Description

Technical Field

[0001] The present invention relates to an air-conditioned garment that cools the body by generating a flow of air substantially parallel to the surface of the body or an undergarment worn on the body.

Background Art

[0002] In recent years, air-conditioned garments for cooling the body have been put into practical use and are rapidly spreading. A conventional air-conditioned garment 101 includes a garment body 110 sewn from a material with low air permeability, two fans 140, 140 attached below the lower rear side of the garment body 110, a power supply device (not shown) for supplying power to the two fans 140, 140, and a power cable (not shown) for electrically connecting the power supply device and the two fans 140, 140.

[0003] When the fan 140 is operated, a large amount of air is taken into the garment body 110 from the fan 140. Due to the pressure of the taken-in air, an air flow passage is automatically formed between the garment body 110 and the body or the undergarment, and the taken-in air flows upward along the surface of the body or the undergarment through the formed air flow passage and is discharged to the outside, for example, around the collar portion or from the cuff portions. Here, the areas around the collar portion and the cuff portions serve as air discharge portions 130. Then, while the air flows through the air flow passage between the garment body 110 and the body or the undergarment, it evaporates the sweat that has come out of the body, and the body is cooled by the heat of vaporization during evaporation (see, for example, Patent Document 1).

[0004] By the way, in high-place work such as at a construction site, for the prevention of falling accidents, for example, as shown in FIGS. 8(a) and (b), a harness-type safety belt HN81 in which a wire WR81 having a hook HK81 at the tip is connected to the upper back is mainly used. By hooking the hook HK81 on a fixed object, even if a worker accidentally steps off, the wire WR81 serves as a lifeline and safety measures are taken to prevent falling to the ground or the like. Conventionally, such a harness-type safety belt HN81 has been worn over the air-conditioned garment 101.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when the harness-type seat belt HN81 is worn over the conventional air-conditioned clothing 101, there is a problem that the air flow path between the fabric of the air-conditioned clothing 101 and the body is blocked by the belt of the harness-type seat belt HN81, resulting in a sharp reduction in the cooling effect.

[0007] An object of the present invention is to provide an air-conditioned clothing for high-altitude work that can exhibit a cooling effect even when a harness-type seat belt is worn.

Means for Solving the Problems

[0008] To achieve the above object, the present invention provides a clothing body made of a sheet-like material having little or no air permeability and covering at least the upper body of the body, the clothing body having an air discharge portion, and a fan attached so as to cover an opening provided in the clothing body, the fan taking in air from the outside and forcibly generating an air flow in the space between the clothing body and the body or underwear, wherein the clothing body has an opening / closing means for opening and closing a hook through-hole formed in the upper back portion, a bendable cylindrical wire penetration means having one end attached to the clothing body so as to surround the opening / closing means and the other end provided with an air leakage prevention means, the wire penetration means having little or no air permeability, and is characterized by being an air-conditioned clothing having the above.

[0009] In the clothing body of the air-conditioned clothing of the present invention, there is an opening / closing means for opening and closing a hook through-hole formed in the upper back part, and one end is joined to the back surface of the clothing body so as to surround the opening / closing means, and an air leakage prevention means is provided at the other end, and a bendable cylindrical wire penetration means with low air permeability or no air permeability is provided. Therefore, even when worn over a harness-type safety belt, there is no air leakage from the vicinity of the wire passing through the wire penetration means of the clothing body, and a sufficient cooling effect as an air-conditioned clothing can be obtained. Further, since the wire penetration means is made of a flexible sheet-like material, during work without using a harness-type safety belt, the wire penetration means can be stored inside the clothing body, and by closing the opening / closing means, it can be used as a normal air-conditioned clothing.

Effects of the Invention

[0010] According to the present invention, even when wearing a safety belt with a fall prevention wire attached, an air-conditioned clothing can be worn over it, and air leakage from the wire penetration means through which the wire passes can be prevented, so that the cooling effect as an air-conditioned clothing can be exhibited.

Mode for Carrying Out the Invention

[0012] (Embodiment) Hereinafter, with reference to the drawings, embodiments for carrying out the invention according to the present application will be described. However, the scope of the invention is not limited to the illustrated examples.

[0013] As shown in FIGS. 1 and 2, the air-conditioning clothing 1 of the present embodiment includes a clothing body 10, fans 4, 4, a power supply device (not shown), and a power cable (not shown).

[0014] The clothing body 10 is made of a sheet-like material with little or no air permeability and is formed in a shape that covers the upper body and arms. For example, in the present embodiment, the clothing body 10 is made in the shape of a blouson-type upper garment. The clothing body 10 is provided with a first opening / closing means 11 on the front body, two opening holes 14, 14, a first air leakage prevention means 13 at the hem, an air discharge part 12 formed at the cuffs and the collar part, a second opening / closing means 15 provided at the upper back part, and a wire penetration means 2. The first opening / closing means 11 on the front body is for opening and closing the front part of the clothing body 10 when wearing the clothing body 10. Here, a fastener is used as the first opening / closing means 11 on the front body.

