发明名称 Dolly having multiple supports hingedly joined together
摘要 A dolly for transporting multiple containers. The dolly is provided with a plurality of casters which allow it to spin on its footprint. Supports, each of which can carry a container, are hinged together allowing the dolly to flex when encountering alterations in flooring level. Also provided are large side wheels which reduce the force necessary to push the dolly over a bump or onto a floor which is at a higher elevation. When one support is not carrying a container, the support can be rotated with the hinge to a point at which it is approximately perpendicular to the adjacent support and thereby approximately vertical to the floor. Rotating one support to an approximately vertical position shortens the dolly footprint and aids in storage. Moreover, a support which is rotated to an approximately vertical position can be temporarily maintained in that position by a lock.
