DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to feather futons.

[0002]

2. Description of the Related Art Conventionally, a feather futon divides a space inside a futon formed between a surface material and a lining into a plurality of small sections, uniformly fills the feathers in each of the small compartments, and moves and moves the down. Bias is prevented. As a method of partitioning the space inside the futon, a gore cloth of an appropriate height arranged in a lattice between the surface material and the lining of the futon is interposed, and a plurality of small compartments partitioned by the gore cloth are formed, There is known a three-dimensional quilt feather futon in which the small compartments are filled and filled with feathers.

[0003] As means for filling feathers into the down futon of this three-dimensional quilt, one of the gore cloths of either process is made double, and a passage through which a feather filling pipe can be inserted is formed between the gore cloths. After the small compartments adjacent to each other are shifted so that they do not directly communicate with each other, a small opening such as a slit is provided, and the outlet of the tip of the feather filling pipe inserted into the passage is sequentially inserted into each small compartment to fill the feathers. There is a method of closing the entrance of the passage. According to this method, feathers can be filled after the sewing of the bedding is completed except for the entrance of the passage, and workability is significantly improved as compared with the method in which sewing and filling of the feathers are performed in parallel.

[0004] The above-mentioned feather futon is generally mixed with small feathers at an appropriate ratio to the down for the purpose of suppressing the cost of expensive down and adding bulkiness. The height of the gore cloth is about 5 to 6 cm. Sufficient dimensions can also be ensured for the slit formed in the gore cloth and the passage for inserting the feather filling pipe.

[0005] On the other hand, an eider down (eid down) in which the feathers are finer than a normal down and have a strong tendency to coagulate.
In the case of (er down), the heat retention of the down itself and the drape of the bedding filled with the down are excellent, but it is not suitable for mixing small feather. For this reason, it is difficult to form it on a bulky futon. Conventionally, it has been common to form a thin futon by a normal quilting technique without using a gore cloth for an eiderdown feather. However, in normal quilting, the heat insulation of the sewn part is necessarily reduced, so that the heat insulation of the entire futon is spoiled, and it is desirable to use a three-dimensional quilt like a normal down. It is rare. However, since the feather futon of the Eiderdown cannot be made bulky for the above-mentioned reason, when forming a three-dimensional quilt, the height of the gore cloth is 3 cm.
I have to stop to the extent. For this reason, with such a low gore cloth, a sufficient dimension cannot be secured in the passage or slit for inserting the feather filling pipe, and there is a problem that it is difficult to apply the feather filling method based on them.

[0006]

SUMMARY OF THE INVENTION In view of these problems of the prior art, the present invention has a simple structure and can form a feather-filled pipe insertion path wider than the height of a gore cloth. The object of the present invention is to obtain a feather futon which has good workability for filling feathers and hardly causes movement of feathers.

[0007]

A plurality of small compartments partitioned by the gore cloth are formed by interposing a gore cloth of an appropriate height arranged in a grid between the outer material and the lining, and the small compartment room is formed. In a feather futon filled with feathers, stretchable yarns with or without stretch are knitted or woven with stretchable yarns on a part of the gore cloth facing each small section Provide a valve cloth made of a stretchable sheet material having an elastomer layer formed on at least one surface of the base cloth, the valve cloth itself,
Alternatively, a slit is formed in a joint portion between two divided valve cloths, or a valve cloth and a gore cloth, or a valve cloth and a surface material, or a joint part between a valve cloth and a lining, and an adjacent small compartment is formed through the slit. They were communicated with each other, so that a feather filling pipe could be inserted into each small compartment.

[0008]

1 to 3 show an embodiment of a down comforter according to the present invention, which will be described below.

In the figure, the down comforter according to the present invention is provided with gore cloths 3 and 4 arranged in a lattice in the longitudinal direction and width direction between the outer material 1 and the lining 2, and the gore cloth 3 is provided inside the bedding. , 4, a plurality of small compartments 5, 5 ...
Are formed, and the feathers 6 in the small compartment 5 are filled.

Each of the three rows of gore cloths 3 oriented in the longitudinal direction of the futon extends over the entire length in the longitudinal direction of the futon.
It consists of a strip of cloth. On the other hand, the gore cloth 4 oriented in the width of the futon which intersects with the gore cloth 3 is constituted by a separate band-shaped cloth piece for each small section 5, and in the illustrated example, four band-shaped cloth pieces are arranged in one row. It is composed of cloth pieces.

