  • the invention relates to an electromechanical swing door drive with a door closer.
  • DE 41 24 282 C2 describes an electromechanical swing door drive in which an electric motor - possibly with the interposition of a clutch - drives a transmission which is connected directly or with the interposition of a gear train to a closer shaft of a door closer.
  • the door closer can be designed as a slide rail door closer. Since the electric motor acts directly on the closer shaft of the door closer via a gear train or several gear trains, additional pulse generators, timers, detectors and limit switches controlling the electric motor are required to achieve the required opening and closing characteristics.
  • manually operable slide rail closers in which a piston guided in the housing and supported against a closing spring is provided, a toothed pinion arranged on the closer shaft meshing with a toothed rack of the piston.
  • slide rail closers also known as pinion closers
  • pinion closers have the advantage over conventional door closers that they have no linkage that projects freely into the room, but only an actuating arm lying flat against the door frame or door leaf, which interacts with a slide that can be moved in a slide rail ,
  • the actuating arm lying flat on the door frame or door leaf in conjunction with the conventional, symmetrical pinion mechanism leads to an unfavorable force curve on the door.
  • There is therefore a desire for an optimal design of the pinion so that the pinion on the associated rack and pinion runs as smoothly and smoothly as possible during the opening and closing process of the door to achieve the piston in the piston housing, which also corresponds to an ideal torque curve.
  • a door closer with an eccentrically mounted pinion has become known from EP 0 856 628 A1, the toothing of the toothed rack forming a linear rolling line running at an angle between 4.5 ° and 7.2 ° to the direction of movement of the piston.
  • the choice of the angle depends on the size of the door closer or the force of the closing spring.
  • An eccentrically mounted pinion is also shown in DE 36 45 313 C2 and DE 36 45 314 C2 using a pitch curve arranged on the pinion with different lever arms to the axis of rotation.
  • the pitch curve of the assigned rack is correspondingly curved.
  • the closer shaft is connected to an eccentrically mounted elliptical gear that meshes with an oblique rack on the piston side. Due to the different long lever arms of the elliptical gearwheel, a translation adapted to the desired torque curve to a certain extent is achieved by means of the elliptical gear.
  • the pneumatic door closer according to US Pat. No. 1,359,144 has a circular, eccentrically mounted pinion, which meshes with an odd toothed rack on the piston.
  • the circular pinion is provided with regular teeth on a circular pitch curve, where with different lever arms due to the eccentric bearing.
  • EP 0 056 256 A2 Centrally mounted pinions are known from EP 0 056 256 A2 and from EP 0 350 568 A2.
  • EP 0 056 256 A2 is concerned with a door closer, the piston of which has two mirror-symmetrically opposite toothed racks, a centrally mounted pinion in the closed position with shortened teeth engaging in both toothed racks of the piston.
  • the door closer according to EP 0 350 568 A2 has a centrally mounted pinion, which has teeth with a progressively increasing tooth height that extend over the circumference and engage between the rods of a correspondingly curved toothed rack.
  • DE 44 44 131 A1 and DE 44 44 133 A1 disclose essentially centrally mounted pinions of a drive for a door or a window, the pinion itself having toothing over approximately half its circumference, the teeth of which are arranged on and on lever arms of different lengths a correspondingly curved pitch curve of a rack.
  • the object of the invention is to use a electromechanical drive for the opening process of the connected door, the closing process not to be realized by the electromechanical drive but by an energy store (power transmission unit) to create a small and inexpensive swing door drive which demanded opening and closing characteristics as guaranteed with a sliding arm door closer, ie the movement of the piston of the door closer during the opening and closing process within the To optimize the door closer housing, ie in particular to ensure a pinch-free and therefore low-friction running of the pinion on the rack of the piston.
  • an improvement in the closing characteristics of the slide rail closer is to be additionally achieved by an improvement in the oil exchange from the piston chamber to the spring chamber during the closing process.
  • either a device which essentially consists of individual modules of a door closer, transmission and motor or a whole which contains a motor, a transmission and a power transmission unit in a housing, the power transmission unit including the functions of a door closer.
  • a rack or its teeth are optimally adapted to the course of a toothing of a pinion, taking into account its eccentric bearing and its circular rolling curve, so that a smooth transition to the next tooth in each case during the opening and the closing process is guaranteed. This applies in particular to the area of the pinion which exceeds the rotation by 180 °.
  • a separate door closer it preferably has a two-sided axle outlet, one axle outlet being used to connect a lever that interacts with a slide rail via a slide, and the opposite axle outlet is used with a power transmission element in a manner known per se with the transmission a corresponding motor is connected.

  • a corresponding mounting plate here, which allows the individual modules, such as. B.
  • Door closer gear and motor can be designed individually to ensure flexible replacement in the event of a defect in individual modules.
  • the rotation of the pinion from the closed position to the maximum open position can be more or less than approximately 180 ° without adversely affecting the required efficiency.
  • any tooth shapes can be used in an embodiment of the invention; d. H. the pinion and / or the rack can have teeth with straight, angled or convexly curved tooth flanks.
  • the invention also includes an improvement in the oil exchange between the piston spaces separated by the piston.
  • different closing phases can be assigned to the closing process of the connected door. This can e.g. B. two or four closing phases with different speeds of the door leaf. As very comfortable B. proved four closing phases.
  • the closing process then comprises four closing phases, each closing phase being assigned a closing angle in a manner known per se, including a certain tolerance.
  • both the first and the third closing phase can be controlled by means of a single valve, so that the achievable low-friction sequence of the pinion on the rack is supported by an advantageous configuration of the oil exchange from the piston chamber to the spring chamber during the closing process, a valve usually required for the third closing phase can be dispensed with.
  • a swing door operator is to be regarded as an opening aid, the closing process of the door z. B. is realized by the door closer described above.
  • a door closer which is equipped with a cam disc, can also be used, but much higher powers are required for the drive motor, which would inevitably lead to an increase in price and an increase in the rotary leaf drive.
