Accordingly, an object of the present invention is to release a body heat and moisture accumulated in the inside of the wear and to prevent the rainwater from entering, and a breathable cloth piece for wear and an upper sleeve and / or pants using the cloth piece. Providing breathable wear consisting of
The inventors of the present invention have arrived at the present invention as a result of intensive studies to achieve the above object.

That is, the present invention
(1) The upper and lower cloth pieces arranged on the upper and lower sides are provided with overlapping portions, the upper ends of the lower cloth pieces are folded outward to form a weir, and the tip of the folded weir A first vent hole between the folded weir and the upper cloth piece, and the upper cloth piece. A second vent is provided between the end of the upper fabric and the lower fabric piece, and the end of the upper fabric piece is connected to the lower fabric piece below the folded portion of the overlapping portion by connecting means. It is a breathable cloth piece for the wear characterized by this .
(2) The breathable cloth piece according to (1 ), wherein the overlapping portion is provided in two upper and lower stages.
(3) Breathable clothing characterized by using the breathable cloth piece described in (1) above on a sleeve of breathable clothing made of an upper garment.
(4) Breathable wear characterized by using the breathable cloth piece described in (1) above for breathable wear made of trousers.

The present invention will be described cuff below ependymal, breathable fabric piece and pants cuff is the same structure and cuffs ependymal, effect a description of the breathable fabric piece and cuffs are the same omitted To do.
The first feature of the present invention is that the cuff of the upper garment of the breathable wear has a double structure of the inner sleeve and the outer sleeve, and the inner sleeve with the end folded back outward is inserted into the cuff of the outer sleeve, The inner sleeve turn-up portion and the outer sleeve cuff are connected by a connecting means, and a first vent is provided between the outer sleeve and the inner sleeve turn-up portion, and the outer sleeve cuff is provided between the outer sleeve cuff and the inner sleeve. The second vent is provided . With this feature, when the second vent is enlarged, the folding angle of the V-shaped weir for preventing rainwater infiltration is enlarged by the connecting means, and raindrops pass through the weir from the first vent to the inside of the sleeve. Intrusion can be prevented. In addition, since the width of the first vent formed by the weir and the outer sleeve is narrowed in proportion to the expansion of the angle of the V-shaped weir, the strong wind entering from the second vent that is wide open is The narrowed first air vent serves as a resistance and can reduce the intrusion into the sleeve, and the amount of air passing through the first air vent can be adjusted to a constant amount regardless of the strength of the wind and rain. In addition, a large amount of air at the time of strong wind from entering the interior of the sleeve opening, can also prevent the cool the arm of wear wearer. In addition, the connecting member can prevent the cuff from being deformed. Furthermore, if the upper garment is provided with ventilation holes, for example, a plurality of ventilation holes on the side, the outside air introduced from the cuffs to the inside due to the venturi effect is caused by the body heat and moisture accumulated inside. Since it is discharged to the outside through a plurality of openings provided, even when wearing wear during exercise or work during the rainy season, it is difficult for the arm portion to peel off and sweating can be delayed.
The second feature of the present invention is to prevent the outside sleeve from rolling up and a large amount of outside air from entering the inside of the cuff during a strong wind. in, and is that the connection between the inner sleeve position lower than the folded portion connecting means, for example, in fabric narrow. Due to such characteristics, it is possible to prevent the outer sleeve from rolling up in a strong wind.

Next, an embodiment of the breathable wear of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram schematically showing an example of the front body of the upper garment of the breathable wear of the present invention, and FIG. 2 is a schematic diagram schematically showing an example of the back of the upper garment shown in FIG. 3 is a schematic diagram schematically showing an example of pants. Note that the structure of the overlapping portion of the cuffs and the hem is the same as the structure of the overlapping portion S provided on the upper garment, and a description thereof will be omitted.

As shown in FIG. 1, the right front body a and the right side body b are sewn on the front body of the jacket to form a right stitching line A. Further, the left front body a 'and the left side body b' are sewn to form a left stitching line A '. Further, the right side body b and the left side body b 'and the back body are sewn to form right and left stitching lines B and B'. The breathable wear according to the present invention is not limited to sewing, and various joining methods such as known joining means such as adhesive sewing may be used. Moreover, it is preferable to apply a seam tape along the sewn portions because raindrops can be prevented from entering from these sewn portions.

