Abstract
In the present invention, there is provided an ice skateboard comprising a bottom surface and trucks and axles mounted to the bottom surface. A set of runners is pivotally mounted to the axles. Each of the runners has a solid body, a bearing assembly, a metal blade mounted to the solid body and a centre of gravity between the bearing assembly and the metal blade.
The maximum radial dimension of the runner about the bearing assembly is shorter than the distance of the axle from the bottom surface of the skateboard such that each runner is free to rotate about one of the axles to recede against the board. In another aspect, the metal blade of each runner is mounted in a slot and a cushion strip is mounted between the metal blade and the bottom surface of the slot for absorbing a vertical movement of the blade. The movements of the metal blade on a rough ice surface is partly absorbed by the cushion strip and only partly transmitted to the solid body, to the trucks and to the bottom surface of the ice skateboard.

In another aspect, the metal blade of each runner is mounted in a slot and a cushion strip is mounted between the metal blade and the bottom surface of the slot for absorbing a vertical movement of the blade. The movements of the metal blade on a rough ice surface is partly absorbed by the cushion strip and only partly transmitted to the solid body, to the trucks and to the bottom surface of the ice skateboard.

such that each of said skateboard runners is free to rotate half a turn about one of said axles when said ice skateboard is overturned.
2. The ice skateboard as claimed in claim 1, wherein said upper portion of said solid body of said skateboard runner is covered with a layer of soft padding material.
3. The ice skateboard as claimed in claim 2, wherein said metal blade of said skateboard runner has a length of about 2-1/5 inches.
4. The ice skateboard as claimed in claim 1, wherein said solid body of said skateboard runner has a slot in said lower portion thereof, said skateboard runner further has a cushion strip mounted inside said slot against a bottom surface of said slot, and said metal blade is mounted in said slot against said cushion strip.
5. The ice skateboard as claimed in claim 4, wherein said metal blade of said skateboard runner has two humps thereon, said slot has two rounded cavities therein around said humps, and said cushion strip is a contoured strip disposed between said humps and said rounded cavities.
6. The ice skateboard as claimed in claim 5, wherein said metal blade of said skateboard runner further has a hole in each of said humps, said metal blade being retained to said solid body by bolts respectively extending through one of said holes, and said skateboard runner further comprises a cushion washer disposed inside each of said holes and around each of said bolts.
7. The ice skateboard as claimed in claim 4, wherein said slot in said solid body of said skateboard runner has two closed end walls tightly enclosing said metal blade in a longitudinal direction of said skateboard runner.
8. The ice skateboard as claimed in claim 7, wherein said slot in said solid body of said skateboard runner has a width being a precise sliding fit over a thickness of said metal blade.
9. The ice skateboard as claimed in claim 5, wherein said metal blade of said skateboard runner further has a keyhole in each of said humps, said metal blade being retained to said solid body by bolts respectively extending from one of said keyholes, through said solid body, to said upper portion of said solid body.
10. The ice skateboard as claimed in claim 9, wherein said skateboard runner further comprises a spring and washer assembly mounted on each of said bolts for adjusting a compression of said cushion strip between said bottom wall of said cavity and said metal blade.
11. An ice skateboard comprising:
a bottom surface and trucks and axles mounted to said bottom surface, said axles being at a distance from said bottom surface; and skateboard runners pivotally mounted to said axles; each of said skateboard runners comprising:
