The objects, particular advantages and novel features of the invention will become more apparent from the following detailed description and preferred embodiments taken in conjunction with the accompanying drawings. In this specification, when assigning the reference numerals to the constituent elements in each figure, it should be noted that the same constituent elements have the same reference numerals as much as possible even if they appear in other figures. Furthermore, terms such as "first" and "second" are used to distinguish one component from another, and the components are not limited by the terms. In the following description of the present invention, detailed descriptions of related known techniques that may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a perspective view of a helmet to which a helmet chinstrap divider according to an embodiment of the present invention is applied, and FIGS. 2 and 3 are plan views showing the operation process of the helmet chinstrap divider according to an embodiment of the present invention.

As shown in FIGS. 1 to 3, the helmet chinstrap divider according to the present embodiment includes a first support 100 connected to a first chinstrap 200 extending from the front side of a helmet 500, and a first support The helmet 500 includes a second support 300 that is rotatably coupled to the body 100 and connected to a second chin strap 400 extending from the rear side of the helmet 500 .

The chinstrap divider for a helmet according to this embodiment has a first chinstrap 200 extending from the front side of the helmet 500 and a second chinstrap 400 extending from the rear side of the helmet 500 that are aligned under the ear of the wearer. It plays the role of gathering people together. Here, the helmet chinstrap divider according to this embodiment includes a first support 100 connected to a first chinstrap 200 and a second support 300 connected to a second chinstrap 400.

Basically, the first support 100 and the second support 300 are rotatably coupled to each other. Here, as shown in FIGS. 2 and 3, the relative position of the first support 100 with respect to the first chin strap 200 can be adjusted using the rocker 160, and the relative position of the first support 100 with respect to the first chin strap 400 can be adjusted. The relative position of 300 can be adjusted with holder 330. That is, it is possible to adjust the length of the first chin strap 200 from the helmet 500 to the first support 100 and the length of the second chin strap 400 from the helmet 500 to the second support 300. In this way, by adjusting the length of the first chin strap 200 or the length of the second chin strap 400, the angle between the first chin strap 200 and the second chin strap 400 changes, so that the first support The angle between the body 100 and the second support 300 also changes. For example, if the length of the first chin strap 200 from the helmet 500 to the first support 100 or the length of the second chin strap 400 from the helmet 500 to the second support 300 becomes shorter (Fig. 3), as the angle between the first chin strap 200 and the second chin strap 400 increases, the angle between the first support 100 and the second support 300 increases (θ1->θ2). . On the other hand, if the length of the first chinstrap 200 from the helmet 500 to the first support 100 or the length of the second chinstrap 400 from the helmet 500 to the second support 300 becomes longer (FIG. 3-> 2), the angle between the first chin strap 200 and the second chin strap 400 decreases, so the angle between the first support 100 and the second support 300 decreases (θ2 -> θ1 ). As described above, even if the angle between the first chin strap 200 and the second chin strap 400 changes depending on the length of the first chin strap 200 or the length of the second chin strap 400, the angle between the first chin strap 200 and the second chin strap 400 changes. By changing the angle between the first support 100 and the second support 300 in accordance with the angle between the chin strap 200 and the second chin strap 400, the angle between the first chin strap 200 and the second chin strap 400 changes. 400 can be prevented from becoming tangled.

Looking more specifically at the first and second supports 100 and 300 with reference to FIGS. 4 and 5, one surface of the first support 100 and one surface of the second support 300 are arranged to face each other, A projecting protrusion 310 is formed on one surface of the second support body 300, and an insertion hole 120 is formed in the first support body 100 to penetrate in the thickness direction so that the protrusion 310 can be inserted. (see Figure 5b). That is, the protrusion 310 of the second support 300 is inserted into the insertion hole 120 of the first support 100, and the first support 100 and the second support 300 are rotatably coupled to each other. Specifically, a hook 315 is formed at the end of the protrusion 310, and when the protrusion 310 passes through the insertion hole 120, the hook 315 of the protrusion 310 hooks onto the end of the insertion hole 120 (see FIG. 5A). In this manner, the hook 315 of the protrusion 310 is hooked onto the insertion hole 120, thereby preventing the first support 100 and the second support 300 from being separated without permission. On the other hand, in the above description, the protrusion 310 is formed in the second support 300, and the insertion hole 120 is formed in the first support 100, but the present invention is not limited to this. A protrusion 310 may be formed on the support 100, and an insertion hole 120 may be formed on the second support 300.

