Description

  The present invention relates to a hat excellent in breathability.

  It is recommended that you wear a hat during outdoor activities during the day when the sunlight is strong, as it can cause sunstroke if you hit the head for a long time. However, many people shy away from hats because they often feel uncomfortable when they wear hats during the hot summer months. In particular, a hat having a crown formed of a water repellent or waterproof fabric is difficult to ensure air permeability, and thus has a strong tendency. In view of such a situation, hat manufacturers have come to apply various ideas to the hat to improve the air permeability.

  For example, a hat in which a part of a crown is formed of a mesh sheet has been proposed (see, for example, Patent Document 1). However, in this type of cap, although air permeability in the portion formed by the mesh sheet in the crown is ensured, air permeability in other portions in the crown is not ensured. For this reason, in order to secure sufficient air permeability with this type of hat, it was necessary to increase the area of the portion formed by the mesh sheet in the crown. And the hat design was severely limited.

  In view of such a situation, until now, the outside of the portion of the crown formed by the mesh sheet (the ventilation portion) is covered with a cover, and the ventilation portion is opened by folding or removing the cover. Hats that can be closed have also been proposed (see, for example, Patent Documents 2 to 5). This type of hat can change the ventilation state of the crown, so it can be worn regardless of the weather or season.

  However, even in this type of hat, if the air permeability is to be ensured, the cover must be folded back, and the light-shielding property of the hat is not sacrificed. Further, when the cover is folded, there is a possibility that the appearance when worn is deteriorated, for example, an unsightly wrinkle is formed on the crown.

  The present invention has been made to solve the above-described problems, and provides a cap that can improve the breathability of the crown while maintaining the light shielding performance of the crown. It is also an object of the present invention to provide a hat that can ensure breathability without any special modification and that does not cause unsightly wrinkles on the crown. It is another object of the present invention to provide a hat with a high degree of design freedom.

The above issues
A left-side ventilation opening having an elongated shape with a length of 10 to 20 cm and a maximum width of 0.5 to 5 cm provided from the lower edge of the left front side of the crown made of a light-shielding material to the upper side or obliquely rearward; A hat provided with a right vent opening having an elongated shape having a length of 10 to 20 cm and a maximum width of 0.5 to 5 cm provided from the lower edge of the side toward the upper side or obliquely rearward ;
The portion for the left vent opening is provided in the rear surface of the crown I is addressed to the left mesh sheet, along with extending the left mesh sheet to a portion forming a left rear portion of the crown at the rear surface of the crown, left By sewing the front edge, the rear edge and the lower edge of the mesh sheet to the crown, a left ventilation space is formed in the gap between the crown and the left mesh sheet ,
The right mesh sheet is directed to the portion provided with the right ventilation opening on the back surface of the crown, and the right mesh sheet is extended to the portion forming the right rear portion of the crown on the back surface of the crown, and the right side. By sewing the front edge, rear edge and lower edge of the mesh sheet to the crown, a right ventilation space is formed in the gap between the crown and the right mesh sheet,
The ratio S ₁ / S ₂ of the area S ₁ of the left mesh sheet and the opening area S ₂ of the left ventilation opening , and the ratio S of the area S ₁ ′ of the right mesh sheet and the opening area S ₂ ′ of the right ventilation opening both the ₁ '/ _{S 2'} and 2 to 20,
A hat characterized in that outside air introduced into the crown from the left vent opening and the right vent opening can be spread over a wide area inside the crown through the left vent space and the right vent space , respectively. Solved by providing.

As a result, the area of the ventilation openings (the left ventilation opening and the right ventilation opening) is narrowed to ensure sufficient light shielding of the hat, while allowing outside air to be taken into a wide area inside the crown. Therefore, it is possible to provide a hat that can be efficiently ventilated inside and outside the crown. In addition, it is easy to ensure sufficient air permeability while narrowing the left vent opening and right vent opening. It is also possible to provide a hat with a high degree.

The ratio S ₁ / S ₂ of the area S ₁ of the left mesh sheet and the opening area S ₂ of the left ventilation opening , and the ratio S of the area S ₁ ′ of the right mesh sheet and the opening area S ₂ ′ of the right ventilation opening ₁ ′ / S ₂ ′ is set in the range of 2 to 20 for all. However, if the ratio S ₁ / S ₂ and the ratio S ₁ ′ / S ₂ ′ are too small, the left ventilation space and the right ventilation space become narrow, and it becomes difficult to spread outside air over a wide range inside the crown. There is a fear. Therefore, the ratio S ₁ / _{S 2} and the ratio _{S 1} '/ _{S 2'} is preferable to be 3 or more, more preferably 4 or more and further preferably 5 or more.

