DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling vest, and more particularly, to a cooling vest which is excellent in portability, has high flexibility, and efficiently cools a body.

[0002]

2. Description of the Related Art It is important for a person who performs sports or work in a high temperature environment to cool his / her body appropriately for efficient movement. Therefore, clothing for cooling to reduce body temperature is used. In particular,
In a high-temperature environment where electricity or the like is not connected, a method of lowering body temperature by directly applying a cold heat source such as a cold storage material to the body is adopted. However, according to this means, only partial cooling can be performed, and the effect is immediately lost, so that it cannot be said that this is an efficient cooling method. In order to solve such a problem, for example, a temperature control garment provided in Japanese Patent Application Laid-Open No. 6-257003 is provided.

The temperature control garment has a structure in which a large number of pockets are formed in a garment body, and the cooling source is removably housed in each pocket. In the pocket, the body surface side has a multilayer structure formed by superimposing clothing material, so that the temperature distribution from the cooling source to the body surface side can be set stepwise. Therefore, the body surface side is always maintained at the optimum cooling temperature, and the whole body can be efficiently cooled without being excessively cooled. When the cooling effect is reduced, the cooling effect can be maintained for a long time by replacing the cooling source of the pocket.

[0004] However, since the structure has a large number of heavy and hard heat sources in the pockets of the clothes, the weight of the whole clothes increases, and the degree of fatigue for the wearer increases. In addition, it lacks fit and the degree of freedom of movement of the body is greatly reduced, resulting in a poor feeling of wearing and bulky, which is extremely inconvenient to carry. Furthermore, since cooled water or cold storage material is used, it takes time to replace and cool, and lacks continuity.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing specific embodiments. First Embodiment FIGS. 1A and 1B show a cooling vest according to an embodiment of the present invention, wherein FIG. 1A is a front view and FIG. 1B is a rear view. Cooling vest A of the present invention
(Hereinafter, simply referred to as a vest) is a cooling pipe body P and a cooling gas (vaporized gas) connected to the cooling pipe body P.
And a cooling gas supply unit 5 for supplying the garment. And cooling vest A is
The outer material 11 and the lining 12 are formed doubly (in this example, the back body is formed as the doubly of the outer material 11 and the lining 12). The cooling pipe body P is disposed between the outer material 11 and the lining 12, and cools a necessary part of the body by passing cooling gas through a plurality of pipes 4 provided in the cooling pipe body P.

The cooling vest A has a clothing structure
The front body 2 includes a front body and a rear body. The front body 2 is divided at a central portion to form left and right front bodies (21, 22). The left and right front bodies 21 and 22 are, for example, buttons, fasteners, and the like. It can be opened and closed freely. A part of the back body 1 includes a cooling gas supply unit 5 for supplying a cooling gas to the cooling pipe body P.
Is stored. Therefore, in this example, a pocket 1A for accommodating the cooling gas supply unit 5 is formed in the rear body.

The lining 12 constituting the rear body is provided with an effective cooling effect of the cooling gas blown out of the pipe 4 in order to obtain an effective cooling effect.
Materials with relatively high air permeability are used. The lining 12 is preferably, for example, a cloth, particularly a knitted fabric or a netting, and is preferably made of natural fibers (cotton, silk, wool, etc.), artificial fibers (rayon, etc.), synthetic fibers (eg, polyester, polyamide, polypropylene) , Vinylon, aramid, etc.). If a knitted fabric or mesh is used for the lining 12 as described above, the cooling gas ejected from the mouth portion 41 of the pipe can be efficiently blown to the body from the mesh (stitch, cloth, mesh, etc.) of the lining.

On the other hand, the outer material 11 constituting the back body 1 is not made of a material having a higher air permeability than the lining so that the cooling gas is not excessively radiated to the outside. A material with a texture is preferred. In particular,
A fabric used as a surface material of clothing such as a knitted fabric or a woven fabric is preferable. By using such a fabric, it is possible to prevent the cooling gas accumulated in the vest from being excessively released to the outside without losing the sweating function. By the way, as described above, the back body 1 is provided with the pocket 1A capable of storing the cooling gas supply unit 5 described later.

