Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ventilation system for a full-face helmet worn by automobile racers, motorcycle riders, and the like.

(Prior Art) In conventional full-face helmets worn by motorcycle riders, hot air from the wearer's breath and sweat accumulates in the space between the windshield and the wearer's face, causing the inner surface of the windshield to fog up. There is a risk that the wearer's vision may be obstructed. Therefore, as a ventilation device for a full-face helmet, there is one described in US Pat. No. 4,498,202.
This has a window hole blocked by a windshield plate on the front of the helmet body, and a chin guard located below this window hole, which ventilates the space between the helmet wearer's face and the windshield plate. A ventilation fan is provided for this purpose. This ventilator blows outside air to the inner surface of the windshield or exhausts the inside air from the inner surface of the windshield to the outside, and the ventilator is attached to the outside of the cap body.

(Problem that the invention aims to solve) Generally speaking, it is desirable that the air resistance of a helmet worn when driving at high speeds is as low as possible, but in conventional helmets, the ventilator is attached to the outside of the helmet. Becomes a resistor. Moreover, it is easily damaged by external impact.

Furthermore, with ventilation using only intake or exhaust air from a fan, the air on the inner surface of the windshield does not move well, resulting in a delay in ventilation on the inner surface of the windshield, and fogging on the inner surface of the windshield. When cloudiness occurs, there is a great danger in not removing the cloudiness as soon as possible.

The object of the present invention is to provide a ventilation system for a full-face helmet that eliminates the above-mentioned problems.

(Means for Solving the Problems) The specific means taken by the present invention to achieve the above object is characterized by a window hole in the front of the cap body 2 that is closed by a windshield plate 5. 4 and a chin guard 6 located below the window hole 4, and a ventilation device for a full-face helmet, which is equipped with a ventilator for ventilating the space between the helmet wearer's face and the windshield plate 5. A pair of ventilators 10 and 11 are provided on both sides of the inner side of the chin guard 6, and these ventilators 10 and 11
One is at least one suction ventilator 10 that sucks outside air from the lower side of the cap body 2 and blows it to the inner surface of the windshield 5, and the other is the inner surface of the windshield 5 that draws inside air from the wearer's face side. At least one suction ventilator 11 that sucks in from the side and discharges to the lower side of the cap body 2
The point is that

(Function) When ventilating the space between the inner surface of the windshield plate 5 of the helmet 1 and the helmet wearer's face, a pair of ventilators 10 and 11 arranged on both sides of the inner side of the chin guard 6 are used. Activate. Then, the suction fan 10 sucks outside air from below the cap body 2 into the windshield plate 5.
Air is blown to the inner surface side, and a suction ventilator 11 sucks in air from the wearer's face side from the inner surface side of the windshield plate 5 and discharges it below the cap body 2. Therefore, chin guard 6
The outside air sucked in from below one side of the windshield plate 5
The air is blown toward the inner surface of the windshield, moves along the inner surface to the other side of the chin guard 6, and is discharged to the lower part of the other side along with the inside air on the inner surface of the windshield plate 5. In addition, the helmet does not receive extra wind resistance while driving, and
Even if a shock is applied to the helmet due to a fall of a motorcycle, etc., the ventilators 10 and 11 are not easily damaged.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The cap body 2 of the full-face helmet 1 is formed into a dome shape from hard reinforced synthetic resin, etc., and has an opening 3 at the bottom for covering the helmet, and a window hole 4 at the front for ensuring visibility. A windshield plate 5 is mounted to open and close the window hole 4, and the windshield plate 5 is made of a transparent or translucent material such as synthetic resin. Further, a chin guard 6 is integrally provided at the lower part of the window hole 4. A shock absorbing liner 7 made of foamed polystyrene or the like is attached to the inner surface of the cap body 2 according to the shape of the inner surface.
Furthermore, a head cushion 8 for protecting the top of the wearer's head is lined on the top side of the inner surface of the shock absorbing liner 7, and a side cushion 8 is lined on the bottom side, and these cushions 8, 9 is made of a material such as urethane foam. The side cushion 9 includes a ring-shaped cushion material 9a that protects the frontal, temporal, and occipital parts of the wearer, and a pair of left and right block-shaped cushion members 9b, 9b that correspond to the wearer's cheeks. still,
No cushioning material is provided on the inner surface of the shock absorbing liner 7 on the inner surface of the chin guard 6 at positions corresponding to the nostrils and mouth of the wearer in order to improve the wearer's breathing.

