Claim:
Door coupler in connection with the car door of an elevator, said door coupler comprising coupling elements movable via a linkage and designed to engage at least one counter element provided on a landing door, said door coupler being associated with a locking hook that has a closed position for preventing movement of the car door and a released position for permitting movement of the car door, wherein the movement of the locking hook from the closed position to the released position being permitted when a coupling element is in contact with a counter element, and wherein an actuating power causing the coupling elements to engage the counter element is obtained from an operating means actuating the doors, characterized in that the door coupler comprises a first part having a plurality of elements forming a unit mounted on a car door, which comprises at least the coupling elements and at least one spring, and a second part having a plurality of elements forming a unit on a base plate mounted vertically above said first part, which comprises at least the locking hook, locking lever, operating lever and the transmission of actuating power from the operating means actuating the doors, and that the first part and the second part are mounted in separation from each other on the car door or at least so as to be movable together with it, and that the door coupler comprises a power transmission element between the first part and the second part, by means of which element a linkage movement occurring in the second part produces a linkage movement in first part, and a second power transmission element, by means of which the linkage movement occurring in the first part produces a movement of the locking hook.
