- the ventilator body may be fixed to the body-worn article such that the air hole of the tube opens downwards when the body-worn article is in its normal orientation during wearing.
- a ventilator body fixed to the chest portion of a rainwear garment is oriented such that the air hole of the tube opens downwards towards a waist region of a wearer.
- the ventilating structure can further prevent water intrusion into the tube.
- the ventilator body may be fixed to the body-worn article such that the air hole of the tube is spaced apart from the vent.
- the air hole of the ventilator is spaced apart from the vent of the body-worn article, so that the ventilating structure can prevent water intrusion into the body-worn article further effectively.
- a ventilating structure ⁇ described here as an example includes a pair of vents 110 formed in rainwear item 100, which is a type of clothing (corresponding to a body-worn article), for keeping the moisture and temperature inside the rainwear item 100 low, and a pair of ventilators 1 fixed onto an outer surface of the rainwear item 100 in such a manner as to cover the vents 110.
- Fig. 1 illustrates only one of the ventilators 1 with the associated one of the vents 110, and that the following description is provided for one of the ventilators 1 and one of the vents 110 for the convenience of description.
- the vent 110 of the ventilator 1 consists of a rectangular hole opened a certain distance below an armpit portion of the rainwear item 100 and a piece of mesh fabric attached to the margins of the rectangular hole to cover the hole.
- Ventilation is achieved by releasing water (moisture) excreted from the upper body of the wearer of the rainwear item 100 to the outside through the vents 110 and by allowing outside air into the rainwear item 100 through the vents 110.
- Such ventilation is aided by the ventilators I fixed around the vents 110 of the rainwear 100.
- the ventilator 1 includes a ventilator body 10 to cover the vent 110.
- the ventilator body 10 in the embodiment is made of semi-transparent material such as synthetic resin so as to be visually unobtrusive.
- the material is as flexible (pliable) as the fabric forming the rainwear item 100 and sewable around the vent 110 of the rainwear item 100.
- the ventilator body 10 is fabricated integrally using a die. In other words, the ventilator body 10 has a shape suitable for being made by punching.
- the ventilator body 10 is fixed to the rainwear item 100 such that air holes 13 at open ends 122 of tubes 12 (to be described) are open downwards, i.e. in the rainfall direction when the rainwear item is in its normal orientation during wearing.
- the ventilator 1 is shown positioned below the attachment point of the sleeve of the rainwear item 100 adjacent to the chest portion, and is oriented such that the air holes 13 open downwards towards the bottom of the rainwear item.
- the ventilator body 10 is fixed to the rainwear 100 such that the air holes 13 of the tubes 12 are offset in a direction away from the center O of the vent 110.
- the ventilator body 10 may be attached to any position of the rainwear 100 as long as the air holes 13 of the tubes 12 are positioned a distance away from the vent 110.
- the ventilator body 10 includes a plate-like base 11, a plurality of tubes 12, a plurality of air holes 13, a plurality of walls 124 (corresponding to water intrusion prevention means), and a plurality of through holes 125 as shown in Fig. 2A to Fig. 2J .
- the base 11 includes a front face 111, a back face 112, frame-like edge 113 (see Fig. 2B ), and a plurality of openings 114.
- the front face 111 of the base 11 is proved with the plurality of tubes 12 aligned along a widthwise direction of the base.
- the openings 114 are through-holes passing from the front face to the back face of the base 11, arranged in correspondence with the tubes 12.
- the edge 113 is sewn to the rainwear 100 with thread or the like.
- Each tube 12 is a generally tuboid member cut in half longitudinally such as to have an opening 114 opening on the side of the back face 112 of the base 11.
- a lengthwise end (open end 122) of each tube 12 has a beveled opening (air hole 13).
- the other lengthwise end (closed end 123) of the tube 12 is curved and closed.
- each tube 12 forms a moist air passage 121.
- the moist air passage 121 extends in the lengthwise direction of the tube 12.
- the tubes 12 are entirely open as the openings 114 of the base 11 on the back face 112 of the base 11.
- the air holes 13 in the open ends 122 of the tubes 12 each communicate with an end of the associated moist air passage 121. These ends of moist air passages 121 release moisture through the air holes 13 and take in outside air therefrom (see Fig. 1 ).
- each tube 12 has a total of four walls 124 that are arranged alternately on the left and right and spaced apart in the lengthwise direction on the inside of the tube 12 (arranged in a staggered and spaced relation to each other inside the tube along a lengthwise direction of the tube 12).
