[Prior art]

 Japanese Utility Model Laid-Open No. Sho 62-190569 discloses a three-dimensional quilting futon in which partitions are obliquely extended and arranged. According to this futon, since the partition is extended obliquely, there is an advantage that the heat retention property is improved.

[0003] By the way, as is well known, in a three-dimensional quilted duvet, a plurality of compartments are formed inside the futon by vertical and horizontal partitions, and the interiors of the compartments are filled with batting such as feathers. At the intersection of the vertical strip and the horizontal strip, a notch is formed in one partition, and the other strip is inserted through this notch. As a result, one of the partitions can be extended in the thickness direction of the futon to stand, and as a result, the heat retaining property of the futon can be improved.

However, the technique disclosed in the above publication does not disclose a specific configuration of an intersecting portion between a vertical section and a horizontal section. If a large cut is formed in the diagonally extending partition at this intersection, the feathers (filling pad) will move through this cut. It is also conceivable to form a cut in the middle of the partition to reduce the cut length, but in this case, the cut breaks and spreads as the use is repeated, and the amount of movement of the feathers decreases. It will gradually increase. Therefore, it is necessary to take measures to prevent the incision from being enlarged, which causes inconvenience such as the manufacturing of the futon becomes complicated.

【Example】

 A solid quilting futon (hereinafter referred to as a futon) 1 according to a first embodiment of the present invention will be described with reference to FIGS. In addition, in the accompanying drawings, the thickness and dimensions of the members are schematically illustrated as appropriate for easy understanding. In addition, in FIG. 3, for simplification of description, the description of the vertical section is omitted.

The futon 1 is used as a comforter. The futon 1 is arranged between the outer lining 12 and the outer lining 20 in which the peripheral edges 12 and 22 are fixed to each other by the sewing thread 4 to form a closed space therein, and the outer lining 10 and the lining 20. It is mainly composed of a long vertical section 30 and a long horizontal section 40 that connect the two. By the vertical and horizontal partitions 30 and 40, a plurality of compartments 2 formed in a rectangular shape in plan view are formed between the outer material 10 and the lining 20. As the vertical and horizontal partitions 30 and 40, in this example, a material having high flexibility such as a relatively thin cloth is used. Inside the compartment 2, the batting 3 is stored. In this example, as the batting 3, feathers mainly composed of down are used. The basic structure described above is almost the same as that of the well-known three-dimensional quilting futon.

In the futon 1 of the present example, the vertical piece (one piece) 30 is extended in the inclination direction in the cross section (see FIG. 2) along the width direction thereof. When viewed in cross section as a whole, the longitudinal section 30 is roughly configured in a wavy shape in which peaks and valleys are alternately arranged, and the peaks and valleys are respectively longer than the outer material 10 or the lining 20. It is sewn and fastened along the direction (vertical direction in FIG. 1). In the present specification, the term "longitudinal section" refers to a portion that is inclined and extended from one of the peaks or valleys to the other. The vertical section 30 is provided so as to extend from one end (upper end in FIG. 1) to the other end (lower end in FIG. 1) in the length direction of the futon 1.

In each of the longitudinal sections 30, the side edges of the tape-shaped wide portion 31 formed to be wide and the tape-shaped narrow portion 32 formed to have a smaller width than the side edges facing each other are sewn with sewing thread. 33, it is constructed by stitching and fastening the stitches along the length direction (thickness direction of the paper surface in FIG. 2) from the start end to the end. As shown in FIG. 5, the narrow portion 32 has a cut portion 32a formed over the entire width thereof. The horizontal section 40 is inserted into the inside of the notch 32a at the intersection with the vertical section 30. The wide portion 31 is sewn to the front material 10 or the lining material 20 at a crossing portion with the horizontal material piece 40 by a sewing thread for sewing the side edges of the horizontal partition piece 40 to the outer material 10 or the lining material 20, respectively. As a result, as shown in FIG. 4, in the vicinity of the horizontal section 40, the wide portion 31 is brought close to the front material 10 or the lining material 20, and therefore, the side portion of the wide portion 31 is sewn. The narrowed portion 32 is extended along the thickness direction (front and back direction) of the futon 1. As the wide portion 31 is separated from the horizontal section 40, the wide portion 31 is deformed by its own flexibility, and as shown in FIG. 2, the wide portion 31 extends obliquely in a cross section.

