Definitions

  • the present invention relates to a door drive unit for the leaf of a door, window and the like.
  • the drive unit known from DE 19500944 C2 aims for a maximum closing torque at a minimum opening angle of a door, which torque continuously decreases as the opening angle increases. With this known device, this is achieved by continuously changing the lever acting on the drive shaft.
  • this publication shows a door drive unit for a leaf of a door, window and the like with an electromechanical motor, by means of which the leaf can be moved via a transmission box for coupling the motor shaft to the drive shaft, at least in the opening direction, via a drive shaft and with a closing spring configured as a spiral compression or tension spring by means of which the leaf can be moved in the closing direction via the drive shaft.
  • the closing spring and motor are arranged parallel to one another and at a distance from one another.
  • the drive shaft is provided with a cam disc which has various "levers" along the circumference.
  • a flexible force-transmitting element is partly wrapped around the cam disc and couples the latter with the displaceable spring cup.
  • a drive unit for a leaf of a door, window or the like comprising:
  • the drive unit for the leaf of a door, window or the like comprises the main drive device and the additional drive device.
  • the additional drive device may be designed to be completely mechanical and does not require any external power supply.
  • the spring means comprises for example a mechanical spring construction, such as a coiled spring, or a pneumatic or a hydraulic piston/cylinder assembly, such as a gas spring.
  • the spring means can also be designed differently.
  • the leaf has two extreme positions: a closed position and an open position.
  • a starting position one of the extreme positions of the leaf
  • the tumbler member is in the waiting position and the spring means exerts a torque on the tumbler member in the first direction, that is to say clockwise or counterclockwise.
  • the main drive device subsequently drives the leaf from the starting position to the other extreme position (final position).
  • the tumbler member is carried along by the rotating movement of the drive member and brought into the operating position.
  • the additional drive device is thus engaged by the drive member.
  • the spring means exerts a torque on the tumbler member in the second direction, counter to the first direction.
  • the tumbler member and the drive member are connected to one another for transmitting the torque exerted on the tumbler member to the drive member, so that the leaf is pushed into the final position.
  • the tumbler member When moving the leaf out of the final position, the tumbler member is returned to the waiting position.
  • the tumbler member By rotating the drive member from the second position to the first position, the tumbler member can be pivoted, counter to the pretension of the spring means, about the second rotary shaft from the operating position to the waiting position.
  • the first position of the drive member can correspond to an open leaf and the second position of the drive member can correspond to a closed leaf, with the rotation of the drive member from the first position to the second position defining a closing direction, and the rotation of the drive member from the second position to the first position defining an opening direction, and with the first direction of the torque exerted on the tumbler member being equal to the closing direction of the drive member, and with the tumbler member being pivotable from the waiting position to the operating position in a direction of rotation which is counter to the closing direction of the drive member.
  • the torque which is exerted on the tumbler member by means of the pretensioned spring means is in this case transmitted to the drive member for exerting an additional closing torque on the drive member in the closing direction.
  • the additional drive device ensures that a closed leaf which is connected to the drive member remains closed.
  • This is, for example, suitable for a fire-resistant swing door.

In the dead point position, the second, third and fourth pivot axis are aligned according to a substantially straight line. In the waiting position and the operating position, the spring means and the second arm portion of the tumbler arm enclose an angle which is between 150° and 180°.
