Description

Einzugsvorrichtung für Möbelteile  Feeding device for furniture parts
Die vorliegende Erfindung bezieht sich auf eine Einzugsvorrichtung zum Einziehen eines bewegbar gelagerten Möbelteiles in die geschlossene Endlage relativ zu einem Möbelkorpus, umfassend: The present invention relates to a collection device for drawing a movably mounted furniture part in the closed end position relative to a furniture body, comprising:
- einen Mitnehmer, der mit dem bewegbaren Möbelteil lösbar koppelbar ist und der zumindest abschnittsweise entlang eines linearen Verfahrweges verschiebbar gelagert ist,  a driver, which is releasably coupled to the movable furniture part and which is at least partially slidably mounted along a linear travel path,
- wenigstens eine Federvorrichtung zur Kraftbeaufschlagung des Mitnehmers, wobei die Federvorrichtung über einen vom Mitnehmer gesonderten - At least one spring device for applying force to the driver, wherein the spring device via a separate from the driver
Federhalter spannbar ist, Spring holder is tensioned,
- eine Koppelvorrichtung zur Bewegungskopplung zwischen Mitnehmer und Federhalter, wobei durch die Koppelvorrichtung die Befestigungsstelle der Federvorrichtung am Federhalter beim Ausziehen des Mitnehmers entlang einer Steuerkurve gegenüber der Position des verfahrenden Mitnehmers zurückfällt.  - A coupling device for movement coupling between the driver and the spring holder, which falls back by the coupling device, the attachment point of the spring device on the spring holder when pulling out the driver along a control cam with respect to the position of the traversing driver.
Im Weiteren betrifft die Erfindung eine Schubladenausziehführung mit einer Einzugsvorrichtung der zu beschreibenden Art sowie eine Anordnung mit einer Schublade und mit einer derartigen Einzugsvorrichtung. Furthermore, the invention relates to a drawer pull-out with a collection device of the type to be described and an arrangement with a drawer and with such a collection device.
Einzugsvorrichtungen kommen insbesondere mit Schubladen oder Schiebetüren zum Einsatz, die über einen Großteil ihres Auszugsbereiches frei verfahrbar sind und die erst gegen Ende der Schließbewegung vom Mitnehmer der Einzugsvorrichtung erfasst, durch Federkraft in die geschlossene Endlage eingezogen und dort mit einer vorgegebenen Schließkraft gehalten werden. Beim Öffnen des bewegbaren Möbelteiles muss ein Benutzer zunächst durch Ziehen eine Kraft entgegen des Federwiderstandes der Einzugsvorrichtung aufbringen, bis der Mitnehmer nach einer vorgegebenen Wegstrecke vom bewegbaren Möbelteil entkoppelt und in eine vorgespannte Parkposition bewegt wird, in der die Feder in einer gespannten Bereitschaftsposition verharrt, sodass das bewegbare Möbelteil beim nächsten Schließvorgang erneut eingezogen werden kann. Für einen Benutzer macht sich die Entkopplung des Mitnehmers bei der Öffnungsbewegung der Schublade häufig mit einer ruckartigen Bewegung und einem Klickgeräusch bemerkbar, da infolge der plötzlichen Federabrisskraft die Schublade frei beweglich ist und aufgrund der zuvor ausgeübten Zugkraft in Öffnungsrichtung beschleunigt wird. Feeding devices are used, in particular, with drawers or sliding doors, which are freely movable over a large part of their pull-out area and which are only caught by the catch of the collection device towards the end of the closing movement, pulled into the closed end position by spring force and held there with a predetermined closing force. When opening the movable furniture part, a user must first apply by pulling a force against the spring resistance of the feeder until the driver is decoupled after a predetermined distance from the movable furniture part and moved to a preloaded parking position in which the spring remains in a cocked standby position, so the movable furniture part can be retracted again during the next closing process. For a user, the decoupling of the driver during the opening movement of the drawer often makes a jerky movement and a clicking sound noticeable, as a result of sudden spring-breaking force, the drawer is freely movable and is accelerated in the opening direction due to the previously applied tensile force.
