Description

Die vorliegende. Erfindung bezieht sich auf eine Dämpfvorrichtung für bewegbare Möbelteile mit einem Gehäuse und einem im Gehäuse angeordneten Zylinder, in dem ein Kolben mit einer Kolbenstange verschiebbar gelagert ist.The present. The invention relates to a damping device for movable furniture parts with a housing and a cylinder arranged in the housing, in which a piston is slidably mounted with a piston rod.

Derartige Dämpfvorrichtungen sind bereits bekannt und dienen dazu, die beim schwungvollen Schließen von bewegbaren Möbelteilen, wie Türen oder Schubladen, auftretenden Schlaggeräusche und mechanische Beanspruchungen weitgehend zu reduzieren. Bekannte Dämpfvorrichtungen sind auf Mittelwerte, d.h. auf mittlere Gewichte von Türen oder Schubladen abgestimmt. Um bereits montierte Dämpfvomchtungen optimal an das Möbel bzw. an die zu dämpfenden bewegbaren Möbelteile anzupassen, ist eine individuelle Anpassung wünschenswert.Such damping devices are already known and serve to reduce the impact sounds and mechanical stresses occurring during the swinging closing of movable furniture parts, such as doors or drawers. Known damping devices are based on mean values, i. tuned to middle weights of doors or drawers. To optimally adapt already mounted Dämpfvomchtungen to the furniture or to be damped movable furniture parts, an individual adaptation is desirable.

Aufgabe der vorliegenden Erfindung ist es daher, eine Dämpfvorrichtung der eingangs erwähnten Gattung vorzuschlagen, die sich durch eine größtmögliche Flexibilität und Einsetzbarkeit auszeichnet.Object of the present invention is therefore to propose a damping device of the type mentioned, which is characterized by the greatest possible flexibility and usability.

Dies wird erfindungsgemäß in einer vorteilhaften Ausgestaltung dadurch erreicht, dass am Gehäuse mindestens eine Verstelleinrichtung gelagert ist, über die ein Anschlag für die Kolbenstange relativ zum Gehäuse verstellbar ist.This is inventively achieved in an advantageous embodiment in that at least one adjusting device is mounted on the housing, via which a stop for the piston rod is adjustable relative to the housing.

Durch die vorgesehene Verstelleinrichtung kann die Dämpfvorrichtung ideal an die jeweiligen Türen, Klappen oder Schubladen angepasst werden, da der Zylinder in Bezug zum Gehäuse verstellbar ist, sodass der Auftreffpunkt des bewegbaren Möbelteiles exakt einstellbar ist. Andererseits kann damit auch die Kennlinie bzw. die Dämpfcharakteristik der Dämpfvorrichtung gezielt beeinflusst werden, da eine Anpassung an die unterschiedlichen Gewichte der bewegbaren Möbelteile und an die unterschiedlichen Kräfte von Scharnieren oder Einzugsvorrichtungen erfolgen kann.The proposed adjusting the damping device can be ideally adapted to the respective doors, flaps or drawers, since the cylinder is adjustable relative to the housing, so that the point of impact of the movable furniture part is precisely adjustable. On the other hand, the characteristic curve or the damping characteristic of the damping device can thus be influenced in a targeted manner, since an adaptation to the different weights of the movable furniture parts and to the different forces of hinges or catching devices can take place.

Dabei kann es von Vorteil sein, wenn das Getriebe eine Drehbewegung des Betätigungselementes in eine Linearbewegung des Zylinders und/oder des Anschlages umwandelt.It may be advantageous if the transmission converts a rotational movement of the actuating element into a linear movement of the cylinder and / or the stop.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass der Anschlag topfförmig ausgebildet ist. Die in dem topfförmigen Anschlag abgestützte und/oder verankerte Kolbenstange kann dadurch eine stabile und verrutschsichere Aufnahme finden. Dabei kann es von Vorteil sein, wenn der Anschlag eine Ausnehmung aufweist, die für die Aufnahme der Kolbenstange, vorzugsweise für das freie Ende derselben, vorgesehen ist.An advantageous embodiment of the invention provides that the stop is cup-shaped. The supported in the cup-shaped stop and / or anchored Piston rod can thereby find a stable and slip-proof recording. It may be advantageous if the stop has a recess which is provided for receiving the piston rod, preferably for the free end thereof.

