ABSTRACT:
Elevator guide rails are mounted in an elevator shaft by pivoting into a cutout formed in one of a plurality of fastening plates located in the shaft and securing with a wedge inserted into the cutout. The guide rails are connected together by a rectangular cross section plug which fits into a cooperating rectangular cross section inner area of the guide rail. The plug is partially inserted into the upper end of each guide rail and the next upper guide rail is lowered onto the plug extending from the next lower guide rail. The butt joint between the guide rails does not interfere with the fastening plates since the plug connection is outside the mechanical fastening area. This means that the butt joints and the fastening positions can be at the same height in the elevator shaft without disturbing each other thereby permitting free choice in the placing of both the fastening points and the butt joints.
