Definitions

  • the invention relates to elevator systems for buildings with a car, which is connected to a drive mechanism via a traction means.
  • Known elevator systems essentially consist on the one hand of an elevator shaft with guide rails, shaft doors, a cabin including safety gear and magnetic switch, a counterweight and information-providing devices and on the other hand of a machine room of the machine as electric motors or hydraulic drives, a speed limiter, a control and a main switch. Solutions of this type are found, inter alia, in the publications EP 0 955 262 A1 (hydraulic elevator), EP 0 957 060 A1 (hydraulic rope elevator), DE 198 51 726 A1 (elevator with a spindle lifting rope drive), DE 199 02 853 A1 (passenger rope elevator), DE 298 14 744 U1 (elevator with drive) and DE 298 19 566 U1 (elevator).
  • Walls of the lower region of the shaft are arranged at an angle to one another, the cross section tapering in the direction of the lower end of the shaft.
  • the air is directed to the outside via pipes attached to the side and led upwards and via several valves into an intermediate space in the floor of the cabin and subsequently into the interior of the cabin. If the valves fail, the function is no longer guaranteed.
  • the drives are connected to the cars. Solutions of this type are listed, inter alia, in EP 0 614 843 A1 (drive device for a self-propelled elevator car) and DE 198 34 994 A1 (elevator system with integrated machine unit). No counterweights and traction devices are used in these elevator systems. However, guide rails and cabin frames are also required.
  • the invention specified in claim 1 is based on the task of creating an easy-to-implement elevator for buildings, which is further characterized in that it can be easily installed or installed both under construction and in existing buildings. This object is achieved with the features listed in claim 1.
  • An embodiment of the tubular body in a self-supporting and supporting and / or supporting construction with a closed inner wall ensures a separate design of the elevator system which is independent of the building.
  • the elevator system can easily be placed both inside and outside a building.
  • Another advantage is that the elevator systems can also be installed in existing buildings without affecting the statics of this building.
  • the tubular body is dimensioned so that it absorbs all horizontal and vertical forces resulting from the operation of the elevator.
  • the tubular body represents an assembly that is largely independent of other on-site trades. The realization of the tubular body, in particular from several parts, ensures easier assembly, preferably also in existing buildings.
  • At least one opening either between the cover plate of the cabin and the inner wall of the tubular body or the cover plate of the cabin according to the further development of claim 3 ensures the air balance between the interior of the cabin and the volume of the tubular body above it during a movement or when the cabin is stationary in the tubular body.
  • the opening must be large enough to ensure that there is sufficient air exchange when the cabin is occupied.
  • Air exchange means compression and suction during the movements of the cabin.
  • cross sections of the tubular body and the base plate of the cabin are either polygonal or the shape of a conical section, in particular in the form of a circle, or an ellipse.
  • the element in particular a seal between the base plate of the cabin and the inner wall of the tubular body according to the further development of claim 6, secures a compressible air cushion for braking the movement of the cabin in the event of an unwanted draining or tearing of the traction means.
  • the controllable valve which connects the free space between the end of the tubular body and the lowest opening with the environment, after the training of claim 7 ensures a normal air balance during normal downward or upward travel of the cabin, so that the movement-preventing compressions or suction are largely avoided. This allows the cab to move freely.
  • An electrical synchronous motor or servo drive as a drive mechanism for the cabin in the tubular body according to the development of claim 8 is characterized by freedom from maintenance and favorable heat development. Such drive mechanisms can be controlled so that large transmissible torques can be achieved even at low speeds. This provides a direct drive for the movement of the cabin in the tubular body. Conventionally necessary counterweights, including their structural requirements, are not necessary.
  • Sliding bodies and / or rolling elements on the one hand on the cabin and on the other hand between the cabin and the inner wall of the tubular body according to the development of claim 9 improve the guidance of the cabin in the tubular body. Tilting movements of the cabin, especially when moving off, are largely excluded, so that safe operation is ensured.
  • the lockable cabin door according to the development of claim 10 leads to defined aerodynamic relationships between the cabin and the tubular body, since largely constant volumes are guaranteed. Furthermore, the safety for the users during the movement of the cabin in the tubular body is increased.
  • the automatic function of the elevator system according to the invention can be guaranteed via a control and / or regulating device, in particular a computer and the associated assemblies in the form of the control of the drive mechanism, the rotary encoder and the device for position measurement.
  • the controllable valve can also be connected to it be, so that the associated advantages are guaranteed.
  • the free space 6 between the end 5 of the tubular body 1 and the lowermost opening 11 can be connected to the environment via a controllable valve.
  • the control of the valve is connected to a computer. This ensures that during a normal upward and downward movement there is no suction or compression in the interior of the tubular body 1.
  • the valve is only closed as quickly as possible when the car 2 is inadvertently moved downward by a malfunction during the movement of the car 2 of the elevator system, so that the amount of air present under the car 2 can be compressed.
  • 16 position securing elements can be present at the individual stops on the floors. These are positive or non-positive connection elements which releasably engage the inner wall of the tubular body 1 and are attached to the base plate 7 and / or the cover plate 8 of the cabin 2. The controls of the actuating elements of the position securing elements are connected to the computer.

  1. Appareil élévateur pour bâtiments avec une cabine qui, au moyen d'un mécanisme de traction, est raccordé à un mécanisme d'entraînement, la cabine étant montée sous forme mobile et verticalement disposée dans un corps tubulaire qui, lui aussi, est verticalement disposé et monté de façon mobile.
