[0033] Best practice

[0034] The objects, particular advantages, and novel features of this disclosure will become apparent from the following detailed description and exemplary embodiments taken in conjunction with the accompanying drawings. When adding reference numerals to elements in each figure of this disclosure, it should be noted that, although the same elements are depicted in different figures, they are given the same numbering whenever possible. Furthermore, terms such as "first," "second," etc., are used to distinguish one element from another, and these elements are not limited by these terms. In the following description of this disclosure, detailed descriptions of certain related known techniques are omitted where it is determined that such descriptions may unnecessarily obscure the subject matter of this disclosure.

[0035] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0036] Figures 1A and 1B are side views of a helmet having a shield rotation control device according to an embodiment of the present disclosure. Figure 2 This is an exploded perspective view of the shield rotation control device according to an embodiment of the present disclosure. Figure 3 This is a plan view of the shield rotation control device according to an embodiment of the present disclosure, and Figure 4 This is a rear view of a protective cover rotation control device according to an embodiment of the present disclosure.

[0037] As shown in Figure 1 to Figure 4 As shown, the protective cover rotation control device according to this embodiment includes a support member 100 and a stop device 200. The support member 100 supports the protective cover 20 and rotates relative to the base member 300. The stop device 200 is coupled to the support member 100 and provides an elastic force toward the base member 300. The support member 100 is stopped by the elastic force of the stop device 200.

[0038] As shown in Figures 1A and 1B, the helmet body 10 serves to protect the wearer's head. The helmet body 10 can be made of shock-absorbing material. For example, the helmet body 10 may include a high-strength rigid synthetic resin shell and a shock absorber made of expanded polystyrene (EPS) foam with appropriate strength and elasticity disposed within the shell. Pads may be present inside the shock absorber to improve the snug fit.

[0039] Furthermore, the helmet visor 20 serves to open and close the opening formed on the front side of the helmet body 10, and is rotatably coupled to both sides of the helmet body 10. Specifically, the helmet visor 20 can be rotatably coupled to the helmet body 10 via the support member 100 and the base member 300. Here, the helmet visor 20 can rotate relative to the helmet body 10 and can rotate from a first position to a second position. For example, the first position may refer to the position where the opening of the helmet visor 20 is closed (see FIG. 1A), and the second position may refer to the position where the opening of the helmet visor 20 is open (see FIG. 1B).

[0040] In addition, the chin guard 30 serves to protect the wearer's chin and can extend in an arc shape, positioning it on the front side of the wearer's chin. In this case, the chin guard 30 can be rotatable, with its two ends rotatably coupled to both sides of the helmet body 10. For example, the chin guard 30 can be rotatably coupled to the helmet body 10 via the arm 31 and the first link 32 and the second link 33 (see...). Figure 2 However, the first link 32 and the second link 33, as well as the arm 31, associated with the chin guard 30 have little direct relation to this disclosure, so detailed descriptions of the operation of the arm 31 and the first link 32 and the second link 33 are omitted, and some illustrations in the figures are omitted where necessary.

[0041] like Figure 2 and Figure 3 As shown, the shield rotation control device according to this embodiment may include a support member 100 and a stop device 200. Here, one side of the support member 100 may support the shield 20, while the other side may be rotatably coupled to the base member 300. Specifically, a fastening portion 105 is formed on one side of the support member 100, and the shield 20 may be coupled to the support member 100 when the end of the shield 20 is inserted into the fastening portion 105. Furthermore, a sliding portion 110 may be formed on the other side of the support member 100, and the sliding portion 110 may slide in contact with the periphery of the base member 300. For example, an arcuate sliding wall 310 may be formed on the periphery of the base member 300 facing the support member 100, and the sliding portion 110 of the support member 100 may also extend arcuately to correspond to the sliding wall 310, so that the sliding portion 110 of the support member 100 may slide along the sliding wall 310 of the base member 300. In this configuration, the support member 100 can rotate with the cover 20 relative to the base member 300.

[0042] Meanwhile, the support member 100 may include an extension 120 that extends to overlap with the base member 300. A stop device 200 may be coupled to the extension 120 to stop the support member 100 in a predetermined position. Here, the stop device 200 is configured with an elastic force toward the base member 300. Specifically, the stop device 200 may be rotatably coupled to the support member 100 about a rotation axis 210. In this case, the stop device 200 may include an elastic device for providing an elastic force to rotate the stop device 200 about the rotation axis 210 in one direction (counterclockwise based on the drawing). For example, the elastic device may be a torsion spring. As described above, when the elastic device provides an elastic force to the stop device 200 in one direction, the elastic force acts on the stop device 200 toward the base member 300 (sliding wall 310). In this situation, one side (upper end) of the stop device 200 can press the sliding wall 310 of the base member 300 (which extends to face the stop device 200) with elastic force to stop the support member 100. Finally, the support member 100 can be stopped in a predetermined position by the elastic force of the stop device 200.