On the other hand, the ratio S ₁ / S ₂ of the area S ₁ of the left mesh sheet and the opening area S ₂ of the left ventilation opening , and the area S ₁ ′ of the right mesh sheet and the opening area S ₂ ′ of the right ventilation opening If the ratio S ₁ ′ / S ₂ ′ is too large, wasteful portions that do not substantially contribute to ventilation are likely to occur in the left ventilation space and the right ventilation space , which is inefficient. Therefore, the ratio S ₁ / _{S 2} and the ratio _{S 1} '/ _{S 2'} is preferable to be 17 or less, more preferable to be 15 or less, further preferably 13 or less.

In the hat of the present invention, the left ventilation opening and the right ventilation opening are each formed in an elongated shape having a length of 10 to 20 cm and a maximum width of 0.5 to 5 cm . As a result, it is possible to make the hat have both air permeability and design.

Further, in the hat of the present invention, together with is respectively located left side and the lower edge of the right front side of the front than the front-rear direction intermediate position of the crown of the forwardmost portion for the left vent opening and for the right vent opening, left vent The left mesh sheet addressed to the opening for the right side and the right mesh sheet addressed to the opening for the right side ventilation are respectively located behind the rear end of the left side ventilation opening and the right side ventilation opening and in the middle of the crown in the front-rear direction. It extends to the portion forming the left rear portion of the crown behind the position and the portion forming the right rear portion of the crown . Thereby, it becomes possible to take in the outside air smoothly from the front of the crown and spread the outside air over a wide range from the inside of the crown to the rear. This configuration is preferably used in an exercise cap such as a baseball cap, where the wearer often walks or runs forward.

More specifically, the left of the crown to the left mesh sheet destined to crack for the left vent opening in the rear surface of the crown having an elongated shape provided upward or obliquely rearward from the left front side of the lower edge of the click lounger It extended to the part forming the rear section Rutotomoni crown right mesh sheet destined to crack into the opening for the right vent having from the lower edge of the right front side of the crown elongate shape provided upward or obliquely rearward the Rukoto extend in the back surface to a portion forming a right rear portion of the crown, the left ventilation space to the left of the crown, to form respectively a right ventilation space on the right side of the crown. As a result, outside air can be equally taken into a wide range on the left and right sides inside the crown.

  At this time, it is preferable to form each of the left vent opening and the right vent opening having an elongated shape so that the width becomes narrower as the position becomes higher from the lower edge of the crown. As a result, the shape of the left vent opening and the right vent opening gives a sharp impression, not only makes the hat look good, but also has a large surface area and requires a large amount of outside air to be taken in. It is also possible to take in outside air efficiently.

  As described above, according to the present invention, the present invention can provide a cap capable of improving the breathability of the crown while maintaining the light shielding performance of the crown. In addition, it is possible to provide a hat that can ensure air permeability without any special modification and does not cause unsightly wrinkles on the crown. It is also possible to provide a hat with a high degree of freedom in design.

1. Outline of Hat As shown in FIGS. 1 to 3, the hat according to this embodiment is provided with a left ventilation opening O ₁ and a right ventilation opening O _{2 in a} crown 10 made of a light shielding material. . As shown in FIG. 6, a portion (a portion surrounded by point A ₁ , point A _2, and point A ₃ ) provided with a left ventilation opening O ₁ on the back surface of the crown 10, and a right ventilation opening. The mesh sheets 20 are respectively assigned to the portions where O ₂ is provided (portions surrounded by the points B ₁ , B _2, and B ₃ ). Of the mesh sheet 20, the left mesh sheet 21 is not only the portion provided with the left vent opening O ₁ on the back surface of the crown 10, but also the portion where the left vent opening O ₁ is not provided (point A _1). And the point A ₃ , the point A _4, and the point A ₅ . In addition, the right mesh sheet 22 is not only the portion provided with the right ventilation opening O ₂ on the back surface of the crown 10 but also the portion where the right ventilation opening O ₂ is not provided (the points B ₁ and B _3. It is extended to the portion), which is surrounded by the preparative point B ₄ and point B _5. Gaps are formed between the inner surface of the crown 10 and the outer surface of the left mesh sheet 21, and between the inner surface of the crown 10 and the outer surface of the right mesh sheet 22, and the gap functions as a ventilation space. Can be done. That is, outside air introduced into the crown 10 from the left ventilation opening O ₁ and the right ventilation opening O ₂ is spread over a wide range inside the crown 10 through the gap (venting space) (thickness in FIG. 6). Arrow), and the head of the wearer can be effectively cooled.

