Abstract

The damper system for a drawer comprises a pivoting slide (13) attached to the drawer. The inner end of this forms part of a rack and pinion system. The teeth (17, 30) of the rack and pinion slope in opposite directions so that a toothed sleeve on the outside of the pinion is pressed on to its core and moves with it while the drawer is closing but is raised from it and acts as a freewheel mechanism during opening.

Description

Die vorliegende Erfindung betrifft eine Dämpfungsvorrichtung für bewegbare Möbelteile, mit einem mit dem Möbelteil kuppelbaren Betätigungsteil, das entsprechend einer Möbelteilbewegung hin- und herbewegbar gelagert ist, einem Dämpfer sowie einer Getriebestufe zur Umsetzung von Bewegungen des Betätigungsteils in Bewegungen des Dämpfers.The present invention relates to a damping device for movable furniture parts, with an engageable with the furniture part operating part, which is mounted according to a furniture part movement back and forth, a damper and a gear stage for the implementation of movements of the operating part in movements of the damper.

Aus der EP 1 188 397 ist eine federbeaufschlagte Schließvorrichtung für Schubladen bekannt, bei der ein axial verschieblicher Schieber beim anfänglichen Aufmachen einer Schublade eine Feder spannt und im gespannten Zustand verriegelt. Beim Zurückschieben der Schublade wird das Betätigungsteil von der Schublade erfasst und gelöst, so dass die Feder die Schublade vollständig zurückzieht. Dabei ist ein an dem Betätigungsteil befestigter Flansch in einer Schiebeführung geführt, die mit hochviskosem Fett befüllt ist. Durch das hochviskose Fett wird eine Dämpfung der Bewegung erzielt.From EP 1 188 397 a spring-loaded closing device for drawers is known in which an axially displaceable slide biases a spring during the initial opening of a drawer and locks it in the tensioned state. When pushing back the drawer, the operating part is caught by the drawer and released, so that the spring completely retracts the drawer. In this case, a fixed to the operating part flange is guided in a sliding guide, which is filled with high-viscosity grease. Due to the high-viscosity grease, a damping of the movement is achieved.

Aus der EP 1 120 066 ist weiterhin eine Schließvorrichtung für Schubladen bekannt, bei der ein verschieblich geführter Betätigungsschlitten mit der Schublade kuppelbar ist. Über eine Verzahnung betätigt der Betätigungsschlitten über ein Getrieberitzel einen Rotationsdämpfer, der ein sanftes Schließen der Schublade sicherstellt.From EP 1 120 066 a closure device for drawers is also known, in which a slidably guided actuating slide with the drawer can be coupled is. About a toothing of the actuating slide via a gear pinion actuates a rotary damper, which ensures a smooth closing of the drawer.

Solche Dämpfungsvorrichtungen bewirken zwar ein sanftes Schließen der Schublade. Allerdings ist die Dämpfungswirkung beim Aufmachen der Schublade unerwünscht. Um die Dämpfungswirkung beim Aufmachen der Schublade zu vermeiden, wurde bereits vorgeschlagen, nur in einer Richtung wirksame Rotationsdämpfer zu verwenden. Diese Rotationsdämpfer bewirken nur in einer Richtung eine Dämpfung. In der entgegengesetzten Richtung, die dem Ausziehen der Schublade entspricht, ist die Dämpfungswirkung vernachlässigbar. Solche Rotationsdämpfer sind jedoch sehr teuer und damit für die Massenfertigung von entsprechenden Möbelbeschlägen wenig geeignet.Although such damping devices cause a gentle closing of the drawer. However, the damping effect when opening the drawer is undesirable. To avoid the damping effect when opening the drawer, it has already been proposed to use effective in one direction only rotary damper. These rotary dampers cause damping only in one direction. In the opposite direction, which corresponds to the extension of the drawer, the damping effect is negligible. However, such rotary dampers are very expensive and therefore not very suitable for the mass production of corresponding furniture fittings.

