Description

[Technical Field]

[0001] The present invention relates to a jig unit and a filling object. [Background technology]

[0002] Conventionally, feather duvets and feather jackets filled with feathers have generally been manufactured by stuffing down packs obtained by filling feathers into the interior of fabric that constitutes the feather duvet or feather jacket.

[0003] However, there is a limit to the supply of natural feathers (down), and many consumers shy away from down due to animal welfare concerns. As an alternative to down filling, woven and knitted fabrics containing mohair yarn have been proposed as a new material containing synthetic fiber materials (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-048412 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when filling the woven or knitted fabric (long fiber structure) containing mohair yarn disclosed in Patent Document 1 into the interior of the fabric that constitutes a down comforter or a down jacket, it is difficult to fill it to a uniform thickness, and there is a concern that sufficient bulkiness may not be obtained.

[0006] An object of the present invention is to provide a jig unit and a stuffing object that enable a long fiber structure to be inserted into an insertion portion while maintaining a bulky state. [Means for solving the problem]

[0007] The above object can be achieved by the present invention described below. In other words, the present invention is a jig unit comprising a tubular insertion portion having openings at both ends through which a long fiber structure is inserted, and an insertion jig for inserting the long fiber structure into the insertion portion, wherein the insertion portion extends in a straight line, and the insertion jig comprises a jig main body formed in the shape of a strip on which the long fiber structure can be placed and which can be inserted into the insertion portion, and a holding portion provided on one longitudinal end side of the jig main body and which holds one end of the long fiber structure. [Effects of the Invention]

[0008] According to the present invention, the long fiber structure can be inserted into the insertion portion while maintaining its bulkiness. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] (First embodiment) A jig unit 1 according to a first embodiment of the present invention and a stuffing object 6 manufactured using the jig unit 1 will be described below with reference to Figures 1 to 6. As shown in Figure 6, the stuffing object 6 has a long fiber structure 10 inserted into an insertion portion 2. With the long fiber structure 10 inserted into the insertion portion 2, the openings 20f, 20b at both ends of the insertion portion 2 are closed, and the stuffing object 6 becomes a part that constitutes a part of a winter coat.

Fig. 4 is a plan view for explaining the procedure for producing the stuffing object 6, and shows the inserted portion 2 into which the inserting jig 3 is inserted. Fig. 5 is a view showing a step subsequent to Fig. 4, and shows a state in which one end of the long fiber structure 10 is held by the inserting jig 3 and inserted into the inserted portion 2. Fig. 6 is a view showing a step subsequent to Fig. 5, and shows a completed state of the stuffing object 6 in which one end of the long fiber structure 10 is held by the inserting jig 3.

[0012] As shown in Figures 1, 2, and 5, the jig unit 1 includes a tubular insertion portion 2 (shown in Figure 5) having openings 20f, 20b at both ends and through which the long fiber structure 10 is inserted, and a plastic insertion jig 3 (shown in Figures 1 and 2) for inserting the long fiber structure 10 into the insertion portion 2.

[0013] In the following, arrows X, Y, and Z indicate directions that are perpendicular to one another. Arrow X may be referred to as the longitudinal direction of the insertion jig 3. Arrow Y may be referred to as the width direction of the insertion jig 3. Arrow Z is the thickness direction of the insertion jig 3. In addition, in arrow X, the direction in which the insertion jig 3 is inserted into the inserted portion 2 is indicated by arrow X1, and may be referred to as the "insertion direction."

[0014] As shown in Fig. 4, the inserted portion 2 is a part of the fabric construction 20. As shown in Fig. 4, each inserted portion 2 is constructed by overlapping a pair of fabrics 20A, 20B facing each other, with a seam s having a predetermined width (width dimension L4 of the inserted portion 2, 7 cm in this embodiment) and extending in the longitudinal direction X. As shown in Fig. 4, the fabric construction 20 is constructed to have four (plural) inserted portions 2.