- the tube 12 may be formed to have at least one wall 124 therein.

The remaining regions of the openings 114 (regions facing the vent 110) communicate with the vent 110.
- the walls 124 serve to block a large part of water entering the moist air passages 121 from the air holes 13. However, as the walls 124 block the moist air passages 121 only partially, they do not inhibit air circulation in the moist air passages 121.
- Each tube 12 also has a sloped surface 126 as shown in Fig. 2E sloping down from the open end 122 toward the closed end 123 for facilitating intake of outside air.
- a flow of outside air received on the sloped surface 126 creates a negative pressure inside the tube 12, as a result of which the air flow is maintained for a relatively long period of time.
- the slope angle of the sloped surface 126 may be set in accordance with how much ventilation is desirable.
- each tube 12 has a total of three through holes 125 spaced apart in the lengthwise direction of the tube 12. The diameter and number of each through hole 125 may be suitably set to achieve a desired internal pressure of the moist air passage 121.
- the ventilating structure ⁇ described above has the ventilators 1 to cover the vents 110 of the rainwear 100, favorably providing ventilation with the rainwear 100 more effectively than ventilation provided by a conventional moisture-permeable rainwear. Moreover, the structure ⁇ keeps the inside of the rainwear 100 dry and comfortable because of invulnerability to water intrusion as described in detail below. The ventilating structure ⁇ also has a huge cost advantage because the ventilators 1 are formed in one piece and attachable to the rainwear 100 by sewing in the course of production of the rainwear 100.
- the ventilating structure ⁇ provides the invulnerability to intrusion of water such as raindrops by the combination of the following features (1) to (5):
- the walls 124 used as the water intrusion prevention means can prevent water intrusion without inhibiting air circulation in the moist air passages 121.
- the ventilator body 10 may be designed to further have a bent middle portion 127 (bent once or twice or more in a zigzag fashion), as with ventilators 1', 1", 1'" according to first, second, and third modified examples as shown in Fig. 3 to Fig. 5 .
- How water that has entered the moist air passages 121 collects depends on the direction or the number of times of bending in the middle portion 127, and therefore changing these factors can further enhance the water intrusion preventing effect.
- the modified examples mentioned above are configured basically the same as the previously described embodiment except for the middle portion 127 of the ventilator body 10, and therefore will not be described again.
- the ventilator and the ventilating structure according to the present invention are applicable not only to rainwear but also to any other commonly used body-worn articles (such as inner wear and other garments including hooded jackets, trousers and the like, hats, and footwear).
- the position, shape and other configurations of the vents to be formed in such body-worn articles may be suitably selected in accordance with the types of the articles.
- the vent may be modified into just an opening, an opening provided with a piece of mesh fabric, or an opening enforced with a grommet-like member.
- the ventilating structure may include at least one vent and at least one ventilator.
- the base of the ventilator body may be variously changed in shape and design depending on how it is attached to a body-worn article.
- the base may be modified such that its edge is in such a shape as to be more suitable for the attachment to the body-worn article by thermal compression bonding.
- the tubes may be provided in any number (one, two or more).
- the tubes may be modified in shape to have circular, square, or any other cross-sectional shapes.
- the tubes may be modified to have curved, bent, zigzag, crossed, or any other lengthwise shapes.
- the tubes may be all oriented in the same direction, or some or all of the tubes may be oriented in different directions.
- the air holes of the tubes may be formed sideways or any other part of the tubes.

- The ventilator body may be fixed to the body-worn article such that the air hole of the tube opens downwards when the body-worn article is in its normal orientation during wearing. For example, a ventilator body fixed to the chest portion of a rainwear garment is oriented such that the air hole of the tube opens downwards towards a waist region of a wearer.
- According to this aspect of the invention, as the air hole of the tube opens downwards, raindrops falling from above are unlikely to enter the tube through the air hole. Therefore, the ventilating structure can further prevent water intrusion into the tube.
- If the moist air passage of the tube is entirely open on the back face side of the base, the ventilator body may be fixed to the body-worn article such that the air hole of the tube is spaced apart from the vent.
- According to this aspect of the invention, the air hole of the ventilator is spaced apart from the vent of the body-worn article, so that the ventilating structure can prevent water intrusion into the body-worn article further effectively.

