Description

head protection equipment

The present invention relates to head protection equipment, and more specifically, to head protection equipment with a structure that can reduce driving noise and eye irritation caused by the inflow of outside air.

Head protection equipment, commonly referred to as a helmet, is used to protect the wearer's head.

Helmets can be classified into half face, open face, and full face depending on the degree to which they cover the wearer's head. Among these, the most safe is the full-face type helmet, which covers most of the wearer's head, including the chin area.

However, in the case of full-face type helmets, the weight is considerable, and drivers often experience inconvenience, especially due to problems such as ventilation. Accordingly, recently, open face type helmets that combine the advantages of half face type and full face type have been in the spotlight.

While driving, outside air is blocked from entering the helmet by a visor provided on the helmet. However, in an open face type helmet, the lower part of the head, including the wearer's chin, is open. Accordingly, it is possible to prevent a situation where outside air flows in from the front, but it is difficult to prevent a situation where outside air enters the inside of the helmet through the lower side of the visor.

If outside air flows into the inside of the helmet, driving noise, which is noise generated by outside air while driving, may be transmitted directly to the wearer. Additionally, external air may flow into the wearer's eyes, making it difficult to secure vision. Therefore, situations may arise where people avoid wearing helmets, which are essential for safety.

Korean Patent Publication No. 10-2019-0014960 discloses a helmet. Specifically, a helmet is disclosed that includes an air purifying unit provided inside the helmet and can promote air circulation inside the helmet.

However, the helmet disclosed in the preceding literature only discloses a method for purifying the inflow of air, assuming that outside air has already flowed into the interior of the helmet. In other words, the prior literature does not suggest a method for preventing air from flowing into the interior of the helmet.

Korean Patent Publication No. 10-2017-0108413 discloses a type variable helmet. Specifically, a type variable helmet is disclosed that includes an underface unit that is detachably provided at the bottom of the half face unit and formed to surround the lower head area of the user.

However, the above prior literature only presents a method for changing the type of helmet itself. In other words, the purpose of the helmet disclosed in the above prior literature is to change a half-face type helmet into a full-face type helmet by attaching additional members. As a result, the prior literature does not disclose a method for preventing the inflow of external air while maintaining the half-face type.

Furthermore, the above prior literature does not disclose a method for adjusting air resistance or air inflow during driving by varying the area of the visor itself.

1 to 6, head protection equipment 10 according to an embodiment of the present invention is disclosed.

Head protection equipment 10 according to an embodiment of the present invention includes a main visor 200 and a sub-visor 300 to block external air flowing in from the front while driving. The subvisor 300 is configured to have a variable area exposed to the outside, so that the flow of outside air can be controlled.

With the above configuration, noise caused by external air during driving can be minimized. Additionally, the amount of air flowing into the inside of the head protection equipment 10 through one open side of the head protection equipment 10, the lower side in the illustrated embodiment, can be minimized. As a result, eye irritation that may occur when incoming air flows into the wearer's eyes can be minimized.

1 to 8, the head protection equipment 10 according to the illustrated embodiment includes an external frame 100, a main visor 200, a sub-visor 300, and a visor coupling member 400.

The external frame 100 forms the outline of the head protection equipment 10. A space is formed inside the external frame 100 to accommodate the wearer's head (head part). The external frame 100 can protect the wearer's head from external impacts, etc.

The external frame 100 may be shaped to accommodate and protect the wearer's head and minimize air resistance while driving. In the illustrated embodiment, the outer frame 100 is shaped like a sphere, similar to the wearer's head.

The main visor 200 is rotatably coupled to the external frame 100. Additionally, the sub-visor 300, which is rotatably coupled to the main visor 200, may also be said to be rotatably coupled.

A visor coupling member 400 may be coupled to the external frame 100. Specifically, the visor coupling member 400 is coupled to the main visor 200 and the sub-visor 300, respectively, so that the visor coupling member 400 is coupled to the external frame 100 by rotation of the main visor 200. can be separated.

In the illustrated embodiment, the external frame 100 includes a receiving space 110 .

The accommodation space 110 is a space formed inside the external frame 100. The receiving space 110 accommodates the wearer's head. The receiving space 110 is partially surrounded by the external frame 100. Another portion of the receiving space 110 is formed open. Some of the other parts of the accommodation space 110, the front side in the illustrated embodiment, are openably and closedly surrounded by the main visor 200 and the sub-visor 300.

Another part of the receiving space 110, the lower side in the illustrated embodiment, is formed open. The wearer can accommodate the wearer's head in a receiving space through the open lower portion. The portion of the other portion of the receiving space 110 may be covered or opened by the main visor 200 .

