Independent Claim
196 words
A hand truck comprising a load supporting platform having a top panel, end walls and sidewalls below the top panel, a caster mounted below each corner of the top panel, a substantially rectangular handle at each end of the truck and having laterally spaced legs joined at their ends by upper and lower cross-bars, and means for storing the handles under the platform comprising diametrically opposite upper rails and diametrically opposite lower rails secured to the sidewalls and forming upper and lower channels slidably receiving the lower cross-bars as said handle slide into a stored position, said end walls having longitudinally spaced panels forming a pocket therebetween, an opening through the platform at each corner thereof and a slot in each end wall adjacent said openings, each leg of the handle extending through the opening with said lower cross-bar disposed in said pocket and vertically slidable therein, said openings, slots and pockets cooperating to support said handles in an upright position and to permit pivoting thereof into a position wherein the lower cross-bars are disposed at open ends of said channels for sliding of the handle on the rails into said stored position under the platform.
