Abstract
Abstract A novel shelf structure for a display rack. The shelf structure is movable in its support plane between an extended position and a retracted position to vary the shelf area exposed for merchandise support. The shelf structure also is positionable in either a horizontal display position or a rearward tilt display position as selected by the user of the display rack. The shelf itself includes a front section and a rear section, the front section being telescopible into and out of the rear section to establish the desired merchandise support area. Both shelf sections are carried on a pair of arms pivotally connected to opposed side frames of the display rack, the pivot axis of the arms being adjacent the front face of the display rack, to permit positioning of the shelf in either the horizontal or rearward tilt attitudes for merchandise display.
