Description

  The present invention relates to a method for producing a fan mounting portion for mounting a fan.

Conventionally, a cooling garment equipped with a fan has been used as a garment worn when working in a high-temperature environment such as an ironworks or an outdoor construction site in summer.
This fan includes a fan main body and a fixing ring for attaching the fan main body to the cooling garment. The fan is pushed into the mounting hole from the front side of the cooling garment, and the fixing ring is attached from the back side. At this time, the flange portion of the fan main body and the end portion of the fixing ring sandwich the edge portion of the attachment hole, so that the fan is attached to the fan attachment portion of the cooling garment.

A conventional method for producing a fan mounting portion is disclosed in Patent Document 1, for example. The manufacturing method of the fan attachment part of this patent document 1 mainly comprises five processes.
In the first step, a lining is assigned to the formation position of the fan mounting portion in the sheet-like member, and the sheet-like member and the lining have a shape that is the same as or slightly larger than the shape of the outer edge of the cylindrical portion of the fan body. Suture along the frame line.
Next, in the second step, an opening hole smaller than the shape of the first frame-like line is formed inside the stitched portion that is a seam formed by stitching along the first frame-like line.
In the third step, a plurality of cuts are made in the sheet-like member and the backing between the opening hole and the stitching portion so as to go from the opening hole to the stitching portion and not reach the stitching portion.
Further, in the fourth step, the non-stretchable ring-shaped reinforcing plate having the inner edge slightly larger than the outer edge shape of the cylindrical portion is brought into contact with the sheet-like member, and the opening hole is formed in the inner edge of the reinforcing plate. The entire lining is pulled out to the side on which the reinforcing plate is arranged through the opening hole, and the first insertion part which is a part of the sheet-like member cut in the third step and The opening part which inserts a cylindrical part is formed by turning over with the 2nd incision part which is the part of the lining in which it cut | incised in the 3rd process, and folding back outside.
Finally, in the fifth step, the sheet-like member and the lining are stitched so as to surround the opening along the second frame-like line having a shape larger than the shape of the first frame-like line.

Japanese Patent No. 5672642

The manufacturing method of the fan mounting portion mainly requires that the manufacturing of the fan mounting portion does not take time and that the fan mounting portion capable of easily mounting the fan main body can be manufactured.
In the fan attachment portion manufacturing method of Patent Document 1, in the third step, a plurality of sheet members and linings between the opening hole and the stitching portion are provided so as to face the stitching portion from the opening hole and not reach the stitching portion. The first cut and the second cut are created. If it does so, it will take time and effort for preparation of a fan attachment part for the work which creates this 1st notch part and the 2nd notch part.

Moreover, in the manufacturing method of the fan attachment part of patent document 1, in a 1st process, a lining is applied to the formation position of the fan attachment part in a sheet-like member, and a sheet-like member and a lining are the same as the shape of the outer edge of a cylindrical part. Sew along the first frame-like line having a slightly larger shape. In the fourth step, the non-stretchable ring-shaped reinforcing plate having the inner edge slightly larger than the outer edge shape of the cylindrical portion is brought into contact with the sheet-like member, and the opening hole is formed on the inner edge of the reinforcing plate. Then, the entire lining is pulled out to the side where the reinforcing plate is disposed through the opening hole, and the opening is formed. If it does so, the diameter of an opening hole (henceforth a mounting hole) becomes the same as the outer diameter of the cylindrical part of a fan main body, or becomes slightly larger than it. The fan is mounted on the fan mounting portion when the flange portion included in the fan main body and the ring-shaped fixing member sandwich the periphery of the mounting hole. At this time, the fan body is inserted into the mounting hole until the flange portion comes into contact with the periphery of the mounting hole.
When the fan main body is inserted into the mounting hole having a diameter that is the same as or slightly larger than the outer diameter of the cylindrical portion of the fan main body, the fan main body may fall out of the mounting hole before the fixing ring is attached. In this case, in order to prevent the fan body from falling off, it is necessary to attach the fixing ring while manually pressing the fan body around the mounting hole, which takes time to install the fan.

In the method for manufacturing the fan mounting portion according to the present invention, in the through hole creating step, a through hole having a diameter smaller than the outer diameter of the fan body is created. The diameter of the through hole is substantially equal to the diameter of the mounting hole. A reinforcing plate is attached along the outer edge of the attachment hole.
Then, when the fan body is inserted into the mounting hole, force is applied to the fan body from the inner edge of the mounting hole. Therefore, the fan main body is difficult to come off from the mounting hole, and it is not necessary to hold the fan main body by hand when attaching the fixing ring.
Therefore, the fan can be easily mounted on the fan mounting portion.

