ABSTRACT:
A direction indicating device (4) for elevators is built into the door frame (3) near a floor door (1). The device (4) consists essentially of a retaining element (9), an up-direction arrow (10) and a down-direction arrow (11). In order to make the indicating device direction arrows (10, 11) visible from possibly all positions or viewing angles of the passengers on the floor, the device (4) is arranged on the door frame (3) three dimensionally with the direction arrows (10, 11) mounted on the front wall (14) as well as on the side wall (15) of the door frame (3). For further improvement of the visibility, another indicating device (4) can be arranged in a similar manner on the other side of the door frame (3). With the arrangement of this indicating device (4) on both sides of the floor door (1), a practically total visibility of the direction arrows (10, 11), through almost 180 degrees in the hallway, is assured.
