(14) However, according to this embodiment, when the opening of the head frame 1 is opened by turn up the face frame, the sun visor 100 is turned up with the face frame in the early stage, as shown in FIG. 2, but when a predetermined rotational limit is reached, the sun visor 100 is fixed regardless of rotation of the face frame, as shown in FIG. 3.

(15) That is, according to the helmet of this embodiment, when the face frame is opened, the sun visor 100 is turned with the face frame to the rotational limit, but the sun visor 100 is fixed and only the face frame can be turned after the rotational limit.

(16) The structure of the rotation parts 10 is described in detail hereafter.

(17) FIG. 4 is an exploded view of the helmet according to an embodiment of the present invention.

(18) As shown in FIG. 4, the helmet according to an embodiment of the present invention includes the head frame 1, the sun visor 100, the glass shield 200, and the chin guard 300.

(19) First rotary coupling portions 110, second rotary coupling portions 210, and third rotary coupling portions 310 are formed at the sun visor 100, the glass shield 200, and the chin guard 300, respectively, and they are coupled to the rotation part 10 (see FIG. 1) at both sides of the head frame 1.

(20) That is, the sun visor 100, the glass shield 200, and the chin guard 300 share the same rotational axis, and the first rotary coupling portions 110, second rotary coupling portions 210, and the third rotary coupling portions 310 can be operated in cooperation with each other.

(21) On the other hand, according to this embodiment, the rotation parts 10 each includes a first rotation-assisting member 400 and a second rotation-assisting member 500, and the rotation-assisting members assist rotation of the sun visor 100, the glass shield 200, and the chin guard 300.

(22) In particular, in this embodiment, the second rotation-assisting members 500 are fixed in seats 5 formed on both sides of the head frame 1 and the first rotation-assisting members 400 are rotated with rotation of the chin guard 300. Chin guard support 7 for supporting the chin guard 300 may be further formed on the head frame 1.

(23) A first bolts 50 and a second bolt 52 for fixing the sun visor 100, the glass shield 200, the chin guard 300, the first rotation-assisting members 400, and the second rotation-assisting members 500 may be disposed in the rotation part 10 through them. The first bolt 50 and the second bolt 52 are disposed through the position of the rotational axis of the components of the rotation part 10 and rotatably fix the components.

(24) FIGS. 5 and 6 are views showing in detail the structure of the rotation part 10 in the helmet according to an embodiment of the present invention.

(25) As shown in FIGS. 5 and 6, the second rotation-assisting member 500, the third rotary coupling portion 310, the first rotation-assisting member 400, the second rotary coupling portion 210, and the first rotary coupling portion 110 are sequentially arranged from the inside in the rotation part 10

(26) In the detailed structure, a first sun visor stopper 112 protruding inward is formed on the first rotary coupling portion 110.

(27) A first hole 212, a glass shield anti-rotational hole 214, a glass shield-rotational projection 216, and a first glass shield stopper 218 are formed at the second rotary coupling portion 210.

(28) A glass shield anti-rotational projection 402, a second hole 404, a glass shield rotation guide 306, and a chin guard anti-rotational projection 408 are formed at the first rotation-assisting member 400.

(29) A through-hole-312 is formed through the third rotary coupling portion 310.

(30) A second glass shield stopper 502, a second sun visor stopper 504, and a chin guard anti-rotational hole 506 are formed at the second rotation-assisting member 500.

(31) The first sun visor stopper 112 protrudes through the first hole 212 and the second hole 404, and the first hole 212 and the second hole 404 are arc-shaped slots, so the first sun visor stopper 112 can move within a predetermined range defined by the first hole 212 and the second hole 404.

(32) The movement range of the first sun visor stopper 112 may be the rotational range of the sun visor 100.

(33) The outer circumference 311 of the third rotary coupling portion 310 is formed to corresponding to the position of the inner circumference of the second hole 404 and the first sub visor stopper 112 is positioned outside the outer circumference 311 of the third rotary coupling portion 310.

(34) The maximum movement range of the first sun visor stopper 112 may be limited by the second sun visor stopper 504 on the second rotation-assisting member 500.

(35) That is, the first sun visor stopper 112 is positioned farthest from the second sun visor stopper 504 when the sun visor 100 has been turned down, and gradually approaches the second sun visor stopper 504 when the sun visor 100 is turned up. Further, when the first sun visor stopper 112 comes in contact with the second sun visor stopper 504, rotation of the sun visor 100 is restricted.

(36) Meanwhile, as described above, the first hole 212 and the second 404 are arc-shaped slots, and in this embodiment, the second hole 404 is longer than the first hole 219.

(37) This is for the first glass shield stopper 218 formed close to an end of the first hole 212 to be inserted and the first glass shield stopper 218 is moved in the second hole 404 within a predetermined range defined by the second hole 404.

(38) The movement range of the first sun visor stopper 112 may

(39) The second glass shield stopper 502 is formed on the second rotation-assisting member 500, so the movement range of the first glass shield stopper 218 can be limited. That is, the first glass shield stopper 218 and the second glass shield stopper 502 limit the rotational range of the entire face frame including the glass shield 200 and the chin guard 300.

