Abstract

A door coupling assembly for an elevator system. The coupling assembly includes a first vane, including a first surface extending longitudinally vertically to the elevator car door and a second vane, including a second surface and a third surface extending longitudinally vertically in parallel with the first vane; wherein the second surface is laterally spaced to the first surface by a first vane length, and the third surface is laterally spaced to the first surface by a second vane length.

First claim

What is claimed is:

1 . An elevator assembly comprising:
an elevator car door configured to be arranged in a door open and a door closed configuration: a coupling assembly operably coupled to the elevator car door, wherein the coupling assembly comprises:
a first vane, including a first surface extending longitudinally vertically to the elevator car door;
a second vane, including a second surface and a third surface extending longitudinally vertically in parallel with the first vane; wherein the second surface is laterally spaced to the first surface by a first coupling length, and the third surface is laterally spaced to the first surface by a second coupling length;
an elevator hoistway door positioned parallel to the elevator car door, the elevator hoistway door configured to operate in concert with the elevator car door in a door open and door closed configuration; and an interlock assembly operably coupled to the elevator hoistway door, wherein the interlock assembly comprises:
a first engaging member; and
a second engaging member laterally spaced from the first engaging member by an engagement length, wherein the first engaging member is configured to engage the first vane and the second engaging member is configured to engage the third surface in the door open configuration.

2 . The elevator assembly of claim 1 , wherein the engagement length is equal to approximately 4.5 inches.

3 . The elevator assembly of claim 1 , wherein the second coupling length is equal to approximately 3.75 inches in a door closed configuration.

4 . The elevator assembly of claim 1 , wherein the second coupling length is equal to approximately 4.92 inches in a door open configuration.

5 . A coupling assembly for an elevator door, the coupling assembly comprising:
a first vane, including a first surface extending longitudinally vertically to the elevator car door; and a second vane, including a second surface and a third surface extending longitudinally vertically in parallel with the first vane; wherein the second surface is laterally spaced to the first surface by a first vane length, and the third surface is laterally spaced to the first surface by a second vane length.

6 . The coupling assembly of claim 5 , wherein the second coupling length is equal to approximately 3.75 inches in a door closed configuration.

7 . The coupling assembly of claim 5 , wherein the second coupling length is equal to approximately 4.92 inches in a door open configuration.

8 . An interlock assembly for an elevator door, the interlock assembly comprising:
a first engaging member; and a second engaging member laterally spaced from the first engaging member by an engagement length, wherein the engagement length is equal to approximately 4.5 inches.
