Transport device for wheelless power driven equipment

摘要

A detachable wheeled dolly or hybrid roller skate device for separable connection to the base portion and the handle of relatively large and heavy wheelless power driven handle manipulated machines is disclosed whereby an upward push on lifting the handle tilts the machine from out of surface contact and allows the roller skate device to swing under the machine. A subsequent lowering of the machine allows the roller skate device to support the machine, whereby a downward push on the handle tilts the machine out of surface contact and facilitates transport of the machine from one location to another as required. The centroid or center of mass of the hybrid roller skate device is located so that the roller skate device will swing under the machine to be supported.
