Definitions

  • the invention relates to a door closer according to the preamble of claim 1.
  • Such a door closer has become known under the name "DORMA TS 77" and has proven itself in practice by its reliability and the many applications.
  • the door closer can be mounted on the inside or outside of a door leaf as well as on a door frame.
  • the arrangement of the door closer on the inside of a door leaf is fundamentally problematic because the door leaf is moved when opening in the direction of the adjacent wall and the door closer is then located between the door leaf and this wall. So there is a danger that the door closer at too large opening angle of the door leaf abuts against the adjacent wall and is damaged, especially if the door is installed in a corner or a thick wall. In such applications, a limitation of the opening angle is appropriate. Desirable are therefore compact door closer with the lowest possible height while maintaining the previous variety of applications and different functions.
  • the outer dimensions, in particular the height of the known door closer are very high due to the special internal structure, so that for the packaging of the door closer according to much packaging material is required and the other appropriate storage and transport space must be available.
  • the edged outer shape of the door closer creates manufacturing problems through material cavities and is not optimal under the aspect of an economical use of materials.
  • the invention has for its object to improve a door closer according to the preamble of claim 1 so that a compact and visually appealing unit is created, which can be produced with minimal material and manufacturing costs.
  • the subject matter of claim 1 has the advantage that a low overall height can be realized by the compact outer shape of the door closer.
  • the door closer is therefore also suitable for use in confined or unfavorable installation situations with regard to a restricted opening angle of a door leaf.
  • a door closer is to be preferred, the mechanical and hydraulic units are arranged in the longitudinal direction in a corresponding channel of the body.
  • the material requirement for the body according to the invention is extremely low, the stability and all functional properties are guaranteed. All wall thicknesses are reduced to a minimum.
  • the resulting outer contours are made visually appealing by flowing and seamless transitions.
  • the body is elongated through the array of functional units, with the side surfaces conforming to the contours of the channel. Ideal is a curved or oblique course of the side surfaces.
  • the exit points of the drive shaft are sufficiently stable, the side surfaces of block-like massive reinforcements, which in turn are designed to save material. Particularly advantageous is the connection of these so-called bearing blocks on the underside of the body.
  • the drive shaft is arranged so that different mounting positions of the door closer can be realized.
  • the shaft is very material-saving and easy to install stored and secured in the corresponding axle hole.
  • the reduction of the outside dimensions reduces the amount of packaging materials required and reduces the storage and transport space.
  • the reduction in volume and weight increases packing density during transport and also makes handling easier for on-site assembly workers.
  • the properties mentioned also contribute significantly to the reduction of manufacturing costs.
  • the door closer 1 shown in the figures are manufactured in one piece in a casting process and consist for. As aluminum or steel. Despite the aspect of optimizing minimal material use with sufficient body stability, no solid body 2 is created. Basically, all outer contours and surface transitions are rounded.
  • the door closers 1 are each equipped to receive a mechanical and a hydraulic functional unit, which are arranged to reduce the height in a known manner in the longitudinal extension of the body 2 in a channel 21.
  • a shaft 22 connects the mechanical unit in the body 2 with a linkage outside the body 2.
  • the shaft 22 is guided on both sides of the body 2 to the arrangement of the door closer 1 and the linkage, relative to a door leaf and a door frame in dependence to handle the assembly conditions variable. For clarity, the linkage is not shown.
  • a piston 23 and a closer spring 24 are slidably coupled to each other.
  • the shaft 22 is rotatably mounted in the body 2 and has centrally a gear 25 which cooperates with a toothed rod 26 formed integrally within the piston 23.
  • the shaft 22 is coupled outside the body 2 with the linkage, not shown.
  • the body 2 has an axially aligned axle bore 27 for supporting and securing the shaft 22.
  • the axle bore 27 has a round cross-section.
  • the Indian FIG. 5 Upper part of the axle 27 has a cross-section narrowing edge 28.
  • the lower part of the axle 27 has a groove 29 for a sealing ring 30.
  • the shaft 22 is symmetrical and has the center of the gear 25. On both sides of the gear 25 discs 31 are pre-assembled. At both ends of the shaft 22 devices for attachment of a linkage are formed. The linkage is installed at the appropriate end depending on the installation situation.
  • sintered bushes 32, 37 made of ceramic material.
  • a tubular bearing shell 33 has a stepped cross section, which ends in a peripheral edge 34. The outer surface of the bearing shell 33 is at least partially radially enlarged.
