Description

[Technical field]

[0001] The present invention relates to a neck cover. [Background technology]

[0002] There is a known technology (e.g., air-conditioned clothing) that blows air from a blower inside the clothing worn to evaporate sweat and remove the heat of vaporization. Patent Document 1 discloses a prior art in which a guide sheet is attached to the back collar of the air-conditioned clothing. In the prior art, the guide sheet is attached to the helmet along the back of the head, and the blower is operated to guide the air coming out from between the back collar and the neck through the gap between the guide sheet and the back of the head into the inside of the helmet, reducing stuffiness of the head. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2016 / 016996 Summary of the Invention [Problem to be solved by the invention]

[0004] In the prior art, some of the air coming out from between the rear collar and the neck escapes between the side of the head and the guide sheet, and the rest reaches the inside of the helmet. If the guide sheet is attached to the side of the head, the amount of air that escapes before reaching the helmet is reduced, but there is a problem that the guide sheet is attached to the head and feels uncomfortable to the wearer.

[0005] The present invention has been made to solve this problem, and has an object to provide a neck cover that can reduce the discomfort felt by the wearer and the passage of wind. [Means for solving the problem]

[0006] To achieve this object, the present invention provides a neck cover that covers at least a part of a wearer's neck, and includes an air passage through which air that enters a first opening exits from a second opening, the air passage including a first part and a second part disposed between the first part and the wearer. A cylindrical space through which air passes is provided between the first part and the second part, and when worn together with clothing, the first opening is located inside the clothing and the second opening is located outside the clothing. Effect of the Invention

[0007] According to the first aspect, the ventilation passage through which the wind that entered the first opening exits from the second opening includes a first part and a second part disposed between the first part and the wearer. When the neck cover is worn together with the garment, the first opening is located inside the garment, and the second opening is located outside the garment. Since a cylindrical space through which the wind passes is provided between the first and second parts of the ventilation passage, the passage of the wind between the first and second openings can be reduced without the ventilation passage being pressed against the wearer so as to cause the wearer to feel uncomfortable. This reduces the wearer's discomfort and the passage of the wind.

[0008] According to the second aspect, the first aspect further includes a reinforcing portion that reinforces at least one of the first portion and the second portion. The first opening includes the first portion and the second portion, and the reinforcing portion includes the reinforcing portion provided at a position that includes the first opening. This makes it easier for wind to enter the first opening.

[0009] According to the third aspect, in the second aspect, the reinforcing portion includes a first reinforcing portion disposed in the first portion. In a cross section perpendicular to the direction in which the ventilation passage extends, a line showing the first reinforcing portion includes an outwardly convex curve. This ensures a sufficient cross-sectional area for the ventilation passage.

[0010] According to the fourth aspect, in the second or third aspect, the reinforcing portion includes a plurality of first reinforcing portions arranged in the first portion in a line in a direction in which the ventilation passage extends. Adjacent reinforcing portions among the first reinforcing portions include overlapping portions that overlap each other in a thickness direction of the reinforcing portion. As a result, when the second portion is on the inside of the bend, the first reinforcing portions become an obstacle to each other at the overlapping portions, making it difficult for the ventilation passage to bend. Since the first reinforcing portion is not joined to the first portion in a portion including the overlapping portion, when the first portion is on the inside of the bend, the first portion sags away from the reinforcing portion at the overlapping portion, making it easier for the ventilation passage to bend.

[0011] According to the fifth aspect, in any one of the first to fourth aspects, when the neck cover is worn together with the headgear, the second opening faces the inside of the headgear, so that air can be blown toward the inside of the headgear, reducing stuffiness.

[0012] According to the sixth aspect, in the fifth aspect, the area of ​​the second opening is larger than the area of ​​the first opening. The airflow from the second opening can be spread, and the flow speed of the airflow from the second opening can be slower than the flow speed of the airflow entering the first opening. This can reduce stuffiness over a wide area inside the headgear.

[0013] According to the seventh aspect, in the fifth or sixth aspect, the width of the second portion in the first opening is narrower than the width of the second portion in the second opening. Since the wearer's neck is thinner than the head, by making the width of the second portion in the first opening narrower than the width of the second portion in the second opening, it is possible to further reduce discomfort around the wearer's neck.

