Abstract

An elevator car door system is provided, the system including an elevator car door panel (502, 600, 704) having a first retention member (510, 604, 720) and a suspension (504, 602, 706) having a second retention member (512, 606, 718) configured to releasably engage with the first retention member (510, 604, 720) to retain the elevator car door panel (502, 600, 704) in a first position. The elevator car door panel (502, 600, 704) is movable relative to the suspension (504, 602, 706) to a second position, wherein the second position is configured to enable the elevator car door panel (502, 600, 704) to be removed from the suspension (504, 602, 706).

First claim

What is claimed is:

1. An elevator car door system comprising:
an elevator car door panel having a first retention member; and
a suspension having a second retention member configured to releasably engage with the first retention member to retain the elevator car door panel in a first position;
wherein the elevator car door panel is moveable relative to the suspension to a second position, wherein the second position is configured to enable the elevator car door panel to be removed from the suspension.

2. The system of claim 1 , wherein one of the first retention member and the second retention member is at least one fastener.

3. The system of claim 1 , wherein the other of the first retention member and the second retention member is at least one aperture.

4. The system of claim 3 , wherein the at least one aperture includes a first width and a second width, wherein the first width is larger than the second width, and wherein the first width is sized to permit the at least one fastener to pass therethrough and the second width is sized to prevent the at least one fastener to pass therethrough.

5. The system of claim 1 , wherein the first retention member and the second retention member form an electromechanical link between the car door panel and the suspension.

6. The system of claim 1 , wherein the number of first retention members equals the number of second retention members.

7. The system of claim 1 , wherein the first retention member is a locking tie.

8. The system of claim 1 , wherein the suspension further comprises a stop element configured to assist in the placement of the elevator car door panel relative to the suspension.

9. The system of claim 1 , further comprising a locking member configured to secure the elevator car door panel to the suspension in the first position.

10. The system of claim 1 , wherein at least one of the first retention member and the second retention member is accessible from an inside of an elevator car.
