FIG. 1 is a perspective view of a multifunctional helmet equipped with all components in accordance with an embodiment of the present disclosure. - As depicted in
FIG. 1 , a multifunctional helmet in accordance with an embodiment of the present disclosure may include amain body 10, achin guard 20, ashield 30 and apeak sun visor 40. - In the multifunctional helmet in accordance with an embodiment of the present disclosure, each of the
chin guard 20, theshield 30, and thepeak sun visor 40 may be connected/disconnected to/from themain body 10.FIG. 1 shows themain body 10 connected to all of thechin guard 20, theshield 30 and thepeak sun visor 40. - To be specific, the
main body 10 may have a facial front opening at its front side and may be formed into a cap to be worn on a helmet wearer's head. Further, themain body 10 may include a part of connectors A configured to connect thechin guard 20 to themain body 10 by coupling both ends of thechin guard 20 to both ends of lower sides. Furthermore, themain body 10 may be provided with at least one of theshield 30 and thepeak sun visor 40 at its both side surfaces and may include a part of rotational connection units B configured to manipulate opening/closing or a degree of rotation of theshield 30 or thepeak sun visor 40. - The
chin guard 20 may be configured to protect a chin of the helmet wearer by covering a lower side of the opening of themain body 10. Thechin guard 20 may include a part of the connectors A capable of connecting/disconnecting thechin guard 20 to/from themain body 10, and thechin guard 20 may be connected to themain body 10 by the connectors A. - The
shield 30 may be configured to obtain a front view despite wind introduced through the front and prevent difficulty in breathing while the motorcycle moves forwards by opening/closing the facial front opening of themain body 10. Theshield 30, of which extended side surfaces may be coupled to both side surfaces of themain body 10, may include a part of the rotational connection units B capable of opening/closing theshield 30 from a front top of themain body 10 in up and down directions (i.e. Y-axis direction) and theshield 30 may be connected to themain body 10 by the rotational connection units B. - The
peak sun visor 40 may be connected to a top of themain body 10 and configured to protect eyes of the helmet wearer from light while the motorcycle moves forwards. Thepeak sun visor 40, of which extended side surfaces may be coupled to both side surfaces of themain body 10, may include a part of the rotational connection units B capable of manipulating a degree of rotation of thepeak sun visor 40 from the front top of themain body 10 in the up and down directions (i.e. Y-axis direction) and thepeak sun visor 40 may be connected to themain body 10 by the rotational connection units B. - There will be explained a configuration, a coupling method, a method of opening/closing, a method of rotation of the connectors A of the
chin guard 20 and the rotational connection units B of theshield 30 and thepeak sun visor 40 in detail with reference toFIGS. 2 to 4 . -
FIG. 2 is an exploded perspective view of a multifunctional helmet in accordance with the embodiment of the present disclosure. -
FIG. 3 is a cross-sectional view for explaining a connector of a chin guard in accordance with the embodiment of the present disclosure, andFIG. 4 is an exploded perspective view for explaining a rotational connection unit of a shield or a peak sun visor in accordance with the embodiment of the present disclosure. - As depicted in
FIG. 2 , in the multifunctional helmet in accordance with the embodiment of the present disclosure, thechin guard 20, theshield 30 and thepeak sun visor 40 may be configured to be connected/disconnected to/from themain body 10. - Referring to
FIGS. 2 , 3A and 3B, the connectors A of thechin guard 20 will be explained. - The connectors A may include first connectors A-1 installed at both lower ends of the side surfaces of the
main body 10 and second connectors A-2 installed at both ends of thechin guard 20. At least a part of the second connectors A-2 may be inserted into the first connectors A-1, so that thechin guard 20 may be connected to themain body 10. - To be specific, the first connectors A-1 may include a plate-shaped
outer base member 50 positioned at an outside of themain body 10 and a plate-shapedinner base member 51 positioned at an inside of themain body 10. Theouter base member 50 and theinner base member 51 may be connected to themain body 10 by at least one connecting member. When theouter base member 50 and theinner base member 51 are connected to each other, an inner space may be formed there between. - In a partial outside surface of the
