Technical Field

The present invention relates to a sheet with a fan attachment portion for attaching a fan used in an air-flow type pad, an air-conditioning suit, or the like for evaporating sweat from a human body by circulating air to a fan attachment portion of a sheet member such as a cloth.

Background

In recent years, air-flow pads, air-conditioning clothes, and the like 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, an air-conditioning suit is sewn from a material that is less likely to leak air, and two fan attachment portions for attaching fans are provided below the rear side portion of the air-conditioning suit. When the fan is attached to the fan attachment portion and the fan is operated, a large amount of outside air is taken into the air-conditioning suit from the fan. The taken-in outside air flows upward in parallel with the human body and is discharged from, for example, the collar and cuffs. The outside air evaporates sweat from the human body while flowing through the air conditioning suit, and the temperature of the body surface can be lowered by the heat of vaporization at the time of this evaporation (see, for example, patent document 3).

Next, a method of manufacturing the air-conditioning suit will be described. Here, a case where the air-conditioning suit is a working air-conditioning suit is considered. Before the description, a method for manufacturing a general coverall will be briefly described. When manufacturing a general work garment, first, a cloth is cut out in accordance with a pattern corresponding to the manufactured work garment to produce a cloth for each part. In the case of a typical coverall, the panels amount to tens of pieces. Next, a zipper, a snap fastener, or the like is attached to the cloth at a predetermined position. Then, the pieces of cloth are sewn to each other, whereby the general coveralls are completed.

The manufacturing method of the air conditioning suit is different from the manufacturing method of the common work suit in that: the method includes a step of providing a fan mounting portion for mounting a fan to a cloth piece at a portion corresponding to a lower portion of a rear side portion of the air conditioning suit. Here, the sheet member such as cloth or a cloth provided with the fan attachment portion is a sheet with the fan attachment portion. The manufacturing method of the air conditioning suit is roughly divided into two methods. One of the methods is a method of directly forming a fan mounting portion in a cloth piece itself at a portion corresponding to a lower portion of a rear side portion of an air-conditioning suit. Another method is a method of manufacturing a sheet with a fan attachment portion, which is provided with a fan attachment portion on a sheet-like member such as a small cloth, in advance, not on a cloth of the air-conditioning suit, and attaching the sheet to a portion corresponding to a lower portion of a rear side portion of the air-conditioning suit by sewing. Hereinafter, the former method is referred to as a self-sheet method, and the latter method is referred to as another sheet method, for convenience.

In the method based on the self-sheet method, the fan mounting portion needs to be made on the cloth at the sewing site, but the cloth cut out from the cloth used for the air-conditioning suit itself is used as the cloth, so that the sense of incongruity in appearance is small. On the other hand, in the method based on the other sheet system, for example, a square cloth having an appropriate size can be used as a raw material according to the size of the fan, and the sheet with the fan attachment portion can be mass-produced in a place different from the sewing site. Therefore, by using the sheet with the fan attachment portion which is mass-produced as described above, even a general sewing worker who does not have the equipment and skill required for processing the fan attachment portion can manufacture the air-conditioning suit. Here, from the economical viewpoint, it is not reasonable to use a cloth used for the air-conditioning suit itself as a cloth to be a material, and it is preferable to use a cloth of a different material. In this case, since the cloth used for the air-conditioning suit is a different material from the cloth used for the sheet with the fan attachment portion, a sense of incongruity in appearance may be generated.

In addition, in most conventional air-conditioning clothes, fans are mounted at two positions on the rear side portion. However, the fan may be an obstacle when the waist is too cool or the vehicle is riding, and the fan is often desired to be attached to a portion on the front side of the body portion. Fig. 12 is a schematic side view of a typical coverall. In general, in a general coverall, as shown in fig. 12, panels 200 are sewn to each other at positions on the front side. Here, the seam 210 formed by the sewing is indicated by a dotted line. In the air-conditioning suit, as in the case of a general work suit, since the fabric pieces 200 are sewn together at the front side, it is difficult to form the fan attachment portion at the sewn portion by a self-sheet method. In contrast, in the method using another sheet system, since the sheet with the fan attachment portion can be easily attached so as to straddle the adjacent cloth 200, the fan can be attached to the front side surface.

Even if an air flow-through pad, an air-conditioning suit, or the like is manufactured by using any of a self-sheet method and another sheet method, in order to improve an air-conditioning effect of a fan used for the air flow-through pad, the fan needs to be securely attached to a sheet member so that air does not leak from a fan attachment portion. On the other hand, in the case of washing an air-flow-through pad, an air-conditioning suit, or the like, it is necessary for the user to be able to easily remove the fan from the sheet member.

Therefore, as a fan used in air-conditioning clothes and the like, a fan having a structure shown in fig. 12 of patent document 2 is preferably used. The fan includes a fan body and an annular locking member for attaching the fan body to the sheet member. The fan body has a hollow cylindrical portion and a flange portion projecting from an upper end of the cylindrical portion in a direction substantially perpendicular to a side surface of the cylindrical portion. The fan is attached to the sheet-like member by inserting the annular locking member to the outside of the cylindrical portion, sandwiching the end of the sheet-like member around the opening hole of the sheet-like member with the back surface of the flange portion and the end surface of the annular locking member facing the flange portion, and engaging the locking piece provided in the cylindrical portion with the projection provided in the annular locking member.

