Description

Technical Field

[0001] The present invention relates to a helmet, and more particularly to a helmet which protects the head of a wearer from an external impact when the helmet is worn on the head of the wearer. Background Art

[0002] When an accident occurs, the two-wheeled vehicle lacks a mechanism to protect the passengers, and when an accident occurs, the risk of the impact being directly transmitted to the passengers is very high. Therefore, the passengers of the two-wheeled vehicle must wear a safety helmet for protecting their heads, that is, a helmet.

[0003] In general, a helmet includes: a helmet body that protects the head of a user from external impacts; and a shield that covers and is combined with the open part of the helmet body and has a structure that can be opened and closed up and down by pivoting. The shield is formed of a transparent or translucent raw material, thereby not only ensuring the wearer's field of vision, but also protecting the user's eyes from external wind, foreign objects, etc. In addition to the shield, a sun visor for blocking sunlight can also be combined with the helmet body in a pivotable manner.

[0004] When pivoting to open or close the shield, sun visor and other parts, the existing helmets often interfere with the helmet body or stick to the helmet body on the pivoting path, so that the pivoting cannot be smoothly realized. Therefore, when the user wants to open or close the shield, sun visor and other parts, there is the inconvenience of applying too much force to realize the pivoting, thereby reducing the convenience of use of the helmet.

[0043] Figure 1 FIG. 2 is a diagram showing the structure of a helmet according to an embodiment of the present invention. Figure 2 FIG. 1 is a diagram showing a state in which the pivoting parts of a helmet according to an embodiment of the present invention are separated. Figure 3 FIG. 1 is a diagram showing an enlarged view of a structure related to the pivoting of a pivoting member in a helmet according to an embodiment of the present invention. Figure 4 To express in Figure 3 On the other hand, Figure 5 and Figure 6 The figure shows a state where a fixing member, a moving member, a pivoting member, a pressurizing member, a first elastic member, and a second elastic member of a helmet according to an embodiment of the present invention are disassembled.

[0044] The helmet of one embodiment of the present invention has a structure in which the pivot axis moves forward when the pivoting member 400 pivotally fastened to the helmet body 100 is pivoted from a first position (e.g., a position where the pivoting member 400 closes the opening portion 100a of the helmet body 100) to a second position (e.g., a position where the pivoting member 400 opens the opening portion 100a of the helmet body 100), thereby preventing interference between the helmet body 100 and the pivoting member 400 during the pivoting process of the pivoting member 400. Therefore, the present invention can smoothly realize the pivoting of the pivoting member 400, thereby improving the practicality of the helmet.

[0045] Reference Figures 1 to 6 A helmet according to an embodiment of the present invention includes a helmet body 100 , a fixing component 200 , a moving component 300 , a pivoting component 400 , a pressurizing component 500 , a first elastic component 600 , and a second elastic component 700 .

[0046] The helmet body 100 can wrap the head of the user. The helmet body 100 is worn on the head of the user to protect the head of the user from external impact. In one embodiment of the present invention, the helmet body 100 can have an open portion 100a in the front part to ensure the user's field of vision.

[0047] The helmet body 100 is formed of a raw material that can absorb shock. For example, the helmet body 100 may include: an outer shell formed of a hard synthetic resin or the like and having high strength; and a shock absorber disposed inside the outer shell. In this case, the shock absorber may be formed of expanded polystyrene (EPS) or the like.

[0048] The fixing component 200 is fixed to the side of the helmet body 100. The moving component 300 is combined with the fixing component 200 in a manner that it can be linearly displaced forward and backward. In one embodiment of the present invention, a fixing component 200 can be disposed on the left and right sides of the helmet body 100, respectively.

[0049] like Figures 5 and 6 As shown most clearly, the fixing component 200 may include a fixing body 210 , a cam placement portion 220 , a pressing component configuration portion 230 , a pivot guide portion 240 , a pivot assist portion pivot portion 250 , a pressing portion pivot portion 260 , a first support portion 270 and a moving component fastening portion 280 .

