Definitions

  • the invention relates to a door closer whose extension arm is rotatably connected at one end to the door closer drive shaft and the other end or the like in a fixed frame.
  • the slide rail attached to the door carries at least displaceable, preferably lockable in an open position sliding element, a bearing pin or the like. is rotatably mounted in the sliding element at the end of the extending arm on the sliding element and the bearing pin can be connected to the sliding element in a snap-in or latching manner.
  • a door closer is known from document US-A-4 837 890. It is preferably a so-called overhead door closer that is attached to the door leaf. When the door is opened, the extension arm, which runs approximately parallel to the door leaf level when the door is closed, is pivoted, the sliding element then being moved along the slide rail. When the door is released, all deflected or moved parts are returned to their original position.
  • the extension arm When the door is closed, the extension arm is under a pretension that wants to push it away from the fixed frame.
  • This pretension comes from a spring of the door closer, which, as mentioned, loads the opening arm, which is arranged approximately parallel to its plane, in the direction of its inclined position when the door is closed. This spring force makes the assembly of the door closer, slide arm and slide rail more difficult.
  • assembly has been carried out, for example, by connecting the slide arm to the slide piece on the slide rail prior to its installation and then mounting the slide rail on the fixed frame while overcoming the force of the door closer. This can usually only be done by two people. After all, the torque on the closer arm is approximately approx.
  • Sliding element are either bent, or the pivot bearing would have to be stressed in an impermissible manner.
  • the invention proposes that the door closer according to the preamble of claim 1 is characterized in that the sliding element has a fork-like receptacle for the bearing pin, the fork legs of the receptacle being elastically spreadable and extending transversely to the bearing pin.
  • the slide rail is mounted on the fixed frame.
  • the slide is then attached to it and moved to a position suitable for connection with the bearing pin.
  • the latching or snapping connection of the bearing pin to the sliding element is carried out, the door closer being of course fastened to the door leaf at this time.
  • the snap or snap connection must be such that the door closer forces cannot overcome it, i.e. this connection cannot come loose by itself even when the door is closed. If necessary or appropriate, this connection can of course be secured in a suitable manner.
  • a development of the invention provides that the snap or latching connection of the bearing pin to the sliding element can be secured by means of a securing element.
  • the latter must be designed and constructed in such a way that it can be attached in a simple manner and withstands all forces that arise.
  • the securing element and the sliding element can be connected snap-in or latching, so that no tools are required for attaching the securing element.
  • a particularly preferred embodiment of the invention is that a latching on the fixed frame opposite end of the sliding element with the door open locked with a resiliently deflectable, adjustable in the longitudinal direction of the slide locking element.
  • the slider can also be used advantageously for locking purposes.
  • a door 2 is rotatably mounted on a fixed frame 1 about a vertical axis 3 in the sense of the double arrow 4.
  • a pivot bearing 5 can be seen.
  • a door closer 6 with an opening arm 7 is mounted on the door. The latter can be pivoted about an axis of rotation 8 of the door closer 6 in the sense of the double arrow 9.
  • the end 10 of the extension arm 7, which protrudes somewhat from the plane of the fixed frame in FIG. 2, is coupled in the manner described below according to the invention with a sliding element 11 (FIG. 3) which can be displaced along a sliding rail 12.
  • the direction of displacement is designated by 13 in FIG.
  • the opening arm 7 assumes the position shown in FIG. 2 due to a spring force of the door closer 6.
  • the door closer 6 can be conveniently attached to the door 2 by a mechanic.
  • the connection is such that the rotation of the bearing pin 17 in the corresponding receptacle 18 of the sliding element 11 is possible when the door is opened.
  • the receptacle 18 is fork-shaped, the Bearing pin 17 between the two fork legs 19 and 20 engages.
  • the bearing pin 17 engages they are spread apart for a short time in a spring-elastic manner.
  • Each fork leg carries at its free end a thickening 21 or 22 behind which the bearing pin 17 engages and which, with the aid of bevels, cause the spring-elastic spreading.
  • the receptacle 18 has a cross-sectional shape which corresponds approximately to a cut-off bearing bore with a circular-cylindrical cross section.
  • the bearing pin 17 has a pin section 24 with a reduced cross section, the length of which corresponds approximately to the length of the receptacle 18, measured in the same direction.
  • a thickened head 25 of the bearing pin 17 thus formed protrudes upward.
  • the height of the fork legs 19 and 20 at Embodiment chosen shorter than the height of the sliding element 11 measured in the same direction or in the longitudinal direction of the bearing pin 17.
