Abstract
A latch assembly mounted on a two-wheeled hand truck having vertically extending wings mounted on the hand truck frame side rails to pivot about axes extending generally parallel to said side rails from an operative position in which they extend laterally as substantially extensions of said side rails to a folded inoperative inboard transport position in which they lie inboard of the laterally inboard sides of said rails. The latch assembly is mounted on the frame for movement in a lateral path from a first position in which the latch assembly blocks movement of the wings to a laterally displaced second position in which the wings are freed to travel.