[0050] The fixing body 210 is fastened to the helmet body 100. The fixing body 210 may be in a plate shape. The inner side of the fixing body 210 is arranged to face the helmet body 100, and the outer side is arranged to face the outside. Hereinafter, the inner side means a side relatively close to the helmet body 100 or looking toward the helmet body 100, and the outer side means a side relatively far from the helmet body 100 or looking toward the outside of the helmet body 100.

[0051] When the moving part 300 described later moves backward, the front upper end 210a and the front lower end 210b of the fixed body 210 act as a stopper and limit the moving range of the moving part 300. In one embodiment of the present invention, the fixed body 210 may have a protrusion 210c, which is inserted into the window part 320 provided in the moving part 300 and protrudes inward from the inner side surface of the fixed body 210 to guide the linear movement of the moving part 300. The protrusion 210c may be arranged in contact with the upper side corner and the lower side corner of the window part 320, and limit the vertical movement of the moving part 300.

[0052] The cam placement portion 220 is recessed and formed in the fixed body 210 so as to place the cam 420 of the pivoting member 400. The cam 420 becomes the pivot of the pivoting member 400. The cam 420 of the pivoting member 400 can be pivotally placed on the cam placement portion 220. With respect to the cam placement portion 220, when the pivoting member 400 is pivoted from the first position to the second position, the cam 420 of the pivoting member 400 is displaced toward the front, thereby providing a profile that allows the pivot to be displaced toward the front.

[0053] In one embodiment of the present invention, the cam placement portion 220 includes: a cam placement surface 221, which is provided in a manner of contacting at least a portion of the inner surface of the cam 420; a first support surface 222, which is provided by a side wall extending in the up-down direction at the rear of the cam placement surface 221; a second support surface 223, which is provided by a side wall inclined downward from the rear to the front at the rear of the upper part of the cam placement surface 221; a third support surface 224, which is provided by a side wall inclined upward from the rear to the front at the front of the upper part of the cam placement surface 221; and a fourth support surface 225, which is provided by a side wall that is sunken downward in an arc shape at the lower part of the cam placement surface 221.

[0054] The pressure component configuration part 230 is disposed in front of the cam placement part 220 so as to configure a pressure component 500 for providing an elastic support force to the cam 420 configured in the cam placement part 220. In one embodiment of the present invention, the pressure component configuration part 230 may include: a pressure component configuration groove 231, which is formed by penetrating the outer side and the inner side of the fixed body 210 in front of the cam placement part 220; a cover bridge 232, which penetrates the pressure component configuration groove 231 in an upward direction and is configured integrally with the fixed body 210 so as to cover the outer side of the pressure component 500 in order to prevent the pressure component 500 configured in the pressure component configuration groove 231 from being separated; and a first elastic component configuration groove 233, which is used to place a first elastic component 600, which pressurizes the pressure component 500 backward and provides an elastic support force.

[0055] like Figure 6 As shown, the cover bridge 232 may be arranged to penetrate the press member arrangement groove 231 in an upward direction so as to cover the outside of the press member 500. The cover bridge 232 is arranged to lock the locking portion 520 of the press member 500 described later and restrict the press member 500 from moving forward.

[0056] The first elastic member arrangement groove 233 supports the front end of the first elastic member 600 and covers at least a portion of the outer side surface of the first elastic member 600 so that the first elastic member 600 is detached outward. At this time, the rear end of the first elastic member 600 can be supported by the pressurizing member 500 .

[0057] The pivot guide portion 240 provides a pivot profile of the pivot member 400 and is disposed in front of the fixed member 200. In one embodiment of the present invention, the pivot guide portion 240 provides a pivot path of the pivot guided portion 430 when the pivot member 400 pivots, and guides the pivoting of the pivot member 400. The pivot guide portion 240 may be disposed on the front wall of the fixed body 210. In this case, the front wall may be in an arch shape with the central portion convex toward the front. In other words, the pivot profile may be in an arch shape with the central portion convex toward the front.

