Description

Helmet chin strap divider

The present invention relates to a chin strap divider for a helmet.

The helmet protects the wearer's head, and may be a bicycle helmet, a ski helmet, or a motorcycle helmet, depending on the application.

In order to be fixed to the wearer's head, such a helmet has a structure that is provided with chin straps on both sides and fastened near the chin. At this time, the chin strap extends from the front and rear sides of the helmet, respectively, and is gathered together under the wearer's ear. The helmet according to the prior art is fixed in a form in which a chin strap extended from the front and a chin strap extended from the rear are gathered together. Accordingly, the length of the chin strap extended from the front and the length of the chin strap extended from the rear cannot be adjusted, so that it is difficult to cope with various heads, and interference occurs between the chin strap and the ear in the wearer with a long face.

In order to solve this problem, a divider that can adjust the relative length between the chin strap extending from the front and the chin strap extending from the rear has been introduced, which is arranged in a portion where the chin strap extending from the front and the chin strap extending from the rear are gathered together. . However, in the divider according to the prior art, since the chin strap extended from the front and the chin strap extended from the rear are collected at one point, a sharp angle change occurs, resulting in a problem that the chin strap is twisted. In this way, there is also a problem in that the adhesion between the chin strap and the face is deteriorated by twisting the chin strap.

In addition, terms such as "first" and "second" are used to distinguish one component from other components, and the component is not limited by the terms. Hereinafter, in describing the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the subject matter of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

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

1 to 3, the helmet chinstrap divider according to the present embodiment includes a first support 100 to which a first chin strap 200 extending from the front side of the helmet 500 is connected, and a first support It includes a second support (300) is coupled to the (100) so as to be rotatably connected to the second chin strap (400) extending from the rear side of the helmet (500).

Overall, the helmet chinstrap divider according to the present embodiment includes the first chinstrap 200 extending from the front side of the helmet 500 and the second chinstrap 400 extending from the rear side of the helmet 500 under the ear of the wearer. It plays a role in gathering together. Here, the helmet chinstrap divider according to the present embodiment includes a first support body 100 connected to the first chinstrap 200 and a second support body 300 connected to the second chinstrap 400.

Basically, the first support 100 and the second support 300 may be rotatably coupled to each other. In this case, as shown in FIGS. 2 to 3, the relative position of the first support 100 with respect to the first chin strap 200 can be adjusted with a locker 160, etc., and the second chin strap 400 2 The relative position of the support 300 can be adjusted with a holder 330 or the like. That is, adjusting 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 It is possible. In this way, if the length of the first chin strap 200 or the length of the second chin strap 400 is adjusted, the first support 100 and the first support 100 and the second chin strap 400 according to the angle change between the first chin strap 200 and the second chin strap 400 The angle between the second supports 300 may also be changed. For example, the length of the first chin strap 200 from the helmet 500 to the first support body 100 is shortened, or the second chin strap 400 from the helmet 500 to the second support body 300 When the length is shortened (see Fig. 2 -> Fig. 3), the angle between the first chin strap 200 and the second chin strap 400 increases, and accordingly, between the first support 100 and the second support 300 The angle of can be increased (θ1 -> θ2). Conversely, the length of the first chin strap 200 from the helmet 500 to the first support body 100 is increased, or the length of the second chin strap 400 from the helmet 500 to the second support body 300 is increased. When it becomes longer (see Fig. 3 -> Fig. 2), the angle between the first chin strap 200 and the second chin strap 400 decreases, and accordingly, the angle between the first support 100 and the second support 300 Can decrease (θ2 -> θ1). As described above, even if the angle between the first chin strap 200 and the second chin strap 400 changes according to the length of the first chin strap 200 or the length of the second chin strap 400, the changed first chin strap 200 ) And the second chinstrap 400, the angle between the first support 100 and the second support 300 is changed, so that the first chinstrap 200 or the second chinstrap 400 is twisted. Can be prevented.

Looking more specifically at the first and

second supports

100 and 300 with reference to FIGS. 4 to 5, one surface of the first support 100 and one surface of the second support 300 may be disposed to face each other. A protruding protrusion 310 may be formed on one surface of the second support 300, and an insertion hole 120 penetrating in the thickness direction may be formed in the first support 100 so that the protrusion 310 is inserted (Fig. 5b). That is, the protrusion 310 of the second support 300 is inserted into the insertion hole 120 of the first support 100 so that the first support 100 and the second support 300 are rotatably coupled to each other. It can be. 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 is at the end of the insertion hole 120. It can be caught (see Fig. 5A). In this way, the hook 315 of the protrusion 310 is caught in the insertion hole 120, so that the first support 100 and the second support 300 may not be arbitrarily separated. Meanwhile, in the above description, although it has been described that the protrusion 310 is formed in the second support 300 and the insertion hole 120 is formed in the first support 100, it is not limited thereto, and the first support ( The protrusion 310 may be formed in 100 and the insertion hole 120 may be formed in the second support 300.

