Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(Embodiment)
First, the present embodiment will be described with reference to the drawings. A process of manufacturing a mounting hole for mounting a circular fan main body (for example, the diameter of the body part is 80 mm) will be briefly described. In the following description, a target cloth (woven cloth) for forming the attachment hole is referred to as a target sheet.

As shown in FIGS. 1A and 1B, the air-conditioning garment 500 includes a clothing main body 510 sewn with a material having a small air permeability, and two fan

main bodies

520 and 520 attached to both sides of the clothing main body 510. A power supply device (not shown) for supplying power to the two

fan bodies

520, 520, and a power cable (not shown) for electrically connecting the power supply device to the two

fan bodies

520, 520 Is provided. When the fan

main bodies

520 and 520 are operated, a large amount of air is taken into the clothes main body 510 from the fan

main bodies

520 and 520.

A space for allowing air to circulate between the clothing body 510 and the body or the undergarment due to the air taken in by the

fan bodies

520 and 520 causing the pressure in the clothing body 510 to become positive, causing the clothing body 510 to expand. An air flow passage) is automatically formed. Air flows upward along the surface of the body or the undergarment in the air flow passage, and is discharged to the outside, for example, around the collar or cuffs.

Here, the periphery of the collar and the cuffs play a role as the air discharge part 530. The air evaporates sweat from the body while flowing in the space between the clothing body 510 and the body or underwear, and the body is cooled by the heat of vaporization when evaporating.

When manufacturing such an attachment hole for attaching the fan main body 520 of the air-conditioning garment 500, for example, a hole smaller than the outer diameter of the fuselage part of the fan main body 520 (for example, outside the fuselage part of the fan main body 520) A hole having a radius of about 8 mm smaller than the diameter) is opened, and a cut is made to a diameter substantially the same as the outer diameter of the body portion of the fan body 520. By making the cut, the cut portion can be folded outward, and in the state where the cut portion is folded, the target sheet is attached with an inner diameter substantially the same as the outer diameter of the body portion of the fan body 520. A hole is formed.

After turning the notch, the edge of the hole and the inner edge of the reinforcing ring (reinforcing member) are precisely aligned, and the notch in the folded state is sandwiched between the reinforcing ring (reinforcing member) and the target sheet. The attachment hole can be manufactured by stitching.

Such a reinforcing ring (reinforcing member) is, for example, a ring-shaped member having a width of 10 mm made of polypropylene having a thickness of 0.5 mm and having an inner diameter slightly larger than the outer diameter of the body portion of the fan body 520.

Here, the mounting hole machining jig 100 will be described. As shown in FIGS. 2A and 2B, the mounting hole machining jig 100 includes a first member 1 serving as a jig body, and a second member 2 serving as a folding means in slidable contact with the first member 1. It is comprised by. For example, as the mounting hole processing jig 100, the mounting hole processing jig 100 corresponding to a case where the number of cut portions formed in the target sheet is 24 is assumed.

As shown in FIGS. 3A and 3B, the first member 1 (the jig body) is provided at the upper end of the cylindrical portion CY21 having the same outer diameter DA21 as the outer diameter of the body portion of the fan main body 520 and the cylindrical portion CY21. And an inclined portion SL21 that continuously decreases in the direction opposite to the cylindrical portion CY21 until the outer diameter becomes the outer diameter DA22. That is, the first member 1 has a cylindrical portion CY21 that extends from one end (hem) of the inclined portion SL21.

Further, the slant portion SL21 is formed with 24 concave portions CN21 in which an elastic portion EL31 of a second member 2 (folding means) described later can slide, and the bottom portion of the cylindrical portion CY21 has an outer diameter from the outer diameter of the cylindrical portion CY21. A cloth removal prevention part PR21 made of a thin plate having a large outer diameter is attached.

For example, the height of the cylindrical portion CY21 is about 5 mm, the height of the inclined portion SL21 is about 10 mm, and the outer diameter of the cloth removal preventing portion PR21 is about 8 mm larger than the outer diameter of the cylindrical portion CY21.

