Description

Die Erfindung betrifft eine Dämpfungseinrichtung für Möbeltüren mit einem in einer Ausnehmung eines Dämpfergehäuses längsverschieblich aufgenommenen Dämpfungszylinder, der ein Zylindergehäuse und eine Kolbenstange aufweist und einen Anschlag für die Möbeltür bildet und mittels einer Stellschraube an dem dem Anschlag abgekehrten hinteren Ende der Ausnehmung längsverstellbar ist.The invention relates to a damping device for furniture doors with a longitudinally displaceably received in a recess of a damper housing damping cylinder, which has a cylinder housing and a piston rod and forms a stop for the furniture door and is longitudinally adjustable by means of a screw on the stop facing away from the rear end of the recess.

Dämpfungseinrichtungen für Möbeltüren sind in unterschiedlichen Ausführungsformen bekannt. Die Möbeltür trifft am Ende ihrer Schließbewegung auf die Dämpfungseinrichtung und wird bis zum vollständigen Schließen abgebremst, so dass ein unerwünschtes schlagartiges Auftreffen der Möbeltür auf den Möbelkorpus oder auf den Frontrahmen verhindert wird.Damping devices for furniture doors are known in different embodiments. The furniture door meets at the end of its closing movement on the damping device and is slowed down until fully closed, so that an undesirable sudden impact of the furniture door on the furniture body or on the front frame is prevented.

In vielen Fällen ist die Dämpfungseinrichtung mit einem Möbelscharnier verbunden ( EP 1 538 293 B1 ). Das Dämpfergehäuse kann einteilig mit einem Teil des Möbelscharniers ausgeführt sein oder an diesem befestigt sein.In many cases, the damping device is connected to a furniture hinge ( EP 1 538 293 B1 ). The damper housing may be integral with or attached to a portion of the furniture hinge.

Bei einer bekannten Dämpfungseinrichtung der eingangs genannten Gattung ( DE 20 200 798 U1 ) ist das Zylindergehäuse des Dämpfungszylinders vollständig in der Ausnehmung des Dämpfergehäuses angeordnet, die dort als eine zur Möbelseite hin offene Ausnehmung ausgeführt ist. Die aus dem Dämpfergehäuse herausragende Kolbenstange bildet den Anschlag für die Möbeltür. Das Zylindergehäuse des Dämpfungszylinders ist zur Möbeltür hin über eine Druckfeder am Dämpfergehäuse abgestützt. Am entgegengesetzten Ende ragt die Stellschraube in die Ausnehmung des Dämpfergehäuses und bildet dort einen Anschlag, gegen den das Zylindergehäuse durch die Druckfeder gedrückt wird. Bei einer Verstellung der Stellschraube wird die Kolbenstange im Ausgangszustand unterschiedlich weit aus dem Dämpfergehäuse heraus bewegt, so dass der Dämpferweg verändert wird.In a known damping device of the aforementioned type ( DE 20 200 798 U1 ), the cylinder housing of the damping cylinder is arranged completely in the recess of the damper housing, which is designed there as a furniture side open towards recess. The protruding from the damper housing piston rod forms the stop for the furniture door. The cylinder housing of the damping cylinder is supported towards the furniture door via a compression spring on the damper housing. At the opposite end of the screw protrudes into the recess of the damper housing, where it forms a stop against which the cylinder housing is pressed by the compression spring. During an adjustment of the adjusting screw, the piston rod is moved out of the damper housing at different levels in the initial state, so that the damper travel is changed.

Da die Kolbenstange verhältnismäßig dünn ist, besteht die Gefahr einer Beschädigung, insbesondere wenn die von der Möbeltür ausgeübte Kraft nicht genau in axialer Richtung des Dämpfungszylinders verläuft. Die erforderliche Druckfeder stellt ein zusätzliches Bauteil dar, durch das sich der konstruktive Aufwand und die Störanfälligkeit erhöhen.Since the piston rod is relatively thin, there is a risk of damage, especially if the force exerted by the furniture door does not run exactly in the axial direction of the damping cylinder. The required compression spring is an additional component, through which increase the design complexity and susceptibility.