[0043] However, one side (upper end) of the stop device 200 may not directly contact the sliding wall 310 of the base member 300. For example, a noise absorber member 220 may be present between the stop device 200 and the base member 300. Here, the noise absorber member 220 is rotatably coupled to the extension 120 of the support member 100. Therefore, when the stop device 200 presses the noise absorber member 220 by the elastic force of the stop device 200, the noise absorber member 220 rotates toward the sliding wall 310 of the base member 300 and contacts the sliding wall 310. That is, the noise absorber member 220 can contact the base member 300 by the elastic force of the stop device 200, and in this case, friction is generated between the noise absorber member 220 and the sliding wall 310 of the base member 300. The support member 100 can be stopped in a predetermined position by this friction. In addition, the noise absorber member 220 may be made of an elastomer to prevent noise that may occur due to movement in contact with the sliding wall 310. In this case, the noise absorber component 220 is not limited to a specific material and can be made of polysiloxane.

[0044] Meanwhile, the stop device 200 may include a first hook portion 230 formed in the shape of a hook. In this case, the first hook portion 230 may be formed on the other side (lower end) of the stop device 200. Furthermore, an auxiliary member (arm 31) coupled to the base member 300 and relating to the rotation of the chin guard 30 may have a second hook portion 240 formed in the shape of a hook, so as to be coupled to the first hook portion 230. In this case, the elastic device provides an elastic force in the direction (counterclockwise) in which the first hook portion 230 is coupled to the second hook portion 240. That is, by means of the elastic force of the elastic device, the elastic force acts toward the base member 300 (sliding wall 310) on one side (upper end) of the stop device 200, and the elastic force acts toward the second hook portion 240 on the other side (lower end) of the stop device 200. As described above, by the action of the elastic force of the elastic device, the first hook portion 230 and the second hook portion 240 can be coupled to each other, thereby fixing the stop device 200 and the support member 100 while preventing them from moving arbitrarily. However, when an external force, such as that of the wearer, is applied to the support member 100, the stop device 200 can rotate in the opposite direction to the elastic force (clockwise), the first hook portion 230 can separate from the second hook portion 240, and the support member 100 can rotate upward together with the cover 20. Although the foregoing description discloses that the second hook portion 240 is formed in the auxiliary member (arm 31), this disclosure is not necessarily limited thereto, and the second hook portion 240 can be formed directly in the base member 300.

[0045] like Figure 2 and Figure 4 As shown, the stop device 200 may include a protruding portion 250 projecting toward the base member 300. Here, the protruding portion 250 may protrude in a rod-like manner from one side (upper end) of the stop device 200. Simultaneously, the base member 300 may have a groove 320 extending in an arcuate shape along the direction of rotation of the support member 100. The protruding portion 250 of the stop device 200 may be inserted into the groove 320 of the base member 300 and slide along the groove 320 of the base member 300. Therefore, when the support member 100 rotates relative to the base member 300, the protruding portion 250 of the stop device 200 may slide along the groove 320 of the base member 300.

[0046] As described above, the elastic force of the elastic device acts on the stop device 200 in one direction (counterclockwise). Therefore, the elastic force can also act in one direction (based on...). Figure 2The force (counterclockwise) acts on the protrusion 250 formed on one side (upper end) of the stop device 200, and the protrusion 250 of the stop device 200 can slide to contact one side wall of the groove 320 of the base member 300. As described above, since the protrusion 250 of the stop device 200 contacts the groove 320 of the base member 300, the protrusion 250 can guide the support member 100 to rotate stably relative to the base member 300.

[0047] Furthermore, a first recessed portion 321, recessed in the direction of the elastic force of the elastic device provided to the protruding portion 250 (in the direction close to the sliding wall 310), can be formed at the first end (lower end) of the groove 320. The protruding portion 250 of the stop device 200 can be coupled to the first recessed portion 321. That is, since the elastic force of the elastic device acts on the protruding portion 250 of the stop device 200, the protruding portion 250 of the stop device 200 can rotate toward the first recessed portion 321 by the elastic force and can be disposed in the first recessed portion 321. As described above, when the protruding portion 250 of the stop device 200 is disposed in the first recessed portion 321 of the groove 320, the stop device 200 and the support member 100 can be fixed while preventing them from moving arbitrarily, but the force that fixes the stop device 200 and the support member 100 is substantially small. When an external force acts on the support member 100, the stop device 200 can move in the direction opposite to the elastic force (based on...). Figure 2 When the stop device 200 rotates clockwise, the protruding part 250 can separate from the first recessed part 321 of the groove 320, and the support member 100 can rotate upward together with the cover 20.

