and a movable element coupled to the pivot lever wherein a movement of the movable element parallel to the door leaf plane causes the pivot lever to execute a rotational movement for coupling of a car door including the door leaf with a shaft door and simultaneously change a spacing of the pivot lever from the door leaf plane by horizontal movement transverse to the door leaf plane. ### Claim 2 (depends on 1) The car door/shaft door coupling according to claim 1 wherein the car door/shaft door coupling has a first slide surface and a second slide surface which surfaces are inclined relative to the door leaf plane whereby movement of the movable element parallel to the door leaf plane by the first slide surface sliding on the second slide surface at the same time causes a rotational movement and an horizontal movement of the pivot lever. ### Claim 3 (depends on 2) The car door/shaft door coupling according to claim 2 wherein the first slide surface is formed complementary with the second slide surface. ### Claim 4 (depends on 2) The car door/shaft door coupling according to claim 2 wherein the support element has the first slide surface and the pivot lever has the second slide surface formed as threaded surfaces. ### Claim 5 (depends on 1) The car door/shaft door coupling according to claim 1 wherein an entrainer element is mounted on the pivot lever at an entrainer axis spaced from and parallel to the axis of rotation. ### Claim 6 (depends on 5) The car door/shaft door coupling according to claim 5 wherein the entrainer element is a first entrainer element and the pivot lever is a first pivot lever, a second entrainer element is positioned parallel to and spaced from the first entrainer element, wherein the second entrainer element is mounted on a second pivot lever at another entrainer axis spaced from and parallel to the axis of rotation. ### Claim 7 (depends on 6) The car door/shaft door coupling according to claim 6 wherein the first and second pivot levers are rotatably mounted on the support element. ### Claim 8 (depends on 1) The car door/shaft door coupling according to claim 1 wherein the movable element is coupled with the pivot lever at a bearing axis parallel to and spaced from the axis of rotation. ### Claim 9 (depends on 1) The car door/shaft door coupling according to claim 1 wherein the pivot lever is connected with the movable element by a bearing. ### Claim 10 (depends on 1) The car door/shaft door coupling according to claim 1 wherein the support element is one of integral to the door leaf and fastened to the door leaf. ### Claim 11 (depends on 1) The car door/shaft door coupling according to claim 1 including a guide device at which the support element is guided perpendicularly to the door leaf plane, the guide device being fastened to the door leaf. ### Claim 12 (depends on 11) The car door/shaft door coupling according to claim 11 wherein the pivot lever has a slot and the movable element has a pin, wherein the pin engages in the slot. ### Claim 13 (depends on 1) A door system of an elevator installation including the car door/shaft door coupling according to claim 1. ### Claim 14 (depends on 13) The door system according to claim 13 wherein the door leaf comprises: a pendulating guide mount with at least two damping elements and at least one pendulating guide limiter; and a floating block mounted in the pendulating guide mount and coupled with the support element, wherein the floating block is spring loaded against abutments in a horizontal direction parallel to the door leaf plane at both sides by a respective one of the damping elements and wherein the pendulating guide limiter prevents pendulating movement in directions not corresponding with the horizontal direction parallel to the door leaf plane. ### Claim 15 (depends on 13) The door system according to claim 13 including a secondary car door/shaft door coupling and an actuator, wherein the actuator executes an actuator movement causing the movement of the movable element of the car door/shaft door coupling and a secondary movement that is substantially equal to a movement of a secondary movable element of the secondary car door/shaft door coupling. ### Claim 16 (depends on 15) The door system according to claim 15 wherein the actuator is a drive motor.