[0015] As shown in Fig. 4, each insertion part 2 has openings 20f, 20b at both ends, and is configured to have an accommodation space 2S extending in the longitudinal direction X between seams s adjacent in the width direction Y for accommodating the long fiber structure 10. In this fabric structure 20, the accommodation space 2S of each insertion part 2 is filled with the long fiber structure 10 to form a stuffing 6. The openings 20f, 20b at both ends of the stuffing 6 are sewn together to form a part that constitutes a winter coat.

[0016] The pair of fabrics 20A, 20B are to form the outer fabric 20A and the inner fabric 20B of the winter coat, with the long fiber structure 10 filled between them. In this embodiment, the outer fabric 20A is made of a fabric composed of 77% nylon and 23% polyurethane, and the inner fabric 20B is made of a fabric composed of 100% polyester.

[0017] As shown in Figures 1 and 2, the insertion jig 3 includes a strip-shaped jig body 30 and a retaining fitting 4 (retaining portion) provided at one end 3f (end in the insertion direction X1) of the jig body 30 in the longitudinal direction X to hold one end of the long fiber structure 10 described later.

[0018] 5, the jig body 30 is configured in the shape of a strip, and is formed so that its longitudinal dimension L1 is longer than the axial dimension L3 of the inserted portion 2, and its width dimension L2 is approximately 0.7 times (approximately 5 cm in this embodiment) the width dimension L4 of the inserted portion 2. The jig body 30 is made of a material that can slide inside the inserted portion 2. In this embodiment, the jig body 30 is made of an acrylic plate formed from acrylic resin into a flat plate shape.

[0019] As a result, when the jig body 30 is inserted into the inserted portion 2, its both ends 3f, 3b are exposed from the openings 20f, 20b located at both ends of the inserted portion 2, and it is possible to grasp the gripping portion 31 (described below) provided on the other end 3b of the jig body 30 and press the jig body 30 in the insertion direction X1, X while pulling one end 3f of the jig body 30 (the side of the retaining fitting 4).

[0020] Furthermore, the jig body 30 is chamfered at the boundary between the front surface and the side surface, and at the boundary between the back surface and the side surface, so that the insertion portion 2 is prevented from getting caught.

[0021] Furthermore, a gripping portion 31 that functions as a handle for an operator is provided at the other end 3b of the jig body 30 in the longitudinal direction X. The gripping portion 31 is configured in a tapered shape that widens with increasing distance from the other end 3b of the jig body 30. This gripping portion 31 is a portion that an operator holds in order to push the jig body 30 in the insertion direction X1, X when inserting the long fiber structure 10 into the inserted portion 2 using the insertion jig 3.

[0022] As shown in Figures 1 and 2, the holding fitting 4 includes a rectangular holding part main body 41 that is overlapped with the surface and one end 3f of the jig body 30 and is fixed to the jig body 30 with screws, a holding piece 42 that sandwiches and holds one end of the long fiber structure 10 described later between the holding part main body 41 and the holding part main body 41, and an elastic part (not shown) that biases the holding piece 42.

[0023] The holding portion main body 41 includes a plate-shaped portion 411 and a shaft support portion 412 that rotatably supports a part 42A of the holding piece 42 as an axis.

[0024] The plate-shaped portion 411 is fixed to the jig body 30 with its longitudinal direction aligned with the width direction Y of the jig body 30 and its width direction aligned with the longitudinal direction X of the jig body 30. The longitudinal dimension of this holding portion body 41 and the width dimension of the jig body 30 are configured to be the same dimension.

[0025] The shaft support portion 412 is formed by folding back an extension portion extending from the plate-like portion 411, and is formed in a cylindrical shape into which a portion 42A of the holding piece 42 is inserted.

[0026] The elastic portion is, for example, composed of a torsion coil spring, one end of which is fixed to the shaft support portion 412 and the other end of which is fixed to the retaining piece 42, and is configured to urge the retaining piece 42 toward the plate-shaped portion 411 of the retaining portion main body 41.

