Definitions

  • the present invention relates to a device for balancing the weight of a door, a door construction having the device for a door, in particular for a garage door or industrial door, and a door having a door construction according to the invention.
  • the gates mentioned can comprise individual gate sections or sections, with the gates having at least one gate leaf.
  • the individual sections are guided laterally in rails, for example in the case of sectional doors, and can be moved from a vertical closed position into an open position.
  • Gates of this type can be used to close off different entrances or passages. This applies in particular to entrances to buildings in the private or commercial sector. Appropriate gates can be used, for example, to close loading ramp openings in a warehouse. Other areas of application are gates for industrial halls, warehouses, agricultural halls, single garages, double garages, collective garages. Other areas of application are also conceivable at this point.
  • Gate leaves or sections of a gate leaf according to the prior art consist, for example, of aluminum support profiles into which glazing or a panel can be inserted.
  • the girders form a shoring structure, which can then be provided with panels according to customer requirements.
  • the Aluminum profiles are thermally insulated.
  • the weight of the gate wing can be considerable depending on the equipment variant of the gate wing or the sections of the gate wing.
  • weight compensation arrangements in the form of tension or torsion springs are usually used, which are tensioned during a closing movement in which the gate leaf movement has to be slowed down, so that the energy stored in the springs is then available to support the opening movement.
  • the connection of the tension or torsion springs to the gate leaf is usually carried out via support means designed as a wire cable, which are coupled to the gate leaf or fastened thereto.
  • the gate leaves of sectional gates comprise a large number of gate leaf sections arranged one behind the other in the direction of movement of the gate leaf and articulated to one another via joints, in particular hinges, which have joint axes running perpendicular to the direction of movement. With these gates, the movement of the gate leaf is usually guided with the aid of guide rails.
  • Torsion springs can be used for the weight compensation device in such goals.
  • one end of the torsion spring is fixed in relation to the reveal of the opening to be closed with the gate leaf, while the other end of the torsion spring is coupled to a rotatably mounted torsion spring shaft.

  • the energy thus stored is then available to support the opening movement, as already described above.
  • the weight of the gate leaf can be several hundred kilograms in the case of gates, it is necessary to dimension the torsion spring and the supporting ropes on which the gate leaf hangs with appropriate tensile strength. This means that a larger rope diameter is required, which means that the wire ropes are less flexible or have larger deflection radii. What worsens the handling of the weight compensation device.
  • an approximately horizontally running section (overhead) of the guide rails is generally connected via an arcuate section to an approximately vertically running second section.
  • the sectional door can be brought from the closed position, with the sectional door being located in the vertically running second section, into an open position, in which the sectional door is located in the horizontally running first section.
  • the load on the weight compensation device changes gradually due to the weight of the sectional door.
  • the second roller and each additional roller transitions from the arcuate section to the vertical section.
  • the difference between the weight that has to be absorbed by the first and last roller is significantly lower than the weight that has to be absorbed by the rollers in between.
  • the WO 2013/140235 A1 relates to a mechanism particularly suitable for sectional door lifting systems.
  • the U.S. 2006/0096720 A1 describes a counterweight balancer having a cable drum support shaft and a torsion spring drive mechanism mounted adjacent one or two sides of the door and drivably connected to the drum support shaft.
