Description

Die Erfindung bezieht sich auf eine Einzugvorrichtung fÌr Möbel mit einer Einzuganordnung, die eine Einzugfeder aufweist, und mit einer DÀmpfvorrichtung, wobei die Einzugfeder und die DÀmpfvorrichtung an ein Koppelelement mittelbar oder unmittelbar angeschlossen sind, das zwischen einer Parkposition und einer Einzugposition verstellbar ist, wobei die Einzugvorrichtung das Koppelelement von der Parkposition in die Einzugposition zumindest bereichsweise bewegt und die DÀmpfvorrichtung die Verstellbewegung des Koppelelements von der Parkposition in die Einzugposition zumindest bereichsweise dÀmpft.The invention relates to a retraction device for furniture with a retractable assembly, which has a retraction spring, and with a damping device, wherein the retraction spring and the damping device are connected directly or indirectly to a coupling element which is adjustable between a parking position and a retraction position, wherein the Retracting device, the coupling element from the parking position in the retraction position moves at least partially and the damping device attenuates the adjustment of the coupling element of the parking position in the retraction position at least partially.

Eine Einzugvorrichtung dieser Art ist in der DE 10 2010 000 341 A1 angegeben. Diese ist insbesondere fÃŒr den Einsatz bei Möbeln mit SchiebetÃŒren geeignet. Hierbei ist ein Koppelelement zwischen einer Einzugsposition und einer Parkposition in einem GehÀuse linear verstellbar. In der Parkposition bei geöffneter SchiebetÃŒr ist das Koppelelement gekippt und hÀlt eine Einzugfeder komplett unter Vorspannung. Beim Schließen der SchiebetÃŒr, im letzten Teil der Schließbewegung, fÀngt das Kippelement einen an der SchiebetÃŒr montierten Mitnehmer auf. Durch den Aufprall des Mitnehmers am Koppelelement wird dieses aus der gekippten Stellung heraus bewegt und durch die gespannte Einzugfeder in Richtung Einzugposition gezogen, wobei es den Mitnehmer mitnimmt. Die Einzugsbewegung wird durch eine DÀmpfvorrichtung gedÀmpft, sodass eine harmonische, kontinuierliche Schließbewegung erzeugt wird.A feeder of this type is in the DE 10 2010 000 341 A1 specified. This is particularly suitable for use with furniture with sliding doors. Here, a coupling element between a retraction position and a parking position in a housing is linearly adjustable. In the parking position with the sliding door open, the coupling element is tilted and holds a pull-in spring completely under tension. When closing the sliding door, in the last part of the closing movement, the tilting element intercepts a driver mounted on the sliding door. Due to the impact of the driver on the coupling element of this is moved out of the tilted position and pulled by the tensioned feed spring in the direction of retraction position, taking with it the driver. The retraction movement is damped by a damping device, so that a harmonious, continuous closing movement is generated.

Ähnlich wirkende Einzugvorrichtungen sind in der DE 20 2004 006 410 U1 und der EP 1 658 785 B1 angegeben.Similar-looking intake devices are in the DE 20 2004 006 410 U1 and the EP 1 658 785 B1 specified.

Insbesondere bei Einzugsvorrichtungen mit langen Federwegen kann es vorkommen, dass gegen Ende der Einzugsbewegung die Federkraft nicht mehr ausreichend groß ist, um die MöbeltÃŒr vollstÀndig und fest zu schließen. Wird die Einzugfeder steifer ausgelegt, kann jedoch zu Beginn der Einzugsbewegung die einziehende Kraft verhÀltnismÀßig hoch werden und in einer zu geringen DÀmpfung resultieren. Zudem kann die wÀhrend des TÃŒröffnens die durch einen Bediener aufzubringende Spannkraft der Einzugsfeder relativ hoch werden und so den Bedienkomfort beeinflussen.Especially with collection devices with long spring travel, it may happen that at the end of the retraction movement, the spring force is no longer is sufficiently large to close the furniture door completely and firmly. If the pull-in spring is made stiffer, however, at the beginning of the pull-in movement, the retracting force can become relatively high and result in too little damping. In addition, during the door opening, the clamping force of the pull-in spring to be applied by an operator can become relatively high and thus influence the operating convenience.

WO 2010/143352 A1 offenbart eine Einzugvorrichtung fÃŒr Möbel. Dabei kann mit der Einzugvorrichtung eine Schublade in eine Einzugposition verstellt werden. Die Einzugvorrichtung besitzt ein Koppelelement. Dieses Koppelelement kann mit einem schubladenseitigen Mitnehmer gekoppelt werden. Das Koppelelement ist gleichzeitig an einen DÀmpfer und eine Einzugfeder angeschlossen. Es ist ein weiteres Koppelelement vorgesehen, welches ebenfalls an einen DÀmpfer und eine Einzugfeder angeschlossen ist. WÀhrend das erste Koppelelement ÃŒber den gesamten Einzugweg verstellt werden kann, lÀsst sich das zweite Koppelelement nur ÃŒber einen Teil des gesamten Einzugwegs verstellen. Im Verlauf seiner Einzugbewegung nimmt das erste Koppelelement ab einer bestimmten Teilstrecke das zweite KoppelstÃŒck mit. Über die gekoppelten Koppelelemente und können beide Federn auf den Mitnehmer einwirken. WO 2010/143352 A1 discloses a collection device for furniture. It can be adjusted with the feeder a drawer in a retraction position. The feeder has a coupling element. This coupling element can be coupled with a drawer side driver. The coupling element is simultaneously connected to a damper and a pull-in spring. It is provided a further coupling element, which is also connected to a damper and a pull-in spring. While the first coupling element can be adjusted over the entire Einzugsweg, the second coupling element can be adjusted only over part of the entire feed path. In the course of its retraction movement, the first coupling element takes along with the second coupling piece from a certain distance. About the coupled coupling elements and both springs can act on the driver.

