Description

[Detailed description of the invention] A. Purpose of the invention (1) Industrial application field The present invention relates to a full-face helmet.

(2) Conventional technology Conventionally, in such helmets, when the wearer is wearing the helmet, the cap body is generally open at the back of the wearer's neck. For this purpose, it has already been proposed to provide a neck pad on the rear inner surface of the cap body that can elastically contact the neck from the rear side (see, for example, Japanese Utility Model Application No. 61-206632).

(3) Problems that the invention aims to solve By the way, if the cap body is open at the back of the neck, when riding a motorcycle at high speed, air will be drawn into the cap body at the back of the neck. There is a problem in that the entanglement of neck pads causes harsh wind noise, and this problem of wind noise cannot be solved even in helmets equipped with the neck pads described above. This is because even in such a helmet, there is a cross section approximately V that opens to the outside between the neck pad and the neck.
A character-shaped gap is created, and air gets caught in the gap, causing a considerable amount of wind noise similar to the one described above.

The present invention was developed in view of the above circumstances, and provides a full-face helmet that can prevent wind noise from being generated as much as possible by preventing air from being trapped behind the neck. The purpose is to

B. Structure of the device (1) Means for solving the problem In order to achieve the above purpose, the present device has a structure in which elasticity is applied to the wearer's neck from the rear side on the rear inner surface of the cap body that covers the wearer's head. A flexible neck cover is attached to the neck pad, which can come into contact with the neck pad, and a flexible neck cover for closing from below a gap formed between the neck pad and the neck and opening to the outside of the cap body. It is characterized by being provided with an outlet for discharging it to the outside.

(2) Effect According to the above configuration, the gap between the wearer's neck and the cap body can be closed by the neck pad, and in addition, the gap formed between the neck pad and the wearer's neck and opened to the outside can be closed. Since the gaps can be closed with the neck cover, it is possible to effectively prevent the generation of harsh wind noise caused by air entrainment in these gaps and crevices, and in particular, the neck cover itself is flexible. This makes it possible to bring the tip of the cover into close contact with the curved surface of the neck.

Moreover, since the air inside the neck cover can be discharged from the exhaust port provided in the neck cover, there is no risk of the area around the neck getting stuffy even if the neck cover is covered with the neck cover.

Next, the operation of this embodiment will be explained. Assuming that the chin cover 31 is attached to the cap body 1 while traveling at high speed on a motorcycle or the like, the sealing member 33 of the chin cover 31 comes into contact with the wearer's chin from below. Since the gap between the cap body 1 and the chin is closed, air is not drawn into the cap body from below the chin during high-speed driving, thereby preventing inconveniences such as drying the wearer's eyes. It can be prevented. Moreover, the chin cover 31 is the cap body 1
Since the chin cover 31 can be attached to and detached from the chin cover, it is easy to remove the chin cover 31 when it is hot.

In addition, the intake hole 40 for preventing fogging by circulating air along the inner surface of the shield plate 9 is formed in the shape of a long slit in the horizontal direction, and the shutter 41 is designed to slide in the vertical direction. , the intake hole 40 can be opened and closed simply by slightly sliding the shutter 41 up and down.

Further, the gap between the wearer's neck and the cap body 1 can be closed with a neck pad 66, and the gap formed between the neck pad 66 and the wearer's neck and having a generally V-shaped cross section and opening to the outside can be closed by a neck pad 66. Since the neck cover 65 can be used to close the gap, it is possible to effectively prevent harsh wind noise from being generated due to air being trapped in these gaps. Moreover, since the neck cover 65 is provided with an exhaust port 69, the air around the neck is exhausted from the exhaust port 69, thereby preventing the hot and humid atmosphere caused by the neck being covered with the neck cover 65. can be avoided.

Incidentally, the air introduced into the cap body 1 through the intake hole 40 and the air intake port 51 flows as shown by the arrows in FIG. The exit 60 is the cap body 1
Since the outlet passage 63 connected to the air outlet 60 extends to the rear side, the air suction effect due to the airflow flowing through the side of the cap body 1 when driving is improved. This allows air to be exhausted more efficiently. Moreover, air outlet 60
Since the opening end of the cap body 1 is covered with the air guiding member 63, rain or the like will not enter the cap body 1 through the air outlet 60.

Furthermore, the minimum opening degree of the shield plate 9 is determined by the rotation of the operating lever 27, so by once determining the position of the operating lever 27, the minimum opening degree of the shield plate 9 can be kept constant. It's convenient.

Furthermore, the opening/closing plate 57 for opening and closing the air intake port 51 is not only sandwiched between the passage member 54 and the cover 55 at its upper and lower edges, but also has a single strip extending between both side edges of the window 56. Since it is also supported by the support portion 59, it is possible not only to reliably prevent the opening/closing plate 57 from falling off the window 56, but also to have an excellent appearance.

C. Effects of the invention As described above, according to the invention, a neck pad that can elastically contact the wearer's neck from the rear side is provided on the rear inner surface of the cap body that covers the wearer's head, and this neck pad and the A flexible neck cover for closing the gap formed between the neck and opening to the outside of the cap body from below is attached, so that the gap between the wearer's neck and the cap body can be closed with the neck pad, and the neck pad The neck cover can close the gap formed between the neck and the wearer's neck that opens to the outside, thereby preventing the generation of harsh wind noise caused by air entrainment into these gaps and crevices. This can be effectively prevented and is particularly advantageous when driving at high speeds. Furthermore, since the neck cover itself is flexible, it is possible to bring the tip of the cover into close contact with the curved surface of the neck, thereby more reliably achieving the above-mentioned effect of preventing air entrainment. It feels soft when worn and fits well around the neck.

Further, the neck cover is provided with an outlet for discharging the air inside the cover to the outside, so that even if the neck is covered with the neck cover, the area around the neck can be prevented from becoming stuffy and hot.
