ABSTRACT:
There is disclosed a skateboard pivot roller assembly including a mounting bracket formed with a generally flat upwardly facing mounting surface for mating with the flat underside of the skateboard platform and is formed in one extremity with a roller housing including a downwardly opening ball socket having a rotatable ball mounted therein and projecting downwardly therefrom to have its lower spherical surface spaced somewhat above the plane of the bottoms of the skateboard wheels. Thus, the skateboard rider can shift his weight to the end of the skateboard having such assembly mounted therebeneath to tilt the skateboard thus lowering such bracket to engage the pivot ball with the ground to enable pivoting and maneuvering of the rider with at least a portion of his weight carried on such ball.
