Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a helmet with a shield that is worn to protect the head when riding a two-wheeled vehicle such as a motorcycle.

``Prior art'' Conventionally, a shield is attached to the helmet body by forming a pivot in a through hole in the helmet body, and fitting a through hole provided at the end of the shield to the pivot. A helmet is used, but in conventional helmets with shields, if the size and position of the holes in the helmet body are not set correctly, the axis will shift from the correct position, making it impossible to attach the shield to the correct position. Nakatsuta.

``Problem to be Solved by the Invention'' The present inventor has discovered that even if the size and position of the through hole in the helmet body are somewhat accurate, the shield can be placed in the correct position by providing the pivot in the correct position. As a result of research into a helmet with a shield that can be attached to a helmet, the present invention was achieved.

``Means for Solving the Problems'' The present invention provides a helmet with a shield, which has a helmet body and a shield rotatably attached to the helmet body by a pivot, in which a screw is inserted into a through hole of the helmet body on both the inside and outside surfaces. A screw receiver having a cylindrical portion having an outer diameter smaller than the provided through hole and a flange portion having an outer diameter larger than the provided through hole, and a screw provided on the inner surface to be screwed into the thread on the outer surface of the screw receiver. A fastener having a cylindrical part with an outer diameter smaller than that of the above-mentioned through hole and a flange part with an outer diameter larger than that of the above-mentioned through hole is screwed together, and the flange of the screw receiver and the flange of the fastener are screwed together. By holding the helmet body, a pivot shaft with an internal screw provided in the through hole of the helmet body is formed so that its center axis can be adjusted, and a through hole provided at the end of the shield is fitted to the pivot shaft. This invention relates to a helmet with a shield, characterized in that the shield is attached to the helmet body by screwing a set screw into a screw in the pivot.

"Example" The present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view showing an example of a helmet with a shield according to the present invention, FIG. 2 is a partial sectional view showing a shield attachment mechanism in the helmet with a shield shown in FIG. 1, and FIG. FIG. 2 is a partial perspective view showing some of the components of the shield attachment mechanism in the shielded helmet shown in FIG. 1;

A helmet with a shield according to the present invention includes a helmet body 1 and a shield 4 rotatable on the helmet body 1 by a pivot 3 so as to cover a window 2 provided at the front of the helmet body 1. .

The outer shell 5 of the helmet body 1 is provided with through holes 6 on both the left and right sides of the head. A helmet main body is formed by screwing together a screw receiver 7 having a cylindrical part and a flange with screws on both the inside and outside surfaces and a fastener 8 having a cylindrical part and a flange with threads on the inside. A pivot shaft 3 having a screw provided therein is formed in the through hole 6 of 1. In the helmet with a shield according to the present invention, since the pivot 3 is fixed by the flanges of the screw receiver 7 and the fastener 8 sandwiching the outer shell 5, the flanges are attached to the outer shell. By adjusting the position where the body 5 is sandwiched, the pivot 3 can be adjusted to the correct position even if the size and position of the through hole 6 are somewhat inaccurate. A notch 9 is partially formed in the flange of the fastener 8, and a bent surface 10 bent in a zigzag shape is formed, and peaks 11 and valleys 12 alternately provided on the curved surface 10 form a cylindrical portion. It extends radially from the center.

A through hole 13 is formed near both ends of the shield 4, and a bent surface 14 bent in a zigzag shape is formed around the through hole 13, and peaks 15 and troughs 16 alternately provided on the bent surface 14 are formed in the vicinity of both ends of the shield 4. They extend radially around the hole 13. Further, a claw 17 that is fitted into the notch 9 is provided on the bent surface 14 in a protruding manner.

After fitting the through holes 13 and wave washers 18 formed near both ends of the shield 4 to the pivot shafts 3 formed on both left and right heads of the helmet body 1, the screws provided on the setscrews 19 and the pivot shafts 3 are fitted. The shield 4 is rotatably attached to the helmet body 1 by means of a pivot 3 by screwing together a screw provided inside.

In the shielded helmet shown in FIGS. 1 to 3, the zigzag bent surfaces 10 and 14 are pressed against each other by the wave washer 18, so that when the shield 4 rotates, the bent surfaces 10 and 14 are pressed against each other.
0 and 14 are slid against each other, and the bent surfaces 10 and 1
The shield 4 can be stably opened to any stage with the peaks and valleys 16 and the valleys 12 and peaks 15 of the shield 4 aligned.

Further, in the shielded helmet shown in FIGS. 1 to 3, by fitting the claws 17 into the notches 9, it is possible to prevent the shield 4 from rotating excessively.

``Effects of the Invention'' The helmet with a shield according to the present invention has the advantage that even if the size and position of the through hole 6 in the helmet body 1 are somewhat inaccurate, the pivot 3 can be provided in the correct position, so that the shield 4 can be fixed. can be mounted in a precise position.
