Abstract: A surgical operating table has leg sections, which are displaceable about a vertical axis and a horizontal axis. Each leg section is locked in position by two gas struts, which lock respectively about the vertical and horizontal axes. Vent buttons on the gas struts are connected via push rods to opposite ends of a lateral beam. The lateral beam is engaged, close to the end coupled to the strut locking about the vertical axis, by a manual release handle beneath the foot end of the leg section. Lifting the handle displaces the one end of the beam initially and then the other end, so that the leg section is released for movement about the vertical axis before it is released for movement about the horizontal axis.