Die WO 201 1/150432 A1 der Anmelderin löst dieses Problem durch einen vom Mitnehmer gesonderten Federhalter, welcher entlang einer Steuerkurve verschiebbar geführt ist. Der Mitnehmer und der Federhalter sind dabei durch eine Koppelvorrichtung in Form von ineinander greifenden Verzahnungen miteinander bewegungsgekoppelt verbunden. Beim Spannen der Federvorrichtung (d.h. beim Öffnen des bewegbaren Möbelteiles) fällt die Befestigungsstelle der Federvorrichtung am Federhalter gegenüber der Position des sich in Öffnungsrichtung verfahrenden Mitnehmers zurück, sodass die Bewegung der Befestigungsstelle der Federvorrichtung langsamer als die Bewegung des Mitnehmers ist. Das Aufladen der Federvorrichtung erfolgt dadurch mit einem reduzierten Kraftaufwand, der unerwünschte Federabriss und eine damit verbundene, übermäßige Beschleunigung des bewegbaren Möbelteiles beim Entkuppeln des Mitnehmers kann damit verhindert werden. Applicant's WO 201 1/150432 A1 solves this problem by means of a spring holder which is separate from the driver and which is displaceably guided along a control cam. The driver and the spring holder are connected by a coupling device in the form of interlocking gears coupled to each other. When the spring device is tensioned (i.e., when the movable furniture part is opened), the attachment point of the spring device on the spring retracts from the position of the follower in the opening direction, so that the movement of the attachment point of the spring device is slower than the movement of the follower. The charging of the spring device is characterized with a reduced effort, the unwanted spring break and an associated, excessive acceleration of the movable furniture part when uncoupling the driver can be prevented.
Aufgabe der vorliegenden Erfindung ist es, eine Einzugsvorrichtung der eingangs erwähnten Gattung mit reduzierten Reibungskräften und einer kompakteren Bauweise anzugeben. Object of the present invention is to provide a collection device of the type mentioned with reduced frictional forces and a more compact design.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen angegeben. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.
Gemäß der Erfindung ist also vorgesehen, dass die Koppelvorrichtung wenigstens einen zweiarmigen Hebel mit zwei Hebelenden aufweist, wobei der zweiarmige Hebel um eine Drehachse am Federhalter schwenkbar gelagert ist, wobei ein erstes Hebelende des zweiarmigen Hebels mit dem Mitnehmer bewegungsgekoppelt verbunden ist und wobei das zweite Hebelende des zweiarmigen Hebels zumindest ein Führungselement aufweist, welches beim Ausziehen des Mitnehmers zumindest abschnittsweise entlang der Steuerkurve verschiebbar geführt ist. Durch die Koppelvorrichtung mit dem zweiarmigen Hebel kann ein Hebelgetriebe mit einer Kraftabsenkmechanik realisiert werden, welches reduzierte Reibungskräfte und reduzierte Geräuschentwicklungen im Vergleich zu einem Zahnradgetriebe aufweist. Neben einfacher auszuführenden Bauteilen bietet die vorgeschlagene Konstruktion auch die Möglichkeit, die Hebel der Koppelvorrichtung - insbesondere in der eingezogenen Stellung des Mitnehmers - ineinander zu verschachteln, wodurch eine sehr kompakte Bauform der Einzugsvorrichtung realisierbar ist. Durch die jeweilige Form und Größe des zweiarmigen Hebels bzw. jene der Steuerkurve können die zum Spannen der Federvorrichtung erforderlichen Kräfte sowie die effektive Länge des Spannweges in vielen Ausführungsformen modifiziert werden. According to the invention, it is thus provided that the coupling device has at least one two-armed lever with two lever ends, wherein the two-armed lever is pivotally mounted about an axis of rotation on the spring holder, wherein a first end of the lever Hebelarm of the two-arm is coupled for movement with the driver and wherein the second end of the lever of the two-armed lever has at least one guide element which is guided at least partially displaceable along the control cam when pulling out of the driver. By the coupling device with the two-armed lever, a lever mechanism can be realized with a Kraftabsenkmechanik, which has reduced frictional forces and reduced noise compared to a gear transmission. In addition to simpler to perform components, the proposed construction also offers the possibility of the levers of the coupling device - especially in the retracted position of the driver - to nest together, creating a very compact design of the feeder can be realized. Due to the respective shape and size of the two-armed lever or those of the control cam, the forces required for tensioning the spring device and the effective length of the tensioning path can be modified in many embodiments.

