A folding table has a leg pivotally coupled to a bottom of a tabletop. A pair of links is pivotally coupled together and pivotally coupled in series between the tabletop and the leg. The pair of links, the tabletop and the leg form a four-bar, four-pivot linkage, including four 5 pivots and four bars defined between the pivots. The bars of the linkage are sized and the pivots of the linkage are located to resist movement of the linkage through an intermediate binding configuration between open and closed configurations. 26-- 18 -39 -34 Fig. 1a 14a 40 |
