[0009] The present invention will be described below.Unless otherwise specified, it should be understood that the terms used in this specification are used in the sense that they are commonly used in the field.Therefore, unless otherwise defined, all technical terms and scientific and technical terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this invention belongs.In the case of conflict, this specification (including definitions) shall prevail.

[0010] In this specification, the term "about" refers to a range of ±10% of the subsequent number.

[0011] In this specification, a hole with a diameter of about X mm refers to a hole of any shape that fits within a square with one side of about X mm. The shape of the hole is not limited to a circle, but can be any shape such as an ellipse, octagon, hexagon, or rectangle.

[0012] FIG. 1 is a schematic diagram conceptually showing a body-worn cooling system 100 having a basic configuration according to the present invention.

[0013] The present invention aims to provide a body-wearable cooling system that is easy to wear on the body as a system for cooling the body by using heat of vaporization, The above problem has been solved by providing a body-worn cooling system 100 for cooling the body of a wearer with liquid L contained in a container 11, the body-worn cooling system 100 comprising: a first tube 110a extending from the container 11; a pump 12 for delivering liquid L from the container 11 to the first tube 110a; and an upper garment 13 having a first connecting member 120a configured to be worn on at least the upper body, the first connecting member 120a and the first tube 110a being configured to be connectable to each other, and the first connecting member 120a having at least one first hole 20a for releasing the liquid L.

[0014] Therefore, the body-worn cooling system 100 of the present invention includes a first tube 110a extending from a container 11 containing liquid L, a pump 12 for delivering the liquid L from the container 11 to the first tube 110a, and an upper garment 13 worn on the upper body, and the first connecting member 120a provided on the upper garment 13 and connectable to the first tube 110a has at least one first hole 20a for discharging the liquid L delivered from the container 11 to the first tube 110a by the pump 12. Other configurations (e.g., the structure, number, etc. of the tubes and connecting parts) are not particularly limited and may be arbitrary. These will be described in detail below.

[0015] (Tube structure) As long as the tube is a cylindrical member, the cross-sectional shape is not limited, and it may be circular, elliptical, or polygonal, such as rectangular, hexagonal, etc. The material is not limited as long as it is flexible, and may be made of resin or rubber, and a specific example is a vinyl tube (e.g., a soft polyurethane tube).

[0016] Here, the length of the first tube 110a may be about 100 cm to about 200 cm based on the size of a person's body (particularly the size of the upper body). For example, the length L of the first tube 110a is about 130 cm. If the first tube 110a is too long, it becomes a hindrance, and if it is too short, the manual pump 12 and the container 11 are too close to the body (top 13) and difficult to handle.

[0017] In one embodiment, the inner diameter of the first tube 110a is about 3 mm to about 5 mm, and specifically, for example, about 4 mm.

[0018] (Structure of connecting members) The structure of the connecting member is not limited as long as it has a hole for releasing liquid from the tube, and the material may be made of resin, rubber, or metal such as stainless steel.

[0019] The connecting member may be composed of one part fixed to the upper garment, or may be composed of multiple parts, at least one of which is fixed to the upper garment. When the connecting member is composed of multiple parts, the connecting member may include, for example, two parts, a fixing part fixed to the upper garment and a connecting part to which the tube is connected, and the fixing part and the connecting part may be configured to be connectable and separable.

[0020] When the connecting member is configured as one part, it is preferable that the connecting member and the tube are configured so as to be connectable by, for example, press-fitting one into the other. In this case, the tube is detachably attached to the upper garment by the connecting member.

[0021] Furthermore, when the connecting member includes two parts, a fixing part and a connecting part, as described above, the connecting part to which the tube is connected can be connected or disconnected from the fixing part fixed to the upper garment, so that the tube can be detachably attached to the upper garment while remaining connected to the connecting part of the connecting member, thereby simplifying the work of attaching the tube to the upper garment.