[0015] Each of the two opening holes 14 is formed at a predetermined part of the clothing body 10, specifically, at a part corresponding to the left and right waists. And a fan 4 is attached to the opening hole 14. That is, the part of the clothing body 10 around the opening hole 14 serves as a fan attachment part.

[0016] The first air leakage prevention means 13 at the hem is provided at a predetermined end of the clothing body 10 to prevent air in the space between the clothing body 10 and the body or the undergarment from leaking to the outside from the end. In this embodiment, an elastic member such as a rubber string is provided at the hem of the clothing body 10. For this reason, the hem of the clothing body 10 is narrowed by the elastic member and comes into close contact with the body or the undergarment.

[0017] As shown in FIG. 3, the second opening / closing means 15 is for opening and closing a hook through-hole HL31 provided at the upper back of the back body, and is the opening / closing means in the present invention. Here, a fastener is used in the same manner as the first opening / closing means 11 at the front body.

[0018] As shown in FIGS. 2 and 3, the wire penetrating means 2 is formed into a cylindrical shape by a sheet-like material having low air permeability or no air permeability or flexibility (foldable) with one end joined to the back surface of the fabric so as to surround the second opening / closing means 15 that opens and closes the hook through-hole HL31 provided at the upper back, and the second air leakage prevention means 23 provided at the other end. Also, as the material of the wire penetrating means 2, the same material as that of the clothing body 10 may be used, or any material such as another material (for example, vinyl, etc.) having low air permeability or no air permeability or flexibility (foldable) may be used.

[0019] The wire penetrating means 2 will be described more specifically. The perimeter of the end (inner end TM31) joined to the back surface of the fabric at the upper back is sufficiently longer than twice the length FL of the second opening / closing means 15, the perimeter of the other end (outer end TM32) is shorter than the perimeter of the inner end TM31, and the length L from the inner end TM31 to the outer end TM32 (the total length of the wire penetrating means 2 excluding the portion joined to the back surface of the fabric) has a length sufficient to form the second air leakage prevention means 23 described later. Also, for example, the perimeter of the inner end TM31 and the perimeter of the outer end TM32 have a length through which a hook HK81 connected by a wire WR81 to the upper back of the harness-type seat belt HN81 can pass.

[0020] Next, the second air leakage prevention means 23, which is the air leakage prevention means of the present invention, will be described. Around the outer end portion TM32, a string passage portion 231 having an outlet for a string 232 (or a cord) to pass through is formed. A string 232 longer than the length around the outer end portion TM32 is passed through, and a cord stopper 233 is provided at the portion of the string 232 protruding outside from the outlet, so that the outer end portion TM32 can be closely attached to the wire.

[0021] Since the wire penetration means 2 is made of a flexible sheet-like material, it can be stored inside the clothing body 10, and the fastener, which is the second opening / closing means 15, can be closed. Also, the second opening / closing means 15 can be opened, and most of the portion of the wire penetration means 2 that is not joined to the back surface of the clothing body 10 can be pulled out to the outside.

[0022] Subsequently, the procedure for wearing the air-conditioning clothing 1 of the present invention over the harness-type seat belt HN41 will be described.

[0023] First, the harness-type seat belt HN41 is worn in the normal procedure. Then, the second opening / closing means 15 at the upper back portion of the air-conditioning clothing 1 is opened, the outer end portion of the wire penetration means 2 is pulled out to the outside, and the hook HK41 is pulled out to the outside from the inside of the air-conditioning clothing 1 through the wire penetration means 2. For example, in the case of this embodiment, since the perimeter of the outer end portion TM32 is 200 mm, a hook with a width of up to about 90 mm can be passed through. Then, the string 232 passed through the string passage portion 231 formed in the outer end portion TM32 of the wire penetration means 2 is locked by the cord stopper 233 so that there is no gap for air leakage between the wire WR41 and the edge of the outer end portion TM32. Finally, the air-conditioning clothing 1 through which the wire WR41 has passed is worn, and the wire WR41 is pulled taut so that there is no slack inside the air-conditioning clothing.

[0024] Next, the effects of the air-conditioned clothing 1 will be described. Since the wire WR41 with the hook HK41 at the tip penetrates the air-conditioned clothing 1, even when the harness-type safety belt HN41 is worn and the air-conditioned clothing 1 is worn over it, the hook HK41 can be hooked at an appropriate place to ensure safety.

[0025] Also, the outer end portion TM32 of the wire penetration means 2 and the wire WR41 are in close contact with each other by the second air leakage prevention means 23. For this reason, even when the air-conditioned clothing 1 is operated, there is no air leakage from the close contact portion. Therefore, a large amount of air is taken into the clothing body 10 by the fan 4 as in a normal air-conditioned clothing, and the automatically formed air flow path circulates upward along the surface of the body or the undergarment and is discharged from the air discharge portion 12. Thus, sweat can be efficiently evaporated and the body can be cooled.

