Abstract
A fastening system has two fastening elements for mounting a bracket of a rail system of an elevator installation. The fastening elements each have a clamping plate having a through-hole and a receiving sleeve receiving an anchor bolt. The receiving sleeves each have a through-opening for the anchor bolt and an angularly movable ball joint is formed between the clamping plate and the receiving sleeve.
Claims10
A fastening system for a bracket of a rail system of an elevator installation, the fastening system comprising:
- two fastening elements;
- an anchor bolt;
- at least two nuts;
- wherein each of the fastening elements has a clamping plate with a through-hole formed therein receiving the anchor bolt, a receiving sleeve with a through-opening formed therein receiving the anchor bolt, and an angularly movable ball joint formed between the clamping plate and the receiving sleeve, where each clamping plate has a flat clamping surface facing the bracket, and where the flat clamping surface of the clamping plate of at least one of the fastening elements has a diameter which is larger than a diameter of the ball joint formed between the clamping plate and the receiving sleeve;
- wherein the anchor bolt has an external thread, the nuts are screwed onto the external thread, and the fastening elements are arranged between the nuts on the anchor bolt;
- wherein the bracket has an opening with a diameter larger than a diameter of the anchor bolt;
- when the anchor bolt is anchored in a wall of the elevator installation and the bracket is positioned between the fastening elements with the anchor bolt extending through the opening, the bracket is aligned relative to the wall prior to locking the nuts on the anchor bolt to clamp the bracket between the fastening elements;
- wherein at least one of the fastening elements has a concave abutment of the ball joint formed in the clamping plate and a convex pressure piece of the ball joint formed on the receiving sleeve;
- and
- wherein the concave abutment is approximately hemispherical and the convex pressure piece is approximately hemispherical.