[0022] (Number of tubes and connecting parts) The number of tubes and the number of connecting members may be any number. For example, the number of tubes and the number of connecting members may be one each as in the body-worn cooling system 100 shown in FIG 1, or may be two each as in the body-worn cooling system 100a shown in FIG 2.

[0023] FIG. 2 is a schematic diagram conceptually illustrating a two-tube body-worn cooling system 100a of the present invention.

[0024] For example, in one embodiment, as shown in Fig. 2, a body-worn cooling system 100a further includes a second tube 110b in addition to the first tube 110a, and the upper garment 13 further includes a second connection member 120b having at least one second hole 20b for discharging the liquid L in addition to the first connection member 120a, and the second tube 110b is preferably configured to be connectable to the first connection member 120a and the second connection member 120b. In this case, the liquid L is discharged not only from the first hole 20a of the first connection member 120a but also from the second hole 20b of the second connection member 120b, so that the body is evenly wetted with the liquid.

[0025] Each of these tubes and connecting members may be provided in numbers of three or more, rather than two as in the body-worn cooling system 100a shown in FIG. 2, but at least one of each is sufficient as in the body-worn cooling system 100 shown in FIG. 1.

[0026] (Second tube 110b) Also, the second tube 110b may only differ from the first tube 110a in length, and the length of the second tube 110b is about 10 cm to about 50 cm. The second tube 110b may have an inner diameter different from that of the first tube 110a. For example, the second tube 110b may have an inner diameter larger than that of the first tube 110a.

[0027] (Arrangement of two connecting members in the top 13) When the first connecting member 120a and the second connecting member 120b are provided on the upper garment 13 as in the body-worn cooling system 100a, it is preferable that the first connecting member 120a is disposed at the rear neck portion of the upper garment 103, and the second connecting member 120b is disposed at the front neck portion of the upper garment 13 (see FIG. 8(a)). Here, the front neck portion is the portion of the front body (i.e., the portion anterior to the coronal plane of the human body), and the rear neck portion is the portion of the rear body (i.e., the portion posterior to the coronal plane of the human body). In this case, the cooling effect can be enhanced by ensuring that the front and rear of the upper body are wet.

[0028] Furthermore, with such an arrangement of the two connecting members, even if the wearer's physique (neck size and shoulder width) or posture varies slightly, the relative positional relationship between the front and rear of the top around the wearer's neck does not change, so the position of the first connecting member 120a can be maintained at the rear neck portion of the top, and the position of the second connecting member 120b can be maintained at the front neck portion of the top.

[0029] However, the positions of the first connecting member 120a and the second connecting member may be appropriately set depending on the application of the body-worn cooling system 100. Therefore, the first connecting member 120a and the second connecting member 120b may both be disposed at the front neck portion of the upper garment, or both may be disposed at the back neck portion of the upper garment (see FIG. 3).

[0030] (Diameter and number of holes in connecting members) When the second holes 20b are located farther from the pump 12 than the first holes 20a, it is preferable that the diameter of the second holes 20b is larger than the diameter of one of the first holes 20a (see FIG. 2). This is because, since the first holes 20a are located farther from the pump 102 than the second holes 20b, when the diameters of these holes are equal, the amount of liquid discharged due to a pressure drop of the liquid is smaller in the second holes 20b than in the first holes 20a. However, by making the diameter of the second holes 20b larger than the diameter of the first holes 20a, it is possible to suppress the amount of discharged fluid from the second holes 20b from decreasing compared to the first holes 20a.

[0031] Here, the diameter of each first hole 20a is about 0.5 mm to about 1.5 mm, more specifically about 1.0 mm, and the diameter of each second hole 2b is about 1.0 mm to about 2.0 mm, more specifically about 1.5 mm.

[0032] In addition, the number of the first holes 20a provided in the first connection member 120a and the number of the second holes 20b provided in the second connection member 120b are not limited, but in one embodiment, there is one first hole 20a and one second hole 20b (see FIG. 1). However, there may be two or more first holes 20a and two or more second holes 20b.

