Description

[Detailed Description of the Invention] This invention relates to a shield mounting structure for a full-face helmet.

Conventional shield installation on full-face helmets involves bending a flat shield along the curved surface of the helmet body, rotatably attaching both sides of the upper part of the shield to the helmet body with set screws, and attaching both lower sides of the shield to the helmet body with set screws. It is fixed to the helmet body using hook buttons, etc.

Therefore, holes are drilled on both sides of the upper part of the shield for inserting the set screws, but the positions of the left and right holes should be the same as the distance between the left and right screw holes on the helmet body side. However, it is very difficult to open them at the same intervals, and in order to improve workability when installing the shield, the left and right through holes should be made with large diameter holes, respectively, so that they can be adjusted even if there is some misalignment. be.

Therefore, when attaching the above-mentioned shield to the front of the helmet body, first, the hook buttons attached to both sides of the lower part of the shield are engaged with the hook buttons on the helmet body side, and then the through holes on both sides of the upper part of the shield are engaged. Align it with the screw hole on the side of the helmet body, and attach it by pivoting it with a set screw. However, if the shield is not needed after attaching the shield, remove the hook buttons on both sides of the bottom and tighten the set screws on both sides of the top. Rotate the shield above the helmet body as the center, and when necessary, rotate the shield downward and attach the hook button.

However, the holes that can be drilled on both sides of the upper part of the shield are large diameter holes, so when the shield is rotated, the shield moves vertically or horizontally, and the hook buttons on both sides of the lower part are connected to the hook buttons on the helmet body. Even if you tried to make them fit together, they would not match, causing the inconvenience of having to loosen the set screw and start over from the beginning.

Therefore, the present invention solves the above-mentioned inconvenience and makes it possible to securely attach the hook and button.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
1 is the helmet body, which is made of a glass-reinforced plastic material such as a mixed material of glass fiber and polyester resin, and has a shell that is molded into a shape that fits the entire face (so-called full face), and is attached to the inner surface of the shell. A shield 2 is made of a shock absorbing material such as cork material or urethane foam, a window hole 9 is formed by cutting out the central part of the front surface of the helmet body 1, and a transparent plate is formed on the front surface of the window hole 9. is attached so that it can be rotated and detached freely.

Further, a screw member 10 into which a set screw 6 for pivoting the shield 2 is screwed is integrally buried and fixed in the upper left and right sides of the window hole 9 of the helmet body 1, and screw members 10 on both sides of the lower part of the window hole 9 are embedded and fixed. Attach the hook button (shown in the figure) that engages the hook button 11 attached to the.

Through holes 3 are drilled through the upper left and right sides of the shield 2, hook buttons 11 are attached to the lower left and right sides so that the attachment position can be adjusted, and a bushing 4 is fitted into the through holes 3.

The bushing 4 is formed of a synthetic resin material into a cylindrical shape with both ends open, and the - side edge (upper edge in the drawing) is made to protrude outward to form an engaging protrusion 4' in the same body. When fitted into the through hole 3 of the shield 2, the engaging protrusion 4' abuts and engages with the upper edge of the through hole 3, so that the bush 4 is held within the through hole 3 of the shield 2. It is.

Further, a hole 5 having a diameter larger than the shaft diameter of the set screw 6 is drilled through the bushing 4 so as to be eccentric from the center of the bushing 4.

Therefore, by rotating the bushing 4 with the bushing 4 fitted into the through hole 3 of the shield 2, the set screw 6 can be adjusted to a position where it can be securely screwed into the threaded member 10 of the helmet body 1. You can choose.

Reference numeral 7 denotes a non-slip plate, which is made of a rubber plate or the like, and is placed below the bushing 4 and is not placed on the helmet body 1. After the bushing 4 is pressed by tightening the setscrew 6, the non-slip plate becomes a non-slip plate. 7 is crushed and deformed.

Reference numeral 8 is a washer of a size such that the bushing 4 is hidden by a material such as Hewi birch wood.The washer 8 is placed on the top surface of the bushing 4, and the set screw 6 is inserted from above and screwed into the screw member 10 of the helmet body 1. do.

Since the shield mounting structure of the present invention has the above configuration, when the shield is moved up and down, the shield rotates around the bushing, which solves the problem of misalignment of the shaft support of the shield. As a result, the relative positional relationship between the hook button on the shield side and the hook button on the helmet body side can be maintained normally for a long period of time.

Furthermore, since the set screw that pivotally supports the shield is screwed into the helmet body through a bushing that has an eccentrically drilled hole, the bushing can be rotated to connect to the threaded member (female thread) on the helmet body side. You can select the optimal position for screwing the set screw.

Therefore, there is no need to accurately drill holes on the shield side in accordance with the positions of the hook buttons and screw members on the helmet body side as in the past, and workability can be improved.

In other words, in conventional shield installation, the shield is pivotally supported on the helmet body side with a set screw, which causes a misalignment between the shield side, the hole, and the female screw on the helmet body side, which occurs when the shield is pivoted. If this happens, the hole on the shield side should be made larger in diameter than the female screw hole so that this can be corrected to some extent.

This causes problems such as when the shield is moved up and down after the shield is attached, the hole moves around the set screw, changing the position of the hook button on the helmet body and the shield, making it impossible to engage and disengage.

However, the present invention can reliably prevent such problems and eliminate the conventional inconvenience of having to loosen the set screw and reinstall the shield. There is.

Therefore, the intended purpose can be achieved.
