  • Sealing device with magnetically movable door seal for a closable door leaf of an elevator installation
    Patent number: 7445089
    Abstract: An elevator installation has a sealing element that is movable by an electromagnetic actuator from a first position to a second position. The sealing element includes a seal carrier that is movably arranged at a door leaf of a door of the elevator installation. An electromagnetic actuator is fastened in the region of the door and upon actuation acts on the seal carrier to move it from the first position to the second position. An electrical circuit triggers the actuation before the door leaf executes an opening movement.
