Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a futon and a method of manufacturing the same, and more specifically, the present invention relates to a futon and a method for manufacturing the same, and more specifically, a futon and a method for manufacturing the same. This invention relates to an improved futon in which a plurality of compartments are formed between the side fabric and the interlining by being attached alternately to the side fabric, and each of the compartments is filled with feathers or a feather-like filler, and a manufacturing method thereof.

(Prior Art and Problems to be Solved by the Invention) Conventionally, as a prior art similar to the present invention, there is, for example, a futon disclosed in Japanese Utility Model Publication No. 17-2007.

That is, as shown in FIG. 7, this futon is made by interposing an interlining material 2c between the front and back side fabrics 1c and 1d, and inserting the interlining material 2c alternately between the two side fabrics 1c and 1d at predetermined intervals. A large number of compartments 5 are formed in one direction (vertical direction) of the futon by sewing them with threads 14.

However, since the interior of this futon is partitioned in only one direction, there is a risk that the filling inside the futon may move within the compartment 5c when the futon is used or handled.
Overall, there was a problem that the filling inside the futon was uneven, resulting in an uneven state of the futon.

In particular, when the width of the compartment 5c increases, the feathers are more likely to move, and therefore, in this type of futon, the width of the compartment 5c has to be made narrower than necessary.

On the other hand, as an example of a futon in which the inside of the futon is divided both vertically and horizontally, there is a futon which is divided vertically and horizontally using a tape 15 coated with an adhesive 16, as disclosed in, for example, Japanese Patent Application Laid-Open No. 148912/1983.

In other words, this futon does not use an interlining like the above-mentioned futon, but is made up of only the front and back side fabrics and tape, and as shown in Figure 8A, two strips of adhesive are used. Tape 1 coated with agent 16
5 is folded in half as shown in FIG. be.

However, in such a futon, the intersections of the tapes 15 must be arranged closely, so the tips of the tapes 15 necessarily have an equilateral right-angled shape as shown in FIG. Therefore, it is extremely difficult to form each tape 15 into an equilateral right-angled shape at each intersection and to join the ends where the tapes intersect, and in reality, large gaps inevitably occur at the intersections of the tapes. Therefore, even though the chambers are divided by a large number of tapes, it is not possible to completely prevent the movement of fillers such as feathers between the divided chambers.

In particular, when handling the futon, such as putting it in and taking it out of the closet, more pressure is applied to the feather filling. Movement was becoming more likely.

Furthermore, in the above-mentioned futon, since the tapes 15 corresponding to the partition pieces are attached to the fabric on both sides in an upright state, there is less possibility that the side fabric will spread or bulge even when filled with feathers. Therefore, there was a problem that the duvet as a whole was difficult to bulk up, and the feel of the duvet could not be obtained.

Furthermore, as a result of the difficulty in creating bulk, there is a drawback that, for example, when such a down comforter is used on a bed or bed, there is a risk that the comforter may slip off during use. These drawbacks have been a factor that has hindered the spread of futons in foreign countries, where they are intended to be used as beds or beds.

Furthermore, in the futon as described above, since the tape 15 is provided in an upright state as described above,
When handling a futon side material that is not filled with feathers, the tape in that state becomes a hindrance, making it difficult to fold the futon side material into a flat state. As a result, it was difficult to pile up many futon sheets high and storage of the futon sides was inconvenient.

In addition, even if such an upright tape is filled with feathers, there will be no problem if the amount of feathers filled is large enough, but if the amount of feathers is small, the tape will become loose, making it difficult to use. There was a problem in that it sometimes gave the impression of a foreign body.

The present invention has been made to solve all of the above-mentioned problems, and by completely preventing the careless movement of fillers such as feathers within the futon, the unevenness of the filler within the futon can be prevented. It is an object of the present invention to provide a futon which can prevent the above-mentioned problems and which does not lose the necessary feel of a duvet due to an appropriate amount of bulk when being filled with down feathers.