  • the bearing shell 33 forms a preassembled unit, in which first a ring seal 35 is pushed against the peripheral edge 34 and then the sintered sleeve 32 is pressed inextricably against the annular seal 35.
  • a ring seal 36 and then the sintered bushing 37 is fixed inextricably.
  • the sealing ring 30 is inserted in the groove 29 of the lower part of the axle 27.
  • the shaft 22 is inserted through the lower part of the axle 27.
  • the shaft 22 slides within the upper part of the axial bores 27 through the sintered bush 37 fixed therein until it abuts against the channel 21 with the disk 31.
  • the complete storage and attachment of the shaft 22 is effected by inserting the bearing shell 33 in the lower part of the axle bore 27.
  • the preassembled bearing shell 33 is pushed over the shaft 22 and finally positioned in the body 2 and on the shaft 22 by means of a defined pressure.
  • the sintered bush 32 slides over the shaft 22 and the outer surfaces of the bearing shell 33 along the inner wall of the axle bore 27.
  • the body 2 surrounding the axial bore 27 is pressed elastically outwards. After passing through the groove 29, the projection hooked by spring back of the body 2 in this groove 29 and the bearing shell 33 is fixed.
  • the shaft 22 is also positioned axially by contact of the sintered bushing 32 on the disk 31.
  • the body 2 is in principle elongated. He has over a bottom 4 on an upper surface 3.
  • On the bottom 4 mounting plates 9,10 are formed in the longitudinal direction, which serve for fastening of the body 2 to a door leaf or a door frame.
  • the bottom 4 and the top surface 3 are in longitudinal extension connected by side surfaces 5,6. End faces 7, 8 are arranged perpendicular to the side surfaces 5, 6 and to the underside 4 and the upper surface 3 and delimit the body 2 in the longitudinal extent.
  • the mounting plates 9,10 protrude from the body 2 at the end faces 7,8.
  • the embodiment according to the Figures 1-3 has the following peculiarities.
  • the side surfaces 5,6 extend starting at the bottom 4 with a body-directed curvature and terminate at the surface 3.
  • the curvature has a parabolic shape, wherein the upper surface 3 limits this course.
  • the transitions between the side surfaces 5,6 and the upper surface 3 are formed by small radii.
  • the shaft is arranged centrally between the upper surface 3 and the lower side 4 and off-center between the end faces 7,8.
  • This arrangement of the shaft 22 allows diverse, eg mirror-image mounting variants of the door closer 1. It occurs on both side surfaces 5,6 on bearing blocks 11,12 from the body 2.
  • the bearing blocks 11,12 are solid and integrally formed on the body 2, to ensure a stable shaft bearing.
  • the bearing blocks 11, 12 each have trapezoidal front surfaces 13, 14 which run perpendicular to the underside 4, with the broad base sides 15, 16 on the underside 4. This trapezoidal cross-section of the bearing blocks 11, 12 continues to increase slightly from the front surfaces 13, 14 to the side surfaces 5, 6.
  • the bearing blocks 11,12 are dimensioned so that they do not project beyond the upper surface 3.
  • FIGS. 6 and 7 a body 2 is shown, the side surfaces 5,6 also run parabolic.
  • the upper surface 3 is slightly bulged outward body, so that further casting material is saved.
  • the transitions between the side surfaces 5,6 and the upper surface 3 are also formed with small radii.
  • the bearing blocks 11,12 have U-shaped front surfaces 13,14, wherein the open sides 17,18 on the bottom 4 are.
  • the U-shaped cross-section of the bearing blocks 11, 12 increases slightly in the direction of the side surfaces 5.6.
  • the mounting plates 9,10 are chamfered for reasons of material savings.
  • FIGS. 8 and 9 a body 2 is shown whose side surfaces 5, 6 have different curvatures.
  • the side surface 5 extends as in the embodiment according to Figure 1-3 already described parabolic and adjacent to a flat top surface 3.
  • the side surface 6 has a different from the side surface 5 parabolic course, which is characterized in that the side surface 6 smoothly terminates in the upper surface 3.
  • the upper surface 3 is thus formed on one side flat and curved on one side.
  • All three embodiments have in common that they are at the bottom 4, as shown FIG. 3 can be seen two holes 19,20. These holes 19,20 are used during production after the casting process for centering and mounting of the workpiece at other machining sites. As a result, no misalignments of the workpiece can occur, especially in machine manufacturing.
