Definitions

  • the invention relates to a door drive with the features of the preamble of Claim 1 and a method for producing a door drive.
  • Door drives with closer springs are known as energy stores and hydraulically damped closing movement, in which the closer spring with a hydraulic piston-cylinder unit interacts.
  • the piston-cylinder unit and the closer spring are arranged in a metallic housing and act on a rack and pinion or on Cam gear with a rotatably mounted in the housing Closer shaft together, which is direct or via a power transmission Linkage is connected to the door.

  • the housing of the door closer is used in practice cast from aluminum or made from extruded aluminum profiles. The Manufacturing effort is due to the required machining Post processing relatively high.
  • the hydraulic channels must be retrofitted into the Housing must be drilled and the cylinder chamber must also be reworked to ensure an exact fit of the piston.

  • This method is particularly suitable for the formation of longitudinal channels on the front of the housing for the use of the hydraulic valves to the outside.
  • the radial channels which connect the longitudinal channels to the cylinder chamber are preferred already formed without cutting in the manufacture of the housing.
  • the drive housing is made up of two housing halves manufactured, in each of which formed a longitudinal half of the cylinder chamber is. At the same time can in the adjacent surfaces of the housing halves Channels or channel sections of the damping device can be formed.

At the sliding arm door closer 3 can be a conventionally constructed one Door closer 3 act, for. B. a hydraulic door closer, as in DE 36 38 353 A1 is described.
  • Such a door closer 3 works in such a way that when opening the door leaf 1 by the resulting Forced movement of the linkage 5 and the closer shaft 4, the closer spring 7 is excited.

  • plastic offers various advantages that ultimately result in one lead to a significant reduction in manufacturing costs. Leave plastic parts inject themselves with much smaller tolerances compared to metal parts or pour. Thus, a higher one can already be made during the manufacture of the raw housing Fit can be achieved, which ultimately reduces the required rework. Another advantage is that most housing openings and housing bores already in the manufacture of the housing 31 through the use suitable injection molds can be inserted without cutting. An afterthought Machining holes e.g. for fastening or hydraulics can therefore be omitted. If postprocessing is nevertheless necessary or Should be desirable, this is much easier in the plastic housing accomplish than in the metal housing. It is also a two-component spray process possible two different plastics in one manufacturing process to process, e.g.
  • Suitable plastics for producing the door closer housing 31 are, for example flavored polyamides with a high glass fiber content to increase of firmness.
