Cooling clothes

Abstract

If you sweat profusely on your back, condensation may form on the tube, which can make your clothes damp and uncomfortable for some people. [Solution] When the pump 79 is operated, cooled water circulates inside the tube 67. The tube 67 is exposed on the lining 31 side, and the exposed part of the body is cooled through the tube 67. Air is blown out from the central outlet 43 on the back side by the airflow created by the operation of the fan 51, and this air hits the outer surface of the tube 67. If a large amount of sweat is produced on the back side, condensation may form on the tube 67, but this condensation absorbs heat of vaporization from the body side and evaporates, and is expelled by the airflow of air that is blown out one after another. Therefore, the condensation is removed. Furthermore, since the removal of condensation is carried out by absorbing heat of vaporization from the body side and evaporating, a further cooling effect on the body side can be expected.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In this type of cooling clothing, when a large amount of sweat is generated especially on the back side, condensation may occur on the tubes, and in that case, some people may feel uncomfortable due to the clothes getting wet. On the other hand, although there has been conventional cooling clothing of the type of Patent Document 2, it is difficult to obtain a sufficient cooling effect in a very high-temperature place.

[0005] The present invention has been made to solve the above problems, and while making use of the mechanism in which the body side is cooled by laying tubes on the inner surface of the upper garment in an exposed state and aligning the body side with the tubes through which cooling water circulates, it can quickly remove the condensation on the surface of the tubes on the back side, and by taking the heat of vaporization from the body side to vaporize the removed condensation, a further cooling effect on the body side can be expected, and an object thereof is to provide a novel and useful cooling clothing. [Means for solving the problem]

[0006] The present invention was made to solve the above problems, and is a cooling garment comprising a jacket body that encloses the body when worn, a lining provided on the back side of the jacket body which is made of overlapping windproof fabric and mesh fabric, with holes in the windproof fabric at the central air outlet near the back which are open to the outside through the mesh fabric, and a tube through which a cooling fluid circulates running along the exposed side of the lining including the central air outlet, and a fan attached to the jacket body side, and an airflow formed by the operation of the fan which is blown out from the central air outlet and hits the tube.

[0007] Preferably, the jacket body has left and right ducts formed on both sides using the lining as part of the back side of the jacket body and opening at the upper neck area, through openings formed in the left and right ducts and passing through around the armpits, a central air outlet at the back area formed on part of the back side of the jacket body so that the enveloping side is ventilated, and a connecting part that connects the left and right ducts and the central air outlet, and a fan is attached to the duct-forming part of the jacket body, and the airflow formed by the operation of the fan is distributed, some of which is ejected from the through openings, some of which rises up the left and right ducts and is blown out from the upper openings, and the remainder is blown out from the central air outlet via the connecting part.

[0008] Preferably, a fingertip insertion hole is provided near the fan mounting area of ​​the duct, which can be opened and closed.

[0009] Preferably, the back of the jacket is provided with a waterproof pocket that can be opened and closed from the outside and also opens at at least one shoulder, and a cooling container containing a cooling fluid circulating through a tube is housed in it.

[0010] Preferably, the hydration system is portable with its refill pouch stored in a waterproof pocket, and the hose connected to the refill pouch extended from the opening.

[0011] Preferably, the main body of the jacket is constructed in a vest style, with the back and front panels connected via the shoulders, and the left and right ducts and the central outlet are formed on the back panel side. [Effects of the Invention]

[0012] The cooling garment of the present invention utilizes a mechanism in which a tube is laid exposed on the back of the garment, and the body is cooled by aligning the body side with the tube through which cooling water circulates. This allows for the rapid removal of condensation on the surface of the tube on the back, and further cooling effects on the body can be expected by removing the condensation by absorbing heat of vaporization from the body side. Furthermore, although the fan draws in air from the outside, it is possible to configure it so that only the back side of the body and the jacket circulates for a short time while the surroundings are open. If configured in this way, the jacket will not bulge outwards due to the air drawn in. [Brief explanation of the drawing]

[Figure 6] This is a schematic exploded perspective view of the cooling vest, seen from a different direction than Figure 5. [Figure 7]FIG. 1 is a perspective view of the cooling vest with the hydration system attached thereto.

