Description

helmet

[0001] The present invention relates to a helmet, and more particularly, to a helmet configured to prevent a wire used for moving a sub-visor relative to a helmet body from being damaged by excessive bending.

[0002] Motorcycles lack adequate means to protect occupants in the event of an accident, and the risk of the impact being directly transmitted to the occupants is extremely high. Therefore, motorcycle riders are required to wear helmets to protect their heads.

[0003] Typically, a helmet includes a helmet body that protects the user's head from external impact, and a visor that is attached to the helmet body to cover the facial opening of the helmet body.

[0004] The visor protects the rider's eyes by preventing outside air from entering the helmet during riding. Made of transparent or translucent material, the visor ensures the rider's field of vision.

[0005] Recently, helmets equipped with a visor (hereinafter referred to as the main visor) to block the inflow of outside air and a sub-visor to block sunlight, etc., are being used separately from the main visor.

[0006] Previously, a technology was developed to manipulate the position and movement of the visor relative to the helmet body using wires.

[0007] However, the process of operating the visor has resulted in the wires being excessively bent and damaged. This damage shortens the helmet's lifespan and increases the time and cost of helmet maintenance.

[0008] The present invention is intended to solve the above problems, and an object of the present invention is to provide a helmet configured so that the wire is not excessively bent and damaged during the subvisor operation process.

[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 formed on a front side; a sub-visor movably coupled to the helmet body and capable of partially covering the face opening of the helmet body; a movable member movably coupled to the helmet body and coupled to the sub-visor and capable of moving together with the sub-visor; an adjusting member movably coupled to the helmet body while being spaced apart from the movable member; and a wire having both ends coupled to the movable member and the adjusting member and moving together, wherein at least one of the movable member and the adjusting member is formed to prevent the wire from being bent and damaged by a compressive force acting on the wire when moving in a direction in which the wire is pushed.

[0011] At this time, the movable member may include a movable member body part to which one end of the wire is coupled and which is movably coupled to the helmet body; and a first damage prevention part that extends from the movable member body part and supports a part of the wire that is bent by a compressive force applied to the wire when the movable member body part pushes the wire.

[0013] At this time, a first sheath fixing portion may be formed on the other side of the first support member to which one end of a sheath that wraps the wire is fixed.

[0014] Meanwhile, the first damage prevention portion may be formed to support a curved portion of the wire generated by a compressive force applied to the wire when the movable member body portion pushes the wire.

[0015] At this time, the first damage prevention part may include a first support wall extending from the body of the moving member and supporting the curved part of the wire; and at least one first connecting wall connected to the first support wall.

[0016] Meanwhile, a first guide groove may be formed in the first support member to guide movement of the movable member, and a first guide protrusion that moves along the first guide groove may be formed in the movable member.

[0017] Meanwhile, the wire has a wire body; and a spherical shape, and includes a first end formed at one end of the wire body, and a first insertion groove into which the first end is inserted may be formed in the moving member body.

[0018] At this time, at least one first catch may be formed on the inner wall defining the first insertion groove to prevent the first end portion from coming out of the first insertion groove.

[0019] At this time, the inner diameter of the first insertion groove may be larger than the outer diameter of the first end portion.

[0020] Meanwhile, a first through hole may be formed in the inner wall defining the first insertion groove, which communicates with the first insertion groove and through which a portion of the wire body is positioned to pass.

[0021] Meanwhile, the helmet may further include a position adjustment member that is rotatably coupled to one side of the first support member at a predetermined angle, and whose portion in contact with the movable member changes depending on the rotation angle.

[0022] Meanwhile, the adjusting member may include an adjusting member body part to which the other end of the wire is coupled and which is movably coupled to the helmet body; and a second damage prevention part that extends from the adjusting member body part and supports a part of the wire that is bent by a compressive force applied to the wire when the adjusting member body part pushes the wire.

[0023] At this time, the helmet further includes a second support member that is coupled to the helmet body and to which the adjustment member is movably coupled, and the adjustment member is movable from one side to the other side of the second support member (600).

[0024] A second sheath fixing portion may be formed on the other side of the second support member to which one end of a sheath that wraps the wire is fixed.

[0025] Meanwhile, the second damage prevention portion may be extended so that the curved portion of the wire generated by the compressive force applied to the wire when the body of the adjusting member pushes the wire is in contact with and supported.

[0026] At this time, the second damage prevention part may include a second support wall extending from the body of the adjusting member and supporting the curved portion of the wire; and at least one second connecting wall connected to the second support wall.

[0027] Meanwhile, a second guide groove may be formed in the second support member to guide movement of the adjustment member.

[0028] Meanwhile, the second support member comprises: a first support body disposed on the inside of the helmet body; and

[0029] It may include a second support body arranged on the outside of the helmet body and coupled to the first support body.

[0030] Meanwhile, the wire has a wire body; and a spherical shape, and includes a second terminal formed at the other end of the wire body, and a second insertion groove into which the second terminal is inserted may be formed in the adjusting member body.