[0014] According to an eighth aspect, in any one of the fifth to seventh aspects, the height of at least one of the first opening and the second opening relative to the garment is adjusted by the adjuster, allowing the first opening and / or the second opening to be positioned as desired depending on the wearer's neck length.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Fig. 1 is a perspective view of a neck cover 10 in one embodiment. The neck cover 10 has an air passage 11. In this embodiment, the neck cover 10 has a heat shield 50 arranged in the air passage 11. Fig. 1 illustrates a state in which the heat shield 50 has been removed from the air passage 11. In Fig. 1, the lower side of the paper surface is referred to as the lower side of the neck cover 10, and the upper side of the paper surface is referred to as the upper side of the neck cover 10 (the same applies to Figs. 2(a), 2(b), 3, 4(a), and 4(b)).

[0017] The ventilation passage 11 includes a first section 12 and a second section 13. In the ventilation passage 11, the edges on both sides in the width direction of the first section 12 and the second section 13 are connected to each other, and a cylindrical space 14 is provided between the first section 12 and the second section 13. A first opening 15 and a second opening 16 of the ventilation passage 11 are connected to the space 14. The wind that enters from the first opening 15 passes through the space 14 and exits from the second opening 16.

[0018] The second part 13 is a part whose outer surface faces the wearer 61 (see FIG. 3) when the neck cover 10 is worn. The first part 12 is a part located on the opposite side of the second part 13. When the neck cover 10 is worn, the second part 13 is located between the wearer 61 and the first part 12. The first part 12 and the second part 13 are made of a sheet-like material having low or no breathability. In this embodiment, the first opening 15 is provided at one end of the first part 12 and the second part 13 in the length direction and includes the first part 12 and the second part 13, and the second opening 16 is provided at one end of the first part 12 and the second part 13 in the length direction and includes the first part 12 and the second part 13.

[0019] It is of course possible to make the entire second part 13 out of a highly breathable material such as mesh weave, or to provide a mesh in part of the second part 13. Holes (openings) may be made in the second part 13 made of a sheet-like material with low or no breathability. In these cases, a second opening is provided in the second part 13, so that wind coming out of the second opening can be directed at the wearer 61. Similarly, holes may be made in the first part 12 or the second part 13, and the holes may be used as first openings.

[0020] Rails 17 extending in the direction in which ventilation passage 11 extends are provided on both sides in the width direction of second portion 13 near second opening 16. Rail 17 has a plurality of projections and recesses aligned in the longitudinal direction of rail 17. Rail 17 is made of, for example, synthetic resin.

[0021] The heat shield 50 is a member disposed around the neck 62 (see FIG. 3). The heat shield 50 includes a back portion 51, and a right side portion 54 and a left side portion 56 connected to the left and right side edges of the back portion 51, respectively. The back portion 51, the right side portion 54, and the left side portion 56 are made of a sheet-like material such as synthetic resin or natural fiber. A metal layer made by deposition or the like may be provided to improve heat shielding properties.

[0022] When the heat shielding part 50 is worn, the back part 51 is located behind the head 63 or neck 62 of the wearer 61 (see FIG. 3), and the right side part 54 and the left side part 56 are located on the left and right of the head 63 or neck 62, respectively. Meshes 55, 57 are provided in parts including the upper edges of the right side part 54 and the left side part 56, respectively. When the neck cover 10 is worn, the meshes 55, 57 are located near the ears of the wearer 61, ensuring that sounds can be easily heard. It is of course possible to make the entire heat shielding part 50 a mesh.

[0023] Near the upper edge of rear portion 51, sliders 52 are provided on both sides in the width direction of rear portion 51. Sliders 52 are attached to rails 17 provided in ventilation passage 11. When sliders 52 are attached to rails 17, heat shielding portion 50 is disposed in ventilation passage 11, and first portion 12 is positioned between second portion 13 of ventilation passage 11 and rear portion 51.

[0024] The slider 52 is provided with teeth. The teeth of the slider 52 engage with the unevenness of the rail 17 when the slider 52 is locked. When the slider 52 attached to the rail 17 is unlocked and moved along the rail 17, the entire ventilation passage 11 moves in the direction in which the ventilation passage 11 extends. When the slider 52 is locked, the teeth of the slider 52 engage with the unevenness of the rail 17, and the slider 52 is fixed to the rail 17 at the locked position. The rail 17 and the slider 52 constitute an adjustment tool 53 that adjusts the height of the first opening 15 and the second opening 16. When the adjustment tool 53 is removed, the ventilation passage 11 and the heat shielding part 50 can be separated, so that the ventilation passage 11 and the heat shielding part 50 can be washed separately.

