Definitions

  • the invention relates to an elevator, in particular inclined elevator, with two mutually parallel, fixed roadway profiles, in particular roadway tubes, on each of which guide rollers run, which are rotatably mounted on roller carriers and bear against the roadway profiles from different sides.
  • the carriageway profiles serve exclusively as guide profiles on which associated guide rollers run.
  • the elevator is driven with additional drive elements.
  • a pull rope is provided which runs endlessly in the guide tubes and in which the connection between the pull rope and the load-carrying means takes place via a slot in the upper guide tube. It is also known to carry out the drive via racks which extend parallel to the roadway profiles and on which a gear wheel runs.
  • overhead conveyors are also already known, in which only a single carriageway tube is provided, on which a drive device runs, to which the load suspension device is attached with a bracket as in a chair lift (EU 0 088 061 A2).
  • the driving force of the drive wheel is transmitted essentially non-positively to the roadway profile.
  • Such constructions developed from overhead conveyor conveyors have the serious disadvantage that they have no reliable guidance for the load suspension means. In most cases, they are therefore not permitted as personal lifts, in particular as handicapped lifts.
  • the invention is based on this prior art based on the object of designing an elevator of the type assumed to be known in such a way that it can be manufactured inexpensively and nevertheless function perfectly with simple means.
  • the elevator according to the invention has the advantage that the load suspension means is guided in any desired direction and change of direction.
  • the elevator according to the invention can run safely on both straight and curved lane profiles.
  • the roadway profiles can be arranged both horizontally and vertically, both ascending and descending.
  • the roadway profiles can also be curved in a top view and form tight curves, as is necessary, for example, for use in stairwells.
  • the construction according to the invention allows any desired travel.
  • the driving force prefferably be generated by means of a guided compression spring.
  • a guided compression spring means that even in the event of a spring break, the remaining spring forces maintain a sufficient contact pressure of the drive wheels on the guide profiles.
  • the guided compression spring is tensioned between the two roller carriers pivotably mounted about horizontal axes and acts at a distance from their pivot axes. Further preferred embodiments of the invention are described in the further subclaims.
  • FIG. 1 - a schematic side view with the essential parts of an elevator in different travel positions
  • FIG. 2 - an enlarged side view of the upper drive area

  • FIG. 4 - a representation of a second embodiment analogous to FIG. 1,
  • FIG. 5a shows a representation of the second embodiment analogous to FIG. 2,
  • FIG. 5b shows a view of the upper drive area according to FIG. 5a in the direction of arrow Vb
  • FIGS. 1 and 4 shows a representation of a third embodiment which is analogous to FIGS. 1 and 4 and is designed as a chair system
  • FIG. 7 - a side view of the chair system in an enlarged view
  • FIG. 8 - an end view according to arrow VIII in FIG. 7,
  • FIG. 9 shows a side view of a vertical elevator, only partially shown
  • FIG. 10 shows a plan view of the drive unit of the vertical elevator in the direction of the arrow X in FIG. 9,
  • FIG. 11 shows a side view of a further embodiment of a vertical elevator

Abstract

Un ascenseur, en particulier un ascenseur incliné, possède deux profilés de guide-rail fixes et parallèles, sur lesquels roulent respectivement deux patins de guidage rotatifs maintenus par des supports de patin et venant s'appliquer sur différentes faces contre les profilés de guide-rail. A cet effet, au moins un patin de guidage est conçu sur chaque support de patin comme roue motrice. La circonférence de la roue motrice est pressée par la force d'un ressort sur la zone de contact commune du profilé de guide-rail de telle sorte que la force d'entraînement de la roue motrice est transmise au moins sensiblement par adhérence sur le profilé de guide-rail.
