Definitions

  • the invention relates to a safety device for an elevator car according to the first independent claim.
  • Today roof windows are variously provided in the elevator car in the elevator car, which serve as mounting hatch, or which are intended as an emergency exit.
  • a corresponding rescue device is the Japanese patent publication number 2001171932 A refer to.
  • a device which contains a foldable ladder, which is housed in a roof hatch of the elevator car. If passengers want to leave the elevator car in an emergency, they must fold out the ladder and open the skylight. If a rescue team wants to enter the cabin from the outside, the hatch must first be opened from the roof of the canopy, in order to be able to fold out the ladder. It is a disadvantage of this device that the roof hatch together with ladder is relatively heavy, which makes it difficult to open from the outside.
  • a maintenance device with ladder and skylight is the European patent EP 870722 B1 refer to.
  • a ladder is arranged on the car roof of the elevator car, with which a fitter can reach and maintain facilities on the roof of the cabin from the inside of the cabin ago.
  • This ladder is folded into the cabin after opening the roof hatch or pulled out telescopically.
  • This solution is like this It has been chosen that only a fitter can open the skylight with a key or a tool to gain access to the ladder.
  • the approach shown is not suitable because on the one hand keys or tools are needed to open the hatch and on the other hand, the ladder on the cabin roof from the interior of the cabin can only be reached with tools or with appropriate body size.
  • EP 870722 B1 is considered to be the closest prior art for the present invention.
  • the elevator car has inside a suspended ceiling panel, which extends at a distance parallel to the cabin ceiling. There is a gap between the cabin ceiling and the ceiling cladding. A telescopic ladder is stowed in this space and attached folded down in the cabin ceiling.
  • FIGS. 1 and 2 a first embodiment of the invention is shown.
  • a section through an elevator shaft 11 of an elevator installation 10 is shown.
  • An elevator car 12 is located in the elevator shaft 11 just below a floor E with a shaft door 13.
  • the elevator car 12 has a cabin floor 19 and a car ceiling 14.
  • the cabin ceiling 14 is not visible from the interior of the elevator car 12 since it is suspended by a ceiling panel 16.
  • the cabin lighting can be integrated, or the cabin lighting can be arranged in the space between the car ceiling 14 and ceiling panel 16.
  • the ceiling panel 16 extends parallel to the cabin ceiling 14 and has a clear distance A, which is less than 20 cm, and preferably about 10 cm.
  • a roof hatch 15 is provided, which can be opened after the operation of a pawl or a button upwards, as indicated by an arrow.
  • the roof hatch 15 is shown in the open position.
  • it is also an arrangement providable with a roof hatch 15, which can be opened in the interior of the elevator car 12.
  • the advantage of such an arrangement is that the roof hatch 15 swings down by gravity and accordingly less force has to be expended for opening the roof hatch 15.
  • This opening of the roof hatch 15 can thus be a folding outwards or inwards. For space-saving reasons, it will open a separate figure for the second also possible embodiment omitted.
  • a telescopic conductor 17 is now arranged in said space.
  • This telescopic ladder 17 is attached folded down in the area of the cabin ceiling 14.
  • an attachment by means of hinges 18 is shown.
  • the telescopic ladder 17 can be folded down as indicated by an arrow in FIG Fig. 1 indicated.
  • After folding down the telescopic ladder 17 hangs on the hinges 18. It can now be pulled out the individual bars step by step and the individual treads are locked. Importantly, these steps are manual and easy to do. So no tools are needed.
  • the ceiling cladding 16 In order to get access to the telescopic ladder 17 and roof hatch 15 from the interior of the elevator car 12, the ceiling cladding 16 must be opened completely or partially.
  • the ceiling panel 16 or a part of the same, but can also be removed from an anchorage and parked on a cabin wall. It is also possible a part 16.1 of the ceiling panel 16, as with suspended Ceilings in buildings common to push on another part of the ceiling paneling.
  • the opening or removal of the ceiling panel 16 is done manually, i. No tools needed.
  • Fig. 2 is the state after opening or removing the ceiling panel 16, after folding down and telescopically extending the telescopic ladder 17 in the interior of the elevator car 12 and after opening the roof hatch 15 shown.
  • a tread area T is preferably provided, which can absorb the forces occurring.
  • the tread area T is preferably specially marked, e.g. with fluorescent paint or corresponding stickers.
  • FIG. 3 A presently preferred embodiment of the invention is in Fig. 3 shown.
  • This embodiment is characterized in that the telescopic ladder 17 is fixed to the cabin ceiling 14 so that it can be unhooked. Then the telescopic ladder 17 can be lifted onto the cabin ceiling 14. With the telescopic ladder 17 on the cabin ceiling 14 distances of up to 3 m to the next floor E can be bridged.
  • the hinge 18.1 can be designed to be open, as in FIG. 3 indicated.
  • the hinge 18.1 may, for example, have an obliquely extending from top right to bottom left slot.
  • the telescopic ladder 17 hangs at the lowest point of the slot. When loosening or removing the telescopic ladder 17, this is pushed out of the slot and can then be placed on the cab roof 14.
  • the safety device is designed so that it can also be operated from above. This is important if a rescue team wants to enter the cabin from outside, for example, to rescue passengers.
  • the roof hatch 15 can be opened from the tread area T ago. Then, the ceiling panel 16, or a part thereof, is removed and the telescopic ladder 17 is unfolded.
  • 15 safety switches are attached to the telescopic ladder 17 and / or the roof hatch. These safety switches should ensure that the elevator car 12 can not be left while driving through the roof hatch 15. Depending on the embodiment of the invention, the triggering of one of the safety switches can trigger an emergency stop of the elevator car 12.
  • an elevator installation whose elevator car 12 comprises means which indicate the emergency exit in the cabin ceiling 14 in an emergency.
  • the ceiling lighting for example, can be designed so that If necessary, it switches to emergency lighting and displays the emergency exit accordingly. But it can also display a screen corresponding instructions, or it can be made a corresponding announcement audible.
