Description

Group of protrusions for headgear, headgear including the same, and protrusion member for headgear

[0001] The present disclosure relates to a group of ridges for a headgear, a headgear including the same, and a ridge member for a headgear.

[0002] Patent Document 1 describes a headgear with multiple ridges that can drain water droplets to a side out of the user's field of view. The multiple ridges are each located on the upper surface of the flat visor of the headgear. The multiple ridges are each curved at a predetermined curvature so as to protrude toward the crown side of the headgear when viewed from above, and extend approximately parallel to each other.

[0003] Japanese Patent Application Laid-Open No. 2000-08218

[0004] In the headgear, the multiple ridges are each curved at a predetermined curvature so as to protrude toward the crown when viewed from above, allowing water droplets to run down the multiple ridges and be discharged forward, which can cause water droplets to fall into the user's field of vision.

[0005] Therefore, the present disclosure aims to provide a group of protrusions for headgear, a headgear equipped therewith, and a protrusion member for a headgear that further prevents water droplets from falling into the user's field of vision compared to conventional technology.

[0006] A group of ridges for a headgear according to one aspect of the present disclosure includes a crown that covers the head of a user and a visor connected to a front end of the crown, the crown including crown side portions that cover the sides of the head, the visor including an outer surface that extends downward from a left-right center of the visor outward in the left-right direction and facing upward, the group including: a first ridge that is arranged along a boundary between the outer surface of the crown and the outer surface of the visor and extends from the left-right center of the boundary to the crown side portions; a second ridge that is arranged along the front end of the outer surface of the visor and extends to the crown side portions; and a third ridge that is arranged between the first ridge and the second ridge in the front-to-rear direction on the outer surface of the visor when viewed from above and extends from the left-right center of the outer surface of the visor to the crown side portions.

[0007] A headgear according to one aspect of the present disclosure includes a group of ridges for the headgear.

[0008] A protrusion member for a headgear according to one aspect of the present disclosure comprises an elongated protrusion body having a bottom surface and a protruding end opposite the bottom surface, and an adhesive layer provided on the bottom surface of the protrusion body for attaching it to the outer surface of the headgear, wherein the cross section of the protrusion body has a tapered shape that tapers toward the protruding end, and the apex of the tapered shape is located outward in the width direction of the tapered shape than the base of the tapered shape.

[0009] According to one aspect of the present disclosure, a group of protrusions for a headgear, a headgear including the same, and a protrusion member for a headgear can further prevent water droplets from falling into the user's field of vision compared to conventional technology.

[0010] Fig. 1A is a side view of the headgear according to the embodiment, Fig. 1B is a perspective view of the headgear as viewed from above and from the front, Fig. 2A is a cross-sectional view taken along line IIA-IIA in Fig. 1B, Fig. 2B is a cross-sectional view taken along line IIB-IIB in Fig. 1A, and Fig. 2C is a cross-sectional view corresponding to Fig. 2A of the headgear according to a modified example.

[0011] Hereinafter, an embodiment will be described with reference to the drawings. In the following description, when a portion of the visor 15 of the headgear 1A located on a center line CL (hereinafter simply referred to as the "left-right center line CL") that passes through the left-right center of the headgear 1A and extends in the front-rear direction extends horizontally, the vertical direction perpendicular to the left-right direction is defined as the up-down direction, and the direction perpendicular to the left-right direction and the up-down direction is defined as the front-rear direction.

[0012] Fig. 1A is a side view of a headgear 1A according to an embodiment. Fig. 1B is a perspective view of the headgear 1A as viewed from above and from the front. As shown in Figs. 1A and 1B, the headgear 1A is a baseball helmet. The headgear 1A includes a headgear main body 2 and a headgear ridge group 3A (hereinafter simply referred to as "ridge group 3A") fixed to the outer surface of the headgear main body 2.

[0013] The headgear main body 2 includes a crown 10 that covers the user's head, a visor 15 connected to the front end of the crown 10, and a pair of earmuffs 20 that cover the user's ears. Note that in Fig. 1A, only one of the pair of earmuffs 20 is visible, and the other earmuff 20 is hidden by the other earmuff 20 and is not visible.

