Definitions

  • the invention relates to an elevator according to the preamble of claim 1.
  • the elevators used in buildings include a car, a counterweight, guides for the car and the counterweight, a cable arrangement, a drive, a braking device and a controller.
  • a machine room for the drive, the braking device and the control requires space that is not available in all buildings. This is why the drive and the braking device are arranged in the lift shaft, especially in tight spaces.
  • the control is arranged in such a way that it is accessible from the area of the building that can be used by people.
  • EP 1 562 849 B1 and US 2012/0305337 A1 describe solutions in which the control is arranged in a door post, that is, in a vertical frame part of an access door.
  • special door posts are used which essentially have a horizontally parallel displaceable area or an area which can be tilted about a horizontal axis over their entire height.
  • Such special door posts are different from all other door posts used for the elevator and their manufacture and assembly is associated with a great deal of effort. It is easy to see that a visible surface of these door posts can be moved away from the door post essentially over the entire height of the door post, which leads to an undesirable appearance.
  • US 7 434 664 B2 and US 2012/0080273 A1 describe the evacuation of people who are in an elevator car between two stations in the event of a breakdown in operation.
  • the brake is released with an evacuation control so that the elevator car is due to a weight difference between the weight of the elevator car can move with passengers and the counterweight to the next door.
  • the evacuation control or a cabinet with this must be located near the elevator and are perceived there, which can lead to misuse and negatively affect the appearance.
  • EP 1 148 018 B1 describes a cabinet arranged next to an access door of the elevator with a maintenance control panel which, independently of the electrical supply, can release the elevator brake and move the elevator car to a door.
  • a monitor on the maintenance control panel enables the speed to be limited by releasing the brakes as soon as a maximum permissible speed is reached.
  • the arrival of the elevator car at a door is visually checked via an inspection opening.
  • the cabinet with the maintenance control panel disturbs the appearance, takes up space and requires a specific mounting arrangement.
  • WO 2008/072023 A1 describes a solution in which the control, the power supply and the drive are arranged in the lift shaft. Control and display parts for emergencies and inspections are arranged in a mobile auxiliary device. A switchover and connection device is arranged next to an access door of the elevator, so that in the event of emergencies and maintenance it is possible to switch from normal operational control to control via the mobile auxiliary device. The switchover and connection device disturbs the appearance, takes up space and requires a specific mounting arrangement.
  • JP H10 95580 A shows a generic elevator with a device arranged at the control panel, with which a brake can be released for an emergency evacuation.
  • the invention is now based on the object of finding a solution in which the emergency evacuation can be ensured with little construction and assembly effort, without disruptive elements.
  • the emergency evacuation may only be carried out by specially trained persons. In the context of the invention, it was recognized that only these people should know the access to operate the emergency evacuation. People who only use the elevator should not give any indications that the emergency evacuation is being operated obtain. All elevator stations should only have the elements necessary for regular elevator use on a standard control panel.
  • the standard control panel includes at least one outside handle with which the elevator can be ordered. If necessary, there are separate outside handles and a travel and / or position display for both directions of travel.
  • the control panel is arranged on an opening of a door frame or a vertical frame profile that corresponds to the standard control panel.
  • the opening in the door frame for the control panel is preferably a maximum of 30 cm high and a maximum of 10 cm wide, so that the mechanical stability of the door frame is only insignificantly reduced by the opening and the processing effort for creating the opening is as small as possible.
  • a device which enables emergency evacuation is arranged on the inside of the door frame facing away from the operating side of the operating panel.
  • the device for carrying out the emergency evacuation is located behind the standard control panel and can be operated from the outside of the door frame after at least partial removal of the control panel.
  • the opening can be operated manually or via control connections such as cables or control devices.
  • All access doors or their door frames with the respective control panel can look the same.
  • the same door frames with a standard opening for the control panel can be used for all doors. For this reason, when producing the frame profiles and the door frames and when assembling the door frames, it is not necessary to pay attention to whether it is a door with a facility for emergency evacuation. The decision as to whether a facility for emergency evacuation will be placed next to a door can be made after the standard door frame has been installed.
  • standard control panels are used which can be releasably fastened to the opening of the door frame with a type of fastening known from the prior art, in particular with snap-in elements and / or with releasable connecting elements. After detaching a control panel, it can hang on the cables to the control panel under the opening in the door frame be left.
