DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to goggles provided with a ventilator for forcibly ventilating internal air with a fan.

[0002]

2. Description of the Related Art During use, goggles sometimes become cloudy due to the condensation of water droplets inside the lens. Clouded goggles have very poor visibility. In order to eliminate the fogging, a method of heating a goggle lens with a heater and a goggle for forcibly ventilating internal air with a fan have been developed. The method of heating the lens can quickly eliminate the fogging, but has the disadvantage of extremely large power consumption. For this reason, there is a disadvantage that the usable time is extremely short using a large battery. Goggles forcibly ventilated with a fan can reduce the power consumption of the motor, so they can be used for a long time with small batteries.

A goggle for forcibly ventilating internal air with a fan is described in the following publication. JP-A-57-34207 JP-A-57-152124 JP-A-62-193222

[0004] These publications describe goggles provided with a ventilation device having the structure shown in FIG. This goggle is
The motor 1 is disposed downward at the center of the upper part, and the fan 2 is fixed to the lower end of the rotating shaft. An inlet 3 is opened below the fan 2 so that the fan 2 sucks the internal air.

[0005]

The goggles having the structure shown in FIG. 1 can forcibly exhaust the internal air by rotating the fan 2 with the motor 1. Therefore, fogging of the goggle lens 4 can be eliminated. However, goggles of this structure are already equipped with commercially available ventilators,
Alternatively, goggles already used for various purposes have a disadvantage that a ventilation device cannot be retrofitted. In the process of manufacturing goggles, it is necessary to provide a part for incorporating a motor with a fan in the goggles and set the motor here.
For this reason, the goggles in this figure need to be prepared for goggles having a shape optimal for various uses, and there is a disadvantage that the number of types is increased and the manufacturing cost is extremely high.

[0006] Goggles are used in a very wide variety of applications. Further, even in specific applications, many types having different shapes and different colors of goggle lenses are used.
Furthermore, large goggles that can be used over glasses are also used. For this reason, the user of the goggles uses the one that is most suitable for the application and has a different shape or lens color according to his or her preference. Ideally, goggles having a ventilating device can be retrofitted to various goggles, instead of specifying the goggles.

[0007] The present invention has been developed to achieve this, and an important object of the present invention is to provide a goggle that is already on the market or in use that is simple, easy, and out of the way. It is an object of the present invention to provide a goggle to which a ventilation device can be attached.
