Description

The present invention relates to a garment body of an air-conditioned garment and an air-conditioned garment.

In recent years, air-conditioned garments that evaporate sweat emitted from the body by circulating a large amount of outside air substantially parallel to the surface of the body or underwear have been put into practical use. A detailed description of the principle and structure of the air-conditioned garment is described in detail in, for example, Patent Document 1. In addition, many people who wear air-conditioned clothes also wear helmets. In this case, wearing air-conditioned clothes eliminates the stuffiness of the body, but eliminates the stuffiness of the head when wearing the helmet. It is not possible.

Further, in recent years, a device 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 the outer edge of the helmet and the outside air taken in by the blower is sent into the helmet by an introduction pipe.

Japanese Unexamined Patent Publication No. 2005-54299

However, the device for adding the ventilation function to the above-mentioned work helmet has the following major performance problems. First, since the device is attached directly to the helmet, it is not possible to use one that has a blower that is too large in terms of weight. Therefore, a large amount of air cannot be sent into the helmet, and the stuffiness of the head cannot be sufficiently eliminated. Secondly, 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 made very 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, the power consumption is proportional to the square of the wind speed, so if the wind speed is increased, the battery will be consumed immediately.

The present invention has been made based on the above circumstances, and provides a garment body of an air-conditioned garment and an air-conditioned garment that can sufficiently eliminate not only the stuffiness of the body but also the stuffiness of the user's head when wearing a helmet. The purpose is to do.

In order to achieve the above object, the present invention covers at least the upper body of the user's body, and includes a garment portion provided with a blower means attachment portion for attaching a blower means for introducing air into the body, and a user's neck. It is provided with an ejection portion for ejecting air introduced by the blowing means from the rear of the garment portion, and a portion extending from the upper back of the garment portion to the ejection portion is formed by giving a slack to the cloth of the garment portion. It is characterized in that a loosened portion is provided.

In the garment body and the air-conditioned garment of the air-conditioned garment according to the present invention, when air is circulated inside the garment body by using a blowing means, the circulated air vaporizes the sweat emitted from the body, and the sweat is vaporized. The heat of vaporization can cool the user's body. Moreover, when the helmet is worn, the inside of the helmet can be ventilated, so that the stuffiness of the user's head can be sufficiently eliminated.

According to the clothes body and the air-conditioned clothes of the air-conditioned clothes according to the present invention, the inside of the helmet can be ventilated, so that the stuffiness of the user's head can be sufficiently eliminated.

Hereinafter, modes for carrying out the invention according to the present application will be described with reference to the drawings.

[First Embodiment]
First, the first embodiment of the present invention will be described with reference to the drawings. 1 (a) is a schematic rear view of a helmet-compatible air-conditioned garment according to the first embodiment of the present invention, FIG. 1 (b) is a schematic side view of the helmet-compatible air-conditioned garment, and FIG. 1 (c) is a helmet-compatible air-conditioned garment. Schematic diagram of clothing AA is a schematic partial cross-sectional view in the direction of the arrow. Further, FIG. 2 is a diagram for explaining the air flow in the helmet-compatible air-conditioned clothing, and FIG. 3 is a diagram for explaining a ejection portion in the helmet-compatible air-conditioning clothing.

The helmet-compatible air-conditioned garment of the first embodiment can be used both when the helmet is worn and when it is not worn. As shown in FIGS. 1, 2 and 3, the helmet-compatible air-conditioned garment 1 includes a garment portion 10, two blowing means 20 and 20, an air discharging portion 30, a power supply means (not shown), and a power source. A cable (not shown), a ejection portion 60, a guide sheet 70, and an attachment means 80 for attaching the guide sheet 70 to the helmet 110 are provided. Note that 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 garment portion 10 is a sheet-like material having little or no breathability, and is formed in a shape that covers the upper body and the arms. A stretchable member such as rubber is attached to the hem portion 11 of the garment portion 10. As a result, the hem portion 11 of the garment portion 10 is narrowed down and comes into close contact with the body or underwear. Further, a fastener (not shown) as an opening / closing means is provided on the front side of the garment portion 10. This fastener is for opening and closing the front portion of the garment portion 10 when it is worn.

The air blowing means 20 forms an air flow passage between the clothing portion 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 and 20 are attached to the lower part of the garment portion 10 and to the left and right side portions. Here, as the blowing means 20, a fan having a propeller is used.