Moreover, the manufacturing method of the fan attachment part which concerns on this invention creates a through-hole by cutting out the inner side of a sewing frame along a sewing frame in a through-hole preparation process. Since the through-hole is formed along the stitching frame, there is no need to create a plurality of cut portions toward the stitching frame (stitching line).

[First embodiment]
A method for manufacturing the fan mounting portion according to the present embodiment will be described with reference to FIGS.
As shown in FIG. 1A, this method for producing the fan attachment portion is a method for producing a fan attachment portion 3 for attaching the fan 2 to the cooling garment 1.

First, the fan attachment portion 3 and the fan 2 attached to the fan attachment portion 3 will be described.
The fan mounting portion 3 is formed on the waist of the back of the cooling garment 1 and is formed one by one in a symmetrical position with respect to the central axis L that bisects the width direction of the bottom of the cooling garment 1. As shown in FIG. 1B, the fan mounting portion 3 includes a surface material 20, a seat member 30, and a reinforcing ring 40 as a reinforcing plate attached between the surface material 20 and the sheet member 30. The A mounting hole 4 is formed in the fan mounting portion 3, and the fan 2 is mounted in the mounting hole 4.

The fan 2 takes in external air and discharges the taken air toward the body. Two fans 2 are provided on the waist of the body. As shown in FIG. 2, the fan 2 has a flange portion 10 formed on the outer periphery of the bottom portion, and includes a fan body 5 having an outer diameter OD and a fixing ring 6 as an annular fixing member. The outer surface 20 and the sheet member 30 are sandwiched between the flange portion 10 and the fixing ring 6, so that the outer surface 20 and the seat member 30 are attached to the attachment hole 4. The fan body 5 is formed with a plurality of air intake ports (not shown) and air discharge ports 7. The fan body 5 includes an axial fan 8 that takes in air outside the cooling garment 1 and discharges the air into the cooling garment 1, and a motor (not shown) that drives the axial fan 8. A locking claw 9 is formed on the side of the fan body 5.
Further, a locking projection 11 is formed on the inner peripheral surface of the fixing ring 6, and the fixing ring 6 and the fan body 5 are fixed by locking the locking projection 11 with the locking claw 9.

Next, the manufacturing method of the fan attachment part which concerns on this embodiment is demonstrated.
In the present embodiment, a method for producing a fan mounting portion of the cooling garment 1 made of fabric will be described. This method of manufacturing the fan mounting portion mainly includes six steps.
The first is a stitching frame creation step in which the stitching frame 41 is created by stitching the sheet member 30 to the front surface 21 which is one surface of the outer material 20. The second is a through-hole creating step for creating a through-hole 42 having substantially the same diameter as the suture frame 41 along the suture frame 41 inside the suture frame 41. The third is a sheet member drawing step in which the attachment member 4 is formed by drawing the sheet member 30 through the through hole 42 to the back surface 22 which is the other surface of the surface material 20 after the through hole creating step. The fourth is a heating and pressurizing process for extending the drawn sheet member 30 by the heating and pressurizing process. The fifth is a reinforcing plate attaching step for attaching a reinforcing ring 40 as a reinforcing plate between the outer material 20 and the sheet member 30 after the sheet member drawing step. And the 6th is a reinforcement board fixing process of sewing the circumference | surroundings of the attachment hole 4 and fixing the reinforcement ring 40 after a reinforcement board attachment process. Hereinafter, each process will be described in detail.

[Suture frame creation process]
In the stitching frame creation step, a stitching frame 41 that is an edge portion of the attachment hole 4 is created.
Specifically, as illustrated in FIG. 3A, a rectangular sheet member 30 is disposed on the front surface 21 of the outer material 20.
Then, as shown in FIG. 3B, a stitching frame 41 is created by stitching the sheet member 30 and the outer material 20 in a circular shape by a commercial sewing machine or hand stitching. The diameter D1 of the stitching frame 41 is preferably made slightly smaller than the outer diameter OD of the fan body 5.
The sheet member 30 is not limited to a rectangular shape, and a polygonal shape or a circular shape may be used.

[Through-hole creation process]
Next, as shown in FIG. 4, the sheet member 30 and the outer material 20 are cut out in a circular shape along the stitching frame 41 so that the inside of the stitching frame 41 is concentric with the stitching frame 41. Through-holes 42 are formed.
The through hole 42 is formed along the suture frame 41, and the diameter D2 of the through hole 42 is substantially the same as the diameter D1 of the suture frame 41 or slightly smaller than the diameter D1 of the suture frame 41.
For example, when the outer diameter OD of the fan body 5 is 90 mm, the diameter D1 of the through hole 41 is 89 mm.

