发明名称 Rotatable stand
摘要 A freely rotatable, effectively tilt-free stand for carrying plants and the like. The stand includes a plurality of relatively rotatable members cooperatively defining a ball bearing structure wherein the ball bearings are disposed in an annular array at the periphery of the assembly so as to provide an effectively tilt-free rotation thereof. Support of the structure relative to the bearings is effected by metallic bearing plates which may be adhesively secured to other elements of the structure. The base member may have a lateral extent substantially greater than that of the rotatable portions to provide further tilt-free stability.
