Abstract

An adjustable roller-guide shoe for guiding an elevator car or a counterweight of an elevator installation contains a roller carrier, which can be fastened on the car or the counterweight, a guide roller and a roller spindle, which is arranged in the roller carrier and accommodates the guide roller. The roller spindle is positioned in the roller carrier by an adapter having an installation contour which matches a corresponding accommodating contour of the roller carrier. The adapter is configured to be fixed in different installation positions in relation to the roller carrier, and thus the roller spindle can be placed in different positions in the roller carrier, depending on the installation position of the adapter. It is thus possible for the roller-guide shoe to be operated with different roller diameters or to be adapted to different rail-web dimensions.

First claim

The invention claimed is:

1. A roller-guide shoe for guiding an elevator car or a counterweight in an elevator facility, comprising:
a roller bearing adapted to be attached to the car or the counterweight;
at least one guide roller;
at least one roller axle disposed in the roller bearing and receiving the guide roller;
at least one adapter installed in the roller bearing for positioning the roller axle in the roller bearing, wherein the adapter has an installation contour, which fits to a corresponding receiving contour in the roller bearing, the adapter having a through hole receiving the roller axle, the hole having a center axis, the installation contour being symmetrical at least with respect to a first plane of symmetry for the adapter, wherein the first plane of symmetry extends parallel to the center axis, and the center axis of the hole being disposed at a spacing from the first plane of symmetry such that the adapter can be secured in at least two different installation positions in the roller bearing, and the roller axle is placed in different positions in the roller bearing depending on the installation position of the adapter.

2. The roller-guide shoe according to claim 1 wherein the installation contour of the adapter is furthermore symmetrical with respect to a second plane of symmetry for the adapter, and a line of intersection for the two planes of symmetry defines a central axis for the adapter, which central axis is disposed parallel to and at a spacing from the center axis, and wherein the receiving contour of the roller bearing, cooperating with the installation contour, prevents a turning of the adapter in the roller bearing.

3. The roller-guide shoe according to claim 2 wherein the installation contour of the adapter, as well as the receiving contour of the roller bearing, are in a shape of a substantially equilateral polygon, such that the adapter can be secured in at least two different rotational positions in the roller bearing about the central axis of the adapter, and the center axis of the hole receiving the roller axle is disposed parallel to and offset from the central axis, wherein corners of the polygon are rounded.

4. The roller-guide shoe according to claim 2 wherein the installation contour of the adapter, as well as the receiving contour of the roller bearing, are in a shape of a rhombus, such that the adapter can be secured in at least two different rotational positions in the roller bearing about the central axis of the adapter, and the center axis of the hole for receiving the roller axle is disposed parallel to and offset from the central axis, wherein corners of the rhombus are rounded.

5. The roller-guide shoe according to claim 4 wherein roundings of opposing ones of the corners of the rhombus are formed with a same radii, and roundings of adjacent ones of the corners of the rhombus are formed with different radii.

6. The roller-guide shoe according to claim 1 wherein the adapter is formed of an oscillation damping material to support the roller axle in the roller bearing to be cushioned against vibrations.

7. The roller-guide shoe according to claim 6 including at least one air pocket or air hole formed in the adapter to affect an elasticity of the adapter.

8. The roller-guide shoe according to claim 1 wherein the adapter is formed of a polyurethane material to support the roller axle in the roller bearing to be cushioned against vibrations.

9. The roller-guide shoe according to claim 1 wherein the hole receiving the roller axle is a circular hole, and the roller axle has a first, round axle region, configured to be positioned in the circular hole in the adapter, and the roller axle has a bearing region for receiving the guide roller, wherein the bearing region is offset eccentrically relative to the first axle region.

10. The roller-guide shoe according to claim 1 wherein the roller bearing is substantially symmetrical and receives two of the roller axle each with one of the guide roller received thereon, the guide rollers being disposed on opposite sides of a guide beam, wherein the two roller axles and the two guide rollers are each attached to the roller bearing with two of the adapter spaced apart from one another, wherein guide forces are introduced into the roller bearing by a pair of forces generated by the spaced apart adapters.

11. The roller-guide shoe according to claim 10 wherein the two roller axles are connected by a connecting bracket, and are secured against turning, wherein the connecting bracket has different hole positions corresponding to the different positions for the roller axles in the roller bearing.

12. The roller-guide shoe according to claim 10 wherein the roller bearing accommodates a further guide roller, which is disposed at a right angle to the two guide rollers disposed on the two roller axles, and which is supported by at least one of a spring-loaded lever and a limit stop damper with respect to the roller bearing, wherein the further guide roller is pressed against a central guide surface on the guide beam.

13. An elevator facility having a plurality of the roller-guide shoe according to claim 1 attached to at least one of the elevator car and the counterweight.
