DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional quilt-type feather futon, and more particularly to a feather futon that fits comfortably at bedtime, has no gaps on the body side, and is warm and comfortable. .

[0002]

2. Description of the Related Art A conventional three-dimensional quilt-type feather futon is constructed by joining the peripheral edges of a top cloth and a back cloth by sewing or other means so that the inside of the central portion of the futon except for at least the peripheral edge has a constant width (height).
In general, a grid-like compartment is formed by partition cloths crossing vertically and horizontally, and the interior is filled with feathers.
The present inventors arrange a large number of partition cloths extending in the width direction at the central portion of the futon except for at least the peripheral portion,
An improved down comforter in which the width (height) of the partition cloth is gradually reduced from the center toward the side (Japanese Patent No. 169726)
7, European Patent No. 254087).

[0003]

The conventional three-dimensional quilt-type feather futons are all made flat. That is, the partition cloth has a constant width, or at least the lower edge of the partition cloth is formed in the horizontal direction. Therefore, when the futon is hung on the body, the futon itself is not easily fitted to the body, and a gap is formed on the side of the body. Further, both sides of the futon itself are raised, so that cold outside air flows in, and the body is exposed to the outside air when the bed is turned over. This tendency is particularly noticeable when filling with plump, high-elastic feathers.

In view of the drawbacks of the prior art, the present invention provides a three-dimensional function in which the futon itself wraps around the human body, and when the outside air flows in during bedtime or turns over, the peripheral portion of the futon is turned on. It is an object of the present invention to obtain a three-dimensional quilt-type feather futon that does not turn over.

[0006]

By bending the left and right sides of the partition cloth in the width direction downward, as shown in FIGS. 2 and 9, the central portion of the futon rises in a dome shape rather than the peripheral portion of the futon. . Therefore, when you sleep with this futon, your body will be completely wrapped in the dome of the futon, and the outside air will flow in at bedtime due to the gaps on the body side and the roll-up of the periphery of the futon. Disappears.
