Description

Technical Field

[0001] The present invention relates to a head protection device, and more specifically to a head protection device with a structure that can improve driving performance.

Background Art

[0002] A head protection device, commonly referred to as a helmet, is used to protect the wearer's head part.

[0003] Typically, helmets are equipped with a visor that serves as a shield. The visor is designed to prevent the inflow of outside air while driving and to prevent foreign substances such as stones on the road from directly hitting the face.

[0004] The visor is coupled to a frame that protects a head part. Conventionally, since the visor is rotatably coupled to the frame, a predetermined clearance is generally generated in a portion where the visor is seated on the frame.

[0005] When an impact is applied to the visor from the outside while the predetermined clearance is generated, there is also a risk that the visor may randomly come off the frame and be excessively introduced into the wearer's face.

[0006] Therefore, for the wearer's safety, the coupled state of the frame and visor must be maintained stably. To this end, a separate member is generally provided to support the visor seated on the frame.

[0007] However, the frame and visor are formed to have similar overall shapes. Accordingly, the member which is separately provided to support the visor may protrude to an outside of the frame or visor.

[0008] In this case, a protruding portion may appear on the surface of the helmet, which may increase air resistance when driving. Accordingly, there is a risk that driving performance will deteriorate, and noise will be generated due to air resistance, thereby making it difficult for the wearer to drive safely.

[0009] Korean Patent Laid-Open Publication No. 10-2018-0106289 discloses a shield attachment/detachment device for a helmet. Specifically, disclosed is a shield attachment/detachment device for a helmet in which the shield attachment/detachment and opening/closing angles can be adjusted by engaging the retracting portion, the engaging portion and the left and right sides.

[0010] The Korean utility model publication discloses a helmet visor combination structure. Specifically, disclosed is a structure for coupling a helmet and a visor through coupling of hooks formed on both side surfaces of a helmet body with hooks formed on both ends of the visor.

[0011] However, the above related art documents only provide a method for coupling the helmet itself and the visor. In other words, the above related art documents do not provide a method for preventing risks due to arbitrary separation or elastic deformation of the visor coupled to the helmet.

In order to clearly explain the present invention, parts that are not related to the description have been omitted in the drawings, and identical or similar components are assigned the same reference numerals throughout the specification.

[0042] Terms and words used in the present specification and claims should not be construed as limited to their usual or dictionary definition, and they should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that inventors may appropriately define the terms and concept in order to describe their own invention in the best way.

[0043] Accordingly, the embodiments described in the present specification and the configurations shown in the drawings correspond to preferred embodiments of the present invention, and do not represent all the technical spirit of the present invention, and thus, the configurations may have various examples of equivalent and modification that can replace them at the time of filing the present invention.

[0044] In the following description, in order to clarify the characteristics of the present invention, the descriptions of some components may be omitted.

[0045] The terms "top", "bottom", "left", "right", "front" and "back" used in the following description will be understood with reference to the coordinate system illustrated in FIG. 1.

[0046] Referring to FIGS. 1 to 8, a head protection device 10 according to an embodiment of the present invention is disclosed.

[0047] The head protection device 10 according to an embodiment of the present invention includes a visor 200 for blocking outside air flowing in from a front side while driving. The visor 200 is rotatably coupled to an outer frame 100, and a portion of the visor 200 may be seated on the outer frame 100.

[0048] Accordingly, the head protection device 10 according to an embodiment of the present invention includes a visor holder 300, and it presses the visor 200 seated on the outer frame 100 in a direction toward the outer frame 100. The visor holder 300 may be configured to press the visor 200 depending on the state of the visor 200, that is, whether it is seated on the outer frame 100.

[0049] With the above configuration, the seating state of the outer frame 100 and the visor 200 may be stably maintained. Additionally, even when an external force is applied to the visor 200, a situation in which the visor 200 enters the interior of the outer frame 100 may be prevented.

[0050] At the same time, the visor holder 300 is configured to rotate toward the outer frame 100 when the visor 200 is seated on the outer frame 100. Accordingly, the visor holder 300 does not protrude to an outside of the outer frame 100 or the visor 200, thereby preventing the deterioration of driving performance or the generation of excessive driving noise.

[0051] Referring to FIGS. 1 to 8, the head protection device 10 according to the illustrated embodiment includes an outer frame 100, a visor 200 and a visor holder 300.

[0052] The outer frame 100 forms an outer shape of the head protection device 10. A space is formed inside the outer frame 100 to receive the wearer's head part. The outer frame 100 may protect the wearer's head part from external impacts and the like.

[0053] The outer frame 100 may be made of a lightweight yet highly rigid material. This is to effectively protect the wearer's head part, while minimizing the feeling of foreign substances or weight felt by the wearer. In one embodiment, the outer frame 100 may be formed of a synthetic resin material such as reinforced plastic.

[0054] The outer frame 100 may be shaped to receive and protect the wearer's head and minimize air resistance while driving. In the illustrated embodiment, the outer frame 100 is shaped like a sphere, similar to the wearer's head part.

[0055] The visor 200 is rotatably coupled to the outer frame 100. The visor 200 may be rotated clockwise or counterclockwise with respect to outer frame 100.

[0056] The visor holder 300 may be coupled to the outer frame 100. The visor holder 300 is rotatably coupled to the outer frame 100 in a direction toward the outer frame 100 or in a direction opposite to the outer frame 100. In this case, the rotation of the visor holder 300 may be performed in conjunction with the rotation of the visor 200, and a detailed description thereof will be provided below.