Fig. 1 to Fig. 2J . As shown inFig. 1 , a ventilating structure α described here as an example includes a pair ofvents 110 formed inrainwear item 100, which is a type of clothing (corresponding to a body-worn article), for keeping the moisture and temperature inside therainwear item 100 low, and a pair ofventilators 1 fixed onto an outer surface of therainwear item 100 in such a manner as to cover thevents 110. Note thatFig. 1 illustrates only one of theventilators 1 with the associated one of thevents 110, and that the following description is provided for one of theventilators 1 and one of thevents 110 for the convenience of description. - In this embodiment, the
vent 110 of theventilator 1 consists of a rectangular hole opened a certain distance below an armpit portion of therainwear item 100 and a piece of mesh fabric attached to the margins of the rectangular hole to cover the hole. - Ventilation is achieved by releasing water (moisture) excreted from the upper body of the wearer of the
rainwear item 100 to the outside through thevents 110 and by allowing outside air into therainwear item 100 through thevents 110. Such ventilation is aided by the ventilators I fixed around thevents 110 of therainwear 100. - The
ventilator 1 includes aventilator body 10 to cover thevent 110. Theventilator body 10 in the embodiment is made of semi-transparent material such as synthetic resin so as to be visually unobtrusive. The material is as flexible (pliable) as the fabric forming therainwear item 100 and sewable around thevent 110 of therainwear item 100. Theventilator body 10 is fabricated integrally using a die. In other words, theventilator body 10 has a shape suitable for being made by punching. - The
ventilator body 10 is fixed to therainwear item 100 such that air holes 13 atopen ends 122 of tubes 12 (to be described) are open downwards, i.e. in the rainfall direction when the rainwear item is in its normal orientation during wearing. For example, inFig. 1 theventilator 1 is shown positioned below the attachment point of the sleeve of therainwear item 100 adjacent to the chest portion, and is oriented such that the air holes 13 open downwards towards the bottom of the rainwear item. Theventilator body 10 is fixed to therainwear 100 such that the air holes 13 of thetubes 12 are offset in a direction away from the center O of thevent 110. In other words, theventilator body 10 may be attached to any position of therainwear 100 as long as the air holes 13 of thetubes 12 are positioned a distance away from thevent 110. - The
ventilator body 10 includes a plate-like base 11, a plurality oftubes 12, a plurality ofair holes 13, a plurality of walls 124 (corresponding to water intrusion prevention means), and a plurality of throughholes 125 as shown inFig. 2A to Fig. 2J . - The
base 11 includes afront face 111, aback face 112, frame-like edge 113 (seeFig. 2B ), and a plurality ofopenings 114. Thefront face 111 of thebase 11 is proved with the plurality oftubes 12 aligned along a widthwise direction of the base. - In this embodiment, there are six
tubes 12 aligned along the widthwise direction. Theopenings 114 are through-holes passing from the front face to the back face of thebase 11, arranged in correspondence with thetubes 12. Theedge 113 is sewn to therainwear 100 with thread or the like. - Other embodiments (not shown) may have a different number of
tubes 12. - Each
tube 12 is a generally tuboid member cut in half longitudinally such as to have anopening 114 opening on the side of theback face 112 of thebase 11. As shown inFig. 2D ,Fig. 2E, and Fig. 2F , a lengthwise end (open end 122) of eachtube 12 has a beveled opening (air hole 13). As shown inFig. 2C ,Fig. 2E, and Fig. 2F , the other lengthwise end (closed end 123) of thetube 12 is curved and closed. - The space inside each
tube 12 forms amoist air passage 121. Themoist air passage 121 extends in the lengthwise direction of thetube 12. In this embodiment, as shown inFig. 2B , the tubes 12 (moist air passages 121) are entirely open as theopenings 114 of the base 11 on theback face 112 of thebase 11. The air holes 13 in the open ends 122 of thetubes 12 each communicate with an end of the associatedmoist air passage 121. These ends ofmoist air passages 121 release moisture through the air holes 13 and take in outside air therefrom (seeFig. 1 ). - The
walls 124 are provided in eachtube 12. Thewalls 124, as shown inFig. 2B , are blades to partly block themoist air passage 121 inside thetube 12. In this embodiment, eachtube 12 has a total of fourwalls 124 that are arranged alternately on the left and right and spaced apart in the lengthwise direction on the inside of the tube 12 (arranged in a staggered and spaced relation to each other inside the tube along a lengthwise direction of the tube 12). Thetube 12 may be formed to have at least onewall 124 therein. - The
moist air passages 121 of thetubes 12 are entirely open as theopenings 114 of the base 11 as mentioned above. It should be noted that, as shown inFig. 1 , with theventilator 1 fixed on therainwear 100, regions of theopenings 114 between the air holes 13 and thevent 110 are covered by the front side of the fabric of therainwear 100. The remaining regions of the openings 114 (regions facing the vent 110) communicate with thevent 110. Thewalls 124 serve to block a large part of water entering themoist air passages 121 from the air holes 13. However, as thewalls 124 block themoist air passages 121 only partially, they do not inhibit air circulation in themoist air passages 121. - Each
