Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding helmet, and more particularly to improvement of a cap body in a full-face type riding helmet.

[0002]

2. Description of the Related Art A full-face type riding helmet has a head that fits easily into the helmet, and a wide window hole is provided on the front surface of the hat body that forms the helmet to ensure a forward field of view and facilitate rearward confirmation. The chin guard below the window is integrally connected to the left and right cheeks to form a durable hat body (helmet).

[0003]

By the way, the strength of the above-mentioned full-face type riding helmet is
Although it is determined by the structure and shape, what is important is that all parts of the helmet are evenly strong, and the major influences on this are the width, thickness, shape (three-dimensional) of the chin guard, etc. If the material is the same, the wider the material is, the thicker the material is the same, the thicker the material is. This is a burden on the operator and is not preferable, and therefore the thickness cannot be extremely increased. Therefore, the strength of the jaw guard is actually determined by the width and the shape.

The opening area of the window hole formed in the conventional full-face type riding helmet may be desired to be wide depending on the application of the helmet and the riding posture. Even in such a case, it is difficult to make the thickness of the jaw guard part extremely thick so as to have the necessary strength because of the molding method, etc. The reality is that the width of the chin guard is narrowed and sufficient strength cannot be secured. Although it is conceivable to increase the thickness of the chin guard as a means for narrowing the width of the chin guard, it is difficult to make it extremely thick beyond the common sense as described above in consideration of the helmet molding method.

Therefore, the present invention has been made in view of the problems of the above-mentioned conventional technique, and its object is to prevent the jaw guard portion from being extremely thicker than a normal jaw guard. It is possible to provide a riding helmet in which the safety surface can be secured while the width of the vehicle is less than about half that of a normal product, and the opening area of the front window hole is widened.

[0006]

[Means for Solving the Problems] The technical means taken by the present invention in order to achieve the above object is to provide a full face type helmet with a chin guard portion of a cap body formed of a fiber reinforced resin material, A pipe-shaped or rod-shaped reinforcing member is embedded and fixed.

The reinforcing member embedded in the chin guard of the cap made of fiber reinforced resin material is a metal pipe (for example, aluminum pipe) having a circular or trapezoidal cross section, or a solid bar material (for example, aluminum pipe) having a low specific gravity (for example, aluminum pipe). Closed-cell hard foam) and the like. The reinforcing member is curved in an arcuate shape so as to match the shape of the chin guard of the cap body, and both ends thereof are flatly crushed so that the inner surface side of the chin guard is finished smoothly.

[0008]

According to the above means, since the reinforcing member is embedded and integrated in the wall thickness of the jaw guard portion, the strength of the jaw guard portion is determined by the width and thickness of the jaw guard made of the fiber reinforced resin material. In addition to being carried by the reinforcing member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a full-face type riding helmet, and 1 is a fiber reinforced resin material, which is well known today and is formed so that the head fits easily. A cap body in the shape of
The shock absorbing liner 2 formed of expanded polystyrene and the like is fitted and fixed to the inside of the
Inside, an interior body 3 such as a ceiling pad, a cheek pad, an ear pad formed of a sponge cushion is equipped.

A window hole 4 is opened on the front surface of the cap body 1,
The window hole 4 is closed or opened by a shield 5 attached to the outside of the cap body 1 so as to be vertically rotatable.

A reinforcing member 7 made of a metal pipe is embedded and integrated along the jaw guard 6 in the wall thickness of the jaw guard 6 below the window 4 in the cap body 1.
Both ends of the chin are flattened so that the inner surface of the chin guard 6 is smoothed. The width of the chin guard portion 6 formed on the cap body 1 (width from the lower hole edge of the window hole to the lower edge of the cap body) is about half the width of the chin guard portion in a normal product.

The reinforcing member 7 embedded in the chin guard portion 6 is not limited to the form described in the above-described embodiment, but a reinforced member 8 made of an aluminum pipe having a substantially trapezoidal cross section as shown in FIG. A curved shape is formed along the portion 6, and both end portions are flattened and crushed to be embedded in the wall thickness as in the previous embodiment, or as shown in FIG. 4, hard foam of closed cells having a low specific gravity. An example is a configuration in which the reinforcing member 9 having a bow-shaped body is embedded and integrated within the wall thickness. In the figure, 10 is a chin strap and 11 is a deflector.

With the above-described structure, the jaw guard portion 6 of the cap body 1 and the fiber reinforced resin material itself forming the cap body 1 and the reinforcing member 7 embedded in the resin material of the cap body 1 are integrated.
The reinforcing member 7 is reinforced by (or 8, 9), and compensates for the narrowed width of the jaw guard portion 6 to secure the strength required as a helmet.

[0014]

As described above in detail, the riding helmet of the present invention has a pipe-shaped or rod-shaped reinforcing member embedded and fixed to the chin guard portion of the cap body formed of the fiber reinforced resin material. Even if the width of the jaw guard portion is narrowed to about half or less of the width of the jaw guard portion in a normal product, sufficient strength can be secured and safety can be maintained. And as a result of being able to make the width of the jaw guard part less than about half of the normal product,
The opening area of the window hole opened on the front of the cap body, especially the opening width in the vertical direction, can be opened significantly wider than the normal product,
Therefore, it is possible to provide a helmet capable of easily confirming the front view and the rear view.
