Abstract Ski goggles are composed of goggle frame, goggle lens and rubber band. Vent holes are formed, respectively, in the top peripheral wall portion and the bottom peripheral wall portion of the goggle frame. A permeable coating material is engaged to cover the vent holes. A mounting stand, which serves as duct, is engaged in the central portion of the top peripheral wall portion of the goggle frame. A ventilating fan and a small-size motor for driving the fan are mounted on the mounting stand. The ventilating fan is adapted to compulsorily ventilate the air within the inner space formed between the goggle lens and the face, and is accommodated within the mounting stand. The motor can be turned on or off by a power supply switch. The number of the revolutions can be controlled by the controlling circuit or can be controlled by a controlling circuit or in accordance with the humidity of the inner space.
A sport goggle comprising: a frame of relatively flexible substantially impervious material having an inner edge adapted to contact the face of the wearer and an outer edge in which a lens is mounted, said frame being formed with a plurality of vent holes in its periphery and an opening in its upper portion, said frame and lens forming an inner space about said wearer's face; a mounting stand of relatively rigid material formed with a ventilating opening in its lower portion and an outwardly flared opening in its upper portion, said mounting stand being detachably positioned with its open upper portion in said opening of said frame and projecting into said inner space to form a duct between said inner space and said opening of said frame and a fan disposed within said mounting stand adjacent to said ventilating opening, whereby operation of said fan will forceably withdraw air from said inner space through said ventilating opening and said duct and thereby cause fresh air to be drawn into said inner space through said vent holes.