[0048] Simultaneously, when the first hook portion 230 is coupled to the second hook portion 240, the stop device 200 can move in the direction opposite to the elastic force (based on...). Figure 2 The groove 320 can rotate clockwise, and in this case, for the movement space of the protrusion 250 of the stop device 200, the groove 320 can have a first auxiliary recess 323 on the side opposite to the first recess 321.

[0049] Furthermore, a second recessed portion 325, recessed in the direction of the elastic force of the elastic device provided to the protruding portion 250 (in the direction close to the sliding wall 310), can be formed at the second end (upper end) of the groove 320. The protruding portion 250 of the stop device 200 can be coupled to the second recessed portion 325. That is, since the elastic force of the elastic device acts on the protruding portion 250 of the stop device 200, the protruding portion 250 of the stop device 200 can rotate toward the second recessed portion 325 by the elastic force and can be coupled to the second recessed portion 325. As described above, when the protruding portion 250 of the stop device 200 is coupled to the second recessed portion 325 of the groove 320, the stop device 200 and the support member 100 can be fixed, while preventing them from moving arbitrarily. However, when an external force, such as the force of a wearer, acts on the support member 100, the stop device 200 can move in the direction opposite to the elastic force (based on...). Figure 2 When rotated clockwise, the protruding portion 250 of the stop device 200 can separate from the second recessed portion 325 of the groove 320, and the support member 100 can rotate downward together with the cover 20.

[0050] Simultaneously, when the first hook portion 230 is coupled to the second hook portion 240 (when the auxiliary member (arm 31) rotates upward after the support member 100 rotates upward), the stop device 200 can move in the direction opposite to the elastic force (based on...). Figure 2 The groove 320 can rotate clockwise, and in this case, for the movement space of the protrusion 250 of the stop device 200, the groove 320 may have a second auxiliary recess 327 on the side opposite to the second recess 325.

[0051] Furthermore, to increase the coupling strength between the protruding portion 250 of the stop device 200 and the second recessed portion 325 of the groove 320, a first coupling portion 326 can be formed in the second recessed portion 325 of the groove 320, and a second coupling portion 255 can be formed in the protruding portion 250 of the stop device 200. Specifically, the first coupling portion 326 can extend such that it forms an angle on one side of the second recessed portion 325 of the groove 320, and the second coupling portion 255 can be recessed on one side of the protruding portion 250 of the stop device such that it forms an angle to correspond to the first coupling portion 326. As described above, the protruding portion 250 of the stop device 200 is coupled to the second recessed portion 325 by elastic force, and in this case, the first coupling portion 326 of the second recessed portion 325 and the second coupling portion 255 of the protruding portion 250 are in contact with each other, thereby enhancing the coupling strength between the protruding portion 250 of the stop device 200 and the second recessed portion 325 of the groove 320.

[0052] like Figure 4As shown, the shield rotation control device may include an elastic member 400 and a serrated portion 500 to control the rotation of the support member 100. Here, the elastic member 400 is disposed in the support member 100 such that it protrudes toward the base member 300 in a curved shape. For example, the elastic member 400 may be a snap-fit ​​spring. Additionally, the serrated portion 500 may be formed in the base member 300 such that it extends in the direction of rotation of the support member 100. For example, the serrated portion 500 may extend in an arc shape along the periphery of the base member 300 toward the elastic member 400. Therefore, when the elastic member 400 is coupled to the support member 100, the curved protrusion may be coupled to the serrated portion 500 formed in the base member 300. Finally, when the support member 100 rotates relative to the base member 300, the elastic member 400 may move along the serrated portion 500. Specifically, the serrated portion 500 may include a first groove 510 and a second groove 520. The curvature of the first groove 510 corresponds to the curvature of the elastic member 400 at one end (lower end), and the curvature of the second groove 520 corresponds to the curvature of the elastic member 400 at the other end (upper end). As described above, since the first groove 510 and the second groove 520, having curvatures corresponding to the curvature of the elastic member 400, are formed at both ends (upper and lower ends) of the serrated portion 500, the elastic member 400 can be inserted into the first groove 510 and the second groove 520. In this case, the elastic member 400 and the support member 100 can be fixed, preventing them from moving arbitrarily. Here, when the elastic member 400 is inserted into the first groove 510, the cover 20 can be in a first position (closed position of the opening), and when the elastic member 400 is inserted into the second groove 520, the cover 20 can be in a second position (open position of the opening). However, when an external force, such as that of the wearer, is applied to the support member 100, the elastic member 400 may separate from the first groove 510 and the second groove 520 as the elastic member 400 bends, and the support member 100 may rotate together with the cover 20.