The left and right front bodies a and a 'are each composed of three cloth pieces 1, 2, 3 and 1', 2 'and 3' divided into upper, middle and lower stages. The left and right side bodies b and b 'are respectively composed of three cloth pieces 4, 5, 6 and 4', 5 ', 6'. The three pieces of cloth divided into the upper, middle, and lower tiers have an overlapping portion S in which the lower portion of the upper tier piece is superposed on the surface of the upper portion of the middle piece. A downward second vent hole is provided at the lower end of each overlapping portion S. In FIG. 1, upper and lower vents 20, 21 and lower vents 20 ', 21' are provided on the left and right front bodies, and upper vents 22, 23 and lower vents 22 ', 23' are provided on the left and right side bodies. ing. In order to prevent a reduction in the ventilation effect due to the stagnation of air convection in the jacket, it is preferable that at least two overlapping portions S are provided at the upper and lower portions.

The overlapping part S provided at two places, the upper part and the lower part, sucks outside air from the lower position of the jacket (lower second vent) and warms and gets wet from the higher position (upper second vent) It has the effect of promoting the venturi effect of exhausting air. Also, the upper second vents 20, 20 'provided in the left and right front bodies a, a' and the second vents 22, 23, 22 'provided in the left and right side bodies b, b' of FIG. , 23 'are inclined with respect to the lateral direction in order to facilitate the discharge of damp air inside the jacket. The position of the second vent is important to ensure an effective and appropriate discharge effect during exercise and work. The shape, position, and size of the second vent are appropriately determined according to the type of wear (outerwear, trousers, coat), the size of the wearer's body, the wearing location, the outside air temperature, and the like.
Reference numeral 35 denotes a lower fastening means for the upper garment. The first vent will be described later with reference to FIG.

Also, the back body c shown in FIG. 2 is composed of three pieces of cloth 7, 8, 9 divided into upper, middle and lower stages, like the front body. Downward second vent holes 24 and 25 are provided in the overlapping portion S in which the lower part of the upper cloth piece 7 divided into the upper, middle and lower stages is overlapped with the surface of the upper part of the lower middle cloth piece 8. ing. Since the moisture tends to accumulate on the upper part of the back of the jacket, it is preferable to provide the overlapping portion near the collar. Further, it is preferable that the length of the overlapping portion S is set to 2 to 8 cm so that the upper cloth piece is pulled and raindrops do not enter from the second vent when the wearer bends forward. If the length of the overlapping portion S is less than 3 cm, raindrops may easily enter when the upper cloth piece is turned by the wind. In addition, when the posture exceeds 3 cm, the upper cloth piece overlaps and adheres to the lower cloth piece, which may cause a problem in air permeability. Reference numeral 36 denotes a hood storage section that is worn on the head in the rain. When riding a bicycle or the like, the hood (not shown) may capture the headwind from the direction of travel and may come off the head. However, if at least one overlapping part is provided on the rear side of the hood, it will be captured by the hood. The outside air is not released from the head by being discharged from the second vent.

Right sleeve d and left outer sleeve 10 'sewn on the right outer sleeve 10 and right inner sleeve 11 with stitching lines C and D, and left sleeve d with the left inner sleeve 11' stitched with stitching lines C 'and D' 'Is front body a, a' and side body b, b 'and further back body c is sewed to form front sleeve stitching lines E, E' and rear sleeve stitching lines F, F '. The overlapping portion S provided on the left and right sleeves d and d 'is provided near the inside of the side where moisture tends to accumulate, that is, on the inner sleeves 11 and 11'. Therefore, the left and right inner sleeves 11, 11 ′ are divided into two upper and lower cloth pieces 12, 13 and the lower part of the upper cloth pieces 12, 12 ′ of 12 ′, 13 ′ and the lower cloth pieces 13, 13 ′. Overlaid on the surface of the upper part of 13 ', a downward second vent hole 26, 26' is provided in the overlapping part S. In the case of a sleeve, the cuff serves as a lower vent, so only one overlapping portion is required. The front sleeve stitching lines E and E ′ and the rear sleeve stitching lines F and F ′ are preferably subjected to piping of retroreflective material in order to ensure safety on a rainy day when the sun goes down early. .

