[0060] Hereinafter, an accessory and a helmet provided with the accessory according to the present invention will be described with reference to the drawings.

[0061] like Figure 1 to Figure 4 As shown, the accessory 1 is a device mounted on the helmet body 2. The accessory 1 and the helmet body 2 cooperate to form a helmet 3. The helmet body 2 functions as a helmet 3 even without the accessory 1. The accessory 1 adds a chin guard 4 and a shield 5 to the helmet body 2. In addition, the accessory 1 increases the rigidity of the helmet body 2.

[0062] The helmet body 2 has a hemispherical shell 7 and a chin strap 8 combined with the shell 7. The helmet body 2 is a so-called half helmet or half cap-shaped helmet. The shell 7 can be formed of a resin material such as ABS or polycarbonate, or a fiber-reinforced resin. An impact-absorbing pad formed of foamed polystyrene or the like is provided on the inner side of the shell 7. An interior decoration formed of a cushioning material such as polyurethane foam can also be provided on the inner surface of the impact-absorbing pad. The chin strap 8 fixes the helmet body 2 to the user's head by hanging on the wearer's chin. The chin strap 8 can be in a band shape and combined with the shell 7 by rivets or the like. The edge of the front portion of the shell 7 is set as the front edge 7A, the edges of the left and right sides are set as the left and right side edges 7B, and the edge of the rear portion is set as the rear edge 7C.

[0063] The helmet body 2 has a flange portion 11 protruding rearward from the rear edge 7C of the shell 7. The flange portion 11 is formed in an arc shape and extends along the rear edge 7C of the shell 7. In addition, when the helmet body 2 is used alone without attaching the accessory 1, the helmet body 2 can also be used in a reversed manner, and the flange portion 11 is arranged at the front of the helmet body 2.

[0064] The accessory 1 has a base member 13 extending left and right along the outer surface of the rear portion of the housing 7 and coupled to the housing 7. The chin guard 4 is supported by the base member 13. The shield 5 is supported by the chin guard 4. The base member 13, the chin guard 4, and the shield 5 may be formed of a resin material such as ABS or polycarbonate, or a fiber-reinforced resin.

[0065] The base member 13 extends left and right along the upper surface 11A of the flange portion 11. The base member 13 abuts against the rear surface 7D of the housing 7 and the upper surface 11A of the flange portion 11. In addition, the base member 13 extends left and right along the boundary between the rear edge 7C of the housing 7 and the flange portion 11. The upper edge of the base member 13 extends forward and downward from the center in the left-right direction to the end 13A. The lower edge of the base member 13 extends left and right along the upper surface 11A of the flange portion 11. The base member 13 has a width in the up-down direction. The up-down width of the center in the left-right direction of the base member 13 is larger than the up-down width of the end 13A in the left-right direction of the base member 13.

[0066] The base member 13 can be fastened to the housing 7 by a fastening member 15. The fastening member 15 can be, for example, a rivet or a hook and loop fastener. The fastening member can be inserted into a through hole formed in the base member 13 and the housing 7, for example.

[0067] The end portions 13A in the left-right direction of the base member 13 extend to the left and right outer sides than the end portions in the left-right direction of the flange portion 11. The base member 13 has left and right locking portions 21 that are locked with the left and right side edges 7B of the housing 7 at the left and right end portions 13A. The left and right locking portions 21 protrude from the left and right end portions 13A of the base member 13 to the left and right inner sides and abut against the end surfaces of the left and right side edges 7B of the housing 7. The left and right locking portions 21 abut against the end surfaces of the left and right side edges 7B of the housing 7, thereby restricting the upward movement of the base member 13 relative to the housing 7. In addition, the base member 13 abuts against the upper surface 11A of the flange portion 11, thereby restricting the downward movement of the base member 13 relative to the housing 7. That is, the housing 7 is sandwiched between the base member 13 and the left and right locking portions 21 in the vertical direction. The left and right locking portions 21 may be locked to the lower surface of the flange portion 11 in addition to the end surfaces of the left and right side edges 7B of the housing 7.

[0068] The chin guard 4 is mounted on the left and right ends 13A of the base member 13, extends left and right, and protrudes forward. The chin guard 4 is mounted on the base member 13 in a rotatable manner, and the chin guard 4 rotates between a first position below the front edge 7A of the shell 7 and a second position along the front edge 7A of the shell 7. Figure 1 and Figure 2 Indicates the state where the chin guard 4 is located in the first position, Figure 3 and Figure 4 The chin guard 4 is in the second position. The left and right ends 13A of the chin guard 4 are rotatably supported by the left and right ends 13A of the base member 13 via the left and right rotation shafts 18. The left and right rotation shafts extend in the left-right direction and are coaxially arranged.

[0069] The first stoppers 22 are provided at the left and right ends 13A of the base member 13, respectively. The first abutting portions 23 are provided at the left and right ends 13A of the chin guard 4, respectively. Each first stopper 22 is an end surface facing forward and downward. Each first abutting portion 23 is a step portion formed at the lower portion of the chin guard 4. The chin guard 4 is arranged in the first position by abutting each first stopper 22 with the corresponding first abutting portion 23. Each first abutting portion 23 abuts against each first stopper 22 in the front-to-back direction. That is, when the chin guard 4 is located in the first position, the left and right ends 13A of the chin guard 4 abut against the left and right ends 13A of the base member in the front-to-back direction. Thus, the base member 13 and the chin guard 4 cooperate to form a ring structure.

