Abstract

The present invention relates to a coupling gear device for entraining a shaft door by means of an elevator car door that can be actuated by a door drive for elevator devices, comprising entrainment means (110) provided on the side of the elevator car door and counter entrainment means (210) arranged on the side of the shaft door. The counter entrainment means can be acted on by the entrainment means (110) for entraining the shaft door, wherein the entrainment means (110) and/or the counter entrainment means (210) can be lowered at least partially in the elevator car door or the shaft door.