[0014] The headgear main body 2 is an integrated unit consisting of the crown 10, the visor 15, and a pair of earmuffs 20. The material of the headgear main body 2 may be a thermosetting resin (for example, fiber reinforced plastic) or a thermoplastic resin (for example, ABS resin (acrylonitrile butadiene styrene resin)). A foamed resin (for example, polystyrene foam) for shock absorption may be arranged inside the crown 10 and the pair of earmuffs 20. The outer surface of the headgear main body 2 may be coated with a glossy paint.

[0015] The crown 10 includes a frontal crown 11 that covers the front of the user's head and is connected to the rear end of the visor 15, an occipital crown 12 that covers the back of the user's head, a pair of side crowns 13 that cover a pair of the user's sides and are connected to the upper ends of the pair of earmuffs 20, and a top crown 14 that covers the top of the user's head and is connected to the upper ends of the frontal crown 11, the occipital crown 12, and the pair of side crowns 13. Note that in Fig. 1A, only one of the pair of side crowns 13 is visible, and the other side crown 13 is hidden by the other side crown 13 and is not visible.

[0016] The visor 15 includes an outer surface 16 that extends downward from a central portion of the visor 15 in the left-right direction outward and faces upward. A glossy paint is applied to the outer surface 16 except for a front end portion 18 thereof. The front end portion 18 has a protrusion that protrudes upward from the outer surface 16 of the visor 15. The front end portion 18 does not have to have the protrusion. The glossy paint may also be applied to the front end portion 18, so that the entire outer surface 16 is coated with a glossy paint.

[0017] The outer surface 16 of the visor 15 is symmetrical with respect to the center line CL in the left-right direction when viewed from above. Therefore, hereinafter, only the left side portion of the outer surface 16 will be described unless otherwise necessary, and similar descriptions of the right side portion of the outer surface 16 will not be repeated. The front end of one side portion in the left-right direction of the outer surface 16 (in other words, the left side portion) has a curved shape that is convex forward and leftward when viewed from above. When viewed from the side, this curved shape extends downward and rearward from the front end of the outer surface 16 on the center line CL at a relatively steep incline (inclined relative to the horizontal), then bends, and extends downward and rearward at a gradual incline (inclined relative to the horizontal) toward the crown side portions 13. The incline of the curved shape after bending is gentler than the incline (inclined relative to the horizontal) of each of the first protrusion 31 and the third protrusion 33, described below, toward the crown side portions 13.

[0018] The group of protrusions 3A is arranged along a boundary 25 (hereinafter simply referred to as the "boundary 25") between the outer surface of the crown 10 and the outer surface of the visor 15, and comprises a first protrusion 31 extending from the center of the boundary 25 in the left-right direction to the crown side head 13, a second protrusion 32 arranged along the front end of the outer surface 16 of the visor 15 and extending to the crown side head 13, and a third protrusion 33 arranged in a portion of the outer surface 16 between the first protrusion 31 and the second protrusion 32 in the front-to-rear direction, and extending from the center of the outer surface 16 in the left-to-right direction to the crown side head 13.

[0019] The first protrusion 31 extends along the boundary 25 from above the left-right center line CL to each of the pair of crown side heads 13. The first protrusion 31 may extend along the boundary 25 from above the left-right center line CL to each of the pair of crown side heads 13, or may extend adjacent to the boundary 25 and parallel to the boundary 25. The left-right central portion of the first protrusion 31 is curved with a predetermined curvature so as to protrude forward (opposite the crown 10) when viewed from above. The first protrusion 31 is symmetrical with respect to the left-right center line CL when viewed from above.

[0020] The second ridge 32 extends from above the center line CL in the left-right direction at the front end of the outer surface 16 of the visor 15 to each of the crown side heads 13 and the other crown side heads 13 along the front end of the outer surface 16. In FIGS. 1A and 1B , the second ridge 32 is shown adjacent to the front end 18 of the visor 15 on the rear side. However, this is not limited to this, and the front end 18 may not have a protrusion that protrudes above the outer surface 16, and the second ridge 32 may be disposed on the front end 18. One side portion in the left-right direction of the second ridge 32 (in other words, the left side portion) has a curved shape that is convex forward and leftward when viewed from above. The convex curved shape of the second ridge 32 is similar to the convex curved shape of one side portion in the left-right direction of the outer surface 16 described above, and therefore similar description will not be repeated here. The other side of the second ridge 32 in the left-right direction (in other words, the right side) is symmetrical with the one side of the second ridge 32 in the left-right direction about the center line CL in the left-right direction when viewed from above.

