Description

Die vorliegende Erfindung betrifft eine Schließ- und Dämpfungsvorrichtung für bewegbare Möbelteile, insbesondere für an einem Möbel verschiebbare Schiebetüren gemäß dem Oberbegriff des Anspruchs 1 und dem Oberbegriff des Anspruchs 7.The present invention relates to a closing and damping device for movable furniture parts, in particular for sliding on a furniture sliding doors according to the preamble of claim 1 and the preamble of claim 7.

Derartige Schließ- und Dämpfungsvorrichtungen sind in zahlreichen Varianten aus dem Stand der Technik bekannt. Solche Schließ- und Dämpfungsvorrichtungen werden insbesondere bei Schiebetürmöbeln dazu eingesetzt, eine Schiebetür ab einer vorbestimmten Position selbsttätig in die Schließposition einzuziehen.Such closing and damping devices are known in numerous variants from the prior art. Such closing and damping devices are used in particular in sliding door furniture to move a sliding door from a predetermined position automatically in the closed position.

Vor allem wenn bei solchen Schließ- und Dämpfungsvorrichtungen als Kraftspeicher eine Zugfeder Verwendung findet, sind aufgrund der linearen Federkennlinie der Zugfeder beim Öffnen des bewegbaren Möbelteils, also zum Beispiel der Schiebetür, relativ hohe Betätigungskräfte erforderlich, um die Feder auf eine vorbestimmte Länge vorzuspannen.Especially if in such closing and damping devices as a power storage a tension spring is used, due to the linear spring characteristic of the tension spring when opening the movable furniture part, so for example the sliding door, relatively high actuating forces required to bias the spring to a predetermined length.

So ist aus der US2010/0229341 A1 eine Schließ- und Dämpfungsvorrichtung mit einem als Zugfeder ausgebildeten Kraftspeicher bekannt, bei der die Zugfeder mit einer drehbar mit einem Getrieberad gekoppelten Stange verbunden ist. Das Getrieberad selbst ist dabei mit einem Schlitten verbunden, der einen Fänger zwischen einer Auffangposition und einer zurückgezogenen Warteposition bewegt. Die Zugfeder dient dabei dazu, den Fänger nach Freigabe eines am bewegbaren Möbelteil befestigten Fangbolzens in die Warteposition zu bewegen.So is out of the US2010 / 0229341 A1 a closing and damping device with a force accumulator designed as a tension spring, in which the tension spring is connected to a rotatably coupled to a gear rod. The gear wheel itself is connected to a carriage which moves a catcher between a catching position and a retracted waiting position. The tension spring is used to move the catcher after release of a catch bolt attached to the movable furniture part in the waiting position.

Um die aufzuwendende Kraft beim Öffnen der Schiebetür möglichst gering zu halten bzw. die Steigung der Federkennlinie zu verringern, werden bei herkömmlichen Lösungen möglichst lange Zugfedern verwendet, die in einem Gehäuse umgelenkt werden. Alternativ ist auch der Einbau von mehreren kaskadierten Zug- und/oder Druckfedern bekannt.In order to minimize the force to be expended when opening the sliding door or to reduce the slope of the spring characteristic, as long as possible tension springs are used in conventional solutions, which are deflected in a housing. Alternatively, the installation of several cascaded tension and / or compression springs is known.

Aufgabe der vorliegenden Erfindung ist es, eine Schließ- und Dämpfungsvorrichtung für bewegbare Möbelteile bereitzustellen, bei der die für einen Öffnungsvorgang aufzuwendende Kraft nochmals geringer ist bzw. bei der die Steigung der Federkennlinie nochmals verringert wird.Object of the present invention is to provide a closing and damping device for movable furniture parts, in which the expended for an opening operation force is even lower or in which the slope of the spring characteristic is further reduced.