BEST MODE FOR CARRYING OUT THE INVENTION

[0014] The cooling clothing according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 7, the cooling clothing is a vest-shaped cooling vest 1, and the outer fabric serving as the outer surface thereof is made of a synthetic fiber fabric such as nylon or polyester and is configured to be windproof. This outer fabric corresponds to the upper body 3. The back part 5, the left front part 7, and the right front part 9 of the upper body 3 are connected via the shoulders. The part between the left front part 7 and the back part 5 and the part between the right front part 9 and the back part 5 are each connected by a belt 11, and the part between the left front part 7 and the right front part 9 is also connected by a similar belt 13.

[0015] The back part 5 is cut into a tongue shape upward, and a flap-shaped lid part 15a of the storage pocket 15 is formed. The opening edge 15b is opened and closed by a fastener. Reference numeral 19 denotes a partition fabric. This partition fabric 19 has an inverted U-shaped contour excluding the part of the flap-shaped lid part 15a from the back part 5. The partition fabric 19 is overlapped with the back part 5 with their edges aligned, and the edges of the partition fabric 19 are sewn to the back part 5 except for the neck edge 19a. Therefore, between the unsewn neck edge 19a and the back part 5, there is a neck opening 21. The partition fabric 19 forms a tubular shape together with the back part 5. In the part where it is sewn into a tubular shape, the width dimension of the partition fabric 19 in the left-right direction is set larger than the width dimension of the back part 5 in the left-right direction, so that a sufficient space is created inside the tube when it is sewn into a tubular shape.

[0016] On the back side, a pocket fabric 15c having the same contour as the back part 5 is overlapped with the back part 5 with their edges aligned and the edges are sewn. The part overlapping the partition fabric 19 is sewn to the back part 5 together with the partition fabric 19. However, on the shoulder side of the pocket fabric 15c, it is not sewn to the upper body main body 3 (and the partition fabric 19), and there is an opening between the pocket fabric 15c and the upper body main body 3 (and the partition fabric 19). Also, at the part of the neck edge 19a, the pocket fabric 15c is only sewn to the partition fabric 19, and the neck opening 21 between the partition fabric 19 and the back body 5 is secured. Using the pocket fabric 15c, a storage pocket 15 is formed. This storage pocket 15 opens with a flap-shaped lid 15a.

[0017] On the left and right front body parts 7, 9 of the upper body main body 3, cut openings 7a, 9a are respectively formed. Also, as described above, on the shoulder side of the pocket fabric 15c, there is an opening between the pocket fabric 15c and the upper body main body 3 (and the partition fabric 19). Therefore, the inside of the storage pocket 15 opens outward of the cooling vest 1 with the flap-shaped lid 15a and the openings 7a, 9a. The inner surface of the storage pocket 15 is laminated with a waterproof sheet to be waterproof. On the inner surface of the flap-shaped lid 15a of the storage pocket 15, a patch pocket 15d that opens upward is provided by pasting a net-like sheet. Inside the storage pocket 15, a hanging belt 15e is provided. A snap is attached to this hanging belt 15e. When folded back and snapped, it becomes annular, and it can be hung by the annular part. Also, a storage pocket 17 is formed using a pocket fabric 17a in the same manner as the storage pocket 15. The opening 17b of this storage pocket 17 is also opened and closed with a fastener, but it is not waterproof. Also, when viewed from the outside, the storage pocket 15 and the storage pocket 17 appear to be arranged vertically. However, the inside of the storage pocket 15 reaches near the lower end of the upper body main body 3, and the storage pocket 17 overlaps from the outside side at the lower part of the storage pocket 15.

[0018] The back panel 5 bulges outward on the left and right sides at the bottom, extending to the area under the armpits when worn. In this area, circular fan mounting holes 23, 23 are formed, respectively, to serve as fan mounting points. Near the top of the fan mounting holes 23, there is a section with a slit that opens and closes from the surface with a zipper. When this slit is spread flat, it becomes a hole. This slit forms the hand insertion hole 25. Additionally, a detachable hood (27) is attached to the back of the garment (5) using buttons.

[0019] On the reverse side of the pocket fabric 15c, an insulating sheet 29 with a similar outline to the pocket fabric 15c is overlapped with the pocket fabric 15c (and the partition fabric 19 and the back body 5) with its edges aligned, and its edges are sewn in place. However, on the shoulder side of the pocket fabric 15c, it is sewn only to the pocket fabric 15c, and an opening is maintained between the pocket fabric 15c and the main body of the jacket 3. Similarly, the neck opening 21 is also secured at the neck edge 19a.

