Abstract

Disclosed is a table leg system including a leg, an anchor pivotally supporting the leg, and a locking sleeve slidingly engaged with the leg. The locking sleeve is at least partially encircled by at least a single ridge. An embodiment of the table leg system includes a leg, an anchor pivotally supporting the leg, and a locking sleeve slidingly engaged with the leg. The locking sleeve is at least partially encircled by a single groove. Another embodiment of the table leg system includes a table engagement anchor, a locking cylinder integrally extending from a planar surface of the table engagement anchor, and a leg extending from the table locking cylinder. The leg is repositionable between an extended position and a folded position. Yet additional embodiments of the table leg system include a table leg, an anchor plate comprised of a planar surface, and a neck extending perpendicularly from the planar surface of said anchor plate. The neck includes a recess, and at least one retaining projection extending into the recess integrally configured in a surface of the neck. Yet a further table leg system includes an anchor plate having a planar surface, a neck that extends perpendicularly from the planar surface of the anchor plate; a plurality of outwardly protruding reinforcing ribs around an intersection of the neck with the planar surface of the anchor plate.

Claims

1. A table leg system comprising:

a leg;

an anchor pivotally supporting said leg;

a locking sleeve slidingly engaged with said leg; and