[0026] Note that, for safety reasons, there is no large variation in the position of the wire WR41. However, although the position of the wire WR41 varies somewhat vertically due to the relationship between the body shape of the user and the size of the harness-type safety belt HN41, etc., the wire penetration means 2 is formed long vertically, so the variation can be absorbed and it can be used. For example, the length FL of the second opening / closing means 15 is 150 mm, and it can absorb the variation in the position of the wire WR41.

[0027] Also, the user may not always wear the harness-type safety belt HN41 and may also perform work (normal work) without using the harness-type safety belt HN41. The usage method when performing normal work from the state after using the harness-type safety belt HN41 in this case (the second opening / closing means 15 is open and the wire penetration means 2 protrudes outward) will be described.

[0028] First, the wire penetration means 2 that has protruded outward is pushed into the inside of the clothing body 10 through the opening of the opened second opening / closing means 15 on the back upper part to close the second opening / closing means 15. Thereby, the wire penetration means 2 is housed inside the air-conditioned clothing 1 and can be used as a normal air-conditioned clothing.

[0029] (Modification example) When the air - conditioned clothing 1 of the embodiment is used for normal work, the wire penetration means 2 housed inside the clothing body 10 may block the air flow path between the body or the undergarment and the fabric of the air - conditioned clothing 1, and the cooling capacity may be partially deteriorated. In the modification example, as shown in FIG. 5, on the back side of the upper back, a flat bag - shaped storage portion 16 for storing the wire penetration means 2 along the second opening / closing means 15 is formed, and the wire penetration means 2 made of a flexible sheet - like material can be folded flat and stored.

[0030] Since it is configured as described above, by storing the wire penetration means 2 in the storage portion 16 and closing the second opening / closing means 15, it becomes almost the same state as a normal air - conditioned clothing, and the air flow in the relevant part is not obstructed by the stored wire penetration means 2, and a cooling effect equivalent to that of a normal air - conditioned clothing can be realized.

[0031] (Modification example 2) In the second modification example, as shown in FIG. 6, on the back side of the upper back, fixing means 17 for folding and fixing the wire penetration means 2 along the second opening / closing means 15 in a small size is formed, and the wire penetration means 2 made of a flexible sheet - like material can be folded several times to make it small and fixed. For example, the fixing means 17 may use a member such as a hook - and - loop fastener or a button that can be easily attached and detached.

[0032] Since it is configured as described above, by folding the wire penetration means 2 small and fixing it with the fixing means 17 and closing the second opening / closing means 15, it becomes almost the same state as a normal air - conditioned clothing, and the air flow in the relevant part is not obstructed by the stored wire penetration means 2, and a cooling effect equivalent to that of a normal air - conditioned clothing can be realized.

[0033] Note that the present invention is not limited to the above - described embodiments and modification examples, and various modifications are possible within the scope of the gist thereof.

[0034] In addition, in the present embodiment and its modifications, the case where the harness-type seat belt HN41 is used has been described. However, not only the harness-type seat belt HN41 but also any fall prevention device in which a wire is connected to the upper back can be used.

[0035] In addition, in the present embodiment and its modifications, the case where a fastener is used as the opening / closing means 15 has been described. However, the second opening / closing means 15 is not limited to a fastener, and general means such as a hook-and-loop fastener or a button can also be used.

[0036] In addition, in the present embodiment and its modifications, the case where the second air leakage prevention means 23 forms a string passage portion 231 at the outer end portion TM32 and uses the string 232 and the cord stopper 233 has been described. However, the second air leakage prevention means 23 is not limited to this, and for example, various general methods such as attaching a belt and a hook-and-loop fastener to the outside of the outer end portion TM32 to eliminate the gap with the wire WR41 can be used.

[0037] In addition, in the present embodiment and its modifications, the wire penetration means 2 is housed inside the clothing body 10, but the wire penetration means 2 may be detachable. In this case, when not in use, by removing the wire penetration means 2 from the clothing body 10, the wire penetration means 2 does not get in the way, and by closing the second opening / closing means 15, it becomes the same state as a normal air-conditioning clothing, and the air circulation is not hindered, and a cooling effect equivalent to that of a normal air-conditioning clothing can be realized.

[0038] Furthermore, in the above embodiment, the case where the clothing body 10 is made in the shape of a blouson-type upper garment has been described. However, the clothing body can be made in a shape that covers the lower body as well, such as a one-piece dress shape. In this case, the air leakage prevention means 13 at the hem is not necessarily required. When the air leakage prevention means 13 at the hem is not provided, the air introduced by the fan 4 also circulates to the lower body and is discharged from the hem opening at the feet.

[0039] As described above, the air-conditioned clothing according to the present invention is suitably used as air-conditioned clothing worn over a safety belt to which a wire for preventing a fall is attached.
