Abstract
A modified skateboard has runners attached to existing trucks. Top and bottom rails of the runners are jointed and slotted to allow changing runner length upon turning. Mounts are slotted to accommodate varying axle base lengths of skateboard trucks and to permit shifting during turns. Right and left turns are achieved by shifting weight from side to side and shortening the runners and sliding the runners relative to the trucks. Runners are braced to keep rails perpendicular to the top of the board.
Claims22
A recreational device comprising
- a skateboard
- trucks affixed to an underside of the skateboard having horizontal axles,
- said trucks comprising forward and rearward pivoting mounts positioned in tandem to each other and near a front of the skateboard and near a rear of the skateboard to enable pivotal steering movement of the axles,
- plural elongated sled runners attached to the trucks in transversely spaced parallel front and rear pairs and means connecting the front and rear elongated sled runners on each side of the skateboard for providing a continuous runner surface and enabling lengthening and shortening of the connected runners when engaged in pivoting movement relative to a longitudinal axis of the skateboard.
A skateboard sled having an elongated board, plural pivoting trucks attached to the board, the trucks including axles mounted for pivoting about axes within the trucks at angles to a longitudinal axis of the elongated board and front and rear pairs of narrow, metal strip runners attached to the axles, and means for connecting the front and rear runners on each of the skateboard sled for providing a continuous runner surface and enabling the connected runners to warp and relatively move and curve and lengthen and shorten during turning of the board.
Elongated sled runners adapted to be attached to the trucks of a skateboard in transversely spaced parallel front and rear pairs, and means connecting the front and rear sled runners on each side of the skateboard for providing a continuous runner surface and enabling lenthening and shortening of the connected runners when engaged in pivoting movement relative to a longitudinal axis of the skateboard, and a central mounting brace attached to the runner and an opening in the mounting brace adapted for receiving a vehicle axle.
The device of cliam 19 wherein
- the connecting means are connected by a pin mounted in a hinge on both front and rear elongated runner sections.