(Means for Solving the Problems) In order to achieve such objects, the present invention has the following features:
This futon was created as a futon and its manufacturing method.
By interposing the interlining 2 between the side fabrics 1a and 1b alternately to the side fabrics 1b, a futon in which a plurality of compartments 5 are formed in one direction,
A, 1b and the core material 2 are interposed with a plurality of compartment pieces 3,... at predetermined intervals in the direction intersecting the compartment 5, and one end 3a of the compartment piece 3.
is attached to the core material 2 and the other end 3b is attached to the side fabrics 1a, 1b, respectively, thereby dividing the compartment 5 to form a plurality of filling chambers 12 for filling with feathers or feather-like fillings. Moreover, the dividing piece 3 is arranged so that the filling chamber 12 is filled with the feathers, etc., and the interlining 2 and the side fabrics 1a, 1
The reason is that it is attached diagonally to b.

In addition, the feature of the futon production method is that the filling material 2
A plurality of partition pieces 3 are attached at predetermined intervals to the inner fabric 2 by attaching one end 3a of the partition pieces 3 in the width direction of A large number of compartments 5 are formed between the side fabrics 1a, 1b and the interlining 2 by interposing the inner fabric 2 between the side fabrics 1a, 1b and alternately attaching them to the fabrics 1a, 1b on both sides, and then Each of the compartments 5,... is filled with feathers or a feather-like filler using a filling tool 13 that can be inserted into the compartment 5 through an opening 8 formed at one end of the compartment 5, and then the compartment pieces are 3
By attaching the other end 3b to the fabrics 1a and 1b on both sides, a futon is manufactured in which filling chambers 12 filled with a plurality of feathers or feather-like fillings are defined in the vertical and horizontal directions.

(Function) In other words, the side fabric 1 intersects with the compartment 5.
Both ends 3a and 3b of the partition piece 3 interposed between a and 1b and the inner interlining 2 are the inner interlining 2 or the side fabric 1
a, 1b, the compartment 5 is divided not only in one direction but also in the other direction, and as a result,
The filled feathers are closed in the filling chambers 12 divided vertically and horizontally, and never move over the partition walls of each filling chamber 12 to the other filling chambers 12.

In addition, since the partition piece 3 is provided so as to be oblique with respect to the interlining 2 and the side fabrics 1a, 1b when the filling chamber 12 is filled with feathers, when the filling chamber 12 is filled with feathers, the partition pieces 3 are provided so as to be oblique to the inner fabric 2 and the side fabrics 1a, 1b. This causes the futon to expand and bulge appropriately, which gives the entire futon its bulk.

Furthermore, as a result of the compartment pieces 3 being provided as described above, the compartment pieces 3 can be laid down in a natural state when handling futon fabrics that are not filled with feathers, and therefore the bag body for the futon fabric can be folded easily. It's easy to do. Therefore, it becomes possible to stack and store a large number of futon side sheets in a narrow space, and the storage becomes easy.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows a futon as an example, in which A is a plan view, B is a sectional view taken along the line A-A, C is a sectional view taken along the B-B line, and D is a sectional view taken along the C-C line of A. Ho is E's D-
A sectional view taken along the D line is shown.

In FIG. 1, 1a and 1b are front and back side fabrics made of polyamide synthetic fibers, and 2 is the side fabric 1.
The interlining made of non-woven fabric is interposed inside a and 1b, and is formed into a net shape with countless small holes 10, and its both ends 2a and 2b are interposed between the front and back side fabrics 1a and 1.
The two ends of b are sewn together by a sewing machine, and multiple locations in the longitudinal direction of the interlining 2 are alternately sewn on both sides to the front and back side fabrics 1a and 1b, respectively, as shown in Fig. 1 A and B. The entire area is heat-sealed via a heat-sealing tape 6.

3, ... are sections made of polyamide-based synthetic fibers, and as shown in FIG. The other ends 3b, . The position is the side fabric 1a via the double-sided heat fusion tape 6,
1b and the interlining 2 are heat-fused. A total of four pairs of partition pieces 3 are provided at predetermined intervals in the lateral direction of the side fabrics 1a and 1b, as shown by dotted lines in FIG. 1A. The partition chamber 5 is divided by such partition pieces 3 to form a filling chamber 1 for filling feathers.
2,... are formed. 4 is a feather as a filling material, which is filled into the plurality of filling chambers 12, . . . .

