US Patent 7220185 Height-adjustable game table

A game table is disclosed having a support structure including leg assemblies at either end supporting the table. The support structure includes release/lock mechanisms and counterbalancing elements causing an upward force against said tabletop to substantially offset the weight of said tabletop.

The release/lock mechanisms are disposed proximate to the players normal positions to allow the players to alter the height of the tabletop without leaving their playing positions.
