Description

  The present invention relates to a fan mounting having a fan mounting portion for mounting, for example, a fan used in an air circulation mat or air conditioning clothing that evaporates sweat from a human body by circulating air to a sheet-like member such as cloth. It relates to a sheet with a part.

  In recent years, air-flowing mats and air-conditioning clothes that evaporate sweat from a human body by circulating air have been put into practical use (see, for example, Patent Documents 1 and 2). For example, the air-conditioning garment is sewn with a material that does not easily leak air, and two fan attachment portions for attaching a fan are provided below the rear side of the air-conditioning clothing. When the fan is attached to the fan mounting portion and the fan is operated, a large amount of outside air is taken into the air-conditioning garment from the fan. The taken-in outside air flows upward in parallel with the human body and is discharged, for example, from around the collar or cuffs. While the outside air circulates in the air-conditioning garment, the sweat generated from the human body can be evaporated, and the temperature of the body surface can be lowered by the heat of vaporization when it evaporates (see, for example, Patent Document 3).

  Next, the manufacturing method of an air-conditioning garment is demonstrated. Here, consider the case where the air-conditioning suit is a work-use air-conditioning suit. Prior to the description, a general method for manufacturing work clothes will be briefly described. In order to manufacture a general work clothes, first, the fabric is cut according to the pattern corresponding to the work clothes to be manufactured, and the cloth parts of each part are produced. In the case of general work clothes, there are more than a dozen cloth parts. Next, a fastener, a button, etc. are attached to the cloth part of a predetermined | prescribed site | part. Then, a general work clothes is completed by sewing cloth parts together.

  The point that the manufacturing method of the air-conditioning garment is greatly different from the manufacturing method of the general work clothes includes a step of providing a fan mounting portion for mounting the fan on the cloth part of the portion corresponding to the lower side of the rear side of the air-conditioning garment. Is a point. Here, a sheet provided with a fan attachment portion on a sheet-like member such as cloth or cloth part is a sheet with a fan attachment portion. There are two main methods for manufacturing air-conditioning clothing. One of them is a method in which the fan mounting portion is directly formed on the cloth part itself corresponding to the lower part of the rear side portion of the air-conditioning garment. Another method is to prepare a sheet with a fan mounting portion in which a fan mounting portion is provided on a sheet-like member such as a small cloth instead of a cloth part of the air conditioning clothing, and use this as the rear side portion of the air conditioning clothing. It is a method of attaching to the cloth part of the site | part corresponded below by sewing. Hereinafter, for the sake of convenience, the former method is referred to as a self-sheet method, and the latter method is referred to as another sheet method.

  In the self-sheet method, it is necessary to fabricate the fan mounting part on the cloth part at the sewing site, but since the cloth part used for the air-conditioning clothing itself is cut as the cloth part, the discomfort on the appearance is Few. On the other hand, in the method using the other sheet method, for example, a sheet with a fan attachment portion can be mass-produced at a place different from the sewing site using a square cloth having an appropriate size according to the size of the fan. For this reason, by using such a mass-produced seat with a fan mounting portion, it becomes possible for a general garment manufacturer who does not have equipment and skills necessary for processing the fan mounting portion to manufacture air-conditioning clothing. Here, from an economic point of view, it is not rational to use the cloth used for the air-conditioning garment itself as the material cloth, and it is desirable to use a cloth made of another material. In this case, since the cloth used for the air-conditioning garment and the cloth used for the sheet with the fan mounting portion are different materials, an uncomfortable appearance may occur, but it is advantageous from the viewpoint of manufacturing cost. .

  Conventionally, in most air-conditioning clothes, fans are attached at two locations on the rear side. However, the waist is too cold, or the fan may get in the way when riding in an automobile or the like, and it is often desired to attach the fan to a portion directly beside the trunk portion. FIG. 12 is a schematic side view of a general work clothes. Usually, in general work clothes, as shown in FIG. 12, the cloth parts 200 are stitched together at a position just beside. Here, the stitches 210 formed by the stitching are indicated by broken lines. In the air-conditioning garment, the cloth parts 200 are stitched together at the position just beside the general work clothes, and therefore it is difficult to produce a fan mounting portion at the stitched portion by a method using the self-seat method. . On the other hand, in the method using the other sheet method, since the sheet with the fan attachment portion can be easily attached across the adjacent cloth parts 200, it is possible to attach the fan to the position just beside.

  Even if air-flowing mats or air-conditioning suits are manufactured using either the self-seat method or the other-seat method, air from the fan mounting portion is used to increase the air-conditioning effect of the fans used for it. It is necessary to securely attach the fan to the sheet-like member so as not to leak. On the other hand, when washing air circulation mats, air-conditioning clothes, etc., it is necessary for the user to be able to easily remove the fan from the sheet-like member.

  For this reason, it is desirable to use a fan having the structure shown in FIG. Such a fan includes a fan main body and an annular locking member for attaching the fan main body to a sheet-like member. The fan body includes a hollow cylindrical portion and a flange portion that protrudes from the upper end of the cylindrical portion in a direction substantially perpendicular to the side surface of the cylindrical portion. The annular locking member is inserted outside the cylindrical portion, and the sheet-shaped member around the opening hole formed in the sheet-shaped member is formed by the back surface of the flange portion and the end surface facing the flange portion of the annular locking member. The fan is attached to the sheet-like member by sandwiching the end portion and engaging the engaging piece provided on the tubular portion with the protrusion provided on the annular engaging member.

