Abstract:
A movable workseat cart for supporting heavily loaded buckets, comprising:a unitary body member having a peripheral outer skirt surrounding a central circular receptacle that is configured to receive a bucket having a circular outer wall, said outer skirt and said central receptacle being connected by an integral spanning web having an upper surface and a lower surface with at least portions of said web lying in and defining a common web plane;said central circular receptacle being defined by a peripheral wall having an inner wall portion, an outer wall portion, an upper peripheral edge and a lower peripheral edge, said receptacle being further defined by a bottom structure extending from said inner wall portion proximate said lower peripheral edge, wherein at least portions of said bottom structure lie in and define a common bottom plane positioned in parallel spaced apart relationship to said common web plane;said outer peripheral skirt having an upper skirt edge, a lower skirt edge, an inner skirt portion and an outer skirt portion, wherein at least portions of said lower skirt edge lie in and define a common skirt edge plane;said integral spanning web extending from the said inner skirt portion intermediate said upper skirt edge and said lower skirt edge such that said skirt forms an outer containment wall surrounding said spanning web, extending both above and below said web; andsaid common skirt edge plane and said common bottom plane being disposed in substantially parallel relationship proximate each other, neither said common skirt edge plane nor said common bottom plane being disposed less than a given distance from said common web plane when said given distance is measured in a direction substantially normal to said common planes;at least three swivel-mount wheels of given radius coupled to said integral spanning web proximate said lower surface thereof at equally spaced intervals around said central circular receptacle, said swivel-mount wheels together defining a common wheel plane tangent to each wheel at a point most remote from said spanning web, said common wheel plane being spaced from said common web plane a predetermined distance greater than said given distance, such that the distance between said common wheel plane and each of said common skirt plane and said common bottom plane is not substantially greater than said given radius of said wheels.
