Abstract:
1. A limb support device comprising: a vertical support; a base connected to a lower end of the vertical support; and a head portion connected to an upper end of the vertical support; wherein the base includes at least three foldable legs which can be positioned in either a first position in which each of the at least three foldable legs extends in a perpendicular direction from a longitudinal axis of the vertical support or a second position in which each of the at least three foldable legs extends parallel to the longitudinal axis of the vertical support; wherein the head portion includes a upward-facing concave saddle, and wherein the head portion is pivotally connected to the vertical support and is thereby capable of being positioned at a variable angle with respect to the longitudinal axis of the vertical support; and wherein the vertical support has a length which is continuously variable, wherein the vertical support has a sleeve member that includes internal helical threads and an inner member that includes external helical threads, wherein the external helical threads of the inner member engage the internal helical threads of the sleeve member to secure the inner member in position within the sleeve member, wherein the inner member comprises a pair of locking blocks having outward-facing threads to facilitate engagement with the internal helical threads of the sleeve member, wherein the pair of locking blocks are positioned within a carrier and move radially inward or outward through openings on opposite sides of the carrier to alternately engage with and disengage from the internal helical threads of the sleeve member.
