Description

[Detailed Description of the Invention] The present invention relates to improvement of a duvet, and an object of the present invention is to provide a duvet that has a structure with good heat retention effect and at the same time facilitates the process of assembling the duvet.

Conventionally, down comforters wrapped in waterfowl feathers have been used, but the upper and lower fabrics are sewn into sections to prevent the feathers from being concentrated to one side of the futon. As a result of processing, the seams become thin and have no feathers, resulting in poor heat retention efficiency. The above problem can be solved by inserting a gusset between the upper fabric and the lower fabric at the sewn part, but in this case, the gusset that should form the central compartment is sewn up before filling with feathers, and the central compartment is formed. I can't do it. That is,
If the center section is formed without being filled with feathers, it will not be possible to fill the center section with feathers, and the process of assembling the futon will be complicated because the feather insertion and sewing will have to be carried out alternately. This increases manufacturing time and labor costs.

In view of the above-mentioned problems, the present invention aims to provide a duvet that has a gusset between the upper fabric and the lower fabric, reduces the number of alternating operations of feather inserting and sewing, and facilitates the futon assembly process. A double structure gusset is provided so as to form a passage opening in the central section and extending to the peripheral edge, and the opening in the peripheral edge of the double structure is closed by suture.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway plan view of a futon. 1 is the upper cloth, 2 is the lower cloth, and both cloths 1, 2
A gusset is inserted and sewn in between to form compartments (in this example, there are 16 compartments, 40% in the vertical direction and 40% in the horizontal direction), and each compartment is filled with feathers. Regarding the above-mentioned partitions, the one adjacent to the peripheral edge 3 of the futon is called the peripheral partition 4, and the one surrounded by the peripheral partition 4 is called the central partition 5. Between the two cloths 1 and 2, The first gusset and second gusset that are interposed and sutured in the lateral direction become double gussets 6, 7, forming a passage 8 and connecting one inner side to the central partitions 5, 5... On the other hand, inner openings 9, 9, . . . are formed, each opening at one location. In addition, the third gusset 10 in the horizontal direction and each gusset 11 in the vertical direction,
11, 11 are normal gussets for connecting and stitching between the upper fabric 1 and the lower fabric 2. When sewing each vertical gusset 11, the center portions (arrow A) of the double gussets 6, 7 are Although the passage 8 is stopped by suturing, the intersections in the middle (arrow B) of the passages 8, 8, . . . must be constructed without suturing.

By the above-mentioned sewing, the bag of the futon is sewn leaving the peripheral edges 3 of the upper cloth 1 and the lower cloth 2, and the bag is filled with feathers 12. The feathers 12 are attached to each central section 5,5
Insert the blowing pipe a connected to the tip of a feather blowing jig (not shown) into the passages 8, 8, which open at the peripheral edge 3 of each double gusset 6, 7, and A predetermined amount is filled from a through the inner opening 9, and each peripheral edge section 4 is filled with each predetermined amount from the unsewn edge opening of the peripheral edge 3. Thereafter, the peripheral edges 3 of the upper fabric 1 and the lower fabric 2 are sewn together to close the peripheral edge section 4, and at the same time, the outer ends of each passage of the double gussets 6 and 7 are also sewn closed to form a duvet. .

When the duvet having the above structure is filled with feathers 12 in the central partition 5, when the blowing pipe a of the feather blowing jig is filled and then pulled out from the passage 8 of the double gussets 6 and 7, the double gussets 6 and 7 are pulled out. , 7 on both sides of partitions 4,
The expansion of the feathers 12 filled in the center section 5 presses the passage 8 from both sides and closes the inner opening 9 at the same time. It will not invade the periphery of the heavy gussets 6, 7 and become uneven.

Next, FIGS. 4 and 5 show the feathers 1 for the center section 5 when the number of sections of the futon is increased, respectively.
2 shows an example of filling, where the solid arrow indicates the blowing path, and the present invention can be achieved by configuring the gusset corresponding to the blowing path as a double gusset.

As explained above, in the duvet of the present invention, the duvet surface is divided into sections through the gusset between the upper and lower cloths, and each section is filled with a predetermined amount of feathers. It does not become biased in one part, and at the same time, since the division part is formed with a gusset, there is no thin part associated with stitching between the upper and lower fabrics, and the heat retention effect is high. In addition, the duvet of the present invention is provided with a double-layered gusset to form a passage that opens in the central compartment and extends to the peripheral edge. Since the part can be filled with feathers from the peripheral edge, the gussets other than the peripheral edge can be sewn prior to filling with feathers. Therefore, the practical effects of the present invention are extremely great, as the number of alternating operations between feather inserting and sewing can be reduced, and work efficiency is improved.
