Definitions

  • the invention relates to an elevator installation according to the preamble of claim 1.
  • Elevator systems for transporting people and goods contain cabins that can be moved up and down in an elevator shaft.
  • the cabins can be moved by means of suspension means, for example in the form of suspension ropes or suspension belts, by means of a drive unit.
  • suspension means for example in the form of suspension ropes or suspension belts
  • the car can get stuck between the floors.
  • the trapped people must be evacuated from the cabin to the next stop.
  • the cabins are equipped with cabin aprons.
  • For the elevator industry there are various sets of rules with precise specifications for the design of car aprons. Rigid cabin aprons have been known and used for a long time.
  • the elevator installation comprises an elevator shaft and a car that can be moved up and down in the elevator shaft, preferably along guide rails.
  • the cabin has a movable cabin apron, wherein the cabin can be moved between a horizontal rest position and a vertical locking division.
  • the cabin apron is, when it is in the barrier division, can be supported on one of the shaft doors.
  • Movable car aprons are particularly advantageous for elevator systems with low pit depths or for pitless elevators. For the access of passengers and goods to the cabin, landing doors can be provided on each floor.
  • the cabin apron is designed in such a way that, when it is in the blocking position, when horizontal forces are exerted from the outside by people exiting the cabin interior can be supported at one of the shaft doors for evacuation, there are several advantages.
  • the cabin apron is characterized by a high level of stability. Thanks to the support, it is ensured that the floor-side effect on the car apron, for example if the person presses against the apron as a result of a fall during an evacuation of people from the car, can simply prevent undesired yielding into the shaft interior.
  • the arrangement makes it possible in a reliable manner that even strict standard requirements can be easily met. Complex and costly structural measures for the stable and rigid attachment of the cabin apron to the cabin can be dispensed with. In particular, it is not necessary to provide additional or special locking means to secure the barrier division of the cabin apron.
  • the cabin apron In the rest position, the cabin apron can be positioned in a substantially horizontal position below the cabin, close to a cabin underside;
  • the car apron to block the gap between the car and the floor can preferably be directed in a vertical position downwards towards the shaft pit, the car apron preferably running parallel to the shaft wall on the shaft door side.
  • the rest position corresponds to a position for normal operation, in which position the cabin apron is positioned close to a cabin underside. In this rest position, there would be a gap between the car and the floor if the car were to get stuck between the floors. For safe evacuation of the trapped This gap must be closed for people from the cabin. To do this, the cabin apron is moved down into the barrier division.
  • the barrier division is the position for closing the gap between the floor and the underside of the car and thus preventing people from falling from the floor into the elevator shaft via an open shaft door.
  • Two guide rails for guiding the car can be provided in the elevator shaft.
  • the guide rails can preferably be arranged opposite one another on ent speaking shaft walls of the elevator shaft.
  • the cabin can also have a cabin door.
  • the cabin can have a front side, a rear side opposite the front side and parallel cabin sides connecting the front and rear sides.
  • the cabin door and thus also the cabin apron are arranged in the area of the front.
  • Guide rails for guiding the car can be attached to shaft walls which are adjacent to the aforementioned two parallel car sides.
  • the guide rails can be positioned in the shaft in such a way that, in a plan view, they are approximately in the center of these cabin sides.
  • Controllable or manually operable securing means can be provided on the cabin, with the aid of which the cabin apron is held securely in the horizontal position close to the cabin underside in the rest position on the cabin.
  • the cabin apron can also be designed in such a way that, after it has been released or released by appropriate control or operation of the securing means, the cabin apron can be transferred to the blocking position.
  • the cabin apron can preferably be designed to be movable about a horizontal pivot axis.
  • the car apron can also have a downwardly protruding blocking segment to block the gap between the floor and the underside of the car and a support segment that adjoins the blocking segment at the pivot axis and protrudes upward in the blocking division to secure the vertical position of the cabin apron.
