Abstract:
A three wheel roller skate comprising, in combination:a horizontal platform having a top portion and a bottom portion and a first end and a second end and a first side and a second side; a substantially shoe-shaped foot receptacle having a heel end and a toe end, said foot receptacle having an upwardly extending foot receiving portion having a front portion and a back portion and is fixedly coupled to said top portion of said horizontal platform with said heel end of said foot receptacle coupled proximate said first end of said horizontal platform and said toe end of said foot receptacle coupled proximate said second end of said horizontal platform, said horizontal platform having a horizontal extension portion extending outwardly from said toe end of said foot receptacle; an axle having a first end and a second end, said axle is fixedly coupled to said bottom portion of said horizontal platform proximate a center of gravity of said shoe-shaped foot receptacle; a first wheel rotatably coupled to said first end of said axle proximate said first side of said horizontal platform; a second wheel having substantially the same shape and diameter of said first wheel rotatably coupled to said second end of said axle proximate said second side of said horizontal platform and substantially parallel to said first wheel; a third wheel smaller in diameter than said first and second wheels rotatably coupled to and below said horizontal extension portion of said horizontal platform proximate said second end of said horizontal platform, said third wheel having an outside diameter substantially equal to a vertical distance defined by the bottom portion of said horizontal platform and a bottom surface portion of either said first wheel or said second wheel, said third wheel having an axle rotatably supported by a pair of vertical members connected to said horizontal extension portion in front of and spaced from said toe end of said shoe receptacle, a bottom surface portion of said third wheel is in horizontal alignment with a bottom surface portion of both said first wheel and said second wheel to maintain said platform parallel to the ground during use of the three wheel roller skates, said third wheel only capable of rotating in a forward and rearward direction; and a braking device fixedly coupled to said bottom portion of said platform proximate said first end.
