Abstract

A diverting pulley adapter is provided for converting an existing pulley, the adapter enabling a maintenance of an existing running path for diverting a suspension, like an elevator-rope or an elevator-belt, the adapter having a base with at least one fixing component for anchoring the adapter, at which base a set of pulleys is provided. The adapter includes a first deflection pulley being mounted rotatable on its rotation axis, and at least a further second deflection pulley being mounted rotatable on its rotation axis, wherein the rotation axes of the pulleys are interspaced, respectively. The positions of those pulleys forming the set of pulleys are adjustable in view of their fixation, respectively, and symmetrically in relation to the fixing component.

First claim

The invention claimed is:

1. A diverting pulley adapter for converting an existing pulley, the adapter enabling a maintenance of an existing running path for diverting a suspension, the diverting pulley adapter comprising:
a base with a fixing component for anchoring the diverting pulley adapter;
a set of pulleys provided at the base, the set of pulleys comprising:
a first deflection pulley mounted rotatable on a rotation axis thereof; and
at least a further second deflection pulley mounted rotatable on a rotation axis thereof,

wherein the rotation axes of the first pulley and the at least a further second pulley are spaced from one another,
wherein the positions of the pulleys forming the set of pulleys are adjustable in view of their fixation, respectively, and symmetrically in relation to the fixing component, and
wherein each pulley of the set of pulleys is held in a respective longhole, which longholes are all arranged in the base and symmetrically with respect to the fixing component.

2. The diverting pulley adapter according to claim 1 , wherein the longhole/longholes is/are curved.

3. The diverting pulley adapter according to claim 1 , wherein the position of the pulleys are implemented such that its mounting position is continuously adjustable.

4. The diverting pulley adapter according to claim 1 , wherein the suspension is one of an elevator-rope and an elevator-belt.

5. The diverting pulley adapter according to claim 3 , wherein the longhole/longholes is/are curved.