[0058] The pivoting part 250 of the pivoting auxiliary part is formed by penetrating the outer side and the inner side of the fixed body 210 at the rear of the cam placement part 220. The pivoting auxiliary part 440 of the pivoting part 400 and the second pivoting support part 350 of the moving part 300 meshed with the pivoting auxiliary part 440 are arranged on the pivoting auxiliary part 250. When the pivoting part 400 is pivoted, the pivoting auxiliary part 440 can be pivoted inside the pivoting auxiliary part 250, and the second pivoting support part 350 of the moving part 300 can be linearly moved. In this regard, the front part of the pivoting auxiliary part 250 can play the role of a stopper for limiting the front displacement of the moving part 300.

[0059] When the pivoting member 400 is pivoted, the pressurizing portion pivoting portion 260 provides a pivoting path for the pressurizing portion 450. In one embodiment of the present invention, the pressurizing portion pivoting portion 260 includes a pressurizing portion pivoting groove 261, which penetrates the outer side and the inner side of the fixed body 210 at the lower side of the cam placement portion 220. The pressurizing portion pivoting groove 261 may be in an arch shape protruding toward the lower side. In addition, the pressurizing portion 450 of the pivoting member 400 may be in a hook shape with the inner end protruding toward the lower side, and the pressurizing portion pivoting groove 261 may have a portion 261a with a penetration area expanding toward the lower side in the front part, so that the pressurizing portion 450 can be entered or separated. In other words, the pressurizing portion pivot slot 261 can allow the pressurizing portion 450 to enter into or separate from the pressurizing portion pivot slot 261 through the expanded portion 261a, and the remaining portion can engage with the pressurizing portion 450 when the pivoting component 400 pivots.

[0060] On the other hand, in one embodiment of the present invention, the pressure-applying portion pivoting portion 260 further includes a height difference 262, which is provided at least one of the upper side and the lower side of the pressure-applying portion pivoting groove 261 in the inner side surface of the fixed body 210. The height difference 262 has a structure in which the rear portion protrudes further inward than the front portion. If the fixing mechanism 360 of the moving part 300 described later is stuck in the height difference 262, the moving part 300 becomes fixed relative to the fixed part 200, and the linear displacement is restricted.

[0061] The first support portion 270 supports the front side of the second elastic member 700 which is disposed between the fixed member 200 and the movable member 300 and presses the movable member 300 backward. In one embodiment of the present invention, the first support portion 270 may be disposed on the upper side of the cam placement portion 220. In more detail, the first support portion 270 may include: an elastic member configuration groove 271 extending in the front-rear direction so that the second elastic member 700 may be configured, and penetrating the outer side and the inner side of the fixed body 210; and a first support wall 272 disposed in front of the elastic member configuration groove 271 so as to support the front end of the second elastic member 700.

[0062] The moving part fastening portion 280 is provided to improve the fastening force between the fixed part 200 and the moving part 300. The moving part fastening portion 280 may include: a fastening groove 281 extending in the front-rear direction and penetrating the outer side and the inner side of the fixed body 210; and a first fastening hook 282 extending from the side wall of the fastening groove 281 to the inner side of the fastening groove 281. When the fixed part 200 fastens the moving part 300, the second fastening hook 382 of the moving part 300 described later may be engaged with the first fastening hook 282 and arranged inside the fastening groove 281. When the moving part 300 performs linear displacement, the second fastening hook 382 of the moving part 300 may perform linear displacement in the front-rear direction inside the fastening groove 281.

[0063] On the other hand, the fixing member 200 may have one or more fastening parts for fastening a fastening member S (e.g., a screw) for combining the fixing member 200 with the helmet body 100. In one embodiment of the present invention, the fixing member 200 has a first fastening part 211, a second fastening part 212, and a third fastening part 213 that respectively penetrate the front upper end 210a, the front lower end 210b, and the cam placement surface 221 of the fixing body 210.

[0064] The moving part 300 is combined with the fixing part 200 in a manner that it can linearly move forward and backward. When the pivoting part 400 pivots, the moving part 300 moves forward or backward, and the pivot can move forward or backward.

[0065] like Figures 5 and 6 Most obviously, the moving component 300 may include a moving body 310 , a window portion 320 , a second support portion 330 , a first pivot support portion 340 , a second pivot support portion 350 , a fixing mechanism 360 and a handle portion 370 .

