If the rear end of the door leaf in the course the closing movement is accelerated again after braking, the Restoring force of the compression spring is available to support this acceleration. On in this way a load change in the area of the traction means is prevented particularly reliably or reduced because the generation of the biasing force of the biasing means is immediate is coupled to the relative movement of the door leaf with respect to the traction means.

It has been shown that with this coupling of the drive device to the deflecting element, the weight of the in the open position in generally slightly inclined downward, when closing first or in the The closed position of the bottom door leaf element can suffice to move between the deflecting element and the point at which the traction device is attached to this door leaf element, arranged tension member section to tighten and the closing movement of the door leaf to cause corresponding actuation of the drive device.
  • the traction means in positive engagement with the Deflection element stands, the traction means in the form of a chain and the deflection element in Form of an associated sprocket or sprocket can be realized because of this way a particularly effective mechanical decoupling between the individual Sections of the traction device can be produced and on the other hand a slip-free Drive is possible.

  • the coupling of the drive device to the Deflection element the automatic initiation of the closing movement of the door leaf when appropriate Activation of the drive device or release of the traction means favors.
  • the inertia mostly over head and horizontally aligned door leaf due to the weight of the first, at the closing movement, obliquely downwardly inclined door leaf element in some cases can not be overcome, so that an actuation of the drive device does not automatically lead to the initiation of the closing movement. Because of this, can there is a loosening of the traction means tension when the drive device is actuated, especially in the area between the deflecting element and the attachment point of the Come pulling on the door leaf.

  • This aspect of the invention is based on the incredibly simple knowledge back that the closing movement is not just using an additional pull rope can be triggered reliably, but also when the pulling rope is needed anyway a thrust element acting as a driver is attached.
  • This can Aspect of the invention with particular advantage in those already explained above Gates are used with a drive device acting on the deflection element, because the one running approximately parallel to the horizontal guide rail section Pull rope section when driving the door in any case in the direction of the closed position the gate is moved, while a loosening of the traction means or a slack rope only in Area of the vertical traction section can occur.