[0025] The heat shielding part 50 is provided with an attachment part 58 for fixing the ventilation passage 11 to the wearer 61 (see FIG. 3) via the heat shielding part 50. In this embodiment, the attachment part 58 is a band arranged on the upper edge of the back part 51, the right side part 54, and the left side part 56. Fasteners 59 are provided on both ends of the attachment part 58. In this embodiment, the fasteners 59 are hook-and-loop fasteners, but they may be plug-in or hook-shaped fasteners. The attachment part 58 to which the fasteners 59 are attached is annular and expands and contracts in the length direction. The fasteners 59 are designed to come off when a large tensile force is applied to the fasteners 59. An anti-slip member 60 is provided on the inner surface of the attachment part 58 at the position of the back part 51.

[0026] 2(a) is a rear view of ventilation passage 11 with a part of first portion 12 cut away. When viewed from the rear side of ventilation passage 11, first portion 12 gradually widens in width from bottom to top. First reinforcing portions 18, 21, 24, and 27 that reinforce first portion 12 are provided on the surface of first portion 12 that contacts space 14.

[0027] The reinforcing parts 18, 21, 24, 27 are arranged in a line in the extension direction of the ventilation passage 11 in order from the bottom. The reinforcing parts 18, 21, 24, 27 are, for example, plates made of synthetic resin, paper, or metal that are harder than the first part 12. The plates have a curved surface with the center in the width direction protruding toward the back side. The plates are attached to the first part 12 by, for example, sewing with thread or metal fittings, bonding, or welding. In this embodiment, the reinforcing parts 18, 21, 24, 27 are attached to the first part 12 by sewing. The reinforcing parts 18, 21, 24, 27 are each provided over the entire width direction of the first part 12.

[0028] Reinforcing portion 18 maintains the shape of first opening 15 (see FIG. 1) and is provided along opening 15. An upper edge 19 of reinforcing portion 18 is a curve located on a plane approximately perpendicular to the extension direction of ventilation passage 11. A lower edge 20 of reinforcing portion 18 is a downwardly convex curve located on approximately the same curve as opening 15. The entire outer edge of reinforcing portion 18 is attached to first portion 12 by stitching.

[0029] The upper edge 22 of the reinforcement part 21 is a curve located on a plane that is approximately perpendicular to the extension direction of the ventilation passage 11. The central portion in the width direction of the lower edge 23 of the reinforcement part 21 is a curve that convex downwards. The outer edges of the reinforcement part 21, except for the lower edge 23, are attached to the first part 12 by sewing. The central portion in the width direction of the lower edge 23 of the reinforcement part 21 overlaps the front side of the upper edge 19 of the reinforcement part 18 when viewed from the rear side of the ventilation passage 11.

[0030] The upper edge 25 of the reinforcement part 24 is a curve located on a plane that is approximately perpendicular to the extension direction of the ventilation passage 11. The central portion in the width direction of the lower edge 26 of the reinforcement part 24 is a curve that convex downwards. The outer edges of the reinforcement part 24, except for the lower edge 26, are attached to the first part 12 by sewing. The central portion in the width direction of the lower edge 26 of the reinforcement part 24 overlaps the front side of the upper edge 22 of the reinforcement part 21 when viewed from the rear side of the ventilation passage 11.

[0031] The reinforcing portion 27 maintains the shape of the second opening 16 and is provided along the opening 16. The upper edge 28 of the reinforcing portion 27 is an upwardly convex curve and is located on approximately the same curve as the opening 16. The central portion in the width direction of the lower edge 29 of the reinforcing portion 27 is a downwardly convex curve. The outer edge of the reinforcing portion 27, except for the lower edge 29, is attached to the first portion 12 by sewing. The central portion in the width direction of the lower edge 29 of the reinforcing portion 27 overlaps the front side of the upper edge 25 of the reinforcing portion 24 when viewed from the rear side of the ventilation passage 11. The rail 17 spans the portion of the first portion 12 where the reinforcing portion 27 is provided and the portion where the reinforcing portion 24 is provided.

