Abstract
The present invention relates to a helmet chinstrap divider. The helmet chinstrap divider according to this embodiment includes: a first support (100) connected to a first lower chinstrap (200) extending from a front portion of a side surface of a 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 present invention relates to a helmet chinstrap divider.
Background
Helmets are used to protect the head of a wearer and are classified into various types such as a bicycle helmet, a ski helmet, a motorcycle helmet, etc. according to their uses.
The helmet has chin straps on both sides thereof such that the chin straps tighten around the wearer's chin to secure the helmet to the wearer's head. In this case, the chinstrap extends from the front and rear of one side of the helmet and gathers overlappingly under the wearer's ears. In conventional practice, the helmet is configured to have a chin strap extending from its front and a chin strap extending from its rear, such that the chin straps converge overlappingly. Therefore, it is impossible to adjust the length of the chin strap extending from the front portion of the helmet and the length of the chin strap extending from the rear portion of the helmet, thereby making it difficult to correspond to various head types and causing interference between the chin strap and the ears of a long-face wearer.
To solve such a problem, a divider has been introduced at a portion where a chin strap extending from a front portion of a helmet and a chin strap extending from a rear portion of the helmet are overlappingly gathered to allow lengths of the chin straps to be adjusted with respect to each other, but according to the 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 at one position, thus sharply changing an angle therebetween, so that the chin straps 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 explanation of the corresponding parts will be avoided. 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. If it is determined that detailed explanation of well-known technology related to the present invention makes the scope of the present invention unclear, the explanation will be avoided for the brevity of description.
Now, embodiments of the present invention will 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 separator according to an embodiment of the present invention is applied, and fig. 2 and 3 are plan views showing the operation process of the helmet chin strap separator 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 portion 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 a second chin strap 400 extending from a rear portion of a side surface of the helmet 500.
The helmet chin strap separator according to the present invention serves to superpose the first chin strap 200 extending from the front portion of the side surface of the helmet 500 and the second chin strap 400 extending from the rear portion of the side surface of the helmet 500 under the ears of the wearer. In this case, the helmet chinstrap divider according to the present invention includes a first support 100 connected to the first chinstrap 200 and a second support 300 connected to the second chinstrap 400.
Basically, the first and second supports 100 and 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 lower chin strap 200 can be adjusted by the locker 160, and the relative position of the second support 300 and the second lower chin strap 400 can be adjusted by the keeper 330. That is, the length of the first chin strap 200 from the helmet 500 to the first support 100 can be adjusted, and the length of the second chin strap 400 from the helmet 500 to the second support 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 100 and the second support 300 to also be changed. For example, if the length of the first chin strap 200 from the helmet 500 to the first support 100 is shortened, or if the length of the second chin strap 400 from the helmet 500 to the second support 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, allowing the angle between the first support 100 and the second support 300 to be increased (from θ 1 to θ 2). Conversely, if the length of the first chin strap 200 from the helmet 500 to the first support 100 becomes longer, or if the length of the second chin strap 400 from the helmet 500 to the second support 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 100 and the second support 300 to decrease (from θ 2 to θ 1). As described above, even if the angle between the first and second chin straps 200 and 400 is changed according to the length of the first chin strap 200 or the length of the second chin strap 400, the angle between the first and second supports 100 and 300 can be changed according to the changed 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 and second supports 100 and 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 to penetrate 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 and second supports 100 and 300 can be rotatably coupled to each other. Specifically, the protruding part 310 is provided at an end thereof with a hook 315, and if the protruding part 310 passes through the insertion hole 120, the hook 315 of the protruding part 310 is locked on an end edge of the insertion hole 120 (see fig. 5 a). In this way, the hook 315 of the protruding portion 310 is locked on the insertion hole 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 protector 320 is inserted into the protrusion 310. In this case, the protruding part 310 protrudes in a pattern of a ring shape to form an empty space 317 at the center thereof such that it is 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 protrusion part 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 protection body 323 is inserted into the empty space 317 of the protruding portion 310, and the protection protrusion 325 is inserted into the segment 319, so that the protection device 320 is inserted into the protruding portion 310. The protector 320 prevents the protrusion 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 support 300 is rotatably coupled to the concave portion 110, and when the second support 300 has a given angle with respect to the first support 100, a side surface of the second support 300 is in contact with the step 115 to prevent the second support 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 support 300 rotates in one direction (see fig. 2), one side surface of the second support 300 contacts the first step 115a to restrict the rotation of the second support 300, and if the second support 300 rotates in the other direction (see fig. 3), the other side surface of the second support 300 contacts the second step 115b to restrict the rotation of the second support 300. On the other hand, for example, the rotatable angle of the second support 300 with respect to the first support 100 is 50 ° to 80 °. However, the rotatable angle of 50 ° to 80 ° is only exemplary, and the rotatable angle may be freely changed without being limited thereto.