[0033] For example, as shown in Figures 8(b) and (c), the first connecting member 120a may be provided with one first hole 20a, and the second connecting member 320b may be provided with two second holes 31b, 32b.

[0034] (Top) The outer garment is not limited in its use and configuration and may be any.

[0035] For example, the top may be configured to be worn over underwear (innerwear), or may be configured to be worn as underwear, or the top may be configured to be worn between underwear (innerwear) and outerwear (middlewear).

[0036] The upper garment may be made from a mesh material, or may be constructed from a material other than a mesh material that is highly breathable.

[0037] (container) The body-worn cooling system preferably further comprises a container containing liquid, and the container is preferably a vacuum insulated container. By comprising a container containing liquid, the body-worn cooling system becomes suitable for portability, and by using a vacuum insulated container as the container, the cooled liquid can be kept at a low temperature for a long time in the container, and the ability to cool the wearer's body can be maintained at a high level for a long time. However, in order to meet requirements such as weight reduction, it is preferable to use a container made of plastic with a simple structure such as a PET bottle, rather than a vacuum insulated container made of metal, which tends to be heavy.

[0038] (pump) The pump may be a manual pump or an electric pump having a built-in drive unit such as a motor.

[0039] As described above, the body-worn cooling system of the present invention, as shown in FIG. 1, comprises a first tube 110a extending from a container 11 containing liquid, a pump 12 for delivering liquid L from the container 11 to the first tube 110a, and an upper garment 13 worn on the upper body, and a first connecting member 120a provided on the upper garment 13 and connectable to the first tube 110a has at least one first hole 20a for releasing the liquid delivered by the pump 12 from the container 101 to the first tube 110a. Other configurations are not particularly limited, and for example, the number of connecting members and tubes is arbitrary, but in the following embodiment, a case in which the number of connecting members and tubes is two will be described as an example.

[0040] In particular, in embodiment 1 (Figures 3 to 7), a body-worn cooling system is described that has two connecting members and two tubes, the two connecting members are positioned on either side of the neck on the back side of the upper garment, and each connecting member has one hole formed therein.

[0041] In addition, in Modification 1 of the first embodiment (FIG. 8(a)), one of the two connecting members is disposed at the rear neck portion of the upper garment, and the other is disposed at the front neck portion of the upper garment.

[0042] In addition, in Modification 2 of the first embodiment (FIGS. 8(b) and (c)), one of the two connection members has two holes (liquid discharge holes) formed therein.

[0043] Furthermore, in embodiment 2 (Figures 9 and 10), a body-worn cooling system is described in which the connecting member is composed of two parts (i.e., a first part and a second part) that can be connected and separated, the first part being a fixing part that is fixed to the upper garment, and the second part being a connecting part that connects the tube, so that by connecting and separating the first part and the second part of the connecting member, the body-worn cooling system can be attached and detached to the upper garment while the tube remains connected to the second part of the connecting member.

[0044] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0045] (Embodiment 1) FIG. 3 is a schematic diagram for explaining the body-mounted cooling system 101 according to the first embodiment of the present invention.

[0046] The body-worn cooling system 101 of this embodiment 1 is a system for cooling the body of the wearer by liquid L contained in a container 11, and is particularly intended for use while riding a motorcycle or participating in outdoor sports.

[0047] That is, this body-worn cooling system 101 includes a container 11 containing liquid L, a first tube 110a extending from the container 11, a second tube 110b extending from the first tube 110a, a pump 12 for delivering the liquid L from the container 11 to the first tube 110a and the second tube 110b, and an upper garment 13. Whether the pump 12 is a manual pump or an electric pump can be appropriately selected depending on the usage form of this body-worn cooling system 101 (such as cooling while riding a two-wheeled vehicle or cooling while playing sports).

