Powered roller skates

A skate comprising a base plate, drive wheels carried by said base plate, a platform plate pivotally connected to said base plate, a motor having a housing with external threads, and a collar having threads engaging said threads of said housing, said motor when powered in one direction rotating said wheels and when powered in the other direction rotating to move said collar relative to said housing so that said platform plate may pivot relative to said base plate.

A skate comprising a base plate, a drive shaft, drive wheels carried by said drive shaft, a platform plate pivotally connected to said base plate, a motor having a threaded shaft, and a gear on said drive shaft engaging said threaded shaft, said drive shaft being journalled in unidirectional bearings allowing said drive shaft to turn in one direction to rotate said wheels when said motor is activated in one direction and when said motor is activated in the other direction, said platform plate is pivoted relative to said base plate.

A skate comprising a base plate, a drive shaft, drive wheels carried by said drive shaft, a platform plate pivotally connected to said base plate, an aperture in said base plate, a pad on said platform plate, a motor having a housing with external threads and having a threaded shaft, a collar having threads engaging said threads of said housing, and a gear on said drive shaft engaging said threaded shaft of said motor, said drive shaft being journalled in unidirectional bearings allowing said drive shaft to turn in one direction to rotate said wheels when said motor is activated in the one direction, and when said motor is activated in the other direction said collar moves relative to said housing so that said platform plate may pivot relative to said base plate so that said pad extends through said aperture when said platform plate is adjacent to said base plate.
