Definitions

  • the invention relates to a door closer linkage for the connection between the closer shaft of an overhead door closer and the door leaf or door frame, with a main arm and an adjustment arm connected to it in an articulated manner, which comprises a receiving rod and an adjusting rod which is connected to it in an adjustable manner and which is guided telescopically in the receiving rod, wherein the actuating rod and the receiving rod can be connected to one another by a releasable locking piece using a safety element.
  • Door closer linkage can be adjusted in a wide range in order to be able to be adapted to the respective door situation, such as different lintel depth, connection point shift due to different door widths, etc.
  • a door closer linkage is known from DE-A 2006069, the adjusting arm of which is formed from a receiving rod and an adjusting rod.
  • the tubular receiving rod has clamping fingers formed by slots which can be pressed against a roughened surface of the adjusting rod by a union nut.
  • the mounting rod and the actuating rod are thus connected to one another only by frictional engagement, so that it is doubtful whether the connection point is able to withstand the constant load intervals in the long term.
  • a tubular receiving rod and an adjusting rod inserted therein can be telescopically displaced relative to one another, the receiving rod having an elongated hole and being connected to the adjusting rod in a selectable position by a screw held therein.
  • the disadvantage of this embodiment is the material-weakening elongated hole, and it is also doubtful whether a clamping screw that creates only a non-positive connection secures the setting position, particularly in the case of high, intermittent closing forces.
  • the object of the present invention is to provide a door closer linkage which, without dismantling the connection point, can be adjusted quickly and, if necessary, also over large length ranges in a simple manner without great expenditure on components, and which are secured in the set position by a positive connection.
  • the actuating rod has a toothing on one longitudinal side of its shaft which corresponds to a toothing on at least one side wall of a section of the receiving rod encompassing the actuating rod and the locking piece engaging in the toothing with a toothing is arranged in the cutout of the receiving rod is.
  • the locking piece is comprised of a sliding tube which can be fixed on the articulated head of the actuating rod and which overlaps the actuating rod and the receiving rod and forms the securing member.
  • the sliding tube is preferably formed at its end facing the joint head of the actuating rod by two slots as a resilient tongue and provided within the tongue with an inward-pointing projection which can be snapped into a recess in the joint head of the actuating rod.
  • Such a sliding tube covering the receiving rod and the actuating rod prevents a release of the form-fitting connection of the actuating rod and the receiving rod in its securing position, since the locking piece is held in its connecting position and also gives the adjusting arm a pleasing, compact appearance.
  • the adjustment arm and the support rod of the door closer linkage can be formed from components with a round cross-section, it is advantageous for connecting the adjustment arm to a connecting joint for attachment to the door frame or to the door leaf and to form a joint head that can be connected to the main arm, if, as proposed according to a further embodiment of the invention, the receiving rod is designed as a tube with a rectangular cross-section and at its end opposite the connecting joint has a cutout formed by cutting a narrow side, in the area of which both longitudinal walls are provided with a corresponding toothing, and the locking piece with the narrow side of the receiving rod has the same width over which one matches the toothing of the adjusting rod and the receiving rod extending toothing extends.
  • the locking piece advantageously has a swivel bead following its toothing, which is articulated in recesses in the longitudinal walls in the region of the cutout of the receiving rod intervenes.
  • the door closer linkage comprises a main arm 10 and an adjusting arm 11, which are pivotally connected to one another via a joint head 12 located on the adjusting arm and a pin 13 located on the main arm with the interposition of a bearing sleeve 14.
  • the joint head 12 is part of an actuating rod 15 which, following the joint head 12, has a shoulder 15 with a rectangular cross section, to which an adjusting rod 16 is connected, which - as can be seen in particular from FIG. 3 - has a double-T-shaped cross section having.
  • This adjusting rod 16 is finally encompassed by a rectangular tubular receiving rod 17, which is fork-shaped at one end and is movably connected to a connecting joint 18 via a pivot pin 19.
  • a connecting shoe 20 is pivotally mounted on the connection joint 18 and can be screwed to a door leaf or a door frame, for example.
  • the adjusting rod 16 On a narrow side, the adjusting rod 16 has teeth 21 along its entire length.
  • the rectangular tubular receiving rod 17 has on one of its two narrow sides a cutout 22 which extends in the longitudinal direction in some areas, the longitudinally extending contour of which is designed as toothing 23 on both side walls 24 of the receiving rod 17.
  • the toothings 21 and 23 are identical in shape and dimensions, so that with the corresponding longitudinal position of the adjusting rod 16 relative to the receiving rod 17, these toothings can be placed congruently next to one another.
  • an essentially corresponding to the wall thickness of the cutout locking piece 25 is embedded, which is also provided on its side facing the actuating rod 16 and the side walls 24 of the receiving rod 17 with a toothing 26 which is in shape and dimensions with the toothing 21 and 23 match.
  • the width of the locking piece 25 corresponds to the width of the receiving rod 17 comprising the actuating rod 16, so that in the engaged position the locking piece 25 engages with its toothing 26 in the toothing 21 of the adjusting rod 16 and the toothing 23 in the side walls 24 of the receiving rod 17.
  • the adjusting rod 16 is fixed relative to the receiving rod 17 and the distance between the joint head 12 and the connecting shoe 20 is adjusted.
  • the receiving rod 17 is enclosed by a sliding tube 27 which holds the locking piece 25 in the connecting position with the adjusting rod 16 and the receiving rod 17.
  • the sliding tube 27 is somewhat shorter than the distance between the connecting shoe 20 and the joint head 12 in the pushed-together state of the adjusting rod 16 and the receiving rod 17 in order to be able to push the sliding tube 27 back so far that the connection position between the locking piece 25 and actuating rod 16 and receiving rod 17 can be removed.
  • a recess 28 is arranged on the extension 15 of the actuating rod 16 on two mutually opposite sides, into which the projection 29, which is resiliently formed on the slide tube 27 by slots 33, can snap into place.
  • the sliding tube 27 fulfills the function of a securing member.
  • the blocking piece 25 In order to hold the blocking piece 25 on the adjusting arm 11 during the adjustment of the adjusting rod 16 and the receiving rod 17, the blocking piece 25 has a swivel bead 30 following its toothing 26. This swivel bead engages in semicircular recesses 31 in the side walls 24 of the receiving rod 17. To release the locking piece 25 from a locking connection, the sliding tube 27 is only pushed back so far that the locking piece 25 can be pivoted out of the teeth, but the sliding tube 27 in the area of the swivel bead 30 still remains over the locking piece 25. So that the pivoting movement of the locking piece is made possible, a groove 32 which enables the pivoting is provided on the outside of the locking piece in the region of its pivoting bead 30.
  • the sliding tube 27 acting as a securing member is first released from its latching connection 28, 29 and pushed back so far from the joint head 12 that the locking piece can swing out of its engagement position and only remains with its swivel bead 30 in the recess 31.
  • the control rod 16, which is designed as a toothed rack, can now be pushed in or out as far as desired and can be positively connected to the tubular receiving rod 17 again in the desired length setting of the adjusting arm 11.
  • the sliding tube is then pushed back towards the joint head 12 until it engages over its shoulder 15 and engages with its projections 29 in the recess 28 of the shoulder 15.
  • the set position between the adjusting rod 16 and the receiving rod 17 is thus secured and the entire adjusting unit is covered, so that the exterior of the adjusting arm 11 is pleasing.