  Since the sheet-like member used for air-conditioning clothing and the like expands and contracts, using a fan mounting part that simply has an opening hole for attaching the fan to the sheet-like member exerted a strong force on the fan. Sometimes the fan is easily detached from the sheet-like member. For this reason, Patent Document 2 uses a fan mounting portion that includes an opening hole for mounting the fan and a non-stretchable material provided at the end of the sheet-like member around the opening hole. Has been proposed. Specifically, the fan mounting portion including this non-stretchable material is manufactured as follows. That is, first, after forming a hole at a predetermined location of the sheet-like member, the portion of the sheet-like member around the hole is folded back. Next, a ring-shaped non-stretchable material is inserted between the sheet-like members that are overlapped by the folding. Thereafter, a fabric is applied to the portion of the sheet-like member into which the non-stretchable material has been inserted from the back side, and the sheet-like member and the fabric are sewn with a thread at the portion. Thus, an opening hole is formed and a non-stretchable material is sewn around the opening hole.

Japanese Patent No. 4399765 Republished Patent No. WO2006 / 009108 JP 2005-54299 A

  However, in the method of manufacturing the fan mounting portion as described above, the portion of the sheet-like member around the hole is folded back and the non-stretchable material is inserted between the overlapping sheet-like members by the folding. At that time, it was difficult to arrange the opening hole into an accurate circular shape, and the work was troublesome. In addition, when a cloth is applied to the portion of the sheet-like member into which the non-stretchable material is inserted from the back side and the sheet-like member and the fabric are sewn with a thread in the portion, the shape of the opening hole is carefully maintained. This work is not only troublesome, but it can only be done by skilled personnel, and is difficult for beginners.

  The present invention has been made based on the above circumstances, and an object of the present invention is to provide a sheet with a fan attachment portion that can easily produce a fan attachment portion on a sheet-like member.

  To achieve the above object, the present invention provides a fan body having a cylindrical portion and a protruding portion provided in the cylindrical portion so as to protrude in a direction substantially perpendicular to the side surface of the cylindrical portion, and the cylindrical shape A seat with a fan mounting portion for mounting a fan comprising a locking member mounted on the fan body in a state of being inserted to the outside of the portion and facing the protruding portion, and an opening hole through which the tubular portion of the fan passes And an opening having substantially the same shape as the outer edge of the fan cylindrical portion, and one of the front and back surfaces is at the end of the sheet-like member around the opening hole. A flat annular reinforcing means that is fixed and has an inner surface exposed and is not stretchable. The cylindrical portion is inserted into the opening of the reinforcing means, and the locking member is attached to the fan body. The end of the sheet-like member and the end of the reinforcing means around Less by sandwiching the end portion of the reinforcing means between the projecting portion and the locking member, in which the fan, characterized in that is attached.

  With the above configuration, in the present invention, one of the front surface and the back surface of the reinforcing means is fixed to the end portion of the sheet-like member around the opening hole. For this reason, when producing a fan mounting portion for mounting a fan on a sheet-like member, the sheet-like member is folded back as in the prior art, and a reinforcing means is inserted into the folded-up sheet-like member and the sheet of that portion is placed. Since it is not necessary to apply the backing cloth to the sheet-like member, the fan mounting portion can be easily produced on the sheet-like member. Further, since the end portion of the sheet-like member around the opening hole is not expanded or contracted by the non-stretchable reinforcing means, the end portion can be reinforced, so that even between the fan and the reinforcing means, or the fan Even if a strong force is applied between the fan and the sheet-like member, the fan is not easily detached from the fan mounting portion. Furthermore, if the inner surface of the reinforcing means is exposed, and only one of the front and back surfaces of the reinforcing means is fixed to the end of the sheet-like member, the sheet of each surface of the reinforcing means Surfaces other than the one surface fixed to the end of the member are exposed without being covered with the sheet member, and the inner surface of the fan mounting portion for mounting the fan becomes the inner surface of the reinforcing means. For this reason, the shape and size of the fan mounting portion can be formed with high accuracy by accurately manufacturing the shape and size of the reinforcing means.

  In the sheet with a fan attachment portion according to the present invention, the fan attachment portion can be easily produced on the sheet-like member. Even if a strong force is applied between the fan and the reinforcing means or between the fan and the sheet-like member, the fan does not easily come off from the seat mounting portion.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[First embodiment]
First, a first embodiment of the present invention will be described with reference to the drawings. 1A is a schematic front view of a sheet with a fan mounting portion according to the first embodiment of the present invention, FIG. 1B is a schematic rear view of the sheet with a fan mounting portion, and FIG. It is an AA arrow direction outline partial sectional view of a sheet with an attaching part. FIG. 2A is a schematic side view showing a state when a fan used in an air circulation mat, air conditioning clothing, or the like is inserted into the opening hole of the sheet with the fan mounting portion of the first embodiment, and FIG. Fig. 2 is a schematic side view of an annular locking member in the fan, and Fig. 2C is a schematic side view showing a state when the fan is attached to the fan attachment portion. FIG. 3 is a schematic partial sectional view showing a state in which the fan is attached to the fan attachment portion.

  The sheet with a fan mounting portion of the first embodiment has a predetermined fan mounting portion for mounting a fan used for an air flow mat or air conditioning clothing that evaporates sweat from a human body by circulating air. It is provided in the shaped member. As shown in FIG. 1, the fan-attached sheet 1 includes a sheet-like member 10, an opening hole 20, and a flat annular reinforcing member (reinforcing means) 30 that is not stretchable. The sheet-like member 10 is a target on which a fan attachment portion is provided. The fan attachment portion includes an opening hole 20, an end portion of the sheet-like member 10 around the opening hole 20, and a reinforcing member 30.

