1 to 4, the helmet according to the present embodiment includes a helmet body 100 having an opening 150 opened at the front, both ends of which are coupled to the helmet body 100, A shield supporting member 300 provided at one side of the opening 150, a shield mounting part 410 fixed to the shield 200, and a coupling shaft 420, A locker 400 including a coupling part 430 rotatably connected to the mounting part 410 and having a second end coupled to or disengaged from the lock supporting member 300 and a locking part 430 coupled to the locking part 300, It is possible to prevent the coupling portion 430 from rotating with respect to the shield attachment portion 410 by a predetermined angle or more with reference to the coupling shaft 420 so that the coupling portion 430 is locked to the lock supporting member 300 And a lock portion 500 for maintaining the state.

The helmet body 100 protects the wearer's head. Here, the helmet body 100 is formed of a material capable of absorbing the impact, and an opening 150 opened to secure the front watch of the wearer is formed at the front.

The shield 200 serves to block wind, dust, and the like. The shield 200 is coupled at both ends to the helmet body 100 to open and close the opening 150 of the helmet body 100. 1 and 2) provided on both sides of the opening 150 of the helmet body 100 so that the helmet body 100 is rotated in the vertical direction, It is possible to open and close the opening portion 150 of the main body.

The locking support member 300 serves to fix the shield 200 together with the locker 400 while closing the opening 150 of the helmet body 100 (see FIG. 2). Here, the lock supporting member 300 may be provided at one side of the opening 150, for example, at the lower center of the opening 150. At this time, the locking support member 300 has a structure in which the locking protrusion 435 of the locker 400, which will be described later, can be caught by the locking support member 300 for fastening the shield 200 through the locker 400 (See Fig. 5A). In addition, the lock supporting member 300 has a structure that can be easily engaged with and disengaged from the engagement step 435 when the shield 200 is fastened and released.

The locker 400 serves to fix the shield 200 by being hooked on the lock supporting member 300 and includes a shield mounting portion 410 and a coupling portion 430 (see FIGS. 3 to 4) .

Here, the shield mounting portion 410 is fixed to one end (lower end) of the shield 200 to prevent the locker 400 from being arbitrarily separated from the shield 200. The shield mounting portion 410 may further include a mounting plate 413 (see FIG. 4) facing the rear surface of the shield 200 for stable connection with the shield 200. The mounting plate 413 may be protruded from the shield mounting portion 410 or may be formed to be concave. One end (lower end) of the shield 200 is sandwiched between a space formed between the mounting plate 413 and the back surface of the shield mounting portion 410 so that the rocker 400 is finally separated from the shield 200 arbitrarily . The mounting plate 413 may be formed with a perforated hole into which the coupling shaft 420 is inserted so that the mounting plate 413 can be rotatably connected to the coupling portion 430 through the coupling shaft 420.

Meanwhile, the coupling part 430 serves to fasten or unlock the locker 400 to the lock supporting member 300. 5A), the fastening portion 430 is fastened to the lock supporting member 300, and the shielding portion 430 is fastened to the lock supporting member 300. Thus, when the shield 200 is in the position to close the open portion 150 (200) keeps the open portion (150) closed. 5B), the fastening portion 430 is released from the locking support member 300 so that the shield 200 is released from the opening portion (not shown) 150 can be opened. Specifically, one end (upper end) of the coupling portion 430 is connected to the shield attachment portion 410 through the coupling shaft 420 so as to be rotatable, and the other end (lower end) thereof is engaged or disengaged with the lock support member 300.

More specifically, at the other end of the coupling part 430, a locking protrusion 435 protruding inward of the shield 200 may be formed so as to be caught by the lock supporting member 300. Here, the locking protrusion 435 may be formed as an annular member protruding inward from the shield 200 in the locking part 430, and the locking part 430 may be fastened to the locking supporting member 300 Or released. At this time, the lock supporting member 300 fastened to the latching jaw 435 protrudes downward in a convex manner so as to facilitate engagement or disengagement with the latching jaw 435, and the rear portion of the protruded portion is recessed upward Sectional shape. Needless to say, the locking protrusion 435 and the locking support member 300 may be formed in any shape other than the above-described shape as long as they can be fastened or released.