[0027] The holding piece 42 is made by bending a rod-shaped metal, and has four corners and is formed in a rectangular ring shape including a portion 42 A. The holding piece 42 has a longitudinal direction that is aligned with the width direction Y of the jig body 30, and a width direction that is aligned with the longitudinal direction X of the jig body 30, with the portion 42 A inserted into the shaft support portion 412 and supported.

[0028] In this embodiment, resin L-shaped covers 5 are attached to two corners of the holding piece 42 that are distant from the shaft support portion 412. The portion of the holding piece 42 to which the L-shaped covers 5 are attached is configured to abut against the jig body 30 via the holding portion body 41. In other words, the holding piece 42 is configured so that only its two end portions abut against the jig body 30, and the long fiber structure 10 is sandwiched and held between the portion where the L-shaped covers 5 are provided and the jig body 30. In this way, both end portions of the long fiber structure 10 in the width direction are held by the holding fittings 4 (insertion jig 3).

[0029] 5, the dimensional relationship between the inserting jig 3 and the inserted portion 2 is formed so that the overall length L1 from one end 3f to the other end 3b of the inserting jig 3 (the longitudinal dimension of the jig body) is greater than the axial length L3 of the inserted portion 2. Accordingly, when the inserting jig 3 is inserted into the inserted portion 2, the one end 3f and the other end 3b of the inserting jig 3 are exposed from the openings 20f, 20b of the inserted portion 2.

[0030] As shown in Fig. 3, the long fiber structure 10 is made of "Air Flake (registered trademark)" manufactured and sold by Kurabo Industries, Ltd. Hereinafter, "Air Flake (registered trademark)" manufactured and sold by Kurabo Industries, Ltd. may be referred to as "long fiber body 12".

[0031] The long fiber structure 10 is composed of a twisted long fiber body 11 having a long fiber body 12 .

[0032] The continuous fiber body 12 is made of polyester artificial feathers that were biomimetic, based on the analysis of the shape and properties of the finest feather, "eiderdown." The continuous fiber body 12 is made of a core yarn and fiber pieces branching from the core yarn.

[0033] As shown in Figures 3(A) and 3(B), each twisted long fiber body 11 is formed by twisting two long fiber bodies 12. As shown in Figures 3(C) and 3(D), the long fiber structure 10 is formed by twisting four (a plurality of) twisted long fiber bodies 11A, 11B, 11C, and 11D (11) (shown in Figure 3(C)).

[0034] Such a long fiber structure 10 is formed by bundling a plurality of long fiber bodies 12, and is folded back (or cut) into a U shape so that the longitudinal dimension is shorter than the axial dimension of the insertion portion 2. This long fiber structure 10 is configured to be inserted into the insertion portion 2 with one end held by the retaining metal fitting 4 of the insertion jig 3.

[0035] Next, a manufacturing procedure for manufacturing the packed object 6 using the jig unit 1 will be described below with reference to FIGS.

[0036] First, for the retaining fixture 4, the retaining piece 42 is rotated in a direction away from the plate-like portion 411 against the biasing force of the elastic portion, and in this state, one end of the long fiber structure 10 is positioned between the retaining body 41 and the retaining piece 42. Thereafter, the retaining piece 42 is rotated in a direction approaching the retaining body 41 in accordance with the biasing force of the elastic portion, and the one end of the long fiber structure 10 is sandwiched and locked between the retaining body 41 and the retaining piece 42, thereby holding the one end of the long fiber structure 10 in the insertion jig 3. At this time, the long fiber structure 10 is placed on the jig body 30, and both widthwise ends of one end in the longitudinal direction of the long fiber structure 10 are sandwiched between the retaining body 41 and the retaining piece 42.

[0037] 4 and 5, one end 3f of the insertion jig 3 is brought close to the opening 20b located at the other end 3b of the inserted portion 2 and inserted. The operator holds the gripping portion 31 and pushes the insertion jig 3 in the insertion direction X1, X. As the insertion progresses, one end 3f of the insertion jig 3 is exposed from the opening 20f located at one end of the inserted portion 2. At this time, the other end 3b of the insertion jig 3 is exposed from the opening 20b of the inserted portion 2.