[0048] The upper garment 13 is configured to be worn on at least the upper body and has a first connecting member 120a having one first hole 20a for releasing the liquid L, and a second connecting member 120b having one second hole 20b for releasing the liquid L.

[0049] Here, the first connection member 120a, the first tube 110a, and the second tube 110b are configured to be connectable to each other, and the second connection member 120b and the second tube 110b are configured to be connectable to each other.

[0050] Here, first tube 110a and second tube 110b are configured with a flexible tubular member and may be made of resin or rubber, and a specific example is a vinyl tube (for example, a soft polyurethane tube).

[0051] The length of the first tube 110a may be about 100 cm to about 200 cm based on the size of a person's body (particularly the size of the upper body). For example, the length L of the first tube 110a is about 130 cm. If the first tube 110a is too long, it becomes a hindrance, and if it is too short, the pump 12 and the container 11 are too close to the body (top 13) and difficult to handle. In one embodiment, the inner diameter of the first tube 110a is about 3 mm to about 5 mm, and specifically, for example, about 4 mm.

[0052] The second tube 110b may differ from the first tube 110a only in length, and the length of the second tube 110b is between about 10 cm and about 50 cm, for example, about 15 cm.

[0053] In the upper garment 13, the first and second two connecting members 120a, 120b are arranged so as to be located on both sides of the neck (i.e., on the right and left sides of the central vertical axis) on the back side of the upper garment 13. Specifically, the first and second two connecting members 120a, 120b are arranged at positions about 4 cm to about 8 cm apart from the central vertical axis on the back side of the neck, and more specifically, they are arranged at positions about 6 cm apart from the central vertical axis on the back side of the neck. The diameter of the second hole 20b of the second connecting member 120b, which is located farther from the pump 12 than the first connecting member 120a, is larger than the diameter of the first hole 20a of the first connecting member 120a. This is to suppress a decrease in the amount of liquid discharged from the second hole 20b compared to the first hole 20a due to a decrease in liquid pressure in the second connecting member 120b, which is located farther from the pump 12 than the first connecting member 120a. For example, the diameter of the first hole 20a of the first connection member 120a is about 0.5 mm to about 1.5 mm, more specifically about 1.0 mm, and the diameter of the second hole 20b of the second connection member 120b is about 1.0 mm to about 2.0 mm, more specifically about 1.5 mm.

[0054] Fixing pieces 13a, 13b for fixing the first tube 110a to the upper garment 13 are attached along the sides of the upper garment 13. The fixing pieces 13a, 13b are formed of tubular members here, and these fixing pieces are configured so that the first tube 110a is fixed to the upper garment 13 by inserting the first tube 110a into the tubular members.

[0055] The specific configurations of the two connecting members will be described below.

[0056] FIG. 4 is a detailed explanatory diagram of the body-worn cooling system 101 shown in FIG. 3, with FIG. 4(a) and FIG. 4(b) showing enlarged views of the R2 and R1 portions of FIG. 3, respectively, and FIG. 4(c) showing an even further enlarged view of the structure of the cross section taken along line C1-C1 of FIG. 4(b).

[0057] As shown in FIGS. 4(b) and 4(c), the first connecting member 120a has a member body 121a to which the first tube 110a and the second tube 110b are connected, and a body support portion 122a that supports the member body 121a.

[0058] For example, when the first connecting member 120a is made of soft resin or rubber, the member body 121a and the body support part 122a are molded integrally. Here, the member body 121a and the tubes 110a, 110b are connected by pushing one end of the tube into a small diameter part formed at the tip of the member body 121a. The body support part 122a is fixed to the upper garment 13. Specifically, the body support part 122a is fixed to the upper garment 13 by sewing with a first sewing thread 22a. However, the manner of fixing is not limited to this, and for example, the body support part 122a may be fixed to the upper garment 13 by adhesion with an adhesive.