Furthermore, a protection means 320 is inserted into the protrusion 310 . Here, the protrusion 310 protrudes in an annular shape such that a space 317 is formed at the center, and is divided into one or more division sections 319 (see FIG. 5B). Here, the protection means 320 includes a protection body 323 formed in a cylindrical shape so as to be inserted into the space 317 of the protrusion 310, and a protection protrusion radially protruding from the protection body 323 so as to be inserted into the divided section 319. 325. Therefore, the protection body 323 is inserted into the space 317 of the protrusion 310 and the protection protrusion 325 is inserted into the divided section 319, so that the protection means 320 is coupled to the protrusion 310. The protection means 320 coupled to the protrusion 310 is fixed to the protrusion 310 through bonding or screws. The protection means 320 serves to prevent the protrusion 310 (particularly the hook 315) from being damaged and to prevent the hook 315 from being separated from the insertion hole 120 without permission.

Meanwhile, the second support 300 is rotatably coupled to the first support 100 only within a predetermined angular range. Specifically, a depression 110 is formed on one surface of the first support 100 to form a step 115 (see FIG. 4B). In addition, the second support 300 is rotatably coupled to the recessed part 110, and when the second support 300 forms a specific angle with respect to the first support 100, the side surface of the second support 300 is connected to the stepped part 110. Since the second support body 300 is in contact with the second support body 300, it is possible to prevent the second support body 300 from rotating. That is, the rotatable angle of the second support body 300 can be limited by the stepped portion 115 formed on the first support body 100. More specifically, the step portion 115 may include a first step portion 115 a facing one side of the second support 300 and a second step portion 115 b facing the other side of the second support 300 . Here, if the second support body 300 rotates in one direction (see FIG. 2), one side of the second support body 300 comes into contact with the first stepped portion 115a, and the rotation of the second support body 300 is restricted. be done. Moreover, if the second support body 300 rotates in the other direction (see FIG. 3), the other side surface of the second support body 300 comes into contact with the second stepped portion 115b, and the rotation of the second support body 300 is restricted. Ru. On the other hand, the range of the predetermined angle in which the second support body 300 can rotate relative to the first support body 100 can be, for example, 50 degrees to 80 degrees. However, the range of the predetermined angle from 50 degrees to 80 degrees is merely an example, and it goes without saying that the scope of the present invention is not limited thereto.