Further, an inner pocket (not shown) for accommodating the power supply means is provided inside the garment portion 10. The power supply means is for supplying electric power to the two blowing means 20, 20. As the power supply means, for example, a power supply device having a built-in battery is used. The power supply means and the two ventilation means 20, 20 are electrically connected by a power cable.

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

The helmet-compatible air-conditioned garment 1 of the first embodiment can be used not only when the helmet is worn, but also when the helmet is not worn. When the user does not wear a helmet, the user wears the garment portion 10, closes the fastener, and then activates the two ventilation means 20 and 20, and as shown in FIG. 2, the outside air blows the two ventilation means. It is taken into the clothes portion 10 from 20 and 20. Then, the taken-in air circulates upward in the air flow passage substantially parallel to the body, and is discharged from the neck circumference portion and the cuff portion, which are the air discharge portions 30. While the air flows through the air flow passage, the sweat emitted from the body is vaporized, and the temperature of the body surface can be lowered by the heat of vaporization when the sweat vaporizes. Therefore, in order for the helmet-compatible air-conditioned garment 1 to be able to efficiently operate its cooling function, the resistance that the air flowing through the air flow passage receives from the air discharge unit 30 is reduced, and a large amount of air is used. Needs to be distributed approximately parallel to the body. As one means for that purpose, as shown in FIG. 3, the garment portion 10 has a set of adjusting strings 13 for widening or narrowing the distance between the rear portion of the neck of the user and the rear portion of the collar 12 of the garment portion 10. Is provided. The end of each adjusting string 13 is attached to the inner surface of the collar rear portion 12 of the garment portion 10. By tying a set of adjusting strings 13 and adjusting the length appropriately, the size of the opening formed between the rear part of the neck and the rear part of the collar 12 can be made appropriate. From this large opening, a large amount of air flowing through the air flow passage can be ejected upward. 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, but it is also the ejection part 60 in the present invention.

When a helmet-compatible air-conditioned garment 1 is worn for general work, the length of the adjusting string 13 is adjusted to set ^{the area of the ejection portion 60 to about 10 cm 2.} Further, the rotation speeds of the two blowing means 20 and 20 are adjusted so that air of about 20 liters / second is taken into the clothes portion 10 from the outside. At this time, of the approximately 20 liters / second of air taken in from the two blowing means 20, 20, approximately 12 liters / second of air is discharged from the cuffs and the front of the neck, and the remaining approximately 8 liters / second of air is discharged. Will be discharged from the ejection portion 60.

Most of the people who wear the helmet-compatible air-conditioned clothes 1 are also helmet wearers. Therefore, if the air ejected from the ejection portion 60 of the clothing portion 10 is effectively taken into the helmet, the person wearing the helmet-compatible air-conditioning clothing 1 is freed from the problem of stuffiness of the helmet, and the ejected air is further discharged from the back of the neck. Since it flows along the head, the back of the neck and the back of the head can also be cooled. By providing the guide sheet 70 and the mounting means 80, the helmet-compatible air-conditioned garment 1 of the first embodiment can take in the air ejected upward from the ejection portion 60 of the garment portion 10 into the helmet along the rear portion of the neck. It has become like. That is, the helmet-compatible air-conditioned garment 1 has a function of ventilating the inside of the helmet.

In the helmet-compatible air-conditioned 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 in the back of the garment portion 10, air also circulates in a portion considerably distant from the body, and this air does not contribute much to evaporate the sweat emitted from the body. Therefore, the air ejected from the ejection portion 60 has not deteriorated so much in terms of temperature and humidity, and is still in a sufficiently effective state for evaporating the sweat emitted from the body.

The guide sheet 70 is for guiding the air ejected from the ejection portion 60 along the back of the neck and the back of the head of the user and guiding the air to the helmet 110. One end of the guide sheet 70 is connected to the rear portion 12 of the collar of the garment portion 10. That is, the garment portion 10 and the guide sheet 70 are integrated. In fact, as shown in FIG. 1, the shape of the guide sheet 70 is such that the portion covering the upper part of the head is removed from the hood provided on the raincoat or the like.

On the other hand, the attachment means 80 is attached to the tip of the guide sheet 70. The attachment means 80 is for attaching the guide sheet 70 to the helmet 110. Here, as the mounting means 80, as shown in FIGS. 2 and 3, a loop-shaped belt having elasticity is used. FIG. 4 is a schematic side view showing a state when the user wears a general work helmet 110. As shown in FIG. 4, a general work helmet 110 has a collar 111. As shown in FIG. 1B, the loop-shaped belt, which is the attachment means 80, is fitted into the side peripheral portion 112 along the collar 111 of the helmet 110.

