Description

Detailed Description of the Invention "Field of Industrial Application" This invention relates to a down comforter, and more specifically, when a partition section formed by three-dimensional quilting is filled with down, etc., each of the adjacent partition sections The present invention relates to a down comforter that can prevent the movement of feathers, etc. during use.

``Prior art'' As a technique for applying three-dimensional quilting to down comforters, the applicant has proposed, for example, Utility Application No. 39391 (1983) and Japanese Patent Application No. 1983 (1983).
Many proposals have already been made, such as 55122.

The above technique involves sewing one lengthwise edge of the vertical and horizontal partitions onto the side fabric in advance, making incisions in the required areas, and raising the incised partition fabric upright. to form two side fabric halves, the inner surfaces of these two side fabric halves are faced to each other, and the other edges of each partition fabric piece are fastened to each other along their length to create a futon. configured to form sides.

By the way, in order to fill the partition with feathers, etc., it is necessary to fill the gap between the end of the raised partition cloth and the side ground of the other partition cloth against which the end of this partition cloth is pushed. A conceivable method is to insert a hose for force-feeding feathers, etc. with compressed air into the small gap formed, thereby sequentially force-feeding the feathers, etc. into the partitioned sections.

``Problems to be Solved by the Invention'' However, when a down comforter is actually used, feathers, etc. move from the gaps to adjacent partitions, making the bulk uneven and the heat retention depending on the location. There were problems such as worsening of

This invention deals with the above-mentioned movement of feathers, etc. between the partitions in the down comforter, and the resulting deterioration of heat retention due to non-uniformity in the bulk of the feathers, etc.

"Means for Solving the Problem" This invention provides vertical and horizontal partitioning fabrics that partition adjacent partitioning sections by overlapping two pieces of gusset fabric and using feather pressure between the two pieces of gusset fabric. The insertion path is formed by providing an insertion path for a hose, and the insertion path is provided with openings communicating with each adjacent partition section spaced apart from each other, and the intersection where the partition cloth crosses is formed by connecting one of the intersecting partitions. A cut is formed on the side of the cloth, and the end of the other partition cloth is fixed to the periphery of the cut in the thickness direction of the futon, so that the insertion paths formed in the vertical and horizontal partition cloth are communicated with each other. be.

"Function" When the down comforter is configured as described above,
A hose for pressure-feeding feathers is inserted into the insertion path so that the hose faces into each partition from the opening, and feathers are sequentially force-fed from the hose into the partitions to fill them. In addition, when using a down comforter, the partition fabric at each intersection is fixed in the thickness direction of the comforter, so feathers, etc. move between the partitions and reduce the bulk depending on the location. can be effectively avoided.

"Embodiment" FIGS. 1 to 12 show an embodiment of the present invention, and reference numeral 10 in the figures indicates a down comforter.

As shown in FIG. 2, the down comforter 10 has two upper and lower rectangular side pieces 11a and 11b, and is arranged in a grid pattern vertically and horizontally between the side pieces 11a and 11b. It consists of a partition cloth 12 which is arranged to form a partition section A, and feathers etc. filled in the partition section A.

The partition cloth 12 consists of a vertical partition cloth 12a and a horizontal partition cloth 12b. The vertical partition cloth 12a
As shown in FIGS. 3 to 8, a pair of vertically partitioned cloth pieces 12a 1 have one edge 12a ₃ along the length direction sewn to the inner surface of each of the side fabrics 11a and _11b ,
It consists of a pair of vertically gusseted cloth pieces 12a 2 with a longitudinal center portion 12a ₄ sewn onto the inner surface of each side fabric 11a, _11b . The pair of vertical partition cloth pieces 12a ₁ and the pair of vertical gusset cloth pieces 12a ₂ are connected to each other by sewing the other free edges 12a ₅ to each other in the length direction. In this case, the vertical partition cloth piece 1
2a ₁ has a width that is approximately 1/2 of the thickness of the futon, but the vertical gusset cloth piece 12a ₂ has a width that is approximately the same as the thickness of the futon, and the other edges 12a ₅ are sewn together. An insertion path _B1 for a feather pressure feeding hose is formed in the vertical partition cloth piece 12a. The vertical gusset cloth piece 12a ₂ is disposed second from one side in the width direction (the right side in FIG. 1A), and the other three are the vertical partition cloth pieces 12a ₁ .

