  • Patent number: 5887531
    Abstract: A collapsible table includes a tabletop having a center leaf, intermediate first and second end leaves. First and second pairs of support arms and support legs are pivotally mounted about an axle depending from the center leaf. The arms and legs of each pair are pivotal about the axle in opposed directions between a first collapsed position and a second functional position. The support arms at the second position position the leaves attached thereto in a coplanar relationship with the center leaf. At their functional position the support legs provide underlying support to the center leaf. Slots in the arms and legs engage a key depending from the center leaf so as to maintain the arms and legs at their functional positions. A spring bias on the axle further urges the slots against the key with the weight of the center leaf urging the key into the slots. Upon lifting the center leaf the keys disengage the slots which allows the arms and legs to pivot to their collapsed positions.