  • the support segment is the element of the cabin apron which, when exposed to horizontal forces from the outside, for example through the The cabin interior supports people alighting at the shaft doors during an evacuation. When the force is exerted, the free upper end of the support segment abuts the respective shaft door and thus prevents the undesired further backward pivoting movement.
  • the cabin apron can be a flat apron element, the flat apron element comprising the aforementioned locking segment and the support segment adjoining it and preferably lying on the same plane.
  • the support segment forms a stop to prevent the car apron from pivoting back in the direction of the underside of the car under the action of horizon tal forces from the outside by people getting out of the car interior.
  • the support segment forms a protruding part of the cabin apron.
  • the support segment has a length of at least 10 cm. The length he mentioned is measured starting from the pivot axis to the free end or to the upper edge of the cabin apron.
  • the cabin apron is mounted on the cabin such that it can be pivoted and displaced via a guide track. Thanks to the swiveling and sliding movement, it is easy to move the car apron from the rest position, in which the car apron is positioned below the car in a horizontal position close to the underside of the car, and to the barrier division, in which the car apron is parallel to the shaft door-side wall in a vertical position runs and close to the landing door.
  • the guideway can be formed, for example, by a groove or a rail.
  • the cabin preferably has two mutually opposite guide grooves or guide rails, the guide grooves or guide rails being arranged in the region of the cabin floor on the opposite parallel cabin sides.
  • the guide track can have a guide section. With the help of the guide section, the car apron can be easily moved and the horizontal distance to the shaft door can be easily bridged.
  • the guide section can be linear or have a curved course.
  • the guide track can have an inclined, preferably linear guide section.
  • the inclined guide section is inclined relative to the Horizon tal.
  • the inclined course ensures that the car apron can be moved into the barrier division due to the force of gravity. After releasing or releasing by appropriate control or operation of the securing means, the cabin apron can automatically be brought into the barrier division under the action of gravity.
  • the guide track can have a vertically extending end section adjoining the guide section.
  • the end section ensures that the cabin apron cannot easily be pushed back by applying a horizontal force.
  • the apron To restore the initial position, the apron must first be lifted, i.e. moved slightly upwards in a vertical direction until a curve point is reached from which the apron can be moved further backwards around the guide section, with the apron moving backwards during or after the second-mentioned sliding movement is pivoted up.
  • the end section which is preferably short in comparison, can have a linear or curved course.
  • the end section can have a front end for specifying the locking pitch.
  • This front end corresponds to an end point of the guideway.
  • the front end forms a lowermost point of the guideway, so that the pivot axis of the cabin apron is temporarily fixed.
  • the front end of the end section is positioned in such a way that in the barrier division the vertical car apron runs close to and almost parallel to the shaft door.
  • Temporarily fixed here means that the cabin apron can only be swiveled when horizontal forces are exerted.
  • the front end of the end section is preferably arranged so close to the shaft wall on the shaft door side, the pivoting movement is essentially prevented or only a slight pivoting movement is possible, since the shaft door abuts the shaft door.
  • the car apron can have a pair of articulated cams for specifying the pivot axis have which engage in a pair of parallel guide grooves on the cabin which form the guide tracks.
  • the car apron can be a continuous axle shaft for specifying the pivot axis, which engages in guide grooves on the car.
  • the cabin apron can have a central, preferably approximately rectangular cutout in the region of the support segment.
  • Such a design can help that the support segment has a sufficient length, but, thanks to the cutout, there is no disruptive obstacle at the door sill. In this way, even with extra-long support segments, it is ensured that the car opening is completely free when the car doors are open.
  • FIG. 1 shows a greatly simplified representation of an elevator system according to the invention with a car which can be moved up and down in an elevator shaft and which is equipped with a movable car apron, the car apron being in a rest position.
  • FIG. 3 shows an enlarged representation of a car apron for the elevator system according to the invention
  • FIG. 4 shows a variant of the cabin apron according to FIG. 3,
  • FIG. 5 shows a front view of a cabin with a cabin apron in a barrier division according to an exemplary embodiment.
