Elevator car ceiling access system
Elevator car ceiling access systems are provided. The elevator car ceiling access systems include an elevator car having a top and at least one elevator car door, an access panel located in a top of the elevator car, a car door operator, an access panel operator, and a selectively engageable coupling arranged between the car door operator and the access panel operator and arranged to selectively couple to the car door operator and the access panel operator to enable selective opening of the access panel.
1. An elevator car ceiling access system comprising:
an elevator car having a top and at least one elevator car door;
an access panel located in a top of the elevator car;
a car door operator;
an access panel operator; and
a selectively engageable coupling arranged between the car door operator and the access panel operator and arranged to selectively couple to the car door operator and the access panel operator to enable selective opening of the access panel.
2. The elevator car ceiling access system of claim 1 , wherein the car door operator includes a pulley and a door operator cable operably connected to the pulley of the car door operator.
3. The elevator car ceiling access system of claim 1 , wherein the selectively engageable coupling includes a first electromagnet arranged proximate to the car door operator and a second electromagnet arrange proximate the access panel operator, wherein the first and second electromagnets are arranged to selectively control engagement with the car door operator and the access panel operator.
4. The elevator car ceiling access system of claim 1 , wherein the access panel is hingedly connected to the top of the elevator car.
5. The elevator car ceiling access system of claim 1 , further comprising a lock arranged to selectively secure the access panel in a closed position.
6. The elevator car ceiling access system of claim 5 , wherein the lock includes an electrically driven lock driver and a lock pin, wherein, in a closed state, the lock pin engages with a locking bracket of the access panel.
7. The elevator car ceiling access system of claim 1 , wherein the selectively engageable coupling is electrically connected to a control panel to enable selective operation of the selectively engageable coupling.
8. The elevator car ceiling access system of claim 7 , wherein the control panel is a car operating panel of the elevator car.
9. An elevator car ceiling access system comprising:
an elevator car having a top and at least one elevator car door;
an access panel located in a top of the elevator car;
a car door operator;
an access panel operator; and
a selectively engageable coupling arranged between the car door operator and the access panel operator and arranged to selectively couple to the car door operator and the access panel operator to enable selective opening of the access panel,
wherein the access panel operator includes a first pulley, a second pulley, and an access panel cable operably connecting the first pulley to the access panel.
10. The elevator car ceiling access system of claim 9 , further comprising a lock arranged to selectively secure the access panel in a closed position.
11. The elevator car ceiling access system of claim 10 , wherein the lock includes an electrically driven lock driver and a lock pin, wherein, in a closed state, the lock pin engages with a locking bracket of the access panel.
12. The elevator car ceiling access system of claim 9 , wherein the selectively engageable coupling is electrically connected to a control panel to enable selective operation of the selectively engageable coupling.
13. The elevator car ceiling access system of claim 12 , wherein the control panel is a car operating panel of the elevator car.
14. The elevator car ceiling access system of claim 9 , wherein the access panel is hingedly connected to the top of the elevator car.
15. The elevator car ceiling access system of claim 14 , wherein a pulley of the access panel operator is attached to the drive shaft.
16. The elevator car ceiling access system of claim 15 , further comprising a first coupling element arranged to selectively couple with the car door operator and a second coupling element arranged to selectively couple with the access panel operator.
17. The elevator car ceiling access system of claim 14 , further comprising a first coupling element arranged to selectively couple with the car door operator and a second coupling element arranged to selectively couple with the access panel operator.
18. The elevator car ceiling access system of claim 17 , wherein at least one of the first coupling element and the second coupling element comprises an armature and a friction ring.
19. An elevator car ceiling access system comprising:
an elevator car having a top and at least one elevator car door;
an access panel located in a top of the elevator car;
a car door operator;
an access panel operator; and
a selectively engageable coupling arranged between the car door operator and the access panel operator and arranged to selectively couple to the car door operator and the access panel operator to enable selective opening of the access panel,
wherein the selectively engageable coupling includes a motor and drive shaft arranged to selectively drive operation of car door operator and access panel operator.
20. The elevator car ceiling access system of claim 19 , wherein the access panel is hingedly connected to the top of the elevator car.
