Description

Die vorliegende Erfindung bezieht sich auf eine Schubladenausziehführung, umfassend:

  • eine Korpusschiene, welche über einen Befestigungsabschnitt an einem Möbelkorpus zu montieren ist,
  • eine an einer Schublade zu befestigende Ladenschiene, welche relativ zur Korpusschiene verfahrbar gelagert ist, wobei die Ladenschiene einen dem Befestigungsabschnitt zugewandten Seitensteg aufweist,
  • eine Mittelschiene, welche zwischen der Korpusschiene und der Ladenschiene verfahrbar gelagert ist,
  • ein Lager mit zumindest einer Abstützrolle, über die sich die Ladenschiene im geschlossenen Zustand an der Korpusschiene abstützt, wobei das Lager an einem vorderen Endbereich der Mittelschiene oder der Ladenschiene angeordnet und in Längsrichtung jener Schiene, an der das Lager angeordnet ist, im Betrieb unverschiebbar angeordnet ist.
The present invention relates to a drawer extension guide comprising:
  • a carcass rail, which is to be mounted on a mounting portion on a furniture body,
  • a drawer rail to be fastened to a drawer rail, which is mounted to be movable relative to the carcass rail, the drawer rail having a fastening section facing the side web,
  • a middle rail, which is movably mounted between the carcass rail and the drawer rail,
  • a bearing with at least one support roller, via which the drawer rail is supported in the closed state on the carcass rail, wherein the bearing arranged at a front end portion of the center rail or the drawer rail and arranged immovably in the longitudinal direction of the rail on which the bearing is arranged, during operation is.

Im Weiteren betrifft die Erfindung eine Anordnung mit einer Schublade und mit einer Schubladenausziehführung der zu beschreibenden Art.Furthermore, the invention relates to an arrangement with a drawer and a drawer extension of the type to be described.

In der AT 4518 U1 und in der EP 1 470 770 A1 sind jeweils Schubladenausziehführungen beschrieben, wobei im vorderen Bereich der Korpusschiene ein Lager mit zumindest einer Abstützrolle angeordnet ist. Diese Abstützrolle ist dazu vorgesehen, dass die Ausziehschiene bzw. die damit verbundene Schublade im geschlossenen Zustand abgestützt wird. Die Abstützrolle liegt dabei an einem seitlichen Randbereich bzw. an einer Umbiegung der Ausziehschiene an. Durch die Abstützrolle werden die Wälzkörper von Laufwagen, welche zwischen den Schienen zur Übertragung der Last der Schublade verfahrbar gelagert sind, vom Gewicht der Schublade entlastet und folglich vor Deformation geschützt. Im Weiteren bewirkt die Abstützrolle, dass die Schublade im Schließzustand leicht angehoben wird und eine unerwünschte Absenkung der Schublade verhindert wird. Somit können die horizontal verlaufenden Fugen zwischen den Frontblenden von übereinander angeordneten Schubladen eines Schrankes eine konstante Breite aufweisen, sodass das von außen sichtbare Fugenbild auch optisch ansprechend ist.In the AT 4518 U1 and in the EP 1 470 770 A1 each drawer extension guides are described, wherein in the front region of the carcass rail, a bearing is arranged with at least one support roller. This support roller is provided so that the pull-out rail or the drawer connected thereto is supported in the closed state. The support roller lies against a lateral edge region or at a bend of the pull-out rail. By the support roller, the rolling elements of carriages, which are movably mounted between the rails for transmitting the load of the drawer, relieved of the weight of the drawer and thus protected from deformation. Furthermore, the support roller causes the drawer is slightly raised in the closed state and an undesirable lowering of the drawer is prevented. Thus, the horizontally extending joints between the front panels of superposed drawers of a Cabinet have a constant width, so that the visible from the outside joint image is also visually appealing.

Schubladenausziehführungen mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 gehen aus der EP 0 834 270 A2 , aus der EP 1 190 646 A1 , aus der EP 0 664 983 A2 , aus der EP 0 656 182 A1 sowie aus der DE 20 2008 017 061 U1 hervor.Drawer pull-outs with the features of the preamble of claim 1 go from the EP 0 834 270 A2 , from the EP 1 190 646 A1 , from the EP 0 664 983 A2 , from the EP 0 656 182 A1 as well as from the DE 20 2008 017 061 U1 out.

