Description

Türschließer Door closer
Beschreibungdescription
Die Erfindung betrifft einen Türschließer gemäß dem Oberbegriff des Pa¬ tentanspruches 1.The invention relates to a door closer according to the preamble of claim 1.
Ein Universaltürschließer dieser Art ist aus der DE-AS 25 35 244 bekannt geworden. Innerhalb eines Gehäuses befindet sich ein Kraftspeicher in Form einer Druckfeder. Diese Druckfeder stützt sich einerends an einer Schwinge und einer damit verbundenen Rolle ab, wobei das andere Ende gegen einen Verschluß in der Außenwand des Gehäuses abgestützt ist. Innerhalb des Verschlusses befindet sich darüber hinaus eine Federkraft¬ verstellung, die von außen zugänglich ist. Über die Federkraftverstellung ist eine stufenlose Einstellung der Federkraft des Federspeichers zu reali¬ sieren. Wird die Antriebsachse des Türschließers aufgrund der ange¬ schlossenen Tür verdreht, so wird sich gleichzeitig aufgrund der mit der Antriebsachse kraft- und formschlüssig verbundenen Nockenscheibe eine Komprimierung der Druckfeder einstellen. Durch die Komprimierung der Druckfeder wird neben dem erhöhten Druck des Dämpfungsmediums ein weiterer zusätzlicher Druck auf den Verschlußdeckel des Gehäuses durch die Druckfeder ausgeübt.A universal door closer of this type has become known from DE-AS 25 35 244. An energy store in the form of a compression spring is located within a housing. This compression spring is supported at one end on a rocker arm and a roller connected to it, the other end being supported against a closure in the outer wall of the housing. There is also a spring force adjustment inside the closure, which is accessible from the outside. The spring force adjustment enables the spring force of the spring accumulator to be infinitely adjusted. If the drive axis of the door closer is rotated due to the connected door, compression of the compression spring will occur at the same time due to the cam disk which is connected to the drive axis in a non-positive and positive manner. As a result of the compression of the compression spring, in addition to the increased pressure of the damping medium, a further additional pressure is exerted on the sealing cover of the housing by the compression spring.
Ein weiterer Türschließer mit einstellbarer Schließkraft ist der DE-PS 32 24 300 zu entnehmen. Der Aufbau dieses Türschließers ist analog der DE-OS 25 35 244 zu sehen, ebenfalls liegt hier bei geöffneter Tür der gesamte Druck zusätzlich auf dem Abschlußdeckel des Türschließergehäuses. Die Federkraftverstellung wird durch eine von außen zugängliche, über ein Gewinde realisierte Verstellvorrichtung ermöglicht.Another door closer with adjustable closing force can be found in DE-PS 32 24 300. The structure of this door closer can be seen analogously to DE-OS 25 35 244, likewise, when the door is open, the entire pressure is additionally on the end cover of the door closer housing. The spring force adjustment is made possible by an adjustment device that is accessible from the outside and is implemented using a thread.
Eine weitere Verstellbarkeit der Federkraft ist auch in der Form möglich, daß diese nicht im montierten Zustand verändert werden kann, sondern gleich während der Montage entsprechend der Größe des Türschließers eingestellt werden muß. Dieses ist insbesondere der Patentliteratur DE-PS 10 36 711 , US 3,838,477, US 4,064.589 und AU 491 ,835 zu entnehmen. Die Druckfedern werden hier durch ein durch sie hindurchgehendes Füh- rungs- und Kraftübertragungselement bzw. Kraftabstützungselement ge¬ führt, wobei an einem Ende dieser Führungsmittels sich eine Versteilvor¬ richtung befindet, die es zuläßt, die Federkraft stufenlos einzustellen Der für den Schließvorgang der angeschlossenen Tür darüber hinaus notwen- dige Dämpfungskolben befindet sich neben den dargestellten Kraftspei¬ chern bzw. bei der US 4,064,589 als Zusatzelement angeflanscht außer¬ halb des Raumes, den die Druckfeder einnimmt.A further adjustability of the spring force is also possible in the form that it cannot be changed in the assembled state, but must be adjusted according to the size of the door closer during assembly. This can be found in particular in the patent literature DE-PS 10 36 711, US 3,838,477, US 4,064,589 and AU 491, 835. The compression springs are here guided by a guide guiding and power transmission element or power support element, an adjustment device being located at one end of this guide means, which allows the spring force to be adjusted continuously. The damping piston which is also required for the closing process of the connected door is located next to the ones shown Kraftspei¬ or in US 4,064,589 flanged as an additional element outside the space occupied by the compression spring.