The dividing piece 3 is attached so as to be oblique to the interlining 2 and the side fabrics 1a and 1b when the filling chamber 12 is filled with the feathers and the like.

Next, a method for manufacturing a futon having the above-mentioned configuration will be explained.

First, the side fabrics 1a, 1b, the interlining 2, and four pairs of elongated compartment pieces 3 as described above are prepared, and as shown in FIG. 9, one longitudinal end 3a of each of the four pairs of compartment pieces 3 is prepared. ,... is the predetermined interval 4 in the transverse direction of the core material 2
The entire width of the core material 2 is heated and fused at the location. In addition, both ends of the partition piece 3 in the longitudinal direction are lined with the interlining 2.
It protrudes slightly from the top, and those parts are fused together.

Next, the interlining 2 with the partition pieces 3 attached in this manner is interposed between the side fabrics 1a and 1b, and the interlining 2 in the direction intersecting with the welding direction of the one end 3a of the partition pieces 3 is Double-sided thermal adhesive tape 6 is provided in advance alternately on both the front and back surfaces at a plurality of predetermined intervals, and a double-sided thermal adhesive tape 6 is also provided on the side facing the side fabrics 1a, 1b of the partition piece 3, and in that state. When a heating iron is pressed along the position where the double-sided heat-adhesive tape 6 is provided, a plurality of predetermined positions of the interlining 2 are exposed to the front and back side fabrics in the uninterposed part of the partition piece 3, as shown in FIG. 1a and 1b alternately through the double-sided heat-sealing tape 6, and the third
As shown in the figure, at the position where the partition piece 3 is interposed, the partition piece 3 and the interlining 2 are alternately attached to the side fabrics 1a and 1b through the two layers of double-sided heat-adhesive tapes 6, 6, respectively. They will be heat-fused at the same time in an integrated state.

By such heat fusion, a plurality of compartments 5, . . . are formed in the longitudinal direction of the futon. The side fabrics 1a, 1b and the interlining 2 are sewn in advance with a sewing machine at one end and both ends to form a closed side 7 at one end and an opening at the other end, as shown in Fig. 4. 8 will be formed.

Next, after forming the futon 11 in which a large number of compartments 5, . When the compartment 5 is moved to
The inside is filled with feathers 4. Further, in the same manner, each of the compartments 5, . . . is sequentially filled with feathers 4.

After all the compartments 5,... are filled with feathers 4 in this way, the other end 3 of each compartment 3,...
b, . It will be heat fused to 1a and 1b.

Then, all the partition pieces 3,...the other end 3b,...
are fixed to the side fabrics 1a, 1b, the compartments 5,... are divided by the compartment pieces 3,..., and there are five pieces each in the compartments 5,... as shown in Fig. 1C. The filling chambers 12, . . . are formed, and the openings 8 of the compartments 5, . . . are then closed to complete the production of the futon.

The futon manufactured in this way has a filling chamber 12 further formed in the compartment 5 by the compartment pieces 3 fixed at both ends 3a and 3b as described above, so that it cannot be filled. The filled feathers 4 are divided and closed within the filling chambers 12, .
The feathers 4 that have been partitioned and closed in the filling chamber 12 do not move over the partition wall of the filling chamber 12 to the side of the other filling chamber 12, so that the feathers 4 filled in the futon as a whole are uneven. There never is.

In addition, when filling the feathers, the compartment piece 3 is
Since the fabrics 1a, 1b on both sides are attached obliquely to the filling chambers 12, when the feathers 4 are filled in each filling chamber 12, the fabrics 1a, 1b on both sides
are oriented horizontally as shown in Figure 1 B, D, and H.
Not only does it cause a bulge, but it also spreads in the vertical direction, causing a bulge, as shown in Figure 1 (c), and spreads in both the vertical and horizontal directions, causing a bulge that tends to make the entire futon bulky.

In the above embodiment, the other end 3b of the partition piece 3 is attached to the side fabrics 1a, 1b by heat fusion using double-sided heat fusion tape 6 and an iron, but this attachment means is never used. The method is not limited to this, and for example, means such as welding using high frequency may be used, or means such as adhesion using an adhesive may be used. In short, the other end 3 of the partition piece 3
It is sufficient that b is attached to the side fabrics 1a and 1b, and the means of attachment does not matter.

