Description

Detailed Description of the Invention (Industrial Field of Application) The present invention improves the sewing and sewing method of a gusset fabric that forms an arbitrary partition space between a facing outer material and a lining material, and a feather supply opening. The present invention relates to a method for producing a down comforter that is easy to form, supply and fill with feathers, and eliminates unevenness.

(Prior technology) The best feathers used to fill up down comforters are the chest hair of waterfowl, but they are light and highly water repellent because they allow waterfowl to float on the water surface. He slipped inside, and one side ended up winning.

For this reason, it is already common practice to directly sew the outer material and the lining together after filling with feathers, or to provide a partition wall to prevent the filled feathers from shifting to one side.

However, with direct stitching, the amount of feathers decreases as you get closer to the quilting area, the feathers become harder, creating unevenness on the surface of the futon, and the feathers are exposed from the seams, making it difficult to retain heat. This impairs moisture absorption and also makes the appearance worse.

In addition, among those with partition walls, there are
There is No. 4, in which a gusset is sewn in a lattice pattern between the outer material and the lining to form a partition wall, the vertical gusset is cut at the intersection, and each side faces the continuous horizontal gusset in a T-shape. In addition, the facing part is not sewn to the horizontal gusset, and this acts as a feather supply port, but as a result, feathers can only be supplied from the side, especially into the partitioned space near the front and rear ends. Even when filling the space, it is necessary to manually insert the hose through several supply ports from the side to the space. However, there were some defects, such as the feathers opening slightly and the feathers sometimes moving.

(Problems to be Solved by the Invention) Therefore, the present invention proposes various uses for the gusset cloth connecting the front and lining to insert a supply tool such as a hose into the partitioned space to be filled in order to fill the feathers. It has a feather supply port that can be inserted from multiple directions, making it possible to close, save labor, and supply feathers efficiently.

The purpose of the present invention was to develop a down supply port that can be easily filled and further prevent the feathers once filled from being transferred to other partitioned spaces, and a method for manufacturing a down comforter using the same.

(Means for solving the problem) That is, the first invention of the present invention is to
In order to form a partitioned space, gussets 4j are sewn at appropriate relative positions using the seam allowance provided on one side of the gussets 4j, and then gussets 4j are sewn as far as possible from the seam allowance on the other opposing sides of i). A wide seam allowance is provided, appropriate areas are left unstitched, and the opening is sewn open (1), and both sides of the opening are sewn to form a feather supply port, and 1. a hose, etc. is supplied to the feather supply port. After inserting the ingredients in a push-in shape, the feathers are filled with atomized air, and then the peripheral edges of the outer material and the lining are sewn together to form an arbitrary partition space between the facing outer material and the lining. To form the gussets 11j, gussets 11j are sewn as appropriate using seam allowances provided on both sides of the gussets 11j, and cut at the intersection of the gussets 41 to form extensions on one side.1. Bend the cut end of the bosom along the other side, open the bent part without sewing, sew the root part to form a feather supply opening, connect it to the tip part to form a free end, and continue. A supply tool such as a hose is inserted into the partitioned space from the feather supply port to fill the feathers with atomized air, and then the peripheral edges of the outer material and the lining are sewn together. , is a combination of the first invention and the second invention, and in order to form an arbitrary partition space between the opposing outer material and lining material, each can be moved to its relative position as appropriate! ■ Sew j using the seam allowance provided on one side of this, and continue with the corresponding gusset! Provide a seam allowance as wide as possible than the seam allowance described in 111j on the opposing sides of 1j, and sew the appropriate parts unsewn so that they can be opened, and then sew both sides of the opening to form a feather supply opening. and further, cutting the intersecting gussets using the feather supply ports as intersections to form extension parts, and bending the cut ends along the crossed gussets,
The bent portion is opened without sewing and the root portion is sewn to form a feather supply port, and from this point the tip is formed as a free end, and then a hose, etc. is inserted from both the feather supply ports into the partition space. The feeder is inserted in a push-like manner to fill the feathers with atomized air, and then the outer material and 'AJ1! ! It is formed by suturing the periphery of the.

