ABSTRACT:
A table includes a tabletop and a pair of opposing folding leg assemblies. Each folding leg assembly includes a base plate secured to the tabletop. A folding leg is pivotally connected to the base plate by a linkage arrangement that includes first links pivotally connecting the folding leg to the base to define first and second axes of rotation and a U-shaped second link pivotally connecting the folding leg to the base to define third and fourth axes of rotation. The second link further includes a transverse section, and a latch is secured to the base plate for releasably engaging the transverse section when the folding leg is in the extended position. The first, second, third, and fourth axes are spaced from each other and located so that the folding legs fold flat against the tabletop when in the folded position, but so that the axes do not move "on center" or "over center" and cause the legs to lock up when in the folded position.