Further, the means for attaching one end 3a of the partition piece 3 to the core material 2 is not limited to heat fusion as in the embodiment, but may be other attachment means, for example, by sewing. One end 3a may be attached to the interlining 2 side.

Further, the means for fixing the inner material 2 and the side fabrics 1a, 1b when forming the compartment 5 is not limited to heat fusing as in the embodiment, but may include welding or adhesion as described above. Alternatively, the interlining 2 may be attached to the side fabrics 1a, 1b by sewing.

Furthermore, in this embodiment, the one ends 3a, 3a of each pair of partition pieces 3, 3 are attached to both sides of the core material 2 at the same position, but the attachment position of the one end 3a of the divider pieces 3 is not necessarily in the middle. The arrangement is not limited to the same position on both sides of the interlining 2, but a plurality of partition pieces 3 may be provided spaced apart, for example, as shown in FIG. 6A.

Further, in this embodiment, a large number of partition pieces 3,... are all provided in one direction, but each partition piece 3,... may be provided in different directions, for example as shown in FIG. Gender is never a question.

Further, the number of partition pieces 3 is not limited to the four pairs in this embodiment, but may be three pairs as shown in FIG. 10, for example.
In short, it is sufficient if a plurality of them are provided. Therefore, filling chamber 1
The number of 2 does not matter. Furthermore, the number of compartments 5 does not matter, as long as a plurality of compartments 5 are provided.

In the above embodiment, after filling the entire area of the compartment 5 with feathers, the other end 3b of the compartment 3 is attached to the side fabric 1.
The filling chamber 12 is filled by heating and fusing the parts a and 1b.
Although the filling chamber 12 is filled with feathers at the same time as the filling chamber 12 is formed, the procedure for filling the feathers is not limited to this. For example, after filling the innermost part of the compartment 5 with feathers, the other end of the compartment 3 in that part Filling the filling chamber 1 one by one while filling the feathers by repeating such filling, fusing and closing the other end 3b of the partition piece 3.
2 may be formed. In this case, the partition pieces 3 are fused at appropriate locations in advance before filling with feathers, excluding the unfused portions for insertion of the filling tool 13,
Only the unfused portions may be fused after filling with feathers, and in this way the work can be performed more rationally.

Furthermore, as a filling procedure for feathers, all the filling chambers 12 may be completely partitioned in advance and then filled with feathers. In this case, by forming a cut for inserting the filling tool 13 at a predetermined position of the partition piece 3, it becomes possible to fill each filling chamber 12 with feathers using the filling tool 12.

Furthermore, the material of the side fabrics 1a and 1b is not limited to the polyamide synthetic fiber of the above embodiment, but may be other synthetic fibers, natural fibers, or a mixture of synthetic fibers and natural fibers. often,
The material is never questioned.

Similarly, the material of the partition piece 3 is by no means limited to polyamide synthetic fiber.

However, if synthetic fibers whose edges are fused and solidified by heating are used as the materials for the side fabrics 1a, 1b and the compartment pieces 3, the edges of the side fabrics 1a, 1b and the compartment pieces 3 will not fray. Therefore, there is an advantage that the feathers 4 do not become entangled with the frayed system. In particular, since the edges of the compartment pieces 3 inevitably come into contact with the feathers 4, among synthetic fibers with fused and coagulated edges as described above, non-woven fabrics or trichot fibers that do not cause the threads at the cut portions to fray are used. Using fabric is very effective.

Incidentally, since a nonwoven fabric is used as the material for the interlining 2 in this embodiment, there is an advantage that the interlining 2 does not get entangled with the feathers 4;
The materials are also not limited to the examples.

Furthermore, in this embodiment, the core material 2 has a large number of small holes 10.
Because it is formed into a net shape with a pore 4, the air permeability necessary for the feathers 4 can be maintained, and the compressed air forced into the compartment 5 escapes from the small holes, making it easy to fill the feathers 4. Although advantageous, a reticular formation is by no means a requirement.

In addition, the filling inside the futon is never filled with feathers 4 of this embodiment.
The filler is not limited to, for example, it may be made of cotton or the like, and the type of the filler does not matter.

