Abstract
A stowable crutch is disclosed which includes two parallel integrated tubes in a single body with a first tube to which a crutch tip is mounted and a second tube to which a rest support is attached, each slidably mounted within an integrated tube. The interior of the integrated tubes are fluted or polygonal in cross section to engage a ratchet or detent mounted on the end of the first and second tubes to effectuate a selection means. The first and second tubes are engaged by an external detent mounted at either end of the body. The first and second tubes are rotated individually to a desired selection and extended to that length whereupon they engage with the external detent. The handgrip is slidably mounted to the body to provide a wide range of adjustment. The external detents provide a means to signal when the first and second tubes are not securely engaged.