Der Erfindung liegt die Aufgabe zugrunde, eine optimierte Einzugvorrichtung bereitzustellen, die mit geringem Bauraum eine flexiblere Anpassung an unterschiedliche Möbelgestaltungen ermöglicht.The invention has for its object to provide an optimized feeder, which allows a small space with a more flexible adaptation to different furniture designs.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die Einzuganordnung zumindest ein zusÀtzliches Einzugelement (SekundÀrfeder) aufweist, das ab einer zwischen der Parkposition und der Einzugposition befindlichen Zwischenposition eine zusÀtzliche Einzugkraft auf das Koppelelement aufbringt. Das Koppelelement kann dabei beispielsweise als Kippsegment ausgefÌhrt sein, welches schwenkbar gelagert ist und in der Parkposition in einen Parkabschnitt abgekippt ist.This object is achieved with the features of claim 1. In this case, it is provided that the intake arrangement has at least one additional intake element (secondary spring) which, starting from an intermediate position located between the parking position and the intake position, applies an additional pull-in force to the coupling element. The coupling element may for example be designed as a tilting segment, which is pivotally mounted and is tilted in the parking position in a parking section.

ErfindungsgemÀß kann auf einfache Weise ab einer fÃŒr den jeweiligen Bedarfsfall definierten Position durch die zusÀtzliche Einzugkraft die Einzugbewegung verstÀrkt werden. Dies ist insbesondere im Bereich nahe der Einzugposition sinnvoll, da auf diese Weise die nachlassende Einzugkraft der Einzugfeder zumindest teilweise kompensiert und so ein sicheres Schließen von insbesondere einer Schiebe-, aber auch einer anderen MöbeltÃŒr gewÀhrleistet werden kann.According to the invention, the retraction movement can be increased in a simple manner from a position defined for the respective requirement case by the additional pull-in force. This is particularly useful in the area close to the retraction position, since in this way the declining retraction force of the retraction spring at least partially compensated and so a safe closing of a particular sliding, but also another furniture door can be guaranteed.

ErfindungsgemÀß ist ein Ende des zusÀtzlichen Einzugelements an ein Arretiersegment gekoppelt, welches das zusÀtzliche Einzugelement unter Spannung hÀlt, und das andere Ende des zusÀtzlichen Einzugelements ist an das GehÀuse angekoppelt. Das Arretiersegment ermöglicht eine einfache Festlegung des zusÀtzlichen Einzugelements in einer Vorspannposition, sodass die Feder in einer aufgeladenen Position gehalten werden und bei Bedarf eine zusÀtzliche Einzugkraft aufbringen kann. Weiterhin kann es vorgesehen sein, dass das zusÀtzliche Einzugelement auch in der Einzugposition, in welcher eine SchiebetÃŒr vollstÀndig geschlossen ist, unter Spannung. So kann es auch in dieser am wenigsten gespannten Position eine wirksame Einzugskraft aufbringen und ist zudem sicher in der Einzugvorrichtung gelagert. Die zusÀtzliche Kopplung am vorhandenen GehÀuse minimiert den Teileaufwand.According to the invention, one end of the additional pull-in element is coupled to a locking segment which holds the additional pull-in element under tension, and the other end of the additional pull-in element is coupled to the housing. The locking segment allows for easy fixing of the additional pull-in element in a biasing position, so that the spring can be held in a charged position and can apply an additional pull-in force if necessary. Furthermore, it can be provided that the additional intake element in the retraction position, in which a sliding door is fully closed, under tension. So it can muster an effective retracting force in this least tensioned position and is also safely stored in the feeder. The additional coupling on the existing housing minimizes the parts cost.

Wenn erfindungsgemÀß in einer Öffnungsbewegung der Mitnehmer bewegt wird, werden gleichzeitig die Einzugfeder und das zusÀtzliche Einzugelement durch die Kraft, die diese Bewegung ausfÃŒhrt, gespannt. Somit werden sie energetisch aufgeladen, d.h. sie speichern die ihnen zugefÃŒhrte Energie. Die KraftÃŒbertragung erfolgt ÃŒber das Koppelelement, welches die Kraft ÃŒber den Schlitten sowohl auf die Einzugfeder als auch auf das Arretiersegment und so auf das zusÀtzliche Spannelement ÃŒbertrÀgt. Hierdurch wird eine platzsparende Bauweise ermöglicht, die hinsichtlich der Positioniermöglichkeiten des Koppelementes optimiert ausgebildet ist.If, according to the invention, the driver is moved in an opening movement, the pull-in spring and the additional pull-in element are simultaneously tensioned by the force which carries out this movement. Thus, they are charged energetically, i. they store the energy supplied to them. The power transmission takes place via the coupling element which transmits the force via the carriage both to the pull-in spring and to the locking segment and thus to the additional clamping element. As a result, a space-saving design is possible, which is designed optimized in terms of positioning possibilities of the coupling element.

Vorteilhaft ist es vorgesehen, dass das zusÀtzliche Einzugelement eine parallel zur Einzugfeder wirkende SekundÀrfeder ist. Eine SekundÀrfeder kann platzsparend zusÀtzlich zu der Einzugfeder in die Einzugvorrichtung eingebracht werden und erlaubt eine einfache Auslegung entsprechend der benötigten Geometrie- und KraftverhÀltnisse.It is advantageously provided that the additional feed element is a parallel to the feed spring acting secondary spring. A secondary spring can be introduced to save space in addition to the feed spring in the feeder and allows a simple design according to the required geometry and force ratios.