  The sheet 1 with a fan attachment portion of the first embodiment is used when air-conditioning clothing or the like is manufactured by a method using a self-seat method. For this reason, as the sheet-like member 10, what cut | judged the cloth used for air-conditioning clothing itself is used. The material of the sheet-like member 10 is, for example, a normal woven fabric. The sheet-like member 10 has a front and back. That is, the surface located on the front side of the air-conditioning garment manufactured using the sheet 1 with the fan attachment portion is the surface of the sheet-like member 10, and the surface located on the back side of the air-conditioning garment is the back surface of the sheet-like member 10. Further, following the positional relationship between the front and back surfaces of the sheet-like member 10, in each part, the surface on the side having the same positional relationship as the surface of the sheet-like member 10 is the front surface, and the side having the same positional relationship as the back surface of the sheet-like member 10. The surface is also referred to as the back surface.

  Now, the fan 100 used for an air-flowing mat or air-conditioning clothing will be briefly described. As shown in FIG. 2, the fan 100 includes a fan main body 110 that houses a motor and a propeller, and an annular locking member 120 that is attached to the fan main body 110. The fan main body 110 includes a tubular portion 111 and a flange portion 112 that protrudes from the upper end of the tubular portion 111 in a direction substantially perpendicular to the side surface of the tubular portion 111. The outer shape of the cross section when the cylindrical portion 111 is cut by a plane perpendicular to the central axis is circular. Here, the outer diameter F of the cylindrical part 111 is 64.5 mm. The locking member 120 is a dedicated tool for attaching the fan main body 110 to the fan attachment portion of the seat 1 with the fan attachment portion. Two locking claws 113 are provided on the cylindrical portion 111 of the fan main body 110. On the other hand, a projection (not shown) is provided on the inner surface of the locking member 120 to engage with each locking claw 113 and fix the locking member 120 to the outer surface of the cylindrical portion 111. . For this reason, the locking member 120 can be easily attached to the fan main body 110 in a state of facing the flange portion 112 by inserting the locking member 120 outside the cylindrical portion 111 and engaging with the fan main body 110. Can do.

  The opening hole 20 in the sheet 1 with the fan attachment portion is for passing the tubular portion 111 of the fan 100 and is formed at a predetermined position of the sheet-like member 10. In the first embodiment, as shown in FIGS. 1A and 1B, the shape of the opening hole 20 is circular. The diameter of the opening hole 20 is substantially the same as or larger than the outer diameter F of the cylindrical portion 111. In the first embodiment, the opening hole 20 having substantially the same diameter as the outer diameter F of the cylindrical portion 111 is formed in the sheet-like member.

  The reinforcing member 30 is a flat annular member having an opening having substantially the same shape as the outer edge of the cylindrical portion 111 of the fan 100. In the first embodiment, as shown in FIG. 1B, the reinforcing member 30 has an annular shape, and has an inner diameter (diameter of the opening) that is substantially the same as the outer diameter F of the cylindrical portion 111. . Therefore, the inner diameter of the reinforcing member 30 and the diameter of the opening hole 20 are substantially the same. As the material of the reinforcing member 30, a material that can be washed and does not have much stretchability and can be sewn is used. Specifically, any material of plastic, resin-impregnated cloth, artificial leather, and non-stretchable rubber can be used. In particular, in the first embodiment, the reinforcing member 30 is made of polypropylene and has a thickness of 0.5 mm, an inner diameter of 65 mm, an outer diameter of 73 mm, and a width of 4 mm. In fact, the reinforcing member 30 can be easily manufactured with high accuracy by punching a polypropylene sheet. The reinforcing member 30 is opaque.

  The reinforcing member 30 is fixed to the end of the sheet-like member 10 around the opening hole 20 on the back surface of the sheet-like member 10. That is, the surface of the reinforcing member 30 is fixed to the end portion of the sheet-like member 10 around the opening hole 20. Specifically, the reinforcing member 30 is fixed to the sheet-like member 10 by stitching the reinforcing member 30 and the end of the sheet-like member 10 around the opening hole 20 with a thread 40. Here, in FIG. 1 (a), (b), the seam 41 formed by this sewing operation | work is shown with the broken line. Further, the reinforcing member 30 and the sheet-like member 10 are sewn into a circle in the vicinity of the approximate center of the reinforcing member 30. At this time, surfaces other than the surface fixed to the end of the sheet-like member 10 among the surfaces of the reinforcing member 30 are exposed without being covered with the sheet-like member 10. Therefore, as shown in FIG. 1C, the inner side surface 31 of the reinforcing member 30 is exposed.

  Here, the relationship between the inner diameter / outer diameter of the reinforcing member 30 and the diameter of the opening hole 20 will be described. In general, the diameter of the opening hole 20 is substantially the same as or larger than the inner diameter (diameter of the opening) of the reinforcing member 30. When the diameter of the opening hole 20 is larger than the inner diameter of the reinforcing member 30, the outer diameter of the reinforcing member 30 must be larger than the diameter of the opening hole 20. This is because it is necessary to attach the reinforcing member 30 to the end portion of the sheet-like member 10 around the opening hole 20. As described above, in the first embodiment, the opening member 20 having a diameter substantially the same as the inner diameter of the reinforcing member 30 is formed in the sheet-like member 10. Thus, when the reinforcing member 30 is fixed to the end portion of the sheet-like member 10 around the opening hole 20, the entire lower surface (front surface) of the reinforcing member 30 is the opening hole as shown in FIG. The reinforcing member 30 cannot be seen from the front side of the sheet-like member 10 as shown in FIG.

