Definitions

  • the invention relates to a drive for a wing of a door, a window or the like with the features of the preamble of claim 1.
  • DE 27 51 859 describes a hydraulically operated door closer with a by a spring arrangement in the closing direction loaded closing shaft, which via a pinion with one in the hydraulic cylinder device of the door closer axially displaceable piston cooperates.
  • a possibly opened door wing is opened under the effect of the Door closer closed to prevent the fire from spreading.
  • an additional device is provided, which the normally open spring in a biased Holds position. If the closer spring is preloaded and blocked, the piston can be moved freely within the cylinder and thus also the door leaf manually can be operated freely.
  • the additional device has another, in the cylinder between the pressure chamber and pressure-free space arranged piston, which at the stop with the NO spring is.
  • the piston has a check valve opening towards the pressure chamber on so that when the door is opened the auxiliary piston is compressed the closer spring can be moved.
  • a closed in normal operation however, an electromagnetically actuated shut-off valve prevents movement of the additional piston in the opposite direction, so that the tensioned closer spring Closing force cannot be transferred to the closer shaft. Only when deactivated of the check valve in the event of fire, the blocking of the closer spring by the Additional piston released and the door leaf closes.
  • a disadvantage of this version is the complex structure of the locking cylinder.
  • high demands to the tightness of the hydraulic device for example, an unwanted to prevent creeping and gradual closing.
  • US 4,102,005 describes a force-transmitting linkage for a sliding arm door closer with a piston-cylinder unit and a closer spring.
  • the Door closer is equipped with a hydraulic locking device, which the piston and the closer shaft by interrupting the hydraulic circuit notes.
  • the linkage is made in two parts with an additional articulated connection between a base part and an extension part.

  • the additional joint connection allows free opening and closing of the door despite the hydraulic lock being switched on, which is only limited by a stop shoulder on the basic linkage is. If a fire alarm is triggered, the hydraulic lock is canceled, and the base link comes into contact with the stop shoulder the extension linkage. This is the extension linkage with the Closer coupled, and the door closes under the action of the closer spring.
  • the object of the invention is to provide a drive for a wing of a door, one To create windows or the like, with a freewheel function in normal operation and a locking function in an emergency, which is simple and in essentially allows the use of conventional piston-cylinder units.
