Description

[Technical field]

[0001] The present invention relates to an air exhaust port adjustment mechanism for adjusting the opening degree of an air exhaust port formed between the back collar of the air-conditioned clothing and the back neck of the human body, which exhausts air circulating within the air-conditioned clothing to the outside. [Background technology]

[0002] In recent years, air-conditioned clothing has been put to practical use, which evaporates sweat from the human body by circulating air in an air flow passage formed between the body and the air-conditioned clothing using a blowing means. A detailed explanation of the principle and structure of the air-conditioned clothing is described in detail, for example, in Patent Document 1. Fig. 7 is a diagram for explaining the air flow in the air-conditioned clothing, and Fig. 8 is a diagram for explaining an air exhaust section formed between the rear of the collar and the rear of the neck of the human body in a conventional air-conditioned clothing. An elastic belt is attached to the hem of this air-conditioned clothing 1, and a zipper for opening and closing is provided on the front side of the air-conditioned clothing 1. In addition, two blowing means 11, 11 are attached to the lower part of the air-conditioned clothing 1. Here, a fan having a propeller is used as the blowing means 11.

[0003] After fastening the belt and closing the zipper, the two air blowing means 11, 11 are operated, and as shown in FIG. 7, outside air is taken into the air-conditioned suit 1 from each air blowing means 11. The taken-in outside air then flows upward in parallel with the human body through the air flow passage and is discharged from the air exhaust section. Here, the air exhaust sections include an opening between the front collar of the air-conditioned suit 1 and the front neck of the human body, an opening between the back collar 12 of the air-conditioned suit 1 and the back neck of the human body, and an opening between the sleeve of the air-conditioned suit 1 and the arm of the human body. Among these openings, the opening between the back collar 12 and the back neck is clearly formed unlike the other openings, and is more important than the other openings in that it discharges the most air. Hereinafter, the opening formed between the back collar 12 and the back neck will be referred to as the "air exhaust port" to distinguish it from the other air exhaust sections.

[0004] The sweat from the human body evaporates while the outside air taken into the air-conditioned suit 1 flows through the air flow passage, and the heat of vaporization at the time of evaporation can lower the temperature of the body surface. Therefore, in order for the air-conditioned suit 1 to efficiently perform its cooling function, it is necessary to reduce the resistance that the air flowing through the air flow passage receives from the air exhaust section and to allow a large amount of air to flow parallel to the human body. In addition, the wearer of the air-conditioned suit 1 may want to adjust the cooling effect of the air-conditioned suit 1 depending on the purpose of use. For this reason, the conventional air-conditioned suit 1 is equipped with a mechanism for adjusting the opening degree of each air exhaust section. Here, due to the nature of the air exhaust section, the opening degree of each air exhaust section cannot be clearly expressed in numerical values, but the larger the opening degree, the smaller the resistance that the air receives from that air exhaust section, and the larger the amount of air discharged from that air exhaust section. Specifically, the sleeves of the air-conditioned suit 1 are provided with, for example, two buttons, like ordinary clothing such as a dress shirt. By attaching or removing such buttons, the opening degree of the air exhaust section between the sleeves and the arms can be adjusted. Also, by adjusting the position of the fastener, the degree of opening of the air exhaust port between the front collar and the front neck can be easily adjusted. In this case, the further up the fastener is pulled, the smaller the degree of opening of the air exhaust port between the front collar and the front neck becomes. Furthermore, as shown in FIG. 8, the conventional air-conditioned suit 1 is provided with a set of adjustment cords 21 for widening or narrowing the space between the back collar 12 and the back neck. The ends of each adjustment cord 21 are attached to the inner surface of the back collar 12. By tying the set of adjustment cords 21 and adjusting their length, the air exhaust port 13 can be formed between the back collar 12 and the back neck, and the degree of opening of the air exhaust port 13 can be adjusted. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2005-54299 A Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, in conventional air-conditioned clothing 1, the mechanism for adjusting the opening degree of air exhaust port 13 between the back collar 12 and the back neck uses a set of adjustment cords 21 that are tied to the desired length to provide slack near the back collar 12, as shown in Fig. 8. However, in practice, it is very difficult to tie the set of adjustment cords 21 to the desired length, and most wearers are unable to properly adjust the opening degree of air exhaust port 13 between the back collar 12 and the back neck, making it difficult for the air-conditioned clothing 1 to perform to its full potential.

