Abstract
A three-wheeled roller skate and method therefore, comprising a substantially shoe-shaped foot receptacle, two heel end wheels rotatably coupled to an axis, and a toe end wheel smaller in diameter than the two heel end wheels and positioned in front of and spaced apart from the toe end of the skater's foot, allowing a user to maximize both stability as well as speed.
Claims4
A three wheel roller skate comprising, in combination:
- a 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 platform with said heel end of said foot receptacle coupled proximate said first end of said platform and said toe end of said foot receptacle coupled proximate said second end of said platform;
- an axle having a first end and a second end, said axle is fixedly coupled to said bottom portion of said platform proximate a center of gravity of said shoe-shaped foot receptacle below and closer to said front portion than said rear portion of said foot receptacle;
- a first wheel rotatably coupled to said first end of said axle proximate said first side of said 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 platform and substantially parallel to said first wheel;
- a third wheel smaller in diameter than said first and second wheels rotatably coupled proximate said second end of said platform, said third wheel is 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 ground during use of the three wheel roller skate;
- and
- a braking device fixedly coupled to said bottom portion of said platform proximate said first end.

A method of forming a three wheel skate, comprising, in combination the steps of:
- providing a 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:
- providing 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 platform with said heel end of said foot receptacle coupled proximate said first end of said platform and said toe end of said foot receptacle coupled proximate said second end of said platform;
- providing an axle having a first end and a second end, said axle is fixedly coupled to said bottom portion of said platform proximate a center of gravity of said shoe-shaped foot receptacle below and closer to said front portion than said rear portion of said shoe-shaped foot receptacle;
- rotatable coupling a first wheel to said first end of said axle proximate said first side of said platform;
- rotatably coupling a second wheel having substantially the same shape and diameter of said first wheel to said second end of said axle proximate said second side of said platform and substantially parallel to said first wheel;
- rotatably coupling a third wheel smaller in diameter than said first and second wheels proximate said second end of said platform, said third wheel is 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 ground during use of the three wheel roller skate;
- and
- fixedly coupled a braking device to said bottom portion of said platform proximate said first end.
