Abstract
An adjustable height platform comprising a bottom platform, a top platform and a scissors linkage secured between the top and the bottom platforms. The scissors: linkage includes scissors legs which pivot about a pivot axis. A drive system provides a horizontal force to the scissors linkage. An unlocking mechanism lifts the pivot axis in response to the horizontal force and unlocks the scissors legs from a collapsed, retracted, and aligned position. After unlocking the legs, the horizontal force continues to raise the top platform with respect to the bottom platform.