Aufgabe der Erfindung ist es daher, eine Dämpfungseinrichtung der eingangs genannten Gattung so auszugestalten, dass bei einfachem Aufbau eine besonders geringe Störanfälligkeit gegeben ist und die Einstellung in besonders einfacher Weise ermöglicht wird.The object of the invention is therefore to provide a damping device of the type mentioned in such a way that with a simple structure, a particularly low susceptibility is given and the adjustment is made possible in a particularly simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Zylindergehäuse in der als Bohrung ausgeführten Ausnehmung des Dämpfergehäuses längsverschieblich aufgenommen ist und mit seinem aus dem Dämpfergehäuse herausragenden Ende den Anschlag für die Möbeltür bildet, dass die Kolbenstange mit der Stellschraube verbunden ist und dass der Innendurchmesser eines die Stellschraube aufnehmenden Innengewindes mindestens gleich dem Innendurchmesser der das Zylindergehäuse aufnehmenden Bohrung ist.This object is achieved in that the cylinder housing is received longitudinally displaceable in the recess designed as a bore of the damper housing and forms with its protruding from the damper housing end the stop for the furniture door, that the piston rod is connected to the screw and that Inner diameter of the adjusting screw receiving internal thread is at least equal to the inner diameter of the cylinder housing receiving bore.

Die Verwendung des Zylindergehäuses als Anschlag für die Möbeltür und die Ausführung der das Zylindergehäuse aufnehmenden Ausnehmung als Bohrung bewirken eine erhöhte Stabilität der Dämpfungseinrichtung, bei der auch zusätzliche, auf den Anschlag wirkende Querkräfte nicht zu einer Beschädigung oder einem Verkanten führen. Durch die Verbindung der Kolbenstange mit der Stellschraube wird verhindert, dass sich der Dämpfungszylinder völlig aus der Bohrung des Dämpfungsgehäuses herausbewegen kann.The use of the cylinder housing as a stop for the furniture door and the execution of the cylinder housing receiving recess as a bore cause increased stability of the damping device, in which additional, acting on the stop lateral forces do not lead to damage or jamming. By connecting the piston rod with the adjusting screw prevents the damping cylinder can move completely out of the bore of the damping housing.

Da der Innendurchmesser des Innengewindes, in das die Stellschraube eingeschraubt wird, gleich oder größer als der Bohrungsdurchmesser ist, kann der Dämpfungszylinder zur Montage durch das Innengewinde hindurch in die Bohrung des Dämpfergehäuses eingeführt werden. Die Festlegung erfolgt nur durch das Einschrauben der Stellschraube in das Innengewinde. Zusätzlich einzusetzende Bauteile, wie eine Druckfeder, sind nicht erforderlich. Auch wenn die Dämpfungseinrichtung noch nicht am Möbelkorpus befestigt ist, besteht keine Gefahr, dass Teile davon herausfallen und verloren gehen. Die Montage der Dämpfungseinrichtung ist daher sehr einfach.Since the inner diameter of the internal thread into which the adjusting screw is screwed is equal to or larger than the bore diameter, the damping cylinder can be inserted through the female thread into the bore of the damper housing for mounting. The determination is made only by screwing the screw into the internal thread. Additional components to be used, such as a compression spring, are not required. Even if the damping device is not attached to the furniture body, there is no danger that parts of it fall out and get lost. The assembly of the damping device is therefore very simple.

Da die Stellschraube in das konzentrisch zur Bohrung verlaufende Innengewinde am Bohrungsende längsverstellbar eingeschraubt ist, erfolgt die Dämpfungseinstellung in einfacher Weise dadurch, dass die Stellschraube gedreht und somit mehr oder weniger tief in das Innengewinde eingeschraubt wird.Since the screw is screwed longitudinally adjustable in the concentric to the bore extending internal thread at the bore end, the damping adjustment is carried out in a simple manner in that the screw is rotated and thus more or less deeply screwed into the internal thread.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das Ende der Kolbenstange in einer zentrischen Bohrung der Stellschraube aufgenommen ist. Zweckmäßigerweise ist das Ende der Kolbenstange in der zentrischen Bohrung der Stellschraube verpresst. Damit wird in fertigungstechnisch einfacher Weise eine zuverlässige Verbindung der Stellschraube mit der Kolbenstange erreicht.According to a preferred embodiment of the invention it is provided that the end of the piston rod is received in a central bore of the screw. Appropriately, the end of the piston rod is pressed in the central bore of the screw. In order to achieve a reliable connection of the screw with the piston rod in manufacturing technology simple manner.

Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass zwischen der Kolbenstange und dem Dämpfergehäuse eine Druckfeder geschaltet ist. Die Druckfeder liegt somit im Kraftfluss zwischen dem von der Tür beaufschlagten Dämpfungszylinder und dem am Möbelkorpus abgestützten Dämpfergehäuse. Da die Dämpfungskraft geschwindigkeitsabhängig ist, tritt bei schlagartiger Beanspruchung, d. h. wenn die zu dämpfende Möbeltür mit hoher Geschwindigkeit zuschlägt, eine hohe Kraftspitze auf, die zur Beschädigung der Dämpfungseinrichtung führen kann, insbesondere der Befestigung des Dämpfergehäuses am Möbelkorpus.According to a particularly advantageous embodiment of the invention, it is provided that a compression spring is connected between the piston rod and the damper housing. The compression spring is thus in the power flow between the acted upon by the door damping cylinder and supported on the furniture body damper housing. Since the damping force is speed-dependent, occurs at sudden stress, d. H. If the furniture door to be damped strikes at high speed, a high force peak, which can damage the damping device, in particular the attachment of the damper housing to the furniture body.

Die in den Kraftfluss der Dämpfungskraft in Reihe mit dem Dämpfungszylinder geschaltete Druckfeder nimmt in einem solchen Fall die auftretende Kraftspitze auf; der Kraftverlauf wird abgeflacht, solange eine Verformungsweg der Druckfeder zur Verfügung steht.The pressure spring connected in series with the damping cylinder in the force flow of the damping force absorbs the force peak occurring in such a case; the force curve is flattened, as long as a deformation of the compression spring is available.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Druckfeder in einer Innenbohrung der Stellschraube zwischen einem an der Kolbenstange festgelegten, in der Innenbohrung längsverschiebbaren Druckkörper und einem in der Stellschraube festliegenden Federanschlag angeordnet ist. Damit ergibt sich eine sehr platzsparende Anordnung der Druckfeder, die zudem gegen Beschädigungen und Verunreinigungen geschützt ist.According to a preferred embodiment of the invention it is provided that the compression spring in an inner bore of Adjusting screw between a fixed to the piston rod, longitudinally displaceable in the inner bore pressure body and a fixed in the screw spring stop is arranged. This results in a very space-saving arrangement of the compression spring, which is also protected against damage and contamination.

Die in der Zeichnung dargestellte Dämpfungseinrichtung 1 ist an einem Frontrahmen 2 eines Möbelstücks angebracht, das in der sog. "Face-Frame-Bauweise" ausgeführt ist. Am Frontrahmen 2 ist über mindestens zwei Möbelscharniere 3, die in den Fig. 1 und 2 nur teilweise gezeigt sind, eine Möbeltür 4 angelenkt. Die Dämpfungseinrichtung 1 dient dazu, die Schließbewegung der Möbeltür 4 zu dämpfen.The damping device 1 shown in the drawing is attached to a front frame 2 of a piece of furniture, which is executed in the so-called. "Face-frame construction". On the front frame 2 is at least two furniture hinges 3, in the Fig. 1 and 2 only partially shown, hinged a furniture door 4. The damping device 1 serves to dampen the closing movement of the furniture door 4.

Die Dämpfungseinrichtung 1 weist ein Dämpfergehäuse 5 auf, das am Frontrahmen 2 angebracht ist. Das Dämpfergehäuse 5 kann ein gesondertes Bauteil bilden, wie in der Zeichnung dargestellt. Es kann aber auch als Teil des Möbelscharniers 3 ausgeführt sein.The damping device 1 has a damper housing 5, which is attached to the front frame 2. The damper housing 5 may form a separate component, as shown in the drawing. It can also be designed as part of the furniture hinge 3.