[0007] If the opening of the air exhaust port 13 between the back collar 12 and the back of the neck is small compared to the amount of outside air taken into the air flow passage from the ventilation means 11, the following problems will occur: (1) It will be impossible to ensure a sufficient amount of air flowing, especially along the back. (2) The air pressure near the back will increase, causing the fabric of the air-conditioned suit 1 to swell, and a greater proportion of the air in the air flow passage near the back will flow through parts away from the body that do not contribute to cooling the body. (3) The fabric of the air-conditioned suit 1 will swell, making it difficult for the wearer to work, for example, in a narrow space. (4) The fabric of the air-conditioned suit 1 will swell, damaging the appearance of the air-conditioned suit 1.

[0008] On the other hand, if the opening of the air exhaust port 13 between the back collar 12 and the back neck is too large compared to the amount of outside air taken into the air flow passage from the ventilation means 11, the air exhaust port 13 will be too large, damaging the appearance of the air-conditioned suit 1. Moreover, because the amount of air exhausted from the air exhaust port 13 becomes too large, the amount of air exhausted from other air exhaust parts will decrease significantly, and the balance of the cooling effect on each part of the human body will be significantly lost. Also, even if a pair of adjustment cords 21 is tied to an appropriate length, the pair of adjustment cords 21 is formed to a certain length for that purpose, and the tips of the adjustment cords 21 gather near the knot, which becomes an obstacle to air exhaust.

[0009] Therefore, there is a need for a new air outlet adjustment mechanism that can easily adjust the opening degree of the air outlet 13 between the back collar 12 and the back neck. Such a new air outlet adjustment mechanism must satisfy the following requirements: (1) it must not interfere with washing, (2) it must be possible to reliably form the air outlet 13, (3) it must be inexpensive to manufacture, and (4) it must not get in the way of the user when it is not necessary to form the air outlet 13. Here, even if the new air outlet adjustment mechanism does not form the air outlet 13 between the back collar 12 and the back neck, when the blowing means 11 is operated, a certain degree of opening is automatically secured between the back collar 12 and the back neck by the air pressure, so that it may be better not to form the air outlet 13 depending on the purpose of use.

[0010] The present invention has been made based on the above-mentioned circumstances, and aims to provide an air exhaust port adjustment mechanism that can easily adjust the opening degree of the air exhaust port formed between the back collar of the air-conditioned clothing and the back of the neck of the human body. [Means for solving the problem]

[0011] The air exhaust port adjustment mechanism of the first invention for achieving the above-mentioned object is an air exhaust port adjustment mechanism for adjusting the opening degree of an air exhaust port formed between the back collar of an air-conditioned clothing and the back neck of a human body, which uses a blowing means to circulate air within an air flow passage formed between the air-conditioned clothing and the human body, and which exhausts air circulating within the air flow passage to the outside, the air exhaust port adjustment mechanism comprising: an adjustment belt having a first attachment part and attached to a first position on the inner surface of the fabric of the air-conditioned clothing at the back collar or its periphery, and a second attachment part formed on the back collar or a predetermined position therearound different from the first position where the adjustment belt is attached, and which can be attached to the first attachment part; and by attaching the first attachment part to the second attachment part, the pressure of the air circulating within the air flow passage is utilized to form the air exhaust port between the back collar and the back neck of the human body with a predetermined opening degree.

[0012] In the air exhaust port adjustment mechanism of the first invention, with the above-mentioned configuration, by simply attaching the first mounting part to the second mounting part, slack can be secured near the back collar of the air-conditioned clothing, making it easy to form an air exhaust port.

[0013] In addition, a second invention for achieving the above-mentioned object is an air exhaust port adjustment mechanism for adjusting the opening degree of an air exhaust port formed between the back collar of an air-conditioned clothing, which uses a blowing means to circulate air within an air flow passage formed between the back collar and the back neck of the human body, and which exhausts air circulating within the air flow passage to the outside, the air exhaust port adjustment mechanism comprising a first adjustment belt attached to a first position on the inner surface of the fabric of the air-conditioned clothing at the back collar or its periphery, and a second adjustment belt attached to the back collar or its periphery at a second position different from the first position where the first adjustment belt is attached, and by attaching the first adjustment belt to the second adjustment belt, the pressure of the air circulating within the air flow passage is utilized to form the air exhaust port between the back collar and the back neck of the human body with a predetermined opening degree.