Aufgabe der vorliegenden Erfindung ist es, eine Schubladenausziehführung der eingangs erwähnten Gattung mit einer kompakteren Bauweise anzugeben.Object of the present invention is to provide a drawer extension of the type mentioned with 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 vorgesehen, dass die Mittelschiene einen dem Seitensteg der Ladenschiene zugewandten seitlichen Profilabschnitt aufweist, wobei der seitliche Profilabschnitt der Mittelschiene zwischen der Abstützrolle und dem Seitensteg der Ladenschiene angeordnet ist.According to the invention, it is provided that the middle rail has a side profile section facing the side web of the drawer rail, wherein the lateral profile section of the middle rail is arranged between the support roller and the side web of the drawer rail.

Mit anderen Worten wird die Abstützrolle im Vergleich zum genannten Stand der Technik zentraler im Schienensystem der Schubladenausziehführung angeordnet, wobei der Raum zwischen einem Seitensteg der Ladenschiene und dem Möbelkorpus verkleinert und die Schubladenausziehführung insgesamt schmaler ausgeführt werden kann.In other words, in comparison to the cited prior art, the support roller is arranged more centrally in the rail system of the drawer extension guide, whereby the space between a side web of the drawer rail and the furniture carcass can be reduced and the drawer extension guide as a whole can be made narrower.

Durch eine mittige Anordnung der Abstützrolle im Führungssystem erhält man auch eine zentrale Lastverteilung, wobei die zumindest eine Abstützrolle zwischen benachbarten und zueinander beweglichen Schienen der Schubladenausziehführung in einem vergleichsweise engen Zwischenbereich platzsparend untergebracht werden kann. Anders als beim genannten Stand der Technik, bei der die Abstützrolle seitlich gelagert ist, wird bei der erfindungsgemäßen Konstruktion zudem kein seitliches Kippmoment auf die zwischen den Schienen befindlichen Laufwagen ausgeübt, sodass die Laufwagen weitgehend vertikal belastet werden und keine Verwindung der Schubladenausziehführung herbeigeführt wird.By a central arrangement of the support roller in the guide system also gives a central load distribution, wherein the at least one support roller between adjacent and mutually movable rails of the drawer extension guide can be accommodated in a space-saving comparatively narrow intermediate area. Unlike the cited prior art, in which the support roller is mounted laterally, in the construction according to the invention also no lateral tilting moment is exerted on the carriage located between the rails, so that the carriages are largely loaded vertically and no distortion of the drawer extension guide is brought about.

Überdies ist es nicht mehr zwingend erforderlich, die Ladenschiene mit einer Umbiegung zu versehen, durch welche die Ladenschiene an der Abstützrolle abstützbar ist, weil bei der erfindungsgemäßen Ausgestaltung die Abstützrolle direkt mit den Laufstegen der Schienen zusammenwirken kann.Moreover, it is no longer absolutely necessary to provide the drawer rail with a bend, through which the drawer rail can be supported on the support roller, because in the embodiment according to the invention the support roller can interact directly with the catwalks of the rails.

Die Ladenschiene kann einen durch das Schienenprofil der Ladenschiene begrenzten Hohlraum aufweisen, wobei die Abstützrolle innerhalb dieses Hohlraumes angeordnet ist. Hierbei kann es günstig sein, wenn die Ladenschiene zwei Seitenstege und einen die Seitenstege verbindenden, vorzugsweise flächen, Mittelsteg aufweist, wobei die Abstützrolle vollständig innerhalb der beiden Seitenstege der Ladenschiene angeordnet ist. Die Abstützrolle kann dabei einerseits mit der Unterseite des Mittelsteges der. Ladenschiene, andererseits mit einem Laufsteg der Korpusschiene zusammenwirken.The drawer rail may have a cavity bounded by the rail profile of the drawer rail, the support roller being disposed within this cavity. In this case, it may be favorable if the drawer rail has two side webs and a middle web connecting the side webs, preferably surfaces, wherein the support roller is arranged completely within the two side webs of the drawer rail. The support roller can on the one hand with the underside of the central web of the. Store rail, on the other hand interact with a catwalk of the carcass rail.

