Elevator system with an installation bracket

An elevator system having an elevator shaft laterally bounded by a door-side shaft wall, the door-side shaft wall having a shaft door opening connecting the elevator shaft to an associated floor, the elevator system comprising:

• an installation bracket fixed at the shaft door opening of the door-side shaft wall;
• wherein the installation bracket is adapted to fix guide rails in the elevator shaft, the guide rails, when fixed in the elevator shaft, guiding an elevator car;
• the installation bracket including at least one floor fixing section adapted to fix the installation bracket to a horizontal surface of the associated floor;
• the installation bracket including a crossmember forming the at least one floor fixing section and two side members extending from and running at right angles to the crossmember, each of the side members adapted to fasten one of the guide rails, each of the side members being tapered with a wider end proximal to the crossmember;
• wherein a first of the side members is arranged at a first end of the crossmember and a second of the side members is arranged at a second end of the crossmember;
• wherein the crossmember is positioned on the associated floor outside of the elevator shaft and is closed by a vertical rib at the door-side shaft wall;
• a shaft door arranged at the shaft door opening outside a cross-sectional area of the elevator shaft, the shaft door having components arranged in vertical alignment at the associated floor;
• and
• wherein the shaft door components outside the cross-sectional area of the elevator shaft include at least one door leaf, and/or a door sill and/or at least one door leaf guide rail for guiding the at least one door leaf.