[0066] The moving body 310 is fastened to the fixed part 200 in a manner that it can move forward and backward. The moving body 310 may be in the shape of a plate. The moving body 310 is disposed on the inner side of the fixed part 200. In one embodiment of the present invention, the moving body 310 has a front upper end portion 310a protruding outward from the front upper end and a front lower end portion 310b protruding outward from the front lower end. The front upper end portion 310a and the front lower end portion 310b of the moving body 310 are respectively disposed at positions corresponding to the front upper end portion 210a and the front lower end portion 210b of the fixed body 210, and the rearward displacement of the moving part 300 is limited.

[0067] The window portion 320 penetrates the outer side and the inner side of the movable body 310 and extends in the front-back direction so as to be inserted into the protrusion 210c of the fixed body 210. As described above, the protrusion 210c protrudes inwardly from the inner side of the fixed body 210. The upper side corner and the lower side corner of the window portion 320 can be arranged in contact with the protrusion 210c, thereby, when the movable member 300 moves in the front-back direction, the movement in the up-down direction can be restricted.

[0068] The second support portion 330 supports the rear side of the second elastic component 700 which is arranged between the fixed component 200 and the movable component 300 and pressurizes the movable component 300 to the rear. In one embodiment of the present invention, the second support portion 330 may be arranged on the upper side of the window portion 320. In more detail, the second support portion 330 may include: an elastic component arrangement groove 331 extending in the front-rear direction so that the second elastic component 700 can be arranged and the movable body 210 is placed; and a second support wall 332 protruding outwardly from the rear of the elastic component arrangement groove 331 so as to support the rear end of the second elastic component 700.

[0069] The first pivot support portion 340 is engaged with the pivoting guided portion 430 of the pivoting member 400 so as to prevent the pivoting member 400 from being disengaged when the pivoting member 400 is pivoted. In one embodiment of the present invention, the pivoting guided portion 430 may be a hook protruding inwardly from the inner side of the pivoting body 410. The first pivot support portion 340 may be provided as an arched wall protruding outwardly so as to engage with the pivoting guided portion 430 guided and displaced by the pivoting guide portion 240 of the fixing member 200 when the pivoting member 400 is pivoted. Furthermore, the first pivot support portion 340 may be arranged in front of the pivoting guide portion 240 of the fixing member 200, and together with the pivoting guide portion 240, form a groove for the pivoting guided portion 430 to move, and may be connected to the front of the moving body 310 so as to engage with the pivoting guided portion 430. In more detail, the rear portion of the first pivot support portion 340 may have a shape in which the outer side extends further rearward than the inner side so that the hook-shaped pivot guided portion 430 may be engaged.

[0070] The second pivot support portion 350 is configured to be engaged with the pivot auxiliary portion 440 of the pivot member 400, thereby increasing stability when the pivot member 400 is pivoted. The pivot auxiliary portion 440 may be a hook protruding inwardly from the inner side of the pivot body 410. The second pivot support portion 350 may be provided as an arched wall protruding outwardly so that the pivot auxiliary portion 440 is engaged. In one embodiment of the present invention, the second pivot support portion 350 may be configured at the rear of the mobile body 310, and the rear portion of the second pivot support portion 350 may be shaped such that the outer side extends further rearwardly than the inner side so that the hook-shaped pivot auxiliary portion 440 is engaged.

[0071] The fixing mechanism 360 is provided so as to fix the moving part 300 when the moving part 300 reaches a predetermined position in front relative to the fixing part 200. The fixing mechanism 360 may be provided so that at least a part of the moving part 300 protrudes outward due to elasticity when the moving part 300 moves forward and reaches a predetermined position. The fixing mechanism 360 may be provided as a plate-shaped spring at least a part of which protrudes outward at the lower side of the window part 320 due to elasticity. In more detail, the fixing mechanism 360 may be provided in an integral manner on the moving body 310.