Vorteilhaft ist vorgesehen; dass der Zylinder zweiteilig ausgebildet ist, wobei der den Kolben aufnehmende Innenzylinder von einer aufgeschobenen Hülse umgeben ist. Die Hülse kann dabei als Schieber ausgeführt werden, der dem bewegbaren Möbelteil eine größere und damit sichere Kontaktfläche als der Zylinder selbst bietet. Um den Auftreffpunkt des bewegbaren Möbelteils auf den Dämpfer zu beeinflussen, kann es von Vorteil sein, dass an der Stirnseite des Innenzylinders oder der Hülse ein Verstellelement in Form einer Schraube angeordnet ist, die in axialer Richtung des Gehäuses bewegbar gelagert ist.Advantageously, it is provided; that the cylinder is formed in two parts, wherein the piston receiving the inner cylinder is surrounded by a pushed sleeve. The sleeve can be designed as a slider, which offers the movable furniture part a larger and thus secure contact surface as the cylinder itself. In order to influence the impact point of the movable furniture part on the damper, it may be advantageous that on the end face of the inner cylinder or the sleeve, an adjusting element is arranged in the form of a screw which is movably mounted in the axial direction of the housing.

Der Dämpfer selbst kann in üblicher Weise als Fluiddämpfer ausgeführt werden, der mit einem Arbeitsfluid, beispielsweise Öl oder Luft, befüllbar ist. Dabei kann es von Vorteil seil, zusätzlich zur Fluiddämpfung auch einen Kraftspeicher, vorzugsweise eine Feder im Zylinder vorzusehen.The damper itself can be carried out in the usual way as a fluid damper, which can be filled with a working fluid, such as oil or air. It may be advantageous rope, in addition to the fluid damping and an energy storage, preferably provide a spring in the cylinder.

Eine weitere mögliche Variante der Erfindung, in der die Dämpfvorrichtung ein Gehäuse und einen im Gehäuse angeordneten Zylinder aufweist, wobei im Zylinder ein Kolben mit einer Kolbenstange verschiebbar gelagert ist, sieht vor, dass zur Verstellung des Zylinders relativ zum Gehäuse eine erste Verstelleinrichtung vorgesehen ist, und zur Verstellung eines Anschlages für die Kolbenstange eine gesonderte zweite Verstelleinrichtung angeordnet ist.A further possible variant of the invention, in which the damping device has a housing and a cylinder arranged in the housing, wherein a piston is mounted displaceably in the cylinder with a piston rod, provides that a first adjusting device is provided for adjusting the cylinder relative to the housing, and a separate second adjustment is arranged for adjusting a stop for the piston rod.

Dabei kann es zweckmäßig sein, wenn die erste Verstelleinrichtung vorzugsweise von einem Schneckengetriebe gebildet ist, wodurch die Lage des Zylinders relativ zum Gehäuse veränderbar ist. Vorteilhaft ist vorgesehen, wenn die zweite Verstelleinrichtung von einer Schraube gebildet ist, durch die die Lage der Kolbenstange relativ zum Zylinder veränderbar ist. In diesem Zusammenhang kann vorgesehen sein, dass sich die Schraube vorzugsweise an einer Stirnseite des Gehäuses oder des Anschlages abstützt und dass die Schraube außerhalb des Gehäuses betätigbar ist.It may be expedient if the first adjusting device is preferably formed by a worm gear, whereby the position of the cylinder is variable relative to the housing. It is advantageously provided that the second adjusting device is formed by a screw, by means of which the position of the piston rod relative to the cylinder is variable. In this context, it may be provided that the screw is preferably supported on an end face of the housing or the stop and that the screw outside the housing is actuated.