[0032] The overlapping parts 30, 31, and 32 are provided at the center of the width of the first part 12. The overlapping parts 30, 31, and 32 are aligned in the extension direction of the ventilation passage 11. In the overlapping part 30, the reinforcement part 18 and the reinforcement part 21 overlap in the thickness direction of the reinforcement parts 18 and 21 when viewed from the rear side of the ventilation passage 11. In the overlapping part 30, the upper edge 19 of the reinforcement part 18 and the lower edge 23 of the reinforcement part 21 are spaced apart in the extension direction of the ventilation passage 11. In the overlapping part 31, the reinforcement part 21 and the reinforcement part 24 overlap in the thickness direction of the reinforcement parts 21 and 24 when viewed from the rear side ... upper edge 22 of the reinforcement part 21 and the lower edge 26 of the reinforcement part 24 are spaced apart in the extension direction of the ventilation passage 11. At overlapping portion 32, reinforcing portion 24 and reinforcing portion 27 overlap in the thickness direction of reinforcing portions 24, 27 when viewed from the rear side of ventilation passage 11. At portions other than overlapping portion 32, upper edge 25 of reinforcing portion 24 and lower edge 29 of reinforcing portion 27 are spaced apart in the extension direction of ventilation passage 11.

[0033] 2(b) is a front view of ventilation passage 11 with a part of second portion 13 broken away. When viewed from the front side of ventilation passage 11, second portion 13 has a width that gradually increases from bottom to top. Therefore, the width of second portion 13 at first opening 15 (see FIG. 1) is narrower than the width of second portion 13 at second opening 16 (see FIG. 1). Reinforcing portions 33, 36, 39, and 42 that reinforce second portion 13 are provided on the surface of second portion 13 that contacts space 14.

[0034] The reinforcing parts 33, 36, 39, 42 are arranged in the extension direction of the ventilation passage 11 in order from the bottom. The reinforcing parts 33, 36, 39, 42 may be, for example, a plate material made of synthetic resin, paper, or metal harder than the second part 13, or an adhesive (synthetic resin) adhered to the second part 13 and hardened on the second part 13. The plate material is attached to the second part 13 by, for example, sewing, bonding, or welding with thread or metal fittings. In this embodiment, the reinforcing parts 33, 36, 39, 42 are attached to the second part 13 by sewing the entire outer edge of each plate material. The reinforcing parts 33, 36, 39, 42 have a curved surface with the center in the width direction raised toward the back side, and are each provided over the entire width direction of the second part 13.

[0035] The reinforcing portion 33 maintains the shape of the first opening 15 and is provided along the opening 15. An upper edge 34 of the reinforcing portion 33 is a curve located on a plane approximately perpendicular to the extension direction of the ventilation passage 11. A lower edge 35 of the reinforcing portion 33 is a downwardly convex curve and is located on approximately the same curve as the opening 15.

[0036] An upper edge 37 and a lower edge 38 of reinforcing portion 36, and an upper edge 40 and a lower edge 41 of reinforcing portion 39 are curved lines located on a plane substantially perpendicular to the extension direction of air passage 11. The lower edge 38 of reinforcing portion 36 is separated from the upper edge 34 of reinforcing portion 33 over its entire length. The lower edge 41 of reinforcing portion 39 is separated from the upper edge 37 of reinforcing portion 36 over its entire length.

[0037] The reinforcing portion 42 is a portion that maintains the shape of the second opening 16, and is provided along the opening 16. An upper edge 43 and a lower edge 44 of the reinforcing portion 42 are curved lines that are located on a plane that is approximately perpendicular to the direction in which the air passage 11 extends. The upper edge 43 of the reinforcing portion 42 is located on approximately the same curve as the opening 16. The lower edge 44 of the reinforcing portion 42 is separated from the upper edge 40 of the reinforcing portion 39 over its entire length.

[0038] 3 is a diagram showing a state in which a wearer 61 wears the neck cover 10 together with clothing 64 and a headgear 66. In FIG. 3, the meshes 55, 57 of the heat shielding portion 50 are omitted from the illustration.

