ABSTRACT:
A furniture leg is provided with means for compensating for uneven floor levels. Such means take the form of a rocker (17") protruding from a cavity in the lower end of the leg. Leaf springs (4") bias the rocker downwardly to a mid-position. Arched pistons (25") on the rocker (17") extend into arched chambers (22") in the leg which intercommunicate with one another through a throttle (23"). The axis of the arched pistons and chambers and closely fitting curved surfaces (5", 6") of the rocker and leg are all centered on the axis about which rocking occurs and which is provided by the engagement of the upper surface of the rocker with a ridge (19") on the socket roof.