The main visor 200 is rotatably coupled to the outer frame 100 to open or close the portion of the other portion of the receiving space 110. During driving, the main visor 200 may close the portion of the other portion of the accommodation space 110 to prevent front air from flowing into the accommodation space 110 .

The main visor 200 is rotatably coupled to the external frame 100. In the illustrated embodiment, with respect to the right side, the main visor 200 may be rotated clockwise and moved upward to open the front side of the accommodation space 110.

In the illustrated embodiment, with respect to the right side, the main visor 200 may be rotated counterclockwise and moved downward. In this state, the main visor 200 may close the front side of the accommodation space 110.

The main visor 200 is combined with the sub-visor 300. The sub-visor 300 is rotatably coupled to the main visor 200, so that the area overlapping with the main visor 200 can be varied. Accordingly, the flow of outside air in the head protection equipment 10 can be controlled to minimize driving noise and the inflow of outside air.

3 to 4, the main visor 200 includes a main body 210, a main coupling groove 220, a main support protrusion 230, and a main support space 240.

The main body 210 forms the body of the main visor 200. The main body 210 may be formed in a shape corresponding to the open portion of the receiving space 110, or the front side in the illustrated embodiment. Additionally, the main body 210 may be formed in a shape corresponding to the shape of the external frame 100.

In the illustrated embodiment, the main body 210 is rounded to be convex toward the outside of the accommodation space 110 and extends along the vertical and left-right directions of the accommodation space 110. In other words, the horizontal cross-section of the main body 210 has an arc shape whose center is located in the receiving space 110 and extends in the width direction of the receiving space 110, that is, in the left and right directions. Accordingly, it will be understood that the main body 210 has a curved shape extending along both the height and width directions of the accommodation space 110.

The main body 210 extends to surround the receiving space 110. In the illustrated embodiment, the main body 210 extends surrounding the left and right portions and the front side of the receiving space 110 . The main body 210 is formed to have a predetermined height. That is, the main body 210 is formed to have a predetermined height along the rotation direction of the main visor 200, in the vertical direction in the illustrated embodiment.

In the illustrated embodiment, the main body 210 includes a first part 211 and a second part 212.

The first part 211 forms a part of the main body 210. The first part 211 independently covers a portion of the front side of the accommodation space 110 to prevent outside air from flowing into the accommodation space 110 through the front side during driving. In the illustrated embodiment, the first portion 211 forms the upper side of the main body 210.

The first portion 211 is rotatably coupled to the external frame 100 at an end, in the illustrated embodiment, at an end in the direction extending in the width direction, at a left end and at a right end, respectively. That is, in the embodiment shown in FIGS. 3 and 4, the inner surface of the first part 211 (i.e., the surface facing the receiving space 110) is provided with a coupling member rotatably coupled to the external frame 100. (Diagram not assigned) is provided.

The first part 211 may be formed to have a larger area than the second part 212. Accordingly, it can be said that the first part 211 mainly performs the role of preventing the inflow of external air located on the front side during driving.

The first part 211 is continuous with the second part 212.

The second portion 212 forms another portion of the main body 210 . The second part 212 covers another part of the front side of the accommodation space 110 to prevent outside air from flowing into the accommodation space 110 through the front side during driving. In the illustrated embodiment, the second portion 212 forms the lower side of the main body 210.

A subvisor 300 is rotatably coupled to an end of the second portion 212 in the width direction extending direction. Specifically, the sub-visor 300 is rotatably coupled to the second portion 212 by the visor coupling member 400. As the sub-visor 300 rotates, the second portion 212 may overlap the sub-visor 300.

The second part 212 may be formed to have a smaller area than the first part 211 . Additionally, the second part 212 may be formed to have a thickness smaller than that of the first part 211 . As will be described later, the subvisor 300 coupled to the second part 212 can be rotated to vary the area overlapping with the second part 212 (see FIGS. 7 and 8).

Due to the structure described above, the thickness of the second part 212 is formed to be smaller than that of the first part 211, thereby preventing excessive increase in the overall thickness of the main body 210.

Although reference numerals are not given, a protrusion may be formed adjacent to a portion where the first part 211 and the second part 212 are continuous. The protrusion may be inserted or extracted into a space formed between a pair of first sub protrusions 321 provided on the subvisor 300. In the above embodiment, the coupled state of the sub-visor 300 and the main visor 200 can be stably maintained.

