Abstract
The invention relates to a helmet chin strap divider. The helmet chin strap divider according to the present embodiment includes: a first support (100) connected to a first chin strap (200) extending from a front part of a side surface of the helmet (500); and a second support (300) rotatably coupled to the first support (100) such that a second chin strap (400) extending from a rear portion of a side surface of the helmet (500) is connected thereto.
Description
Technical Field
The invention relates to a helmet chin strap divider.
Background
Helmets are used to protect the head of a wearer, and are classified into various types such as bicycle helmets, ski helmets, motorcycle helmets, and the like according to the use thereof.
The helmet has chin straps on both sides thereof such that the chin straps are tightened around the wearer's chin to secure the helmet to the wearer's head. In this case, the chin strap extends from the front and rear of the helmet side and is gathered under the wearer's ear in an overlapping manner. In conventional practice, helmets are configured with chin straps extending from a front portion thereof and chin straps extending from a rear portion thereof such that the chin straps overlap. Therefore, it is impossible to adjust the length of the chin strap extending from the front of the helmet and the length of the chin strap extending from the rear of the helmet, thereby making it difficult to correspond to various head types and causing interference between the chin strap and the ears of the wearer of the long face.
To solve such a problem, a divider is introduced at a portion where a chin strap extending from a front portion of a helmet overlaps with a chin strap extending from a rear portion of the helmet to allow the lengths of the chin straps to be adjusted with respect to each other, but according to a conventional divider, the chin strap extending from the front portion of the helmet and the chin strap extending from the rear portion of the helmet are gathered in one position, thus abruptly changing an angle therebetween, so that the chin strap may be twisted. When the chin strap is twisted, the degree of contact between the chin strap and the wearer's face is correspondingly reduced.

Detailed Description
The objects, features and advantages of the present invention will become more apparent from the detailed description set forth below and the accompanying drawings, in which corresponding parts in the embodiments of the present invention are designated by corresponding reference numerals, and repeated descriptions of the corresponding parts will be avoided. The terms such as first, second, etc. may be used to describe various elements, but these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. If it is determined that detailed explanation of the known technology related to the present invention makes the scope of the present invention unclear, explanation will be avoided for brevity of description.
Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 is a perspective view showing a helmet to which a helmet chin strap divider according to an embodiment of the present invention is applied, and fig. 2 and 3 are plan views showing an operation process of the helmet chin strap divider according to the present invention.
As shown in fig. 1 to 3, the helmet chin strap divider according to the present invention includes a first support 100 connected to a first chin strap 200 extending from a front part of a side surface of a helmet 500; and a second support 300 rotatably coupled to the first support 100 such that it is connected to the second chin strap 400 extending from the rear of the side surface of the helmet 500.
The helmet chin strap divider according to the present invention serves to overlap the first chin strap 200 extending from the front of the side surface of the helmet 500 and the second chin strap 400 extending from the rear of the side surface of the helmet 500 under the wearer's ears. In this case, the helmet chin strap divider according to the present invention includes a first support 100 connected to a first chin strap 200 and a second support 300 connected to a second chin strap 400.
Basically, the first support 100 and the second support 300 are rotatably coupled to each other. In this case, as shown in fig. 2 and 3, the relative position of the first support 100 and the first chin strap 200 can be adjusted by the locker 160, and the relative position of the second support 300 and the second chin strap 400 can be adjusted by the holder 330. That is, the length of the first chin strap 200 from the helmet 500 to the first support member 100 can be adjusted, and the length of the second chin strap 400 from the helmet 500 to the second support member 300 can be adjusted. Thus, if the length of the first chin strap 200 or the length of the second chin strap 400 is adjusted, the angle between the first chin strap 200 and the second chin strap 400 may be changed to allow the angle between the first support member 100 and the second support member 300 to be changed. For example, if the length of the first chin strap 200 from the helmet 500 to the first support member 100 is shortened, or if the length of the second chin strap 400 from the helmet 500 to the second support member 300 is shortened (see the variation of fig. 2 to 3), the angle between the first chin strap 200 and the second chin strap 400 is increased, thereby allowing the angle between the first support member 100 and the second support member 300 to be increased (from θ1 to θ2). Conversely, if the length of the first chin strap 200 from the helmet 500 to the first support member 100 becomes longer, or if the length of the second chin strap 400 from the helmet 500 to the second support member 300 becomes longer (refer to the variation of fig. 3 to 2), the angle between the first chin strap 200 and the second chin strap 400 decreases, thereby allowing the angle between the first support member 100 and the second support member 300 to decrease (from θ2 to θ1). As described above, even if the angle between the first and second chin straps 200 and 400 is varied according to the length of the first and second chin straps 200 and 400, the angle between the first and second supports 100 and 300 can be varied according to the varied angle between the first and second chin straps 200 and 400, thereby preventing the first and second chin straps 200 and 400 from being twisted.
