    Abstract: A fastener which is affixed to a wall and on which a panel or other generally flat object is placed and held in position. The fastener has at least one straight and flat edge. The fastener is a device to be used at least in twos. On one fastener rests the panel and the other fastener holds the top of the panel to the wall. The fastener is made up of two interacting pieces (1, 2) of which one, for hanging (1), to be affixed to the wall and the other, for holding in position (2), which can be engaged by or released from the first to fix or release the panel. The first piece (1) has the general shape of an essentially straight angle piece of which one branch (1') is arranged in such a way as to enable it to be fixed to the wall, and the other branch (1") has an aperture (4) through which the second piece (2) can pass the second piece (2) is in the shape of a cross of which one part is longer than the other.

    Abstract: An indicia receiving board, such as a chalkboard, or marker board having a writing surface and a longitudinal folding rail hinged at its ends and projecting forwardly from the bottom of the board. The hinged arrangement provides a rail which may be folded upwardly into close proximity to the plane of the indicia receiving or writing surface and thereby permit the use of a much thinner shipping carton with an appreciably reduced internal packaging support. After a board is removed from its carton, the rail is pivoted about its end hinges to an extended transverse position generally perpendicular to the writing surface of the board and thereby provide a ledge or shelf for chalk, erasers, markers, and/or other indicia affixing and removing articles. The rail is supported in its extended position by substantially coextensive foot means projecting from the inner lower margin of the rail to engage the bottom of the board. One or more angular bracket or clip means are provided intermediate the ends of the rail for fastening said rail to the lower margin of the board to maintain the bearing of the foot member against the bottom of said board.