In der GB 2,244,759 A wird ein Türschließer offenbart, bei dem eine Fe¬ derverstellung von außerhalb der Feder möglich ist. Dieses hat zur Folge, daß die Außenabmessungen des Türschließers größer werden, weil die Verstellhulse hinter der Feder des Türschließers liegt.GB 2,244,759 A discloses a door closer in which spring adjustment is possible from outside the spring. This has the consequence that the outer dimensions of the door closer become larger because the adjusting sleeve is behind the spring of the door closer.
Alle zum Stand der Technik zählenden Türschließer sind in ihren geome¬ trischen Abmaßen sehr groß, da die Dampfungseinπchtung nicht unmittel¬ bar mit der Druckfeder gekoppelt bzw verbunden ist. Ferner wird es auf- grund der gewählten Konstruktionsarten notwendig, daß das Gehäuse, insbesondere im Bereich der Verschlußkappen entsprechend überdimen¬ sioniert werden muß, um die großen auftretenden Kräfte sicher zu beherr¬ schenAll door closers belonging to the prior art are very large in their geometric dimensions, since the damping device is not directly coupled or connected to the compression spring. Furthermore, because of the types of construction chosen, it is necessary that the housing, in particular in the area of the sealing caps, be appropriately overdimensioned in order to reliably master the large forces that occur
Die Aufgabe der Erfindung ist es, einen Türschließer mit kleinen geometn- sehen Gehauseabmessungen, jedoch auch mit einem sehr hohen Wir¬ kungsgrad, zu schaffen, bei dem gleichzeitig die Schließkraft einstellbar ist, und die Druckverteilungen auf die Gehausewande reduziert und optimiert werdenThe object of the invention is to create a door closer with small geometn- see housing dimensions, but also with a very high efficiency, at the same time the closing force is adjustable, and the pressure distributions on the housing walls are reduced and optimized
Die Aufgabe der Erfindung wird dadurch gelöst, daß sich die Druckfeder innerhalb des Gehäuses zum einen abstützt und die Federkraftverstellung auf der anderen Seite das Gegenlager bildet Dabei liegt die Federkraft¬ verstellung innerhalb der Feder in einer Federstellhulse. die keine feste Verbindung, d h es liegt nur eine formschlussige Verbindung vor mit der außerhalb des Gehäuses liegenden Einstellvorπchtung hat Die Federver- Stellung liegt innerhalb des Druckraumes Die gesamte Versteilvorrichtung geht bei Öffnung des angeschlossenen Türflügels mit. d.h durch die ge¬ wählte Konstruktion, nämlich Kolben mit daπnhegender Druckfeder, wird der Kolben gezogen. Aufgrund des ausgeführten Kraftubertragungsele- mentes liegt beim Öffnen der Tür am Kolben eine Zugkraft an. Hierdurch ergibt sich eine gerade Führung des Kolbens, was eine Verkantung des Kolbens, der in relativ engem Abstand zur Antriebsachse mit der daran befindlichen Hubkurvenscheibe im Anschluß an die Druckfeder gelegt worden ist, vermeidet.The object of the invention is achieved in that the compression spring is supported on the one hand within the housing and the spring force adjustment on the other side forms the counter bearing. The spring force adjustment lies within the spring in a spring actuating sleeve. which has no fixed connection, ie there is only a positive connection with the adjustment device located outside the housing. The spring adjustment lies within the pressure chamber. The entire adjusting device moves with the opening of the connected door leaf. ie the piston is pulled by the selected construction, namely piston with a compression spring. Due to the power transmission element There is a tensile force on the piston when the door is opened. This results in a straight guidance of the piston, which avoids tilting of the piston, which has been placed at a relatively close distance from the drive axis with the cam disc located thereon following the compression spring.
