Technical Field

[0001] The present invention relates to a hat.

Background Art

[0002] Conventionally, hats have been widely used as a means to protect the head from sunlight, wind, rain, etc., and also as part of fashion. Hats mainly have a crown that covers the head and a brim, and thus have a structure that combines practicality and decorativeness. On the other hand, in summer or in a high-temperature environment, since heat tends to be trapped inside the hat, ensuring breathability has been emphasized.

[0003] In existing technologies, configurations using mesh fabrics as the material of the hat or configurations providing small holes in the crown have been adopted, and by this, it has been possible to improve the comfort of the wearer.

[0004] In recent years, in order to achieve both design and functionality, various ideas have been applied to the shape and structure of hats. For example, technologies have been proposed in which ventilation holes are integrated into the crown of the hat to discharge the internal air to the outside.

[0005] In Patent Document 1, a hat provided with an air inlet and an air outlet is disclosed for the purpose of improving breathability. Specifically, this hat has a plurality of air inlets, and the air outlet is provided near the top.

[0023] <Basic configuration> This disclosure provides a hat X as an embodiment. Hat X is illustrative to illustrate the technical idea of ​​the present invention and does not limit the scope of the technical idea of ​​the present invention. Furthermore, the components of hat X, as well as the materials, shapes, dimensions, number, and arrangement of the components, can be modified within the scope of the technical idea of ​​the present invention.

[0024] Hat X is a head covering capable of covering the wearer's head, and is not subject to any particular limitations regarding its type, structure, material, dimensions, finish, etc., and encompasses all types of hats that can be worn on the head.

[0025] Hat X may be a cap, hat, helmet cover, sun visor, beret, hood, turban, headband, or any other type.

[0026] Hat X may or may not have a brim (visor), ribbon, strap, pad, decorative elements, or other additional elements as needed.

[0027] Hat X may or may not have a head circumference adjustment mechanism.

[0028] The manufacturing method for hat X may include cutting and sewing, molding, knitting, injection molding, bonding, lamination, three-dimensional molding (3D printing), or any other method.

[0029] Each component of the hat X may or may not be treated with functional finishes such as water repellency, oil repellency, stain resistance, flame retardancy, antistatic properties, antibacterial properties, odor control, UV protection, phosphorescence, coloring, or pattern printing.

[0030] Below, the front-to-back, up-and-down, and left-to-right directions of hat X are defined based on the wearer of hat X.

[0031] Hat X has a crown 1.

[0032] Crown 1 is a covering that covers the wearer's head, and is not subject to any particular limitations regarding its type, structure, material, dimensions, finish, etc., and encompasses any form that can be worn on the head.

[0033] The shape of Crown 1 may be hemispherical, ellipsoidal, conical, cylindrical, three-dimensionally folded, composite, or any other external shape.

[0034] The structure of Crown 1 may be a single-layer structure or a multi-layer structure, a single member or a structure of sutures or adhesives of multiple members, and may or may not contain core materials, reinforcing materials, cushioning materials, shape-retaining materials, etc. as needed.

[0035] The materials that make up Crown 1 can be arbitrarily selected from natural fibers, synthetic fibers, blended fibers, nonwoven fabrics, mesh, leather, plastics, foams, metal wires, and other known materials.

[0036] The dimensions of Crown 1 can be those of an adult, child, or infant.

[0037] The crown 1 has a ventilation section 11.

[0038] The ventilation section 11 refers to all structures or components that connect the inside and outside of the crown 1, and is not subject to any particular limitations regarding its type, arrangement, structure, material, dimensions, finish, etc., and encompasses all ventilation means.

[0039] The shape of the ventilation section 11 may be a mesh, a round hole, an elongated hole, a slit, a grid hole, a composite hole, or any other external shape.

[0040] The arrangement of the ventilation section 11 can be arbitrary, such as on the sides, front, rear, top, entire surface, or a part or multiple locations in the circumferential direction of the crown 1, and may be continuous or discontinuous, and may be distributed in a single location or multiple locations.

[0041] The ventilation section 11 may be formed by perforating, punching, or forming a mesh pattern on the crown 1, or it may be formed by attaching a mesh material, punched sheet, nonwoven fabric, mesh molded body, valved film, etc., which are separate from the crown 1.

[0042] The dimensions of the ventilation section 11 (opening area, hole diameter, number of holes, density, etc.) can be arbitrarily set according to the wearer's comfort, strength, aesthetics, light-blocking properties, waterproofing properties, and other necessary conditions.

[0043] The hat X is equipped with an air intake portion 2 that forms a pocket a on the outer surface of the crown 1.

[0044] The air intake section 2 is positioned so that the opening a1 of pocket a faces forward. This allows the air intake section 2 to take in air from the front when the wearer moves forward, when an airflow is generated from the front, etc.

[0045] The pocket a is preferably formed so that its rear is closed (i.e., it is preferable that it does not have two or more openings a1), but it may be formed so that its rear is open (i.e., it may have an opening a1 facing rear).

