In addition, FIG. 2 is a perspective view of the open state of a visor of a helmet according to one embodiment of the present invention. Meanwhile, FIG. 3 is a side view showing the open state of a visor of a helmet according to one embodiment of the present invention.

[0025] Referring to FIGS. 1 to 3, a helmet 100 according to one embodiment of the present invention may include a helmet body 110, a visor 120 and a holder 130.

[0026] The helmet body 110 is disposed to cover the user's head. The helmet body 110 forms a basic skeleton of the helmet 100 according to one embodiment of the present invention. The helmet body 110 may be made of a material capable of absorbing shock.

[0027] For example, the helmet body 110 may include an outer shell formed of a hard synthetic resin or the like and having high strength, and a shock absorber provided inside the outer shell. In this case, the shock absorber may be formed of expanded polystyrene (EPS) or the like.

[0028] The helmet body 110 has a face opening portion 111. The face opening portion 111 is formed at the front of the helmet body 110. The face opening portion 111 secures a field of vision for a user wearing the helmet 100. The face opening portion 111 may be closed or opened by a visor 120.

[0029] The helmet body 110 may have a slot 112 into which a hook 122 of the visor 120 is inserted when the visor 120 is in a position to close the face opening portion 111. In one embodiment of the present invention, a pair of slots 112 are provided, one each on one front side and the other front side of the helmet body 110.

[0030] The visor 120 is pivotally coupled to the helmet body 110 such that the face opening portion 111 can be opened or closed. While the visor 120 is disposed to close the face opening portion 111, it blocks wind, foreign substances and the like from reaching the face of a user wearing the helmet 100.

[0031] In one embodiment of the present invention, the visor 120 may be coupled to the helmet body 110 at one side part and the other side part. In this case, the one side part and the other side part of the visor 120 coupled to the helmet body 110 may function as a pivot axis.

[0032] The visor 120 may include a visor body 121 formed to close or open the face opening portion 111 and a hook 122 provided at the bottom of the visor body 121.

[0033] The visor body 121 may have a curved shape. The visor body 121 may have a left-right symmetrical shape. In addition, the visor body 121 may be made of a transparent or translucent material.

[0034] The hook 122 may be provided at the bottom of the visor body 121. The hook 122 secures the visor 120 such that the visor 120 can maintain a state in which the face opening portion 111 is closed while being fastened to a holder 130 described below.

[0035] In one embodiment of the present invention, the hook 122 may be formed by recessing the visor body 121. More specifically, a pair of hooks 122 may be provided, one each on the lower side of one side and the other side of the visor body 121.

[0036] The holder 130 is disposed on the helmet body 110 such that the hook 122 can be fastened to the outer surface. In one embodiment of the present invention, the holder 130 may be disposed transversely across an inside of the slot 112. In addition, at least one of one end and the other end in the longitudinal direction of the holder 130 may be fixed to a wall of the helmet body 110 forming the slot 112.

[0037] The holder 130 is fastened to the hook 122 to secure the visor 120. In addition, the holder 130 causes a predetermined threshold force to be generated when the visor 120 is opened or closed. That is, a predetermined threshold force is required when the hook 122 is fastened to the holder 130 or when the hook 122 is separated from the holder 130.

[0038] The holder 130 may have a rod shape. More specifically, the holder 130 may have a cylindrical shape. In this case, the hook 122 may be disposed to surround a part of an outer surface of the holder 130 so as to have a certain level or more of resistance to a force acting in the opening direction of the visor 120 while being fastened to the holder 130.

[0039] FIG. 4 is a cross-sectional view of a helmet holder according to one embodiment of the present invention. Referring to FIG. 4, in one embodiment of the present invention, the holder 130 may include a core member 131 and a tube 132.

[0040] The core member 131 may have a cylindrical shape. In addition, at least one of one end and the other end in the longitudinal direction of the core member 131 may be fixed to a wall of the helmet body 110 forming a slot 112.

[0041] The tube 132 is disposed to fit onto the outer surface of the core member 131. In other words, the tube 132 is disposed to surround an outer surface of the core member 131. The tube 132 may rotate with respect to the core member 131 when the hook 122 is fastened to or separated from the holder 130.

[0042] FIG. 5 is a drawing showing the rotation of a tube when a visor of a helmet according to one embodiment of the present invention is fastened to a holder.

