  • the damper 200 pivots out of the door when the door is opened, but the door closing function is generated by a cable 400 which is connected to one of the hinge levers 110 at one end portion and the tension springs 410, 420 at the other end ,
  • the cable 400 is connected to the hinge lever 110 in approximately the position in which in the embodiments according to the FIGS. 1 to 4 the pull rod 130 is hinged to the hinge lever 110.
  • FIG. 6a shows the arrangement with damper 200 and the FIGS. 6b and 6c without damper.
  • FIG. 7 shows the groove 302 of the carrier 300. From this figure it follows that the sliding elements 170 run in the groove 302. The support effect when closing is generated in the embodiment shown here via the roller 160. When opening, however, the upper groove side 303 forms the plant. Alternatively, it is conceivable to dispense with the roles and to take over the system not only when opening the door but also during the closing operation on the sliding elements 170 and via the groove 302.
  • the reference numeral 304 indicates the engaging engagement of the groove 302 via pure sliding friction.
  • FIG. 8 shows an enlarged view of the eccentric 100 and the compression spring arrangement, by means of which on the rollers 150 on the surface of the eccentric 100, a compressive force is exerted.
  • a change in the door closing characteristic can also be effected by influencing the eccentric track, ie the surface of the eccentric 100 in cooperation with a likewise changed cam track, as is known FIG. 9 evident.
  • reference numeral 100 ' denotes the cam track and reference numeral 150' the cam track.
  • FIG. 10 illustrates that by shifting the cylinder 202 of the damper 200 relative to the piston rod 204 and thus also relative to the piston, a significant change in the damping behavior can be effected.
  • This relative movement can, as is out FIG. 10 shows, either via a stepless adjustment of the cylinder 202, that is done the Dämpferanlenkung, as indicated by the double arrow shown on the left, or a piston rod side Relativlagever selectedung the Kolbenstangenanschung, as indicated by the double arrow shown on the right.
  • FIG. 11 finally clarifies that the Dämpferhubbegrenzung via the striking of the slider or 170 at the Nutende 302 'takes place.
  • spacers not shown here
  • the free groove length can be changed in a simple manner. In this way it is possible to produce a desired limited intermediate door opening position. It is also conceivable to produce this limitation of Gleitnemweges continuously via appropriate mechanisms, such as a pull rope.
  • FIG. 12 A further embodiment of the invention is in FIG. 12 indicated. Shown here is the damper lever 155, which, as stated above, the roller 160 and the slider 170 connects to the hinge lever 120.
  • damper lever 155 which, as stated above, the roller 160 and the slider 170 connects to the hinge lever 120.
  • These Damping characteristics based on the fact that the damper 200 never disengages over the entire door opening angle. This results in the advantage that unpleasant impact phenomena, which are neither desirable for the user nor for the material, are fundamentally avoided.
  • the damper lever 155 it is also conceivable for the damper lever 155 to be coupled into and out of the slide carrier 170 in a defined door opening angle range. As a result, a shortening of the required Dämpferweges can be achieved. To avoid possible shocks, this decoupled state should be in an opening area, which takes place anyway only with little attenuation.
