ABSTRACT:
A folding leg mechanism for use in foldably interconnecting a foldable leg assembly with a support platform such as a table top. The mechanism includes platform engaging links; a platform engaging plate pivotally connected to the first and second links proximate the ends thereof; and first and second spaced-apart, leg-engaging links pivotally connected to the platform engaging links and to the leg assembly. Each of the leg engaging links has a rod receiving slot formed therein which includes a channel portion, a ramp portion located proximate one end of the channel portion and a locking opening disposed proximate the ramp portion. A locking rod extends between the platform engaging links with the end portion of the rod being slidably received within the channel portion of the slot formed in the leg engaging links. When the rod resides within the locking opening, the platform engaging links and the leg engaging links 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.