[0014] In the air exhaust port adjustment mechanism according to the second invention, the above-mentioned configuration allows for easy formation of an air exhaust port by simply attaching the first attachment part to the second attachment part, ensuring slackness near the rear collar of the air-conditioned clothing. Furthermore, by providing a second adjustment belt having a second attachment part, when the first attachment part is attached to the second attachment part, the first attachment part remains inside the air-conditioned clothing and is not visible from the outside, so that the appearance is not marred. Effect of the Invention

[0015] The air exhaust port adjustment mechanism of the present invention makes it possible to easily form an air exhaust port near the back collar of the air-conditioned clothing, and also makes it possible to easily adjust the opening degree of the air exhaust port in multiple stages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] [First embodiment] First, a first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic front view of an air-conditioned garment equipped with an air exhaust port adjustment mechanism according to a first embodiment of the present invention. Fig. 2(a) is a schematic plan view of an adjustment belt in the air exhaust port adjustment mechanism of the first embodiment, Fig. 2(b) is a schematic development of a collar of the air-conditioned garment in which a through-hole is formed in the air exhaust port adjustment mechanism, and Fig. 2(c) is a schematic development of a collar of the air-conditioned garment to which an adjustment belt in the air exhaust port adjustment mechanism is attached. Fig. 3(a) is a schematic view showing a collar of the air-conditioned garment in which an air exhaust port is formed by the air exhaust port adjustment mechanism of the first embodiment, as viewed from above, Fig. 3(b) is a schematic cross-sectional view of the collar of the air-conditioned garment in the direction of the arrow AA, and Fig. 3(c) is a schematic enlarged view of the vicinity of a fastener in the collar of the air-conditioned garment.

[0019] The air exhaust port adjustment mechanism 50 of the first embodiment is provided in the rear collar 12 of the air-conditioned clothing 1 as shown in FIG. 1, and is for adjusting the opening degree of the air exhaust port formed between the rear collar 12 of the air-conditioned clothing 1 and the rear neck of the human body. Here, the air-conditioned clothing 1 cools the human body by circulating air in an air flow passage formed between the air-conditioned clothing 1 and the human body using a blowing means, and the air exhaust port exhausts the air flowing in the air flow passage to the outside. In addition, the rear neck portion includes the upper part of the back, depending on the body shape of the wearer. In the first embodiment, for ease of explanation, as shown in FIG. 1, the air-conditioned clothing 1 equipped with the air exhaust port adjustment mechanism 50 is described as having a stand-up collar portion 2 that does not fold back as the collar portion. In addition, a zipper 3 for opening and closing is provided on the front side of this air-conditioned clothing 1.

[0020] As shown in Figures 2 and 3, the air exhaust port adjustment mechanism 50 of the first embodiment comprises an adjustment belt 51 and two through holes 52a, 52b formed at predetermined positions in the back collar of the air-conditioned clothing 1. Figures 2(b) and (c) show the stand-up collar 2 of the air-conditioned clothing 1 when it is unfolded and spread out flat, with the inner surface of the stand-up collar 2 facing the wearer's neck facing up. Therefore, in Figures 2(b) and (c), the center of the stand-up collar 2 corresponds to the back collar 12 of the air-conditioned clothing 1.

[0021] 2(a), the adjustment belt 51 has a belt-shaped member 511 and one fastener 512. The fastener 512 is provided at one end of the belt-shaped member 511. In the first embodiment, a button is used as the fastener 512, and this button 512 is sewn to one end of the belt-shaped member 511. In fact, a commercially available button can be used as the fastener 512 as it is.

[0022] 2(c) and 3, the other end of the belt-shaped member 511 is an attachment part 513 for attaching to a predetermined position on the back collar 12 on the inner surface of the fabric of the air-conditioned clothing 1. Specifically, as shown in Fig. 2(c), the attachment part 513 of the belt-shaped member 511 is sewn to the lower part of the stand-up collar 2 of the air-conditioned clothing 1, slightly to the right of the center. At this time, the adjustment belt 51 is positioned so that the fastener 512 faces the inner surface of the stand-up collar 2 (back collar 12).

[0023] The through-holes 52a and 52b are for engaging with the fastener 512 to attach the button which is the fastener 512. These through-holes 52a and 52b correspond to the engaging portions of the present invention. In the first embodiment, as the through-holes 52a and 52b, ordinary button holes formed by making cut lines are used. Therefore, the button which is the fastener 512 and the button holes which are the through-holes 52a and 52b are each, for example, of the same shape as the button and the button hole in a shirt or the like, and the relationship between the button which is the fastener 512 and the button holes which are the through-holes 52a and 52b is the same as the relationship between the button and the button hole in a shirt or the like. The two through-holes 52a and 52b are formed at predetermined positions on the standing collar portion 2 (rear collar portion 12) which is different from the position where the adjustment belt 51 is attached. Specifically, as shown in FIGS. 2(b) and (c), the two through-holes 52a and 52b are formed side by side at a portion slightly to the left of the center of the standing collar portion 2 of the air-conditioning clothing 1 and at the lower part thereof. Here, the through-hole 52b is formed on the left side of the through-hole 52a. Hereinafter, the through-hole 52a will also be referred to as the first through-hole, and the through-hole 52b will also be referred to as the second through-hole. Also, each of the through-holes 52a and 52b is formed such that the cutting direction of the button hole is substantially parallel to the height direction (vertical direction) of the standing collar portion 2.