[0057] In the illustrated embodiment, the outer frame 100 includes a frame opening 110.

[0058] The frame opening 110 communicates with a receiving space (reference numeral not assigned) formed inside the outer frame 100 and an outside.

[0059] The frame opening 110 may be open to or covered by visor 200. That is, in the illustrated embodiment, when the visor 200 is rotated clockwise with respect to the right side, the frame opening 110 may be opened and communicate with an outside.

[0060] Additionally, in the illustrated embodiment, when the visor 200 is rotated counterclockwise with respect to the right side, the frame opening 110 is closed, and communication with the outside is blocked.

[0061] Referring to FIGS. 1 to 4, the head protection device 10 according to an embodiment of the present invention includes a visor 200.

[0062] The visor 200 is rotatably coupled to the outer frame 100 to open or close the frame opening 110. That is, the visor 200 is formed to partially cover the frame opening 110. While driving, the visor 200 closes the frame opening 110 to prevent outside air or foreign substances from flowing into a receiving space (reference numeral not assigned) of the head protection device 10.

[0063] The visor 200 may be made of a lightweight yet highly rigid material. Additionally, the visor 200 may be formed of a light-transmissive material. In one embodiment, the visor 200 may be formed of a synthetic resin material such as reinforced plastic.

[0064] The visor 200 is coupled to the visor holder 300. Specifically, the visor 200 seated on the outer frame 100 may be pressed and supported by the visor holder 300 in a direction toward the outer frame 100.

[0065] The visor 200 is rotatably coupled to the outer frame 100. In the illustrated embodiment, with respect to the right side, the visor 200 may be rotated clockwise and moved upward. In the above state, the frame opening 110 may be opened.

[0066] In the illustrated embodiment, with respect to the right side, the visor 200 may be rotated counterclockwise and moved downward. In the above state, the visor 200 may close the frame opening 110.

[0067] In the embodiment shown in FIGS. 3 to 5, the visor 200 includes a pressing edge 210, a limiting protrusion 220 and a visor coupler 230.

[0068] The pressing edge 210 forms a portion of a corner of visor 200. The pressing edge 210 is defined as a portion of a corner facing the visor holder 300 coupled to the outer frame 100. In the illustrated embodiment, the pressing edge 210 forms a portion of the lower edge corner of the back side of the visor 200.

[0069] When the visor 200 is moved in a direction to close the frame opening 110, which is a counterclockwise direction in the illustrated embodiment, the pressing edge 210 is received in a visor receiving space 312. In this case, the pressing edge 210 presses a pressing plate 323 located in the visor receiving space 312.

[0070] Accordingly, the visor holder 300 may be rotated in a direction toward the outer frame 100, to be able to press the visor 200. A detailed description thereof will be provided below.

[0071] A plurality of pressing edges 210 may be defined. The plurality of pressing edges 210 may be located at each end of the visor 200 in an extension direction. In the illustrated embodiment, the pressing edge 210 forms a left back lower corner and a right back lower corner of visor 200, respectively.

[0072] The limiting protrusion 220 is located adjacent to the pressing edge 210.

[0073] The limiting protrusion 220 protrudes inward from the visor 200. When the visor 200 is received in the visor receiving space 312, the limiting protrusion 220 may be fitted into the coupling groove 315 provided in the visor holder 300. Accordingly, arbitrary separation of the visor 200 and the visor holder 300 may be prevented.

[0074] Specifically, when the visor 200 is coupled to the visor holder 300, the visor 200 is elastically deformed in a radially inward direction, that is, in a direction toward the outer frame 100. At the same time, the limiting protrusion 220 is fitted into the coupling groove 315, thereby preventing the visor 200 from being arbitrarily separated from the visor holder 300 without the application of an external force.

[0075] The visor coupler 230 surrounds the pressing edge 210 and is coupled to the visor 200.

[0076] Meanwhile, in one embodiment, the visor coupler 230 may rotatably couple a main visor (reference numeral not assigned) and a sub-visor (reference numeral not assigned).

[0077] With the visor 200 seated on the outer frame 100, the visor coupler 230 may be positioned between the outer frame 100 and the visor holder 300. In other words, the visor coupler 230 may be positioned in the visor receiving space 312 together with the pressing edge 210.

[0078] A plurality of visor couplers 230 may be provided. The plurality of visor couplers 230 may be disposed at different positions. As an example, two visor couplers 230 may be provided and coupled to the pressing edges 210 located on the left and right sides of the visor 200, respectively.

[0079] Referring again to FIGS. 1 to 4, the head protection device 10 according to an embodiment of the present invention includes a visor holder 300.

[0080] The visor holder 300 is rotated to press the visor 200 seated on the outer frame 100 inward. In this case, the visor holder 300 may be configured to press the visor 200 as it is pressed and rotated by the visor 200.

[0081] Therefore, considering that the visor 200 is seated on the outer frame 100 in a normal driving environment, the above configuration minimizes the area or volume of the visor holder 300 protruding outward from the outer frame 100 while driving. Accordingly, air resistance applied to the head protection device 10 while driving may be minimized.

[0082] The visor holder 300 may be coupled to the outer frame 100. In the illustrated embodiment, the outer frame 100 extends in a sphere shape while covering a receiving space (reference numeral not assigned) formed therein, and an open frame opening 110 is formed on the front side. The visor holder 300 may be disposed at a front end of the outer frame 100 covering the frame opening 110.

