[0013] Representative embodiments of a water storage bag and a cooling garment including the same according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the illustrated embodiments. Furthermore, since the drawings are intended to conceptually explain the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding. Furthermore, in the following description, the same or equivalent parts will be designated by the same reference numerals, and duplicate explanations may be omitted.

[0014] In this embodiment, a vest is used as an example of cooling clothing, but the present invention is not limited to this and can cover clothing with sleeves, such as work clothes and jackets.

[0015] 1. Composition of cooling clothing 1(A) and 1(B), the cooling garment 1 includes a front body 2, a back body 3, a water storage bag 4, a circulation path 5, and a pump 6. The cooling garment 1 may further include a power source (not shown) for the pump 6.

[0016] As shown in Fig. 2(A), the front body 2 is a fabric that covers the front side of a wearer U. Here, the front body 2 is divided into left and right parts 21 and 22 for ease of wearing, and these are detachably connected by fasteners 23 and 24, such as buckles. It is preferable that the fasteners 23 and 24 have lengths that can be adjusted as needed, for example, like adjustable belts. The front body 2 may also have pockets 25, 26 on the outer surface side.

[0017] As shown in FIG. 2(B), the back body portion 3 is a fabric that covers the back side of the wearer U. The back body portion 3 is connected to the front body portion 2 at the side portions 29 and shoulder portions 27, 28 (see FIGS. 1(A) and 1(B)). That is, the front body portion 2 and the back body portion 3 are integrally connected at the side portions 29. Furthermore, the front body portion 2 and the back body portion 3 are detachably connected at the shoulder portions 27, 28 by fasteners 27A, 28A such as hook-and-loop fasteners or buckles (adjustable belts). This increases the adhesion between the cooling garment 1 and the wearer U, improving cooling efficiency.

[0018] As shown in Figures 1(B) and 3, the water supply port 41 and cap 42 of the water storage bag 4 are provided on the outer surface of the back body 3, and these are covered with a cover 31. This prevents direct access to the cap 42 and inhibits unintentional opening of the cap 42.

[0019] The back body 3 also has a storage space 32 for storing the pump 6. The storage space 32 is accessible from the outside of the cooling garment 1 via a fastener 33. A hole 34 is formed in the storage space 32, and the pump 6 is connected to a water intake port 44 (see FIG. 9) of the water storage bag 4 via the hole 34. A holder (not shown) for holding the pump 6 may also be provided in the storage space 32.

[0020] The back body 3 is formed in a bag shape, and a water storage bag 4 is placed inside it (see FIG. 1(B)). The water storage bag 4 is a bag body that can store a cooling liquid such as water. The water storage bag 4 may extend into the front body 2. Details of the water storage bag 4 will be explained later.

[0021] As shown in FIG. 1(A), a circulation path 5 is provided on the inner surface of the front body 2 and the back body 3. The circulation path 5 is a flow path for cooling water that runs in a serpentine pattern on the inner surface of the front body 2 and the back body 3. In other words, the serpentine shape of the circulation path 5 increases the contact area with the wearer U. The circulation path 5 is, for example, a flexible resin hose, and is exposed on the inner surface of the front body 2 and the back body 3.

[0022] Here, the serpentine-shaped flow path is a circulation path in which the inlet and outlet of the water flow path are connected via folded portions. The angle of the folded portions may be approximately 180°, approximately right angles, or approximately acute angles (or approximately obtuse angles) depending on the shapes of the front body 2 and the back body 3. For example, in the back body 3, which has a large area and is approximately rectangular, it is preferable to provide folded portions at approximately 180° to increase the total area of ​​the water flow path. On the other hand, in the front body 2 having extensions such as the shoulders 27 and 28, it is preferable to set the folded portions at approximately right angles or approximately acute angles (or approximately obtuse angles) and extend them throughout the entire body.

[0023] More specifically, the circulation path 5 includes an outer circulation path 51 arranged along the edges of the front body 2 and the back body 3, and an inner circulation path 52 arranged within the area surrounded by the outer circulation path 51, and the outer circulation path 51 and the inner circulation path 52 are connected to form one circulation path 5. However, the outer circulation path 51 and the inner circulation path 52 may form separate circulation paths, or at least one of them may have a branch. The circulation path 5 can be fixed to the inner surface of the front body 2 and the back body 3 using, for example, a strip or tape, but is not limited to this.

[0024] The pump 6 supplies the water stored in the water storage bag 4 to the circulation path 5. As the pump 6, a tube pump, a diaphragm pump, or the like can be suitably used, but is not limited to these. The pump 6 is operated by a power source (not shown) such as a primary battery or a secondary battery. A portable battery is preferable as the power source, and is stored in the pockets 25, 26, for example.

[0025] The pump 6 is housed within the storage space 32 and is accessed via a fastener 33. The pump 6 may also be fixed within the storage space 32 to a holder (not shown).

[0026] 2. Water storage bag configuration The water storage bag 4 will now be described in detail. As shown in Figure 9, the water storage bag 4 has a bag-shaped main body 40. The main body 40 is made of a resin material such as urethane resin or vinyl chloride resin, and is watertight. The water storage bag 4 can store, for example, about 250 ml of water. The water storage bag 4 can also store a plate-shaped ice pack of an appropriate size.

[0027] A water inlet 41 is attached to the main body 40 for injecting water into the main body 40. When the water storage bag 4 is attached to the back body 3, the water inlet 41 may be exposed on the outer surface of the back body 3 (see FIG. 3). The water inlet 41 may also be located above the back body 3.

