ABSTRACT:
A table with extendable legs includes a table top and a plurality of legs extending vertically downward from the table top. Each leg is variably juxtaposed with an extension member along a tapered tongue and groove interface. Each leg and extension member pair is bound together by a yoke. Each yoke has a pivotal cam lever which is rotatable with over center action between a locked position and an unlocked position, so that a pin-to-hole engagement is established between the leg and extension member by urging the lever from its unlocked position to its locked position.