[Sheet member drawing process]
In the sheet member drawing process, the sheet member 30 is pulled out to the back surface 22 of the outer material 20.
Specifically, as shown in FIG. 5, the four corners of the sheet member 30 are pulled in the direction of the through hole 42 (the direction of the arrow). 6A, after pulling the apexes of the four corners of the sheet member 30 to the vicinity of the center of the through hole 42, the sheet member 30 is passed through the through hole 42 as shown in FIG. 6B. The attachment hole 4 is formed by pulling it out to the back surface 22 of the outer material 20. At this time, the back surface 32 of the sheet member 30 appears on the back surface 22 of the outer material 20.
Further, when the sheet member 30 is pulled out to the back surface 22 of the surface material 20, the sheet member 30 is folded back toward the back surface 22 side of the surface material 20 almost along the edge of the stitching frame 41 or the through hole 42.

[Heating and pressing process]
Since the sheet member 30 is a fabric, when the sheet member 30 is pulled out to the back surface 22 of the outer material 20, a swelling (swelling) occurs, and the attachment hole 4 may not have a desired shape.
In the heating and pressurizing treatment step, the drawn sheet member 30 is extended to form the attachment hole 4 having a diameter D3 in a desired shape.
In this heating and pressurizing process, for example, an iron is used, and the sheet member 30 is stretched and flattened by heating and pressurizing from the back surface 32 of the sheet member 30. Then, as shown in FIG. 7, in addition to the formation of the attachment hole 4 having a desired shape, the sheet member 30 is expanded, and the fabric does not rise. Since the sheet member 30 is folded back along the edge of the stitching frame 41 or the through hole 42 to form the attachment hole 4, the diameter D3 of the attachment hole 4 is substantially equal to the diameter D2 of the through hole 42.

[Reinforcement plate installation process]
In the reinforcing plate fixing step, the reinforcing plate is attached around the attachment hole 4 along the outer edge.
In this reinforcing plate fixing process, when the reinforcing ring 40 is attached, it is performed so that a large external force is not applied to the reinforcing ring 40.
As this reinforcing plate, for example, as shown in FIG. 8, a reinforcing ring 40 having an inner diameter D4 can be used. The reinforcing ring 40 is made of a material that has low elasticity and can be sewn. The reinforcing ring 40 can be made of plastic, such as polypropylene. The thickness of the reinforcing ring 40 is designed to be about 0.2 mm, and the inner diameter D4 of the reinforcing ring 40 is designed to be almost the same as the diameter D3 of the mounting hole 4.

The reinforcement ring 40 is attached around the attachment hole 4 as shown in FIG. 9 by inserting the sheet member 30 into the hole of the reinforcement ring 40. As a method for attaching the reinforcing ring 40, for example, the four corners of the sheet member 30 are lifted upward, and the four corners are inserted into the holes of the reinforcing ring 40. Then, the hole of the reinforcing ring 40 moves while contacting the front surface 31 of the sheet member 30, and the reinforcing ring 40 is guided to the periphery of the mounting hole 4.
At this time, the reinforcing ring 40 is disposed between the outer material 20 and the seat member 30. Since the sheet member 30 is expanded in the heating and pressurizing process, after the reinforcing ring 40 is attached, the sheet member 30 returns to the original position, and the shape of the attachment hole 4 is not deformed.
The method for attaching the reinforcing ring 40 is not limited to the above method as long as the reinforcing ring 40 can be disposed around the attachment hole 4 without being deformed. For example, one of the four corners of the sheet member 30 can be inserted into the hole of the reinforcing ring 40 first, and the corners of the other sheet members 30 can be sequentially inserted.

[Reinforcement plate fixing process]
In the reinforcing plate fixing step, the reinforcing ring 40 is fixed around the mounting hole 4.
As shown in FIG. 10, the fixed frame line 45 is formed by sewing the sheet member 30 and the outer material 20 in a circular shape with a commercial sewing machine from above where the reinforcing ring 40 is disposed. Then, the outer frame line 46 is formed by stitching the outer frame of the sheet member 30.
FIG. 11 shows a cross-sectional view taken along the line AA in FIG. From the bottom, the sheet member 30, the reinforcing ring 40, and the outer material 20 are stitched in this order, and the reinforcing ring 40 is fixed around the attachment hole 4.

