ABSTRACT:
A hand truck comprising an upright frame having an upper frame section which is telescopingly attached to a lower frame section to permit the height of the frame to be adjusted and clamped into position. A short toe plate extends forwardly from the bottom of the lower frame section, and is slightly narrower than a standard file cabinet. A pair of wheels are conventionally mounted to the rear of the lower frame section. A retaining arm having a hooked end bracket is pivotally and slidably mounted to a crossbar of the upper frame section, such that the retaining arm may be pivoted in a vertical plane generally perpendicular to a plane defined by the front surface of the lower frame section, and slidingly extended forward and retracted backward relative to the crossbar. A spring-loaded clamp assembly serves for pivoting the retaining arm, and for restraining the arm against sliding movement. The upper frame section includes a pair of forwardly extending flanges which may be positioned against the top front of the file cabinet, with the retaining arm extending across the top of the filing cabinet so that the hooked end bracket engages the rear edge thereof. An inverted U-shaped handle bar extends rearward at an angle directly from the top of the upper frame section. The front of the frame sections are padded.