Schließlich sieht ein Ausführungsbeispiel der Erfindung vor, dass das Gehäuse wenigstens einen, vorzugsweise zwei, Befestigungsflansch(e) aufweist, die zur Befestigung an einem Möbel und/oder einem bewegbaren Möbelteil desselben befestigbar ist (sind).Finally, an exemplary embodiment of the invention provides that the housing has at least one, preferably two, mounting flange (s) which can be fastened for attachment to a furniture and / or a movable furniture part thereof.

Fig. 1a zeigt eine Explosionsdarstellung der erfindungsgemäßen Dämpfvorrichtung 1, Fig. 1b zeigt die Dämpfvorrichtung 1 im zusammengebauten Zustand. Die Dämpfvorrichtung 1 umfasst ein Gehäuse 2, in dem ein Zylinder 3 mit der Kolbenstange 5 verschiebbar gelagert ist. Zur Bewegung des Zylinders 3 ist ein Getriebe 6 vorgesehen, das im gezeigten Ausführungsbeispiel als Schneckengetriebe ausgeführt ist. Das Getriebe 6 umfasst einen in axialer Richtung des Gehäuses 2 verschiebbaren Anschlag 7, der durch die Schnecke 14 gebildet ist. Zur Axialverschiebung der Schnecke 14 ist das Betätigungselement 9 in Form eines Schneckenrades vorgesehen, das vorzugsweise mittels eines Schraubendrehers betätigbar ist. Das Betätigungselement 9 ist - bezogen auf die Längsachse des Zylinders 3 - seitlich am Gehäuse 2 beweglich, vorzugsweise drehbar, gelagert. Vorteilhaft ist vorgesehen, dass die Drehachse des Betätigungselementes 9 quer, vorzugsweise im Wesentlichen unter einem Winkel von 90°, zur Längsachse des Zylinders 3 verläuft. Damit wird erreicht, dass das Betätigungselement 9 bei einem Gehäuse 2 mit kreisförmigen, ovalen oder polygonalen Querschnitt an dessen Mantelftäche von außen zugänglich ist, wobei eine leichte Erreichbarkeit des Betätigungselementes 9 bei einer bereits in oder an einem Möbel montierten Dämpfvorrichtung 1 ermöglicht wird. Dabei kann es zweckmäßig sein, wenn der Winkel zwischen der Achse 12 der Schnecke 14 und der Achse 13 des Schneckenrades 9 vorzugsweise im Wesentlichen 90° beträgt. Die Schnecke 14 weist an ihrer Oberseite Zähne 11 auf, die mit dem Schneckenrad 9 in Eingriff bringbar sind. Eine Drehbewegung des Schneckenrades 9 wird in eine Linearbewegung der Schnecke 14 umgesetzt. Die Kolbenstange 5 steht dabei immer am geschlossenen Boden der topfförmig ausgebildeten Schnecke 14 an, sodass bei einer Verschiebung der Schnecke 14 auch eine Verschiebung des Zylinders 3 relativ zum Gehäuse 2 erfolgt. An der kolbenabgewandten Seite des Zylinders 3 kann eine Hülse 8 aufgeschoben werden, die beim Dämpfvorgang mit dem zu dämpfenden Möbelteil in Kontakt tritt. Fig. 1b zeigt die zusammengebaute Dämpfvorrichtung 1, wobei durch Drehung des Schneckenrades 9 eine Verschiebung des Zylinders 3 samt darauf geschobener Hülse 8 relativ zum Gehäuse 2 erfolgt. Fig. 1a shows an exploded view of the damping device 1 according to the invention, Fig. 1b shows the damping device 1 in the assembled state. The damping device 1 comprises a housing 2, in which a cylinder 3 is slidably mounted with the piston rod 5. For the movement of the cylinder 3, a gear 6 is provided, which is designed in the illustrated embodiment as a worm gear. The gear 6 comprises a displaceable in the axial direction of the housing 2 stop 7, which is formed by the screw 14. For axial displacement of the screw 14, the actuating element 9 is provided in the form of a worm wheel, which is preferably actuated by means of a screwdriver. The actuating element 9 is - relative to the longitudinal axis of the cylinder 3 - laterally on the housing 2 movable, preferably rotatably mounted. It is advantageously provided that the axis of rotation of the actuating element 9 extends transversely, preferably substantially at an angle of 90 °, to the longitudinal axis of the cylinder 3. This ensures that the actuator 9 is accessible from the outside in a housing 2 with a circular, oval or polygonal cross-section on the Mantelftäche, with an easy accessibility of the actuating element 9 in an already in or on a piece of furniture mounted damper device 1 is enabled. It may be expedient if the angle between the axis 12 of the screw 14 and the axis 13 of the worm wheel 9 is preferably substantially 90 °. The worm 14 has on its upper side teeth 11 which are engageable with the worm wheel 9 in engagement. A rotational movement of the worm wheel 9 is converted into a linear movement of the worm 14. The piston rod 5 is always on the closed bottom of the cup-shaped screw 14, so that upon displacement of the screw 14 and a displacement of the cylinder 3 takes place relative to the housing 2. At the piston side facing away from the cylinder 3, a sleeve 8 can be pushed, which comes into contact with the damping to be damped furniture part during the damping process. Fig. 1b shows the assembled damping device 1, wherein by rotation of the worm wheel 9, a displacement of the cylinder 3 together with the sleeve 8 pushed thereon takes place relative to the housing 2.