(Function) In the first invention, the present invention constituted by the means mentioned in the second paragraph is characterized in that, in the first invention, the wide seam allowance of the non-stitched part of the gusset futon which becomes the feather supply port is sewn on both sides and overlapped. Therefore, the seam allowance acts as a non-returning tab 1', and in the second seam 1y1, the tip of the extending portion is a free end, and the free end fills Ib'.
! Even if the charged feather tries to move backwards, its own pressure will push its tip against the other force's bulkhead, acting as an inertia valve, so once it is filled, the feather will never be able to move in the hand direction. becomes. Furthermore, in addition to being able to freely control the feeding direction, in addition to these mutual effects, in the second invention, by changing the direction of the mouth of the feeding tool, feathers can be continuously fed into knee or three partitioned spaces. II can be filled with
It is possible to provide a diverse supply of feathers.

(Example) In order to further clarify the gist of the invention, an example will be described using drawings.

FIG. 1 shows an embodiment of the first invention and the second invention, in which one side of the hem gusset iHi M is sewn to the front side %la and the lining 1b at opposing positions, respectively. , at this time, at the intersection C1, the gusset M3. M4 is cut with consideration given to providing an extended recessed part S, respectively, and the gussets $M 1 , which constitute the partition wall 11a,
M3. When sewing N4 to the front j1!41a or the lining 1b, it is not sewn to the gusset Ml and N2 that constitute the other partition wall 11a up to the intersection c1, which is the root.

Next, the town we faced! t5 M 1 and N2. N3 and N

Stitch at section N1 with matching stitches, and when you reach the appropriate location, change the stitching direction, cross the seam allowance Mn towards the end of the seam allowance Mn, and sew at 71 section N2. Then, by making 41 stitches in the appropriate dimension part, stitch the seam allowance Mn from the Fr seam allowance Mn end to the east at the seam part N2, changing the la [] direction and sewing the seam part Mn. Returning to the N1 line, the stitching is continued, and the pair of sewn portions N2 and N2 are overlapped, and the seam allowance Mn, which is the non-stitched portion, forms a feather supply port D1 that acts as an inflow valve.

In addition, the stitching by +iii marked sewing part N1 is performed up to the extension 1 recessed part S, and j. , interval 1; t
A non-sewn feather supply D2 is formed between the side surface of the partition wall 11a and the bent portion of the partition wall 12a. Feather supply [1D1 and D2 are normally closed due to the stiffness of the fibers as shown by the solid line, but when the supply AH of the hose cap is inserted in a push-in manner, they open as shown by the two-dot chain line [1] Therefore, when a feather (not shown in the figure) is supplied to the Y island in this state, and the appropriate amount of H, +- is filled and the supply tool H is removed, the state immediately returns to the solid line, and one feather does not move back. It disappears.

Further, the extending and recessed portion S of the free end shape 1 is pressed against the partition wall 11a by the internal pressure of the filled feathers, and acts as a "returning gun", thereby preventing the feathers from moving into the two sets.

Since FIG. 2 shows the first embodiment of the second invention, vertical bulkheads 17b and Ii? each formed of a lining 1b and a gusset itjM joined to a not-shown outer material, respectively, are shown in FIG. 1 Rear transverse bulkhead 1
2b, the vertical bulkhead 17b that contacts the front and rear horizontal bulkheads 12b in a T-shape at the intersection C2 is cut to provide an extension portion S, and is bent along the first front and rear horizontal bulkheads 12b to form a free form. In addition, in the front and rear transverse bulkheads 12b, the gussets M are not sewn together at the intersection C2 by the sewn part N1, and the gussets M are not sewn together in the transverse direction at right angles by the seam allowance Mn. The two partition spaces VI1 on the front side and the opposite side of the partition wall 17b are created by leaving the pair of sewn parts N2 sewn to

Furthermore, the feather supply port D4 can be replaced by simply changing the direction of the tip of the supply tool H, and the partition spaces II r, VIII
r.

Feathers can be supplied to each IXr, and the feather supply port D5 mainly supplies feathers to the partition space ■, but by simply changing the mouth direction of the supply tool H and replacing it, it can also supply feathers to the adjacent partition spaces Nr and Vlil. I can do it.

In addition, when the supply tool H is pulled out at the same time, the non-return valve acts as described above and automatically closes, so that the filled feathers cannot escape.

An example of the use of the feather supply port D4 is shown in the section A in FIG. 5, which will be described later.

