Abstract

PROBLEM TO BE SOLVED: To provide a light and warm down quilt which achieves a better swelling of stitches in a quilting structure with limited amount of down. SOLUTION: A down quilt 1 has a surface 3 and a lining 7 which are formed into a bag by sewing the perimeter of the quilt (lines A, H and G). A mid fabric 5 is arranged between the surface 3 and the lining 7 by sewing it alternately on the surface 3 or on the lining 7 along the lines B, C, E and F so that five mid bags are formed between the fabrics. The individual mid bags are packed with down 9 and made voluminous and plump as a whole containing portions on the lines B, C, D, E and F of stitches.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a duvet. In particular, it relates to a light, warm duvet with a well-swelled seam of the quilted structure with a small amount of down.

[0002]

2. Description of the Related Art A duvet is formed by dividing a space between an outer material and a lining formed into a bag shape by sewing the periphery into a plurality of inner bags, and filling the inside with a down. Modern comforters are mostly duvets because they are lighter and warmer than cotton quilts.

[0003]

The inner bag of the duvet is for uniformly dispersing the down in the duvet throughout the duvet. However, the thickness of the futon tends to be thin at the seam portion of the inner bag, and conventionally, a gore was inserted into this portion to increase the volume. However, the width of the gore was limited, and as the width was increased, it became heavier.
Therefore, a duvet with a light weight and a large volume could not be obtained.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a light and warm duvet in which a seam of a quilted structure is well swollen even with a small amount of feathers.

[0005]

In order to solve the above-mentioned problems, a duvet of the present invention divides a space between a surface material and a lining, which are formed into a bag shape by sewing around the periphery, into a plurality of middle bags, into which a feather is inserted. A quilt filled with a sewn-in cloth; alternately, the sewn-in cloth is sewn to the outer material or lining to arrange the inner material in a polygonal line between the outer material and the lining; A bag is formed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the entire structure of a duvet according to one embodiment of the present invention. (A) is a cross-sectional view, (B) is a front view, and (C) is a back view.

[0007] This duvet 1 has a periphery (lines A, H, G,
K) is provided with a front material 3 and a lining 7 sewn into a bag shape. Then, between the outer material 3 and the lining 7, the inner material 5 is alternately sewn to the outer material 3 or the lining 7 with lines B, C, D, E, and F. Therefore, five inner bags are formed between the cloths in the cross section of FIG. Each inner bag is filled with feathers 9 and has a plump volume as a whole including the seam lines B, C, D, E and F.

When viewed from the surface of the duvet 1, FIG.
As shown in the figure, two stitches C and E can be seen vertically, and two stitches can be seen horizontally.
The seams I and J of the book are visible. Of these, the horizontal stitches I and J are sewn by a conventional method of inserting a gore to make the volume as large as possible. Details of the gore will be described later with reference to FIGS.

When the back of the duvet 1 is viewed, as shown in FIG. 1C, three stitches B, D and F can be seen vertically, and two stitches I and J can be seen horizontally. What is important here is that the seams C and E on the front surface and the seams B, D and F on the back surface are considerably displaced. That is, as can be seen from the cross section of FIG. 1A, the seam C is almost at the center between the seams B and D, the seam D is almost at the center between the seams C and E, and the same applies to E and F hereinafter. is there. Therefore, seams B, C, D,
A sufficient volume can be realized without the bulging of each middle bag being hindered at the portions E and F.

In the duvet of this embodiment, the horizontal seam I,
J has a volume as much as possible with a gore as before. FIG. 2 is a plan view showing the arrangement of the gores of the outer material. Gore 1
Reference numeral 1 denotes a tape such as a polyester mesh, which is sewn to seams I and J. Part 11a above the seam
Is narrow, 10 mm in this example. The width of the portion 11e below the seam is wide, 67 mm in this example.

One gore 11 is sewn between seams E to C (for example, 50 cm in width). Both ends of the gore upper portion 11a are folded back in a triangle (portion 11b), and are sewn with a line 11c from above the folded gore.

This portion becomes a small hole even after the seams of the front and back middle gussets are sewn, and finally serves to pass a tube for blowing feathers. Both ends 11d of the gore 11 are about 75mn
It is flickering in width. The portion 11d and the lower portion 11e are sewn to a gore of another fabric in a later stitching step.

FIG. 3 is a plan view showing the arrangement of the gores on the middle ground surface. A gore 13 is sewn on the front and back of the middle ground along seams I and J. The gore 13 has one tape in the overall length. However, the lower wide portion 13b has seams E and C on the front side and seams D on the rear side.
There is a cut 13c at the portion. The back has two gores on both sides of the seam D between BD and DF. This cut 13c is for pulling out the lower part 13b of the gore to the left and right of the seam. In this example, the width of the upper part 13a of the gore is 10 mm, and the width of the lower part 13b is 25 mm.
It is.

FIG. 4 is a plan view showing the arrangement of the gores on the lining surface. The gore 15 of the lining 7 is sewn in the same form as the gore 11 of the outer material 3. However, it is sewn in four places (the width of one place is 37.5 cm in one example) in the whole width.

Next, the procedure of sewing the duvet of this embodiment will be described. First, the fabric is cut, and seams B and C
Draw I, J, etc. Next, the middle fabric 5 is placed on the lining 7, the seam D is aligned, and sewing is performed with a sewing machine.

Next, the lining 3 is placed on the middle ground 5, and the seams C and E are sewn together. Next, the gore between the lining 3 and the middle ground 5 is stitched between seams C and E. Next, Nakachi 5
And the lining 7 are sewn together at seams B and F. Next, the gore between the middle ground 5 and the lining 7 is stitched between seams B and D and between D and F. Next, the seams A, G, H, and K at both ends are sewn together. At this time, several holes for the feather blowing tube (diameter 30 mm) are opened. Next, feathers of a predetermined weight are blown into each middle bag. In this case,
A known feather filling machine is used. After the feathers have been filled, finally the holes in the outer periphery seam of the feather filling tube are stitched together to complete.

In this embodiment, a single comforter (1.5 m wide × 2.1 m long) can provide a sufficient volume to the comforter even with a feather filling amount of 1.2 kg, and a total weight of 2.
With a lightness of 4 kg, a sufficiently warm futon was realized. In addition,
Conventionally, the feather filling amount was 1.4 to 1.5 kg.

[0018]

According to the duvet of the present invention, the inner fabric is alternately sewn to the outer fabric or the lining to arrange the middle fabric in a polygonal line between the outer fabric and the lining. Since the inner bag is formed in between, the seams of the quilted structure can be well swelled even with a small amount of feather, and a light and warm duvet can be provided.