[0020] Furthermore, reference numeral 31 indicates the lining, which has the same outline as the main body of the jacket 3. This lining 31 is made of a breathable mesh fabric. A windproof fabric 33, which has the same outline as the lining 31, is overlapped with it, with their edges aligned. In this windproof fabric 33, a large square cutout is made in the center of the back area when worn, forming the cutout hole 33a. Furthermore, a net sheet 35 is layered over the windproof fabric 33 so as to surround the notch 33a. Except for the area of ​​the notch 33a, the lining 31, windproof fabric 33, and net sheet 35 are layered together, and the lining 31 forms the inner surface of the cooling vest 1 and comes into contact with the body when worn. The lining 31 and the windproof fabric 33 are overlapped with their edges aligned, and the edges are sewn together. In addition, the edges of the net sheet 35 are sewn to the windproof fabric 33.

[0021] The lining 31 (and windproof fabric 33 and net sheet 35) is overlapped on the back side of the main body 3 of the jacket (and partition fabric 19, pocket fabric 15c, and insulation sheet 29), with the edges aligned, and the edges are sewn together to form a single unit. However, the stitching is designed not to affect the opening configuration on the main body 3 of the jacket, and on the shoulder side of the pocket fabric 15c, it is sewn only to the pocket fabric 15c, ensuring that the opening between the pocket fabric 15c and the main body 3 of the jacket is maintained. Similarly, the neck opening 21 is also secured at the neck edge 19a.

[0022] As described above, the lower left and right sides of the back panel 5 bulge outwards, and fan mounting holes 23 and hand insertion holes 25 are formed in these left and right sections, respectively. The partition fabric 19, pocket fabric 15c, insulation sheet 29, windproof fabric 33, and lining 31 also bulge outwards to the left and right, corresponding to the bulges on the left and right sides of the back panel 5. In the bulging portion of the partition fabric 19, a long, narrow rectangular through-hole 37a and a circular communication hole 39a are formed at intervals. The communication hole 39a is smaller than the fan mounting hole 23.

[0023] Similarly, the pocket fabric 15c, insulation sheet 29, windproof fabric 33, and lining 31 also have through-holes 37b, 37c, 37d, and 37e formed in the same positions. The edges of each of these openings are then sewn together to form a single through-hole 37. This through-hole 37 is open at the partition fabric 19 and lining 31, and is open to the outside through the lining 31. The gaps between adjacent fabrics and sheets of the overlapping partition fabric 19, pocket fabric 15c, insulation sheet 29, windproof fabric 33, and lining 31 are sealed by the edges of this through-hole 37.

[0024] Similarly, the pocket fabric 15c and the insulation sheet 29 also have connecting holes 39b and 39c formed in the same positions. The edges of each are sewn together to form a single connecting hole 39. This connecting hole 39 is open in the partition fabric 19 and the insulation sheet 29. The windproof fabric 33 adjacent to the insulation sheet 29 does not have a connecting hole, but it is open to the outside through the mesh of the net sheet 35, the notched holes 33a in the windproof fabric 33, and the mesh-like lining 31.

[0025] The main body of the jacket 3 is constructed as described above, forming a cylindrical shape enclosed by the partition fabric 19 and the back panel 5, and is closed at the lower end. The opening at the upper neck opening 21 is a duct 41. A pair of ducts 41, 41 are arranged on the left and right sides. A fan mounting hole 23 is formed on the jacket body 3 side of this duct 41, and a through-hole 37a and a communication hole 39a are formed on the partition fabric 19 side. The through-hole 37a is part of the through-hole 37 that penetrates the fabric of the main body of the jacket 3 in the direction of its thickness, and this through-hole 37 penetrates from inside the duct 41 toward the outside of the lining 31. The through-hole 37 is located in the area around the armpit when the main body of the jacket 3 is worn. The gap between the net sheet 35 and the insulation sheet 29 forms the central air outlet 43. This central air outlet 43 communicates with the inside of the duct 41 through a communication hole 39, which serves as a connecting section. It is also open to the outside through the mesh of the net sheet 35, the notched holes 33a of the windproof fabric 33, and the mesh-like lining 31, with the notched holes 33a located around the back.

[0026] Storage pockets 45 are provided at the bottom of the left and right front panels 7 and 9, respectively. These storage pockets 45 are formed in the same way as the storage pockets 17 described above, and the zippers open in an L-shape.

