Description

Article 30, Paragraph 2 of the Patent Act applies Published at JAPAN DIY HOMECENTER SHOW 2021 held from October 7 to 9, 2021

TECHNICAL FIELD The present invention relates to cooling clothing suitable for use in work sites or the like in hot environments.

Work in a high temperature environment such as in the summer tends to cause sweating and heat stroke. In order to prevent this, outside air is forced to form an airflow between the inner side of the clothes and the human body side by rotating the fan, and the perspiration is easily evaporated and cooled by the heat of vaporization generated at that time. Air-conditioning garments using the principle are known.
However, since there is a limit to the cooling effect of such an air-cooling system, in order to obtain a higher cooling effect, as described in Patent Document 1, a flow path is arranged in the garment body and a cooling liquid is circulated there. Liquid circulating cooling garments have been proposed for cooling by cooling.

In the vicinity of the lower side of this insertion hole 47, an extendable pump holder 51 is provided. Both lengthwise end portions of a short cut rubber tape are sewn to the outer surface side of the bag cloth 35a to form a single body. This pump holder 51 is also hidden by the bag cloth 35b of the pocket 35. As shown in FIG.

A plurality of extendable insertion type guide portions 53, 53, . . . The insertion-type guide portion 53 is formed by stitching both longitudinal ends of a fine rubber tape cut short to the inner surface thereof.

Inside the pocket 29, a flat-bag-like storage portion 55 made of a waterproof synthetic resin sheet is accommodated. A large circular hole is formed on one surface of the housing portion 55 , and this hole serves as the main opening of the housing portion 55 .
The bag cloth 29b of the pocket 29 is also formed with holes of the same size, the hole edges are aligned and overlapped, and the cap 57 is attached to the overlapped hole edges. Accordingly, the housing portion 55 is connected to the pocket 29 via the mouthpiece 57 . As shown in detail in FIG. 7, the lid 61 is connected to the mouthpiece 57 via a string 59. When the male threaded portion of the lid 61 is screwed into the female threaded portion of the mouthpiece 57, the housing portion 55 is opened. part is closed. A packing 63 is fitted in the lid body 61 to prevent the liquid from leaking.
The base 57, the cord 59 and the lid 61 are integrally molded of plastic. The cord 59 is thin and therefore flexible, but the base 57 and the lid 61 are rigid to some extent.

The clothing main body 3 side is configured as described above, and the cooling fluid circulation path 65 is incorporated. The cooling fluid circulation path 65 is composed of the housing portion 55 and a tube 67, and the tube 67 is made of plastic and is flexible. A tube 67 is connected to the housing portion 55 using the upper and lower sides of the housing portion 55 as connection portions, respectively, and when the lid 61 of the housing portion 55 is closed, the cooling fluid becomes a closed flow path.
The tube 67 is exposed on the inner surface of the garment body 3, which is made of mesh fabric, except for both ends. The exposed portions are successively inserted into the insertion-type guide portions 53, 53, . When the garment main body 3 is put on, the meandering portion 67a comes into contact with the wearer's jacket.

Both ends of the tube 67 are inserted into the pocket 29 through the insertion hole 39 .
One end of the tube 67 is directly connected to the upper connecting portion 55 a of the accommodating portion 55 housed inside the pocket 29 and communicates with the inside of the accommodating portion 55 . The other end is passed through the insertion hole 43 and pulled out into the inside of the pocket 35 in a U-shape. Inside the pocket 35, a pump 69 is held by the pump holder 51 and attached to the portion from which the pump 69 is pulled out. The other end of the tube 67 is located inside the pocket 29 and is connected to the lower connecting portion 55b of the accommodating portion 55 to communicate with the inside of the accommodating portion 55 .

As the pump 69 is operated, the cooling fluid flows as indicated by the arrow in FIG. 67 , flows through the meandering portion 67 a of the tube 67 , and then flows into the housing portion 55 again from the upper connecting portion 55 a of the housing portion 55 . In the cooling fluid circulation path 65, the cooling fluid circulates in such a flow.

A cord 69a of the pump 69 is passed through the insertion hole 47, enters the inside of the pocket 29, and is pulled out from a small opening 29c on the left side. Two upper and lower insertion guide portions 53, 53 are attached to the upper side of the insertion type guide portion 27 on the left front body 7. It passes through and is detachably connected to a controller 71 housed inside the pocket 25 .