[0050] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts irrelevant to the description are omitted in the drawings, and the same reference numerals designate identical or similar components throughout the specification.

[0051] The words and terms used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, but should be interpreted in a way that is consistent with the technical idea of ​​the present invention, in accordance with the principles by which the inventor can define terms and concepts in order to best explain his or her invention.

[0052] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings correspond to a preferred embodiment of the present invention, and do not represent all of the technical ideas of the present invention, so there may be various equivalents and modified examples that can replace the configuration at the time of filing of the present invention.

[0053] In this specification, terms such as “include” or “have” are intended to describe the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0054] When a component is said to be "in front of," "behind," "above," or "below" another component, this includes not only being placed "in front of," "behind," "above," or "below" the other component in direct contact with it, but also if there is another component intervening therebetween. Furthermore, when a component is said to be "connected" to another component, this includes not only being directly connected to one another, but also being indirectly connected to one another, unless there are special circumstances.

[0055] FIG. 1 is a perspective view showing a helmet according to one embodiment of the present invention, FIG. 2 is an exploded perspective view of a helmet according to one embodiment of the present invention, and FIG. 3 is a side view of a part of a helmet according to one embodiment of the present invention.

[0056] Referring to FIGS. 1 to 3, a helmet (10) according to the present embodiment includes a helmet body (100), a main visor (210), a sub-visor (230), a moving member (300), an adjusting member (500), and a wire (700).

[0057] In one embodiment of the present invention, both ends of the wire (700) are respectively coupled to the movable member (300) and the adjusting member (500), and the movable member (300), the adjusting member (500), and the wire (700) can move together. In other words, the wire (700) is respectively coupled to the movable member (300) and the adjusting member (500) to link the movable member (300) and the adjusting member (500).

[0058] A user can move a movable member (300) connected to the movable member (500) by a wire (700) by performing an operation to move the movable member (500). In this case, the subvisor (230) coupled to the movable member (300) can move relative to the helmet body (100).

[0059] For example, a user can move the adjustment member (500) from a position indicated by a solid line in FIG. 3 to a position indicated by a dotted line. At this time, the adjustment member (500) can move in the direction of the solid arrow as seen in FIG. 3.

[0060] At this time, the wire (700) coupled with the adjusting member (500) pulls and moves the movable member (300). In this case, the sub-visor (230) coupled with the movable member (300) can move together with the movable member (300). At this time, the movable member (300) can move in the direction of the solid arrow as seen in FIG. 3.

[0061] For example, a user can move the adjustment member (500) from a position indicated by a dotted line in FIG. 3 to a position indicated by a solid line. At this time, the adjustment member (500) can move in the direction of the dotted arrow as seen in FIG. 3.

[0062] At this time, the wire (700) coupled with the adjusting member (500) pushes and moves the movable member (300). In this case, the subvisor (230) coupled with the movable member (300) can move together with the movable member (300). At this time, the subvisor (230) can move in the direction of the dotted arrow as seen in Fig. 3.

[0063] In one embodiment of the present invention, when an external force is applied to the adjusting member (500) or the moving member (300) in a direction that pushes the wire (700), a compressive force is applied to the wire (700), and the wire (700) may be bent. At this time, if the wire (700) is bent excessively, damage to the wire (700) may occur.

[0064] FIG. 4 is a drawing showing an example in which a compressive force is generated in a wire that links an adjusting member and a moving member according to one embodiment of the present invention, and FIG. 5 is a drawing showing another example in which a compressive force is generated in a wire that moves an adjusting member and a moving member according to one embodiment of the present invention.

[0065] Referring to FIG. 4, the subvisor (230) can be placed at a first visor limit position as shown in FIG. 4 with respect to the helmet body (100). Here, the first visor limit position of the subvisor (230) means a position at which the subvisor (230) can be lowered to the maximum with respect to the helmet body (100).

[0066] In FIG. 4, when the subvisor (230) is at the first visor limit position, the movable member (300) is at the first movable member limit position, and the adjusting member (500) is at the first adjusting member limit position. That is, the first visor limit position, the first movable member limit position, and the first adjusting member limit position correspond to each other.

[0067] A user can apply a force (F) to the subvisor (230) to move the subvisor (230) to the upper right as seen in FIG. 4. At this time, the moving member (300) coupled with the subvisor (230) also moves.

[0068] In this case, the moving member (300) pushes the wire (700) toward the adjusting member (500), and accordingly, the adjusting member (500) moves downward to the left as seen in Fig. 4. In this process, a compressive force is applied to the wire (700).

[0069] Referring to FIG. 5, the subvisor (230) can be placed at a second visor limit position as shown in FIG. 5 with respect to the helmet body (100). Here, the second visor limit position of the subvisor (230) means a position at which the subvisor (230) can be raised to the maximum with respect to the helmet body (100).

[0070] In FIG. 5, when the sub-visor (230) is at the second visor limit position, the movable member (300) is at the second movable member limit position, and the adjusting member (500) is at the second adjusting member limit position. That is, the second visor limit position, the second movable member limit position, and the second adjusting member limit position correspond to each other.