Since a sheet member used in an air conditioning suit or the like is stretchable, in a configuration in which a fan attachment portion for attaching a fan is formed only in the sheet member as the fan attachment portion, the fan is easily removed from the sheet member when a strong force acts on the fan. In view of this, patent document 2 proposes to use, as a fan attachment portion, a fan attachment portion made of a non-stretchable material having an opening hole for attaching a fan and an end portion of a sheet member provided around the opening hole. Specifically, the fan mounting portion provided with the non-stretchable material is manufactured as follows. That is, first, a hole is formed at a predetermined position of the sheet member, and then the sheet member around the hole is folded back to the back side. Next, an annular non-stretchable material is inserted between the sheet members overlapped by the folding back. Then, a cloth is attached to a portion of the sheet member into which the non-stretchable material is inserted from the back side, and the sheet member and the cloth are sewn together with a thread at the portion. Thus, an open hole is formed, and a non-stretchable material is sewn around the open hole.

Patent document 1: japanese patent No. 4399765

Patent document 2: japanese re-publication of Japanese patent No. WO2006/009108

Patent document 3: japanese patent laid-open publication No. 2005-54299

However, in the above-described method of manufacturing the fan mounting portion, when the portion of the sheet-like member around the hole is folded back to the back side and the non-stretchable material is inserted between the sheet-like members overlapped by the folding back, it is difficult to arrange the opening hole in an accurate circular shape, which is troublesome. In addition, when the sheet-like member into which the non-stretchable material is inserted is attached with a cloth from the back side and the sheet-like member and the cloth are sewn together with a thread at the portion, care must be taken to maintain the shape of the opening hole, which is not only troublesome but also difficult for a beginner because it cannot be done by unskilled workers.

Disclosure of Invention

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

The present invention for achieving the above object is a sheet with a fan attachment portion for attaching a fan, the fan including: a fan main body having a cylindrical portion and a protruding portion provided in the cylindrical portion so as to protrude in a direction substantially perpendicular to a side surface of the cylindrical portion; and a locking member inserted to the outside of the cylindrical portion and attached to the fan main body in a state of facing the protruding portion, the sheet with the fan attachment portion comprising: a sheet member having an opening hole for passing the cylindrical portion of the fan; and a non-stretchable flat annular reinforcing unit having an opening portion having substantially the same shape as the outer edge of the cylindrical portion of the fan, one of the front and rear surfaces of the reinforcing unit being fixed to an end portion of the sheet-like member around the opening hole, the inner surface of the reinforcing unit being exposed, the cylindrical portion being inserted into the opening portion of the reinforcing unit and the locking member being attached to the fan body, and the fan being attached by sandwiching at least an end portion of the reinforcing unit between the protruding portion and the locking member, among the end portion of the sheet-like member around the opening hole and the end portion of the reinforcing unit.

According to the above configuration, in the present invention, one of the front surface and the back surface of the reinforcing unit is fixed to the end of the sheet-like member around the opening. Therefore, when the fan mounting portion for mounting the fan is manufactured on the sheet member, it is not necessary to perform the operation of folding back the sheet member, adding the reinforcement unit to the sheet member at the folded-back portion, and bringing the lining cloth into contact with the sheet member at the folded-back portion, as in the conventional case. Further, since the end portion of the sheet-like member around the opening hole can be reinforced by the non-stretchable reinforcing means so as not to stretch, the fan does not easily come off the fan mounting portion even if a strong force is applied between the fan and the reinforcing means or between the fan and the sheet-like member. Since the inner side surface of the reinforcing unit is exposed, when only one of the front surface and the back surface of the reinforcing unit is fixed to the end of the sheet-like member, the surface of each of the surfaces of the reinforcing unit other than the one surface fixed to the end of the sheet-like member is exposed without being covered with the sheet-like member, and the inner side surface of the fan mounting portion for mounting the fan is the inner side surface of the reinforcing unit. Therefore, by manufacturing the shape and size of the reinforcing unit with high accuracy, the shape and size of the fan mounting portion can be formed with high accuracy.

In the sheet with the fan attachment portion according to the present invention, the fan attachment portion can be easily formed on the sheet-like member. Further, even if a strong force is applied between the fan and the reinforcing unit or between the fan and the sheet member, the fan does not easily fall off from the sheet mounting portion.

Detailed Description

Hereinafter, embodiments for carrying out the invention according to the present application 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. Fig. 1(a) is a schematic front view of a sheet with a fan mounting portion as a first embodiment of the present invention, fig. 1(b) is a schematic back view of the sheet with the fan mounting portion, and fig. 1(c) is a schematic partial sectional view in a viewing direction of a-a of the sheet with the fan mounting portion. Fig. 2(a) is a schematic side view showing a state in which a fan used in an air-flow-through pad, an air-conditioning suit, or the like is inserted into an opening hole of a sheet with a fan attachment portion of the first embodiment, fig. 2(b) is a schematic side view showing a ring-shaped locking member in the fan, and fig. 2(c) is a schematic side view showing a state in which the fan is attached to the fan attachment portion. Fig. 3 is a schematic partial sectional view showing how the fan is mounted on the fan mounting portion.

The sheet with the fan attachment portion according to the first embodiment is configured such that the fan attachment portion for attaching a fan used for an air-flow type mat, an air-conditioning suit, or the like that evaporates sweat from a human body by circulating air is provided on a predetermined sheet member. As shown in fig. 1, the sheet 1 with the fan attachment portion includes a sheet member 10, an opening hole 20, and a non-stretchable flat annular reinforcing member (reinforcing means) 30. The sheet member 10 is an object to which a fan mounting portion is provided, and the fan mounting portion includes the opening hole 20, an end portion of the sheet member 10 around the opening hole 20, and the reinforcing member 30.

