Abstract

An elevator cage is movable in an elevator shaft, wherein a ventilating device is fastened to a cage outer surface, wherein this ventilating device forms at least one ventilation channel, wherein the at least one ventilation channel has at least one primary ventilation opening enabling an air exchange between the ventilation channel and the elevator shaft, wherein at least one of the cage outer surfaces has at least one secondary ventilation opening enabling an air exchange between a cage interior space and the at least one ventilation channel, with at least one element of insulating material, and wherein the at least one element substantially determines a path of the at least one ventilation channel.

First claim

We claim:

1. An elevator cage, comprising:
a plurality of outer surfaces delimiting a cage interior space;
a ventilating device fastened to a one of the outer surfaces, the ventilating device including at least one ventilation channel for exchange of air between the cage interior space and an exterior of the elevator cage, the at least one ventilation channel having at least one primary ventilation opening open to the elevator cage exterior, the one outer surface having at least one secondary ventilation opening between the cage interior space and the at least one ventilation channel; and
an insulating element included in the ventilating device and being formed of an insulating material, the insulating element forming a horizontally extending surface of the at least one ventilation channel, the at least one primary ventilation opening and the at least one secondary ventilation opening being positioned at a same height relative to the one outer surface to guide air flow substantially horizontally through the at least one ventilation channel of the ventilating device, wherein the one outer surface is a cage roof and the ventilating device forms a part of a foot strip on the cage roof leaving a portion of the cage roof exposed.

2. The elevator cage according to claim 1 wherein an entirety of the at least one ventilation channel is formed in the insulating element.

3. The elevator cage according to claim 2 wherein the at least one ventilation channel has a rectilinear form.

4. The elevator cage according to claim 2 wherein the at least one ventilation channel is formed by a cut-out in the insulating element.

5. The elevator cage according to claim 4 including at least one support positioned in the cut-out for stabilizing the at least one ventilation channel.

6. The elevator cage according to claim 2 wherein the at least one ventilation channel has a curved form.

7. The elevator cage according to claim 6 wherein the at least one ventilation channel is formed as a bore.

8. The elevator cage according to claim 2 wherein the at least one ventilation channel is formed by a porous region of the insulating element.

9. The elevator cage according to claim 1 wherein the ventilating device includes a cover element, the cover element and the insulating element cooperating to form the at least one ventilation channel.

10. The elevator cage according to claim 9 wherein the cover element and the insulating element are adhesively fastened to the one outer surface.

11. The elevator cage according to claim 1 wherein insulating element is adhesively fixed to the one outer surface.

12. The elevator cage according to claim 1 wherein a cable guide is disposed on the ventilating device.

13. The elevator cage according to claim 1 including a fan positioned at the at least one primary ventilating opening.

14. The elevator cage according to claim 13 wherein the fan is configured to be switched on.

15. The elevator cage according to claim 13 wherein the fan is capable of being used with a computer.

16. An elevator installation, comprising:
an elevator cage disposed in an elevator shaft, the elevator cage having a plurality of outer surfaces delimiting a cage interior space;
a ventilating device fastened to a one of the outer surfaces, the ventilating device including at least one ventilation channel for exchange of air between the cage interior space and an exterior of the elevator cage, the at least one ventilation channel having at least one primary ventilation opening open to the elevator cage exterior, the one outer surface having at least one secondary ventilation opening between the cage interior space and the at least one ventilation channel; and
an insulating element included in the ventilating device and being formed of an insulating material, the insulating element forming a horizontally extending surface of the at least one ventilation channel, the at least one primary ventilation opening and the at least one secondary ventilation opening being positioned at a same height relative to the one outer surface to guide air flow substantially horizontally through the at least one ventilation channel of the ventilating device, wherein the one outer surface is a roof of the elevator cage and the ventilating device forms a part of a foot strip on the cage roof leaving a portion of the cage roof exposed.

17. The elevator installation according to claim 16 wherein another of the outer surfaces is a floor of the elevator cage, and including another one of the ventilating device fastened to the elevator cage floor.