On the other hand, as shown in FIGS. 4A and 4B, the second member 2 includes 24 elastic portions EL31 whose one ends are slidably in contact with the side surface of the inclined portion SL21 from the inclined portion SL21 side of the first member 1, and A coupling portion CM31 that couples the other end of the elastic portion EL31 is provided. Moreover, the elastic part EL31 uses the member which is thermoplastic resins, such as the product made from PP (polypropylene: polypropylene), for example. The elastic part EL31 is connected at one end of a rectangle by the connecting part CM31, and the other end is arranged radially at equal intervals toward the outside of the second member 2.

Therefore, as shown in FIG. 2A and FIG. 2B, when the second member 2 is placed on the first member 1, one end of the 24 elastic portions EL31 is gently fitted into the recess CN21 and is inclined to the inclined portion SL21. One end of the elastic part EL31 reaches the vicinity of the upper part of the cylindrical part CY21. Then, by pushing the coupling part CM31 of the second member 2 downward (first member 1 side), the elastic part EL31 moves obliquely downward while sliding in a state regulated by the concave part CN21 formed in the inclined part SL21. Then, one end of the elastic part EL31 is elastically deformed so as to expand to the outside of the cylindrical part CY21.

Next, a method for manufacturing a mounting hole using such a mounting hole processing jig 100 will be described with reference to FIGS.

(First step)
In the first step, as shown in FIG. 5, an opening having an outer diameter DA41 smaller than the outer diameter of the body portion of the fan main body 520 (for example, about 8 mm smaller than the outer diameter of the body portion of the fan main body 520) in the target sheet CL41. The AP 41 is formed, and the cut CT41 is inserted until the diameter is substantially the same as the outer diameter DA42 of the body portion of the fan main body 520, so that 24 cut portions CF41 are formed. The method for forming the cut CT41 can be realized by various methods such as a method using a laser cutter for mass production or a method for scoring a cloth and cutting with scissors for small-scale production.

(Second step)
In the second step, as shown in FIGS. 6A and 6B, the opening AP41 of the target sheet CL41 processed in the first step is inserted in the direction of the arrow from the inclined portion SL21 side of the mounting hole processing jig 100. At this time, the positions of the 24 cut portions CF41 are adjusted and inserted so as to roughly match the positions of the 24 elastic portions EL31.

Further, since the inner diameter of the opening AP41 is smaller than the outer diameter of the cylindrical portion CY21, the opening AP41 of the processed target sheet CL41 is inserted in the direction of the arrow from the inclined portion side of the mounting hole processing jig 100. Thus, the 24 cut portions CF41 are divided by the cut CT41 and are directed upward along the cylindrical portion CY21 and the inclined portion SL21.

Further, in order to make the twenty-four cut portions CF41 face more reliably upward, a plastic ring having an inner diameter slightly larger than the outer diameter of the body portion of the fan body 520 (auxiliary member: for example, thickness) About 0.2 mm) may be inserted from the inclined portion side of the mounting hole processing jig 100 and inserted into the cylindrical portion CY21 until the edge of the target sheet CL41 contacts the cloth removal preventing portion PR21.

In this case, the target sheet CL41 is pressed from a ring (auxiliary member) (not shown) against a plane such as a work table on which the mounting hole processing jig 100 is placed, so that the 24 cut portions CF41 are arranged on the outer periphery of the cylindrical portion CY21. The cylindrical portion CY21 is in a substantially right angle and surely faces upward.

(Third step)
In the third step, as shown in FIGS. 7A and 7B, the connecting portion CM31 of the second member 2 is pushed down to the first member 1 side (in the direction of the arrow AR61), and one end of the 24 elastic portions EL31 is connected to the cylindrical portion CY21. Are expanded in the outer direction (directions indicated by arrows AR62 and AR63), the 24 cut portions CF41 facing upward are collectively folded outward at one end of the elastic portion EL31.

