Description

[Technical Field]

[0001] The present invention relates to a dual-purpose cooling and heating garment that can be used in both hot and cold environments. [Background technology]

[0002] Working in a high-temperature environment, such as in the summer, makes it easy to sweat and suffer from heatstroke. To prevent this, as described in Patent Document 1, a cooling garment has been proposed that uses a rotating fan to draw in air from the outside and forcibly create an airflow between the body and the garment, thereby promoting the evaporation of sweat from the surface of the body and removing heat from the body. Furthermore, when working in cold environments such as winter, thermoregulatory responses such as peripheral vascular constriction and cold shivering occur to prevent a drop in body temperature, which in turn increases blood pressure, slows muscle movement, makes manual work difficult, and increases urination, leading to unnoticed dehydration.To prevent this, as described in Patent Document 2, a cold weather garment has been proposed that has an electric heating component attached to the garment and warms the garment with the heat generated by the electric heating component.

[0004] However, the above-mentioned clothing is customized for the specific purposes of cooling and protection from the cold, and if one intends to use it throughout the year, it is necessary to have separate cooling clothing and cold protection clothing. Recently, however, clothing has been increasingly used not only for business purposes but also for personal use in daily life, so there is room for improvement in terms of usability. Furthermore, when staying in a high-temperature environment for a long period of time, it is desirable to not only be able to constantly cool the body from the outside as a measure against heatstroke, but also to be able to replenish fluids as needed. Furthermore, depending on the type of work and the working conditions, such as on-site construction work, you may need to wear a protective jacket for safety reasons. Also, when working at heights, you must wear a harness. Even for personal use, you may need to carry a backpack. Therefore, it is convenient to have a jacket designed for light clothing.

[0005] The present invention was made in response to the above-mentioned conventional problems, and its object is to provide a new and useful cooling and heating garment that can be worn comfortably in both hot and cold environments, fully demonstrating its respective effects depending on the situation.

DETAILED DESCRIPTION OF THE INVENTION

[0010] A dual-purpose cooling and heating garment according to an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 to 5, the cooling and heating garment is a vest-shaped cooling and heating vest 1, a type of outerwear, in which the back body 5 of the vest body 3, which serves as the outer garment itself, is connected to the left and right front body sections 7 and 9 via the shoulders. The outer fabric 11 is made of a firm synthetic fabric such as nylon or polyester, and the lining 13 is made of a breathable, flexible fabric in which synthetic fibers such as polyester are woven into a mesh. Both are black, and the outer fabric 11 in particular is light-blocking. The outer fabric 11 and the lining 13 are sewn together at their respective outline edges to form a single unit. The lining 13 is a single continuous piece of fabric, while the outer fabric 11 is separated at the shoulders.

[0011] On the back body 5 side, insulating fabrics 15A and 15B, which have been made insulated by aluminum vapor deposition, are lined between the outer fabric 11 and the lining 13, and their edges are sewn together with the edges of the outer fabric 11 and the lining 13 to form an integrated unit. These insulating fabrics 15A and 15B act as pocket fabrics to form an insulating pocket 17, which prevents heat from entering the inside of the insulating pocket 17 from the outside and prevents heat from escaping from the inside to the outside. The outer fabric 11 and the insulating fabric 15A are cut out in a superposed state, and a line fastener 19 is attached to the cut edge, and the insulating pocket 17 is opened and closed by this line fastener 19. Inside the heat insulating pocket 17, a net fabric is sewn to provide patch pockets 21, 21. The patch pocket 21 is sewn on both the left and right sides and the bottom, and is open on the top.

[0012] As described above, the outer fabric 11 is separated at the shoulders. The separated edge on the back body 5 side is sewn together with the edge of the shoulders of the heat insulating fabric 15A, and the gap between the heat insulating fabric 15A and the outer fabric 11 on the back body 5 side is closed. The separated edges of the front bodies 7 and 9 are sewn together with the edges of the insulating fabric 15B to form a single plane. This stitching connects the gap between the lining 13 on the back body 5 side and the insulating fabric 15B to the gap between the outer fabric 11 and the lining 13 on the front bodies 7 and 9 side, creating a large gap 23. These stitches create an opening at the shoulder between the (outer fabric 11 + insulating fabric 15A) side and the (insulating fabric 15B + lining 13) side, and this area forms a small opening 17a of the insulating pocket 17.