The pocket 1A is provided with, for example, a slide fastener so that the cooling gas supply unit 5 stored in the pocket 1A can be reliably prevented from falling off.
As the position of the pocket 1A, at the appropriate position where the body does not feel as tight as possible when wearing it,
For example, it is more desirable to provide the vest A at the waist position.

By the way, the cooling pipe body P has a base 3 and
It comprises a pipe 4 projecting from its base 3. The base 3 of the cooling pipe P is provided with a cooling gas supply 5 as described later.
It has a structure that can be detachably attached to
It is a joint between the pipe 4 and the cooling gas supply unit 5. Therefore, different types of creasing vests can be manufactured by various combinations of the cooling gas supply unit 5 and the cooling pipe body P.

FIG. 2 is a view showing a part of a pipe in the cooling pipe body P. In this example, the pipe 4 is formed in a circular cross-sectional shape, and as the material thereof, a lightweight and flexible material such as a synthetic resin material or a synthetic fiber material having air permeability is used. The pipe 4 is as thin as possible. Specifically, for example, the outer diameter is about 6 mm or less and the thickness is 1 mm or less, preferably, the outer diameter is 3 mm, and the thickness is 0.5 mm. It is good to use the one of the degree.

In this embodiment, a plurality of pipes 4 having different lengths are arranged in the space between the outer material 11 and the lining 12 of the rear body so as to extend radially upward. Particularly, pipes having different lengths of pipes 4 are radially arranged in the central region of the back (see FIG. 1B). By radially arranging the pipes 4 having different lengths as described above, the cool air spouting from the openings 41 at the ends thereof is not biased to one place, but is dispersed throughout the central region of the back body 1. .
The back of the body is efficiently cooled by the dispersed cooling gas.

Since the pipe 4 has flexibility, it can be freely deformed, and is fixed to the backing 12 by welding, bonding, binding with a thread, or the like. For example, if the pipe 4 is a synthetic resin material, the one-point welding 8 (FIG. 3)
(A)) or by adhesion.
Further, if the pipe 4 is a synthetic fiber material, it is preferable that the pipe 4 be bound using an adhesive or a thread 9 or the like and appropriately fixed (see FIG. 3B).

As described above, the pipe 4 of the present invention does not hinder the flexibility of the vest itself from the viewpoint of the fixing method, the thickness, and the material. It can be freely followed and has extremely good wearability (wearability). Further, since the pipe 4 is indirectly attached via the lining 12, there is no low-temperature burn.

The gas passage of the pipe 4 in this example has only the opening at the tip. However, an opening is provided in the middle, and the opening at the tip and the opening at the middle are provided. Both may be provided. Further, the distal end may be closed and only have an opening partway. However, if a pipe made of a synthetic fiber material is used as the pipe 4 here, of course, a small amount of cooling gas is blown out of the pipe 4 because of a fine opening (a stitch, cloth, mesh, etc.) in the middle.

FIG. 4 shows another modification of the pipe. (A) is obtained by crushing the opening 41 of the circular pipe on the side from which the cool air is blown out to a small opening. By crushing the opening 41 in this manner, the cool air spouting from the opening 41 is diffused, and the cooling region is expanded.
In (B), the outer shape of the pipe 4 has a rectangular cross-sectional shape, the contact area where the pipe 4 is indirectly in contact with the skin is increased, and the body temperature can be more efficiently absorbed.