The main coupling groove 220 is a portion where the main visor 200 is coupled to the visor coupling member 400. The main coupling groove 220 is recessed at a corner of the main body 210, so that the main coupling protrusion 410 provided on the visor coupling member 400 can be inserted.

The main coupling groove 220 may be formed at a corner of the main body 210 facing the visor coupling member 400. In the embodiment shown in FIG. 4, the main coupling groove 220 is located at a corner facing the visor coupling member 400 among the ends in the width direction, that is, at the rear lower edge.

The main coupling groove 220 may be formed in a plurality of positions. The plurality of main coupling grooves 220 may each be coupled to different visor coupling members 400. In the illustrated embodiment, the main engaging groove 220 is located at the left and right ends of the rear lower side of the main body 210, respectively.

The main coupling groove 220 may be formed in a shape corresponding to the shape of the main coupling protrusion 410. In the illustrated embodiment, the main coupling groove 220 is formed in a straight line and depressed for a predetermined length.

In the illustrated embodiment, the main coupling groove 220 includes a first main coupling groove 221 and a second main coupling groove 222.

The first main coupling groove 221 receives one main coupling protrusion 410 among the plurality of main coupling protrusions 410 in a withdrawable manner. The first main coupling groove 221 is recessed in one edge of the rear lower edge of the main body 210 that extends obliquely in the vertical direction.

The second main coupling groove 222 is located adjacent to the first main coupling groove 221.

The second main coupling groove 222 retractably receives another main coupling protrusion 410 among the plurality of main coupling protrusions 410 . The second main coupling groove 222 is recessed in another edge of the rear lower edge of the main body 210 that extends obliquely in the front-back direction.

The directions in which the first main coupling groove 221 and the second main coupling groove 222 are depressed may be formed differently. Accordingly, the main visor 200 and the visor coupling member 400 are supported and coupled in different directions, so that the coupling state between the main visor 200 and the visor coupling member 400 can be stably maintained.

Although reference numerals are not given, a main coupling hole may be provided at the end of the second part 212 of the main body 210, adjacent to the main coupling groove 220. The sub-coupling protrusion 420 of the visor coupling member 400 may be rotatably coupled to the main coupling ball (reference symbol not given). Accordingly, the main visor 200 can rotatably support the sub-visor 300.

The main support protrusion 230 limits the rotation distance of the sub-visor 300 rotatably coupled to the main visor 200. The rotation distance in the direction in which the sub-visor 300 is spaced apart from the main visor 200 may be limited by the main support protrusion 230 .

The main support protrusion 230 is formed on the second portion 212 of the main body 210. The main support protrusion 230 is formed to protrude toward the subvisor 300 on one side of the second portion 212 facing the receiving space 110, or in the illustrated embodiment, on the rear side.

The main support protrusion 230 is located at the end of the main body 210 in the height direction. In the illustrated embodiment, the main support protrusion 230 is located at one end in the height direction of the second portion 212, that is, at the lower end. In other words, the main support protrusion 230 is located at one end opposite to the first portion 211.

The main support protrusion 230 may be located at each end of the subvisor 300 in the height direction, between the upper end and the lower end in the illustrated embodiment. As the sub-visor 300 rotates, the main support protrusion 230 may be positioned adjacent to or spaced apart from the sub-protrusion 320.

The main support protrusion 230 extends along the direction in which the second portion 212 extends, in the left and right directions in the illustrated embodiment. As described above, the main body 210 on which the second part 212 is formed is formed as a curved surface with an arc-shaped cross-section, and the main support protrusion 230 may also have an arc-shaped cross-section. You will understand.

The main support protrusion 230 may be located adjacent to either the first sub protrusion 321 or the second sub protrusion 322 of the sub visor 300. As the subvisor 300 rotates, the main support protrusion 230 moves into the space formed between the pair of first sub protrusions 321 or between the second sub protrusion 322 and the gripping protrusion 340. It can be inserted or extracted into space.

That is, referring to FIGS. 7 and 8, at the first position P1, that is, in a state where the area where the subvisor 300 is exposed to the outside is minimal, the main support protrusion 230 is positioned at the second sub protrusion 322. It can be located adjacent to . In this state, the main support protrusion 230 is inserted into the space formed between the second sub protrusion 322 and the grip protrusion 340.

Additionally, in the second position P2, that is, in a state where the area exposed to the outside of the sub-visor 300 is maximized, the main support protrusion 230 may be positioned adjacent to the first sub-protrusion 321. In this state, the main support protrusion 230 is inserted into the space formed between the pair of first sub protrusions 321.

