Abstract
A pair of variably adjustable lower body supports such as footnests or legrests are adapted to be mounted on a wheel chair. Each support is mounted on one of two tubular receptacles on the front of the frame of the wheel chair. The support includes four elongated structural members and a planar footplate. Each of the structural members are sequentially linked together by a releasable rotary connection. The releasable rotary is formed by a splined shaft attached to one structural member and a splined sleeve attached to the next structural member. A releasable fastening device is used to hold the splined sleeve onto the splined shaft so that the sleeve can be selectively rotated relative to the shaft angular of the support and footplate relative to the wheel chair frame.