outer base member 50, an intagliated groove may be formed in a direction to be in contact with a lower surface of themain body 10, and a difference in a height may be made between an outside surface of themain body 10 and the partial outside surface of theouter base member 50 by the intagliated groove. In themain body 10's lower surface in contact with the intagliated groove, there may be formed afixing opening 53 into which a part of the second connector A-2 may be inserted for fixing a position.FIG. 2 shows that in the first connector A-1 in accordance with the embodiment of the present disclosure, the intagliated groove is formed into a slanting line starting from the front of themain body 10 toward the back of themain body 10. Since the intagliated groove is formed into a slanting line, thechin guard 20 can be easily coupled to themain body 10 along a direction of the chin of the helmet wearer. - In a partial lower surface formed by connecting the
outer base member 50 and theinner base member 51, there may be formed acoupling opening 54 into which a part of the second connector A-2 may be inserted for coupling. In an inside surface of theinner base member 51, a lockingprotrusion 55, by which a part of the second connector A-2 inserted into the lockingprotrusion 55 may maintain them as being coupled, may be protruded. AlthoughFIG. 2 shows that the lockingprotrusion 55 is formed in the inside surface of theinner base member 51, the lockingprotrusion 55 may be formed in an inside surface of theouter base member 50. Since the lockingprotrusion 55 is formed in the first connector A-1 of themain body 10, when the connector A break down due to damage to the lockingprotrusion 55, it may be possible to fix the connector A simply by replacing a part of the first connector A-1. - The second connectors A-2 may include an
insertion base member 56, acoupling control member 57, a manipulatingprotrusion 58, a fixingwing 59 and acoupling loop 60. - To be specific, the plate-shaped
insertion base member 56 is positioned at both ends inside thechin guard 20. Theinsertion base member 56 may be connected to thechin guard 20 by at least one connecting member, and when theinsertion base member 56 is connected to thechin guard 20, an inner space may be formed therebetween. - At a side surface of the inner space (i.e. inside surface) of the
insertion base member 56, a rotation shaft is installed, and thecoupling loop 60 inserted into the first connector A-1 may be fixed to the rotation shaft so as to be rotated. - The
coupling control member 57 may be exposed to an outside surface of thechin guard 20 and may be moved in a transversal direction (i.e. X-axis direction), and the manipulatingprotrusion 58 may be protruded toward the side surface of the inner space (i.e. inside surface) of thechin guard 20. - The manipulating
protrusion 58 may be formed at a position in contact with an end of thecoupling loop 60, and as the manipulatingprotrusion 58 moves in the transversal direction, the end of thecoupling loop 60 may be moved in the same direction as the manipulatingprotrusion 58. Further, as the end of thecoupling loop 60 moves in the transversal direction, the other end of thecoupling loop 60 may be moved in the up and down directions (i.e. Y-axis direction) and the second connector A-2 may be coupled to or decoupled from the first connector A-1. - Hereinafter, a method of the first connector A-1 to the second connector A-2 will be explained in detail with reference to
FIGS. 3A and 3B . -
FIG. 3A is a cross-sectional view for explaining an internal configuration and a coupling status of the first connector A-1 and the second connector A-2, andFIG. 3B is a cross-sectional view for explaining a decoupling status thereof by a coupling control operation of the first connector A-1. - To be specific, as depicted in
FIG. 3A , thecoupling loop 60 may be fixed at arotation shaft 61 installed at theinsertion base member 56 of the second connector A-2. In this case, thecoupling loop 60 may be caught by the lockingprotrusion 55 at a position (hereinafter, referred to as “original position”) at which one end 60-1 of both ends may be not influenced by force caused by manipulation of thecoupling control member 57 and thecoupling loop 60 may be fixed at therotation shaft 61 such that the other end 60-2 may be caught by the manipulatingprotrusion 58 at the original position. - The