Aus der US 5,135,294 ist es bekannt, einer Schublade einen Bewegungsdämpfer zuzuordnen, der die Schublade beim Zuschieben dämpft und beim Herausziehen der Schublade durch einen Freilauf unwirksam gemacht wird. Konkret ist an der Schublade ein Rotationsdämpfer befestigt, der durch eine in der Schubladenführung vorgesehene Zahnstange betätigt wird. Dabei ist zwischen dem mit der Zahnstange kämmenden Ritzel und dem eigentlichen Dämpfungsrotor eine Spiralfeder vorgesehen, die sich je nach Bewegungsrichtung weiter aufzieht oder enger zusammenzieht, so dass die Spiralfeder den von ihr umschlossenen Rotor entweder freigibt oder fest umschlingt.From US 5,135,294 it is known to assign a drawer a motion damper, which dampens the drawer when sliding and is made ineffective when pulling out the drawer by a freewheel. Specifically, a rotary damper is attached to the drawer, which is actuated by a provided in the drawer slide rack. It is provided between the meshing with the rack pinion and the actual damping rotor, a coil spring which continues depending on the direction of movement or pulls closer together, so that the coil spring either the rotor enclosed by it releases or tightly wraps around.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte Dämpfungsvorrichtung der eingangs genannten Art zu schaffen, die Nachteile des Standes der Technik vermeidet und letzteren in vorteilhafter Weise weiterbildet. Vorzugsweise soll die Dämpfungsvorrichtung mit einfachen Mitteln eine Dämpfungswirkung nur in einer Bewegungsrichtung erzielen, während in der entgegengesetzten Richtung eine weitgehend dämpfungsfreie Bewegung möglich ist.The present invention is therefore an object of the invention to provide an improved damping device of the type mentioned above, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner. Preferably, the damping device should achieve a damping effect only in one direction of movement with simple means, while in the opposite direction a largely damping-free movement is possible.

Erfindungsgemäß wird diese Aufgabe durch eine Dämpfungsvorrichtung gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.According to the invention this object is achieved by a damping device according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

Erfindungsgemäß ist die Getriebestufe zwischen dem Betätigungsteil und dem Dämpfer also derart ausgebildet, dass sie nur Bewegungen des Betätigungsteils in eine Richtung in Dämpferbewegungen umsetzt, während sie Bewegungen des Betätigungsteils in die entgegengesetzte Richtung nicht in Dämpferbewegungen umsetzt. Die Getriebestufe enthält hierzu eine Freilaufkupplung, die bei Bewegungen des Betätigungsteils in eine erste Richtung einkuppelt und bei Bewegungen des Betätigungsteils in eine zweite, zur ersten Richtung entgegengesetzte Richtung auskuppelt. Vorteilhafterweise können hierdurch billige, in zwei Richtungen wirksame Dämpfer Verwendung finden, ohne dass tatsächlich in zwei Bewegungsrichtungen eine Dämpfungswirkung eintritt. Es werden insbesondere nur Schließbewegungen des Betätigungsteils in Dämpferbewegungen umgesetzt, während beim Öffnen des Möbelteils der Dämpfer keine Bewegung erfährt.According to the invention, the gear stage between the actuating part and the damper is thus designed such that it converts only movements of the actuating part in one direction in damper movements, while not converting movements of the actuating part in the opposite direction in damper movements. For this purpose, the gear stage includes an overrunning clutch, which engages in a first direction during movements of the actuating part and disengages in a second direction opposite to the first direction during movements of the actuating part. Advantageously, this means that cheap, bidirectional dampers can be used without a damping effect actually occurring in two directions of movement. In particular, only closing movements of the operating part are converted into damper movements, while the damper does not undergo any movement when the furniture part is opened.

Dabei wird die Freilaufkupplung von einem kraftübertragenden drehbar gelagerten Getriebeelement der Getriebestufe gebildet, das Antriebsdrehbewegungen auf ein zweites Getriebeelement überträgt, axial in Richtung seiner Drehachse beweglich gelagert ist und durch Bewegung in die eine Richtung von dem zweiten Getriebeelement abkuppelt und durch eine entgegengesetzte Bewegung in das zweite Getriebeelement kraftübertragend einkuppelt.In this case, the one-way clutch is formed by a force-transmitting rotatably mounted gear member of the gear stage, the drive rotational movements transmits to a second transmission element, is mounted axially movable in the direction of its axis of rotation and uncouples by movement in one direction of the second gear element and by an opposite movement in the second Transmission element engages force-transmitting.

