Abstract

An elevator arrangement, in particular a construction time elevator arrangement, includes a hoistway; an elevator car mounted in the hoistway; and a vertically movable support structure in the hoistway for supporting the elevator car, the movable support structure being mounted above the elevator car in the hoistway. The vertically movable support structure includes a first working platform, having a planar working area, and a protective cover above the first working platform for protecting elevator components and/or people below it from falling objects. The protective cover covers most of the cross section of the hoistway.

First claim

The invention claimed is:

1. An elevator arrangement, comprising:
a hoistway;
an elevator car mounted in the hoistway; and
a vertically movable support structure in the hoistway for supporting the elevator car, the movable support structure being mounted above the elevator car in the hoistway, the vertically movable support structure comprising:
a first working platform, having a planar working area; and
a protective cover above the first working platform for protecting elevator components and/or people below the first working platform from falling objects, the protective cover covering most of the cross section of the hoistway,

wherein the protective cover comprises one or more displaceable cover parts forming part of the periphery of the protective cover, the displaceable cover parts being displaceable for increasing free space beside the protective cover, for creating a gap between the protective cover and an adjacent side wall of the hoistway.

2. The elevator arrangement according to claim 1 , wherein the hoistway has a first side wall, and a second side wall, the elevator car being mounted in the hoistway between the first side wall and the second side wall, a first gap being formed between the car and the first side wall, and a second gap being formed between the car and the second side wall, the protective cover extending over the first and second gap covering most of the cross sectional areas of the first and second gap.

3. The elevator arrangement according to claim 2 , wherein the elevator comprises vertically oriented car guide rails for guiding the movement of the elevator car, said guide rails comprising a first guide rail extending through said first gap, and a second guide rail extending through said second gap.

4. The elevator arrangement according to claim 3 , wherein the protective cover extends in width direction of the hoistway closer to the first side wall than the first guide rail, and closer to the second side wall than the second guide rail.

5. The elevator arrangement according to claim 4 , wherein the protective cover comprises a first opening through which the first guide rail extends, and a second opening through which the second guide rail extends.

6. The elevator arrangement according to claim 3 , wherein the protective cover extends between the first side wall and the first guide rail, covering at least part of the gap formed between the first side wall and the first guide rail, and/or between the second side wall and the second guide rail, covering at least part of the gap formed between the second side wall and the second guide rail.

7. The elevator arrangement according to claim 6 , wherein the car guide rails extend continuously from below the vertically movable support structure above the vertically movable support structure.

8. The elevator arrangement according to claim 3 , wherein the car guide rails extend continuously from below the vertically movable support structure above the vertically movable support structure.

9. The elevator arrangement according to claim 3 , wherein the protective cover comprises a first opening through which the first guide rail extends, and a second opening through which the second guide rail extends.

10. The elevator arrangement according to claim 1 , wherein said one or more displaceable cover parts of the protective cover include one or more displaceable cover parts, which extend over the first gap and/or over the second gap.

11. The elevator arrangement according to claim 1 , wherein the one or more displaceable cover parts include a displaceable cover part extending between the first side wall and the first guide rail covering at least part of the gap formed between the first side wall and the first guide rail, and/or a displaceable cover part extending between the second side wall and the second guide rail and covering at least part of the gap formed between the second side wall and the second guide rail.

12. The elevator arrangement according to claim 1 , wherein the one or more displaceable cover parts include in depth direction of the hoistway on both sides of the first guide rail, a displaceable cover part extending in a width direction of the hoistway closer to the first side wall than the first guide rail, and/or the one or more displaceable cover parts include in depth direction of the hoistway on both sides of the second guide rail, a displaceable cover part extending in the width direction of the hoistway closer to the second side wall than the second guide rail.

13. The elevator arrangement according to claim 1 , wherein the protective cover comprises a second working platform, the protective cover being provided with a balustrade bordering a planar working area of the second working platform.

14. A method comprising the steps of:
providing an elevator arrangement as defined in claim 1 ; and thereafter
using the elevator car for transporting passengers and/or goods; and thereafter
hoisting the movable support structure higher in the hoistway; and thereafter
using the elevator car again for transporting passengers and/or goods.

15. The method according to claim 14 , wherein the method comprises, after said using and before said hoisting, displacing one or more displaceable cover parts of the protective cover for increasing free space beside the protective cover.

16. The method according to claim 15 , wherein said displacing comprises displacing one or more displaceable cover parts of the protective cover, the one or more displaceable cover parts extending over the first and/or second gap.

17. The method according to claim 15 , wherein said displacing comprises displacing a displaceable cover part extending between the first side wall and the first guide rail covering at least part of the gap fainted between the first side wall and the first guide rail, and/or displacing a displaceable cover part extending between the second side wall and the second guide rail and covering at least part of the gap formed between the second side wall and the second guide rail.

18. The elevator arrangement according to claim 4 , wherein the protective cover extends between the first side wall and the first guide rail, covering at least part of the gap formed between the first side wall and the first guide rail, and/or between the second side wall and the second guide rail, covering at least part of the gap formed between the second side wall and the second guide rail.

19. The elevator arrangement according to claim 4 , wherein the car guide rails extend continuously from below the vertically movable support structure above the vertically movable support structure.