[0071] A user can apply a force (F) to the adjusting member (500) to move the adjusting member (500) to the upper right as seen in FIG. 5. In this case, the adjusting member (500) pushes the wire (700) toward the moving member (300), and thus the moving member (300) can move to the lower left as seen in FIG. 5. In this process, a compressive force is applied to the wire (700).

[0072] In this case, the sub-visor (230) coupled to the movable member (300) also moves together with the movable member (300).

[0073] When a compressive force is applied to the wire (700) as shown in FIGS. 4 and 5, the wire (700) may bend. If the wire (700) is bent excessively, the wire (700) may be damaged and lose its function.

[0074] In one embodiment of the present invention, to solve the above problem, at least one of the movable member (300) and the adjusting member (500) is provided with a means for preventing the wire (700) from being excessively bent and damaged by compressive force. This means for preventing damage to the wire (700) will be described later.

[0075] Hereinafter, a helmet (10) according to one embodiment of the present invention will be specifically described with reference to FIGS. 1 to 5.

[0076] The helmet body (100) may have a structure that wraps around the user's head to protect the user's head. The helmet body (100) is worn on the user's head and protects the user's head from external impact. The helmet body (100) may be provided with a face opening (100a) at the front to secure the user's field of vision.

[0077] The helmet body (100) may be formed of a material capable of absorbing shock. For example, the helmet body (100) may include an outer shell having high strength, formed of a hard synthetic resin, 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.

[0078] The facial opening (100a) of the helmet body (100) can be closed or opened by the main visor (210).

[0079] The main visor (210) protects the user's eyes by blocking external air directed toward the face of the user wearing the helmet (10). The main visor (210) is made of a transparent or translucent material to ensure the user's field of vision.

[0080] The main visor (210) can be movably coupled to the helmet body (100) to open and close the face opening (100a) of the helmet body (100). At this time, the main visor (210) can be pivotally coupled to the helmet body (100). Alternatively, the main visor (210) can be movably coupled to the helmet body (100) along a curved trajectory.

[0081] In one embodiment of the present invention, the main visor (210) is not operated by wires, and only the sub-visor (230) is operated by wires (700). However, in other embodiments, the main visor may be operated by wires. In this case, it goes without saying that the wire damage prevention measures described below may be equally applied to the wires used to operate the main visor.

[0082] In one embodiment of the present invention, the subvisor (230) may be positioned at the rear of the main visor (210). The subvisor (230) blocks light, etc., from entering the user's face through the face opening (100a) of the helmet body (100).

[0083] The subvisor (230) can partially cover the facial opening (100a) of the helmet body (100). In one embodiment of the present invention, a wire (700) is used to adjust the position of the subvisor (230) with respect to the helmet body (100) and to manipulate its movement with respect to the helmet body (100).

[0084] The subvisor (230) can be movably coupled to the helmet body (100). At this time, the subvisor (230) can be movably coupled to the helmet body (100).

[0085] When the subvisor (230) moves downward, the area of ​​the subvisor (230) covering the facial opening (100a) of the helmet body (100) increases. And when the subvisor (230) moves upward, the area of ​​the subvisor (230) covering the facial opening (100a) of the helmet body (100) decreases.

[0086] In one embodiment of the present invention, the subvisor (230) is coupled to a movable member (300) that is movably coupled to the helmet body (100). At this time, the subvisor (230) can move with respect to the helmet body (100) together with the movable member (300). In this case, the subvisor (230) can be movably coupled to the helmet body (100) via the movable member (300).

[0087] The movable member (300) can be movably coupled to one side of the helmet body (100). For example, the movable member (300) can be movably coupled to the right side of the helmet body (100) as seen in FIG. 2.

[0088] At this time, the movable member (300) can be movably coupled to the first support member (400) that is fixedly coupled to one side of the helmet body (100). In this case, the movable member (300) is movably coupled to the helmet body (100) via the first support member (400).

[0089] The movable member (300) can move between one side and the other side of the first support member (400). For example, the movable member (300) can move between the lower left side and the upper right side of the first support member (400) as seen in FIG. 3. In other words, the movable member (300) can move between the first movable member limit position as shown in FIG. 4 and the second movable member limit position as shown in FIG. 5 with respect to the first support member (400).

[0090] The assembly (hereinafter referred to as the main assembly) in which the movable member (300) and the first support member (400) are combined can be integrally modularized and attached to the inside of the helmet body (100). At this time, the main assembly is attached to the right inner side of the helmet body (100) as seen in FIG. 2, and as seen in FIG. 2, it supports the right side of the sub-visor (230) so as to be movable with respect to the helmet body (100).

[0091] For reference, in Fig. 2, a sub-assembly having a structure identical or similar to that of the main assembly in which the movable member (300) and the first support member (400) are combined is omitted. Here, the sub-assembly is an assembly in which a sub-movable member (not shown) having a structure identical or similar to that of the movable member (300) and a first sub-support member (not shown) having a structure identical or similar to that of the first support member (400) are combined.