Das Lager mit der Abstützrolle kann beispielsweise an der Ladenschiene angeordnet sein, wobei die Abstützrolle im Schließzustand der Ladenschiene mit der Korpusschiene zusammenwirkt.The bearing with the support roller can be arranged for example on the drawer rail, wherein the support roller cooperates in the closed state of the drawer rail with the carcass rail.

Bei einem Vollauszug ist üblicherweise vorgesehen, dass die Schubladenausziehführung eine zwischen der Korpusschiene und der Ausziehschiene verschiebbar gelagerte Mittelschiene aufweist. Hierbei kann das Lager mit der Abstützrolle an der Mittelschiene gelagert sein, wobei die Abstützrolle einerseits mit der Korpusschiene, andererseits mit der Ladenschiene zusammenwirkt.In a full extension is usually provided that the drawer extension has a displaceably mounted between the carcass rail and the pull-down middle rail. Here, the bearing may be mounted with the support roller on the center rail, wherein the support roller cooperates on the one hand with the carcass rail, on the other hand with the drawer rail.

Die Abstützrolle ist an einem vorderen Endbereich der Mittelschiene oder an einem vorderen Endbereich der Ladenschiene angeordnet, wobei die Abstützrolle drehbar, jedoch in Längsrichtung jener Schiene, an der das Lager angeordnet ist, im Betrieb (d.h. bei einer Relativbewegung der Schienen 5, 7, 8 zueinander) unverschiebbar angeordnet. Als "vorderer Endbereich der Schiene" ist jeweils das vorderste Drittel der Länge der Mittelschiene oder das vorderste Drittel der Ladenschiene in Montagelage zu verstehen.The support roller is arranged at a front end region of the middle rail or at a front end region of the drawer rail, wherein the support roller rotatably, but in the longitudinal direction of the rail on which the bearing is arranged in operation (ie, during a relative movement of the rails 5, 7, 8 mutually) immovably arranged. As the "front end portion of the rail" is in each case the foremost third of Length of the center rail or the foremost third of the drawer rail to understand in mounting position.

Durch die Anordnung des Lagers mit der Abstützrolle an der Mittelschiene oder an der Ladenschiene kann eine Verklemmung von Laufwagen bzw. von Wälzkörpern - welche üblicherweise zwischen den Schienen der Schubladenausziehführung verschiebbar gelagert sind - weitgehend vermieden werden, wodurch der Lauf der Schubladenausziehführung verbessert wird.The arrangement of the bearing with the support roller on the center rail or on the drawer rail jamming of carriage or rolling elements - which are usually slidably mounted between the rails of Schubladenausziehführung - largely avoided, whereby the run of the drawer extension guide is improved.

Fig. 2b zeigt den vorderen Endbereich der Schubladenausziehführung 4 in einer vergrößerten Darstellung. Über eine Höhenverstellvorrichtung 14 ist der vordere Endbereich der Schublade 3 anhebbar und absenkbar. Die Höhenverstellvorrichtung 14 umfasst ein manuell zu betätigendes Griffteil 15 mit einem damit verbundenen Lagerteil 16, an dem in Montagelage ein seitlicher Randbereich der Schublade 3 aufliegt. Der Griffteil 15 kann an mehreren vorgegebenen Rasten 18 der Ladenschiene 8 positioniert werden, wobei der Lagerteil 16 (und damit der vordere Endbereich einer Schublade 3) je nach Wahl einer Raste 18 eine unterschiedliche Höhenposition einnimmt. Fig. 2b shows the front end portion of the drawer extension guide 4 in an enlarged view. About a height adjustment device 14, the front end portion of the drawer 3 is raised and lowered. The height adjustment device 14 comprises a manually operable grip part 15 with a bearing part 16 connected thereto, on which in the mounting position a lateral edge region of the drawer 3 rests. The grip part 15 can be positioned at a plurality of predetermined detents 18 of the drawer rail 8, whereby the bearing part 16 (and thus the front end area of a drawer 3) assumes a different height position depending on the choice of a detent 18.