  By the way, it is necessary to reinforce the cloth on the edge of the sheet-like member 10 around the opening hole 20. For example, when two woven fabrics are stitched, a force in the direction of peeling the two woven fabrics may be applied to the two woven fabrics during use. Sufficient stitching strength corresponding to the above is required. In fact, if the two woven fabrics are simply overlapped and stitched, if a force is applied in the direction of peeling the two woven fabrics at the stitched portions, the yarn located on the edge side from the stitched portions. The two woven fabrics are easily peeled off. As a general method for preventing this, for example, after a treatment is performed to fold the edge portion of each of the two woven fabrics into a double shape, the doubled portions are overlapped to overlap each other. There is a method of stitching a piece of woven fabric. Even if one of the objects to be sewn is a cloth and the other is made of a material that does not fray, the cloth needs to be reinforced. Therefore, the cloth reinforcing process includes a process for ensuring that the two members after stitching have sufficient strength when two members, at least one of which is made of cloth, are sewn, and a thread for the cloth members. It means both processing to prevent fraying.

  In the sheet 1 with a fan mounting portion of the first embodiment, as shown in FIG. 1C, an anchor is provided on the back surface of the sheet-like member 10 and on the portion X of the sheet-like member 10 around the opening hole 20. The fabric is reinforced using the effect. Specifically, by welding a predetermined resin to the portion X of the sheet-like member 10 around the opening hole 20, the strength of the portion X of the sheet-like member 10 is increased and the fraying of the yarn is prevented. Yes. And after aligning the position of the inner edge of the reinforcement member 30 and the opening hole 20 correctly, as shown to Fig.1 (a), (b), the sheet-like member 10 around the reinforcement member 30 and the opening hole 20 is shown. The ends are integrated with a thread 40 in a circular shape.

  In order to attach the fan 100 to the fan-attached seat 1 according to the first embodiment, first, the tubular portion 111 of the fan main body 110 is inserted into the opening of the reinforcing member 30, and as shown in FIG. The lower surface of the flange 112 is in contact with the edge of the sheet-like member 10 around the opening hole 20. Next, by inserting the locking member 120 to the outside of the cylindrical portion 111, as shown in FIG. 3, the end portion of the sheet-like member 10 and the end portion of the reinforcing member 30 around the opening hole 20 are connected to the flange portion. 112 is sandwiched between the lower surface of 112 and the upper surface of the locking member 120, and the latching claw 113 provided on the tubular portion 111 and the protrusion provided on the locking member 120 in the sandwiched state. Are engaged with each other to attach the locking member 120 to the fan main body 110. Thus, as shown in FIG. 2C, the fan 100 is attached to the fan attachment portion. Here, when the fan 100 is attached to the fan attachment portion, the reinforcing member 30 and the locking member 120 are in direct contact with each other, and the inner side surface 31 of the reinforcing member 30 is in direct contact with the outer side surface of the tubular portion 111. Yes.

Next, the manufacturing method of the sheet | seat 1 with a fan attachment part of 1st embodiment is demonstrated.
The manufacturing method of the sheet | seat 1 with a fan attachment part of 1st embodiment is the 1st process of performing the reinforcement | strengthening process of the cloth to the predetermined part of the sheet-like member 10, and the 2nd process of forming the opening hole 20 in the sheet-like member 10. And the third step of stitching the reinforcing member 30 and the sheet-like member 10 together. FIG. 4 is a diagram for explaining the first step and the second step in the method for producing the sheet 1 with a fan attachment portion of the first embodiment, and FIG. 5 shows the third step in the method for producing the sheet 1 with a fan attachment portion. It is a figure for demonstrating.

  When performing a 1st process, the sheet | seat 60 for circular reinforcement processing as shown to Fig.4 (a) is prepared. The reinforcing treatment sheet 60 is made of polypropylene and has a diameter of 75 mm and a thickness of about 0.2 mm. In the first step, first, as shown in FIG. 4B, the reinforcing treatment sheet 60 is disposed under the sheet-like member 10.

  Next, as shown in FIG. 4 (b), the horn 70 for an ultrasonic welder having a ring-shaped pressing surface is set so that its own central axis coincides with the central axis of the reinforcing treatment sheet 60. And press against the sheet-like member 10. Here, the inner diameter of the horn 70 for an ultrasonic welder is smaller than the outer diameter F of the cylindrical portion 111. On the other hand, the outer diameter of the horn 70 is desirably larger than the diameter of the reinforcing treatment sheet 60. Thereafter, when the horn 70 is ultrasonically vibrated, a portion corresponding to the horn 70 in the reinforcing treatment sheet 60 is melted or softened, and bites into the back surface of the sheet-like member 10. Thus, the polypropylene resin is welded to a predetermined portion of the back surface of the sheet-like member 10, thereby increasing the strength of the portion. In FIG. 4C, when the sheet-like member 10 is viewed from the back side, the ring-shaped portion X to which the polypropylene resin has been welded, that is, subjected to the reinforcing treatment, is indicated by hatching.

  Next, in the second step, as shown in FIG. 4 (d), a portion subjected to a strengthening process using a cutting machine having a cutting blade having a diameter substantially the same as the outer diameter F of the cylindrical portion 111. The opening hole 20 is opened in the sheet-like member 10 by cutting X. Thereby, the width of the portion X is narrowed. Here, since the polypropylene resin is welded to the reinforced portion X, the yarn located on the cut surface is not frayed.