By the way, as shown in FIG. 4, notation information 113 such as the name, company name, work content, etc. of the person who wears the helmet 110 is usually written on the outer surface of the helmet 110, and these notation information 113 is It is important in terms of safe work, etc. In the first embodiment, the width of the belt, which is the mounting means 80, is made as small as possible so that the belt does not cover the notation information 113 as much as possible. Specifically, when the mounting means 80 is mounted on the helmet 110, the mounting means 80 covers 20% of the entire outer surface of the helmet 110 even if the proportion of the mounting means 80 covering the outer surface of the helmet 110 is large. I am designing the size of a certain belt.

As described above, the ejection 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 flowing through the air flow passage is the ejection portion 60. Will be ejected to the side of the guide sheet 70 via the guide sheet 70. In the first embodiment, since the garment portion 10 and the guide sheet 70 are integrated, the position of the ejection portion 60 cannot be clearly specified, but by definition, the garment corresponding to the back of the neck of the user. The portion of the portion 10 can be regarded as the ejection portion 60.

Further, as shown in FIG. 1, a slack portion 14 formed by giving slack to the cloth of the garment portion 10 is provided on the upper back portion of the garment portion 10 from the blowing means 20 to the ejection portion 60. Has been done. Here, as shown in FIG. 1A, the portion where the slack portion 14 is provided is a guide sheet from a range extending vertically in the upper back of the garment portion 10, that is, from the back center portion of the garment portion 10. It extends to the central part of 70. Specifically, both ends of the slack portion 14 are sewn to the garment portion 10 by five slack forming strings 141. As a result, when the outside air is taken into the garment portion 10 by the blowing means 20, the slack portion 14 swells to the outside of the garment portion 10 due to the taken-in air.

Next, a method of using the helmet-compatible air-conditioned garment 1 when wearing the helmet 110 will be described.
The user first wears the garment portion 10, and then wears the helmet 110. After that, the user lifts the guide sheet 70 of the helmet-compatible air-conditioned 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. In this way, the user can easily attach the guide sheet 70 to the helmet 110.

When the blower means 20 and 20 are operated, the outside air is taken into the air flow passage of the helmet-compatible air-conditioning garment 1 from the blower means 20 and 20 and flows toward the cuffs (air discharge part 30) and the ejection part 60. do. In the first embodiment, since the slack portion 14 is provided in the upper back of the garment portion 10 from the blower means 20 to the ejection portion 60, when the blower means 20 and 20 are operated, the slack portion 14 is formed. It swells and can collect a large amount of air in this slack portion 14. That is, as shown in FIG. 1 (c), the slack portion 14 is a wind guide having a cross section larger than that of the other air flow portions. Therefore, the large amount of collected air can be guided from the slack portion 14 as the air duct to the ejection portion 60. Further, since the guide sheet 70 is connected to the rear portion 12 of the collar of the clothing portion 10, a large amount of air ejected from the ejection portion 60 is efficiently guided to the helmet 110 along the guide sheet 70 and used with the inner edge of the helmet 110. It can be introduced into the helmet 110 through an air inlet 114 (see FIG. 4) formed between the person's head and the person's head. By introducing air into the helmet 110 in this way, 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 garment portion 10, it is possible to secure a sufficiently large area as the area of the ejection portion 60 when the blowing means 20 and 20 are operated. Therefore, it is not always necessary to provide the adjusting string 13 on the helmet-compatible air-conditioned garment 1.

In the helmet-compatible air-conditioned garment of the first embodiment, by circulating air in the air flow passage by using a blowing means, the circulating air vaporizes the sweat emitted from the body, and the sweat vaporizes when the sweat vaporizes. The heat can cool the user's body. Moreover, by providing the guide sheet so as to be connected to the rear part of the collar of the garment part, the air ejected from the ejected part is sent to the helmet along the back part of the neck and the back of the head of the user inside the guide sheet when the helmet is worn. Can be guided. Therefore, the sweat flowing from the back of the neck and the back of the head of the user can be vaporized by the air circulating inside the guide sheet to cool the back of the neck and the back of the head, and the air guided by the helmet can be taken into the helmet. Since it can be efficiently introduced into the helmet to ventilate the inside of the helmet, the stuffiness of the user's head can be sufficiently eliminated.

