ABSTRACT:
A hub assembly comprising a pair of hub members, each having a tubular body or bushing portion which is centrally bored to enable the hub members to be slid onto a shaft or axle of uniform circular cross-section. The hub members are adapted to be disposed on the shaft to support a wheel element, and their tubular bodies are adapted to be interfitted one in the other, thus establishing an annular seat for the wheel element. One of the tubular bodies in insertably slidably received into a substantially large bore of the other tubular body and both tubular bodies are configured such that they bindingly lock to each other and to the shaft as a function of limited manual rotation of one hub member relative to the other. Reverse rotation acts to release the locking action.
