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.
Claims18
An expansible table comprising a base;
- a tabletop consisting of a plurality of separable sectors generally arranged about a central point and forming a first tabletop surface when said sectors are each in a retracted first position close to said central point, and at least adjacent ones of said sectors abut against each other;
- supporting means for movably supporting said sectors for movement within a plane defined by said tabletop between said retracted first position and an extended second position more remote from said central point to create spaces between at least adjoining sectors;
- inserts received within said spaces to provide a second tabletop surface defining an area greater than the area of said first tabletop surface;
- and actuating means for simultaneously moving all said sectors between said retracted first and extended second positions, whereby movement of said actuation means facilitates insertion and removal of said inserts and conversion of said tabletop between said first and second tabletop surfaces, said actuating means comprising a platform mounted for rotation about said central point, a first guide means on each of said sectors and a second guide means which cooperates with each of said first guide means said second guide means comprising at least one arcuate slot in said platform for each said sector which extends between said first and second positions, and said first guide means comprises a guide pin on each of said sectors slidably received within an associated at least one arcuate slot, whereby rotary movement of said platform causes all said guide pins to simultaneously move within said arcuate slots thereby causing all said sectors to move on said support means in a direction determined by the direction of rotation of said platform relative to said support means on which said sectors are slidably mounted.
