Description

  The present invention relates to a cooling device for protective clothing that is worn under protective clothing such as bulletproof clothing or blade-proof clothing and cools the wearer's body.

  Protective clothing such as bulletproof clothing and blade-proof clothing (hereinafter simply referred to as protective clothing) is generally heavy and must be firmly attached to the body so as not to interfere with activities. For this reason, a mesh material is placed between the protective clothing and the body to ensure breathability.

JP 2007-333315 A

  However, as described above, protective clothing is strongly attached to the body due to its nature, and conventional protective clothing has poor ventilation, so sweat from the body covered with protective clothing cannot evaporate and is uncomfortable due to stuffiness. There was a feeling. In particular, when wearing the conventional protective clothing when the outside air temperature is high, fatigue was severe and even painful. For this reason, the conventional protective clothing has a problem that it cannot be worn for a long time.

  This invention is made | formed based on the said situation, and when it wears protective clothing, it aims at providing the cooling device for protective clothing which can cool the person's body effectively. It is.

  The present invention for achieving the above object is a cooling device for protective clothing that is worn under protective clothing and cools the wearer's body, and a spacer for ensuring an air flow passage through which air flows, An air-leakable top cloth provided to cover the surface of the spacer on the side that contacts the protective clothing, and an air-leakable and transparent surface provided to cover the surface of the spacer on the side that contacts the wearer's body. A flat mat having a damp cloth, an opening formed at one end of the mat, and a predetermined portion of a portion of the mat that is not covered with protective clothing when the wearer wears protective clothing And a power supply means for supplying power to the blower means.

  In the cooling device for protective clothing according to the present invention, when the wearer wears the protective clothing, the blowing device is attached to a predetermined portion of the portion of the mat that is not covered with the protective clothing. Without being obstructed, the outside air can be taken into the air flow passage or the air flowing through the air flow passage can be discharged to the outside. For this reason, when the outside air is circulated in the air flow passage by driving the air blowing means, the sweat that has come out of the body of the wearer wearing the protective clothing evaporates, and the air flow passage passes through the moisture-permeable lower cloth. Is taken out and discharged to the outside. The body of the wearer can be cooled by taking advantage of the fact that the heat of vaporization is taken away from the body of the wearer when the sweat evaporates.

  Moreover, since the protective clothing is very heavy in its nature, when the wearer wears the protective clothing on the protective clothing cooling device, the protective clothing cooling device comes into close contact with the body. As a result, the air flow passage secured by the spacer is located in the immediate vicinity of the skin of the body, and outside air constantly circulates in the vicinity of the skin of the body. Evaporates efficiently without staying in underwear. Therefore, the wearer can obtain a large cooling effect. In addition, when the temperature of outside air is lower than the temperature of the body surface, there is also an effect that the body is directly cooled by the outside air.

  In the protective clothing cooling apparatus according to the present invention, a length-adjustable hanging portion for hanging the mat from the neck or shoulder of the wearer may be attached to the upper portion of the mat. Thus, the wearer can easily wear the protective clothing cooling device using the hanging portion. Moreover, the wearer can easily adjust the vertical position of the mat according to his / her physique so that the blowing means is not covered with the protective clothing when the protective clothing is worn.

  Furthermore, in the cooling device for protective clothing of the present invention, attachment means for attaching the mat to the inner surface of the protective clothing may be provided at a predetermined portion of the upper cloth. As a result, the protective clothing cooling device and the protective clothing can be easily integrated, and the wearer can simply wear the protective clothing cooling device simply by wearing the protective clothing.

  According to the cooling apparatus for protective clothing of the present invention, when the protective clothing is worn, the person's body can be effectively cooled.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1A is a schematic front view of a protective clothing cooling device according to an embodiment of the present invention, and FIG. 1B is a schematic cross-sectional view of the protective clothing cooling device in the direction of arrows AA.

  The cooling device 10 for protective clothing of this embodiment is worn under protective clothing and cools the wearer's body. As shown in FIG. 1, a flat mat 11 and a fan (air blowing means) 21 are provided. And a power supply unit (power supply means) 22 and a neck strap (hanging unit) 23. The mat 11 includes a spacer 15, an upper cloth 16, a lower cloth 17, and a mesh cloth 18. The mat 11 is formed in a rectangular shape. Here, the horizontal width of the mat 11 is shorter than the vertical width.

  The spacer 15 is for securing an air flow passage through which air flows between the protective clothing and the wearer's body, and is formed in a rectangular shape. Moreover, since the spacer 15 is used for the protective clothing cooling device 10, the spacer 15 is required to have a special performance for its use. That is, first, when the protective clothing is worn on the protective clothing cooling device 10, the spacer 15 has a strength sufficient to withstand the weight of the protective clothing, and second, a fan with low power consumption is used. Sometimes, the spacer 15 has a structure having a small air resistance so that the outside air can be sufficiently circulated in the air flow passage by the fan, and thirdly, if the spacer 15 is too thick. When the protective clothing is worn on the cooling device 10 for protective clothing, the feeling of wearing becomes worse. On the other hand, if the spacer 15 is too thin, the air resistance increases, so the spacer 15 is about 0.5 centimeters. It has a thickness of about 1 centimeter. Examples of the spacer that satisfies all of these requirements include the spacers previously filed and patented by the present applicant, that is, the spacer disclosed in Japanese Patent No. 4067034. In this embodiment, the spacer disclosed in the above-mentioned Japanese Patent No. 4067034 is used as the spacer 15 used in the protective clothing cooling device 10. For this reason, the description about the detail of the spacer 15 is abbreviate | omitted here.