As shown in FIG. 2, the vertical strips 30 described above are fastened to the vertical tapes 50 and 60 on the outer material side fixed to the inner surface 11 of the outer material 10 and to the inner surface 21 of the lining material 20. It is constructed by fixing the side edges of the lining side facing the vertical tapes 70, 80 and 90 to each other. Each of the vertical tapes 50 to 90 is extended along the length direction of the duvet 1, and both ends in the length direction of the longitudinal tape are fixed to the periphery of the futon 1 by the sewing thread 4 at the periphery of the futon 1. It is worn.

The vertical tape 50 is fixed to the outer material 10 by a sewing thread 53 along the length direction of the vertical tape at a position between the widthwise central portion and one side edge 51. The area between the side edge 51 and the sewing thread 53 is the narrow portion 32. The area between the other side edge 52 of the vertical tape 50 and the sewing thread 53 is the wide portion 31.

The vertical tape 60 is separated from the vertical tape 50 and arranged in parallel therewith. The vertical tape 60 has a structure similar to that of the vertical tape 50, and is fixed to the outer material 10 by a sewing thread 63. An area between the one side edge 61 and the sewing thread 63 in the vertical tape 60 is a narrow portion 32. The area between the other side edge 62 and the sewing thread 63 of the vertical tape 60 is the wide portion 31.

The vertical tape 70 on the lining side has a width slightly narrower than that of the vertical tape 50. The vertical tape 70 is fixed to the lining 20 by a sewing thread 73 along the length direction at a position near one side edge 71. The area between the sewing thread 73 and the other side edge 72 of the vertical tape 70 is the wide portion 31.

The vertical tape 80 is separated from the vertical tape 70 and arranged in parallel therewith. The vertical tape 80 is arranged at a position between the vertical tape 50 and the vertical tape 60. The vertical tape 80 has a structure in which the vertical tape 50 is turned upside down. The vertical tape 80 is fixed to the lining 20 with a sewing thread 83. A region between one side edge 81 of the vertical tape 80 and the sewing thread 83 is a narrow portion 32. The area between the other side edge 82 of the vertical tape 80 and the sewing thread 83 is the wide portion 31.

The vertical tape 90 is separated from the vertical tape 80 and arranged in parallel therewith. The vertical tape 90 has a width narrower than that of the vertical tape 70. The vertical tape 90 is fixed to the lining 20 by a sewing thread 93 in the vicinity of one side edge 91 thereof. A region between one side edge 91 of the vertical tape 90 and the sewing thread 93 is a narrow portion 32.

The horizontal section 40 is provided extending from one end (left end in FIG. 1) to the other end (right end in FIG. 1) in the width direction of the futon 1. As shown in FIG. 3 and FIG. 5, each horizontal section 40 has a long first horizontal tape (first tape) 41 and a second horizontal tape (second tape) formed in a tape shape having substantially the same width. The tape 42 is mainly used. One side edge of the horizontal tape 41 is sewn and fixed to the inner surface 11 of the dress material 10. One side edge of the horizontal tape 42 is sewn and fixed to the inner surface 21 of the lining 20. The opposite side edges of the horizontal tapes 41 and 42 are sewn together by a sewing thread 43 and fixed. The width of the horizontal strip 40 is set to be substantially equal to the width of the narrow portion 32 of the vertical strip 30. More specifically, in this example, the width of the narrow portion 32 is set to be slightly longer (about 5 mm to 10 mm) than the width of the horizontal section 40.

Next, a method of manufacturing the futon 1 according to this example will be described. First, the manufacturing procedure of the outer material 10 will be described mainly with reference to FIG. A long (for example, about 100 m) original fabric 100 to be the outer material 10 is prepared. The longitudinal tapes 50 and 60, which are also long, are arranged on one surface of the original fabric 100 at predetermined intervals along the lengthwise direction, and these are placed on the original fabric 100. Sew with sewing threads 53 and 63 along the extending direction. At this time, the positions of the sewing threads 53 and 63 are set to positions between the widthwise central portions of the vertical tapes 50 and 60 and one of the side edges 51 and 61.

Next, the horizontal tapes 41 are arranged in parallel to each other at intervals in a direction orthogonal to the vertical tapes 50 and 60 fixed to the raw fabric 100 as described above. After that, or at the same time, the horizontal tape 41 is sewn to the original fabric 100 with a sewing thread over the entire length in the length direction. After that, or at the same time as this sewing operation, the vertical tapes 50 and 60 are cut from the one side edge 51 and 61 to just before the position of the sewing thread 53 to form a cut portion 32a. The position of the cut portion 32a is set to a position very close to the stitching position between each horizontal tape 41 and the original fabric 100.