[0092] This sub-assembly is attached to the left inner side of the helmet body (100) as seen in FIG. 2, and can movably support the left side of the sub-visor (230) with respect to the helmet body (100) as seen in FIG. 2.

[0093] Fig. 6 is a drawing showing a state before the movable member and the first support member are mutually coupled, viewed from one direction, and Fig. 7 is a drawing showing a state before the movable member and the first support member are mutually coupled, viewed from another direction. For reference, in Figs. 6 and 7, coupling means such as bolts for coupling the movable member and the first support member are omitted.

[0094] Referring to FIGS. 1 to 7, the movable member (300) is connected to one end of the wire (700). At this time, the wire (700) can move together with the movable member (300) when the movable member (300) moves relative to the helmet body (100).

[0095] The movable member (300) may be configured to include a movable member body (310) and a first damage prevention member (330).

[0096] A sub-visor (230) is coupled to the movable member body (310). For example, a clamp-shaped coupling portion (231) may be formed on the sub-visor (230), and a pillar-shaped coupling portion (315) may be formed on the movable member body (310) to be coupled to the clamp-shaped coupling portion (231) of the sub-visor (230).

[0097] A space (316) for accommodating a clamp-shaped coupling part (231) around a column-shaped coupling part (315) may be provided in the movable member body (310), and an entrance (317) may be formed for the clamp-shaped coupling part (231) to approach the column-shaped coupling part (315).

[0098] One end of a wire (700) is connected to the movable member body (310). At this time, a first insertion groove (313) is formed in the movable member body (310) into which a first end (730) formed at one end of the wire body (710) is inserted. The first insertion groove (313) will be described later.

[0099] The movable member body (310) is movably coupled to the first support member (400). At this time, the movable member body (310) is movably coupled to the helmet body (100) via the first support member (400).

[0100] In one embodiment of the present invention, a first guide protrusion (311) may be formed on one surface of the movable member body (310) facing the first support member (400), and a first guide groove (430) may be formed on one surface of the first support member (400) facing the movable member body (310) by inserting the first guide protrusion (311) therein so as to be movable. The first guide groove (430) is formed to extend along the movement direction of the movable member (300).

[0101] For example, the first guide groove (430) can be formed by penetrating the first support member (400) as shown in FIGS. 6 and 7. The first guide groove (430) is formed by penetrating one surface and the other surface of the first support member (400).

[0102] At this time, the first guide protrusion (311) can be positioned to penetrate the first guide groove (430).

[0103] At this time, a washer (not shown) may be coupled to the penetration end of the first guide protrusion (311) by a bolt (not shown). The washer is formed so as to be caught on the periphery of the first guide groove (430) on the other surface of the first support member (400) when the first guide protrusion (311) attempts to detach from the first guide groove (430). As a result, detachment of the first guide protrusion (311) from the first guide groove (430) can be prevented. These washers and bolts also function as a coupling means between the movable member and the first support member.

[0104] Alternatively, it goes without saying that various separation prevention means other than washers and bolts can be used to prevent the first guide projection (311) from being separated from the first guide groove (430).

[0105] The first damage prevention part (330) extends from the movable member body part (310). The first damage prevention part (330) prevents the wire (700) that is pressed by the movable member body part (310) from being excessively bent and damaged.

[0106] The first damage prevention part (330) is formed to extend from the movable member body part (310) in the direction in which the movable member body part (310) pushes the wire (700).

[0107] The first damage prevention portion (330) supports a portion of the wire (700) that is bent by the compressive force when the movable member body (310) pushes the wire (700). In other words, the first damage prevention portion (330) supports a portion of the wire (700) that is bent by the compressive force when the wire (700) pushes the movable member body (310).

[0108] FIG. 8 and FIG. 9 are drawings for explaining a mechanism by which a first damage prevention part of a movable member according to one embodiment of the present invention prevents damage to a wire, and FIG. 10 is an enlarged perspective view of the periphery of the first damage prevention part of a movable member according to one embodiment of the present invention.

[0109] For reference, in FIGS. 8 and 9, the sub-visor (230) coupled to the movable member (300) is omitted, and the movable member (300) is indicated with a dotted line to increase the visibility of the wire (700) covered by the movable member (300).

[0110] Referring to FIG. 8, the movable member (300) is positioned on one side of the first support member (400). At this time, it can be said that the movable member (300) is positioned at the first movable member limit position with respect to the first support member (400).

[0111] When the movable member (300) is stopped on one side of the support member (400) as shown in FIG. 8, and the user applies force to the sub-visor (not shown) as shown in FIG. 9 to move the movable member (300) coupled with the sub-visor to the other side of the first support member (400), a compressive force is applied to the wire (700) pushed by the movable member (300) so that it may bend.

[0112] At this time, the first damage prevention part (330) of the movable member (300) can prevent damage to the wire (700) due to excessive bending by supporting a part of the bent wire (700).