Next, the effect of the method for manufacturing the fan mounting portion according to the present embodiment will be described.
The diameter D2 of the through hole 42 created in the through hole creation step of the method for producing the fan attachment portion according to the present embodiment is substantially equal to the diameter D3 of the attachment hole 4. Therefore, when the diameter D2 of the through hole 42 is reduced, the diameter D3 of the mounting hole 4 is also reduced. Since the reinforcement ring 40 is attached along the outer edge of the attachment hole 4, the inner diameter D <b> 4 of the reinforcement ring 40 is substantially equal to the diameter D <b> 3 of the attachment hole 4. When the inner diameter D4 of the reinforcing ring 40 is smaller than the outer diameter OD of the fan body 5, when the fan body 5 is attached to the mounting hole 4, the fan body 5 receives a pressing force from the inner edge portion (reinforcing ring 40) of the mounting hole 4. . If it does so, it will become difficult to remove the fan main body 5 from the attachment hole 4, and the state which made the flange part 10 contact | abut the circumference | surroundings of the attachment hole 4 can be maintained.
As a result, the flange portion 10 of the fan main body 5 can be reliably brought into contact with the fan mounting portion 3, and the fan main body 5 can be prevented from being dropped and damaged. Furthermore, since the fixing ring 6 can be attached while maintaining the state in which the flange portion 10 is in contact with the attachment hole 4, the operability of mounting the fan 2 is improved, and the fan 2 can be easily attached to the attachment hole 4. Can be installed.

In the fan mounting portion manufacturing method according to the present embodiment, the reinforcing plate 40 is formed after the mounting hole 4 having a desired shape is formed in order to perform the reinforcing plate mounting process after the sheet member drawing process and the heating and pressurizing process. It is attached. This eliminates the need for pressing the reinforcing ring 40 so that it does not deviate from the predetermined position. This saves the labor of the operator and improves the workability when manufacturing the fan mounting portion 3.
Further, by attaching the reinforcing ring 40 after the sheet member 30 is pulled out to the back surface 22 of the outer surface 20, external force applied to the reinforcing ring 40 when the sheet member 30 is pulled out can be avoided. Therefore, deformation of the reinforcing ring 40 can be prevented, and the fan 2 can be stably mounted in the mounting hole 4.

In the method for manufacturing the fan mounting portion according to the present embodiment, the through hole 42 is created by cutting the inside of the suture frame 41 along the suture frame 41 in the through hole creation step. Since the through hole 42 is formed along the stitching frame 41, it is not necessary to make a plurality of cuts toward the stitching frame 41.
Therefore, the fan mounting portion 3 can be manufactured without taking time and effort by the method for manufacturing the fan mounting portion according to the present embodiment.

  In the conventional technique, a plastic reinforcing ring is attached between the sheet member and the outer surface, and then ironed from above the sheet member to extend and flatten the sheet member. Since the reinforcing ring is made of plastic, the reinforcing ring may be uneven due to heat from the iron. If irregularities are formed in the reinforcing ring, there is a problem that a gap is formed in a part between the flange portion and the fixing ring, and the fan is not stably fixed.

Since the reinforcing ring 40 is attached after the sheet member 30 is stretched with an iron in the heating and pressurizing process, the reinforcing ring 40 is not deformed by the heat of the iron in the heating and pressurizing process. . Then, since the reinforcing ring 40 is not deformed, the fan 2 can be stably mounted in the mounting hole 4 (fan mounting portion 3).
Furthermore, in the method for manufacturing the fan mounting portion of the present embodiment, the reinforcing ring 40 is stitched together with the outer material 20 and the sheet-like member 30 in the reinforcing plate fixing step. By sewing the reinforcing ring 40 together with the outer material 20 and the sheet member 30, the reinforcing ring 40 can be firmly fixed around the mounting hole 4. Therefore, displacement of the reinforcing ring 40 can be prevented, and the fan 2 can be stably mounted in the mounting hole 4.

The reinforcing ring 40 can be fixed together with the outer material 20 and the sheet member 30 without sewing. In this case, in the reinforcing plate attaching step, after being arranged around the attaching hole 4, the fixed frame 45 having an outer diameter larger than the outer diameter of the reinforcing ring 40 is formed. Then, as shown in FIG. 12, the reinforcing ring 40 is fitted and fixed in a region formed between the stitching frame 41 and the fixed frame line 45.
When the reinforcing ring 40 is accommodated in this region, the reinforcing ring 40 is fixed around the attachment hole 4, thereby preventing the reinforcing ring 40 from being displaced from a desired fixing position or falling off.
Further, when the metal reinforcing ring 40 is used as the reinforcing plate, the reinforcing ring 40 may not be sewn. At that time, the metal reinforcing ring 40 can be fixed around the mounting hole 4 by forming the fixed frame wire 45 having an outer diameter larger than the outer diameter of the reinforcing ring 40.

