Abstract: There is disclosed a weight transfer roller apparatus including a barrel type housing formed on one extremity with a radially inwardly projecting retaining flange forming a circular protrusion opening. A roller ball is received within the bore of such barrel, has one side projecting from such opening, and has its opposite side nested on an annular high lubricity plastic ring formed with a bearing seat defining a sector of a sphere corresponding with the spherical roller. The annular bearing ring rests on a retainer secured to such housing whereby the housing may be mounted in a weight transfer platform and loads passing thereover will weight downwardly on such ball to be carried by the bearing ring. Preferably, the ball, annular bearing ring, and retainer are telescopically received in the bore of the barrel with the retainer being selectively removable for removal of the bearing and ball for replacement thereof upon deterioration or damage.

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.