Such a full extension is present when the rear wall 8 in the fully extended state of the drawer 4 is approximately flush with the end face of the furniture body 2.
Fig. 2 zeigt die Schubladenausziehführung 10 mit einer Einzugsvorrichtung 14 in einer perspektivischen Darstellung. Durch die Einzugsvorrichtung 14 ist die verschiebbar gelagerte Ausziehschiene 12 gegen Ende der Schließbewegung durch die Kraft einer Federvorrichtung 16 in die vollständige Endlage einziehbar. Die Ausziehschiene 12 weist hierfür üblicherweise ein (nicht gezeigtes) Koppelelement (insbesondere einen von der Ausziehschiene 12 abstehenden Zapfen) auf. Dieses Koppelelement ist mit einem relativ zum Gehäuse 17 verschiebbar gelagerten Mitnehmer 18 der Einzugsvorrichtung 14 lösbar koppelbar und kann anschließend durch die Kraft der Federvorrichtung 16 in die vollständige Endlage eingezogen werden. Das Gehäuse 17 der Einzugsvorrichtung 14 ist vorzugsweise an der Korpusschiene 1 1 befestigt und in einem zwischen der Ausziehschiene 12 und dem Befestigungsabschnitt 13 der Korpusschiene 1 1 gebildeten Zwischenraum angeordnet. Fig. 3 zeigt die Einzugsvorrichtung 14 in einer von oben her gesehenen Explosionsdarstellung. Zur gleitenden Führung des Mitnehmers 18 ist am Gehäuse 17 ein linearer Verfahrweg 19 vorgesehen, an welchen sich ein abgebogener oder abgekanteter Abschnitt 20 anschließt. Der Mitnehmer 18 weist eine Kerbe 27 auf, die mit einem an der Ausziehschiene 12 befestigten Koppelelement (insbesondere einem Zapfen) lösbar koppelbar ist. In der vollständigen Schließstellung der Schublade 4 befindet sich das Koppelelement in Eingriff mit der Kerbe 27. Beim manuellen Öffnen der Schublade 4 wird über das Koppelelement auch der Mitnehmer 18 entlang des linearen Verfahrweges in Öffnungsrichtung 35 (Fig. 5a-5d) gezogen, wodurch die Federvorrichtung 16 gespannt wird. Nach einer vorgegebenen Wegstrecke gelangt der Mitnehmer 18 in den abgebogenen Abschnitt 20, sodass der Mitnehmer 18 verschwenkt, das Koppelelement der Ausziehschiene 12 freigegeben und anschließend die Schublade 4 ungekoppelt weiter in Öffnungsrichtung 35 verfahrbar ist. Der Mitnehmer 18 verbleibt einstweilen im abgebogenen Abschnitt 20 in einer gekippten Lage, d.h. in einer vorgespannten, selbsthemmend arretierten Bereitschaftsposition, wobei die Federvorrichtung 16 gespannt ist. Beim Schließen der Schublade 4 kann das an der Ausziehschiene 12 angeordnete Koppelelement den Mitnehmer 18 durch den Eintritt in die Kerbe 27 wieder aus der vorgespannten Bereitschaftsposition herauslösen, woraufhin der Mitnehmer 18 (und damit die Ausziehschiene 12) durch die Kraft der Federvorrichtung 16 in die vollständige Schließstellung einziehbar ist. 2 shows the drawer pull-out guide 10 with a draw-in device 14 in a perspective view. By the collection device 14, the sliding mounted extractor rail 12 is retractable towards the end of the closing movement by the force of a spring device 16 in the full end position. For this purpose, the pull-out rail 12 usually has a coupling element (not shown) (in particular a pin projecting from the pull-out rail 12). This coupling element is releasably coupled with a relative to the housing 17 slidably mounted driver 18 of the retraction device 14 and can then be retracted by the force of the spring device 16 in the full end position.

