Mobile storage container for traversing walled pathways
View Patent ↗A movable storage container for traversing walled pathways, includes: a) a bin having a bottom and sidewalls and an open top, with an imaginary midline that defines a center with a forward section in front of the midline and an aft section behind the midline; b) at least four ground wheels connected to the bin structure adjacent the bin structure bottom for movement along any surface below the bottom of the bin structure, at least two ground wheels being in the forward section and at least two ground wheels being in the aft section; and c) at least four bumper wheels connected to the bin structure for movement along any surface aside the sidewalls, at least two bumper wheels being in the forward section and at least two bumper wheels being in the aft section.
1. A movable storage container for traversing walled pathways, which compromises:
a) a bin structure having a solid bottom and sidewalls and an open top, said bin structure having an imaginary midline that defines a center, wherein there is a forward section in front of said midline and an aft section behind said midline;
b) at least four ground wheels connected to said bin structure adjacent said bin structure bottom for movement along a surface below said bottom of said bin structure, at least two of said at least four ground wheels being in said forward section and at least two of said four ground wheels being in said aft section, wherein said ground wheels are wheels having a non-vertical axis of rotation within the range of minus 45 degrees to plus 45 degrees from horizontal;
c) at least four bumper wheels connected to said bin structure for movement along any surface aside said sidewalls and extending outwardly beyond said sidewalls, at least two of said at least four bumper wheels being in said forward section and at least two of said four bumper wheels being in said aft section, wherein said bumper wheels are wheels that are angled so that an imaginary line extending perpendicular from the surface below said bottom through the center of each bumper wheel respectively forms an angle of greater than 0 degrees and less than 45 degrees, on either side of the imaginary line, with a line coaxial with a rotational axis of each bumper wheel respectively.
2. The movable storage container of claim 1 wherein said container further includes a cover, and said sidewalls and said cover are solid.
3. The movable storage container of claim 1 wherein said at least four bumper wheels are located above said bin bottom.
4. The movable storage container of claim 1 wherein said ground wheels are caster wheels that rotate on both a vertical axis and a horizontal axis.
5. The movable storage container of claim 1 wherein said ground wheels are wheels having a non-vertical axis of rotation within the range of minus 20 degrees to plus 20 degrees from horizontal.
6. The movable storage container of claim 1 wherein said container has four ground wheels and four bumper wheels.
7. The movable storage container of claim 1 wherein said container is rectangular in shape with four corners and said bumper wheels are located at each of said four corners.
8. The movable storage container of claim 1 wherein said bin structure has a male and a female connector located on opposite sides of said imaginary midline.
9. The movable storage container of claim 1 wherein said container at least four bumper wheels are located above said bin bottom and wherein said ground wheels are caster wheels that rotate on both a vertical axis and a horizontal axis.