Furthermore, the first support 100 may include a locker 160 that fixes the first chin strap 200 to the first support 100 (see FIGS. 2 and 3). Specifically, as shown in FIGS. 4a and 4b, a first guide part 130 is formed at one end of the first support 100, and one side of the guide part 130 contacts the first chin strap 200. As shown in FIGS. Further, the locker 160 is disposed on the first guide part 130 and is rotatably coupled to the first support body 100. Thus, as shown in FIG. 6a, when the rocker 160 rotates relative to the first support 100 and the rocker 160 forms a first angle relative to the first support 100, the rocker 160 rotates relative to the first chin strap. 200, the first chin strap 200 is fixed to the first support body 100. On the other hand, as shown in FIG. 6b, when the rocker 160 forms a second angle with respect to the first support 100, the rocker 160 does not press the first chin strap 200, and the first chin strap 200 It is not fixed to the body 100 and moves freely. For example, when the rocker 160 forms 180 degrees with respect to the first support 100 (see FIG. 6a), the rocker 160 can press against the first chinstrap 200, and the rocker 160 can press against the first support 100. When forming a 90 degree angle (see FIG. 6b), the rocker 160 cannot press the first chin strap 200. More specifically, when the rocker 160 is coupled to the first support 100 via the rotation axis 163, the rocker 160 includes two surfaces 165 and 167 having different distances from the rotation axis 163. By rotating, the first chin strap 200 can be pressed or not pressed. That is, the rocker 160 may include a first surface 165 spaced apart from the pivot shaft 163 by a first distance, and a second surface 167 spaced apart from the pivot shaft 163 by a second distance less than the first distance. (See enlarged view in Figures 6a and 6b). Therefore, when the rocker 160 makes a first angle (for example, 180 degrees) with the first support 100 (see the enlarged view of FIG. 6a), the first surface 165 that is relatively remote from the rotation axis 163 is the first guide. The first chin strap 200 is pressed together with the portion 130. On the other hand, when the rocker 160 forms a second angle (for example, 90 degrees) with the first support 100 (see the enlarged view in FIG. 6b), the second surface 167 relatively close to the rotation axis 163 The first chin strap 200 is not pressed together with the guide part 130. Ultimately, the wearer can adjust the length of the first chinstrap 200 by rotating the locker 160 to the first support 100 to fix the first chinstrap 200 to the first support 100 or by making it movable. Adjust. Meanwhile, the first support 100 may form a stopper 170 that stops the rocker 160 when the rocker 160 forms a first angle (for example, 180 degrees) with the first support 100 (see FIG. 6a). good. Here, the stopper 170 is arranged alongside the first guide part 130, and the first chin strap 200 can pass between the stopper 170 and the first guide part 130.

Further, the second support 300 may include a holder 330 that fixes the second chin strap 400 to the second support 300 (see FIGS. 2 and 3). Specifically, as shown in FIGS. 4a and 4b, a first bar 340 is formed at one end of the second support 300, and a first bar 340 is provided inside the first bar 340 and penetrated in the thickness direction. 3 through-holes 345 are formed. Further, a second bar 350 is formed at the end of the holder 330, and a fourth penetrating portion 355 is formed inside the second bar 350 in the thickness direction. The holder 330 is rotatably coupled to the second support 300 on the first bar 340 and the third penetrating part 345. Here, as shown in FIGS. 7a and 7b, the second chin strap 400 passes between the first bar 340 of the second support 300 and the second bar 350 of the holder 330, and the second bar 350 If the holder 330 is rotated relative to the second support 300 so as to approach the first bar 340 (see FIG. 7a), the second chin strap 400 is pressed between the second bar 350 and the first bar 340. and can be fixed. More specifically, the second chin strap 400 passes through the third penetration part 345 and the fourth penetration part 355, covers the second bar 350, and then passes through the third penetration part 345. Here, when the second chin strap 400 located on the second support body 300 (the second chin strap 400 before first passing through the third penetration part 345) is pulled from the helmet 500, the second bar 350 Since the holder 330 can be rotated to approach the bar 340, the second chin strap 400 is pressed and fixed between the second bar 350 and the first bar 340. Generally, as shown in FIG. 7A, when the chinstrap is fastened, a predetermined tension is applied to the second chinstrap 400 from the helmet 500 to the second support 300. Due to the tension of the second chin strap 400, the second bar 350 is pulled to the first bar 340, and the second chin strap 400 is pressed and fixed between the second bar 350 and the first bar 340. . On the other hand, as shown in FIG. 7b, if the holder 330 is rotated relative to the second support 300 so that the second bar 350 moves away from the first bar 340, the second chin strap 400 moves away from the second bar 350. and the first bar 340, and can freely move. Therefore, the wearer can adjust the length of the second chin strap 400 by rotating the holder 330 so that the second bar 350 moves away from the first bar 340.

