Abstract:
1. An interlocking floor assembly comprising: a plurality of floor modules, each floor module having a square floor surface and four rectangular, vertical walls projecting downward from the bottom of said floor surface, the floor surface and vertical walls arranged to form a right rectangular-sided prism with an open base, each floor module including a hollow cylindrical load member that extends downward from the center of the floor surface and a plurality of cylindrical projections that extend downward from the bottom of the floor surface, the plurality of cylindrical projections positioned on a plurality of line segments running from the center of the floor surface to a mid-point of the edges of the square floor surface, with a first section of each cylindrical projection and a second section of each cylindrical projection having a greater diameter than the first section; a plurality of floor connectors, each floor connector having four perpendicular arms arranged in an X-shape, with each arm having a base and two walls forming a U-shaped cross section, the arms adapted to receive and retain the vertical walls of the floor modules, the walls of each arm being turned slightly inward to form an opening that is narrower at the top of each arm than at the bottom, a first pair of the perpendicular arms each having a recessed distal section on the exterior wall and base surfaces of the arm, and a second pair of the perpendicular arms each having a recessed distal section on the interior wall and base surfaces of the arm, the second pair of perpendicular arms each comprising a pair of cylindrical sleeves located on the exterior wall surfaces of the arm; wherein the distal section of the second pair of perpendicular arms of each floor connector is adapted to receive the distal section of the first pair of perpendicular arms of an adjacent floor connector, and, when the first and second pairs of arms are engaged the distance between adjacent floor connectors is about the length of a side of the floor surface; and wherein the cylindrical sleeves of the floor connectors are adapted to engage the cylindrical projections of the floor modules, with the first section of the cylindrical projections adapted to be inserted into the cylindrical sleeves and the second section of the cylindrical projections adapted to rest on a top of the cylindrical sleeves.
