Abstract

Example embodiments relate to an elevator car, including a car spoiler at its top and/or bottom thereof, a car sling with a horizontal frame part on which at least one elevator cabin is supported, and at least one vertically extending spoiler element is located aside of the horizontal frame part. The spoiler element may have upper and lower flange portions, at least one of the upper and lower flanges being connected with elevator car parts located above and/or below of the frame part, and a vertically extending middle portion. The spoiler element may be arranged a distance from the frame part. An elevator car having this arrangement may reduce noise and provide better efficiency.

First claim

What is claimed is:

1. An elevator car having side portions, a top portion and a bottom portion, the elevator car comprising:
a spoiler on at least one of the top portion and the bottom portion of the elevator car,
a car sling with a horizontal frame part on which the elevator car is supported thereon, and
a plurality of spoiler elements on a first side of the side portions of the elevator car, at least one of the spoiler elements covering at least a first part of the horizontal frame part, the first side not being one of the side portions of the elevator car with elevator doors, the spoiler elements being arranged side by side with respect to each other, each of the spoiler elements including an upper flange portion, connecting portions, and a lower flange portion, the connecting portions including a first connecting portion and a second connecting portion, the first connecting portion connected to the upper flange portion, the second connecting portion connected to the lower flange portion, wherein
at least one of the upper flange portion and the lower flange portion is connected with the elevator car located above and/or below the horizontal frame part,
the connecting portions are between the upper flange portion and the lower flange portion, and
the connecting portions are tilted away from the first side of the elevator car such that an upper portion of the first connecting portion is closer to the first side of the elevator car than a lower portion of the first connecting portion and a lower portion of the second connecting portion is closer to the first side of the elevator car than an upper portion of the second connecting portion.

2. The elevator car according to claim 1 , wherein the spoiler elements include a flat middle portion.

3. The elevator car according to claim 1 , wherein connecting portions are tilted with respect to a vertical direction of about 10 to 45 degrees away from the first side of the elevator car.

4. The elevator car according to claim 1 , wherein
the spoiler of the elevator car is located at least one of above and below the spoiler elements, and
the spoiler elements are connected to the spoiler.

5. The elevator car according to claim 1 , wherein
the elevator car is above or below another elevator car,
only one of the upper flange portion and the lower flange portion of the spoiler elements is connected to one of the elevator car and the another elevator car, and
one of the upper flange portion and the lower flange portion abuts against a part of one of the elevator car and the another elevator car.

6. The elevator car according to claim 5 , wherein
only the upper flange portion of the spoiler elements is connected to an upper one of the elevator car and the another elevator car, and
the lower flange portion abuts against at least one of the side portions and a spoiler plate of a lower one of the elevator car and the another elevator car.

7. The elevator car according to claim 1 , wherein the elevator car is supported on the horizontal frame part via a spring device.

8. The elevator car according to claim 1 , wherein the horizontal frame part is a sling platform.

9. The elevator car according to claim 1 , wherein the upper flange portion and the lower flange portion of the spoiler elements extend vertically.

10. The elevator car according to claim 9 , wherein the upper flange portion and the lower flange portion of the spoiler elements are flat.

11. The elevator car according to claim 1 , wherein the elevator car is cladded at least on one of the side portions of the elevator car with a vertically extending spoiler plate.

12. The elevator car according to claim 11 , wherein the spoiler elements are connected to the spoiler plate.

13. The elevator car according to claim 1 , wherein the spoiler elements are made from a sheet metal plate.

14. The elevator car according to claim 1 , wherein the middle portion of the spoiler elements is offset with respect to at least one of the upper flange portion and the lower flange portion horizontally away from the elevator car.

15. An elevator comprising:
the elevator car according to claim 1 .

16. The elevator car according to claim 1 , further comprising:
a front spoiler element on a second side of the side portions adjacent to the first side of the side portions, the front spoiler element covering at least a second part of the horizontal frame part, at least a portion of the front spoiler element being below a cabin of the elevator car.