The center gore cloth 3a of the crossing portions of the gore cloth 4 in the width direction and the three rows of gore cloths 3 in the longitudinal direction.
At the intersection A between the gore cloth 4 and the gore cloth 4, the gore cloths 3 a and 4 are directly sewn or sewn by other means, but at the intersection B between the gore cloths 3 b and 3 b and the gore cloth 4 on both sides. The valve cloth 4 made of an elastic sheet material is attached to the ends 40, 40 of the gore cloth 4.
1 are sewn, the gore cloths 4 and 4 are connected by the valve cloth 41, and a slit 42 formed in the center of the valve cloth 41 is formed.
A crossing portion B is formed by penetrating through the gore cloth 3b, and the longitudinal direction (gore cloth 3
are adjacent to each other in the direction (b direction).

That is, the valve cloth 41 has upper and lower edge portions 41.
In a and 41b, the gore cloth 4 is sewn together with the gore cloth 4 together with the gore cloth 4 to form a part of the gore cloth 4; Has become.

As the stretchable sheet material used for the valve cloth 41, a stretchy yarn such as nylon, polyester or the like, a stretch-processed yarn (bulk-processed yarn), a polyurethane elastic yarn or a covering yarn thereof is knitted or formed. Stretch knitted fabric, base fabric made of stretchable woven fabric,
Alternatively, a yarn having no elasticity other than the stretched yarn and the polyurethane elastic yarn is knitted, and a layer of an elastomer such as synthetic rubber or natural rubber is formed on at least one surface of the elastic base fabric by a knitting structure. Thing, for example, heat-sealing a thin sheet of polyurethane rubber on a stretchable base fabric,
Alternatively, a stretchable coated cloth or a laminated cloth formed by laminating by means of adhesion or the like or applying a solution-like polyurethane rubber is preferable. These have the advantage that the required strength is ensured by the stretchable base fabric and that they are not easily torn when filling feathers, etc., and the elastomer layer is made of an elastomer such as polyurethane rubber whose form is stable and the eyes of the base fabric are coated or laminated. The feathers do not clog or pass through the eyes of the expanded base cloth.

The futon was sewn with outer material 1, lining 2, gore cloth 3, 4 and a valve cloth 41 made of an elastic sheet material, and the insertion opening 7 of the feather filling pipe 8 shown in FIG. 2 was removed. After the peripheral edge of the bedding is sewn, the feather filling pipe 8 is inserted through the insertion port 7 to fill each small compartment 5 with the feather 6.

That is, the feather filling pipe 8 is inserted into the insertion port 7 at the end.
, The tip of the feather filling pipe 8 is automatically inserted into each slit 42 and successively penetrates the adjacent small compartment 5. At this time, since one side of each slit 42 is formed of the valve cloth 41 made of a stretchable sheet material, it can be easily expanded and the feather filling pipe 8 can be inserted very easily.

In particular, the elastic deformation of the valve cloth 41 allows the slit 42 to be widened wider than the size of the slit 42, and the gore cloth 4 (3) facing the slit 42 as well as the gore cloth 4.
Also in b), no excessive force or deformation is applied when the feather filling pipe 8 is inserted, so that these sewn portions are not damaged. Therefore, the height of the gores 3 and 4 is 2-3 cm.
Even with a three-dimensional quilt for eiderdown or a thin three-dimensional quilt such as a summer futon, the work of filling feathers can be performed easily and reliably. Further, after the feather filling pipe 8 is pulled out, the slit 42 is securely closed by the elastic recovery of the valve cloth 41, and the movement of the feather can be surely prevented.

The valve cloth 41 is made of an elastic sheet material in which an elastomer layer is formed only on one surface of an elastic base cloth, and the surface on which the elastomer layer is formed is positioned with respect to the insertion direction of the feather filling pipe 8. By arranging the valve cloth 41 so as to be on the back side, when the feather filling pipe 8 is inserted, the tip of the pipe 8 comes into contact with the elastic base cloth surface of the valve cloth 41 which is more slippery than the elastomer surface, The pipe 8 is easily inserted, and when the feather-filled pipe 8 is removed from the small compartment 5 after the feathers are filled, the seal of the slit 42 is further improved by the close contact of the elastomer surface with the pipe 8. Become good. In filling the feathers, first, the feather filling pipe 8 is inserted from the insertion port 7 to the innermost small compartment 5, and the innermost small compartment 5 is filled with feathers. While the small compartments 5, 5,... On the near side are successively filled with feathers, after all the small compartments 5 are filled with feathers, the insertion port 7 is closed.

