Abstract

A servicing device for a belt of an elevator system is provided including a housing and a guide member coupled to the housing. The guide member and the housing are disposed on opposite sides of the belt. At least one reservoir is disposed within the housing. The at least one reservoir contains one or more restoring materials. An applicator is configured to apply the one or more restoring materials to an adjacent surface of the belt. Application of the one or more restoring materials is configured to modify the geometry of the belt such that the modified geometry is substantially identical to the original geometry of the belt.

First claim

What is claimed is:

1. A servicing device configured for use with a belt of an elevator system having an original geometry, the servicing device comprising:
a housing;
a guide member coupled to the housing such that the guide member and the housing are disposed adjacent opposing surfaces of the belt;
at least one reservoir disposed within the housing, the at least one reservoir containing one or more restoring materials;
an applicator configured to apply the one or more restoring materials to an adjacent surface of the belt, wherein application of the one or more restoring materials is configured to modify a geometry of the belt such that the modified geometry is substantially identical to an original geometry of the belt; and
a curing attachment arranged downstream from the applicator with respect to a path of relative motion between the at least one belt and the servicing device.

2. The servicing device of claim 1 , wherein the servicing device is fixed at a hoistway of the elevator system and the belt is configured to move relative to the servicing device.

3. The servicing device of claim 1 , wherein the servicing device is connected to the belt and is configured to move relative to the belt.

4. The servicing device of claim 1 , further comprising a mechanism for measuring a thickness of the belt.

5. The servicing device of claim 1 , wherein the restoring material is a surface treatment configured to alter at least one of friction, noise, and traction of the belt.

6. The servicing device of claim 1 , wherein the one or more restoring materials is applied by printing or fused deposition.

7. An elevator system comprising:
an elevator car;
a motor;
a traction sheave operably connected to the motor drive rotation of the traction sheave;
at least one belt operably connected to the elevator car, the at least one belt having an original geometry and being arranged in frictional contact with the traction sheave such that rotation of the traction sheave urges movement of the elevator car; and
a servicing device for the at least one belt including:
a housing;
a guide member coupled to the housing;
at least one reservoir disposed within the housing, the at least one reservoir containing one or more restoring materials;
an applicator configured to apply the one or more restoring materials to an adjacent surface of the at least one belt, wherein application of the one or more restoring material modifies a geometry of the at least one belt such that the modified geometry is substantially identical to the original geometry of the at least one belt; and
a curing attachment arranged downstream from the applicator with respect to a path of relative motion between the at least one belt and the servicing device.

8. The elevator system of claim 7 , wherein the servicing device is fixed at a hoistway of the elevator system and the at least one belt is configured to move relative to the servicing device.

9. The elevator system of claim 7 , wherein the servicing device is configured to move relative to the at least one belt.