In the trousers, as shown in FIG. 3, the right and left front bodies e and e ′ and the right and left rear bodies f and f ′ of the trousers are stitched together by an inner sewing line G and an outer sewing line H ′. The front bodies e and e 'are each composed of two pieces of cloth 51 and 52 and 51' and 52 'divided into two on the upper and lower stages. In the two pieces of cloth divided into the upper and lower tiers, an overlapping portion S is provided by superimposing the lower part of the upper piece of cloth on the surface of the upper part of the lower piece of cloth. In order to allow outside air to enter from the overlapping portion , the position of the overlapping portion is preferably provided near the knee. An ankle tightening means is provided at the tip of the inner hem mouth to tighten the hem mouth to the ankle to prevent rainwater from entering. Further, a mesh fabric 101 having a width of 1 to 8 cm and usually 2 to 3 cm is attached between the belt core sewing line I of the trousers and the upper cloth 51. The mesh fabric 101 corresponds to the second upper vent. If the width of the mesh fabric 101 exceeds 8 cm, the strength of the trousers is inferior and there is a problem in design. In addition, when the width is less than 1 cm, there is a problem that the mesh fabric is troublesome to attach and the air permeability is poor. In order to reinforce the strength of the mesh fabric, the belt core sewing line I and the upper pants 51 of the trousers are connected by a reinforcing member 102 made of a narrow fabric. When the outerwear is worn, the belt core sewing line I at the top of the trousers is hidden, so there is no problem in appearance even if the mesh fabric 101 is provided near the belt.

FIG. 4 is an explanatory view of the breathable cloth piece of the present invention, and shows the structure of the upper and lower overlapping portions S and S of the breathable cloth piece. Next, the TT cross-sectional structure of the right front body b shown in FIG. 1 will be described with reference to FIG. The lower part of the upper cloth piece 4 constituting the right front body b is overlapped with the upper part of the intermediate corrugated cloth piece 5, the overlapping part S is provided, and the upper second cloth opening downward at the end of the overlapping part S is provided. A vent 20 is provided. A lower portion of the intermediate cloth piece 5 is overlapped with an upper portion of the lower cloth piece 6 to provide an overlapping portion S, and a lower second vent 21 is provided at an end portion of the overlapping portion S. 31 is a mesh fabric provided in the whole inside of air permeable wear. The upper end of the intermediate corrugated cloth piece 5 is folded outward to form a V-shaped weir 40. The length of the folded portion 41 is 1 to 5 cm, usually 2 to 3 cm. If it is less than 1 cm, raindrops stopped by the weir may pass through the weir and enter the inside from the first vent. If it exceeds 5 cm, the folded portion forming the weir may be deformed to form a raindrop passage.
The folding may be a single layer or multiple layers. In the case of a plurality of layers, it is necessary to sew the vicinity of a plurality of folds to be polymerized to integrate the V-shaped weir. In the case of multiple layers, even if the length of the folded portion is short, the entry of wind and rain can be reliably prevented. Further, it is preferable to sandwich and fold back a thick fabric of several mm or the like because the fabric can be prevented from adhering and a V-shaped weir is always formed.

Further, the end portion of the upper step cloth piece 4 and the folded portion 41 of the intermediate step cloth piece 5 are connected by a connecting means 42. The thickness of the connecting means is 2 to 6 mm, usually 3 to 5 mm. As for the connection means 42, the cloth of width 10mm-30mm and thickness 2-6mm is attached to the folding | returning part 41 of the intermediate | middle step cloth piece 5, and the edge part of the upper step cloth piece 4, for example at intervals of 3-12cm. The first vent 103 is formed between the upper cloth piece 4 and the folded portion 41 of the intermediate cloth piece 5 by such connecting means.

Moreover, when using the material which is inferior in breathability, such as a cloth, a mesh-like cloth, and a hook-and-loop fastener, as the connection means 42, the connection means of 2-6 mm in thickness normally, for example, the connection means of 10 mm-30 mm width are 3-12 cm intervals. It is attached. When the thickness is 2 mm or less, the gap forming the first vent 103 is small and the air permeability is insufficient. Moreover, when it exceeds 6 mm, there is a risk that raindrops may enter the interior over the weir in strong winds. When the connecting means 42 made of a thin fabric having a thickness of 2 mm or less and a hook-and-loop fastener is used, the connecting means is folded several times so that the thickness of the connecting means is 2 to 6 mm, and the folded portions are folded between the folded portions 41 and the upper cloth pieces 4. A gap is formed that is attached to the portion to form the first vent. Moreover, when using the fabric excellent in air permeability, for example, a three-dimensional solid fabric, it is preferable to attach to the whole space | interval of the folding | returning part 41 of the edge part of the upper stage cloth piece 4, and the intermediate | middle step cloth piece 5. FIG. The three-dimensional three-dimensional fabric is preferably used with a thickness of usually 2 to 15 mm.
The three-dimensional three-dimensional woven fabric has a possibility that the fibers of the cut surface may be separated and the appearance is also inferior. Therefore, if the three-dimensional three-dimensional woven fabric is wrapped with a mesh fabric or a net-like body, the fibers of the cut surface will not be separated. In addition, the mesh cloth wrapped around the three-dimensional solid fabric is sewn to the end and the folded portion of the upper fabric piece 4, and the end of the net-like body is sewn, so it is easier to sew than the three-dimensional solid fabric, and the finish is clean. is there.