tube 12 also has a slopedsurface 126 as shown inFig. 2E sloping down from theopen end 122 toward theclosed end 123 for facilitating intake of outside air. A flow of outside air received on thesloped surface 126 creates a negative pressure inside thetube 12, as a result of which the air flow is maintained for a relatively long period of time. The slope angle of the slopedsurface 126 may be set in accordance with how much ventilation is desirable. - A plurality of through holes 125 (apertures) is formed in the outer wall of each
tube 12 for aiding ventilation, more particularly between theair hole 13 and thewalls 124 as shown inFig. 2A and Fig. 2B . In this embodiment, eachtube 12 has a total of three throughholes 125 spaced apart in the lengthwise direction of thetube 12. The diameter and number of each throughhole 125 may be suitably set to achieve a desired internal pressure of themoist air passage 121. - The ventilating structure α described above has the
ventilators 1 to cover thevents 110 of therainwear 100, favorably providing ventilation with therainwear 100 more effectively than ventilation provided by a conventional moisture-permeable rainwear. Moreover, the structure α keeps the inside of therainwear 100 dry and comfortable because of invulnerability to water intrusion as described in detail below. The ventilating structure α also has a huge cost advantage because theventilators 1 are formed in one piece and attachable to therainwear 100 by sewing in the course of production of therainwear 100. - The ventilating structure α provides the invulnerability to intrusion of water such as raindrops by the combination of the following features (1) to (5):
- (1) The air holes 13 are arranged at different positions and open in different directions from those of the
vents 110 of therainwear 100; - (2) The
tubes 12 are shaped such as to have the air holes 13 of relatively small opening areas; - (3) The
tubes 12 are each provided with the water intrusion prevention means; - (4) The straight line distances from the air holes 13 to the associated
vents 110 are relatively long; and - (5) The air holes 13 open downwards when a user wears the
rainwear 100. - In addition, the
walls 124 used as the water intrusion prevention means can prevent water intrusion without inhibiting air circulation in themoist air passages 121. - To further enhance the water intrusion preventing effect, the
ventilator body 10 may be designed to further have a bent middle portion 127 (bent once or twice or more in a zigzag fashion), as withventilators 1', 1", 1'" according to first, second, and third modified examples as shown inFig. 3 to Fig. 5 . How water that has entered themoist air passages 121 collects depends on the direction or the number of times of bending in themiddle portion 127, and therefore changing these factors can further enhance the water intrusion preventing effect. The modified examples mentioned above are configured basically the same as the previously described embodiment except for themiddle portion 127 of theventilator body 10, and therefore will not be described again. - The ventilator and the ventilating structure according to the present invention are applicable not only to rainwear but also to any other commonly used body-worn articles (such as inner wear and other garments including hooded jackets, trousers and the like, hats, and footwear). The position, shape and other configurations of the vents to be formed in such body-worn articles may be suitably selected in accordance with the types of the articles. The vent may be modified into just an opening, an opening provided with a piece of mesh fabric, or an opening enforced with a grommet-like member. The ventilating structure may include at least one vent and at least one ventilator.
- The base of the ventilator body may be variously changed in shape and design depending on how it is attached to a body-worn article. For example, the base may be modified such that its edge is in such a shape as to be more suitable for the attachment to the body-worn article by thermal compression bonding. The tubes may be provided in any number (one, two or more). The tubes may be modified in shape to have circular, square, or any other cross-sectional shapes. The tubes may be modified to have curved, bent, zigzag, crossed, or any other lengthwise shapes. The tubes may be all oriented in the same direction, or some or all of the tubes may be oriented in different directions. The air holes of the tubes may be formed sideways or any other part of the tubes. The inner spaces of the tubes may be entirely open on the back face side of the base or may be partly open (i.e. the openings of the base are formed as partial openings of the tubes). The tubes may be open at both longitudinal ends to form air holes. The tubes may not necessarily include the water intrusion prevention means. The water intrusion prevention means may be curved or bent moist air passages themselves serving as the water intrusion prevention means, or compartments or the like provided in the passages for collecting intruding water, or passageways provided in the passages for draining water outside.
