Definitions

  • the invention relates to an elevator door with a door leaf and with a door sill, the door leaf being guided on the door sill.
  • Known elevator systems include elevator doors which are arranged on floors or an elevator car. Such elevator doors have door leaves which are suspended and driven in the region of their upper edge. The elevator doors still have door sills.
  • the door threshold represents a step area in the area of the door opening.
  • the door leaf is usually guided on this door threshold.
  • a guide groove is arranged in the door sill, into which at least one guide element attached to the door leaf is immersed. When the door leaf opens or closes, the guide element slides within this guide groove provided for this purpose. In this way it can be ensured at any time that the door leaf maintains its preferably vertical orientation, even if, for example, a person is leaning against the door leaf.
  • EP 16465 76 shows an elevator door comprising a door leaf and a door sill. Guide shoes are attached to the lower edge of the door leaf.
  • the door sill has a guide groove. The guide shoes dip into the guide groove in such a way that the door leaf is guided and supported by means of the guide groove.
  • WO2014005890 shows an elevator door comprising a door leaf and a door sill.
  • the door leaf has a lower edge arranged directly on the door sill.
  • a guide shoe is fastened, which can be guided by means of a guide groove formed in the door sill during an opening or closing movement of the door leaf.
  • the door leaf has a guide ruler on its lower edge, which can be guided by means of a tapering in the guide groove.
  • the guide groove is formed in the step surface of the door sill that can be walked on.
  • this leads to contamination of the guide groove by elevator passengers using the elevator system.
  • this tread is designed to be correspondingly uneven, which is an example when goods are rolled in in the elevator car can lead to undesirable vibrations of the goods.
  • the object of the invention is therefore to provide an elevator door with an improved door leaf guide and such a door threshold for this purpose.
  • an elevator door with a door sill, which door sill forms a step surface facing the door opening of the elevator door, and a door leaf, which door leaf can be displaced between its open position and its closed position along a longitudinal alignment of the door sill, the door leaf in its closed position at the same the door sill facing the door leaf closure forms a surface facing the step surface, wherein a door leaf guide groove is formed in this surface parallel to the longitudinal alignment of the door threshold and the door sill comprises a guide piece arranged with respect to the door opening on the side of the step surface, which guide piece engages in the door leaf guide groove for guiding the door leaf, and wherein a guide element is arranged in the region of the door leaf closure facing the door sill and the door leaf arranged in the open position facing the door opening, the first end of the door leaf closure et is, and below the step surface of the door sill a parallel to the longitudinal alignment of the door sill is arranged a threshold guide ruler, the guide element reaching under the door sill through the threshold guide ruler
  • the object is also achieved by means of an elevator system with such an elevator door.
  • a guide device for guiding a door leaf of an elevator door with a door sill, the door leaf being provided for displacement between its open position and its closed position along a longitudinal alignment of the door sill, the door sill forming a step surface which can be turned towards a door opening of the elevator door and which Step surface is provided for arrangement below a door opening that can be formed by the elevator door in its open position, and the door sill comprises a guide piece, which guide piece is provided for engaging a door leaf guide groove of the door leaf for guiding the door leaf and its arrangement with respect to the door opening on the side of the step surface, and Below the step surface of the door threshold, a threshold guide ruler aligned parallel to the longitudinal alignment of the door threshold is arranged, wherein a guide element that can be arranged on the door leaf can be guided through the threshold guide ruler when the door leaf is displaced.
  • the invention is based on the knowledge that such an external influence on the door leaf by a person on the floor or in the elevator car can only take place on the area of the door leaf that is visible from the floor or from the elevator car. Accordingly, it is necessary to mount the door leaf closure facing the door threshold, on the one hand, in the area at the first end of the door leaf closure facing the door opening and, on the other hand, on the side of the step surface. Consequently, when the elevator door is opened or closed and the door leaf is displaced, the part of the door leaf that is freely accessible from the elevator car or floor can only be exposed to external influence by elevator passengers in the area of the door opening.
