US 4,807,838 A · Table leg with wire raceway

Abstract

A hollow table leg assembly for supporting a tabletop having a vertical passage extending therethrough. The assembly includes a top plate which is fastened to the underside of the tabletop at the vertical passage. A downwardly-extending, circular protuberance is formed in the top plate and defines a recess beneath the vertical passage in the tabletop. A downwardly-facing annular lip is formed on the protuberance below the recess. A plurality of wire passages are formed in the protuberance around a central passage. Three downwardly-projecting ribs are formed on the underside of the top plate and extend radially inwardly of the annular lip. A base member having legs and a centrally located, vertically-extending passage with an upwardly-facing, annular recessed shoulder is formed around the passage. A tab extends across the shoulder. A cylindrical tube extends between the top plate and the base member. The top end of the tube and the bottom end of the tube is seated on the recessed shoulder of the base member. Notches are formed in the top and bottom ends of the tube to receive the ribs and the tab to lock the tube against rotation. A plug closes the central passage of the base member. The plug has a collar which engages the base member around its central passage and a hub portion which extends into the tube. Wire passages and a central passage extend axially through the plug. A threaded rod extends from the recess of the top plate, through the central passage thereof, through the tube and through the central passage of the plug. Nuts engage the ends of the threaded rod, the top plate and the plug to hold the assembly together.