[0113] At this time, the first damage prevention part (330) can be formed to support the curved part (K1) of the wire (700) generated by the compressive force acting on the wire (700) as shown in FIGS. 9 and 10.

[0114] Referring to FIGS. 6 to 10, the first damage prevention unit (330) may include a first support wall (331) that supports the curved portion (K1) of the wire (700). The first support wall (331) of the first damage prevention unit (330) is positioned in a direction in which the wire (700) is expected to bend due to a compressive force.

[0115] For example, the movable member body (310) can move along the first guide groove (430) formed in the first support member (400) with a predetermined curvature and push the wire (700). At this time, the movable member body (310) moves along a curved trajectory with a predetermined curvature and pushes the wire (700).

[0116] In this case, the wire (700) on which the compressive force is applied is convexly bent in the same direction as the convex direction of the moving trajectory curve of the moving member body (310). At this time, the first support wall (331) of the first damage prevention part (330) is arranged in the direction in which the wire (700) is bent to support the curved portion (K1) of the wire (700).

[0117] The first support wall (331) of the first damage prevention section (330) can be formed to be extended to a sufficient extent to cover and support the bending portion (K1) of the wire (700) caused by the compressive force.

[0118] The first damage prevention member (330) may further include at least one first connecting wall (333) connected to the first support wall (331). The first connecting wall (333) may form a tunnel structure that surrounds a portion of the wire (700) in the extension direction together with the first support wall (331).

[0119] The first connecting wall (333) may have a partially open structure as illustrated in Fig. 6. Alternatively, the first connecting wall (333) may have a completely closed structure, although this is not illustrated.

[0120] The first connecting wall (333) can serve to support the curved portion of the wire (700) when the wire (700) is bent in an unexpected direction.

[0121] The first damage prevention unit (330) may be manufactured integrally with the movable member body (310). Alternatively, the first damage prevention unit (330) may be manufactured separately from the movable member body (310) and then integrally joined to the movable member body (310).

[0122] Referring to FIGS. 2 to 9, the first support member (400) movably supports the movable member (300). At this time, the movable member (300) can be movably supported on the helmet body (100) via the first support member (400).

[0123] The first support member (400) may be bolted or rivet-attached to the helmet body (100). Alternatively, the first support member (400) may be attached to the helmet body (100) using various known methods.

[0124] The first support member (400) may be formed to extend in the direction of movement of the subvisor (230) with respect to the helmet body (100), but is not limited thereto.

[0125] A first guide groove (430) is formed on one surface of the first support member (400) to guide the movement of the movable member (300), and a first guide protrusion (311) inserted into the first guide groove (430) is formed on one surface of the movable member (300).

[0126] In one embodiment of the present invention, the first guide home (430) may be formed to extend into a curved shape having a predetermined curvature.

[0127] At this time, the first guide groove (430) may be formed to extend into a curved shape having a single curvature as shown in Fig. 7. Alternatively, although not shown, the first guide groove may be formed to extend into a curved shape having two or more curvatures.

[0128] As another example, although not shown, the first guide home may be formed in a straight line shape or in a shape combining straight lines and curves.

[0129] In one embodiment of the present invention, a first auxiliary guide protrusion (318) may be formed protrudingly on a side surface of the movable member (300). In other words, the first auxiliary guide protrusion (318) may be formed on a side surface in the width direction of the movable member (300). For reference, the movable member (300) extends in the movement direction.

[0130] At this time, the first auxiliary guide protrusion (318) may be formed to protrude from at least one side of the movable member body (310) and the first damage prevention portion (330). For example, the first auxiliary guide protrusion (318) may be formed to span the movable member body (310) and the first damage prevention portion (330). At this time, the first auxiliary guide protrusion (318) may be formed to extend continuously or discontinuously.

[0131] At this time, a first auxiliary guide (440) can be formed on one surface of the first support member (400) to correspond to the first auxiliary guide protrusion (318).

[0132] The first auxiliary guide (440) may have a structure that protrudes from one surface of the first support member (400) and surrounds the first auxiliary guide protrusion (318). The first auxiliary guide (440) extends in the movement direction of the moving member (300) to provide a first auxiliary guide groove (440a) that guides the movement of the first auxiliary guide protrusion (318).

[0133] A first sheath fixing portion (410) may be formed on the other side of the first support member (400), to which one end of a sheath (800) wrapping a wire (700) is fixed. The sheath (800) is formed in a hollow shape, and the wire (700) can slide and move within the sheath (800).

[0134] The first sheath fixing part (410) has a socket shape, and one end of the sheath (800) can be fixedly connected by being fitted into the first sheath fixing part (410).

[0135] A wire (700) is exposed to the outside from one end of the sheath (800) fixed to the first sheath fixing member (410). One end of the wire (700) exposed from one end of the sheath (800) is coupled to the moving member (300).

[0136] When the movable member (300) moves from one side to the other side of the first support member (400), the first sheath fixing member (410) located on the other side of the first support member (400) can be covered by the first damage prevention member (330) as shown in Fig. 5. At this time, the first sheath fixing member (410) is located inside the tunnel structure provided by the first damage prevention member (330).

