ABSTRACT:
A handcart has a pair of handle bars (3) extending upwardly from opposite sides of a baggage support (1) having wheels (2). The handle bars are extensible. Each handle bar (3) comprises a lower bar (5) and an upper bar (6) which are telescopically put together. The slide movement between the lower and upper bars (5, 6) is selectively inhibited by engaging pins which in the fully extended state of the handle bars (3), engage respective pawls (18). The engaging pins (17) can be disengaged by treading on a treadle (15), whereby the length of handle bars (3) can be reduced.