Next, the long raw fabric 100 is cut into a predetermined length (the length corresponding to the futon 1) together with the long vertical tapes 50 and 60. As a result, the dress material 10 having the predetermined shape having the vertical tapes 50 and 60 can be obtained.

Next, the manufacturing procedure of the lining 20 will be described mainly with reference to FIG. The procedure for manufacturing the lining 20 is almost the same as the procedure for manufacturing the outer material 10. That is, a long raw fabric 200 to be the lining 20 is prepared, and the long vertical tapes 70, 80, 90 are provided on one side of the raw fabric 200 along the length direction at predetermined intervals. The vertical tapes 70, 80, 90 are sewn to the original fabric 200 with sewing threads 73, 83, 93. Then, the horizontal tapes 42 are arranged in parallel with each other with a space therebetween. After that, or at the same time, the horizontal tape 42 is sewn to the raw fabric 200 with a sewing thread. After that or simultaneously with this sewing operation, the vertical tapes 80 and 90 are cut from the one side edge 81 and 91 to just before the position of the sewing thread 83 or 93 to form the cut portion 32a. Then, the long raw fabric 200 is cut into the same length as the outer material 10 together with the vertical tapes 70, 80 and 90. As a result, the lining 10 having the predetermined shape having the vertical tapes 70, 80, 90 and the like can be obtained.

In the method for manufacturing the futon 1 in this example, as described above, since the vertical and horizontal tapes are continuously sewn to the original fabric 100 or 200, it is easy to automate the manufacturing work, and the manufacturing cost is increased. Has the advantage that it can be reduced.

Then, the inner surface 11 of the outer material 10 and the inner surface 21 of the lining material 20 obtained as described above are opposed to each other. Here, in this example, the outer material 10 is returned in the directions shown by the arrows P and Q in FIG. 8 so that the inner surface 11 of the outer material 10 faces the lining material 20. As a result, the horizontal tapes 41 and 42 are aligned as shown in FIG. Further, as shown in FIGS. 2 and 4, the vertical tapes 50 and 60 and the vertical tapes 70, 80, 90 do not match. Next, the narrow portion 32 of the vertical tape 50, 60, 80, 90 is separated from the horizontal tape 41 or 42. That is, when the lateral tapes 41 and 42 are sewn, the narrow portion 32 is sewn to the front material 10 or the lining material 20. Therefore, an operator pulls the vicinity of the side edge of the cut portion 32a from both sides with the horizontal tape 41 or 42 interposed therebetween, so that the cloth forming the narrow portion 32 is partially unraveled. As a result, the narrow portion 32 can be separated from the lateral tape 41 or 42. This advantage can be obtained even when the vertical tape is made of a material such as paper that is easily broken.

After that, the side edges of the vertical tapes 50, 60 and the side edges of the vertical tapes 70, 80, 90 are sewn together. In this example, since the narrow portion 32 is detached from the lateral tapes 41 and 42 in advance, this sewing operation can be easily performed. Before and after this work, the opposite side edges of the horizontal tapes 41 and 42 are sewn together.

By the above procedure, the partition 2 can be provided between the outer material 10 and the lining 20. Further, the side edges of the vertical tapes 50/60 and the side edges of the vertical tapes 70/80/90 are sewn together to obtain the vertical partition 30 having the wide width portion 31 and the narrow width portion 32. Further, the lateral partition cloth 40 can be obtained by sewing the lateral tape 41 and the lateral tape 42 together. Here, when the horizontal partition cloth 40 is composed of a single piece of fabric, it is necessary to sew both side edges to the outer material and the lining material, which is extremely troublesome in the actual work using the sewing machine. It becomes a thing. However, in this example, the work of sewing the side edges of the horizontal tape 41 and the horizontal tape 42 that are opposed to each other is significantly easier than this. Therefore, in the futon 1 of this example, the work of fastening the horizontal partition cloth 40 to the front and back cloths can be made efficient.

According to the futon 1 of the present example, since the cut section 32a is provided in the vertical section 30 and the horizontal section 40 is inserted at a position corresponding to the cut section 32a, the vertical section 30 and the horizontal section 30 are inserted. At the intersection with the partition 40, both partitions can be stood. Therefore, the bulkiness of the futon 1 can be obtained at this intersection, and the heat retaining property of the futon 1 can be improved.

