ABSTRACT:
An extendable table has a legged base defining a horizontal support surface extending in longitudinal and transverse directions and having a pair of outer transversely extending edges, a first table panel resting on the support surface and having a transversely extending inner edge intermediate and generally parallel to the outer edges, and a second table panel restable on the support surface, having a transversely extending inner edge buttable with the inner edge of the first panel, and formed with a pair of transversely open and longitudinally extending grooves. Respective rollers on the base underneath the second panel define a transversely extending first pivot axis, and extend transversely into guiding engagement with the grooves. Thus the second panel can slide longitudinally relative to the base on the rollers and can be pivoted on the rollers about the first pivot axis. A pair of parallel links each have one end pivoted about a second transverse axis on the base and generally parallel to the first transverse axis and another end pivoted on the second panel about another transverse axis. Thus the second panel can move with simultaneous pivoting about the first axis and sliding perpendicular thereto between an inner position with its inner edge butting the inner edge of the first panel and an outer position with its inner edge spaced from the inner edge of the first panel. A leaf is engageable in the outer position of the second panel between the inner edges.
