Transport system

摘要

The apparatuses and methods disclosed herein may be pushed by hand or pulled by a motor vehicle. Thus, implementations of the transport device disclosed herein may have functions akin to a wheelbarrow or a dumping trailer yet may provide easier and/or more efficient transportation and dumping functions over prior art wheelbarrows and dumping trailers. Implementation of the transport device disclosed herein also may be easier to push over an elevation or up a hill. Furthermore, in some implementations, the transport device disclosed herein includes four wheels and therefore can function like a cart. Still further, in some implementations, the transport device disclosed herein can have the functions of a wagon. In some implementations, the transport device includes a work bench.

1. A transport device consisting of a pair of longitudinal frame supports to support a tub; wherein the frame supports are attached to a bottom of the tub; the frame supports (load arms) are also hinged-attached to two leaver arms that provide the force to form two, second-order-lift mechanisms with the axles of the front wheels acting as fulcrums; located behind and attached to the second-order-lift, the lever arms at the same time act as load arms for a first-order-lift for which the axles of two back wheels act as fulcrums and a pair of handles act as the lever arms; the load arms extend past the axles of the back wheels to act as load arms for two more, first-order-lift mechanisms in which the ends of the load arms act as fulcrums and are brace attached to the handles which act as lever arms for the third pair of first-order-lift mechanisms; wherein the dumping assembly is configured to pivot the frame supports upward and over to dump the contents of the tub as the handles are continuously first pulled down and then pushed down.