coupling loop 60 in accordance with the embodiment of the present disclosure may be formed into a “” shape curved in the middle and thecoupling loop 60 may be opened at a partial outside surface of the curved area at which a fixing groove 60-3 configured to catch an end of anelastic member 62 may be formed. Theelastic member 62 may include a spring or the like and may have elasticity by which theelastic member 62 may be stretched in a direction of force caused by a transversal movement of thecoupling control member 57 and may return to its original position when the force caused by the transversal movement of thecoupling control member 57 is removed. - The end of the
elastic member 62 may be caught by the fixing groove 60-3, and the other end may be extended toward an inside of the curved area and caught by a catch bloc formed in theinsertion base member 56. The other end 60-2 of thecoupling loop 60 may be continuously caught by the manipulatingprotrusion 58 by contractile force in a direction toward the manipulatingprotrusion 58 of theelastic member 62. - In this case, if the end 60-1 of
coupling loop 60 is inserted into thecoupling opening 54 so as to introduce from a lower side of the lockingprotrusion 55 toward the back of themain body 10, the end 60-1 may be rotated in a downward direction (i.e. in a downward direction of the Y-axis) by pushing force of the fixed lockingprotrusion 55 and the other end 60-2 may be rotated in the downward direction accordingly. - If the end 60-1 of the
coupling loop 60 is free from the lockingprotrusion 55 and inserted into the first connector A-1, the end 60-1 may be influenced by restoring force of theelastic member 62 to return to a upward direction (i.e. upward direction of the Y-axis) and the end 60-1 may be caught by the lockingprotrusion 55. As depicted inFIG. 3A , a state in which the end 60-1 of thecoupling loop 60 is caught by the lockingprotrusion 55 may be referred to as a coupled state. - Meanwhile, as depicted in
FIG. 3B , a state in which the end 60-1 of thecoupling loop 60 is rotated in the downward direction of the lockingprotrusion 55 and free from the lockingprotrusion 55 may be referred to as a decoupled state. - To be specific, if the
coupling control member 57 is moved in the transversal direction while the coupling loop is inserted into the first connector A-1, the manipulatingprotrusion 58 may be moved in the transversal direction which is the same direction as thecoupling control member 57. -
FIG. 3B shows that the manipulatingprotrusion 58 may be moved in a right direction and the other end 60-2 of thecoupling loop 60 caught by the manipulatingprotrusion 58 may be applied with pushing force in the right direction. Thus, the other end 60-2 may be pushed in the right direction and rotated in the downward direction (i.e. in the downward direction of the Y-axis) at the same time. - Accordingly, the end 60-1 of the
coupling loop 60 may be rotated in the downward direction of the lockingprotrusion 55 to be in a decoupled state. - As described above, after the
coupling loop 60 of the second connector A-2 is inserted into the first connector A-1, a coupled state may be maintained, so that thechin guard 20 may be connected to themain body 10. Further, if thecoupling loop 60 is in a decoupled state by a transversal movement of thecoupling control member 57 of the second connector A-2, thechin guard 20 may be disconnected from themain body 10. - In this case, the connector A in accordance with the embodiment of the present disclosure may further include the fixing
wing 59 in order to stably fix a coupled position of thechin guard 20. - To be specific, as depicted in
FIG. 2 , the fixingwing 59 may be installed at a partial upper surface of both ends of thechin guard 20 and inserted into the fixingopening 53 formed by the intagliated groove between themain body 10 and the first connector A-1. In this way, the fixingwing 59 may be inserted into the fixingopening 53, so that the coupled position of thechin guard 20 may be stably fixed along a direction of the chin of the helmet wearer. - Hereinafter, the rotational connection unit B of the
shield 30 and thepeak sun visor 40 will be explained with reference toFIGS. 2 and 4 . - The rotational connection unit B of the
shield 30 and thepeak sun visor 40 may include first rotational connection units B-1 installed at both side surfaces of themain body 10, second rotational connection units B-2 installed at both extended side surfaces of thepeak sun visor 40, and third rotational connection units B-3 installed at both ends of extended side surfaces of theshield 30. - The first rotational connection unit B-1 may include a plate-shaped rotational
connection base member 80, a groove-shapedrotation shaft 81,connection grooves 82 formed at corresponding positions in the rotationalconnection base member 80 and in themain body 10, and acoupling fixing member 83. - After the first rotational connection unit B-1 is coupled to at least one of the second rotational connection unit B-2 positioned in the
