Abstract

A fastening apparatus for fastening a drive of an elevator system, wherein the elevator system includes an installation structure for installing the drive, has a beam with two feet for fastening the beam to the installation structure. The fastening apparatus includes a drive bracket for receiving the drive, wherein the drive bracket is fastened to the beam, and a support leg that is fastened at one end to the drive bracket and additionally supports the drive bracket on the installation structure.

First claim

The invention claimed is:

1. A fastening apparatus for fastening a drive of an elevator system, wherein the elevator system includes an installation structure for installing the drive, the fastening apparatus comprising:
a beam having two feet adapted to fasten the beam to the installation structure;
a drive bracket adapted to receive the drive, wherein the drive bracket is fastened to the beam;
a support leg having one end fastened to the drive bracket and being adapted to support the drive bracket on the installation structure; and
wherein the support leg includes at least two elements that are displaceable relative to one another and that can be displaced telescopically into one another for selectively adjusting a length of the support leg, and wherein the at least two elements can be latched together to fix the selected length of the support leg.

2. The fastening apparatus according to claim 1 wherein the support leg has a support foot at another end and the support foot rests flat on the installation structure when the fastening apparatus is installed on the installation structure.

3. The fastening apparatus according to claim 1 wherein the beam has two parallel support plates connected to one another by at least one connecting plate, the feet are fastened to the at least one connecting plate, and the drive bracket is fastened to the support plates.

4. The fastening apparatus according to claim 3 wherein each of the feet is formed by a plate assembly made up of the at least one connecting plate and a fastening plate adapted to fasten the beam to the installation structure.

5. The fastening apparatus according to claim 4 wherein the fastening plate is wider than the at least one connecting plate and protrudes beyond the at least one connecting plate on opposite sides of the fastening plate.

6. The fastening apparatus according to claim 4 wherein the plate assembly includes at least one intermediate element, the at least one intermediate element being arranged between the fastening plate and the at least one connecting plate, and the at least one connecting plate rests on the at least one intermediate element.

7. The fastening apparatus according to claim 4 wherein the plate assembly includes a first intermediate element and a second intermediate element, the first intermediate element and the second intermediate element being arranged next to one another between the fastening plate and the at least one connecting plate and the at least one connecting plate rests on the first intermediate element and on the second intermediate element.

8. The fastening apparatus according to claim 4 wherein the support plates each have an axle receptacle formed therein, the axle receptacles adapted to receive an axle of a deflection roller.

9. The fastening apparatus to claim 4 wherein the support plates each have an installation portion at which a deflection roller bracket is fastened and suspended.

10. The fastening apparatus according to claim 1 wherein the feet are arranged at opposite ends of the beam.

11. The fastening apparatus according to claim 1 wherein the drive bracket includes a drive plate adapted to receive the drive and a tower supporting the drive plate, the drive plate being fastened to a first end of the tower and a second end of the tower being fastened to the beam.

12. An elevator system comprising:
a drive;
an installation structure for installing the drive in the elevator system; and
the fastening apparatus according to claim 1 wherein the drive is fastened to the installation structure by the fastening apparatus.

13. The elevator system according to claim 12 wherein the installation structure includes a base plate and at least one installation support, the beam of the fastening apparatus is fastened to the at least one installation support by at least one of the feet of the fastening apparatus and the support leg supports the drive bracket on the base plate.
