  • Door drives of the type of interest here are used for actuating door leaves and are mounted on the door frame, on the lintel or an adjacent wall.
  • the door drive can also be mounted on the door leaf itself, in any case an actuation of the door leaf in the opening movement, in the closing movement or for both movements is possible.
  • From the gear of the door drive usually extends a closer shaft, which is connected to the harness of the door or via a linkage forms an operative connection with the door leaf.
  • the engine of the door drive can be designed as a simple spring energy storage and is in operative connection with the transmission.
  • Automatic door operators have an electromechanical or electro-hydraulic drive, which can be activated by a control to both open and close the door leaf.
  • a combination of an electromechanical or an electro-hydraulic drive with a spring energy storage device offers the possibility to carry out the closing movement of the door via the spring energy accumulator.

  • the DE 10 2006 040 231 A1 For example, describes an arranged on a motor output shaft incremental encoder.
  • the motor is gearless coupled with a drive pulley.
  • the arrangement of an incremental encoder on a drive motor output shaft has the disadvantage that when using a transmission between the drive motor and door drive output shaft additional space must be provided in the engine output shaft, which negatively affects the size of the door drive. Furthermore, an exchange of a defective incremental encoder is possible only by disassembling the drive motor, which makes the (dis) assembly difficult.
  • the DE 103 006 44 A1 describes an integrated in a transmission of a door drive pulse disc of an incremental encoder.
  • a combined crown spur or friction spur gear is used to transmit the rotational movement of a gear shaft to a separate pulse disk drive shaft.
  • This serves the purpose of spatially separating the pulse disc from the transmission.
  • This structure is, however, on the one hand very expensive.
  • the pulse disk arrangement must be closed to the outside to prevent the ingress of dirt particles, which makes the entire structure even more expensive.
  • the (de) mounting of the incremental encoder remains expensive.
  • the invention includes the technical teaching that the drive unit has a rotary encoder which provides information about the position and / or the movement of a door leaf via an electrical signal.
  • function errors and / or false states of the door can be determined on the basis of the angle data. This provides a possibility of recognizing an object which is located in the area of movement of the door leaf and blocks it from moving.

  • the rotary encoder can also be integrated into the transmission according to a further embodiment, so that the shaft does not have to extend directly out of the housing of the transmission.
  • the rotary encoder is also attachable to the engine, so that, for example, the motor has a rear shaft, which has the same rotational movement as the output shaft of the motor. Consequently, a rotary encoder can be provided, which is flanged on the rear side on the drive motor in a conventional manner. It is also possible to connect the rotary encoder with the closer shaft directly, so that the position and rotational speed of the closer shaft is detected directly.

  • FIG. 11 shows the in FIG. 10 invisible back of the mounting plate 26 in conjunction with the shaft 7.
  • the mounting plate 26 has on this side hub side arranged locking projections 29.
  • the latching projections 29 are so distributed on the circumference of an example 3 times the same and have inwardly facing locking lugs that they can engage in a locking groove 32 preferably by clamping, which is introduced on the shaft 7 of the gear 24.
  • the inner surface of the non-visible, in the direction of gear shaft facing collar-shaped projection 34 with the corresponding outer surface of the shaft 7 comes into clamping or driving engagement.
  • the shaft 7 is preferably provided at the end facing the mounting plate 26 with a cone, which facilitates the placement of the mounting plate 26 on the shaft 7.
  • the invention provides a very simple design and mounting angle detection for door drives, which is also universally applicable.
  • the invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use.