[0083] The visor holder 300 is rotatably coupled to the outer frame 100. That is, the visor holder 300 may be rotated in a direction toward the outer frame 100 and in a direction opposite to the outer frame 100.

[0084] An external force for moving the visor holder 300 in a direction toward the outer frame 100 may be applied by pressing the seated visor 200. An external force for moving the visor holder 300 in a direction opposite to the outer frame 100 may be applied by an elastic member 314 provided on the visor holder 300.

[0085] A plurality of visor holders 300 may be provided. The plurality of visor holders 300 may be arranged at different positions to press the seated visor 200 in a direction toward the outer frame 100, that is, toward an inside. In the illustrated embodiment, two visor holders 300 are provided and disposed at a left front end and a right front end of the outer frame 100, respectively.

[0086] In this case, it will be understood that the visor holder 300 positioned on the left side presses the visor 200 towards the right side, and the visor holder 300 positioned on the right side presses the visor 200 towards the left side.

[0087] The visor holder 300 is coupled to the visor coupler 230. Specifically, a visor support 310 and a visor pressing part 320 provided in the visor holder 300 are disposed to face each other with the visor coupler 230 interposed therebetween. In other words, the visor coupler 230 is positioned between the visor support 310 and the visor pressing part 320.

[0088] Accordingly, it can be said that the visor holder 300 also presses the visor coupler 230 provided on the visor 200 in a direction toward the outer frame 100.

[0089] In the embodiment shown in FIGS. 6 to 8, the visor holder 300 includes a visor support 310 and a visor pressing part 320.

[0090] The visor support 310 supports and receives the visor 200 seated on the outer frame 100. Specifically, the visor support 310 supports and receives the pressing edge 210 formed on the visor 200 and the visor coupler 230 coupled thereto.

[0091] The visor support 310 is located at each end in an extension direction of the outer frame 100, which is at the front left end and at the front right end in the illustrated embodiment, respectively.

[0092] The visor support 310 is coupled to the visor pressing part 320. Specifically, the visor pressing part 320 is rotatably coupled to the visor support 310. The visor support 310 rotatably supports the visor pressing part 320.

[0093] The visor support 310 extends along a direction in which the outer frame 100 extends. In the illustrated embodiment, the visor support 310 is formed to extend obliquely toward a lower side at the front and an upper side at the back. In this case, the inclination of the visor support 310 is preferably determined according to the inclination of the pressing edge 210 of the visor 200.

[0094] In the illustrated embodiment, the visor support 310 includes a support protrusion 311, a visor receiving space 312, a receiving groove 313, an elastic member 314 and a coupling groove 315.

[0095] The support protrusion 311 supports one corner facing the outer frame 100 among the corners of the visor 200 seated on the outer frame 100 from an outside. In this case, as the pressing edge 210 of the visor 200 is received in the visor receiving space 312, it will be understood that the one corner of the visor 200 supported by the support protrusion 311 is a corner that is adjacent to the pressing edge 210, which is positioned relatively on an upper side.

[0096] The support protrusion 311 is formed to have a predetermined surface area. Accordingly, the support protrusion 311 partially covers an outer side surface of the visor 200 seated on the outer frame 100, thereby preventing the visor 200 from being released to the outside.

[0097] The support protrusion 311 is disposed to face the outer frame 100 with the visor 200 seated on the outer frame 100 interposed therebetween. Accordingly, it will be understood that while the visor 200 is seated on the outer frame 100, the outer frame 100, the visor 200 and the support protrusion 311 are arranged sequentially from the inside to the outside.

[0098] The support protrusion 311 is spaced apart from a surface of the outer frame 100 to form a space therebetween, and the visor 200 may be received in the space. The space communicates with the visor receiving space 312.

[0099] The support protrusion 311 is located at one end in an extension direction of the visor support 310, which is at the upper end in the illustrated embodiment. Accordingly, it can be said that the support protrusion 311 supports an upper side of the pressing edge 210 of the visor 200 seated on the outer frame 100.

[0100] The visor receiving space 312 receives the visor 200 seated on the outer frame 100, and specifically, the pressing edge 210 of the visor 200 or the visor coupler 230 coupled thereto. Additionally, the visor pressing part 320 is rotatably received in the visor receiving space 312.

[0101] In this case, the visor pressing part 320 is disposed to cover the visor receiving space 312, and the pressing edge 210 inserted into the visor receiving space 312 may be configured to press the visor pressing part 320, specifically, the pressing plate 323. Additionally, the pressing edge 210 inserted into the visor receiving space 312 may be pressed by the visor pressing part 320. A detailed description thereof will be provided below.

[0102] The visor receiving space 312 is formed inside the visor support 310. A portion of the outer side of the visor receiving space 312 is formed to be open such that the visor 200 may be withdrawn and inserted. In the illustrated embodiment, the front side of the visor receiving space 312 is open such that the pressing edge 210 of the visor 200 may be inserted into the visor receiving space 312 in a withdrawable manner.

[0103] Another portion outside the visor receiving space 312 is also formed to be open. The visor pressing part 320 may be rotatably coupled to the visor support 310 in the other open portion. In the illustrated embodiment, the outer side (i.e., right side) of the visor receiving space 312 in the width direction is formed to be open.

[0104] The visor receiving space 312 may be formed in a shape corresponding to the shape of the visor support 310. In the illustrated embodiment, the visor receiving space 312 is formed to extend obliquely downward on a lower side of the front and an upper side of the back.

