Definitions

  • the invention relates to a cabin protection device for a cabin of an elevator installation. If a cabin of an elevator system stops at a floor of a building, the cabin floor and the floor of the floor should be flush so as to allow passengers to get out of the cabin as comfortably and safely as possible. However, if the car comes to a stop above the floor of the floor, a vertical opening is formed between the car floor and the floor of the floor and there is a risk of people falling into the elevator shaft. Further, for example, a fire that has broken out in a lower floor could roll over to the upper floor through the opening between the cabin floor and the floor of the storey.
  • a cabin skirt below the cabin door which projects downwards in the vertical direction, ie in the direction of the shaft bottom, and thus closes the possible opening between the cabin floor and the floor of the storey.
  • a cabin apron has for example a dimension of 2 m 2 .
  • the elevator shaft or pit must be deep enough to accommodate the cabin apron when the cabin is at its lowest position.
  • the possibilities for excavating a correspondingly deep shaft pit are not given or at least limited.
  • a telescopic apron which consists for example of three telescoping panels in the vertical direction.
  • WO 2013/054321 discloses a cabin protection device for a cabin of an elevator system, comprising at least one cabin apron which is pivotally connected to the car about a horizontal axis and extends in its folded position vertically downwards and in its Einklappposition obliquely or horizontally below the car floor, and a flap means, the a trigger bar, which is mounted with a horizontal distance to the horizontal axis and down to the shaft bottom extending so long that when the cabin apron is in its Ausklappposition and the shaft base just barely touched, with the trigger rod of the shaft base by moving the cabin in the direction of the shaft base is contactable, and at least one transmission that within the horizontal distance between the trigger bar and the cabin apron is arranged and these coupled to each other, so that when approaching the cabin to the shaft bottom of the trigger rod contacted this, by continuing to drive the cabin toward the shaft bottom of the shaft base via the trigger rod and the transmission of the cabin apron of the Ausklappposition can be brought into the folding position, whereby
  • the object of the invention is to provide a car protection device for a cabin of an elevator installation, wherein the Elevator system is safe to operate and yet the shaft pit needs to be made only flat and the car protection device is low maintenance and reliable.

  • the elevator system is intended for a building in which a corresponding elevator shaft is installed, in which the elevator system is housed.
  • the elevator shaft extends from the basement of the building to its top floor, so that with the elevator system each floor of the building can be reached.
  • the cabin in the elevator shaft move vertically, wherein the cabin can be stopped in each floor so that the cabin floor is flush with the respective floor floor.
  • the cabin in one of the floors comes to a halt such that the cabin floor is arranged above this floor, an opening remains between the cabin floor and the floor of the floor, through which the elevator shaft is accessible from the floor.
  • the fact that the cabin apron is in its Ausklappposition as soon as the trigger rod no longer contacts the shaft base, the opening is covered by the cabin apron.
  • the cabin in the elevator shaft moves down to drive to the basement, the cabin approaches the shaft bottom.
  • the cabin apron is moved from its folded-out position into its folded-in position when the cabin is moved further in the direction of the shaft bottom. Due to the fact that the release rod has a longer extension downwards than the cabin apron, a collision of the cabin apron with the shaft base is prevented. Otherwise, the pit would have to be made deeper, which would then provide sufficient space for the cabin apron in the Ausklappposition. Due to the cab protection device according to the invention, it is rather possible to perform the pit only flat, which is structurally advantageous.
  • the car protection device is independently operable independently of any external power supply, whereby the car protection device is simple and reliable and only requires a low maintenance required.

  • the transmission advantageously has few and functionally reliable components, whereby the maintenance of the car protection device is low.
  • the folding protection device preferably has two cabin skirts facing one another and one of the traction means for each of the cabin aprons, wherein the trigger bar is arranged between the cabin skirts. If the cabin is to be accessible from two opposite sides from one floor, the two cabin skirts located opposite one another enable safe operation of the elevator installation. The fact that only a single release rod is provided for the two cabin aprons, the structure of the cabin protection device is simple and safe in operation.
  • the folding protection device comprises a single cabin apron which is hinged to one side of the cabin, and the trigger bar is arranged on one side opposite the other side, wherein the traction means bridges the distance between the one side and the other side ,

Furthermore, it is preferred that the cabin apron between its articulation on the cabin and the determination of the traction means is rigid. As a result, the cabin protection device according to the invention has a few moving parts, which merely have at least a slight wear.
  • the cabin protection device preferably has a locking device with which the cabin apron can be locked in its folded-in position and / or in its folded-out position. This prevents that when the cabin apron covers an opening between the cabin floor and a storey floor, the cabin apron can be pressed into the elevator shaft approximately.
