Abstract
A turntable in modular pie or other sections, which sections can be added or taken away in concentric rings from a base version of the turntable in order to scale the size and capacity of that turntable to accommodate a wide range of size and loading needs.
Claims15
A method of assembling a turntable comprising:
- providing a hub defining a first rotation axis;
- providing a base including a plurality of rolling supports that each rotate about one of a plurality of axes of rotation perpendicular to said first rotation axis, said base including a plurality of base sections;
- securing a rotating member to said hub such that a center of said rotating member aligns with the first rotation axis, said rotating member including a plurality of sections;
- positioning a first one of said plurality of base sections radially around said hub, the first one of said plurality of base sections including a first set of the plurality of rolling supports;
- coupling a first one of said plurality of sections to the hub that defines a center of said rotating member, said first one of said plurality of sections supported by the first set of the plurality of rolling supports and defining a first radius;
- securing a second one of said plurality of base sections radially outwards of said first base section, said second one of said plurality of base sections including a second set of the plurality of rolling supports;
- and
- securing a second section around said first section and supported at least in part by said second set of the plurality of rollers to define a second radius greater than the first radius.

A turntable comprising:
- a hub defining an axis;
- a first section having an outer edge and a center aligned with the axis, said first section affixed to said hub;
- a second section having an inner edge, the inner edge configured to fit around the outer edge of said first section, said second section removably secured to said first section such that said first and second sections are rotatable about said axis;
- and
- rollers positioned below a bottom surface of said first and second sections, said rollers supporting said first and second sections to enable rotation about said hub axis.