Eine Bohrung 6 im Dämpfergehäuse 5 bildet eine Ausnehmung, in der ein Dämpferzylinder 7 aufgenommen ist. Der Dämpferzylinder 7 weist ein Zylindergehäuse 8 und eine mit dem (nicht dargestellten) Dämpferkolben verbundene Kolbenstange 9 auf. Das Zylindergehäuse 8 bildet mit seinem aus dem Dämpfergehäuse 5 herausragenden Ende 8a einen Anschlag 10 für die Möbeltür 4. Zweckmäßigerweise ist am Anschlag 10 ein Puffer angebracht, der beim Schließen der Möbeltür 4 auf eine Metallfläche des Türbeschlagteils des Möbelscharniers 3 trifft.A bore 6 in the damper housing 5 forms a recess in which a damper cylinder 7 is received. The damper cylinder 7 has a cylinder housing 8 and a piston rod 9 connected to the damper piston (not shown). The cylinder housing 8 forms with its protruding from the damper housing 5 end 8a a stop 10 for the furniture door 4. Conveniently, a buffer is attached to the stop 10, which strikes when closing the furniture door 4 on a metal surface of the door fitting part of the furniture hinge 3.

Das Zylindergehäuse 8 ist in der Bohrung 6 des Dämpfergehäuses 5 längsverschieblich aufgenommen. Die Kolbenstange 9 ist an ihrem Ende mit einer Stellschraube 11 verbunden. Bei dem dargestellten Ausführungsbeispiel ist das Ende der Kolbenstange 9 in einer zentrischen Bohrung 12 der Stellschraube 11 aufgenommen. Die Verbindung der Kolbenstange 9 mit der Stellschraube 11 ist durch Verpressen erzeugt. Statt dessen kann das Ende der Kolbenstange 9 auch längsverschieblich in der Bohrung 12 aufgenommen sein, die als Sackbohrung ausgeführt ist.The cylinder housing 8 is received in the bore 6 of the damper housing 5 longitudinally displaceable. The piston rod 9 is at its end with a screw 11th connected. In the illustrated embodiment, the end of the piston rod 9 is received in a central bore 12 of the screw 11. The connection of the piston rod 9 with the screw 11 is produced by compression. Instead, the end of the piston rod 9 may also be accommodated longitudinally displaceable in the bore 12, which is designed as a blind bore.

Die Stellschraube 11 ist in ein Innengewinde 13 eingeschraubt, das konzentrisch zur Achse der Bohrung 6 im Dämpfergehäuse 5 ausgeführt ist. Der Innendurchmesser des Innengewindes 13 ist mindestens gleich, vorzugsweise aber - wie in der Zeichnung dargestellt - größer als der Innendurchmesser der das Zylindergehäuse 8 aufnehmenden Bohrung 6.The adjusting screw 11 is screwed into an internal thread 13, which is designed concentrically to the axis of the bore 6 in the damper housing 5. The inner diameter of the internal thread 13 is at least equal, but preferably - as shown in the drawing - larger than the inner diameter of the cylinder housing 8 receiving bore. 6

Die Stellschraube 11 weist einen aus dem Dämpfergehäuse 5 herausragenden Griffabschnitt 14 auf, der mit einer Rändelung 15 oder einer anderen, das Ergreifen der Stellschraube 11 erleichternden Kontur ausgeführt ist.The adjusting screw 11 has a protruding from the damper housing 5 handle portion 14 which is executed with a knurling 15 or another, the gripping of the screw 11 facilitating contour.

Beim dargestellten Ausführungsbeispiel weist die Bohrung 6 im Dämpfergehäuse 5 eine Durchbrechung 16 zu der Außenseite auf, die am Frontrahmen 2 anliegt.In the illustrated embodiment, the bore 6 in the damper housing 5 has an opening 16 to the outside, which bears against the front frame 2.

Zur Montage wird der Dämpfungszylinder mit der an der Kolbenstange 9 befestigten Stellschraube 11 in die Bohrung 6 eingeführt, wie in Fig. 3 dargestellt ist. Nach dem Einschrauben der Stellschraube 11 in das Innengewinde 13 ist die Dämpfungseinrichtung fertig montiert.For mounting the damping cylinder is inserted with the attached to the piston rod 9 screw 11 into the bore 6, as in Fig. 3 is shown. After screwing the screw 11 into the internal thread 13, the damping device is fully assembled.

Eine Verstellung der Dämpfungswirkung wird durch Verdrehen der Stellschraube 11 erreicht. Wie in Fig. 2 mit einem Doppelpfeil angedeutet, wird dadurch der gesamte Dämpfungszylinder 7 in Längsrichtung verstellt, so dass die Winkelstellung verändert wird, in der die Möbeltür 4 auf den Dämpfungszylinder 7 trifft (Fig. 1). Ausgehend von dieser Stellung wird bei der weiteren Schwenkbewegung der Möbeltür 4 das Zylindergehäuse 8 des Dämpfungszylinders 7 gegen die in dieser Stellung festgelegte Kolbenstange 9 und damit gegen den Dämpfungskolben im Inneren des Dämpfungszylinders 8 bewegt. Dadurch wird die Möbeltür 4 bei ihrer Schwenkbewegung zwischen den Stellungen gemäß Fig. 1 und Fig. 2 gedämpft.An adjustment of the damping effect is achieved by turning the screw 11. As in Fig. 2 indicated by a double arrow, thereby the entire damping cylinder 7 is adjusted in the longitudinal direction, so that the angular position is changed, in which the furniture door 4 meets the damping cylinder 7 ( Fig. 1 ). Starting from this position, the cylinder housing 8 of the damping cylinder 7 is moved against the fixed in this position piston rod 9 and thus against the damping piston in the interior of the damping cylinder 8 in the further pivotal movement of the furniture door 4. As a result, the furniture door 4 is in accordance with their pivotal movement between the positions Fig. 1 and Fig. 2 attenuated.

Die Abstützung der dabei auftretenden Dämpfungskraft erfolgt durch eine türseitige Abwinklung 17 des Dämpfergehäuses 5, die sich an der Frontfläche des Frontrahmens 2 abstützt. Weitere Maßnahmen zur Festlegung des Dämpfergehäuses 5 am Frontrahmen 2 durch Anschrauben oder in anderer Weise sind vorgesehen, jedoch in der Zeichnung nicht dargestellt.The support of the occurring damping force is effected by a door-side bend 17 of the damper housing 5, which is supported on the front surface of the front frame 2. Further measures for fixing the damper housing 5 on the front frame 2 by screwing or otherwise provided, but not shown in the drawing.

Die Dämpfungseinrichtung 1 kann in entsprechender Weise auch an der Stirnkante eines Möbelkorpus angebracht werden.The damping device 1 can be mounted in a corresponding manner also on the front edge of a furniture body.

Die in den Fig. 4-7 dargestellten Ausführungsbeispiele unterscheiden sich von den vorher beschriebenen Ausführungsbeispielen im Wesentlichen dadurch, dass zwischen der Kolbenstange 9 und dem Dämpfergehäuse 5 eine Druckfeder 18 in Reihe mit dem Dämpfungszylinder 8 geschaltet ist.The in the Fig. 4-7 illustrated embodiments differ from the previously described embodiments essentially in that between the piston rod 9 and the damper housing 5, a compression spring 18 is connected in series with the damping cylinder 8.

Die Druckfeder 18 befindet sich in einer Innenbohrung 19 der Stellschraube 11'. Die Druckfeder 18 ist zwischen einem Druckkörper 20 und einem in der Stellschraube 11' festliegenden Federanschlag 21 mit Vorspannung aufgenommen.The compression spring 18 is located in an inner bore 19 of the adjusting screw 11 '. The compression spring 18 is received between a pressure body 20 and a set in the screw 11 'fixed spring stop 21 with bias.

