Abstract: A foldable support leg assembly wherein a depending leg is pivotally connected to a pair of fixedly connected bent pair of legs positioned in back-to-back relationship to form a hyperbolic configuration having a pair of upwardly divergent arm portions and a pair of downwardly extending divergent leg portions. The depending leg is pivotal to a stored position into a plane coextensive with the leg portions, and pivotal outwardly to an erected position from the plane to an inclined position. The foldable leg assembly can be employed for supporting a recreational vehicle waste drain hose assembly or a traffic warning signal.