[0053] Simultaneously, the serrated portion 500 may include multiple grooves 530, the curvature of which is greater than the curvature of the elastic member 400 between the first groove 510 and the second groove 520 (the radius of curvature of the multiple grooves 530 is smaller than the radius of curvature of the elastic member 400). Finally, since the multiple grooves 530, with a curvature greater than that of the elastic member 400, are formed between the two ends of the serrated portion 500, the elastic member 400 can pass through the multiple grooves 530 in a bent state. That is, when the wearer rotates the support member 100, the elastic member 400 bends and passes through the multiple grooves 530. In this case, the wearer can feel a clicking sound. Furthermore, when the wearer stops operating, the bent elastic member 400 can couple to the multiple grooves 530, causing the support member 100 to temporarily stop in a predetermined position.

[0054] Furthermore, the serrated portion 500 may include a third groove 540, the curvature of which corresponds to the curvature of the elastic member 400 located at a predetermined distance from the first groove 510 formed at one end (lower end). As described above, since the third groove 540, having a curvature corresponding to that of the elastic member 400, is formed at a predetermined distance from one end (lower end) of the serrated portion 500, the elastic member 400 can be inserted into the third groove 540. In this case, the elastic member 400 and the support member 100 can be fixed, preventing them from moving arbitrarily. Here, when the elastic member 400 is inserted into the third groove 540, the cover 20 can be in an initial open position (where the opening is partially open). However, when an external force, such as that of a wearer, is applied to the support member 100, the elastic member 400 may separate from the third groove 540 as the elastic member 400 bends, and the support member 100 may rotate together with the cover 20.

[0055] Although the foregoing description discloses that the elastic member 400 is formed in the support member 100 and the serrated portion 500 is formed in the base member 300, this disclosure is not necessarily limited thereto, and the elastic member 400 may be formed in the base member 300 and the serrated portion 500 may be formed in the support member 100.

[0056] like Figure 2 and Figure 3As shown, a protrusion 600 protruding toward the support member 100 is formed in the base member 300, such that it is held against the support member 100, and an elastic force can act on the protrusion 600 toward the base member 300. Specifically, the protrusion 600 may protrude in the shape of a hook, such that it is held against the upper side of the extension 120 of the support member 100. Therefore, when the protrusion 600 is held against the upper side of the extension 120 of the base member 300, the support member 100 can be fixed and prevented from moving arbitrarily. In this case, the cover 20 may be in a first position (closed position of the opening). However, since an elastic force acts on the protrusion 600 toward the base member 300, when an external force such as the wearer's force is applied to the support member 100, the protrusion 600 may separate from the extension 120 of the support member 100 as the protrusion 600 bends, and the support member 100 may rotate together with the cover 20.

[0057] Embodiments of the present invention

[0058] Figures 5 to 10 This is a side view showing the operation of the shield rotation control device according to an embodiment of the present disclosure, and is relative to... Figures 5 to 10 The operation process of the protective cover rotation control device according to this embodiment will be described.

[0059] First, such as Figure 5 As shown, when the cover 20 closes the opening (first position), the first hook portion 230 of the stop device 200 is coupled to the second hook portion 240 formed in the auxiliary member (arm 31) by the elastic force of the elastic device. Simultaneously, the elastic member 400 coupled to the support member 100 is inserted into the first groove 510 of the serrated portion 500 formed in the base member 300. Furthermore, the protrusion 600 formed in the base member 300 is held against the extension portion 120 of the support member 100. In summary, when the cover 20 closes the opening, the first hook portion 230 of the stop device 200 is coupled to the second hook portion 240, the elastic member 400 is coupled to the first groove 510 of the serrated portion 500, and the protrusion 600 is held against the extension portion 120 of the support member 100. Finally, when the cover 20 closes the opening, the support member 100 is secured by three fixing methods, thereby preventing arbitrary movement.