[0021] The third protrusion streak 33 extends along the left-right center line CL from a central portion of the outer surface 16 of the visor 15 in the front-rear direction to each of the pair of crown side heads 13 along the central portion of the outer surface 16 in the front-rear direction. The central portion of the third protrusion streak 33 in the left-right direction is curved with a predetermined curvature in a convex shape toward the front (the side opposite the crown 10) when viewed from above. The curvature of the third protrusion streak 33 is greater than the curvature of the first protrusion streak 31 described above. As a result, when viewed from the side, the inclination of the third protrusion streak 33 toward one of the crown side heads 13 (with respect to the horizontal) is gentler than the inclination of the first protrusion streak 31 toward one of the crown side heads 13 (with respect to the horizontal). The third protrusion streak 33 is symmetrical about the left-right center line CL when viewed from above.

[0022] The end of the third protrusion 33 on the crown side head 13 side is located between the end of the first protrusion 31 on the crown side head 13 side and the end of the second protrusion 32 on the crown side head 13 side in the vertical direction, and is located on the same first imaginary straight line VL1 extending in the vertical direction as the end of the first protrusion 31 and the end of the second protrusion 32.

[0023] When viewed from the side, the distance between the first ridges 31 and the third ridges 33, and the distance between the third ridges 33 and the second ridges 32, each become smaller from the center in the left-right direction of the outer surface 16 of the visor 15 toward the crown side head portion 13. When viewed from the side, the end of the first ridges 31 on the crown side head portion 13 side, the end of the third ridges 33 on the crown side head portion 13 side, and the end of the second ridges 32 on the crown side head portion 13 side are adjacent to one another in the up-down direction.

[0024] As described above, the second ridges 32 have a curved portion when viewed from the side. On the other hand, the first ridges 31 and the third ridges 33 do not have a curved portion like the second ridges 32, and are gently inclined downward and rearward (inclined relative to the horizontal) toward the crown temporal portion 13 when viewed from the side.

[0025] With respect to a length region on the centerline CL of the outer surface 16 of the visor 15 in the left-right direction, the rear end of the outer surface 16 is defined as 0% and the front end of the outer surface 16 is defined as 100%. In this case, the front end 18 of the visor 15 is located in a region of 95% or more and less than 100% of the length region. The first ridges 31 are arranged in a region of 0% or more and 30% or less, preferably 0% or more and 5% or less, of the length region. The first ridges 31 may also be arranged along the boundary 25 on the outer surface of the crown 10. In this case, with respect to a length region obtained by extending the length region along the outer surface of the crown 10 on the negative side, the first ridges 31 are arranged in a region of -30% or more and 0% or less, preferably -10% or more and 0% or less. The second ridges 32 are arranged in a region of 70% or more and 100% or less, preferably 90% or more and 100% or less of the length region. The third ridge 33 is disposed between the first ridge 31 and the second ridge 32 in the length region.

[0026] Figure 2A is a cross-sectional view taken along line IIA-IIA in Figure 1B, and Figure 2B is a cross-sectional view taken along line IIB-IIB in Figure 1A. As shown in Figures 2A and 2B, the first to third ridges 31 to 33 each have an elongated adhesive layer 41 whose underside is adhered to the outer surface 16 of the visor 15, and an elongated ridge body 40 whose underside is adhered to the upper surface of the adhesive layer 41. The first to third ridges 31 to 33 have the same structure. Therefore, only the third ridge 33 will be described below, and similar descriptions of the first ridge 31 and second ridge 32 will not be repeated.

[0027] The adhesive layer 41 may be double-sided tape. Alternatively, the adhesive layer 41 may be an adhesive applied directly to the bottom surface 43 of the ridge body 40, or may be arranged in another manner on the bottom surface 43 of the ridge body 40. The width dimension of the adhesive layer 41 may be smaller than the width dimension of the ridge body 40. This allows, for example, when the adhesive layer 41 is double-sided tape and is manually attached to the bottom surface 43 of the ridge body 40, the adhesive layer 41 can be easily attached to the bottom surface 43 so that the adhesive layer 41 is enclosed within the bottom surface 43 when the ridge body 40 is viewed from the bottom surface 43 side.

