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 articulated connecting arm, which has a receiving rod and an adjusting rod connected to it in an adjustable manner.
  • Door closer rails 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.
  • adjusting door closer linkages For adjusting door closer linkages, it is known to form the adjusting arm from a receiving rod having an internal thread and from an adjusting rod which can be screwed into it with an external thread. In order to adjust the length of such an adjustment arm, it is necessary to separate the door closer linkage with its link piece from the door leaf or door frame on site, in order to then screw the adjusting rod out of the receiving rod or into the receiving rod in a more or less lengthy operation.
  • the receiving rod and the actuating rod can be moved relative to one another, one of the two rods having a row of holes and being connected to the other rod by screws in selectable positions.
  • a disadvantage of this design, apart from the inconspicuous shape, is on the one hand the material-weakening row of holes and on the other hand the time-consuming adjustment process, since the connecting elements have to be completely loosened and removed from the holes in order to achieve an adjustment of the adjustment rod relative to the receiving rod.
  • the object of the present invention is to provide a door closer linkage zan Schemee without disassembly quickly and, if necessary, even over large L easily be adjusted without major component count.
  • the telescopically guided and mutually displaceable receiving rod and adjusting rod can be connected to one another by a releasable locking piece, the connection position of which can be determined by a securing member.
  • the adjusting rod By simply releasing the locking piece, the adjusting rod can be moved into the desired position relative to the receiving rod without the connecting joint of the adjusting rod needing to be dismantled. Tools are also not required for the required length adjustment of the adjustment arm.
  • the actuating rod has a toothing on one longitudinal side of its shaft, which is toothed on at least one side wall of a section of the actuating rod engaging receiving rod coincides, the locking piece engaging in the toothing with a toothing being arranged in the cutout of the receiving rod.
  • the blocking piece is encompassed by a sliding tube that can be fixed on the articulated head of the actuating rod and extends over the actuating rod and the receiving rod.
  • the sliding tube is preferably formed at its end facing the joint head of the actuating rod by two slits as a resilient tongue and provided within the tongue with an inward projection which can be snapped into a recess on the joint head of the actuating rod.
  • Such a slide tube covering the receiving rod and the adjusting rod prevents its securing position from releasing the positive connection of the adjusting rod and the receiving rod via the locking piece 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 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 extends a toothing that matches the toothing of the adjusting rod and the receiving rod.
  • the locking piece advantageously has a pivoting bead following its toothing, which articulately engages in recesses in the longitudinal walls in the region of the cutout of the receiving rod.
  • the door closer linkage comprises a main arm 10 and an adjusting arm 11, which 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 are pivotally connected to each other.
  • the joint head 12 is part of an actuating rod 15 which, following the joint head 12, has a shoulder 15 which is rectangular in 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 .
  • 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 connecting 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 section 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 a corresponding longitudinal position of the actuating 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 adjusting rod 16 and the side walls 24 of the receiving rod 17 with a toothing 26, the shape and dimensions of the toothing 21 and 23 match.
  • the width of the locking piece 25 corresponds to the width of the receiving rod 17 comprising the adjusting rod 16, so that the locking piece 25 in the engaged position with its toothing 26 engages 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 closed 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 selectively on the slide tube 27 by estimates. 33 resiliently molded projection 29 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 swiveling movement of the locking piece is made possible, on the outside of the locking piece in the region of its swivel bead 30, a groove 32 which enables pivoting is provided.
  • 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 pivot out of its engagement position and only with its swivel bead 30 in the recess 31 remains.
  • 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 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 to the eye.