[0013] At the bottom of the left front body 7, pocket fabric 25 is interposed between the outer fabric 11 and the lining 13, and the edge is sewn to the outer fabric 11 to form an inner pocket 27. Then, the outer fabric 11 is cut out, and a zipper 29 is attached to the cut edge, so that the inner pocket 27 can be opened and closed by the zipper 29. An external pocket 31 is provided below the inner pocket 27. The external pocket 31 opens below the fastener 29. Both ends of the stretchable tape are sewn to the left front body 7, and an insertion-type guide portion 32 is provided. The same structure is used on the right front side 9.

[0014] The underarm area between the left front body 7 and the back body 5 is connected in an adjustable manner using a belt 33 and a movable ring 35. The underarm area between the right front body 9 and the back body 5 is connected in a similar manner. The left front body 7 and the right front body 9 are also detachably connected using a belt 33 and a buckle 37 (female buckle 37a, male buckle 37b).

[0015] 5 and 6, at the back body 5 side, the edges of the overlapping cushion sheet 39 and sponge sheet 41 are sewn to the insulating fabric 15B to form an integrated unit. At the left front body 7 side, the edges of the cushion sheet 43 are sewn to the pocket fabric 25 of the inner pocket 27 to form an integrated unit. A square electric heating sheet 45 is placed in the gap 23 thus formed. Rectangular electric heating sheets 45A, 45B, 45C are placed on the body parts 5, 7, 9, respectively, taking their sizes into consideration. The base fabric 47 of the electric heating sheet 45 is a flat rectangular shape, and an electric heating wire made of a bundle of carbon fibers is embedded in the base fabric 47 in a serpentine state. For the electric heating sheet 45A, the edges of the base fabric 47 are sewn to a black protective sheet 49. The protective sheet 49 has an edge contour similar to that of the back body 5 .

[0016] On the back body 5 side, the edge of this protective sheet 49 is also sewn to the insulating fabric 15B to form an integrated unit. That is, the edges of the outer fabric 11, insulating pocket 17, cushion sheet 39, and sponge sheet 41, protective sheet 49, and lining 13 are sewn together to form an integrated unit. On the left front body 7 side, the outer fabric 11, pocket fabric 25, cushion sheet 43, electric heating sheet 45B and lining 13 are sewn together at their respective edges to form a single unit. On the right front body 9 side, the outer fabric 11, pocket fabric 25, electric heating sheet 45C, and lining 13 are sewn together at their respective edges to form a single unit.

[0017] The electric heating sheets 45A, 45B, 45C arranged on the body parts 5, 7, 9, respectively, are electrically connected to each other via a plurality of relay cords 51, with the electric heating sheets 45B to 45A to 45C. The tip of power supply cord 53 connected to electric heating sheet 45B is a USB terminal 55. A power button 57 attached to pocket fabric 25 of inner pocket 27 is inserted into power supply cord 53. Power button 57 is a push-button type, with the push surface located inside inner pocket 27. An insertion hole 25a is formed in pocket fabric 25, and the USB terminal 55 side is pulled out into inner pocket 27 through this insertion hole 25a. If a battery (not shown) is connected to this USB terminal 55, a power supply circuit is created, and when the power supply is turned on by pressing the power button 57, power is supplied to the electric heating sheet 45, which generates heat.

[0018] A cooling liner 59 is detachably attached to the lining 13 of the vest body 3. The cooling liner 59 has almost the same shape as the lining 13, and is divided into cooling liners 59A, 59B, and 59C for each section, which are adapted to the contours of the back body 5, the left and right front body sections 7 and 9, and the shoulder sections. As shown in Figure 3, the cooling liner 59 is made by joining a flat film 61 and a textured film 63, both of which are made of flexible plastic films made of synthetic resin such as polyethylene, in an overlapping state, and a phase change material 67 is enclosed in a sealed box-shaped container 65 formed between the textured film 63 and the flat film 61. This phase change material 67 is a so-called PCM (Phase Change Material) that changes from a solid phase to a liquid phase upon absorbing heat. In the present invention, this phase change material 67 is used as a cooling medium that cools the body by absorbing heat from the body side as latent heat of fusion. The solidification temperature of the phase change material 67 is adjusted to about 26°C so that it quickly returns from a molten state to a solidified state, for example, in about 10 minutes, when placed in a cooler box 79 or an insulated bag containing ice packs.

[0019] The phase change material 67 contains, for example, paraffin or aliphatic hydrocarbon (or fatty saturated hydrocarbon). The phase change material 67 contains, for example, tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ), and octadecane (C 18 H 38 The phase change material 67 contains at least one of tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ), and octadecane (C18 H 38 ) may be included.