Fig. 3 shows the collection device 14 in an exploded view from above. For sliding guidance of the driver 18, a linear travel path 19 is provided on the housing 17, to which a bent or bevelled portion 20 connects. The driver 18 has a notch 27 which is releasably coupled to a coupling element (in particular a pin) attached to the pull-out rail 12. In the complete closed position of the drawer 4, the coupling element is in engagement with the notch 27. When manually opening the drawer 4 is also pulled over the coupling element of the driver 18 along the linear travel in the opening direction 35 (Fig. 5a-5d), whereby the Spring device 16 is tensioned. After a predetermined Distance traveled by the driver 18 in the bent portion 20, so that the driver 18 is pivoted, the coupling element of the pull 12 released and then the drawer 4 is uncoupled further in the opening direction 35 movable. The driver 18 remains temporarily in the bent portion 20 in a tilted position, ie in a prestressed, self-locking arrested standby position, wherein the spring device 16 is tensioned. When closing the drawer 4 arranged on the pull-out rail 12 coupling element can solve the driver 18 by entering the notch 27 again from the biased standby position, whereupon the driver 18 (and thus the pull-out rail 12) by the force of the spring device 16 in the full Closed position is retractable.
Zum Spannen der Federvorrichtung 16 ist eine Koppelvorrichtung 30 in Form eines Hebelgetriebes vorgesehen, durch welches die zum Spannen der Federvorrichtung 16 erforderliche Kraft reduziert, ein plötzlicher unerwünschter Abriss der Federkraft (d.h. in jenem Moment, in dem der Mitnehmer 18 beim Öffnen in den abgebogenen Abschnitt 20 eintritt und dabei die Schublade 4 freigibt) sowie eine damit verbundene, übermäßige Beschleunigung der Schublade 4 in Öffnungsrichtung verhindert wird. Die Federvorrichtung 16 ist über einen vom Mitnehmer 18 gesonderten Federhalter 21 spannbar, wobei die Befestigungsstelle 22 der Federvorrichtung 16 mit dem Federhalter 21 verbunden ist. Der Federhalter 21 weist ein Lager 28 auf, an welchem ein zweiarmiger Hebel 23 um eine Drehachse 25 schwenkbar gelagert ist. Am zweiarmigen Hebel 23 ist an einem Hebelende zumindest ein Führungselement 24 angeordnet, welches entlang einer Steuerkurve 33 (Fig. 4) des Gehäuses 17 verschiebbar geführt ist. Das andere Hebelende des zweiarmigen Hebels 23 ist über eine Gelenkachse 36 mit einem, vorzugsweise bogenförmigen, Übertragungshebel 26 verbunden. Das andere Ende des Übertragungshebels 26 ist über ein Drehlager 29 mit dem Mitnehmer 18 bewegungsgekoppelt verbunden, wobei das Drehlager 29 des Übertragungshebels 26 in eine Öffnung 31 des Mitnehmers 18 eingreift. Das erste Hebelende und das zweite Hebelende des zweiarmigen Hebels 23 können unterschiedlich lang ausgebildet sein, wobei es aus kräftetechnischer Sicht von Vorteil ist, wenn das Führungselement 24 am längeren Hebelende des zweiarmigen Hebels 23 angeordnet ist. Fig. 4 zeigt die Einzugsvorrichtung 14 in einer von unten her gesehenen Explosionsdarstellung. Die Befestigungsstelle 22 der Federvorrichtung 16 ist in einer Ausnehmung 32 des Federhalters 21 formschlüssig verankerbar, das Lager 28 des Federhalters 21 dient zur schwenkbaren Lagerung des zweiarmigen Hebels 23 um die Drehachse 25. Das andere Hebelende des zweiarmigen Hebels 23 ist über den gekrümmten Übertragungshebel 26 mit dem Mitnehmer 18 gelenkig verbunden. Zur Führung des Mitnehmers 18 ist am Gehäuse 17 der Einzugsvorrichtung 14 ein linearer Verfahrweg 19 sowie ein daran anschließender gebogener Abschnitt 20 angeordnet oder ausgebildet. Der Mitnehmer 18 weist eine Führungsvorrichtung 34 in Form eines Vorsprungs auf, durch den der Mitnehmer 18 entlang des linearen Verfahrweges 19 und entlang des gebogenen Abschnitts 20 führbar ist. Ferner ist am Gehäuse 17 eine vom linearen Verfahrweg 19 gesonderte Steuerkurve 33 zur verschiebbaren Führung des Führungselementes 24 ausgebildet. Die Steuerkurve 33 weist einen