[0024] Now, as shown in FIG. 2(c), let the length of the adjustment belt 51 from the attachment portion 513 of the belt-like member 511 to the fastener 512 be L2, the distance along the standing collar portion 2 (fabric of the air-conditioning clothing 1) from the position where the adjustment belt 51 is attached (attachment portion 513 of the belt-like member 511) to the first through-hole 52a be L1a, and the distance along the standing collar portion 2 (fabric of the air-conditioning clothing 1) from the position where the adjustment belt 51 is attached (attachment portion 513 of the belt-like member 511) to the second through-hole 52b be L1b. At this time, L1a < L1b, and also, L1a > L2. That is, the length L2 of the adjustment belt 51 from the attachment portion 513 of the belt-like member 511 to the fastener 512 is shorter than the distances L1a and L1b along the standing collar portion 2 (fabric of the air-conditioning clothing 1) from the position where the adjustment belt 51 is attached to the respective through-holes 52a and 52b.

[0025] With the air exhaust port adjustment mechanism 50 of the first embodiment configured in this manner, when fastener 512 is passed through either of through holes 52a, 52b and fastened, as shown in Fig. 3, the inner surface of fastener 512 abuts against the outer surface of back collar 12 at the portion where the through hole is formed, and fastener 512 is firmly fixed to back collar 12. At this time, length L2 of adjustment belt 51 from attachment portion 513 of belt-shaped member 511 to fastener 512 is shorter than distances L1a, L1b along stand-up collar 2 from the attachment position of adjustment belt 51 to each of through holes 52a, 52b, so that when the air-conditioned clothing 1 is worn, the air-conditioned clothing 1 slackens in the vicinity of back collar 12, and air exhaust port 13 can be formed between back collar 12 and the wearer's back neck. Furthermore, since distance L1b along the stand-up collar portion 2 from the position where adjustment belt 51 is attached to the second through hole 52b is greater than distance L1a along the stand-up collar portion 2 from the position where adjustment belt 51 is attached to the first through hole 52a, the opening degree of air exhaust port 13 when fastener 512 is attached to the second through hole 52b is greater than the opening degree of air exhaust port 13 when fastener 512 is attached to the first through hole 52a.

[0026] Specifically, when the wearer of the air-conditioned clothing 1 wishes to exhaust a small amount of air from the air exhaust port 13, he or she need only attach the fastener 512 to neither of the through holes 52a, 52b. Even if the air exhaust port 13 is not formed using the air exhaust port adjustment mechanism 50 in this way, when the blower means 11 of the air-conditioned clothing 1 is operated, a certain amount of opening is automatically secured between the back collar 12 and the back neck due to the pressure of the air flowing through the air flow passage, and this opening becomes the air exhaust port 13 from which a small amount of air can be exhausted to the outside. When the wearer wishes to exhaust a normal amount of air from the air exhaust port 13, he or she need only attach the fastener 512 to the first through hole 52a, and when the wearer wishes to exhaust a large amount of air from the air exhaust port 13, he or she need only attach the fastener 512 to the second through hole 52b. In this way, by using the air exhaust port adjustment mechanism 50 of the first embodiment, the wearer can select the opening degree of the air exhaust port 13 from three levels of opening degree depending on the purpose of using the air-conditioned clothing 1, and obtain the desired cooling effect.

[0027] Next, a method for producing the air outlet adjustment mechanism 50 of the first embodiment will be described. First, on the inner surface of the collar 2 of the air-conditioned clothing 1, a scribing line for attaching the adjustment belt 51 is drawn at the position where the adjustment belt 51 is to be attached, and scribing lines for making the through holes 52a, 52b are drawn at the positions where the through holes 52a, 52b are to be formed. After that, the through holes are formed at the locations indicated by the scribing lines for making the through holes in the same manner as for making normal buttonholes. In this way, two through holes 52a, 52b are formed in the collar 2 of the air-conditioned clothing 1, as shown in Fig. 2(b). Here, in Fig. 2(b), the scribing line 4 for attaching the adjustment belt is shown by a dashed line.