Von Vorteil ist, dass bei zwischen der Einzugposition und der Zwischenposition befindlichem Koppelelement das zusÀtzliche Einzugelement ÃŒber mindestens das Arretiersegment mit dem Koppelelement gekoppelt ist, wobei sich das Arretiersegment mit dem Koppelelement mitbewegt. Auf diese Weise kann das zusÀtzliche Einzugelement ÃŒber die Bewegung eines Mitnehmers, welches das Koppelelement beim Öffnen einer SchiebetÃŒr mitnimmt, bei der TÃŒröffnung gespannt werden, was eine einfache Bedienung ermöglicht.It is advantageous that when located between the feed position and the intermediate position coupling element, the additional feed element is coupled via at least the locking segment with the coupling element, wherein the locking segment moves with the coupling element. In this way, the additional intake element via the movement of a driver, which entrains the coupling element when opening a sliding door, be stretched at the door opening, which allows easy operation.

Bei einer Entkopplung des zusÀtzlichen Einzugelements von dem Koppelelement bei zwischen der Zwischenposition und der Parkposition befindlichem Koppelelement wird die in einer solchen Position aufzubringende Kraft beim Öffnen einer SchiebetÃŒr reduziert. In diesem Bereich ist die Einzugkraft, die dem Öffnen der TÃŒr entgegenwirkt, verhÀltnismÀßig hoch. Hier bringt bereits die Einzugfeder aufgrund des langen Spannwegs eine hohe Spannkraft auf. Daher erhöht es den Bedienkomfort, wenn hier nicht zusÀtzlich eine weitere Einzugkraft dem Öffnen entgegenwirkt.In a decoupling of the additional feeder element of the coupling element located between the intermediate position and the parking position coupling element, the force to be applied in such a position when opening a sliding door is reduced. In this area, the pull-in force, which counteracts the opening of the door, is relatively high. Here already brings the feed spring due to the long clamping path on a high clamping force. Therefore, it increases the ease of use, if not another additional pulling force counteracts the opening here.

Zweckdienlich ist bei zwischen der Zwischenposition und der Parkposition befindlichem Koppelelement das zusÀtzliche Einzugelement ÃŒber das Arretiersegment an das GehÀuse gekoppelt und unter Zugvorspannung gehalten. Das zusÀtzliche Einzugelement ist auf diese Art energetisch aufgeladen, ohne dass es in die weitere Bewegung der Schiebevorrichtung eingreift. So ist es bereit, bei einer Schließbewegung der SchiebetÃŒr ab der Zwischenposition wirksam zu werden und eine zusÀtzliche Einzugskraft aufzubringen. Die Kopplung an das GehÀuse minimiert dabei den Teileaufwand bei Montage.Conveniently, when located between the intermediate position and the parking position coupling element, the additional intake element coupled via the locking segment to the housing and held under tensile prestress. The additional intake element is energetically charged in this way, without it interfering with the further movement of the pusher. So it is ready to be effective at a closing movement of the sliding door from the intermediate position and apply an additional retracting force. The coupling to the housing minimizes the parts costs during assembly.

Wenn vorgesehen ist, dass das Arretiersegment ein Halteteil aufweist, an das das zusÀtzliche Einzugelement unmittelbar gekoppelt ist, ergibt sich ein einfacher Aufbau.If it is provided that the locking segment has a holding part, to which the additional intake element is directly coupled, results in a simple structure.

Vorteilhafterweise weist das Arretiersegment mindestens ein Steuerelement (Vorsprung mit einer SteuerflÀche; SchrÀge) auf, an dem das Arretiersegment mittels eines Gegenelements (Steuerelement; Leitelement) aus einer der Zwischenposition zugeordneten Haltestellung heraus- und/oder in diese hineinbewegbar ist. Dies ermöglicht es, das Ab- und Ankoppeln des Arretiersegmentes an das Koppelelement bzw. das An- und Abkoppeln an das GehÀuse beim Öffnen und Schließen der SchiebetÃŒr harmonisch in die Öffnungs- und Schließbewegung zu integrieren.Advantageously, the locking segment has at least one control element (projection with a control surface, bevel) on which the locking segment can be moved out of and / or into a holding position assigned to a holding position by means of a counter element (control element; This makes it possible to harmoniously integrate the disconnection and coupling of the Arretiersegmentes to the coupling element and the coupling and uncoupling to the housing when opening and closing the sliding door in the opening and closing movement.

Eine vorteilhafte Ausgestaltungsvariante sieht vor, dass das Arretiersegment eine GegenflÀche aufweist zur Bildung einer Anschlagverbindung, Ìber die eine KraftÌbertragung zwischen dem Koppelelement und dem zusÀtzlichen Einzugselement beim Verstellen von der Einzugposition in die Zwischenposition und/oder umgekehrt vorgenommen ist. So werden die aufgrund des zusÀtzlichen Einzugselementes wirksamen KrÀfte auf einfache und effektive Weise zwischen dem zusÀtzlichen Einzugselement und dem mittelbar betroffenen, an der SchiebetÌr angebrachten Mitnehmer Ìbertragen.An advantageous embodiment variant provides that the locking segment has a counter surface to form a stop connection, via which a power transmission between the coupling element and the additional catch element when adjusting from the feed position to the intermediate position and / or vice versa is made. Thus, the effective due to the additional catch element forces are transmitted in a simple and effective manner between the additional catchment element and the indirectly affected, attached to the sliding door driver.

