Claim:
Equipment on an elevator car for temporarily coupling a car door leaf with a shaft door leaf and for actuating a car door lock comprising: a pair of adjusting elements pivotably mounted at a car door leaf; first and second entraining runners connected with said adjusting elements wherein a mutual spacing of said entraining runners can be adjusted by pivoting said adjusting elements between an uncoupling setting and a coupling setting, said entraining runners in the coupling setting being adapted to co-operate with at least one coupling element which is mounted at the shaft door leaf and which exerts a contact force on one of said entraining runners; and a pair of articulation members each pivotably connected with one arm of an associated one of said adjusting elements and with said first entraining runner, whereby the contact force causes said first entraining runner to execute an additional movement which is securely and precisely guided by said articulation members and which causes unlocking of the car door lock.