Further, as shown in FIG. 9, the horizontal partition cloth 12b is composed of a pair of horizontal partition cloth pieces 12b ₁ and a pair of horizontal gusset cloth pieces 12b ₂ , like the vertical partition cloth 12a. One of the differences from the vertical partition cloth _12a is that, as _shown in FIG. It is a point. The other difference is that the horizontal gusset cloth piece 12b ₂
In the hose insertion path _B2 formed by
As shown in Figure A, an opening C that allows the hose to face the partition section A adjacent to both sides of this insertion path _B2 is formed by making a cut E (for example, Figure 1 I and Figure 3 I). ). It is preferable that the openings C are spaced apart from each other as much as possible within the same row of the partition section A (in the vertical direction in FIG. 1A). Further, this opening C is formed by making a cut E at the corresponding location between the horizontal gusset cloth pieces 12b ₂ and the other edge 12b ₅ and not sewing the part of the cut E. In this case, the size of the opening C is formed such that the interval between the notches E is about 6 cm, but it is sufficient as long as it is large enough to allow the feather pressure feeding hose to face into the partition section A, for example. It is also possible to simply make one incision.

On the other hand, an intersection D where the partition cloth 12 intersects
is formed by fixing each partition cloth 12 in the thickness direction of the futon. That is, _{the vertical partition cloth piece 12a 1 located at} the right end in FIG. It's getting old. In other words,
This intersection D ₁ is formed by cutting E ₁ on both sides of the horizontally gusseted cloth piece 12b ₂ along both sides of the seam S of the horizontally gusseted cloth piece 12b ₂ , as shown in FIG. 3B.
(Fig. 11) The ends of the vertically divided cloth pieces _12a1 , which have been inserted and stood up, are sewn in the thickness direction of the futon.
It is formed to have a hose insertion path _B2 in the width direction of the futon. As shown in FIG. 3A, the other edges 12b ₅ of the upper and lower horizontal gusset cloth pieces 12b ₂ are connected to each other, and the other edges 1 of the upper and lower vertical partition cloth pieces 12a ₁ are connected to each other.
2a and ₅ are sewn together in the length direction, so that the side fabrics 11a and 11b are connected to each other.

In addition, in FIG. 1A, the vertical gusset cloth piece 12a ₂
and the horizontal gusset cloth piece _12b2 located above is the fourth
As shown in the figure, they are sewn to form an intersection _D2 . One side of this intersection _D2 (the left side in Fig. 4) has a horizontal gusset cloth 1 as shown in Fig. 4B.
On one side of 2b ₂ raised up, place a horizontal gusset cloth piece 12b ₂
Cut E ₁ along both sides of seam S (12th
Vertical gusseted cloth piece 12 held upright after inserting
A ₂ is stacked on top of each other and the ends are sewn in the thickness direction of the futon. The other side of the intersection D ₂ is raised by making a cut E ₂ in the thickness direction of the futon in the horizontal gusset cloth piece 12 b ₂ , and inserts the end of the vertical gusset cloth piece 12 a ₂ around the cut E ₂ . It is sewn in the thickness direction of the futon and is formed by extending an insertion path B ₁ communicating with the insertion path B ₂ in the width direction to an end portion in the length direction of the futon. And the vertical gusset cloth piece 12a
The other edge 12a ₅ is also a horizontal gusset cloth piece 12b ₂
The other edge portions 12b ₅ are sewn together in the length direction, so that the side fabrics 11a and 11b are connected to each other (see Fig. 3A, Fig. 4A, Fig. 5A, Fig. 7). Figures to Figures 9).

