[Technical Field]

[0001] The present disclosure relates to a helmet sun visor control means.

[Background Art]

[0002] In general, wearing a helmet is required to protect a wearer's head when riding a motorcycle with high speed. Such a helmet has an opening at the front to secure a forward vision of a wearer. In this case, a shield that may be selectively opened or closed may be provided in the opening to block wind and dust introduced during operation. Also, a sun visor that may vertically move may be provided in the opening to block sunlight or the like from directly entering the wearer's eyes during the day.

[0003] In a helmet according to the prior art, as disclosed in the following patent literature of the prior art, a sun visor is vertically moved by using a wire. However, when the sun visor is moved by using the wire, it is difficult to maintain the sun visor at various heights by manipulation of the wearer. For example, the sun visor of the helmet according to the prior art may only remain completely open and completely closed, but may not be maintained at various heights by considering an angle of incidence of sunlight or a position of the wearer's eyes.

[0022] The objects, advantages, and features of the present disclosure will become more obvious from the following detailed description and preferred embodiments provided in relation to the accompanying drawings. In adding reference numerals to elements of each drawing in the specification, it should be noted that the same elements are denoted by the same reference numerals as much as possible even when they are shown on different drawings. Also, although the terms "first," "second," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. In the description of the present disclosure, certain detailed explanations of the related art are omitted when it is deemed that they may unnecessarily obscure the essence of the present disclosure.

[0023] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0024] FIG. 1 is a perspective view illustrating a helmet provided with a helmet sun visor control means, according to an embodiment of the present disclosure. FIGS. 2 to 4 are enlarged perspective views illustrating the helmet sun visor control means of FIG. 1.

[0025] As shown in FIGS. 1 to 4, a helmet sun visor control means according to the present embodiment, for controlling a sun visor 20 rotatably coupled to a helmet body 10, includes a controller 100 provided on a side of the helmet body 10, and the controller 100 supports the sun visor 20 so that the sun visor 20 maintains at least two heights with respect to the helmet body 10.

[0026] The helmet sun visor control means according to the present embodiment may be provided on the helmet body 10. The helmet body 10 for protecting a wearer's head may be formed of a material that may absorb impact. For example, the helmet body 10 includes an outer shell formed of a hard synthetic resin or the like and having high strength, and an absorber located inside the outer shell, formed of expanded polystyrene (EPS) or the like, and having appropriate strength and elasticity. Also, a pad or the like for improving wearing stability may be provided inside the absorber.

[0027] The sun visor 20 for blocking sunlight or the like from directly entering the wearer's eyes may extend in an arc shape to be located in front of the wearer's eyes. In this case, the sun visor 20 may be rotatably coupled to both sides (e.g., ratchets 30) of the helmet body 10 by using hinges or the like, may rotate with respect to the helmet body 10, and may be moved between a first position (see FIG. 2) and a second position (see FIG. 3). For example, the first position refers to a position at which the sun visor 20 is located in front of the wearer's eyes (see FIG. 2), and the second position refers to a position at which the sun visor 20 is accommodated in an upper receiving space of the helmet body 10 (see FIG. 3). In this case, the sun visor 20 may be moved between the first position and the second position, by a wire 40 or the like coupled to a side. However, although the sun visor 20 may be moved between the first position and the second position by using the wire 40, the sun visor 20 may not be maintained at a height between the first position and the second position by using only the wire 40. Accordingly, the helmet sun visor control means according to the present embodiment may maintain the sun visor 20 at various positions with respect to the helmet body 10 by employing the controller 100. The controller 100 will be described below in detail.