In particular, at the second position P2, the main support protrusion 230 supports the first sub protrusion 321 located on the upper side of the pair of first sub protrusions 321, thereby rotating the sub visor 300. The distance is limited, and arbitrary departure of the subvisor 300 can be prevented.

The main support space 240 is a space formed between the second part 212 of the main body 210 and the subvisor 300. In other words, the main support space 240 is the side of the second part 212 facing the receiving space 110, that is, the space formed between each end of the inner surface in the height direction of the second part 212. can be defined.

The main support space 240 may be defined as a space in which the sub protrusion 320 of the sub visor 300 moves. The sub protrusion 320 may be rotated together with the sub visor 300 to move in the direction in which the main support space 240 extends, in the up and down direction in the illustrated embodiment.

At the first position P1, the main support space 240 may be partially surrounded by the sub body 310 of the sub visor 300. That is, in the embodiment shown in FIGS. 7 and 8, the front side of the main support space 240 is surrounded by the inner side of the second part 212, and the rear side is surrounded by the front side of the sub-body 310.

Accordingly, it can be said that the inner surface of the second part 212 and the front surface of the sub-body 310 are spaced apart from each other with the main support space 240 in between.

In the second position P2, the main support space 240 communicates with the accommodation space 110 and its lower side may be partially surrounded by the sub-body 310.

Referring again to FIGS. 1 to 3, head protection equipment 10 according to an embodiment of the present invention includes a subvisor 300.

The sub-visor 300 is rotatably coupled to the main visor 200 and is configured to vary the area that blocks external air on the front side during driving. In other words, the subvisor 300 serves to expand the function of the main visor 200.

The sub-visor 300 may be formed to have a smaller surface area than the main visor 200. The sub-visor 300 may be arranged so that part or all of it covers (or overlaps) the main visor 200 .

The sub-visor 300 may be rotated between a first position (P1) accommodated in the second part 212 of the main visor 200 and a second position (P2) exposed in the second part 212 (Figure 7 to 8). Accordingly, the first position (P1) will be defined as a state in which the area exposed to the outside of the subvisor 300 is minimal, and the second position (P2) will be defined as a state in which the area exposed to the outside of the subvisor 300 is maximized. You will be able to.

The sub-visor 300 is rotatably coupled to the main visor 200. Specifically, the sub-visor 300 is rotatably coupled to the main visor 200 via the visor coupling member 400.

In the illustrated embodiment, with respect to the right side, the subvisor 300 may be rotated clockwise and moved upward. The state may be defined as the first position P1 where the area where the subvisor 300 is exposed to the outside is minimal. Accordingly, it will be understood that at the first position P1, the overlapping area between the sub-visor 300 and the main visor 200 is maximized.

Additionally, in the illustrated embodiment, with respect to the right side, the subvisor 300 may be rotated counterclockwise and moved downward. The state may be defined as the second position P2 where the area where the subvisor 300 is exposed to the outside is maximum. Accordingly, it will be understood that at the second position P2, the overlapping area between the sub-visor 300 and the main visor 200 is minimal. That is, the area covered by the main visor 200 or the sub-visor 300 of the accommodation space 110 can be adjusted by rotating the sub-visor 300.

In the embodiment shown in FIG. 5 , the sub visor 300 includes a sub body 310, a sub protrusion 320, a sub coupling portion 330, and a grip protrusion 340.

The sub body 310 forms the body of the sub visor 300. The sub-body 310 may be formed in a shape corresponding to the open portion of the receiving space 110, or, in the illustrated embodiment, the front side. Additionally, the sub-body 310 may be formed in a shape corresponding to the shape of the external frame 100.

In the illustrated embodiment, the sub-body 310 is rounded to be convex toward the outside of the accommodation space 110 and extends along the vertical and left-right directions of the accommodation space 110. The sub body 310 is formed to have a predetermined height. That is, the sub-body 310 is formed to have a predetermined height along the rotation direction of the sub-visor 300, in the vertical direction in the illustrated embodiment.

In other words, the horizontal cross-section of the sub-body 310 has an arc shape whose center is located in the accommodation space 110 and extends in the width direction of the accommodation space 110, that is, in the left and right directions. At this time, the sub-body 310 is formed so that the height direction, that is, the width in the vertical direction, of the accommodation space 110 is reduced along the direction toward the ends in the extending direction, that is, the ends in the left and right directions. Accordingly, it will be understood that the sub-body 310 has a curved shape extending along both the height and width directions of the accommodation space 110.

At this time, the height of the sub body 310 may be less than or equal to the height of the second part 212 of the main visor 200. Accordingly, at the first position P1, the sub-body 310 overlaps the second portion 212 and the area exposed to the outside can be minimized.