  Next, in the third step, a sewing operation is performed between the reinforcing member 30 and the sheet-like member 10 using a sewing machine. In the sewing operation in the third step, a predetermined sewing jig is used. The sewing jig 81 is formed in a substantially cylindrical shape as shown in FIG. Here, the outer diameter of the sewing jig 81 is substantially the same as the inner diameter of the reinforcing member 30. Further, the upper part of the sewing jig 81 is chamfered. In this third step, first, as shown in FIG. 5B, a sewing jig 81 is placed on the table 82 of the sewing machine. Next, the reinforcing member 30 is inserted into the sewing jig 81. Thereafter, the sheet-like member 10 is inserted into the sewing jig 81 with the surface on which the polypropylene resin is welded down in the first step. Thus, the reinforcing member 30 and the sheet-like member 10 are overlapped. Next, as shown in FIG. 5 (b), the reinforcing member 30 and the sheet-like member 10 are attached using the sewing machine in a state where the presser column 83 of the sewing machine is applied to the side wall of the sewing jig 81 at a right angle. Sew in a circle. Thus, the sheet 1 with a fan attachment portion of the first embodiment is produced.

  In the first step, the case where the cloth is reinforced by welding the resin to the sheet-like member 10 has been described. For example, a commercially available fray-fastening agent is applied to the sheet-like member 10. The cloth may be reinforced. In addition, for example, when the sheet-like member 10 is laminated, like a material used for rainwear, has no fraying, and has sufficient strength against stitching, etc. The first step of applying a cloth reinforcing process to a predetermined portion of the sheet-like member 10 can be omitted.

  In the sheet with the fan mounting portion of the first embodiment, the reinforcing member is fixed to the end of the sheet-like member around the opening hole, so that when the sheet with the fan mounting portion is manufactured, , It is not necessary to fold the sheet-like member, put a reinforcing member into the folded sheet-like member, and apply a backing cloth to the sheet-like member at that part, so the fan mounting part can be easily attached to the sheet-like member Can be produced. Further, the end of the sheet-like member around the opening hole can be reinforced by the non-stretchable reinforcing member so that the end can be reinforced, so that even between the fan and the reinforcing member or the fan Even if a strong force is applied between the sheet mounting member and the sheet-like member, the fan does not easily come off from the seat mounting portion. Further, among the surfaces of the reinforcing member, the surfaces other than one surface fixed to the end of the sheet-like member are exposed without being covered with the sheet-like member, so that the inner surface of the fan mounting portion is the reinforcing member. Therefore, if the shape and size of the reinforcing member are manufactured with high accuracy, the shape and size of the fan mounting portion can be formed with high accuracy.

  Further, in the seat with the fan mounting portion of the first embodiment, the entire surface of the reinforcing member is completely covered with the sheet-like member, so that when the fan is removed from the fan mounting portion, the reinforcing member is externally attached. Since it cannot be seen, the appearance of air-conditioning clothes etc. will not deteriorate. Furthermore, the portion of the sheet-like member on the back surface of the sheet-like member around the opening hole is subjected to a fabric reinforcement process using an anchor effect, thereby effectively preventing fraying of the yarn in the portion. be able to. Further, the reinforcing member can be firmly attached to the sheet-like member by stitching the reinforcing member and the portion of the sheet-like member subjected to the reinforcing treatment.

  In the first embodiment, an opening hole having a diameter substantially the same as the inner diameter of the reinforcing member is formed in the sheet-like member, and the entire surface of the reinforcing member is covered with the sheet-like member. As described above, the diameter of the opening hole may be larger than the inner diameter (diameter of the opening) of the reinforcing member. FIG. 6 is a schematic partial sectional view showing a state in which the fan is attached to the fan attachment portion in the modification of the first embodiment. In this case, as shown in FIG. 6, only a part of the upper surface (surface) of the reinforcing member 30 is covered with the sheet-like member 10, and when the fan 100 is attached to the fan attachment portion, the opening is opened. Only the end of the reinforcing member 30 around the hole 20 is sandwiched between the lower surface of the flange portion 112 and the upper surface of the locking member 120.

[Second Embodiment]
Next, a sheet with a fan mounting portion according to the second embodiment of the present invention will be described. FIG. 7A is a schematic rear view of a sheet with a fan mounting portion according to the second embodiment of the present invention, and FIG. 7B is a schematic partial cross-sectional view in the direction of arrow BB of the sheet with a fan mounting portion. . In the second embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 7, the sheet 1 a with a fan attachment portion of the second embodiment includes a sheet-like member 10 a, an opening hole 20, and a flat annular reinforcing member (reinforcing means) 30 a that is not stretchable. This sheet 1a with a fan attachment part is used when manufacturing air-conditioning clothes etc. mainly by the method by a self-seat system. The difference between the sheet 1a with a fan attachment portion of the second embodiment and the sheet 1 with a fan attachment portion of the first embodiment is performed by a general sewing operation as a cloth reinforcement process on the sheet-like member 10a. A fray-fastening point is adopted, and a transparent member is used as the reinforcing member 30a. Other configurations are the same as those of the first embodiment.

  Specifically, as shown in FIG. 7B, a plurality of cuts 13 are made at the end of the sheet-like member 10 a around the opening hole 20, and the sheet-like member 10 a into which the cuts 13 are put. The part is folded back. Here, the portion of the sheet-like member 10a in which the cut 13 is made is also referred to as a “cut portion 14”. And each notch part 14 and the part of the sheet-like member 10a which overlaps with it are adhere | attached. Thus, in 2nd embodiment, the edge part of the sheet-like member 10a in the circumference | surroundings of the opening hole 20 is made double, the strength is raised, and the fraying of a thread | yarn is prevented. Further, as shown in FIG. 7 (c), the reinforcing member 30 a is the back surface of the sheet-like member 10 a, and is provided at the end portion (double portion) of the sheet-like member 10 a around the opening hole 20. It is fixed.