Furthermore, the heating and fusing of the other end 3b of the interlining 2 and the partition piece 3 to the side fabrics 1a and 1b does not necessarily have to be carried out over the entire width in the longitudinal direction or the lateral direction as in the embodiment. For example, it may be done in a dotted manner.

In addition, the means for filling fillers such as feathers are not limited to the embodiments described above.

Note that the width of the interlining 2 (width in the lateral direction in FIG. 1) may be shorter than both edges of the side fabric. Further, a decorative fabric may be attached to the outside of the side fabric.

(Effects) As described above, the present invention provides a space for filling feathers by interposing an interlining between the front and back side fabrics and alternately attaching the interlining to the front and back side fabrics. A futon fabric bag is partitioned in one direction to form a chamber, and a plurality of partition pieces are interposed at desired intervals in a direction intersecting the partition between the side fabric and the interlining. By attaching both ends of the partition pieces to the center liner and side fabric, the futon fabric is divided vertically and horizontally.
The feathers inside the futon are divided into filling chambers that are divided vertically and horizontally. Therefore, when using or handling the futon, the feathers within the filling chamber can move freely within each filling chamber, but each filling chamber is The feathers never cross over the partition wall and move to other filling rooms, so there is no unevenness of the feathers in the entire futon as in the past, and even after long-term use, the feathers are This has resulted in a particularly remarkable effect in that a uniform state can be maintained within the interior.

In particular, as mentioned above, the interlining is attached to the side fabric and partitioned in one direction, and the partition pieces are attached to the interlining and side fabric and partitioned in the other direction, so at the intersection of the sections, The side fabric, the compartment piece, and the center liner are attached together, so there is a risk that a large gap will occur at the intersection, as in the conventional futon disclosed in JP-A No. 57-148912. Therefore, the effect of preventing the feathers from becoming uneven is significantly better than that of the conventional method.

In addition, since the unevenness of the feathers can be prevented by using the above-mentioned compartment pieces, the width of the compartment can be formed to a desired width, which is different from the conventional method.
It has the effect of not being restricted by the width of the compartment like the 2007 futon.

Moreover, since the partition pieces are attached obliquely to the inner liner and side fabric when filled with feathers, both sides of the fabric tend to spread or bulge when filled with feathers, thereby making the futon This results in an overall bulk, which has the effect of maintaining the required feel of the down comforter.

Furthermore, since the compartment pieces are attached in this way, there is no looseness when folding the compartment pieces, and the folding process can be easily performed, and even when not filled with feathers, it is easy to handle. This has the effect of making it easier. Also,
Even when the filling amount of feathers is small, the compartment pieces do not become bulky, so there is no feeling of foreign body during use.

Furthermore, in the futon manufacturing method of the present invention,
By interposing the interlining to which one end of a plurality of compartment pieces has been attached in advance between the front and back side fabrics, and then attaching the other end of the compartment pieces to the side fabric, a duvet filled with feathers can be filled in the filling chamber. Since the fabric is manufactured, it is possible to fabricate it by making and storing a large number of interlinings with partition pieces attached as described above in advance, and then attaching them to the front and back side fabrics according to the convenience of the work. Therefore, there is an effect that the work effort can be distributed arbitrarily.

Further, as a result, there is an advantage that various work-related conveniences can be achieved, such as being able to proceed with the work by attaching partition pieces such as those described above to the interlining even if the front and back side fabrics are not in stock.

Furthermore, the division of the futon in one direction is done by attaching the inner interlining at predetermined intervals to the front and back side fabrics, and the division of the inner interlining in the other direction is done by attaching the inner interlining to the front and back side fabrics. This is done by attaching both ends of the partition piece interposed between the ground to the inner fabric and the side fabric, so the intersection of the partitions in both the vertical and horizontal directions is made by integrating the side fabric, the partition piece, and the inner fabric. Therefore, unlike conventional futons in which the inside of the futon is divided vertically and horizontally only with partition tape, the tape tip is formed into an equilateral right angle shape at the intersection of the partitions, or the tip of that shape is There is no need to join the parts at each intersection, and there is an advantage that the vertical and horizontal divisions can be made quite easily by the above-mentioned interlining and division pieces.
