Abstract
Abstract An in-line roller skate having at least one gyroscopic stabilizer mechanically coupled to at least one wheel of the skate for providing stabilization and improved coasting of the skate. The at least one stabilizer is positioned beneath the boot of the skate proximate the user's longitudinal center of gravity and is coupled to one or more of the wheels by a drive belt. An alternate embodiment of the present invention includes a generator driven by one or more of the skate wheels for supplying electrical power to a plurality of lights on the skate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
A gyroscopic in-line roller skate comprising: a boot having a sole; a wheel support secured to said sole; a plurality of wheels rotatably secured to said wheel support, said plurality of wheels being centered in a common plane; a gyroscopic stabilizer means in mechanical communication with at least one of said plurality of wheels for imparting a gyroscopic resistance to rotational movement of said boot in a predetermined direction, said gyroscopic stabilizer means comprising a gyroscopic stabilizer rotatably coupled to said wheel support, and a pulley belt frictionally engaged to both said gyroscopic stabilizer and one of said plurality of wheels, whereby said at least one gyroscopic stabilizer rotates proportionally with said wheel; a belt frictionally engaged with at least two of said plurality of wheels for engaging a ground surface; at least one light assembly mounted to said boot; and, a generator in mechanical communication with at least one of said plurality of wheels, said generator being electrically connected to said at least one light assembly for providing electrical power thereto.
Claim 2
Dependent Claim
172 words
A gyroscopic in-line roller skate comprising: a boot having a sole; a wheel support secured to said sole; a plurality of wheels rotatably secured to said wheel support, said plurality of wheels being centered in a common plane; a gyroscopic stabilizer means in mechanical communication with at least one of said plurality of wheels for imparting a gyroscopic resistance to rotational movement of said boot in a predetermined direction, said gyroscopic stabilizer means comprising a gyroscopic stabilizer rotatably coupled to said wheel support, and a pulley belt frictionally engaged to both said gyroscopic stabilizer and one of said plurality of wheels, whereby said at least one gyroscopic stabilizer rotates proportionally with said wheel; a belt frictionally engaged with at least two of said plurality of wheels for engaging a ground surface; at least one light assembly mounted to said boot; and, a generator in mechanical communication with at least one of said plurality of wheels, said generator being electrically connected to said at least one light assembly for providing electrical power thereto.
Claim 3
Dependent Claim
44 words
The gyroscopic in-line roller skate of claim 1, and further comprising a brake assembly means secured to said wheel support for selectively decelerating said skate, said brake assembly comprising a brake pad mounted to said wheel support and selectively engagable to said ground surface.