Diese Aufgabe wird mit einer Schließ- und Dämpfungsvorrichtung für bewegbare Möbelteile mit den Merkmalen des Anspruchs 1 sowie durch eine Schließ-und Dämpfungsvorrichtung für bewegbare Möbelteile mit den Merkmalen des Anspruchs 7 gelöst.This object is achieved with a closing and damping device for movable furniture parts with the features of claim 1 and by a closing and damping device for movable furniture parts with the features of claim 7.

Die erfindungsgemäße Schließ- und Dämpfungsvorrichtung weist einen an einem Gehäuse mit einem ersten Ende befestigten Kraftspeicher auf, insbesondere in Gestalt einer Zugfeder, der beim Öffnungsvorgang eines bewegbaren Möbelteils gespannt und dessen gespeicherte Kraft beim Schließvorgang als Einzugshilfe in die endgültige Schließstellung für das bewegbare Möbelteil genutzt wird. Des Weiteren weist die Schließ- und Dämpfungsvorrichtung eine Dämpfungseinrichtung auf, insbesondere in Gestalt einer pneumatischen oder hydraulischen Dämpfungsvorrichtung oder dergleichen. Der Kraftspeicher ist mit einer Umlenkvorrichtung mit einem Zahnrad, einer mit dem Zahnrad kämmenden Zahnstange und einer drehfest an dem Zahnrad angeordneten Halterung mit seinem zweiten Ende gekoppelt. Die Umlenkvorrichtung weist eine den Abstand des Drehpunktes des Zahnrades von dem Anlenkpunkt des Kraftspeichers während eines Öffnungs- oder Schließvorgangs verändernde Ablaufkurve auf. Die Ablaufkurve ist als spiralförmiges Auflager für den Kraftspeicher ausgebildet an der Halterung vorgesehen, wobei der Anlenkpunkt des Kraftspeichers in einer Schließposition maximal vom Drehpunkt des Zahnrades beabstandet ist.The closing and damping device according to the invention has a mounted on a housing with a first end of energy storage, in particular in the form of a tension spring tensioned during the opening process of a movable furniture part and its stored force is used during the closing process as Einziehshilfe in the final closed position for the movable furniture part , Furthermore, the closing and damping device has a damping device, in particular in the form of a pneumatic or hydraulic damping device or the like. The energy storage is coupled to a deflection device with a gear, meshing with the gear rack and a rotatably mounted on the gear holder with its second end. The deflecting device has a flow curve that changes the distance of the pivot point of the toothed wheel from the articulation point of the force accumulator during an opening or closing operation. The drainage curve is designed as a spiral bearing for the energy storage device provided on the holder, wherein the articulation point of the force accumulator is spaced in a closed position maximally from the pivot point of the gear.

Wird nun ein bewegbares Möbelteil, insbesondere eine Schiebetür gegenüber dem Möbel geöffnet, drückt ein Mitnehmer gegen eine Zahnstange, welche das Zahnrad antreibt und dabei den Kraftspeicher um diese Ablaufkurve aufwickelt. Bedingt durch die Formgestalt der Ablaufkurve ändert sich dabei der wirksame Hebelarm,des Anlenkpunktes des einen Kraftspeicherendes an dem Zahnrad. Dadurch ist im Vergleich zu herkömmlichen Lösungen die für einen Öffnungsvorgang aufzuwendende Kraft geringer und im Falle der Verwendung einer Zugfeder als Kraftspeicher gestaltet sich die Federkennlinie flacher, insbesondere sogar waagerecht oder leicht fallend.Now, if a movable furniture part, in particular a sliding door opens relative to the furniture, pushes a driver against a rack, which drives the gear and thereby wound up the energy storage to this flow curve. Due to the shape of the flow curve thereby changes the effective lever arm, the pivot point of a power storage end of the gear. As a result, the force to be expended for an opening operation is lower in comparison with conventional solutions, and in the case of the use of a tension spring as a force accumulator, the spring characteristic is flatter, in particular even horizontal or slightly falling.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer vorteilhaften Ausführungsvariante ist das an der Halterung befestigte Ende des Kraftspeichers als Seil- oder geradliniges Drahtstück ausgebildet. So kann eine einfachere Lagerung des Kraftspeichers auf der Halterung erreicht werden, da die Länge des Seil- oder geradlinigen Drahtstücks idealerweise so bemessen ist, dass nur das Seil- oder geradlinige Drahtstück in Kontakt mit der Halterung steht.According to an advantageous embodiment variant, the end of the force accumulator attached to the holder is designed as a cable or rectilinear piece of wire. Thus, a simpler storage of the energy accumulator can be achieved on the holder, since the length of the rope or straight wire piece is ideally dimensioned so that only the wire or straight wire piece is in contact with the holder.

