Abstract
Abstract The present specification discloses a combination dust pan and refuse container constructed of inexpensive lightweight materials which is highly transportable and repositionable from an upright refuse transporting position to a horizontal refuse collecting position. The combination dust pan and container is made up of a framework which distends and substantially encloses a conventional disposable trash bag, four circumferentially spaced ground contacting wheels and a dust pan which depends outwardly from the frame near the mouth of the bag. In the transporting position, all four wheels contact the ground and provide a stable base. In the collecting position, the outwardmost edge of the dust pan and two of the wheels which are on a common axle contact the ground. A handle is provided which projects upwardly in both the transporting and collecting positions to facilitate mobility of the pan/container combination. In the preferred embodiment of the invention, mesh type supporting frames are included for heavy duty application and enhanced bag protection. In the alternative embodiment of the invention, the features of a collapsible container and a dimensionally adjustable framework are disclosed.