The sheet 1 with the fan mounting portion of the first embodiment is used in manufacturing air-conditioning clothes and the like by a method based on a self-sheet system. Therefore, as the sheet member 10, a member obtained by cutting cloth used for the air-conditioning suit itself is used. The material of the sheet member 10 is, for example, a normal woven fabric. Further, the sheet member 10 presents a front and a back. That is, the surface on the front side of the air-conditioning suit manufactured using the sheet 1 with the fan mounting portion is the surface of the sheet-like member 10, and the surface on the back side of the air-conditioning suit is the back surface of the sheet-like member 10. In addition, in accordance with the positional relationship of the front and back of the sheet member 10, in each portion, the surface on the side having the same positional relationship with the front surface of the sheet member 10 is also referred to as a front surface, and the surface on the side having the same positional relationship with the back surface of the sheet member 10 is also referred to as a back surface.

Now, the fan 100 used in the air flow-through pad, the air-conditioning suit, and the like will be briefly described. As shown in fig. 2, the fan 100 includes a motor, a fan body 110 housing the propeller, and an annular locking member 120 attached to the fan body 110. The fan main body 110 has a cylindrical portion 111; and a flange portion 112, the flange portion 112 protruding from the upper end of the cylindrical portion 111 in a direction substantially perpendicular to the side surface of the cylindrical portion 111. The cylindrical portion 111 has a circular outer shape in cross section when cut along a plane perpendicular to the central axis. Here, the outer diameter F of the cylindrical portion 111 is 64.5 mm. The locking member 120 is a dedicated member for attaching the fan body 110 to the fan attachment portion of the sheet 1 with the fan attachment portion. Two locking claws 113 are provided in the cylindrical portion 111 of the fan main body 110. On the other hand, a protrusion (not shown) is provided on the inner surface of the locking member 120, and the protrusion is engaged with each locking claw 113 to fix the locking member 120 to the outer surface of the cylindrical portion 111. Therefore, by inserting the locking member 120 to the outside of the cylindrical portion 111 and engaging with the fan main body 110, the locking member 120 can be easily attached to the fan main body 110 in a state facing the flange portion 112.

The opening 20 of the sheet 1 with the fan attachment portion is formed at a predetermined position of the sheet member 10 for passing the cylindrical portion 111 of the fan 100. In the first embodiment, as shown in fig. 1(a) and 1(b), 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 sheet-like member is formed with the open hole 20 having a diameter substantially equal to the outer diameter F of the cylindrical portion 111.

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

Further, the reinforcing member 30 is fixed to an end portion of the sheet member 10 around the opening hole 20 at the back surface of the sheet member 10. That is, the surface of the reinforcing member 30 is fixed to the end of the sheet member 10 around the opening hole 20. Specifically, the reinforcing member 30 is fixed to the sheet member 10 by sewing the reinforcing member 30 with the thread 40 to the end of the sheet member 10 around the opening hole 20. Here, in fig. 1(a) and 1(b), a seam 41 formed by the sewing operation is indicated by a broken line. The reinforcing member 30 and the sheet member 10 are sewn together in a circular shape in the vicinity of the substantial center of the reinforcing member 30. At this time, of the surfaces of the reinforcing member 30, the surfaces other than the surface fixed to the end of the sheet member 10 are exposed without being covered with the sheet member 10. Therefore, as shown in fig. 1(c), the inner surface 31 of the reinforcing member 30 is exposed.

Here, the relationship between the inner and outer diameters of the reinforcing member 30 and the diameter of the open hole 20 will be described. Generally, 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 the reinforcing member 30 needs to be attached to the end of the sheet member 10 around the opening hole 20. As described above, in the first embodiment, the open hole 20 having a diameter substantially equal to the inner diameter of the reinforcing member 30 is formed in the sheet member 10. Thus, when the reinforcing member 30 is fixed to the end portion of the sheet-like member 10 around the opening 20, the entire lower surface (front surface) of the reinforcing member 30 contacts the end portion of the sheet-like member 10 around the opening 20 as shown in fig. 1(c), and the reinforcing member 30 is not visible from the front side of the sheet-like member 10 as shown in fig. 1 (a).

However, the end of the sheet member 10 around the opening 20 needs to be cloth-reinforced. For example, in the case of sewing two woven fabrics, a force in a direction of tearing the two woven fabrics may be applied to the two woven fabrics during use, and therefore the two woven fabrics need a sufficient sewing strength corresponding to the purpose of use. In fact, under the condition that only two woven fabrics are overlapped and sewn, if a force is applied to the sewn portion in a direction of tearing the two woven fabrics, the thread located on the end edge side is torn from the sewn portion, and the two woven fabrics are simply torn. As a general method for preventing such a situation, for example, there is a method of: after the two woven fabrics are subjected to a treatment of folding back the end edge portions to form two layers, the two woven fabrics are sewn so as to overlap the two layers. In addition, when one of the objects to be sewn is a cloth and the other is a material that does not cause unraveling, it is also necessary to perform a reinforcement treatment on the cloth. Therefore, the cloth reinforcement treatment is a treatment for keeping sufficient strength of two members after sewing when at least one of the two members is made of cloth, and a treatment for preventing the opening of a thread with respect to the cloth member.

