ABSTRACT:
A load-carrying device comprises a frame adapted to support a load to be carried, and having front and rear end portions. A wheel is rotatably mounted to the frame and positioned at the front end portion for supporting same. The device of the invention further comprises elongated handle means pivotally connected to the rear end portion and frame support means connected to and displaceable with the handle means, the handle means being pivotally movable between a first position whereat the handle means extends rearwardly of the frame for carrying the load with the frame support means being disposed to support the rear end portion, and a second position whereat the frame support means is retracted from its supporting position. A releasable locking means is also provided for interlocking the handle means with the frame in the first position. Pivotal movement of the handle means from the first to the second position causes the frame to be displaced from a raised position above ground to a lowered position adjacent the ground and the rear end portion of the frame to be disposed substantially on ground level, thereby enabling the load to be loaded or unloaded at ground level.