  The type of the hat of the present invention is not particularly limited as long as the cap has a crown 10. Specifically, a cap-type cap with a heel attached to the front side of the lower edge of the crown 10, a hat-type cap with a heel attached to the entire periphery of the lower edge of the crown 10, An example of a hat without a heel is not attached. Among these, a cap-type cap is preferable. This is because a cap-type hat is often used as an athletic cap or a work cap, and is often worn in a hot place, so that it is significant to maintain good air permeability. As shown in FIG. 1, the cap of this embodiment includes a crown 10 for covering the wearer's head, and a cap provided with a collar provided to project forward from the front peripheral portion at the lower edge of the crown 10. It is of a type.

The number of crown lashes forming the crown 10 is not particularly limited. However, in the cap of this embodiment, the crown lash 11a forming the left front portion of the crown 10 and the crown ridge forming the left lateral portion of the crown 10 are used. The crown 11b, the crown spatula 11c forming the left rear portion of the crown 10, the crown spatula 12a forming the right front portion of the crown 10, the crown spatula 12b forming the right lateral portion of the crown 10, and the crown 10 6 pieces with the crown spatula 12c forming the right rear portion of

As shown in FIG. 4, the crown spatula 11a and the crown spatula 12a, the crown spatula 11b and the crown spatula 11c, the crown spatula 12b and the crown spatula 12c, and the crown spatula 11c and the crown spatula 12c, These side edges are sewn together through strips 40a, 40b, 40c, and 40d. On the other hand, the crown spatula 11a and the crown spatula 11b, and the crown spatula 12a and the crown spatula 12b are not sewn at their side edges, and the crown spatula 11a and the crown spatula 11b are not sewn together. , and between the crown for lotus 12a and the crown for Renge 12b, gaps respectively on the left side ventilation openings O ₁ and the right ventilation opening O ₂ is formed.

The left ventilation opening O ₁ (the portion surrounded by the points A ₁ , A _2, and A ₃ ) is an elongated isosceles triangular shape provided upward from the lower left edge of the crown 10. The vertex (point A ₁ ) reaches the vicinity of the vertex of the crown 10. The foremost portion (point A ₂ ) of the left-side ventilation opening O ₁ is disposed in front of the intermediate position in the front-rear direction of the crown 10. On the other hand, the right-side ventilation opening O ₂ (the portion surrounded by the points B ₁ , B _2, and B ₃ ) is an elongated isosceles side that is provided upward from the lower edge on the right front side of the crown 10. It has a triangular shape, and its apex (point B ₁ ) reaches near the apex of the crown 10. The foremost portion (point B ₂ ) of the right-side ventilation opening O ₂ is disposed in front of the intermediate position in the front-rear direction of the crown 10. As described above, the front portions of the left vent opening O ₁ and the right vent opening O ₂ are arranged in front of the intermediate position in the front-rear direction of the crown 10, thereby efficiently taking in outside air from the front of the crown 10. It becomes possible.

The opening areas of the left vent opening O ₁ and the right vent opening O ₂ are not particularly limited as long as each is 1 cm ² or more. However, if the opening area is too narrow, it may be difficult to take in the outside air sufficiently into the crown 10. is there. For this reason, the opening areas of the left vent opening O ₁ and the right vent opening O ₂ are usually 3 cm ² or more, respectively. Opening area of the left side ventilation openings _{O 1} and the right ventilation opening _{O 2} is preferable to be respectively 5 cm ² or more, and more preferably each 7 cm ² or more. On the other hand, an excessively wide opening area of the left side ventilation openings O ₁ and the right ventilation opening O _2, not only light-shielding cap is lowered, appearance of hats is poor contact it also. For this reason, the opening areas of the left vent opening O ₁ and the right vent opening O ₂ are normally 50 cm ² or less, respectively. Opening area of the left side ventilation openings _{O 1} and the right ventilation opening _{O 2} is preferable to be 40 cm ² or less, and more preferably a 30 cm ² or less, respectively. In the hat of this embodiment, the left ventilation opening O ₁ and the right ventilation opening O ₂ are both substantially isosceles triangles having a bottom of less than 3 cm and a height of about 17 cm, and the respective opening areas are as follows. Is approximately 25 cm ² .

