ABSTRACT:
A hand truck which may be collapsed by operation of a pivotable support plate and pivotable load bearing side brace members which may be readily detached from the support plate. The hand truck includes a substantially rectangular frame having an upper handle portion, two parallel side portions, and a lower portion. A pair of wheels are rotatably secured in opposed axial alignment on opposite sides of the lower portion of the frame. A support plate pivotably attaches to the lower portion of the frame so that the support plate may pivot about a substantially horizontal axis between a lower horizontally disposed operative position and an upper vertically disposed storage position. A pair of side brace members have lower portions adapted to removably engage the support plate proximate a respective side edge of the support plate and upper portions adapted to pivotably engage a respective parallel side portion of the frame so that each brace member may pivot about a substantially vertical axis between an operative position substantially perpendicular to the frame and a storage position against and substantially parallel to the frame.
