DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional quilt upper comforter filled with feathers and the like.

[0002]

2. Description of the Related Art As a conventional upper comforter of this type, for example, a wide gusset tape is run obliquely alternately on nylon taffeta, which is an inner fabric, with the side of the side fabric as a base, and the upper fabric is vertically cut from the point where they intersect each other. The quilt structure is formed into a three-dimensional quilt structure by forming a unit quilt structure consisting of a rectangular space filled with a filler such as feathers by sewing into a cone.

[0003]

However, in a conventional upper quilt of this type of three-dimensional quilt structure, a unit quilt structure or square having the same structure consisting of a square-shaped space overlaps vertically, and this is filled with feathers and the like. Is done. For this reason, when feathers and the like blown into the unit quilt structure warm and extend in the vertical direction, that is, in the height direction, they are mutually affected by the expansion of the other unit quilt structure adjacent in the vertical direction,
The mutual resistance of the elongation in the height direction increases, which causes the function of suppressing the swelling force to each other, and instead of filling a large amount of feathers and the like into the unit quilt structure, the swelling inherent in the feathers and the like is sufficient. It was not alive.

[0004] In addition, this type of conventional upper comforter has a structure such that when feathers or the like blown into a unit quilt structure extend in the up-down direction, that is, in the height direction due to the structure of the quilt or warm, the center quilt structure extends from four sides to the center side of the unit quilt structure. There is a problem that feathers and the like are gathered, the packing density of the feathers and the like at the four corners of the unit quilt structure is reduced, and the density of the feather is locally generated in the entire futon.

[0005] An object of the present invention is to make it possible to smoothly perform steps such as sewing and blowing of feathers and the like, as well as to increase the height of feathers and the like blown into a unit quilt structure, as in the case of a conventional three-dimensional quilt structure upper comforter. An object of the present invention is to provide an upper comforter having a three-dimensional quilt structure capable of increasing the swelling force by minimizing the restriction on the elongation in the vertical direction and increasing the swelling inherent in feathers or the like.

[0006]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a space between the upper side fabric and the inner fabric is partitioned by a gusset tape, and a filler such as feathers is filled in the partitioned space. An upper quilt portion having a unit quilt structure filled with, a space between the lower side fabric and the inner fabric is partitioned by gusset tape, and a unit quilt structure filled with a filler such as feather is provided in the partitioned space. A lower quilt portion, a middle quilt portion having a unit quilt structure in which a space between the upper inner fabric and the lower inner fabric was partitioned by gusset tape and a filler such as feather was filled in the partitioned space was provided. An upper comforter, wherein each unit quilt structure of the upper quilt portion and the lower quilt portion is formed of a quadrangular pyramid solid space, and the unit quilt structure of the middle quilt portion is formed of a rhombic solid space. It was on the adoption of the quilt to be.

In the invention of the second aspect, the middle quilt portion is such that the intersection of the diamond-shaped gusset tapes of the unit quilt structures adjacent to each other is substantially at the center of the unit quilt structure of the upper quilt portion and the lower quilt portion. It is arranged, and the intersection of the gusset tape of the lower quilt is located almost in the center of the upper quilt,
The upper comforter according to claim 1, wherein the intersection of the gusset tape of the upper quilt portion is located substantially at the center of the lower quilt portion.

According to the present invention, the above-described structure can smoothen steps such as sewing and blowing of feathers and the like, as well as feathers blown into a unit quilt tissue, similarly to the conventional upper quilt of a three-dimensional quilt structure. Thus, it is possible to provide a three-dimensional quilt structure upper comforter capable of increasing the swelling force by minimizing restrictions on elongation in the height direction and the like and sufficiently exhibiting the inherent swelling of feathers and the like.

FIG. 2 is a partial schematic view of the upper quilt section in FIG. FIG. 3 is a partial schematic view of the middle quilt section in FIG. FIG. 4 is a partial schematic view of the lower quilt section in FIG.

In the drawing, 1 is an upper side fabric, 2 is an upper inner fabric such as nylon taffeta, 3 is a lower side fabric, and 4 is a lower inner fabric such as nylon taffeta.

