Abstract
An elevator shaft door frame incorporates a control arrangement for an elevator installation including a control unit. The control unit is fixed in a chamber of a frame element of the door frame. The chamber communicates with an outside opening in the door frame, which opens at a floor, and is closed with a cover. The cover can be moved from the closed position by demounting to a service position in which access to the chamber is free. In addition, the door frame has an inside opening to the chamber which is accessible from the elevator shaft.