[0105] The visor receiving space 312 communicates with the receiving groove 313.

[0106] The receiving groove 313 is formed to be recessed on one surface of the visor support 310 covering the visor receiving space 312, which is a lower side surface in the illustrated embodiment. The receiving groove 313 rotatably receives the visor pressing part 320. Inside the receiving groove 313, a member (reference numeral not assigned) may be provided to rotatably support a rotating protrusion 324 provided on the visor pressing part 320.

[0107] The receiving groove 313 may be of any shape that is capable of rotatably supporting the visor pressing part 320. In the illustrated embodiment, the receiving groove 313 has a square cross-section, and is formed as a space of a square pillar which is formed to be recessed in a thickness direction of the visor support 310.

[0108] A plurality of receiving grooves 313 may be provided. The plurality of receiving grooves 313 may be arranged to be spaced apart from each other along a direction in which the visor support 310 or the visor receiving space 312 extends. In the illustrated embodiment, two receiving grooves 313 are provided. Any one receiving groove 313 is located toward an upper back side, and the other receiving groove 313 is located toward a lower front side.

[0109] The number and arrangement method of the receiving grooves 313 may change depending on a position of the rotating protrusion 324 provided on the visor pressing part 320.

[0110] In this case, an elastic member 314 that elastically supports the visor pressing part 320 may be accommodated in any one or more of the plurality of receiving grooves 313. In the illustrated embodiment, the elastic member 314 is received in the receiving groove 313 located on the lower front side.

[0111] The elastic member 314 is pressed by the visor 200 and applies a restoring force in an outward direction to the rotated visor pressing part 320. The elastic member 314 is received in the receiving groove 313, and elastically supports the visor pressing part 320 that is rotatably coupled to the receiving groove 313.

[0112] The elastic member 314 may be deformed in shape by an external force, store a restoring force, and be provided in any form capable of transmitting the stored restoring force to another member. In the illustrated embodiment, the elastic member 314 is provided in the form of a torsion spring.

[0113] The elastic member 314 may be received in any one or more of the plurality of receiving grooves 313. In the illustrated embodiment, the elastic member 314 is received in the receiving groove 313 located on the lower side of the front. Alternatively, a plurality of elastic members 314 may be provided, and may be respectively received in a plurality of receiving grooves 313.

[0114] The elastic member 314 is coupled to the rotating protrusion 324 of the visor pressing part 320. The elastic member 314 may be in contact with the pressing plate 323 of the visor pressing part 320 and may be pressed by or press the pressing plate 323.

[0115] A detailed description of a process in which the elastic member 314 is pressed to store a restoring force and transmitting the stored restoring force to the visor pressing part 320 will be described below.

[0116] The coupling groove 315 is a portion where the visor 200 is coupled to the visor holder 300 such that it may be removed. The coupling groove 315 is located on one side facing the visor 200 among corners in an extension direction of the visor support 310, which is at a front side end in the illustrated embodiment.

[0117] The coupling groove 315 may be formed as a space into which the limiting protrusion 220 of the visor 200 is coupled in a withdrawable manner. In one embodiment, the limiting protrusion 220 may be fitted into the coupling groove 315. In the above embodiment, the limiting protrusion 220 coupled to the coupling groove 315 is not arbitrarily withdrawn from the coupling groove 315, unless an external force having a predetermined size and direction is applied.

[0118] Accordingly, the coupled state of the coupling groove 315 and the limiting protrusion 220 is maintained stably, and as a result, the coupled state between the visor 200 and the visor holder 300 may be maintained stably.

[0119] The coupling groove 315 may be formed in any shape that may receive the limiting protrusion 220 in a withdrawable manner. In the illustrated embodiment, the coupling groove 315 is formed as a recessed space in the visor support 310.

[0120] The visor pressing part 320 is pressed and rotated by the visor 200 seated on the outer frame 100 so as to support the visor 200 from the outside. When the visor 200 is rotated and the seated state is released, the visor pressing part 320 is rotated by the restoring force applied by the elastic member 314 to release the visor 200.

[0121] In other words, the visor pressing part 320 is pressed by one side corner of the visor 200, that is, the pressing edge 210, and presses the other side of the visor 200, that is, the left or right side of the visor 200, toward the outer frame 100.

[0122] The visor pressing part 320 is located at each end in an extension direction of the outer frame 100, which is a front left end and a front right end in the illustrated embodiment, respectively. The visor pressing part 320 is disposed to cover the visor support 310 and the visor coupler 230 from the outside.

[0123] The visor pressing part 320 is coupled to the visor support 310. The visor pressing part 320 is coupled to the visor support 310 so as to be rotatable in a direction opposite to the outer frame 100 or the visor support 310.

[0124] The visor pressing part 320 is formed to extend along a direction in which the outer frame 100 extends. In the illustrated embodiment, the visor pressing part 320 is formed to extend obliquely toward a lower side at the front and an upper side at the back. In this case, the inclination of the visor pressing part 320 is preferably determined according to the inclination of the pressing edge 210 of the visor 200. In other words, it will be understood that the extension direction of the visor pressing part 320 is the same as the extension direction of the visor support 310.

[0125] The visor pressing part 320 is partially received in the visor receiving space 312. The visor pressing part 320 is disposed to partially cover the visor receiving space 312 such that the pressing edge 210 of the visor 200 received in the visor receiving space 312 may be in contact with the visor pressing part 320. Accordingly, the pressing plate 323 of the visor pressing part 320 may be pressed by the pressing edge 210.