Next, the side edge 12 of the outer material 10 and the side edge 22 of the lining 20 are sewn together with the sewing thread 4. However, at this time, in the side edge of the futon 1 facing one end of each horizontal section 40 (for example, the side edge at the right end in FIG. 1), sewing is performed at the position facing each horizontal section 40. Instead, an opening (not shown) is formed. Next, a hose for blowing a feather (hereinafter referred to as a blowing hose) is caused to enter the inside of the futon 1 through the opening along the horizontal section 40.

In the futon 1 of this example, a cut portion 32a is formed in the vertical cut piece 30 at the intersection of the vertical cut piece 30 and the horizontal cut piece 40, and the horizontal cut piece 40 is inserted through the cut portion 32a. Therefore, as shown in FIG. 5, the space S ₁ and the space S ₂ can be formed on both the front and back surfaces of the horizontal section 40. Therefore, the tip of the blowing hose can enter the interior of each compartment 2 from the space S ₁ or the space S ₂ . Therefore, according to the futon 1 of the present example, it is possible to fill the inside of the futon 1 with the battings 3 by sequentially filling the feathers as the battings 3 from the innermost section 2. After filling a predetermined amount of the batting 3, the opening partly formed on the side edge of the futon 1 is sewn and closed.

Further, in the futon 1 of this example, since both the horizontal section 40 and the vertical section 30 are made of a highly flexible material, for example, cloth, the blowing hose is provided in the space S ₁ and There is an advantage that the work of inserting it into S ₂ is easy.

In addition, in the futon 1 of this example, since the length of the cutout portion 32a is set to a distance slightly longer than the width of the horizontal section 40, it is easy to insert the blow-in hose. The work can be further facilitated.

Further, in the futon 1 of this example, since the cutout portion 32a is formed in the narrow width portion 32 formed with a narrow width, the spaces S 1 and S ₂ formed by the cutout portion 32a are formed. The area of can be made small within a range that does not make it difficult to insert the blowing hose. Therefore, according to the futon 1 of this example, after filling the feathers as the batting 3, the movement amount of the batting 3 via the notch 32a can be suppressed to an extremely low level so as not to cause an actual failure. There is an advantage that you can. On the other hand, it is conceivable to form a notch in the wide portion 31 and insert the horizontal section 40 through this notch, but this causes the width of the notch to become too large and the movement amount of the batting 3 to be increased. This causes an increase in the amount of padding 3 and uneven distribution of the batting 3 causes a decrease in heat retention performance. It is also conceivable to partially make a cut in the wide portion 31 to form a short cut portion, but this makes it relatively easy to make a cut with a uniform cut width in a highly flexible fabric. It is difficult, and with repeated use, the end portion of the cut portion may break and the cut width may increase, and the movement amount of the batting 3 may increase. It may be possible to take special measures to prevent breakage of the notch, but this would increase the number of manufacturing processes, material costs, etc., making it practically difficult to implement. In the futon 1 of this example, since the cut portion 32a is formed in the narrow width portion 32 and the horizontal section 40 is inserted therethrough, the above inconvenience is solved and a high quality futon is provided at a low cost. There is an advantage that it can be provided.

Further, according to the futon 1 of the present example, as shown in FIG. 2, the longitudinal section 30 is extended so as to be inclined in the cross section, so that the futon 1 is protected. There is an advantage that the heating ability can be improved. Generally, when the partition is extended in a direction orthogonal to the surface material 10, the density of batting on both sides of the partition decreases, and ventilation is apt to occur. This causes problems such as the need to increase the filling amount. According to the futon 1 of this example, the slanted vertical strips 30 can prevent the heat insulating performance from being lowered in the vicinity of the vertical strips 30, and even if the filling amount of the batting 3 is constant, There is an advantage that the heat retention performance can be improved.

Further, according to the futon 1 of the present example, since the vertical section 30 is inclined in the oblique direction, it is possible to improve the flexibility of the entire futon 1. That is, when the futon is bent when the partition is extended in the direction orthogonal to the surface 10, the partition needs to be bent in a plane parallel to the surface thereof. Therefore, there are restrictions such as the use of a highly flexible material for the partition. According to the futon 1 of this example, since the vertical strip 30 is inclined in an oblique direction, when the futon 1 is bent, the vertical strip 30 is bent in a direction intersecting the surface thereof. Therefore, the folding performance of the futon 1 can be easily improved. Therefore, during use, the comforter 1 can be flexibly bent along the body of the user, and the heat retention performance of the comforter 1 can be further improved. Moreover, there is an advantage that the work of storing the futon 1 becomes easy.

In the above embodiment, the constituent members such as the partition and the outer material are fixed to each other by using the sewing thread, but other fixing means such as an adhesive can be used. .

