In addition, the slide member 1 may include a slide control unit 177. For example, referring to FIGS. 5A and 5B, when the shield 200 is mounted on the shield fastening device 100 for the helmet, the lower portion of the slide member 1 that is exposed to the shield 200 is not hidden. It may be a controller 177. For example, by sliding the slide member 1 as shown in FIG. 5A by sliding the slide control unit 177 in the state where the shield 200 is mounted on the shield fastening device 100 for helmet as shown in FIG. 5B, The shield 200 can be separated from the shield fastening device 100 for the helmet. As such, the slide controller 177 may be provided for sliding control of the slide member 1 for detachment of the shield 200.

The member fastening unit 53 is fastened to the base member 3 by passing through the member fastening unit mounting hole 173, and the slide member 1 mounted between the member fastening unit 53 and the base member 3 is The member fastening unit mounting hole 173 may slide along a path formed.

In addition, the shield coupling device 100 for the helmet includes a base member (3).

2 to 7, the slide member 1 is slidably disposed in the base member 3 in the direction in which the elastic member 51 is compressed, and an upper groove (not shown) surrounding the upper portion of the coupling protrusion 210. 311) is formed. As described above, the base member 3 is coupled to the elastic member 51.

In addition, the base member 3 includes a rotation guide part 31 for guiding the rotation of the shield 200 in stages. 2, 3, and 5A to 7B, the rotation guide part 31 includes a rotation slot 313 and a buffer slot 315.

Referring to FIG. 4, a rotation slot fastening protrusion 230 may protrude from an inner surface of the shield 200 rotatably mounted to the shield coupling device 100 for a helmet. 5A to 6B, a plurality of partition protrusions 313a are formed on an inner surface of the rotation slot 313 of the base member 3 so that the rotation slot fastening protrusion 230 is fastened to one of the partitioned regions. . In other words, the slot area formed by the rotation slot 313 is partitioned through the plurality of partition protrusions 313a, and each of the partitioned areas may be formed in a shape in which the rotation slot fastening protrusion 230 may be fastened.

In addition, the buffer slot 315 is formed to be spaced apart from the inner surface of the rotation slot 313 in which the plurality of partition protrusions 313a are formed by a predetermined interval. Here, the predetermined interval is between the buffer slot 315 and the rotation slot 313 so that the rotation slot fastening protrusion 230 can be moved while pushing each of the plurality of partition projections (313a) when the shield 200 is rotated. The buffer member 317 may be spaced to have a thickness that can be elastically deformed.

For example, in order to rotate down as shown in FIGS. 5C and 6B while the shield 200 is rotated upward as shown in FIGS. 5B and 6A, Rotation slot fastening protrusion 230 of 200 should be able to move across the partition projection (313a). That is, the buffer member 317 between the buffer slot 315 and the rotation slot 313 is the rotation slot fastening protrusion 230 of the rotation slot 313 when the user applies a force to rotate the shield 200 The partition protrusion 313a formed on the inner surface is preferably provided to a thickness that can be elastically deformed to the outside to the extent that it can be moved to the adjacent partitioned region.

In the related art, a separate complicated shock absorber has to be attached in order to perform the sequential rotation of the shield 200 only when the user applies an appropriate force, thereby causing the overall complexity of the apparatus. On the contrary, the shield coupling device 100 for a helmet is a rotary slot 313 having a buffer slot 315 and a partition protrusion 313a on the base member 3 itself, without attaching a separate complicated shock absorber. Since stepwise rotation of the shield 200 can be easily implemented by only forming a), the manufacturability, robustness, and operational stability of the device are greatly improved.

The elastic piece 33 is shot when sliding in the direction in which the elastic member 51 of the slide member 1 is compressed and may be fastened to the receiving groove 13 (see FIGS. 5A and 7B). In addition, the elastic piece 33 may be released from the receiving groove 13 when the external force is applied from the front (see FIGS. 5B and 7A). 5A and 5B, the external force from the front may mean a force acting by pressing the elastic piece 33 of the flange 211 of the coupling protrusion 210.

For example, the elastic piece 33 elastically presses the back surface of the slide member 1 as shown in FIG. 7A, and the slide member 1 compresses the elastic member 51 as shown in FIG. 7B. When sliding in the direction of the predetermined distance to the receiving groove 13 side while the end is engaged with the receiving groove 13 is fastened. On the contrary, as shown in FIG. 5A, the elastic piece 33 fastened to the receiving groove 13 is again received by the pressing pressure of the flange 211 provided in the engaging protrusion 210 of the shield 200. ), The slide member 1 slides in the direction in which the elastic member 51 is stretched (elastic recovery) as shown in FIG. 5B.

