Inset turntable for articles of furniture

Abstract

A turntable assembly to be inset in an aperture in the surface of an article of furniture. It includes a circular ring fitted in the recess and held there by a peripheral lip that rests on a peripheral band on the surface. Bearings carried by the ring face inwardly rotatable to support a plate-like turntable inside the ring.

1 . An inset turntable for the top surface of the top of an article of furniture, said top surface having a circular aperture therein having a central axis normal to said top surface, extending below said top surface, contiguously bounded by a flat peripheral band, and having an axially extending concentric circular wall beneath said band, said inset turntable comprising: 
 a circular ring having a central axis, an axially extending cylindrical wall having an upper and a lower edge, and a peripheral lip extending around said upper edge, projecting laterally therefrom with a planar ring-shaped lower face proportioned and arranged to make surface to surface contact with said band on said top surface, the outer surface of said wall depending into said circular wall of said aperture;    a plurality of bearings mounted to said cylindrical wall of said ring, extending inwardly therefrom; and a circular turntable plate rotatably placed in said ring resting on said bearings, thereby adapted to rotate around said central axis.    
   
   
       2 . An inset turntable according to  claim 1  in which said bearings are roller bearings with axes of rotation normal to the central axis.  
   
   
       3 . An inset turntable according to  claim 1  in which said lip forms a continuous structure around said upper edge of said cylindrical wall.  
   
   
       4 . An inset turntable according to  claim 1  in which said bearings are disposed below said upper edge of said ring by a distance substantially equal to the thickness of the turntable plate.  
   
   
       5 . An inset turntable according to  claim 4  in which said turntable plate has a surface made of the same material as the top surface of the article of furniture.  
   
   
       6 . An inset turntable according to  claim 5  in which said band is recessed into said top surface of the article by a distance about equal to the axial thickness of the lip.  
   
   
       7 . A combination according to  claim 4  in which said turntable plate is made of glass.