Insbesondere kann die Freilaufkupplung von einem Getrieberad der Getriebestufe gebildet sein, das axial verschieblich auf einer Getriebeachse sitzt und durch axiale Bewegung in einer ersten Richtung mit der Getriebeachse in drehfesten Eingriff und durch axiale Bewegung in die entgegengesetzte Richtung von der Getriebeachse außer Eingriff bringbar ist. Eine besonders kompakte Anordnung wird erreicht, wenn das Getrieberad unmittelbar auf dem in diesem Fall als Rotationsdämpfer ausgebildeten Dämpfer sitzt. Durch entsprechende axiale Bewegung des Getrieberads gelangt dieses vom Gehäuse des Rotationsdämpfers außer Eingriff bzw. mit diesem in Eingriff.In particular, the overrunning clutch may be formed by a gear of the gear stage, which sits axially displaceable on a transmission axis and by axial movement in a first direction with the transmission axis in rotationally fixed engagement and by axial movement in the opposite direction from the transmission axis disengageable. A particularly compact arrangement is achieved when the gear sits directly on the formed in this case as a rotary damper damper. Passed by corresponding axial movement of the gear this from the housing of the rotary damper out of engagement or with this engaged.

Um die beiden die Freilaufeigenschaft bewirkenden Getriebeelemente einfach kuppeln sowie auskuppeln zu können, besitzen die beiden Getriebeelemente vorteilhafterweise keilförmig, d.h. spitzwinklig zur Verschieberichtung des Getriebeelements geneigt, angeordnete Kupplungseingriffsflächen, die durch Relativbewegung der beiden Getriebeelemente in Eingriff und außer Eingriff bringbar sind. Die keilförmig angeordneten Kupplungseingriffsflächen erlauben es, mit kleinen Stellbewegungen eine sichere Verriegelung herzustellen sowie zu lösen.In order to be able to easily couple and uncouple the two gear elements causing the freewheeling property, the two gear elements advantageously have wedge-shaped, ie. inclined at an angle to the direction of displacement of the transmission element, arranged coupling engagement surfaces, which are engageable by relative movement of the two gear elements in engagement and disengaged. The wedge-shaped coupling engagement surfaces make it possible to establish and release a secure locking with small positioning movements.

Die Freilaufkupplung kann rein kraftschlüssig kuppelnd ausgebildet sein. Im Falle des auf der Getriebeachse axial verschieblich sitzenden Getrieberades können das Getrieberad und/oder die Getriebeachse jeweils konische Kupplungseingriffsflächen aufweisen. Die konische Innenmantelfläche des Getrieberads sitzt bei entsprechender Axialbewegung des Getrieberads kraftschlüssig auf der konischen Außenmantelfläche der Getriebeachse, die von dem Gehäuse des Rotationsdämpfers gebildet sein kann. Wird das Getrieberad axial verschoben, wird die konische Innenmantelfläche von der konischen Außenmantelfläche der Getriebeachse abgehoben. Durch die Konizität der Kupplungseingriffsflächen können große Presskräfte mit nur kleinen axialen Stellkräften erzeugt und damit große Antriebskräfte übertragen werden.The freewheel clutch can be designed to be positively frictionally coupled. In the case of sitting on the transmission axis axially displaceable gear, the gear and / or the transmission axis each have conical coupling engagement surfaces. The conical inner circumferential surface of the gear sits frictionally with appropriate axial movement of the gear on the conical outer surface of the transmission axis, which may be formed by the housing of the rotary damper. If the gear is moved axially, the conical inner surface is lifted from the conical outer surface of the transmission axis. Due to the conicity of the clutch engagement surfaces large pressing forces can be generated with only small axial restoring forces and thus large driving forces are transmitted.

