Abstract

An interlock for center opening elevator hoistway doors, in which one door is powered and the other door is operated by a cable from the powered door, has an interlock switch operated by the powered door to prevent the elevator car from leaving the landing before the hoistway doors are closed. When the idle door is open, a tab connected to a spring loaded pivoted lever swings into a position underlying the interlock to prevent the interlock hook from dropping into position to close the interlock switch. When the idle door closes, a cam mounted on the idle door engages a cam follower on the lever and rotates the lever tab clear of the interlock hook, simultaneously swinging a latch connected to the lever into a catch mounted on the cam so that the idle door is securely locked in closed position once the interlock hook drops into position to lock the powered door.