[0059] As shown in FIG. 4(a), the second connection member 120b, like the first connection member 120a, has a member body 121b to which the second tube 110b is connected and a body support part 122b that supports the member body 121b, and the member body 121b and the body support part 122b are integrally molded. Here, the member body 121b and the second tube 110b are connected by pushing the other end of the tube 110b into a small diameter part formed at the tip of the member body 121b. In addition, the body support part 122b is fixed to the upper garment 13 by sewing with a second sewing thread 22b. However, the manner of fixing is not limited to this, and for example, the body support part 122b may be fixed to the upper garment 13 by adhesion with an adhesive.

[0060] Next, a procedure for a user to use the body-worn cooling system 101 having such a configuration will be described.

[0061] Fig. 5 is a diagram for explaining the operation of connecting the first and second tubes 110a, 110b to the first and second connection members 120a, 120b attached to the upper garment 13 of the body-worn cooling system 101 shown in Fig. 3, and Fig. 6 is a perspective view showing an enlarged view of the R4 part (Fig. 6(a)) and the R3 part (Fig. 6(b)) of Fig. 5. Fig. 7 is a diagram for explaining the usage form of the body-worn cooling system 100 shown in Fig. 3, showing the state in which the upper garment 13 of the body-worn cooling system 101 is worn on the underwear 14.

[0062] When a user utilizes a body-worn cooling system 101 configured in this manner, as shown in FIG. 5, a first tube 110a is connected to a first connecting member 120a fixed to the upper garment 13, and this first connecting member 120a and a second connecting member 120b fixed to the upper garment 13 are connected by a second tube 110b.

[0063] Specifically, as shown in FIG. 6(b), one end of the first tube 110a is pressed against one end of the component body 121a of the first connecting member 120a, so that the small diameter portion at one end of the component body 121a is fitted into one end of the first tube 110a, and further, as shown in FIG. 6(b), one end of the second tube 110b is pressed against the other end of the component body 121a of the first connecting member 120a, so that the small diameter portion at the other end of the component body 121a is fitted into one end of the second tube 110b.

[0064] Furthermore, as shown in FIG. 6(a), the other end of the second tube 110b is pressed against one end of the second connecting member 120b, and the small diameter portion on the one end side of the second connecting member 120b is fitted into the other end of the second tube 110b.

[0065] This allows the liquid L delivered to the first tube 110a to pass through the first tube 110a to reach the first connecting member 120a, and then through the second tube 110b to reach the second connecting member 120b.

[0066] 7, the user puts on the top 13 of the body-worn cooling system 101 over the underwear 14, and connects the tip (other end) of the first tube 110a to the outlet of the pump 12 attached to the container 11. In this state, for example, by riding a two-wheeled vehicle, the user can cool his / her body with this system while riding, or by playing outdoor sports, the user can cool his / her body with this system while playing the sport.

[0067] Specifically, when the user operates the pump 12 to pump the liquid L in the container 11 to the first tube 110a while wearing the upper garment 13 as shown in FIG. 7 (see FIG. 7), the liquid L reaches the first connecting member 120a through the first tube 110a and is discharged from the first hole 20a (see FIG. 2). In the first connecting member 120a, before or at the same time as the liquid L is discharged from the first hole 20a, the liquid L is further sent to the second tube 110b through the first connecting member 120a and flows into the second connecting member 120b. As a result, in the second connecting member 120b, the liquid L that has flowed in is discharged from the second hole 20b (see FIG. 2). In this case, the first connecting member 120a and the second connecting member 120b are located on both sides of the neck on the back side of the user, so that the liquid L seeps into the underwear 14 on both sides of the back side of the neck.

[0068] The liquid L soaked into the underwear 14 in this way evaporates on the surface of the body, and the heat of vaporization at that time cools the user's body. At this time, since the upper garment 13 is made of a mesh material, the evaporation of the liquid L is not impeded.