The sub protrusion 320 is coupled to or spaced apart from the main support protrusion 230 of the main visor 200 as the sub visor 300 rotates. Due to the combination and separation, the rotation distance of the subvisor 300 may be limited.

The sub protrusion 320 is formed on the sub body 310. Specifically, the sub protrusion 320 is formed to protrude from one side of the sub body 310 facing the second portion 212 of the main visor 200, or, in the illustrated embodiment, from the front side.

The sub protrusion 320 may extend a predetermined length in the width direction of the sub body 310, in the left and right directions in the illustrated embodiment. Accordingly, the sub protrusion 320 is formed to have an arc-shaped cross section whose center is located in the receiving space 110.

A plurality of sub protrusions 320 may be formed. The plurality of sub protrusions 320 may be arranged to be spaced apart from each other along the height direction of the sub body 310, that is, in the vertical direction in the illustrated embodiment. At the first position P1, one sub protrusion 320 among the plurality of sub protrusions 320 may be positioned adjacent to the main support protrusion 230. At the second position P2, another sub protrusion 320 of the plurality of sub protrusions 320 may be positioned adjacent to the main support protrusion 230.

The sub protrusion 320 may contact or be spaced apart from the main support protrusion 230 as the sub visor 300 moves. As will be described later, a plurality of sub protrusions 320 may be provided, and as the sub visor 300 moves, any one of the plurality of sub protrusions 320 may be moved to the main support protrusion 230. ) It will be understood that it is separated from.

In the illustrated embodiment, the sub protrusion 320 includes a first sub protrusion 321 located at one end in the height direction of the sub body 310, that is, the upper end, and a second sub protrusion 321 located at the other end, that is, the lower end. Includes protrusions 322.

The first sub protrusion 321 is located on the upper side of the sub body 310 and is spaced apart from the main support protrusion 230 at the first position P1. Additionally, when the sub visor 300 is rotated downward to form the second position P2, the first sub protrusion 321 comes into contact with the main support protrusion 230. Accordingly, the downward movement distance of the subvisor 300 is limited. As a result, the area of the sub-visor 300 exposed to the outside of the main visor 200 may be limited.

A plurality of first sub protrusions 321 may be formed. The plurality of first sub-protrusions 321 may be spaced apart from each other, and a space may be formed between them. In the illustrated embodiment, a pair of first sub protrusions 321 are provided, and the pair of first sub protrusions 321 are arranged to be spaced apart from each other along the height direction, that is, the vertical direction, of the sub body 310.

At the second position P2, the main support protrusion 230 is inserted into the space formed between the pair of first sub protrusions 321. Accordingly, further movement downward of the subvisor 300 may be restricted.

The second sub protrusion 322 is located on the lower side of the sub body 310 and comes into contact with the main support protrusion 230 at the first position P1. Accordingly, the upward movement distance of the subvisor 300 is limited. As a result, the area where the sub-visor 300 overlaps the main visor 200 may be limited. Additionally, when the sub-visor 300 is rotated downward to form the second position P2, the second sub-protrusion 322 is spaced apart from the main support protrusion 230 and is exposed to the outside of the main visor 200.

The second sub protrusion 322 is disposed adjacent to the gripping protrusion 340. At this time, the second sub protrusion 322 is spaced apart from the gripping protrusion 340 by a predetermined distance, and a space is formed between them. At the first position P1, the main support protrusion 230 may be inserted into the space.

At this time, the above-described first sub-protrusion 321 and second sub-protrusion 322 may partially overlap with the main support protrusion 230 along the moving direction of the sub-visor 300. Accordingly, contact and separation between the first sub-protrusion 321 and the second sub-protrusion 322 and the main support protrusion 230 may be performed in the form of fitting and removal.

As a result, unless the wearer applies an external force of a predetermined size or greater, the first sub-protrusion 321 and the second sub-protrusion 322 are not arbitrarily spaced apart from the main support protrusion 230. Accordingly, the relative positions of the sub-visor 300 and the main visor 200 can be maintained stably.

The sub-coupling portion 330 is a portion where the sub-visor 300 is coupled to the main visor 200 through the visor coupling member 400 and the visor coupling member 400.

The sub-coupling portion 330 may be formed at a corner of the sub-body 310 facing the visor coupling member 400. In the embodiment shown in Figure 5, the sub-coupling portion 330 is located adjacent to the end in the width direction. In other words, the sub-coupling portion 330 is located adjacent to one end facing the visor coupling member 400.

