Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion made of a bag made by stitching cloths filled with beads of relatively fine expanded polystyrene or the like. In the present specification, the cushion is not limited to a circular or square cushion used together with a so-called sofa, but the elasticity of the foam beads in a pillow, a pillow, a cushion, a bag-shaped sofa for 1 or 2 people, etc. It shall include all products packed with wood.

[0002]

2. Description of the Related Art Generally, depending on the size of a bag, a smaller particle size is often used, but 0.5 to 7 m.
A cushion made of a bag made by stitching stretchable cloths filled with expanded beads such as low-expanded polystyrene beads having a particle diameter of about m has attracted attention as a cushion giving a soft feel. There is a filling port on the cushion due to the need to close the filling port after filling the filling of the expanded beads, and there may be a case where it is necessary to refill the foaming beads, but the beads with a fine particle size are used. Therefore, as a mouth of a chuck (hereinafter also referred to as a zipper) provided in the bag so that the foam beads do not come out of the bag, it is known that double chucks in opposite directions close to each other are attached. ing.

[0003]

However, the reason why this is done is that the chuck cannot completely prevent the fine foam beads from coming out of the bag. The foamed beads used are fine and easily charged due to static electricity, and it is very difficult to put back or remove those that have come out of the bag, especially those that have accumulated at the end of the chuck. Therefore, the expanded beads that have leaked from the inner chuck have to remain in such a place, and there is always a large amount of expanded beads between the inner chuck and the outer chuck. Even if you approach a double chuck, it gradually leaks out of the bag. Also, the value as a cushion giving a soft feeling to the whole is considerably reduced by bringing the chucks close to each other and attaching them twice. Also,
The cost of the product increases by the amount of the chuck.

On the other hand, when the bag is filled with the foam beads and then the filling port is sewn and closed, an aesthetically undesirable portion is formed, or a troublesome hand-sew is required to keep the appearance. Furthermore, when replenishing the foam beads, it is necessary to unwind the neatly sewn portion.

[0005]

Means for Solving the Problems The present inventor has paid attention to the fact that the foam beads do not leak out from the seam, and on the other hand, the leak cannot be stopped by the chuck. Even if it is provided, it has been discovered that the above problem can be solved by sewn, or by sealing in various ways at a place sufficiently away from the chuck, instead of stopping the leakage of the foam beads with the chuck. The present invention has the following configurations.

1. A cushion comprising a foamed bead having a particle diameter of 7 mm or less packed inside and made by stitching cloth, the bag having a chuck opening for filling the foamed bead at an arbitrary position. Has a windsock-like fabric portion inside the chuck that begins at a position surrounding the chuck and ends with an open mouth, the open mouth at one end of the windsock-like fabric portion is the chuck. Of the windsock, and the mouth of the windsock-like fabric portion is closed by a closing means for preventing the foam beads from coming out of the bag when the cushion is used. cushion. Here, the closing means includes, for example, the following. B) Sew the mouth together. (B) It is preferable to tie the mouth with a string which is sewn tightly and softly, or a tape which is sewn, and in this case, a string loop or a belt loop is preferably provided. C) Clip the folds back, D) Make the windsock part elongated and tie it with confidence near the mouth. E) Make the mouth of the windsock-like cloth part smaller, attach a plastic mouth to the smaller mouth of the cloth, and attach a plastic lid to the plastic mouth. E) Closing with Velcro® which is attached facing the mouth or which is attached facing the folded back part and the fabric part which touches it twice or more. G) Attach the second chuck and close it.

2. A cushion comprising a foamed bead having a particle diameter of 7 mm or less packed inside and made by stitching cloth, the bag having a chuck opening for filling the foamed bead at an arbitrary position. Has a windsock-like fabric portion inside the chuck that begins at a position surrounding the chuck and ends with an open mouth, the open mouth at one end of the windsock-like fabric portion is the chuck. Cushion characterized in that it can be pulled out to the outside further, and that the mouth of the windsock-like fabric portion is sewn with fine stitches so that the foam beads do not come out of the bag when the cushion is used.

