1. A portable turntable device for vehicles or the like comprising:
- a substantially circular platform member having;
(i) means for giving a driver of the vehicle or the like notice of being misaligned with said substantially circular platform memer, said means for giving notice to the driver including an integral substantially dome-shaped central portion;
(ii) a table portion for the support of weight extending from the perimeter of said substantially dome-shaped central portion;
(iii) a cantilevered apron portion extending from the perimeter of said substantially flat weight supporting table portion, said cantilevered apron portion constructed and arranged to deflect by an amount sufficient to allow the motor vehicle or the like to be driven onto said weight supporting table portion; and
(iv) an edge wall portion depending downwardly from the perimeter of said cantileverd apron portion; and
means to support said substantially circular platform member located under said substantially circular platform member, said support means having;
(i) at least three substantially vertical load-bearing surfaces in contact with the underside of said weight supporting table portion of said substantially circular platform member, said substantially vertical load-bearing surfaces being rotatable about a substantially horizontal axis; and
(ii) a plurality of substantially horizontal guide surfaces for lateral alignment of said substantially circular platform member, said substantially horiozntal guide surfaces being rotatable about a substantially vertical axis.

Abstract
A portable, sectioned, rotatable platform member has four distinct portions, a central portion, a substantially flat table portion, a curved apron portion, and an edge wall portion. The platform member is supported by vertical rotatable bearing surfaces which are positioned under the substantially flat table portion of the platform member. Additionally, horizontal, rotatable, guide surfaces are located under the platform member to position the platform member and allow for its free rotatability.

9. A portable turntable system comprising:
-
a substantially cicular platform member having; (i) an integral substantially dome-shaped central portion; (ii) a table portion for the support of weight extending from substantially dome-shaped central portion; (iii) a cantilevered apron portion extending from the perimeter of said weight suppoting table portion, said cantilevered apron portion flexing as a cantilevered beam when a heavy object is rolled on or off said substantially circular platform member; and (iv) an edge wall portion extending from said cantilevered apron portion; and means to support said substantially circular platform member located under said substantially circular platform member, said support means having; (i) at least three substantially vertical, load-bearing surfaces in contact with the underside of said weight supporting table portion of said substantially circular platform member; and (ii) a plurality of substantially horizontal guide surfaces in contact with a flange member which depends from the underside of said weight supporting table portion of said substantially circular platform member, said substantially horizontal guide surfaces being rotoatable about a substantially vertical axis. - View Dependent Claims (10)