The fastening portion 430 may further include a first grip portion 437 protruding outwardly of the shield 200. The first grip portion 437 protrudes from the grip portion 430 in the form of a handle in the outer direction of the shield 200. When the wearer pushes the first grip portion 437, And can be released from the lock supporting member 300. At this time, the first handle 437 may be provided in a direction opposite to the engaging protrusion 435 with respect to the engaging shaft 420. 5A and 5B) when the fastening portion 430 is fastened to the lock supporting member 300, the fastening tab 435 moves downward So that the coupling part 430 and the lock supporting member 300 can be released so that the shield 200 can be pivoted to open the opening part 150. [

For this purpose, the shield mounting part 410, the mounting plate 413, A perforated hole may be formed at one end of the fastening portion 430 so that the fastening portion 420 is inserted into the hole. That is, the holes formed in the shield mounting portion 410 and the mounting plate 413 are aligned with the holes formed at one end of the coupling portion 430 to insert the coupling shaft 420, (410) may be pivotably connected. The coupling shaft 420 may be formed in a rod shape having a predetermined length so as to fasten the coupling part 430 and the shield mounting part 410. However, All known techniques for fastening the shield mounting portion 410 can be used.

3 to 4, the locker 400 includes an elastic member 440 that provides elasticity between one end of the coupling portion 430 fastened by the coupling shaft 420 and the shield mounting portion 410, ). The elastic member 440 is fixed to the locking support member 300 so as to maintain the fastening of the locking part 430 with respect to the locking supporting member 300 in a state where the locking part 430 is fastened to the locking supporting member 300 Provides elasticity. That is, the elastic member 440 elastically supports the locking protrusion 435 of the locking part 430 in the upward direction to maintain the engagement of the locking protrusion 435 of the locking part 300 and the locking part 430 will be. The elastic member 440 elastically urges the locking protrusion 435 of the locking part 430 upward when the locking protrusion 435 of the locking part 430 is released from the locking supporting member 300 And returns to its original position. The type of the elastic member 440 is not particularly limited, but a torsion spring can be used as shown in the figure. When the elastic member 440 is a torsion spring, the elastic member 440 may be disposed so as to surround the coupling shaft 420. At this time, when the first handle 437 is pushed upward, the engagement protrusion 435 of the coupling part 430 moves downward, and the elastic member 440 is compressed. Thereafter, when the force is removed from the first handle 437, the compressed elastic member 440 returns to its original shape, and the elasticity of the retaining jaw 435 of the fastening portion 430 is restored to its original position .

It is also possible to form or provide an additional coupling member so that the rocker 400 can be more stably coupled to the shield 200. For example, as shown in FIGS. 3 to 4, a guide groove 210 may be formed at the lower end of the shield 200 so that the shield mounting portion 410 can be effectively mounted on the shield 200 . The guide groove 210 is a groove formed at one end (lower end) of the shield 200. The guide groove 210 is a groove formed at one end (lower end) of the shield 200. The shield mounting portion 410 can be easily attached to the shield 200 corresponding to the shapes of the shield mounting portion 410 and the mounting plate 413. [ Can be fitted and mounted. The guide groove 210 may be formed at one end (lower end) of the shield 200 in various shapes depending on the shapes of the shield mounting portion 410 and the mounting plate 413. In addition to the guide groove 210, A screw connection which can be fastened to the base 410 can also be used. At this time, the first screw groove 417 may be formed on the rear surface of the shield mounting portion 410, and the second screw groove 220 may be formed on the shield 200 corresponding to the first screw groove 417 The shield mounting portion 410 and the shield 200 can be engaged by screwing the screw 419 through the first screw groove 417 and the second screw groove 220.

5A, when the locker 400 and the lock supporting member 300 are fastened together, the elasticity of the elastic member 440 acts counterclockwise on the fastening portion 430, The locking protrusion 435 of the locking member 300 is caught by the locking support member 300. Therefore, it is possible to prevent the shield 200 from rotating and to prevent the opening portion 150 of the helmet body 100 from being opened.

5B, when the first handle 437 of the fastening part 430 is pushed clockwise, the fastening protrusion 435 of the fastening part 430 is separated from the lock supporting member 300. [ At this time, the shield 200 is rotated, so that the opening 150 of the helmet body 100 can be opened.

However, when the wearer unintentionally touches the fastening portion 430 (first grip portion 437), there is a fear that the first grip portion 437 is pushed clockwise and the shield 200 is opened . However, the helmet according to the embodiment of the present invention includes the locking part 500, and thus it is possible to completely prevent the shield 200 from being arbitrarily opened regardless of the intention of the wearer.

7A and 7B, the lock portion 500 is configured such that the coupling portion 430 is coupled to the shield mounting portion 410 in a state where the coupling portion 430 is coupled to the lock supporting member 300, The locking member 430 is prevented from rotating more than a predetermined angle with respect to the locking member 420 to maintain the locked state of the locking member 430 in the locking member 300. [ That is, it is possible to prevent the coupling portion 430 from rotating more than a predetermined angle in a state where the engagement protrusion 435 of the coupling portion 430 is fastened to the lock supporting member 300, .

