Abstract

Abstract A convertible desk and conference table having a table-top surface supported by a pillar means. The table-top surface includes a central section and two wing sections disposed along and rearwardly of the central section to define an open area. A leaf conforming in shape to the open area is disposed on guides beneath the central section of the table-top surface. A pair of camming ramps are disposed adjacent the sides of the wing sections and operate to raise the leaf upward to the table-top surface. The convertible desk and conference table is changed from a desk configuration to a conference table configuration by pulling the leaf along the guides and up the camming ramps. The leaf is then joined with the central section of the table-top surface to complete the formation of the conference table.