Der in der Innenbohrung 19 längsverschiebbare Druckkörper 20 ist mit der Kolbenstange 9 fest verbunden, die in dem Druckkörper 20 endet. Der Druckkörper 20 liegt in seiner in Fig. 4 dargestellten Ausgangsstellung an einem Anschlag 22 der Stellschraube 11' an, der von einem am Ende der Innenbohrung 19 radial nach innen vorspringenden Rand gebildet wird. Der Federanschlag 21 wird bei der Ausführung nach Fig. 4 durch einen in der Stellschraube 11' angebrachten Querstift gebildet.The longitudinally displaceable in the inner bore 19 pressure body 20 is fixedly connected to the piston rod 9, which ends in the pressure body 20. The pressure hull 20 lies in its in Fig. 4 illustrated starting position on a stop 22 of the adjusting screw 11 ', which is formed by a at the end of the inner bore 19 radially inwardly projecting edge. The spring stop 21 is in the execution after Fig. 4 formed by a in the screw 11 'mounted transverse pin.

Wenn die Möbeltür 4 mit hoher Geschwindigkeit schlagartig auf den Dämpfungszylinder 8 trifft, ist die geschwindigkeitsabhängige Dämpferkraft sehr hoch. Die schlagartig wirkende Kraft wird nahezu ungemildert auf die Kolbenstange 9 übertragen, deren Ende im Druckkörper 20 festgelegt ist. Unter der hierbei auftretenden Kraftspitze weicht der Druckkörper 20 unter Verformung der Druckfeder 18 aus. Dadurch wird die Druckspitze wesentlich abgeschwächt, bevor der Druckkörper 20 durch Verformung der Druckfeder 18 auf Block in der Stellschraube 11' zum Stillstand kommt. Damit wird verhindert, dass die anfängliche Druckspitze unvermindert auf das Dämpfergehäuse 5 und dessen Befestigung am Frontrahmen 2 des Möbelkorpus wirkt.When the furniture door 4 hits the damping cylinder 8 abruptly at high speed, the speed-dependent damper force is very high. The abruptly acting force is transmitted almost unmitigated to the piston rod 9, the end of which is fixed in the pressure body 20. Under the force peak occurring in this case, the pressure body 20 deviates under deformation of the compression spring 18. As a result, the pressure peak is significantly attenuated before the pressure body 20 by deformation of the compression spring 18 to block in the screw 11 'comes to a standstill. This prevents the initial pressure peak from acting undiminished on the damper housing 5 and its attachment to the front frame 2 of the furniture body.

Das in Fig. 5 in einem Teilschnitt dargestellte Ausführungsbeispiel unterscheidet sich von der Ausführung nach Fig. 4 im Wesentlichen dadurch, dass die Kolbenstange 9 an dem dem Dämpfungszylinder 8 abgekehrten Ende der Stellschraube 11' (rechts in Fig. 5) aus einer Endbohrung 23 der Stellschraube 11' herausragt und einen sich radial erstreckenden Haltevorsprung aufweist, der bei dem dargestellten Ausführungsbeispiel ein in einer Umfangsnut 24 der Kolbenstange 9 aufgenommener Sprengring 25 ist.This in Fig. 5 in a partial section embodiment differs from the embodiment to Fig. 4 essentially in that the piston rod 9 on the end facing away from the damping cylinder 8 of the adjusting screw 11 '(right in Fig. 5 ) protrudes from an end bore 23 of the adjusting screw 11 'and has a radially extending retaining projection, which is in the illustrated embodiment, a recorded in a circumferential groove 24 of the piston rod 9 snap ring 25.

Der Druckkörper 20, der in der Innenbohrung 19 gegen die Kraft der Druckfeder 18 verschiebbar aufgenommen ist, ist an einem Sprengring 26 abgestützt, der in einer Umfangsnut 27 der Kolbenstange 9 aufgenommen ist.The pressure body 20, which is slidably received in the inner bore 19 against the force of the compression spring 18 is supported on a snap ring 26 which is received in a circumferential groove 27 of the piston rod 9.

