For this reason, the opening and closing adjustment unit 170 is rotated, the details thereof will be described later with the operation of the second compression spring 176.

Meanwhile, referring to FIG. 3, a fastening hole 178 is formed at a position at which the head part 172 is coupled to the support plate 132, and the assembly 130 includes the support plate 132 therebetween. The head part 172 is disposed at the opposite side of the head part 172 and coupled to the support plate 132 and the head part 172 through the fastening hole 178. It may further include a fastening tool 179 for coupling).

The fastening tool 179 is to serve as a coupling, so that the head portion 172 is not separated from the support plate 132, may include any fastening method known in the art. For example, the fastening tool 179 is provided with a bolt, it can be coupled to the head portion 172 through the fastening hole 178 from the back of the support plate 132.

The body 174 serves as a member to which the first hook 126 is caught when opening and closing the shield 120, and adjusts the opening and closing of the shield 120 step by step to open and close the shield 120 in a specific manner. To keep the level of Here, the body portion 174, like the first locking member 164, may be provided to be hooked to the first hook 126. In addition, as shown in FIG. 8, the body portion 174 may be formed to protrude upward. Accordingly, the first hook 126 may be caught on the outer surface of the body 174 in correspondence with the first hook 126.

In addition, an uneven structure may be formed on an outer surface of the body portion 174 and one side of the first hook 126 of the shield 120. In this case, the concave-convex structures may be engaged with each other, so that the opening and closing of the shield 120 may be adjusted in stages. Specifically, on one side of the first hook 126, a first concave-convex structure 190 is formed in which the protrusion and the depression are repeated, and on the outer surface of the body portion 174, the first concave-convex structure 190 is fitted. The second uneven structure 192 may be formed to be bitten.

Thus, when the shield 120 is rotated and opened and closed, the shield 120 may be fixed when the protrusion of one uneven structure is inserted into the depression of the other uneven structure. Therefore, the specific opening and closing degree of the shield 120 can be kept fixed.

Here, the first uneven structure 190 and the second uneven structure 192 may be rounded. Therefore, the protrusions and the depressions of the concave-convex structures can be continuously engaged to facilitate the opening and closing of the shield 120.

In addition, the assembly 130 may further include a second compression spring 176 between the inner surface of the body portion 174 and the outer surface of the button fastener 150. At this time, both ends of the second compression spring 176 is supported by the inner surface of the body portion 174 and the outer surface of the button fastener 150 adjacent to the inner surface of the body portion 174.

The second compression spring 176 serves to return the opening and closing adjustment unit 170 to the third position from the fourth position. Here, the third position is a position when the protrusion of any one of the first uneven structure 190 and the second uneven structure 192 is inserted into the recessed portion of the other uneven structure (see FIG. 7A). The fourth position is a position of the body portion 174 when the protrusion of the first uneven structure 190 and the second uneven structure 192 is engaged when the shield 120 is opened and closed, and a force is applied to the body portion 174. (See FIG. 7B). Accordingly, the third position is the position of the body portion 174 when the shield 120 is fixed, and the fourth position is the position of the body portion 174 when the shield 120 is to be rotated while opening and closing the shield 120. do.

Details of the second compression spring 176 will be described later with reference to the opening and closing of the shield 120.

In addition, the assembly 130 may further include a limiting member 180 to limit the rotation of the opening and closing adjustment unit 170. Here, the limiting member 180 surrounds the outer surface of the head portion 172, and an opening portion 182 is formed to allow the body portion 174 to pass on one side thereof. Specifically, when the body portion 174 is rotated, one end of both ends of the opening portion 182 is caught by one side of the body portion 174, so that the body portion 174 is in the third and fourth positions and between. Only allow rotation.

Specifically, when the user applies a force to the shield 120 to rotate the shield 120, the protrusion of the first concave-convex structure 190 and the protrusion of the second concave-convex structure 192 is engaged from the shield 120 Pressure is applied to the body portion 174. At this time, as the head portion 172 is rotated, the body portion 174 is rotated from the third position, while one side of the body portion 174 is in contact with one end of the limiting member 180, the body portion is no longer (174) will not be able to turn. Accordingly, the body portion 174 stops at the fourth position, and the distal end of the body portion 174 is positioned on the same line as the first catching member 164 to form the first uneven structure 190 and the second uneven structure 192. To maintain continuity. In addition, the second compression spring 176 is in a compressed state.

On the other hand, when the protrusion of one of the uneven structure is inserted into the depression of the other uneven structure, the spring back (spring back) by the restoring force by the elasticity of the second compression spring 176, the body portion 174 is It can rotate from a 4th position. At this time, while the other side of the body portion 174 is in contact with the other end of the limiting member 180, the body portion 174 is no longer able to rotate. Thus, the body portion 174 stops in the third position, where the distal end of the body portion 174 is spaced apart from the first locking member 164.

In addition, the outer surface of the first catching member 164 may correspond to the first uneven structure 190 to be engaged, extend to maintain the continuity with the second uneven structure 192, and rounding treatment. The third uneven structure 194 may be formed.