[0020] The concave portion 59a is a two-layer sheet in which the flat film 61 and the concave / convex film 63 are joined, and can be folded at this portion. The flat film 61 side is aligned with the lining 13. The storage compartments 65 are arranged to match the uneven shape of the body, allowing the raised storage compartments 65 to effectively contact the body and fit. Even at the shoulders, they curve in a U-shape to fit when the wearer's own weight is applied. Therefore, a wide area of ​​the top surface of each storage compartment 65, 65, ... is in contact with the body, allowing heat to be drawn to the phase change material 67. Furthermore, the recessed portions 59a are open at the edges, providing an air escape route. This air escape route prevents air from becoming trapped inside the cooling liner 59, which comes into contact with the body, when worn. In summer, the heat causes a lot of sweat, and as this sweat evaporates, the wearer becomes stuffy. However, allowing air to escape through this air escape route prevents stuffiness.

[0021] The hook surfaces 69b of a plurality of hook-and-loop fasteners 69 are attached by sewing at appropriate intervals to the edge of the cooling liner 59. Correspondingly, as shown in FIG. 4, a loop surface 69a is also attached to the edge of the mating surface of the lining 13. Therefore, the cooling liner 59 is attached to the vest body 3 by the hooks on the hook surface 69b being hooked onto the loops on the loop surface 69a.

[0022] The cooling and heating vest 1 is constructed in this manner, and when worn as a cooling vest, the solidified cooling liner 59 is attached. The cooling liner 59 is detachable, so if you prepare another cooling liner 59 for replacement and fold it up compactly and store it in a cooler box 79 or similar as shown in Figure 7, it can be quickly regenerated, thereby maintaining the cooling function of the cooling vest. Because it does not take up much space, it can also be placed in the gap of a large cooler box with a built-in battery along with juice or other beverages. There are also insulated containers for plastic bottles, but you can also store them in small containers like this one. In addition, because it is not bulky, it can be worn as an inner layer and over which the cooling clothing or protective jacket that utilizes the fan described in Patent Document 1 can be worn. It does not get in the way when wearing a harness for working at height. Furthermore, it can be worn with a regular backpack, and in this case, the cooling liner 59 is pressed tightly against the body due to the weight, which has the advantage of increasing the cooling effect on the back.

[0023] 1, a water supply bag (water bag) 73 of a hydration system 71 can be stored inside the insulated pocket 17, with its hose 75 pulled out through the small opening 17a, allowing for appropriate hydration. A belt 74 attached to the insulated pocket 17 side is threaded through a hole in the brim 73a of the water supply bag 73, and the belt 74 is closed in a ring shape, so that the water supply bag 73 is stored in an upright position inside the insulated pocket 17. The water supply bag 73 is closed with a stopper 73b, so that water can be added later by removing and opening the stopper 73b. Since the water is stored in the insulated pocket 17, if it is stored after being cooled, it will remain cool for a certain period of time. However, if, for example, a commercially available sheet-shaped ice pack 77 is placed in the patch pocket 21 as shown in FIG. 2, the water in the supply bag 73 will be actively cooled and will remain cool for a long period of time. Even if the hydration system 71 is not used, the backpack can be turned into an insulated backpack by placing ice packs 77 in the insulated pocket 17.

[0024] When worn as a cold weather vest, the cooling liner 59 is removed. Then, a portable battery is connected to the USB terminal on the heating sheet 45 side, and heat is generated by pressing the power button 57. The power can be adjusted to strong, medium or weak by pressing the power button 57 in different ways. It is not bulky, so you can wear it as an inner layer and then put on a cold weather jacket over it. It does not get in the way when wearing a harness for working at heights. Furthermore, it is possible to carry a normal backpack, in which case the weight of the bag will cause the electric heating sheet 45 to adhere closely to the body, which has the advantage of increasing the effect of keeping the back warm. Also, if you put a hot drink in the insulating pocket 17, it will stay warm.

[0025] The cooling and heating vest 1 has a large insulated pocket 17, so it can be used not only for cooling and protection from the cold, but also as a regular backpack. It can also be easily worn for commuting to work.

[0026] Although the embodiments of the present invention have been described in detail above, the specific configuration is not limited to these embodiments, and the invention also includes design changes within the scope of the present invention without departing from the gist of the present invention. For example, in this state, the arrangement pattern of the storage portions 65 of the cooling liner 59 can be changed as appropriate depending on the size of the vest body 3, etc. [Explanation of symbols]