In addition, the first support 100 has a locker 160 for fixing the first lower jaw band 200 thereto (see fig. 2 and 3). Specifically, as shown in fig. 4a and 4b, the first support 100 has a first guide portion 130 formed on one end thereof such that one surface is allowed to contact the first lower chin strap 200. In addition, the 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 lower jaw band 200 to allow the first lower jaw band 200 to be fixed to the first support 100. In contrast, as shown in fig. 6b, when the locker 160 has a second angle with respect to the first support 100, the locker 160 does not pressurize the first lower jaw band 200 to allow the first lower jaw band 200 to move freely, rather than 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. 6a), the locker 160 can pressurize the first lower jaw band 200, and when the locker 160 has an angle of 90 ° with respect to the first support 100 (see fig. 6b), the locker 160 cannot pressurize the first lower jaw band 200. More specifically, when the locker 160 is coupled to the first support 100 by the rotation shaft 163, the locker 160 is configured to have two surfaces 165 and 167 having different distances from the rotation shaft 163, and when the locker 160 is rotated, it can pressurize the first lower jaw band 200 or cannot pressurize the first lower jaw band 200. That is, the locker 160 includes a first surface 165 spaced apart from the rotational axis 163 by a first distance and a second surface 167 spaced apart from the rotational axis 163 by a second distance closer than the first distance (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. 6a), the first surface 165, which is a relatively long distance from the rotational axis 163, pressurizes the first lower jaw band 200 together with the first guide portion 130. Conversely, when the lock 160 has a second angle (e.g., 90 °) relative to the first support 100 (see the enlarged portion of fig. 6b), the second surface 167, which is a relatively short distance from the rotational axis 163, does not press the first lower jaw band 200 together with the first guide portion 130. Accordingly, the lock 160 is rotated relative to the first lower jaw band 200 by the wearer to fix the first lower jaw band 200 to the first support 100 or to freely move the first lower jaw band 200, thereby adjusting the length of the first lower jaw band 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 (e.g., 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 lower jaw band 200 passes through a space between the stopper 170 and the first guide portion 130.
Further, the second support 300 has a holder 330 for fixing the second chin strap 400 thereto (see fig. 2 and 3). 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 through portion 345 formed at an inner side of the first rod 340 in a thickness direction thereof. Further, the holder 330 has a second rod 350 formed on an end thereof and a fourth penetration portion 355 formed on 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 rod 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 relative to the second support 300 to allow the second rod 350 to approach the first rod 340 (see fig. 7a), the second chin strap 400 is press-fixed between the second rod 350 and the first rod 340. More specifically, the second chin strap 400 passes through the third through portion 345 and the fourth through portion 355, covers the second rod 350, and passes through the third through portion 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 press-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 by the tension of the second chin strap 400, accordingly, the second rod 350 is pulled toward the first rod 340, so that the second chin strap 400 is press-fixed between the second rod 350 and the first rod 340. Conversely, as shown in fig. 7b, if the keeper 330 is rotated relative to the second support 300 to allow the second rod 350 to move away from the first rod 340, the second chinstrap 400 is not pressurized between the second rod 350 and the first rod 340 and thus is free to move. The length of the second chin strap 400 is adjustable when the keeper 330 is rotated relative to the second support 300 to allow the second rod 350 to move away from the first rod 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. Accordingly, as shown in fig. 8, the first lower chin strap 200 extends along the other surface of the first support 100 to prevent the first support 100 made of plastic from directly contacting the skin of the wearer. Accordingly, the first lower chin strap 200 (not the other surface of the first support 100) is in contact with the wearer's skin, thereby enabling sweat of the wearer to be absorbed by the first lower chin strap 200. To allow the first lower chin strap 200 to extend along the other surface of the first support 100, the first support 100 includes a first guide portion 130, a first through portion 140, and a second through portion 150. Specifically, the first support 100 has a first guide portion 130 formed on one end thereof such that one surface is allowed to contact the first lower 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 through portion 150 formed on the other end thereof in the thickness direction thereof. After the first lower chin strap 200 passes through the first guide portion 130 and the first through portion 140 in sequence, accordingly, the first lower chin strap 200 extends along the other surface of the first support 100 and then passes through the second through portion 150. That is, the first lower chin strap 200 passes through the first and second through portions 140 and 150 formed at both ends of the first support 100, and thus, the first lower chin strap 200 is connected to the first support 100 while extending along the other surface of the first support 100.
In addition, as shown in fig. 8, the first lower chin strap 200 has marks 210 disposed thereon at regular intervals in order to check the relative position of the first support 100 with respect to the first lower chin strap 200. For example, the first lower chin strap 200 has dot-like markings 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 lower chin strap 200. Accordingly, 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 chinstrap divider according to another embodiment of the present invention, and fig. 10 is a plan view illustrating a helmet chinstrap divider according to another embodiment of the present invention. In one embodiment of the present invention as described above, the second support 300 can only be rotated at a given angle with respect to the first support 100 by means of the stepped protrusion 115 (see fig. 4b), 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 (see fig. 9) protruding from one surface thereof. Further, the second support 300 is coupled to the first support 100 within the rotation limiting member 117, and when the second support 300 has a given angle with respect to the first support 100, a side surface of the second support 300 is in contact with the rotation limiting member 117, thereby preventing the second support 300 from rotating again. That is, the rotation angle of the second support 300 can be limited by the rotation limiting member 117 on the first support 100.
Fig. 11 and 12 are cross-sectional views illustrating a helmet chinstrap divider according to yet 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 part 310 such that the hook is locked to the end edge of the insertion hole 120 (see fig. 5a), 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 since the washer 329 is locked to the insertion hole 120, the first and second supports 100 and 300 are not arbitrarily separated from each other. However, the washer 329 may not necessarily be mounted around the 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 protrusion 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 a washer 329 is mounted, but is not limited thereto, and all types of fastening structures capable of rotatably coupling the first and second supports 100 and 300 to each other, such as an elastic material, 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 located on one side (left side) of the helmet 500 have been explained, but of course, the same components as described above are also located on the other side (right side) of the helmet 500.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be understood that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
Accordingly, one of ordinary skill 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.