A pair of ventilators 10 and 11 are arranged on both sides of the inside of the chin guard 6 to ventilate the space between the wearer's face and the windshield plate 5. These ventilators 1
0 and 11 are suction ventilators 1, one of which sucks outside air from below the cap body 2 and blows it toward the inner surface of the windshield plate 5;
0, and the other is a suction ventilator 11 that sucks in air from the wearer's face side from the inner surface of the windshield plate 5 and discharges it below the cap body 2. The suction fan 1
0 is arranged in a dead space that is a corner between the right side block-shaped cushion material 9b of the side cushion 9 and the inner surface of the shock absorbing liner 7 on the inner surface of the chin guard 6, and a part of the suction ventilator 10 absorbs the shock. It is recessed in the absorbent liner 7. This results in
The suction ventilator 10 does not become an obstacle when the helmet 1 is put on and taken off. The suction fan 10 includes a cylindrical case 12 with open upper and lower ends, an electric motor 13 and an impeller 14 built into the case 12, and the electric motor 13 is located approximately in the center of the case 12. The output shaft 16 is located on the inner surface of the case 12 by a support plate 15, and its output shaft 16 projects toward the upper opening of the case 12. The impeller 14 of the output shaft 16 is fixedly installed. Suction ventilator 11
is generally the same as the suction fan 10, and the difference is that it is provided on the left side of the chin guard 6, and the impeller 14' is provided on the lower opening side of the case 12'. Note that the suction ventilator 10 and the suction ventilator 11 may be left and right reversed, or may be provided in plural numbers. moreover,
The pair of ventilators 10 and 11 are preferably axial fans, but may also be Sirotskov fans, centrifugal fans, or the like.

A temperature sensor 17 is attached to the side cushion 9 near the inner surface of the windshield plate 5, and is connected to the electric motors 13, 13' via a power supply device 18, which will be described later. The temperature sensor 17 detects the temperature on the inner surface of the windshield plate 5 and turns on and off the power supply 18, thereby rotating and stopping the impellers 14 and 14'. As a result, each ventilator 10, 11 can be operated to prevent fogging before the inner surface of the windshield plate 5 starts to fog up, so that the wearer's visibility can always be kept good, and This has great safety benefits, such as eliminating the need for unnecessary operations while driving. Also, temperature sensor 1
Since the ventilators 10 and 11 are operated only when necessary, the lifespan of the power supply can be extended and it is also economical.

A power supply device 18 for supplying electric power to the electric motors 13, 13' is provided at the lower rear end of the cap body 2, and this power supply device 18 is provided with a switch 19.
This switch 19 allows the electric motors 13, 13' to be started and stopped manually, or automatically started and stopped via the temperature sensor 17.
Incidentally, the power supply device 18 may be provided separately from the helmet 1 and provided at a suitable location on the rider's body.

(Effects of the invention) In the present invention, the ventilation fan is provided on both sides of the inside of the chin guard 6, so that the helmet 1 does not receive any extra wind resistance while driving, and the ventilation fan is installed on both sides of the inside of the chin guard 6. It is not easily damaged by impact.

Further, a pair of ventilators 10 and 11 are provided on both sides of the inside of the chin guard 6, and one of these ventilators 10 and 11 sucks outside air from the lower side of the cap body 2, and blows the air into the windshield plate.
The other is a suction ventilator 10 that blows air to the inner surface of the wearer's face, and the other is a suction ventilator 11 that sucks in air from the wearer's face side from the inner surface of the windshield plate 5 and discharges it to the lower side of the cap body 2. The outside air sucked in from the lower side of one side of the chin guard 6 is actively blown toward the inner surface of the windshield plate 5, and the blown outside air moves along the inner surface of the windshield plate 5. The air is actively discharged downward from the other side of the chin guard 6 along with the inside air on the inner surface side. Thereby, a good air flow is formed, and the space between the wearer's face and the inner surface of the windshield plate 5 can be quickly ventilated.
