Abstract

An exemplary mounting arrangement for components of an elevator system comprises a machine support that is configured to support a load associated with an elevator machine. A support for control electronics that operate the elevator machine is connected to the machine support.

First claim

We claim:

1. An elevator system, comprising:
an elevator car;
a machine including a motor, a brake, and a traction sheave;
a roping, arrangement suspending the elevator car, the roping an arrangement at least partially winding about the traction sheave;
a machine support that is configured to support a load associated with an elevator machine, at least a portion of the machine support extending generally horizontally at least partially across a hoistway; and
a support for control electronics that operate the elevator machine, wherein the support for control electronics is situated at least partially outside the hoistway, wherein the support for control electronics includes a housing and vertically oriented rigid members on opposite sides of the housing, and wherein the support for control electronics is connected to the machine support with the vertically oriented rigid members beneath the machine support such that the vertically oriented rigid members support at least a portion of the load of the machine support wherein the support has one end supported on a horizontal surface of a floor near the hoistway.

2. The system of claim 1 , wherein the vertically oriented rigid members of the support for control electronics are configured to be at least partially received on building structure outside of the hoistway.

3. The system of claim 1 , wherein the machine support is permanently connected to the control electronics support.

4. The system of claim 1 , wherein the machine support is removably connected to the control electronics support.

5. The system of claim 1 , wherein the vertically oriented rigid members of the control electronics support comprise at least two side beams adjacent the sides of the housing and the control electronics are at least partially received between the side beams.

6. The mounting arrangement of claim 1 , wherein the vertically oriented rigid members comprise sidewalls of the housing.

7. The mounting arrangement of claim 6 , wherein the vertically oriented rigid members comprise beams adjacent the sidewalls of the housing.

8. A subassembly of an elevator system, comprising:
a machine including a motor, a brake and a traction sheave;
a roping arrangement configured for suspending an elevator car, the roping arrangement at least partially winding about the traction sheave;
control electronics for controlling movement of the elevator system; and
a support situated at least partially within a hoistway and at least partially outside the hoistway, the support having:
a first section receiving said machine, the first section supporting a load associated with the machine, the first section extending generally horizontally at least partially across the hoistway; and
a second section receiving said control electronics and connected to said first section, the second section including vertical members beneath the first section, the second section supporting at least a portion of the load of the machine, the second section being at least partially outside the hoistway wherein the support has one end supported on a horizontal surface of a floor near the hoistway.

9. The subassembly of claim 8 , wherein the support comprises at least two side members and the control electronics can be at least partially received between the side members.

10. An elevator system, comprising:
an elevator car that is moveable within a hoistway;
a machine associated with the elevator car for selectively moving the elevator car within the hoistway, the machine including a motor, a brake and a traction sheave;
a roping arrangement that suspends the elevator car, the roping arrangement at least partially wrapping about the traction sheave;
a machine support that supports a load associated with the machine, the machine support comprising at least a portion extending generally horizontally at least partially across the hoistway;
control electronics for controlling movement of the elevator car;
a support for the control electronics, wherein the control electronics support comprises vertically oriented members beneath the machine support so that the control electronics support at least partially bears the load associated with the machine, the control electronics support being at least partially outside the hoistway; and
a plurality of guide rails, wherein at least one of the guide rails supports a portion of the load of the machine support wherein the support has one end supported on a horizontal surface of a floor near the hoistway.

11. The elevator system of claim 10 , wherein the control electronics support comprises at least two side members and the control electronics can be at least partially received between the side members.

12. The elevator system of claim 10 , wherein the plurality of guide rails include car guide rails, wherein one car guide rail mounts to the machine support and supports a portion of the load of the machine support.