Fig. 2a zeigt eine Draufsicht auf die Dämpfvorrichtung 1. Durch Drehung des Schneckenrades 9 kann der nicht ersichtliche Zylinder 3 samt der Hülse 8 relativ zum Gehäuse 2 verstellt werden. Zur Befestigung an einem Möbel bzw. an einem bewegbaren Möbelteil sind auf beiden Seiten des Gehäuses 2 Befestigungsflansche 10 vorgesehen. Fig. 2b zeigt einen Vertikalschnitt entlang der Achse A-A aus Fig. 2a. Zu erkennen ist das Gehäuse 2, in dem die Schnecke 14 verstellbar gelagert ist. Das Schneckenrad 9 greift mit seiner Verzahnung in die Zähne 11. der Schnecke 14 ein, sodass bei einer Drehung des Schneckenrades 9 eine axiale Verschiebung der Schnecke 14 relativ zum Gehäuse 2 erfolgt. Das freie Ende der Kolbenstange 5 lagert in einer Ausnehmung 15 der Schnecke 14, wobei die Kolbenstange 5 sich ständig am Boden der topfförmig ausgebildeten Schnecke 14 abstützt. Bei einer axialen Verschiebung der Schnecke 14 wird somit der gesamte Zylinder 3 verschoben. An der Kolbenstange 5 ist ein Kolben 4 ausgebildet, der innerhalb des Zylinders 3 geführt ist. Auf den Zylinder 3 ist eine Hülse 8 aufgeschoben, die auf das zu dämpfende Möbelteil auftrifft. Zur Begrenzung der axialen Verschiebbarkeit in der inneren Endlage der Schnecke relativ zum Gehäuse ist ein, vorzugsweise ringförmiges Begrenzungselement 16 vorgesehen, das in der inneren Endlage der Schnecke 14 mit einem am Gehäuse 2 angeordneten Gegenanschlag 16' zusammenwirkt. Bei diesem Ausführungsbeispiel ist eine Veränderung der Kennlinie bzw. der Dämpfcharakteristik nicht vorgesehen. Fig. 2a shows a plan view of the damping device 1. By rotation of the worm wheel 9, the non-apparent cylinder 3 together with the sleeve 8 can be adjusted relative to the housing 2. For attachment to a piece of furniture or to a movable furniture part 2 mounting flanges 10 are provided on both sides of the housing. Fig. 2b shows a vertical section along the axis AA Fig. 2a , Evident is the housing 2, in which the screw 14 is adjustably mounted. The worm wheel 9 engages with its toothing in the teeth 11 of the screw 14, so that upon rotation of the worm wheel 9, an axial displacement of the screw 14 takes place relative to the housing 2. The free end of the piston rod 5 is supported in a recess 15 of the screw 14, wherein the piston rod 5 is constantly supported on the bottom of the cup-shaped screw 14. With an axial displacement of the screw 14 thus the entire cylinder 3 is moved. On the piston rod 5, a piston 4 is formed, which is guided within the cylinder 3. On the cylinder 3, a sleeve 8 is pushed, which impinges on the furniture part to be damped. To limit the axial displaceability in the inner end position of the screw relative to the housing, a, preferably annular limiting element 16 is provided, which cooperates in the inner end position of the screw 14 with a housing 2 arranged on the counter-stop 16 '. In this embodiment, a change of the characteristic or the damping characteristic is not provided.