In addition, in FIG. 1A, the vertical gusset cloth piece 12a ₂
and the horizontal partition cloth piece _12b1 located at the uppermost end are sewn together to form an intersection _D3 as shown in FIG. This intersection _D3 is made by making _{a cut E1 in} the vertical gusset cloth piece _12a2 along both sides of the seam S of the horizontal partition cloth piece 12b1, as shown in FIG.
The periphery of the notch E ₂ made in the horizontal partition cloth piece 12b ₁ is sewn to the periphery of this notch E ₁ in the thickness direction of the futon, and the insertion path B ₁ is formed so as to face the forehead F. ing. Of course, the other edges 12a ₅ of the upper and lower longitudinal gusset cloth pieces 12a ₂ and the other edges 12b ₅ of the upper and lower horizontal partition cloth pieces 12b ₁ are sewn together in the length direction.

Further, the intersection _D4 between the vertical partition cloth piece 12a ₁ and the horizontal gusset cloth piece 12b ₂ is sewn as shown in FIG.
This intersection D ₄ is the seam S of the horizontal gusset cloth piece 12b ₂
It is formed by sewing the periphery of the notch E ₁ (FIG. ₁₂ ) made along both sides of the horizontal gusset cloth piece 12b 2 to both sides of the horizontal gusset cloth piece 12b ₂ . The situation is the same as that shown in FIG. 3A. Of course, these other edges 12a ₅ and 12b ₅ are sewn together along their length.

Note that other intersections D are notched as described above.
The end of the vertical partition cloth piece 12a ₁ or the vertical gusset cloth piece 12a ₂ formed by E ₁ is placed on the side surface of the horizontal partition cloth piece 12b ₁ or the horizontal gusset cloth piece 12b ₂ in the thickness direction of the futon. To sew or form the forehead part F, connect both ends of the horizontal gusset cloth piece 12b ₂ to the vertical partition cloth piece 1.
The _{partitions A} are sewn on the sides of the futon in the thickness direction of the futon to prevent communication between the partition sections A.

In addition, each vertical and horizontal partition cloth 12a ₁ at the four corners,
The ends of 12b ₁ are connected as shown in Figure 1B.
They are overlapped in the plane direction and sewn to isolate each partition section A from the forehead section F. In addition, the surrounding forehead parts F are arranged as shown in Fig. 9 A and B,
One edge 15a ₁ of the cloth tape 15 is sewn to each of the four corners, and the other edges 15a ₂ of the cloth tape 15 are sewn to be separated from each other by sewing. As is clear from FIG. 9B, the cloth tape 15 at the four corner ends is in a folded state.

In the state where each partition cloth 12 is sewn as described above, as shown in FIGS. 7 to 10, the other edges 12a ₅ of the upper and lower vertical gusset cloth pieces 12a ₂ and the upper and lower horizontal gusset cloth pieces 12b ₂ The hose insertion paths B ₁ and B ₂ formed by sewing the other edge portions 12b ₅ are two in the width direction, upper and lower, and two in the direction of the upper and lower forehead portions F from these two. ing. As described above, openings C are provided on both sides of the insertion paths B ₁ and B ₂ to allow the feather pressure feeding hose to be exposed to each partition section A.

Next, a method for manufacturing the down comforter 10 having the above structure will be described.

First, as shown in FIG. 1A, one longitudinal edge 12a ₃ of the vertical partition cloth piece 12a ₁ and the vertical gusset cloth piece 12a ₂ is sewn to the side fabric 11a. Next, this side land 1
One longitudinal edge 12b ₃ of the horizontal partition cloth piece 12b ₁ and the horizontal gusset cloth piece 12b ₂ is sewn to 1a, and then cuts E ₁ , E ₂ are made at the positions shown in FIG. 1A and FIG. 11.
Put in. Similarly, each partition cloth piece 12a ₁ , 12b ₁ and each gusset cloth piece 12a ₂ ,
Sew 12b ₂ . Then, the intersection D is sewn as shown in FIG. 3(b), FIG. 4(b), FIG. 5(b), and FIG. 6. Also, the other edges 12a ₅ , 12b ₅ , _{15a 2} which are the free ends of each partition cloth piece 12a 1 , 12b 1 , each gusset cloth piece 12a ₂ , 12b ₂ and the cloth tape ₁₅ are aligned in the length direction. sew. The order follows 1 to 24 in FIG. Finally, cloth tape 15
and the ends of the vertical partition cloth 12a and the horizontal partition cloth 12b are sewn together in the thickness direction of the futon, and the periphery of the forehead F is sewn by hemming, etc., excluding the hose insertion opening 20.