The first support 100 and the second support 300 will be described in detail with reference to fig. 4 to 5. One surface of the first support 100 is disposed to face one surface of the second support 300. The second support 300 has a protruding portion 310 protruding from one surface thereof, and the first support 100 has an insertion hole 120 formed therethrough in a thickness direction thereof such that the protruding portion 310 is inserted into the insertion hole (see fig. 5 b). That is, the protruding portion 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 can be rotatably coupled to each other. Specifically, the protruding portion 310 is provided at an end thereof with a hook 315, and if the protruding portion 310 passes through the insertion hole 120, the hook 315 of the protruding portion 310 is locked on an end edge of the insertion hole 120 (see fig. 5 a). In this way, the hooks 315 of the protruding portion 310 are locked on the insertion holes 120, thereby preventing the first and second supports 100 and 300 from being arbitrarily separated from each other. In the above description, on the other hand, the protruding portion 310 is formed on the second support 300 and the insertion hole 120 is formed on the first support 100. However, of course, the protruding portion 310 may be formed on the first support 100 and the insertion hole 120 may be formed on the second support 300.
In addition, the protection device 320 is inserted into the protruding portion 310. In this case, the protruding portion 310 protrudes in a ring-shaped pattern to form an empty space 317 at the center thereof so as to be divided into one or more segments 319 (see fig. 5 b). In this case, the protection device 320 includes: a protective body 323 having a cylindrical shape inserted into the empty space 317 of the protruding portion 310; and a protection protrusion 325 radially protruding from the protection body 323 such that the protection protrusion is inserted into the segment 319. Accordingly, the protective body 323 is inserted into the empty space 317 of the protruding portion 310, and the protective protrusion 325 is inserted into the segment 319, so that the protective device 320 is inserted into the protruding portion 310. The protection device 320 prevents the protruding portion 310, particularly the hook 315, from being broken and further prevents the hook 315 from being arbitrarily separated from the insertion hole 120.
On the other hand, the second support 300 is rotatably coupled to the first support 100 only within a given angle with respect to the first support 100. Specifically, the first support 100 has a concave portion 110 formed on one surface thereof such that a step 115 is formed from the concave portion (see fig. 4 b). Further, the second supporter 300 is rotatably coupled to the concave portion 110, and when the second supporter 300 has a given angle with respect to the first supporter 100, a side surface of the second supporter 300 contacts the step 115 to prevent the second supporter 300 from rotating again. That is, the rotation angle of the second support 300 can be limited by the step 115 formed on the first support 100. More specifically, the steps 115 include a first step 115a facing one side surface of the second support 300 and a second step 115b facing the other side surface of the second support 300. In this case, if the second supporter 300 rotates in one direction (see fig. 2), one side surface of the second supporter 300 contacts the first step 115a to limit the rotation of the second supporter 300, and if the second supporter 300 rotates in the other direction (see fig. 3), the other side surface of the second supporter 300 contacts the second step 115b to limit the rotation of the second supporter 300. On the other hand, the rotatable angle of the second support 300 with respect to the first support 100 is, for example, 50 ° to 80 °. However, the rotatable angle of 50 ° to 80 ° is merely exemplary, and the rotatable angle may be freely changed without being limited thereto.