[0137] Figures 11 and 12 are enlarged views of a position adjustment member according to one embodiment of the present invention. Referring to Figures 6, 7, 11, and 12, a helmet (10) according to one embodiment of the present invention may further include a position adjustment member (460) that adjusts the first movable member limit position of the movable member (300) with respect to the first support member (400).

[0138] Here, the first movable member limit position of the movable member (300) with respect to the first support member (400) is a position corresponding to the first visor limit position of the sub-visor (230). That is, when the movable member (30) is at the first movable member limit position, the sub-visor (230) is positioned at the first visor limit position, i.e., a position where the sub-visor (230) can be lowered to the maximum with respect to the helmet body (100).

[0139] The position adjustment member (460) is rotatably coupled to one side of the first support member (400) at a predetermined angle. At this time, the position adjustment member (460) can be rotatably coupled to a rotational axis (470) formed on one surface of the first support member (400). The position adjustment member (460) can be placed on the opposite side from the side where the first sheath fixing member (410) is located.

[0140] The position adjustment member (460) may have a non-circular plate shape. When the non-circular position adjustment member (460) rotates, the portion that comes into contact with the moving member (300) changes depending on the rotation angle.

[0141] For example, when the rotation angle of the position adjustment member (460) is 0 degrees as in FIG. 11, the first contact portion (460a) of the position adjustment member (460) comes into contact with a specific portion of the moving member (300).

[0142] For example, when the rotation angle of the position adjustment member (460) is approximately 60 degrees as shown in FIG. 12, the second contact portion (460b) of the position adjustment member (460) comes into contact with another specific portion of the moving member (300).

[0143] As can be seen in FIGS. 11 and 12, the first movable member limit position of the movable member (300) with respect to the first support member (400) may vary depending on the rotation angle of the position adjustment member (460). In this case, the first visor limit position of the sub-visor (230) coupled with the movable member (300) may also vary.

[0144] Referring to FIGS. 2 to 5, the adjusting member (500) may be movably coupled to the helmet body (100) while being spaced apart from the movable member (300). For example, the adjusting member (500) may be movably coupled to the right side of the helmet body (100) as seen in FIG. 2 while being spaced apart from the movable member (300).

[0145] At this time, the adjusting member (500) can be movably coupled to the second support member (600) that is fixedly coupled to one side of the helmet body (100). In this case, the movable member (300) is movably coupled to the helmet body (100) via the second support member (600).

[0146] The adjusting member (500) can move between one side and the other side of the second support member (600). For example, the adjusting member (500) can move between the lower left side and the upper right side of the second support member (600) as seen in FIG. 3. In other words, the moving member (300) can move between the first adjusting member limit position as shown in FIG. 4 and the second adjusting member limit position as shown in FIG. 5 with respect to the first support member (400).

[0147] The adjusting member (500) is connected to the movable member (300) by a wire (700) and operates in conjunction with the movable member (300). When a user moves the adjusting member (500), the movable member (300) also moves by the wire (700). At this time, the sub-visor (230) coupled to the movable member (300) also moves.

[0148] Fig. 13 is a drawing showing a state before the adjusting member and the second supporting member are mutually coupled, viewed from one direction, and Fig. 14 is a drawing showing a state before the adjusting member and the second supporting member are mutually coupled, viewed from another direction. However, in Figs. 13 and 14, the adjusting member (500) is shown as being coupled to a portion of the second supporting member (600).

[0149] Referring to FIGS. 2 to 5, 13 and 14, the adjusting member (500) is coupled to the other end of the wire (700). At this time, the wire (700) can move together with the adjusting member (500) when the adjusting member (500) moves relative to the helmet body (100).

[0150] The adjusting member (500) may be configured to include an adjusting member body (510) and a second damage prevention member (530).

[0151] The other end of the wire (700) is coupled to the adjusting member body (510). The adjusting member body (510) can be movably coupled to the second support member (600). At this time, the adjusting member body (510) can be movably coupled to the helmet body (100) via the second support member (600).

[0152] A second insertion groove (513) is formed in the adjusting member body (510) into which a second end portion (740) formed at the other end of the wire body (710) is inserted. The second insertion groove (513) will be described later.

[0153] The adjusting member body (510) may include an inner body (510a) arranged between the first support body (601) and the second support body (602) of the second support member (600) described later, and an outer body (510b) connected to the inner body (510a) and exposed to the outside of the second support member (600).

[0154] The other end of the wire (700) is connected to the inner body (510a). The outer body (510b) is the part that the user holds to move the adjustment member (500).

[0155] The adjusting member body (510) including the inner body (510a) and the outer body (510b) can move along the second guide groove (630) formed in the second support member (600).

[0156] In one embodiment of the present invention, the outer body (510b) exposed to the outside through the second guide home (630) may have a cross-section in the shape of the English letter 'L'.

