  The present invention provides a helmet-compatible air-conditioning garment for cooling a body by generating a flow of air substantially parallel to the surface of the body or underwear, and for sending air into the helmet when the helmet is worn to ventilate the helmet. The present invention relates to a clothing main body and a helmet compatible air-conditioning garment.

  2. Description of the Related Art In recent years, air conditioning clothing has been put to practical use in which a large amount of outside air is circulated substantially parallel to the surface of a body or underwear to evaporate sweat from the body. A detailed description of the principle and structure of the air-conditioning garment is described in detail in, for example, Patent Document 1. In addition, many people who wear air-conditioning clothing also wear a helmet, but in this case, wearing the air-conditioning clothing eliminates stuffiness of the body, but eliminates stuffiness of the head when wearing a helmet. It is not possible.

  In recent years, an apparatus for adding a ventilation function to an existing work helmet that meets safety standards has been put into practical use. Such a device is configured such that a blower is attached to an outer edge of a helmet, and outside air taken in by the blower is sent into the helmet by an introduction pipe.

JP-A-2005-54299

  However, the above-mentioned device for adding a blowing function to the work helmet has the following major performance problems. First, since the device is directly attached to the helmet, it is not possible to use a device having a fan that is too large in terms of weight. For this reason, a large amount of air cannot be sent into the helmet, and the stuffiness of the head cannot be sufficiently eliminated. Second, since the introduction pipe is provided in the gap between the helmet and the head, the cross-sectional area of the introduction pipe cannot be too large. Therefore, in order to sufficiently ventilate the inside of the helmet, it is necessary to increase the wind speed and send a large amount of air into the helmet. However, since the power consumption is proportional to the square of the wind speed, if the wind speed is increased, the battery is consumed immediately.

  The present invention has been made based on the above circumstances, and is not limited to stuffiness of the body, but can sufficiently eliminate stuffiness of the user's head when wearing a helmet. It is intended to provide air-conditioning clothing.

To achieve the above object, the present invention provides a garment section that covers at least the upper body of a user's body and includes a blast means attaching section for attaching a blast means for introducing air therein, and a user's neck. From behind, an ejection section for ejecting the air introduced by the blowing means, a guide sheet for guiding the air ejected from the ejection section upward, and an attachment means for attaching the guide sheet to a helmet, Wherein the guide sheet has one end fixed to a rear portion of the collar of the garment section, and the attachment means is provided at a tip end located at the other end of the guide sheet opposite to the one end , And the rear part of the helmet can be detachably connected.

  In the helmet-compatible air-conditioning garment body and the helmet-compatible air-conditioning garment according to the present invention, air is circulated inside the garment body using a blowing means, whereby the circulating air vaporizes perspiration from the body, and the sweat The user's body can be cooled by the heat of vaporization at the time of vaporization. In addition, by attaching the guide sheet to the helmet using the attaching means, when the helmet is worn, air spouting from the ejection portion can be guided to the helmet inside the guide sheet along the rear part and back of the user's neck. it can. For this reason, the sweat flowing out of the user's back and back of the neck can be vaporized by the air circulating inside the guide sheet, and the back and back of the neck can be cooled. And the inside of the helmet can be ventilated efficiently, so that the stuffiness of the user's head can be sufficiently eliminated.

  According to the helmet-compatible air-conditioning garment body and the helmet-compatible air-conditioning garment according to the present invention, when the helmet is worn, the air flowing through the inside of the guide sheet vaporizes the sweat that has come out from the back and back of the user's neck, The back of the neck and the back of the head can be cooled, and the air guided to the helmet can be efficiently introduced into the helmet and the inside of the helmet can be ventilated. can do.

  An embodiment for carrying out the invention according to the present application will be described below with reference to the drawings.

[First embodiment]
First, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a schematic rear view of a helmet-compatible air-conditioning garment according to a first embodiment of the present invention, FIG. 1B is a schematic side view of the helmet-compatible air-conditioning garment, and FIG. It is a general | schematic AA arrow direction outline partial cross section of clothes. FIG. 2 is a view for explaining the flow of air in the helmet-compatible air-conditioning garment, and FIG. 3 is a view for explaining a spout in the helmet-compatible air-conditioning garment.