[0028] The controller 100 for supporting the sun visor 20 at various heights is provided on a side of the helmet body 10. For example, the controller 100 may be located on a lower side of the sun visor 20 (a lower side of the ratchet 30) (see FIG. 1). The controller 100 supports the sun visor 20 so that the sun visor 20 maintains at least two heights with respect to the helmet body 10 (see FIG. 2 or 4). In this case, the controller 100 may include a pivoting portion 110 and a contact portion 120. In detail, the pivoting portion 110 is provided on a side of the helmet body 10 (a lower side of the sun visor 20) to rotate around a certain axis. That is, the pivoting portion 110 may be located on a lower side of the sun visor 20, may be coupled to the helmet body 10, and may be rotated around the certain axis. Also, the contact portion 120 is provided on the pivoting portion 110 so that the center of the contact portion 120 is eccentric with respect to the certain axis of the pivoting portion 110 (see FIG. 5). In this case, the contact portion 120 may be formed to protrude on an outer surface of the pivoting portion 110, and a specific area (upper side) of a circumference of the contact portion 120 may contact and support the sun visor 20. The specific area contacting the sun visor 20 may be defined as a contact area 125. Because the contact portion 120 rotates together with the pivoting portion 110, a height of the contact area 125 of the contact portion 120 may change as the pivoting portion 110 rotates (because the pivoting portion 110 and the contact portion 120 are arranged to be eccentric). Accordingly, when the pivoting portion 110 rotates, the contact portion 120 whose center is eccentric with respect to the certain axis rotates, and a height of the contact area 125 contacting the sun visor 20 changes, and thus, a height of the sun visor 20 supported by the contact area 125 may change. As result, by changing a height of the contact area 125 of the contact portion 20 by manipulating the pivoting portion 110, the sun visor 20 may be supported so that the sun visor 20 maintains at least two heights with respect to the helmet body 10.

[0029] In more detail, because the center of the contact portion 120 is eccentric with respect to the certain axis of the pivoting portion 110, when the pivoting portion 110 is continuously rotated around the certain axis, a height of the contact area 125 of the contact portion 120 increases and then decreases. As such, when a height of the contact area 125 of the contact portion 120 increases and then decreases, a height of the sun visor 20 supported by the contact portion 120 may also increase and then decrease.

[0030] In order to increase and then decrease a height of the contact area 125 as the contact portion 120 rotates with the rotation of the pivoting portion 110, the contact portion 120 may be formed in a circular shape when viewed in a plane perpendicular to the certain axis. That is, the contact portion 120 may be formed in a substantially cylindrical shape on a top surface of the pivoting portion 110. However, the contact portion 120 may not necessarily be formed in a circular shape when viewed in a plane perpendicular to the certain axis, but may be formed in an elliptical shape or may include a protrusion, which will be described below.

[0031] Also, in detail, the sun visor 20 may include a rotating portion 21 rotatably coupled to the helmet body 10, a sun visor body 23 having an end coupled to the rotating portion 21, and a support 25 extending downward from the rotating portion 21. An end (lower end) of the support 25 may contact the contact portion 120. As the contact portion 120 rotates, the end of the support 25 may slide along an outer circumferential surface of the contact portion 120. Accordingly, when a height of the contact area 125 of the contact portion 120 changes according to the rotation of the pivoting portion 110, the support 25 may be moved upward or downward and the entire sun visor 20 may be moved upward or downward.

[0032] The controller 100 may further include a guide portion 200 that guides the pivoting portion 110. The guide portion 200 is located outside the pivoting portion 110. In this case, a protruding portion 210 protruding toward the pivoting portion 110 may be formed on the guide portion 200, and a recessed portion 115 into which the protruding portion 210 is inserted may be formed in the pivoting portion 110. As the protruding portion 210 of the guide portion 200 is inserted into the recessed portion 115 of the pivoting portion 110, the pivoting portion 110 may be coupled to the guide portion 200 and may be fixed at a specific position without being arbitrarily rotated. In detail, a plurality of recessed portions 115 may be formed, and may be arranged at certain angles along an outer circumferential surface of the pivoting portion 110. Accordingly, when the pivoting portion 110 is rotated, the protruding portion 210 may be inserted into one of the plurality of recessed portions 115, and the pivoting portion 110 may be fixed at a plurality of specific positions. For example, the recessed portion 115 may include first to sixth recessed portions formed in a counterclockwise direction. That is, six recessed portions 115 may be formed. In this case, when the pivoting portion 110 is rotated in a clockwise direction, the protruding portion 210 may be sequentially inserted into the first to sixth recessed portions, and the pivoting portion 110 may be fixed at six specific positions. As described above, because the pivoting portion 110 is fixed at a specific position by the guide portion 200, the contact portion 120 may support the sun visor 20 at a specific height.

[0033] Also, in order for the guide portion 200 to smoothly guide the rotation of the pivoting portion 110, when viewed in a plane perpendicular to the certain axis, the pivoting portion 110 may be formed in a circular shape and the guide portion 200 may be formed in an arc shape to surround at least a part of the outer surface of the pivoting portion 110. For example, the guide portion 200 may be formed in an arc shape that surrounds the rear of the pivoting portion 110, so that the front of the pivoting portion 110 is exposed. Accordingly, the wearer may manipulate the rotation of the pivoting portion 110 through the exposed front of the pivoting portion 110.