Gemäß einer weiteren bevorzugten Ausführung der Erfindung kann die Freilaufkupplung auch formschlüssig kuppelnd ausgebildet sein. Im Falle des auf der Getriebeachse axial verschieblich sitzenden Getrieberads können an dem Getrieberad und/oder an der Getriebeachse keilförmig angeordnete, d.h. zur Drehachse spitzwinklig geneigte Passflächen vorgesehen sein, mit denen das Getrieberad und die Getriebeachse aufeinandersitzen. Insbesondere können an sich konische Mantelflächen an dem Getrieberad und/oder der Getriebeachse vorgesehen sein, die facettenartige Abflachungen aufweisen, welche die Passflächen bilden und mit komplementären Abflachungen an dem jeweils anderen Teil in Eingriff geraten. Ebenso können an den keilförmig angeordneten Kupplungseingriffsflächen Riefen, Nuten oder andere formschlüssig wirkende Passflächen vorgesehen sein, um bei entsprechender axialer Bewegung des Getrieberads einen drehfesten Formschluss mit der Getriebeachse zu erreichen.According to a further preferred embodiment of the invention, the one-way clutch may also be formed positively coupling. In the case of the gear wheel axially slidably seated on the transmission axis, wedge-shaped, that is, wedge-shaped, on the gear wheel and / or on the transmission axis. be provided to the axis of rotation at an acute angle inclined mating surfaces, with which the gear and the transmission axis aufsitzitzen. In particular, conical lateral surfaces may be provided on the gear wheel and / or the gear axis, which have faceted flats which form the mating surfaces and engage with complementary flattenings on the respective other part. Likewise, grooves, grooves or other form-fitting mating surfaces may be provided on the wedge-shaped coupling engagement surfaces in order to achieve a rotationally fixed positive engagement with the transmission axis with a corresponding axial movement of the gear.

Die Stellbewegung des axial verschieblichen Getriebeelements zum Schalten des Freilaufs wird in Weiterbildung der Erfindung automatisch durch Bewegung der Getriebestufe bewirkt. Die Getriebestufe kann hierzu Eingriffsmittel, insbesondere eine Schrägverzahnung, besitzen, die je nach Bewegungsrichtung der Getriebestufe unterschiedlich gerichtete resultierende Kräfte auf das axial verschiebliche Getriebeelement bewirken. Die Einrück- und Ausrückkräfte auf die Freilaufkupplung werden also durch resultierende Querkräfte des Getriebeeingriffs gebildet. Die Laufrichtung der Getriebestufe bewirkt ein automatisches Schalten der Freilaufkupplung.The adjusting movement of the axially displaceable gear element for switching the freewheel is effected in a further development of the invention automatically by movement of the gear stage. For this purpose, the gear stage can have engaging means, in particular a helical toothing, which, depending on the direction of movement of the gear stage, effect differently directed resultant forces on the axially displaceable gear element. The engagement and Ausrückkräfte on the overrunning clutch are thus formed by the resulting lateral forces of the gear engagement. The direction of the gear stage causes an automatic switching of the overrunning clutch.

Vorteilhafterweise ist der Dämpfer als Rotationsdämpfer ausgebildet, der in beide Drehrichtungen wirksam sein kann. Durch die in die Getriebestufe integrierte Freilaufkupplung kann der Dämpfer frei von Rückstellmitteln ausgebildet sein. Der Rotationsdämpfer braucht nicht jedes Mal in eine Ausgangsstellung zurückgedreht werden. Wenn die Getriebestufe beim Öffnen des beweglichen Möbelteils freiläuft, bleibt der Rotationsdämpfer einfach in der entsprechenden Stellung stehen. Kuppelt die Getriebestufe beim erneuten Schließen des Möbelteils wieder ein, wird der Rotationsdämpfer einfach entsprechend weitergedreht. Dieser Vorgang wiederholt sich, ohne dass ein Rückstellen des Rotationsdämpfers stattfinden würde. Der Rotationsdämpfer wird also immer nur in eine Bewegungsrichtung betätigt. Rückstellfedern können entfallen.Advantageously, the damper is designed as a rotary damper, which can be effective in both directions of rotation. By integrated into the gear stage one-way clutch, the damper may be formed free of return means. The rotary damper does not need to be turned back to a starting position every time. When the gear stage is freed when the movable furniture part is opened, the rotary damper simply stops in the corresponding position. When the gear unit engages again when the furniture part is closed again, the rotary damper is simply further rotated accordingly. This process is repeated without a reset of the rotary damper would take place. The rotary damper is therefore always actuated only in one direction of movement. Return springs can be omitted.