In the sheet 1 with the fan mounting portion of the first embodiment, as shown in fig. 1(c), a cloth reinforcing treatment utilizing an anchor effect is applied to a portion X of the sheet member 10 around the opening hole 20 at the back surface of the sheet member 10. Specifically, a predetermined resin is welded to a portion X of the sheet member 10 around the opening hole 20, thereby increasing the strength of the portion X of the sheet member 10 and preventing the thread from being opened. After the inner edge of the reinforcing member 30 is accurately aligned with the position of the opening hole 20, the reinforcing member 30 is sewn with a thread 40 in a circular shape to be integrated with the end of the sheet-like member 10 around the opening hole 20, as shown in fig. 1(a) and 1 (b).

When the fan 100 is attached to the sheet 1 with a fan attachment portion of the first embodiment, first, the cylindrical portion 111 of the fan main body 110 is inserted into the opening portion of the reinforcing member 30, and the lower surface of the flange portion 112 is brought into contact with the edge portion of the sheet member 10 around the opening hole 20 as shown in fig. 2 (a). 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 sandwiched between the lower surface of the flange portion 112 and the upper surface of the locking member 120, and in this sandwiched state, the locking claw 113 provided in the cylindrical portion 111 is engaged with the protrusion provided in the locking member 120, thereby attaching the locking member 120 to the fan main body 110. In this way, the fan 100 is mounted on the fan mounting portion as shown in fig. 2 (c). Here, when the fan 100 is mounted to the fan mounting portion, the reinforcing member 30 directly contacts the locking member 120, and the inner surface 31 of the reinforcing member 30 directly contacts the outer surface of the cylindrical portion 111.

Next, a method of manufacturing the sheet 1 with the fan mounting portion according to the first embodiment will be described.

The method for manufacturing the sheet 1 with the fan mounting portion according to the first embodiment includes the steps of: a first step of performing a cloth reinforcement process on a predetermined portion of the sheet member 10; a second step of forming an opening hole 20 in the sheet member 10; and a third step of sewing the reinforcing member 30 to the sheet member 10. Fig. 4 is a diagram for explaining a first step and a second step in the method for manufacturing the sheet 1 with the fan mounting portion according to the first embodiment, and fig. 5 is a diagram for explaining a third step in the method for manufacturing the sheet 1 with the fan mounting portion.

In the first step, a circular reinforcing sheet 60 shown in fig. 4(a) is prepared in advance. The reinforcing sheet 60 was a polypropylene sheet having a diameter of 75mm and a thickness of about 0.2 mm. In the first step, first, as shown in fig. 4(b), the sheet 60 for reinforcement treatment is disposed below the sheet member 10.

Next, as shown in fig. 4(b), the horn 70 for the ultrasonic welding machine having the annular pressing surface is pressed against the sheet member 10 so that its own central axis coincides with the central axis of the sheet material for reinforcement treatment 60. Here, the inner diameter of the horn 70 for the ultrasonic welding machine is smaller than the outer diameter F of the cylindrical portion 111. On the other hand, the outer diameter of the horn 70 is preferably larger than the diameter of the sheet for strengthening treatment 60. Then, when the horn 70 is ultrasonically vibrated, a portion of the reinforcing sheet 60 corresponding to the horn 70 is melted or softened and enters the back surface of the sheet member 10. In this way, the polypropylene resin is deposited on a predetermined portion of the back surface of the sheet member 10, and the strength of the portion can be improved. In fig. 4(c), when the sheet member 10 is viewed from the back side of the sheet member 10, a ring-shaped portion X which has been subjected to a reinforcing treatment and is a resin in which polypropylene is fused is indicated by oblique lines.

Next, in the second step, the reinforced portion X is cut using a cutter having a cutting blade having a diameter substantially equal to the outer diameter F of the cylindrical portion 111, as shown in fig. 4(d), thereby opening the opening 20 in the sheet member 10. Thereby, the width of the portion X is narrowed. Here, since the polypropylene resin is fused to the reinforced portion X, the line located on the cutting plane does not open.

Next, in the third step, the sewing operation of the reinforcing member 30 and the sheet member 10 is performed using a sewing machine. In the sewing operation in the third step, a predetermined sewing jig is used. As shown in fig. 5(a), the sewing jig 81 is formed in a substantially cylindrical shape. 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 portion of the sewing jig 81 is chamfered. In the third step, first, as shown in fig. 5(b), a sewing jig 81 is placed on a table 82 of the sewing machine. Next, the reinforcing member 30 is inserted into the sewing jig 81. Then, the sheet member 10 is inserted into the sewing jig 81 so that the surface on which the polypropylene resin is deposited in the first step faces downward. In this way, the reinforcing member 30 overlaps the sheet member 10. Next, as shown in fig. 5(b), the reinforcement member 30 and the sheet member 10 are sewn in a circular shape by using the sewing machine in a state where the column portion 83 of the presser foot of the sewing machine is brought into contact with the side wall of the sewing jig 81 at right angles. In this way, the sheet 1 with the fan mounting portion of the first embodiment is produced.

In the first step, the case where the fabric is reinforced by welding the resin to the sheet-like member 10 has been described, but the fabric may be reinforced by applying a commercially available overlock adhesive to the sheet-like member 10. For example, when a laminate processing is performed using a material used for rain gear as the sheet member 10 so that there is no opening of the thread and the member has sufficient strength for sewing, the first step of performing the cloth reinforcement treatment on a predetermined portion of the sheet member 10 can be omitted.