As shown in FIGS. 1 and 2, the upper side cloth 1
A unit quilt structure 6 partitioned by a gusset tape 5 is formed between the upper quilt portion 7 and the upper inner fabric 2. As shown in FIGS. 1 and 3, a unit quilt structure 9 partitioned by a gusset tape 8 is formed between the lower side fabric 3 and the lower inner fabric 4 to constitute the lower quilt portion 10. are doing. As shown in FIGS. 1 and 4, a unit quilt structure 12 partitioned by a gusset tape 11 is formed between the upper inner cloth 2 and the lower inner cloth 4, thereby forming a middle quilt portion 13. are doing.

The upper comforter of the present embodiment is shown in FIGS.
As shown in FIG. 4, each unit quilt structure 6, 9 of the upper quilt portion 7 and the lower quilt portion 10 is formed of a three-dimensional space of a quadrangular pyramid. The unit quilt structure 12 of the middle quilt portion 13 is formed of a diamond-shaped three-dimensional space.

As shown in FIGS. 1 to 4, the middle quilt portion 13 is formed such that the intersection 111 of the diamond-shaped gusset tapes 11 of the unit quilt structures 12 adjacent to each other is substantially at the center of the unit quilt structure 6 of the upper quilt portion 7. It is arranged to come. The lower quilt portion 10 is arranged such that the intersection 81 of the square gusset tapes 8 of the unit quilt structures 9 adjacent to each other is substantially at the center of the unit quilt structure 12 of the diamond-shaped middle quilt portion 13. In addition, the intersection of the gusset tape 81 of the lower quilt portion 10 is located substantially at the center of the upper quilt portion 7,
The intersection 51 of the gusset tape 5 of the upper quilt 7 is located substantially at the center of the lower quilt 10.

The upper comforter of the present embodiment is shown in FIGS.
As shown in FIG. 4, the gusset tape 11 partitioned into diamonds constituting the middle quilt portion 13 pulls the inner fabric 2 of the upper quilt portion 7 inward at the center portion 61 of the unit quilt structure 6, and the unit of the upper quilt portion 7 A three-dimensional space of a quadrangular pyramid having the central portion 61 of the quilt structure 6 as an apex is formed. Further, the gusset tape 1 divided into a rhombus constituting the middle quilt portion 13
1 pulls the inner fabric 4 of the lower quilt section 10 inward at the central portion 91 of the unit quilt structure 9,
It is configured as a three-dimensional space of a quadrangular pyramid having the central part 91 of the zero unit quilt structure 9 as the vertex. In addition, the central portion 61 and the central portion 91 of the upper quilt portion 7 and the lower quilt portion 10 constituting each vertex of the three-dimensional space of the quadrangular pyramid are shifted by 1/2 in the longitudinal direction and the width direction.

Accordingly, the upper comforter of the present embodiment fills the unit quilt structures 6, 12, and 9 of the upper quilt portion 7, the middle quilt portion 13, and the lower quilt portion 10 with fillers such as feathers, and then fills the respective quilt structures. In the unit quilt structures 6, 12, and 9, even if the fillers such as the feathers are swelled in the vertical direction, there is almost no adjacent filler that regulates the fillers.
The swelling force increases. In addition, each unit quilt organization 6, 1
Even if the packing density of the filler such as feathers is increased in the central part of 2, 9, the uniform filling density is obtained as a whole futon.

Further, since the futon of this embodiment has the above-mentioned structure, when the filler such as feathers contains air at the time of use or the like and tries to expand, each layer has a pyramid structure. Feathers and the like easily reach the apex of the quadrangular pyramid or the opposite surface by force. In addition, since the size and the shape of the quilt section of each layer, that is, the unit quilt structure, are different, the force at the time of swelling is dispersed, and the force at which the feathers and the like swell can be further utilized. Furthermore, since the large, small, and various large squares, ie, unit quilt structures, are regularly and alternately overlapped, the packing is less likely to be uneven, and a uniform packing density can be formed throughout the futon.

