Definitions

  • the invention relates to a door operating device according to the preamble of the main claim.
  • a door operating device is known - Bosch publication VDT-AKB 130/2, sheet 1 (2.67).
  • the door actuation device with the characterizing features of the main claim has the advantage that the normal actuation by the driver in the closing and opening direction is combined with an emergency actuation, which depressurizes the closing line.
  • the emergency operation also allows the passenger to open and close the door by hand, but the emergency valve cannot be moved back to its original position because it is locked until the driver puts the door valve in the open position. Then the pressure in the working cylinder is first built up on both sides, and the locking of the emergency valve is only released when a certain pressure is reached so that the door does not close abruptly. It is thereby achieved that, starting from each position of the working cylinder and in every direction, end position damping of the working cylinder is effective.
  • FIG. 1 shows the door closed, the door valve in the closed position, the electrical system has failed, the emergency control in the initial position
  • FIG. 2 shows the emergency control in the changeover position
  • the closing and opening sides are vented
  • the door is pushed open by hand, the emergency control is locked
  • FIG "Open" electrical system is intact
  • door valve in the "open” position both chambers of the working cylinder are ventilated at the same time and Figure 4 locking is released automatically, emergency control returns to the starting position, the door goes into the "open” position.
  • a door 1 is connected via a piston rod 2 to a double-acting piston 3 of a two-chamber working cylinder 4.
  • the two chambers 5 and 6 of the working cylinder 4 are connected via connections to an air line 7 or 8, of which the line 7 starting from the opening side x of the working cylinder 4 leads directly to a door valve 9, which as a 3/2-way Solenoid valve is formed and to which a reservoir 20 is connected as a pressure source.
  • the other line 8 starting from the closing side y of the working cylinder 4 leads to an emergency control 10 and there to a multi-way valve designed as a 3/2-way valve 11 which can be operated by hand.
  • the valve 11 can be actuated either by a toggle or a rotary knob, the actuation preferably being to operate in such a way that it can only transmit force in one direction.
  • a rotary slide valve which is provided with a torsion spring, has proven itself as a 3/2-way valve 11.
  • the torsion spring When actuated, the torsion spring is tensioned, and at the end of the rotation, a radial lock 12 ( Figures 2 and 3) is reached, and this lock can be released pneumatically via a working member 13, after which the pneumatic pressure also returns the 3/2-way valve 11 supported in its starting position.
  • a radial lock 12 Figures 2 and 3
  • a throttle 14 is connected upstream of the working member 13.
  • the throttle 14 can also be replaced by a spring 14 'on the working member 13.
  • Working member 13 and throttle 14 are in a branch line 15, which has connection to the air line 7, which is connected on the one hand to the opening side x of the working cylinder 4 and with the door valve 9 and on the other hand connected via a line 16 to a third connection of the valve 11 is.
  • FIGS 1 to 4 show the door operating device in different positions. The same reference numbers are therefore used for the same parts.
  • the door valve 9 has such a position that the door 1 is closed. It is now assumed that the magnet adjusting the door valve 9 receives no current, then can do not switch the door valve 9 and the passengers cannot get out.
  • FIG. 2 shows the state of the door operating device when the emergency control 10 has been operated by someone.
  • the manually operated 3/2 valve 11 then assumes its other position, in which the closing side y of the working cylinder 4 is now also vented, specifically via the 3/2 valve 11, the lines 16 and 7 and the door valve 9
  • the door 1 with the double-acting piston 3 in the working cylinder 4 can be moved into the open position without resistance. The passengers can get out.
  • FIG. 3 shows that when the 3/2 valve 11 is locked, the door can be open in any position between “closed and”.
  • the valve 11 is in the short-circuit position. This fulfills the requirement that actuation of the emergency control does not result in pressure-induced movement of the door.
  • the power supply to the magnet of the door valve 9 is intact again; therefore the door valve 9 can be switched to the «open» position. As a result, the two working chambers 5 and 6 of the working cylinder 4 are evenly ventilated. Door 1 remains as it was.
  • FIG. 4 it can now be seen that the locking on the working member 13 has been released by the pressure increase delayed, for example, via the throttle 14, and the 3/2 valve 11 of the emergency control 10 has returned to its starting position.
  • the closing side y of the working cylinder 4 is vented and the door 1 goes into the open position.
  • the emergency control 10 only returns to its starting position if the door valve 9 had previously assumed its open position. This ensures that the end position damping in the working cylinder is effective starting from every position of the working cylinder and in every direction.
  • actuation of the emergency control cannot bring about a closing of the door and no locking of the emergency actuation, because the working member 13 of the lock 12 is under pressure (position according to FIG. 4).
  • the door valve 9 To close the door 1, the door valve 9 must first be brought into the position shown in FIG. 1.

Claims (2)

1. Dispositif de commande de porte comprenant un cylindre de travail à deux chambres, qui est destiné à actionner la porte (1) et dont le piston (3) est relié à la porte par une tige de piston, une soupape de porte (9) commandée électromagnétiquement et par l'intermédiaire de laquelle chaque chambre (5, 6) du cylindre de travail (4) peut normalement être reliée alternativement à une source de pression ou à un emplacement d'échappement, et une commande de secours (10) pouvant être actionnée à la main, caractérisé en ce que la commande de secours (10) comprend une soupape à plusieurs voies (11) qui est disposée sur une conduite de fermeture (8) du dispositif pour la commande de secours manuelle de la porte, qui présente en position de repos (figures 1 et 4) un passage pour le milieu sous pression admis dans ou sortant de la soupape de porte (9) qui, après inversion (figures 2 et 3), relie l'une à l'autre les deux chambres (5 et 6) du cylindre de travail (4) en vue d'une mise commune sous pression ou hors pression et qui, dans cette position, peut être verrouillée mécaniquement et déverrouillée pneumatiquement pour revenir dans sa position de départ, de sorte qu'un verrouillage (12) de la soupape à plusieurs voies (11) ne peut cesser automatiquement que lorsque est déclenchée par la soupape de porte (9) une montée en pression provoquant l'ouverture de la porte.