Additionally, a protection means 320 may be inserted into the protrusion 310. Here, the protrusion 310 protrudes in an annular shape such that an empty space 317 is formed in the center, and may be divided into one or more divided sections 319 (see FIG. 5B ). At this time, the protection means 320 is a protective body 323 formed in a cylindrical shape to be inserted into the empty space 317 of the protrusion 310, and the protective body 323 protruding in the radial direction to be inserted into the divided section 319 It includes a protective protrusion 325. Therefore, while the protective body 323 is inserted into the empty space 317 of the protrusion 310, and the protective protrusion 325 is inserted into the divided section 319, the protection means 320 will be inserted into the protrusion 310. I can. The protection means 320 inserted into the protrusion 310 may be fixed to the protrusion 310 through bonding or screws. This protection means 320 serves to prevent damage to the protrusion 310, particularly the hook 315, and prevent the hook 315 from being arbitrarily separated from the insertion hole 120.

Meanwhile, the second support 300 may be rotatably coupled to the first support 100 only within a predetermined angle range. Specifically, a depression 110 is formed on one surface of the first support 100 to form a stepped portion 115 (see FIG. 4B ). In addition, the second support 300 is rotatably coupled to the recessed portion 110, and when the second support 300 achieves a specific angle with respect to the first support 100, the side surface of the second support 300 It is possible to prevent the second support 300 from rotating by contacting the stepped portion 115. That is, the angle at which the second support 300 can rotate through the step 115 formed on the first support 100 may be limited. More specifically, the stepped jaw 115 may include a first stepped jaw 115a facing one side of the second support 300 and a second stepped 115b facing the other side of the second support 300. have. At this time, when the second support 300 is rotated in one direction (see FIG. 2 ), one side of the second support 300 comes into contact with the first step 115a to limit the rotation of the second support 300, When the second support 300 is rotated in the other direction (refer to FIG. 3), the other side of the second support 300 comes into contact with the second step 115b, so that the rotation of the second support 300 may be limited. . Meanwhile, a range of a predetermined angle in which the second support 300 can rotate with respect to the first support 100 may be, for example, 50 degrees to 80 degrees. However, the predetermined angle range of 50 degrees to 80 degrees is illustrative and the scope of the present invention is not limited thereto.

Additionally, a locker 160 for fixing the first chin strap 200 may be provided on the first support 100 (see FIGS. 2 to 3 ). Specifically, as shown in FIGS. 4A to 4B, at one end of the first support 100, a first guide portion 130 having one surface in contact with the first chin strap 200 is formed. In addition, the locker 160 is disposed on the first guide portion 130 and is rotatably coupled to the first support 100. Accordingly, as shown in FIG. 6A, while the locker 160 rotates with respect to the first support 100, when the locker 160 achieves a first angle with the first support 100, the locker 160 The first chin strap 200 may be fixed to the first support 100 by pressing the first chin strap 200. On the other hand, as shown in FIG. 6B, when the locker 160 achieves a second angle with the first support 100, the locker 160 does not press the first chin strap 200 so that the first chin strap 200 It is not fixed to the first support 100 and can be freely moved. For example, when the locker 160 achieves 180 degrees with the first support 100 (see FIG. 6A), the locker 160 can press the first chin strap 200, and the locker 160 1 When achieving 90 degrees with the support 100 (see FIG. 6B), the locker 160 may not press the first chin strap 200. More specifically, when the locker 160 is coupled to the first support 100 and the rotation shaft 163, the locker 160 includes two

surfaces

165 and 167 having different distances from the rotation shaft 163. Thus, as the locker 160 rotates, the first chin strap 200 may or may not be pressed. That is, the locker 160 includes a first surface 165 spaced a first distance from the rotation shaft 163 and a second surface 167 spaced apart from the rotation shaft 163 a second distance closer than the first distance. Can (see enlarged view of Figs. 6A to 6B). Therefore, when the locker 160 achieves a first angle (for example, 180 degrees) with the first support 100 (see enlarged view of FIG. 6A), the first surface 165 relatively far from the rotation shaft 163 ) May press the first chin strap 200 together with the first guide part 130. On the other hand, when the locker 160 achieves a second angle (eg, 90 degrees) with the first support 100 (see enlarged view of FIG. 6B), the second surface 167 relatively close to the rotation shaft 163 ) May not press the first chin strap 200 together with the first guide part 130. Eventually, the wearer rotates the locker 160 to the first support 100 to fix the first chin strap 200 to the first support 100 or make the first chin strap 200 movable to increase the length of the first chin strap 200. Can be adjusted. On the other hand, when the locker 160 at the first support 100 achieves a first angle (for example, 180 degrees) with the first support 100 (see FIG. 6A), a stopper 170 for stopping the locker 160 ) Can be formed. In this case, the stopper 170 is disposed in parallel with the first guide portion 130, and the first chin strap 200 may pass between the stopper 170 and the first guide portion 130.

