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 due to its reliability and diverse application possibilities.
- the door closer can be mounted on the inside or outside of a door leaf as well as on a door frame Placing the door closer on the inside of a door leaf is fundamentally problematic since the door leaf is moved in the direction of the adjacent wall when it is opened and the door closer is then located between the door leaf and this wall, so there is a risk that the door closer will open too wide of the door leaf against the adjacent wall and is damaged, especially if the door is installed in a corner of the room or a thick-walled wall. In such applications, a limitation of the opening angle is appropriate. Therefore, compact door closers with the smallest possible build are desirable height while maintaining the previous variety of applications and the different functions.
- the external dimensions, in particular the overall height, of the known door closer are very high due to the special internal structure, so that a corresponding amount of packaging material is required for the packaging of the door closer and corresponding storage and transport space must also be available.
- the angular outer shape of the door closer creates manufacturing problems due to material cavities and is not optimal from the point of view of 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
- CONFIRMATION COPY optically appealing unit is created, which can be manufactured with minimal material and manufacturing costs.
- the subject matter of claim 1 has the advantage that a small overall height can be achieved due to the compact outer shape of the door closer.
- the door closer is therefore also suitable for use in tight 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 of which 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 visually appealing through flowing and seamless transitions.
- the body is elongated due to the row arrangement of the functional units, the side surfaces nestling against the contours of the channel. A curved or oblique course of the side surfaces is ideal.
- the side surfaces have block-like solid reinforcements, which in turn are designed to save material.
- the connection of these so-called bearing blocks to the underside of the body is particularly advantageous.
- the drive shaft is arranged so that different mounting positions of the door closer can be realized.
- the shaft is extremely material-saving and easy to assemble and fasten in the corresponding axle hole.
- the reduction in the external dimensions reduces the amount of packaging materials required and reduces the storage and transport space.
- the reduction in volume and weight increases the packing density during transport and also makes it easier for the assembly workers on site to handle it.
- the properties mentioned also contribute significantly to reducing manufacturing costs.

- the door closers 1 shown in the figures are made in one piece in a casting process and consist, for. B. made of aluminum or steel. Despite the aspect of optimizing the minimal use of materials with sufficient body stability, none is created solid body 2. Basically, all outer contours and surface transitions are rounded.
- the door closers 1 are each equipped to accommodate a mechanical and a hydraulic functional unit, which are arranged in a known manner in the longitudinal extent of the body 2 in a channel 21 to reduce the overall height.
- 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 out of the body 2, depending on the arrangement of the door closer 1 and linkage, based on a door leaf and a door frame to be able to handle the assembly conditions variably. For the sake of clarity, the linkage is not shown.
- a piston 23 and a closer spring 24 are slidably coupled to one another.
- the shaft 22 is rotatably mounted in the body 2 and has a gear wheel 25 in the center, which cooperates with a toothed rack 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 axis bore 27 for mounting and fastening the shaft 22.
- the axis bore 27 has a round cross section.
- the upper part of the axis bore 27 in FIG. 5 has a cross-sectional narrowing edge 28.
- the lower part of the axis bore 27 has a groove 29 for a sealing ring 30.
- the shaft 22 is symmetrical and has the gear 25 in the center.
- Disks 31 are preassembled on both sides of the gear wheel 25.
- At both ends of the shaft 22 are devices for attaching a rod.
- the linkage is installed at the appropriate end depending on the installation situation.
- So-called sintered bushings 32, 37 made of ceramic material serve as bearings on both sides of the shaft 22.
- a tubular bearing shell 33 has a stepped cross section, which ends in an edge 34. The outer surface of the bearing shell 33 is at least partially radially enlarged.
- the bearing shell 33 forms a preassembled unit, into which an annular seal 35 is first pushed against the edge 34 and then the sintered bush 32 is pressed against the annular seal 35 in a non-detachable manner.
- an annular seal 36 and then the sintered bush 37 are permanently fixed.
- the sealing ring 30 is inserted in the groove 29 of the lower part of the axle bore 27, the sealing ring 30 is inserted.
- the shaft 22 is inserted through the lower part of the axle bore 27.
- the shaft 22 slides within the upper part of the axle bores 27 through the sintered bush 37 fixed therein until it abuts the channel 21 with the disk 31.
- the complete mounting and fastening of the shaft 22 is carried out by inserting the bearing shell 33 in the lower part of the axle bore 27.
- the pre-assembled 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 region 2 enlarged bearing shell 33 preferably by means of a projection, elastically presses the body 2 surrounding the axle bore 27 outwards. After passing through the groove 29, the projection hooks into the groove 29 due to the springback of the body 2 and the bearing shell 33 is fastened.
- the shaft 22 is also positioned axially by the sintered bush 32 resting on the disk 31.
- the body 2 is basically elongated. It has an upper surface 3 opposite an underside 4.
- On the bottom 4 mounting plates 9, 10 are formed in the longitudinal extension, which for fastening the Serve body 2 on a door leaf or door frame.
- the underside 4 and the upper surface 3 are connected in the longitudinal direction by side surfaces 5, 6.
- End faces 7, 8 are arranged perpendicular to the side faces 5, 6 and to the underside 4 and the upper face 3 and delimit the body 2 in the longitudinal direction.
- the mounting plates 9, 10 protrude from the body 2 at the end faces 7, 8.
- the exemplary embodiment according to FIGS. 1-3 has the following peculiarities.
- the side surfaces 5, 6 start at the bottom 4 with a curvature directed towards the body and end at the surface 3.
- the curvature has a parabolic shape, the upper surface 3 delimiting this shape.
- 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 underside 4 and off-center between the end faces 7, 8.
- This arrangement of the shaft 22 enables diverse, for example mirror-image, mounting variants of the door closer 1. It emerges from the body 2 on bearing surfaces 11, 12 on bearing blocks 11, 12.
- the bearing blocks 11, 12 are solid and integrally formed on the body 2, to ensure stable shaft support.
- the bearing blocks 11, 12 each have trapezoidal front surfaces 13, 14 which run perpendicular to the underside 4, the broad base sides 15, 16 being on the underside 4. This trapezoidal cross section of the bearing blocks 11, 12 continues from the front surfaces 13, 14 to the side surfaces 5, 6 in a slightly enlarging manner.
- the bearing blocks 11, 12 are dimensioned so that they do not protrude above the upper surface 3.
- a body 2 is shown in FIGS. 6 and 7, the side faces 5, 6 of which also run parabolically.
- the upper surface 3 is curved slightly outward of the body, so that additional 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, the open sides 17, 18 on the underside 4.
