Abstract

Abstract Means for supporting a writing board, overhead screen, notice board or the like, including a pair of upper arms carried by the article with notches or recesses opening downwardly thereon for riding on one of, preferably, a plurality of rails of a horizontally fixed fitting, with a pair of lower arms fastened to the article and adapted to lean against a fixed wall below the horizontal fitting. Preferably, the upper arms are pivotable about a horizontal axis to permit inclination of the article relative to the fitting. A second rail can be provided to carry an additional article with shorter supporting arms, so that one article can be displaced laterally relative to the other without being taken down from the fitting.