[0072] Before the moving part 300 reaches the prescribed position in the front, the fixing mechanism 360 maintains the state of being pressed by the inner side surface of the fixed body 210 located behind the height difference 262 of the pressurizing part pivoting part 260, and the moving part 300 can be reversibly displaced toward the front or rear. However, when the moving part 300 reaches the prescribed position in the front, the pressurized state of the fixing mechanism 360 is released, and the fixing mechanism 360 protrudes outward and is stuck at the height difference 262. Thus, the displacement of the moving part 300 toward the rear is restricted. At this time, the prescribed position can become a position for realizing the connection or separation of the pivoting part 400.

[0073] In one embodiment of the present invention, the fixing mechanism 360 includes: a plate-shaped first portion 361, the front end of which is connected to the moving body 310 and protrudes outward as it approaches the rear; and a plate-shaped second portion 362, which is connected to the rear of the first portion 361 and tilts inward as it approaches the rear. In the process of combining with the pivoting member 400, when the fixing mechanism 360 is pressurized inwardly by the pressurizing portion 450 of the pivoting member 400, the second portion 362 improves the reliability of operation. In addition, the fixing mechanism 360 may further include a fixing protrusion 363, which further protrudes outward at the boundary between the first portion 361 and the second portion 362. When the pressurized state of the fixing mechanism 360 is released, the fixing protrusion 363 is stuck in the height difference 262. The fixing protrusion 363 improves the reliability of operation when the moving member 300 is fixed.

[0074] The handle portion 370 may be provided to extend forward at the lower portion of the mobile body 310. In one embodiment of the present invention, when the pivoting member 400 pivots to the second position and the mobile member 300 is displaced to a predetermined position in the front, the pivoting member 400 may be separated from the mobile member 300. In this regard, the mobile member 300 has a fixing mechanism 360, and when the mobile member 300 moves forward, the fixing mechanism 360 fixes the mobile member 300. When the user moves the mobile member 300 to the predetermined position in the front, the handle portion 370 is provided so that a force toward the front can be easily applied to the mobile member 300.

[0075] The pivoting member 400 is pivotally placed on the cam placement portion 220 of the fixed member 200 and is pivotally coupled to the movable member 300. In one embodiment of the present invention, the pivoting member 400 may be a shield, a mask, etc. that can open and close the opening portion 100a of the helmet body 100.

[0076] The pivoting member 400 includes a cam 420 pivotally mounted on the cam mounting portion 220, and is configured to pivotally engage with the moving member 300 with the cam 420 as a pivot. In more detail, the pivoting member 400 may include a pivoting body 410, a cam 420, a pivoting guided portion 430, a pivoting auxiliary portion 440, and a pressing portion 450.

[0077] The pivot body 410 is a part for opening and closing the opening portion 100a of the helmet body 100. The pivot body 410 can be provided in a transparent or translucent manner. For example, the pivot body 410 can form a shield, a mask, etc.

[0078] The cam 420 protrudes inwardly from the inner side surface of the side portion of the pivot body 410. In one embodiment of the present invention, a pair of cams 420 may be provided on both sides of the pivot body 410. The cam 420 functions as a pivot of the pivot member 400. The cam 420 is pivotably disposed in the cam placement portion 220 of the fixing member 200, and has a profile that can be displaced forward when the pivot member 400 pivots from the first position to the second position.

[0079] The cam 420 has a triangular shape including a first corner portion 420a, a second corner portion 420b, and a third corner portion 420c. A first cam surface 421 is provided between the first corner portion 420a and the second corner portion 420b, a second cam surface 422 is provided between the second corner portion 420b and the third corner portion 420c, and a third cam surface 423 is provided between the third corner portion 420c and the first corner portion 420a. When the cam 420 is pivoted on the cam placement portion 220 of the fixing member 200, this structure of the cam 420 provides a profile that allows the pivot to be displaced in the front and rear directions.

[0080] In one embodiment of the present invention, the first corner portion 420a, the second corner portion 420b and the third corner portion 420c of the cam 420 can protrude toward the cam placement surface 221 so as to contact the cam placement surface 221 of the cam placement portion 220, and the first corner portion 420a and the second corner portion 420b, the second corner portion 420b and the third corner portion 420c, and the third corner portion 420c and the first corner portion 420a are not in contact with the cam placement surface 221. With this structure, when the cam 420 is pivoted, the cam placement surface 221 and the cam 420 can not only ensure a stable contact surface, but also minimize the contact area, so that the pivoting of the cam 420 can be achieved more stably.