[0028] Next, a belt-shaped member 511 of a predetermined length is prepared, and a button is attached as fastener 512 to one end of the belt-shaped member 511. This results in an adjustable belt 51 as shown in Fig. 2(a). At this time, the length of the adjustable belt 51 is adjusted so that the length L2 of the adjustable belt 51 from the attachment part 513 of the belt-shaped member 511 to the fastener 512 is shorter than the distances L1a, L1b along the stand-up collar part 2 from the score line 4 for attaching the adjustment belt to each of the through-holes 52a, 52b.

[0029] Thereafter, adjustment belt 51 is positioned so that fastener 512 faces the inner surface of stand-up collar 2 (the fabric of air-conditioned clothing 1) and the longitudinal direction of belt-shaped member 511 is approximately parallel to the longitudinal direction of stand-up collar 2, and attachment portion 513 of belt-shaped member 511 is sewn to the location indicated by score line 4 for attachment of the adjustment belt drawn on stand-up collar 2. In this way, as shown in Figure 2(c), adjustment belt 51 is attached to the inner surface of stand-up collar 2 and air exhaust port adjustment mechanism 50 is completed. In this way, the air exhaust port adjustment mechanism 50 of the first embodiment can be easily manufactured.

[0030] The air exhaust port adjustment mechanism of the first embodiment has a fastener provided at one end of a belt-shaped member, the other end of which is an adjustment belt attached to a predetermined position on the back of the collar on the inner surface of the fabric of the air-conditioned clothing, and two through holes formed at predetermined positions on the back of the collar different from the position where the adjustment belt is attached, for engaging with and attaching the fastener, and the length of the adjustment belt from the other end of the belt-shaped member to the fastener is shorter than the distance along the fabric of the air-conditioned clothing from the position where the adjustment belt is attached to each through hole. As a result, by simply attaching the fastener to the through hole, slack can be secured near the back of the collar of the air-conditioned clothing, and an air exhaust port can be easily and reliably formed. In addition, the opening degree of the air exhaust port can be easily adjusted to three levels depending on which through hole the fastener is attached to or not attached to. Note that since the air exhaust port adjustment mechanism of the first embodiment is configured with an adjustment belt and two through holes, when it is not necessary to form an air exhaust port, this air exhaust port adjustment mechanism does not get in the way of the wearer.

[0031] In addition, since the air exhaust port adjustment mechanism of the first embodiment uses a commercially available button as the fastener, even if the button comes off and is lost, the user can easily obtain a replacement button and easily repair the button. Moreover, since the through hole is a buttonhole made by making a cut line, the through hole can be easily formed in the same manner as the method for forming a normal buttonhole. Therefore, the air exhaust port adjustment mechanism of the first embodiment can be manufactured easily and inexpensively.

[0032] Furthermore, in the air exhaust port adjustment mechanism of the first embodiment, the fastener is attached to the adjustment belt so that it faces the inner surface of the air-conditioned clothing fabric, so when the fastener is attached to the through hole, the fastener does not come into direct contact with the skin of the human body, and the wearer does not experience any discomfort due to the contact of the fastener.

[0033] In addition, the air-conditioned clothing equipped with the air exhaust port adjustment mechanism of the first embodiment has the following advantages over air-conditioned clothing equipped with a set of adjustable cords, which is a conventional air exhaust port adjustment mechanism. Conventionally, when using air-conditioned clothing equipped with a set of adjustable cords, most wearers did not tie the set of adjustable cords and did not form an air exhaust port between the rear of the collar and the rear of the neck. Furthermore, the length of the set of adjustable cords was not adjusted according to the purpose of use. For this reason, air-conditioned clothing equipped with a set of adjustable cords was not used in a state in which it could fully demonstrate its performance. In contrast, by shipping air-conditioned clothing equipped with the air exhaust port adjustment mechanism of the first embodiment with fasteners attached to the through holes in advance, the performance of the air-conditioned clothing can be fully demonstrated even if the wearer uses the air-conditioned clothing in the state at the time of shipping. Therefore, if air-conditioned clothing equipped with the air exhaust port mechanism of the first embodiment becomes widespread, it is possible to significantly improve the wearer's evaluation of the performance of the air-conditioned clothing. In addition, when washing air-conditioned clothing equipped with the air exhaust port adjustment mechanism of the first embodiment, the buttons (fasteners) are removed from the button holes (through holes). As a result, no undue force is applied to the buttons during washing, so the air-conditioned suit can be washed without any problems. Furthermore, in air-conditioned suits with a single set of adjustment cords, the ends of the adjustment cords that gather near the knots of the adjustment cords form an obstacle to air exhaust, but in air-conditioned suits with the air exhaust port adjustment mechanism of the first embodiment, there is no excess part in the adjustment belt, and the resistance that the adjustment belt exerts on the air is very small, so the air exhaust port adjustment mechanism itself does not impede air exhaust.