[0046] The air intake section 2 is provided such that the internal space a2 of pocket a is approximately parallel to the front-to-back direction of the hat. This allows the air intake section 2 to suppress a decrease in the flow velocity of the air it takes in.

[0047] The air intake section 2 is provided so as to cover at least a portion of the ventilation section 11 from the outside. This allows the air intake section 2 to supply the air it takes in from the ventilation section 11 into the interior of the crown 1.

[0048] With the above configuration, hat X can efficiently supply air from the front into the interior of crown 1, thus exhibiting superior breathability compared to conventional technology.

[0049] Furthermore, even in the event of strong winds from the front, hat X is designed to efficiently release wind into the crown 1, making it less likely to detach from the wearer.

[0050] The air intake section 2 is preferably formed such that the internal space of pocket a narrows continuously or gradually from the front to the rear, i.e., it is a Venturi structure. This allows the air intake section 2 to further suppress the decrease in the flow velocity of the intake air, and in fact increase the flow velocity.

[0051] It is preferable that the air intake section 2 is provided such that, in a front projection view, the projected area of ​​the opening a1 of pocket a (total projected area if there are multiple air intake sections 2) is 5% or more (particularly 10% or more, 15% or more, or 20% or more) of the projected area of ​​crown 1. This allows the air intake section 2 to take in even more air from the front.

[0052] The air intake section 2 is preferably located on the outer edge of the crown 1 in a front projection view. In particular, the air intake section 2 is preferably located on the side and / or top of the crown 1. This allows the air intake section 2 to take in sufficient air from the front, regardless of the shape of the crown 1.

[0053] The air intake section 2 is preferably made of a non-transparent material. This allows the air intake section 2 to add light-shielding properties to the ventilation section 11 that the ventilation section 11 cannot inherently exhibit.

[0054] The cap X includes a flow guide section 3 that forms a wall b on the outer surface of the crown 1.

[0055] The flow guide section 3 is positioned such that its wall b extends forward from the upper and / or lower edge of the air intake section 2. This allows the flow guide section 3 to guide at least a portion of the air coming from the front toward the crown 1 into the air intake section 2.

[0056] The shape of wall b may be flat, curved, bent, wedge-shaped, stepped, composite curved, or any other desired external shape. Furthermore, the dimensions of wall b, such as height, width, inclination angle, and radius of curvature, can be arbitrarily set according to the desired amount of airflow control.

[0057] The flow guide section 3 may be located at any position on the front, side, or outer edge of the crown 1. Furthermore, the flow guide section 3 may be formed as a single wall structure, or as a plurality of continuous or discontinuous wall structures.

[0058] The structure of the flow guide section 3 may be integrated with the crown 1 or the air intake section 2, or it may be a separate structure.

[0059] The flow guide section 3 defines an effective flow guide region c on the outer surface of the crown 1. The effective flow guide region c is treated as an area where air arriving from the front is likely to be subsequently taken into the air intake section 2.

[0060] For example, the effective flow guidance region c can be defined as a region that, in a forward projection view, includes wall b and the lower edge of the opening a1 of pocket a, and is closed by the shortest path. Here, "a region that can be closed by the shortest path" means a region that, in a forward projection view, can be closed by drawing a straight line connecting the endpoint of the upper wall b to the endpoint of the lower wall b, or the endpoint of wall b to the endpoint of the lower edge of the opening a1 of pocket a, when the region cannot be closed by wall b and the lower edge of the opening a1 of pocket a.

[0061] It is preferable that the air intake section 2 and the flow guide section 3 are provided such that, in a forward projection view, the sum of the projected area of ​​the opening a1 of pocket a (total projected area if there are multiple air intake sections 2) and the projected area of ​​the effective flow guide region c (total projected area if there are multiple air intake sections 2) is 20% or more (especially 30% or more, 40% or more, or 50% or more) of the projected area of ​​crown 1.

[0062] Furthermore, by creating a gap between hat X and the wearer's head, hat X allows the air taken in to circulate throughout the wearer's entire head.

[0063] <First example> The first example of hat X is shown in Figures 1-4. This example does not limit the scope of the technical concept of hat X.

[0064] In this example, the hat X is a cap, and the crown 1 and air intake part 2 are made of synthetic fibers.

[0065] The ventilation section 11 (grille surface in the figure) is provided on the left and right sides of the outer surface of the crown 1, extending in the front-to-back direction.

[0066] The crown 1 has a light-shielding section 12 that extends in the front-to-back direction to connect the left and right ventilation sections 11.

[0067] The light-shielding portion 12 is made of a non-transparent material.

[0068] The air intake sections 2 are provided, one on the left and one on the right side of the outer edge of the crown 1 in a front projection view. Furthermore, the air intake sections 2 are provided so as to cover a portion of the ventilation section 11, and so as to have their upper edges aligned with the left or right edge of the light-shielding section 12.

[0069] The air intake section 2 is positioned such that, in a forward projection view, the projected area of ​​the opening a1 of pocket a is approximately 10% of the projected area of ​​crown 1.