linear verlaufenden Abschnitt und einen daran anschließenden gekrümmten Abschnitt auf, welcher mit dem letzten Spannweg der Federvorrichtung 6 korrespondiert. Durch das Zusammenwirken des zweiarmigen Hebels 23 mit dem gekrümmten Abschnitt der Steuerkurve 33 kann erreicht werden, dass im letzten Abschnitt des Spannweges der Federvorrichtung 16 bis hin zum Ende des Spannweges die Bewegung der Befestigungsstelle 22 der Federvorrichtung 6 am Federhalter 21 gegenüber der Position des verfahrenden Mitnehmers 18 zurückfällt, sodass im letzten Spannweg der Federvorrichtung 16 die Bewegung der Befestigungsstelle 22 langsamer als die Bewegung des Mitnehmers 18 ist. Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass die Länge des gekrümmten Abschnitts der Steuerkurve 33 - in Bezug auf die Gesamtlänge der Steuerkurve 33 - zumindest ein Drittel der Gesamtlänge der Steuerkurve 33 beträgt. Durch die Länge und Form der Steuerkurve 33 kann der Spannweg sowie der Kraftverlauf des Spannvorganges auf verschiedenste Art modifiziert werden, beispielsweise kann durch eine - in Bezug zum linearen Verfahrweg 19 - längere Steuerkurve 33 auch die zum Spannen erforderliche Kraft reduziert werden. For tensioning the spring device 16, a coupling device 30 is provided in the form of a lever mechanism by which reduces the force required to tension the spring device 16, a sudden unwanted break of the spring force (ie at that moment in which the driver 18 when opening in the bent portion 20 enters while the drawer 4 releases) and an associated, excessive acceleration of the drawer 4 in the opening direction is prevented. The spring device 16 can be tensioned via a spring holder 21 which is separate from the driver 18, wherein the fastening point 22 of the spring device 16 is connected to the spring holder 21. The spring holder 21 has a bearing 28 on which a two-armed lever 23 is pivotally mounted about an axis of rotation 25. At the two-armed lever 23, at least one guide element 24 is arranged on a lever end, which is displaceably guided along a control cam 33 (FIG. 4) of the housing 17. The other end of the lever of the two-armed lever 23 is connected via a hinge axis 36 with a, preferably arcuate, transmission lever 26. The other end of the transmission lever 26 is connected via a pivot bearing 29 with the driver 18 coupled to the movement, wherein the pivot bearing 29 of the transmission lever 26 engages in an opening 31 of the driver 18. The first end of the lever and the second end of the lever two-armed lever 23 may be formed differently long, it being advantageous from a technical standpoint when the guide member 24 is disposed at the longer end of the lever lever lever 23. Fig. 4 shows the collection device 14 in an exploded view from below. The attachment point 22 of the spring device 16 is positively anchored in a recess 32 of the spring holder 21, the bearing 28 of the spring holder 21 serves for pivotal mounting of the two-armed lever 23 about the rotation axis 25. The other end of the lever lever arm 23 is on the curved transmission lever 26 with the driver 18 hinged. To guide the driver 18, a linear travel path 19 and an adjoining bent portion 20 are arranged or formed on the housing 17 of the intake device 14. The driver 18 has a guide device 34 in the form of a projection, through which the driver 18 along the linear travel path 19 and along the curved portion 20 can be guided. Further, a separate from the linear travel path 19 control cam 33 is formed on the housing 17 for displaceable guidance of the guide element 24. The control cam 33 has a linearly extending section and an adjoining curved section, which corresponds to the last tensioning path of the spring device 6. By the interaction of the two-armed lever 23 with the curved portion of the control cam 33 can be achieved that in the last section of the clamping path of the spring device 16 up to the end of the clamping path, the movement of the attachment point 22 of the spring device 6 on the