[0081] When the pivoting member 400 rotates with the cam 420 as the pivot axis, the pivoting guided portion 430 is guided by the pivoting guide portion 240 of the fixed member 200. In one embodiment of the present invention, the pivoting guided portion 430 may be a protrusion protruding inward from the inner surface of the pivoting body 410 in front of the cam 420. In more detail, the pivoting guided portion 430 may be in the shape of a hook that engages with the first pivoting support portion 340 of the moving member 300. When the pivoting member 400 pivots, the pivoting guided portion 430 may move forward or backward together with the first pivoting support portion 340 of the moving member 300 while being engaged with the first pivoting support portion 340 of the moving member 300.

[0082] The pivot assisting portion 440 is provided to improve the pivoting stability of the pivoting member 400. In one embodiment of the present invention, the pivot assisting portion 440 is disposed at a position spaced a predetermined distance rearward from the pivoting guided portion 430. In more detail, the pivot assisting portion 440 may be a protrusion protruding inward from the inner surface of the pivoting body 410 behind the cam 420. The pivot assisting portion 440 may be in the shape of a hook that engages with the second pivoting support portion 350 of the moving member 300. When the pivoting member 400 is pivoted, the pivot assisting portion 440 may move forward or backward together with the second pivoting support portion 350 of the moving member 300 while being engaged with the second pivoting support portion 350 of the moving member 300.

[0083] In the state where the moving part 300 is fixed by the fixing mechanism 360, when the pivoting part 400 is combined with the moving part 300, the pressurizing part 450 releases the fixed state of the moving part 300 caused by the fixing mechanism 360, and pressurizes the fixing mechanism 360 toward the helmet body 100 side, so that the pivoting guided part 430 and the first pivoting support part 340 are engaged. In one embodiment of the present invention, the pressurizing part 450 can be a protrusion protruding from the inner surface of the pivoting body 410 on the lower side of the cam 420. In more detail, the pressurizing part 450 can enter the pressurizing part pivoting groove 261 through the expanded part 261a of the pressurizing part pivoting groove 261 of the fixing part 200, and pressurize the fixing mechanism 360 to release the stuck state between the fixing mechanism 360 and the height difference 262, and in the pivoting process of the pivoting part 400, it pivots in a state of being engaged with the pressurizing part pivoting groove 261.

[0084] The pressurizing member 500 is configured in a manner to elastically support the cam 420 on the fixing member 200, and pressurizes the cam 420 backward. The pressurizing member 500 is configured on the pressurizing member configuration portion 230 of the fixing member 200, and pressurizes the cam 420 backward, realizes the pivoting of the cam 420 inside the cam placement portion 220, and pressurizes the cam 420 when the pivot moves forward or backward, so that the cam 420 can be stably operated in the cam placement portion 220. In one embodiment of the present invention, the pressurizing member 500 can receive elastic force from the first elastic member 600.

[0085] The pressurizing component 500 may include a pressurizing body 510, which is arranged inside the pressurizing component configuration groove 231 and supported on the outside by the cover bridge 232. The rear side wall of the pressurizing body 510 contacts the cam 420. In addition, the front side wall of the pressurizing body 510 is supported by the first elastic component 600 configured in the first elastic component configuration groove 233 of the fixing component 200. In addition, the rear side wall of the pressurizing body 510 may be inclined downward from the front toward the rear. This shape is in consideration of the pivoting profile of the cam 420, and when pivoting from the first position to the second position, the support of the cam 420 can be performed more stably.

[0086] The pressurizing component 500 may further include a locking portion 520 that protrudes outward from the rear portion of the pressurizing body 510. When the pressurizing component 500 is pressurized forward by the cam 420 and moves forward, the locking portion 520 may be formed in a manner of being locked in the cover bridge 232, and determines the displacement limit of the pressurizing component 500, and provides displacement stability to the pressurizing component 500.