3. A sewn fabric is sewn together to form a bag that does not show the seam allowance, but at that time, the unsewn chuck sewn part is left in the sewn part of the bag and the sewn part of the chuck sewn part, or the fabric to which the chuck is attached An extra extension portion in a seam allowance portion for stitching with a fabric other than the extension portion so that the extension portion forms a windsock-like fabric portion from a position surrounding the chuck to an edge of the extension portion. And sew the chuck to the chuck sewn part (either order may be first), with the side of the bag to be the front side faced up, for example, in the state where the seam allowance of the bag is not exposed. Filling the inside of the bag with expanded beads having a particle size of 7 mm or less with the extended portion being pulled out to the outside of the bag from the chuck, and filling the inside of the bag with expanded beads. Afterwards, the opening end mouth of the windsock-like fabric portion formed by the extension is sewn so that the foam beads do not go out, or closed by any other closing means. .

4. A sewn cloth is sewn together to form a bag that does not show the seam allowance. At that time, prepare a zipper sewn part at an arbitrary position of the bag, the zipper sewn part, and a cloth including the zipper sewn part. Sew one end of the windsock-like cloth to a position surrounding the chuck sewing section selected from the group consisting of the sewn section of cloth other than the above and the surface of the cloth including the chuck sewing section (or After sewn, it may be sewn in a windsock shape), and the zipper may be sewn to the zipper sewn part (whichever comes first), with the side of the bag facing up, for example, on the bag. Filling the inside of the bag with foam beads having a particle size of 7 mm or less in a state where the seam allowance is not exposed and the other end, that is, the open end of the windsock-shaped cloth is pulled out to the outside of the bag from the chuck. Foaming And then closing the other end of the windsock-like fabric near the other end of the windsock-like fabric with any other closing means, provided that the windskin-like fabric is closed. The method of manufacturing a cushion, wherein the sewing of one end of the cushion and the sewing of the chuck include the case where the sewing is simultaneously performed at one time if applicable.

In the present specification, the "windsock-like cloth portion" is not limited to the one that is sewn so as to have a cylindrical shape like a windsock shape, and the start position of the windsock-like cloth portion is It includes those that can be sewn so that the windsink is flat as long as it is a position surrounding the chuck. Further, the "windsock-like shape" does not necessarily mean a tapered shape of the windsock, and the shape having the same size or the shape having a flared shape is also included. Further, the above-mentioned "position surrounding the chuck" and "position surrounding the chuck" do not have to be positions in the immediate vicinity of the chuck, but foam beads with the mouth facing upward are mentioned. It is preferable that almost all of the expanded beads can be accommodated when the same shape is completely filled and the position is maintained below that position, and it is meaningless at a position where most of the expanded beads cannot be accommodated. In addition, the cloth forming the cushion bag includes both non-stretchable cloth and stretchable cloth, but when stretchable cloth is used, an effect of giving a soft feeling can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Figure 1
FIG. 3 is a schematic view showing a cross section of a specific example of the cushion of the present invention. In the cushion 1 of this specific example, the seam allowance 3 of the chuck 2 has an extension portion 4, and the extension portion 4 is sewn together to form a windsock. The end of the windsock-shaped extension 4 forms a mouth 5, and near the mouth 5 there is a seam 6.

The cushion is manufactured as follows, for example. First, in the inside-out state, the cloth is sewn into a bag shape except for the chuck attachment portion, and the cloth of the extension portion 4 is folded back by the seam allowance 3 of the chuck 2. The chuck 2 is sewn on the seam allowance 3 in the chuck mounting portion of the folded back,
Next, the extension 4 is sewn in a windsock shape, or the extension 4 is first sewn in a windsock shape, and then the chuck 2 is sewn to the seam allowance 3. When the bag portion is turned upside down as shown in FIG. 1 so that the seam allowance 7 is on the inner side, the port 5 at the end of the windsock-shaped portion is pulled out of the chuck 2 and the foam bead supply port (not shown) is opened at the port 5. Put in the mouth of the bag formed by. If necessary, tightly wrap the mouth cloth around the feed opening to prevent splashing of the foam beads. When the filling of the foam beads is completed, the vicinity of the mouth 5 is sewn with a sewing machine while the vicinity of the mouth 5 is pulled out of the chuck 2. This sewing can be easily performed with the mouth 5 pinched from above.

FIG. 2 is a schematic sectional view showing another embodiment of the cushion of the present invention. In these specific examples, one end of the cloth 24 in a windsock shape is sewn around the chuck 22 so as to surround the chuck 22.

