Abstract
Abstract A convertible cart for transporting objects having a frame, a first handle connected to the frame, a second handle connected adjacent an opposite end of the frame, a plurality of wheels attached to the frame. Each of the handles is selectively movable between a first position generally perpendicular to the frame and a second position generally aligned with the frame. The wheels support the frame at a position parallel to the surface on which the wheels are placed. The frame has a longitudinal member extending centrally of the frame. The longitudinal member has an end offset from overlapping relationship with one end of the frame. A snap button is provided within the longitudinal member so as to limit telescoping movement of one portion of the longitudinal member with respect to another portion.
