Document filing apparatus

Apparatus for converting a container such as a drawer into a document filing space comprising a pair of rails each rail for attachment on a horizontal edge of a vertical panel such as the side wall of a cabinet drawer so as to receive an end of a tab having a recess extending upwardly from a horizontal edge surface thereof and spaced from a vertical edge surface thereof, the rail comprising a channel shaped portion having two side walls joined by a web adapted to embrace the said panel edge, whereby the rail is readily mountable on the panel edge, a flange projecting outwardly from one of the said side walls at right angles thereto, an upwardly projecting rib extending lengthwise of the flange which is spaced from the said one side wall, upwardly facing substantially flat surface on the flange located between the rib and the adjacent side wall of the rail and forming a guideway for the said horizontal edge surface of the tab when the recess in the tab is located over the rib and adjustment means on the channel shaped portion of the rail enabling the spacing of the rib from the panel to be adjusted and thereafter clamped in position, and a plurality of tabs each of which is adapted for attachment to a document folder, each tab being formed with two parallel side edges, a horizontal edge surface adjacent each side edge and a recess extending upwardly into each horizontal edge surface and adapted to receive the said rib of a rail so that the tab is slidably engaged thereon with the horizontal edge surface resting on the said guideway of the rail and slidable therealong, the horizontal edge surfaces of each tab comprise the upper edges of a pair of slots in the tab and wherein the width of each slot is such in relation to the dimensions of the rib on each rail that the rib is a force-fit through the slot for location in the recess.
