Rotatable table

Abstract

A table includes a base and a table top for positioning on the base. The table top includes a unitary construction and a substantially flat, uninterrupted upper surface and a bottom surface. A plurality of rollers are rotatably secured to the base and rotatably engage the bottom surface of the table top such that the table top rotates in a horizontal plane about a rotational axis. A mechanism on the base engages the table top and prevents the table top from moving laterally in the horizontal plane with respect to the base.

1 . A table comprising: 
 a base;    a table top having a rotational axis and a unitary construction with a substantially uninterrupted upper surface and a bottom surface and wherein the table top positions on the base;    a first plurality of rollers rotatably secured to the base and rotating in a vertical plane for rotatably engaging the bottom surface of the table top such that the table top rotates about the rotational axis; and    a mechanism positioned on the base and below the bottom surface of the table top engaging the table top for preventing the table top from moving laterally in a horizontal plane with respect to the base.    
   
   
       2 . The table of  claim 1  and further comprising a ring attached to a bottom surface of the table top and wherein the first plurality of rollers engage the ring such that the table top rotates about the rotational axis.  
   
   
       3 . The table of  claim 2  and wherein the ring is moveably attached to the table top such that a center point of the ring substantially aligns with the axis of rotation of the table top.  
   
   
       4 . The table of  claim 1  and further comprising an extension extending downwardly from the table top when the extension is substantially located on the rotational axis.  
   
   
       5 . The table of  claim 4  and wherein the mechanism comprises a plate substantially centrally located on the base having an aperture for accepting the extension wherein the cooperation of the extension within the aperture prevents lateral movement of the table top relative to the base.  
   
   
       6 . The table of  claim 1 , wherein the base comprises: 
 a loop; and    a plurality of legs attached to the loop.    
   
   
       7 . The table of  claim 6  and wherein the base further comprises a plurality of brackets attached to the loop wherein the first plurality of rollers rotatably attach to the plurality or brackets.  
   
   
       8 . The table of  claim 3  and further comprising a cylindrical ring attached to a bottom surface of the table top and wherein the cylindrical ring further comprises a substantially vertical interior side wall.  
   
   
       9 . The table of  claim 8  and wherein the mechanism comprises a second plurality of rollers rotatably secured to the base wherein the second plurality of rollers rotate in a substantially horizontal plane of rotation wherein the second set of rollers engage the substantially vertical interior side wall.  
   
   
       10 . A table having a rotating table top, the table comprising: 
 a base;    a first plurality of rollers attached to the base and positioned to rotate in a vertical plane;    a table top having a substantially uninterrupted upper surface and having an axis of rotation and comprising a substantially circular rail attached thereto for engaging the first plurality of rollers and having an axis of rotation; and    wherein the table top is rotatable  360  degrees in a substantially horizontal plane by engaging the plurality of rollers.    
   
   
       11 . The table of  claim 10  and wherein the substantially circular rail adjustably positions on the table top such that a center point of the substantially circular rail substantially aligns with the axis of rotation.  
   
   
       12 . The table of  claim 10  and wherein the rail comprises a substantially flat surface for engaging the plurality of rollers.  
   
   
       13 . The table of  claim 10  and further comprising a mechanism attached to the base and engaging the table top for preventing lateral movement of the table top.  
   
   
       14 . The table of  claim 10  and wherein the rail comprises an interior substantially interior vertical side wall.  
   
   
       15 . The table of  claim 14  and further comprising a second plurality of rollers attached to the base that rotate in a horizontal plane and wherein the second plurality of rollers engage the interior substantial vertical side wall to prevent the table top from laterally moving.  
   
   
       16 . The table of  claim 10  and further comprising an extension extending downwardly from the table top wherein the extension is substantially located on the rotational axis of the table top.  
   
   
       17 . The table of  claim 16  and wherein the base comprises a plate having an aperture for accepting the extension wherein the cooperation of the extension within the aperture prevents lateral movement of the table top relative to the base.  
   
   
       18 . A rotatable table comprising: 
 a table top of a unitary construction and having a substantially uninterrupted upper surface and having a rotational axis;    a base for supporting the table top;    a rail attached to a bottom surface of the table top;    a first plurality of rollers rotatably connected to the base and rotatably in a vertical plane for engaging the rail to rotate the top about the rotational axis; and    a second plurality of rollers rotatably attached to the base for rotatable in a horizontal plane and engaging the rail for restraining lateral movement of the table top during rotation.    
   
   
       19 . The table of  claim 18  and wherein the rail comprises a substantially vertical side wall for engaging the plurality of horizontally rotatable rollers.  
   
   
       20 . The table of  claim 19  wherein the rail comprises an inwardly extending lip attached to a bottom edge of the vertical wall and wherein the lip engages a bottom point of the first plurality of rollers to retain the table top to the base.