A plurality of sub-coupling portions 330 may be formed. Each of the plurality of sub-coupling parts 330 may be coupled to a different visor coupling member 400. In the illustrated embodiment, the sub-coupling portion 330 is located at the left end and right end of the sub body 310, respectively.

In the illustrated embodiment, the sub-coupling portion 330 includes a sub-edge 331 and a sub-coupling hole 332.

Sub-edge 331 forms part of the edge of sub-body 310. The sub-edge 331 may be defined as an edge facing the limiting edge 430 of the visor coupling member 400. The sub edge 331 contacts or is spaced apart from the limiting edge 430 of the visor coupling member 400 as the sub visor 300 rotates.

Specifically, at the first position P1, the sub edge 331 is spaced apart from the limiting edge 430. At the second position P2, the sub edge 331 is in contact with the limit edge 430. As will be described later, the visor coupling member 400 and the main visor 200 are coupled such that relative movement is limited.

Accordingly, as the sub-visor 300 is rotated relative to the main visor 200, the sub-visor 300 is also rotated relative to the visor coupling member 400. At this time, the sub edge 331 may be in contact with the limiting edge 430, thereby limiting the rotation distance or rotation angle of the sub visor 300.

The sub coupling hole 332 is a portion where the sub visor 300 is rotatably coupled to the visor coupling member 400. The sub-coupling hole 332 is formed through the sub-body 310 so that the sub-coupling protrusion 420 of the visor coupling member 400 can be coupled thereto.

The sub-coupling hole 332 may be any structure capable of rotatably coupling the sub-visor 300 and the visor coupling member 400. In the illustrated embodiment, the sub-coupling hole 332 is formed to have a circular cross-section.

The grip protrusion 340 is a part that is exposed to the outside and manipulated by the wearer. The grip protrusion 340 is exposed to the outside of the main visor 200 regardless of the first position (P1) or the second position (P2). Accordingly, the wearer can rotate the sub-visor 300 regardless of the position of the sub-visor 300.

The grip protrusion 340 is continuous with the other end in the height direction of the sub-body 310, in the illustrated embodiment, the lower end. In other words, the gripping protrusion 340 forms the lower end of the subvisor 300.

The gripping protrusion 340 extends obliquely at a predetermined angle with the sub-body 310. Specifically, the grip protrusion 340 extends obliquely along the direction in which the sub-body 310 extends, in the illustrated embodiment, the vertical direction. That is, with further reference to FIGS. 7 and 8 , the grip protrusion 340 extends obliquely toward the front lower side. In other words, the gripping protrusion 340 extends from one end in the height direction of the sub-body 310, in the illustrated embodiment, from the lower end, away from the main supporting protrusion 230.

At this time, one end of the grip protrusion 340 in the extension direction may be disposed to protrude compared to the other side of the main body 210 opposite to the receiving space 110, or, in the illustrated embodiment, the front side. Accordingly, the wearer can easily recognize the position of the gripping protrusion 340 through the sense of touch without visual identification, and rotate the subvisor 300 by manipulating the gripping protrusion 340.

As will be described later, at the first position P1, the other end of the grip protrusion 340 in the extending direction may be in contact with the main support protrusion 230. Due to the contact, the movement distance in the direction in which the sub-visor 300 overlaps the main visor 200 may be limited.

The gripping protrusion 340 and the second sub protrusion 322 are spaced apart from each other, and a space is formed between them. At the first position P1, the main support protrusion 230 may be inserted into the space formed between the grip protrusion 340 and the second sub protrusion 322.

Referring again to FIG. 3, head protection equipment 10 according to an embodiment of the present invention includes a visor coupling member 400.

The visor coupling member 400 rotatably supports the sub-visor 300. Additionally, the visor coupling member 400 is coupled to the main visor 200. Accordingly, it can be said that the visor coupling member 400 rotatably couples the sub-visor 300 to the main visor 200.

The visor coupling member 400 is coupled to the main visor 200. Specifically, the visor coupling member 400 is inserted and coupled to the main coupling groove 220 of the main visor 200. As described above, the main coupling groove 220 includes a first main coupling groove 221 and a second main coupling groove 222 extending in different directions. Accordingly, the visor coupling member 400 and the main visor 200 may be coupled with limited relative rotation.

The visor coupling member 400 is coupled to the sub-visor 300. Specifically, the visor coupling member 400 is rotatably coupled to the sub coupling portion 330 of the sub visor 300. At this time, as described above, the rotation distance of the sub-visor 300 is limited by the visor coupling member 400.