FÃŒr eine einfache Arretierung ist es dienlich, wenn das Arretiersegment mittels einer Anschlagverbindung in der Haltestellung arretiert ist.For a simple locking, it is useful if the locking segment is locked by means of a stop connection in the holding position.

ZweckmÀßig ist vorgesehen, dass das GehÀuse Elemente zur linearen FÃŒhrung, zum Festlegen und/oder zum Loslösen der Festlegung des Arretiersegmentes aufweist. Somit ÃŒbernimmt das GehÀuse mehrere Funktionen, was den Teileaufwand minimiert.Suitably, it is provided that the housing has elements for linear guidance, for fixing and / or for releasing the fixing of the locking segment. Thus, the housing takes over several functions, which minimizes the parts cost.

Dass die Einzugfeder an das Koppelelement mittelbar oder unmittelbar derart angekoppelt ist, dass dieses in der Parkposition unter Federvorspannung steht, ermöglicht die Aufbringung einer Einzugkraft auf den Mitnehmer auf einer kompletten Einzugstrecke zwischen Parkpostion und Einzugposition, was wiederum einem sicheren Schließen der SchiebetÃŒr dienlich ist.That the retraction spring is coupled directly or indirectly to the coupling element in such a way that it is spring-biased in the parking position, allows the application of a retraction force on the catch on a complete retraction distance between the parking position and the retraction position, which in turn is useful for securely closing the sliding door.

Eine bevorzugte Ausgestaltungvariante sieht vor, dass das Koppelelement an einem Schlitten angekoppelt ist, und dass der Schlitten an das der Einzugposition abgewandte Ende der DÀmpfvorrichtung oder das der Einzugsposition abgewandte Stellteil (Zylinder, Kolbenstange) der DÀmpfvorrichtung gekoppelt ist. Auf diese Weise lÀsst sich das Koppelelement unter geringem Aufwand bis dicht an den Seitenbereich des GehÀuses ziehen.A preferred embodiment variant provides that the coupling element is coupled to a carriage, and that the carriage to the retraction position opposite end of the damping device or the retraction position facing away from the adjusting part (cylinder, piston rod) of the damping device is coupled. In this way, the coupling element can be pulled with little effort to close to the side region of the housing.

HierfÌr ist es weiterhin vorteilhaft, dass das Koppelelement in dem GehÀuse verstellbar gelagert ist und dass das Koppelelement in der Einzugposition bis in den Bereich einer GehÀuseseite verfahren ist und in der Parkposition zwischen dieser und einer gegenÌberliegenden GehÀuseseite steht. Dies verkleinert den Bauraum der Einzugvorrichtung.For this purpose, it is further advantageous that the coupling element is adjustably mounted in the housing and that the coupling element is moved in the retraction position into the region of a housing side and is in the parking position between this and an opposite side of the housing. This reduces the space of the feeder.

Dadurch, dass die DÀmpfvorrichtung einen LineardÀmpfer aufweist und dass die Wirkrichtung der Einzugfeder und der DÀmpfvorrichtung zueinander parallel ist, kann der Bauraum der Einzugsvorrichtung verkleinert werden.The fact that the damping device has a linear damper and that the direction of action of the retraction spring and the damping device is parallel to each other, the space of the retraction device can be reduced.

Fig. 1 zeigt eine Einzugvorrichtung 1, welche mit einem Mitnehmer 90 in Wirkverbindung steht, in einer Einzugposition. Der Mitnehmer 90 ist mit einer, hier nicht dargestellten, SchiebetÃŒr fest verbunden, beispielsweise ÃŒber eine Schraubverbindung. Die Einzugvorrichtung 1 weist ein GehÀuse 20 mit jeweils stirnseitig angeordneten Schraubenaufnahmen 21 zur formschlÃŒssigen Aufnahme von Befestigungsschrauben auf, mit welchen das GehÀuse 20 an einem MöbelstÃŒck fest angebracht werden kann. Um Einsicht in das Innenleben der Einzugvorrichtung 1 zu gewÀhren, ist das GehÀuse 20 offen, d.h. ohne einen zum Verschließen vorgesehenen Deckel dargestellt. Dabei sind die SeitenflÀche 202 des GehÀuses 20 und der Deckel parallel zu einer MittellÀngsebene der Einzugvorrichtung 1 angeordnet. Fig. 1 shows a feeder 1, which is in operative connection with a driver 90, in a retracted position. The driver 90 is fixedly connected to a sliding door, not shown here, for example via a screw connection. The feeder device 1 has a housing 20, each with an end face arranged screw receptacles 21 for the positive reception of mounting screws, with which the housing 20 can be fixedly attached to a piece of furniture. In order to provide insight into the interior of the feeder 1, the housing 20 is open, that is shown without a cover provided for closing. In this case, the side surface 202 of the housing 20 and the cover are arranged parallel to a central longitudinal plane of the intake device 1.