[0069] Furthermore, with such a body-worn cooling system 101, after use, the top can be washed alone with the first tube 110a and the second tube 110b detached from the top 13, thereby keeping the top 13 clean. Note that the first tube 110a and the second tube 110b can be easily detached by pulling out the small diameter portions at both ends of the first connecting member 120a from the first tube 110a and the second tube 110b, and pulling out the small diameter portion at one end of the second connecting member 120b from the second tube 110b.

[0070] As described above, in the body-worn cooling system 101 of the first embodiment, the upper garment 13 includes first and second connecting members 120a, 120b to which the first and second tubes 110a, 110b are connected, and holes 20a, 20b are formed in each connecting member 120a, 120b for discharging liquid from the connected tube, so that the liquid L contained in the container 11 can be delivered to the tubes 110a, 110b by the pump 12, whereby the liquid L can be discharged toward the body from the holes 20a, 20b of the connecting members 120a, 120b. This allows the body of a wearer wearing the upper garment 13 to be cooled by the heat of vaporization of the liquid L.

[0071] In addition, since the connecting members 120a, 120b capable of connecting the tubes 110a, 110b are attached to the top 13, the wearer can easily attach the tubes and the connecting members to the body by simply putting on the top 13 by connecting the tubes 110a, 110b to the connecting members 120a, 120b before putting on the top 13.

[0072] In addition, the upper garment 13 is provided with two connecting members 120a, 120b, and each connecting member 120a, 120b is provided with holes 20a, 20b for releasing the liquid from the tube, so that the liquid L delivered to the tube is released at two points on the upper garment 13, allowing the upper garment 13 to be more evenly wetted and the body to be more evenly cooled by the latent heat of vaporization.

[0073] Furthermore, since the diameter of the second hole 20b formed in the second connecting member 120b is larger than the diameter of the first hole 20a formed in the first connecting member 120a, it is possible to prevent the amount of liquid L released from the second hole 20b, which is located farther from the pump 12 than the first hole 20a, from decreasing compared to the amount released from the first hole 20a.

[0074] In the above embodiment 1, two connecting members 120a, 120b are arranged on either side of the neck on the back side of the jacket, and each connecting member 120a, 120b has one hole 20a, 20b formed therein. However, the number and arrangement of the connecting members, and further the number of holes for discharging liquid formed in one connecting member, are not limited.

[0075] Fig. 8 is a diagram for explaining modified examples of the body-worn cooling system 101 shown in Fig. 3, in which Fig. 8(a) shows the feature of Modification 1 (arrangement of the connection member), Fig. 8(b) shows the feature of Modification 2 (two second holes), and Fig. 8(c) is an enlarged view of the R5 portion of Fig. 8(b). Note that Fig. 8(a) and Fig. 8(b) show a portion corresponding to the R0 portion in the body-worn cooling system 101 shown in Fig. 3.

[0076] (Modification 1 of the first embodiment) For example, in the first modified example of the first embodiment (FIG. 8(a)), one of the first and second connecting members 120a and 120b, for example, the first connecting member 120a, is disposed at the rear neck portion of the top 13, and the other, for example, the second connecting member 120b, is disposed at the front neck portion of the top. Specifically, the first connecting member 120a is disposed at the center of the rear neck portion of the top 13, and the second connecting member 120b is disposed at the center of the front neck portion of the top. More precisely, the first connecting member 120a and the second connecting member 120b are located on the approximate median plane of the wearer wearing the top 13. Here, the approximate median plane refers to a position that is shifted from the median plane to the left or right within about 1 cm.

[0077] This arrangement enhances the cooling effect by ensuring that the front and back of the upper body are wet.

[0078] Furthermore, with such an arrangement of the two connecting members, even if the wearer's physique (neck circumference or shoulder width) varies slightly or if the wearer changes his / her body position, the relative positional relationship between the front and rear of the upper garment 13 does not change, so the position of the first connecting member 120a can be maintained at the rear neck portion of the upper garment, and the position of the second connecting member 120b can be maintained at the rear neck portion of the upper garment.