In Weiterbildung der Erfindung kann das Betätigungsteil als axial verschiebliches Zahnstangenprofil ausgebildet sein, das mit dem auf dem Dämpfer sitzenden Getrieberad kämmt. Dabei kann die Getriebestufe eine Übersetzung der Bewegungen des Betätigungsteiles vorsehen, um auch bei kleinen Möbelteilbewegungen eine ausreichende Dämpferbewegung zu erzielen.In a further development of the invention, the actuating part may be formed as an axially displaceable rack profile, which meshes with the seated on the damper gear. In this case, the transmission stage provide a translation of the movements of the operating part in order to achieve a sufficient damper movement even with small furniture part movements.

In besonders vorteilhafter Weise ist die Dämpfungsvorrichtung in eine Schließvorrichtung integriert. Das Betätigungsteil bzw. ein damit verbundenes Getriebeteil kann mit einer Feder in Schließrichtung beaufschlagt sein. Insbesondere kann vorgesehen sein, dass die Feder beim Öffnen des Möbelteils gespannt wird, wobei dies vorzugsweise beim anfänglichen Öffnen des Möbelteils erfolgt, sodann die Feder verriegelt wird und das Betätigungsteil von dem Möbelteil abkuppelt, um eine ungehinderte Bewegung über den restlichen Auszugsweg sicherzustellen. Wird der Möbelteil sodann wieder geschlossen, gelangt der Betätigungsteil mit dem Möbelteil wieder in Eingriff, die Feder wird entriegelt und der Möbelteil von der Feder in die geschlossene Stellung getrieben. Hierbei setzt die Dämpferwirkung der Dämpfungsvorrichtung ein.In a particularly advantageous manner, the damping device is integrated in a closing device. The actuating part or an associated transmission part can be acted upon by a spring in the closing direction. In particular, it may be provided that the spring is tensioned when opening the furniture part, wherein this is preferably the initial opening of the furniture part, then the spring is locked and the operating part of the furniture part uncouples to ensure unimpeded movement over the remaining excerpt. If the furniture part is then closed again, the operating part comes back into engagement with the furniture part, the spring is unlocked and the furniture part is driven by the spring into the closed position. Here, the damping effect of the damping device begins.

Figur 1 zeigt einen Möbelbeschlag in Form einer Schubladenführung 1. Eine im wesentlichen L-förmige Tragschiene 2 kann mit ihrem vertikalen Steg 3 über geeignete Befestigungsmittel beispielsweise in Form von Bohrungen 4 an einem Möbelkorpus befestigt werden. An dem horizontalen Steg 5 der Tragschiene 2 ist in nicht näher dargestellter, an sich bekannter Weise eine Schublade verschieblich gelagert.Figure 1 shows a furniture fitting in the form of a drawer guide 1. A substantially L-shaped mounting rail 2 can be fixed with its vertical web 3 via suitable fastening means, for example in the form of holes 4 on a furniture body. On the horizontal web 5 of the support rail 2, a drawer is slidably mounted in a manner not known per se, not shown.

Wie Figur 1 zeigt, ist an der Tragschiene 2 eine Schließvorrichtung 6 gelagert, die mit einem Mitnehmer 7 in üblicher Weise einen nicht gezeigten, an der Laufschiene oder der Schubladenzarge befestigten Zapfen einfängt und mit diesem zusammenwirkt.As Figure 1 shows, a locking device 6 is mounted on the support rail 2, which captures with a driver 7 in the usual way a not shown, attached to the running rail or the drawer pin and cooperates with this.

