helmet
[0001] The present invention relates to a helmet, and more particularly, to a helmet that protects a wearer's head from external impact.
[0002] Motorcycles, personal mobility devices (PMs), and other two-wheeled vehicles lack adequate means to protect their occupants in the event of an accident. Consequently, the risk of direct impact being transmitted directly to the occupants in the event of an accident is extremely high. Therefore, helmets are mandatory for riders of motorcycles and PMs to protect their heads.
[0003] Typically, a helmet has a shape that envelops the user's head and may include a helmet body with an open portion at the front, and a visor that is attached to the helmet body. The visor is made of a translucent or transparent material and covers the open portion of the helmet body. When positioned, it secures the user's field of vision while protecting the user's eyes and face from wind, foreign objects, etc.
[0004] The visor is pivotally attached to the helmet body, allowing the user to open or close the open portion of the helmet body. The visor must be securely fixed in place when positioned to close the open portion of the helmet body. This is because unintentional opening of the visor while riding a motorcycle or personal mobility device can pose a safety risk. Furthermore, from a usability perspective, the visor must be operable without excessive force.
[0005] Therefore, a helmet is required in which the visor is stably fixed in the closed state, does not open easily, and yet allows the user to operate the visor smoothly and easily when opening or closing it.
[0006] (Patent Document) Korean Patent No. 2558430 "Helmet", registered on July 18, 2023.
[0007] The present invention is intended to solve the above problems, and an object of the present invention is to provide a helmet in which the visor is stably fixed when closed and the visor can be easily operated when the user opens or closes the visor.
[0008] Another object of the present invention is to provide a helmet having a smooth wearing experience by appropriately setting the threshold force required when the hook of the visor is fastened to or detached from the holder.
[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.
[0010] According to one aspect of the present invention, a helmet is provided, comprising: a helmet body having a face opening; a visor pivotally coupled to the helmet body so as to be able to open or close the face opening and having a hook at a lower end; and a rod-shaped holder disposed on the helmet body so as to be able to fasten the hook to an outer surface thereof.
[0011] At this time, the holder has a cylindrical shape, and the hook can be arranged to surround a portion of the outer circumference of the holder so as to have a certain level or more of resistance to a force acting in the opening direction of the visor while the hook is fastened to the holder.
[0012] Additionally, the visor has a visor body formed to open or close the facial opening, and the hook can be formed by recessing the visor body.
[0013] Additionally, the holder may include a core member and a tube that is fitted and arranged on an outer surface of the core member and can rotate with respect to the core member when the hook is fastened to or detached from the holder.
[0014] Additionally, the hook may be arranged to surround the holder by 142 degrees or more based on the center of the holder while being fastened to the holder.
[0015] In addition, when the visor is fastened to the holder, and the point furthest from the pivot axis among the two points where the line passing through the pivot axis of the visor and the center of the holder intersects the holder is taken as the center point, the tangent line of the holder passing through the center point and the straight line passing through the end of the hook and the center point can form an angle of -10 degrees or more and 60 degrees or less.
[0016] Additionally, the helmet body has a slot into which the hook is inserted when the visor is in a position to close the facial opening, and the holder can be arranged to cross the inside of the slot in a transverse direction.
[0017] According to the above configuration, a helmet according to one aspect of the present invention not only enables the visor to be stably fixed through the hook and rod-shaped holder of the visor, but also enables the visor to be easily operated when opening and closing the visor.
[0018] In addition, a helmet according to one aspect of the present invention can provide a smooth user experience and lower the threshold force required when a hook of a visor is fastened to or detached from a holder through a tube that is rotatably arranged with respect to a core member.
[0019] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

[0030] Fig. 1 is a perspective view of a helmet according to one embodiment of the present invention. Furthermore, Fig. 2 is a perspective view of the visor of the helmet according to one embodiment of the present invention in an open state. Meanwhile, Fig. 3 is a side view of the visor of the helmet according to one embodiment of the present invention in an open state.
[0031] 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).
[0032] The helmet body (110) is positioned to surround the user's head. The helmet body (110) forms the 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.
[0033] For example, the helmet body (110) may include an outer shell having high strength formed of a hard synthetic resin or the like, and a shock absorber provided inside the outer shell. At this time, the shock absorber may be formed of expanded polystyrene (EPS), or the like.
[0034] The helmet body (110) has a face opening (111). The face opening (111) is formed at the front of the helmet body (110). The face opening (111) secures a field of vision for a user wearing the helmet (100). The face opening (111) can be closed or opened by a visor (120).
[0035] 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 (111). In one embodiment of the present invention, a pair of slots (112) are provided, one on each of the front side and the other side of the helmet body (110).
[0036] The visor (120) is pivotally connected to the helmet body (110) so that the face opening (111) can be opened or closed. The visor (120) closes the face opening (111) and blocks wind, foreign substances, etc. from the face of a user wearing the helmet (100) when positioned.
[0037] In one embodiment of the present invention, the visor (120) may be coupled to the helmet body (110) at one side and the other side. At this time, the one side and the other side of the visor (120) coupled to the helmet body (110) may function as a pivot axis.
[0038] The visor (120) may include a visor body (121) formed to close or open the facial opening (111), and a hook (122) provided at the bottom of the visor body (121).
[0039] 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.
[0040] A hook (122) may be provided at the bottom of the visor body (121). The hook (122) secures the visor (120) so that the visor (120) can maintain a state in which the facial opening (111) is closed when fastened to a holder (130) described later.
[0041] In one embodiment of the present invention, the hook (122) may be formed by inserting the visor body (121). More specifically, a pair of hooks (122) may be provided, one at each of the lower ends of one side and the other side of the visor body (121).