Gemäß einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Schließ- und Dämpfungsvorrichtung ist das Zahnrad elliptisch und die Zahnstange in der Ebene senkrecht zur Drehachse des Zahnrades in einem Bereich, bei dem sie in einer Schließposition der Schließ- und Dämpfungsvorrichtung mit dem Zahnrad kämmt, breiter als in einem Bereich, bei dem die Zahnstange in einer Öffnungsposition der Schließ- und Dämpfungsvorrichtung mit dem Zahnrad kämmt. Eine solche Ausgestaltung des Zahnrads bzw. der Zahnstange bewirkt, dass das Rückdrehmoment des Kraftspeichers in der geschlossenen Stellung größer ist als in der Offenstellung des Zahnrades. Dadurch wird, wie bei der Aufwickeltechnik selbst, die große Kraft des gespannten Kraftspeichers kompensiert. Durch die bei dieser Ausführungsvariante verwirklichte Kombination von Aufwickeltechnik und Abwälzung der Verzahnung um eine Kurve ergibt sich nach den Hebelgesetzen ein maximaler Effekt hinsichtlich der Minimierung der beim Öffnungsvorgang erforderlichen Kraft.According to a further advantageous embodiment of the closing and damping device according to the invention, the gear is elliptical and the rack in the plane perpendicular to the axis of rotation of the gear in a region in which it meshes with the gear in a closed position of the closing and damping device, wider than in one Area where the rack meshes with the gear in an opening position of the closing and damping device. Such a configuration of the gear or the rack causes the return torque of the force accumulator in the closed position is greater than in the open position of the gear. As a result, as in the winding technique itself, the great force of the tensioned energy storage compensated. By realized in this embodiment combination of winding and rolling of the toothing around a curve results according to the leverage laws a maximum effect in terms of minimizing the force required during the opening process.

Gemäß einer weiteren vorteilhaften Ausführungsvariante ist die Schließ- und Dämpfungsvorrichtung so ausgebildet, dass der Kraftspeicher mit seinem ersten Ende derart an dem Gehäuse befestigt und mit seinem zweiten Ende an der Umlenkvorrichtung gekoppelt ist, dass der Kraftspeicher während eines Öffnungs- oder Schließvorgangs stets geradlinig zwischen seinen Enden gehalten ist. Dadurch wird erreicht, dass während eines Öffnungsvorgangs der Kraftspeicher mit fortschreitendem Öffnen des bewegbaren Möbelteils weniger stark gespannt und insbesondere bei Verwendung einer Zugfeder als Kraftspeicher diese weniger stark ausgezogen wird als um die Distanz, um die die Zahnstange verschoben wird beziehungsweise weniger stark ausgezogen wird als bei der Umlenkung oder Aufwicklung des Kraftspeichers. Auch bei dieser Ausführungsvariante ist die für einen Öffnungsvorgang aufzuwendende Kraft geringer und insbesondere die Federkennlinie flacher als bei herkömmlichen Lösungen.According to a further advantageous embodiment variant, the closing and damping device is designed such that the energy accumulator is fixed with its first end to the housing and coupled with its second end to the deflecting device, that the energy storage during an opening or closing process always straight between his Ends is held. This ensures that during an opening process of the energy storage with progressing opening of the movable furniture part less tense and especially when using a tension spring as a force storage this is less pronounced than the distance to which the rack is moved or pulled out less than at the deflection or winding of the energy storage. Also in this embodiment, the expended for an opening operation force is lower and in particular the spring characteristic flatter than in conventional solutions.