spring holder 21 with respect to the position of the traversing driver 18 falls back, so that in the last tension travel of the spring device 16, the movement of the attachment point 22 is slower than the movement of the driver 18. According to one embodiment, it may be provided that the length of the curved portion of the control cam 33 - with respect to the total length of the control cam 33 - at least one-third of the total length of the control cam 33. Due to the length and shape of the cam 33, the clamping path and the force curve of the clamping process can be modified in various ways, for example, by a - relative to the linear travel 19 - longer cam 33 and the force required for clamping can be reduced.
Fig. 5a-5d zeigen den Spannvorgang der Federvorrichtung 16 in zeitlichen Abfolgen. Ausgehend von der vollständigen Schließstellung gemäß Fig. 5a, in der die Federvorrichtung 16 weitgehend entspannt ist, wird durch eine manuelle Zugausübung auf das bewegbare Möbelteil 3 der Mitnehmer 18 entlang des linearen Verfahrweges 19 in Öffnungsrichtung 35 gezogen, wobei die Federvorrichtung 16 relativ zur ortsfesten Federbasis 15 (Fig. 2) gespannt wird. In einem ersten Spannabschnitt ΔΧ1 liegen etwa gleiche Bewegungsverhältnisse zwischen dem Mitnehmer 18 und der Befestigungsstelle 22 der Federvorrichtung 16 vor, d.h. die Befestigungsstelle 22 bewegt sich mit derselben Geschwindigkeit in Öffnungsrichtung 35 wie der Mitnehmer 18. Der am Federhalter 21 schwenkbar gelagerte zweiarmige Hebel 23 wird durch das Führungselement 24 entlang der Steuerkurve 33 geführt, wobei in einem zweiten Spannabschnitt ΔΧ2 eine in Bezug zum ersten Spannabschnitt ΔΧ1 verlangsamte Bewegung der Befestigungsstelle 22 herbeigeführt wird (Fig.5b). Durch das Zusammenwirken des Führungselementes 24 mit dem gekrümmten Abschnitt der Steuerkurve 33 wird der zweiarmige Hebel 23 im Uhrzeigersinn verschwenkt, sodass in einem dritten Spannabschnitt ΔΧ3 wiederum eine in Bezug zum zweiten Spannabschnitt ΔΧ2 verlangsamte Bewegung der Befestigungsstelle 22 relativ zu dem weiter sich in Öffnungsrichtung 35 bewegenden Mitnehmers 18 erfolgt. In Fig. 5d nimmt der Mitnehmer 18 eine gekippte, selbsthemmend arretierte Bereitschaftsstellung ein, in der die Kopplung zwischen dem bewegbaren Möbelteil 3 und dem Mitnehmer 18 aufgehoben ist, sodass das bewegbare Möbelteil 3 ungekoppelt weiter in Öffnungsrichtung 35 ausziehbar ist. 5a-5d show the clamping operation of the spring device 16 in time sequences. Starting from the complete closed position shown in FIG. 5a, in which the spring device 16 is largely relaxed, is by a manual Pulling exercise on the movable furniture part 3 of the driver 18 along the linear travel path 19 is pulled in the opening direction 35, wherein the spring device 16 is tensioned relative to the stationary spring base 15 (FIG. In a first tensioning section ΔΧ1 approximately equal movement conditions between the driver 18 and the attachment point 22 of the spring device 16 are present, ie the attachment point 22 moves at the same speed in the opening direction 35 as the driver 18. The two-armed lever 23 pivotally mounted on the spring holder 21 by the guide element 24 is guided along the control cam 33, wherein in a second tensioning section ΔΧ2 a movement of the fastening point 22 slowed down in relation to the first tensioning section ΔΧ1 is brought about (FIG. By the interaction of the guide member 24 with the curved portion of the cam 33 of the two-armed lever 23 is pivoted clockwise, so in a third clamping section .DELTA.Χ3 in turn with respect to the second clamping section .DELTA.Χ2 slowed movement of the attachment point 22 relative to the further moving in the opening direction 35 Driver 18 takes place. In Fig. 5d, the driver 18 assumes a tilted, self-locking locked ready position, in which the coupling between the movable furniture part 3 and the driver 18 is repealed, so that the movable furniture part 3 is further uncoupled in the opening direction 35 extendable.