[0039] The clothing 64 is made of a sheet-like material with low or no breathability, and covers the upper body of the wearer 61. A blower (not shown) is attached to the wearer 61 or the clothing 64. The blower blows air between the clothing 64 and the wearer 61. The air passes between the clothing 64 and the wearer 61, and exits the clothing 64 from between the neck 65 of the clothing 64 and the wearer 61. When the air passes between the clothing 64 and the wearer 61, the sweat of the wearer 61 evaporates, and the heat of vaporization is taken away, lowering the surface temperature of the wearer 61.

[0040] An interior lining (not shown) is attached to headgear 66 (a helmet in this embodiment) worn by a wearer 61. The interior lining creates a gap between the headgear 66 and the head 63. When the wearer 61 places the headgear 66 inside the annular attachment portion 58 of the neck cover 10 and attaches the neck cover 10 to the headgear 66, the heat shielding portion 50 of the neck cover 10 covers the head 63, neck 62, and neck area 65 of the clothing 64 of the wearer 61. The heat shielding portion 50 prevents the neck 62 and head 63 from getting sunburned. An anti-slip member 60 (see FIG. 1) is provided on the inner surface of the attachment portion 58, so that the attachment portion 58 is less likely to come off the headgear 66.

[0041] The ventilation passage 11 is suspended from the headgear 66 via the attachment portion 58, the heat shielding portion 50, and the adjustment tool 53. The wearer 61 adjusts the height of the ventilation passage 11 relative to the heat shielding portion 50 by the adjustment tool 53 (see FIG. 1) so that the first opening 15 of the ventilation passage 11 of the neck cover 10 is located inside the neck circumference 65 of the garment 64 and the second opening 16 is located at an appropriate height of the head 63. The second opening 16 faces the inside of the headgear 66. The second opening 16 may be located inside the headgear 66 or may be located under the headgear 66. The adjustment tool 53 allows the first opening 15 and the second opening 16 to be located at a position of the wearer 61's preference according to the wearer's 61 preference and the length of the neck 62.

[0042] When a blower (not shown) is operated to blow air between the garment 64 and the wearer 61, part of the air flowing from between the neck 65 and the wearer 61 toward the outside of the garment 64 enters the ventilation passage 11 from the first opening 15 and exits from the second opening 16. This reduces stuffiness inside the headgear 66. There is no need for the wearer 61 to perform an operation that would cause discomfort, such as tightly fitting the ventilation passage 11 to the wearer 61, and therefore the discomfort felt by the wearer 61 can be reduced. The air that exits from the neck 65 but does not enter the ventilation passage 11 evaporates sweat from the neck 62 and head 63 covered by the heat shielding part 50, lowering the temperature of the neck 62 and head 63.

[0043] Since the reinforcing parts 18, 21, 24, 27, 33, 36, 39, 42 are elastically deformed, when the neck circumference 65 is tightly fastened so that the gap between the neck 62 and the neck circumference 65 becomes small, the shape of the ventilation passage 11 is deformed to imitate the neck 62 and the neck circumference 65. This makes it possible to reduce the gap that is created by the ventilation passage 11 entering between the neck 62 and the neck circumference 65, thereby reducing the amount of wind that does not enter the ventilation passage 11 and goes out from the neck circumference 65.

[0044] Because the neck 62 of the wearer 61 is thinner than the head 63, the length of the neck circumference 65 of the garment 64 is shorter than the length of the inner circumference of the headwear 66. The width of the second portion 13 of the ventilation passage 11 at the first opening 15 located inside the neck circumference 65 of the garment 64 is narrower than the width of the second portion 13 at the second opening 16 facing the inside of the headwear 66, so that the discomfort around the neck circumference 65 of the wearer 61 can be further reduced.

[0045] 4(a) is a cross-sectional view of the ventilation passage 11 taken along the line IVa-IVa in FIG. 2(a). Both ends of the reinforcing portion 18 in the width direction are connected to both ends of the reinforcing portion 33 in the width direction. Both ends of the reinforcing portion 21 in the width direction are connected to both ends of the reinforcing portion 36 in the width direction. Both ends of the reinforcing portion 24 in the width direction are connected to both ends of the reinforcing portion 39 in the width direction. Both ends of the reinforcing portion 27 in the width direction are connected to both ends of the reinforcing portion 42 in the width direction. Since the reinforcing portions 18, 21, 24, 27, 33, 36, 39, and 42 provide portions with high rigidity intermittently in the extension direction of the ventilation passage 11, a space 14 can be secured between the first portion 12 and the second portion 13 of the ventilation passage 11, the space 14 being connected from the first opening 15 to the second opening 16.