[0087] The first elastic member 600 is disposed between the fixing member 200 and the pressurizing member 500, and elastically supports the pressurizing member 500. In one embodiment of the present invention, the first elastic member 600 may be inserted into the first elastic member configuration groove 233 of the fixing member 200. At this time, the front end of the first elastic member 600 may be supported by the first elastic member configuration groove 233, and the rear end of the first elastic member 600 may be supported by the pressurizing member 500. For example, the first elastic member 600 may be formed by a coil spring.

[0088] The second elastic member 700 is disposed between the fixed member 200 and the movable member 300, and presses the movable member 300 backward. In one embodiment of the present invention, the front side of the second elastic member 700 is supported by the first support portion 270 of the fixed member 200, and the rear side of the second elastic member 700 is supported by the second support portion 330 of the movable member 300. For example, the second elastic member 700 may be formed of a coil spring.

[0089] As described above, according to the present invention, the first elastic member 600 elastically supports the cam 420 of the pivoting member 400 via the pressurizing member 500, and the second elastic member 700 presses the moving member 300 backward, so that the elastic support for the pivot of the pivoting member 400 and the elastic support for the moving member 300 can be independently performed by additional members. This structure can independently distribute and provide the pressurizing force of the cam 420 required for stabilizing the pivot when the cam 420 pivots, and the pressurizing force required for properly maintaining the engagement between the pivoting member 400 and the moving member 300 when the pivot moves forward or backward. As a result, the use feeling, stability and reliability related to the pivoting of the pivoting member 400 can be improved.

[0090] Hereinafter, the pivoting of the pivoting member 400 in the helmet according to an embodiment of the present invention and the installation and removal of the pivoting member 400 will be described.

[0091] Figure 7 FIG. 1 is a diagram showing a process in which a pivoting member of a helmet according to an embodiment of the present invention pivots from a first position to a second position. Figure 7 The pivot body 410 of the pivot member 400 is omitted.

[0092] Reference Figure 7, the pivoting member 400 can pivot from the first position to the second position. At this time, the first position can be a state where the pivoting member 400 closes the open portion 100a of the helmet body 100, which is represented by "0 degrees" based on the pivoting angle. And, the second position can be a state where the pivoting member 400 is fully open, which is represented by "55 degrees". When the pivoting member 400 pivots from the first position to the second position, the pivot moves forward in at least a portion of the interval, and the pivoting member 400 and the moving member 300 are displaced forward.

[0093] Reference Figure 4 , Figure 5 and Figure 7 When the pivoting member 400 is located at the first position, in the cam 420, the first cam surface 421 between the first corner portion 420a and the second corner portion 420b can be supported by the first support surface 222 on the rear side of the cam placement portion 220, and the third corner portion 430c can contact the pressing member 500. When the pivoting member 400 pivots from the first position to the second position, the first cam surface 421 is separated from the first support surface 222, the first corner portion 420a of the cam 420 contacts the first support surface 222 and moves downward, the second corner portion 420b of the cam 420 contacts the fourth support surface 225 and moves, and the third corner portion 420c contacts the rear side of the pressing member 500 and moves upward. Also, when the pivoting member 400 is located at the second position, in the cam 420 , the second cam surface 422 between the second corner portion 420 b and the third corner portion 420 c may contact the pressing member 500 , and the first corner portion 420 a may contact the first supporting surface 222 .

[0094] In one embodiment of the present invention, the cam 420 of the pivoting member 400 is always pressed backwards by the pressing member 500 inside the cam placement portion 220. Thus, at any position between the first position and the second position, the cam 420 is always supported by the support surface of the cam placement portion 220 and the pressing member 500. Thus, when the pivoting member 400 is pivoted, the pivoting path corresponding to the pivoting profile designed with the cam 420 is maintained, and when pivoting, the usability and the reliability of the pivoting can be ensured.

