Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A support frame assembly having a pair of vertically extending corner posts interconnected by a transverse cross bar at each end of the support frame and rails extending between the ends of the frames, means for connecting the rail, cross bar, and corner post at each corner of the frame, said means comprising: an integral upper terminal portion of the corner post having a rail engaging portion, said rail engaging portion being of generally U-shaped configuration opening upwardly for reception of a portion of the length of the rail; linkage means interconnecting the terminal sections of the cross bar and the corner post in superposed adjacent relation; and a locking arm mounted for movement between an opened and closed position over said rail engaging portion of the corner post, said arm having an end provided with a camming surface to cammingly engage the upper surface of a portion of an associated rail disposed within the rail engaging portion of said upper terminal portion of the corner post, thereby effectively preventing relative movement between the frame and the rail.
