ABSTRACT:
A folding table includes a tabletop and a number of legs operable between a folded and an extended position. A folding table leg apparatus associated with each of the legs comprises a top plate mounted to the tabletop, the top plate having a pair of side flanges. Each of the side flanges has a height greater than the effective diameter of one leg. The flanges and the top plate define an envelope within which the leg is contained in its folded position and the folding apparatus itself is fully contained within the envelope when the leg is in its folded position. The folding table leg apparatus includes a pair of brace links straddling the leg, each of the pair of brake links being pivotably mounted at a first end to the top plate and pivotably connected at a second end to diametrically opposite portions of the leg, such that the brace links provide support for the leg in its extended position. A pair of swivel brackets straddling the leg are pivotably mounted at a first end to the side flanges and are pivotably connected at a second end to diametrically opposite portions of the leg adjacent the top of the leg, by way of a first pivot rod extending through the leg. A support surface is associated with the top plate for vertically supporting the first pivot rod when the leg is in its extended position. The folding table leg apparatus also includes a pair of independent lever arms straddling the leg and pivotably mounted to the top plate for releasably engaging and urging the first pivot rod into the support surface when the leg is in its extended position.