[0027] The jacket 49 is configured as described above, with the fan 51 attached to the fan mounting hole 23, forming the cooling vest 1. The fan 51 consists of a bottomed circular case and a lid that also serves as a protective guard, with the fan blades housed in the case. The lid is screwed onto the case to close it, and the flanges provided on each side press against the edge of the fan mounting hole 23, thereby attaching the fan 51 to the jacket 49. The user grasps the case with their fingertips, inserts it into the duct 41 through the fingertip insertion hole 25, and then, after the threaded portion protrudes from the fan mounting hole 23, the lid is screwed on from the outer side of the jacket 49. In this way, the presence of the fingertip insertion hole 25 makes it easy to install the fan 51.

[0028] The power cable 53 for the fan 51 is split into two at one end, with one end being longer. These two ends are connected to the fans 51 mounted on the left and right sides, respectively. The ducts 41, 41 are connected to the storage pocket 15 via small connecting holes, so the power cable 53 branches out within one duct 41 and enters the other duct 41 through the connecting holes. Within each duct 41, 41, it is detachably connected to the fans 51, 51. The other end of the power cable 53 is routed out through the opening 7a. The other end is then detachably connected to a battery 55 equipped with an operation button. The battery 55 is stored in a storage pocket 45 accessible from the outside of the jacket 49, allowing it to be turned on and off by operating the control buttons while wearing the jacket 49. The battery 55 also has a USB cable connector for charging.

[0029] On the jacket 49 side, as a feature of the present invention, a cooling fluid circulation mechanism is incorporated, which further utilizes tube 67 as a cooling section. Tube 67 is made of plastic and is flexible. On the exposed surface of the lining (mesh) 31, insertion guide portions 69, 69, ... formed by sewing both ends of elastic bands are arranged according to a specific pattern, and the tube 67 is sequentially inserted through the insertion guide portions 69, 69, ... and runs in a meandering manner. As a result, when the jacket 49 is worn, the tube 67 comes into contact with the body.

[0030] An insertion hole 71 is formed in the lining 31 of the part corresponding to the back panel 5. This insertion hole 71 is formed in the same way as the through-hole 37 and communicates with the inside of the storage pocket 15. Both ends of the tube 67 are inserted into the storage pocket 15 through the insertion holes 71. Insertion holes 71a, 71b, 71c, 71d, and 71e are formed at the same positions in the lining 31, windproof fabric 33, net sheet 35, insulation sheet 29, and pocket fabric 15c, and the edges of each hole are sewn together to form a single insertion hole 71. This insertion hole 71 opens on the exposed surface of the lining 31 and on the inner surface of the pocket fabric 15c. The storage pocket 15 contains a cooling bag 73 made of flexible plastic material with an opening at the top. This cooling bag 73 is sealed on three sides and formed into a long, rectangular flat bag. The opening of this bag is double-locked with a zipper and a fastener 75.

[0031] Furthermore, the cooling bag 73 is provided with a flap, and through holes 73a, 73a are formed in the flap. The belt portions that make up the annular parts of the suspension belts 15e, 15e are inserted through the through holes 73a, 73a, and then both are inserted through a single large through hole 75a formed in the fastener 75, and the bag is suspended in this state. This suspension prevents the cooling bag 73 from moving within the cooling pocket 15 even when the wearer of the cooling vest 1 moves. The cooling bag 73 contains a cooling container 77 that can be easily inserted and removed. As shown in Figure 1, the cooling body for cooling the water circulating in the tube 67 is composed of a cooling container 77 filled with a freezable liquid (water in this embodiment). The cooling container 77 is a flat, rectangular box shape. This cooling container 77 is made of rigid plastic (polyethylene (PE) in this embodiment), molded with thin walls into a flat, rectangular box shape, and is housed in an upright position.

[0032] The pump 79 is stored inside the storage pocket 17. The storage pocket 17 is connected to the storage pocket 15 via the insertion hole 17c. One end of the tube 67, which has entered the storage pocket 15 through the insertion hole 71, is connected to the cooling bag 73 at its upper end. The other end enters the storage pocket 17 through the communication hole 17c, where the pump 79 is attached. Further on, beyond the attachment point of the pump 79, the tube returns to the storage pocket 15 again through the communication hole 17c and is connected to the cooling bag 73 at its lower end.

