A folding leg mechanism used with a folding leg assembly (106) supporting a platform (20) such as a table top. The leg mechanism includes spaced-apart platform engaging links (16); a platform engaging plate (18) pivotally connected the platform to one end (16a) of the platform engaging links; first and second spaced-apart, leg-engaging links (22) pivotably connecting the platform engagin links to the leg assembly. Each of the leg engaging links has a rod receiving slot (24) formed therein which includes a channel portion (24a), a ramp portion (24d) located proximate an end of the channel portion and a locking opening (24c) disposed proximate the ramp portion. A locking rod (26) extends between the platform engaging links with rod and portions (26b) being slidably received within the channel portion of the slot formed in the leg engaging links. When the rod end resides within the locking openings, the platform engaging links and the leg engaging lins are locked against relative pivotal movement. However, when the locking rod is lifted slightly, the rod ends move into the channel portion of the slot permitting free pivotal movement of the cooperating links.
