Description

  The present invention relates to a cold-insulated garment that can be worn effectively when the body temperature rises significantly, such as during outdoor work in summer, to effectively prevent the body from rising.

Conventionally, as a garment that feels cold, a garment that uses a fabric that is excellent in heat dissipation at a portion corresponding to a chest or a back has been proposed in Patent Document 1.
Moreover, the fiber which feels cold when skin touches is proposed by patent document 2, and the garment formed with the cloth by such a fiber is considered to function as a garment which feels cold.
On the other hand, in work under high-temperature conditions, the cold insulation clothes of Patent Document 3 have been proposed as clothes to be worn in order to avoid dangers such as heat stroke that occurs when the temperature of the worker rises.

Japanese Patent Laid-Open No. 11-247011 Japanese Patent No. 5009798 JP 2011-001669 A

However, even if it is a garment that makes you feel cold as shown in Patent Document 1, for example, when it is formed in a protective clothing such as a top and bottom coverwear style worn in the midsummer hot weather, a large heat that rises during work It is very difficult to absorb energy. Moreover, even if it is a textile work clothes which feels cold like patent document 2, the body temperature which rises significantly at the time of the above work cannot be absorbed. Furthermore, since the cold insulation clothes of Patent Document 3 have a small cold insulation capacity, the work clothes worn under hot weather cannot sufficiently suppress the rise in the body temperature of the wearer.
Therefore, if the increase in body temperature cannot be effectively and continuously suppressed during work, for example, work efficiency under hot weather not only significantly decreases, but there is also a risk of causing heat stroke and the like.
Here, the cold storage capacity means the length of time until the cold storage material (including the frozen body) cooled to a low temperature (for example, near 0 ° C. or lower) returns to room temperature. To do.

  In view of the above problems, the present invention can effectively suppress an increase in body temperature that tends to rise rapidly just like wearing under the hot weather in midsummer. It is an object of the present invention to provide a cold garment that can be held.

  The composition of the presently designed cold clothes designed to solve the above-mentioned problems is to use at least a waterproof fabric for at least the outer material, or use the outer material and the lining material for the best shape, poncho shape, upper garment. A sheet-shaped or block-shaped cooling core material that has been cooled or frozen over substantially the entire area between the outer surface and the lining of the clothing shape. It is characterized by being housed.

  In this case, it is preferable that the garment-shaped body is formed by detachably inserting the core material. Examples of the insertion / removal part of the cooling core material formed on the garment include the hem part of the upper garment and the boundary part (armpit part) between the front body and the back body. In addition, a core material entrance may be provided in front of each body in a vertical direction or a horizontal direction by a line fastener. Moreover, in this invention, it can also be set as the form which forms in a plurality of divisions between the outer material and the lining of the said clothing shape body, and accommodates a cooling core material in each division. Examples of the shape of the section include a horizontally long slit shape, a vertically long slit shape, and a grid shape. Multiple compartments are used to improve the adhesion of the cooling core surface to the wearer, and to separate the flow due to temperature rise of the cooling core into compartments so that the flow does not collect in one place. It is. In addition, when formed in a plurality of sections, the core material can be taken in and out freely for each section.

Furthermore, in the present invention, a pocket for accommodating a coolant or a cold insulation material is provided in the front body, the back body, or both bodies inside the garment-shaped body, and the core material retained in water and the coolant or cold insulation material in the pocket are provided. The temperature of the core material can be lowered by exchanging heat.
Further, in the present invention, a clothing shape body is formed into a vest shape clothing shape by, for example, only the outer material, and at least one piece on the chest or / and the upper back corresponding to the chest inside the clothing shape body. Alternatively, a pocket larger than that may be provided, and the cooling core material may be freely inserted into and removed from the pocket.

  In addition, in the present invention, for example, a clothing shape body in the form of a top-and-bottom tie is formed on the outer surface of the above-described clothing shape body using a flame-retardant or non-combustible, heat-insulating fabric, and the clothing shape body For example, there is a cold insulation garment in which a plurality of vertically long pockets are provided on the inner surface of the upper garment, and a rod-shaped cold insulation material is accommodated in each pocket as a cooling core.