Die an der Tragschiene 2 befestigte Schließvorrichtung 6 umfasst eine längliche Tragplatte 8, die an dem horizontalen Steg 5 der Tragschiene 2 befestigt ist, sowie einen Deckel 9, der mit der Tragplatte 8 der Schließvorrichtung 6 über Bohrungen 10 sowie geeignete Befestigungszapfen 11 verbunden ist. Aus dem von der Tragplatte 8 und dem Deckel 9 gebildeten Gehäuse der Schließvorrichtung 6 ragt der Mitnehmer 7 heraus, der einerseits eine Querachse 12 aufweist, mit der er an einem Betätigungsteil in Form eines Schlittens 13 schwenkbar angelenkt ist, wobei der Schlitten 13 zwischen dem Deckel 9 und der Tragplatte 8 längsverschieblich geführt ist. Andererseits ist der Mitnehmer 7 mit einem Führungsteil in Form eines Führungszapfens 14 in einer kulissenartig ausgebildeten Führungsbahn 15 geführt, die sowohl im Deckel 9 als auch in der Tragplatte 8 ausgebildet ist. Wie Figur 3 zeigt, wird der Mitnehmer 7 über eine Feder 16 in eine Richtung vorgespannt, die der geschlossenen Stellung der Schublade entspricht. Die Feder 16 ist einerseits an einem Befestigungsarm an dem Mitnehmer 7 und andererseits an der Tragplatte 8 eingehängt.The attached to the support rail 2 closing device 6 comprises an elongated support plate 8 which is fixed to the horizontal web 5 of the support rail 2, and a cover 9 which is connected to the support plate 8 of the locking device 6 via holes 10 and suitable mounting pins 11. From the housing formed by the support plate 8 and the lid 9 of the locking device 6 projects out of the driver 7, on the one hand has a transverse axis 12, with which it is pivotally hinged to an actuating part in the form of a carriage 13, wherein the carriage 13 between the lid 9 and the support plate 8 is guided longitudinally displaceable. On the other hand, the driver 7 is guided with a guide part in the form of a guide pin 14 in a slot-like design guide track 15 which is formed both in the cover 9 and in the support plate 8. As Figure 3 shows, the driver 7 is biased by a spring 16 in a direction corresponding to the closed position of the drawer. The spring 16 is hooked on the one hand to a mounting arm on the driver 7 and on the other hand on the support plate 8.

Die Figuren 3 bis 6 zeigen den Mitnehmer 7 in einer mittleren Stellung zwischen einer Öffnungs- und einer Schließstellung.Figures 3 to 6 show the driver 7 in a middle position between an open and a closed position.

Der Schlitten 13, der nur einachsig beweglich ist, ist mit einem Zahnstangenprofil 17 versehen, das der Tragplatte 8 zugewandt ist. Im Bereich des Zahnstangenprofils 17 besitzt die Tragplatte 8 eine Ausnehmung sowie ein an der Tragplatte 8 befestigtes Dämpfergehäuse 18, das nach unten von der Tragplatte 8 vorspringt und einen Dämpfer 19 aufnimmt, der als Rotationsdämpfer ausgebildet ist. Die Rotationsachse 20 des Rotationsdämpfers 19 erstreckt sich dabei quer zur Laufrichtung des Schlittens 13, wobei der Rotationsdämpfer 19 quer von dem Zahnstangenprofil 17 versetzt ist. Der Dämpfer 19 kann an dem Dämpfergehäuse 18 befestigt sein.The carriage 13, which is only uniaxially movable, is provided with a rack profile 17, which faces the support plate 8. In the region of the rack profile 17, the support plate 8 has a recess and a fixed to the support plate 8 damper housing 18 which projects downwardly from the support plate 8 and a Damper 19 receives, which is designed as a rotary damper. The rotation axis 20 of the rotation damper 19 extends transversely to the running direction of the carriage 13, wherein the rotation damper 19 is offset transversely from the rack profile 17. The damper 19 may be attached to the damper housing 18.

Die Figuren 5 und 7 zeigen den Aufbau des Dämpfers 19 näher. Der Dämpfer 19 besitzt einen rotationssymmetrischen Mittelteil 21, dem sich beidseitig zwei vorspringende axial erstreckende und konzentrische Zylinder 21', 21", 41', 41" anschließen. Der Raum zwischen diesen Zylindern wird von komplementären, sich ebenfalls axial erstreckenden Zylindern 42, 43 beider Verankerungsteile 22 gefüllt, wobei zwischen den zugewandten Flächen ein kleiner Spalt verbleibt, in dem ein Fett hoher Viskosität die Dämpfungs- bzw. Bremskraft ausübt.Figures 5 and 7 show the structure of the damper 19 in more detail. The damper 19 has a rotationally symmetrical middle part 21, to which on both sides two projecting axially extending and concentric cylinders 21 ', 21 ", 41', 41" connect. The space between these cylinders is filled by complementary, also axially extending cylinders 42, 43 of both anchoring parts 22, wherein between the facing surfaces a small gap remains, in which a grease of high viscosity exerts the damping or braking force.

Die seitlichen Scheiben 22 weisen radial nach innen vorspringende Anschlagteile 23 auf, mit denen sie in nach oben freilaufenden Ausnehmungen 24 des Dämpfergehäuses 18 formschlüssig verankert werden.The lateral discs 22 have radially inwardly projecting stop members 23, with which they are positively anchored in upwardly free-running recesses 24 of the damper housing 18.