In the sheet with the fan attachment portion according to the first embodiment, when the sheet with the fan attachment portion is manufactured by fixing the reinforcing member to the end portion of the sheet member around the opening hole, it is not necessary to perform the operation of folding back the sheet member, adding the reinforcing member to the sheet member in the folded-back portion, and bringing the back cloth into contact with the sheet member in the folded-back portion as in the conventional art, and therefore, the fan attachment portion can be easily manufactured in the sheet member. Further, since the end portion of the sheet-like member around the opening hole can be reinforced by the non-stretchable reinforcing member so as not to stretch, the fan does not easily come off from the sheet mounting portion even if a strong force is applied between the fan and the reinforcing member or between the fan and the sheet-like member. Further, since the inner side surface of the fan attachment portion is the inner side surface of the reinforcing member, which is exposed without being covered with the sheet member except for the one surface fixed to the end portion of the sheet member, the shape and size of the fan attachment portion can be formed with high accuracy by making the shape and size of the reinforcing member with high accuracy.

In the sheet with the fan attachment portion according to the first embodiment, since the entire surface of the reinforcing member is completely covered with the sheet-like member, the reinforcing member cannot be seen from the outside when the fan is removed from the fan attachment portion, and therefore, the appearance of the air-conditioning suit or the like is not deteriorated. Further, the reinforcing treatment with the cloth utilizing the anchor effect is performed on the portion of the sheet-like member around the opening hole at the back surface of the sheet-like member, whereby the opening of the thread at the portion can be effectively prevented. Further, the reinforcing member can be firmly attached to the sheet-like member by sewing the reinforcing member to the portion of the sheet-like member subjected to the reinforcing treatment.

In the first embodiment, the case where the opening hole having a diameter substantially equal to 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 has been described, but the diameter of the opening hole may be larger than the inner diameter of the reinforcing member (the diameter of the opening). Fig. 6 is a schematic partial sectional view showing how a fan is attached to a fan attachment portion in a modification of the first embodiment. At this time, as shown in fig. 6, only a part of the upper surface (front surface) of the reinforcing member 30 is covered with the sheet member 10, and when the fan 100 is mounted on the fan mounting portion, only the end portion of the reinforcing member 30 around the opening 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 as a second embodiment of the present invention will be described. Fig. 7(a) is a schematic back view of a sheet with a fan mounting portion according to a second embodiment of the present invention, and fig. 7(B) is a schematic partial sectional view of the sheet with a fan mounting portion in the viewing direction B-B. In the second embodiment, the same reference numerals are given to the components having the same functions as those of the first embodiment, and detailed description thereof will be omitted.

As shown in fig. 7, the sheet 1a with a fan attachment portion according to the second embodiment includes a sheet member 10a, an opening 20, and a non-stretchable flat annular reinforcing member (reinforcing means) 30 a. The sheet 1a with the fan mounting portion is mainly used in manufacturing air-conditioning clothes and the like by a method based on a self-sheet system. The sheet 1a with a fan mounting portion of the second embodiment differs from the sheet 1 with a fan mounting portion of the first embodiment in that: for the sheet member 10a, as the reinforcement treatment of the cloth, a overlock sewing operation is adopted; a transparent member is used as the reinforcing member 30 a. The other structure is the same as that of the first embodiment.

Specifically, as shown in fig. 7(b), a plurality of slits 13 are formed in the end portion of the sheet member 10a around the opening 20, and the portion of the sheet member 10a where the slits 13 are formed is folded back to the back side. Here, the portion of the sheet member 10a to which the slits 13 are added is also referred to as "cut 14". Then, the cut portions 14 are bonded to the portion of the sheet member 10a overlapped therewith. In this way, in the second embodiment, the end portion of the sheet-like member 10a around the opening hole 20 is formed in two layers, and the strength thereof is improved and the opening of the thread is prevented. As shown in fig. 7 c, the reinforcing member 30a is fixed to an end portion (double-layered portion) of the sheet member 10a around the opening hole 20 on the back surface of the sheet member 10 a.

Next, a method of manufacturing the sheet 1a with the fan mounting portion according to the second embodiment will be described.

The method for manufacturing the sheet 1a with the fan mounting portion according to the second embodiment includes the steps of: a first step of forming the open hole 20 and the cut groove 13 in the sheet member 10 a; a second step of performing a cloth reinforcement process on a predetermined portion of the sheet member 10 a; and a third step of sewing the reinforcing member 30a to the sheet member 10 a. Fig. 8 is a diagram for explaining a first step and a second step in the method of manufacturing the sheet 1a with the fan mounting portion according to the second embodiment. Here, fig. 8(d) is a schematic sectional view in the viewing direction of C-C in fig. 8 (C).

In the first step, as shown in fig. 8(a), an opening 20 is opened at a predetermined position of the sheet member 10a by using a dedicated cutter, and a large number of slits 13 are formed in the end portion of the sheet member 10a around the opening 20. In the first step, a circular hole having a diameter of 55mm was formed as the opening hole 20. Further, a large number of slits 13 are radially formed in the end edge of the opening 20, that is, in the annular portion of the sheet member 10 surrounded by the circle C1 having a diameter of 55mm and the circle C2 having a diameter of 65 mm. The annular portion is formed by a large number of incisions 14 divided by the incision 13.

