  • Patent number: 4893824
    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.