The controller 71 has an external shape as shown in FIG. 6, and has an ON/OFF switch 71a on its outer surface. Power supply is stopped. The lamp 71b lights up while the power is being supplied. In addition, a USB connector 71c is provided for charging from the outside and supplying power to the outside. Since the controller 71 is housed in the pocket 25 of the left front body 7, it is easy to operate even when the cooling vest 1 is worn.
The controller 71 contains a battery and a microcomputer and is connected to the switch 71a and the motor of the pump 69. In cooperation with software, an operation mode execution function for controlling power supply to the motor is realized, and the pump 69 is operated. Operate.

In the operation mode execution function, a desired operation mode can be selected from a plurality of operation modes, and when the switch 71a is pressed, the operation mode is performed for 3 hours as measured by a timer. At that time, when the switch 71a is pressed once, the continuous operation mode is selected. When the switch 71a is pressed twice, the intermittent operation mode (1) of operation for 1 minute→stop for 1 minute→operate for 1 minute→stop for 1 minute→…… is selected. When the switch 71a is pressed three times, the intermittent operation mode (2) of operation for 20 seconds→stop for 1 minute and 30 seconds→operate for 20 seconds→stop for 1 minute and 30 seconds is selected. That is, the operation mode execution function includes an intermittent operation function for intermittently operating the pump 69 .
If the switch 71a is pressed long during operation, the operation ends.

As shown in FIG. 7, the lid 61 is removed from the base 57 of the container 55 so that the PET bottle P can be put in and taken out.
The inside of the accommodating portion 55 can accommodate a PET bottle P having a capacity of about 200 to 700 mL in a standing posture. It should be noted that the standing posture is not limited to being strictly upright, but includes the case of being leaned against the inner surface of the housing portion 55 and lying down. The PET bottle P is stored in a standing posture due to the lateral size of the storage portion 55 .

The cooling vest 1 has a cooling mechanism as described above, and when used, the lid 61 is opened, water W serving as a cooling fluid is introduced from the mouthpiece 57 , and the PET bottle P is accommodated in the accommodation section 55 .
The accommodating portion 55 is shaped like a flat bag, but is made of a flexible material made of synthetic resin, and when the PET bottle P is accommodated therein, it deforms and its intermediate portion swells. However, since the bottom is not flat, only a very small amount of water W can be added to bring the water level higher than the connecting portion 55b.

In this embodiment, the inside of the PET bottle P accommodated in the accommodation portion 55 is ice K in which the beverage is frozen. For example, it is assumed that a purchased and unopened container contains a beverage, or a container that has been emptied once, filled with water or the like, and frozen in a freezer.
When the cooling fluid circulation path 65 is formed by the operation of the pump 69 as described above, the water W flowing into the container 55 forms water droplets D, which hit the outer surface of the PET bottle P and slide down. In the process of falling, heat is taken and cooled, and it joins the lower puddle. The cooled puddle below is returned to the tube 67 side by the suction action of the pump 69 .

The water W only needs to be at a level that does not allow air to enter the cooling fluid circulation path 65, that is, the level of the water W contained in the housing portion 55 is higher than that of the lower connecting portion 55b. It is planned. Moreover, the durability of the cooling vest 1 can be improved by reducing the weight.
The ice K that freezes the beverage in the PET bottle P receives heat to cool the water W, so it gradually melts, but as shown in FIG. When the water W flows into the container 55 from the upper connection portion 55a, the water W forms water droplets D, and the water droplets D come into contact with the upper outer surface of the PET bottle P and slide down while dripping. Chilled. Therefore, the speed at which the ice K melts is slow. It should be noted that while the ice K is being melted, the ice K remains on the upper side of the PET bottle P until the end due to the relationship of specific gravity. When the water droplets D flow into the housing portion 55 from the upper connection portion 55a, they first contact the outer surface of the upper side of the PET bottle P and slide down from there. can be used without waste to cool the

It is also possible to intermittently operate the pump 69 as described above, and since the water droplets D do not flow into the container 55 when the pump 69 is stopped during the intermittent operation, the PET bottle P can be removed by intermittent operation. Ice K melts slower.
In this way, by contacting the water droplets D instead of immersing the PET bottle P in the water W and intermittently operating the PET bottle P, the life of the ice K of the PET bottle P is extended and the duration of the cooling effect is extended. Therefore, the replacement frequency of the PET bottle P can be suppressed.