These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

In der Figur 3 ist mit dem Bezugszeichen 1 insgesamt eine Ausführungsvariante einer erfindungsgemäßen Schließ- und Dämpfungsvorrichtung für bewegbare Möbelteile, insbesondere für an einem in den Figuren 6 und 7 gezeigten Möbel 12 verschiebbare Schiebetüren 15 bezeichnet. Die Schließ- und Dämpfungsvorrichtung 1 weist dabei, wie auch in den Figuren 1 und 2 zu erkennen ist, einen Mitnehmer 4 auf, in dem im montierten Zustand der Schließ- und Dämpfungsvorrichtung 1 an einem Möbelkorpus 12 ein an einer Schiebetür 15 angeordneter Aktivator eingreift, der beim Öffnen der Schiebetür 15 den Mitnehmer 4 entlang eines Führungsschlitzes 23, 33 in dem Gehäuse 2, 3 der Schließ- und Dämpfungsvorrichtung 1 verschiebt und dabei einen an dem Gehäuse 2, 3 mit einem ersten Ende 61 befestigten Kraftspeicher 6, welcher vorzugsweise als Zugfeder ausgebildet ist, streckt. Dieser Kraftspeicher 6, welcher beim Öffnungsvorgang des bewegbaren Möbelteils, beispielsweise der in Figur 7 gezeigten Schiebetür 15, gespannt wird und dessen dabei gespeicherte Kraft beim späteren Schließvorgang der Schiebetür als Einzugshilfe in die endgültige Schließstellung der Schiebetür 15 genutzt wird, ist an seinem anderen Ende 62 mit einer Umlenkvorrichtung 5 gekoppelt, die im Wesentlichen aus einem Zahnrad 52, einer mit dem Zahnrad 52 kämmenden Zahnstange 51 und einer drehfest an dem Zahnrad 52 angeordneten Halterung 53 besteht.In the FIG. 3 is the reference numeral 1 a total of a variant of a closing and damping device according to the invention for movable furniture parts, in particular for at one in the FIGS. 6 and 7 Furniture shown 12 sliding sliding doors 15 referred. The closing and damping device 1 has, as well as in the FIGS. 1 and 2 can be seen, a driver 4, in which engages in the mounted state of the closing and damping device 1 on a furniture body 12 arranged on a sliding door 15 activator, the driver 4 when opening the sliding door 15 along a guide slot 23, 33 in the Housing 2, 3 of the closing and damping device 1 shifts while a fixed to the housing 2, 3 with a first end 61 of energy storage device 6, which is preferably designed as a tension spring stretches. This energy storage 6, which during the opening process of the movable furniture part, for example, the in FIG. 7 shown sliding door 15 is tensioned and its stored power is used during subsequent closing operation of the sliding door as a retraction aid in the final closed position of the sliding door 15 is coupled at its other end 62 with a deflection device 5, which consists essentially of a gear 52, one with the toothed wheel 52 meshing rack 51 and a non-rotatably mounted on the gear 52 holder 53 consists.

Die Figur 4 zeigt die Schließ- und Dämpfungsvorrichtung 1 in ihrer Schließstellung, die Figur 5 in ihrer Öffnungsstellung, nachdem der von der Schiebetür 15 befestigte Aktivator außer Eingriff mit dem Mitnehmer 4 steht. In der in Figur 4 gezeigten Schließstellung ist der Kraftspeicher 6 im Wesentlichen entspannt. Dazu steht die Halterung 53 der Umlenkvorrichtung 5 in einer Position, bei der das an der Halterung 53 befestigte Ende 62 des Kraftspeichers 6 noch eine Umlenkung erfahren kann. Sobald die Schiebetür 15 geöffnet wird, drückt der Mitnehmer 4 über eine Kupplung 8 gegen die Zahnstange 51.The FIG. 4 shows the closing and damping device 1 in its closed position, the FIG. 5 in its open position, after the attached by the sliding door 15 activator is out of engagement with the driver 4. In the in FIG. 4 shown closed position of the energy storage 6 is substantially relaxed. For this purpose, the holder 53 of the deflection device 5 is in a position in which the attached to the holder 53 end 62 of the energy accumulator 6 can still undergo a deflection. As soon as the sliding door 15 is opened, the driver 4 presses against the rack 51 via a coupling 8.

