Abstract
A multi-purpose luggage cart (10) is disclosed. The cart includes first and second primary support wheels (24a) and (24b) coaxially mounted to a lower frame (11) adjacent the trailing end (11a) and at oppositely disposed sides. A caster (25) is rotatable about a vertical axis (28) and is mounted to the lower frame (11) along its longitudinal axis (12) and adjacent the forward end (11b), wherein the primary support wheels (24a) and (24b) and the caster (25) movably support the lower frame and cart on a floor surface. An upper frame portion (40) includes a cross bar (43), a longitudinal bar portion (44) and a handle portion (45). A step support member (33) is cooperatively connected to the lower frame (11) proximate the forward end (11b) in order to stabilize the cart (10) and prevent movement of the cart (10) when it is positioned upon an escalator.