Next, the production method of the sheet 1a with a fan attachment part of 2nd embodiment is demonstrated.
The manufacturing method of the sheet | seat 1a with a fan attachment part of 2nd embodiment is the 1st process of forming the opening hole 20 and the notch 13 in the sheet-like member 10a, and performs the reinforcement | strengthening process of the cloth to the predetermined part of the sheet-like member 10a. It consists of two steps and a third step of stitching the reinforcing member 30a and the sheet-like member 10a together. FIG. 8 is a diagram for explaining the first step and the second step in the method for producing the sheet 1a with a fan attachment portion of the second embodiment. Here, FIG.8 (d) is a CC sectional view schematic sectional drawing in FIG.8 (c).

  In the first step, using an exclusive cutting machine, as shown in FIG. 8A, an opening hole 20 is opened at a predetermined location of the sheet-like member 10a, and the end of the sheet-like member 10a around the opening hole 20 is formed. A number of cuts 13 are made in the part. Here, in the first step, a circular hole having a diameter of 55 mm is formed as the opening hole 20. A large number of the cuts 13 are radially entered into the ring-shaped portion of the sheet-like member 10 surrounded by the circle C1 having a diameter of 55 mm and the circle C2 having a diameter of 65 mm, which are the edges of the opening hole 20. This ring-shaped portion is composed of a large number of cut portions 14 divided by cuts 13.

  The above-mentioned numerical value of 65 mm, which is the length of the notch 13 to be inserted into the sheet-like member 10, is a numerical value corresponding to the outer diameter 64.5 mm of the cylindrical portion 111 of the fan 100. However, since the sheet-like member 10 used for an air-conditioning garment has elasticity, the above numerical value does not define the exact length of the cut 13. Similarly, in the present specification, numerical values described for the dimensions and the like of the sheet-like member 10 do not prescribe strict values.

  Next, the second step is performed. When performing the work in the second step, a ring-shaped bonding sheet 15 is prepared. The bonding sheet 15 is made of polypropylene, and has an inner diameter of 65 mm, an outer diameter of 75 mm, and a thickness of 0.2 mm. In the second step, first, the sheet-like member 10a is placed on the ironing board with its back surface facing up. And as shown in FIG.8 (b), the sheet | seat 15 for adhesion | attachment is arrange | positioned on the sheet-like member 10a so that its own central axis may correspond with the central axis of the opening hole 20. FIG. Thereafter, as shown in FIG. 8C, the cut portion 14 in the sheet-like member 10 a is folded back onto the adhesive sheet 15. At this time, if an iron is used and each notch portion 14 is folded and pressed with the tip of the iron, the folds can be creased, so that each notch portion 14 returns to its original state. Can be reliably prevented. In addition, when turning back the notch part 14, you may make it carry out mechanically using not only an iron but a dedicated apparatus.

  Next, the horn 70 for an ultrasonic welder used in the first embodiment is pressed onto the portion of the sheet-like member 10 a corresponding to the cut-in cut portion 14. Then, when the horn 70 is ultrasonically vibrated, the adhesive sheet 15 is melted and overlapped with each cut portion 14 by the molten adhesive sheet (polypropylene resin) as shown in FIG. The sheet-like member 10a is adhered. As described above, since the end portion of the sheet-like member 10a around the opening hole 20 is doubled, the strength of the end portion can be increased and the fraying of the yarn can be prevented. Moreover, since each notch part 14 was turned back in the 2nd process, the diameter of the opening hole 20 is expanded from 55 mm to 65 mm.

  Note that, as described above, the polypropylene adhesive sheet 15 is used as an adhesive for adhering the cut portion 14 to the portion of the sheet-like member 10a overlapping therewith. Therefore, the adhesive sheet is not limited to the polypropylene adhesive sheet 15, and various materials can be used as long as the sheet exhibits an adhesive effect. In this case, the bonding method is not limited to the method using ultrasonic welding, and a bonding method according to the material used, such as heat welding using a heater, can be used.

  Next, in the third step, a sewing operation is performed between the reinforcing member 30a and the sheet-like member 10 using a sewing machine. The suturing operation in the third step is the same as the third step in the first embodiment. Here, in Fig.7 (a), the circular shaped seam 41 formed by this sewing operation | work is shown with the broken line. In this way, a sheet 1a with a fan attachment portion as shown in FIG. 7 is produced.

  The sheet with a fan attachment portion of the second embodiment has substantially the same operations and effects as the sheet with a fan attachment portion of the first embodiment. However, when producing the sheet with a fan mounting portion of the second embodiment, it is necessary to perform an operation of folding and bonding the end of the sheet-like member around the opening hole. Comparing the sheet with the fan mounting part of the embodiment and the sheet with the fan mounting part of the first embodiment, it can be said that the latter can be produced more easily.

  In the second embodiment, a transparent member is used as the reinforcing member, but frankly, it is desirable to use an opaque member as the reinforcing member. This is because when the reinforcing member is transparent, when the fan mounting portion is viewed from the back side of the air-conditioning garment, the state where the cut portion is folded back is visible, and the appearance is not good.

