Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a down comforter.

[0002]

[Prior art]

 Traditionally, feather futon has been used mainly as a high-grade comforter because it is lightweight and has extremely good heat retention. However, because it is lightweight, it tends to lack stability, and the degree of airtightness around the futon is low on the floor surface. There was a problem in that the warmth-keeping performance inherent in the beckoning feather was not utilized.

[0003]

[Problems to be solved by the device]

 In consideration of the above-mentioned points of the conventional down futon, the present inventor has achieved a comprehensive structure by preventing the invasion of outside air and the accompanying dissipation of heat inside the futon due to its high stability and high degree of closeness to the floor surface. The purpose was to obtain a down comforter with excellent cost performance while improving the heat retention performance.

[0004]

[Means for Solving the Problems]

 The outer material and the lining are integrated by interposing a gusset of an appropriate height, and a plurality of small compartments adjacent to each other via the gusset are formed between the outer material and the lining, and the small compartment is provided in the small compartment. The packing density is such that the packing such as feathers is enclosed, and the packing density of each small compartment on the both sides of the futon is relatively higher than the packing density of the packing in the center of the other futon. . Feathers were enclosed in the small compartments on both sides of the futon, and downs were enclosed in the other small compartments in the center of the futon.

[0005]

[Embodiment of device]

 Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the down comforter is made by binding the outer lining 1 and the lining 2 together at the outer peripheral edges thereof, and integrally forming the quilts 31 and 32 of an appropriate height in which the intermediate portion is oriented in a lattice-like manner with respect to the background. A plurality of small compartments 41 and 42 are formed inside the futon.

Of the plurality of small compartments 41 and 42, the small compartments 41 on both side edges of the futon are arranged in the central compartment of the futon due to the arrangement of the gusset 31 oriented in the futon longitudinal direction. Compared with this, the width A is narrower, and therefore the inner volume is smaller. Feather F is enclosed in each small compartment 41 on both sides of the futon, and down D is enclosed in each small compartment 42 in the center of the futon. Each filling amount is set so that the density is relatively higher than the filling density of the down D of the small compartment 42 of the futon central portion.

FIG. 2 shows an embodiment of the present invention, in which 50 g of feather F is filled in each small compartment 41 on both side edges, and 80 g of down D is filled in each small compartment 42 in the central portion. Since the compartment 41 has 10 compartments and the small compartment 42 has 15 compartments, the total weight (filled) of each of them is feather SF = 0.5 kg and down SD = 1.2 kg. A simple comparison of the above filling amounts shows that the filling amount of the down D enclosed in the small compartment 42 on the central side is large, but the width A of the small compartment 41 is about one half of the width B of the small compartment 42, which is substantially the same. The content density is less than that, so the packing density is a little over 1.2 times.

FIG. 3 shows an example in which the down comforter is used as a down blanket. The small compartments 41 on both side edges are filled with 40 g of feathers F and the central compartment 42 is filled with 40 g of down D. . The total filling weight of each is feather SF = 0.4 kg, down SD = 0.6 kg, and the packing density of each small compartment 41 on both side edges is slightly more than double that of the central small compartment 42.

When enclosing the down D and the feather F in each of the small compartments 41, 42, from the one end of the gauze cloth 31, the tubular shape of the dorsal cloth 31 in the longitudinal direction double-folded into a tubular shape. This is done by inserting a feather feeding pipe (not shown) into the section, and inserting the tip of the feather feeding pipe (not shown) into each of the small compartments 41, 42 from the slit 33 opened in each of the small compartments 41, 42. After filling and enclosing the feather F, the feather feeding pipe is removed from the balustrade 31, and then one end of the balustrade 31 is closed. It should be noted that, like the cloth for cloth 32, the cloth for cloth 31 may be formed of one piece of cloth, and the down D and the feather F may be enclosed in the small compartments 41, 42 at the time of sewing.

As shown in FIG. 4, the down comforter configured as described above has a high packing density of the feathers F 2 as shown in FIG. 4, and is therefore a small compartment 41 on both side edges which is set as a heavy down comforter. Due to the gravity acting on the floor, the airtightness of the floor (futon) around the futon is high. Furthermore, the hem of the comforter does not float easily when rolled over, and even if it is lifted, it sinks well due to its own weight, so the outside air invades from the area around the comforter and the heat dissipated inside it. Can be prevented.

Further, while obtaining the above-mentioned effects, each small compartment 42 in the central portion of the futon which is in contact with the body is filled with the down D which is bulky, has a high heat retaining effect and is soft to the touch, and thus, like the conventional down comforter. In addition to having a good feeling in use, the feathers F, which are cheaper than the down D, are sealed in the small compartments 41 on both side edges, which have a high packing density and therefore a large total filling weight, so that the entire futon can be used. The cost can be reduced to the same level as or lower than the conventional cost.

Further, the packing densities of the feathers F and the down D are different between the small compartments 41 and 42, but the air content of the down D is larger and therefore the specific volume is larger, so that the apparent thickness is almost the same. Therefore, the appearance of the futon is as if the filling was uniformly filled in all the compartments, and it does not mean that only the small compartments 41 on both side edges having a high packing density swell.

In the above embodiment, the feather F is enclosed in the small compartments 41 on both side edges and the down D is enclosed in the central compartment 42, respectively. It is also possible to mix other materials that are commonly used as futon cotton. Further, in the above-described embodiment, the case where the goose cloths 31 and 32 are oriented in a lattice shape has been shown, but the present invention is not limited to this, and the case where the goose cloth is oriented in a slanted lattice shape or a lattice with that. It can be applied within the scope of the present invention to a combination of a striped quilt, and further to a down comforter having two layers of upper and lower layers with an interlining in the middle layer of the front and back sides. Is added.

[Effect of device]

 As described above, the down comforter of the present invention integrates the outer material and the lining by interposing a gusset of an appropriate height, and a plurality of materials which are adjacent to each other with the gusset between the outer material and the lining. And a filling material such as feathers is enclosed in the small compartments, and the packing density of the packing material of each small compartment on the both side edges of the futon is the packing density of the other central portion of the futon. Since it is made relatively higher than the filling density of the futon, the specific weight of both sides of the futon becomes relatively larger than that of the central part, which is excellent in stability and the degree of sealing of the futon periphery to the floor surface is high. It is improved and the bottom of the futon does not easily lift up even when it is rolled over, and even if it is lifted, it will sink well due to its own weight, preventing outside air from entering the perimeter of the futon and consequent dissipation of heat inside the futon. Good heat retention performance can be obtained.

[0015] Furthermore, since the feathers are enclosed in the small compartments on the both sides of the futon and the down compartments are enclosed in the other small compartments in the central portion of the futon, the stability and the sealing of the futon peripheral area are improved. The synergistic effect of the effect and the down of the central part of the duvet provides extremely good heat retention performance, and the feathers, which are cheaper than the down, are enclosed on both sides to impair the texture of the duvet. The cost of the futon as a whole can be kept low.
