Abstract

An elevator arrangement for an elevator includes a hoisting machine and a maintenance panel. The hoisting machine is arranged in an elevator hoistway, and configured to move an elevator car within the elevator hoistway via a hoisting rope arrangement. The maintenance panel includes components for at least one of control and service of at least one operation of the elevator arrangement. The maintenance panel is configured to slide out from a landing wall into a landing doorway of the elevator arrangement.

First claim

What is claimed is:

1. An elevator arrangement for an elevator, the elevator arrangement comprising:
a hoisting machine in an elevator hoistway, the hoisting machine being configured to move an elevator car within the elevator hoistway via a hoisting rope arrangement;
a first maintenance cabinet within the elevator hoistway, the first maintenance cabinet including components, each of the components included in the first maintenance cabinet being accessible and serviceable only after the elevator is shutdown; and
a second maintenance cabinet within a landing wall of the elevator hoistway, the second maintenance cabinet including a maintenance panel, which further includes electrical components,
wherein the second maintenance cabinet and the maintenance panel are outside the elevator hoistway;
wherein the maintenance panel is accessible while the elevator is in operation;
wherein the maintenance panel is configured to slide out from the landing wall into a landing doorway of the elevator arrangement in a direction substantially parallel to a sliding direction of elevator doors of the elevator, the maintenance panel being arranged such that the electrical components face outward from the elevator doors toward a landing side of the elevator arrangement;
wherein the maintenance panel is configured to slide entirely within the landing wall in a direction substantially parallel to the landing wall and the sliding direction of the elevator doors;
wherein each of the electrical components included in the maintenance panel are accessible and serviceable while the elevator is in operation;
wherein the second maintenance cabinet further includes
an upper cabinet having an upper cabinet door, and
a lower cabinet having a lower cabinet door;

wherein the maintenance panel is arranged in the lower cabinet;
wherein the upper cabinet is accessible only through the upper cabinet door from among the upper cabinet door and the lower cabinet door;
wherein the lower cabinet is accessible only through the lower cabinet door from among the upper cabinet door and the lower cabinet door; and
wherein the upper and lower cabinets are accessible separately and independently from one another.

2. The elevator arrangement of claim 1 , wherein the maintenance panel is accessible from a landing of the elevator.

3. The elevator arrangement of claim 1 , further comprising:
a brake release in the second maintenance cabinet.

4. The elevator arrangement of claim 3 , wherein the brake release is one of a manual brake release and an electric brake release.

5. The elevator arrangement of claim 1 , wherein the second maintenance cabinet is arranged entirely within the landing wall.

6. The elevator arrangement of claim 1 , wherein the first maintenance cabinet includes high voltage components of the elevator.

7. The elevator arrangement of claim 6 , wherein the high voltage components include at least one of an elevator drive system, an autotransformer, a rectifier board, an emergency brake circuit and a toroid.

8. The elevator arrangement of claim 1 , wherein the first maintenance cabinet is fixed in an upper portion of a hoistway wall of the elevator hoistway.

9. The elevator arrangement of claim 1 , wherein the upper cabinet includes disconnect switches, a display, a brake release, and an LED indicator light.

10. The elevator arrangement of claim 9 , wherein the disconnect switches, the display, the brake release, and the LED indicator light are immovably fixed in the upper cabinet.

11. The elevator arrangement of claim 1 , wherein the electrical components include at least one of,
a switch module bypass,
a traction loss switch,
a central processing unit,
an advance door opening board circuit,
a voltage to current board,
gateway boards,
emergency terminal speed limiting boards, and
input/output boards.

12. The elevator arrangement of claim 11 , wherein the maintenance panel further includes at least one of,
optional boards and a repeater.

13. The elevator arrangement of claim 1 , wherein each of the upper cabinet and lower cabinet are accessible while the elevator is in service.

14. The elevator arrangement of claim 1 , wherein the second maintenance cabinet further comprises:
slide rails mounted inside the second maintenance cabinet, the maintenance panel being fixed to the slide rails inside the second maintenance cabinet, wherein
the slide rails are configured such that the maintenance panel slides laterally outward from the landing wall in a plane parallel to a plane of the landing wall.

15. The elevator arrangement of claim 1 , wherein the maintenance panel is configured to be manually slid out from the landing wall using a handle.

16. The elevator arrangement of claim 1 , wherein the electrical components include all electrical components of the elevator that are accessible and serviceable while the elevator is in service.

17. The elevator arrangement of claim 1 , wherein the maintenance panel is configured to slide out from the lower cabinet into the landing doorway on the landing side in front of the elevator doors of the elevator.

18. An elevator arrangement for an elevator, the elevator arrangement comprising:
a hoisting machine in an elevator hoistway, the hoisting machine being configured to move an elevator car within the elevator hoistway via a hoisting rope arrangement; and
a maintenance cabinet including a maintenance panel, the maintenance panel including components for at least one of control and service of at least one operation of the elevator arrangement, the maintenance panel being configured to slide out from a landing wall into a landing doorway of the elevator arrangement in a direction substantially parallel to a sliding direction of elevator doors of the elevator;
wherein the maintenance panel is arranged such that the components face outward from the elevator doors toward a landing side of the elevator arrangement,
wherein the maintenance panel is configured to slide into the landing wall in a direction substantially parallel with the landing wall and the sliding direction of the elevator doors;
wherein when positioned within the landing wall, the maintenance panel is inside the maintenance cabinet and outside of the elevator hoistway;
wherein the maintenance cabinet further includes
an upper cabinet having an upper cabinet door, and
a lower cabinet having a lower cabinet door;

wherein the maintenance panel is arranged in the lower cabinet;
wherein the upper cabinet is accessible only through the upper cabinet door from among the upper cabinet door and the lower cabinet door;
wherein the lower cabinet is accessible only through the lower cabinet door from among the upper cabinet door and the lower cabinet door; and
wherein the upper and lower cabinets are accessible separately and independently from one another.
