Definitions

  • This invention relates to a lift car for reduced lift shaft heads.
  • many lift drives are located at the top of the lift shaft.
  • a lift mechanic must climb onto the cab roof of the lift cab to gain access to the lift drive. This is fundamentally dangerous, and in the past a number of fitters have been injured or even killed by being crushed while carrying out such inspection and maintenance work between the lift car and the shaft ceiling. Therefore, the legislator has issued strict guidelines that should make crushing impossible.
  • a lift to be installed there has a cabin with an interior height of 220 cm. Approx. 10cm are required for the crossing above the cabin. For the lift door drive, it also requires a certain height. This leaves 50cm left in the top normal lift position. These are required as a safety buffer. If the lift stops with a heavy load on the top floor, exactly at floor level, and then is relieved, the car can still rise a few cm due to the elasticity of the carrying side. Even then, there must still be a wide gap up to the top of the lift shaft so that the lift cabin cannot hit it under any circumstances. In this constellation with a lift cabin height of 220cm plus the minimum height of the prescribed quad lying down of 0.50m, i.e.
  • EP 1 533 265 A shows an elevator car for a reduced elevator headroom, the elevator car having a car roof that lowers and rises. A mechanic can access the lowered roof for maintenance work. Movement of the canopy is accomplished using a winch device.
  • the object of the present invention is therefore to create an elevator car for reduced elevator shaft heads which requires a minimum shaft head height for a specific elevator car height and is nevertheless able to meet the provisions of the elevator ordinance with regard to the clearances against the risk of crushing.
  • the figure 2 shows another conventional lift construction.
  • the lift motor is located further down, not directly above the cross-section of the lift car, but at about the level of the upper edge of the car when the car is in its uppermost position, as shown here.
  • the lift motor must still be serviced from the outside - it is not accessible from inside the cabin.
  • the cuboid 0.5m ⁇ 0.6m ⁇ 0.8m can be on a different side.
  • figure 3 shows an elevator car according to the invention for reduced elevator shaft heads.
  • the lift car has reached the uppermost position as shown, its upper outer edge 2 has completely run over the laterally arranged lift motor 1 , so that the lift motor 1 is located to the side of the lift car 10 .
  • the proportions are significantly different here.
  • this cabin 10 can be driven almost to the upper end of the lift shaft head 11 .
  • Only the height of around 15 to 20 cm for installing the door drives for the lift doors and a few centimeters of buffer zone in the event that the lift cabin is raised a few centimeters due to the elasticity of the carrying cables with the weight relief when people get out must be taken into account.
  • figure 4 shows how maintenance work can be carried out on this lift construction.
  • a part 3 of the side wall of the cabin 10 is removed inwards into the cabin 10 and placed in front of the lower part 6 of the side wall.
  • this removable side wall part 3 is placed at a certain distance in front of the lower side wall part 6 .
  • the distance is maintained by spacers 12 or by a handrail on the lower part 6 of the side wall.
  • the Figure 3 and 4 sees, namely the supporting ropes 7 run very close to the elevator car 10, because the attempt is made to keep the depth of the drive devices as small as possible in order not to waste space in the elevator shaft unnecessarily at the expense of the car width.
  • a regulation requires that the distance from the parapet 4, on which the lift fitter works, up to to the moving parts to be serviced and checked is at least 10 cm. By placing the upper side wall part 3 at a distance, it is ensured that this distance of 10 cm to the next moving parts, namely to the supporting cables but also to the guide rails, which the cabin is driven past for maintenance purposes, is maintained.
  • the roof 9 of the lift cabin 10 can be used as in Figure 3 and 4 shown to be made from a bare metal sheet that is attached to the cabin roof from below by plug-in or clamp connections. As soon as a certain load is exceeded, the connections are released and the roof 9 falls into the elevator car.
  • the roof 9 is, for example, the size of a base area of the required cuboid, i.e. the size 60 cm ⁇ 80 cm, 50 cm ⁇ 60 cm, or 50 cm ⁇ 80 cm, is held by a number of predetermined breaking points on a corresponding hatch in the lift cabin roof. As soon as a certain load acts on the roof 9, the predetermined breaking points break and the roof 9 falls into the elevator car 10.
  • the flexible roof piece can also be attached to ropes, which can be pulled out, for example, with a spring.
  • a spring This can be realized, for example, as in figure 4 shown, namely that the corners of the roof piece hang on wire pulls 13, which are guided over pulleys 14,15 along the outside of the elevator car and are attached to tension springs 16 there.
  • other guides for the cable pulls are also conceivable, so that they only run on the cabin roof.
  • the roof 9 lowers, stretching the springs 16, at least far enough for the required free space F to be available.
  • the flexible roof 9 can also be designed as a foldable roof, in that it is held in a hinged manner on a corresponding hatch in the cabin roof and is held on the side facing away from the hinge via a predetermined breaking point.
  • the roof can also be designed as a wing door, so that two wings hinged on opposite sides of a hatch form the roof. A bolt with a predetermined breaking point closes the door leaves and holds them together until a certain load is exceeded. The two door leaves then fold down.
  • the minimum height of the lift shaft head is still 255cm. This 45cm difference is required by the cabin construction and in particular by the motor drives for the lift doors and by a buffer zone. With even more compact electric motors for the door drives, the headroom height can be further reduced by a few cm, to approx. 240cm.