  The helmet-compatible air-conditioning garment of the first embodiment can be used both when the helmet is worn and when it is not worn. As shown in FIG. 1, FIG. 2, and FIG. 3, the helmet-compatible air-conditioning garment 1 includes a garment unit 10, two air blowing units 20, 20, an air discharging unit 30, a power supply unit (not shown), and a power supply. It includes a cable (not shown), a jetting section 60, a guide sheet 70, and mounting means 80 for mounting the guide sheet 70 to the helmet 110. FIG. 1 shows a usage mode of the helmet-compatible air-conditioning garment 1 when the helmet 110 is worn, and FIGS. 2 and 3 show a usage mode of the helmet-compatible air-conditioning garment 1 when the helmet is not worn. It is shown.

  The clothing section 10 is a sheet-like material having small or no air permeability, and is formed in a shape that covers the upper body and the arms. An elastic member, such as rubber, is attached to the skirt 11 of the clothing portion 10. Thereby, the skirt 11 of the clothing part 10 is narrowed down and comes into close contact with the body or underwear. In addition, a zipper (not shown) as opening / closing means is provided on the front side of the clothing unit 10. The zipper is for opening and closing the front part of the garment unit 10 when the garment unit 10 is worn.

  The blowing means 20 forms an air flow passage between the clothing section 10 and the body or underwear by taking in air from the outside, and forcibly generates an air flow in the air flow passage. The two blowing means 20, 20 are attached to the lower left and right sides of the clothing section 10. Here, a fan having a propeller is used as the blower 20.

  An inner pocket (not shown) for accommodating the power supply is provided inside the clothing section 10. The power supply means is for supplying power to the two blowing means 20, 20. As the power supply means, for example, a power supply device containing a battery is used. The power supply means and the two blowing means 20, 20 are electrically connected by a power cable.

  The air discharge unit 30 is for discharging air flowing in a space (air flow passage) between the clothing unit 10 and the body or underwear to the outside. Specifically, the cuffs and the neck circumference of the garment part 10 play the role of the air discharge part 30.

  The helmet-compatible air-conditioning garment 1 of the first embodiment can be used not only when wearing a helmet, but also when not wearing a helmet. When the user does not wear the helmet, the user wears the clothes section 10 and closes the zipper, and then activates the two air blowing means 20, 20, as shown in FIG. 20 and 20 are taken into the clothing section 10. Then, the taken-in air flows upward in the air flow passage substantially in parallel with the body, and is discharged from the air discharge portion 30 around the neck and the cuffs. While such air is flowing through the air flow passage, the sweat emanating from the body is vaporized, and the temperature of the body surface can be reduced by the heat of vaporization when the sweat vaporizes. Therefore, in order for the helmet-compatible air-conditioning garment 1 to be able to efficiently perform its cooling function, the resistance of the air flowing through the air flow passage from the air discharge unit 30 is reduced, and a large amount of air is discharged. Must be distributed substantially parallel to the body. As one means for that purpose, as shown in FIG. 3, a set of adjusting cords 13 for increasing or decreasing the distance between the back of the user's neck and the back of the collar 12 of the garment 10 are provided on the garment 10. Is provided. The end of each adjustment cord 13 is attached to the inner surface of the rear collar portion 12 of the clothing section 10. By tying one set of adjustment cords 13 and adjusting the length appropriately, the size of the opening formed between the back of the neck and the back of the collar 12 can be made appropriate. A large amount of air flowing through the air flow passage can be ejected upward from the large opening. The opening formed between the rear part of the neck and the rear part of the collar 12 is one of the air discharge parts 30 and is also the ejection part 60 in the present invention.

When a general work is performed while wearing the helmet-compatible air-conditioning garment 1, the length of the adjustment cord 13 is adjusted to set the area of the ejection part 60 to about 10 cm ² . In addition, the rotation speed of the two blowing means 20, 20 is adjusted so that about 20 liters / second of air is taken into the clothing section 10 from outside. At this time, of the air of about 20 liters / second taken in from the two blowing means 20, 20, about 12 liters / second of air is discharged from the cuffs and the front of the neck, and the remaining about 8 liters / second of air is provided. Is discharged from the ejection part 60.