In other words, when the elastic piece 33 is fastened to the receiving groove 13, the coupling protrusion 210 of the shield 200 may be mounted between the lower groove 11 and the upper groove 311. At this time, the elastic piece 33 is separated from the receiving groove 13 by pressing the elastic piece 33 of the flange 211 of the coupling protrusion 210 at the same time. When the elastic piece 33 is separated in this way, the slide member 1 is slid in the direction in which the compressed elastic member 51 is elongated again, and the elastic piece 33 is separated according to the movement of the slide member 1. While the flange 211 is accommodated in the receiving groove 13, the shield 200 is mounted on the shield coupling device 100 for the helmet.

On the contrary, when the slide member 1 is moved (moving from the state of FIG. 5B to the state of FIG. 5A) in the compression direction of the elastic member 51, the flange 211 accommodated in the accommodation groove 13 is accommodated. The mounting of the shield 200 to the shield coupling device 100 for the helmet may be possible while leaving the groove 13. For reference, the user may detach the shield 200 by moving the slide member 1 in the direction in which the elastic member 51 is compressed through the salping slide control unit 177.

In this way, the slide member 1, the receiving groove 13, the elastic member 51, and the elastic piece 33 are organically combined, so that the selective reception of the flange 211 with respect to the receiving groove 13 is simple. It can be easily made only by operation, the detachment of the shield 200 to the shield coupling device 100 for the helmet can be made smoothly, and once the flange 211 is received in the receiving groove 13, the shield 200 ) Can maintain a stable mounting state, it is possible to remove the smooth and secure mounting stability.

In addition, a flange guide groove 311a may be formed in the upper groove 311 to accommodate the flange 211 of the coupling protrusion 210 to prevent the coupling protrusion 210 from being separated when the shield 200 is rotated. That is, as shown in FIG. 6B to prevent the flange 211 from continually leaving the outside even when the shield 200 is rotated in the state where the flange 211 is accommodated in the receiving groove 13 as shown in FIG. 6A. Likewise, a flange guide groove 311a may be formed in the upper groove 311. For example, as shown in FIGS. 6A and 6B, the flange guide groove 311a may be arced along the rear surface of the upper groove 311 so as to receive the flange 211 continuously during the rotation of the shield 200. It can be formed as.

3, 7A, and 7B, a slide slot 373 may be formed in the base member 3 to guide the sliding path of the slide member 1. In response to the slide slot 373 of the base member 3, the slide member 1 may include a slot fastening member 175 slidably fastened to the slide slot 373. Through the slide slot 373 and the slot fastening member 175, the sliding of the slide member 1 with respect to the base member 3 can be made more stable.

Meanwhile, referring to FIGS. 1A and 1B, the helmet 1000 according to an exemplary embodiment of the present disclosure may further include a jaw protector 410 mounted to the helmet body 400. The base member 3 of the shield coupling device 100 for the helmet 100 may be fastened to the jaw protector 410, and the base member 3 may be fastened to the helmet body 400 while being fastened to the jaw protector 410. It can be rotatably mounted. 1A and 1B, the jaw protector may be rotated up and down with respect to the helmet body 400 through the base member 3.

1A to 3, a helmet body fastener 35 may be formed on the base member 3 to be rotatably mounted to the helmet body 400. As a specific example, by fastening the helmet body fastener 35 to the pivot shaft mechanism 411, the base member 3 may be rotatably mounted to the helmet body 400.

In this case, the center of the helmet body fastener 35 may coincide with the rotation center of the coupling protrusion 210 of the shield 200 which is surrounded by the lower groove 11 and the upper groove 311. That is, the rotation center of the shield coupling device 100 for the helmet body 400 with respect to the helmet body 400 and the rotation center of the shield 200 with respect to the shield coupling device 100 for the helmet may coincide. Coaxial rotation may be implemented in which both the rotation of the shield 200 and the rotation of the jaw guard 410 are performed about an axis.

The jaw protector 410 and the shield coupling device 100 for the helmet may be manufactured in one piece, but as described above, the jaw protector 410 and the shield coupling device 100 may be manufactured in a separable type. As a specific example, as shown in the figure, the jaw guard 410 and the shield coupling device 100 for the helmet in such a manner as to fasten the fastening unit (not shown in the drawing) to the jaw guard fastener 55 formed on the base member 3. ) May be fastened.

