Abstract
A steerable roller skate of the shoe skate variety has an elongated one-piece sole plate in the form of an open topped dish with a bottom wall, a side wall and a continuous rim, outturned along the long sides thereof and, in the preferred form, rising from the toe end toward the heel end to join with a heel-less shoe sole uninterruptedly around the sole. A pair of support shaft bosses extend upwardly from the bottom wall, each with an open-ended vertical passage and each crowned with a lip around the passage defining a non-circular socket to receive the head of a bolt-shaft. The underside of the bottom wall 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 bottom wall.