Fig. 3a zeigt den vorderen Endbereich der Schubladenausziehführung 4 in einer perspektivischen Ansicht. Die Korpusschiene 5 weist einen Befestigungsabschnitt 6 zur Montage am Möbelkorpus 2 sowie einen Horizontalsteg 19 auf, an dem sich die Abstützrolle 12 in der Schließstellung der Ladenschiene 8 abstützt. Im gezeigten Ausführungsbeispiel ist das Lager 11 mit der Abstützrolle 12 an der Mittelschiene 7 befestigt, wobei die Abstützrolle 12 einerseits mit der Unterseite eines Mittelsteges 22 der Ladenschiene 8 und andererseits mit dem Horizontalsteg 19 der Korpusschiene 5 zusammenwirkt. Die Ladenschiene 8 weist einen dem Befestigungsabschnitt 6 zugewandten Seitensteg 20 auf, wobei der Seitensteg 20 der Ladenschiene 8 zwischen der Abstützrolle 12 und dem Befestigungsabschnitt 6 der Korpusschiene 5 angeordnet ist. Die Ladenschiene 8 weist zwei Seitenstege 20, 21 und einen die Seitenstege 20, 21 verbindenden, vorzugsweise flachen, Mittelsteg 22 auf, wobei die Abstützrolle 12, vorzugsweise vollständig, innerhalb der beiden Seitenstege 20, 21 der Ladenschiene 8 angeordnet ist. Über das Griffteil 15 der Höhenverstellvorrichtung 14 ist der Lagerteil 16, an dem der vordere Endbereich der Schublade 3 aufliegt, höhenverstellbar ausgebildet. Fig. 3a shows the front end portion of the drawer pull-out guide 4 in a perspective view. The carcass rail 5 has a mounting portion 6 for mounting on the furniture body 2 and a horizontal web 19 on which the support roller 12 is supported in the closed position of the drawer rail 8. In the illustrated embodiment, the bearing 11 is fixed to the support roller 12 on the center rail 7, wherein the support roller 12 on the one hand with the underside of a central web 22 of the drawer rail 8 and on the other hand with the horizontal web 19 of the carcass rail fifth interacts. The drawer rail 8 has a side web 20 facing the fastening section 6, wherein the side web 20 of the drawer rail 8 is arranged between the support roller 12 and the fastening section 6 of the carcass rail 5. The drawer rail 8 has two side webs 20, 21 and a side web 20, 21 connecting, preferably flat, central web 22, wherein the support roller 12, preferably completely, within the two side webs 20, 21 of the drawer rail 8 is arranged. The bearing part 16, on which the front end area of the drawer 3 rests, is designed to be height-adjustable via the grip part 15 of the height adjustment device 14.

Fig. 3b zeigt die Schubladenausziehführung 4 gemäß Fig. 3a in einem Vertikalschnitt. Die Ladenschiene 8 weist einen durch das Schienenprofil der Ladenschiene 8 begrenzten Hohlraum auf, wobei die Abstützrolle 12, vorzugsweise vollständig, innerhalb dieses Hohlraumes angeordnet ist. Die Ladenschiene 8 ist nach unten zumindest teilweise offen ausgebildet. Durch die zentrale Anordnung der Abstützrolle 12 zwischen zueinander beweglichen Schienen 5, 7, 8 der Schubladenausziehführung 4 kann die Abstützrolle 12 in einem vergleichsweise engen Zwischenbereich platzsparend untergebracht werden, wobei der Raum 23 zwischen dem Seitensteg 20 der Ladenschiene 8 und dem Befestigungsabschnitt 6 der Korpusschiene 5 verkleinert und die Schubladenausziehführung 4 insgesamt schmaler und folglich kompakter ausgeführt werden kann. Fig. 3b shows the drawer pull-out guide 4 according to Fig. 3a in a vertical section. The drawer rail 8 has a limited by the rail profile of the drawer rail 8 cavity, wherein the support roller 12, preferably completely, is disposed within this cavity. The drawer rail 8 is formed downwardly at least partially open. Due to the central arrangement of the support roller 12 between mutually movable rails 5, 7, 8 of the drawer extension guide 4, the support roller 12 can be accommodated in a comparatively narrow intermediate space to save space, the space 23 between the side web 20 of the drawer rail 8 and the mounting portion 6 of the carcass rail fifth reduced and the drawer pull-out 4 overall narrower and therefore can be made more compact.

