Description

  The present invention relates to goggles that are worn when skiing, performing other sports, driving a motorcycle, or performing various operations at a site such as a factory, architecture, or civil engineering.

  Conventionally, when wearing goggles and skiing or driving a motorcycle, the lens may become cloudy. The reason for the fogging of the lens is that when the wearer sweats, the humidity of the air in the goggles near the face increases. Also, under extremely cold conditions, condensation may occur on the inner surface of the low-temperature lens, resulting in cloudiness.

  Conventional goggles include a lens provided with a vent hole in order to prevent such fogging of the lens, and a frame provided with a vent hole for holding the lens.

  For example, the lens itself is provided with a ventilation hole. For example, a relatively large ventilation hole is provided in a lens fitted in a frame, and a covering member is detachably attached to the surface of the lens so as to cover the ventilation hole. In some cases, the covering member is formed with a hole at a position corresponding to the vent hole in the attached state, and the hole is covered with a thin plate filter (Patent Document 1).

  In addition, for example, a frame that holds a lens is provided with a ventilation hole. For example, the frame includes a frame and a lens that is detachably fitted in a groove provided in an inner peripheral portion of the frame. A plurality of through holes are provided, and front and rear walls constituting the groove of the frame are provided with opposing ventilation openings (Patent Document 2).

  Further, some conventional goggles have a lens provided with an anti-fogging coating in order to prevent such fogging of the lens. However, this anti-fogging coating alone is not sufficient and is easily scratched, so that the field of view seen through the lens may be hindered. In particular, when the user wipes the fog formed on the inner surface of the goggles, the thin anti-fogging coating is scratched or peeled off.

  For this reason, goggles have been proposed in which two lenses are used to ensure antifogging properties and the antifogging coating is not scratched or peeled off. For example, the outer lens and the inner lens are fitted in a frame in parallel, and the outer lens and the inner lens are sealed at the periphery or the vicinity thereof, and an empty space is provided between the outer lens and the inner lens. It is assumed that an inorganic film is provided on at least one of the rear surface side of the outer lens and the front surface side of the inner lens (Patent Documents 3 and 4).

However, in the goggles described in the above-mentioned Patent Document 1, since the lens itself is provided with a vent hole, there is a problem that the strength of the lens is lowered and the durability is poor, and the vent hole is covered with a covering member. As a result, there is a problem that the visibility is hindered by the covering member.

  Furthermore, in the goggles described in Patent Document 2, a wide field of view can be secured without increasing the size of the frame, and the inflow amount of air from the ventilation section can be easily changed. However, the ventilation of the frame is still insufficient and sufficient anti-fogging properties cannot be secured.

  Further, even the goggles described in Patent Documents 3 and 4 have a problem that sufficient antifogging properties cannot be ensured only by preventing the fogging of the lens by the antifogging coating.