(C) and (D) are shown in FIG.
The pipe 4 is further provided with a number of small holes 42 corresponding to openings on the way. By causing a part of the cooling gas to be ejected from each of the small holes 42, a cooling effect is obtained in a region halfway to the tip of the pipe 4. Although the small holes 42 may be provided on all surfaces, preferably, the skin can be efficiently cooled by providing only the surface on the human body side. Such a pipe has an advantage that it is possible to prevent intensive blowing of the cooling gas from the opening 41 of each pipe. However, there is also a method of closing the opening 41 at the front end because a pressure loss occurs.

(E) is a pipe 4 made of synthetic fiber. This pipe 4 is made of synthetic fiber (for example, polyester,
It is composed of a hollow body (for example, a modulus hollow fiber body) made of polyamide or the like. Since the pipe 4 is provided with a large number of fine openings (a stitch, a cloth, a mesh, etc.), the same effect as the above (D) is obtained. In particular, in the case of this pipe 4, the wearability as a creeping vest is improved because of the flexibility and flexibility of the fiber material.

Next, the cooling gas supply section of the cooling vest will be described with reference to FIG. The cooling structure of the cooling vest is such that a cooling gas is generated from a cooling gas supply unit 5 and the cooling gas is passed through a pipe 4, a) only from the opening at the tip, b) or from the opening at the tip and an opening in the middle. ,
C) Or a structure in which it is ejected from the opening on the way to the body surface.

The cooling gas supply section 5 is roughly divided into a storage section 51 for storing the liquefied gas container 6, an air discharge section 52 for temporarily storing the cooling gas, and an outwardly extending side wall of the air discharge section 52. The gas passage 53 is formed. The liquefied gas container 6 is filled with a liquefied gas body that is a source of the cooling gas under pressure. As the liquefied gas, for example, a liquefied gas for cooling such as a nitrogen gas or a carbon dioxide gas is used, but a nitrogen gas is preferable in consideration of environmental problems. The storage unit 51 has a lid 5.
1A is attached.

Although an example in which two (a pair of) accommodating portions are provided will be described below, the present invention is not necessarily limited thereto, and one, three, or more may be used.
A nozzle 61 for discharging a liquefied gas is provided at the bottom of the liquefied gas container 6, and the liquefied gas in the container is discharged through the nozzle 61 when the nozzle 61 is pushed and retracted. The gas passage 53 is provided with a small hole 53A for inserting the nozzle 61 of the liquefied gas container. When the liquefied gas container 6 is stored in the storage portion 51 and the lid 51A is closed, the nozzle 61 of the liquefied gas container is pushed, and the liquefied gas in the container is ejected through the nozzle 61 (see arrow a).

By opening the lid 51A, the nozzle 61 of the liquefied gas container returns to the original state by the restoring force, and the supply of the liquefied gas can be stopped. The jetted liquefied gas is adiabatically expanded in the gas passage portion 53 and vaporized to become a cooling gas, and is temporarily stored in the gas discharge portion 52 (see arrow b).
The air discharge portion 52 is provided with a concave portion 52A for attaching the base 3 of the cooling pipe body described above.
Is set in the concave portion 52A, the air release portion 52 and the cooling pipe body communicate with each other.

Therefore, the cooling gas accumulated in the air discharge section 52 passes through the inside of the base, and is supplied to the clothing while spreading through the pipes 4 protruding and fixed to the base 3 (see arrow c). In this way, a cooling flow path is easily formed simply by setting the liquefied gas container 6 in the cooling gas supply unit 5, and the body can be easily cooled when necessary. As described above, since the cooling gas supply passage has a hollow simple structure, the weight of the vest itself is very light, it is convenient to carry, and the burden on the body when worn is greatly reduced.

In addition, since the liquefied gas container can be removed, the volume can be reduced accordingly when not in use. Further, the liquefied gas container 6 can be easily replaced with a new one, so that the cooling effect can be easily maintained. By the way, the number of pipes 4 provided on the cooling vest A is not particularly limited. The cooling gas supply unit 5 and the liquefied gas container 6 are made of synthetic resin, so that the weight of the cooling vest can be further reduced.