  Most of those who wear the helmet-compatible air-conditioning clothing 1 are also helmet wearers. Therefore, if the air ejected from the ejection section 60 of the clothing section 10 can be effectively taken into the helmet, the person wearing the helmet-compatible air-conditioning garment 1 is freed from the problem of helmet stuffiness, and the ejected air is further discharged to the rear of the neck. , The back of the neck and the back of the head can also be cooled. Since the helmet-compatible air-conditioning garment 1 of the first embodiment includes the guide sheet 70 and the attachment means 80, the air squirting upward from the squirting part 60 of the clothing part 10 can be taken into the helmet along the back of the neck. It has become. That is, the helmet-compatible air-conditioning garment 1 has a function of ventilating the inside of the helmet.

  In the helmet-compatible air-conditioning garment 1, the air taken into the garment portion 10 inflates the garment portion 10, and the garment portion 10 inflates to form an air flow passage between the garment portion 10 and the body or underwear. Designed for For this reason, especially at the back of the garment section 10, air circulates at a portion far away from the body, and this air does not contribute much to evaporating the sweat from the body. Therefore, the air spouting from the spouting section 60 has not deteriorated much in terms of temperature and humidity, and is still in a state that is sufficiently effective to evaporate sweat from the body.

  The guide sheet 70 is for guiding the air ejected from the ejection section 60 along the rear part and back of the user's neck and leading to the helmet 110. One end of the guide sheet 70 is continuous with the collar rear portion 12 of the clothing portion 10. That is, the clothing section 10 and the guide sheet 70 are integrated. Actually, as shown in FIG. 1, the shape of the guide sheet 70 is such that a portion covering the upper part of the head is removed from a hood provided in a raincoat or the like.

  On the other hand, an attachment means 80 is attached to the leading end of the guide sheet 70. The attachment means 80 is for attaching the guide sheet 70 to the helmet 110. Here, a loop-shaped belt having elasticity is used as the attachment means 80 as shown in FIGS. FIG. 4 is a schematic side view showing a state where the user wears a general work helmet 110. As shown in FIG. 4, a general work helmet 110 has a flange 111. As shown in FIG. 1B, the loop-shaped belt serving as the attachment means 80 is fitted to a side peripheral portion 112 of the helmet 110 along the flange 111.

  By the way, as shown in FIG. 4, on the outer surface of the helmet 110, notation information 113 such as the name of the person wearing the helmet 110, company name, work content, and the like is usually written. It is important for safety work. In the first embodiment, the width of the belt as the attachment means 80 is made as small as possible so that the belt does not obscure the notation information 113 as much as possible. Specifically, when the attaching means 80 is attached to the helmet 110, the attaching means 80 covers 20% of the entire outer surface of the helmet 110 even if the proportion of the covering of the outer surface of the helmet 110 is large. You are designing a certain belt size.

  As described above, the spouting portion 60 is an opening formed between the rear portion of the neck of the user and the rear portion 12 of the collar of the clothing portion 10, and the air circulating in the air flow passage is supplied to the spouting portion 60. Through the guide sheet 70. In the first embodiment, since the clothes section 10 and the guide sheet 70 are integrated, the position of the ejection section 60 cannot be clearly specified, but by definition, the clothes corresponding to the back of the neck of the user. The part of the part 10 can be regarded as the ejection part 60.

  Further, as shown in FIG. 1, a slack portion 14 formed by giving a slack to the cloth of the clothing portion 10 is provided in the upper part of the clothing portion 10 and from the blowing means 20 to the ejection portion 60. Have been. Here, as shown in FIG. 1A, the portion where the slack portion 14 is provided extends in the vertical direction in the upper back portion of the clothing portion 10, that is, from the center of the back of the clothing portion 10 to the guide sheet. 70 to the center. Specifically, both ends of the slack portion 14 are sewn to the clothing portion 10 by five slack forming cords 141. Thus, when the outside air is taken into the clothes section 10 by the blowing means 20, the slack portion 14 expands to the outside of the clothes section 10 by the taken air.

