ABSTRACT:
A handcart is constructed to include two main frames having outward expanded shoulder and lower portions, an extension handle assembly, an upper crossbar, a lower crossbar, a carrier, and two wheel holders. The two main frames have two upper ends fixedly received in side holes formed at the upper crossbar and two lower ends pivotally connected to the carrier. The extension handle assembly includes two outer pipes, two inner pipes, and a top handle. The upper crossbar is provided with a mechanism means to control the extension and collapse of the inner pipes from and into the outer pipes. The lower crossbar may, together with a fastening strap, hold the carrier and luggages loaded on the carrier in place. When the carrier is extended to a horizontal position, the two wheel holders are extended outward at the same time, permitting the handcart to conveniently carry and transport luggages or articles. And, when the carrier is folded toward the main frames in a vertical position, the two wheel holders are folded inward at the same time. At this point, the whole handcart in a collapsed state can be tied up with a strap for convenient storage.