[0034] In the first embodiment, the air exhaust port adjustment mechanism of the present invention is applied to an air-conditioned suit having a stand-up collar, but the air exhaust port adjustment mechanism of the present invention may also be applied to an air-conditioned suit having a folded-up collar. In this case, the fastener is covered by the folded-up collar, so no strange appearance is created.

[0035] [Second embodiment] Next, an air exhaust port adjustment mechanism according to a second embodiment of the present invention will be described. Fig. 4 is a schematic plan view of an air-conditioned garment equipped with an air exhaust port adjustment mechanism according to the second embodiment when unfolded and viewed from the inside, Fig. 5 is a schematic plan view of a first adjustment belt and a second adjustment belt in the air exhaust port adjustment mechanism according to the second embodiment, and Fig. 6 is a schematic view showing a state in which an air-conditioned garment having an air exhaust port formed by the air exhaust port adjustment mechanism according to the second embodiment is viewed from above. In the second embodiment, components having the same functions as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0036] As shown in Fig. 4, the air exhaust port adjustment mechanism 50a of the second embodiment is provided in an air-conditioned garment 1 having a normal collar portion 2a that can be folded back. Here, Fig. 4 shows the collar portion 2a in a state where the folded back portion P is not folded back and is spread out. Also, Fig. 6 shows the collar portion 2a without the folded back portion P. In the second embodiment, the air exhaust port adjustment mechanism 50a is provided not in the center of the collar portion 2a (back collar portion 12) but in a predetermined location around the back collar portion 12, specifically, in a location slightly below the back collar portion 12. This is because, although it depends on the shape of the air-conditioned garment, in normal air-conditioned garments, in order to smoothly exhaust air circulating in the air flow passage to the outside from the air exhaust port, it is more reasonable to provide the air exhaust port slightly below the back collar portion 12 rather than at the back collar portion 12.

[0037] The air exhaust port adjustment mechanism 50a of the second embodiment includes a first adjustment belt 51a and a second adjustment belt 53, as shown in Fig. 4, Fig. 5, and Fig. 6. As shown in Fig. 5(a), the first adjustment belt 51a includes a first belt-shaped member 511a and a fastener 512 provided at one end of the first belt-shaped member 511a. In the second embodiment, a button is used as the fastener 512. The other end of the first belt-shaped member 511a is an attachment portion 513 for attachment to a predetermined first position around the back collar 12 on the inner surface of the fabric of the air-conditioned clothing 1. Here, the first adjustment belt 51a is positioned so that the fastener 512 faces the inner surface of the fabric of the air-conditioned clothing 1 and the longitudinal direction of the first belt-shaped member 511a is approximately parallel to the longitudinal direction of the collar 2a, and the attachment portion 513 of the first belt-shaped member 511a is sewn to the first position.

[0038] As shown in FIG. 5(b), the second adjustment belt 53 has a second belt-shaped member 531 and a through hole 532 formed at one end of the second belt-shaped member 531 for engaging with the fastener 512 to attach the fastener 512. It is preferable to use a strong cloth as the second belt-shaped member 531. The through hole 532 corresponds to the engagement portion of the present invention. This through hole 532 is a buttonhole made by making a cut line. The cut direction of this buttonhole is approximately parallel to the longitudinal direction of the second belt-shaped member 531. The other end of the second belt-shaped member 531 is an attachment portion 533 for attachment to a predetermined second position around the back collar 12, which is on the inner surface of the fabric of the air-conditioned clothing 1 and is different from the first position to which the first adjustment belt 51a is attached. Here, the second adjustment belt 53 is positioned so that the longitudinal direction of the second belt-shaped member 531 is approximately parallel to the longitudinal direction of the collar 2a and the through-hole 532 is located on the side of the first adjustment belt 51a, and the attachment portion 533 of the second belt-shaped member 531 is sewn to the second position. Therefore, when the second adjustment belt 53 is attached to the inner surface of the fabric of the air-conditioned clothing 1, the cutting direction of the buttonholes becomes approximately parallel to the longitudinal direction of the back collar 12.