6A and 7A, the locking part 500 is fastened to the fastening part 430 such that it can slide and move from the fastening part 430 to the first position A and the second position B, Lt; / RTI > 6A and 6B), the fastening portion 430 is rotated with respect to the shield mounting portion 410 by a predetermined angle or more relative to the fastening shaft 420 (See Figs. 7A to 7B), the engaging portion 430 is positioned at a predetermined angle with respect to the engaging shaft 420 with respect to the shield attaching portion 410. When the engaging portion 420 is positioned at the second position B Or more. 6A and 6B), when the locking part 500 is positioned at the first position A (refer to FIGS. 6A to 6B), the locking part 430 is fixed to the shield mounting part 410 at a predetermined angle So that the locking protrusion 435 of the locking part 430 is released from the locking part 500. [ 7A and FIG. 7B), when the locking part 500 is disposed at the second position B (refer to FIGS. 7A to 7B), the locking part 430 is locked to the shield mounting part 410 at a predetermined angle So that the locking protrusion 435 of the locking part 430 is prevented from being released from the locked state of the locking part 500. [

More specifically, a depressed portion 415 is formed on one surface (lower surface) of the shield mounting portion 410 facing the coupling portion 430, and the locking portion 500 is formed in the locking portion main body 510, (Bottom surface) of the shield mounting portion 410 so as to correspond to the depression 415 from one end of the base 510. 6A and 6B), when the engaging portion 430 is rotated with respect to the engaging shaft 420 with respect to the shield attaching portion 410 (refer to Figs. 6A to 6B), when the engaging portion 430 is in the first position A , The protrusion 520 is inserted into the depression 415. 7A and 7B), when the fastening portion 430 is rotated with respect to the shield mounting portion 410 with respect to the fastening shaft 420 , The protrusion 520 contacts one surface (lower surface) of the shield mounting portion 410. 6A and 6B), the protrusions 520 and the depressions 415 are aligned so that the protrusions 520 are spaced apart from the depressions 415 (see FIG. 6A) The coupling portion 430 can be rotated at a predetermined angle or more with respect to the coupling portion 420 with respect to the shield attachment portion 410. [ Therefore, the engaging step 435 of the fastening portion 430 can be released from the lock supporting member 300. [ 7A and 7B), the projection 520 and the depression 415 are displaced and the projection 520 is depressed by the depression 415, (Lower surface) of the shield mounting portion 410 without being inserted into the shield mounting portion 410. Thus, the coupling portion 430 can not be rotated more than a predetermined angle with respect to the coupling shaft 420 with respect to the shield mounting portion 410. [ Therefore, the locking protrusion 435 of the locking part 430 is prevented from being released from the locking supporting member 300. [

On the other hand, the lock portion 500 further includes the second handle portion 530, so that it can be easily moved to the first position A and the second position B. Here, the second handle 530 protrudes outward from the fastening portion 430 from the other end of the lock body 510 (the opposite end of the one end protruding from the protrusion 520). That is, the second handle 530 protrudes to the outside of the fastening part 430 and can be easily operated by the wearer. Specifically, when the wearer pushes the second handle 530, the lock portion 500 moves from the first position A to the second position B, or moves from the second position B to the first position A ). For example, if the second handle 530 is pushed and the lock part 500 is moved from the first position A to the second position B, the fastening part 430 contacts the shield mounting part 410 The locking pawl 435 of the coupling portion 430 is not released from the locking support member 300 (see Figs. 7A to 7B). On the other hand, when the second grip portion 530 is pushed and the lock portion 500 is moved from the second position B to the first position A, The locking protrusion 435 of the locking part 430 can be released from the locking part 500 (see FIGS. 6A to 6B).

The locking portion 500 may be coupled to any position of the locking portion 430 but may be coupled to the first locking portion 437 of the locking portion 430, have. Specifically, the first handle 437 has an extension portion 439 extending vertically (downward) to the distal end, a first through-hole 533 is formed in the extension portion 439, Hole 510 penetrates through the first through-hole 533. The second handle portion 530 extending from the lock portion body 510 may protrude outward of the fastening portion 430 and the extended portion 439 of the first handle portion 437. [ A second through hole 535 is formed in the first handle 437 in the vertical direction, and the protrusion 520 penetrates through the first handle 437. Therefore, the protrusion 520 can protrude from the first handle portion 437 toward the shield mount portion 410. At this time, the lock body 510 and the protrusion 520 are separately formed, and the lock protrusion 511 provided at the end of the protrusion 520 is coupled to the lock body 510 by the clip fastening method. At the same time, 520 may be inserted into the fastening holes 513 formed in the lock body 510. [ As such, the lock body 510 and the protrusions 520 may be coupled in a clip-fastening manner, but are not necessarily limited thereto, and may be combined in any known manner. Also, the lock portion main body 510 and the protrusion 520 may be integrally formed.

