Abstract

A foldable parallel bar apparatus includes generally U-shaped first and second end frames and a set of handrails connected to and extending between the first and second end frames, wherein the handrails are foldable so as to move the first and second end frames closer to one another thereby compacting the apparatus. When multiple modules of the end frames are connected, they provide an uninterrupted path between the handrails. An alternative embodiment provides base platforms that are foldable relative to each other and handrails that are vertically and horizontally adjustable.