Next, a method of using the helmet-compatible air-conditioning garment 1 when the helmet 110 is worn will be described.
The user first wears the clothing section 10 and then wears a helmet 110. Thereafter, the user lifts the guide sheet 70 of the helmet-compatible air-conditioning garment 1 so as to cover the back of the neck and the back of the head, and fits the loop-shaped belt, which is the attachment means 80, into the side peripheral portion 112 of the helmet 110. Thus, the user can easily attach the guide sheet 70 to the helmet 110.

  When the blowing means 20, 20 are operated, external air is taken from the blowing means 20, 20 into the air flow passage of the helmet-compatible air-conditioning garment 1 and circulates toward the cuffs (the air discharge section 30) and the ejection section 60. I do. In the first embodiment, since the slack portion 14 is provided at the upper back portion of the clothing portion 10 and at the portion from the blowing means 20 to the jetting portion 60, when the blowing means 20, 20 are operated, the slack portion 14 becomes By inflating, a large amount of air can be collected in the slack portion 14. That is, as shown in FIG. 1C, the slack portion 14 becomes an air guide path having a cross section larger than the cross sections of the other air circulation portions. Therefore, a large amount of the collected air can be guided from the slack portion 14 serving as the air guide path to the jetting portion 60. In addition, since the guide sheet 70 is continuous with the rear collar portion 12 of the clothing section 10, a large amount of air spouted from the spouting section 60 is efficiently guided to the helmet 110 along the guide sheet 70, and is used with the inner edge of the helmet 110. The helmet 110 can be introduced into the helmet 110 through an air inlet 114 formed between the helmet 110 and the person's head. By introducing the air into the helmet 110 in this manner, the inside of the helmet 110 can be ventilated.

  In the first embodiment, by providing the slack portion 14 on the upper back of the clothing portion 10, it is possible to secure a sufficiently large area as the ejection portion 60 when the blowing means 20, 20 is operated. Therefore, it is not necessary to provide the adjustment cord 13 in the helmet-compatible air-conditioning garment 1.

  In the helmet-compatible air-conditioning garment of the first embodiment, by circulating the air in the air flow passage using the blowing means, the circulating air vaporizes the sweat that has come out of the body, and the vaporization when the sweat is vaporized The user's body can be cooled by the heat. In addition, since the guide sheet is provided so as to be continuous with the rear part of the collar of the clothing part, when the helmet is worn, air spouting from the spouting part is applied to the helmet inside the guide sheet along the back of the neck and the back of the user's head. I can guide you. For this reason, the sweat flowing out of the user's back and back of the neck can be vaporized by the air circulating inside the guide sheet, and the back and back of the neck can be cooled. And the inside of the helmet can be ventilated efficiently, so that the stuffiness of the user's head can be sufficiently eliminated.

  Further, in the first embodiment, the air blow means is operated by providing a slack portion formed by allowing the cloth to be slack in the upper part of the clothing portion and the portion from the blow means to the jetting portion. When air is allowed to flow through the air flow passage, the slack part expands, and a large amount of air can be collected in the slack part. Can be increased.

  Furthermore, in the first embodiment, when the attaching means is attached to the helmet, the attaching means covers 20% of the entire outer surface of the helmet even if the ratio of covering the outer surface of the helmet is large. It is possible to avoid a situation in which the notation information such as the name of the person wearing the helmet, the company name, and the like is completely covered and hidden by the attaching means, and another person cannot recognize the display information.

  In the first embodiment, a case has been described in which a loop-shaped belt having elasticity is used as the attachment means. However, in general, the attachment means is not limited to the above-described configuration, and is attached to the side peripheral portion of the helmet. Any configuration may be used as long as the side peripheral portion can be tightened. FIG. 5 is a schematic front view showing a modification of the attachment means in the helmet-compatible air-conditioning garment of the first embodiment. As shown in FIG. 5, a mounting means 800 according to this modified example includes a belt 810 disposed at a leading end of the guide sheet 70 substantially in parallel with the leading end thereof, and two flat surfaces provided at both ends of the belt 81. Fasteners 820, 820. As the belt 810, a belt made of transparent soft vinyl chloride is used. Since the belt 810 made of soft vinyl chloride fits and adheres well to the surface of the helmet, the mounting means 800 can be steadily attached to the helmet. In addition, since the belt 810 is transparent, even if the belt 810 overlaps the display information when the mounting means 800 is mounted on the helmet, others can recognize the display information. In this regard, it is generally desirable that the attachment means in the helmet-compatible air-conditioning garment of the present invention be transparent.