Further, the first support 100 has a locker 160 (see fig. 2 and 3) for fixing the first chin strap 200 thereto. Specifically, as shown in fig. 4a and 4b, the first support 100 has a first guide portion 130 formed on one end thereof so as to allow one surface to be in contact with the first chin strap 200. In addition, a locker 160 is located on the first guide portion 130 and rotatably coupled to the first support 100. Thus, as shown in fig. 6a, when the locker 160 has a first angle with respect to the first support 100 while rotating with respect to the first support 100, the locker 160 pressurizes the first chin strap 200 to allow the first chin strap 200 to be fixed to the first support 100. In contrast, when the locker 160 has the second angle with respect to the first support 100, as shown in fig. 6b, the locker 160 does not pressurize the first chin strap 200 to allow the first chin strap 200 to freely move, instead of being fixed to the first support 100. For example, when the locker 160 is at an angle of 180 ° with respect to the first support 100 (see fig. 6 a), the locker 160 can pressurize the first chin strap 200, and when the locker 160 has an angle of 90 ° with respect to the first support 100 (see fig. 6 b), the locker 160 cannot pressurize the first chin strap 200. More specifically, when the locker 160 is coupled to the first support 100 through the rotation shaft 163, the locker 160 is configured to have two surfaces 165 and 167 at different distances from the rotation shaft 163, and when the locker 160 rotates, it can pressurize the first chin strap 200 or cannot pressurize the first chin strap 200. 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 a second distance closer than the first distance from the rotation shaft 163 (see the enlarged portions of fig. 6a and 6 b). When the locker 160 has a first angle (e.g., 180 °) with respect to the first support 100 (see the enlarged portion of fig. 6 a), the first surface 165, which is a relatively long distance from the rotation shaft 163, pressurizes the first chin strap 200 together with the first guide part 130. Conversely, when the locker 160 has a second angle (e.g., 90 °) with respect to the first support 100 (see the enlarged portion of fig. 6 b), the second surface 167, which is a relatively short distance from the rotation shaft 163, does not pressurize the first chin strap 200 together with the first guide part 130. Accordingly, the locker 160 is rotated by the wearer with respect to the first chin bar 200 to fix the first chin bar 200 to the first support member 100 or to freely move the first chin bar 200, thereby adjusting the length of the first chin bar 200. On the other hand, the first support 100 has a stopper 170 for stopping the locker 160 when the locker 160 has a first angle (for example, 180 °) with respect to the first support 100 (see fig. 6 a). In this case, the stopper 170 and the first guide portion 130 are arranged side by side, and the first chin strap 200 passes through the space between the stopper 170 and the first guide portion 130.
Further, the second support 300 has a holder 330 (see fig. 2 and 3) for securing the second chin strap 400 thereto. Specifically, as shown in fig. 4a and 4b, the second support 300 has a first rod 340 formed at one end thereof and a third penetration portion 345 formed at the inner side of the first rod 340 in the thickness direction thereof. Further, the holder 330 has a second rod 350 formed on an end thereof and a fourth penetration portion 355 formed at an inner side of the second rod 350 in a thickness direction thereof. The holder 330 is rotatably coupled to the second support 300 on the first lever 340 and the third through hole 345. In this case, as shown in fig. 7a and 7b, the second chin strap 400 passes through a space between the first rod 340 of the second support 300 and the second rod 350 of the holder 330, and if the holder 330 rotates with respect to the second support 300 to allow the second rod 350 to approach the first rod 340 (see fig. 7 a), the second chin strap 400 is pressure-fixed between the second rod 350 and the first rod 340. More specifically, the second chin strap 400 passes through the third penetration part 345 and the fourth penetration part 355, covers the second rod 350, and passes through the third penetration part 345. In this case, if the second chin strap 400 positioned between the helmet 500 and the second support 300 is pulled (before passing through the third penetration portion 345 for the first time), the holder 330 rotates to allow the second rod 350 to approach the first rod 340, and thus, the second chin strap 400 is pressurized and fixed between the second rod 350 and the first rod 340. Generally, if the chin strap is fastened, as shown in fig. 7a, a given tension is applied to the second chin strap 400 positioned between the helmet 500 and the second support 300, and accordingly, the second lever 350 is pulled toward the first lever 340 by the tension of the second chin strap 400, so that the second chin strap 400 is pressure-fixed between the second lever 350 and the first lever 340. Conversely, as shown in fig. 7b, if holder 330 is rotated relative to second support 300 to allow second rod 350 to move away from first rod 340, second chin strap 400 is not pressurized between second rod 350 and first rod 340 and is therefore free to move. The length of the second chinstrap 400 is adjustable as the holder 330 is rotated relative to the second support 300 to allow the second lever 350 to move away from the first lever 340.