[0126] The visor pressing part 320 is coupled to the elastic member 314. The visor pressing part 320 may be rotated in a direction opposite to the outer frame 100 by the restoring force applied by the elastic member 314.

[0127] In the embodiment shown in FIGS. 6 to 8, the visor pressing part 320 includes a pressing body 321, a coupling rib 322, a pressing plate 323 and a rotating protrusion 324.

[0128] The pressing body 321 forms a body of the visor pressing part 320. The pressing body 321 extends obliquely in a direction in which the visor support 310 extends, which is toward a lower side at the front and an upper side at the back in the illustrated embodiment.

[0129] The pressing body 321 is disposed outside the visor support 310 and the visor coupler 230. The pressing body 321 is disposed to face the visor support 310 with the visor coupler 230 interposed therebetween.

[0130] The pressing body 321 is disposed to cover a portion of the visor 200 received in the visor receiving space 312 from the outside. When the pressing edge 210 of the visor 200 presses the pressing plate 323, the pressing body 321 is configured to be rotated toward the outer frame 100 or the received visor 200, so as to press the visor 200 inward.

[0131] Accordingly, a state in which the visor 200 is seated on the outer frame 100 may be stably maintained.

[0132] The pressing body 321 may have any shape that can press and support the visor 200 inward. In the illustrated embodiment, the pressing body 321 is formed in a plate shape with a frame opening formed on one side facing the outer frame 100.

[0133] The coupling rib 322 is a portion where the visor pressing part 320 is coupled to the visor support 310. The coupling rib 322 extends from the pressing body 321 toward the visor support 310.

[0134] In the illustrated embodiment, the coupling rib 322 extends a predetermined length from one corner of the pressing body 321 facing the visor support 310, that is, a back side corner. The coupling rib 322 is rotatably received in the receiving groove 313.

[0135] The coupling rib 322 may be of any shape that can be rotatably received in the receiving groove 313. In the illustrated embodiment, the coupling rib 322 has a rectangular plate shape extending in a direction toward the visor support 310 (i.e., longitudinal direction) and in a direction in which the pressing body 321 extends (i.e., width direction).

[0136] A plurality of coupling ribs 322 may be provided. The plurality of coupling ribs 322 may be arranged to be spaced apart from each other along the extension direction of the pressing body 321. In the illustrated embodiment, two coupling ribs 322 are provided and arranged to be spaced apart from each other along the extension direction of the pressing body 321.

[0137] The number and arrangement method of the coupling ribs 322 may vary depending on the number and arrangement method of the receiving grooves 313.

[0138] The coupling rib 322 is continuous with the pressing plate 323.

[0139] The pressing plate 323 is pressed by the pressing edge 210 and rotated in a direction toward the visor support 310. Accordingly, the visor pressing part 320 may be rotated in a direction toward the outer frame 100, so as to press and support the visor 200 received in the visor receiving space 312. To this end, the pressing plate 323 may be in contact with the elastic member 314.

[0140] When the visor 200 is rotated and the pressing edge 210 releases the pressing plate 323, the pressing plate 323 rotates in a direction opposite to the visor support 310 by the restoring force applied by the elastic member 314. Accordingly, the visor pressing part 320 may be rotated in a direction opposite to the outer frame 100.

[0141] The pressing plate 323 is continuous with the pressing body 321. The pressing plate 323 is formed to extend toward the outer frame 100 from one corner of the pressure body 321 facing the visor support 310, which is a back side corner in the illustrated embodiment.

[0142] The pressing plate 323 is continuous with the coupling rib 322. As described above, a plurality of coupling ribs 322 may be provided and arranged to be spaced apart along a direction in which the pressing body 321 extends. In the illustrated embodiment, the pressing plate 323 is continuous with the engaging rib 322 located on the front side.

[0143] In this case, the pressing plate 323 may extend at a predetermined angle with the coupling rib 322. That is, the pressing plate 323 may extend toward the outer frame 100 to cover the receiving groove 313. In one embodiment, the pressing plate 323 may extend perpendicular to the coupling rib 322.

[0144] In an embodiment not shown, a plurality of pressing plates 323 may be provided. In the above embodiment, the pressing plate 323 may each be continuous with a plurality of coupling ribs 322. In the above embodiment, an elastic member 314 may be provided in each of the plurality of receiving grooves 313 to apply a restoring force to each pressing plate 323.

[0145] Rotating protrusions 324 are provided at each end in a width direction of the coupling rib 322.

[0146] The rotating protrusion 324 is a portion of the visor pressing part 320 that is rotatably coupled to the visor supporting portion 310. The rotating protrusion 324 is rotatably received in the receiving groove 313. The rotating protrusion 324 is rotatably supported by a portion of the visor support 310 surrounding the receiving groove 313.

[0147] The rotating protrusion 324 is continuous with the coupling rib 322. The rotating protrusion 324 extends from a widthwise end of the coupling rib 322 in the longitudinal direction of the pressing body 321. In the illustrated embodiment, the rotating protrusion 324 extends downward at the front and upward at the back.

[0148] The rotating protrusion 324 may be of any shape capable of rotatably supporting the visor pressing part 320. In the illustrated embodiment, the rotating protrusion 324 has a circular cross-section and has a cylindrical shape extending in a direction in which the pressing body 321 extends.