  Further, as the attaching means, a means having an elastic string provided at the distal end of the guide sheet and two hooks (mutual attaching means) attached to the distal end of the string may be used. . In this case, the guide sheet can be attached to the helmet by wrapping the string around the side periphery of the helmet and attaching the two hooks to each other. Further, as the attaching means, a loop-shaped string having elasticity provided at the leading end of the guide sheet may be used.

  Further, in the modification of the attaching means shown in FIG. 5, the length of the belt of the attaching means may be shortened. In this case, a surface fastener is provided in advance at a position on the side of the helmet opposite to the surface fastener provided at both ends of the belt, and the surface fastener provided at the end of the belt and the surface provided on the helmet are provided. The guide sheet can be attached to the helmet by attaching the zipper. As described above, the length of the attachment means does not necessarily need to be such a length as to go around the side peripheral portion of the helmet.

[Second embodiment]
Next, a helmet-compatible air-conditioning garment according to a second embodiment of the present invention will be described. 6A is a schematic rear view of a helmet-compatible air-conditioning garment according to a second embodiment of the present invention, FIG. 6B is a schematic side view of the helmet-compatible air-conditioning garment, and FIG. It is a general | schematic BB arrow direction general | schematic partial sectional view of clothing. In the second embodiment, components having the same functions as those of the first embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.

  As shown in FIG. 6, the helmet-compatible air-conditioning garment 1a according to the second embodiment has a garment section 10, two blowing means 20, 20, an air discharging section 30, a power supply means (not shown), and a power cable (not shown). (Not shown), a jetting section 60, a guide sheet 70, and an attaching means 80 a for attaching the guide sheet 70 to the helmet 110. Here, a slack portion 14 a formed by slackening the cloth is provided in the upper portion of the back of the clothing portion 10 and from the blowing means 20 to the ejection portion 60.

  The first difference between the helmet-compatible air-conditioning garment 1a of the second embodiment and the helmet-compatible air-conditioning garment of the first embodiment is that the attachment means 80a is connected to the leading end of the guide sheet 70 and substantially covers the entire helmet when the helmet is worn. This is a point where a hemispherical covering portion is used. Therefore, the mounting means 80a and the guide sheet 70 constitute a hood as a whole.

  Here, a hood adjustment cord 91 for adjusting the opening degree of the hood is provided at the edge of the hood, as shown in FIG. 6B. After putting on the hood from above the helmet 110, the user tightens the hood adjustment string 91. By properly tightening the hood adjustment cord 91, the hood can be firmly attached to the helmet 110 and the distance between the helmet 110 and the hood can be reduced. For this reason, the amount of air discharged from between the helmet 110 and the hood can be reduced, so that the air ejected from the ejection unit 60 can be efficiently introduced into the helmet 110. Note that the hood adjustment string 91 can be omitted.

  The second difference between the helmet-compatible air-conditioning garment 1a of the second embodiment and that of the first embodiment is that the helmet-compatible air-conditioning garment 1a has a substantially rectangular slack having substantially the same vertical length as the slack portion 14a. The slack portion 14a is formed by sewing the cloth 142 to the clothing portion 10. Here, as a material of the slack forming cloth 142, a coarse mesh material is used. Since the slack portion 14a is formed by using the slack forming cloth 142 having a substantially rectangular shape as described above, the slack portion 14a has a continuously expanded shape, so that the external appearance of the helmet-compatible air-conditioning garment 1a is improved. .

  The helmet-compatible air-conditioning garment of the second embodiment has the same functions and effects as the helmet-compatible air-conditioning garment of the first embodiment.