The length of the slit 13 formed in the sheet member 10, i.e., the value of 65mm described above, corresponds to the outer diameter 64.5mm of the cylindrical portion 111 of the fan 100. However, since the sheet member 10 used in the air conditioning suit or the like has elasticity, the above numerical values do not define a strict length of the slit 13. Similarly, in the present specification, the numerical values described with respect to the dimensions and the like of the sheet member 10 are not also defined to be strict values.

Next, the second step is performed. In the second step, a loop-shaped adhesive sheet 15 is prepared in advance. The adhesive sheet 15 was a polypropylene sheet having an inner diameter of 65mm, an outer diameter of 75mm and a thickness of 0.2 mm. In the second step, first, the sheet member 10a is placed on the soldering iron stand with its back surface facing upward. Then, as shown in fig. 8(b), the adhesive sheet 15 is disposed on the sheet member 10a so that its own center axis coincides with the center axis of the opening hole 20. Then, as shown in fig. 8(c), the cut portion 14 in the sheet member 10a is folded back over the adhesive sheet 15. At this time, if an iron is used and the cutting portions 14 are folded back by the tip edge of the iron and pressurized, the folded-back portions can be creased, and thus the cutting portions 14 can be reliably prevented from returning to the original state. The folding back of the cut portion 14 is not limited to the soldering iron, and may be performed mechanically by using a dedicated device.

Next, the horn 70 for the ultrasonic welding machine used in the first embodiment described above is pushed against the sheet-like member 10a at the portion corresponding to the folded-back cut portion 14. Then, when the horn 70 is ultrasonically vibrated, the adhesive sheet 15 is melted, and the portions of the cut portions 14 and the sheet-like member 10a superposed thereon are bonded to each other by the melted adhesive sheet (polypropylene resin), as shown in fig. 8 (d). In this way, the end portion of the sheet-like member 10a around the opening hole 20 is double-layered, and thus the strength of the end portion can be improved and the opening of the thread can be prevented. In addition, since each cut portion 14 is folded back in the second step, the diameter of the opening hole 20 is enlarged from 55mm to 65 mm.

As described above, the adhesive sheet 15 made of polypropylene is used as an adhesive for bonding the cut portion 14 and the portion of the sheet member 10a overlapped therewith. Therefore, the adhesive sheet is not limited to the adhesive sheet 15 made of polypropylene, and sheets of various materials can be used as long as they have the effect of an adhesive. In this case, the bonding method is not limited to the ultrasonic welding method, and a bonding method corresponding to the raw material used for the ultrasonic welding method, such as thermal welding by a heater, may be used.

Next, in the third step, the sewing operation of the reinforcing member 30a and the sheet member 10 is performed using a sewing machine. The sewing operation in this third step is the same as that in the third step of the first embodiment. Here, in fig. 7(a), a circular seam 41 formed by the sewing operation is shown by a broken line. In this way, the sheet 1a with the fan mounting portion shown in fig. 7 is produced.

The sheet with the fan mounting portion of the second embodiment has substantially the same operation and effect as the sheet with the fan mounting portion of the first embodiment. However, in order to manufacture the sheet with the fan attachment portion of the second embodiment, it is necessary to perform a work of folding back and bonding the end portions of the sheet-like member around the opening hole, and therefore, in this regard, the latter can be said to be easily manufactured as compared with the sheet with the fan attachment portion of the first embodiment.

In the second embodiment, a transparent member is used as the reinforcing member, but it is preferable to use an opaque member as the reinforcing member. This is because, when the reinforcing member is transparent, the cut portion is seen to be folded back when the fan attachment portion is viewed from the back side of the air-conditioning suit, and the appearance is poor.

[ third embodiment ]

Next, a sheet with a fan mounting portion as a third embodiment of the present invention will be described. Fig. 9(a) is a schematic rear view of a sheet with a fan attachment portion as a third embodiment of the present invention, and fig. 9(b) is a view for explaining a state in which the sheet with the fan attachment portion is attached to a predetermined cloth of an air-conditioning suit. Here, fig. 9(b) shows a state when viewed from the back side of the air-conditioning suit. In the third embodiment, the same reference numerals are given to the components having the same functions as those of the first embodiment, and detailed description thereof will be omitted.

As shown in fig. 9(a), the sheet 1b with a fan attachment portion according to the third embodiment includes a sheet member 10b, an opening 20, and a non-stretchable flat annular reinforcing member (reinforcing means) 30. The sheet 1b with a fan mounting portion of the third embodiment differs from the sheet 1 with a fan mounting portion of the first embodiment in that: the sheet 1b with the fan mounting portion is used for manufacturing air-conditioning clothes and the like by a method based on another sheet method. Specifically, in the first embodiment, since the sheet member 10 is a cloth used in the air-conditioning suit itself, for example, the sheet member 10 is much larger in size than the fan attachment portion, whereas in the third embodiment, as shown in fig. 9(a), the sheet member 10b is a member formed in a quadrangular shape slightly larger in size than the fan attachment portion. The other structure is the same as that of the first embodiment.

In this way, in the third embodiment, the sheet 1b with the fan mounting portion is used in manufacturing air-conditioning clothes and the like by a method based on another sheet method, and therefore, the sheet 1b with the fan mounting portion can be mass-produced in a place different from a sewing site. Therefore, by using the sheet 1b with the fan attachment portion which is mass-produced as described above, even a general sewing worker who does not have the equipment and skill required for processing the fan attachment portion can manufacture the air-conditioning suit and the like.

