A folding hand truck with a four-part handle shaft 1, in which a bottom part 6 and a central part 8 are connected by an articulation 7, while a locking part 9, to which a handle part 11 is articulated by a multiple articulation 10 is guided telescopically in these two parts, so that in the telescope
A folding hand truck with a four-part handle shaft 1, in which a bottom part 6 and a central part 8 are connected by an articulation 7, while a locking part 9, to which a handle part 11 is articulated by a multiple articulation 10 is guided telescopically in these two parts, so that in the telescoped state of the handle part the multiple articulation assumes a position above the articulation (FIG. 1).

A simplified hand truck having a wheeled horizontal carrier part (2) foldably connected to a collapsible upright handle portion (1) wherein, in accordance with the invention, said upright handle portion (1) comprises two pairs of interarticulated, generally rectangular, planar frame sections, one (6, 8) of said pairs being stationary with respect to the wheels and the other (9, 11) of said pairs being slidable, within guide means (13, 14) provided on the stationary one (6, 8) of said pairs, between a retracted position and an extended position; each of said pairs being internally hinged along adjacent edges of said frame sections by a respective hinge means (7, 10) to permit the frame sections defining a pair to rotate with respect to each other, with the four frame sections being so dimensioned that said two hing means (7, 10) are aligned with each other when said slidable pair (9, 11) is in said retracted position, thereby permitting collapse of said upright handle portion (1) by a single folding operation; said slidable pair (9, 11), when in its extended position, locking the hinge means (7) of said stationary pair against relative rotation of the frame sections (6, 8) thereof, said two hinge means (7, 10) then being out of alignment with each other; and the overall length of said upright handle portion (1) being less when said slidable (9, 11) section pair is retracted than when said slidable pair is extended and serving as a locking element.