[0028] The protrusion body 40 has a protruding end 42. The cross section of the protrusion body 40 has a tapered shape that narrows as it moves away from the outer surface 16 of the visor 15. The apex 42a of the tapered shape is located outward in the width direction of the tapered shape from the base 43a of the tapered shape. In the state shown in FIG. 2A , the tapered shape has one oblique side 44a facing the crown 10 and another oblique side 45a facing the opposite side from the crown 10. The apex 42a is part of the protruding end 42 of the protrusion body 40. The base 43a is part of the bottom surface 43 of the protrusion body 40 facing the outer surface 16. The one oblique side 44a is part of one oblique surface 44 of the protrusion body 40 facing the crown 10. The other oblique side 45a is part of the other oblique surface 45 of the protrusion body 40 facing the opposite side from the crown 10.

[0029] As shown in Figures 2A and 2B, a second imaginary straight line VL2 is defined, passing through one end of the tapered base 43a on the vertex 42a side in the width direction and perpendicular to the base 43a. As shown in Figure 2A, in the portion of the protrusion main body 40 located in the center of the visor 15 in the left-right direction, the vertex 42a is located rearward of the second imaginary straight line VL2. As a result, in at least the portion of the protrusion main body 40 of each of the second and third protrusions 32, 33 located in the center of the visor 15 in the left-right direction, one oblique side 44a is inclined to extend rearward and upward, and the other oblique side 45a is inclined to extend rearward and upward at a steeper slope than the one oblique side 44a. Furthermore, as shown in Figure 2B, in the portions of the protrusion main body 40 located at both ends of the visor 15 in the left-right direction, the vertex 42a is located above the second imaginary straight line VL2. As a result, in the portions of the protrusion body 40 of each of the first to third protrusions 31 to 33 located at both ends of the visor 15 in the left-right direction, one oblique side 44a is inclined to extend sideways and upward, and the other oblique side 45a is inclined to extend sideways and upward at a steeper slope than the one oblique side 44a.

[0030] For example, if the headgear 1A is a baseball helmet and the outer surface 16 of the visor 15 is painted with a glossy black paint, at least the other slope 45 of the ridge body 40 (i.e., the slope 45 of the ridge body 40 facing away from the crown 10 in the state shown in FIG. 2A ) may be painted with the same glossy black paint as the outer surface 16. This allows the third ridge 33 to be placed on the outer surface 16 without looking out of place. The ridge body 40 may be made of, for example, polyvinyl chloride (PVC). This makes it easier for the adhesive layer 41 to adhere to the bottom surface 43 of the ridge body 40. The ridge body 40 may also be made of a resin such as rubber, a sponge, or other substance.

[0031] For example, the first to third ridges 31-33 may be sold separately from the headgear main body 2, and the user may arrange the first to third ridges 31-33 on the headgear 1A themselves. In this case, a guide sheet shaped to correspond to the outer surface 16 of the visor 15 and an instruction manual may be prepared along with the first to third ridges 31-33, and the first to third ridges 31-33, guide sheet, and instruction manual may be sold as a headgear ridge group attachment set. The guide sheet has a shape that corresponds to the outer surface 16. The guide sheet has an adhesive layer that is attached to the outer surface 16 and a surface layer that is laminated on the adhesive layer and to which the first to third ridges 31-33 are attached. The surface layer has lines marked on it at the locations where the first to third ridges 31-33 should be attached. This allows the user to attach the guide sheet to the outer surface 16 while referring to the instructions, and then attach the first to third ridges 31 to 33 to the guide sheet along the lines, thereby allowing the user to easily position the ridge group 3A on the headgear 1A.

[0032] The guide sheet may have elongated holes instead of the lines at locations on the surface layer where the first to third ridges 31 to 33 should be attached. This allows the user to attach the guide sheet to the outer surface 16 of the visor 15 while referring to the instructions, and then attach the first to third ridges 31 to 33 to the portions of the outer surface 16 that are exposed through the multiple holes in the guide sheet. In such a case, after attaching the first to third ridges 31 to 33 to the outer surface 16, the user may remove only the guide sheet from the outer surface 16. Instead of the instructions, a sheet of paper with a URL written on it may be prepared, and the user may attach the first to third ridges 31 to 33 to the outer surface 16 while referring to the instructions posted at the URL.

