Patent attributes
A pull-out display shelf assembly having spaced-apart support structures mounted on gondola uprights, for example, and supporting a display shelf for movement between fully retracted and extended positions, with locking means for securing the shelf structure in any set position. The locking mechanism includes vertically rotatable square locking bars freely movable in a locking track when aligned therewith, and having locking engagement with the track when rotated out of alignment with the track. Simplified and improved support structures are formed of heavy gauge sheet metal, bent into an L-shaped configuration for strength and rigidity and formed to provide elongated locking slots in horizontal bottom panels of the L-shaped supports. Component parts are minimized and rigidity and locking action are improved. Stabilizing tabs at the inner ends of the support brackets minimize lateral flexing of the brackets when the shelf is released for movement relative to the support brackets.