[0079] However, the positions of the first connecting member 120a and the second connecting member 120b may be appropriately set depending on the application of the body-worn cooling system. Therefore, both the first connecting member 120a and the second connecting member 120b may be disposed at the front neck portion of the upper garment.

[0080] (Modification 2 of the first embodiment) In the second modification of the first embodiment (FIGS. 8(b) and 8(c)), two holes (liquid discharge holes) are formed in one of the two connection members.

[0081] Specifically, in the body-worn cooling system shown in Fig. 8(b), the first connecting member 120a close to the pump 12 has one first hole 20a formed in the connecting portion 121a as in the first embodiment, while the second connecting member 320b far from the pump 12 has two holes 31b, 32b formed as second holes in the member body 321b to which the second tube 110b is connected. Here, the diameters of the two second holes 31b, 32b are the same, but one diameter may be larger than the other. In other words, the diameter of the second hole 31b may be larger or smaller than the diameter of the second hole 32b.

[0082] In this way, in the second connecting member 320b, which is farther from the pump 12 than the first connecting member 120a, by providing two second holes 31b, 32b as holes for discharging the liquid L, it is possible to suppress a decrease in the discharge amount due to a decrease in liquid pressure.

[0083] This is because the second connecting member 320b is located farther from the pump 12 than the first connecting member 120a, and therefore the amount of liquid discharged due to a pressure drop in the discharged liquid is smaller in the second connecting member 320b than in the first connecting member 120a. However, by providing two holes in the second connecting member 320b for discharging the liquid L, it is possible to prevent the amount of discharged fluid from decreasing in the second connecting member 320b compared to the first connecting member 120a due to a pressure drop in the liquid L.

[0084] In the second modification, the positions of the first connecting member 120a and the second connecting member 120b may be appropriately set according to the application of the body-worn cooling system. Thus, the first connecting member 120a may be disposed at the rear neck portion of the upper garment, and the second connecting member 320b may be disposed at the front neck portion of the upper garment.

[0085] In addition, in the first embodiment, the first connecting member 120a and the second connecting member 120b are fixed to the upper garment 13, and when an operator uses the body-worn cooling system 101, the operator needs to push the tube into the member body of the connecting member fixed to the upper garment 13 to attach it, but by configuring the connecting member to include two parts, a first part (a fixing part fixed to the upper garment 13) and a second part (a connecting part to which the tube is connected) and configuring these parts to be connectable and detachable with a single touch, the operation of pushing the tube into the connecting member to attach it can be simplified. Hereinafter, a body-worn cooling system configured in this way will be described as the second embodiment.

[0086] (Embodiment 2) FIG. 9 is a plan view for explaining a body-worn cooling system according to embodiment 2 of the present invention, in which FIG. 9(a) shows a portion corresponding to portion R0 of upper garment 13 shown in FIG. 3, FIG. 9(b) and FIG. 9(c) show enlarged views of portions R7 and R6 in FIG. 9, and FIG. 9(d) shows the structure of a cross section taken along line C2-C2 in FIG. 9(c).

[0087] The body-worn cooling system of embodiment 2 is configured such that, instead of the first connecting member 120a and the second connecting member 120b each consisting of one component in the body-worn cooling system 101 of embodiment 1, a first connecting member 400a and a second connecting member 400b each consisting of two components are provided, and the other configurations are the same as those in the body-worn cooling system 101 of embodiment 1.

[0088] Therefore, the following mainly describes the structures of the first connecting member 400a and the second connecting member 400b.

[0089] In the body-worn cooling system of embodiment 2, as shown in FIG. 9(a), similar to the body-worn cooling system 101 of embodiment 1, the upper garment 13 has a first connecting member 400a connected to the first tube 110a and the second tube 110b, and a second connecting member 400b connected to the second tube 110b.

[0090] However, in this embodiment 2, the first connecting member 400a includes two parts: a first part (fixing part) 410a fixed to the upper garment 13 and a second part (connecting part) 420a to which the tubes 110a, 110b are connected, and these parts are configured to be connectable and separable.