Specifically, when the shield 120 is fully open, the first hook 126 is caught by the first catching member 164, and the second hook 128 is caught by the second catching member 165 (FIGS. 1A and 1B). 5a). At this time, the first concave-convex structure 190 formed on the outer surface of the first hook 126 is engaged with the third concave-convex structure 194 of the first locking member 164, so that the opening and closing step of the shield 120 can be adjusted. The range is expanded. Therefore, unlike the present embodiment, from the state in which the shield 120 is completely open, there is an advantage that the step adjustment of the opening and closing of the shield 120 is possible.

Meanwhile, the assembly 130 further includes an auxiliary member disposed to face the opening and closing adjustment part with the button fastener 150 interposed therebetween, and supporting the rotation of the shield by the second hook of the shield. can do.

The auxiliary member 166 serves to guide the movement of the second hook 128 when the shield 120 is rotated and opened. 7A to 7B, the auxiliary member 166 may have one end of the auxiliary member 166 and the second locking member 166 to maintain continuity with the second locking member 165 in the first position. Adjacent ends of 165 may be formed on the same line and abut. In addition, the auxiliary member 166 may extend along the rotation path of the second hook 128 of the shield 120, and the second hook 128 of the shield 120 may be caught to assist the rotation of the shield 120. have.

Specifically, when the shield 120 is rotated, the first hook 126 is rotated while maintaining the state caught by the body portion 174 of the first locking member 164 or the opening and closing adjustment unit 170. At this time, in order for the shield 120 to rotate stably without shaking, it is preferable that there is a member to which the second hook 128 can be caught. Therefore, when the auxiliary member 166 is provided, when the shield 120 rotates, the auxiliary member 166 can be stably rotated while being held by the auxiliary member 166. In this case, as shown in FIGS. 7A to 7B, the auxiliary member 166 is similar to the first locking member 164 and the second locking member 165 facing each other with the button fastener 150 interposed therebetween. It is provided to face the body portion 174 of the opening and closing adjustment unit 170 with the button fastener 150 therebetween.

9A and 9B are plan views illustrating an assembly fixed to a helmet according to another embodiment of the present invention.

On the other hand, there is a risk that the shield 120 of the helmet 100 is separated from the helmet 100 regardless of the user's intention. Specifically, when the shield 120 is fully open, and the first hook 126 is caught by the first catching member 164 and the second hook 128 is caught by the second catching member 165, the button 140 is closed. When pressed, the shield 120 is separated. If the shield 120 is fully opened, an accident or the like occurs and the button 140 is pressed irrespective of the user's intention, and the shield 120 is separated, thereby causing a greater accident. Therefore, in order to prevent such an accident, the first hook 126 or the second hook 128 of the shield 120 is the first locking member 164 or the second locking member 165 irrespective of the user's intention, respectively. It is necessary to prevent it from getting caught.

Thus, as shown in FIG. 9A, when the actuating member 160 is in the first position, the first catching member 164 in this first position is such that the continuity with the body portion 174 is interrupted. A step is formed with the portion 174 and may be disposed outside the button fastener 150 than the body portion 174. In addition, the second locking member 165 in the first position is formed with a step between the auxiliary member 166 so that the continuity with the auxiliary member 166 is disconnected, and the button fastener 150 is larger than the auxiliary member 166. From the outside.

Specifically, during the process of opening the shield 120 in the closed state, the first hook 126 is rotated along the body portion 174. At this time, the first hook 126 passes through the body portion 174 to the first locking member 164, and the first locking member 164 is located outward from the button fastener 150 than the body portion 174. Since it is arranged, the first hook 126 is blocked by the side of the first locking member 164, so that it can no longer proceed. Therefore, the shield 120 is not completely opened, and the first hook 126 does not proceed to the first locking member 164, and thus is not caught by the first locking member 164. Therefore, even if the button 140 is pressed, there is no risk of the shield 120 being separated.

In addition, during the process of opening the shield 120 in the closed state, the second hook 128 rotates along the auxiliary member 166. At this time, the second hook 128 passes through the auxiliary member 166 to the second locking member 165, and the second locking member 165 is located outward from the button fastener 150 than the auxiliary member 166. Since it is arranged, the second hook 128 is blocked by the side of the second locking member 165, so that it can no longer proceed. Therefore, the shield 120 is not completely opened, and the second hook 128 does not proceed to the second locking member 165, and thus is not caught by the second locking member 165. Therefore, even if the button 140 is pressed, the shield 120 is not separated. As a result, there is no risk that the shield 120 may be separated irrespective of the intention of the user, thereby reducing the risk of injury or injury to the user.

On the other hand, if the user wants to remove the shield 120, pressing the button 140, as shown in Figure 9b, the operating member 160 is moved from the first position to the second position first locking member 164 ) And the second locking member 165 is moved into the button fastener 150. Therefore, the first hook 126 or the second hook 128 is no longer blocked on the side of the first locking member 164 or the second locking member 165, respectively. As a result, the user may move the shield 120 to the fully open position and at the same time detach the shield 120 from the helmet 100.

Although the present invention has been described in detail through specific examples, it is intended to describe the present invention in detail, and the present invention is not limited thereto, and should be understood by those skilled in the art within the technical spirit of the present invention. It is obvious that modifications and improvements are possible.
