A dual position hand truck includes a central frame having two side rails and a toe plate. Positioned at an upper end of the central frame is a U-shaped handle bar which has a hand gripping portion and two extended legs with castered wheels attached at their respective bottom ends. The handle bar is pivotally attached to the frame by a fixed shaft and a pair of support brackets. The support brackets also allow the extended legs to slide along their length. Attached to the support brackets is a spring biased locking bar which locks the handle bar against rotational movement relative to the frame.

[ What is claimed is:] [1.]1. A dual position hand truck which converts from a two-wheeled version to a four-wheeled platform truck comprising:a pair of side rails having upper and lower ends joined by cross rails along their length and a toe plate for load supporting in the two wheel configuration joining the lower ends of the side rails;an axle supporting a pair of wheels attached at the lower end of the side rails;a U-shaped handle bar having a pair of extended parallel legs pivotally attached to the side rails at their upper ends;a pair of castered wheels mounted on the ends of said legs for use in the four-wheeled platform version;a pair of support brackets each bracket being pivotally mounted on a side rail, each bracket supporting one of said legs for sliding movement therein and rotational movement relative to the side rails;at least one latch plate mounted on one of said rails having at least two latching positions for rotational locking of said legs;a locking bar rotatably mounted on said support bracket for engaging the two latching positions on the latch plate and locking the legs of the handle bar in at least two angular positions;at least one locking pin mounted on said support bracket for engaging one of said legs and preventing the handle bar from sliding movement in the support bracket, the locking pin being actuated by movement of said locking bar.