A plurality of visor coupling members 400 may be provided. The plurality of visor coupling members 400 may be respectively coupled to the plurality of main coupling grooves 220 and sub coupling portions 330. In the illustrated embodiment, two visor coupling members 400 are provided and are coupled to the main coupling groove 220 and the sub coupling portion 330 located on the left and right sides, respectively.

In the illustrated embodiment, the visor coupling member 400 is shown to be separately provided and coupled to the main visor 200. Alternatively, the visor coupling member 400 may be formed coupled to the main visor 200. That is, the visor coupling member 400 may be formed integrally with the main visor 200.

In the embodiment shown in FIG. 6 , the visor engaging member 400 includes a main engaging protrusion 410, a sub engaging protrusion 420, and a limiting edge 430.

The main coupling protrusion 410 is a portion where the visor coupling member 400 is coupled to the main visor 200. The main coupling protrusion 410 is formed to protrude inward in the direction toward the main visor 200, in the illustrated embodiment.

The main coupling protrusion 410 is coupled to the main coupling groove 220. Specifically, the main coupling protrusion 410 is inserted and coupled to the main coupling groove 220. To this end, the main coupling protrusion 410 may be formed in a shape corresponding to the main coupling groove 220.

As described above, the main coupling groove 220 extends obliquely with respect to the edge of the main body 210, and the main coupling protrusion 410 may also extend obliquely along the extension direction of the main coupling groove 220.

A plurality of main coupling protrusions 410 may be provided. The plurality of main coupling protrusions 410 may extend in different directions, be spaced apart from each other, and be coupled to the plurality of main coupling grooves 220, respectively. In the illustrated embodiment, two main coupling grooves 220 are provided, and are inserted and coupled to the first main coupling groove 221 and the second main coupling groove 222, respectively.

The sub-coupling protrusion 420 is a portion where the sub-visor 300 is rotatably coupled to the visor coupling member 400. The sub-coupling protrusion 420 is formed to protrude inward toward the sub-visor 300, in the illustrated embodiment.

The sub-coupling protrusion 420 is coupled to the sub-coupling hole 332. Specifically, the sub-coupling protrusion 420 is coupled through the sub-coupling hole 332. The sub-coupling protrusion 420 may be formed in a shape corresponding to the sub-coupling hole 332. In the illustrated embodiment, the sub-coupling protrusion 420 has the same shape as the sub-coupling hole 332, that is, a cylindrical shape with a circular cross-section and extending toward the sub-visor 300.

The sub-coupling protrusion 420 is coupled to the main coupling hole (reference numeral not assigned) described above. At this time, as described above, the main coupling protrusion 410 is coupled to the main coupling groove 220, so that relative rotation of the visor coupling member 400 and the main visor 200 can be prevented. Accordingly, the sub-coupling protrusion 420 is relatively fixed to the main visor 200 and can rotatably support the sub-visor 300.

The limit edge 430 is in contact with or spaced apart from the sub edge 331 as the sub visor 300 rotates. Due to the contact between the limit edge 430 and the sub-edge 331, the downward rotation distance or rotation angle of the sub-visor 300 may be limited.

Limiting edge 430 forms one edge of visor coupling member 400. That is, in the embodiment shown in FIG. 6, the limiting edge 430 forms an edge facing the sub-edge 331 of the sub-visor 300.

The limiting edge 430 may extend obliquely. Specifically, the limiting edge 430 may extend parallel to the sub edge 331 when the sub visor 300 is rotated to the second position P2. Accordingly, the limiting edge 430 can stably support the sub-edge 331 and limit the rotation distance of the sub-visor 300.

Hereinafter, the operation process of the head protection equipment 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. 7 and 8.

Referring to FIG. 7, the subvisor 300 is shown positioned at the first position P1. At the first position P1, the area of the subvisor 300 exposed to the outside is minimal. Accordingly, the area where the sub-visor 300 overlaps the main visor 200, specifically the second portion 212, at the first position P1 is maximized.

Referring to the enlarged view of FIG. 7, the upper first sub protrusion 321 is spaced apart from the main support protrusion 230 and is located adjacent to the upper end of the second portion 212. In addition, the main support protrusion 230 is fitted into the space formed between the lower second sub protrusion 322 and the grip protrusion 340.

In the above state, the sub edge 331 and the limiting edge 430 are spaced apart from each other, so that there is a clearance that allows the sub visor 300 to be moved in the direction opposite to the main visor 200, that is, downward in the illustrated embodiment. formation will be understood.

Referring to FIG. 8, the subvisor 300 is shown positioned at the second position (P2). At the second position P2, the area of the subvisor 300 exposed to the outside is maximized. Accordingly, the area where the sub-visor 300 overlaps the main visor 200, specifically the second portion 212, at the second position P2 is minimized.

