Abstract

A car for an elevator, which is movable in an elevator shaft, has a car roof projecting at least partly beyond a drive unit. Arranged on the car roof in the region of the side facing the drive unit is a balustrade which has a handrail interrupted centrally in a drive receiving region. The balustrade has in the drive receiving region a bar which is arranged to be offset downwardly and inwardly relative to the handrail.

First claim

The invention claimed is:

1. An elevator with a car movable in an elevator shaft and having a car roof, a drive unit for moving the car, the drive unit being arranged in a region of a shaft head in the elevator shaft and projecting at least partly over the car roof, comprising:
a balustrade arranged on the car roof adjacent an edge of the car roof at a side of the car facing toward the drive unit, the balustrade including a horizontally extending handrail that has formed therein an interruption that is configured to receive a portion of the drive unit when the car is positioned at the shaft head and further including a bar connected directly to the balustrade, extending horizontally completely across the interruption and being positioned below at least one handrail section of the handrail.

2. The elevator according to claim 1 wherein the bar is offset inwardly-relative to the handrail away from the side of the car facing toward the drive unit.

3. The elevator according to claim 1 wherein the balustrade includes at least one intermediate rod positioned between the at least one handrail section and the car roof and extending parallel to the bar.

4. The elevator according to claim 3 wherein the at least one intermediate rod is positioned at approximately half a height of the handrail.

5. The elevator according to claim 3 wherein the bar is positioned higher relative to the car roof than the at least one intermediate rod.

6. The elevator according to claim 1 wherein the balustrade includes a first inner post and a second outer post positioned on one side of the interruption and the at least one handrail section extends between the first inner post and the second outer post, wherein the balustrade includes a second inner post and a second outer post positioned on an opposite side of the interruption and another handrail section that extends between the second inner post and the second outer post, and wherein the interruption lies between the first and second inner posts and the bar is fastened to the first and second outer posts.

7. The elevator according to claim 6 wherein the bar is connected with the first and second outer posts by respective spacer members.

8. The elevator according to claim 7 wherein the spacer members extend transverse to the bar.

9. The elevator according to claim 1 including a support means in operative connection with the drive unit for supporting the car, the support means being guided in vertical direction along a shaft wall of the elevator shaft at which the drive unit is positioned, and wherein the interruption is aligned with the support means.

10. The elevator according to claim 1 including at least one guide rail arranged at a shaft wall of the elevator shaft at which the drive unit is positioned for guiding at least one of the car and a counterweight, and wherein the interruption is aligned with the at least one guide rail.

11. A car for an elevator, the car being movable in an elevator shaft by a drive unit being arranged in a region of a shaft head in the elevator shaft, comprising:
a car roof of the car wherein the drive unit projects at least partly over the car roof; and
a balustrade positioned on the car roof adjacent an edge of the car roof at a side of the car facing toward the drive unit, the balustrade having a handrail with an interruption formed therein, the interruption being configured to receive a portion of the drive unit when the car is positioned at the shaft head, and the balustrade having a bar connected directly to the balustrade, extending horizontally completely across the interruption and offset downwardly relative to the handrail.

12. The car according to claim 11 wherein the bar is offset inwardly relative to the handrail away from the side of the car facing toward the drive unit.

13. The car according to claim 11 wherein the balustrade includes a pair of intermediate rods positioned on opposite sides of the interruption, each of the intermediate rods being positioned between the handrail and the car roof and extending parallel to the bar.

14. The car according to claim 13 wherein the intermediate rods are positioned at approximately half a height of the handrail above the car roof.

15. The elevator according to claim 13 wherein the bar is positioned higher relative to the car roof than the intermediate rods.

16. An elevator with a car movable in an elevator shaft and having a car roof, a drive unit for moving the car, the drive unit being arranged in a region of a shaft head in the elevator shaft and projecting at least parily over the car roof, comprising:
a balustrade arranged on the car roof adjacent an edge of the car roof at a side of the car facing toward the drive unit, the balustrade including,
a horizontally extending handrail that has formed therein an interruption that is configured to receive a portion of the drive unit when the car is positioned at the shaft head,
a bar extending across the interruption and being positioned below at least one handrail section of the handrail,
a first inner post and a second outer post positioned on one side of the interruption and the at least one handrail section extending between the first inner post and the second outer post,
a second inner post and a second outer post positioned on an opposite side of the interruption and another handrail section that extends between the second inner post and the second outer post, and
wherein the interruption lies between the first and second inner posts and the bar is fastened to the first and second outer posts.

17. The elevator according to claim 16 wherein the bar is connected with the first and second outer posts by respective spacer members.

18. The elevator according to claim 17 wherein the spacer members extend transverse to the bar.