Further, in the first embodiment, the air blowing means is operated by providing a slack portion formed by giving slack to the fabric in the upper part of the back of the garment portion from the blowing means to the blowing portion. When air is circulated in the air flow passage, the slack part expands and a large amount of air can be collected in the slack part. The amount of air introduced into the helmet can be increased.

Further, in the first embodiment, when the mounting means is attached to the helmet, even if the mounting means covers the outer surface of the helmet at a large ratio, it is 20% of the entire outer surface of the helmet. It is possible to avoid a situation in which the written information such as the name of the person wearing the helmet and the company name is completely obscured by the mounting means and the displayed information cannot be recognized by others.

In the first embodiment, the case where a loop-shaped belt having elasticity is used as the mounting means has been described, but in general, the mounting means is not limited to the above configuration and is mounted on the side peripheral portion of the helmet. Moreover, any configuration may be used as long as the side peripheral portion can be tightened. FIG. 5 is a schematic front view showing a modified example of the mounting means in the helmet-compatible air-conditioned garment of the first embodiment. As shown in FIG. 5, the mounting means 800 of this modified example includes a belt 810 arranged substantially parallel to the tip of the guide sheet 70, and two surface shapes provided at both ends of the belt 81. It has fasteners 820 and 820. As the belt 810, a transparent soft vinyl chloride belt is used. Since the soft vinyl chloride belt 810 fits well and adheres to the surface of the helmet, the attachment means 800 can be steadily attached to the helmet. Moreover, since the belt 810 is transparent, even if the belt 810 overlaps the display information when the mounting means 800 is attached to the helmet, others can recognize the display information. In this respect, it is generally desirable that the mounting means in the helmet-compatible air-conditioned garment of the present invention be transparent.

Further, as the attachment means, one having an elastic string provided at the tip of the guide sheet and two hooks (mutual attachment means) attached to the tip 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 peripheral portion 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 tip of the guide sheet may be used.

Further, in the modified example of the mounting means shown in FIG. 5, the length of the belt of the mounting means may be shortened. In this case, a planar fastener is provided in advance on the side of the helmet at a position facing the planar fasteners provided at both ends of the belt, and the planar fastener provided at the end of the belt and the surface provided on the helmet. The guide sheet can be attached to the helmet by attaching it to the shape fastener. As described above, the length of the mounting means does not necessarily have to be such that it goes around the side peripheral portion of the helmet.

[Second Embodiment]
Next, the helmet-compatible air-conditioned garment according to the second embodiment of the present invention will be described. 6 (a) is a schematic rear view of the helmet-compatible air-conditioned garment according to the second embodiment of the present invention, FIG. 6 (b) is a schematic side view of the helmet-compatible air-conditioned garment, and FIG. 6 (c) is the helmet-compatible air-conditioned garment. It is a schematic partial cross-sectional view of the clothes in the direction of the arrow BB. In the second embodiment, those having the same functions as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

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

The first point that the helmet-compatible air-conditioned garment 1a of the second embodiment is different from that of the first embodiment is that the mounting means 80a is connected to the tip of the guide sheet 70 and covers substantially the entire helmet when the helmet is worn. This is a point where a hemispherical covering is used. Therefore, the mounting means 80a and the guide sheet 70 form a hood as a whole.

Here, as shown in FIG. 6B, a hood adjusting string 91 for adjusting the opening degree of the hood is provided at the edge portion of the hood. After covering the hood from above the helmet 110, the user tightens the hood adjusting string 91. By properly tightening the hood adjusting string 91, the hood can be firmly attached to the helmet 110, and the distance between the helmet 110 and the hood can be narrowed. Therefore, since the amount of air discharged from between the helmet 110 and the hood can be reduced, the air ejected from the ejection portion 60 can be efficiently introduced into the helmet 110. The hood adjusting string 91 can be omitted.

The second point that the helmet-compatible air-conditioned garment 1a of the second embodiment is different from that of the first embodiment is the formation of a substantially rectangular slack having a vertical length substantially the same as the vertical length of the slack portion 14a. The point is that the slack portion 14a is formed by sewing the cloth 142 to the garment portion 10. Here, as the material of the slack forming cloth 142, a coarse mesh material is used. By forming the slack portion 14a using the substantially rectangular slack forming cloth 142 in this way, the slack portion 14a has a continuously bulging shape, so that the appearance of the helmet-compatible air-conditioned garment 1a is improved. ..

The helmet-compatible air-conditioned garment of the second embodiment has the same action and effect as the helmet-compatible air-conditioned garment of the first embodiment.