Referring to the enlarged view of FIG. 8, the upper first sub protrusion 321 is located adjacent to the main support protrusion 230. As described above, in an embodiment in which a pair of first sub protrusions 321 are provided, the main support protrusion 230 is fitted into a space formed by the pair of first sub protrusions 321 spaced apart from each other.

In this state, the sub edge 331 and the limiting edge 430 are in contact with each other, preventing the sub visor 300 from moving further downward.

Hereinafter, with reference to FIGS. 9 and 10, the flow F of external air formed by the head protection equipment 10 according to an embodiment of the present invention will be described in detail.

Referring to FIG. 9, the subvisor 300 is shown positioned at the first position P1. At the first position P1, the exposed area of the sub-visor 300 is minimized, and most of the outside air flows after colliding with the main visor 200.

At the first position P1, the flow F of outdoor air in the lower portions of the main visor 200 and the sub-visor 300 is described as follows.

The outdoor air on the front side flows downward along the main visor 200. At this time, the subvisor 300 is located at the first position (P1), so the area exposed to the outside is minimized.

The flow F of the outside air passes through the grip protrusion 340 located at the lower end of the subvisor 300 and proceeds toward the rear. Some of the flow (F) of the outside air passing through the subvisor 300 proceeds toward the rear and upper side.

At this time, since the grip protrusion 340 is located adjacent to the main visor 200, a portion of the flow F of the outside air flows to the lower side where the receiving space 110 is opened.

Accordingly, some of the outside air may flow into the receiving space 110, causing driving noise. Furthermore, some of the external air flowing into the receiving space 110 may flow into the wearer's eyes, causing eye irritation.

Referring to FIG. 10 , the subvisor 300 is shown positioned at the second position P2. At the second position P2, the exposed area of the sub-visor 300 is maximized, and a portion of the outdoor air flows after colliding with the main visor 200 and the other portion of the outdoor air collides with the sub-visor 300.

At the second position P2, the flow F of outdoor air in the lower portions of the main visor 200 and the sub-visor 300 is described as follows.

The outdoor air on the front side flows downward along the main visor 200. At this time, the subvisor 300 is located at the second position (P2), so the area exposed to the outside is maximized.

At this time, the grip protrusion 340 is positioned to be spaced apart from the main visor 200 as much as possible. Accordingly, the distance that must travel for the portion of the flow F of outside air to extend into the receiving space 110 increases. As the distance increases, the resistance to the flow F of the outside air moving toward the receiving space 110 increases, so that most of the outside air does not enter the receiving space 110.

As a result, the amount of outside air flowing into the receiving space 110 can be minimized, thereby minimizing driving noise and eye irritation caused by the inflow of outside air.

As described above, the head protection equipment 10 according to an embodiment of the present invention includes a main visor 200 and a sub-visor 300 rotatably coupled to the main visor 200. The sub-visor 300 may be arranged to overlap the main visor 200 by external manipulation, or may be arranged to be exposed from the main visor 200 so that the overall area of the visor can be varied.

When the sub-visor 300 is maintained at the second position (P2), that is, the area exposed to the outside is maximized, the outdoor air flowing upward among the outdoor air flowing toward the rear along the main visor 200 and the sub-visor 300 The flow rate can be minimized.

Accordingly, the amount of outdoor air flowing into the interior of the head protection equipment 10, that is, the receiving space 110, can also be minimized, and the driving noise generated by the introduced outdoor air can be minimized. In addition, the amount of external air flowing into the user's eyes is also minimized, preventing eye irritation.

As the sub-visor 300 is rotatably coupled to the main visor 200, the overall area of the main visor 200 and the sub-visor 300 can be changed even if no additional member is provided.

The gripping protrusion 340 provided at the lower end of the sub-visor 300 is exposed to the outside of the main visor 200. The wearer can easily change the overall area of the visor by rotating the grip protrusion 340.

The sub-visor 300 is rotatably coupled to the main visor 200 by the sub-coupling protrusion 420 of the visor coupling member 400. Additionally, the rotation distance or rotation angle of the sub-visor 300 is limited by the main support protrusion 230 of the main visor 200 and the limiting edge 430 of the visor coupling member 400. Furthermore, the subvisor 300 may be combined with the main support protrusion 230 or supported on the limiting edge 430 and maintained in a rotated position.

Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention can add or change components within the scope of the same spirit. , deletion, addition, etc., other embodiments can be easily proposed, but this will also be said to be within the scope of the present invention.
