Description

This invention relates to cooling clothing that cools the wearer's body.

Traditionally, people who work outdoors or in factories or other hot and humid places in the summer often use cooling clothing to prevent heatstroke. There are cooling garments that use fans, but there are also cooling garments that circulate water or other fluids inside the garment to provide a refreshing feeling.

Patent document 1 describes a cooling garment in which a fluid such as water is stored in a storage section, a cooling medium is placed in a plastic bottle or the like and stored in the storage section, where the fluid is cooled to become a cooling fluid, and the cooling fluid is cooled by circulating through tubes that run throughout the entire garment.

In this cooling garment, the cooling fluid and cooling medium are poured into the opening of the valve-type storage section, and then the garment can be stored by closing the lid that is connected to the opening with a nozzle and string.

However, with this water-cooled suit, when the wearer is working while sitting on a chair, the lid of the storage compartment can interfere with the top of the chair, hindering the wearer's work. In addition, opening and closing the lid of the storage compartment of the water-cooled suit is troublesome, and there has been a demand for cooling clothing that allows for easier opening and closing.

Patent No. 7365739

In consideration of the above problems, the present invention aims to provide a water-cooled suit that is comfortable to wear when working while sitting on a chair or the like, and that can be opened and closed smoothly without the storage compartment on the back side getting in the way.

To solve the above problem, the cooling garment has a built-in circulation unit that circulates the cooling fluid contained in the storage section, and an insulating sheet is arranged between the storage section and an outer skin material, and the storage section has a storage opening, the insulating sheet has a sheet opening, and the outer skin material has an outer skin opening, and the storage opening, the sheet opening, and the outer skin opening are arranged at positions where they are connected, and an openable and closable zipper body is arranged in the storage opening.

The fastener body is preferably a waterproof fastener with resin laminated to the tape portion.

It is also preferable to have a cover that can close the opening in the outer shell.

In addition, it is preferable that the fastener body has an extension portion that extends from the slide portion and supports the grip portion, and that the extension support portion is located outward from the cover portion.

According to the invention described in claim 1, by arranging the storage opening, seat opening, and outer skin opening in a position where they communicate with each other, the area of the opening is smaller than that of the conventional valve-type opening and closing, and by opening and closing with a zipper, the parts on the back side are made smaller, and there is no discomfort such as the storage part hitting the top of a chair when working while sitting on a chair. This makes it possible to provide a water-cooled suit that opens and closes smoothly without the storage part on the back side getting in the way when working while sitting on a chair, etc.

According to the invention described in claim 2, the resin can be laminated to make the garment waterproof. This prevents the elements of the zipper from rusting and breaking, preventing the sliding part from sliding and causing the cooling fluid or cooling medium contained in the storage section to overflow from the outer shell, even if the zipper gets wet when the cooling fluid is stored in the storage section. The use of this waterproof zipper reduces the discomfort felt on the back side for the user, and allows the cooling garment to be used in the same way as a normal vest.

According to the invention described in claim 3, the opening of the outer shell is closed with the cover, so that the opening is not exposed to the outside, and a predetermined water-stopping effect can be achieved. In addition, it is possible to realize a cooling garment that has an excellent appearance similar to normal work clothes that do not have a valve-type storage section.

According to the invention described in claim 4, the fastener can be opened and closed easily even if there is a cover. Furthermore, because there is an extension on the fastener, the opening and closing can be easily performed even if the connecting positions of the storage opening, the sheet opening, and the outer skin opening are displaced due to use.

FIG. 2 is an overall front view of the cooling garment of the present embodiment. FIG. 2 is an overall rear view of the cooling garment of the present embodiment. FIG. 2 is a development view of the circulation unit of the present embodiment. 3 is an enlarged cross-sectional view of the BB portion of FIG. 2 taken along line AA.

The cooling garment of the present invention will be described with reference to the drawings. Note that the following description is of one embodiment and is not intended to limit the present invention.

As shown in Figs. 1 and 2, the cooling garment 1 is a vest-shaped garment made of synthetic resin such as polyester, which has excellent heat resistance, strength resistance, and transpiration properties, and has a circulation unit 2 inside that circulates a cooling fluid, a front body 3 at the front, a back body 4 at the back, and a belt (not shown) that connects the left and right front bodies 3 and 3 to the back body 4, a collar portion 5, and arm holes 6 through which the wearer puts his or her arms.

As shown in Figure 3, the circulation unit 2 is a unit that is inserted inside the cooling garment 1. In Figure 3, which shows the unfolded state, the front unit parts 11, 11 extending upward and to the left and right are placed inside the front body part 3, and the rear unit part 12 located below the center is placed inside the rear body part 4. The front unit parts 11, 11 and the rear unit part 12 are connected at the shoulders of the cooling garment 1.