[0028] 9(C) and 10(A), the water supply port 41 is substantially cylindrical, and a groove may be formed on the inner circumferential surface for engaging with the cap 42. The inner diameter of the water supply port 41 may be, for example, about 6 to 9 cm.

[0029] 5 and 6, the water supply port 41 is detachably closed by a cap 42. That is, the water supply port 41 is opened and closed by the screw-type cap 42, thereby keeping the water storage bag 4 watertight.

[0030] The cap 42 may be cylindrical with a bottom, and may have a groove formed on its outer circumferential surface for engaging with the water supply port 41. The cap 42 may have a knob formed thereon to facilitate rotation of the cap 42 relative to the water supply port 41.

[0031] 10, an annular portion 43 is attached to the main body 40 or the water supply port 41. For example, the annular portion 43 may be attached at its outer edge to the end of the water supply port 41 on the main body 40 side.

[0032] In this embodiment, the annular portion 43 is an open sheet-like member. More specifically, the annular portion 43 is a resin sheet or a rubber sheet formed into an annular shape. Examples of materials for the annular portion 43 include, but are not limited to, plastics such as polyethylene, polypropylene, polyamide, polyurethane, and ABS; rubbers such as urethane, silicone rubber, natural rubber, styrene butadiene rubber, chloroprene rubber, acrylonitrile rubber, and urethane rubber; nonwoven fabrics; and polyester fibers.

[0033] The inner diameter of the annular portion 43 is smaller than the inner diameter of the water supply port 41 (see FIG. 1(B)). The inner diameter of the annular portion 43 may be, for example, 5 to 7 cm. Therefore, the annular portion 43 is exposed to the outside from the opened water supply port 41 (see FIG. 1(A)). Therefore, the annular portion 43 prevents cylindrical containers, such as PET bottles, from entering the main body 40 (see FIG. 8). For example, inserting a 500 ml PET bottle filled with frozen water into the main body 40 would allow the cooling garment 1 to function, but would tend to make it difficult for the user to put on and take off the cooling garment 1. Therefore, the annular portion 43 prevents the entry of objects that would hinder the ease of putting on and taking off the cooling garment 1. Therefore, a slim PET bottle may be acceptable. Alternatively, the annular portion 43 can be said to be a mechanism that prevents the contents of the main body 40 from accidentally spilling out of the main body 40.

[0034] The annular portion 43 may have a slit-shaped opening 43A formed along its inner edge (see, for example, FIG. 10(C)). That is, the slit-shaped opening 43A is formed between the outer edge and the inner edge of the annular portion 43. Water between the annular portion 43 and the water inlet 41 flows into the main body 40 through the slit-shaped opening 43A. Therefore, when water is being supplied, water that hits the annular portion 43 is prevented from leaking out of the water inlet 41, and accidental leakage of water from the water inlet 41 when the cap 42 is opened can be prevented.

[0035] 3. How to use cooling clothing How to use the cooling garment 1 will now be described. First, water is poured into the water storage bag 4. That is, the cooling suit 1 is placed on a desk or the like, and the cover 31 is opened to expose the cap 42 (see FIG. 3). The cap 42 is removed and the water supply port 41 is opened (see FIGS. 4 to 6).

[0036] Next, water W is poured into the water storage bag 4 from, for example, a plastic bottle or a hose (see FIG. 7). Additionally, for example, a plate-shaped ice pack can be put into the water storage bag 4 through the water supply port 41. The ice pack can cool the water, and the cooled water can be circulated, thereby enhancing the cooling effect on the wearer U.

[0037] However, a cylindrical container such as a plastic bottle will come into contact with the annular portion 43, and its insertion into the water storage bag 4 will be restricted (see FIG. 8). This prevents the water storage bag 4 from becoming too thick and breaking. Furthermore, since the annular portion 43 narrows the water supply port 41, the contents of the water storage bag 4 are prevented from spilling out.

[0038] Then, the water supply port 41 is closed with the cap 42, and the cap 42 and the water supply port 41 are covered with the cover 31. The wearer U puts on the cooling garment 1 (see FIG. 2) and adjusts the tightness using the fasteners 23, 24 and the fasteners 27A, 28A. That is, the cooling garment 1 is fastened to the body using the fasteners 23, 24 and the fasteners 27A, 28A so that the cooling garment 1 is fixed along the entire body. At this time, care is taken to ensure that the cooling garment 1 is not too tight. This allows the circulation path 5 to come into appropriate contact with the wearer U.

[0039] When a power source (not shown) is turned on, the pump 6 supplies the water in the water storage bag 4 to the circulation path 5, and the water circulates through the circulation path 5. At this time, the circulating water removes heat from the body of the wearer U, thereby cooling the body of the wearer U.

[0040] The water returning from the circulation path 5 to the water storage bag 4 is warmed by the heat from the wearer U, but is cooled by mixing with the water in the water storage bag 4 and circulates again through the circulation path 5. In this way, the body of the wearer U is repeatedly cooled.

[0041] Although one embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to these embodiments, and other improvements and modifications exist within the scope of the spirit and teachings of the claims. It will be readily apparent to those skilled in the art that all such improvements and modifications are included within the technical scope of the present invention. For example, the cooling garment may further include a heat transfer plate and an electronic cooling unit that cools the heat transfer plate. Such a cooling garment can more reliably cool the wearer's body by using two cooling means: cooling the heat transfer plate with the electronic cooling unit and circulating water in a water storage bag.