Fig. 4a zeigt den vorderen Endbereich der Schubladenausziehführung 4 in einer leicht abgewandelten Ausführungsform. Das Lager 11 mit der Abstützrolle 12 ist über den Schnappverbinder 13 an der Mittelschiene 7 gelenkig befestigt. Im gezeigten Ausführungsbeispiel weist die Mittelschiene 7 einen Horizontalsteg 27 auf, an dessen vorderen Ende eine in Längsrichtung des Horizontalsteges 27 verlaufende und nach vorne hin offene Aussparung 25 angeordnet ist. Die Aussparung 25 ist zur Aufnahme der Abstützrolle 12 vorgesehen. Die Ladenschiene 8 weist im vorderen Endbereich eine Erhöhung 24, vorzugsweise in Form einer Prägung, auf, welche im Schließzustand der Ladenschiene 8 mit der Abstützrolle 12 zusammenwirkt. Durch die Erhöhung 24 kann die Ladenschiene 8 im Schließzustand auf ein definiertes Maß angehoben werden, wobei eine unerwünschte Absenkung einer schwer beladenen Schublade 3 weitgehend verhindert werden kann. Eine weitere Funktion der Erhöhung 24 besteht darin, dass sich die Ladenschiene 8 im Schließzustand zwar über diese Erhöhung 24 an der Abstützrolle 12 abstützt, beim Öffnen der Ladenschiene 8 (welche sich bei einem Differentialauszug mit etwa der doppelten Geschwindigkeit als die Mittelschiene 7 bewegt) wird die Abstützrolle 12 von der Ladenschiene 8 jedoch sofort freigestellt, woraufhin die Last der Schublade 3 ausschließlich von (nicht dargestellten) Laufwagen mit Wälzkörpern, welche üblicherweise zwischen den Schienen 5, 7, 8 der Schubladenausziehführung 4 verfahrbar gelagert sind, übertragen wird. Auf diese Weise können die Laufkräfte der Schubladenausziehführung 4 verringert werden. Fig. 4a shows the front end portion of the drawer pull-out guide 4 in a slightly modified embodiment. The bearing 11 with the support roller 12 is hingedly attached via the snap connector 13 to the center rail 7. In the exemplary embodiment shown, the middle rail 7 has a horizontal web 27, at the front end of which a recess 25 extending in the longitudinal direction of the horizontal web 27 and open towards the front is arranged. The recess 25 is provided for receiving the support roller 12. The drawer rail 8 has in the front end region an elevation 24, preferably in the form of an embossment, which cooperates with the support roller 12 in the closed state of the drawer rail 8. By increasing 24, the drawer rail 8 can be raised in the closed state to a defined level, with an unwanted lowering of a heavily loaded drawer 3 largely can be prevented. Another function of the elevation 24 is that the drawer rail 8 is supported in the closed state via this increase 24 on the support roller 12, when opening the drawer rail 8 (which moves at a differential extension at about twice the speed than the center rail 7) However, the support roller 12 of the drawer rail 8 but immediately released, whereupon the load of the drawer 3 exclusively by (not shown) carriage with rolling elements, which are usually mounted between the rails 5, 7, 8 of the drawer extension guide 4, is transmitted. In this way, the running forces of the drawer extension guide 4 can be reduced.

