Definitions

  • DE-A-31 12 646 discloses a door drive in which this fuse is provided within the working cylinder in direct cooperation with the piston. These designs require a support column that can be raised and lowered.
  • this is achieved in that the locking lever engages under the action of a further spring in the closed position of the door on a part connected directly to the piston rod from the drive cylinder to the outside, the movement of which is derived from the axial movement of the piston, and the piston secures in its closed end position.
  • an angular locking helix 10 is pivotally mounted on a bracket 9, which engages under a roller 11 in its locking position, not shown, which is supported coaxially with the pair of rollers 7 on the piston rod 6.
  • a piston rod 12 of a piston 13 is articulated on the locking lever 10 slides in a working cylinder 14 and is pressurized on one side with the same pressure medium as the double piston 5.
  • the working cylinder 4 can be set to open or close by means of the valve 22.
  • the double-acting piston 5 In the closed position, the double-acting piston 5 is in its upper end position and is held in this position by the pressure medium.
  • the working cylinder 14 is always connected to the pressure line, so that the piston 13 is in its end position compressing the spring 15, in which it holds the locking lever 10 out of its locked position.
  • the hand lever 27, which represents an emergency device with the Bowden cable 17 and the valve 26, is in the position in which the valve 26 connects the pressure source 23 to the valve 22. If there is a leak at any point in the lines that are under pressure and the pressure therefore drops, the first step is under the influence of the spring 15 of the piston 13 pressed into the working cylinder 4, whereby the leakage amount is initially compensated.
  • the locking lever 10 was brought into its locked position by the piston rod 12, in which it engages under the roller 11 (FIG. 2). If pressure medium escapes further, the working piston 4 is depressurized. However, the door cannot be opened by itself or under load. However, opening the door is temporarily possible if the Bowden cable 17 is actuated by means of the hand lever 27. When the lever 27 is released, the locking lever 10 returns to its locking position.
  • the hand lever 27 is actuated, whereby the pressure line connects the pressure line to the return line 24 and at the same time the Bowden cable is actuated, so that the locking lever 10 is held in its open position, although not only the working cylinder 4 but also the working cylinder 14 are depressurized.

Claims (1)

1. Dispositif d'entrainement pneumatique ou hydraulique pour l'ouverture et la fermeture de portes, dans le cas duquel le mouvement linéaire d'un piston (5) à double action, entrainé par un fluide sous pression, est converti, par l'intermédiaire d'une tige de piston (6) et d'un mécanisme à vis (7, 8), en un mouvement de rotation d'un arbre (2), dispositif dans lequel est prévu un levier de verrouillage (10) qui est monté en position fixe, qui est relié avec un câble coulissant sous gaine type Bowden (17) manoeuvrable à la main, qui, dans sa position de verrouillage, assure la position de fermeture de la porte, qui est maintenu dans sa position de non-verrouillage, à l'encontre de la force d'un ressort (15), au moyen d'un vérin (14) contraint par le fluide sous pression indépendamment du vérin d'entrainement et qui, en cas de chute de pression dans le vérin d'entrainement, revient dans sa position de verrouillage, dispositif caractérisé par le fait que, sous l'action d'un autre ressort (18), le levier de verrouillage (10), en position de fermeture de la porte, agit sur une pièce (11) qui est directement reliée à la tige de piston (6), qui est guidée vers l'extérieur depuis le cylindre d'entrainement (4) et dont le mouvement dérive du mouvement axial du piston (5), et assure le piston dans sa position extrême de fermeture de la porte.