Next, when filling one feather, insert a supply tool H such as a hose (not shown) from one of the feather supply ports D6, and then insert R) into either side of the diagonal wall L3b and the +iii rear transverse bulkhead 12b. The partitioning space is inserted into the feather supply port D3 provided at the intersection of After inserting it into V or VT (r or VT is fine), it blows air and fills it with feathers. When the predetermined amount of feathers has been filled, change the direction of the tip of the supply tool H by slightly pulling it back, and fill the adjacent partition space ■ or V. When the filling of the partition space is finished, the supply container H Further pull out and fill the previous partition space I[[, IV in the same manner as 177I.Furthermore, pull out the supply tool H and fill it into the partition spaces ■ and II. H is completely pulled out and the feather supply port D6 is sutured. This series of operations completes the filling of the four quarters of the comforter with feathers, and the down comforter A is completed by repeating this operation four times in total, once for each feather supply port D6.

Next, filling of the feathers is performed by supplying J1 (not shown). Insert the feather H from any of the feather supply ports D6, along either side of the side partition wall 13c, and from the feather supply port D4 provided at the intersection with the rear partition wall 12c of 1i71, into the partition spaces ■ and IX(r). Insert it into the holder (or a holder may be used) and fill it.

Next, pull the supply tool H slightly to remove it from the feather supply port D4, change the direction of the tip and insert it into the feather supply port D5, filling the partition space ■ and the other side (if starting from r, the sentence) ■. Then, after pulling the supply tool H to fill the partition space and 11 (r or vertical), it is pulled out from the feather supply port D6 and sewn. Then, fill the remaining partition spaces IX (r or cross) and II (r or father) from the feather supply port D6 on the other side and sew them to finish filling the - part of the futon with feathers, so repeat this operation. Repeat from the other side to complete down comforter B.

It should be noted that the present invention is not limited to the present embodiment, but may be applied to a partition wall that does not require a DI multi-shaped feather supply port, as long as the above-mentioned objective 1 effect of the present invention and the effects of the invention described below are achieved. Both sides of one wide piece of gusset fabric may be sewn to the outer material and the lining material without sewing the opposing gussets 4j, and the filling order etc. explained in FIGS. 4 and 5 may be changed as appropriate. Needless to say, these changes do not change the gist of the present invention.

(Effects of the Invention) As explained above in detail 4+1, in the first invention, the gusset fabric is sewn to the respective relative positions of the facing outer material and the lining material by seam allowances provided on the negative sides. When sewing while leaving a seam allowance as wide as possible on the other side, leave it unstitched and use it as a feather supply port so that an opening can be made at any point, and sew the seam allowance transversely on both sides of the opening. The seam allowances of the two sheets are always kept in a superposed state, and the feed tool is opened only when the feed tool is inserted between the seams in a push-in manner.Even if the feathers filled with the feed tool try to return, the 2 due to pressure etc.
This is to prevent the seam allowance side edges of the sheets from becoming more and more tightly polymerized and the feathers from returning. 45 is not cut at 91 at the crossing position, but is bent along the other gusset lIJ at the crossing point; δ, and its tip is an extended part with a free end form, and only the root is sewn at the crossing position. Since the feather supply [-] can be opened in the middle, it opens only when the supply tool is inserted in a push-in manner from the intersection X' position on the opposite side of the extended and recessed part. Even if the feathers filled with the feathers try to move back, the free end will become closer to the force distance of 1V due to the pressure etc., which absolutely prevents the feathers from moving back and can be formed on either the vertical or horizontal sides. Furthermore, the third invention is a combination of the second invention and the second invention described in , and is provided at the intersection, so it is applicable to all intersections, whether orthogonal or oblique.
Furthermore, by simply pulling the inserted feeding tool slightly and changing the direction of the tip, all the partitioned spaces defined by the intersection can be filled with feathers continuously, which is different from the conventional lattice shape. Unlike standard partition walls, it can be applied to any partition wall shape that does not cause discomfort to the sleeper and does not create gaps along the body.
Furthermore, as explained in the third invention, it is possible to fill several partitioned spaces with feathers at once, and the direction of the hill and the direction of the feather supply can be adjusted arbitrarily as explained in the second invention. It is extremely easy to fill with feathers because it can be set to
Since the time required for production can be shortened, production costs can also be reduced, and best of all, the filled feathers never shift to one side, so the heat retention and moisture absorption capabilities are maintained over a long period of time.

Furthermore, the shape of the partition wall can be arbitrarily determined so as to minimize the discomfort caused to the sleeper and the gap around the neck, so it must be said that this is an excellent invention that has many effects.