Each of the partitions A on the futon side thus formed is filled with feathers, etc. in the following manner. That is, as shown in FIG. 10, the hose is inserted through the hose insertion port 20, and then the hose is inserted into the insertion path B ₁ ,
Insert a hose into B ₂ and force-feed a certain amount of feathers, etc. to each forehead F using compressed air. Also insertion path B ₁
A hose is made to face each partition A from the opening C, and feathers, etc. are force-fed into each partition A to fill the space. In this embodiment, the insertion path B ₁ at the intersection D ₂
and the insertion path _B2 are in communication with each other, so that the hose inserted from the hose insertion port 20 can be changed in direction as appropriate in the insertion path, as conceptually shown in FIG. There is an advantage that F can be filled with feathers. Finally, the hose insertion port 20 is closed to complete the down comforter 10.

When filling the partition section A with feathers, etc. as described above, the vertical gusseted cloth pieces 12a ₂ and the horizontal gusseted cloth pieces 12b ₂ each form a tunnel shape and serve as guides when inserting the hose. Easy to insert the hose. In addition, the partition section A is partitioned by two gusset cloth pieces 12a ₂ and 12b ₂ in the thickness direction of the futon, and the openings C located on both sides of the insertion path B ₂ are located in the partition section A. Since the hoses are spaced apart from each other in the same row, there is no possibility that feathers or the like will move from the hose insertion area to the adjacent partition A as in the conventional case. Also,
At each intersection D, the end of one partition cloth is sewn to the side surface of the other partition cloth and in the thickness direction of the futon, so communication between the partition sections A is prevented.
Furthermore, communication between the partition section A and the frame section F, and between the frame sections F is also prevented. Therefore, each partition section A and the forehead part _F1 are separated from each other, so to speak, like a closed room, and the feathers etc. filled inside do not move between each partition section A, and can be stored anywhere. Uniform bulk can be obtained and good heat retention can be maintained over a long period of time.

In the above embodiment, two insertion paths B are provided in the width direction of the futon, and one insertion path B is provided in the length direction of the futon. Two insertion paths B, one insertion path B may be provided in the width direction. In short, each partition section A
Any configuration is acceptable as long as the surrounding forehead area F can be filled with feathers, etc., but even in this case, each intersection D can be sewn like D ₁ , D ₂ , D ₃ , D ₄ . It is necessary to prevent the communication between each partition section A by using the following method.

"Effects of the Invention" In the down comforter of the present invention, the partition fabric at each intersection is fixed in the thickness direction of the comforter to prevent communication between the partition sections, so that feathers etc. between the partition sections during use are prevented. It is possible to almost completely eliminate the movement of the material, thereby achieving uniformity in bulk, and therefore maintaining a good heat retention state over a long period of time.
Further, the hose insertion path formed by blocking communication between the partitions serves as a guide when inserting the hose, making the insertion work easier and improving work efficiency. In addition, in the present invention, at the intersection where the partition cloths intersect, a notch is formed in the side surface of one of the intersecting partition cloths, and the end of the other partition cloth is attached to the periphery of the notch in the thickness direction of the futon. Since the insertion paths formed in the vertical and horizontal partition cloths are fixed and communicated with each other, each compartment and the frame F can be filled with feathers. Therefore, the work of re-inserting the hose one by one to fill with feathers can be omitted, which has the effect of improving the efficiency of feather filling and reducing costs.