[0033] According to the configuration described above, water droplets sliding down the outer surface of the crown 10 toward the visor 15 collide with the first ridges 31 arranged along the boundary 25. As a result, the water droplets travel along the first ridges 31 and are discharged to the side. Even if the water droplets travel forward over the first ridges 31, the water droplets are slowed down by the collision with the first ridges 31 and then collide with the third ridges 33 arranged on the outer surface 16 of the visor 15 and extending toward the crown temporal region 13. As a result, the water droplets travel along the third ridges 33 and are discharged to the side without traveling forward over the third ridges 33. Here, because the third ridges 33 are arranged between the first ridges 31 and the second ridges 32 arranged along the front end of the outer surface 16 in the front-to-rear direction when viewed from above, the water droplets are discharged to the side at a position away from the front end of the visor 15. That is, even if water droplets do pass forward over the third ridge 33, they can flow sideways along the outer surface 16, reducing the possibility of them passing forward over the front end of the visor 15 and falling. As described above, water droplets are more effectively prevented from falling into the user's field of vision than in the prior art. Even if water droplets reach the front end of the outer surface 16, they are discharged sideways along the second ridge 32. Furthermore, even if water droplets are not discharged sideways along any of the first to third ridges 31 to 33, they can be kept on the outer surface 16 of the visor 15 by any of the first to third ridges 31 to 33 for a predetermined period of time (e.g., while the user is standing in the batter's box), thereby preventing water droplets from falling into the user's field of vision for that period of time.

[0034] The end of the third ridge 33 on the crown side head 13 side is located on the same first imaginary line VL1 extending in the vertical direction as the end of the first ridge 31 on the crown side head 13 side and the end of the second ridge 32 on the crown side head 13 side, so water droplets that are discharged laterally along the third ridge 33 fall downward while absorbing water droplets that are discharged laterally along the first ridge 31 and the second ridge 32. This can improve drainage efficiency.

[0035] The cross section of the ridge body 40 has a tapered shape that narrows as it moves away from the outer surface 16 of the visor 15. With this configuration, water droplets that fall directly onto the first to third ridges 31 to 33 are less likely to remain on the outer surface of each of the first to third ridges 31 to 33 than, for example, when the cross section of each of the first to third ridges 31 to 33 is square. This can improve drainage efficiency.

[0036] The apex 42a of the tapered cross section of each of the first to third protrusions 31 to 33 is located outward in the width direction of the tapered shape relative to the base 43a of the tapered shape. At least in the portion of the protrusion body 40 of each of the second and third protrusions 32, 33 located in the center of the visor 15 in the left-right direction, the oblique sides 44a are inclined to extend rearward and upward, thereby preventing water droplets from riding forward over at least the second and third protrusions 32, 33. This further prevents water droplets from falling into the user's field of vision. Furthermore, in the portion of the protrusion body 40 of each of the first to third protrusions 31 to 33 located at both ends of the visor 15 in the left-right direction, the oblique sides 44a are inclined to extend sideways and upward, thereby preventing water droplets from falling from each of the first to third protrusions 31 to 33 and allowing them to travel along the portion to the end of each of the first to third protrusions 31 to 33 near the crown temporal head 13.

[0037] As described above, the first ridges 31 and the third ridges 33 are each inclined gradually downward and rearward toward the crown temporal region 13 at a steeper gradient than the second ridges 32 when viewed from the side, so that water droplets can be smoothly drained to the side along the first ridges 31 and the third ridges 33. This can improve drainage efficiency.

[0038] The technology of the present disclosure is not limited to the above-described configuration. Fig. 2C is a cross-sectional view of a modified headgear 1B corresponding to Fig. 2A. Note that headgear 1B has the same structure as headgear 1A, except that it has ridge group 3B instead of ridge group 3A. Therefore, the same or similar parts are given the same reference numerals, and similar descriptions will not be repeated.

[0039] As shown in Fig. 2C, the ridge group 3B arranged on the headgear 1B has a base portion 46 having a shape corresponding to the outer surface 16 of the visor 15, an adhesive layer 41 bonded to the underside of the base portion 46 and having a shape corresponding to the base portion 46, and first to third ridges 31 to 33 protruding from the upper surface of the base portion 46. The first to third ridges 31 to 33 each include a ridge body 40. The ridge body 40 has a structure similar to that of the ridge body 40 in the ridge group 3A described above, except that it is integral with the base portion 46. Therefore, similar descriptions will not be repeated here.

