  • Patent number: 6250014
    Abstract: The present invention is a compact door coordinator which includes a relatively narrow housing having mounted therein and extending therefrom a lead control lever and a longer trailing control lever. Both control levers are spring biased to extend from the housing when the doors are open. A relatively simple linkage extends from the lead control lever to the trailing control lever for retaining the ladder in its extended position until the lead door contacts the lead control lever. At that point, the lead control lever is pushed into the housing and rotated against the force of a torsion spring, causing the linkage to move and thereby rotating a cam which then releases the trailing control lever allowing the trailing door to push the trailing control lever into the housing to complete the closing process.