(40) In this embodiment, the rotational ranges of the glass shield 200 and the chin guard 300 are made wider than the rotational range of the sub visor 100. Accordingly, when a user opens the face frame, the sun visor 100 is turned with the glass shield 200 and the chin guard 300 in the early stage and is then fixed without turning any more after the first sun visor stopper 112 comes in contact with the second sun visor stopper 504, and thereafter, the glass shield 200 and the chin guard 300 are further turned until the first glass shield stopper 218 and the second glass shield stopper 502 come in contact with each other.

(41) Accordingly, in this embodiment, the sun visor 100 is turned up with the face frame when the opening of the head frame 1 is opened by turning up the face frame, and can be fixed regardless of rotation of the face frame when a predetermined rotational limit is reached, that is, the first sub visor stopper 112 comes in contact with the second sun visor stopper 504.

(42) Meanwhile, the glass shield anti-rotational hole 214 and the glass shield-rotational projection 216 of the second rotary coupling portion 210 and the glass shield anti-rotational projection 402 and the glass shield rotation guide 406 of the first rotation-assisting member 400 are components relating to independent rotation of the glass shield 200.

(43) The glass shield-rotational projection 216 protrudes toward the first rotation-assisting member 400 and is inserted in the glass shield rotation guide 406. The glass shield rotation guide 406 extends to guide the glass shield-rotational projection 216, and particularly in this embodiment, the glass shield rotation guide 406 has prominences and depressions.

(44) Accordingly, the glass shield-rotational projection 216 can be moved step by step over the prominences and depressions of the glass shield rotation guide 406, and accordingly, it is possible to adjust the amount of opening of the glass shield 200 in accordance with the position of the glass shield-rotational projection 216.

(45) The glass shield anti-rotational projection 402 is inserted in the glass shield anti-rotational hole 214 that is an arc-shaped slot, so the glass shield anti-rotational projection 402 can move within a range limited to the range of the glass shield anti-rotational hole 214. That is, the movement range of the glass shield anti-rotational projection 402 may be the rotational range of the glass shield 200.

(46) The chin guard anti-rotational projection 408 of the first rotation-assisting member 400, the through-hole 312 of the third rotary coupling portion 310, and the chin guard anti-rotational hole 506 of the second rotation-assisting member 500 are components relating to independent rotation of the chin guard 300.

(47) The chin guard anti-rotational projection 408 protrudes toward the second rotation-assisting member 500 and is inserted in the chin guard anti-rotational hole 506 through the through-hole 312.

(48) The chin guard anti-rotational hole 506 is an arc-shaped slot and the chin guard anti-rotational projection 408 can move within a range limited to the length of the chin guard anti-rotational hole 506. That is, the movement range of the chin guard anti-rotational projection 408 may be the rotational range of the chin guard 300.

(49) As described above, according to the present invention, independent rotational ranges and cooperative rotational ranges of the components are achieved by close connection among the second rotation-assisting member 500, the rotary coupling portion 310, the first rotation-assisting member 400, the second rotary coupling portion 210, and the first rotary coupling portion 110.

(50) The process of opening the face frame is described again hereafter with reference to FIGS. 7 to 10.

(51) First, as shown in FIG. 7, the second rotation-assisting member 500 is placed and fixed in the seat 5 of the head frame 1. That is, the second rotation-assisting member 500 is fixed without rotating, and the third rotary coupling portion 310, the first rotation-assisting member 400, the second rotary coupling portion 210, and the first rotary coupling portion 110 can be rotated relative to the second rotation-assisting member 500.

(52) When the face frame is closed to cover the opening of the head frame 1, as shown in FIG. 8, the distance between the first sun visor stopper 112 and the second sun visor stopper 504 and the distance between the first glass shield stopper 218 and the second glass shield stopper 502 in the second through-hole 404 are the maximum.

(53) The distance between the first glass shield stopper 218 and the second glass shield stopper 502 is larger than the distance between the first sun visor stopper 112 and the second sun visor stopper 504.

(54) When the face frame is opened in this state, the face frame and the sun visor 100 are turned together in the early stage, and as shown in FIG. 9, the first sun visor stopper 112 and the first glass shield stopper 218 are moved in the second through-hole 404.

(55) Accordingly, the first glass shield stopper 218 and the second glass shield stopper 502 come in contact with each other, and the sun visor 100 is fixed without turning any more at the rotational limit.

(56) Thereafter, as shown in FIG. 10, when the face frame is further turned up, it can move further moved until the first glass shield stopper 218 comes in contact with the second glass shield stopper 502, and the face frame stops turning at the moment that the first glass shield stopper 218 comes in contact with the second glass shield stopper 502.

(57) As described above, when the opening of the head frame is opened by turning up the face frame, the sun visor is turned up with the face frame in the early stage, but the sun visor can be fixed regardless of rotation of the face frame when a predetermined limit is reached.

(58) Embodiments of the present invention were described above and it will be apparent to those skilled in the art that the present invention may be modified in various ways without departing from the scope of the present invention, other than the embodiments described above. Therefore, the embodiments should be construed as examples, not specifying the present invention, and the present invention is not limited thereto and may be modified within the scope of claims or a range equivalent to the scope.
