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 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
327 words
A portable dust pan and refuse container for collecting and transporting refuse material in a disposable open-mouthed, elongated, flexible collection bag comprising: a bag support platform for supporting the bottom of the bag and having a front edge and a rear edge; a front bag support wall and a rear bag support wall respectively connected to the front and rear edges of the bag support platform and extending generally perpendicularly therefrom in spaced apart relation from one another to define lateral side openings through which a bag filled with refuse may be removed therefrom; a bag support chute mounted on the front bag support wall and the rear bag support wall and spaced from the platform at a distance generally equal to the height of the disposable bag; means for releasably securing a bag on the bag support chute with the open-mouth of the bag extended and registered with the bag support chute for entry of refuse material therein; first and second bag restraining means extending respectively between the front bag support wall and the rear bag support wall intermediate the bag support platform and the bag support chute to provide effective lateral side restraint of the bag within the bag nesting area between the front and back bag support walls, at least one of said bag restraining means being releasable to enable subsequent removal of the filled refuse bag through the lateral opening; a pair of spaced ground contacting wheels rotatably mounted on the container about an axis generally adjacent the leading edge of the bag support platform to permit selective rotational repositioning of the container about said axis from a first substantially vertical refuse transporting position to a second substantially horizontal refuse collecting position; and a dust pan carried by the container and projecting outwardly from the bag support chute and operating to abut the ground when the container is in the refuse collecting position whereby refuse material may be swept into the disposable bag.
Claim 2
Dependent Claim
327 words
A portable dust pan and refuse container for collecting and transporting refuse material in a disposable open-mouthed, elongated, flexible collection bag comprising: a bag support platform for supporting the bottom of the bag and having a front edge and a rear edge; a front bag support wall and a rear bag support wall respectively connected to the front and rear edges of the bag support platform and extending generally perpendicularly therefrom in spaced apart relation from one another to define lateral side openings through which a bag filled with refuse may be removed therefrom; a bag support chute mounted on the front bag support wall and the rear bag support wall and spaced from the platform at a distance generally equal to the height of the disposable bag; means for releasably securing a bag on the bag support chute with the open-mouth of the bag extended and registered with the bag support chute for entry of refuse material therein; first and second bag restraining means extending respectively between the front bag support wall and the rear bag support wall intermediate the bag support platform and the bag support chute to provide effective lateral side restraint of the bag within the bag nesting area between the front and back bag support walls, at least one of said bag restraining means being releasable to enable subsequent removal of the filled refuse bag through the lateral opening; a pair of spaced ground contacting wheels rotatably mounted on the container about an axis generally adjacent the leading edge of the bag support platform to permit selective rotational repositioning of the container about said axis from a first substantially vertical refuse transporting position to a second substantially horizontal refuse collecting position; and a dust pan carried by the container and projecting outwardly from the bag support chute and operating to abut the ground when the container is in the refuse collecting position whereby refuse material may be swept into the disposable bag.
Claim 3
Dependent Claim
58 words
The dust pan and refuse container of claim 1, further comprising handle means depending substantially upwardly from the rear bag support wall to facilitate movement of the container when in the substantially vertical refuse transporting position and to facilitate rotational repositioning of the container about the wheel axis between the refuse transporting position and the refuse collecting position.
Claim 4
Dependent Claim
53 words
The dust pan and refuse container of claim 1, further comprising at least one additional wheel rotatably mounted on the container generally adjacent the rear edge of the bag support platform and operative to coact with the pair of wheels to support the container for rolling movement in the vertical refuse transporting position.
Claim 5
Dependent Claim
31 words
The dust pan and refuse container of claim 1, wherein the dust pan defines an elongated ground embracing edge at the outer terminus thereof disposed substantially parallel to the wheel axis.
Claim 6
Dependent Claim
47 words
The dust pan and refuse container of claim 1, wherein the bag restraining means comprises flexible straps at least one of which has a separable buckle whereby at least one of the straps may be separated to release the bag for removal through the lateral side opening.
Claim 7
Dependent Claim
46 words
The dust pan and refuse container of claim 1, wherein said means for releasably securing a bag on the bag support chute is an elastic band which passes around the bag and retains the bag against an increased wall thickness portion of the bag support chute.
Claim 8
Dependent Claim
41 words
The dust pan and refuse container of claim 1, wherein the bag support platform, and the front and rear bag support walls are constructed of a wire mesh material effective to provide a maximum of strength with a minimum of weight.
