Abstract

An elevator car panel configured to open and methods of opening the same. The elevator car panel includes a handrail configured on a first side of the elevator car panel and a locking mechanism configured on a second side of the elevator car panel, the second side opposite the first side. The handrail is operably connected to the locking mechanism such that movement of the handrail from a first position to a second position operates the locking mechanism to transition from a locked position to an unlocked position and, when in the unlocked position, the elevator car panel is openable.

First claim

What is claimed is:

1. An elevator car panel comprising:
a handrail configured on a first side of the elevator car panel; and
a locking mechanism configured on a second side of the elevator car panel, the second side opposite the first side,
wherein the handrail is operably connected to the locking mechanism such that movement of the handrail from a first position to a second position operates the locking mechanism to transition from a locked position to an unlocked position, and
wherein, when in the unlocked position, the elevator car panel is openable.

2. The elevator car panel of claim 1 , wherein the locking mechanism includes at least one locking pin, the locking pin configured to be engaged with a fixed portion of the elevator car when the locking mechanism is in the locked position and disengaged when the locking mechanism is in the unlocked position.

3. The elevator car panel of claim 2 , further comprising a pivot operably connected to the handrail, wherein the at least one locking pin is operably connected to the pivot.

4. The elevator car panel of claim 3 , further comprising a connector operably connecting the at least one locking pin to the pivot.

5. The elevator car panel of claim 1 , further comprising a securing mechanism configured to secure the handrail in the first position and releasable to enable the handrail to move to the second position.

6. The elevator car panel of claim 1 , further comprising an additional handrail fixedly connected to the elevator car panel.

7. The elevator car panel of claim 1 :
wherein the elevator car panel includes a first subpanel and a second subpanel,
wherein the handrail connected to the locking mechanism is mounted on the first subpanel, and
wherein the first subpanel and the second subpanel form a wall of an elevator car.

8. The elevator car panel of claim 1 , further comprising at least one hinge configured to enable the elevator car panel to open when the locking mechanism is in the unlocked position.

9. The elevator car panel of claim 1 , further comprising at least one translating mechanism configured to enable the elevator car panel to open when the locking mechanism is in the unlocked position.

10. A method of opening an elevator car panel, the method comprising:
operating a handrail of an elevator car panel from a first position to a second position; and
unlocking at least one locking pin of a locking mechanism operably connected to the handrail due to operation of the handrail from the first position to the second position, the at least one locking pin engageable with a fixed portion of the elevator car,
wherein the handrail is on a first side of the elevator car panel and the locking mechanism is on a second side of the elevator car panel opposite the first side.

11. The method of claim 10 , further comprising unlocking the handrail prior to operating the handrail from the first position to the second position.

12. The method of claim 10 , further comprising opening the elevator car panel after unlocking the at least one locking pin.

13. The method of claim 10 , further comprising operating the handrail from the second position back to the first position, and locking the at least one locking pin.

14. The method of claim 10 , wherein operation of the handrail comprises one of rotation, pushing, pulling, or translating.

15. The method of claim 10 :
wherein the elevator car panel includes a first subpanel and a second subpanel,
wherein the handrail connected to the locking mechanism is mounted on the first subpanel, and
wherein the first subpanel and the second subpanel form a wall of an elevator car.