[0157] At this time, one end of the outer body (510b) is connected to the inner body (510a), and the other end of the outer body (510b) can be inserted into the outer auxiliary guide groove (641) formed on the outer surface of the second support member (600). The outer auxiliary guide groove (641) extends in the same direction as the extension direction of the second guide groove (630).

[0158] The second damage prevention part (530) extends from the adjusting member body part (510). The second damage prevention part (530) prevents the wire (700) that is pressed by the adjusting member body part (510) and subjected to a compressive force from being excessively bent and damaged.

[0159] The second damage prevention part (530) is formed to extend from the adjusting member body part (510) in the direction in which the adjusting member body part (510) pushes the wire (700).

[0160] The second damage prevention portion (530) supports a portion of the wire (700) that is bent by the compressive force when the adjusting member body (510) pushes the wire (700). In other words, the second damage prevention portion (530) supports a portion of the wire (700) that is bent by the compressive force when the wire (700) pushes the adjusting member body (510).

[0161] FIGS. 15 and 16 are drawings for explaining a mechanism by which a second damage prevention part of an adjustment member according to one embodiment of the present invention prevents damage to a wire. For reference, in FIGS. 15 and 16, the second support body (602) of the second support member (600) is omitted, and the adjustment member (500) is indicated with a dotted line to increase the visibility of the wire (700) covered by the adjustment member (500).

[0162] Referring to Fig. 15, the adjusting member (500) is positioned on the other side of the second support member (600). At this time, when the user applies force to the adjusting member (500) as shown in Fig. 16 to move the adjusting member (500) to one side of the second support member (600), a compressive force is applied to the wire (700) pushed by the adjusting member (500), causing it to bend.

[0163] At this time, the second damage prevention part (530) of the adjusting member (500) can prevent damage to the wire (700) due to excessive bending by supporting a part of the bent wire (700).

[0164] At this time, the second damage prevention part (530) can be formed to support the curved part (K2) of the wire (700) generated by the compressive force acting on the wire (700) as shown in FIGS. 15 and 16.

[0165] Referring to FIGS. 13 to 16, the second damage prevention unit (530) may include a second support wall (531) that supports the curved portion (K2) of the wire (700). The second support wall (531) of the second damage prevention unit (530) is positioned in a direction in which the wire (700) is expected to bend due to a compressive force.

[0166] The second support wall (531) of the second damage prevention section (530) can be formed to be extended to a sufficient extent to cover and support the bending portion (K2) of the wire (700) caused by the compressive force.

[0167] The second damage prevention member (530) may further include at least one second connecting wall (533) connected to the second support wall (531). The second connecting wall (533) may form a tunnel structure that partially surrounds a portion of the wire (700) in the extension direction together with the second support wall (531).

[0168] The second connecting wall (533) may have a completely closed structure as illustrated in FIG. 14. Alternatively, the second connecting wall (533) may have a partially open structure, although not illustrated.

[0169] The second connecting wall (533) can serve to support the curved portion of the wire (700) when the wire (700) is bent in an unexpected direction.

[0170] The second damage prevention member (530) having a tunnel structure can move along the inner auxiliary guide groove (643) formed on the inner side of the second support member (600).

[0171] The second damage prevention part (530) may be manufactured integrally with the adjusting member body part (510). Alternatively, the second damage prevention part (530) may be manufactured separately from the adjusting member body part (510) and then integrally joined to the adjusting member body part (510).

[0172] Referring to FIGS. 3 to 5 and 13 to 16, the second support member (600) movably supports the adjustment member (500). At this time, the adjustment member (500) can be movably supported on the helmet body (100) via the second support member (600).

[0173] The second support member (600) may be bolted or rivet-attached to the helmet body (100). Alternatively, the second support member (600) may be attached to the helmet body (100) using various known methods.

[0174] The second support member (600) may be formed to extend in the direction of movement of the adjustment member (500) with respect to the helmet body (100). The adjustment member (500) may be moved between one side and the other side of the second support member (600).

[0175] A second sheath fixing portion (610) may be formed on one side of the second support member (600) to which the other end of the sheath (800) wrapping the wire (700) is fixed.

[0176] The second sheath fixing part (610) has a socket shape, and the other end of the sheath (800) can be fixedly connected by being fitted into the second sheath fixing part (610).

[0177] A wire (700) is exposed to the outside from the other end of the sheath (800) fixed to the second sheath fixing part (610). The other end of the wire (700) exposed from the other end of the sheath (800) is coupled to the adjusting member body (510). At this time, the other end of the wire (700) is coupled to the inner body (510a) of the adjusting member body (510).

[0178] A second guide groove (630) may be formed on one surface of the second support member (600) to guide movement of the adjustment member (500) with respect to the second support member (600). According to one embodiment of the present invention, the second guide groove (630) may be formed at a joint portion of the first support body (601) and the second support body (602) of the second support member (600).

[0179] More specifically, in one embodiment of the present invention, the second support member (600) includes a first support body (601) and a second support body (602). The first support body (601) is disposed on the inside of the helmet body (100), and the second support body (602) is disposed on the outside of the helmet body (100) and can be coupled with the first support body (601).