In this cushion 21, instead of stitching the extension 4 of FIG. 1 in a windsock shape, the chuck 2 surrounds the chuck 22 with one end of a windsock-shaped cloth 24.
It can be manufactured in the same manner as in the specific example of FIG. 1 except that it is sewn to 2. The example shown in FIG. 7 is similar to that of FIG. 2, but the windskin-like fabric and the chuck are sewn together to make manufacturing more efficient.

The embodiment shown in FIGS. 6 and 8 is also the same as that shown in FIG. 2 except that one end of the windsock-like fabric is attached at a different position.
And it can be manufactured in the same manner as the specific example of FIG.

FIG. 4 is an explanatory view showing that various forms can be used as means for closing the mouth of the open end of the windsock-shaped fabric portion, and FIG. 10 is a schematic view showing various shapes such as a pillow, a backrest, and an article for buttocks.

FIG. 6 shows a state in which the left side is turned up during manufacturing and a state in which the right side is exposed when the windsock-like cloth is sewn at the same time as the sewn portion of the cloth to which the chuck is attached and the other cloth. It is a schematic diagram for explaining.

FIG. 7 shows a state in which the windsock-like cloth is sewn to the chuck mounting cloth at the same time when the chuck is sewn to the cloth to be attached to the chuck. It is a schematic diagram for explaining.

FIG. 8 is a schematic diagram for explaining a state in which the windsock-like cloth is sewn on the cloth to which the chuck is to be attached, and the right side is turned upside down and the right side is shown.

FIG. 9 shows a case where a windsock-like cloth is sewn to a cloth to which a chuck is attached, and a second chuck is sewn to the opening end of the windsock-like cloth to form a closing means. 6 is a schematic diagram illustrating a state of turning over the left side during manufacturing and a state of showing the right side in the case. In the case of the specific example of FIG. 9, it is not close like the conventional double chuck,
Moreover, the difference is that the internal chuck can be pulled out to the outside of the external chuck, which solves the problem of difficulty in removing the expanded beads that accumulate between the chuck and the effect that it is easy to fill the expanded beads. is doing.

FIG. 10 shows a case where a windsock-like cloth is sewn to a cloth to which a chuck is attached, and a magic tape (registered trademark) is sewn to the opening end of the windsock-like cloth as a closing means. 2 is a schematic view for explaining the left-side upside-down state during manufacturing and the right side-out state. The Velcro® can be folded to make the closure more complete.

[0023]

[Effect] Completely prevent leakage of fine foam beads from the bag, which is a drawback of a cushion in which fine foam beads are packed as a pad in a stretchable cloth bag having a soft and unique touch and feel.

When the mouth is sewn together as a closing means, since it has a sewn mouth in the chuck, that is, it does not come out to the surface, it is possible to refill the foam beads by unsealing the mouth. After refilling, the stitches can be re-sewn together to prevent leakage, and since the seam of the refilling port is hidden by the zipper, there is no aesthetically unpleasant appearance that the seam of the mouth is visible. Further, since the chuck is single, the cost for one chuck is naturally low.

Further, in this case, as compared with the case of using the double chucks that are close to each other, it is more excellent in the function of preventing leakage and in that the chuck portion does not adversely affect the flexibility of the cushion.

Not only when the closing means is sewn, but the seam of the sewn mouth portion in the chuck and other closing means are inside the chuck and there is room in the cloth, so that pressure is applied to the cushion. The force received from the padding when applied is not directly exerted by the chuck on the seams or other closure means. Therefore, the force for opening the seam and other closing means is not applied thereby, and durability is provided by preventing leakage.

Rather than manufacturing a cushion having dual chucks in close proximity to each other, the manufacture of the cushion of the present invention may be simpler in structure and may be less costly to manufacture.

Also in the filling operation of the foam beads during manufacturing, the cloth in the cylindrical mouth portion can be brought into close contact with the supply port of the foam beads, and the cloth is placed outside the bag farther from the foam beads than the chuck. Because it can be sewn together with, it is much easier than with a chuck.

The chuck is closed to hide the cylindrical cloth, not to prevent leakage near the top of the expanded beads in the bag, and the beads are closed even when the second chuck is closed. Since it is closed at a position away from, it is not necessary to pay particular attention to the chuck when manufacturing or when refilling the expanded beads, when the expanded beads are fully filled in the bag.
