8 and 9 are views for explaining a process of detaching the shield from the chin protector in the front cover for a helmet according to an embodiment of the present invention.

Referring to FIG. 8( a ), the shield part may be moved based on the chin protection part.

Among the separation distances between the front end of the shield and the front end of the chin protection, the position of the shield when the distance between the front end of the shield and the front end of the chin protection is the closest may be referred to as the closed position of the shield.

Conversely, among the separation distances between the front end of the shield and the front end of the chin protector, the position of the shield when the distance between the front end of the shield and the front end of the chin protector is the longest may be referred to as an open position of the shield.

When the shield part is in the closed position, the coupling body parts 2131a and 2131b may be hidden from the outside by the shield part 2300 .

When the shield part 2300 is in the closed position, the wearer may not be able to operate the first coupling body part 2131a.

The shield part 2300 may be rotated based on the chin protection seat part 2120 when the shield part 2300 is connected to the chin protection seat part 2120 .

When the shield part 2300 is located in the open position, the coupling part may be connected to the chin protection seating part 2120 so that a part of the coupling part is hidden by the shield part 2300 and the remaining part is exposed to the outside.

Referring to FIG. 8( b ), when the shield part 2300 is moved from the closed position to the open position, at any position between the closed position and the open position of the shield part 2300 , the first coupling The body portion 2131a may be exposed to the outside.

However, referring to FIG. 8(c) , when the first coupling body part 2131a is most exposed to the outside, the shield part 2300 may be in the open position.

Therefore, in order for the wearer to apply an external force to the first coupling body part 2131a, it may be preferable to position the shield part 2300 to an open position.

Fig. 9 (a) is a view showing when the engaging part is in the locking position, and Fig. 9 (b) is a view showing when the engaging part is in the unlocking position.

When the coupling part is in the locked position, the coupling part may restrict the movement of the position of the shield part so that the shield connected to the chin protection seating part is not separated from the chin protection seating part.

When the coupling part 2130 is in the release position, the coupling part may not limit the movement of the position of the shield part so that the shield part connected to the chin protection seating part can be separated from the chin protection seating part.

4, 7 (a) and 9 (a), when the coupling part 2130 is in the locked position, the second coupling body part 2131b is uniform with the first movement limiting part 2150. side can be achieved.

That is, when the coupling portion 2130 is in the locked position, a portion of the second coupling body portion 2131b may be located above the first guide portion 2121 .

For this reason, when the coupling part 2130 is in the locked position, when the first protrusion 2320 is positioned on the first guide part 2121 , the 1-2 protrusion 2322 is the second coupling part Since it is caught by the main body 2131b and the first movement limiting part 2150 , the first protrusion 2320 may not be separated from the first guide part 2121 .

Also, when the coupling part 2130 is in the locked position, the first protrusion 2320 may not be inserted into the first guide part 2121 .

When no external force is applied to the first coupling body portion 2131a, the coupling portion 2130 may maintain a locked position.

When the coupling part 2130 is in the locked position, a portion of the coupling part 2130 is disposed on the upper side of the first guide part 2121 , and the coupling part 2130 is the first guide part 2121 . It is possible to prevent the first protruding part 2320 inserted into the first guide part 2121 from being separated from the first guide part 2121 .

In order to connect the shield part 2300 to the chin protection seat part 2120 , the first protrusion part 2320 may have to be inserted into the first guide part 2121 .

Alternatively, in order to separate the shield part 2300 from the chin protection seat part 2120 , the first protrusion part 2320 may need to be separated from the first guide part 2121 .

To this end, referring to FIGS. 4, 7 (a) and 9 (b), in order to move the coupling part 2130 from the locked position to the unlocked position, the wearer is attached to the first coupling body part 2131a. External force can be applied.

When an external force is applied to the first coupling body part 2131a, the first coupling body part 2131a and the second coupling body part 2131b may be rotated based on the coupling shaft part 2132.

Due to this, the jaw elastic part 2140 can be contracted to store elastic energy.

When the coupling part 2130 is in the release position, the second coupling body part 2131b may not form a uniform side surface with the first movement limiting part 2150 .

When the coupling part 2130 is in the locked position, a portion of the second coupling body part 2131b may not be positioned above the first guide part 2121 .

For this reason, when the coupling part 2130 is in the released position, when the first protrusion 2320 is positioned on the first guide part 2121 , the 1-2 protrusion 2322 is the second coupling part Since it is not caught by the main body 2131b, the first protrusion 2320 may not be separated from the first guide 2121 .