[0040] According to the above configuration, by simply adhering one adhesive layer 41 to the outer surface 16 of the visor 15, all of the ridge group 3B (in other words, all of the first to third ridges 31 to 33) can be arranged on the outer surface 16. Therefore, the ridge group 3B can be easily arranged on the outer surface 16.

[0041] In the above embodiment, a case has been described in which the apex 42a of the tapered shape of the cross section of the protrusion body 40 is located outward in the width direction of the tapered shape from the base 43a of the tapered shape, and one oblique side 44a and the other oblique side 45a are each inclined to extend rearward and upward at a portion of the third protrusion 33 located in the center in the left-right direction of the outer surface 16 of the visor 15, and are inclined to extend sideways and upward at portions of the third protrusion 33 located at both ends in the left-right direction of the outer surface 16. However, this is not limited to this case, and for example, one oblique side 44a and the other oblique side 45a may each be inclined to extend forward and upward at a portion of the third protrusion 33 located in the center in the left-right direction of the outer surface 16, and be inclined to extend sideways and downward at portions of the third protrusion 33 located at both ends in the left-right direction of the outer surface 16. With this configuration, the slope 44 of the ridge body 40 facing the crown 10 is larger than the slope 44 of the headgear 1A, making it easier for water droplets to fall directly onto the slope 44. Therefore, water droplets that fall directly onto the third ridges 33 are more likely to be discharged to the side along the slope 44, further preventing water droplets from falling into the user's field of vision. Note that by giving the first ridges 31 and second ridges 32 the same structure as the third ridges 33, the same effect as the third ridges 33 can be achieved.

[0042] Alternatively, for example, the apex 42a of the tapered shape of the cross section of the ridge body 40 may be located inward in the width direction of the tapered shape relative to both ends of the base 43a of the tapered shape, and one oblique side 44a and the other oblique side 45a may be inclined at the same gradient. In such a case, for example, the other inclined surface 45 of the ridge body 40 facing away from the crown 10 may be painted with a black glossy paint similar to the outer surface 16 of the visor 15, and the one inclined surface 44 of the ridge body 40 facing the crown 10 may be painted with a yellow matte paint different from the outer surface 16. In this way, if the headgear 1A is a baseball helmet, the third ridge 33 can be arranged on the outer surface 16 with the other inclined surface 45 facing away from the crown 10, resulting in a natural appearance. On the other hand, if the headgear 1A is a construction site helmet, the third ridge 33 can be arranged on the outer surface 16 with the one inclined surface 44 facing away from the crown 10, resulting in a natural appearance. That is, one third ridge 33 can be arranged on two types of headgear 1A without creating a sense of incongruity. Note that by making the first ridge 31 and the second ridge 32 have the same structure as the third ridge 33, the same effect as the third ridge 33 can be achieved.

[0043] In the above embodiment, the first to third ridges 31 to 33 have the same shape. However, this is not limiting, and the first to third ridges 31 to 33 may have different shapes. In such a case, at least one of the first to third ridges 31 to 33 may include a ridge body 40 having a protruding end.

[0044] In the above embodiment, the left-right central portion of the third ridge 33 is curved at a predetermined curvature in a convex shape toward the front (the side opposite the crown 10) when viewed from above. However, this is not limited to this, and the left-right central portion of the third ridge 33 may extend linearly in the left-right direction when viewed from above. This can prevent water droplets from accumulating in the left-right central portion of the third ridge 33. This can improve drainage efficiency.

[0045] In the above embodiment, the first to third ridges 31 to 33 are arranged on the headgear main body 2 so as to be line-symmetrical about the center line CL in the left-right direction when viewed from above. However, this is not limited to this, and at least one of the first to third ridges 31 to 33 may be arranged on the headgear main body 2 so as not to be line-symmetrical about the center line CL in the left-right direction when viewed from above. For example, if the headgear 1A is a baseball helmet for a right-handed batter, the arrangement of the first to third ridges 31 to 33 may be adjusted as needed to prevent water droplets from falling from the front end of the outer surface 16 of the visor 15, particularly from the center and right portions in the left-right direction. Similarly, if the headgear 1A is a baseball helmet for a left-handed batter, the arrangement of the first to third ridges 31 to 33 may be adjusted as needed to prevent water droplets from falling from the front end of the outer surface 16, particularly from the center and right portions in the left-right direction.

