Abstract

A safety gear alignment system for an elevator system includes an elevator shaft and an elevator car having an interior region and disposed in and moveable within the elevator shaft. Also included is an upright structure operatively coupled to the elevator car, the upright structure defining at least one aperture. Further included is a safety gear member having a brake and a frame, the frame operatively coupled to the upright structure. Yet further included is at least one access region defined by the frame of the safety gear member, the access region accessible from the interior region of the elevator car and wherein measurement between the frame and a guide rail of the elevator shaft is made for alignment of the safety gear member relative to the guide rail.

First claim

What is claimed is:

1. A safety gear alignment system for an elevator system comprising:
an elevator shaft;
an elevator car having an interior region and disposed in and moveable within the elevator shaft;
an upright structure operatively coupled to the elevator car and located along an exterior surface of one of the plurality of side walls, the upright structure extending in a longitudinal direction from the car floor to the car roof, the upright structure defining at least one aperture;
a safety gear member having a brake and a frame, the frame operatively coupled to the upright structure; and
at least one access region defined by the frame of the safety gear member, the access region accessible from the interior region of the elevator car and wherein measurement between the frame and a guide rail of the elevator shaft is made for alignment of the safety gear member relative to the guide rail.

2. The safety gear alignment system of claim 1 , wherein the access region comprises a notch.

3. The safety gear alignment system of claim 1 , wherein the access region comprises a pair of slots.

4. The safety gear alignment system of claim 1 , wherein the at least one access region comprises a first shim receiving region and a second shim receiving region each defined by the frame, the safety gear alignment system further comprising:
a first pair of shims extendable from the interior region of the elevator car through the at least one aperture of the upright structure and into the first shim receiving region of the safety gear member, the first pair of shims aligning the safety gear member relative to the guide rail of the elevator shaft; and
a second pair of shims extendable from the interior region of the elevator car through the at least one aperture of the upright structure and into the second shim receiving region.

5. The safety gear alignment system of claim 4 , wherein the first shim receiving region comprises a first notch and the second shim region comprises a second notch.

6. The safety gear alignment system of claim 5 , wherein the first notch is located at a top end of the frame of the safety gear member and the second notch is located at a bottom end of the frame.

7. The safety gear alignment system of claim 4 , wherein the first shim receiving region comprises a first pair of slots and the second shim receiving region comprises a second pair of slots.

8. The safety gear alignment system of claim 7 , wherein the first pair of slots is disposed proximate a top end of the frame of the safety gear member and the second pair of slots is disposed proximate a central region of the frame.
