Definitions

  • the invention relates to a pneumatic or hydraulic drive for opening and closing doors, in which the linear movement of a double-acting piston driven by a pressure medium is converted into a rotary movement of a spindle via a piston rod and a screw gear.
  • the invention aims to provide a device that blocks the opening movement of the door when the pressure drops. According to the invention this is achieved in that a stationary locking lever is provided, which acts under the action of a spring in the closed position of the door on a part connected to the piston, whereby it secures the calves in its end position and counteracts it by means of a working cylinder acted upon by the pressure medium Is held in its open position by another spring.
  • the locking lever is connected to a manually operable Bowden cable.
  • a particularly advantageous embodiment results when the Bowden cable starts from a hand lever with which a three-way valve can be actuated in the pressure line of the pressure medium, which connects the pressure medium line to the return flow in one end position of the hand lever. This creates an emergency actuation.
  • the subject matter of the invention is shown in an exemplary embodiment.
  • FIG. 1 shows a view of a door drive according to the invention in elevation
  • FIGS. 2 and 3 show a cross section
  • the locking lever being shown in its effective position and in FIG. 3 in its inactive position
  • FIG. 4 a control circuit .
  • a shaft 2 is mounted in a bracket 1 and can be rotated by means of a screw gear 3.
  • a working cylinder 4- with a double-acting piston 5 including inflows and outflows for the pressure medium is provided below the screw gear.
  • the piston rod 6 is provided with a pair of rollers 7, which is guided in slots 8 of the screw gear 3.
  • an angular locking lever 10 is pivotally mounted on a bracket 9, which engages under a roller 11 in its locking position, not shown, which is mounted 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.
  • a compression spring 15 is inserted between one end face of the working cylinder 14 and the piston 13.
  • the working cylinder 14 is pivotally mounted on a bracket 16.
  • the locking lever 10 is fixedly connected by means of a shaft to a lever 10a, to which a Bowden cable 17 engages, which enables the locking lever 10 to be pivoted out of its locked position against the force of a torsion spring 18 by hand.
  • the entire device is covered by a pot 19.
  • the working cylinder 4 is connected by means of the lines 20, 21 to a control valve 22 which, on the one hand, is connected to a pressure source 23.
  • Another line 24 leads back into the medium reservoir.
  • a branch line 25 leads from the pressure line to the working cylinder 14.
  • a valve 26 is connected in the pressure line, which can be actuated by means of a hand lever 27. It optionally connects the pressure source 23 to the valve 22 or the pressure line to the reflux.
  • One end 28 of the Bowden cable 17 is fastened to the hand lever 27.
  • 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 on the lines that are under pressure and the pressure therefore drops, the first step is under the influence of the spring 15, the piston 13 is pressed into the working cylinder 4, which initially compensates for the amount of leakage.
  • the locking lever 10 was brought into its locking position by the piston rod 12, in which it engages under the roller 11
  • the hand lever 27 is actuated, whereby the pressure line is connected to the return line 24 through the valve 26 and the Bowden cable is actuated at the same time, 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. It does not matter which section of the pressure line 20 the branch line 25 starts from.

Abstract

Dispositif d'entraînement pneumatique ou hydraulique pour l'ouverture et la fermeture des portes, dans lequel le mouvement rectiligne d'un piston (5) à double effet actionné par un milieu sous pression est transformé en un mouvement rotatif d'un arbre (2) par l'intermédiaire d'une tige de piston (6) et d'un organe à mouvement hélicoïdal (3). Un levier (10) de blocage monté pivotant en un endroit fixe agit, sous l'effet d'un ressort (18) en position fermée de la porte, sur une pièce (11) reliée au piston (5), assujettit le piston en fin de course et est maintenu dans sa position d'ouverture à l'encontre de la force d'un autre ressort (15) à l'aide d'un vérin hydraulique (14) actionné par un milieu sous pression.
