Abstract
An operating table has two leg sections each of which has a rotatable shaft extending along its length. Each shaft carries a gear that engages another gear fixed with the table such that raising or lowering the leg section causes the shaft to rotate. A helical spring extends helically around each shaft and is arranged to coil up when the leg section is lowered, so that the weight of the section is counterbalanced.