The feather futon constructed as described above has a slit 42 formed by a valve cloth 41 made of an elastic sheet material, so that the feather filling operation can be performed easily and reliably as described above. When the futon is folded by the elasticity of 41, not only is the slit 42 difficult to open even in cases such as when the feather intervenes in the slit 42, but the feathers are caught by the inherent stickiness of the elastomer, and There is also an effect that movement of feathers is prevented.

Further, in the down comforter of the above embodiment, the longitudinal gore cloth 3 is constituted by a single band-shaped valve cloth extending over the whole of the bedding, and the gore cloth 3 and the width gore cloth 4 Since the slit 42 and the valve cloth 41 forming the slit 42 are disposed at the intersection B, the valve cloth 41 and the insertion port 7 are located in the small compartments 5, 5 located on both sides of the gore cloth 3. The location where the valve cloth 41 and the insertion port 7 are provided is minimized, and the construction of the gore cloths 3 and 4 is also simple.

In the above embodiment, the slit 42 is formed at the center of one valve cloth 41. However, the valve cloth 41 is divided into two pieces, and the slit 42 is formed at the joint portion. You may.

The valve cloth 41 and the slit 42 may be provided only on one side of one longitudinal gore cloth 3 (3b). Further, regardless of the longitudinal gore cloth 3,
A valve cloth 41 may be provided at an intermediate portion of the gore cloth 4, and the slit 42 may be formed in an appropriate direction such as a thickness direction, a horizontal direction, and an oblique direction. In that case, it is preferable that the valve cloth 41 or the gore cloth 4 forming both side portions of the slit overlap each other. Further, in the down comforter of the embodiment, the valve cloth 41 is extended toward the gore cloth 3 and bent along the gore cloth 3, and a slit is formed at the overlapping portion between the bent portion and the gore cloth 3. You may do it.

Further, a valve cloth and a slit made of a stretchable sheet material can be provided in the longitudinal gore cloth 3 to insert the feather filling pipe 8 in the width direction.
May be arranged in a diagonal lattice or a hexagonal lattice. It is also possible within the scope of the present invention to integrate the outer material 1, the lining 2, the gore cloth 3, 4 and the valve cloth 41 by means other than sewing, such as heat sealing or bonding.

[0023]

As described above, the down comforter of the present invention has a plurality of small compartments partitioned by the gore cloth by interposing a gore cloth of an appropriate height arranged in a lattice between the outer material and the lining. In the feather futon formed and filled with feathers in the small compartment, knit a yarn with or without stretch on a part of the gore cloth facing each small compartment, or A valve cloth made of a stretchable sheet material in which an elastomer layer is formed on at least one surface of a stretchable base cloth formed by weaving a thread having the valve cloth, the valve cloth itself, or a joint portion between two divided valve cloths, or a valve A slit is formed at the joint between the cloth and gore cloth, the valve cloth and the outer material, or the joint between the valve cloth and the lining, the adjacent small compartments communicate with each other through the slits, and a feather filling pipe is inserted into each small compartment. Simple structure and easy manufacturing There, and can widely spreading the slit as compared to the dimensions of the slit by an elastic deformation of the valve cloth,
Even if it is a thin three-dimensional quilt such as a three-dimensional quilt for the Eiderdown or a summer futon, the feather filling operation can be performed easily and reliably, and after the feathers are filled, the movement of the feathers between the small compartments hardly occurs. An effect in both productivity and practicality can be expected.

In particular, the above-mentioned valve cloth has an advantage that the required strength is ensured by the elastic base cloth and the valve cloth is hardly damaged at the time of filling the feathers, etc., and the shape of the base cloth is stabilized by the elastomer layer, so that Is closed, the feathers do not clog or pass through the eyes of the expanded base cloth, and even if feathers intervene in the slits, the feathers are trapped by the stickiness of the elastomer. Movement of the feather through the slit is prevented.