[0149] In an embodiment in which the elastic member 314 is provided as a torsion spring, the rotating protrusion 324 may be inserted into a hollow formed inside the elastic member 314.

[0150] A plurality of rotating protrusions 324 may be provided. The plurality of rotating protrusions 324 may be disposed at each end of the coupling rib 322 in the width direction. In the illustrated embodiment, two rotating protrusions 324 are provided and are located at a front side end and a back side end of the coupling rib 322, respectively.

[0151] The rotating protrusions 324 may be provided in a plurality of pairs. A plurality of pairs of rotating protrusions 324 may be provided on each of the plurality of coupling ribs 322. In the illustrated embodiment, two pairs of rotating protrusions 324 are provided and are respectively disposed at ends of the two coupling ribs 322 in the width direction.

[0152] A receiving space 325 is a space formed on one side of the pressing body 321 facing the outer frame 100. The receiving space 325 has one side facing the outer frame 100 open, and at least partially receives the visor coupler 230.

[0153] The receiving space 325 may be formed in a shape corresponding to the shape of the pressing body 321. In the illustrated embodiment, the receiving space 325 is formed to extend downward on a lower side at the front and an upper side at the back. The receiving space 325 may be of any shape capable of at least partially receiving visor coupler 230.

[0154] By the receiving space 325, the visor pressing part 320 may be arranged to overlap the visor coupler 230. Accordingly, the visor pressing part 320 does not protrude to the outside of the outer frame 100.

[0155] The head protection device 10 according to an embodiment of the present invention includes a visor holder 300 for maintaining the position of the visor 200 seated on the outer frame 100 to cover the frame opening 110. The visor holder 300 is configured to press the visor 200 seated on the outer frame 100 in a direction toward the outer frame 100, which is toward an inner side in the illustrated embodiment.

[0156] In this case, the visor holder 300 is configured to press the seated visor 200 in a direction toward the outer frame 100 such that the visor 200 is not arbitrarily separated from the outer frame 100.

[0157] Additionally, the visor holder 300 is pressed by the visor 200 seated on the outer frame 100 and rotates in a direction toward the outer frame 100. Accordingly, when the visor 200 is seated on the outer frame 100, the area of the visor holder 300 exposed to the outside of the outer frame 100 may be minimized.

[0158] As a result, the visor holder 300 may stably support the visor 200 seated on the outer frame 100. At the same time, since the visor holder 300 is not exposed to the outside of the outer frame 100, driving resistance generated during driving may be minimized. Furthermore, the visor holder 300 may form a sense of design unity with the outer frame 100.

[0159] Meanwhile, when the visor 200 is spaced apart from the outer frame 100, that is, when the frame opening 110 is rotated to open, the visor pressing part 320 rotates outward by the restoring force applied by the elastic member 314. That is, the visor holder 300 may be rotated by rotation of the visor 200 without separate manipulation.

[0160] Hereinafter, the operation process of a head protection device 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. 9 and 10.

[0161] Referring to FIG. 9, the head protection device 10 is shown in a state where the visor 200 is located at a first position (P1).

[0162] In the above state, the visor 200 is partially received in the visor receiving space 312. Specifically, the pressing edge 210 of the visor 200 presses the pressing plate 323 of the visor holder 300 and is received in the visor receiving space 312.

[0163] Accordingly, the visor pressing part 320 is rotated in a direction toward the outer frame 100 to press the visor 200 received in the visor receiving space 312 from the outside to the inside.

[0164] In the above state, the visor coupler 230 is also received in the visor receiving space 312. Accordingly, the visor 200, the visor coupler 230 and the visor pressing part 320 are positioned sequentially in a direction from the inside to the outside of the outer frame 100.

[0165] As the pressing plate 323 of the visor pressing part 320 is pressed by the pressing edge 210 and rotated in a direction toward the outer frame 100, the area of the visor pressing part 320 exposed to the outside of the outer frame 100 is minimized.

[0166] As described above, in normal driving situations, the visor 200 is received in the visor receiving space 312 and is seated on the outer frame 100. Accordingly, deterioration in driving performance caused by the visor holder 300 during driving may be minimized, and noise generated by the flow of outside air may be minimized.

[0167] Furthermore, in the event of an accident, the phenomenon of getting caught by the visor holder 300 may be minimized, thereby minimizing damage from secondary accidents.

[0168] Meanwhile, as the visor 200 is located at the first position (P1) and the visor pressing part 320 rotates in a direction toward the outer frame 100, the elastic member 314 is compressed and stores a restoring force.

[0169] In this case, as the limiting protrusion 220 of the visor coupler 230 is fitted into the coupling groove 315, the elastic member 314 is maintained in a compressed state. That is, while the visor 200 is maintained at the first position (P1), the elastic member 314 stores a restoring force but does not transmit the stored restoring force to other members.

[0170] Referring to FIG. 10, the head protection device 10 is shown in a state where the visor 200 is located at a second position (P2).

[0171] In the above state, the visor 200 is pulled out from the visor receiving space 312. Accordingly, the elastic member 314 restrained by the visor 200 and the pressing plate 323 is released, returns to an initial shape and transmits the stored restoring force to the visor pressing part 320.

[0172] As described above, the direction of a restoring force stored by the elastic member 314 is a direction opposite to the outer frame 100, that is, a direction toward the outside. Accordingly, the visor pressing part 320 is rotated in a direction opposite to the outer frame 100, that is, toward the outside, due to the restoring force.