[0042] The holder (130) is positioned on the helmet body (110) so that a hook (122) can be fastened to the outer surface. In one embodiment of the present invention, the holder (130) may be positioned transversely across the interior of the slot (112). In addition, at least one of one longitudinal end and the other longitudinal end of the holder (130) may be fixed to the wall of the body (110) forming the slot (112).
[0043] The holder (130) is connected 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 connecting the hook (122) to the holder (130) or detaching the hook (122) from the holder (130).
[0044] 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 arranged to surround a portion of the outer circumference 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) when the hook (122) is fastened to the holder (130).
[0045] 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).
[0046] The core member (131) may have a cylindrical shape. In addition, at least one of one longitudinal end and the other longitudinal end of the core member (131) may be fixed to the wall of the main body (110) forming a slot (112).
[0047] The tube (132) is arranged to fit onto the outer surface of the core member (131). In other words, the tube (132) is arranged to surround the outer surface of the core member (131). The tube (132) can rotate with respect to the core member (131) when the hook (122) is fastened to or detached from the holder (130).
[0048] 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.
[0049] Referring to FIG. 5, when the visor (120) pivots in a closing direction to close the facial opening (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).
[0050] At this time, the tube (132) can be rotated in the first direction by the hook (122). Here, the first direction can 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.
[0051] 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) can be lowered by rotating the tube (132) in the first direction. Accordingly, the hook (122) can be smoothly fastened to the holder (130).
[0052] FIG. 6 is a drawing showing the rotation of a tube when a visor of a helmet according to one embodiment of the present invention is separated from a holder.
[0053] Referring to FIG. 6, when the visor (120) pivots in the opening direction to open the facial opening (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).
[0054] At this time, the tube (132) can be rotated in a second direction opposite to the first direction by the hook (122). Here, the second direction can 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.
[0055] 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) can be lowered by rotating the tube (132) in the second direction. Accordingly, the hook (122) can be smoothly separated from the holder (130).
[0056] As described above, the holder (130) is fitted to the outer surface of the core member (131) and can reduce the 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 can provide a smooth user experience during the opening and closing process of the visor (120) through the tube (132).
[0057] 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.
[0058] FIG. 7 is a drawing showing the arrangement of the pivot axis and holder of the visor of the helmet in a closed state according to one embodiment of the present invention.
[0059] Referring to Fig. 7, when the visor (120) is fastened to the holder (130), the point further from the pivot axis (C1) among the two points where a line passing through the pivot axis (C1) of the visor (120) and the center (C2) of the holder (130) intersects the holder (130) can be defined as the center point (P).
[0060] When the center point (P) is defined as above, 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) can form a predetermined angle (A). The predetermined angle (A) can be -10 degrees or more and 60 degrees or less.
[0061] The above angle (A) can be determined by the position of the end of the hook (122). In addition, the yin and yang of the angle can be defined such that when the end of the hook is located 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 located on the rear side of the helmet (100), it appears as positive.
[0062] 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 arranged to form an angle of 60 degrees with a tangent line (L1) of the holder (130) passing through the center point (P).
[0063] 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 arranged at an angle greater than 60 degrees with the tangent line (L1) of the holder (130), the hook (122) must be excessively deformed when attaching or detaching the hook (122) to or from the holder (130), which reduces usability.
[0064] Additionally, the end of the hook (122) may be positioned 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).
[0065] 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 arranged 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.
[0066] Considering the above points, it is preferable that the end of the hook (122) be positioned 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).
[0067] When the end of the hook (122) is positioned within this range, the stability of the fastening between the hook (122) and the holder (130), usability during the fastening or detachment process of the hook (122) and the holder (130), etc. can be appropriately secured.
[0068] Meanwhile, the relationship between the hook (122) and the holder (130) can also be explained from the following perspective.
[0069] The hook (122) can be arranged to surround the holder (130) by 142 degrees or more based on the center (C2) of the holder (130) when it is fastened to the holder (130). When the end (P2) of the hook (122) is arranged 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).
[0070] Here, the angle (B) at which the hook (122) surrounds the holder (130) can be defined as the angle formed by the point (P1) where 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).
[0071] If the hook (122) is positioned so that it contacts 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 unstable. In other words, the fastening stability between the hook (122) and the holder (130) appears low.
[0072] Accordingly, the visor (120) may not be properly formed in a closed state to close the face opening (111). In addition, when the visor (120) is in a closed state to close the face opening (111), a problem may occur in which the hook (122) is easily separated from the holder (130) by an external force unrelated to the user's intention, causing the visor (120) to open.
[0073] Meanwhile, considering the stability of the fastening between the hook (122) and the holder (130) as well as the usability when separated, it is preferable that the hook (122) surround the holder (130) by 262 degrees or less based on the center (C2) of the holder (130) when fastened to the holder (130). When the end of the hook (122) is arranged on a straight line (L2) passing through the center point (P) and forms an angle of 60 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 262 degrees based on the center (C2) of the holder (130) when fastened to the holder (130).
[0074] If the hook (122) surrounds the holder (130) by more than 262 degrees based on the center (C2) of the holder (130) while it is fastened to the holder (130), a problem may occur in which excessive deformation of the hook (122) is required during the process of fastening and detaching the hook (122) and the holder (130).
[0075] 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) when the hook (122) is fastened to the holder (130) is shown in Table 1 below.
[0076] A(unit degree)B(unit degree)60262582585525248237-10142
[0077] 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) when 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, it is preferable that the hook (122) surround the holder (130) by 142 degrees or more based on the center (C2) of the holder (130) when the hook (122) is fastened to the holder (130). In addition, it is preferable that the hook (122) be arranged 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 user experience when opening or closing the visor (120).
[0078] Although 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 will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit. However, this will also be considered to fall within the spirit of the present invention.
