ABSTRACT:
A horizontal support bar for being interposed between spaced vertical surfaces, such as a doorway jamb, bar support members being located at each bar end, and one of the support members being attached to its associated vertical surface and pivotally connected to the bar wherein the bar may swing to a horizontal self-storing position. The bar length is adjustable and cam wedge surfaces are employed to use vertical forces imposed on the bar to increase the frictional engagement between the support members and the associated supporting surfaces.