  • the narrowing of the cross-section of the bearing pin 17 has the effect that it is held on the sliding element 11 so that it cannot move in its longitudinal direction.
  • FIG. 3 also shows that the slider 11 has a central region formed by the fork-like receptacle 18, to which end regions with a bar 26 and 27 are connected on the left and right. These strips extend essentially parallel to the fork legs 19 and 20. The distance of each strip from the associated fork leg is selected so that a U-leg 28 or 29 of the securing element 23 can engage and engage therein. At the free ends of the U-legs 28 and 29 there are longitudinal beads 30 and 31 on the inside, i.e. these two longitudinal beads face each other. Each engages behind or snaps behind an outer longitudinal bead of the associated fork leg 19, 20 which projects in the opposite direction, this being formed by the outer edge of the thickening already mentioned at the free fork leg end.
  • the snap or latching connections of the bearing pin 17 with the sliding element 11 on the one hand and the securing element 23 with the sliding element on the other hand ensure a secure connection of the extension arm 7 to the sliding element 11, which connection enables the necessary movements and can withstand all loads that occur.
  • a lever 33 of a locking element 34 latches when the door 2 is correspondingly opened wide.
  • the latter is in the longitudinal direction the slide rail 11 on and lockable.
  • the lever 33 is a two-armed lever, one of which has a lever arm 35 which projects beyond the housing 36 of the locking element 34 and which carries a catch 37 which points towards the slide rail 12. It can engage resiliently in the latching receptacle 32 as soon as the sliding element 11 has approached the locking element 34 sufficiently far or is just in front of its housing 36.
  • the other lever arm 38 of the lever 33 bears against a run-up slope 39 of a slide 40.
  • the incoming sliding element 11 pivots the lever 33 in the direction of arrow 41 about its axis 42
  • the preferably spherical or beaded free end of the lever arm 38 presses against the ramp 39.
  • the slide 40 becomes counter to the action of a return spring 43 in Arrow direction 44 shifted.
  • the return spring 43 presses the slider 40 back at least by a small amount. The remaining spring force is sufficient to secure the latching connection 32, 37.
  • the inner end of the return spring 43 is supported on the bottom of a blind hole 45 of the slide 40.
  • the outer end abuts a collar 46 of an adjusting member 47.
  • this is equipped at its outer end with a threaded pin 48 which can be screwed into a corresponding nut thread of the housing 36 and for this purpose preferably has a hexagon socket.
  • the spring tension can be increased by screwing in the adjusting member 47.
  • the cross section of the slide 40 is preferably rectangular in order to avoid rotation in the housing 36. It can be seen from FIG. 6 that the housing 36 has on its rail-side back a longitudinal groove 49 that extends at least over a partial length and that narrows on the outside. Furthermore, it can be seen from FIG.
  • the slide rail 11 in the exemplary embodiment has a double-T-shaped cross section with preferably unequal legs.
  • the sliding element 11 is pushed onto the narrow leg 50 of the double-T profile in the exemplary embodiment by means of its longitudinal groove 49.
  • the dimensions are chosen so that the sliding element 11 is approximately flush with the longitudinal edges of the wide Leg of the double-T profile runs. This then enables the cover to be covered by means of a cover rail 51 without any problems.
  • FIGS. 5 and 6 show that the free, opposing leg ends 52 and 53 form the narrowing of the longitudinal groove 49 on the back of the housing 36, these webs according to FIG. 5 being interrupted.
  • the dimensions are chosen so that the thickness of the webs 52 and 53 corresponds approximately to the space between the two legs 50 and 54 of the sliding element 11.
  • a clamping screw 55 (Figure 5), which can be screwed into a nut thread of the housing 36 and has a pointed end and a hexagon socket in a known manner, is used to fix the housing 36 or the locking element 34 on the slide rail 12 in the predetermined displacement position. After loosening the clamping screw 55, you can move the housing 36 and thus choose a different locking opening width of the door 2.
  • the door closer In a so-called complete assembly, in which the door and the door frame are equipped in the workshop with the door closer 9, the door closer can be installed with the door closed. By using the locking device for the open door, any door buffers that may be necessary can be avoided.
  • the slide rail 12 and the cover rail 51 can be sections of so-called yard goods.
  • the slide rail 12 only has to be provided with fastening holes. These are unnecessary if you take a piece of goods that has such holes at predetermined intervals.
  • the door closer is preferably a so-called overhead door closer with a sliding arm. It is characterized by a particularly low overall depth.
