Abstract
Abstract The pallet construction comprises a single platform supported on spaced molded plastic pallet feet mechanically secured to the platform. Each pallet foot consists of two separate components adapted for packing and shipping comprising: (1) a circular tapered cup portion having a flange extending outside of the cup; and (2) an open circular locking ring consisting of a flange of the same size as that on the cup with a downwardly depending body portion rim which extends into the cup and which has a locking means cooperating with the locking means inside the cup. A variation utilizes means for attaching a second board or runner to the bottom of the pallet feet by having holes in the bottom of the feet with matching holes in the bottom board or runner, and using retaining fasteners therethrough.