In dem GehÀuse 20 ist in LÀngsrichtung eine DÀmpfvorrichtung 30 angeordnet. Unterhalb der DÀmpfvorrichtung 30 befindet sich parallel dazu eine Einzugfeder 40. Überhalb der DÀmpfvorrichtung 30 ist ein Schlitten 50 angeordnet, an welchem nahe der rechten Stirnseite des GehÀuses 20 ein Koppelelment 60 schwenkbar gelagert ist. An dem von dem Koppelelement 60 abgewandten Ende des Schlittens 50 liegt ein Arretiersegment 80 in Position, um mit dem Schlitten 50 in Anschlagverbindung zu treten. An dem Arretiersegment 80 ist an einem Halteteil 81 ein zusÀtzliches Einzugelement 70 mit einem Ende angebracht. Das gegenÃŒberliegende Ende des zusÀtzlichen Einzugelementes 70, das dem Koppelelement 60 zugewandt ist, ist mit dem GehÀuse 20 verbunden.In the housing 20, a damping device 30 is arranged in the longitudinal direction. Below the damping device 30 is parallel to a feed spring 40. Above the damping device 30, a carriage 50 is arranged, on which near the right end side of the housing 20, a coupling element 60 is pivotally mounted. At the end remote from the coupling element 60 end of the carriage 50 is a locking segment 80 in position to contact the carriage 50 in abutment connection. At the locking segment 80, an additional feed element 70 is attached to one end of a holding part 81. The opposite end of the additional pull-in element 70, which faces the coupling element 60, is connected to the housing 20.

Fig. 2 zeigt die einzelnen Komponenten der Einzugvorrichtung 1 in perspektivischer Darstellung, die nÀhere Einzelheiten erkennen lÀsst. Wie Fig. 2 erkennen lÀsst, weist das GehÀuse 20 eine in LÀngsrichtung verlaufende DÀmpfvorrichtungsaufnahme 29 auf. An deren der GehÀusestirnseite zugewandtem Ende, angrenzend an die Schraubenaufnahme 21, befindet sich ein DÀmpfvorrichtungshalter 23. Unterhalb der DÀmpfvorrichtungsaufnahme 29 ist eine Einzugfederaufnahme 201 vorgesehen, welche an ihrem der GehÀusestirnseite zugewandtem Ende einen Einzugfederhalter 22 aufweist. Oberhalb der DÀmpfvorrichtungsaufnahme 29 befindet sich eine Schlittenaufnahme 24, in welcher der Schlitten 50 in LÀngsrichtung beweglich angeordnet werden kann. Im Bereich der Schlittenaufnahme 24 sind ein Halter 25 fÌr das zusÀtzliche Einzugelement 70 sowie zwei AnschlÀge 26, ein FÌhrungssteg 27 und ein Leitelement 28 angeordnet. Fig. 2 shows the individual components of the intake device 1 in a perspective view, which reveals details. As Fig. 2 can recognize, the housing 20 has a longitudinally extending DÀmpfvorrichtungsaufnahme 29. At the housing end side facing the end, adjacent to the A damping spring holder 23 is located underneath the damping device receptacle 29 and has a catch spring holder 22 at its end facing the housing end side. Above the DÀmpfvorrichtungsaufnahme 29 is a slide receptacle 24, in which the carriage 50 can be arranged to be movable in the longitudinal direction. In the region of the carriage seat 24, a holder 25 for the additional feed element 70 and two stops 26, a guide web 27 and a guide element 28 are arranged.

Die DÀmpfvorrichtung 30, die in Fig. 2 in vollstÀndig eingezogenem Zustand gezeigt ist, weist zwei DÀmpfer 31 mit Zylindern auf, in welchen jeweils Kolbenstangen 34 dÀmpfend auf einer Achse, jedoch in entgegengesetzte Richtungen, beweglich sind. An den Enden der Kolbenstangen 34 sind jeweils BefestigungsstÌcke 33 angeformt. Die DÀmpfer sind Ìber einen Verbinder 32 linear gekoppelt.The damping device 30, which in Fig. 2 is shown in the fully retracted state, has two dampers 31 with cylinders, in each of which piston rods 34 are attenuating on an axis, but in opposite directions, movable. At the ends of the piston rods 34 each attachment pieces 33 are integrally formed. The dampers are linearly coupled via a connector 32.

Der Schlitten 50 weist an seinem dem Koppelelement 60 zugewandten Ende eine Koppelelementaufnahme 59 auf. An dieser befindet sich ein Lager 51 zur beweglichen Aufnahme des Koppelelements 60. In LÀngsrichtung erstreckt sich ein Basisteil 53, welches rahmenartig ausgebildet und ohne innere Wand ausgefÌhrt ist. Denkbar ist auch eine AusfÌhrung, in welcher innerhalb des Rahmens eine Wand eingebracht ist. An dem dem Koppelelement 60 abgewandten Ende des Schlittens 50 befindet sich in dem oberen, in Richtung der GehÀusewand weisenden Teil des Rahmes ein Absatz 54. Dieser bildet einen auf die Rahmeninnenseite weisenden Spannungsanschlag 55. An demselben Ende des Schlittens 50 ist an der Stirnseite ein Steuerelement 56 angeformt, welches mit einem gerundeten Ende in den Rahmen hineinragt. Dabei ist das gerundete Ende axial beanstandet von dem Absatz 55. An dem betreffenden Ende des Schlittens 50 ist weiterhin, auf der in Richtung des DÀmpfelements 30 weisenden Unterseite des Basisteils 53, ein DÀmpferhalter 58 sowie ein Federhalter 57 angeformt.The carriage 50 has a coupling element receptacle 59 on its end facing the coupling element 60. At this there is a bearing 51 for movably receiving the coupling element 60. In the longitudinal direction, a base member 53 which is formed like a frame and without an inner wall extends. Also conceivable is an embodiment in which a wall is inserted within the frame. At the end of the carriage 50 facing away from the coupling element 60, there is a shoulder 54 in the upper part of the frame pointing in the direction of the housing wall. This forms a tension stop 55 pointing to the inside of the frame. At the same end of the slide 50, a control element is provided on the front side 56 molded, which protrudes with a rounded end in the frame. In this case, the rounded end is axially spaced from the paragraph 55. At the respective end of the carriage 50 is further, on the pointing in the direction of the damping element 30 bottom of the base member 53, a damper holder 58 and a spring holder 57 formed.

