Hereinafter, embodiments of the present invention will be described based on the drawings.
In the first embodiment shown in FIGS. 1 to 3, the jet type helmet 1 has a helmet main body 3 for covering the head a and an opening of the helmet main body 3 mounted rotatably on the helmet main body 3 and forward of the face a 1 And a shield 4 covering the portion 3A.
Since the jet type has no chin guard arm in the helmet body 3, the opening 3A is formed on substantially the entire front of the helmet body 3, the shield 4 can cover substantially the entire front of the face a1, and the helmet position from the covering position It can be retracted above the main body 3.

The shield 4 has a substantially arc shape with a large diameter curvature in a side view (FIG. 1), and a substantially arc shape with a small diameter curvature in a plan view (FIG. 3). It has the mounting part 4C mounted | worn freely.
In the shield front surface portion 4A of the shield 4, a bulging portion 5 is formed from the facing portion facing the front side mouth a2 and the nostril a3 of the head a to the shield lower edge 4D. The bulging portion 5 protrudes in the forward direction from the peripheral portion thereof, and therefore, on the shield inner surface 4B side of the bulging portion 5, an oro-nasal facing concave portion 5B opposed to the mouth a2 and the nostril a3 is formed.

The entire area of the shield 4 is substantially the same thickness, and the formation of the forwardly projecting bulging portion 5 on the front surface simultaneously forms the oro-nasal facing concave portion 5B on the back surface. The shield 4 is formed by vacuum molding a synthetic resin such as hard polycarbonate, so the bulging portion 5 and the oro-nasal facing concave portion 5B can be easily formed by processing a mold.
It is preferable that the oro-nosed portion 5B has a step difference of 2 to 20 mm from the inner surface 4B of the shield, and the outer peripheral portion 6 of the oro-nosed portion 5B is substantially mountain shaped in front view as shown in FIG. The lower part of the recess 5B is opened downward, so that human breath can flow out and outside air can flow in.

The guard member 7 which protrudes to the face a1 side is attached to the outer periphery of the nose-nose facing recess 5B on the shield inner surface 4B. The guard member 7 is formed of rubber, soft resin or the like, and has a substantially mountain shape in a front view similar to the outer peripheral portion 6 of the nose-opposition facing recess 5B, and a cross section of the mounting portion 7a and the protrusion 7b. Is approximately L-shaped.
The mounting portion 7a of the guard member 7 is located on the side of the nose-to-nose facing recess 5B with respect to the protrusion 7b, and an adhesive, double-sided adhesive tape, etc. It is attached via. The guard member 7 constitutes a breath guard which strongly regulates the flow of human breath toward the shield inner surface 4B in combination with the oro-nasal facing concave portion 5B.

  The tip end of the projection 7b of the guard member 7 is preferably close to the face a1. For example, the projection 7b has a projection amount of 2 to 15 mm from the inner surface 4B of the shield. The left and right lower part is narrow. The protrusion 7 b of the guard member 7 has a protrusion amount that does not interfere with the upper portion of the helmet body 3 when the shield 4 is retracted above the helmet body 3.

FIG. 4 shows a second embodiment of the present invention, in which the mounting structure of the guard member 7 is different from that of the first embodiment, and the projecting portion 7b is located on the side of the nose facing recess 5B with respect to the mounting portion 7a. The inner surface (lower surface) has an arc shape in cross section, and is formed so as to be smoothly connected in an arc shape to the outer peripheral portion 6 of the nose-opposition facing recess 5B.
FIG. 5 shows a third embodiment of the present invention, in which the mounting structure of the guard member 7 is different from that of the first embodiment, the mounting portion 7a of the guard member 7 is bonded to the outer peripheral portion 6 of the oronasal facing recess 5B. ing. Therefore, in the cross section, the mounting portion 7a is in a shape that contacts the outer circumferential portion 6 of the oronasal facing recess 5B in an arc shape in the cross section. The protrusion 7b of the guard member 7 is formed in an arc shape or a straight shape by extension of the attachment portion 7a.

FIG. 6 shows a fourth embodiment of the present invention, in which a breath guard is configured only with the outer peripheral portion 6 of the oro-nasal facing concave portion 5B. The outer peripheral portion 6 is a circular arc having a smaller radius of curvature than that of the first embodiment in cross section, and the inner surface thereof is positioned slightly above the edge of the shield inner surface 4B on the side of the nose-nose facing recess 5B, and human breath goes to the shield inner surface 4B. The outer peripheral portion 6 alone can regulate the flow.
FIG. 7 shows a fifth embodiment of the present invention, in which the shield front surface portion 4A has a smooth spherical shape without the bulging portion 5, and the shield from the portion facing the mouth a2 and nostril a3 of the shield front surface portion 4A. A guard member 7 having a substantially mountain shape in a front view projecting to the face a1 side is attached to the shield inner surface 4B up to the lower edge 4D. By attaching the guard member 7, a nose-opposition facing recess 5 B surrounded by the guard member 7 is formed on the shield inner surface 4 B.

In the first to third embodiments, after the mouth-nose-facing recess 5B is formed by the bulging portion 5, the mouth-nose-facing recess 5B formed by the guard member 7 is further polymerized to form a deep mouth-nose facing recess 5B. However, in the fifth embodiment, the mouth-nosed facing recess 5B is formed only on the guard member 7 on the shield inner surface 4B.
As in the fourth embodiment, the guard member 7 alone can restrict the flow of human breath to the shield inner surface 4B by the guard member 7 alone, and into the shield 1 from the shield lower edge 4D as in the fourth embodiment. Can reduce the wind of wind.

In the helmet shield 1, when a person covers the helmet body 3 on the head a and lowers the shield 1 to cover the opening 3A, the person exhales from the mouth a2 or the nostril a3 in the front of the mouth nose. Since the outer peripheral portion 6 of the oro-nose opposite recess 5B is a recess divided by the shield inner surface 4B, the flow of human breath to the shield inner surface 4B side is restricted.
The guard member 7 provided on the outer peripheral portion 6 of the oro-nasal facing concave portion 5B guides to the face a1 side away from the shield inner surface 4B even when human breath flows out from the oro-nosal facing concave portion 5B in combination with the outer circumferential portion 6 The flow to the shield inner surface 4B is effectively restricted. In addition, wind entrapment from the shield lower edge 4D into the shield 1 can be reduced, and the influence on the face a1 can be suppressed.

The outer peripheral portion 6 of the mouth-nosed recess 5B is also a partition wall that restricts trapping and spreading of human breath, and also serves as a partition wall that restricts the wind of wind from reaching the eyes of the face a1. ing.
The present invention is not limited to the above-described embodiment, and the shapes, configurations, combinations, and the like of the members may be changed.

For example, the guard member 7 may be integrally formed on the shield inner surface 4B of the shield 1.
In the guard member 7, the attachment portion 7 a may have a substantially uniform width over the entire length, and the protrusion 7 b may also be formed with a substantially uniform width over the entire length.
The outer peripheral portion 6 of the mouth-nose-facing recess 5B of the shield inner surface 4B may be formed in a reverse U-shape in a front view.

  Although the shield 1 is illustrated for the jet type, it may be applied to the shield of a full face type helmet having a chin guard arm.
