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