[0070] The flow guide section 3 is provided as the boundary between the ventilation section 11 and the light-shielding section 12. That is, the joint between the ventilation section 11 and the light-shielding section 12 functions as a wall b. As a result, the effective flow guide region c (black transparent surface in the figure) is formed in a roughly triangular shape in a forward projection view, and a pair of them are arranged on the left and right sides.

[0071] The air intake section 2 and the flow guide section 3 are arranged such that, in a forward projection view, the sum of the total projected area of ​​the opening a1 of pocket a and the total projected area of ​​the effective flow guide region c is approximately 50% of the projected area of ​​the crown 1.

[0072] To demonstrate the breathability of hat X in this example, a comparative experiment was conducted to measure temperature changes near hat X. Existing hats that boast excellent breathability were used as comparative examples 1 and 2.

[0073] This experiment involved placing each hat outdoors and blowing air from the front using a fan for 3 minutes. The temperatures of the front, top, and back of the hats before and after the airflow were recorded along with the outdoor temperature. The hat temperatures were measured using a laser thermometer.

[0074] The experimental results are shown in Table 1.

[0075] [Table 1]

[0076] The experimental results for hat X show that, compared to the experimental results for comparative examples 1 and 2, the temperature of each part after airflow is lower than before airflow, and the temperature of each part after airflow is lower than the outdoor temperature.

[0077] In this experiment, hat X was able to efficiently supply air from the front into the interior of the crown 1, which is considered to have resulted in superior breathability compared to comparative examples 1 and 2.

[0078] <Second example> A second example of hat X is shown in Figures 5-6. This example does not limit the scope of the technical concept of hat X.

[0079] This example is related to the first example, but differs in that hat X is a hat.

[0080] <Third example> A third example of hat X is shown in Figures 7-8. This example does not limit the scope of the technical concept of hat X.

[0081] This example is related to the first example, but differs in several respects regarding the air intake section 2 and the flow guide section 3.

[0082] The ventilation section 11 is provided along the entire circumference of the sides and the rear of the top of the outer surface of the crown 1.

[0083] The light-shielding section 12 is provided in front of the top of the crown 1 so as to connect to the ventilation section 11.

[0084] In a front projection view, the air intake sections 2 are located one each on the left and right sides of the outer edge of the crown 1, and one additional section at the top. In other words, the air intake sections 2 are also located behind the top of the crown 1.

[0085] The flow guide section 3 is provided as the boundary between the ventilation section 11 and the light-shielding section 12. That is, the joint between the ventilation section 11 and the light-shielding section 12 functions as a wall b. As a result, the effective flow guide region c is formed in a roughly trapezoidal shape in a forward projection view, with one section located in the center.

[0086] The air intake section 2 and the flow guide section 3 are arranged such that, in a forward projection view, the sum of the total projected area of ​​the opening a1 of pocket a and the total projected area of ​​the effective flow guide region c is approximately 100% of the projected area of ​​the crown 1.

[0087] <Fourth example> A fourth example of hat X is shown in Figures 9-10. This example does not limit the scope of the technical concept of hat X.

[0088] This example is related to the first example, but there are some differences regarding hat X.

[0089] The ventilation section 11 is provided on the left and right sides and the rear of the top of the outer surface of the crown 1, extending in the front-to-back direction.

[0090] The Crown 1 has an exhaust section 13.

[0091] The exhaust section 13 refers to the entire structure or component at the rear of the Crown 1 that connects the inside and outside of the Crown 1, and is not subject to any particular limitations regarding its type, arrangement, structure, material, dimensions, finish, etc., and encompasses all ventilation means.

[0092] The exhaust section 13 may be formed as a window that opens the rear of the Crown 1. Alternatively, the exhaust section 13 may also serve as a ventilation section 11 provided at the rear of the Crown 1.

[0093] The exhaust section 13 improves the ventilation inside the crown 1 by exhausting the air that the air intake section 2 has taken into the interior of the crown 1.

[0094] In a front projection view, the air intake sections 2 are located one each on the left and right sides of the outer edge of the crown 1, and one additional section at the top. In other words, the air intake sections 2 are also located behind the top of the crown 1.

[0095] The hat X includes a brim 4 provided at the rear lower edge of the crown 1. The brim 4 is formed to extend downward from the rear lower edge of the crown 1.

[0096] The canopy portion 4 has a main portion 41 and an opening edge portion 42 provided at the central front of the main portion 41. Preferably, the opening edge portion 42 is provided adjacent to the exhaust portion 13.

[0097] The opening edge 42 forms an opening d adjacent to the crown 1 at the rear of the crown 1. This improves vertical ventilation on the back of the neck. In particular, the air exhausted from the exhaust section 13 can be passed to the back of the neck, contributing to the user's comfort. Even under normal conditions, the main section 41 moves up and down, stirring up the air and thus creating actual ventilation on the back of the neck. [Explanation of symbols]
