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.

A door frame with a control arrangement for an elevator installation with an elevator shaft, comprising:
- a door frame element having an internal chamber and an outside opening in a first wall of said door frame element communicating with said chamber, said first wall being exposed at a floor when said door frame element is installed in a shaft door opening of the elevator shaft;
- a control unit fixedly mounted in said chamber;
- a cover attached to said door frame element in an operating position closing said opening and being movable to a service position permitting access to said control unit in said chamber from the floor for carrying out service operations at said control unit;
- and
- said door frame element having a second wall with an inside opening formed therein communicating with said chamber, said second wall facing an interior of the elevator shaft when said door frame element is installed in the shaft door opening of the elevator shaft, said inside opening providing access to said control unit in said chamber from the elevator shaft for carrying out maintenance operations at said control unit.
A method for accessing a control unit of an elevator installation wherein the control unit is mounted within a chamber inside a door frame element of a door frame installed in a shaft door opening of an elevator shaft, comprising the steps of:
- a) providing an outside opening in a first wall of the door frame element communicating with the chamber, the outside opening being exposed at a floor associated with the shaft door opening;
- b) closing the outside opening with a cover movable to a service position providing access to the control unit through the outside opening for carrying out service operations at the control unit;
- and
- c) providing an inside opening in a second wall of the door frame element communicating with the chamber and facing an interior of the elevator shaft for carrying out maintenance operations at the control unit.
