This disclosure describes a work site utility carrier that configures into a dolly and hand truck in its retracted mode and a work bench in its elevated mode. A lower receptacle formed as part of a chassis with wheels, and an upper receptacle are pivotally connected by a unique positioning apparatus. In a retracted position the two receptacles lie side-by-side with their top surfaces essentially planar. In this mode, the carrier serves as a dolly or a hand truck. In the elevated mode the second receptacle pivots up to station securely above the chassis, ...
The invention claimed is: 1. A work site utility carrier comprising: a first structure comprising a first top surface; a second structure comprising a second top surface; means for pivotally mounting said second structure in an elevated position above said first structure and for maintaining parallel relation at all times between said first and said second top surfaces; means for positioning said first and said second structures in a retracted position in which said first and said second top surfaces are substantially co-planar; a chassis for mounting s...