[0033] Furthermore, the power cable 79a of the pump 79 also enters the storage pocket 15 again via the communication hole 17c and is pulled out through the opening 9a. It is then detachably connected to the battery 55. The battery 55 is used to power both the fan 51 and the pump 79.

[0034] Cooling vest 1 is configured as described above. When worn and fans 51, 51 are activated, the blades of fans 51, 51 rotate, drawing air from the outside of the jacket 49 into the ducts 41, 41 with force as an airflow. The duct 41 has a through-hole 37 formed on the inner side of the jacket 49, and since it is almost opposite the fan 51, as shown by the arrow, a portion of the intake air is ejected from the through-hole 37 as an air jet without losing momentum and before absorbing evaporative heat. Since the through-hole 37 is located on the underarm side, the air jet hits the sweaty underarm or the surrounding area, and the sweat is evaporated by evaporative heat from the underarm side. Therefore, you can feel the coolness directly from both underarms. Furthermore, the airflow rises through the duct 41 and is similarly blown out from the neck opening 21, hitting the neck. Therefore, you can feel the coolness directly from your sweaty neck. In this way, the air taken in by the operation of fan 51 is not wasted on convection but is distributed and directed directly as an airflow to areas where sweating is common, and the cooling effect on the body through the evaporation of sweat is efficiently realized.

[0035] Meanwhile, the remaining air from the left and right ducts 41, 41 enters the central outlet 43 through the connecting holes 39, 39. From this central outlet 43, the air escapes to the back through the mesh holes in the lining 31. This escaped air is blown out gradually between the jacket 49 and the body, as indicated by the arrow, similar to conventional fan-type cooling clothing.

[0036] At the same time, when the pump 79 is activated, cooled water circulates through the tube 67. The tube 67 is exposed on the lining 31 side, and the body side is cooled through the tube 67 at the exposed portion. On the back, as described above, air is blown out by the airflow created by the operation of fan 51, and this air hits the outer surface of tube 67. If you sweat a lot on your back, condensation may form on tube 67, in which case your clothes may become damp and uncomfortable. However, this condensation absorbs heat from the body and evaporates, and is expelled by the airflow that is continuously blown out. Therefore, the condensation is removed. Furthermore, since condensation is removed by absorbing heat of vaporization from the body, an additional cooling effect on the body can be expected.

[0037] In this way, by devising the structure of the jacket 49 to create ducts 41 and through-holes 37, it is possible not only to successfully solve the condensation problem on the back but also to obtain a cooling effect on the neck and underarms. The air cooling provided by fan 51 and the water cooling provided by tube 67 operate independently of each other, allowing for either air cooling only or water cooling only, depending on the situation. Because the jacket 49 does not inflate outwards due to the air taken in, it does not feel uncomfortable as a jacket. Also, because it does not inflate, a harness can be attached from the outside while wearing it, making it suitable for use in dangerous work at heights. Storage pockets 15, 17, and 45 can be used to store various small items such as wallets and smartphones, but storage pocket 15 on the back is particularly large, and jacket 49 can also be used as a backpack primarily for storage.

[0038] Furthermore, as shown in Figure 7, it can also be used to carry the hydration system 61. The hydration pouch 63 of the hydration system 61 is made of a flexible plastic material and is manufactured as a flat pouch with an opening at the top. Like the cooling pouch 73, it is locked with a zipper and fastener 75. This hydration pouch 63 is stored in the storage pocket 15. A detachable hose 65 is connected to the hydration pouch 63, but the storage pocket 15 is also open on the opening 9a side, and the hose 65 hangs down from there at the mouthpiece end. While wearing the system, the user can hydrate by removing the cap from the mouthpiece with a single touch and bringing it to their mouth to drink the water contained in the hydration pouch 63. Even when storing the cooling bag 73 along with the supply bag 63, it doesn't bulge, so carrying the hydration system 61 doesn't detract from the jacket's appearance 49. Furthermore, placing an ice pack in the 15d patch pocket will enhance the cooling effect.

[0039] Although embodiments of the present invention have been described in detail above, the specific configuration is not limited to these embodiments, and any design changes or other modifications that do not depart from the spirit of the invention are also included in the invention. For example, the shape of the jacket 49, the overlapping structure of the jacket body 3 and the lining 31, the materials of each, and the routing pattern of the tube 67 can be selected in various ways within the scope that achieves the objectives of the present invention.
