(Prior art) This type of helmet windshield plate angle adjustment device is
The swinging pivot mechanism of the windshield plate is formed by elastically fitting a fitting protrusion provided on the helmet body into a fitting recess of an angle plate provided angularly around the pivot shaft at the end of the windshield plate. Make sure to hold the windshield in position,
A mounting device for attaching to a helmet has been provided which includes a locking member, an angle disc, a presser disc, and a shaft screw (for example, Japanese Utility Model Application Publication No. 142017/1983).

(Problem to be solved by the invention) However, since the fitting protrusion of the helmet body is fitted into the fitting recess of the angle plate, the rotation range of the windshield plate cannot be restricted when adjusting the angle of the windshield plate. Not only is it difficult to adjust the angle of the windshield plate, but the angle adjustment operation of the windshield plate also lacks smoothness and reliability. Since the fixing member is fitted, the fixing means to the helmet is troublesome and cannot be fixed firmly.

Therefore, this idea was devised to solve the above-mentioned problems, and it is extremely easy to adjust the angle of the windshield to multiple levels simply by rotating the windshield in the vertical direction. Moreover, the present invention provides a helmet windshield plate angle adjustment device that allows the angle of the windshield plate to be adjusted smoothly and reliably in multiple stages, and furthermore, the means for fixing the windshield plate to the helmet is simple and can be firmly fixed. be.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, in this invention, a mounting tool is installed in each mounting hole drilled approximately at the center of both sides of the helmet with a window. At the same time, a rotating shaft having a space of an appropriate thickness at its base protrudes from the outer periphery of the bolt insertion hole in the center of the disc, and the inner periphery of the disc. A pair of fixing protrusions facing each other with the bolt insertion hole as a boundary are provided protrudingly provided on the disk, a guide protrusion is provided protrudingly provided on the outer periphery of the disc, and a plurality of pairs of angle adjustment portions are provided on the periphery of the disc excluding the guide protrusions. A fixing plate of the mounting tool having holes bored therein is inserted into a pair of fixing holes arranged opposite to each other with the mounting hole as a boundary on both outer surfaces of the helmet corresponding to the positions of the flanged nuts. The rotating shaft of each fixing plate has each bolt insertion hole drilled at both ends of the windshield plate for opening and closing the window, and the circular arc-shaped hole provided on the periphery The rotation limiting grooves are fitted into the guide protrusions, respectively, and the plurality of pairs of angle adjustment holes of each of the fixing plates are provided with grooves on the inner peripheral edge of the rotating plate of the attachment that rotates together with the windshield plate. A pair of protruding angle adjustment protrusions are respectively fitted so that the windshield plate can be rotated to adjust the angle in multiple stages, and the bolts of the fixture are attached to each of the flanged nuts, fixing plate, windshield plate, It is designed to be installed by screwing into each bolt insertion hole of a rotating plate or the like.

(Function) By using the technical means described above, when the angle of the windshield is slightly rotated upward from the first stage when it is fully closed, the angle of the windshield is slightly rotated upward around the rotation axis of each fixed plate of the fixture. While the movement limiting groove moves along the guide protrusion, the pair of angle adjustment protrusions on each rotary plate are fitted into the pair of angle adjustment holes on each fixed plate, so that the angle of the windshield plate is adjusted to 2 when the windshield plate is opened/closed by 1/3. It can be adjusted in stages. Furthermore, when the windshield plate is sequentially moved upward in the same manner, a pair of angle adjustment protrusions are fitted into a pair of angle adjustment holes and a pair of angle adjustment holes, respectively, and the angle of the windshield plate is adjusted to 2/3 of the open position. It can be adjusted sequentially to the 3rd stage and the 4th stage when fully opened. In addition, by operating the windshield in the opposite manner as described above and moving the windshield downward sequentially, the angle of the windshield can be adjusted to the 4th, 3rd, and 2nd stage.