  As an example of the cooling core material in the present invention, a foam having a foam diameter of 1 mm to 1 mm or less is absorbed and frozen or cooled, or a sol-like or gel-like coolant enclosed in a flexible container is cooled. A thing can be selected and used.

  The present invention wears this garment-shaped body by inserting a cooling core material into and out of the so-called housing part formed between the outer material and the lining of the garment-shaped body such as a vest and an upper garment. Even if the worker is engaged in work in a high-temperature environment such as a hot summer in the summer, the worker can work without raising the temperature in the clothes until the cooling core material returns to room temperature.

The front view for demonstrating the embodiment which applied this invention to the vest-like clothes. The expanded plane sectional view of the principal part for demonstrating another example of the usage aspect of the cooling core material in this invention clothes shape body.

Next, exemplary embodiments of the present invention will be described with reference to the drawings.
In the cold insulated garment Cw which is an example of the garment-shaped body of the present invention formed in the vest shape of FIG. 1, since it can be vest, as an example, the left and right front body parts 1, 2 formed into a front opening type by the line fastener 3 and The left and right armpits 4 and 5 formed in the vicinity of the left and right shoulders, the rear body 6 continuously formed on the outer ends of the left and right front bodies 1 and 2, and both the body 1, 2 and 6 A vest, which is an example of a garment-shaped body, is formed by including a neck portion 7 formed on the top of the garment. There is also a collarless type around the neck.

  In addition to the above-mentioned vests, the garment shape body to which the present invention can be applied is a poncho type, with sleeves and without sleeves. There are three-quarter sleeves. In addition, so-called coveralls in which the upper garment and pants are integrally formed are also applicable to the present invention.

  In this example, the garment Cw of the present invention shown in FIG. 1 is formed into a garment-shaped body by a surface material Os and a lining material Is as illustrated in the cross-sectional view of FIG. 2, and the surface material Os is at least waterproof or waterproof. It is desirable to form with the material provided with heat insulation. As an example of this material, there is a flexible sheet material made of a synthetic resin having a waterproof surface and an inside formed in a foam layer. The foam layer may be either an independent or continuous type of cell. Foaming is not necessary for lifting that only requires a waterproof outer surface Os.

  The lining Is is a thin, breathable woven or non-woven fabric as an example, in order to increase the heat exchange efficiency between the cooling core members 81 to 83 (described later) inserted between the outer lining Os and the body surface of the wearer. It is formed by the net ground.

  In the present invention, three cooling cores 81, 82, 83 are accommodated in this example between the outer material Os and the lining Is of the garment Cw in FIG. Further, core material inlet / outlet ports 11, 21, 61 are formed so as to be freely opened and closed by line fasteners not shown in the figure.

The cooling cores 81 to 83 used in the present invention are formed of a synthetic resin foam such as a flexible plate-like PVA (polyvinyl acetal) foam or a butane foam as an example. This foam preferably has a foam diameter of 1 mm or less in order to ensure water retention.
The core members 81 to 83 are formed to have inner shapes of the left and right front bodies 1 and 2 and the back body 6 formed by the outer material Os and the lining Is respectively, and the thickness is set to about 1 mm to 20 mm as an example. Use what you did.

  As described above, the core materials 81 to 83 formed of a flexible synthetic resin foam such as a PVA foam in a plate shape are each hydrated and then cooled in a freezer or the like (including freezing). In this cooled state, the core material is inserted into the body parts 1, 2, 6 from the core material outlets 11, 21, 61 formed at the hem of the vest-like garment Cw in FIG. It is used in the mode of working. The cooling core material may also be put inside the collar 7 around the neck of the garment Cw.

As an example, when the cooling core material 81-83 having a thickness of 1 mm is worn in the body 1, 2, 6 and wearing the vest-like garment Cw of the present invention, the work is actually performed outdoors. It took about 3 hours for the core materials 81 to 83 to return to substantially normal temperature (15 ° C. to 20 ° C.).

