Patent ID: 7874115

Claim:
A modular floor comprising: first and second main beams, each main beam including an upper surface and a side wall, the side wall defining a main beam length and including at least one track structure; a first cross beam; a locking mechanism configured to releasably receive the first main beam and the second main beam in respective locked positions, the locking mechanism further configured to removably receive the first ground-engaging leg, the locking mechanism including a first lock and a second lock oriented to releasably receive the first main beam and the second main beam respectively in abutting registry with the side wall track structure of the first main beam substantially aligned with the side wall track structure of the second main beam when the first main beam and the second main beam are in the locked positions; an attachment bracket configured to operably couple the first cross beam substantially transverse to the first main beam, the attachment bracket slidably receivable by the side wall track structure of the first main beam and the side wall track structure of the second main beam and shiftable along and between the side wall track structure of the first main beam and the side wall track structure of the second main beam when the first main beam and the second main beam are received by the first lock and the second lock of the locking mechanism in the locked positions; and a floor panel having floor coupling structure slidable on the upper surface of the first main beam with respect to the main beam length.