Also, when the coupling part 2130 is in the release position, the first protrusion 2320 may be inserted into the first guide part 2121 .

When the external force is removed from the first coupling body part 2131a, the coupling part 2130 may be moved to a locked position by the jaw elastic part 2140.

When the coupling part 2130 is in the release position, all parts of the coupling part 2130 are not disposed on the upper side of the first guide part 2121 , so that the first inserted into the first guide part 2121 . The protrusion 2320 may be separated from the first guide part 2121 .

Hereinafter, the process of attaching and detaching the shield part will be described in detail.

When the shield part is in the open position, the second protrusion part 2330 may be separated from the upper side of the second guide part 2122 .

When the shield part is in the protective position, the second protrusion 2330 may be positioned at a position corresponding to the second movement limiting part 2160 .

In order to separate the shield part from the chin protection seating part 2120, the wearer may position the shield part to an open position.

The 1-2 protrusion part 2322 may be positioned at a position corresponding to the second coupling body part 2131b.

In addition, the 2-2 protrusion 2332 may be located in the second guide part 2122 in which the second movement limiting part 2160 is not disposed among the second guide parts 2122 .

Also, the 4-2th protrusion 2352 may be located in the third guide part 2123 in which the third movement limiting part 2170 is not disposed among the third guide parts 2123 .

Therefore, when the shield part is in the open position, the 1-2 protrusion part 2322 is caught by the second coupling body part 2131b, and the shield part may not be separated from the chin protection part 2100 .

Conversely, when the shield part is not in the open position, the 1-2 protrusion 2322 is caught by the second coupling body part 2131b and the first movement limiting part 2150, so that the shield part is the chin It may not be able to separate from the protection part.

Also, when the shield part is not in the open position, the 2-2 protrusion part 2332 is caught by the second movement limiting part 2160 , so that the shield part may not be separated from the chin protection part.

In addition, when the shield part is not in the open position, the 4-2 protrusion 2352 is caught by the third movement limiting part 2170 , so that the shield part may not be separated from the chin protection part.

By applying an external force to the first coupling body portion 2131a by the wearer, the coupling portion 2130 may be moved from the locked position to the unlocked position.

Thereafter, while the 1-2 protrusion 2322 is separated from the first guide part 2121 , the shield part may be separated from the chin protection part 2100 .

The connection process of the chin protection part of the shield part may be performed in reverse of the above-described separation process, and a detailed description thereof may be omitted.

Hereinafter, a process in which the helmet front cover is detachably attached to the helmet shell will be described in detail.

When the helmet front cover 2000 is in the lowered position, the chin protection protrusion 2190 may not be inserted into the shell guide parts 1221 and 1222 .

11 ( b ) and 12 ( b ), when the helmet front cover 2000 is in an intermediate position, the chin protection protrusion 2190 may be inserted into the first shell guide part 1231 .

Here, the chin protection protrusion 2190 may be in contact with the shell protrusion 1233 .

When the front cover 2000 for a helmet is in an intermediate position, the position of the front cover 2000 for a helmet may not be fixed.

For example, a user may apply an external force to the front cover 2000 for a helmet to move the front cover 2000 for a helmet from a lowered position to an intermediate position.

Here, if the user removes the external force applied to the front cover 2000 for the helmet, the front cover 2000 for the helmet, which is an intermediate position, may be moved to the lowered position.

11(c) and 12(c), if the front cover 2000 for a helmet, which is an intermediate position, is continuously moved upward, the chin protection protrusion 2190 slides the shell protrusion 1233. It may be inserted into the second shell guide part 1222 too much.

That is, when the helmet front cover 2000 is in the raised position, the chin protection protrusion 2190 may be inserted into the second shell guide portion 1222 .

When the helmet front cover 2000 is in the raised position, since the shell protrusion 1233 restricts the movement of the chin protection protrusion 2190, the position of the helmet front cover 2000 may be fixed. (in the fixed state)

However, if an external force greater than a predetermined standard is applied to lower the helmet front cover 2000, which is an elevated position, the chin protection protrusion 2190 slides the shell protrusion 1233 and moves to the first shell guide part 1231. it might be

When the helmet front cover 2000 is in the raised position, a portion of the shell lock body 1310 may be exposed to the outside.

On the other hand, when the front cover 2000 for the helmet is in the lowered position and/or the intermediate position, the shell lock body 1310 is not exposed to the outside and may be hidden by the front cover 2000 for the helmet.

Therefore, in order to separate the helmet front cover 2000 from the helmet shell, the wearer may perform a separation operation after moving the helmet front cover 2000 to an elevated position.