[0034] As the pivoting portion 110 rotates, the protruding portion 210 of the guide portion 200 should be inserted into the recessed portion 115 of the pivoting portion 110 or should be separated from the recessed portion 115 of the pivoting portion 110. To this end, two slits 220 may be formed in parallel in the guide portion 200 in a direction in which the pivoting portion 110 rotates (direction in which the guide portion 200 extends in an arc shape), an elastic area 230 may be formed between the two slits 220, and the protruding portion 210 may be formed in the elastic area 230. That is, because the two slits 220 are formed in the guide portion 200, the elastic area 230 located between the two slits 220 may be elastically deformed in a direction closer to or away from the pivoting portion 110. Accordingly, the protruding portion 210 formed in the elastic area 230 may be displaced in a direction closer to or away from the pivoting portion 110, and thus, the protruding portion 210 may be smoothly inserted into the recessed portion 115 or may be smoothly separated from the recessed portion 115.

[0035] Although the protruding portion 210 is formed on the guide portion 200 and the recessed portion 115 is formed in the pivoting portion 110 in the above description, the present disclosure is not limited thereto, and the protruding portion 210 may be formed on the pivoting portion 110 and the recessed portion 115 may be formed in the guide portion 200. In this case, a plurality of protruding portions 210 may be formed, and may be arranged at certain angles along the outer circumferential surface of the pivoting portion 110. Also, the recessed portion 115 may be formed in the elastic area 230 formed between the two slits 220 of the guide portion 200.

[0036] In addition, as shown in FIG. 6, an uneven portion 117 may be formed on the outer circumferential surface of the pivoting portion 110. Because a frictional force increases due to the uneven portion 117, the wearer may easily rotate the pivoting portion 110. Also, a display means 119 for displaying a height of the contact area 125 (specific area of the contact portion 120 contacting the sun visor 20) may be formed on the outer circumferential surface of the pivoting portion 110. The display means 119 may be a scale, and when a height of the contact area 25 is the lowest (when the sun visor 20 is at the lowest), the display means 119 (scale) may be located on the exposed front of the pivoting portion 110. Accordingly, the wearer may check the display means 119 (scale) on the exposed front of the pivoting portion 110, and may recognize that a current height of the sun visor 20 is the lowest.

[Mode for Invention]

[0037] FIGS. 7 to 14 are plan views illustrating a process of operating a helmet sun visor control means, according to an embodiment of the present disclosure. A process of operating a helmet sun visor control means according to the present embodiment will be described with reference to FIGS. 7 to 14.

[0038] First, as shown in FIGS. 7 and 8, when the wearer manipulates the wire 400, the sun visor 20 is rotated and moved downward, and the support 25 of the sun visor 20 contacts the contact area 125 of the contact portion 120. In this case, the protruding portion 210 of the guide portion 200 may be inserted into a first recessed portion 115a, and a height of the contact area 125 of the contact portion 120 may be the lowest, and thus, the sun visor 20 may be supported to maintain a first-stage height which is a lowest height.

[0039] Next, as shown in FIG. 9, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the first recessed portion 115a of the pivoting portion 110 and is inserted into a second recessed portion 115b. In this case, a height of the contact area 125 of the contact portion 120 may increase according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also increase, so that the sun visor 20 is supported to maintain a second-stage height that is higher than the first-stage height.

[0040] Next, as shown in FIG. 10, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the second recessed portion 115b and is inserted into a third recessed portion 115c. In this case, a height of the contact area 125 of the contact portion 120 may increase according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also increase, so that the sun visor 20 is supported to maintain a third-stage height that is higher than the second-stage height.

[0041] Next, as shown in FIG. 11, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the third recessed portion 115c of the pivoting portion 110 and is inserted into a fourth recessed portion 115d. In this case, a height of the contact area 125 of the contact portion 120 may increase according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also increase, so that the sun visor 20 is supported to maintain a fourth-stage height that is higher than the third-stage height.

[0042] Next, as shown in FIG. 12, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the fourth recessed portion 115d of the pivoting portion 110 and is inserted into a fifth recessed portion 115e. In this case, a height of the contact area 125 of the contact portion 120 may decrease according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also decrease, so that the sun visor 20 is supported to maintain the third-stage height that is lower than the fourth-stage height.

