Abstract

A sliding guide shoe for an elevator includes a guide shoe housing and a two-part insert inserted into the guide shoe housing. The insert includes a damping element and a sliding element for guiding an elevator car or a counterweight.

First claim

The invention claimed is:

1. A sliding guide shoe for an elevator for transporting people or goods, the sliding guide shoe comprising:
a guide shoe housing;
a sliding element arranged in the guide shoe housing and having opposite ends, where the sliding element has two opposing side legs connected by a base leg each having a sliding surface arranged proximal an elevator guide rail;
wherein, when the sliding guide shoe is installed in the elevator, the side legs are oriented vertically and the opposite ends are oriented as an upper end and a lower end of the sliding element; and
wherein at least one of the upper end and the lower end extends in a non-horizontal course such that the sliding surfaces of the two opposing side legs have vertical extents which are asymmetrical across a vertical plane parallel to the sliding surfaces of the side legs.

2. The sliding guide shoe according to claim 1 wherein at least one of the upper end and the lower end of the sliding element has a sloping course.

3. The sliding guide shoe according to claim 2 wherein the sloping course, at least in parts, forms an angle of inclination relative to a horizontal direction.

4. The sliding guide shoe according to claim 3 wherein the angle of inclination is between 5° and 45°.

5. The sliding guide shoe according to claim 3 wherein the angle of inclination is between 10° and 30°.

6. The sliding guide shoe according to claim 3 wherein the angle of inclination is approximately 17°.

7. The sliding guide shoe according to claim 2 wherein the sliding element is formed as a U-shaped profile having the side legs running parallel and positioned opposite one another, the side legs and the base leg each having portions forming the upper end and the lower end of the sliding element, the portions forming at least one of the upper end and the lower end having a same slope.

8. The sliding guide shoe according to claim 7 wherein at least one of the upper end and lower end of the sliding element has rounded ramp surfaces at least in the portions of the side legs.

9. The sliding guide shoe according to claim 1 wherein the side legs each are connected to the base leg by a film hinge such that the side legs and the base leg are foldable relative to one another.

10. The sliding guide shoe according to claim 1 wherein the sliding element is shaped such that in an unfolded form the sliding element has a parallelogram-shaped outer contour without any right angles when the sliding element spread out or laid down on a plane.

11. The sliding guide shoe according to claim 1 wherein the sliding surface of the base leg has a round cross section.

12. The sliding guide shoe according to claim 1 wherein the guide shoe housing has a bore engaged by a pin, the sliding element has at least one retaining cam included in the pin engaging in the bore in the guide shoe housing, and the pin having a profiled outer contour of raised points.

13. The sliding guide shoe according to claim 1 wherein the sliding element is a component of a two-part insert, the insert having a damping element arranged between the sliding element and the guide shoe housing.

14. The sliding guide shoe according to claim 13 wherein the guide shoe housing has a bore engaged by a pin, the pin includes an annular buffer element formed in the damping element and a retaining cam included in the sliding element, the retaining cam being received in a hole in the annular buffer element, the annular buffer element having a profiled outer contour of raised points.

15. A sliding guide shoe for an elevator for transporting people or goods, the sliding guide shoe comprising:
a guide shoe housing;
an insert arranged in the guide shoe housing;
wherein the insert includes a sliding element having opposite ends and a damping element, where the sliding element has two opposing side legs connected by a base leg each having a sliding surface arranged proximal an elevator guide rail, and where the damping element is arranged between the sliding element and the guide shoe housing;
wherein, when the sliding guide shoe is installed in the elevator, the side legs are oriented vertically and the opposite ends are oriented as an upper end and a lower end of the sliding element; and
wherein at least one of the upper end and the lower end extends in a non-horizontal course such that the sliding surfaces of the two opposing side legs have vertical extents which are asymmetrical across a vertical plane parallel to the sliding surfaces of the side legs.

16. A sliding guide shoe for an elevator for transporting people or goods, the sliding guide shoe comprising:
a guide shoe housing;
a sliding element arranged in the guide shoe housing and having opposite ends connected to one another by longitudinal edges, the sliding element having two opposing side legs connected by a base leg each having a sliding surface arranged proximal an elevator guide rail;
wherein, when the sliding guide shoe is installed in the elevator, longitudinal edges are oriented vertically and the opposite ends are oriented as an upper end and a lower end of the sliding element; and
wherein at least one of the upper end and the lower end extends in a non-horizontal course such that a continuous edge of the sliding surface at the at least one end, along one of the side legs, the base leg and the opposing side leg, is not horizontal.