Meanwhile, when the second support 300 is coupled to one side of the first support 100, the other side of the first support 100 is arranged to face the wearer's skin. Therefore, as shown in FIG. 8, in order to prevent the first support 100 made of plastic or the like from directly contacting the wearer's skin, a first support 100 is formed along the other surface of the first support 100. The chin strap 200 can be extended. As a result, the first chin strap 200, which is not the other surface of the first support 100, comes into contact with the wearer's skin, and the sweat of the wearer can be absorbed by the first chin strap 200. In order to extend the first chin strap 200 along the other surface of the first support body 100, a first guide part 130, a first penetration part 140, a second penetration part 150, etc. are formed in the first support body 100. Good too. Specifically, a first guide part 130 whose one surface is in contact with the first chin strap 200 is formed at one end of the first support body 100, and the first guide part 130 is formed to penetrate inside the first guide part 130 in the thickness direction. A first penetrating portion 140 is formed. Further, a second penetrating portion 150 is formed at the other end of the first support body 100 in the thickness direction. Accordingly, the first chin strap 200 passes through the first guide part 130 and the first penetrating part 140, extends along the other surface of the first support body 100, and then passes through the second penetrating part 150. That is, the first chin strap 200 passes through the first penetration part 140 and the second penetration part 150 formed at both ends of the first support body 100 and is connected to the first support body 100 . Extends along the other side.

Further, as shown in FIG. 8, markers 210 are provided on the first chin strap 200 at predetermined distances so that the relative position of the first support 100 with respect to the first chin strap 200 can be confirmed. It's okay. For example, the first chin strap 200 has dot-shaped markers 210 at regular intervals, so that the wearer can confirm the relative position of the first support 100 with respect to the first chin strap 200. Therefore, the wearer can adjust the position of the first support 100 while checking the sign 210, and can adjust the length of the first chin strap 200 from the helmet 500 to the first support 100.

You don't have to. For example, as shown in FIGS. 9 and 10, a protruding rotation limiting portion 117 may be formed on one surface of the first support body 100 (see FIG. 9). In addition, the second support 300 is coupled to the first support 100 within the rotation restriction part 117, and when the second support 300 forms a specific angle with respect to the first support 100, the second support 300 The side surface of the second support body 300 can be prevented from rotating by contacting the rotation restriction portion 117 . That is, the rotatable angle of the second support body 300 can be restricted by the rotation restriction portion 117 formed on the first support body 100.

11 and 12 are cross-sectional views of a chinstrap divider for a helmet according to still another embodiment of the present invention.

In the embodiment described above, the hook 315 is formed at the end of the protrusion 310, and the hook 315 is hooked onto the end of the insertion hole 120 (see FIG. 5A), but the hook 315 does not necessarily have to be used. For example, as shown in FIG. 11, after the protrusion 310 is inserted into the insertion hole 120, a screw 327 may be coupled to the end of the protrusion 310. Further, a washer 329 can be fastened to the screw 327, and since the washer 329 is engaged with the insertion hole 120, the first support 100 and the second support 300 are not separated by themselves. However, the washer 329 does not necessarily have to be fastened to the screw 327, and the screw 327 itself (for example, the head of the screw 327) may be hooked into the insertion hole 120.

Further, the protrusion 310 may not necessarily be formed on the second support body 300 and the insertion hole 120 may not necessarily be formed on the first support body 100. For example, as shown in FIG. 12, the surfaces of the first support 100 and the second support 300 that contact each other may be flat, or the first support 100 and the second support 300 may be connected to the fastening shaft 326. may be coupled so as to be rotatable with reference to. Here, the fastening shaft 326 may be, for example, a screw 327 fastened with a washer 329, but is not necessarily limited to this. All fastening structures that can be combined can be employed.

In the above description, the first and second chin straps 200 and 400 and the first and second supports 100 and 300 that are present on one side (left side) of the helmet 500 have been explained, but on the opposite side (right side) of the helmet 500, It goes without saying that the same structure also exists on the surface.

Although the present invention has been described in detail based on specific examples, this is only for specifically explaining the present invention, and the present invention is not limited thereto. Obviously, modifications and improvements may be made therein by those having ordinary skill in the art.

Any simple modification or modification of the present invention shall fall within the scope of the present invention, and the specific protection scope of the present invention will become clear from the appended claims.

According to the present invention, a first support body to which a first chin strap extending from the front side of the helmet is connected and a second support body to which a second chin strap is connected to the second chin strap extending from the rear side of the helmet side are separately provided, and the second support body is rotatable with respect to each other. By being movably coupled, it is possible to accommodate changes in the angle between the first chin strap and the second chin strap.