[0173] Meanwhile, in order for the visor 200 received in the visor receiving space 312 to rotate, the coupled state of the limiting protrusion 220 and the coupling groove 315 must be released by an external force. As described above, since the limiting protrusion 220 is fitted into the coupling groove 315, an external force must be applied to the visor 200 in order to separate the limiting protrusion 220 from the coupling groove 315.

[0174] Therefore, the visor 200 does not arbitrarily escape from the visor receiving space 312 unless an external force is applied. Accordingly, the visor pressing part 320 pressed by the pressing edge 210 of the visor 200 is also not arbitrarily rotated to the outside of the outer frame 100 unless an external force is applied.

[0175] Therefore, after the visor 200 is pressed outward by a wearer, the coupled state of the limiting protrusion 220 and the engaging groove 315 is released, and the visor 200 may be rotated only after the visor pressing part 320 has been rotated to protrude with respect to the outer frame 100. Considering that the above situation is generally a stationary situation rather than a driving situation, it will be understood that the deterioration of driving performance or the generation of driving noise caused by the visor holder 300 may be minimized.

[0176] As described above, the head protection device 10 according to an embodiment of the present invention includes a visor 200 rotatably coupled to the outer frame 100 and a visor holder 300 provided on an outer frame 100 to receive the visor 200.

[0177] When the visor 200 is elastically deformed, rotated and seated on the outer frame 100, the visor holder 300 is pressed by the visor 200 and rotates in a direction toward the outer frame 100. The rotated visor holder 300 presses the visor 200 in a direction toward the outer frame 100 such that the visor 200 may be stably maintained on the outer frame 100.

[0178] In addition, as the pressing plate 323 of the visor pressing part 320 of the visor holder 300 is pressed by the visor 200 and rotated in a direction toward the outer frame 100, the area protruding outward from the outer frame 100 is also minimized.

[0179] Accordingly, when the wearer of the head protection device 10 drives, air resistance caused by the visor holder 300 is minimized, and deterioration in driving performance may also be minimized.

[0180] Additionally, the visor 200 is provided with a limiting protrusion 220. When the visor 200 is rotated and received in the visor receiving space 312, the limiting protrusion 220 is fitted into the coupling groove 315 of the visor holder 300 such that the visor 200 and the visor holder 300 are coupled to each other. Unless an external force is applied to the visor 200 and the coupling is released, the visor 200 and the visor holder 300 are not separated arbitrarily.

[0181] Accordingly, a state in which the visor 200 is seated on the outer frame 100 may be stably maintained.

[0182] As the visor holder 300 presses the visor 200 in a direction toward the outer frame 100, that is, inward, the visor 200 remains closed. Accordingly, when an external force is applied to the visor 200, the visor 200 may be moved toward the outside of the outer frame 100 rather than the inside.

[0183] That is, when an external force is applied to the visor 200, the visor support 310 may prevent the visor 200 from flowing into the frame opening 110. Accordingly, safety accidents caused by elastic deformation of the visor 200 may be prevented.

[0184] Additionally, when the visor 200 is rotated and seated on the outer frame 100, the pressing edge 210 presses the pressing plate 323 of the visor pressing part 320. Accordingly, the visor pressing part 320 is moved in a direction toward the outer frame 100, that is, inward, such that the area protruding to the outside of the outer frame 100 may be minimized.

[0185] In this case, the visor pressing part 320 rotates in a direction toward the outer frame 100 and presses the elastic member 314. Accordingly, the elastic member 314 is deformed in shape and stores a restoring force. The coupled state of the visor 200 and the visor holder 300 is maintained by coupling the above-described limiting protrusion 220 and the coupling groove 315, and the elastic member 314 is maintained in a deformed state.

[0186] When an external force is applied to the visor 200 and the frame opening 110 is rotated to open, the elastic member 314 and the pressing plate 323 are released from the pressing edge 210. Accordingly, the elastic member 314 is restored to an original shape and transmits the stored restoring force to the visor pressing part 320. Accordingly, the visor pressing part 320 may be rotated to the outside of the outer frame 100 by the restoring force applied by the elastic member 314 without any additional manipulation.

[0187] Referring to FIGS. 11 to 13, a head protection device 20 according to another embodiment of the present invention is shown.

[0188] The head protection device 20 according to the present embodiment is similar in structure and operating principle when compared to the head protection device 10 described above. However, the head protection device 20 according to the present embodiment includes an additional member for more stably maintaining a state in which the visor 200 is coupled to the visor holder 300.

[0189] Accordingly, the following will describe the head protection device 20 according to the present embodiment, focusing on the differences from the head protection device 10 according to the above-described embodiment.

[0190] In the illustrated embodiment, the head protection device 20 includes an outer frame 100, a visor 200 and a visor holder 300.

[0191] The outer frame 100 provided in the head protection device 20 according to the present embodiment has the same structure and function as the outer frame 100 according to the above-described embodiment. Accordingly, the description of the outer frame 100 according to the present embodiment will be replaced with the description of the outer frame 100 described above.

[0192] The visor 200 is rotatably coupled to the outer frame 100.

[0193] The visor 200 provided in the head protection device 20 according to the present embodiment is similar in structure and function to the visor 200 according to the above-described embodiment. However, the visor 200 according to the present embodiment differs in that a coupler 240 is additionally coupled to the visor holder 300.

