 and the side surface futon part 2 can be made different. Since the top cover 1 is covered with a top plate, the amount of cotton 11 can be reduced, and the side cover 2 can be increased in the amount of cotton 21 so that the heat of the kot does not leak outside. .

  As shown in FIG. 4 (B), a large amount of cotton 21, that is, the amount of cotton 21 in which the main body portion 210 and the folded portion 211 overlap each other is arranged at the end of the side duvet portion 2. , Kotatsu's heat is difficult to leak outside. Furthermore, since the main body part 210 and the folded-back part 211 are connected, a large amount of cotton 210, 211 can be easily disposed at the end of the side duvet part 2, and a large amount of cotton 210, 211 is used in use. However, it does not move from the end of the side futon part 2.

  As shown in FIG. 5, the kotatsu 3 includes a pair of fixing means 4 for detachably fixing the kotatsu main body 31 and the top plate 30. The fixing means 4 includes a bolt screw 41 attached to the kotatsu main body 31 and a nut 40 attached to the top plate 30. The bolt screw 41 is fixed to the kotatsu main body 31 via a fixture 42 attached to the kotatsu main body 31.

  The fixing means 4 fixes the kotatsu main body 31 and the top plate 30 by screwing the bolt screw 41 and the nut 40 together. The kotatsu 3 is configured so that the kotatsu main body 31 and the top board 30 are connected by the fixing means 4 so that the top board 30 is not displaced from the kotatsu main body 31.

  In use, a kotatsu futon is hung on the kotatsu body 31. The bolt screw 41 of the fixing means 4 is inserted through the cut line 12 of the top surface futon part 1. Therefore, as shown in the enlarged view drawn inside the circle of FIG. 5, the cut line 12 of the top surface futon part 1 is in close contact with the bolt screw 41, and the kotatsu heat leaks to the outside as compared with the conventional kotatsu futon. It has become difficult. Moreover, as above-mentioned, the big hole for inserting the fixing means 4 does not open like the conventional kotatsu futon.

  As mentioned above, although preferable embodiment of this invention was described, the structure of this invention is not limited to these embodiment.
