A hand truck comprises a frame having upper and lower frame parts which can be pivoted between folded and unfolded positions. Pivotable locks retain the frame parts in both such positions. A pair of wheel braces are attached to the lower frame part for rotation between folded and unfolded positions.

A hand truck comprises a frame having upper and lower frame parts which can be pivoted between folded and unfolded positions. Pivotable locks retain the frame parts in both such positions. A pair of wheel braces are attached to the lower frame part for rotation between folded and unfolded positions. A carrier member is mounted to the lower frame part for rotation between folded and unfolded positions. The carrier member locks the wheel braces in their unfolded positions. The wheel braces carry tires which frictionally engage the carrier member to retain the wheel braces in their folded positions. The portion of the lower frame part which carries the wheel braces and carrier member can be separated from the lower frame part and then rotated ninety degrees before being reattached to the lower frame part in a stored condition.

A hand truck comprising: a frame including a lower frame part, and an upper frame part having a handle and being collapsible toward said lower frame part, a pair of wheel braces pivotably mounted to a bottom portion of said lower frame part for pivotal movement about respective axes between folded and unfolded positions, free ends of said wheel braces carrying ground support wheels, and a carrier member pivotably mounted to said bottom portion of said lower frame part for pivotal movement between folded and unfolded positions, about an axis extending substantially perpendicular to said axes, said wheels including elastomeric tires frictionally engaging portions of said carrier member when said wheel braces and said carrier member are in their folded positions, in order to resist unfolding of said wheel braces.
