Definitions

  • the present invention relates to a folding door system.
  • the invention relates to a folding door system with an adapted center seal profile.
  • Folding door systems are known from the prior art, which have seals on the closing edge.

  • a folding door has a special kinematics during the closing process. Thus, during closing, each folding wing door is first pressed a few millimeters beyond the actual closing point, and then returned to the fully closed position. The sealing contour or the sealing lip is compressed so much that the engine system outputs an error message or an excessively strong force acts on the drive train. This leads in the long term to malfunction or malfunction.

It can be seen here that the folding-wing doors 2, 3 rest directly on the sensor field 59, in particular on the projection 58 of the sensor field 59 of the obstacle sensor 57. Thus, the projection 58 has a first entrance area 63 into which the first folding door 2 enters during an opening operation or a closing operation, while the second folding door 3 enters a second entrance area 64 of the projection 58. However, this would always lead to the erroneous assumption that an obstacle is located within the closing path of the folding doors 2, 3. To prevent this, the monitoring device 23 is installed, which in Fig. 16 or 17 execute flowcharts shown. In the Fig. 16 and 17 are shown below with reference to the Fig. 13 to 15 explained.

Since the first folding door 2 and the second folding door 3 are located within the activation area 62, detection of the first wing 24 or the second wing 25 of the first folding door 2 or the second folding door 3 is within the projection 58 and thus false detection of a non-existent one Obstacle excluded. It must therefore be an external obstacle with a detected obstacle, for example, a desire of the folding door system 1. Thus, the stopping and / or reversing is necessary. Subsequently, the final termination step S05 is executed.
  • the obstacle sensor 57 is permanently activated, with signals from the obstacle sensor not being used at all times.

If this is not the case, then in a third step S13 the obstacle sensor 57 is deactivated and the first step S11 is continued.
  • the folding door system 1 is in a position in which the signal of the obstacle sensor 57 is not reliable, since in this position an erroneous detection of the first folding door 2 or the second folding door 3 is possible as an obstacle.

  • the folding door system 1 is in the closed position. If it should now be detected by means of the position sensor that the folding wing doors 2, 3 are not in the closed position, this must have been caused by a gust of wind. Alternatively, this can also be done by a manually applied force on the folding door system 1. In both cases, however, is undesirable that the folding doors 2, 3 open.
  • the wind load control is implemented such that it tries to minimize a deviation of the door position of the folding doors 2, 3 from the target position, that is, from the closed position.

With such a resolution it is ensured that the positions of the first folding door 2 and the second folding door 3 are reliably detectable.
  • the drive unit 4 With the increased current, the drive unit 4 generates an increased closing force acting on the first folding door 2 and on the second folding door 3.
  • This closing force causes on the one hand a locking force when the folding door unit 1 is in the fully closed position, on the other hand, the closing force causes a closing of gusts open wings 24, 25 of the folding door system 1.
  • a time counter is started, the in particular 15 minutes.
  • the first rule complex which is initiated by the first step S21, ensures that in repeated gusts no repeated opening of the folding door system 1 takes place.
  • the starting of the counter in the third step S23 allows a gradual reduction of the current increased in the second step S22. This reduction is the subject of the second rule complex, which is initiated with the fourth step S24.
  • the fourth step S24 determines whether the time counter has been started. If this is the case, the fifth step S25 is executed at regular intervals. The regular intervals are in particular every three minutes. Finally, in the fifth step S25, the current increased in the second step S22 is lowered, in particular by 100 mA each time. Subsequently, the process proceeds to the sixth step S26. This is preferably repeated five times, so that after 15 minutes, the time counter is running, the increased current is lowered five times by 100 mA. After the 15 minutes, the current increased in the second step S22 is thus completely reduced again. In this way, an overload of the drive unit 4 is avoided in particular.
  • the third rule complex is initiated with the sixth step S26.
  • the sixth step S26 it is determined whether the folding doors 2, 3 have a deviation from the fully closed position. Such a deviation is, as already described above, generated in particular by a wind load or by a manual force on the wings 24, 25 of the folding door system 1. Since the folding door unit 1 should remain in the fully closed position, such a deviation is undesirable.
  • the seventh step S27 is continued.
  • the current that is output to the drive unit 4 is increased.
  • the increase is in particular linear to the deflection of the folding doors 2, 3 from the fully closed position.
  • a p-controller is implemented.
  • the output current exceeds a predetermined maximum rated current. This is checked in an eighth step S28. If the maximum rated current is exceeded, then the ninth step S29 is continued. If, on the other hand, there is no overshoot, the process is ended with the termination step S30.
  • the current applied in the seventh step S27 is lowered to the drive unit up to the maximum rated current. This is done in particular within a predetermined period, which is advantageously ten seconds.
  • the short overload of the drive unit ensures that the folding door unit 1 remains in the closed position even in the case of strong gusts of wind.
  • a delicate folding door system 1 can be realized, which nevertheless has a sufficiently high-performance wind load control, so that the folding door unit 1 remains in the closed position even in the presence of strong gusts of wind.
  • the Fig. 19 shows finally traversing curves of the folding door 1 during an opening and closing of the folding doors 2, 3.
  • the upper diagram shows a speed profile, while the lower diagram represents a profile of the acceleration.
  • a position of the folding doors 2, 3 is shown on the abscissa axis, that is, a position of the movable end 38 on the running rail 8. This means that at a left limit the folding door system 1 is completely closed, while the folding door 1 at a right limit on the abscissa axis is fully opened.
  • the coordinate axes of the diagrams show a velocity in the upper diagram and an acceleration of the folding-wing doors 2, 3 in the lower diagram.
  • the folding doors 2, 3 behave according to the upper curve of the diagrams. If the folding door system 1 is closed, however, the folding doors 2, 3 behave in accordance with the lower curves of the diagrams.
  • the illustrated profiles of speed and acceleration allow rapid opening of the folding door, while avoiding both opening and closing vibrations within the folding door system 1. Due to the reduction of the vibrations lowering of the wings 24, 25 of the folding door system 1 is minimized, so they can have a small distance to a floor. Thus, a thermal insulation is increased. At the same time allow the reduction of vibrations and the resulting minimum lowering of the folding doors 2, 3 to realize a large opening width. In particular, a maximum opening width of 2,400 millimeters is made possible in this way. This means that when using four wings 24, 25, as in FIG. 1 was shown, each wing has a width of 60 millimeters.
  • FIG. 19 It can be seen that the wings 24, 25 of the folding door system 1 from the drive unit to open the folding doors 2, 3 can be accelerated. In this case, after a travel of a maximum of one third, preferably of a maximum of a quarter, of the total travel path of the folding doors 2, 3 reached a maximum acceleration. So a quick opening of the folding door system 1 is realized. After reaching the maximum acceleration, the acceleration is lowered by the control unit 19, wherein the reduction is particularly linear. It is provided that the acceleration before reaching the last quarter, in particular before reaching the last third of the maximum travel of the folding doors 2, 3 is lowered to zero.
  • a maximum closing speed of the folding doors 2, 3 is at most half the maximum opening speed of the folding doors 2, 3.
  • a monitoring of the closing operation is possible, since the reduced speed when closing the folding door system 1 monitoring the closing movement allowed. Therefore, when detecting an obstacle within the travel path of the folding wing doors 2, 3, the folding door unit 1 can stop and / or reverse the wings 24, 25, which enables a very safe operation of the folding door unit 1.