For example, when the base member 3 is integrally injected with the jaw guard 410, an appropriate pressure may be applied in the normal direction of the base member 3 in order for the base member 3 to be injected in a desired shape. High pressure was required. On the contrary, when the shield coupling device 100 for the helmet is provided as a detachable type, the shield coupling device 100 for the helmet may be manufactured separately from the jaw guard 410, and thus the high pressure described above may be produced in the injection of the jaw guard 410. Since it is not necessary, easier fabrication can be made.

In addition, when the base member 3 is integrated with the jaw protector 410, there is a hassle of masking the base member 3 when the jaw protector 410 is coated. On the contrary, when the shield coupling device 100 for the helmet is provided as a detachable type, since the shield coupling device 100 for the helmet is not required to be masked when the jaw protector 410 is painted, the fabrication of the helmet can be made more easily. have.

In addition, since the shield coupling device 100 for the helmet may have a problem that can be easily broken due to frequent rotational drive, by providing a separate shield coupling device 100 for the helmet, unlike the jaw guard 410 is required It can be applied to a material different from the jaw protector 410 to suit the strength can be prevented the occurrence of the above-described problems. In addition, if the shield shield coupling device 100 for the detachable type, it is easy to replace and maintain, it is possible to ensure higher usability.

6A to 7B, a limiting protrusion 57 may be provided on the rear surface of the base member 3.

8A, the helmet body 400 is formed along the circumference of the helmet body fastener 35, and the rotation limit slot 431 into which the limiting protrusion 57 is inserted so as to limit the rotation range of the base member 3. And a limiting buffer buffer slot 433 spaced apart from the inner surface of the rotation limiting slot 431.

For example, referring to FIGS. 8B and 8C, the restricting protrusion 57 may be rotated only between the other side of the rotation limit slot 431 shown in FIG. 8B and one side of the rotation limit slot 431 shown in FIG. 8C. Through this fastening relationship between the projection 57 and the rotation restriction slot 431, the rotation range of the base member 3 can be limited.

By limiting the rotation range of the base member 3 through the restricting protrusion 57 and the rotation limit slot 431, the jaw protector is rotatably mounted to the helmet body 400 through the shield coupling device 100 for the helmet. It is possible to prevent the 410 from being excessively rotated up more than the state shown in FIG. 8C.

8B, the limiting protrusion 57 may be inserted into the limiting rotation slot 431 to press the inner surface of the limiting slot 431 toward the limiting buffer buffer slot 433. Here, in order for the limiting protrusion 57 to be inserted into the limiting rotation slot 431 to press the inner surface of the limiting rotation slot 431 toward the limiting protrusion buffer slot 433, the limiting projection 57 is formed of the base member 3. Rather than protruding from the back to the position exactly engaged with the rotation restriction slot 431, it is preferable to project slightly biased toward the restriction protrusion buffer slot 433 than the rotation restriction slot 431.

When a user applies a predetermined force to rotate the shield 200, the rotation slot fastening protrusion 230 pushes the partition protrusion 313a to the outside where the buffer slot 315 is formed and moves to a neighboring partitioned area. It can be moved, and thus the step of rotating the shield 200 is made. At this time, the buffer member 317 is preferably provided in accordance with the thickness, material, etc. in consideration of a predetermined force applied by the user to rotate the shield (200).

In addition, when the shield 200 is mounted, the flange 211 accommodated in the receiving groove 13 as shown in FIG. 6A is removed from the receiving groove 13 as shown in FIG. 6B when the shield 200 is rotated. The deviation is continuously prevented by the flange guide groove 311a while moving along the arc-shaped flange guide groove 311a formed on the rear surface of the upper groove 311.

When the stepwise rotation of the shield 200 is repeated, as shown in FIGS. 5C and 6B, the shield 200 is completely rotated downward, which is illustrated in FIG. 1A. It may be said that the front opening of the main body 400 is completely covered.

On the contrary, when the user applies a predetermined force to lift the shield 200 upward in the state shown in FIGS. 5C and 6B so that the front opening of the helmet body 400 covered by the shield 200 is opened again, the rotation slot is fastened. The protrusion 230 pushes the partition protrusion 313a outward and the shield 200 may be rotated upwards stepwise, and may return to the state shown in FIGS. 5B and 6A.

In this state, when the slide control unit 177 exposed to the lower side of the shield 200 is pushed in the direction in which the elastic member 51 is compressed, as shown in FIG. 5B, it is accommodated in the receiving groove 13. As the flange 211 is exposed to the outside again, the shield 200 can be detached.
