Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a motorcycle helmet, and more specifically to a motorcycle helmet wherein a shield, visor and jaw guard are configured so as to be rotated with one hinge point to make it easy to assemble and use, while the operation and structure of the visor are modularized into one to reduce cost and improve productivity. [0003] 2. Description of the Related Art [0004] Motorcycle riders must wear a safety helmet to protect the head and the front of helmet should have a shield installed to prevent sight obstruction and breathing difficulty due to winds blowing from front. [0005] And to protect the jaw of the wearer, a jaw guard is provided at the bottom of the helmet in the jaw portion. Both ends of this jaw guard are pivotably mounted on hinge portions installed on both left and right sides of the helmet body, so as to be adjusted suitably according to the shape of the face of the wearer. [0006] Also, a visor can be provided to intercept sunlight coming directly into the eye in daytime. Such a visor is also pivotably mounted on the hinge portions installed on both left and right sides for use by moving up or down as necessary. [0007] As described above, the conventional helmet has components that need to be opened or closed as necessary, such as the jaw guard, shield and visor, but conventionally there were no helmets in which these three components can be opened and closed around one shaft. [0008] In the visor of the conventional helmet, the visor portion that can be opened or closed, the pivot for opening and closing this visor, and the operating lever are configured individually as separate parts and they are in such a structure that makes it very difficult to assemble these together with the shield and jaw guard, so it is not suitable for mass production. SUMMARY OF THE INVENTION [0009] Accordingly, it is an object of the present invention to provide a motorcycle helmet having a jaw guard, shield and visor, all of which can be pivoted around one pivot shaft. [0010] Another object of the present invention is to provide a motorcycle helmet wherein all the modules can be easily assembled in one place after the modularized visor parts of an opening and closing structure are produced separately in another production place. [0011] In accordance with the present invention, there is provided a motorcycle helmet comprising: a helmet body in which an opening for the face is provided on front and pivot holes are formed on both left and right sides; a jaw guard which protects the jaw of the wearer by covering part of the opening of the helmet body and which can be pivotably moved by hinge portions provided on the extending portions of both left and right sides as a hinge point; a shield which opens and closes the remaining part of the opening above the jaw guard and which can be pivotably moved by latch pivot portions provided on extending portions on both left and right sides as a hinge point; a visor which intercepts sunlight incoming into part of the opening in the helmet body and which can be pivotably moved by the lever mechanisms on both left and right sides having control levers as a hinge point; and a fastening screw which is screwed to pivot holes on both left and right sides of the helmet body so as to pivotably move all of the hinge portion of the jaw guard, the latch pivot portion of the shield, and the lever mechanisms of the visor by making pivot holes as a hinge point. [0012] Preferably, the visor is modularized by comprising a visor body including a visor portion for intercepting sunlight incoming into part of the opening in the helmet body, and extending portions extended to left and right from the visor portions and having visor pivot holes and lever inserting holes formed at the position eccentric with the visor pivot hole; a control lever including a protuberance at one end thereof which is inserted into the lever inserting hole of the visor body, and a lever pivot hole at the other end thereof; a lever arm which is inserted into the lever pivot hole of the control lever; a fastening plate which has a visor pivot inserted into the visor pivot hole of the visor body and a lever pivot inserted into the lever pivot hole of the control lever, and which can fix these on the inside of the helmet body; a guide flap which is fixed at one end of the lever arm of the control lever to be introduced within a predetermined range of movement according to the rotation of the lever arm; and an adjusting knob which is joined to the lever arm of the control lever by passing through the guide flap and moves within a predetermined range along an arc hole formed on the side of the helmet body.