[0095] In one embodiment of the present invention, according to the pivoting profile provided by the cam 420 and the cam placement portion 220, the pivot moves forward until the pivoting member 400 reaches the second position from the first position. Generally, in the structure of the helmet, when the pivoting member 400 is pivoted, it may cause interference with the helmet body 100, and during the pivoting process, the pivot moves forward, thereby avoiding interference between the pivoting member 400 and the helmet body 100, so that the pivoting member 400 can be pivoted softly and smoothly.

[0096] On the other hand, with respect to the pivoting profile provided by the cam 420 of the pivoting member 400 and the cam placement portion 220 of the fixing member 200, when the pivoting member 400 is pivoted, the pivot can move downward or upward to a predetermined position, and when further pivoting at the predetermined position, the pivot can move upward or downward. This structure and operation can also avoid interference between the helmet body 100 or an attachment of the helmet body 100 and the pivoting member 400.

[0097] In one embodiment of the present invention, with respect to the pivoting profile provided by the cam 420 of the pivoting member 400 and the cam placement portion 220 of the fixed member 200, until the predetermined position (for example, the pivoting angle is 27.5 degrees) is reached from the first position, the third cam surface 423 of the cam 420 descends from the rear to the front along the second support surface 223 of the cam placement portion 220 which is inclined downward. Thus, until the cam 420 pivots from the first position to the predetermined position, the pivot moves forward and moves downward. Furthermore, with respect to the pivoting profile provided by the cam 420 of the pivoting member 400 and the cam placement portion 220 of the fixed member 200, until the second position is reached from the predetermined position, the third cam surface 423 of the cam 420 ascends from the rear to the front along the third support surface 224 of the cam placement portion 220 which is inclined upward. Thus, until the cam 420 reaches the second position at 30 degrees, the pivot moves forward and moves upward.

[0098] On the other hand, during the entire process of the pivoting member 400 pivoting from the first position to the second position, the pivoting guide portion 430, the pivoting auxiliary portion 440 and the pressing portion 450 of the pivoting member 400 are engaged and supported by the first pivoting support portion 340, the second pivoting support portion 350 and the pressing portion pivoting portion 260. Thus, the pivoting member 400 can be prevented from being disengaged and the pivoting member 400 can be pivoted stably.

[0099] Through the structure and operation as described above, during the pivoting process of the pivoting component 400 , the pivoting component 400 may not interfere with the helmet body 100 , and may pivot softly and smoothly.

[0100] Figure 8 FIG. 4 is a diagram showing the separation process of the pivoting component of the helmet according to the embodiment of the present invention. Figure 8 The pivot body 410 of the pivot member 400 is omitted.

[0101] Reference Figure 3 , Figure 4 and Figure 8In the helmet of the embodiment of the present invention, when the movable part 300 reaches the prescribed position in the front relative to the fixed part 200 at the second position (in the embodiment of the present invention, the pivot angle is "55 degrees"), the engagement between the pivoting guided part 430 and the first pivoting support part 330 is released, and the pivoting part 400 can be separated. In the second position, when the movable part 300 reaches the prescribed position in the front relative to the fixed part 200, the engagement between the pivoting auxiliary part 440 of the pivoting part 400 and the second pivoting support part 350 of the movable part 300 can also be released. In addition, the pressurizing part 450 is also located at the expanded part 261a of the pressurizing part pivoting groove 261 of the pressurizing part pivoting part 260, so that the engagement between the second pivoting support part 350 and the pressurizing part pivoting part 260 of the fixed part 200 can be released.

[0102] As described above, in the second position, when the movable part 300 reaches the predetermined position forward relative to the fixed part 200, the fixing mechanism 360 of the movable part 300 can be caught in the height difference 262 of the fixed part 200, and the fixed movable part 300 can be fixed. Furthermore, when the pivoting part 400 is engaged, the pressing part 450 presses the fixing mechanism 360 inward to release the stuck state between the height difference 262 and the fixing mechanism 360, thereby eliminating the fixed state of the movable part 300.

[0103] An embodiment of the present invention is described above, but the concept of the present invention is not limited to the embodiment proposed in this specification. Those skilled in the art who understand the concept of the present invention can easily propose other embodiments within the scope of the same concept by adding, changing, deleting, and appending structural elements, and these also fall within the scope of the concept of the present invention.