[0038] Thereafter, the retaining piece 42 of the retaining fitting 4 is rotated in a direction away from the plate-shaped portion 411 against the biasing force of the elastic portion, and the retaining piece 42 is separated from the plate-shaped portion 411, thereby releasing the lock of the retaining fitting 4 to one end of the long fiber structure 10.

[0039] Thereafter, only the insertion jig 3 is pulled out from the insertion portion 2, leaving the long fiber structure 10 in the insertion portion 2. In this way, the insertion of the long fiber structure 10 into the insertion portion 2 using the insertion jig 3 is completed, and the stuffing 6 is completed. Thereafter, the long fiber structure 10 is inserted into the remaining insertion portions 2 of the fabric structure 20 using the insertion jig 3 in the same procedure as described above (shown in FIG. 6). Thereafter, both ends in the longitudinal direction X of the insertion portions 2 of the fabric structure 20 are sewn together. That is, the stuffing 6 is manufactured with the long fiber structure 10 filled in each insertion portion 2, and then both ends of the stuffing 6 are sewn together to manufacture parts that constitute a winter coat.

[0040] According to the above-described embodiment, the long fiber structure 10 is inserted into the insertion portion 2 while placed on the jig body 30, and therefore, the long fiber structure 10 is inserted without applying excessive external force to the long fiber structure 10. This allows the long fiber structure 10 to have sufficient bulk inside the insertion portion 2 without being constricted or biased in the width direction Y of the insertion portion 2.

[0041] The width L2 of the jig body 30 is set to be at least 0.7 times the width L4 of the insertion portion 2. This allows the long fiber structure 10 to be inserted inside the insertion portion 2 without excessive external force being applied to the long fiber structure 10. Furthermore, the long fiber structure 10 is also arranged inside the insertion portion 2 at both ends of the insertion portion 2 in the width direction Y, thereby realizing a configuration in which the long fiber structure 10 is uniformly arranged across the entire width of the insertion portion 2.

[0042] The longitudinal dimension L1 of the jig body 30 is configured to be longer than the axial dimension L3 of the insertion portion 2. This allows the long fiber structure 10 to be inserted into the insertion portion 2 without excessive external force being applied to the long fiber structure 10.

[0043] The retaining metal fittings 4 (retaining portions) are configured to be able to abut against both end portions of the jig body 30 in the width direction Y and hold one end of the long fiber structure 10. This allows the long fiber structure 10 to be disposed inside the inserted portion 2 at both end portions of the inserted portion 2 in the width direction Y, thereby realizing a configuration in which the long fiber structure 10 is uniformly disposed across the entire width of the inserted portion 2.

[0044] Furthermore, the insertion jig 3 has a gripping portion 31 that becomes wider at the other end side opposite to one end 3f of the jig body 30 as it gets further away from the other end 3b. This allows the jig body 30 to be pushed in the insertion directions X1, X while being held by the gripping portion 31, thereby further improving workability.

[0045] The width of the jig body 30 is set to 5 cm or more, which allows the long fiber structure 10 to have sufficient bulk when inserted into the insertion portion 2.

[0046] In addition, in a stuffing object 6 including an insertion portion 2 and a long fiber structure 10 inserted into the insertion portion 2 using an insertion jig 3, the long fiber structure 10 is formed by twisting two (a plurality of) long fiber bodies 12A, 12B each containing long fibers. As a result, the long fiber structure 10 can have sufficient bulk when inserted into the insertion portion 2 because it is formed by twisting two (a plurality of) long fiber bodies 12A, 12B each.

[0047] The long fiber structure 10 is configured to have four (plural) twisted long fiber bodies 11, each of which is configured by twisting two (plural) long fiber bodies 12A, 12B, and four twisted long fiber bodies 11A, 11B, 11C, 11D (11). This allows the long fiber structure 10 to have even more sufficient bulk when inserted into the insertion portion 2.