[Third embodiment]
Next, a sheet with a fan mounting portion according to a third embodiment of the present invention will be described. FIG. 9A is a schematic rear view of a sheet with a fan attachment portion according to the third embodiment of the present invention, and FIG. 9B is a view when the sheet with a fan attachment portion is attached to a predetermined cloth part of an air-conditioning garment. It is a figure for demonstrating a state. Here, FIG.9 (b) has shown the state when it sees from the back side of an air-conditioning clothing. In the third embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 9A, a sheet 1b with a fan attachment portion of the third embodiment includes a sheet-like member 10b, an opening hole 20, a flat annular reinforcing member (reinforcing means) 30 that does not have elasticity. Is provided. The difference between the sheet 1b with a fan attachment portion of the third embodiment and the sheet 1 with a fan attachment portion of the first embodiment is that the sheet 1b with a fan attachment portion manufactures air-conditioning clothing and the like by a method using another sheet method. This is the point used. Specifically, in the first embodiment, since the cloth member used for the air-conditioning clothing itself is used as the sheet-like member 10, for example, the size of the sheet-like member 10 is considerably larger than the size of the fan mounting portion. In the third embodiment, as the sheet-like member 10b, as shown in FIG. 9 (a), a member formed in a square shape that is slightly larger than the size of the fan mounting portion is used. Other configurations are the same as those of the first embodiment.

  Thus, in 3rd embodiment, since the sheet | seat 1b with a fan attachment part is used for manufacture of the air-conditioning clothing etc. by the method by another sheet system, it is a sheet | seat with a fan attachment part in a place different from a sewing site. 1b can be mass-produced. For this reason, by using such a mass-produced sheet 1b with a fan mounting portion, a general garment manufacturer who does not have the facilities and skills necessary for processing the fan mounting portion can manufacture air-conditioning clothing and the like. Become.

  Specifically, when manufacturing the air-conditioning garment using the sheet 1b with a fan attachment portion of the third embodiment, first, the sheet-like member 10b is placed at a predetermined position of the cloth part of the air-conditioning garment corresponding to the attachment part of the fan. Make a square hole with a size slightly smaller than the size of. Thereafter, as shown in FIG. 9B, the sheet 1b with the fan attachment portion is attached to the cloth part 200 by sewing the end of the sheet-like member 10b to the portion of the cloth part 200 around the hole. Here, in FIG.9 (b), the square-shaped seam 42 formed by this sewing operation | work is shown with the broken line. In addition, what attached the sheet | seat 1b with a fan attachment part of 3rd embodiment to the cloth part 200 is considered as a sheet | seat with a fan attachment part, and it may be used for manufacture of an air-conditioning garment etc. by the method by a self-sheet system. Good.

  The sheet with a fan mounting portion of the third embodiment exhibits substantially the same operations and effects as the sheet with a fan mounting portion of the first embodiment.

  By the way, normally, in the air-conditioning garment, the cloth parts 200 are stitched together at a position just beside the general work clothes shown in FIG. 12, and in the self-seat method, a fan is placed at the position beside the air-conditioning garment. It is difficult to produce the mounting portion. On the other hand, in the method using the other sheet method, the sheet 1b with the fan attachment portion can be easily attached across the adjacent fabric parts 200. Therefore, when the sheet with the fan mounting portion of the third embodiment is used, the fan can be provided at a position directly beside the air-conditioning clothing. Thereby, for example, it can be avoided that the fan gets in the way when getting on an automobile or the like.

  In the third embodiment, the case where the sheet-like member is formed in a square shape has been described. However, the shape of the sheet-like member is not limited to the square shape, and may be a triangular shape, a circular shape, or the like.

(Modification of the third embodiment)
Next, a modification of the third embodiment will be described. FIG. 10A is a schematic back view of a sheet with a fan mounting portion, which is a modification of the third embodiment, and FIG. 10B is a schematic partial cross-sectional view in the direction of arrow DD of the sheet with a fan mounting portion. .

  As shown in FIG. 10, a sheet 1c with a fan attachment portion, which is a modification of the third embodiment, includes a sheet-like member 10c, an opening hole 20, and a flat annular reinforcing member (reinforcing means) 30c that is not stretchable. With. In this modification, the material of the sheet-like member 10c and the material of the reinforcing member 30c are the same, and the sheet-like member 10c and the reinforcing member 30c are integrally molded. It can be considered that the surface of the reinforcing member 30c is also fixed to the end portion of the sheet-like member 10c around the opening hole 20 in the fan-attached seat 1c. Specifically, plastic can be used as the material of the sheet-like member 10c and the material of the reinforcing member 30c. In this case, an integrally molded product of the sheet-like member 10c and the reinforcing member 30c can be easily produced by a method such as injection molding.

  In addition, about the said plastic, if the presence of the thickness which can make compatible the intensity | strength requested | required of the reinforcement member 30c and the stitching | suture property requested | required of the sheet-like member 10c, etc. is confirmed, regardless of injection molding etc., the said By simply punching a plastic sheet having a thickness, it is possible to produce an integrally molded product of the sheet-like member 10c and the reinforcing member 30c.

  Other configurations in the present modification are the same as those in the third embodiment, and the sheet with a fan attachment portion of this modification exhibits substantially the same operations and effects as the sheet with a fan attachment portion in the third embodiment.

[Other Embodiments]
The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist.

