Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a duvet having a partition wall that connects the outer fabric and the lining fabric at a distance.

The duvet according to the present invention can be used even if the sleeper moves.
The feathers stored in the feather storage compartment are not unevenly distributed,
The futon as a whole has extremely high heat retention.

[Conventional technology]

2. Description of the Related Art A duvet is known in which the outer fabric and the lining fabric are connected by quilting after the feathers are stored between the outer fabric and the lining fabric. Hereinafter, this will be referred to as the "first known duvet." The cross section of the down storage compartment in this first known down comforter has various shapes such as a lattice shape and a regular hexagonal shape.

On the other hand, there is a horizontal partition wall at a position slightly toward the center of the front and rear ends perpendicular to the longitudinal direction of the futon, and a diagonal partition wall extending diagonally up and down from the horizontal partition wall, respectively. A duvet is known in which a plurality of down storage compartments are formed by connecting the backing fabric at a distance from the duvet.
62-68671). Hereinafter, this will be referred to as the "second known duvet." The cross section of the down storage compartment in this second known down comforter has an isosceles triangular shape,
The shape is a right triangle, a trapezoid, or a modified quadrilateral.

[Problem that the invention attempts to solve]

The first known down comforter has the following problems. That is, in the first known duvet, the distance between the outer fabric and the lining fabric gradually decreases as you approach the quilting area from the center of the down storage compartment.
The amount of feathers stored in the feather storage compartment is large in the central part of the feather storage compartment, and gradually decreases as it approaches the quilting part. Therefore,
The first known down comforter significantly lacks heat retention in the vicinity of the quilted portion that constitutes the down storage compartment. Note that the cross-sectional shape of the down storage compartment in the first known down comforter is merely a matter of design, and there is no functional difference whether it is a lattice shape or a regular hexagonal shape.

On the other hand, the second known duvet has the following problems. That is, in the down comforter's down storage compartment, each feather is stored with a sufficient spread, but the amount of storage is such that adjacent feathers come into light contact with each other. Therefore, as the sleeper moves, the feathers stored in the feather storage compartment also move, but when these feathers hit a partition wall, they are bounced in the opposite direction, and if there is another partition wall within the range of the rebound force, , it is bounced back by the partition wall and gradually moves in the direction where there is no partition wall. In other words,
Partition walls act as obstacles, and the smaller the angle between adjacent partition walls, the greater the effect. In the second known down comforter, the cross section of the down storage compartment is an isosceles triangle, a right triangle, a trapezoid, or a modified quadrilateral, so the angle between adjacent partition walls varies in size.
As a result, in corners where the angle between adjacent partition walls is small, the amount of feathers is smaller than at corners where the angle between adjacent partition walls is large, resulting in an uneven amount of feathers. It turns out.

In addition, in the second known duvet, the partition wall is provided in a direction perpendicular to the outer fabric and the lining fabric, so
This means that there are no feathers at all in the area where the partition cloth is present.

[Means to solve the problem]

As a result of various studies on the problems of the prior art described above, the inventor of the present invention specified the cross-sectional shape of the feather storage compartment to be a regular hexagon, and devised a way to attach the partition wall. We succeeded in creating a duvet that solved these problems.

That is, the down comforter according to the present invention has a partition wall 3 that separates and connects a front fabric 1 and a lining fabric 2, and has a large number of down storage compartments 6 formed by the partition wall 3. has a regular hexagonal cross section, and the partition wall 3 is formed obliquely with respect to the outer fabric 1 and the lining fabric 2.

In the present invention, seam allowances 4 are provided at the top and bottom of the partition wall 3, which are folded horizontally with respect to the outer fabric 1 and the lining fabric 2. The partition wall 3 is formed by sewing or bonding the seam allowance 4 to the outer fabric 1 and the inner fabric 2, respectively.

Note that 5 in the figure indicates a nozzle insertion hole. Feathers are stored in the feather storage compartment through this insertion hole 5.

[Effect]

In the present invention, since the feather storage compartment 6 has a regular hexagonal cross section, each corner has an equal angle of 120 degrees. Therefore, since there is a distance between the feathers that hit one side of the partition wall 3 constituting the feather storage room 6 and the feathers that hit the adjacent partition wall 3, the adjacent partition wall 3 is unlikely to act as an obstacle. . Therefore, even if the feathers stored in the feather storage compartment 6 move as the sleeper moves, the movement of the feathers is extremely small, and since each corner is at an equal angle, There is no deviation in the amount of feathers.

In addition, since the partition wall 3 is formed obliquely with respect to the outer fabric 1 and the lining fabric 2, feathers are present above and below the partition wall 3, which is significantly different from the area where the partition wall 3 does not exist. Therefore, there will be an amount of feathers without .

〔effect〕

Since the duvet according to the present invention has the above-described configuration and function, it can achieve the following effects. That is, in the down comforter according to the present invention, the amount of down feathers stored in the down storage compartments is almost evenly distributed in each corner, so that the first known down comforter and the second known down comforter are not biased. It has much better heat retention than .