peak sun visor 40 and the third rotational connection unit B-3 positioned in theshield 30, thecoupling fixing member 83 may be connected to therotation shaft 81, so that theshield 30 and thepeak sun visor 40 may be coupled to themain body 10. - In this case, the
coupling fixing member 83 and therotation shaft 81 may be screw-coupled with each other, and a screw thread of thecoupling fixing member 83 may be formed longer than a plate thickness of each of the extended side surfaces of theshield 30 and thepeak sun visor 40. - To be specific, the
coupling fixing member 83 may be designed to adjust a height to be screw-inserted into therotation shaft 81, and, thus, themain body 10 may be connected to any one or both of theshield 30 and thepeak sun visor 40. That is, a coupled state can be fixed by screwing thecoupling fixing member 83 to therotation shaft 81 as much as any one of theshield 30 and thepeak sun visor 40 is connected to the first rotational connection unit B-1 or by screwing thecoupling fixing member 83 to therotation shaft 81 as much as both theshield 30 and thepeak sun visor 40 are connected to the first rotational connection unit B-1. - Meanwhile, as depicted in
FIG. 4 , in the first rotational connection unit B-1 positioned outside themain body 10, the rotationalconnection base member 80 may be connected (for example, screw-coupled) to themain body 10 by inserting aconnection member 84 into theconnection grooves 82 formed with a certain depth at the corresponding positions in the rotationalconnection base member 80 and in themain body 10. - In the rotational
connection base member 80, adeviation prevention groove 86, an annular-shapedfan receiving unit 89, an annular-shaped insertion guide 88, and alatch stopper 85 may be installed in sequence. - At an outer peripheral surface of the insertion guide 88, a guide passage opened from a center to an outside may be formed. Further, at a partial area of the outer peripheral surface of the insertion guide 88, a guide groove opened to the guide passage and opened from the center to the outside may be formed such that an insertion protrusion, which will be described later, of the
shield 30 may be inserted to the guide groove and rotated along the guide passage.FIG. 4 shows that a first guide groove 87-1, a second guide groove 87-2, and a third guide groove 87-3 may be formed in the outer peripheral surface of the insertion guide 88. - As depicted in
FIG. 4 , the second rotational connection unit B-2 including acoupling hole 41 through which thecoupling fixing member 83 may pass, a deviation prevention protrusion 42 in a shape to be received within thedeviation prevention groove 86, afan protrusion 43 having prominences and depressions contrary to prominences and depressions of thefan receiving unit 89 so as to join together may be positioned at both ends of the extended side surfaces of thepeak sun visor 40. - A width of the
deviation prevention groove 86 may be greater than a width of the deviation prevention protrusion 42, and, thus, if the second rotational connection unit B-2 is coupled to the first rotational connection unit B-1, when thepeak sun visor 40 is rotated around therotation shaft 81, a degree of rotation may be limited to be within a range of the width of thedeviation prevention groove 86. - When the second rotational connection unit B-2 is coupled to the first rotational connection unit B-1, the
fan receiving unit 89 may engage with thefan protrusion 43, and, thus, thepeak sun visor 40 may be intermittently rotated at a certain degree. - That is, if the
peak sun visor 40 is coupled to themain body 10, thepeak sun visor 40 may be rotated within a range of the width of thedeviation prevention groove 86, and, thus, it may be possible to prevent a risk that thepeak sun visor 40 may block the helmet wearer's view. Further, since thepeak sun visor 40 may be intermittently rotated, it may be possible to conveniently adjust an angle of thepeak sun visor 40 depending on an incident angle of light and possible to prevent a risk that thepeak sun visor 40 may slide down. - As depicted in
FIG. 4 , the third rotational connection unit B-3 including an annular-shapedcoupling hole 31 through which thecoupling fixing member 83 may pass and which may have a size sufficient to receive an outer peripheral surface of the insertion guide 88, at least one insertion protrusion 32 protruding from a partial area of an inner peripheral surface of thecoupling hole 31, and a shield protrusion 33 configured to be received in thelatch stopper 85 to be engaged therewith such that a step can be adjusted at the time of opening/closing theshield 30 may be positioned at both ends of the extended side surfaces of theshield 30. -
