Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a method for manufacturing a futon, more specifically, a middle interlining is interposed between front and back side fabrics, and predetermined positions of the middle interlining are set on the front and back sides, respectively. The present invention mainly relates to a method of manufacturing a duvet or the like, in which a plurality of compartments are formed between the side cloth and the center core by alternately mounting the side cloth and the compartments are filled with a filling material such as feathers.

(Prior Art) Generally, as shown in FIG. 12 (a), a conventional futon of this type has a center interlining 2c interposed between front and back laterals 1c and 1d.
c is alternately sewn on both sides 1c and 1d with thread 17 at predetermined intervals to form a large number of compartments 5c ,.
Side land in the direction intersecting the compartment 5c as shown in Fig. 12 (b)
A plurality of partition pieces 3c, ... Are preliminarily interposed between 1c, 1d and the central interlining 2c, and one end 3d thereof is sewn to the central interlining 2c to form a fabric complex, and the compartment 5c of the fabric complex is formed. Is filled with a filling material such as feathers 4. The compartment 5c and the compartment 3c as described above are provided to prevent the careless displacement of the filling by partitioning the filling in the futon in the vertical and horizontal directions.

(Problems to be solved by the invention) However, in such a conventional futon, only one end 3d side of the partition 3c is fixed by sewing and the other end 3e side is not fixed at all as a free end. In this state, when the futon is used or when the futon is handled, the filling material in the futon crosses over the free end side of the partition 3c and the compartment
There is a problem in that there is a possibility of moving within the 5c, and as a result, the filler in the futon becomes uneven as a whole and the futon becomes non-uniform.

Therefore, the function of the partition piece provided for partitioning the filling together with the compartment 5c in the futon to prevent the original displacement of the filling is impaired.

The present invention has been invented as an improvement of a method for manufacturing a comforter having a compartment and a partition as described above in order to solve the above-mentioned problems. The purpose of this is to prevent unbalanced movement of the filler in the futon by preventing inadvertent movement.

Then, the filling tool 13 is inserted into the small division chamber 12 below the small division chamber 12 and the feathers 4 are blown and filled in the same manner. In this way, from the innermost small division chamber 12 to the opening 8 side small division chamber
Over the course of 12, the filling tool 13 is introduced into each of the small division chambers 12 through the respective filling ports 16, and the feathers 4 are sequentially blown into and filled in the respective small division chambers 12. In addition, the inside of the small division chamber 12 closest to the opening 8 of the compartment 5 is filled with the feathers 4 with the filling tool 13 pulled out from the passage 14.

Then, after the feathers 4 are filled in all the small divided chambers 12 in each of the compartments 5, the duvet is manufactured by sewing the end edges 2a of the openings 8 to each other.

The futon produced in this way has the small divided chambers 12, ... Formed in the partitioned chamber 5 by the partitioned pieces 3 having the fixed ends 3a and 3b as described above. The divided feathers 4 are partitioned and closed in the small division chambers 12, ... Therefore, the feathers 4 which are partitioned and closed in the respective small division chambers 12 when the futon is used or handled are divided into the partition pieces 3, 3. …
Without crossing over and moving to the other small division room 12 side,
Therefore, the feathers 4 filled in the futon are never biased as a whole.

In addition, the filling tool 13 is thus inserted into the passage 14, and the bent tip portion 13a thereof is projected into the respective small division chambers 12 from the filling port 16 formed in the cloth piece 15 or the central interlining 2. This makes it possible to fill the feathers 4 in each of the small division chambers 12 even though the inside of the cloth fabric bag body 9 has been previously divided into small pieces.

In addition, in the above-mentioned embodiment, the lateral land 1 of the one end 3a of the partition piece 3 is used.
The attachment to the a and 1b is made by sewing, but the attaching means is not limited to this, and may be means such as heat fusion or welding by high frequency.

Further, the means for attaching the other end 3b of the partition piece 3 to the center core 2 and the means for attaching the center core 2 and the side bases 1a, 1b are not limited to the heat fusion of the embodiment, but may be means such as sewing. It may be.

Further, in this embodiment, both the cloth piece 15 and the core 2 are filled with a filling port.
16 is provided so that one passage 14 communicates with two adjacent compartments 5 through the filling port 16. However, even if the passages 14 are provided in all the compartments 5, Good.
Therefore, the filling port 16 does not necessarily have to be formed in both the cloth piece 15 and the center interlining material 2, but may be formed in only one of them.

Further, as the means for forming the filling port 16, in addition to the means for forming the cut as in the embodiment, for example, the filling port 16 is formed in the overlapping portion of a plurality of cloth pieces 15, ... As shown in FIG. It may be a means.