[0194] The coupler 240 rotatably couples a main visor (reference numeral not assigned) and a sub-visor (reference numeral not assigned) provided in the visor 200. The coupler 240 functions as an axis for relative rotation of the main visor (reference numeral not assigned) and the sub-visor (reference numeral not assigned).

[0195] The coupler 240 is located adjacent to the limiting protrusion 220 provided on the visor 200. In the embodiment shown in FIG. 13, the coupler 240 is located radially inside the limiting protrusion 220. The coupler 240 may be located at a portion where the pressing edge 210 and the visor coupler 230 are continuous, which is to be biased toward a lower side at the front in the illustrated embodiment.

[0196] The coupler 240 may be positioned to be exposed on one surface among each surface of the visor 200 facing the frame opening 110 of the outer frame 100. In other words, the coupler 240 is located on an inner surface of the visor 200. When the visor 200 is coupled to the visor holder 300, the coupler 240 may be disposed to face a magnetic force applicator 330.

[0197] The coupler 240 is magnetically coupled to the magnetic force applicator 330 provided in the visor holder 300. In other words, the coupler 240 receives a magnetic attractive force generated by the magnetic force applicator 330. Accordingly, the visor 200 coupled with the visor holder 300 receives a force in a direction in which the coupler 240 is directed toward the magnetic force applicator 330.

[0198] As a result, the coupled state of the visor 200 and the visor holder 300 may be maintained stably.

[0199] The coupler 240 may be provided in any shape that can rotatably couple a main visor (reference numeral not assigned) and a sub-visor (reference numeral not assigned). In one embodiment, the coupler 240 may be provided in the form of a screw member.

[0200] Among the portions of the coupler 240, one side facing the magnetic force applicator 330, that is, the inner side portion, may be formed to have a larger surface area than the other portions. Accordingly, the magnetic attraction between the coupler 240 and the magnetic force applicator 330 may be maximized. In an embodiment where the coupler 240 is provided as a screw member, the inner portion may be defined as a screw head.

[0201] The coupler 240 may be formed of any material that can form magnetic attraction with the magnetic force applicator 330. In one embodiment, the coupler 240 may be formed of iron (Fe) or an electrically conductive material including the same, or may be formed in the form of a permanent magnet.

[0202] The visor 200 may be pressed by the visor holder 300 and maintained in a position covering the frame opening 110.

[0203] The visor holder 300 provided in the head protection device 20 according to the present embodiment is similar in structure and function to the visor holder 300 according to the above-described embodiment. However, there are differences in that the visor holder 300 according to the present embodiment is further provided with a magnetic force applicator 330 for applying a magnetic attraction force to the coupler 240, and a member coupling part 316 for supporting the magnetic force applicator 330 is further provided on the visor support 310.

[0204] The member coupling part 316 is provided on the visor support 310 and supports the magnetic force applicator 330. The member coupling part 316 is formed on one side among each side of the visor support 310 facing the frame opening 110, which is on an inner side in the illustrated embodiment.

[0205] The member coupling part 316 may be arranged to overlap the coupling groove 315 in a radial direction. In other words, the member coupling part 316 may be arranged to face the coupling groove 315 with the magnetic force applicator 330 interposed therebetween. Accordingly, the magnetic attraction force generated by the magnetic force applicator 330 may pass through the coupling groove 315 and be applied to the coupler 240.

[0206] The member coupling part 316 may be provided in any shape capable of supporting the magnetic force applicator 330. In the illustrated embodiment, the member coupling part 316 is provided in the form of a bracket with a space formed therein. The space may be in communication with the coupling groove 315. The magnetic force applicator 330 received in the space may be arranged to overlap the coupling groove 315 in the radial direction.

[0207] The magnetic force applicator 330 applies a magnetic attraction force to the coupler 240. Accordingly, the visor 200 may be stably maintained in a position covering the frame opening 110.

[0208] The magnetic force applicator 330 is coupled to the visor support 310. Specifically, the magnetic force applicator 330 is coupled to the member coupling part 316 formed on the inside of the visor support 310. In one embodiment, the magnetic force applicator 330 may be coupled to the member coupling part 316 in a removable manner.

[0209] The magnetic force applicator 330 coupled to the member coupling part 316 may be arranged to face the coupler 240 of the visor 200 with the coupling groove 315 interposed therebetween. The magnetic attraction generated by the magnetic force applicator 330 may be applied to the coupler 240 through the coupling groove 315.

[0210] The magnetic force applicator 330 may be coupled to the member coupling part 316 and may be provided in any form capable of applying a magnetic attraction force to the coupler 240. In one embodiment, the magnetic force applicator 330 may be provided in the form of a permanent magnet. In an embodiment where the coupler 240 is also provided in the form of a permanent magnet, the magnitude of the magnetic force applied between the magnetic force applicator 330 and the coupler 240 may be maximized.

[0211] As the magnetic force applicator 330 applies a magnetic attraction force to the coupler 240, the position of the visor 200 may be maintained stably even if the magnitude of the force with which the visor holder 300 presses the visor 200 is reduced. In addition, as the magnitude of a force with which the visor holder 300 presses the visor 200 is reduced, the visor 200 may be rotated to open the frame opening 110 without additional horizontal force being applied to the visor 200.

[0212] Although the embodiments of the present invention have been described above, the spirit of the present invention is not limited to the embodiments presented in the present specification, and those skilled in the art who understand the spirit of the present invention may easily suggest other embodiments by changing, modifying, deleting or adding components within the scope of the same spirit, but this will also fall within the scope of the present invention.