Das vordere Ende der Zahnstange 51 ist dabei mit einer Verzahnung 511 versehen, die mit den Zähnen des Zahnrades 52 kämmt. Durch die Verschiebung der Zahnstange 51 (in den Figuren 4 und 5 nach rechts) wird das Zahnrad 52 und damit auch die drehfest an dem Zahnrad 52 befestigte Halterung 53 im Uhrzeigersinn gedreht und damit der Kraftspeicher 6 derart umgelenkt und gespannt, dass sich der Abstand des Drehpunktes 521 des Zahnrades 52 gegenüber der Anlenkung des Kraftspeichers 6 während des Öffnungsvorgangs verändert, insbesondere während des Öffnungsvorgangs verkleinert. Durch die Verkleinerung dieses Abstandes verringert sich auch der Hebelarm und damit die aufzuwendende Kraft für die weitere Spannung des Kraftspeichers 6.The front end of the rack 51 is provided with a toothing 511 which meshes with the teeth of the gear 52. By the displacement of the rack 51 (in the FIGS. 4 and 5 to the right), the gear 52 and thus also the non-rotatably attached to the gear 52 holder 53 is rotated clockwise and thus the power storage 6 is deflected and tensioned so that the distance of the pivot point 521 of the gear 52 against the articulation of the energy accumulator 6 during the Opening operation changed, especially reduced during the opening process. By the Reduction of this distance also reduces the lever arm and thus the expended force for the further tension of the energy accumulator. 6

Durch die so bewirkte Reduzierung des Widerstands beim Öffnen der Schiebetür ist ein harmonischer Übergang der Schiebetür während der Öffnungsbewegung von einem Zustand, bei dem der Mitnehmer 4 mit dem Aktivator der Schiebetür im Eingriff steht, in den freigegebenen Zustand der Schiebetür gegeben. Bei den aus dem Stand der Technik bekannten Lösungen gibt es hier einen sprunghaften Abfall des Widerstandes beim Verlassen des Aktivators aus dem Eingriff mit dem Mitnehmer 4.By thus reducing the resistance in opening the sliding door, a smooth transition of the sliding door during the opening movement from a state where the driver 4 is engaged with the activator of the sliding door is given to the released state of the sliding door. In the case of the solutions known from the prior art, there is a sudden drop in the resistance on leaving the activator from engagement with the driver 4.

Die Halterung 53 ist gemäß der in den Figuren 1 bis 4 gezeigten Ausführungsvariante so an dem Zahnrad 52 befestigt, dass der Kraftspeicher bei der Aufwicklung auf die Halterung 53 auf einem spiralförmigen Auflager 531 aufliegt. Diese Spirale ist dabei so orientiert, dass der Abstand des Auflagers 531 in der Schließposition der des Zahnrades 52 bzw. der Halterung 53 maximal vom Drehpunkt 521 des Zahnrades 52 beabstandet ist und sich mit fortschreitender Aufwicklung des Kraftspeichers 6 auf die Halterung 53 dieser Abstand verringert.The holder 53 is according to the in the FIGS. 1 to 4 embodiment shown attached to the gear 52 so that the energy storage rests on the holder 53 on a spiral support 531 during the winding. This spiral is oriented so that the distance of the support 531 in the closed position of the gear 52 and the holder 53 is maximally spaced from the pivot point 521 of the gear 52 and decreases with progressive winding of the energy accumulator 6 on the holder 53 this distance.