  • a shortened door threshold is realized by means of the guide piece provided for engagement in the door leaf guide groove. This means that the guide piece guides the door leaf directly adjacent to the vertical alignment of the vertical door opening width.
  • this guide piece enables the door leaf guide groove that can be integrated into the door leaf to be hidden or concealable for the elevator passenger.
  • such a guide piece provided for guidance in the door leaf guide groove of the door leaf has the advantage that the opening of the door leaf guide groove is oriented downward within the elevator system. This has the effect that the risk of contamination of the door leaf guide groove and thus the risk of the elevator door being disturbed by increased friction during operation during an opening or closing movement of the door leaf can be largely avoided.
  • the door opening is a plane parallel to the door leaf, which plane is located within, at least partially within, the volume of the door leaf in its closed position.
  • the guide element has a maximum dimension of 130 mm, which is aligned parallel to the longitudinal orientation of the door sill. It is advantageous here that a section of the door sill arranged laterally of the door opening in the longitudinal direction of the door sill can be made short. In this way, material and space can be saved.
  • the sill guide ruler and the door sill are integrally formed. In this way, a simplified assembly of the door threshold or the elevator door can be made possible.
  • the threshold guide ruler is designed or can be designed along the entire width, preferably at least along the entire width of the door opening. This enables the door leaf to be guided or the guide element arranged on the door leaf to be guided between the closed and open positions of the door leaf.
  • the door leaf guide groove is formed or can be formed essentially along the entire width of the door leaf. Is beneficial accordingly that the guide element is suitable for guiding the door leaf between its open and closed position.
  • the guide piece is or can be arranged to the side of the step surface at a maximum of 0.2 m with respect to the door opening. This means that the guide piece has a maximum distance of 0.2 m in the longitudinal direction of the door threshold in alignment with the step surface.
  • the guide piece preferably directly adjoins the step surface. In this way it is possible that the door threshold only has a reduced space requirement.
  • a further development of the elevator system comprises a car door or a shaft door, the car door or the shaft door being formed by such an elevator door.
  • an elevator car that includes the car door is arranged vertically displaceably in the elevator shaft. Accordingly, the horizontal cross section of the elevator car is to be kept free of any components of the elevator installation or objects over the entire height of the elevator shaft in order to enable the elevator car to be moved.
  • the car door While the elevator car is moving in the elevator shaft, the car door is closed, the door sill, which is horizontally aligned below the door opening, essentially only extending below the at least one door leaf which is in its closed position. It follows from this, by designing such an elevator door as a car door, that the area of the horizontal cross section of the elevator car and thus the volume of the elevator shaft can be minimized or used more efficiently.
  • the volume of the elevator shaft can also be minimized or used more efficiently if the elevator door is designed as a shaft door, so that the door sill is arranged or can be arranged essentially completely below the at least one door leaf of the shaft door that is in its closed position.
  • FIG. 1 shows an elevator system 2.
  • the elevator system 2 comprises an elevator shaft 4 and an elevator car 6 that can usually be moved vertically along the elevator shaft 4 and a counterweight 8 that can be moved in the opposite direction to the elevator car 6.
  • the elevator car 6 and the counterweight 8 are connected by means of a support element 10.
  • the support element 10 can be guided over at least one deflection roller 12, 14, wherein one of these deflection rollers 12, 14 can be designed as a drive roller 12 of the elevator system 2 connected to a drive unit.
  • the elevator shaft 4 has several shaft door openings, which are usually arranged vertically one above the other in accordance with the movability of the elevator car 6. These shaft door openings allow access to the interior of the elevator shaft 4 or the elevator car 6 from floor floors 19a-d.
  • a shaft door 18 which can be assigned to the floor 19a-d is arranged on each of these shaft door openings.
  • the elevator car 6 comprises a car door 16. By moving the elevator car 6 in the elevator shaft 4, the car door 16 can be arranged on one of the shaft doors 18.