Fig. 3a-3c zeigen verschiedene Stellungen des Zylinders 3 in Bezug zum Gehäuse 2. Fig. 3a zeigt die Schnecke 14 in der hintersten Stellung relativ zum Gehäuse 2. In dieser Position liegen das Begrenzungselement 16 und der Gegenanschlag 16' des Gehäuses 2 aneinander an. Durch Drehung des Schneckenrades 9 wird die Schnecke 14 allmählich nach rechts verschoben. Fig. 3b zeigt eine mittlere Stellung der Schnecke 14 bzw. des Zylinders 3 in Bezug zum Gehäuse 2, während Fig. 3c die äußere Endstellung der Schnecke 14 bzw. des Zylinders 3 relativ zum Gehäuse 2 zeigt. In dieser Position sind das Begrenzungselement 16 und der Gegenanschlag 16' voneinander beabstandet. Fig. 3a-3c show different positions of the cylinder 3 with respect to the housing. 2 Fig. 3a shows the screw 14 in the rearmost position relative to the housing 2. In this position, the limiting element 16 and the counter-stop 16 'of the housing 2 are adjacent to each other at. By rotation of the worm wheel 9, the screw 14 is gradually shifted to the right. Fig. 3b shows a mean position of the screw 14 and the cylinder 3 with respect to the housing 2, while Fig. 3c the outer end position of the screw 14 and the cylinder 3 relative to the housing 2 shows. In this position, the limiting element 16 and the counter-stop 16 'are spaced from each other.

Fig. 4a-4c zeigen die vergrößerten Detailansichten J, P, O aus den Fig. 3a-3c. Fig. 4a zeigt die Schnecke 14 bzw. den Zylinder 3 in der inneren Endstellung in Bezug zum Gehäuse 2, in der das Begrenzungselement 16 an dem Gegenanschlag 16' anliegt. Die Hülse 8 weist einen Rastvorsprung 17 auf, der an einem an der Schnecke 14 angeordneten Rastvorsprung 17' ständig anliegt. Fig. 4b zeigt die mittlere Stellung der Schnecke 14 bzw. des Zylinders 3, wobei das Begrenzungselement 16 von dem Gegenanschlag 16' beabstandet ist. Fig. 4c zeigt die Maximalverstellung der Schnecke 14 bzw. des Zylinders 3, um das Differenzmaß Δx. Fig. 4a-4c show the enlarged detail views J, P, O from the Fig. 3a-3c , Fig. 4a shows the screw 14 and the cylinder 3 in the inner end position with respect to the housing 2, in which the limiting element 16 abuts against the counter-stop 16 '. The sleeve 8 has a latching projection 17 which rests permanently on a latching projection 17 'arranged on the screw 14. Fig. 4b shows the middle position of the screw 14 and the cylinder 3, wherein the limiting element 16 is spaced from the counter-stop 16 '. Fig. 4c shows the maximum displacement of the screw 14 and the cylinder 3, by the difference measure Δx.