[0039] Thus, in the second embodiment, instead of directly forming the through hole 532 in the fabric of the air-conditioning clothing 1, the second adjustment belt 53 is attached to the inner surface of the fabric of the air-conditioning clothing 1, and the through hole 532 is provided in this second adjustment belt 53. This is for the following reasons. That is, the part slightly below the rear part of the collar 12 where the air discharge port mechanism 50a is provided is usually composed of a single piece of cloth, unlike the collar part 2a. If a through hole is directly provided in this part, sufficient strength cannot be obtained at this part, and moreover, when the fastener is attached to the through hole, the fastener will be exposed outside the air-conditioning clothing, damaging the appearance.

[0040] Now, let the length of the first adjustment belt 51a from the attachment part 513 of the first belt-like member 511a to the fastener 512 be L3, the length of the second adjustment belt 53 from the attachment part 533 of the second belt-like member 531 to the through hole 532 be L4, and the distance along the fabric of the air-conditioning clothing 1 from the first position (attachment part 513 of the first belt-like member 511a) where the first adjustment belt 51a is attached to the second position (attachment part 533 of the second belt-like member 531) where the second adjustment belt 53 is attached be L5. The lengths of the first adjustment belt 51a and the second adjustment belt 53, and the above-mentioned first position and second position are designed such that L3 + L4 < L5. That is, the total length of the length L3 of the first adjustment belt 51a from the attachment part 513 of the first belt-like member 511a to the fastener 512 and the length L4 of the second adjustment belt 53 from the attachment part 533 of the second belt-like member 531 to the through hole 532 is shorter than the distance L5 along the fabric of the air-conditioning clothing 1 from the first position where the first adjustment belt 51a is attached to the second position where the second adjustment belt 53 is attached.

[0041] When the fastener 512 is passed through the through hole 532 and fastened, as shown in FIG. 6, the inner surface of the fastener 512 comes into contact with the outer surface of the second adjustment belt 53 at the portion where the through hole 532 is formed, and the fastener 512 is firmly fixed to the second adjustment belt 53. At this time, the vicinity of the rear collar 12 of the air-conditioned clothing 1 loosens, and the air exhaust port 13 is formed between the rear collar 12 and the rear neck of the wearer. Also, if it is desired to exhaust a small amount of air from the air exhaust port 13, the fastener 512 is not attached to the through hole 532. In this case, a certain amount of opening is automatically secured between the rear collar 12 and the rear neck due to the pressure of the air flowing through the air flow passage, and this opening becomes the air exhaust port 13 from which a small amount of air can be exhausted to the outside. Therefore, by using the air exhaust port adjustment mechanism 50a of the second embodiment, the wearer can select the opening degree of the air exhaust port 13 from two levels of opening degrees according to the purpose of use of the air-conditioned clothing 1, and obtain the desired cooling effect.

[0042] Next, a method for producing the air outlet adjustment mechanism 50a of the second embodiment will be described. First, on the inner surface of the collar 2a of the air-conditioned clothing 1, a first crease line is drawn at a first position where the first adjustment belt 51a is to be attached, and a second crease line is drawn at a second position where the second adjustment belt 53 is to be attached. Next, a first belt-shaped member 511 and a second belt-shaped member 531 are prepared, a button is attached as a fastener 512 to one end of the first belt-shaped member 511, and a through-hole 532 is formed in one end of the second belt-shaped member 531 by a method similar to that for forming a normal buttonhole. Here, the cutting direction of the buttonhole is approximately parallel to the longitudinal direction of the second belt-shaped member 531.

[0043] Next, the first adjustment belt 51a is positioned so that the fastener 512 faces the inner surface of the fabric of the air-conditioned clothing 1 and the longitudinal direction of the first belt-shaped member 511a is approximately parallel to the longitudinal direction of the collar portion 2a, and the attachment portion 513 of the first belt-shaped member 511a is sewn to the location indicated by the first score line. The second adjustment belt 53 is positioned so that the longitudinal direction of the second belt-shaped member 531 is approximately parallel to the longitudinal direction of the collar portion 2a and the through hole 532 is located on the side of the first adjustment belt 51a, and the attachment portion 533 of the second belt-shaped member 531 is sewn to the location indicated by the second score line. In this manner, the air exhaust port adjustment mechanism 50a of the second embodiment can be easily produced.

