ABSTRACT:
A carrying device is arranged to permit a workman to easily lift and transport large sheets of construction material such as plywood, wallboard and the like. The carrying device has a framework forming upper and lower lifting regions, preferably located to rest upon the shoulder and against the hip. The framework additionally defines a plane against which a sheet of material may be placed, and pivotally supports, adjacent said plane, cam means which are mounted eccentrically, arranged to be gravitationally rotated into gripping engagement with a sheet of material placed against said plane, and arranged to be rotated into tighter gripping engagement by gravitational forces exerted on the sheet of material as the framework is lifted upwardly. Preferably the cam means comprises a pair of cams mounted opposite a pair of tubular frame members defining the plane, the cams being joined for movement in tandem by a connecting rod to facilitate release of the sheet material from the carrier by simply raising the connecting rod. Preferably the framework comprises a substantially vertical U-shaped tubular member joined at its upper ends to a substantially horizontal U-shaped tubular member having downwardly extending mounting arms attached to the cam means. The carrying device is lightweight and inexpensive, and substantially simplifies the task of lifting and transporting a large sheet of construction material.
