摘要： 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.

The rear wheel assembly and the front wheel assembly include 24 inch (ISO 507 mm) or larger wheels. Pedals of the dual drive and steering assembly extend laterally exterior from drive links of the dual drive and steering assembly so that feet of the rider straddle the left and right drive link. A steering train of the dual drive and steering assembly is configured so that the front wheel assembly turns entirely forward of the range of motion of left and right handlebar assemblies of the dual drive and steering assembly.