Further, the passage 14 does not necessarily have to be provided along substantially the entire area of the compartment 5 as in the embodiment, and the cloth piece 15 is provided in a part directly below the compartment 3 as shown in FIG. It may be formed by
As shown in the figure (b), it may be a form in which the fabric body bag 9 is formed from both ends to the adjacent chamber and the center is divided.

The passage 14 may be formed not on the side of the central interlining 2 but on the sides 1a and 1b.

Further, in addition to forming such a passage 14, without fusing the entire region of the other end 3b of the partition piece 3 as shown in FIG. 10,
When a gap 19 is formed between the other end 3b of the partition 3 at a position corresponding to the passage 14 and the center interlining 2, the filling tool is inserted from this gap 19.
It is possible to insert 13 and fill the feathers 4 in each small division chamber 12. Therefore, the formation of the passage 14 is by no means a condition.

Further, the fixing means of the cloth piece 15 is not limited to the ultrasonic welding of the embodiment, but may be means such as heat fusion or sewing.

Further, in the above-mentioned embodiment, the feathers 4 are filled in each of the small division chambers 13 by the passages 14 and the like after the formation of the small division chambers 13, ... However, it is not always necessary to fill the feathers 4 after the small division chamber 13 is formed. After that, another method is also possible in which the other end 3b of the partition piece 3 is heat-fused to the center core material 2 to form the small division chamber 13 and simultaneously the feathers 4 are filled into the small division chamber 13. .

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 as shown in FIG. It is by no means a question.

Further, the material of the lateral side 1a, 1b is by no means limited to the polyamide-based synthetic resin of the embodiment, other synthetic fibers or natural fibers, or even a mixture of synthetic fibers and natural fibers Well, the material is never a question.

However, when synthetic fibers whose edges are fused and solidified by heating are used as the materials for the above-mentioned side materials 1a and 1b, these side materials are
Feathers on the thread that came out because the edges of 1a and 1b are not frayed.
Has the advantage of not getting entangled.

In addition, since the non-woven fabric is used in the embodiment as the material of the inner core material 2, the partition piece 3, and the cloth piece 15, it is possible to obtain the advantage that these cloths are not entangled with the feathers 4. The materials of the ground 2, the partition piece 3, and the cloth piece 15 are not limited to the embodiment.

Further, in this embodiment, since the inner core material 2, the partition piece 3, and the cloth piece 15 are formed in a mesh shape having a large number of small holes, the air permeability required for the feathers 4 can be maintained and the small division chamber 12 Although there is an advantage that the compressed air sent inward escapes from the small holes and the filling work of the feathers 4 can be easily performed, the net-like formation is by no means a condition.

It should be noted that the filler in the futon is not limited to the feathers of the embodiment, and may be cotton or the like,
The type of the filling material does not matter.

Further, the shape of the filling tool 13 which is a nozzle is not limited to the shape in which the tip is bent as in the embodiment, and the shape of the tip may be any shape as long as it is simply a pipe.

(Advantages of the Invention) As described above, the present invention uses one end of a partition piece that has been conventionally made free as a free end without being fixed, that is, an end portion of the partition piece on the side ground side for cloth fabric. When the bag is formed, it is attached to both sides in advance, and then the other end of the partition is attached to the center core to form a small division chamber to form a futon. The filling in the divided chamber moves in the small divided chamber, but does not move over to the other small divided chambers over each partition piece as in the conventional case, and thus the uneven filling of the entire futon as in the conventional case. It never occurs, and it has a particularly remarkable effect that the filler can be maintained in a uniform state in the futon even after long-term use.

In particular, one end of the partition is not attached with the filling filled, but is attached to the side fabric when the fabric body bag is formed, that is, before filling with the filling, so the attachment is extremely smooth and reliable. There is a great effect that you can do it.

Further, one end of the partition piece is attached to both side fabrics in advance when forming the cloth body bag body, and then the other end of the partition piece is attached to the center cloth to manufacture the cloth fabric bag body. As described above, one end of the partition piece is attached to the side ground beforehand, so that a large amount of stock is prepared, and after that, the other end of the partition piece is simply attached to the center interlining. There is an advantage that the work efficiency of making a futon is significantly improved.

Also, since one end of the partition piece is attached to both sides of the ground, the other end is attached to the center interlining, so that the other end of the partition piece whose one end is attached to each of the front and back sides is opposed to each other through the center interlining. When attached to the center interlining in such a state, especially when attaching by heat fusion or the like, the other ends of the partition pieces facing each other through the center interlining can be attached to the center interlining at the same time. The work efficiency of making a futon can be further improved.