Über die Spannabschnitte ΔΧ1 , ΔΧ2 und ΔΧ3 wird somit eine kontinuierliche, verlangsamte Bewegung der Befestigungsstelle 22 relativ zu dem sich in Öffnungsrichtung 35 bewegenden Mitnehmers 18 herbeigeführt, sodass die Federvorrichtung 16 nicht bis zur maximalen Federauslenkung gespannt wird. Das Spannen der Federvorrichtung 16 erfordert somit weniger Kraftaufwand, wobei der Übergangsbereich bzw. die Lastwechsel zwischen der gekoppelten und der ungekoppelten Stellung des Mitnehmers 18 deutlich harmonisiert werden, d.h. der unerwünschte Federabriss und eine damit verbundene unerwünschte Beschleunigung des bewegbaren Möbelteiles 3 beim Entkuppeln des Mitnehmers 18 von der Schublade 4 kann damit verhindert werden. Durch die durch die Koppelvorrichtung 30 herbeigeführte Untersetzung können auch Federvorrichtungen 16 mit hoher Federkraft mit einem reduzierten Kraftaufwand gespannt werden. Fig. 6a zeigt die Einzugsvorrichtung 14 in einer perspektivischen Ansicht, wobei die Federvorrichtung 16 relativ zur stationären Federbasis 15 gespannt werden kann. Fig. 6b zeigt den in Fig. 6a eingerahmten Bereich in einer vergrößerten Ansicht, wobei sich der Mitnehmer 18 in einer eingezogenen Endstellung befindet. Die Federvorrichtung 16 ist über die Befestigungsstelle 22 mit dem verfahrbaren Federhalter 21 verbunden, an welchem der zweiarmige Hebel 23 um eine Drehachse 25 schwenkbar gelagert ist. Das erste Hebelende des zweiarmigen Hebels 23 ist über eine Gelenkachse 36 mit einem ersten Ende des Übertragungshebels 26 verbunden, ein zweites Ende des Übertragungshebels 26 ist über ein Drehlager 29 mit dem Mitnehmer 18 gelenkig verbunden. Das zweite Hebelende des zweiarmigen Hebels 23 umfasst ein Führungselement 24, welches bei einer Bewegung des Mitnehmers 18 entlang der Steuerkurve 33 verschiebbar geführt ist. Zu erkennen ist, dass sich in der eingezogenen Stellung des Mitnehmers 18 die Befestigungsstelle 22, die Gelenkachse 36, die Drehachse 25 sowie das Drehlager 29 in einer Draufsicht im Wesentlichen auf einer gemeinsamen Linie befinden, welche der Wirkrichtung 37 der Federvorrichtung 16 entspricht. Durch diese fluchtende Anordnung der Bauteile können die Reibungskräfte der Einzugsvorrichtung 14 deutlich reduziert werden. Die kompakte Bauweise der Einzugsvorrichtung 14 ist auch daran erkennbar, dass im eingezogenen Zustand des Mitnehmers 18 der - entlang der Längserstreckung - bogenförmig ausgebildete Übertragungshebel 26 den zweiarmigen Hebel 23 umgreift. Überdies kann vorgesehen sein, dass der Federhalter 21 , der zweiarmige Hebel 23, der Übertragungshebel 26 sowie der Mitnehmer 18 - relativ zur Drehachse 25 - in Höhenrichtung voneinander beabstandet bzw. überlappend angeordnet sind. Durch diese verschachtelte Anordnung der Bauteile ist es möglich, einen Abschnitt des Mitnehmers 18 in Richtung zur Gelenkachse 36 hin zu verlängern, sodass insgesamt ein verlängerter Abschnitt des Mitnehmers 18 am linearen Verfahrweg 19 zur Anlage kommt. Dadurch ergibt sich auch eine verbesserte kippsichere Führung des Mitnehmers 18 bei einer Bewegung entlang des linearen Verfahrweges 19. Over the clamping sections ΔΧ1, ΔΧ2 and ΔΧ3 thus a continuous, slowed movement of the fastening point 22 is brought about relative to the moving in the opening