  • the drive systems can be designed such that the shafts can be driven with separate motors.
  • the invention has for its object a drive system for a lamella arrangement provide which is easy and inexpensive to install and with which a safe, precise and fault-prone adjustment the fins can be carried out.
  • the invention relates to a drive system for a lamella arrangement a motor-driven drive linkage running in a stationary mount and with gears arranged in the receptacle.
  • Any gear has a bearing journal mounted in the receptacle, in which at least a shaft of a lamella is supported.
  • the bearing journal is by means of a Worm wheel, which can be operated via the drive linkage, for position adjustment the slat rotatably mounted.
  • a Worm wheel instead of a worm wheel also a spur gear, a gear train or the like can be used.
  • the drive linkage is preferably driven by means of an electric drive.
  • Gearboxes can change the position of several slats synchronously become.
  • the drive system designed in this way has an extremely inexpensive, modular Building on.
  • the drive linkage and the gearbox are space-saving in the mount integrated, which is preferably formed by a profile tube.
  • Another advantage of this arrangement is that by the storage the trunnion in the receptacle runs the drive linkage in this receptacle is decoupled from the slats. This affects through temperature fluctuations caused changes in length of the drive linkage not on the movements of the slats. This also applies to existing ones Temperature fluctuations an exact uniform and synchronous run of the Get slats. Finally, the drive system according to the invention is insensitive against temperature-related changes in length of the profile tube.