  For example, in each of the above embodiments, the case where the outer shape of the cross section when the cylindrical portion of the fan is cut by a plane perpendicular to the central axis has been described, the cylindrical portion is perpendicular to the central axis. The outer shape of the cross section when cut by a plane may be a square, for example. In this case, the shape of the opening hole in the fan mounting portion is changed from a circular shape to a shape corresponding to the outer shape of the cylindrical portion, and the reinforcing member and the sewing jig have a shape corresponding to the outer shape of the cylindrical portion. What is necessary is just to use.

  In each of the above-described embodiments, the case where the fan having the flange portion is attached to the sheet with the fan attachment portion of the present invention has been described. In general, the protrusion protrudes in a direction substantially perpendicular to the tubular portion and the side surface of the tubular portion. If the fan comprises a fan body having a protruding portion provided on the cylindrical portion and a locking member that is inserted into the outside of the cylindrical portion and is mounted on the fan main body in a state of facing the protruding portion. Any fan can be attached to the seat with a fan attachment portion of the present invention. For example, the fan may be configured such that the back surface of the reinforcing member and the protruding portion are in direct contact with each other when the fan is attached.

  Moreover, in said 1st or 2nd embodiment, although the case where a sheet | seat with a fan attachment part was used when manufacturing an air-conditioning garment etc. by the method by a self-sheet system was demonstrated, this sheet | seat with a fan attachment part is used. Alternatively, it may be used when air-conditioning clothing or the like is manufactured by a method using another sheet method.

  Furthermore, in each of the above-described embodiments, the case where the reinforcing member and the sheet-like member are stitched in a circle around the center of the reinforcing member has been described.

Moreover, in FIG.11 (e)-(g), the state which attached the sheet | seat with a fan attachment part to cloth parts, such as an air-conditioning garment, is shown.

  As a feature common to these examples, it can be mentioned that the surfaces other than the surface fixed to the end of the sheet-like member among the surfaces of the reinforcing member are exposed without being covered with the sheet-like member. . However, in order to improve the appearance of the air-conditioning clothing and the like, the exposed surface of the front and back surfaces of the reinforcing member may be covered by some method. Even in this case, the inner side surface of the reinforcing member is exposed, and it does not change that the inner side surface of the reinforcing member comes into direct contact with the outer side surface of the cylindrical portion of the fan when the fan is attached. In the normal case where only one of the front and back surfaces of the reinforcing member is fixed to the end of the sheet-like member, when the fan is attached to the fan mounting portion, the reinforcing member and the locking member are in direct contact with each other, The inner surface of the reinforcing member is in direct contact with the outer surface of the cylindrical portion.

  The sheet with a fan attachment portion shown in FIG. 11A is that in the first embodiment. The entire surface of the reinforcing member 30 is covered with the sheet-like member 10, and the reinforcing member 30 cannot be seen from the front side of the sheet-like member 10. Further, the reinforcing member 30 and the sheet-like member 10 are stitched together with a thread 40.

  In the sheet with a fan attachment portion shown in FIG. 11B, the reinforcing member 30 and the sheet-like member 10 are made of a material that can be welded. The reinforcing member 30 is fixed to the sheet-like member 10 by welding the reinforcing member 30 and the sheet-like member 10.

  In the sheet with a fan attachment portion shown in FIG. 11C, the reinforcing member 30 is fixed to the end of the sheet-like member 10 on the surface of the sheet-like member 10 and around the opening hole. That is, the back surface of the reinforcing member 30 is fixed to the end portion of the sheet-like member 10 around the opening hole. Thereby, the reinforcing member 30 can be made conspicuous and used as a part of the design.

  The sheet with a fan attachment portion shown in FIG. 11 (d) is the one shown in FIG. Only a part of the surface of the reinforcing member 30 is covered with the sheet-like member 10, and a part of the reinforcing member 30 can be seen from the front side of the sheet-like member 10.

  The sheet with a fan attachment portion shown in FIG. 11E is that in the third embodiment. The fan-attached sheet 1b is stitched to the cloth part 200 with a thread 40.

  The sheet with a fan attachment portion shown in FIG. 11 (f) is a modification of the third embodiment. The material of the sheet-like member 10c and the material of the reinforcing member 30c are the same, and the sheet-like member 10c and the reinforcing member 30c are integrally molded. Further, the sheet 1c with a fan attachment portion is stitched to the cloth part 200 with a thread 40.

  Also in the sheet with a fan attachment portion shown in FIG. 11G, the material of the sheet-like member 10c and the material of the reinforcing member 30c are the same, and the sheet-like member 10c and the reinforcing member 30c are integrally molded. However, since the material has a certain level of strength, the thickness of the integrally molded product is made uniform as a whole. It can be considered that the sheet with a fan attachment portion shown in 11 (g) is a sheet when the thickness of the reinforcing member is brought close to zero in the sheet with a fan attachment portion shown in FIG.

  As described above, in the sheet with a fan attachment portion of the present invention, one of the front and back surfaces of the reinforcing means is fixed to the end portion of the sheet-like member around the opening hole. For this reason, when producing a fan mounting portion for mounting a fan on a sheet-like member, the sheet-like member is folded back as in the prior art, and a reinforcing means is inserted into the folded-up sheet-like member and the sheet of that portion is placed. Since it is not necessary to apply the backing cloth to the sheet-like member, the fan mounting portion can be easily produced on the sheet-like member. Further, since the end portion of the sheet-like member around the opening hole is not expanded or contracted by the non-stretchable reinforcing means, the end portion can be reinforced, so that even between the fan and the reinforcing means, or the fan Even if a strong force is applied between the fan and the sheet-like member, the fan is not easily detached from the fan mounting portion. Therefore, the present invention is suitable for use in air circulation mats and air-conditioning clothes.