From the above, the upper comforter of the present embodiment is compared with a futon having a three-layer three-dimensional quilt structure even if the filling amount of feathers or the like in each square, that is, the unit quilt structure is small. Then, the feathers and the like can be sufficiently expanded by making use of the force for expanding the feathers and the like. In particular, the futon of the present embodiment has a three-dimensional quilt structure capable of promoting the expanding force when the filling is feathers and the feathers warm and expand during use.

FIGS. 5 to 9 are conceptual views showing the sewing positions of the gusset tape in the futon according to the present embodiment. FIG. 5 is a schematic bottom view (schematic back view) of the upper side fabric 1. FIG.
Is a schematic top view of the upper inner fabric 2. FIG. 7 is a schematic bottom view of the upper inner fabric 2. FIG. 8 is a schematic top view of the lower side fabric 3. FIG. 9 is a schematic bottom view of the lower side fabric 3. FIG. 10 is a schematic top view (schematic surface view) of the lower side fabric 3. In the futon according to the present embodiment, each gusset tape is sewn at such a sewing position to form a three-dimensional structure. In this embodiment, the gusset tape is sewn on the front and back surfaces of each fabric (excluding the front surfaces of the side fabrics 1 and 3). By sewing the gusset tapes of each fabric together, the three-dimensional space of the unit quilt structure can be obtained. Although it is formed, the present invention is not limited to this, and it is also possible to sew one side of each fabric and use this as a common gusset tape to form a three-dimensional space of a unit quilt structure.

In the futon of the above embodiment, although not shown in any of the above figures, as shown in the following FIGS. Is formed. FIG. 11 is a schematic cross-sectional view showing the upper layer quilt portion 7,
FIG. 12 is a schematic sectional view showing the middle quilt section 13, and FIG. 13 is a schematic sectional view showing the lower quilt section 10.

In the upper quilt section 7, as shown in FIG.
A filling port 71 is opened in each unit quilt structure 6 on one side of the futon, and a filling port 72 is opened therein. In addition, as shown in FIG.
Is opened in each unit quilt structure 6 on both sides of the futon, and a filling port 72 is opened inside. In the lower quilt section 10, as shown in FIG. 13, a filling port 101 is formed in each unit quilt structure 9 on one side of the futon, and a filling port 102 is formed therein.

As described above, in the case of manufacturing the futon of the present invention, for example, a method of sequentially filling the filler such as feathers from the unit quilt structure deepest from the filling port in the unit quilt structure in each layer quilt portion can be adopted. Then, a method of sequentially filling a filler such as feather for each layer quilt portion can be adopted. In addition, from the viewpoint of production, a method is preferable in which a filler such as feather is filled from the middle quilt portion, and then the upper or lower quilt portion is filled with a filler such as feather. For this reason, the futon manufacturing process of the present invention is not complicated as compared with the conventional quilt-structured futon, and can be easily manufactured.

In the unit quilt structure of the futon according to this embodiment, the upper quilt portion 7 is divided into squares at the center in the longitudinal direction of the futon, and both sides thereof have approximately half the area of the square at the center. , And the four corners are divided by approximately one-fourth the area of the square in the central area. However, the present invention is not limited to this. However, considering the size of the futon and the like, it is most preferable to configure the area ratio. Further, in the unit quilt structure of the middle quilt section 13, the area around the futon is 1% relative to the inner area of the futon.
/ 2, but the present invention is not limited to this. However, considering the size of the futon and the like, it is most preferable to configure the area ratio. Further, the lower quilt portions 10 all constitute a unit quilt structure with substantially the same area ratio, but this is not a limitation. In short, the area ratio of each unit quilt structure in each layer quilt portion can be set as appropriate in order to achieve the object of the present invention.

[0023]

Since the present invention is as described above, the steps of sewing, blowing feathers, etc. can be performed smoothly and can be blown into the unit quilt structure, similarly to the conventional upper quilt of the three-dimensional quilt structure. The swelling force can be increased by minimizing the restriction on the elongation of the feathers, etc. in the height direction, and the swelling inherent in the feathers can be sufficiently exhibited. It was possible to provide an upper comforter having a three-dimensional quilt structure.