Die Schließ- und Dämpfungsvorrichtung 1 weist des Weiteren eine Dämpfungseinrichtung 7 auf, die insbesondere als pneumatische oder hydraulische Dämpfungsvorrichtung ausbildet ist, wobei ein Stößel 71 mit einem Ende in das Dämpfungsvorrichtungsgehäuse dicht verschlossen hineinragt und mit dem anderen Ende an dem Gehäuse 2 oder 3 der Schließ- und Dämpfungsvorrichtung 1 festgelegt ist. Das Gehäuse der Dämpfungseinrichtung 7 ist dabei an die Zahnstange 51 angekoppelt und wird beim Verschieben des Mitnehmers 4 entlang eines Führungsschlitzes 24, 34 im Gehäuse 2, 3 der Schließ- und Dämpfungsvorrichtung 1 mitgeführt. Die Führung der Zahnstange 51 in den Führungsschlitzen 24, 34 des Gehäuses 2, 3 der Schließ- und Dämpfungsvorrichtung 1 erfolgt dabei vorzugsweise über zwei in die Führungsschlitze 24, 34 eingreifende Führungsstifte 513, welche an der Zahnstange 51 angeformt oder befestigt sind.The closing and damping device 1 further comprises a damping device 7, which is formed in particular as a pneumatic or hydraulic damping device, wherein a plunger 71 with one end in the damping device housing protrudes tightly and with the other end to the housing 2 or 3 of the closing - And damping device 1 is fixed. The housing of the damping device 7 is coupled to the rack 51 and is carried along the displacement of the driver 4 along a guide slot 24, 34 in the housing 2, 3 of the closing and damping device 1. The guide of the rack 51 in the guide slots 24, 34 of the housing 2, 3 of the closing and damping device 1 is preferably carried out via two engaging in the guide slots 24, 34 guide pins 513, which are integrally formed or fixed to the rack 51.

Die beiden Gehäuseteile 2, 3 der Schließ- und Dämpfungsvorrichtung 1 werden vorzugsweise miteinander verschraubt. Dazu sind an den vier Ecken des vorzugsweise rechteckig ausgebildeten Gehäuses 2, 3 Gewindeöffnungen vorgesehen, in die Schrauben 11 einschraubbar sind und so die beiden Gehäusehälften 2 und 3 miteinander verbinden. Über zwei weitere Öffnungen 25, 35 im Gehäuse 2, 3 ist die Schließ- und Dämpfungsvorrichtung 1 an einem Möbel anschraubbar.The two housing parts 2, 3 of the closing and damping device 1 are preferably screwed together. For this purpose, at the four corners of the preferably rectangular housing 2, 3 threaded openings provided in the screws 11 are screwed and so the two Connect housing halves 2 and 3 together. About two further openings 25, 35 in the housing 2, 3, the closing and damping device 1 can be screwed to a piece of furniture.

Die Figuren 6 und 7 zeigen die Schließ- und Dämpfungsvorrichtung 1 in an einem Möbel befestigten Zustand. Gezeigt ist hier ein Ausschnitt eines Schiebetürenschrankes mit einer Schiene 13, in der eine Schiebetür 15 über eine Rollvorrichtung 16 verschiebbar eingehängt ist, wobei die Rollvorrichtung 16 in der Schließstellung der Schiebetür 15 in einem Arretierelement 14 am Ende der Schiene 13 festlegbar ist.The FIGS. 6 and 7 show the closing and damping device 1 in a state attached to a furniture. Shown here is a section of a sliding door cabinet with a rail 13, in which a sliding door 15 is slidably mounted via a rolling device 16, wherein the rolling device 16 in the closed position of the sliding door 15 in a locking element 14 at the end of the rail 13 can be fixed.