Further, in the above-described embodiment, the vertical strip 30 is extended in the tilt direction, but instead of this, the horizontal strip 40 can be extended in the tilt direction.

Next, a futon 300 according to a second embodiment of the present invention will be described with reference to FIGS. 10 to 14. In the description of the futon 300 according to the present example, the configurations that are basically the same as those in the first example are designated by the same reference numerals, and the detailed description will be omitted. The futon 300 of the present example is different from the futon 1 of the first embodiment in that a horizontal strip 400 (see FIG. 12) extending in a slanting direction in a cross section is used instead of the horizontal strip 40 described above. .

The horizontal section 400 is mainly composed of a horizontal tape 410 sewn on the outer material 10 and a horizontal tape 420 sewn on the lining 20. The opposite side edges of the horizontal tape 410 and the horizontal tape 420 are sewn to each other by a sewing thread 430. The horizontal tape 410 and the horizontal tape 420 are displaced from each other by a slight amount (about 3 cm in this example) in the extension direction (vertical direction in FIG. 12) of the longitudinal strip 30 (see FIG. 12). As a result, the horizontal strip 400 is inclined, and on the other surface side of the horizontal strip 400 (on the right side in FIG. 13), the horizontal strip 400 is provided between the notch 32a of the narrow portion 32 and the horizontal strip 400. , A gap S ₃ is formed. Also in this example, the cut length of the cut portion 32a is longer than the length L ₂ of the horizontal section 400 in the thickness direction of the futon 1 (that is, the length in the vertical direction in FIG. 13). Has been done.

In addition, in this example, the extension piece 301 (see FIG. 13) is attached to the narrow portion 32 in the vicinity of each notch 32a formed in the narrow portion 32 of the vertical partition 30. It differs from the futon 1 of the first embodiment. The extension piece 301 is made of a rectangular fabric. As shown in FIG. 13, the extension piece 301 is sewn to the narrow portion 32 with the sewing thread 302. The extension piece 301 is set to have such a length that it can cover the gap S ₃ on the side of the one end 301a thereof. The lower edge portion 301b of the extension piece 301 is vertically aligned with the end of the wide portion 31 (not shown in FIG. 13) of the vertical strip 30 which is arranged between the lower edge portion 301b and the lining 20. The partition 30 is sewn and fastened along the extending direction (left-right direction in FIG. 13). The side edges of the one end portion 301a covering the gap ₃ except the lower end portion 301b are not fixed anywhere and are movable.

Further, in the futon 300 of the present example, the narrow portion 32 that partially interferes with the slanted horizontal section 400 has a predetermined length from one end of the cut portion 32a (see FIG. 13). It is designed not to be fixed to the wide portion 31 by the distance L ₁ ).

Next, a method of manufacturing the futon 300 according to this example will be described. In the futon 300 of this example, after forming the cut portions 32a in the narrow width portion 32 of the vertical strip 30, the extension piece is provided at a position near each cut portion 32a as shown in FIG. Sew 301. Then, similarly to the first embodiment, the side edges of the horizontal tape 410 and the horizontal tape 420 which are opposed to each other are sewn together. Then, as shown in FIG. 13, on one surface side (left side in the figure) of the horizontal section 400, a part of the narrow section 32 contacts the horizontal section 400, and the lower end of the narrow section 32 is Turn up by the length indicated by medium code L ₁ . On the other hand, on the other surface side (right side in FIG. 13) of the horizontal strip 400, a gap S ₃ is formed between the cutout portion 32 a of the narrow portion 32 and the horizontal strip 400. Then, the lower edge portion 301b of the extension piece 301 is sewn to the end portion of the wide portion 31 of the vertical segment 30.

According to the futon 300 of the present example, since the horizontal section 400 is also arranged so as to be inclined in the cross section, as compared with the futon 1 described in the first embodiment, the heat retention performance and the flexibility are further improved. Can be improved.

Further, in the futon 300 of this example, since the extension piece 301 is provided, most of the gap S ₃ formed on the lateral side of the horizontal tape 400 can be substantially closed. This makes it possible to prevent the movement of the feathers as the batting 3 through the gap S ₃ . Further, since the extension piece 301 and the horizontal tape 400 are not directly fixed to each other, when the filling hose 3 is filled, the extension piece 301 is deformed when the blow-in hose comes in, and this blow-out piece 301 is deformed. It is possible to allow the intrusion of the plug-in hose. Therefore, there is also an advantage that filling work can be performed without support.