Durch diese Anordnung ist die Druckverteilung der Druckfeder auf eng¬ stem Räume, nämlich zwischen die Antriebsachse und die Gehäuseab- stützung verlagert worden, was gleichzeitig bedeutet, daß auf die für den Einbau der Druckfeder notwendige Verschlußkappe, mit der darin befindli- chen Versteilvorrichtung, nicht die zusätzlichen hohen Drücke der Druck¬ feder auftreten, weil der Kraftangriff nach außen gelegt worden ist. und damit über die durch die Feder hindurchführenden Kraftübertragungsele¬ mente eine Zugbeanspruchung am Kolben, von der Antriebsachse aus gesehen, möglich ist. Dieses bedeutet ferner, daß keine zusätzlichen Ab- dichtungen der Verbindungsglieder zwischen der Hubkurvenscheibe mit ihrem Laschenwagen und andererseits mit der Federverstellung notwendig sind. Diese Art der Anordnung garantiert einen sehr hohen Wirkungsgrad, weil eine äußerst präzise Führung des Kolbens gegeben ist, und dadurch zusätzliche Reibungskräfte durch Verkanten vermieden werden.As a result of this arrangement, the pressure distribution of the compression spring has been shifted to the narrowest spaces, namely between the drive axle and the housing support, which means at the same time that the closure cap required for the installation of the compression spring, with the adjusting device located therein, has not the additional high pressures of the compression spring occur because the force application has been placed outside. and thus a tensile stress on the piston, as seen from the drive axis, is possible via the force transmission elements passing through the spring. This also means that no additional seals for the connecting links between the cam disc with its plate carriage and, on the other hand, with the spring adjustment are necessary. This type of arrangement guarantees a very high degree of efficiency, because the piston is guided with extreme precision, and additional frictional forces caused by tilting are avoided.
Die Federkraftverstellung wird dahingehend realisiert, daß eine Vorrichtung geschaffen worden ist. die durch eine Einstellhülse, die sich innerhalb des von der Druckfeder umgebenen Raumes befindet, umgesetzt wird. Diese Einstellhülse hat einen Hohlraum, in dessen Grund eine Verbindung zwi¬ schen den Kraftübertragungsgliedern, nämlich dem Laschenwagen und dem Verbindungsglied hergestellt wird. Über diese Verbindung wird die Federkraft gleichzeitig eingestellt, was zum einen für die Montage direkt im nicht eingebauten Zustand vorgenommen werden kann, bzw. im eingebau¬ ten Zustand derart realisiert wird, daß sich innerhalb der Federverstell¬ hülse ein Hohlraum befindet, in welchen eine in der Verschlußkappe gela- gerte Versteilvorrichtung eintaucht. Durch das komplette Eintauchen der VerStelleinrichtung in die Federverstellhülse, also in den Federinnenraum. wird eine enorme Reduzierung der Baulänge des Türschließers erreicht Die Kraftübertragung zwischen dem Mitnehmer der Versteilvorrichtung und der Einstellhülse wird durch Formschluß erreicht. Dieses kann beispiels- weise ein Sechskant oder auch jede andere geometrische Form sein, wo¬ bei insbesondere die Form des Mitnehmers entsprechend in den Durch¬ bruch der Einstellhulse eingearbeitet wird Dieses zeigt, daß keine feste Verbindung zwischen dem Einstellorgan, welches von außen zugänglich ist und der innerhalb des Druckraumes befindlichen Federkraftverstellung gegeben ist Gleichzeitig kann jedoch durch Betätigung der Emstellvorrich- tung von außen die Federkraft verändert werden, ohne hier eine Beein¬ trächtigung des Arbeitsablaufes des Türschließers herbeizufuhrenThe spring force adjustment is realized in that a device has been created. which is implemented by an adjusting sleeve, which is located within the space surrounded by the compression spring. This adjusting sleeve has a cavity, in the bottom of which a connection is established between the force transmission members, namely the plate carriage and the connecting member. Via this connection, the spring force is adjusted at the same time, which can be done for the assembly directly in the non-installed state, or realized in the installed state in such a way that there is a cavity within the spring adjustment sleeve, in which a cavity is located immersed in the locking cap. By completely immersing the adjustment device in the spring adjustment sleeve, i.e. in the spring interior. an enormous reduction in the overall length of the door closer is achieved. The power transmission between the driver of the adjusting device and the adjusting sleeve is achieved by positive locking. This can for example may be a hexagon or any other geometrical shape, the shape of the driver in particular being incorporated accordingly into the opening of the adjusting sleeve. This shows that there is no fixed connection between the adjusting member, which is accessible from the outside, and that inside the pressure chamber existing spring force adjustment is given. At the same time, however, the spring force can be changed from the outside by actuating the adjusting device without causing an impairment of the work sequence of the door closer