The rear unit part 12 of the circulation unit 2 has a bag-shaped storage part 13 that can store cooling fluid, and the cooling fluid inside the unit can be circulated by a battery 21 and a pump 23. That is, the battery 21 is located in the front body pocket 7 on the lower right side of the front body 3 shown in Figure 1, and a switch 22 for switching the power on and off is located on the upper right side. The cooling fluid is received from the lower inside of the storage part 13 and circulated by the pump 23 in the rear body pocket 8 shown in Figure 2.

As shown in FIG. 3, the circulation unit 2 discharges cooling fluid from a nozzle 14a below the storage section 13 to the outside of the unit, and introduces the cooling fluid into the unit from a nozzle 14b above the storage section 13 via a tube (not shown) that passes through a pump 23. Above the unfolded storage section 13 shown in FIG. 3, there is a passage Z through which the cooling fluid can pass, and the cooling fluid is returned to the storage section 13 through the collar parts of the front unit section 11 and the rear unit section 12 and further through the front unit section 11.

The storage section 13 is bag-shaped and can store a medium that cools the cooling fluid. The cooling fluid can be cooled by storing ice packs, frozen plastic bottles, ice, etc. together with the cooling fluid.

As shown in FIG. 1, in the front body 3 which forms the front of the cooling garment 1, the circulation unit 2 (front unit parts 11, 11) is sewn and enclosed between the outer and inner skins which make up the front body 3.

The rear body 4, which forms the back of the cooling garment 1, has the circulation unit 2 (rear unit part 12) sewn inside the rear body 4, just like the front body 3. More specifically, as shown in FIG. 4, it is placed between the rear body outer skin 41, which is made of an outer skin material, and the rear body inner skin 42, which is closest to the user's back. Since it is bag-shaped, the storage part 13 is composed of the storage part inner skin 13a and the storage part outer skin 13b, and a cooling sheet 43 is placed between the storage part outer skin 13b and the rear body outer skin 41.

The opening will now be described. As shown in FIG. 2, the opening in this embodiment is located above the back body 4 and below the collar 5, and is a slit-shaped opening located at about one-fifth of the top to bottom length. This storage opening 13c can be opened and closed freely by a zipper body 50. The zipper body 50 is openable in the left-right direction, with the left-right direction being the longitudinal direction.

As shown in FIG. 4, the sheet opening 43a of the cooling sheet 43 and the outer skin opening 41a of the rear body outer skin 41 are arranged in the same position as the storage opening 13c (zipper body 50) of the storage section 13, so that the storage opening 13c can be exposed from the rear body outer skin 41. The outer skin opening 41a is also a slit-shaped opening, and auxiliary openings 41b, 41b are arranged on both the top and bottom sides of the outer skin opening 41a by sewing the base ends to make the opening portion easier to spread. A rectangular cover part 44 is arranged to cover and hide the outer skin opening 41a and auxiliary openings 41b, 41b of the rear body outer skin 41. The cover part 44 is sewn at the upper edge above the outer skin opening 41a and hangs down. Since the cover part 44 is located in a position where the storage opening 13c, the sheet opening 43a, and the outer skin opening 41a are connected, the storage opening 13c and the zipper body 50 are exposed when the cover part 44 is rolled up.

The fastener body 50 is formed by a pair of upper and lower tape sections, a pair of horizontally long tooth-like element sections at the opposing ends of the tape sections, and a slide section for opening and closing. The fastener body 50 is waterproofed by covering it with a resin such as polyurethane film through lamination.

The extension support part 60 has a string-like extension part attached to the slide part of the fastener body 50 through one end, and a roughly T-shaped grip part attached to the other end of the extension part. The user can move the storage opening 13c to open and close it by holding the grip part and pulling the extension support part 60. In addition, the grip part of the extension support part 60 is positioned outboard of the cover part 44. This not only allows the cover part 44 to stop water from entering the water, but also allows the storage opening 13c to be opened and closed easily even in cases where the storage opening 13c, sheet opening 43a, and outer skin opening 41a may become misaligned with use.

The method of using the cooling garment 1 will now be described. The cover portion 44 is rolled up, and the exposed storage opening 13c is opened using the fastener body 50. At this time, the opening of the storage opening 13c is widened, and the cooling fluid or medium is stored in the storage portion 13.

Next, by supplying power from the battery 21 and turning on the switch 22, the pump 23 causes the cooling fluid in the storage section 13 to flow through the tube 2a to the front body 3 and back body 4. This makes the cooling garment 1 at a comfortable temperature for the user. If the cooling fluid evaporates and decreases, for example, it is possible to replenish the cooling fluid in the storage section 13 or replace the medium using the fastener body 50 as appropriate.

This embodiment is as described above, but the present invention is not limited to the above. For example, the storage opening 13c is a horizontal slit, but it may be an upper or lower slit or a diagonal slit. Also, the storage opening 13c is located above the back body 4, but it may be located above and below, or it may be located only below.
