Definitions

  • the invention relates to a door closer according to the features of Claim 1.
  • a door closer which with a Slide rail linkage is provided.
  • One end of an arm of the The slide rail linkage is arranged on the door leaf Door closer hinged and the other end of the arm sliding in one Rail mounted on the door frame.
  • the door closer end of the arm is connected to an output shaft of a transmission that is connected to a Spring arrangement is coupled.
  • the gear consists of specially shaped Toothed cams with a pitch curve that is from different radii of the toothed cam discs that are constant in sections results.
  • One toothed cam is via the output shaft of the door closer with the end of the arm and the further toothed cam with an in connected to a rack engaging pinion of the door closer the rack against or with the bias of a spring of the spring assembly emotional.
  • the changing pitch curve of the two toothed cam disks is supposed to be the same counteracting the opening angle of the door leaf changing arm of the arm be so that the necessary for opening and closing Torque of the door leaf has a predetermined characteristic has the opening angle, in particular a falling opening torque sought.
  • EP 0 856 628 A1 discloses a door closer, the drive axle is connected to an eccentrically mounted gear. This gear combs his teeth within a straight line at an angle trending tooth area, within a piston, with a spring cooperates, is arranged. When turning the drive axle this results in lever arms that are effective for different lengths of time. This changes the force and torque curve.
  • the invention has for its object a door closer according to the specified type in such a way that avoiding the aforementioned Disadvantages stated a simple space-saving construction that is easy for the desired torque curve over the opening angle of the door leaf can be designed.
  • the invention is based on the finding that the opening angle the door changing force curve - torque curve - both when opening and closing via a device with a influenced by the gear ratio changing the opening angle can be that by eccentrically arranged and a circular ring gear having gears that is easy have it made.
  • this therefore relates to the opening angle of the door in its gear ratio changing gear a first and a second meshing, each by a circular ring gear formed gear on, while maintaining their center distance are eccentric to their centers and of which the first gear with an output shaft and the second gear coaxial to the fulcrum with the one coupled to the spring arrangement Rack engaging gear are connected, the axis of rotation the output shaft runs through the fulcrum of the first gear, all in such an arrangement that they are each through the center of a gear and the new pivot point resulting eccentricity of the gears is point symmetrical to their pitch point.
  • the torque curves can now be carried out in a simple manner Choice of the eccentricity, the pitch circle diameter and the resulting resulting distance of the axes of rotation of the two gears set and can be easily determined. This results in many Gear ratios and thus adjustment options to the desired Torque characteristics over the opening angle, without that custom-made toothed cams are necessary. Much more commercially available gears can be used, whereby the manufacturing costs decrease significantly. In addition, the gears in particular have a normal toothing.
  • the size of the eccentricity is determined by the ratio of the amount of the same described for the base circle diameter. In particular, this should Ratio a value of 0.137 for gears according to DIN 867 not exceed.
  • the door closer is as Overhead door closer with one between a pivot point of the rotating Door leaf of the assigned door and a further articulation point changing outside the door leaf over the turning range effective lever arm designed to engage the output shaft.
  • the effective lever arm is preferably by means of a slide rail linkage or formed a toggle linkage.
  • the door closer can also be designed as a floor door closer be in which the output shaft with the bearing of the door leaf interacts.
  • Figure 1 is a schematic view of a door closer 10 with gear 12 and spring arrangement 14 shown in a housing 16 of the door closer 10 are arranged.
  • the spring 14 is in a known manner via a guided in the housing 16 Piston 18 coupled to a rack 20.
  • Grips in the rack 20 a gear 22, which is fixedly connected to a gear 24, wherein the axis of rotation 26 of the gear 22 and the axis of rotation of the gear 24 are identical.
  • the gear 24 meshes with a further gear 28, the one with the housing 16 projecting output shaft 30 is connected.
  • the Output shaft 30 is arranged coaxially to the axis of rotation 32 of the gear 28.
  • the two gears 24 and 28 are provided with normal toothing and with respect to its central axis 34 or 36 around a predetermined one Amount e rotatably mounted eccentrically.
  • the axis of rotation 26 of the Gear 24 is thus from its central axis 34 and the axis of rotation 32 of the gear 28 spaced from its central axis 36 by the amount e.
  • a toggle lever or a can be connected to the output shaft 30 in a known manner Attack the slide rail linkage.
  • the door closer 10 can also as Bottom door closer can be formed, the output shaft 30 then with interacts a bearing of a door, not shown here.
  • the meshing gears 24 and 28 are related represented with an X-Y coordinate system, the X axis the two pivot points formed by the axes of rotation 26 and 32 38 and 40 connects together.
  • the through the central axes 34 and 36 Center points 42 and 44 formed each point to the assigned one
  • the pivot point 38 or 40 determines the distance e that determines the eccentricity.
  • the center points 42 and 44 relate to a circular toothed ring of the respective gear 24 or 28 with a circular base circle, Tip circle, pitch circle u. ä.
  • this is through the center 42 and the fulcrum 38 or through the center 44 and the fulcrum 40 formed eccentricity e point symmetrical to the pitch point 46 of the two meshing gears 24 and 28 by touch the two pitch circles 48 and 50 of the gears 24 and 28.
  • the gears 24 and 28 have a corresponding design on. This enables the gears 24 and 28 to rotate the distance from the pivot point 38 to the pitch point 46 increases increasingly the size increased or decreased, like the distance of the fulcrum 40 to the pitch point 46 decreases or increases. The distance of the Pivots 38 and 40 of the two gears 24 and 28 remain relative to each other here, however, while the gears 24 and 28 are rotating.