[0046] A first reinforcing part 18 is provided at a position including the first opening 15 of the first part 12, and a second reinforcing part 33 is provided at a position including the first opening 15 of the second part 13. Since the shape of the first opening 15 can be maintained, wind can easily enter the first opening 15.

[0047] A first reinforcing part 27 is provided at a position including the second opening 16 of the first part 12, and a second reinforcing part 42 is provided at a position including the second opening 16 of the second part 13. Since the shape of the second opening 16 can be maintained, wind can easily come out from the second opening 16.

[0048] At the overlapping portion 30, the lower edge 23 of the reinforcement portion 21 is located between the reinforcement portion 18 and the second portion 13. At the overlapping portion 31, the lower edge 26 of the reinforcement portion 24 is located between the reinforcement portion 21 and the second portion 13. At the overlapping portion 32, the lower edge 29 of the reinforcement portion 27 is located between the reinforcement portion 24 and the second portion 13. Since the overlapping portions 30, 31, and 32 provided in the first portion 12 are aligned in the extension direction of the ventilation passage 11, when the second portion 13 is on the inside of the bend, the reinforcement portions 18, 21, 24, and 27 interfere with each other at the overlapping portions 30, 31, and 32. This makes it easier for the ventilation passage 11 to maintain its shape. When the wearer 61 looks down or the like and the ventilation passage 11 bends with the second portion 13 on the inside of the bend, the portions of the first portion 12 on both sides in the width direction of the overlapping portions 30, 31, 32 sag, and the portions of the second portion 13 without the reinforcing portions 33, 36, 39, 42 deform.

[0049] The overlapping portions 30, 31, 32 aligned in the extension direction of the ventilation passage 11 are located at the center in the width direction of the first portion 12, and the reinforcement portions 18, 21, 24, 27 are spaced apart from each other except for the overlapping portions 30, 31, 32. Furthermore, since the reinforcement portions 33, 36, 39, 42 aligned in the extension direction of the ventilation passage 11 are spaced apart from each other, when the wearer 61 tilts his / her neck 62 left / right, for example, and the ventilation passage 11 bends left / right, the portions of the first portion 12 on both sides of the overlapping portions 30, 31, 32 in the width direction are deformed, and the portions of the second portion 13 without the reinforcement portions 33, 36, 39, 42 are deformed.

[0050] FIG. 4(b) is a cross-sectional view of the ventilation passage 11 when the first part 12 is on the inside of the bend. The part including the overlapping part 30 of the lower edge 23 of the reinforcement part 21, the part including the overlapping part 31 of the lower edge 26 of the reinforcement part 24, and the part including the overlapping part 32 of the lower edge 29 of the reinforcement part 27 are not attached to the first part 12 and are not joined. Therefore, when the first part 12 is on the inside of the bend, the first part 12 sags away from the reinforcement parts 21, 24, 27 at the overlapping parts 30, 31, 32, and the part of the second part 13 without the reinforcement parts 33, 36, 39, 42 is deformed. This allows the ventilation passage 11 to bend along the curve from the back of the head to the neck 62 of the wearer 61. When the wearer 61 looks up, the ventilation passage 11 is bent further with a small force, so that the discomfort of the wearer 61 can be reduced.

[0051] FIG. 5(a) is a cross-sectional view of the neck cover 10 taken along line Va-Va in FIG. 3. The ventilation passage 11 is located between the heat shielding portion 50 and the head 63. The cross-sectional shape of the ventilation passage 11 is a bow shape with the reinforcement portion 27 provided in the first portion 12 as an arc and the reinforcement portion 42 provided in the second portion 13 as a chord. The line indicating the reinforcement portion 27 includes a curved line that is convex toward the outside of the space 14. This makes it possible to increase the rigidity of the reinforcement portion 27 while ensuring the cross-sectional area of ​​the space 14. The line indicating the reinforcement portion 42 provided in the second portion 13 includes a curved line that is convex toward the inside of the space 14. The curvature of the line indicating the reinforcement portion 42 is smaller than the curvature of the line indicating the reinforcement portion 27, so that the force when the second portion 13 hits the head 63 is dispersed, thereby reducing discomfort.