[0180] At this time, the first support body (601) and the second support body (602) can be mutually coupled with the outer shell of the helmet body (100) interposed therebetween. At this time, the first support body (601) and the second support body (602) can be mutually coupled with a bolt (not shown) penetrating the outer shell of the helmet body (100).

[0181] In one embodiment of the present invention, the adjusting member body (510) may include an inner body (510a) positioned between the first support body (601) and the second support body (602), and an outer body (510b) connected to the inner body (510a) and exposed to the outside.

[0182] Referring to FIGS. 6, 7, 13, and 14, the wire (700) includes a wire body (710), a first end portion (730) formed at one end of the wire body (710), and a second end portion (740) formed at the other end of the wire body (710). The first end portion (730) and the second end portion (740) have a spherical shape.

[0183] FIG. 17 is an enlarged view of a first insertion groove into which a first end portion is inserted according to one embodiment of the present invention, and FIG. 18 is an enlarged view of a second insertion groove into which a second end portion is inserted according to one embodiment of the present invention.

[0184] Referring to FIGS. 6, 7 and 17, a first insertion groove (313) into which a first end portion (730) is inserted is formed in the movable member body portion (310).

[0185] The first insertion groove (313) can be formed in a first protrusion (312) that has a predetermined width and protrudes from one surface of the movable member body (310).

[0186] At least one first catch (313a) may be formed extending toward the center of the first insertion groove (313) on the inner wall defining the first insertion groove (313) to prevent the first end (730) from coming out of the first insertion groove (313).

[0187] In the process of inserting the first end portion (730) into the first insertion groove (313), the first end portion (730) or the first catch (313a) is elastically deformed, making it easier to insert the first end portion (730) into the first insertion groove (313).

[0188] In one embodiment of the present invention, the first end portion (730) can rotate in a predetermined direction and angle within the first insertion groove (313).

[0189] At this time, the first insertion groove (313) may be formed larger than the first end portion (730). For example, the inner diameter of the first insertion groove (313) may be formed larger than the outer diameter of the first end portion (730). In this case, the first end portion (730) can be rotated in a predetermined direction and angle within the first insertion groove (313).

[0190] Additionally, a first through hole (319) may be formed in the inner wall defining the first insertion groove (313) through which a portion of a wire body (710) communicating with the first insertion groove (313) and connected to the first end portion (730) is positioned to pass.

[0191] In other words, a first through hole (319) communicating with the first insertion groove (313) may be formed in the first protrusion (312) in which the first insertion groove (313) is formed.

[0192] For example, the first through hole (319) can extend in a direction perpendicular to and parallel to one surface of the movable member body (310). The wire body (710) connected to the first end portion (730) is free to move along the first through hole (319) in a direction perpendicular to and parallel to one surface of the movable member body (310), and accordingly, the first end portion (730) can rotate within the first insertion groove (313).

[0193] In this case, the compressive stress applied to the joint portion of the movable member body (310) and the wire (700) due to the irregular movement of the first end portion (730) that may occur depending on the movement of the movable member (300) can be minimized, thereby increasing the lifespan of the wire (700).

[0194] Referring to FIGS. 13, 14 and 18, a second insertion groove (513) into which a second end portion (740) is inserted is formed in the adjusting member body portion (510).

[0195] The second insertion groove (513) can be formed in a second protrusion (512) that has a predetermined width and protrudes on one surface of the adjusting member body (510).

[0196] At least one second catch (513a) may be formed extending toward the center of the second insertion groove (513) on the inner wall defining the second insertion groove (513) to prevent the second end (740) from coming out of the second insertion groove (513).

[0197] In the process of inserting the second end (740) into the second insertion groove (513), the second end (740) or the second catch (513a) is elastically deformed, making it easier to insert the second end (740) into the second insertion groove (513).

[0198] In one embodiment of the present invention, the second terminal portion (740) can rotate in a predetermined direction and angle within the second insertion groove (513).

[0199] At this time, the second insertion groove (513) may be formed larger than the second end portion (740). For example, the inner diameter of the second insertion groove (513) may be formed larger than the outer diameter of the second end portion (740). In this case, the second end portion (740) can be rotated in a predetermined direction and angle within the second insertion groove (513).

[0200] Additionally, a second through hole (519) may be formed through which a portion of the wire body (710) connected to the second terminal (740) is positioned to penetrate.

[0201] The second through hole (519) may extend in a direction perpendicular to one surface of the adjusting member body (510). In this case, the wire body (710) connected to the second end (740) may be free to move in a direction perpendicular to one surface of the adjusting member body (510) along the second through hole (519). However, the second through hole (519) may also extend in a direction parallel to one surface of the adjusting member body (510) like the first through hole (319).

[0202] In this case, the compressive stress applied to the joint portion of the adjusting member body (510) and the wire (700) due to the irregular flow of the second end portion (740) that may occur depending on the flow of the adjusting member (500) can be minimized, so that the lifespan of the wire (700) can be increased.

[0203] 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 will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