FIG. 4 shows that a first insertion protrusion 32-1, a second insertion protrusion 32-2, and a third insertion protrusion 32-3 may be formed in the inner peripheral surface of thecoupling hole 31. The first to third insertion protrusion 32-1, 32-2 and 32-3 may be inserted into the first to third guide grooves 87-1, 87-2 and 87-3, respectively and may be rotated along the guide passage of the insertion guide 88. - As depicted in
FIG. 4 , when the first to third insertion protrusion 32-1, 32-2 and 32-3 are inserted into the insertion guide 88, the shield protrusion 33 may be coupled so as to be positioned at a first step of thelatch stopper 85. In this case, if the first to third insertion protrusion 32-1, 32-2 and 32-3 are rotated in a downward direction of a front surface of themain body 10, the shield protrusion 33 may be moved to a second step of thelatch stopper 85. In this way, as the first to third insertion protrusion 32-1, 32-2 and 32-3 are moved in the downward direction, the shield protrusion 33 may be moved to the next step of thelatch stopper 85. Thus, theshield 30 coupled to themain body 10 may be intermittently rotated. - As described above, the
shield 30 may be intermittently rotated in the downward direction, and, thus, it may be possible to prevent a risk that theshield 30 may slide down when theshield 30 is opened at the front opening of themain body 10 and possible to adjust an opening angle of theshield 30. - In the multifunctional helmet in accordance with the embodiment of the present disclosure, if the
main body 10 needs to be connected to both theshield 30 and thepeak sun visor 40, theshield 30 may be coupled to themain body 10 and then thepeak sun visor 40 may be coupled thereto and thecoupling fixing member 83 may pass through thecoupling hole 41 of thepeak sun visor 40 and thecoupling hole 31 of theshield 30 so as to connect to therotation shaft 81 of themain body 10. In this way, both theshield 30 and thepeak sun visor 40 may be connected to themain body 10. - In the multifunctional helmet in accordance with the embodiment of the present disclosure, if the
main body 10 needs to be connected to any one of theshield 30 and thepeak sun visor 40, any one of them may be connected to the main body and then coupling fixingmember 83 may be connected to therotation shaft 81. - In the multifunctional helmet in accordance with the embodiment of the present disclosure, at least one of the
chin guard 20, theshield 30, and thepeak sun visor 40 may be connected to or disconnected from themain body 10. Hereinafter, there will be explained helmet examples in various shapes configured by using such a structure. -

Further,FIG. 9 shows a supermoto type helmet in which themain body 10 may be connected to thechin guard 20 and thepeak sun visor 40. - As described above, the multifunctional helmet in accordance with the embodiment of the present disclosure may be configured to have various shapes other than the shapes shown in
FIGS. 5 to 9 by using the structure in which thechin guard 20, theshield 30 and thepeak sun visor 40 may be connected to and disconnected from themain body 10. - In a multifunctional helmet in accordance with another embodiment of the present disclosure, a
chin guard 20 may be decorated with an ornament which can accentuate characteristics of each helmet. -

FIGS. 10A and 10B show thechin guard 20 which may include all components of thechin guard 20 of the above-described multifunctional helmet in accordance with the embodiment of the present disclosure and may further include theornament 21. - To be specific, as depicted in
FIG. 10A , theornament 21 may be coupled to a front central area of thechin guard 20, and even if theornament 21 is coupled to be higher than a top of thechin guard 20, aventilating opening 22 may be formed such that air can be circulated. - To be specific, as depicted in
FIG. 10B ,connection members 23, 23-1 and 23-3 to be connected to connection grooves 24-1, 24-2 and 24-3, respectively, formed in an outside surface of the front central area of thechin guard 20 may protrude from an inside surface of theornament 21. If theornament 21 is connected to the front central area of thechin guard 20, an intagliated groove may be formed such that air can be introduced through theventilating opening 22. - A multifunctional helmet in accordance with another embodiment of the present disclosure may further include an internal sun visor and an opening/closing apparatus configured to control opening/closing of the internal sun visor.
