An adjustable-height article of furniture, such as a table, includes a generally horizontal top member, and a pair of transversely spaced, elongated leg members each having opposite ends. The top member includes transversely spaced longitudinal elements having longitudinally extending, elongated slots formed therein. One end of each leg member has a pin secured thereto which is slidably received in a respective slot, the other end being adapted to engage a supporting surface. A pair of transversely spaced, elongated support members is provided each having opposite ends, one end of each support member being pivotally connected to the top member at a point longitudinally spaced from the slots, and a point on each support member spaced from the one end being pivotally connected to a respective leg member intermediate its ends. Elongated flexible elements, such as lengths of rope, are provided each having one end secured to a respective leg member adjacent its one end, and a pair of wedge members are provided on the top member respectively spaced longitudinally from the slots in the direction of the support members which receive and adjustably clamp the flexible elements thereby to secure the one ends of the leg members at an infinite numbers of selected points along the slots. |