Wenn die von der Kolbenstange 9 ausgeübte Dämpfungskraft höher als die Vorspannung der Druckfeder 18 ist, verschiebt die Kolbenstange 9 über den Sprengring 26 den Druckkörper 20 gegen die Druckfeder 18, wobei sich das Ende der Kolbenstange 9 aus der Endbohrung 23 heraus bewegt.When the force exerted by the piston rod 9 damping force is higher than the bias of the compression spring 18, the piston rod 9 moves over the snap ring 26, the pressure body 20 against the compression spring 18, wherein the end of the piston rod 9 moves out of the end bore 23.

Bei der Ausführung der Dämpfungseinrichtung nach Fig. 6 endet die Kolbenstange 9 im Druckkörper 20. Der Druckkörper 20 weist auf seiner dem Dämpfungszylinder 8 abgekehrten Seite (rechts in Fig. 6) einen zentrischen Gleitzapfen 28 auf, der aus der Endbohrung 23 der Stellschraube 11' herausragt und in einer Umfangsnut 29 einen Sprengring 30 trägt.In the execution of the damping device according to Fig. 6 ends the piston rod 9 in the pressure body 20. The pressure body 20 has on its side facing away from the damping cylinder 8 (right in Fig. 6 ) on a central sliding peg 28 which protrudes from the end bore 23 of the screw 11 'and in a circumferential groove 29 carries a snap ring 30.

Bei der in Fig. 7 gezeigten Ausführung besteht das Dämpfergehäuse 5 aus einem Gehäuseaußenteil 31, das am Frontrahmen 2 festgelegt ist, und einem darin längsverschieblichen Gehäuseinnenteil 32, das in seiner Bohrung 6 das Zylindergehäuse 8 längsverschieblich aufnimmt.At the in Fig. 7 As shown, the damper housing 5 consists of an outer housing part 31, which is fixed to the front frame 2, and a longitudinally displaceable therein housing inner part 32, in its Bore 6, the cylinder housing 8 receives longitudinally displaceable.

Eine Druckfeder 33 ist zwischen dem Gehäuseaußenteil 31 und dem Gehäuseinnenteil 32 angeordnet und umgibt das Gehäuseinnenteil 32 konzentrisch. Die Druckfeder 33 ist mit Vorspannung zwischen einem äußeren Bund 34 des Gehäuseinnenteils 32 und einem nach innen vorspringenden Bund 35 des Gehäuseaußenteils 31 unter Vorspannung aufgenommen. Ein Sprengring 36, der in einer Umfangsnut 37 des Gehäuseinnenteils aufgenommen ist, stützt das längsbewegliche Gehäuseinnenteil 32 gegen die Kraft der Druckfeder 33 stirnseitig am Gehäuseaußenteil 31 ab.A compression spring 33 is arranged between the housing outer part 31 and the housing inner part 32 and surrounds the housing inner part 32 concentrically. The compression spring 33 is biased between an outer collar 34 of the housing inner part 32 and an inwardly projecting collar 35 of the housing outer part 31 received under bias. A snap ring 36 which is received in a circumferential groove 37 of the housing inner part, supports the longitudinally movable housing inner part 32 against the force of the compression spring 33 frontally on the housing outer part 31 from.

Wenn infolge einer hohen Auftreffgeschwindigkeit der Möbeltür eine hohe Kraft auf die Kolbenstange 9 wirkt, die in der Stellschraube 11 festgelegt ist, wird das Gehäuseinnenteil 32 gegen die Kraft der Druckfeder 33 im Gehäuseaußenteil 31 nach rechts in Fig. 7 bewegt. Die auf das Gehäuseaußenteil 31 des Dämpfergehäuses 5 und somit auf dessen Befestigung am Frontrahmen 2 wirkende Kraftspitze wird dadurch in der schon vorher beschriebenen Weise erheblich gemildert.If a high force acts on the piston rod 9 due to a high impact speed of the furniture door, which is fixed in the adjusting screw 11, the housing inner part 32 against the force of the compression spring 33 in the housing outer part 31 to the right in Fig. 7 emotional. The forces acting on the housing outer part 31 of the damper housing 5 and thus on its attachment to the front frame 2 force peak is thereby significantly mitigated in the manner previously described.