Das Koppelelement 60 ist mit einer StoßflÀche 61 und einem Sperrelement 63 ausgestattet, welche zusammen eine Mitnehmeraufnahme 62 bilden. Zudem weist es einen Ausleger 65 auf, an dessen Ende ein FÃŒhrungsansatz 64 beidseitig herausragt. Von dem Ende des Auslegers 65 erstreckt sich zudem ein Federarm 68 schrÀg nach oben und in Richtung der Mitnehmeneraufnahme 62. Dabei wird die Bewegungsmöglichkeit des Federarms nach oben durch einen Arretieransatz 66 begrenzt. An dem dem Ausleger 65 abgewandten Ende des Koppelelements 60 befindet sich ein Lageransatz 67 zur beweglichen Lagerung des Koppelelements 60 im Lager 51.The coupling element 60 is equipped with an abutment surface 61 and a blocking element 63, which together form a driver receptacle 62. In addition, it has a boom 65, at its end a guide projection 64 on both sides protrudes. From the end of the boom 65 also extends a spring arm 68 obliquely upwards and in the direction of the takeaway receiver 62. The possibility of movement of the spring arm is bounded above by a Arretieransatz 66. At the end of the coupling element 60 facing away from the arm 65 there is a bearing projection 67 for movably supporting the coupling element 60 in the bearing 51.

Das Arretiersegment 80 ist durch einen sich von dem Halteteil 81 erstreckenden Arm 82 lÀnglich ausgebildet. An dem Arm 82 ist in Richtung des von dem Halteteil 81 abgewandten Endes ein Vorsprung 83 angeformt, der eine GegenflÀche 831 und eine SteuerflÀche 832 aufweist. An dem von dem Halteteil 81 abgewandten Ende weist das Arretiersegment 80 eine SchrÀge 84 und eine nach unten ausgerichtete Nase 85 auf.The locking segment 80 is formed by an extending from the holding part 81 arm 82 elongated. On the arm 82, a projection 83 is formed in the direction of the end facing away from the holding part 81, which has a counter surface 831 and a control surface 832. At the end facing away from the holding part 81, the locking segment 80 has a bevel 84 and a downwardly directed nose 85.

Die Funktionen der Komponenten der Einzugvorrichtung 1 lassen die Figuren 1, 3 und 4 und ihre jeweiligen Detaildarstellungen Fig. 1a, 3a und 4a erkennen. Die Figuren zeigen die Einzugvorrichtung 1 im Übergang von einem geschlossenen in einen geöffneten Zustand einer MöbeltÃŒr, die insbesondere eine SchiebetÃŒr sein kann. In der Schließbewegung ist die Reihenfolge umgekehrt. In dem vollstÀndig geschlossenem Zustand steht das Koppelelement 60 in der Einzugposition (Fig. 1 und 1a). Nachdem die TÃŒr etwas geöffnet wurde, passiert das Koppelelement 60 eine Zwischenposition (Fig. 3 und 3a), nach welcher sich bei Teil- oder vollstÀndig geöffnetem Zustand der TÃŒr eine Parkposition (Fig. 4 und 4a) ergibt.The functions of the components of the feeder 1 let the FIGS. 1 . 3 and 4 and their respective detailed representations Fig. 1a . 3a and 4a detect. The figures show the intake device 1 in the transition from a closed to an open state of a furniture door, which may be in particular a sliding door. In the closing movement, the order is reversed. In the fully closed state, the coupling element 60 is in the retracted position ( Fig. 1 and 1a ). After the door has been slightly opened, the coupling element 60 passes an intermediate position ( Fig. 3 and 3a ), after which, when the door is partially or fully opened, a parking position ( 4 and 4a ).

In der in Fig. 1 und 1a gezeigten Einzugposition befindet sich das Koppelelement 60 vollstÀndig auf der rechten, in Schließrichtung weisenden Seite des GehÀuses 20. Es steht mit einem Mitnehmer 90 einer SchiebetÃŒr derart in Wirkverbindung, dass eine KraftÃŒbertragung zwischen dem Mitnehmer 90 und der Einzugvorrichtung 1 stattfinden kann, sobald eine Kraft wirksam wird. Sowohl die Einzugfeder 40 als auch das zusÀtzliche Einzugelement 70 sind minimal gespannt, d.h. sie liegen in ihrer kÃŒrzesten Ausdehnung vor, wobei sie dennoch eine Spannung aufweisen. Bei der zusÀtzlichen Einzugvorrichtung 70 wird diese Spannung dadurch erhalten, dass das Arretiersegment 80 mit seinem Halteteil 81, an welchem ein Ende der zusÀtzlichen Einzugvorrichtung 70 angekoppelt ist, an den AnschlÀgen 26 aufsitzt. Die Spannung könnte beispielsweise auch durch die Anschlagverbindung zwischen dem Spannungsanschlag 55 und der GegenflÀche 831 aufrecht erhalten werden. Wie Fig. 1a zeigt, ist der Arm 82 des Arretiersegments 80 derart gekippt, dass das Arretiersegment 80 linear beweglich auf dem FÃŒhrungssteg 27 des GehÀuses 20 aufliegt. Zudem ist das Arretiersegment 80 in einer orthogonal zur MittellÀngsebenen verlaufenden Querachse jeweils seitlich gefÃŒhrt, von der SeitenflÀche des GehÀuses 20 und dessen Deckel. Daneben ist es denkbar, dass sich das Arretiersegment 80 auf einer Seite auf einer Wand des Schlittens 50 oder eines anderen Elements abstÃŒtzt.In the in Fig. 1 and 1a It is in operative connection with a driver 90 of a sliding door in such a way that a power transmission between the driver 90 and the intake device 1 can take place as soon as a force is effective becomes. Both the pull-in spring 40 and the additional pull-in element 70 are minimally tensioned, ie they are in their shortest extent, yet they have a voltage. In the additional feeder 70, this voltage is obtained by the locking segment 80 with its holding part 81, to which one end of the additional Feeding device 70 is coupled, is seated on the stops 26. The tension could, for example, also be maintained by the abutment connection between the tension stop 55 and the mating surface 831. As Fig. 1a shows, the arm 82 of the locking segment 80 is tilted such that the locking segment 80 rests linearly movable on the guide web 27 of the housing 20. In addition, the locking segment 80 is guided laterally in each case in a transverse axis extending orthogonally to the central longitudinal planes, from the side surface of the housing 20 and its lid. In addition, it is conceivable that the locking segment 80 is supported on one side on a wall of the carriage 50 or another element.