Die Erfindung wird anhand eines schematisch dargestellten möglichen Ausfuhrungsbeispieles naher erläutert Es zeigtThe invention is explained in more detail with reference to a possible exemplary embodiment shown schematically. It shows

Die Figur 2 zeigt in einer Schnittdarstellung von oben gesehen im wesent- liehen die Anordnung einer Druckfeder 1 eines Kolbens 19 und einer Hub- kurvenscheibe 17 innerhalb eines Gehäuses 18 Auf einer Antriebsachse 24 des Türschließers ist die Hubkurvenscheibe 17 kraft- und formschlussig angeordnet, die von einer Druckrolle 30 und einer Stutzrolle 28, die in einem Laschenwagen 31 befestigt sind, gefuhrt werden Gleichzeitig ist an dem Laschenwagen 31 auch der Kolben 19 befestigt Im Anschluß an den Kolben 19 ist ein Verbindungsglied 20 zur Aufnahme einer Verstell- schraube 23 vorhanden Dieses Verbindungsglied 20 taucht in den Innen¬ raum der Druckfeder 1 ein, und wird somit ganz von ihr umschlossen Die Druck-feder 1 ist innerhalb des Gehäuses 18 so plaziert daß sie sich etwa zur Gehausemitte an einem Vorsprung 21 mit einer dazwischen befindli¬ chen Stutzscheibe 4 einerends abstutzt, wobei das andere freie Ende ge¬ gen eine Stutzscheibe 6 gerichtet ist Durch die Stutzscheibe 6 ist eine Einstellhulse 2 hindurchgefuhrt, die ebenfalls in den Innenraum der Druck¬ feder 1 hineinragt Die Einstellhulse 2 ist so konstruiert daß sie einen vor- springenden Kragen 5 hat der sich an der Stutzscheibe 6 abstutzt Die Einstellhülse 2 ist weiter so ausgebildet, daß in ihrem inneren Bereich ein Hohlraum 8 vorhanden ist. Im Bereich des Kragens 5 ist ein Durch¬ bruch 11 , der eine entsprechend dem Mitnehmer 12 gestaltete geometri¬ sche Form zur formschlüssigen Verbindung zwischen dem Mitnehmer 12 und der Einstellhülse 2 möglich macht. Dabei taucht der Mitnehmer 12 ent¬ sprechend der Bewegungsrichtung 16 durch den Durchbruch 11 in den Hohlraum 8 der Einstellhülse 2 ein. Gleichzeitig wird aber auch der Mit¬ nehmer 12 von der Druckfeder 1 umgeben, so daß in dem Innenraum der Druckfeder 1 der Mitnehmer plaziert ist. Dieses bewirkt, daß keine Vergrö- ßerung des Türschließers durch den Verstellmechanismus gegeben ist. Der Durchbruch 11 ist von den geometrischen Abmaßen etwas kleiner ge¬ halten, so daß quasi der Mitnehmer 12 nur im Bereich des Durchbruches 11 eine formschlüssige Verbindung mit der Einstellhülse 2 eingeht.FIG. 2 shows, in a sectional view from above, essentially the arrangement of a compression spring 1 of a piston 19 and a cam cam 17 within a housing 18. The cam cam 17 is arranged on a drive axis 24 of the door closer in a non-positive and positive manner a pressure roller 30 and a support roller 28, which are fastened in a tab carriage 31, are simultaneously guided. The piston 19 is also attached to the tab carriage 31. Following the piston 19, a connecting member 20 for receiving an adjusting screw 23 is provided. This connecting member 20 plunges into the interior of the compression spring 1, and is thus completely enclosed by it. The compression spring 1 is placed inside the housing 18 in such a way that it is supported at one end by a protrusion 21 with a support disk 4 in between, approximately in the middle of the housing , wherein the other free end is directed towards a support disk 6 through the support disk 6 t an adjustment sleeve 2 passes through, which also projects into the interior of the compression spring 1. The adjustment sleeve 2 is constructed in such a way that it has a projecting collar 5 which is supported on the support disk 6 The adjusting sleeve 2 is further designed so that a cavity 8 is present in its inner region. In the area of the collar 5 there is a breakthrough 11, which enables a geometrical shape designed in accordance with the driver 12 for the positive connection between the driver 12 and the adjusting sleeve 2. The driver 12 plunges into the cavity 8 of the adjusting sleeve 2 through the opening 11 in accordance with the direction of movement 16. At the same time, however, the driver 12 is also surrounded by the compression spring 1, so that the driver is placed in the interior of the compression spring 1. This means that the adjustment mechanism does not enlarge the door closer. The opening 11 is kept somewhat smaller in terms of the geometric dimensions, so that the driver 12 virtually only enters into a positive connection with the adjusting sleeve 2 in the area of the opening 11.
