ABSTRACT:
A table (20) comprises a pair of side leaves (22,23) movable with respect to each other to abut each other for forming a small tabletop (27), a center leaf (24) selectively interposable between the pair of side leaves (22,23) for forming a large tabletop (37), and a moving mechanism (25) for selectively automatically configuring the leaves (22,23,24) into a small or a large tabletop (27,37). The moving mechanism (25) includes an apparatus (40) for sliding the side leaves (22,23) toward and away from each other, a cam apparatus (41) for raising and lowering the center leaf (24) and for storing the center leaf (24) below the side leaves (22,23) and for retrieving the center leaf (24) from storage, and a driving apparatus (88) for moving the slide apparatus (40) and the cam apparatus (41).