Wird nun in einer Öffnungsbewegung der Mitnehmer 90 nach links bewegt, werden gleichzeitig die Einzugfeder 40 und das zusÀtzliche Einzugelement 70 durch die Kraft, die diese Bewegung ausfÃŒhrt, gespannt. Somit werden sie energetisch aufgeladen, d.h. sie speichern die ihnen zugefÃŒhrte Energie. ErfindungsgemÀß erfolgt die KraftÃŒbertragung ÃŒber das Koppelelement 60, welches die Kraft ÃŒber den Schlitten 50 sowohl auf die Einzugfeder 40 als auch auf das Arretiersegment 80 und so auf das zusÀtzliche Spannelement 70 ÃŒbertrÀgt. Die Aufladung erfolgt bis zu der in Fig. 3 und 3a dargestellten Zwischenposition simultan. Hier wird das zusÀtzliche Einzugelement 70 in eine Haltestellung gebracht, indem das Arretiersegment 80 von dem Schlitten 50 abgekoppelt wird und so keine weitere KraftÃŒbertragung auf das zusÀtzliche Einzugelement 70 stattfinden kann. Wie in Fig. 3a ersichtlich, erfolgt die Abkopplung durch das am GehÀuse 20 angebrachte Leitelement 28, auf welches das mit dem Schlitten in Bewegung befindliche Arretiersegment 80 mit der SchrÀge 84 auffÀhrt. Dabei wird das Arretiersegment 80 nach unten abgelenkt. So wird die kraftÃŒbertragende Anschlagverbindung zwischen dem Spannungsanschlag 55 und der GegenflÀche 831 des Arretiersegments 80 gelöst. Stattdessen wird das Arretiersegment 80 mit dem GehÀuse 20 in Anschlagverbindung gebracht, indem die Nase 85 ÃŒber das Ende des FÃŒhrungssteges 27 greift. Der FÃŒhrungssteg 27 ist derart dimensioniert, dass er in diesem Bereich endet und dessen Ende nun als AnschlagflÀche dient. Über diese Haltestellung des Arretiersegments 80 wird die nun komplett aufgeladene zusÀtzliche Einzugvorrichtung 70 unter Vorspannung gehalten. Die Einzugfeder 40 hingegen wird weiter mit der Öffnungsbewegung aufgeladen.If now in an opening movement of the driver 90 moves to the left, at the same time the feed spring 40 and the additional feed element 70 by the force that performs this movement, stretched. Thus, they are energetically charged, ie they store the energy supplied to them. According to the invention, the power transmission via the coupling element 60, which transmits the force on the carriage 50 to both the pull-in spring 40 and on the locking segment 80 and so on the additional clamping element 70. Charging takes place up to the in Fig. 3 and 3a represented intermediate position simultaneously. Here, the additional intake element 70 is brought into a holding position by the locking segment 80 is decoupled from the carriage 50 and so no further power transmission can take place on the additional intake element 70. As in Fig. 3a it can be seen, the decoupling is carried out by the guide member 28 mounted on the housing 20, on which the arresting segment 80 in motion with the carriage ascends with the bevel 84. In this case, the locking segment 80 is deflected downward. Thus, the force-transmitting stop connection between the voltage stop 55 and the counter surface 831 of the locking segment 80 is released. Instead, the locking segment 80 is brought into abutment with the housing 20 by the nose 85 engages over the end of the guide web 27. The guide web 27 is dimensioned such that it ends in this area and its end now serves as a stop surface. About this holding position of the locking segment 80, the now fully charged additional feeder 70 is held under tension. The retraction spring 40, however, is further charged with the opening movement.

Die Aufladung erfolgt bis zu der in Fig. 4 und 4a gezeigten Parkposition. Dabei wird das Koppelsegment 60 Ìber eine im Deckel des GehÀuses 20 befindliche FÌhrungskulisse, die hier nicht gezeigt ist, abgekippt. Auf diese Weise gibt sie den Mitnehmer 90 frei und die MöbeltÌr befindet sich im Freilauf. Das Koppelelement 60 ist arretiert und hÀlt die komplett gespannte Einzugfeder 40 unter Vorspannung. In der Parkposition ist somit die Einzugvorrichtung komplett aufgeladen.Charging takes place up to the in 4 and 4a shown parking position. In this case, the coupling segment 60 via a located in the cover of the housing 20 guide link, which is not shown here, tilted. In this way it releases the driver 90 and the furniture door is in freewheel. The coupling element 60 is locked and keeps the completely tensioned pull-in spring 40 under tension. In the parking position thus the feeder is completely charged.