In den Figuren 8 bis 11 ist eine weitere Ausführungsvariante einer nicht erfindungsgemäßen Schließ- und Dämpfungsvorrichtung 1 gezeigt. Hier ist die Halterung 53 nicht mit einem spiralförmigen Auflager versehen, sondern im Wesentlichen als kreisförmige Scheibe ausgebildet, von der sich eine Haltezunge 532 radial erstreckt, an der das zweite Ende 62 des Kraftspeichers 6 befestigt ist. Diese Befestigung des Kraftspeichers 6 an der Umlenkvorrichtung 5 ist bevorzugt drehbar ausgeführt, und zwar zu einer parallel zur Drehachse 521 des Zahnrads 52 orientierten Drehachse.In the FIGS. 8 to 11 a further embodiment of a non-inventive closing and damping device 1 is shown. Here, the holder 53 is not provided with a spiral bearing, but substantially formed as a circular disc, from which a retaining tongue 532 extends radially, to which the second end 62 of the force accumulator 6 is attached. This attachment of the force accumulator 6 to the deflection device 5 is preferably rotatable, namely to a parallel to the axis of rotation 521 of the gear 52 oriented axis of rotation.

Wie anhand der Figuren 10 und 11 zu erkennen ist, wird bei einer Bewegung der Schließ- und Dämpfungsvorrichtung aus einer Schließstellung in die geöffnete Stellung beim Verschieben des Mitnehmers 4 mittels des Kupplungsstückes 8 an der mit dem Zahnrad 52 kämmenden Zahnstange 51 der gesamte Kraftspeicher 6 um den Aufhängepunkt des Kraftspeichers am ersten Ende 61 des Kraftspeichers 6 nach unten geschwenkt. Dadurch wird erreicht, dass der bevorzugt als Zugfeder ausgebildete Kraftspeicher 6 nicht um die gesamte Distanz ausgelenkt wird, um die die Zahnstange 51 verschoben wird, sondern um eine geringere Distanz, da der Kraftspeicher 6 mit seinem zweiten Ende 62, mit dem dieser an der Halterung 53, insbesondere an der radial nach außen stehenden Haltezunge 532 festgelegt ist, eine Drehbewegung und nicht eine Linearverschiebung ausführt.As based on the FIGS. 10 and 11 can be seen, in a movement of the closing and damping device from a closed position to the open position when moving the driver 4 by means of the coupling piece 8 on the meshing with the gear rack 52 51 of the entire energy storage 6 to the suspension point of the energy storage at the first end 61 of the energy storage device 6 pivoted downward. This ensures that the force accumulator 6, which is preferably designed as a tension spring, is not deflected by the entire distance about which the rack 51 is displaced, but by a smaller distance, since the energy accumulator 6 has its second end 62, with which it bears against the holder 53, in particular fixed to the radially outward retaining tongue 532, performs a rotational movement and not a linear displacement.

In den Figuren 12 und 13 ist eine weitere Ausführungsvariante der erfindungsgemäßen Schließ- und Dämpfungsvorrichtung 1 gezeigt. Hier ist der Kraftspeicher 6 im Gegensatz zu der in den Figuren 1 bis 4 beschriebenen Ausführungsvariante nicht vollständig als Zugfeder ausgebildet, sondern im Bereich des mit der Halterung 53 in Wirkverbindung stehenden Bereiches als Seil- oder geradliniges Drahtstück 63, welches bei der Bewegung der Zahnstange 51 von der Schließstellung in die Öffnungsstellung (Figur 13) auf der Halterung 53 aufgewickelt wird.In the FIGS. 12 and 13 a further embodiment of the closing and damping device 1 according to the invention is shown. Here is the energy storage 6 in contrast to the in the FIGS. 1 to 4 embodiment variant described not completely formed as a tension spring, but in the area of the holder 53 in operative connection with the area as rope or straight piece of wire 63, which in the movement of the rack 51 from the closed position to the open position ( FIG. 13 ) is wound on the holder 53.

