1. A roller skate comprising:
- (a) a shoe for receiving therein a person'"'"'s foot, said shoe having a bottom sole,(b) a frame fixedly attached to said bottom sole, a front wheel rotatably supported by a brace means depending from said frame adjacent to and beneath the toe of said shoe, a rear wheel rotatably supported by a brace means depending from said frame adjacent to and beneath the heel of said shoe,(c) a pair of center wheels rotatably supported on a common axis by a brace depending from said frame at a central location on said frame so that said common axis is substantially equidistant from the axes of rotation of said front and rear wheels, all of said wheels being of the same size and at the same elevation for simultaneous rolling contact with a support surface, said front and rear wheels being aligned with one another so as to be rotatable at a location along an imaginary center line of said sole, said center wheels being at opposite sides of said imaginary center line and beneath said sole,(d) a first shock absorber for said center wheels, a second shock absorber for said front wheel, and a third shock absorber for said rear wheel, means coupling said shock absorbers to said frame, said second shock absorber being rearwardly of the axle for the front wheel, said third shock absorber being forwardly of the axle for the rear wheel, a front fork extending from the front axle to said second shock absorber, a rear fork extending from said third shock absorber to the rear wheel axle.

Abstract
The roller skate is designed for outdoor skating with balancing control being attained by a pair of center wheels, a front wheel and a rear wheel. Center wheels are on opposite sides of an imaginary center line while the front and rear wheels are aligned with each other along said imaginary line. All wheels are of the same size. A discrete shock absorber is provided for each of the front and rear wheels with a common shock absorber being provided for the center wheels.

- 6. A roller skate comprising a shoe, a single front wheel rotatably supported beneath and spaced from the toe of the shoe, a single rear wheel rotatably supported beneath and spaced from the heel of the shoe, a pair of center wheels rotatably supported and spaced from the arch of the shoe, the center wheels being on a common axle spaced substantially equidistant from the axes of rotation of front and rear wheels, all of said wheels being of the same size and at the same elevation for simultaneous rolling contact with a surface, the front and rear wheels being aligned with one another so as to be rotatable at a location along an imaginary center line of the sole of the shoe, said center wheels being on opposite sides of said imaginary center line adjacent the side edges of the sole of said shoe, shock absorber means for said wheels including a discrete shock absorber for each of the front and rear wheels and a common shock absorber for the center wheels, means connecting the axle for the front wheel and its shock absorber to the shoe at a location rearwardly of a vertical plane containing the axis of rotation of the front wheel, and means connecting the axle for the rear wheel and its shock absorber to the shoe at a location forwardly of a vertical plane containing the axis of rotation of the rear wheel.
