Adjustable height rotatable work table

Abstract

A worktable consists of a pedestal having an upwardly extending tubular member and a cylindrical member telescopically slideable therein. Thumbscrews along the length of the tubular member are tightenable against the surface of the tubular member to lock the upper end thereof is at the desired elevation. A tabletop having a downwardly extending tubular collar is rotatably fitted around the upper end of the cylindrical member. A flexible sleeve fitted between the inner surface of the collar and the outer surface of the tubular member creates resistance to rotation of the tabletop with respect to the pedestal. Finally, an adjustable thumbscrew extending through the collar and against the outer wall of the flexible sleeve enables an operator to vary the resistance to rotation of the top with respect to the pedestal.

What is claimed:  
     
         1 . A table comprising 
 a pedestal,    said pedestal having an upper end,    said upper end vertically moveable between a minimum elevation and a maximum elevation,    means for locking said upper end in a selected elevation between said minimum elevation and said maximum elevation,    a transverse top,    means for rotatably retaining said transverse top to said upper end, and    means between said upper end and said top for adjustably varying resistance to rotation of said top with respect to said upper end.    
     
     
         2 . The table in accordance with  claim 1  and further comprising a vertically extending tubular member on said pedestal and a cylindrical member telescopically slideable within said tubular member.  
     
     
         3 . The table in accordance with  claim 2  and further comprising a thumbscrew threaded into a hole through the wall of said tubular member for vertically locking said cylindrical member with respect to said tubular member.  
     
     
         4 . A table in accordance with  claim 3  wherein said top has a downwardly extending cylindrical collar having a cylindrical inner opening fitted around an upper end of said tubular member.  
     
     
         5 . The table in accordance with  claim 4  and further comprising levelers on a lower surface of said pedestal for positioning said pedestal on the surface of an underlying floor.  
     
     
         6 . The table in accordance with  claim 5  and further comprising a flexible sleeve within said collar for creating resistance to rotation of said table top with respect to said upper end of said tubular member.  
     
     
         7 . A table in accordance with  claim 1  and further comprising a collar extending downwardly from a lower surface of said table top and a flexible sleeve fitted in an inner surface of said collar for creating resistance to rotation between said top and said upper end of said pedestal.  
     
     
         8 . The table in accordance with  claim 7  and further comprising a threaded hole in said collar and a screw threaded in said hole for adjustably increasing or decreasing resistance to rotation of said top relative to said pedestal.