If wear is worn when the weather is strong, the second vents 20 and 21 may expand and raindrops may enter the interior. However, the breathable wear of the present invention is shown in FIGS. 5 and 6 (FIG. 5). As shown in the V portion detailed explanatory diagram), when the second vent 20 is enlarged, the folded portion 41 of the intermediate corrugated cloth piece 5 is pulled by the connecting means 42 to open the V-shaped rainwater intrusion prevention weir 40, Since raindrops are collected in this weir and flow down along the intermediate corrugated piece 5, rainwater can be reliably prevented from entering the wear. Further, when the second vent 20 is enlarged, the gap between the first vent 103 is narrowed by the connecting portion 42 and the amount of air passing through the first vent 103 can be reduced. Can be prevented from cooling.

The connecting member 42 is attached 5 to 15 mm inside from the end of the upper cloth piece 4.
Further, a raindropper 104 of 1 to 10 cm is provided at the end of the upper fabric piece 4. The raindropper 104 makes it easy to cut raindrops flowing down the surface of the upper cloth piece 4. The end portion of the upper cloth piece 4 may be left uncut or may be folded back as shown in FIG. In the case of folding, the end of the connecting member 42 may be connected to the folded portion.

By connecting the folded portion and the end of the upper cloth piece with the connecting means, it is possible to prevent the upper cloth piece 4 from turning up when the wind and rain are strong, but there is a risk that the second vent 22 will be greatly enlarged due to a gust of wind or the like. is there. When the second vent is enlarged, the first vent 103 is also enlarged. In order to prevent the expansion of the first vent 103, as shown in FIG. 7, between the end of the upper fabric piece 4 and the lower fabric piece 5 above the lower end of the overlapping portion, usually 1-5 cm above. connecting means, is connected Then expand the second ventilation opening 22 in, for example narrow fabric 105 can be prevented. Moreover, you may connect by spot sewing or a pin. As the narrow fabric, a piece of fabric having a thickness of 1 to 5 mm and a length of 1 to 5 cm is usually used . The connection interval may be an interval at which the upper cloth piece 4 does not turn up. Usually arranged at least 3 cm apart. If the wearing time of the breathable wear becomes long, the inside of the wear may be sweated and the wearable clothing may adhere to the clothes, but the mesh fabric 31 provided in the entire inside of the breathable wear has a gap between the clothes and the breathable wear. This prevents the clothing from sticking to the clothing due to internal steaming. Further, there is an advantage that the mesh fabric 31 can be worn smoothly when the outerwear is worn.

When using a non-breathable material such as a fabric or a string-like member as the connecting means, it is necessary to arrange them at intervals in order to ensure a ventilation path. On the other hand, when using a three-dimensional solid knitted fabric excellent in air permeability as a connecting means, it arrange | positions on the whole surface without a space | interval. Since the three-dimensional solid knitted fabric is composed of two layers of front and back knitted fabrics and a large number of connecting yarns connecting the two layers of knitted fabric, when a mist-like raindrop passes through the three-dimensional solid knitted fabric, Since it contacts and condenses on many connection thread | yarns, the penetration | invasion of a mist-like raindrop can also be prevented reliably. Specific structures of the three-dimensional solid knitted fabric are described in JP-A-10-102363, JP-A 20002-138352, JP-A 02-74648 and the like.

The three-dimensional solid knitted fabric is usually knitted by a double raschel knitting machine, a double tricot knitting machine, a double circular knitting machine, a flat knitting machine having a V bed, or the like. Non-water-absorbing fibers such as polyester fibers, polyethylene fibers, polypropylene fibers, polyvinyl chloride fibers, and polyvinylidene chloride fibers are used as the yarns constituting the two layers of the front and back layers. The connecting yarn for connecting the two layers of the front and back layers is made of the same fiber as the two layers of the front and back layers, but usually a polyester fiber having an excellent compression recovery rate. Such a three-dimensional solid knitted fabric is manufactured and sold by each fiber manufacturer. For example, Unitika Ltd. “Cubic Eye” (registered trademark), Sumie Textile Co., Ltd. “Swing Net” (registered trademark), Asahi Kasei Fibers Ltd. “Fusion” (registered trademark), Toyobo Co., Ltd. It is sold under a brand name such as “Breath Air” (registered trademark).