(4th process)
As shown in FIGS. 8A and 8B, the fourth step is a plastic reinforcement in which the inner diameter is slightly larger than the outer diameter of the fuselage portion of the fan body 520 in a state where the 24 cut portions CF41 are folded outward. A ring RG71 (reinforcing member: about 0.5 mm thick, for example) is inserted from the inclined portion side of the mounting hole processing jig 100, and overlaid on the cut-out portion CF41 in a folded state. Then, while moving the reinforcing ring RG71 (reinforcing member) downward, the second member 2 is pulled out in the direction of the arrow, and the reinforcing ring RG71 (reinforcing member) is completely moved down and pressed against the cloth removal preventing part PR21.

In the fourth step, the 24 cut portions CF41 are completely folded back, and the reinforcing ring RG71 (reinforcing member) is overlaid thereon. In this state, the inner edge of the target sheet CL41 and the inner edge of the reinforcing ring RG71 (reinforcing member) are in contact with the cylindrical portion CY21. That is, the reinforcing ring RG71 (reinforcing member) can be disposed at an accurate position while keeping the cut-out portion CF41 folded.

Note that the target sheet CL41 in which the opening AP41 is inserted into the first member 1 does not fall out of the first member 1 by the cloth removal prevention portion PR21 attached to the bottom of the first member 1, so the first member The target sheet CL41 can be moved while being placed on 1.

"5th process"
In the fifth step, as shown in FIGS. 9A and 9B, the reinforcing ring RG71 (reinforcing member), the cut portion CF41 of the target sheet CL41, and the target sheet CL41 are collectively formed into a ring shape using a sewing device such as a sewing machine. Suture. If necessary, the reinforcing ring RG71 (reinforcing member) may be sewn at two locations (SW81 and SW82) at the inner edge and the outer edge, or may be sewn in multiple layers.

Further, in the second step, when a plastic ring (auxiliary member) is inserted, a reinforcing ring RG71 (reinforcing member), a cut portion CF41 of the target sheet CL41, a plastic ring (auxiliary member) are used using a sewing machine or the like. ) And the target sheet CL41 are stitched together in a ring shape.

The mounting hole thus manufactured has the following advantages.
(1) The hole diameter does not increase even if force is applied to the fan main body 520 or the target sheet by the plastic reinforcing ring (reinforcing member), and the fan main body 520 cannot be removed even if a large force is applied to the fan main body 520. .
(2) Although the cut end of the woven fabric (target sheet) is likely to fray, the woven fabric is folded back and stitched together with the reinforcing ring (reinforcing member) so that the end of the fabric will not fray. .
(3) Since the hole diameter of the mounting hole is the inner diameter of the reinforcing ring (reinforcing member), a highly accurate hole diameter can be realized.
(4) A large backing cloth is not used unlike conventional mounting holes, and it is simple and can greatly reduce the cost.
(5) Since a large backing cloth is not used unlike conventional mounting holes, there is no stitching line at a position away from the outer peripheral direction of the fan main body 520, and there is little discomfort in appearance.

Further, the cut portion CF41 can be accurately folded back, and the reinforcing ring RG71 (reinforcing member) can be sewn after the inner edges are accurately aligned.

As described above, the cylindrical portion CY21 having the substantially same outer diameter as the mounting hole, and the inclined portion SL21 provided at one end of the cylindrical portion CY21 and continuously decreasing in the outer direction in the opposite direction to the cylindrical portion CY21. A first member 1 having one end, a plurality of elastic portions EL31 whose one end is in sliding contact with the side surface of the inclined portion SL21 from the inclined portion side of the first member 1, and a coupling portion CM31 that couples the other end of the elastic portion EL31. Since the second member 2 is provided, the notch portions CF41 are collectively folded outward and the reinforcing ring RG71 (reinforcing member) can be easily attached while maintaining the folded state. It can be done easily.

(Modification 1)
In the description of the embodiment and the like, the cut portion CF41 is folded outward by the tip of the elastic portion EL31 of the second member 2 (folding means), but a thin protruding portion is formed from the side surface of the cylindrical portion CY21 of the first member 1. You may make it protrude radially outward.