Das Getrieberad 26 sitzt auf der äußeren Wandung des Mittelteils 21 und ist im montierten Zustand in einer unteren Ausnehmung 44 des Gehäuses 18 enthalten, deren Wandung 44' seine axiale Bewegung begrenzt, wenn es außer Eingriff gebracht wird.The gear 26 is seated on the outer wall of the central portion 21 and is contained in the assembled state in a lower recess 44 of the housing 18, the wall 44 'limits its axial movement when it is disengaged.

Auf der äußeren Wandung 27 des Mittelteils 21 können ringförmige Nuten 45 zur Lagerung von O-Ringen 48 oder dergleichen vorgesehen sein, die die Aufgabe besitzen, einerseits die Reibung zwischen dem Getrieberad 26 und der Wandung 27 des Mittelteils zu verbessern und andererseits einen vorläufigen, stufenförmigen Gegenanschlag 46 derart zu bilden, dass das Getrieberad bis dann in seiner eingegriffenen Stellung fest gehalten ist, wenn keine neue Ausrückkraft an dieses durch die Schrägverzahnung ausgeübt wird.On the outer wall 27 of the central part 21 may be provided annular grooves 45 for the storage of O-rings 48 or the like, which have the task on the one hand to improve the friction between the gear 26 and the wall 27 of the middle part and on the other hand, a preliminary, step-shaped Counter stop 46 to be formed such that the gear until then held firmly in its engaged position when no new disengaging force is applied to this by the helical gearing.

Es versteht sich, dass anders ausgebildete Rotationsdämpfer Verwendung finden können.It is understood that differently shaped rotary damper can be used.

Unmittelbar auf dem drehbaren Teil des Dämpfers 19, das in der gezeichneten Ausführung von der äußeren Wandung des Mittelteils 21 gebildet wird, sitzt ein Getrieberitzel 26. Die äußere Wandung des Mittelteils 21 bildet eine Getriebeachse, auf der das Getrieberad 26 mit einer Innenausnehmung sitzt. Wie Figur 7 zeigt, sind die Außenmantelfläche 27 des drehbaren Dämpferteils sowie die Innenmantelfläche 28 des Getrieberitzels 26 jeweils konisch ausgebildet. Wird das Getrieberitzel 26 axial auf die konische Mantelfläche 27 des Dämpfers 19 geschoben, entsteht ein kraftschlüssiger, drehfester Eingriff, so dass eine Drehbewegung des Getrieberitzels 26 den Rotationsdämpfer mitdreht. Wird hingegen das Getrieberitzel 26 in entgegensetzter axialer Richtung bewegt, wird die konische Innenmantelfläche 28 von der konischen Außenmantelfläche 27 abgehoben, so dass das Getrieberitzel 26 keinen Dreheingriff mehr mit dem Dämpfer 19 hat. Die keilförmige Ausbildung der Außenmantelfläche des drehbaren Teils des Dämpfers 19 sowie die komplementär keilförmige Ausbildung der Innenmantelfläche 28 des Getrieberitzels 26 erlauben ein An- und Abkuppeln durch sehr kleine axiale Bewegungen des Getrieberitzels 26.Immediately on the rotatable part of the damper 19, which is formed in the illustrated embodiment of the outer wall of the central portion 21, sits a gear 26. The outer wall of the central portion 21 forms a transmission axis on which the gear 26 is seated with an inner recess. As Figure 7 shows, the outer circumferential surface 27 of the rotatable damper part and the inner circumferential surface 28 of the gear 26 are each formed conically. If the gear 26 is pushed axially onto the conical lateral surface 27 of the damper 19, a frictional, rotationally fixed engagement results, so that a rotational movement of the gear 26 rotates the rotary damper. If, however, the gear 26 is moved in the opposite axial direction, the conical inner surface 28 is lifted from the conical outer surface 27, so that the gear 26 has no turning engagement with the damper 19. The wedge-shaped design of the outer circumferential surface of the rotatable part of the damper 19 and the complementary wedge-shaped design of the inner circumferential surface 28 of the gear 26 allow a coupling and uncoupling by very small axial movements of the gear 26th