Example 1, Example 2 and Comparative Example 1
Next, the effects of the breathable wear of the present invention will be described in Examples 1 and 2 and Comparative Example 1.
A breathable garment having the overlapping portions shown in FIG. 1 and FIG. 2 at two locations on the upper and lower sides and having cuffs as shown in FIG. Further, the same wear as in Example 1 was provided, and the second vent was provided at one place (wear having no lower vent), and the wear having a normal cuff was defined as Example 2.

As a comparative example 1, a commercially available ordinary outerwear jacket was used. A test subject wearing a polyester cotton blend sports shirt on cotton underwear was made to wear the above-mentioned raincoat and was installed in a thermo-hygrostat set at a temperature of 25 ° C., a humidity of 70% and a wind speed of 1 m. 5 minutes rest, 2 minutes walk, 5 minutes rest, 2 minutes walk were repeated with a belt walking exerciser, and changes in temperature and humidity were measured with a temperature / humidity sensor (Thermo Recorder “Ondori RH” TR-72S). The humidity sensor was attached to the underwear of the wearer's back, and the temperature sensor was attached to the back of the sports shirt.
Outerwear jacket used in the test Comparative Example 1 (ordinary commercial raincoat)
Table: Nylon (PVC coating)
Back: Polyester (mesh fabric)
Example 1 and Example 2
Table: Nylon (PVC coating)
Back: Polyester (mesh fabric)

The test result discomfort index was calculated from the humidity measured with the humidity sensor affixed on the underwear of the wearer's back and the temperature measured with the temperature sensor affixed on the back of the sports shirt by the following equation.
Discomfort index = 0.81T + 0.01U (0.99T-14.3) +46.3
T: Temperature (° C) U: Humidity (%)
The result of calculating the discomfort index from the temperature and humidity in Comparative Example 1, Example 1 and Example 2 is shown in FIG. As is clear from FIG. 20, the discomfort index of the outside air at the time of the test was 74. In Comparative Example 1, the discomfort index is 93 or more, but “unbearable”, but in Example 1, the discomfort index is 78 or more and “slightly hot”. In Example 2, the discomfort index was 84 or more and “slightly discomfort” was alleviated. There is a clear difference between Examples 1 and 2 and Comparative Example 1, and the breathable wear according to the present invention, particularly the breathable wear used in Example 1 in which the overlapping portions S are provided in two places above and below, depends on the body temperature. It is clear that the generated heat and moisture are efficiently discharged to the outside.

Example 3 and Comparative Example 2
Next, the discomfort index was calculated from the temperature and humidity of the air-permeable wear of the present invention (Example 3) used in Example 1 and the wear shown in FIG. 1 without a connecting member (Comparative Example 2) under strong wind. The calculated results are shown in FIG. A test subject wearing a polyester cotton blend sports shirt on cotton underwear is allowed to wear the above-mentioned wear in a thermo-hygrostat, making the thermo-hygrostat in a strong wind state with a wind speed of 30 m, and further dripping water Let it be in a state of severe wind and rain. Next, the subject exercised in the thermo-hygrostat.

In Example 3, even when wind and raindrops enter from the second vent, the V-shaped rainwater intrusion prevention weir prevents entry of raindrops and enters the interior of the wear from the first vent. There were no raindrops. Moreover, the subject's body was not cooled by the strong wind because the gap forming the first vent was narrowed or the amount of ventilation entering the inside through the first vent was reduced. The discomfort index also relieved with “slightly discomfort” over 85. Moreover, there was little increase in humidity in the exercise state, and it did not reach an area where it was completely uncomfortable. On the other hand, in Comparative Example 2, since the V-shaped rainwater intrusion prevention weir did not expand, raindrops entered the wear immediately after the start of gymnastics. In addition, since the gap between the first vents was wide, the strong wind entered the inside as it was, and the subject's body was cooled rapidly.
Moreover, since the humidity increased rapidly, the discomfort index of 90 or more, which was considered completely unpleasant, was reached 5 minutes after the start of gymnastics.