In addition, a holder 330 for fixing the second chin strap 400 may be provided on the second support 300 (see FIGS. 2 to 3 ). Specifically, as shown in FIGS. 4A to 4B, at one end of the second support 300, the first bar 340 and the third through part 345 penetrated in the thickness direction inside the first bar 340. ) Is formed. In addition, at the ends of the holder 330, the second bar 350 and the fourth penetrating portion 355 penetrating in the thickness direction are formed inside the second bar 350. The holder 330 is rotatably coupled with the second support 300 on the first bar 340 and the third through portion 345. At this time, as shown in FIGS. 7A to 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 When the holder 330 is rotated with respect to the second support 300 so that the bar 350 is close to the first bar 340 (refer to FIG. 7A), the second chin strap 400 is 1 It can be fixed by pressing between the bars 340. More specifically, the second chin strap 400 passes through the third penetrating portion 345 and the fourth penetrating portion 355, then surrounds the second bar 350, and then the third penetrating portion 345 Can pass. At this time, when the second chin strap 400 (the second chin strap 400 before passing through the first third penetrating portion 345) from the helmet 500 to the second support 300 is pulled, the second bar 350 The holder 330 may be rotated so that) is close to the first bar 340, and accordingly, the second chin strap 400 may be pressed and fixed between the second bar 350 and the first bar 340. have. In general, as shown in FIG. 7A, when the chin strap is fastened, tension is applied to the second chin strap 400 from the helmet 500 to the second support 300, so that the tension of the second chin strap 400 is applied. As a result, the second bar 350 is pulled in the direction of the first bar 340, so that the second chin strap 400 may be pressed and fixed between the second bar 350 and the first bar 340. Conversely, as shown in FIG. 7B, when the holder 330 is rotated with respect to the second support 300 so that the second bar 350 is away from the first bar 340, the second chin strap 400 is 2 It is not pressed between the bar 350 and the first bar 340, it may be freely movable. Accordingly, the wearer may adjust the length of the second chin strap 400 by rotating the holder 330 so that the second barga 350 is away from the first bar 340.

Meanwhile, when the second support 300 is coupled to one surface of the first support 100, the other surface of the first support 100 is disposed to face the wearer's skin. Therefore, as shown in FIG. 8, in order to prevent the first support 100 formed of plastic, etc. from directly contacting the wearer's skin, the first chin strap 200 is provided along the other surface of the first support 100. Can be extended. As a result, the first chin strap 200 is in contact with the wearer's skin rather than the other surface of the first support 100, so that the wearer's sweat can be absorbed by the first chin strap 200. In order for the first chin strap 200 to extend along the other surface of the first support 100, the first support 100 includes a first guide part 130, a first through part 140, and a second through part ( 150) and the like may be formed. Specifically, at one end of the first support 100, a first guide portion 130 having one surface in contact with the first chin strap 200 and a first through portion penetrated in the thickness direction inside the first guide portion 130 140 is formed. In addition, a second through part 150 penetrating in the thickness direction is formed at the other end of the first support 100. Accordingly, the first chin strap 200 passes through the first through portion 140 through the first guide portion 130 and then extends along the other surface of the first support body 100, and thereafter, the second through portion 150 ) Can pass. That is, the first chinstrap 200 passes through the first through portions 140 and the second through portions 150 formed at both ends of the first support body 100, while being connected to the first support body 100 It can be extended along the other surface of the support (100).

In addition, as shown in FIG. 8, in order to confirm the relative position of the first support body 100 with respect to the first chin strap 200, a mark 210 may be present at each predetermined distance on the first chin strap 200. . For example, a dot-shaped mark 210 is present on the first chin strap 200 at predetermined distances, so that the wearer can check the relative position of the first support body 100 with respect to the first chin strap 200. have. Therefore, the wearer can adjust the position of the first support body 100 while checking the mark 210, through which the length of the first chin strap 200 from the helmet 500 to the first support body 100 can be adjusted. have.

In the above-described embodiment, it has been described that the second support 300 is rotatable only within a predetermined angle range with respect to the first support 100 by the step 115 (see FIG. 4B), but the step 115 must be formed. Is not. For example, as shown in FIGS. 9 to 10, a protruding rotation limiting portion 117 may be formed on one surface of the first support 100 (see FIG. 9 ). In addition, the second support 300 is coupled within the rotation limiting portion 117, and when the second support 300 achieves a specific angle with respect to the first support 100, the side of the second support 300 rotates. It is possible to prevent the second support 300 from rotating by contacting the limiting portion 117. That is, the angle at which the second support 300 can rotate through the rotation limiting portion 117 formed on the first support 100 can be limited.

In the above-described embodiment, the hook 315 is formed at the end of the protrusion 310, and it has been described that the hook 315 is hooked to the end of the insertion hole 120 (see FIG. 5A), but the hook 315 is always You don't have to use it. 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 an end of the protrusion 310. In addition, a washer 329 may be fastened to the screw 327, and since the washer 329 is caught in the insertion hole 120, the first support 100 and the second support 300 cannot be separated arbitrarily. I can. However, the washer 329 is not necessarily fastened to the screw 327, and the screw 327 itself (eg, the head of the screw 327) may be caught in the insertion hole 120.