[0052] 5(b) is a cross-sectional view of the neck cover 10 taken along line Vb-Vb in FIG. 3. The air passage 11 is located between the neck circumference 65 and the neck 62. The neck circumference 65 is located between the air passage 11 and the heat shield 50. The line indicating the reinforcing portion 18 provided in the first portion 12 includes a curved line that is convex toward the outside of the space 14. This allows the stiffness of the reinforcing portion 18 to be increased while ensuring the cross-sectional area of ​​the space 14. The line indicating the reinforcing portion 33 provided in the second portion 13 includes a curved line that is convex toward the inside of the space 14. The curvature of the line indicating the reinforcing portion 33 is smaller than the curvature of the line indicating the reinforcing portion 18, so that the force when the second portion 13 hits the neck 62 is dispersed, reducing discomfort.

[0053] The area of ​​the space 14 in Fig. 5(a) is larger than the area of ​​the space 14 in Fig. 5(b). That is, the area of ​​the second opening 16 (see Fig. 3) is larger than the area of ​​the first opening 15. This allows the wind coming out of the second opening 16 to spread inside the headgear 66, while making the flow speed of the wind coming out of the second opening 16 slower than the flow speed of the wind entering the first opening 15. This makes it possible to reduce stuffiness over a wide area inside the headgear 66.

[0054] Since the fastener 59 provided on the attachment portion 58 is designed to come off when a large pulling force is applied to the fastener 59, in the unlikely event that the neck cover 10 is caught in a machine, the fastener 59 comes off and the neck cover 10 comes off from the wearer 61. Since the wearer 61 can be prevented from being caught in the machine, the safety of the wearer 61 can be ensured.

[0055] Although the present invention has been described above based on the embodiment, the present invention is not limited to the above embodiment, and it can be easily assumed that various improvements and modifications are possible within the scope of the present invention. For example, the shapes of the ventilation passage 11 and the heat shielding portion 50, and the shapes and numbers of the reinforcing portions 18, 21, 24, 27, 33, 36, 39, 42, etc. can be appropriately set.

[0056] In the embodiment, the cross section of the ventilation passage 11 is described as being arch-shaped, but this is not necessarily limited to this. The cross section of the ventilation passage 11 can be set to any shape. Examples of the cross section of the ventilation passage 11 include a circle, a semicircle, an ellipse, a rectangle, a triangle, and a trapezoid.

[0057] In the embodiment, a case where reinforcing parts are arranged in both the first part 12 and the second part 13 of the ventilation passage 11 has been described, but this is not necessarily limited to this. It is naturally possible to provide a reinforcing part in either the first part 12 or the second part 13. For example, even if the reinforcing parts 33, 36, 39, 42 arranged in the second part 13 are omitted, the space 14 can be secured by the reinforcing parts 18, 21, 24, 27 arranged in the first part 12. It is also naturally possible to arrange the reinforcing parts 18, 21, 24, 27 in the second part 13 and omit the reinforcing part in the first part 12.

[0058] In the embodiment, the cylindrical ventilation passage 11 in which the hard plate-like reinforcing part is arranged on the soft cylindrical material has been described, but the present invention is not necessarily limited to this. Of course, it is possible to create a cylindrical ventilation passage by alternately connecting hard ring-shaped reinforcing parts and soft ring-shaped materials. The part of the cylindrical ventilation passage whose outer surface faces the wearer is the second part, and the part located on the opposite side of the second part is the first part.

[0059] In the embodiment, the case where the ventilation passage 11 is attached to the heat shielding part 50 and the attachment part 58 of the heat shielding part 50 is attached to the headgear 66 has been described, but this is not necessarily limited to this. It is of course possible to omit the heat shielding part 50 and attach the ventilation passage 11 to the headgear 66 so that the first opening 15 of the ventilation passage 11 is located inside the clothing 64. Even without the heat shielding part 50, the ventilation passage 11 covers a part of the neck 62. Similarly, it is of course possible to omit the heat shielding part 50 and attach the ventilation passage 11 to the clothing 64 so that the second opening 16 of the ventilation passage 11 is located inside the headgear 66. In these cases, the heat shielding part 50 may be wrapped around the neck 62 to cover the ventilation passage 11.