Im Boden 9 der Einstellhülse 2 befindet sich ein Gewinde 10, welches zur Federkraftverstellung in Verbindung mit der Verstellschraube 23 durch Betätigung des Gewindes eine Federkraftverstellung herbeiführt. Dabei ist die Verstellschraube 23 vorzugsweise mit dem Verbindungsglied 20 in kraft- und formschlüssigem Eingriff. Ein Gegenlager und damit Anschlag zum unbeabsichtigten Herausdrehen der Federkraftverstellung 23 bildet die Sicherungsscheibe 22. Diese legt sich im entspannten Zustand der Federkraftverstellung gegen den Boden 9 der Einstellhülse 2. In Figur 3 wird deutlich gemacht, wie der Federverstellweg 32 zur Federverstellung und damit entsprechenden Krafteinstellung ausgenutzt werden kann. In diesem Ausführungsbeispiel ist der maximal mögliche Federeinstellweg 32 ausgenutzt worden.In the bottom 9 of the adjusting sleeve 2 there is a thread 10, which for spring force adjustment in connection with the adjusting screw 23 brings about a spring force adjustment by actuating the thread. The adjusting screw 23 is preferably in a non-positive and positive engagement with the connecting member 20. A counter bearing and thus a stop for unintentionally unscrewing the spring force adjustment 23 forms the locking washer 22. In the relaxed state of the spring force adjustment, it lies against the bottom 9 of the adjusting sleeve 2. In FIG. 3 it is made clear how the spring adjustment path 32 is used for spring adjustment and thus corresponding force adjustment can be. In this exemplary embodiment, the maximum possible spring adjustment path 32 has been used.
Durch die Betätigung der Antriebswelle 24 mit der daran nicht dargestellten angeschlossenen Tür wird ein Verschwenken der Hubkurvenscheibe 17 bewirkt. Gleichzeitig wird auch der Kolben 19 innerhalb der Zyliπderwan- dung 29 in die Betätigungsrichtung 27 seinen Hub ausüben.The actuation of the drive shaft 24 with the connected door (not shown) causes the cam disc 17 to pivot. At the same time, the piston 19 will also exert its stroke within the cylinder wall 29 in the actuation direction 27.
Um die Federkraftverstellung auch im eingebauten Zustand verändern zu können, ist der Mitnehmer 12 innerhalb der Verschlußkappe 3 über eine Dichtung 25 und zur Sicherung über eine Sicherungsscheibe 26 plaziert. Das aus der Verschlußkappe 3 herausragende Ende des Mitnehmers 12. nämlich die Verstellschraube 13 ist mit einem entsprechenden Werkzeug zugänglich. Die Verschlußkappe 3 wird über ein Gewinde 14 in das Ge¬ häuse 18 eingeschraubt. Eine Abdichtung wird durch die Dichtung 15 er¬ reicht. Beim Einsetzen der Verschlußkappe 3 wird gleichzeitig der vorste- hende Mitnehmer 12 in die Einstellhülse durch den Durchbruch 11 hin¬ durch so eingeführt, daß keinerlei über den Mitnehmerquerschnitt hinaus¬ gehende Vergrößerungen vorhanden sind. Der Mitnehmer 12 ist vollstän¬ dig im Inneren der Einstellhülse 2 untergebracht. Im Ausführungsbeispiel ist der Mitnehmer 12 mit einem Sechskant versehen, was bedeutet, daß auch in dem Durchbruch 11 die gleiche Form des Seehskantes vorhanden ist. Es ist jedoch auch denkbar, hier jede andere Form einzusetzen, die in der Lage ist, die entsprechenden Kräfte zur Verstellung der Druckfeder 1 bei Betätigung der Verstellschraube 13 zu übertragen.In order to be able to change the spring force adjustment even in the installed state, the driver 12 is placed inside the closure cap 3 via a seal 25 and for securing purposes via a locking washer 26. The end of the driver 12 protruding from the sealing cap 3. namely the adjusting screw 13 is accessible with an appropriate tool. The closure cap 3 is screwed into the housing 18 via a thread 14. A seal is achieved by the seal 15. When the closure cap 3 is inserted, the protruding driver 12 is simultaneously introduced into the adjusting sleeve through the opening 11 in such a way that there are no enlargements beyond the driver cross section. The driver 12 is completely housed inside the adjusting sleeve 2. In the exemplary embodiment, the driver 12 is provided with a hexagon, which means that the same shape of the sea edge is also present in the opening 11. However, it is also conceivable to use any other form which is capable of transmitting the corresponding forces for adjusting the compression spring 1 when the adjusting screw 13 is actuated.