[0043] Next, as shown in FIG. 13, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the fifth recessed portion 115e and is inserted into a sixth recessed portion 115f. In this case, a height of the contact area 125 of the contact portion 120 may decrease according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also decrease, so that the sun visor 20 is supported to maintain the second-stage height that is lower than the third-stage height.

[0044] Next, as shown in FIG. 14, when the wearer manipulates the pivoting portion 110 to rotate the pivoting portion 110 in a clockwise direction, the protruding portion 210 of the guide portion 200 is separated from the sixth recessed portion 115f of the pivoting portion 110 and is inserted into the first recessed portion 115a. In this case, a height of the contact area 125 of the contact portion 120 may decrease according to the rotation of the pivoting portion 110, and thus, the sun visor 20 contacting the contact area 125 of the contact portion 120 may also decrease, so that the sun visor 20 is supported to maintain the first-stage height that is lower than the second-stage height.

[0045] As a result, when the wearer continuously rotates the pivoting portion 110 in one direction (e.g., a clockwise direction), a height of the contact area 125 of the contact portion 120 may increase and then decrease, and a height of the sun visor 20 may also increase and then decrease. That is, a height of the sun visor 20 may change in the order of the first-stage height (see FIG. 8) -> the second-stage height (see FIG. 9) -> the third-stage height (see FIG. 10) -> the fourth-stage height (see FIG. 11) -> the third-stage height (see FIG. 12) -> the second-stage height (see FIG. 13) -> the first-stage height (see FIG. 14).

[0046] However, the wearer does not necessarily have to control a height of the sun visor 20 by continuously rotating the pivoting portion 110 in one direction (e.g., a clockwise direction). A height of the sun visor 20 may increase regardless of which direction (a clockwise direction or a counterclockwise direction) the pivoting portion 110 is rotated at the first-stage height, and when the sun visor 20 is higher than a desired height, the sun visor 20 may be corrected to the desired height by rotating the pivoting portion 110 in the opposite direction. That is, the wearer may appropriately control a height of the sun visor 20 intuitively by rotating the pivoting portion 110 in both directions.

[0047] In addition, the reason why when the protruding portion 210 of the guide portion 200 is inserted into the second recessed portion 115b (see FIG. 9) and the protruding portion 210 of the guide portion 200 is inserted into the sixth recessed portion 115f (see FIG. 13), the sun visor 20 maintains the same height (the second-stage height), and when the protruding portion 210 of the guide portion 200 is inserted into the third recessed portion 115c (see FIG. 10) and the protruding portion 210 of the guide portion 200 is inserted into the fifth recessed portion 115e (see FIG. 12), the sun visor 20 maintains the same height (third-stage height) is that the contact portion 120 is formed in a circular shape (when viewed in a plane perpendicular to the certain axis). Accordingly, when viewed in a plane perpendicular to the certain axis, when the contact portion 120 is formed in an elliptical shape (see FIG. 15) or the protrusion 127 is formed on an outer surface of the contact portion 120 (see FIG. 16), the sun visor 20 may maintain a different height for each recessed portion 115 into which the protruding portion 210 of the guide portion 200 is inserted. That is, when viewed in a plane perpendicular to the certain axis, when the contact portion 120 is formed in an elliptical shape or the protrusion 127 is formed on an outer surface, various heights of the sun visor 20 as many as the number of recessed portions 115 may be maintained.

[0048] When viewed in a plane perpendicular to the certain axis, the contact portion 120 may be formed in an elliptical shape or a cam shape. In this case, the center of the contact portion 120 may not necessarily be eccentric with respect to the certain axis of the pivoting portion 100. That is, when the contact portion 120 is formed in an elliptical shape or a cam shape, even though the center of the contact portion 120 matches the certain axis of the pivoting portion 110, a height of the contact area 125 of the contact portion 120 contacting the sun visor 20 may change as the pivoting portion 110 rotates.

[0049] While the present disclosure has been described in detail with reference to the specific exemplary embodiment for specifically explaining the present disclosure, the present disclosure is not limited to the exemplary embodiment, and it is apparent that the alteration or modification may be made by one of ordinary skill in the art without departing from the technical spirit of the present disclosure.

[0050] The simple modification and alteration of the present disclosure are within the scope of the present disclosure, and the specific protection scope of the present disclosure may be clearly defined by the appended claims.
