ABSTRACT:
Routine hand-labor cargo processing is an integral component of world commerce. The present invention permits the incorporation in one-and-the-same freight floor surface of the capacity for near-instantaneous conversion from the traditional static norm to the fluidity of an appropriately-spaced roller ball floor surface constructed of a positively unfailing composition. This convertability aspect offers an incomparable cost reduction in both labor and equipment in the cargo handling field. This floor system allows for those transfer balls 20 to retract from and project above its floor surface at the will of the operator. In the optimum embodiment, a lattice-like interconnection of reciprocally sliding structural angles 24 mounted with a plurality of appropriately spaced elevating wedges 22 upon which hinge plate 16 lift wheels (ball bearings) 30 ascend and decend to swing the hinge plates 16 up and down, thus correspondingly projecting and retracting an equal number of mounted transfer balls 20 thru the floor level.