[0091] 9(c) and (d), the fixing part 410a has a fixing part main body 411a fixed to the upper garment 13 and an engagement protrusion 412a formed on the surface of the fixing part main body 411a. Also, the connecting part 420a has a connecting part main body 421a to which the first tube 110a and the second tube 110b are connected and a main body support part 422a that supports the connecting part main body 421a, and a first hole 40a that discharges the liquid L is formed in the connecting part main body 421a, and an engagement hole 423a that engages with the engagement protrusion 412a of the fixing part 410a by elastic deformation is formed in the main body support part 422a.

[0092] Like the first connecting member 400a, the second connecting member 400b also includes two parts: a third part (fixing part) 410b fixed to the upper garment 13 and a fourth part (connecting part) 420b to which the second tube 110b is connected, and these parts are configured to be connectable and separable.

[0093] 9(b), the fixing part 410b has a fixing part main body 411b fixed to the upper garment 13 and an engagement protrusion 412b formed on the surface of the fixing part main body 411b. The connecting part 420b has a connecting part main body 421b to which the second tube 110b is connected and a main body support part 422b supporting the connecting part main body 421b, the connecting part main body 421b is formed with a second hole 40b for discharging the liquid L, and the main body support part 422b is formed with an engagement hole 423b with which the engagement protrusion 412b of the fixing part 410b engages by elastic deformation. Here, the second hole 40b has a diameter larger than the diameter of the first hole 40a.

[0094] Next, a method of using the first connecting member 400a and the second connecting member 400b in the body-mounted cooling system of the second embodiment will be described.

[0095] FIG. 10 is a perspective view showing how to attach the tube of the body-worn cooling system of embodiment 2 to an upper garment, and FIG. 10(a) and FIG. 10(b) show how to use the second connecting member 400b and the first connecting member 400a, respectively.

[0096] In the first connecting member 400a, when the fixing part 410a and the connecting part 420a are connected to each other, as shown in FIG. 10(b), the engaging protrusions 412a of the fixing part 410a are elastically deformed and pushed into the engaging holes 423a of the connecting part 420a, thereby allowing the two to be joined with a single touch.

[0097] Similarly, in the second connecting member 400b, when the fixing part 410b and the connecting part 420b are to be connected, as shown in FIG. 10(a), the engaging protrusions 412b of the fixing part 410b are elastically deformed and pushed into the engaging holes 423b of the connecting part 420b, thereby allowing them to be joined with a single touch.

[0098] Therefore, in the body-worn cooling system of embodiment 2, the task of attaching the tubes 110a, 110b to the upper garment 13 can be easily performed by connecting the first tube 110a and the second tube 110b to the connection part 420a of the first connection member 400a, and connecting the second tube 110b to the connection part 420b of the second connection member 400b, and then connecting the fixing parts 410a, 410b of the first and second connection members 400a, 400b to the connection parts 420a, 420b with a single touch.

[0099] Furthermore, in the body-worn cooling system of the second embodiment, there is no need to frequently insert and remove the tubes 110a and 110b, and the tube tips can be prevented from becoming loose. This can reduce the possibility of water leakage between the tubes and the connecting members. Also, there is no need to insert and remove the tubes every time you wash the clothes.

[0100] Furthermore, in the first connecting member 400a of the body-worn cooling system of embodiment 2, the fixing part 410a fixed to the upper garment 13 and the connecting part 420a connected to the tubes 110a, 110b are separable, and further, in the second connecting member 400b, the fixing part 410b fixed to the upper garment 13 and the connecting part 420b connected to the tubes 110b are separable. Therefore, the upper garment 13 can be washed with the connecting members 420a, 420b with the holes 40a, 40b opened removed from the upper garment 13 together with the tubes, and the holes 40a, 40b of the connecting members 420a, 420b can be prevented from becoming clogged with debris generated during washing.
