Patent

CA 2009934

An elevator car having a clutch carried by a car door for engaging drive rollers of an adjacent hatch door via "open" and "close" vanes of the clutch. A door operator mounted on the car includes a door drive arm which is linked to the car door via a door crank arm. A door lock carried by the door clutch prevents normal operation of the door crank arm, unless the open vane of the door clutch contacts a hatch door drive roller. Thus, unless the car is in a floor landing zone, the car door cannot be opened by a passenger inside the car.
