Abstract
An improved crutch made up of three sections which quickly assemble and disassemble and adjust handle height using no nuts and bolts. The middle portion between the upper underarm support and the lower ground contact portions, has a pair of cross bars, the upper movable one of which is the handle. A pair of spring-loaded telescoping members mounts the handle on the lower fixed cross bar. Manipulation of the handle and the telescoping members permits one or both of handle height adjustment and/or assembly or disassembly in a single operation.
