Abstract
A frame for luggage includes a plywood floor, a channel-shaped main frame attached to the ends of the floor and projecting therefrom, a pair of A-frame brackets capturing the ends of the floor at their bases and being attached at their apexes to the main frame, a pair of major wheels rotatably mounted on transverse axles fixed to the floor centered longitudinally between the ends of the floor, and a caster wheel mounted to said floor at the each end thereof. The luggage frame is strong, yet lightweight and is supported primarily on the major wheels which being on fixed axles maintain the luggage frame tracking in the direction in which it is pulled while the castered wheels provide low friction ground support for the ends of the floor.