[0048] (Second embodiment) A second embodiment of the present invention will be described below with reference to Figs. 7 to 9. Fig. 7 is a perspective view showing an insertion jig 3A constituting a jig unit 1A according to the second embodiment of the present invention. Fig. 8 is a perspective view showing a state in which one end of a long fiber structure 10 is held by the insertion jig 3A. Fig. 9 is a plan view for explaining the procedure for producing a stuffed object 6, showing a state in which one end of the long fiber structure 10 is held by the insertion jig 3A and inserted into an inserted portion 2. The jig unit 1 of the first embodiment and the jig unit 1A of the second embodiment differ in the configuration of the insertion jig 3A (3). In the second embodiment, parts having the same shape or configuration as those in the first embodiment are assigned the same reference numerals as those in the first embodiment, and description of those parts will be omitted.

[0049] As shown in Figures 5 and 6, the insertion jig 3A includes a jig body 30A having a substantially rectangular plate shape, a holding plate 4A (holding portion) provided on one end 3f side (one end side) of the jig body 30A in the longitudinal direction X, which holds one end of the long fiber structure 10 by sandwiching it between the jig body 30A and the holding plate 4A, and an anti-slip portion 7.

[0050] Furthermore, one end 3f of the jig body 30A in the longitudinal direction X is provided with a tapered portion 32 that narrows toward the tip. This tapered portion 32 is a portion that is brought close to the opening 20f of the inserted portion 2 when the inserting jig 3A is inserted into the inserted portion 2, and the inserting jig 3A is inserted into the inserted portion 2 with the tapered portion 32 positioned on the side of the insertion direction X1, X.

[0051] The holding plate 4A is provided on the other end side of the tapered portion 32 provided on the jig body 30A. That is, the holding plate 4A is provided at a position spaced from one end 3f of the jig body 30A toward the other end side.

[0052] The holding plate 4A is formed in a rectangular plate shape and is configured so as to be able to sandwich and hold one end of the long fiber structure 10 between itself and the jig body 30A. The holding plate 4A of this embodiment is formed so that its width is substantially the same as that of the jig body 30A, and its length is shorter than that of the jig body 30A.

[0053] One longitudinal end of the holding plate 4A is supported by the jig body 30A. In this embodiment, with the holding plate 4A and the jig body 30A overlapping each other, one end of the holding plate 4A and the jig body 30A are wrapped with, for example, adhesive tape, so that the holding plate 4A is supported by the jig body 30A.

[0054] As a result, the holding plate 4A is placed in contact with the jig body 30A in its natural state. When sandwiching the long fiber structure 10 between the holding plate 4A and the jig body 30A, the worker moves the other end of the holding plate 4A away from the jig body 30A, inserts the long fiber structure 10 between the jig body 30A and the holding plate 4A, and then releases the holding plate 4A. At this time, the holding plate 4A approaches the jig body 30A, and one end of the long fiber structure 10 is sandwiched and held between the jig body 30A and the holding plate 4A.

[0055] In this embodiment, one end of the holding plate 4A and the jig body 30A are supported in an overlapping state by, for example, wrapping adhesive tape around them, but instead of adhesive tape, they may be supported by, for example, a circular rubber band, or adhesive or a magnet may be used to maintain the overlapping state of one end of the holding plate 4A and the jig body 30A.

[0056] The anti-slip portions 7 are attached to the inner surfaces (contact surfaces with the long fiber structure 10) of the holding plate 4A and the jig body 30A. The anti-slip portions 7 are portions that generate friction with the long fiber structure 10. In this embodiment, sandpaper is used as the anti-slip portions 7. Alternatively, the inner surfaces of the holding plate 4A and the jig body 30A may be textured to generate friction, or a sheet made of natural rubber, synthetic rubber, or the like may be used instead of the sandpaper used in this embodiment. By providing the anti-slip portions 7 on the inner surfaces of the holding plate 4A and the jig body 30A, the long fiber structure 10 is prevented from falling off between the jig body 30A and the holding plate 4A due to friction.

