Abstract
Skateboard devices, and methods of riding and steering an elongated foldable skateboard with two large front wheels pivotally attached to the front of the skateboard and a single large rear centered wheel with depressible brake. The skateboard allows for the rider with one foot on the skateboard to propel the skateboard by pushing off the ground with another foot. A stabilizing assembly with angled bolt/pin/rod that inserts into an oblong eyelet opening with pliable bushing on the front axle can allow for the rider to tilt the board with their weight to turn the skateboard to the left or to the right.
Claims8
A three wheel steerable skateboard comprising:
- a deck having a front end and a back end;
- a pair of front wheels;
- a forward off vertical angled pivot mount for pivotally attaching the pair of front wheels to the front end of the deck, wherein steering the skateboard is adapted by a rider tilting the skateboard side-to-side;
- single rear wheel mounted adjacent to the back end of the deck;
- and
- an axle member for attaching the front wheels to one another, and the pivot mount is pivotally attached to the front end of the deck by a single pivot, the pivot mount has:
- a raised eyelet on a middle portion of the axle member, the eyelet having an enlarged opening therethrough;
- and
- a stabilizing member attached to the skateboard having an angled rod with an end protruding through the enlarged opening in the eyelet with a pliable bushing, the enlarged opening having a larger diameter than the diameter of the rod, the opening being large enough to allow for the front wheels on the axle member with attached eyelet to move to the left and to the right, wherein the stabilizing member stabilizes turning motion of the skateboard when the skateboard is tilted to the right or to the left.