Als weitere in den Figuren 19 und 20 gezeigte Alternative ist der Kraftspeicher 6 im Bereich des mit der Halterung 53 in Wirkverbindung stehenden Bereiches als Bandstück 64 ausgebildet, welches wie bei der anhand der Figuren 12 und 13 beschriebenen Ausführungsvariante bei der Bewegung der Zahnstange 51 von der Schließstellung in die Öffnungsstellung (Figur 13) auf der Halterung 53 aufgewickelt wird. Das Bandstück 64 ist dabei insbesondere als Kunststoff-Filmscharnier-artiges Bauteil ausgebildet, denkbar ist aber auch ein Gewebeband aus Kunststoff, Textil oder dünnem Metall. Das Bandstück 64 ist dabei bevorzugt als separates Bauteil ausgebildet, welches einerseits an der Halterung 53 des Zahnrads 52 angeschlagen ist und andererseits an dem Kraftspeicher 6.As more in the Figures 19 and 20 As shown alternative, the energy accumulator 6 is formed in the region of the region in operative connection with the holder 53 as a piece of tape 64, which, as in the case of FIG FIGS. 12 and 13 described embodiment in the movement of the rack 51 from the closed position to the open position ( FIG. 13 ) is wound on the holder 53. The piece of tape 64 is designed in particular as a plastic film hinge-like component, but it is also conceivable a fabric tape made of plastic, textile or thin metal. The piece of tape 64 is preferably formed as a separate component, which is struck on the one hand on the holder 53 of the gear 52 and on the other hand on the energy storage. 6

In den Figuren 15 bis 18 ist eine nochmals weitere vorteilhafte Ausgestaltung der erfindungsgemäßen Schließ- und Dämpfungsvorrichtung 1 gezeigt. Hier ist im Gegensatz zu den vorangegangenen Ausführungsbeispielen das Zahnrad 52 nicht kreisrund, sondern elliptisch geformt. Entsprechend ist auch die Zahnstange, genauer der mit der Verzahnung versehene Bereich 511 der Zahnstange 51 schräg geformt. Das heißt, dass die Zahnstange 51 in der Ebene senkrecht zur Drehachse 521 des Zahnrades 52 in einem Bereich, bei dem sie in eine Schließposition der Schließ- und Dämpfungsvorrichtung 1 mit dem Zahnrad 52 kämmt, breiter ist als in einem Bereich, bei dem die Zahnstange 51 in einer Öffnungsposition der Schließ- und Dämpfungsvorrichtung mit dem Zahnrad 52 kämmt.In the FIGS. 15 to 18 is shown yet another advantageous embodiment of the closing and damping device 1 according to the invention. Here, in contrast to the preceding embodiments, the gear 52 is not circular, but elliptical. Accordingly, the rack, more precisely provided with the toothing portion 511 of the rack 51 is obliquely shaped. That is, the rack 51 is wider in the plane perpendicular to the rotational axis 521 of the gear 52 in a region where it meshes with the gear 52 in a closing position of the closing and damping device 1, than in a region where the rack 51 meshes with the gear 52 in an opening position of the closing and damping device.

Figur 14 zeigt anschaulich einen Vergleich eines Kraft-Weg-Verlaufs einer herkömmlichen Schließvorrichtung, auch Selbsteinzug genannt, gemäß dem Stand der Technik (Kennlinie A) im Vergleich zu einem Kraft-Weg-Verlauf einer erfindungsgemäßen Schließ- und Dämpfungsvorrichtung 1 (Kennlinie B). Deutlich ist bei der Kennlinie B zu sehen, dass mit zunehmender Auslenkung s die zur Auslenkung benötigte Kraft F stetig abfällt, während bei einer herkömmlichen Schließ- und Dämpfungsvorrichtung, wie sie durch die Kennlinie A dargestellt ist, mit zunehmender Auslenkung s der Zugfeder auch eine größere Kraft F aufzuwenden ist. FIG. 14 clearly shows a comparison of a force-displacement curve of a conventional locking device, also called Selbsteinzug, according to the prior art (characteristic A) in comparison to a force-displacement curve of a closing and damping device 1 according to the invention (curve B). It can clearly be seen in the characteristic curve B that with increasing deflection s the force F required for the deflection decreases steadily, while with a conventional closing and damping device, as represented by the characteristic A, with increasing deflection s of the tension spring also a larger one To spend force F is.