[0043] Referring to FIG. 5, when the visor 120 pivots in a closing direction to close the face opening portion 111 of the helmet body 110, the hook 122 moves from the front lower side to the rear upper side of the helmet 100 and comes into contact with the tube 132 of the holder 130.

[0044] In this case, the tube 132 may be rotated in a first direction by the hook 122. Here, the first direction may be a counterclockwise direction when the helmet 100 is viewed from the left, and a clockwise direction when the helmet 100 is viewed from the right.

[0045] In this way, when the hook 122 pivots in the closing direction and comes into contact with the tube 132, the threshold force required for the process of fastening the hook 122 to the holder 130 may be lowered by rotating the tube 132 in the first direction. Accordingly, the hook 122 may be smoothly fastened to the holder 130.

[0046] FIG. 6 is a drawing showing the rotation of a tube when the visor of a helmet according to one embodiment of the present invention is separated from the holder.

[0047] Referring to FIG. 6, when the visor 120 pivots in the opening direction to open the face opening portion 111 of the helmet body 110, the hook 122 moves from the rear upper side to the front lower side of the helmet 100 and presses the tube 132 of the holder 130.

[0048] In this case, the tube 132 may be rotated in a second direction opposite to the first direction by the hook 122. Here, the second direction may be a clockwise direction when the helmet 100 is viewed from the left, and a counterclockwise direction when the helmet 100 is viewed from the right.

[0049] In this way, when the hook 122 pivots in the opening direction and comes into contact with the tube 132, the threshold force required for the process of separating the hook 122 from the holder 130 may be lowered by rotating the tube 132 in the second direction. Accordingly, the hook 122 may be smoothly separated from the holder 130.

[0050] As described above, the holder 130 is fitted onto the outer surface of the core member 131 and may reduce a force required in the initial stage of opening and the final stage of closing of the visor 120 through the tube 132 that is rotatable relative to the core member 131. In other words, the helmet 100 according to one embodiment of the present invention may provide a smooth usage feeling during the opening and closing process of the visor 120 through the tube 132.

[0051] Meanwhile, a lubricant may be applied between the inner surface of the tube 132 and the core member 131 to reduce friction and improve durability.

[0052] FIG. 7 is a drawing showing the arrangement of a pivot axis and holder of a visor when the visor of a helmet is closed according to one embodiment of the present invention.

[0053] Referring to FIG. 7, while the visor 120 is fastened to the holder 130, among two points at which a line passing through a pivot axis C1 of the visor 120 and a center C2 of the holder 130 intersects the holder 130, a point that is furthest from the pivot axis C1 may be defined as a center point P.

[0054] When the center point P is defined as above, a tangent line L1 of the holder 130 passing through the center point P and a straight line passing through an end of the hook 122 and the center point P may form a predetermined angle A. The predetermined angle A may be -10 degrees or more and 60 degrees or less.

[0055] The angle A may be determined by the position of the end of the hook 122. In addition, the negativity and positivity of the angle may be defined such that when the end of the hook is positioned on the front side of the helmet 100 compared to the tangent line L1 of the holder 130 passing through the center point P, it appears as negative, and when it is positioned on the rear side of the helmet 100, it appears as positive.

[0056] In one embodiment of the present invention, a straight line L2 passing through the end P2 of the hook 122 and the center point P may be disposed to form an angle of 60 degrees with a tangent line L1 of the holder 130 passing through the center point P.

[0057] As a result of the kinematic analysis, it was found that when the straight line L2 passing through the end P2 and the center point P of the hook 122 is disposed at an angle greater than 60 degrees with the tangent line L1 of the holder 130, the hook 122 must be excessively deformed when fastening or detaching the hook 122 to or from the holder 130, which reduces usability.

[0058] In addition, the end of the hook 122 may be disposed on a straight line L3 passing through the center point P and forming an angle of -10 degrees with the tangent line L1 of the holder 130 passing through the center point P.

[0059] As a result of the kinematic analysis, it was confirmed that when the straight line passing through the end of the hook 122 and the center point P is disposed so as to form an angle less than -10 degrees with the tangent line L1 of the holder 130 passing through the center point P, the fastening stability between the hook 122 and the holder 130 is not sufficiently secured.

