Abstract
A door panel position control mechanism for a multiple panel horizontal sliding door assembly of a freight elevator landing. The mechanism comprises a multiple node scissors linkage that is configured to be easily installed and initially adjusted and which has its parts symmetrically balanced about a vertical plane such that excessive eccentric loading on the components is reduced and a long service life is obtained with reduced wear and a reduced need for periodic adjustment.