As shown in FIG. 10, the mounting hole processing jig 101 is provided on the cylindrical portion CY101 having the same outer diameter DA101 as the outer diameter of the body portion of the fan main body 520, and the upper end portion of the cylindrical portion CY101. An inclined portion SL101 that continuously decreases in the opposite direction until the outer diameter becomes the outer diameter DA102 is provided. That is, the mounting hole processing jig 101 has a cylindrical portion CY101 extending from one end of the inclined portion SL101. FIG. 10 shows a state in which the protruding portion PI101 protrudes outward.

Further, 24 holes are provided in the side surface of the cylindrical portion CY101, and the 24 protrusions PI101 functioning as folding means provided so as to protrude outward from the holes are provided. The protrusions PI101 are arranged radially at equal intervals toward the outside of the mounting hole processing jig 101. For example, the protrusion PI101 uses a member made of a thermoplastic resin such as PP.

For example, a mechanism for projecting the projecting portion PI101 outward causes the projecting portion 101 to project outward by an elastic body provided inside the mounting hole processing jig 101. Or you may make the protrusion part 101 protrude by a magnet and make the protrusion part 101 protrude by an air pressure.

Furthermore, a cloth removal prevention part PR101 made of a thin plate having an outer diameter larger than the outer diameter of the cylindrical part CY101 is attached to the bottom of the cylindrical part CY101.

For example, it is conceivable that the height of the cylindrical portion CY101 is about 5 mm, the height of the inclined portion SL101 is about 10 mm, and the outer diameter of the cloth removal preventing portion PR101 is about 8 mm larger than the outer diameter of the cylindrical portion CY101.

In the mounting hole manufacturing method using the mounting hole processing jig 101 as described above, in the second step, the opening AP41 of the target sheet CL41 processed in the first step is used as the inclined portion SL101 of the mounting hole processing jig 101. When inserting from the side, the positions of the 24 cut portions CF41 are adjusted and inserted so as to roughly match the positions of the 24 projecting portions PI101.

Further, in the third step, the notch CF41 is collectively folded outward by projecting the protruding portion PI101 which is the folding means outward.
In addition, about the direction which makes protrusion part PI101 which is a folding | turning means protrude outside, it cuts in notch part CF41 collectively to an outer direction by making it project diagonally downward rather than just beside, and the notch | incision of the folded state This is preferable because the portion CF41 can be held.

As described above, according to the first modification, the protrusions PI101 serving as the folding means are projected outward, whereby the cut portions CF41 are collectively folded outwardly, and the reinforcing ring RG71 (reinforcement is maintained while maintaining the folded state. Member) can be easily attached, so that the attachment hole can be easily processed.

(Modification 2)
In the description of the embodiment and the like, the cut portion CF41 is folded outward by the tip of the elastic portion EL31 of the second member 2 (folding means), but from the ejection hole portion opened in the cylindrical portion CY21 of the first member 1 The air may be ejected radially and vigorously.

As shown in FIG. 11, the mounting hole processing jig 102 is provided at the cylindrical portion CY111 having an outer diameter DA111 substantially the same as the outer diameter of the body portion of the fan main body 520, and at the upper end portion of the cylindrical portion CY111. An inclined portion SL111 that continuously decreases until the outer diameter becomes the outer diameter DA112 in the opposite direction is provided. That is, the mounting hole processing jig 102 has a cylindrical portion CY111 extending from one end of the inclined portion SL111.

Further, on the side surface of the cylindrical portion CY111, there are 24 ejection hole portions AH111 that function as folding means by causing air to be ejected vigorously toward the outside. The ejection hole portions AH111 are arranged radially at equal intervals toward the outside of the mounting hole processing jig 102.

And, a pipe from a compressed air tank (not shown) is connected to such an ejection hole AH111 via an opening / closing means such as a valve, and by opening the opening / closing means, the ejection hole AH111 has Compressed air is supplied from a compressed air tank (not shown), and the air is ejected vigorously toward the outside of the cylindrical portion CY111.

Furthermore, a cloth removal prevention part PR111 made of a thin plate having an outer diameter larger than the outer diameter of the cylindrical part CY111 is attached to the bottom of the cylindrical part CY111.