Fig. 5a zeigt ein weiteres Ausführungsbeispiel der Erfindung mit zwei gesonderten Verstelleinrichtungen 18 und 19. Die erste Verstelleinrichtung 18 umfasst das bereits beschriebene Schneckengetriebe mit der Schnecke 14 und dem Schneckenrad 9. Die erste Verstelleinrichtung 18 ist für die Verstellung des Zylinders 3 relativ zum Gehäuse 2 vorgesehen. Zusätzlich zu der ersten Verstelleinrichtung 9 ist eine zweite Verstelleinrichtung 19 vorgesehen, mit der die Kolbenstange 5 relativ zum Zylinder 3 verstellt werden kann. Hierdurch wird die Kennlinie der Dämpfvorrichtung 1 bzw. deren Dämpfcharakteristik beeinflusst. Die zweite Verstelleinrichtung 19 weist eine Schraube 20 auf, die sich an der Stirnseite der Schnecke 14 abstützt, wobei die Schnecke 14 als Anschlag 7 für die Kolbenstange 5 dient. Durch die erste Verstelleinrichtung 18 wird eine axiale Verschiebung der Schnecke 14 blockiert, bei Betätigung der Schraube 20 wird folglich die Kolbenstange 5 bzw. der Kolben 4 relativ zum Zylinder 4 verschoben. Durch Verdrehen der Schraube 20 im Uhrzeigersinn wird der Kolben 4 weiter in den Zylinder 3 hineingedrückt, sodass ein kürzerer Dämpfweg bis zum vollständigen Eindrücken des Kolbens 4 in den Zylinder 3 verbleibt. Bei Drehung der Schraube 20 im Gegenuhrzeigersinn wird der Kolben 4 bzw. die Kolbenstange 5 weiter aus dem Zylinder 3 herausbewegt, sodass ein längerer Dämpfweg des Kolbens 4 bis hin zur vollständig eingedrückten Stellung desselben die Folge ist. Fig. 5b zeigt eine vergrößerte Darstellung des Details aus Fig. 5a. Die Schnecke 14 wurde mit Hilfe der ersten Verstelleinrichtung 18 so weit in das Innere des Gehäuses 2 verschoben, sodass das Begrenzungselement 16 der Schnecke 14 und der Gegenanschlag 16' des Gehäuses 2 voneinander beabstandet sind. Die axiale Lage der Schnecke 14 bleibt unveränderlich, durch Betätigen der zweiten Verstelleinrichtung 19 kann die Dämpfcharakteristik der Dämpfvorrichtung 1 eingestellt werden. Fig. 5a shows a further embodiment of the invention with two separate adjusting devices 18 and 19. The first adjusting device 18 includes the already described worm gear with the worm 14 and the worm wheel 9. The first adjusting device 18 is provided for the adjustment of the cylinder 3 relative to the housing 2. In addition to the first adjusting device 9, a second adjusting device 19 is provided with which the piston rod 5 can be adjusted relative to the cylinder 3. As a result, the characteristic of the damping device 1 or its damping characteristic is influenced. The second adjusting device 19 has a screw 20 which is supported on the end face of the screw 14, wherein the screw 14 serves as a stop 7 for the piston rod 5. By the first adjusting device 18, an axial displacement of the screw 14 is blocked, upon actuation of the screw 20, consequently, the piston rod 5 and the piston 4 is displaced relative to the cylinder 4. By turning the screw 20 in a clockwise direction, the piston 4 is further pressed into the cylinder 3, so that a shorter Dämpfweg remains until the complete depression of the piston 4 in the cylinder 3. Upon rotation of the screw 20 in a counterclockwise direction, the piston 4 or the piston rod 5 is further moved out of the cylinder 3, so that a longer Dämpfweg of the piston 4 to the fully depressed position thereof is the result. Fig. 5b shows an enlarged view of the details Fig. 5a , The screw 14 has been moved with the aid of the first adjusting device 18 so far into the interior of the housing 2, so that the limiting element 16 of the screw 14 and the counter-stop 16 'of the housing. 2 spaced apart from each other. The axial position of the screw 14 remains invariable, by operating the second adjusting device 19, the damping characteristic of the damping device 1 can be adjusted.

