Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 201 words
An improved ski goggles which comprises: (a) a frame having a front surface containing a plurality of vent holes, said vent holes being disposed on said front surface of said frame and in line with the direction of travel of the skier so the the motion of the skier causes forced ventilation allowing air to more readily enter the goggles, said frame worn on a face in front of the eyes of the skier; (b) a lens supported in said frame to protect the eyes said lens being connected directly to said frame; (c) a fine resistance wire grid extending across said lens; (d) a power source electrically connected to said resistance wire grid for supplying electricity thereto so that enough heat to remove frost and fog from said lens is produced; and (e) a switch connected between said power source and said resistance wire to turn the supply of electricity on and off when so desired by the skier, said power source and said switch forming an integral unit disposed on said frame, so that said power source and said switch form a compact integral unit that is not bulky and does not interfere with the ears of the skier.
Claim 2
Dependent Claim 201 words
An improved ski goggles which comprises: (a) a frame having a front surface containing a plurality of vent holes, said vent holes being disposed on said front surface of said frame and in line with the direction of travel of the skier so the the motion of the skier causes forced ventilation allowing air to more readily enter the goggles, said frame worn on a face in front of the eyes of the skier; (b) a lens supported in said frame to protect the eyes said lens being connected directly to said frame; (c) a fine resistance wire grid extending across said lens; (d) a power source electrically connected to said resistance wire grid for supplying electricity thereto so that enough heat to remove frost and fog from said lens is produced; and (e) a switch connected between said power source and said resistance wire to turn the supply of electricity on and off when so desired by the skier, said power source and said switch forming an integral unit disposed on said frame, so that said power source and said switch form a compact integral unit that is not bulky and does not interfere with the ears of the skier.
Claim 3
Dependent Claim 16 words
An improved ski goggles as recited in claim 1, wherein said power source is a battery.
Claim 4
Dependent Claim 20 words
An improved ski goggles as recited in claim 2, wherein said battery and said switch are disposed within a housing.
Claim 5
Dependent Claim 20 words
An improved ski goggles as recited in claim 3, wherein said housing is mounted on either side of said frame.
Claim 6
Dependent Claim 35 words
An improved ski goggles as recited in claim 3, wherein said housing is mounted on belt of the skier with an elongated expansion cord extending between said housing and said heat generating resistance wire grid.
Claim 7
Dependent Claim 25 words
An improved ski goggles as recited in claim 3, wherein said heat generating resistance wire grid is laminated between two transparent layers of said lens.
Claim 8
Dependent Claim 25 words
An improved ski goggles as recited in claim 3, wherein said heat generating resistance wire grid is embedded between two transparent layers of said lens.
Claim 9
Dependent Claim 26 words
An improved ski goggles as recited in claim 3, wherein said heat generating resistance wire grid is otherwise affixed between two transparent layers of said lens.
Claim 10
Dependent Claim 24 words
An improved ski goggles as recited in claim 3, wherein said heat generating resistance wire grid is attached to inner surface of said lens.
Claim 11
Dependent Claim 24 words
An improved ski goggles as recited in claim 3, wherein said heat generating resistance wire grid is attached to outer surface of said lens.