[0070] The left and right ends 13A of the base member 13 are provided with second stoppers 25, respectively. The left and right ends 13A of the chin guard 4 are provided with second contact portions 26, respectively. Each second stopper 25 is a convex portion that protrudes outwardly from the left and right ends 13A of the base member 13, and has an end surface that faces rearward and upward. Each second contact portion 26 is an edge portion of the left and right ends of the chin guard 4. When each second stopper 25 contacts the corresponding second contact portion 26, the chin guard 4 is arranged in the second position.

[0071] The chin guard 4 and the base member 13 may be provided with a locking mechanism for selectively holding the chin guard 4 in the first position and the second position.

[0072] The shield 5 is coupled to the upper portion of the chin guard 4 and extends upward from the chin guard 4. The shield 5 is coupled to the left and right shield retaining portions 28 provided on the upper portion of the chin guard 4. Each shield retaining portion 28 extends upward from the upper edge of the chin guard 4. The left and right ends 13A of the shield 5 can be fastened to the left and right shield retaining portions 28 by fastening members 15 such as rivets. The shield 5 is a transparent plate member having a curved surface convex toward the front. The lower edge of the shield 5 extends left and right along the upper edge of the chin guard 4. The lower edge of the shield 5 can be stopped at the upper edge of the chin guard 4. The shield 5 extends upward from the upper edge of the chin guard 4.

[0073] When the chin guard 4 is in the first position, the upper edge of the shield 5 is along the front edge 7A of the shell 7. Thus, when the chin guard 4 is in the first position, the shield 5 can close the opening 31 defined by the front edge 7A of the shell 7 and the chin guard 4.

[0074] When the chin guard 4 is located at the second position, the shield 5 is disposed above the front edge 7A of the housing 7. The user's face can be opened forward.

[0075] The left and right ends of the chin guard 4 are formed with left and right openings 33 that penetrate in the left and right directions. Through the openings 33, the sound outside the helmet 3 is easily transmitted to the ears of the user of the helmet 3. In addition, the openings 33 also function as ventilation holes. In this embodiment, each opening 33 is formed in a circular shape. The shape and number of the openings 33 can be changed arbitrarily.

[0076] The accessory 1 may be provided in a state where the base member 13, the chin guard 4, and the shield 5 are integrated. When the accessory 1 is mounted on the helmet body 2, the flange 11 of the helmet body 2 may be inserted from the front into the gap formed between the lower edge of the base member 13 and the left and right stopper portions 21. As a result, the upper surface 11A of the flange 11 abuts against the lower edge of the base member 13, the left and right side edges 7B of the shell 7 abut against the left and right stopper portions 21, and the rear surface 7D of the shell 7 abuts against the front surface of the base member 13, thereby determining the position of the base member 13 relative to the shell 7. In this state, the base member 13 is fastened to the shell 7 by the fastening member 15. As a result, the helmet 3 composed of the helmet body 2 and the accessory 1 is formed.

[0077] By fixing the base member 13 to the shell 7, the shield 5 and the chin guard 4 are attached to the helmet body 2. Thus, it is possible to provide the accessory 1 that can attach the shield 5 and the chin guard 4 to the helmet body 2. In addition, it is possible to provide the helmet 3 having the shield 5 and the chin guard 4. The user can expose the user's face forward by moving the chin guard 4 and the shield 5 upward from the shell 7.

[0078] Since the base member 13 is arranged along the outer surfaces of the shell 7 and the flange portion 11, the base member 13 improves the rigidity of the shell 7. Thus, the safety of the helmet 3 can be improved.

[0079] When the chin guard 4 is located at the first position, the first contact portions 23 of the left and right ends 13A of the chin guard 4 contact the first stoppers 22 of the left and right ends 13A of the base member 13 in the front-rear direction, so that the base member 13 and the chin guard 4 cooperate to form a ring structure. Thus, when the chin guard 4 is located at the first position, the chin guard 4 is supported by the base member 13 from the rear. As a result, the position of the chin guard 4 relative to the shell 7 and the base member 13 is stabilized, and the safety of the helmet 3 is improved.

[0080] The base member 13 abuts against the rear surface 7D of the shell 7 and the upper surface 11A of the flange portion 11, whereby the base member 13 is supported by the flange portion 11. In addition, the left and right locking portions 21 abut against and lock against the end surfaces of the left and right side edges 7B of the shell 7. Thus, the position of the base member 13 relative to the shell 7 is stabilized, and the safety of the helmet 3 is improved.

[0081] The above is the end of the description of the specific embodiment, but the present invention is not limited to the above embodiment and can be widely modified. For example, a clamp for clamping the left and right side edges 7B of the housing 7 can be provided on the left and right stopper portions 21, and the base member 13 and the housing 7 can be combined by the clamp. In this case, the fastening member 15 for combining the base member 13 and the housing 7 can also be omitted. The clamp can have a pair of plate portions that clamp the left and right side edges 7B of the housing 7 from the inner surface side and the outer surface side. The plate portions can be fastened to each other by screws or the like. The clamp can also clamp the flange portion 11.

[0082] The helmet 3 of this embodiment allows the helmet body 2 that can be used alone to be used in reverse front and back directions. Therefore, it is preferred to change the front and back directions of the impact absorbing pad and interior trim of the helmet body 2 relative to the shell 7 to match the shape of the user's head.