Therefore, in the present invention, if the thickness of each of the cooling cores 81 to 83 is increased to increase the cold storage capacity, the temperature in the clothes can be increased for 5 to 6 hours even if worn in outdoor work, and the body temperature can be increased. Since it can be kept in an effectively suppressed state, it is possible to effectively prevent illness such as heat stroke by preventing an increase in body temperature during work in hot summer, for example.
As the cooling cores 81 to 83 used in the present invention, in addition to the above-mentioned water-frozen and frozen or cooled foam, a sol-like or gel-like coolant cooled in a flexible sealed container is used as the cooling core. It can be used as a material.

  In the above example, the front bodies 1 and 2 and the back body 6 each have a form in which one cooling core member 81 to 83 is housed between the outer material Os and the lining Is. 2. A space sandwiched between the outer material Os and the lining Is of the back body 6 is formed in a plurality of core material accommodating portions as viewed from the back and the back, and a cooling core material is put in each of the compartments. Good. In this case, an inlet / outlet for the cooling core material is formed in each section. Moreover, the shape seen from the front of each division is arbitrary, such as a horizontally long rectangle, a vertically long rectangle, a square, and a rhombus.

Next, another example of the present invention cold insulation garment Cw illustrated in FIG.
The example of FIG. 2 is the same as the example of FIG. 1 in that the cooling cores 81 to 83 are accommodated between the outer material Os and the lining Is of the garment Cw of the present invention. However, in the example of FIG. By providing a plurality of pockets 9 on the outer surface of Is and accommodating the coolant 10 (or the cold insulation material 10) in each pocket 9, for example, the cores 81 to 83 that have returned to room temperature to a temperature close to room temperature, The coolant 10 in each pocket 9 serves to transmit cold temperature as a low temperature source.

The present invention can also be applied to various protective clothing such as fire-resistant clothing and heat-resistant protective clothing in which the outer surface Os of the clothing shape body is formed of a flame-retardant or non-flammable material.
That is, although not shown, a rod-shaped core material in which, for example, a plurality of vertically long pockets are provided on the back surface (or the inside of the lining Is) of the flame retardant or non-flammable outer material Os of the protective clothing and the pockets are frozen. By storing (equivalent to the above-described cooling cores 81 to 83 and the cooling material 10), for example, the protective clothing wearer is protected from external heat even under a flame or under an extremely high temperature. .

  Since the present invention is as described above, it can effectively and efficiently prevent the body temperature of the wearer from rising by applying it to clothing such as upper and lower work clothes worn in hot weather in summer. Therefore, it is extremely useful as a garment for body cooling.

Cw Inventive cold clothing 1, 2, left and right front body 3 fastener 4, 5 arm insertion opening 6 back body 7 neck part 81-83 cooling core material 9 pocket 10 cooling material Os outer surface Is lining

Cooling the core material 81 to 83 for use in the present invention is formed of a synthetic resin foam such as a flexible plate-like PVA (polyvinyl acetal) foam or c Le Thanh foam as an example. This foam preferably has a foam diameter of 1 mm or less in order to ensure water retention.
The core members 81 to 83 are formed to have inner shapes of the left and right front bodies 1 and 2 and the back body 6 formed by the outer material Os and the lining Is respectively, and the thickness is set to about 1 mm to 20 mm as an example. Use what you did.

Flexible synthetic resin foam plate shape and formed the core material, such as PVA foam as described above 81 to 83, the cooling (freezing put the entire respective freezer, etc. were allowed to free immersed in each In this cooled state, the core material is inserted into the body parts 1, 2, 6 from the core material outlets 11, 21, 61 formed at the hem of the vest-like garment Cw in FIG. It is used in the manner of wearing and working. The cooling core material may also be put inside the collar 7 around the neck of the garment Cw. Moreover, since the said core materials 81-83 are freely put in and out, if the water etc. which were taken out and impregnated from each body 1, 2, 6 were squeezed out when not in use, the said clothes Cw will become lighter. So it can be folded compactly.
Since the cooling core materials 81 to 83 are synthetic resin foams, they can be made lighter if they have the same volume as the liquid, and have a larger volume if they have the same weight as the liquid. Therefore, the core material to be frozen by impregnating the foam with a liquid can maintain a low temperature state for a long time even with a compact core material.