[Second Embodiment]
The manufacturing method of the fan mounting portion according to the present embodiment is mainly different from the manufacturing method of the fan mounting portion of the first embodiment in that the fan mounting portion according to the present embodiment is formed using the surface material 20 and the sheet member 30 in which through holes are formed in advance.
Hereinafter, the difference from the method for producing the fan mounting portion of the first embodiment will be mainly described.

As shown in FIG. 13, a surface material through hole 23 having a diameter smaller than the outer diameter OD of the fan body 5 is formed in the surface material 20 in advance (the diameter of the surface material through hole 23 is D6). On the other hand, a sheet member through hole 33 having the same diameter as that of the outer surface through hole 23 is formed in the sheet member 30 in advance (the diameter of the sheet member through hole 33 is D5). A diameter D6 of the surface through hole 23 and a diameter D5 of the sheet member through hole 33 are formed to be smaller than the outer diameter OD of the fan body 5.
The sheet member 30 is arranged on the front surface 21 of the surface material 20 so that the sheet member through hole 33 and the surface material through hole 23 overlap each other. Thereafter, the sewing frame 41 is created by sewing the periphery of the overlapping through hole 42 along the surface through hole 23 and the sheet member through hole 33 (suture frame creating step).

  After creating the stitching frame 41, the sheet member 30 is pulled out to the back surface 22 of the outer fabric 20 through the through hole 42 (sheet member pulling step). After the sheet member is pulled out, each step is performed in the order of the heating and pressurizing step, the reinforcing plate attaching step, and the reinforcing plate fixing step, and the fan attaching portion 3 is produced. Here, a sheet | seat member extraction process, a heating pressurization process, a reinforcement board attachment process, and a reinforcement board fixing process perform the process similar to 1st embodiment.

In the fan mounting portion manufacturing method of the present embodiment, the sheet member 30 in which the sheet member through hole 33 is formed in advance on the surface material 20 in which the surface material through hole 23 is formed in advance is used as the surface material through hole 23 and the sheet member through hole. Therefore, the positioning of the sheet member 30 on the outer surface 20 is facilitated.
Furthermore, since the surface hole 20 in which the surface material through-hole 23 is formed in advance and the sheet member 30 in which the sheet member through-hole 33 is formed in advance are overlapped, the through-hole 42 can be formed. The through-hole creation process in can be omitted. Therefore, the fan attachment part 3 can be produced in a short time.

Although the present embodiment has been described above, the configuration described in the above embodiment can be selected or changed to other configurations as appropriate without departing from the gist of the present invention. .
For example, in the present embodiment, the example in which the diameter D2 of the through hole 42 is formed to be slightly smaller than the outer diameter OD of the fan main body 5 is shown, but the diameter D2 of the through hole 42 is equal to the outer diameter OD of the fan main body 5. It can be the same or larger than the outer diameter OD of the fan body 5.
Further, in the present embodiment, the example in which the fan 2 in which the flange portion 10 protrudes from the fan main body 5 in the substantially vertical direction is mounted has been described, but the fan in which the flange portion 10 protrudes in the oblique direction from the fan main body 5 is mounted. You can also.

  The reinforcing plate only needs to be formed of a material that does not deform when the fan 2 is mounted in the mounting hole 4, and a metallic reinforcing ring 40 can be used in addition to the plastic reinforcing ring 40. Furthermore, a reinforcement board is not limited to a ring-shaped thing, For example, the some divided | segmented reinforcement board can be used. In this case, since it is not necessary to pass the sheet member 30 through the hole of the ring, the reinforcing plate can be disposed without receiving an external force from the sheet member 30.

  In the present embodiment, the cooling garment 1 is an example in which a fabric material is used. However, for example, a nylon fabric material can also be used. When the material constituting the cooling garment 1 is a material that is not suitable for the heating and pressing step, the heating and pressing treatment step can be omitted. Even when a nylon fabric is used, a heating cloth can be applied with an iron covering from above.

  Further, in the present embodiment, an example in which the reinforcing plate attaching process is performed after the sheet member extracting process is shown, but the reinforcing plate attaching process can be performed before the sheet member extracting process.