In dem Ausführungsbeispiel der Figur 2 ist die Druckfeder 1 im entkom- primierten Zustand dargestellt. Gleichzeitig wird deutlich, daß der Mitneh¬ mer 12 innerhalb der Einstellhülse 2 in den Hohlraum 8 komplett einge¬ taucht ist, im Gegensatz zum Stand der Technik, bei dem die Mitnehmer hinter der Verstellvorrichtung liegen und somit eine Verlängerung des Tür¬ schließers zur Folge haben. Im Gegensatz dazu ist in der Figur 3 die Druckfeder 1 mit maximaler Federvorspannung eingestellt und gleichzeitig die Tür um 180° verschwenkt worden, was eine maximale Komprimierung der Druckfeder 1 zur Folge hat. In dieser Extremstellung muß noch sicher¬ gestellt werden, daß der Mitnehmer 12 auch weiterhin in den Durchbruch 11 der Einstellhülse 2 eintaucht. Durch diese Art der Vorrichtung wird klar, daß keine feste Verbindung zwischen der Federverstellung und dem Ver¬ bindungsglied 20 vorliegt. Die gesamte Verstellschraube 23 wird bei Betä¬ tigung der Antriebsachse 24 mit bewegt, d.h. sie wird gezogen, was gleichzeitig eine bessere Führung für den Kolben 19 (Dämpfungseinπch- tung) darstellt Durch diese Art der Konstruktion wird deutlich, daß zusatz- liehe Druckkräfte auf die Verschlußkappe 3 nicht ausgeübt werden wie es beim bekannten Stand der Technik der Fall ist. Die gesamte Druckvertei¬ lung ist auf einen sehr engen Raum ausgerichtet worden, nämlich etwa zur Mitte des Gehäuses hin. Durch diese Art der Konstruktion wird es möglich, die geometrischen Abmaße des Gehäuses in sehr engen Grenzen zu hal- ten Auch ist keine zusätzliche Abdichtung einer sonst normalerweise vor- handenen Kolbenstange notwendig, da beim erfindungsgemäßen Gegen¬ stand die gesamte Vorrichtung der Federverstelleinrichtung sich innerhalb des Druckraumes befindet. Durch diese Maßnahme wird der Wirkungsgrad eines solchen Türschließers wesentlich höher liegen als bei den bisher zum Stand der Technik zählenden Türschließern. Weitere Vorteile der Er¬ findung sind eine wesentlich geringere Baulänge des Türschließers bei gleichzeitig geringeren Abmaßen des Gehäuses. Eine Einstellung der Fe¬ derkraft ist problemlos durchzuführen, wobei gleichzeitig auch sicherge¬ stellt ist, daß eine Verdrehung des Kolbens und damit möglicherweise Ver- kantung und Herabsetzung des gewünschten Wirkungsgrades nicht gege¬ ben ist. In the exemplary embodiment in FIG. 2, the compression spring 1 is shown in the decompressed state. At the same time it becomes clear that the driver 12 is completely immersed into the cavity 8 within the adjusting sleeve 2, in contrast to the prior art, in which the drivers are behind the adjusting device and thus result in an extension of the door closer . In contrast to this, in FIG. 3 the compression spring 1 has been set with maximum spring preload and at the same time the door has been pivoted through 180 °, which results in maximum compression of the compression spring 1. In this extreme position, it must also be ensured that the driver 12 continues to immerse in the opening 11 of the adjusting sleeve 2. This type of device makes it clear that there is no fixed connection between the spring adjustment and the connecting member 20. The entire adjusting screw 23 is also moved when the drive shaft 24 is actuated, ie it is pulled, which at the same time represents better guidance for the piston 19 (damping device). This type of construction makes it clear that additional compressive forces act on the Cap 3 are not exercised as is the case with the known prior art. The entire pressure distribution has been aligned to a very narrow space, namely towards the middle of the housing. This type of construction makes it possible to keep the geometrical dimensions of the housing within very narrow limits. There is also no additional sealing of an otherwise normally existing piston rod necessary, since the entire device of the spring adjustment device is located within the pressure chamber in the subject invention. As a result of this measure, the efficiency of such a door closer will be considerably higher than that of the door closers which have hitherto been state of the art. Further advantages of the invention are a substantially shorter overall length of the door closer with simultaneously smaller dimensions of the housing. Adjustment of the spring force can be carried out without any problems, and at the same time it is also ensured that the piston is not twisted and thus possibly tilted and the desired efficiency is not reduced.