[0057] When manufacturing a stuffed object 6 using such a jig unit 1A, one end of the long fiber structure 10 is sandwiched between the holding plate 4A and the jig body 30A, and one end of the long fiber structure 10 is held by the inserting jig 3. With this state, the tapered portion 32 of the inserting jig 3A is brought close to the opening 20b located at the other end 3b of the inserted portion 2 and inserted. As the insertion progresses, the tapered portion 32 of the inserting jig 3A becomes exposed from the opening 20f located at one end of the inserted portion 2. At this time, the other end 3b of the inserting jig 3A is exposed from the opening 20b located at the other end 3b of the inserted portion 2.

[0058] Thereafter, the other end of the holding plate 4A is separated from the jig body 30A, and the inserting jig 3A alone is pulled out from the inserted portion 2, leaving the long fiber structure 10 in the inserted portion 2. In this manner, the insertion of the long fiber structure 10 into the inserted portion 2 using the inserting jig 3A is completed, and the stuffed object 6 is completed.

[0059] According to the above-described embodiment, the long fiber structure 10 is inserted into the insertion portion 2 while placed on the jig body 30A, and therefore, the long fiber structure 10 is inserted without applying excessive external force to the long fiber structure 10. This allows the long fiber structure 10 to have sufficient bulk inside the insertion portion 2 without being constricted or biased in the width direction Y of the insertion portion 2.

[0060] Furthermore, the holding plate 4A (holding portion) of the jig unit 1A in the second embodiment protrudes less from the jig body 30A than the holding fitting 4 of the jig unit 1A in the first embodiment, so the holding plate 4A reduces the load on the inserted portion 2 compared to the holding fitting 4, allowing the long fiber structure 10 to be inserted into the inserted portion 2.

[0061] The holding plate 4A (holding portion) is provided at a position spaced from one end 3f of the jig body 30A toward the other end 3b, and has a tapered portion 32 that narrows toward one end on the side of the holding plate 4A of the jig body 30A. This allows the long fiber structure 10 held by the inserting jig 3A to be inserted into the inserted portion 2 with the tapered portion 32 at the front. When the inserting jig 3A is inserted into the inserted portion 2 with the tapered portion 32 of the inserting jig 3A at the front, the workability during insertion is improved.

[0062] The insertion jig 3A also includes a holding plate 4A that sandwiches and holds one end of the long fiber structure 10 between the jig body 30A and the holding plate 4A, and an anti-slip portion 7 is interposed between at least one of the jig body 30A and the holding plate 4A and the long fiber structure 10. The provision of the anti-slip portion 7 makes it possible to prevent the long fiber structure 10 from falling out from between the jig body 30A and the holding plate 4A.

[0063] The present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and the following modified examples are also included in the present invention.

[0064] In the above embodiment, the width dimension L2 of the insertion jigs 3, 3A is 5 cm, the width dimension L4 of the inserted portion 2 is 7 cm, and the insertion jigs 3, 3A are formed to have a dimensional relationship such that the width dimension is approximately 0.7 times the width dimension of the inserted portion 2, but the present invention is not limited to this. The width dimension L2 of the insertion jigs 3, 3A is preferably 5 cm or more and 5.5 cm or less. Furthermore, the width dimension of the insertion jigs 3, 3A only needs to be 0.7 times the width dimension of the inserted portion 2 or more, and it only needs to be formed to have a dimensional relationship that allows the insertion jigs 3, 3A to be inserted into the inserted portion 2.

[0065] In the above embodiment, the long fiber structure 10 is formed by twisting four (a plurality of) long fiber twisted bodies 11, each of which is formed by twisting two long fiber bodies 12A and 12B, but the present invention is not limited to this. The long fiber structure 10 may be formed by twisting three or less or five or more long fiber twisted bodies, or may be formed by bundling (not twisting) a plurality of long fiber bodies 12, although this may result in a slight loss of bulkiness, or may be formed by molding a plurality of long fiber bodies 12 into a predetermined shape.

[0066] The long fiber structure may be configured to contain other fibers in addition to the long fiber body 12. Alternatively, any long fiber structure containing long fibers is within the scope of the present invention, even if it does not use "Air Flake (registered trademark)" manufactured and sold by Kurabo Industries, Ltd.