  The spacer 15 is covered with an upper cloth 16 and a lower cloth 17 except for its upper end. The upper cloth 16 is provided so as to cover the surface of the spacer 15 on the side in contact with the protective clothing. As the material of the upper cloth 16, a material that does not easily leak air to the outside is used. For example, a cloth made of plastic fibers such as a polyester cloth or a nylon cloth, or a high density cloth obtained by weaving yarns at a high density can be used. Further, a cotton cloth filled with eyes can also be used. On the other hand, the lower cloth 17 is provided so as to cover the surface of the spacer 15 on the side in contact with the wearer's body. As the material of the lower cloth 17, a material that hardly leaks air and has moisture permeability is used. For example, a high-density cloth or a clogged cotton cloth can be used. Further, the upper end portion of the spacer 15 is covered with a mesh cloth 18 having good air flow. The portion of the mat 11 provided with the mesh cloth 18 becomes an opening for taking out the air flowing in the air flow passage secured by the spacer 15 to the outside. The upper cloth 16, the lower cloth 17, and the mesh cloth 18 are stitched at each boundary portion, so that the spacer 15 is completely covered by the upper cloth 16, the lower cloth 17, and the mesh cloth 18.

  A circular hole is formed in the lower portion of the upper cloth 16. And the fan 21 is attached to this hole. The fan 21 forcibly generates an air flow in the air flow passage secured by the spacer 15. In the present embodiment, the fan 21 rotates in a direction to take outside air into the air flow passage. That is, the air intake method is adopted as the air blowing method of the fan 21. The air taken into the air flow passage by the fan 21 flows through the air flow passage and is discharged to the outside through the opening. Further, the mounting position of the fan 21 is a predetermined portion of the portion of the mat 11 that is not covered with the protective clothing when the wearer wears the protective clothing. This is because the fan 21 can take outside air into the air flow passage without being obstructed by the protective clothing.

  The power supply unit 22 is for supplying power to the fan 21. The power supply unit 22 includes a secondary battery, a battery case that houses the secondary battery, a variable resistor for adjusting a voltage supplied to the fan 21, and various switches. The power supply unit 22 and the fan 21 are connected by a cable. The various switches include a main switch for turning on / off the power supply to the fan 21 and an output adjustment switch for adjusting the value of the variable resistor. This power supply unit 22 is housed, for example, in a wearer's pants pocket.

  A string 23 for hanging the mat 11 from the neck of the wearer is attached to the top of the mat 11. The string 23 serves as a mounting means for mounting the protective clothing cooling device 10 on the body. Further, the string 23 is provided with a length adjusting mechanism 24 for adjusting the length thereof. Thereby, the wearer can easily adjust the vertical position of the mat 11 according to his / her physique.

Here, the orientation of the mat 11 is such that the lower cloth 17 is located on the side in contact with the body, that is, the fan 21 is located on the outside. Next, the wearer adjusts the length of the string 23 by the length adjusting mechanism 24 to determine the vertical position of the mat 11. Here, the vertical position of the mat 11 is set such that the fan 21 is not covered with the protective clothing when the protective clothing is worn later. Thus, as shown in FIG. 2, the wearer wears the protective clothing cooling device 10 so that the mat 11 is positioned on the chest and abdomen of the wearer. Thereafter, as shown in FIG. 3, the wearer wears the protective clothing 50 on the protective clothing cooling device 10. At this time, the fan 21 is not covered with the protective clothing 50. Moreover, the upper part of the protective clothing cooling device 10 covered with the protective clothing 50 is in close contact with the body of the wearer due to the weight of the protective clothing 50 and the wearing equipment of the protective clothing.

  Next, the wearer turns on the main switch of the power supply unit 22. As a result, the fan 21 is driven, and outside air is taken into the air flow passage through the fan 21. And the taken-in air distribute | circulates the inside of an airflow path upward, and will be discharged | emitted outside from the opening part, if an opening part is reached. By generating an air flow in the air flow passage in this way, sweat that has come out of the body of the wearer wearing the protective clothing evaporates and is taken into the air flow passage through the moisture-permeable lower cloth 17. And discharged to the outside. The body of the wearer can be cooled by taking advantage of the fact that the heat of vaporization is taken away from the body of the wearer when the sweat evaporates. In particular, in this embodiment, the cooling device 10 for protective clothing is in close contact with the wearer's body due to the weight of the protective clothing 50, so the air flow passage is located in the immediate vicinity of the skin of the wearer's body. For this reason, since the outside air constantly circulates in the vicinity of the skin of the body, the sweat discharged from the wearer's body can be efficiently evaporated without staying on the skin or underwear.