[0044] The air exhaust port adjustment mechanism of the second embodiment comprises a first adjustment belt having a fastener provided on one end of a first belt-shaped member, the other end of which is attached to a first predetermined position around the back collar on the inner surface of the fabric of the air-conditioned clothing, and a second adjustment belt having a through hole formed on one end of a second belt-shaped member for engaging with and attaching the fastener, the other end of which is attached to a second predetermined position around the back collar on the inner surface of the fabric of the air-conditioned clothing different from the first position where the first adjustment belt is attached, wherein the total length of the first adjustment belt from the other end of the first belt-shaped member to the fastener and the length of the second adjustment belt from the other end of the second belt-shaped member to the through hole is shorter than the distance along the fabric of the air-conditioned clothing from the first position where the first adjustment belt is attached to the second position where the second adjustment belt is attached. Thus, by simply attaching the fastener to the through hole, slack can be secured near the back collar of the air-conditioned clothing, and an air exhaust port can be easily and reliably formed. In addition, the opening degree of the air exhaust port can be easily adjusted in two stages depending on whether the fastener is attached to the through hole or not. Furthermore, by providing the second adjustment belt having a through hole, when the fastener is attached to the through hole, the fastener remains inside the air-conditioned clothing and is not visible from the outside, so the appearance is not marred.

[0045] In addition, in the air exhaust port adjustment mechanism of the second embodiment, the buttonhole is formed so that the cut direction of the buttonhole is approximately parallel to the longitudinal direction of the back collar, so that when a button is used as a fastener and the button is attached to the buttonhole, even if a pulling force is applied to the first adjustment belt, the button will not easily come off the buttonhole. Moreover, by using a strong cloth as the second belt-shaped member, even if forces are applied to the button and the buttonhole from various directions, the buttonhole will not easily open and the button will not come off the buttonhole. Furthermore, in the air exhaust port adjustment mechanism of the second embodiment, only one through hole is formed, but in this case, if the through hole is provided in advance at a position that optimizes the opening degree of the air exhaust port, the wearer can optimize the opening degree of the air exhaust port without hesitation by simply attaching the fastener to the through hole. The other effects are the same as those of the first embodiment.

[0046] [Other embodiments] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the present invention.

[0047] For example, in the above first embodiment, the air exhaust port adjustment mechanism is provided at the rear collar of the air-conditioned clothing, but the air exhaust port adjustment mechanism of the first embodiment may be provided around the rear collar of the air-conditioned clothing. Also, in the above second embodiment, the air exhaust port adjustment mechanism is provided around the rear collar of the air-conditioned clothing, but the air exhaust port adjustment mechanism of the second embodiment may be provided at the rear collar of the air-conditioned clothing.

[0048] In the above first embodiment, two through holes are provided at the rear of the collar of the air-conditioned clothing, but only one or three or more through holes may be provided at the rear of the collar of the air-conditioned clothing. Furthermore, in the above second embodiment, one through hole is provided at the second adjustment belt, but two or more through holes may be provided at the second adjustment belt. The more through holes are provided, the more finely the opening degree of the air exhaust port can be adjusted.

[0049] In the above first embodiment, the adjustment belt is configured with a belt-like member, but the adjustment belt may be configured with a string-like member instead of a belt-like member. Similarly, in the above second embodiment, the first adjustment belt and the second adjustment belt are configured with a belt-like member, but the first adjustment belt may be configured with a string-like member, and the second adjustment belt may be configured with a string-like member. Furthermore, in the above second embodiment, due to the structure of the air-conditioned suit, there may be a cloth around the collar, and in this case, this cloth may be used as the second adjustment belt.

[0050] Furthermore, in the above embodiments, a button is used as the fastener and a button hole is used as the through hole (engagement portion), but the present invention is not limited to this, and a dedicated fastener may be used. In this case, by using an engagement portion that corresponds to the dedicated fastener, convenience when attaching the fastener to the engagement portion is further improved. For example, a hook-and-loop fastener may be used as the fastener and the engagement portion, or various hooks or hooks made of metal or resin may be used.

[0051] In addition, in the first embodiment, the end of the belt-shaped member opposite the end where the fastener is provided may be removably attached to the fabric of the air-conditioned clothing. Similarly, in the second embodiment, the end of the first belt-shaped member opposite the end where the fastener is provided may be removably attached to the fabric of the air-conditioned clothing, and the end of the second belt-shaped member opposite the end where the through hole is formed may be removably attached to the fabric of the air-conditioned clothing. This allows the air exhaust port adjustment mechanism to be removed from the air-conditioned clothing, so that the air-conditioned clothing and the air exhaust port adjustment mechanism can be washed without any problems. Furthermore, when the air exhaust port adjustment mechanism breaks, it can be easily replaced with a new air exhaust mechanism. [Industrial Applicability]
