GATE ROLLER WITH TAPERED SIDE WALLS AND RELATED METHODS

摘要

A roller facilitates movement of a gate or similar barrier between a first and second position. The barrier fits at least generally within a channel formed at the periphery of the roller, and the channel is shaped to reduce the contact area and resulting friction that can otherwise occur between the confronting surfaces of the channel and the barrier.