On the other hand, when the second support 300 is coupled to one surface of the first support 100, the other surface of the first support 100 faces the skin of the wearer. Thus, as shown in fig. 8, the first chin strap 200 extends along the other surface of the first support member 100 to prevent the first support member 100 made of plastic from directly contacting the wearer's skin. Accordingly, the first chin strap 200 (instead of the other surface of the first support member 100) contacts the wearer's skin, thereby enabling sweat of the wearer to be absorbed by the first chin strap 200. In order to allow the first chin strap 200 to extend along the other surface of the first support member 100, the first support member 100 includes a first guide portion 130, a first penetration portion 140, and a second penetration portion 150. Specifically, the first support 100 has a first guide portion 130 formed on one end thereof so as to allow one surface to be in contact with the first chin strap 200; and has a first penetration portion 140 formed at an inner side of the first guide portion 130 in a thickness direction thereof. Further, the first support 100 has a second penetration portion 150 formed on the other end thereof in the thickness direction thereof. After the first chin strap 200 sequentially passes through the first guide part 130 and the first penetration part 140, accordingly, the first chin strap 200 extends along the other surface of the first support 100 and then passes through the second penetration 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 member 100, and thus, the first chin strap 200 is connected to the first support member 100 while extending along the other surface of the first support member 100.
In addition, as shown in fig. 8, the first chin strap 200 has marks 210 provided thereon at regular intervals so as to check the relative position of the first support 100 with respect to the first chin strap 200. For example, the first chin strap 200 has dot-like marks 210 disposed thereon at regular intervals so that the wearer can check the relative position of the first support 100 with respect to the first chin strap 200. Thus, the position of the first support 100 can be adjusted while the wearer checks the mark 210, thereby adjusting the length of the first chin strap 200 positioned between the helmet 500 and the first support 100.
MODE OF THE INVENTION
Fig. 9 is a perspective view illustrating a helmet chin strap divider according to another embodiment of the present invention, and fig. 10 is a plan view illustrating a helmet chin strap divider according to another embodiment of the present invention. In one embodiment of the invention as described above, the second support 300 is only rotatable within a given angle with respect to the first support 100 by means of the stepped protrusion 115 (see fig. 4 b), but of course the stepped protrusion 115 may not be necessary. For example, as shown in fig. 9 and 10, the first support 100 has a rotation restricting member 117 protruding from one surface thereof (see fig. 9). Further, the second supporter 300 is coupled to the first supporter 100 within the rotation limiting member 117, and when the second supporter 300 has a given angle with respect to the first supporter 100, a side surface of the second supporter 300 contacts the rotation limiting member 117, thereby preventing the second supporter 300 from rotating again. That is, the rotation angle of the second supporter 300 can be limited by the rotation limiting member 117 on the first supporter 100.
Fig. 11 and 12 are cross-sectional views illustrating a helmet chin strap divider according to still another embodiment of the present invention.
In the embodiment of the present invention as described above, the hook 315 is formed on the end of the protruding portion 310 such that it is locked to the end edge of the insertion hole 120 (see fig. 5 a), but the hook 315 may not be necessary. For example, as shown in fig. 11, after the protruding portion 310 is inserted into the insertion hole 120, a screw 327 is coupled to an end edge of the protruding portion 310. Further, the washer 329 is installed around the screw 327, and the first support 100 and the second support 300 are not arbitrarily separated from each other since the washer 329 is locked to the insertion hole 120. However, washer 329 may not necessarily be installed around screw 327. That is, the screw 327 itself (e.g., the head of the screw 327) may be locked to the insertion hole 120.
Further, it is not necessarily required to form the protruding portion 310 on the second support 300 and the insertion hole 120 on the first support 100. For example, as shown in fig. 12, the contact surfaces of the first and second supports 100 and 300 are flat, and the first and second supports 100 and 300 are rotatably coupled to each other about the fastening shaft 326. In this case, the fastening shaft 326 may be a screw 327 to which the washer 329 is mounted, but not limited thereto, and all types of fastening structures such as an elastic material capable of rotatably coupling the first and second supports 100 and 300 to each other may be employed as the fastening shaft 326.
In the embodiment of the present invention as described above, the first and second chin straps 200 and 400 and the first and second supports 100 and 300 on one side (left side) of the helmet 500 have been explained, but of course, the same components as described above are also on the other side (right side) of the helmet 500.
Although the present invention has been described with reference to particular illustrative embodiments, the invention is not limited by the embodiments, but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
Thus, those skilled in the relevant art will appreciate that many modifications and variations are possible in light of the above teaching. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