On the other hand, the water W just cooled by the ice K is considerably cold, and since the tube 67 is exposed from the garment body 3, when the tube 67 through which the water W is circulated is touched, it is relatively strongly cooled. I feel However, when the water W that has just been cooled by the ice K is constantly circulating, the sense of coolness is dulled and the feeling of coldness is weakened.
In such a case, when the water W is warmed to a certain extent, it is cooled, and when the water W is warmed to a certain extent, it is cooled again. You will be able to feel
Therefore, if the optimum intermittent operation mode is selected, it also has the effect of providing comfortable coolness for a moderately long period of time. The above intermittent operation mode (2) has a relatively long stop period of 1 minute and 30 seconds, and when the coldness is exhausted to the point where it remains slightly cold, the coldness is instantaneously felt strongly again. It's becoming

Since the cooling vest 1 has a lightweight structure, it can be provided at a low cost and is not bulky. Therefore, when worn as shown in FIG. 9, it does not interfere with the movement of the wearer.
In addition, since the meandering portion 67a of the tube 67 is provided not only on the back body 5 but also on the front bodies 7 and 9, not only the back but also the chest can be cooled when worn. The garment main body 3 is configured flexibly, the cooling vest 1 is deformed along the shape of the wearer's body, and the tube 67 can also be moved to some extent while pulling the insertion-type guide portion 53, so that the meandering portion 67a can be applied to the back and chest. The cooling effect can be used without waste by contacting the
The cloth and tube 67 constituting the clothing body 3 of the cooling vest 1 are not special and can be obtained at a low cost, and sewing them to make the cooling vest 1 is a time-consuming task. It is also advantageous in terms of cost because it does not require special equipment or equipment.

When the ice K in the PET bottle P is melted, it can be taken out from the storage part 55 and replenished with water. The cooling vest 1 is lightweight and easy to put on and take off, and if it is hung on one shoulder all together, the pocket 29 can be brought to the front side, so that it can be handled like a bag containing a PET bottle P.
Frozen PET bottle drinks are also sold at convenience stores, so you can buy them and exchange them on the go.

The cooling vest 1 is provided with a plurality of pockets such as a pocket 21 convenient for storing portable small items, and is convenient as a multi-pocket type vest. At that time, if the cooling effect is not required, the PET bottle P may be taken out of the housing portion 5 and the housing portion 5 may be flattened.
Thus, the cooling vest 1 is user-friendly.

FIG. 10 shows a cooling vest 101 according to a second embodiment.
This cooling vest 101 has almost the same structure as the cooling vest 1, but has simple specifications that can be provided at a lower cost, and only the characteristic differences will be described.
In the cooling vest 1, one insertion type guide part 53 is made of one rubber tape, and the trajectory of the tube 67 is finely and optimally set, whereas this cooling vest 101 is a simple type. A plurality of insertion-type guide portions 103 are made by sewing one rubber tape not only on both ends but also on the middle.
The fabric is also thin, and the pocket corresponding to the pocket 35 for accommodating the pump 69 is also cut into a pocket shape, and the whole is flat.

FIG. 11 shows a cooling vest 105 according to a third embodiment.
Although this cooling vest 105 has almost the same structure as the cooling vest 1, it has a higher-grade specification with a longer duration of the cooling effect, and only the characteristic differences will be explained.
A heat insulating sheet 107 is sewn to the inner surface of each of the two bag cloths 29a and 29b forming the pocket 29 of the cooling vest 1. As shown in FIG. The heat insulating sheet 107 is formed by depositing aluminum on a base sheet of polyethylene, and is covered by sewing so that the aluminum surface is exposed.
By lining with the heat insulating sheet 107, the PET bottle P housed in the housing portion 55 can be kept cool. In addition, since it is possible to store a solid cooling agent in the gap of the pocket 29, if the cooling agent is accommodated there, the PET bottle P can be kept cold more strongly.
Therefore, by enclosing the PET bottle P to keep it cool, the ice K becomes more difficult to melt, so that the water W flowing through the exposed tube 67 can be cooled for a long time.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment. included.
Also, the manner and density of the tube 67 to be laid may be optimized according to the body size of the garment body.