In der Schließbewegung fÀngt zunÀchst das Koppelelement 60 den Mitnehmer 90 auf. Er wird durch dessen Aufprall aus der Parkposition gelenkt. Die Kraft der Einzugfeder 40, die in dieser Lage durch den weiten Spannweg verhÀltnismÀßig hoch ist, zieht den Mitnehmer 90 in Richtung geschlossenem Zustand der TÃŒr. Dabei wird die Bewegung durch die DÀmpfvorrichtung 30 abgedÀmpft, sodass eine harmonische Schließbewegung entsteht. WÀhrend des RÃŒckstellens in die Schließposition verkÃŒrzt sich die Einzugfeder 40 und die Schließkraft verringert sich. Bei Erreichen der Zwischenposition wird das Arretiersegment 80 von dem GehÀuse 20 gelöst. Dies geschieht ÃŒber das Steuerelement 56 des Schlittens 50, welches in der Schließbewegung auf die SteuerflÀche 832 auffÀhrt und so das Arretiersegment 80 aus der Anschlagverbindung mit dem GehÀuse 20 löst. Stattdessen bringt es das Arretiersegment 80 erneut mit dem Schlitten 50 in Anschlagverbindung. So wirkt nun eine ÃŒber das zusÀtzliche Einzugelement 70 aufgebrachte zusÀtzliche Einzugkraft auf den Schlitten 50, der diese ÃŒber das Koppelelment 60 auf den Mitnehmer 90 ÃŒbertrÀgt. Über die gesamte wirksame Einzugkraft wird die MöbeltÃŒr sicher in Schließstellung gebracht.In the closing movement, the coupling element 60 initially captures the catch 90. He is steered by the impact of the parking position. The force of the pull-in spring 40, which is relatively high in this position by the wide clamping path, pulls the cam 90 in the direction of the closed state of the door. The movement is damped by the damping device 30, so that a harmonious closing movement. During the return to the closed position, the retraction spring 40 shortens and the closing force decreases. Upon reaching the intermediate position, the locking segment 80 is released from the housing 20. This is done via the control element 56 of the carriage 50, which ascends in the closing movement on the control surface 832 and thus releases the locking segment 80 from the abutment connection with the housing 20. Instead, it brings the locking segment 80 again with the carriage 50 in abutment. Thus, an additional pull-in force applied via the additional pull-in element 70 now acts on the slide 50, which transmits it via the coupling element 60 to the catch 90. The furniture door is safely brought into the closed position over the entire effective pull-in force.

Fig. 5 verdeutlicht die Wirkung der Einzugkraft F Ìber dem Einzugweg x. Die von der Einzugfeder 40 aufgebrachte Einzugkraft F1 ist ab der Parkposition wirksam, wo ihr Betrag aufgrund des weiten Einzugweges x am höchsten ist. Mit sich verringerndem Einzugweg x reduziert sich die wirksame Kraft F1. Ab der Zwischenposition des Koppelelements 60 wird nun F2 durch das zusÀtzliche Einzugelement 70 hinzugeschaltet. Durch die Parallelschaltung addieren sich die KrÀfte zu einer gegenÌber F1 erhöhten Einzugkraft F1+F2. Fig. 5 illustrates the effect of the insertion force F on the pull-in x. The pull-in force F1 applied by the pull-in spring 40 is effective from the parking position, where its amount is highest due to the wide pull-in path x. With decreasing pull-in distance x, the effective force F1 is reduced. From the intermediate position of the coupling element 60 F2 is now connected by the additional feed element 70. Due to the parallel connection, the forces add up to an increased pull-in force F1 + F2 compared to F1.

Wie Fig. 6 verdeutlicht, kann nicht nur ein zusÀtzliches Einzugelement 70, sondern auch beispielsweise zwei in einer Einzugvorrichtung 1 vorgesehen sein. Hierbei ergeben sich zwei Zwischenpositionen, an denen jeweils ein zusÀtzliches Einzugelement 70 hinzugeschaltet wird. So addiert sich zu F1 zunÀchst eine zusÀtzliche Kraft F2 zur Einzugkraft F1+F2 und schließlich eine weitere Kraft F3 zur resultierenden Einzugkraft F1+F2+F3. Auch weitere zusÀtzliche Einzugvorrichtungen sind denkbar, die so in Art einer Kaskadenschaltung wirksam werden können. Auf diese Weise lÀsst sich in unterschiedlichen Bereichen des Einzugweges x eine optimierte Einzugbewegung ermöglichen, um so ein sicheres Schließen der MöbeltÃŒr bei hohem Bedienkomfort zu gewÀhrleisten.As Fig. 6 illustrates, not only an additional feed element 70, but also, for example, two may be provided in a feeder 1. This results in two intermediate positions at which an additional feed element 70 is connected in each case. Thus, an additional force F2 to the pull-in force F1 + F2 and finally another force F3 to the resulting pull-in force F1 + F2 + F3 are added to F1. Also, additional additional collection devices are conceivable, which can be effective in the manner of a cascade circuit. In this way, an optimized retraction movement can be made possible in different areas of the retraction path x in order to ensure a secure closing of the furniture door with a high degree of operating convenience.