Specifically, when manufacturing the air-conditioning suit using the sheet 1b with the fan attachment portion of the third embodiment, first, a quadrangular hole having a size slightly smaller than the size of the sheet-like member 10b is opened at a predetermined position of the cloth of the air-conditioning suit corresponding to the attachment portion of the fan. Then, as shown in fig. 9(b), the end of the sheet-like member 10b is sewn to the portion of the cloth 200 around the hole, and the sheet 1b with the fan attachment portion is attached to the cloth 200. Here, in fig. 9(b), a quadrangular seam 42 formed by the sewing operation is shown by a broken line. The structure in which the sheet with a fan attachment portion 1b of the third embodiment is attached to the fabric panel 200 may be regarded as a sheet with a fan attachment portion, and the sheet with a fan attachment portion may be used for manufacturing air-conditioning clothes and the like by a method based on a self-sheet system.

The sheet with the fan mounting portion of the third embodiment has substantially the same operation and effect as the sheet with the fan mounting portion of the first embodiment.

However, in general, in the air-conditioning suit, the fabric pieces 200 are sewn together at the positions of the front side surfaces, as in the general work suit shown in fig. 12, and in the method based on the self-sheet method, it is difficult to form the fan attachment portions at the positions of the front side surfaces of the air-conditioning suit. In contrast, in the method using another sheet system, the sheet 1b with the fan attachment portion can be easily attached so as to straddle the adjacent cloth 200. Therefore, if the sheet with the fan attachment portion of the third embodiment is used, the fan can be provided at a position on the front side surface of the air-conditioning suit. This can prevent the fan from becoming an obstacle when, for example, riding in a car.

In the third embodiment, the description has been given of the case where the sheet member is formed in a quadrangular shape, but the shape of the sheet member is not limited to a quadrangular shape, and may be a triangular shape, a circular shape, or the like.

(modification of the third embodiment)

Next, a modified example of the third embodiment will be explained. Fig. 10(a) is a schematic rear view of a sheet with a fan mounting portion as a modification of the third embodiment, and fig. 10(b) is a schematic partial sectional view in a viewing direction of D-D of the sheet with the fan mounting portion.

As shown in fig. 10, a sheet 1c with a fan attachment portion as a modification of the third embodiment includes a sheet member 10c, an opening hole 20, and a non-stretchable flat annular reinforcing member (reinforcing means) 30c. In this modification, the sheet member 10c is made of the same material as the reinforcing member 30c, and the sheet member 10c and the reinforcing member 30c are integrally molded. Even in the sheet 1c with the fan attachment portion, it is conceivable that the surface of the reinforcing member 30c is fixed to the end of the sheet member 10c around the opening hole 20. Specifically, plastic can be used as a material for the sheet member 10c and a material for the reinforcing member 30c. In this case, the integrated molding of the sheet member 10c and the reinforcing member 30c can be easily manufactured by a method such as injection molding.

In addition, as long as the presence of the thickness of the plastic material that can satisfy both the strength required for the reinforcing member 30c and the sewing property required for the sheet member 10c is confirmed, the plastic material may be formed into an integrally molded product of the sheet member 10c and the reinforcing member 30c by simply punching a plastic sheet having the above thickness without injection molding or the like.

The other configurations in this modification are the same as those in the third embodiment, and the sheet with a fan attachment portion in this modification has substantially the same operation and effect as those of the sheet with a fan attachment portion in the third embodiment.

[ other embodiments ]

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention.

For example, in the above embodiments, the case where the outer shape of the cross section of the cylindrical portion of the fan cut by the plane perpendicular to the central axis thereof is circular was described, but the outer shape of the cross section of the cylindrical portion cut by the plane perpendicular to the central axis thereof may be, for example, a quadrangle. In this case, the shape of the opening hole of the fan mounting portion may be changed from a circular shape to a shape corresponding to the outer shape of the cylindrical portion, and a shape corresponding to the outer shape of the cylindrical portion may be used as the reinforcing member or the sewing jig.

In the above 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, but in general, any fan can be attached to the sheet with the fan attachment portion of the present invention as long as the fan includes a fan main body having a cylindrical portion and a protruding portion provided on the cylindrical portion so as to protrude in a direction substantially perpendicular to a side surface of the cylindrical portion, and a locking member inserted to the outside of the cylindrical portion and attached to the fan main body in a state of facing the protruding portion. For example, the fan may be configured such that the rear surface of the reinforcing member directly contacts the protruding portion when the fan is mounted.

In the first or second embodiment, the description has been given of the case where the sheet with the fan attachment portion is used when the air-conditioning clothing or the like is manufactured by the method based on the self-sheet method, but the sheet with the fan attachment portion may be used when the air-conditioning clothing or the like is manufactured by a method based on another sheet method.

In addition, in the above embodiments, the case where the reinforcing member and the sheet-like member are sewn together in a circular shape in the vicinity of the substantially center of the reinforcing member has been described, but for example, the reinforcing member and the sheet-like member may be sewn together in a double layer at a portion near the inner edge and a portion near the outer edge of the reinforcing member. Alternatively, the suture may be sewn in a zigzag manner.

In the above embodiments, it is preferable to use a flexible member as the sheet-like member in view of comfort and the like. However, in the modification of the third embodiment, when a small-sized fan is used as the fan, it is not necessary to use a member having flexibility as the sheet-like member.

