ABSTRACT:
In a steerable roller skate a one-piece sole plate has a bottom wall, with a pair of support shaft bosses in the bottom wall, each with an open-ended vertical passage. An elongated steel shape having internally threaded bolt-receiving spuds spaced along its length complementarily to the bosses is positioned to be coaxial with the boss openings. Shaft bolts, for mounting wheel trucks, extend through the boss passages and into threaded engagement with the spuds. The underside of the sole plate has a pair of bearing tongue seats formed in it. Neither the shaft bosses nor the seats have a reentrant surface with respect to the adjacent surfaces of the underside of the sole plate.