For example, the height of the cylindrical portion CY111 is about 5 mm, the height of the inclined portion SL111 is about 10 mm, and the outer diameter of the cloth removal preventing portion PR111 is about 8 mm larger than the outer diameter of the cylindrical portion CY111.

In the mounting hole manufacturing method using the mounting hole processing jig 102 as described above, in the second step, the opening AP41 of the target sheet CL41 processed in the first step is used as the inclined portion SL111 of the mounting hole processing jig 102. When inserting from the side, the positions of the 24 cut portions CF41 are adjusted and inserted so as to roughly match the positions of the 24 ejection hole portions AH111.

Further, in the third step, the cut portions CF41 are collectively folded outward by ejecting air from the ejection hole AH111, which is the folding means, as shown by the arrows.
As for the direction in which air is ejected vigorously, the cut portions CF41 are collectively folded outwardly by jetting obliquely below the side, and the folded cut portion CF41 is held. Is preferable.

As described above, according to the first modification, the air is ejected from the ejection hole AH111, which is the folding means, so that the cut portions CF41 are collectively folded outwardly, and the reinforcing ring is maintained while maintaining the folded state. Since RG71 (reinforcing member) can be easily attached, the mounting hole can be easily processed.

In the description of the embodiment and the like, the cloth removal prevention part PR21 is illustrated as a constituent element of the attachment hole processing jig 100, but the cloth removal prevention part PR21 is an essential constituent element of the attachment hole processing jig 100. is not. For example, when there is no need to move the target sheet CL41 while being placed on the first member 1, the cloth removal prevention part PR21 is not necessary.

In the description of the embodiment and the like, the recess portion CN21 for allowing the elastic portion EL31 of the second member 2 to slide on the inclined portion SL21 of the first member 1 and restricting the moving direction of the elastic portion EL31. However, if the elastic part EL31 of the second member 2 can slidably contact the inclined part SL21, the concave part CN21 is not necessary.

In the description of the embodiment and the like, a ring (auxiliary member) is used in the second step in order to more easily and accurately manufacture the mounting hole, but the ring (auxiliary member) is used as necessary. It is used and can be omitted.

In the description of Modification 1 and Modification 2, the mounting hole processing jigs 101 and 102 have a cylindrical portion (CY101, CY111) and an inclined portion (SL101, SL111) provided at one end thereof. However, the same effect can be achieved even with a configuration having only the cylindrical portion (CY101, CY111).
Further, as a configuration having only the inclined portions (SL101, SL111), a protruding portion PI101 which is a folding means is provided in the vicinity of the hem portion of the inclined portions (SL101, SL111) (a portion having substantially the same outer diameter as the mounting hole). Even if it is the structure which has the ejection hole part AH111, there can exist the same effect.

Further, in the description of the embodiment and the like, the shape of the mounting hole is described as being circular, but the shape of the mounting hole is not necessarily circular. For example, it may be oval or polygonal.

Further, in the description of the embodiment and the like, the cut portion CF41 is described as 24 sheets, but of course, it is not limited to 24 sheets. However, in the case where the shape of the mounting hole is a circle, an ellipse, or the like, it is preferable that the number of cut portions CF41 is 10 or more in order to make it with high accuracy.

In the description of the embodiment and the like, the number (24) of the elastic portion EL31, the protruding portion PI101, and the ejection hole portion AH111 is described as the same number as the number of the cut portions CF41 (24). The number of the part EL31, the projecting part PI101, the ejection hole part AH111 and the number of the cut parts CF41 do not have to be the same. For example, the positions of the cut portion CF41, the elastic portion EL31, the protrusion portion PI101, and the ejection hole portion AH111 can be increased by making the number of the elastic portions EL31, the protrusion portions PI101, and the ejection hole portions AH111 sufficiently larger than the number of the cut portions CF41. Matching is no longer necessary.

In the description of the embodiment and the like, the reinforcing ring RG71 (reinforcing member) is described as being made of plastic, but is not limited to plastic. For example, anything that can be sewn with a small elasticity such as leather may be used.

In the description of the embodiments and the like, the mounting holes of the fan main body 520 of the air-conditioning garment 500 are described as examples.