direction 35 driver 18, so that the spring device 16 is not stretched to the maximum spring deflection. The tensioning of the spring device 16 thus requires less force, wherein the transition region or the load changes between the coupled and the uncoupled position of the driver 18 are clearly harmonized, ie the unwanted spring break and associated unwanted acceleration of the movable furniture part 3 when uncoupling the driver 18th from the drawer 4 can thus be prevented. By brought about by the coupling device 30 reduction spring devices 16 can be stretched with high spring force with a reduced effort. FIG. 6 a shows the collection device 14 in a perspective view, wherein the spring device 16 can be tensioned relative to the stationary spring base 15. Fig. 6b shows the framed in Fig. 6a area in an enlarged view, wherein the driver 18 is in a retracted end position. The spring device 16 is connected via the attachment point 22 with the movable spring holder 21, on which the two-armed lever 23 is pivotally mounted about an axis of rotation 25. The first lever end of the two-armed lever 23 is connected via a hinge axis 36 to a first end of the transmission lever 26, a second end of the transmission lever 26 is pivotally connected via a pivot bearing 29 with the driver 18. The second lever end of the two-armed lever 23 comprises a guide element 24, which is displaceably guided on a movement of the driver 18 along the control cam 33. It can be seen that in the retracted position of the driver 18, the attachment point 22, the hinge axis 36, the rotation axis 25 and the pivot bearing 29 are in a plan view substantially on a common line, which corresponds to the effective direction 37 of the spring device 16. By this aligned arrangement of the components, the frictional forces of the intake device 14 can be significantly reduced. The compact construction of the intake device 14 can also be seen from the fact that in the retracted state of the driver 18 of the - along the longitudinal extent - arcuate transmission lever 26 surrounds the two-armed lever 23. Moreover, it can be provided that the spring holder 21, the two-armed lever 23, the transmission lever 26 and the driver 18 - are arranged spaced from each other in the vertical direction or relative to the axis of rotation 25. By this nested arrangement of the components, it is possible to extend a portion of the driver 18 in the direction of the hinge axis 36, so that a total of an extended portion of the driver 18 comes to rest on the linear path 19. This also results in an improved non-tilting guidance of the driver 18 during a movement along the linear travel path 19.
Als Federvorrichtungen 16 kann zumindest eine Schraubenfeder Verwendung finden, welche vorzugsweise als Zugfeder ausgebildet ist. Zur Aufbringung einer höheren Federkraft können auch Federpakete mit zwei oder mehreren parallel geschalteten Schraubenfedern Verwendung finden, welche beim Spannvorgang alle gleich weit gezogen werden. As spring devices 16, at least one coil spring can be used, which is preferably designed as a tension spring. To apply a higher spring force and spring assemblies with two or more parallel connected Coil springs find use, which are all the same pulled during the clamping process.