The rear edge (the edge along the line A ₁ A ₂ in FIG. 4) of the crown spatula 11a is sewn to the front edge of the left mesh sheet 21 via the strip 42a (FIG. 6). The rear edge of the crown spatula 12a (the edge along the line segment B ₁ B ₂ in FIG. 4) is connected to the front edge of the right mesh sheet 22 via the strip 42b (FIG. 6). Sewn. On the other hand, the front edge (the edge along the line segment A ₁ A ₃ in FIG. 4) of the crown spatula 11b and the front edge (the line B ₁ B ₃ in FIG. 4) of the crown spatula 12b. The edge) is not sewn to the mesh sheets 21 and 22 and is in a state of floating from the mesh sheets 21 and 22.

  The material of the crown 10 is not particularly limited, but in the cap of the present embodiment, each of the crown spaws 11a, 11b, 11c, 12a, 12b, and 12c is formed on the outer surface (reference numeral omitted) that forms the outermost surface of the crown 10. And a lining (not shown) having no water permeability. On the outer surface of the crown spaws 11a, 11b, 11c, 12a, 12b, 12c, waterproof processing (for example, processing for closing the gap between the fibers forming the outer surface with a waterproof material such as fluorine resin or silicon resin) Water repellent processing (for example, processing in which a surface material is impregnated with a water repellent material such as a fluorine-based resin or a silicon resin, or each fiber forming the surface material is coated with the water repellent material). It is also preferable. As described above, the hat having a waterproof or water repellent finish on the crown 10 is difficult for rainwater or the like to soak into the interior, but the air permeability is sacrificed. Significantly improving air permeability.

  Further, of the crown spaws 11a, 11b, 11c, 12a, 12b, and 12c, on the further back side (inside) of the lining of the two front crown spaws 11a and 12a, the crown spaws 11a and 12a are substantially the same. The cloth (symbol omitted) having the same shape-retaining property is provided. This shape-retaining fabric has a function similar to that of a placket in a conventional hat, and contributes to maintaining the overall shape of the crown 10 in a substantially dome shape.

3. Mesh Sheet In the hat of the present embodiment, as shown in FIG. 5, the mesh sheet 20 is composed of a plurality of mesh sheet spades 21 a, 21 b, 22 a, and 22 b having a substantially isosceles triangle shape. Among the mesh sheets 20, the left mesh sheet 21 is composed of a mesh sheet leash 21 a that forms the left side portion of the mesh sheet 20 and a mesh sheet leash 21 b that forms the left rear portion of the mesh sheet 20. . On the other hand, the right mesh sheet 22 includes a mesh sheet spatula 22 a that forms the right side portion of the mesh sheet 20 and a mesh sheet spatula 22 b that forms the right rear part of the mesh sheet 20.

  As shown in FIG. 5, the mesh sheet spatula 21 a and the mesh sheet spatula 21 b, the mesh sheet spatula 22 a and the mesh sheet spatula 22 b, and the mesh sheet spatula 21 b and the mesh sheet spatula 22 b Are sewn together through strips 41a, 41b, 41c. Of these, the strips 41 a and 41 b are not sewn to the crown 10 (FIG. 4) and are in a state of floating from the crown 10. On the other hand, the band piece 41 c is sewn to the band piece 40 d in the crown 10. This is because the left ventilation space formed in the gap between the inner surface of the crown 10 and the outer surface of the left mesh sheet 21 and the right ventilation space formed in the gap between the inner surface of the crown 10 and the outer surface of the right mesh sheet 22. However, it is preferable not to sew the band piece 41c to the crown 10. In this case, the mesh sheet 20 may easily hang down inside the crown 10. The lower edges of the mesh sheet forges 21a, 21b, 22a, 22b are sewn to the lower edges of the crown forges 11b, 11c, 12b, 12c (FIG. 4), respectively.