[0060] Subsequently, as Figure 6As shown, when the cover 20 rotates in the direction of the open opening, the stop device 200 rotates in the opposite direction to the elastic force (clockwise), and the first hook portion 230 of the stop device 200 separates from the second hook portion 240. Simultaneously, as the elastic member 400 coupled to the support member 100 bends, the elastic member 400 separates from the first groove 510. Furthermore, the protrusion 600 formed in the support member 100 bends and separates from the extension portion 120 of the support member 100. In summary, when the cover 20 rotates in the direction of the open opening, the first hook portion 230 of the stop device 200 separates from the second hook portion 240, the elastic member 400 separates from the first groove 510 of the serrated portion 500, and the protrusion 600 separates from the extension portion 120 of the support member 100. Finally, when the cover 20 rotates in the direction of the open opening, the three fixing methods for fixing the support member 100 can be cancelled, and the support member 100 can rotate relative to the base member 300.

[0061] Subsequently, as Figure 7 As shown, when the cover 20 rotates further in the direction of the open opening, the elastic member 400 coupled to the support member 100 is inserted into the third groove 540 of the serrated portion 500 formed in the base member 300. Therefore, the support member 100 can be fixed while preventing it from moving arbitrarily, and in this case, the cover 20 can be in the initial open position (where the opening is partially open).

[0062] Subsequently, as Figure 8 As shown, when the shield 20 rotates further in the direction of the open opening, the stop device 200 compresses the noise absorber member 220 by the elastic force of the elastic device, and the noise absorber member 220 thereby compresses the sliding wall 310 of the base member 300. Furthermore, the elastic member 400 bends and passes through the multi-groove 530. Therefore, when the wearer stops operating, the stop device 200 (noise absorber member 220) can compress the sliding wall 310 of the base member 300, and the bent elastic member 400 can couple to the multi-groove 530, stopping the support member 100 in a predetermined position.

[0063] Subsequently, as Figure 9As shown, when the cover 20 is fully opened (second position), the protruding portion 250 of the stop device 200 is coupled to the second recessed portion 325 formed at the second end (upper end) of the groove 320, and is coupled to the elastic member 400 of the support member 100 inserted into the second groove 520 of the serrated portion 500 formed in the base member 300. Finally, when the cover 20 is opened, the support member 100 can be fixed by two fixing methods to prevent it from moving arbitrarily. In particular, the first coupling portion 326 of the second recessed portion 325 and the second coupling portion 255 of the protruding portion 250 can contact and couple with each other, thereby enhancing the coupling strength between the protruding portion 250 of the stop device 200 and the second recessed portion 325 of the groove 320.

[0064] Subsequently, as Figure 10 As shown, when the cover 20 rotates in the direction of closing the opening, the stop device 200 rotates in the opposite direction to the elastic force (clockwise), the protruding portion 250 of the stop device 200 separates from the second recessed portion 325 of the groove 320, and the elastic member 400, coupled to the support member 100, separates from the second groove 520 as the elastic member 400 bends. Finally, when the cover 20 rotates in the direction of closing the opening, the two methods of fixing the support member 100 can be eliminated, and the support member 100 can rotate relative to the base member 300.

[0065] Furthermore, when the cover 20 rotates in the direction of closing the opening, the stop device 200 compresses the noise absorber member 220 by the elastic force of the elastic device, and the noise absorber member 220 thereby compresses the sliding wall 310 of the base member 300. Additionally, the elastic member 400 bends and passes through the multi-groove 530. Therefore, when the wearer stops operating, the stop device 200 (noise absorber member 220) can compress the sliding wall 310 of the base member 300, and the bent elastic member 400 can couple to the multi-groove 530, stopping the support member 100 in a predetermined position.

[0066] In the protective cover rotation control device according to this embodiment, when the protective cover 20 is in the closed position of the opening portion, when the protective cover 20 is in the initial open position of the opening portion, or when the protective cover 20 is in the fully open position of the opening portion, the support member 100 is fixed by a predetermined fixing method.

[0067] Furthermore, the shield rotation control device according to this embodiment can stably stop the shield 20 coupled to the support member 100 at a predetermined position by using the elastic stop device 200 to stop the support member 100 during rotation.

[0068] Although the present disclosure has been described in detail above with reference to specific embodiments, these specific embodiments are provided for the purpose of describing the present disclosure in detail, and the present disclosure is not limited thereto. Obviously, those skilled in the art can modify or change it within the scope of the technical spirit of the present disclosure.

[0069] Such modifications and alterations to this disclosure fall within the scope of this disclosure, and the scope of protection of this disclosure will become apparent from the appended claims.