[0060] In the case of clothing with a hood, clothing with a collar that can be stood up along the neck 62, or clothing with a tubular collar such as a turtleneck, the heat shield 50 can be omitted and the ventilation passage 11 can be arranged in the hood or collar.

[0061] In the embodiment, the case where the wearer 61 wearing the headgear 66 wears the neck cover 10 has been described, but this is not necessarily limited to this. It is of course possible for the wearer 61 not wearing the headgear 66 to wear the neck cover 10. This is because, in this case as well, the wind inside the garment 64 can be used to evaporate the sweat of the wearer 61 outside the garment 64.

[0062] In the embodiment, the neck cover 10 is provided with the heat shield 50 including the back portion 51, the right side portion 54, and the left side portion 56, but this is not necessarily limited to this. It is of course possible to omit the right side portion 54 and the left side portion 56.

[0063] In the embodiment, the heat shielding part 50 is described as covering the back, right side and left side of the neck 62 and leaving the front of the neck 62 open, but this is not necessarily limited to this. It is of course possible to provide the heat shielding part 50 with a portion that covers the front of the neck 62, to make it into a heat shielding part that covers the entire circumference of the neck 62 (wrapped around the neck 62). In this case, it is of course possible to attach the ventilation passage 11 to the heat shielding part wrapped around the neck 62. This makes it possible to eliminate the need for the attachment part 58 for attaching the heat shielding part 50 to the headgear 66, as described in the embodiment.

[0064] In the embodiment, the case where the headgear 66 is fitted into the annular mounting portion 58 provided on the heat shield 50 and the ventilation passage 11 is attached to the headgear 66 has been described, but this is not necessarily limited to this. It is of course possible to provide a band (mounting portion) on the heat shield 50 and attach the ventilation passage 11 to the headgear 66 by hanging the band on the interior (not shown) of the headgear 66. It is of course possible to provide the band with a fastener that comes off when a large force is applied.

[0065] In the embodiment, the headgear 66 is described by taking a helmet as an example, but is not necessarily limited to this. The headgear 66 may be a hat. As with a helmet, it is of course possible to provide an interior lining in the hat (headgear) and provide a gap between the hat and the head 63.

[0066] In the embodiment, the adjustment tool 53 including the slider 52 provided on the heat shielding part 50 and the rail 17 provided on the ventilation passage 11 has been described, but this is not necessarily limited to this. Conversely, it is of course possible to provide the slider 52 on the ventilation passage 11 and the rail 17 on the heat shielding part 50. In addition, a telescopic ventilation passage may be created by combining multiple cylinders, and one of the cylinders may be fixed to the heat shielding part 50, and the total length of the ventilation passage may be changed by pulling out or storing another cylinder. The other cylinder that can be pulled out or stored constitutes an adjustment tool that adjusts the position of at least one of the first opening and the second opening. If the other cylinder can be pulled out from one end of the cylinder fixed to the heat shielding part, the position of the first opening or the second opening can be adjusted. If the other cylinder can be pulled out from both ends of the cylinder fixed to the heat shielding part, the positions of the first opening and the second opening can be adjusted.

[0067] In the embodiment, a case has been described in which substantially the entire lower edges 23, 26, 29 of the reinforcing portions 21, 24, 27 are not joined to the first portion 12, but this is not necessarily limited to this. If the range including the portion of the first portion 12 overlapping with the overlapping portions 30, 31, 32 is not joined to the reinforcing portions 21, 24, 27, when the first portion 12 is placed on the inside of the bend, the first portion 12 will sag away from the reinforcing portions 21, 24, 27 at the overlapping portions 30, 31, 32.

[0068] Although not described in the embodiment, the second portion 13 of the ventilation passage 11 can be made of a material that has a cool-to-the-touch feel. This allows the wearer 61 to feel a cool sensation when the second portion 13 touches the neck 62. Also, the first portion 12 of the ventilation passage 11 can be made of a water-absorbent material, or a water-absorbent material can be disposed in the first portion 12. The water contained in the water-absorbent material absorbs the heat of vaporization when it evaporates, thereby reducing the temperature rise in the ventilation passage 11. [Explanation of symbols]