[0046] In the above embodiment, the case has been described where each of the ridge groups 3A, 3B includes one third ridge 33 between the first ridge 31 and the second ridge 32 in the front-rear direction. However, this is not limited to this case, and the ridge group may include multiple third ridges 33 between the first ridge 31 and the second ridge 32 in the front-rear direction.

[0047] In the above embodiment, the first ridges 31 and the third ridges 33 are curved with different curvatures when viewed from above. However, this is not limiting, and the first ridges 31 and the third ridges 33 may be curved with the same curvature when viewed from above.

[0048] In the above embodiment, a case has been described in which nothing is placed in the space defined by the outer surface 16 of the visor 15, the first ridges 31, and the third ridges 33, and the space defined by the outer surface 16, the second ridges 32, and the third ridges 33. However, this is not limiting, and a water-absorbent substance (for example, a sponge) may be placed to fill these spaces. This allows water droplets to be absorbed by the substance, further preventing water droplets from falling into the user's field of vision.

[0049] In the above embodiment, the headgear 1A, 1B are baseball helmets each equipped with a pair of earmuffs 20. However, the present invention is not limited to this, and the headgear 1A, 1B may each be a baseball helmet without a pair of earmuffs 20, or may each be a baseball helmet equipped with only one earmuff on either the left or right side. Alternatively, the headgear 1A, 1B may each be a helmet other than a baseball helmet, a cap, or other headgear.

[0050] In the above embodiment, a case has been described in which a glossy paint is applied to the outer surface of the headgear main body 2. However, this is not limited to this case, and the outer surface of the headgear main body 2 may not be painted, or may be subjected to a matte surface treatment.

[0051] In the above embodiment, the case where the ridge group 3 is sold separately from the headgear main body 2 has been described. However, this is not limited to this case, and the headgear 1A including the ridge group 3 may be sold with the ridge group 3 pre-arranged on the headgear main body 2. In this case, for example, the ridge group 3 and the headgear main body 2 may be integrated.

[0052] In the above embodiment, a headgear projection group 3 including first to third protrusions 31 to 33 has been described as being arranged on the headgear main body 2. However, this is not limited to this case, and headgear projection members having structures similar to those of the first to third protrusions 31 to 33 may be arranged on the headgear main body 2 in the same manner as those of the first to third protrusions 31 to 33. That is, the projection members may be the first to third protrusions 31 to 33 shown in FIGS. 1A to 2B. Each of the protrusion members 31 to 33 includes an elongated projection main body 40 having a bottom surface 43 and a protruding end 42 opposite the bottom surface 43, and an adhesive layer 41 provided on the bottom surface 43 of the projection main body 40 for attachment to the outer surface of the headgear 1A (the outer surface 16 of the visor 15 of the headgear main body 2). The cross section of the projection main body 40 has a tapered shape that narrows toward the protruding end 42. An apex 42a of the tapered shape is located outward in the width direction of the tapered shape from a base 43a of the tapered shape.

[0053] Each of the following aspects is a disclosure of a preferred embodiment. [Aspect 1] A group of ridges for a headgear, the headgear comprising: a crown that covers a user's head; and a visor connected to a front end of the crown, the crown including side crown portions that cover the sides of the head, the visor including an outer surface that extends downward from a center in the left-right direction of the visor outward in the left-right direction and facing upward, the group comprising: a first ridge that is arranged along a boundary between the outer surface of the crown and the outer surface of the visor and extends from the center in the left-right direction of the boundary to the side crown portions, a second ridge that is arranged along the front end of the outer surface of the visor and extends to the side crown portions, and a third ridge that is arranged between the first ridge and the second ridge in the front-to-rear direction on the outer surface of the visor when viewed from above and extends from the center in the left-to-right direction of the outer surface of the visor to the side crown portions. [Aspect 2] The group of ridges for a headgear according to Aspect 1, wherein the crown-side end of the third ridge is located between the crown-side end of the first ridge and the crown-side end of the second ridge in the up-down direction, and the end of the first ridge and the end of the second ridge are located on the same first imaginary line extending in the up-down direction.