Fig. 5c und die vergrößerte Detaildarstellung in Fig. 5d zeigen ein alternatives Ausführungsbeispiel zu der in Fig. 5a bzw. Fig. 5b gezeigten Dämpfvorrichtung 1, wobei die Dämpfcharakteristik bzw. die Kennlinie der Dämpfvorrichtung 1 durch das Schneckenrad 9 einstellbar ist. Um eine weitere axiale Verschiebung des Zylinders 3 zu verhindern, ist am (Innen-)Zylinder 3 bzw. an dessen Hülse 8 ein erster Vorsprung 21 angeordnet oder ausgebildet, der vorzugsweise in der äußeren Endstellung des Zylinders 3 bzw. dessen Hülse 8 relativ zum Gehäuse 2 zusammenwirkt, sodass eine weitere axiale Verschiebung des Zylinders 3 zum Gehäuse 2 verhindert wird. Die Kolbenstange 5 stützt sich dabei wieder an der topfförmig ausgebildeten Schnecke 14 ab, wobei die Schnecke 14 durch das Schneckenrad 9 in axialer Richtung des Gehäuses 2 verschiebbar ist. Da eine weitere axiale Verschiebung durch die zusammenwirkenden Vorsprünge 21, 22 verhindert wird, kann bei Betätigung des Schneckenrades 9 die Kolbenstange 5 bzw. der Kolben 4 mehr oder weniger weit in den Zylinder 3 eingeschoben werden. Je nach Position der Kolbenstange 5 bzw. des Kolbens 4 in Bezug zum Zylinder 3 kann die Dämpfcharakteristik der Dämpfvorrichtung 1 unterschiedlich gestaltet werden. Fig. 5c and the enlarged detail view in Fig. 5d show an alternative embodiment to that in Fig. 5a respectively. Fig. 5b shown damping device 1, wherein the damping characteristic or the characteristic of the damping device 1 by the worm wheel 9 is adjustable. In order to prevent a further axial displacement of the cylinder 3, a first projection 21 is arranged or formed on the (inner) cylinder 3 or on its sleeve 8, preferably in the outer end position of the cylinder 3 or its sleeve 8 relative to the housing 2 cooperates, so that a further axial displacement of the cylinder 3 to the housing 2 is prevented. The piston rod 5 is supported again on the cup-shaped screw 14, wherein the screw 14 is displaceable by the worm wheel 9 in the axial direction of the housing 2. Since a further axial displacement is prevented by the cooperating projections 21, 22, upon actuation of the worm wheel 9, the piston rod 5 and the piston 4 can be more or less inserted into the cylinder 3. Depending on the position of the piston rod 5 and the piston 4 with respect to the cylinder 3, the damping characteristic of the damping device 1 can be designed differently.

Fig. 6a zeigt eine Explosionsdarstellung des Ausführungsbeispiels aus Fig. 5c bzw. Fig. 5d, bei der durch Verstellen des Schneckenrades 9 die Kennlinie der Dämpfvorrichtung 1 verstellbar ist. Das Gehäuse 2 weist einen Vorsprung 22 auf, der mit einem Vorsprung 21 der Hülse 8 zusammenwirkt, um ein weiteres Herausbewegen des Zylinders 3 in Bezug zum Gehäuse 2 zu vermeiden. Der Anschlag 7 wird von der topfförmigen Schnecke 14 gebildet, deren Zähne 11 mit dem Schneckenrad 9 in Eingriff bringbar sind. Fig. 6b zeigt die Dämpfvorrichtung 1 im zusammengebauten Zustand. Fig. 6a shows an exploded view of the embodiment Fig. 5c respectively. Fig. 5d in which by adjusting the worm wheel 9, the characteristic of the damping device 1 is adjustable. The housing 2 has a projection 22 which cooperates with a projection 21 of the sleeve 8 to prevent further movement of the cylinder 3 with respect to the housing 2. The stopper 7 is formed by the cup-shaped screw 14, the teeth 11 are engageable with the worm wheel 9 in engagement. Fig. 6b shows the damping device 1 in the assembled state.

