Expandable table
An expanding table of the type in which a number of table top sections are caused to move outwardly and expand on rotation of the table top. The table top sections are coupled to a guide plate, which defines the positions between which the sections move. The guide plate is mounted for rotation and engages low friction rub blocks mounted along the inner perimeter of the outer edge of the table. The table top sections themselves are mounted on guides, which are at least partially received in the guide plate. Once the table top sections have been moved into the expanded configuration by rotation of the table top, table leaves are inserted in the spaces between adjacent table top sections to form a larger contiguous table surface.