[0060] Considering the above points, it is preferable that the end of the hook 122 be disposed on an arbitrary straight line passing through the center point P and forming an angle between -10 degrees and 60 degrees with the tangent line L1 of the holder 130 passing through the center point P.

[0061] When the end of the hook 122 is disposed within this range, the fastening stability between the hook 122 and the holder 130, the usability during the fastening or separating process of the hook 122 and the holder 130 and the like may be appropriately secured.

[0062] Meanwhile, the relationship between the hook 122 and the holder 130 may also be explained from the following perspective.

[0063] The hook 122 may be arranged to surround the holder 130 by 142 degrees or more based on a center C2 of the holder 130 when it is fastened to the holder 130. When the end P2 of the hook 122 is disposed on a straight line L3 passing through the center point P and forms an angle of -10 degrees with the tangent line L1 of the holder 130 passing through the center point P, it was confirmed that the hook 122 surrounds the holder 130 by 142 degrees based on the center C2 of the holder 130 when it is fastened to the holder 130.

[0064] Here, an angle B at which the hook 122 surrounds the holder 130 may be defined as an angle formed by a point P1 at which contact with the holder 130 begins at the upper part of the hook 122 based on the center of the holder 130 and the end P2 of the hook 122.

[0065] If the hook 122 is disposed to contact the holder 130 at an angle of less than 142 degrees with respect to the center C2 of the holder 130, the fastening state between the hook 122 and the holder 130 may be formed unstably. In other words, the fastening stability between the hook 122 and the holder 130 appears low.

[0066] Accordingly, the visor 120 may not be properly formed in a closed state to close the face opening portion 111. In addition, while the visor 120 is in a closed state that closes the face opening portion 111, problems may occur in which the hook 122 is easily separated from the holder 130 by an external force unrelated to the user's intention, thereby causing the visor 120 to open.

[0067] Meanwhile, considering the stability of the fastening between the hook 122 and the holder 130 as well as the usability during separating, it is preferable that the hook 122 surrounds the holder 130 by 262 degrees or less based on the center C2 of the holder 130 while being fastened to the holder 130. When the end of the hook 122 is disposed on a straight line L2 passing through the center point P and forms a 60-degree angle with the tangent line L1 of the holder 130 passing through the center point P, it was confirmed that the hook 122 surrounds the holder 130 by 262 degrees based on the center C2 of the holder 130 while being fastened to the holder 130.

[0068] If the hook 122 is fastened to the holder 130 and surrounds the holder 130 by more than 262 degrees based on the center C2 of the holder 130, problems may occur in which excessive deformation of the hook 122 is required during the process of fastening and separating the hook 122 and the holder 130.

[0069] As a result of the kinematic analysis, the correlation between the angle A formed by the tangent line L1 of the holder 130 passing through the center point P and the straight line passing through the end of the hook 122 and the center point P, and the angle B surrounding the holder 130 based on the center C2 of the holder 130 while the hook 122 is attached to the holder 130 is shown in Table 1 below. [Table 1]A (Unit Degrees)B (Unit Degrees)60262582585525248237-10142

[0070] Referring to Table 1, when the angle A formed by the tangent line L1 of the holder 130 passing through the center point P and the straight line passing through the end of the hook 122 and the center point P is 60 degrees, 58 degrees, 55 degrees, 48 degrees and -10 degrees, the angle B surrounding the holder 130 based on the center C2 of the holder 130 while the hook 122 is fastened to the holder 130 is 262 degrees, 258 degrees, 252 degrees, 237 degrees and 142 degrees, respectively. Considering the above matters, it is preferable that the hook 122 surrounds the holder 130 by 142 degrees or more based on the center C2 of the holder 130 while the hook 122 is fastened to the holder 130. In addition, it is preferable that the hook 122 is disposed to surround the holder 130 at an angle of 262 degrees or less based on the center C2 of the holder 130 while being fastened to the holder 130. As described above, the helmet 100 according to one embodiment of the present invention enables the visor 120 to be stably fixed through the hook 122 and the holder 130, and provides a smooth usage feeling when opening or closing the visor 120.

[0071] Although the embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments presented in the present specification, and those skilled in the art who understand the concept of the present invention will be able to easily propose other embodiments by adding, changing, deleting or supplementing components within the scope of the same concept, but this will also be considered to fall within the concept of the present invention.
