A hand truck is provided including a forwardly projecting load platform and a generally U-shaped bumper is mounted from the hand truck for pivotal oscillation about a horizontal transverse axis between a lowered position closely overlying and projecting outwardly of the peripheral margins of the load platform and a raised position disposed fully rearward of the front side of the wheeled upstanding frame of the hand truck forwardly of which the load platform projects. The bumper is resilient and therefore prevent injury to objects which would otherwise be damaged or injured as a result of the platform abutting thereagainst and the front side of the upstanding frame of the hand truck defines forwardly opening horizontal recess structure in which the bight portion of the U-shaped bumper is fully recessed when the bumper is in the raised position thereof.

A hand truck including an upstanding frame having front and rear sides and upper and lower ends, a generally horizontal floor surface engageable load platform supported and projecting forwardly from the lower end of said frame, floor engageable wheel means journalled from said frame rearwardly of said platform and about which said frame and platform, as a unit, may be angularly displaced to tilt said frame toward a rearwardly and upwardly inclined position with said platform being forwardly and upwardly inclined and spaced above a horizontal plane containing the lower periphery of said wheel means, the peripheral margin of at least the forward portion of said platform being generally U-shaped in plan, a marginal edge protection bumper for said peripheral margin to prevent the latter from solidly contacting vertically oriented members such as ankles and lower leg portions of adjacent persons and wall surfaces and door jambs when said hand truck is being moved horizontally forwardly over a floor surface when unladen and when said platform is in said rearwardly and upwardly inclined position, said bumper including a generally U-shaped guard incorporating a pair of generally parallel legs and a bight portion extending between and interconnecting one pair of corresponding ends of said legs, means mounting said guard from said frame for oscillation relative thereto about an axis extending between the other pair of corresponding ends of said legs and spaced behind the lower portion of said front side for swinging movement of said guard between a lowered forwardly projecting and generally horizontal position projecting horizontally outwardly of said peripheral margin and a raised position disposed at least substantially entirely behind said front side, said U-shaped guard including padding thereon facing horizontally outward of said peripheral margin when said guard is in said generally horizontal position, said frame including a pair of laterally spaced upright sides, the lower ends of said uprights being received between said other pair of corresponding ends of said legs when said guard is in said lowered position, said opposite side uprights including generally horizontally registered forwardly opening notches formed therein in which said bight portion is recessed rearward of said front side when said guard is in said raised position.