The areas of the left mesh sheet 21 and the right mesh sheet 22 are not particularly limited as long as they are wider than the left ventilation opening O ₁ and the right ventilation opening O ₂ , respectively. It may be difficult to take in outside air. For this reason, the areas of the left mesh sheet 21 and the right mesh sheet 22 are normally set to 100 cm ² or more, respectively. Area of the left mesh sheet 21 and the right mesh sheet 22 is preferable to be 150 cm ² or more, respectively, and more preferably a 200 cm ² or more. On the other hand, if the areas of the left mesh sheet 21 and the right mesh sheet 22 are too large, a wasteful portion that does not substantially contribute to ventilation is likely to be generated in the ventilation space, which is inefficient. For this reason, the areas of the left mesh sheet 21 and the right mesh sheet 22 are usually set to 450 cm ² or less, respectively. Area of the left mesh sheet 21 and the right mesh sheet 22 is preferable to be 400 cm ² or less, and more preferably a 350 cm ² or less. In the hat of the present embodiment, the left mesh sheet 21 and the right mesh sheet 22 each have a radius of about 17 cm and a center angle of about 120 so as to cover substantially the entire back surface of the crown spars 11b, 11c, 12b, and 12c. The area is approximately 280 cm ² (excluding the rear notch for providing the size adjusting belt 50 (FIG. 7)). Therefore, the area of the right mesh sheet 22 to form a ratio _S 2 / _{S 1,} and right ventilation space area _{S 1} and the left vent opening _{O 1} of the opening area _{S 2} of the left mesh sheet 21 to form the left ventilation space S ₁ 'and the opening area _{S 2} of the right ventilation openings _{O 2'} ratio _{S 2} '/ _{S 1'} of both is about 11.

The material of the mesh sheet 20 is not particularly limited as long as it has a breathable mesh shape, and various fabrics such as a knitted fabric and a woven fabric can be used. Especially, since the knitted fabric has characteristics such as excellent air permeability, hardly wrinkles, and high productivity, it can be suitably used as a material for the mesh fabric 20. The air permeability of the mesh sheet 20 (the air permeability measured by the A method (Fragile method) described in 8.27.1 in JIS L 1096) is not particularly limited. However, if the air permeability of the mesh sheet 20 is too low, it becomes difficult to keep the air permeability of the hat 10 good, and the wearer's head may be easily stuffy. For this reason, the air permeability of the mesh sheet 20 is normally set to 100 cm ³ / cm ² · s or more. The air permeability of the mesh sheet 20 is preferably 150 cm ³ / cm ² · s or more, and more preferably 200 cm ³ / cm ² · s or more.

4). Bin Skin In the hat according to this embodiment, as shown in FIG. 7, the bottle skin 60 is provided on the back side of the portion along the lower edge of the crown 10, and the sweat of the wearer's head can be absorbed. I am doing so. The material of the bottle skin 60 is not particularly limited, but it is preferable to select a material excellent in water absorption and quick drying.

5. Size Adjustment Band In the hat of the present embodiment, the rear portion of the lower edge of the crown 10 is notched as shown in FIG. 7, and the size adjustment belt 50 is attached to the notched portion. ing. For this reason, the hat can adjust the circumference of the lower edge of the crown 10 according to the size of the wearer's head by adjusting the length of the size adjusting belt 50. .

6). Other Embodiments In the above, the elongated left-side ventilation opening O ₁ is provided upward from the lower left edge of the crown 10, and the elongated right-side ventilation opening O ₂ is provided on the crown 10. there has been described a case where the lower edge of the right front side is provided upward in the form left vent openings O ₁ and right ventilation openings O _2, without departing from the spirit of the present invention, it is modified as appropriate Can do. For example, as shown in FIGS. 8 and 9, an elongated left-side ventilation opening O ₁ is provided obliquely rearward from the lower left front edge of the crown 10, and the elongated right-side ventilation opening O ₂ is formed. It is also preferable that the crown 10 is provided obliquely rearward from the lower edge on the right front side. FIG. 8 is a side view of a hat according to another embodiment of the present invention. FIG. 9 is a view of a hat according to another embodiment of the present invention as viewed from below.

Thus, even while positioned in front of the the foremost part C _1, D ₁ on the left side ventilation openings O ₁ and the right ventilation opening O ₂ front-rear direction intermediate position of the crown 10, for the left vent opening O ₁ And the rearmost tails C ₂ and D ₂ of the right-side ventilation opening O ₂ can be positioned behind the intermediate position of the crown 10 in the front-rear direction. Therefore, outside air can be taken into the interior of the crown 10 from the rear of the crown 10 to ventilate the back of the head more efficiently. However, forward of the front-rear direction intermediate position of the crown 10 in the left side ventilation openings O ₁ and the right ventilation opening O ₂ is being widely formed since it is necessary to take a lot of fresh air, opening for the left vent The rear portion of the portion O ₁ and the right vent opening portion O _{2 with} respect to the center position in the front-rear direction of the crown 10 is formed narrow so that it is not necessary to take in a large amount of outside air. This not only allows for more efficient ventilation, but also makes the hat look better.
