Abstract
An expansible table includes a round tabletop formed of four equal sectors or quadrants for sliding movements on tracks between retracted and extended positions which permits the insertion of inserts or leaves to enlarge the size of the table. Guide pins downwardly extending from each sector are captured in associated spiral slots of a rotatably mounted platform or plate, so that rotation of the slotted plate facilitates simultaneous movement of all the sectors to the desired positions. Such expansion and contraction of the table can be accomplished by one individual in an effortless and a convenient manner.