Die axiale Kupplungsbewegung des Getrieberitzels 26 der Getriebestufe 29 wird durch eine Schrägverzahnung 30 bewirkt, mittels derer das Getrieberitzel 26 mit dem Zahnstangenprofil 17 des Schlittens 13 kämmt. Wie Figur 6 zeigt, sind sowohl das Getrieberitzel 26 als auch das Zahnstangenprofil 17 schräg verzahnt, und zwar derart, dass bei Bewegungen der Getriebestufe 29 eine axiale Bewegung auf das Getrieberitzel 26 bewirkt wird, die beim Schließen der Schublade das Getrieberitzel 26 auf den Dämpfer 19 drückt und mit dessen drehbaren Teil verriegelt. Bei entgegengesetzter Bewegung, d.h. beim Öffnen der Schublade bewirkt die Schrägverzahnung 30 hingegen eine entgegengesetzte Bewegung des Getrieberitzels 26, die dieses von dem Dämpfer 19 abhebt und von dessen drehbaren Teil entriegelt. Das mit dem Dämpfer 19 verriegelbare und entriegelbare Getriebeelement 26 bildet eine in die Getriebestufe 29 integrierte Freilaufkupplung 31.The axial coupling movement of the gear 26 of the gear stage 29 is effected by a helical gear 30, by means of which the gear 26 meshes with the rack profile 17 of the carriage 13. As FIG. 6 shows, both the gear pinion 26 and the toothed rack profile 17 are helically toothed, in such a way that an axial movement is effected on the gear pinion 26 during movements of the gear stage 29, the gear pinion 26 on the damper 19 when the drawer is closed pushes and locks with its rotatable part. With opposite movement, i. when opening the drawer, however, the helical gear 30 causes an opposite movement of the gear 26, which lifts it from the damper 19 and unlocked from the rotatable part. The lockable with the damper 19 and unlocked gear member 26 forms an integrated into the gear stage 29 one-way clutch 31st

Sollte die rein kraftschlüssige Kupplung zwischen dem Getrieberitzel 26 und dem drehbaren Teil des Rotationsdämpfers 19 nicht ausreichend sein, können das Getrieberitzel 26 sowie der drehbare Mittelteil 21 des Dämpfers 19 jeweils komplementär zueinander ausgebildete, formschlüssig aneinandergreifende Passflächen besitzen. Wie Figur 8 zeigt, kann die insgesamt konisch ausgebildete Außenmantelfläche 27 des drehbaren Mittelteils 21 des Dämpfers 19 facettenartige bzw. keilförmige Abflachungen 32 besitzen. Die Innenmantelfläche 28 des Getrieberitzels 26 kann entsprechend insgesamt etwa konisch ausgebildet sein und dabei Abflachungen 33 besitzen, die zu den Abflachungen 32 des Mittelteils 21 komplementär und ebenfalls keilförmig angestellt sind. Wir das Getrieberitzel 26 auf die Außenmantelfläche 27 des Mittelteils 21 geschoben, gelangen die Abflachungen 32 und 33 miteinander in formschlüssigen Eingriff. Bei entgegengesetzter axialer Bewegung des Getrieberitzels 26 werden die Abflachungen 33 von den Abflachungen 32 abgehoben, so dass kein drehfester Eingriff zwischen dem drehbaren Dämpferteil und dem Getrieberitzel 26 mehr besteht.If the purely frictional coupling between the gear 26 and the rotatable part of the rotary damper 19 is not sufficient, the gear 26 and the rotatable middle part 21 of the damper 19 can each be complementary have mutually trained, mating mating mating surfaces. As FIG. 8 shows, the overall conically shaped outer circumferential surface 27 of the rotatable central part 21 of the damper 19 may have facet-shaped or wedge-shaped flattenings 32. The inner circumferential surface 28 of the gear 26 may be formed accordingly a total of approximately conical and thereby have flats 33 which are complementary to the flats 32 of the central portion 21 and also employed wedge-shaped. If we pushed the gear 26 on the outer circumferential surface 27 of the central part 21, the flats 32 and 33 engage with each other in positive engagement. In the opposite axial movement of the gear 26, the flats 33 are lifted from the flats 32, so that no rotationally fixed engagement between the rotatable damper part and the gear 26 is more.