In the first or second embodiment, the case where a normal woven fabric is used as a material of the sheet-like member is described. In the air-conditioning clothing, the sheet-like member is not necessarily required to have moisture permeability in terms of its properties. Therefore, depending on the purpose of use of the air conditioning clothing, an inexpensive material such as a plastic sheet such as a vinyl sheet can be used as the material for the sheet member.

In addition, in the above embodiments, the case where the reinforcing member is fixed to the sheet-like member by sewing the reinforcing member to the end portion of the sheet-like member around the opening has been described, but in the case where the reinforcing member and the sheet-like member are made of weldable raw materials, the reinforcing member may be fixed to the sheet-like member by welding the reinforcing member to the end portion of the sheet-like member around the opening.

The above description specifically describes the mode of the sheet with the fan attachment unit for carrying out the present invention. Finally, fig. 11 shows, as a summary thereof, a representative structure of the sheet with a fan mounting portion of the present invention. Here, fig. 11(a) to 11(d) are structural examples of a sheet with a fan attachment portion used in manufacturing air-conditioning clothes and the like by a method based on a self-sheet method, and fig. 11(e) to 11(g) are structural examples of a sheet with a fan attachment portion used in manufacturing air-conditioning clothes and the like by a method based on another sheet method. Fig. 11(e) to 11(g) show a state in which the sheet with the fan attachment portion is attached to a cloth such as an air-conditioning suit.

As a feature common to the above examples, a point can be given in which, of the surfaces of the reinforcing member, the surface other than the surface fixed to the end of the sheet-like member is exposed without being covered with the sheet-like member. Among these, in order to improve the aesthetic appearance of air-conditioning clothes and the like, the exposed surface of the front surface and the rear surface of the reinforcing member may be shielded by some method. Even in this case, the inner surface of the reinforcing member is exposed, and the inner surface of the reinforcing member directly contacts the outer surface of the cylindrical portion of the fan when the fan is mounted. In a normal case where only one of the front surface and the back surface of the reinforcing member is fixed to the end of the sheet-like member, when the fan is mounted to the fan mounting portion, the reinforcing member directly contacts the locking member, and the inner surface of the reinforcing member directly contacts the outer surface of the cylindrical portion.

The sheet with the fan mounting portion shown in fig. 11(a) has the structure of the first embodiment. The entire surface of the reinforcing member 30 is covered with the sheet member 10, and the reinforcing member 30 cannot be seen from the front side of the sheet member 10. Further, the reinforcing member 30 and the sheet member 10 are sewn with a thread 40.

In the sheet with a fan attachment portion shown in fig. 11(b), the reinforcing member 30 and the sheet member 10 are made of a weldable raw material. The reinforcing member 30 is fixed to the sheet member 10 by welding the reinforcing member 30 to the sheet member 10.

In the sheet with the fan attachment portion shown in fig. 11(c), the reinforcing member 30 is fixed to the end portion of the sheet member 10 around the opening hole at the surface of the sheet member 10. That is, the back surface of the reinforcing member 30 is fixed to the end of the sheet member 10 around the opening. This makes the reinforcing member 30 conspicuous and can be used as a part of the design.

The sheet with the fan mounting portion shown in fig. 11(d) has the structure shown in fig. 6. Only a part of the surface of the reinforcing member 30 is covered with the sheet member 10, and the part of the reinforcing member 30 can be seen from the front side of the sheet member 10.

The sheet with the fan mounting portion shown in fig. 11(e) is the structure in the third embodiment. The sheet 1b with the fan attachment portion is sewn to the cloth 200 by a thread 40.

The sheet with the fan mounting portion shown in fig. 11(f) has a structure in a modification of the third embodiment. The sheet member 10c is made of the same material as the reinforcing member 30c, and the sheet member 10c and the reinforcing member 30c are integrally molded. Further, the sheet 1c with the fan attachment portion is sewn to the cloth 200 by the thread 40.

Even in the sheet with the fan attachment portion shown in fig. 11(g), the sheet member 10c is formed integrally with the reinforcing member 30c in the same manner as the sheet member 10c is formed from the reinforcing member 30c. Wherein the raw material has a certain degree of strength, thereby making the thickness of the integrally formed piece uniform as a whole. The sheet with a fan mounting portion shown in fig. 11(g) can be considered as a structure in which the thickness of the reinforcing member is made to be approximately zero in the sheet with a fan mounting portion shown in fig. 11 (f).

Note that each configuration example shown in fig. 11 is a representative example, and it is needless to say that the configuration of the sheet with a fan attachment portion of the present invention is not limited to this.

Industrial applicability of the invention

As described above, in the sheet with the fan attachment portion according to the present invention, one of the front surface and the back surface of the reinforcing unit is fixed to the end portion of the sheet-like member around the opening hole. Therefore, when the fan mounting portion for mounting the fan is manufactured on the sheet member, it is not necessary to perform the operation of folding back the sheet member, adding the reinforcement unit to the sheet member at the folded-back portion, and bringing the lining cloth into contact with the sheet member at the folded-back portion, as in the conventional case. Further, since the end portion of the sheet-like member around the opening hole can be reinforced by the non-stretchable reinforcing means so as not to stretch, the fan does not easily come off the fan mounting portion even if a strong force is applied between the fan and the reinforcing means or between the fan and the sheet-like member. Thus, the present invention is suitable for use in air flow-through pads, air conditioning garments, and the like.