Fig. 7a-7c zeigen ein weiteres Ausführungsbeispiel der Erfindung. Das Gehäuse 2 weist an seiner Stirnseite eine Verstelleinrichtung 19 auf, die im gezeigten Ausführungsbeispiel eine in axialer Richtung des Gehäuses 2 verstellbare Rändelschraube 20 umfasst, die außerhalb des Gehäuses 2 zugänglich bzw. betätigbar ist. Die Rändelschraube 20 bildet also einen verschiebbaren Anschlag für die Kolbenstange 5, an der ein Kolben 4 ausgebildet ist. Der Zylinder 3 weist eine Verjüngung 25 auf, sodass bei Herausdrehen der Rändelschraube 20 auch der Kolben 4 nach rechts bewegt wird und auch ein zwischen Kolben 4 und Zylinderwand gebildeter Ringspalt größer wird. Beim Einschieben des Zylinders 3 relativ zum Kolben 4 entgegen der Kraft der Feder 23 erfolgt je nach Stellung des Kolbens 4 eine unterschiedliche Dämpfung. An der Stirnseite des Zylinders 3 ist ein Verstellrad 24 gelagert, welches in axialer Richtung des Zylinders 3 verstellbar ist. Der Zylinder 3 kann damit virtuell verlängert werden, sodass bei bereits montierter Dämpfvorrichtung 1 auch der Auftreffpunkt eines zu dämpfenden Möbelteiles exakt festlegbar ist. Fig. 7a-7c show a further embodiment of the invention. The housing 2 has on its end face an adjusting device 19, which in the illustrated embodiment comprises an adjustable in the axial direction of the housing 2 knurled screw 20 which is accessible or actuated outside the housing 2. The thumbscrew 20 thus forms a displaceable stop for the piston rod 5, on which a piston 4 is formed. The cylinder 3 has a taper 25 so that when unscrewing the thumbscrew 20 and the piston 4 is moved to the right and also between a piston 4 and Cylinder wall formed annular gap is larger. When inserting the cylinder 3 relative to the piston 4 against the force of the spring 23 takes place depending on the position of the piston 4, a different damping. On the front side of the cylinder 3, an adjusting wheel 24 is mounted, which in the axial direction of the cylinder 3 is adjustable. The cylinder 3 can thus be virtually extended so that when already mounted damping device 1 and the point of impact of a furniture part to be damped is exactly fixed.

Fig. 8a-8c zeigen das Ausführungsbeispiel aus den Fig. 7a-7c, wobei Fig. 8a und 8b eine unterschiedliche Stellung des Verstellrades 24 zeigt. Durch die Verstellung des Verstellrades 24 wird die Kennlinie der Dämpfvorrichtung 1 nicht beeinflusst. Eine Änderung der Dämpfcharakteristik erfolgt durch die Rändelschraube 20. Fig. 8c zeigt schematisch eine Draufsicht der Dämpfvorrichtung 1. Fig. 8a-8c show the embodiment of the Fig. 7a-7c , in which Fig. 8a and 8b a different position of the adjusting wheel 24 shows. By adjusting the Verstellrades 24, the characteristic of the damping device 1 is not affected. A change in the damping characteristic is effected by the knurled screw 20. Fig. 8c schematically shows a plan view of the damping device. 1
