Description

[Detailed description of the invention] "Industrial application field" This invention relates to a helmet screen device.
In particular, the present invention relates to a screen device for a helmet such as a motorcycle in which a shield plate or a windshield is not integrally attached to the helmet body in advance.

``Conventional Requirements'' In general, riding helmets can be classified into two types depending on whether or not the cap body is provided with a screen or a windshield. For example, a simple helmet with a flange generally does not have a windshield, while a full-face helmet has a rotatable screen.

However, in recent years, as the number of young people who love motorcycles has increased, the helmets used when riding motorcycles are not only of the above-mentioned type, but also due to their safety, convenience, design, etc. There is a demand for new types that take into account tastes and other factors.

Therefore, before filing the application for the present invention, the applicant proposed a base plate that is removably attached to the front surface of the outer wall of the helmet body via a fastener, and a guide piece that is guided by guide pieces provided at the left and right ends of the base plate. and a screen plate provided with a protruding shaft in the center of the outer wall surface, a protective plate fixedly attached to the base plate or the guide piece so as to cover the screen plate and having a guide elongated hole for the protruding shaft; proposed a helmet screen device consisting of an operating piece provided on the protruding shaft protruding from the plate and for pulling out the screen plate from the protection plate to an arbitrary position and fixing it (see Japanese Utility Model Application No. 50773/1983). .

However, in the case of the above-mentioned invention, although it is said that it can be reminiscent of a new type of helmet by considering safety, coolness, and ease of use, it only has one screen plate.
In addition, since the protruding shaft is provided in the center of the outer wall surface of the screen board, the screen board cannot fully function as a sun visor (sunshade), and the operating piece provided on the protruding shaft is protected. The problem was that it protruded significantly from the center of the outer wall surface of the board, making it dangerous.

"Problems to be Solved by the Present Invention" The present invention attempts to solve the following objects in view of the conventional demands and the problems of the aforementioned device of the applicant's earlier application.