The lock portion 500 is guided by the first through hole 533 and the protrusion 520 is guided by the second through hole 535 so that the lock portion 500 is in the first position and the second position Position. 3, the length of the first through hole 533 in the first direction (?, Lateral direction) is equal to the length of the first through hole 533 passing through the first through hole 533, And the length of the first through hole 533 in the second direction (?, Vertical direction) is larger than the length of the first through hole 533 Corresponds to the length in two directions (?, Lateral direction). Therefore, the lock portion main body 510 is guided by the first through hole 533 and can be moved in the first direction (?, Left-right direction), but not in the second direction? (Vertical direction). The length of the second through hole 535 in the first direction (?, Left-right direction) is greater than the length of the protrusion 520 passing through the second through-hole 535 in the first direction? And the length of the second through hole 535 in the third direction (?, Forward and backward direction) corresponds to the length of the protruding portion 520 through which the second through hole 535 penetrates in the third direction? . Therefore, the protrusion 520 is guided by the second through-hole 535 and can be moved in the first direction (?, Left-right direction), but not in the third direction? (Back-and-forth direction). The lock portion 500 including the lock portion main body 510 and the protrusion 520 is guided by the first through hole 533 and the second through hole 535 and is guided in the first direction? And does not move in the second direction (?, Up-down direction) or the third direction (?, Back-and-forth direction). That is, the lock portion 500 moves from the first position A to the second position B while sliding in only one direction (the first direction?), Or moves from the second position B to the first position A A).

8A to 8B, a second handle 530 protruding from the lock body 510 is provided at one end of the first through hole 533, and the second handle 530, The cross-sectional area of the first through-hole 533 is larger than that of the first through- Therefore, the second handle 530 is hooked to one end of the first through hole 533. A locking protrusion 511 protruding from the lock body 510 is formed at the other end of the first through hole 533 and the locking protrusion 511 is caught by the other end of the first through hole 533. [ Since both ends of the first through hole 533 are engaged with the second handle 530 and the locking protrusion 511, the locking portion 500 is stably fixed in the third direction? Can be moved while sliding in only one direction (?, Left and right direction). At this time, the locking protrusion 511 may be a clip portion provided at the end of the protrusion 520 for coupling the lock body 510 and the protrusion 520 (see FIGS. 3 to 4).

In addition, a housing space 537 (see Figs. 4 and 8A to 8B) in which the lock body 510 is disposed may be formed at the fastening portion 430 (behind the first through hole 533) The elastic part 515 may be formed at one end of the main body 510. The elastic portion 515 may be elastically deformed in a direction approaching the lock portion main body 510. For example, the elastic portion 515 may be a plastic elastic body integrally projected with the lock portion main body 510, But any configuration capable of elastic deformation can be employed. The first protrusion 517 protrudes in the direction away from the lock portion main body 510 and protrudes toward the elastic portion 515 in the accommodation space 537 formed in the coupling portion 430 The second protrusion 519 is formed. At this time, the first protrusion 517 protrudes from the center of the lock body 510, and the second protrusion 519 protrudes from the center of the receiving space 537. 8A to 8B, when the lock portion 500 is moved from the first position A to the second position B or from the second position B to the first position A, The first protrusions 517 and the second protrusions 519 can be resiliently deformed in a direction in which the elastic portion 515 approaches the lock body 510 while being in contact with each other. When the lock portion 500 is disposed at the first position A or the second position B, the side surface of the first projection 517 is caught by the side surface of the second projection 519, Can be fixed. That is, when the lock portion 500 is disposed at the first position A or the second position B, the first projection 517 and the second projection 519 are engaged with each other so that the lock portion 500 does not move arbitrarily When the wearer pushes the second handle 530 to move from the first position A to the second position B or from the second position B to the first position A, The first protrusion 517 can be moved beyond the second protrusion 519 by elastic deformation in a direction in which the protrusion 515 approaches the lock body 510. [ As a result, the lock portion 500 is in the first position A or the second position B when the force of the wearer is not applied by the elastic portion 515, the first projection 517, and the second projection 519 And can move from the first position A to the second position B or move from the second position B to the first position A only when the wearer's force acts.