Fig. 4b zeigt die Ausführungsform der Schubladenausziehführung 4 gemäß Fig. 4a in einem Vertikalschnitt. Zu erkennen ist, dass die Abstützrolle 12 bei geschlossener Ladenschiene 8 einerseits mit der Erhöhung 24 der Ladenschiene 8, andererseits mit dem Horizontalsteg 19 der Korpusschiene 5 zusammenwirkt. Die Mittelschiene 7 weist einen dem Seitensteg 20 der Ladenschiene 8 zugewandten seitlichen Profilabschnitt 26 auf, wobei der seitliche Profilabschnitt 26 der Mittelschiene 7 zwischen der Abstützrolle 12 und dem Seitensteg 20 der Ladenschiene 8 angeordnet ist. Bei dieser Ausführungsform befinden sich also sowohl der seitliche Profilabschnitt 26 der Mittelschiene 7 als auch der Seitensteg 20 der Ladenschiene 8 zwischen der Abstützrolle 12 und dem Befestigungsabschnitt 6 der Korpusschiene 5. Die Abstützrolle 12 steht nach oben und unten über den Horizontalsteg 27 der Mittelschiene 7 vor. Fig. 4b shows the embodiment of the drawer pull-out guide 4 according to Fig. 4a in a vertical section. It can be seen that the support roller 12 cooperates with closed loading rail 8 on the one hand with the increase 24 of the drawer rail 8, on the other hand with the horizontal web 19 of the carcass rail 5. The middle rail 7 has a side profile section 26 facing the side web 20 of the drawer rail 8, wherein the lateral profile section 26 of the middle rail 7 is arranged between the support roller 12 and the side web 20 of the drawer rail 8. In this embodiment, therefore, both the lateral profile section 26 of the middle rail 7 and the side web 20 of the drawer rail 8 between the support roller 12 and the mounting portion 6 of the carcass rail 5. The support roller 12 projects up and down over the horizontal web 27 of the center rail 7 ,

Fig. 5a zeigt den vorderen Endbereich der Schubladenausziehführung 4, wobei das Lager 11 mit der Abstützrolle 12 - im Unterschied zum vorherigen Ausführungsbeispiel - an der Ladenschiene 8 angeordnet ist. Das Lager 11 ist mit der Unterseite des Mittelsteges 22 der Ladenschiene 8 verbunden, beispielsweise verschweißt oder vernietet. Das Lager 11 mit der Abstützrolle 12 ist am vorderen Endbereich der Ladenschiene 8 angeordnet, wobei die Abstützrolle 12 gegen Ende der Schließbewegung der Ladenschiene in eine nach vorne hin offene Aussparung 25 der Mittelschiene 7 einfahren kann, wobei die Abstützrolle 12 bei geschlossener Ladenschiene 8 in der Aussparung 25 der Mittelschiene 7 aufgenommen ist. Fig. 5a shows the front end portion of the drawer extension guide 4, wherein the bearing 11 with the support roller 12 - in contrast to the previous embodiment - is arranged on the drawer rail 8. The bearing 11 is connected to the underside of the central web 22 of the drawer rail 8, for example, welded or riveted. The bearing 11 with the support roller 12 is disposed at the front end portion of the drawer rail 8, wherein the support roller 12 can retract towards the end of the closing movement of the drawer rail in a forwardly open recess 25 of the center rail 7, wherein the support roller 12 with closed drawer rail 8 in the Recess 25 of the middle rail 7 is added.

Fig. 5b zeigt die Ausführungsform gemäß Fig. 5a in einem Vertikalschnitt. Das Lager 11 weist hierbei einen ortsfesten, horizontal verlaufenden Achszapfen 28 auf, wobei die Abstützrolle 12 an diesem Achszapfen 28 drehbar gelagert ist. In der Schließstellung der Schubladenausziehführung 4 wirkt die Abstützrolle 12 einerseits mit der Unterseite des Mittelsteges 22 der Ladenschiene 8, andererseits mit dem Horizontalsteg 19 der Korpusschiene 5 zusammen. Der dem Seitensteg 20 der Ladenschiene 8 zugewandte seitliche Profilabschnitt 26 der Mittelschiene 7 ist zwischen der Abstützrolle 12 und dem Seitensteg 20 der Ladenschiene 8 angeordnet. Fig. 5b shows the embodiment according to Fig. 5a in a vertical section. The bearing 11 in this case has a stationary, horizontally extending axle journal 28, wherein the support roller 12 is rotatably mounted on this axle journal 28. In the closed position of the drawer extension guide 4, the support roller 12 acts on the one hand with the underside of the central web 22 of the drawer rail 8, on the other hand with the horizontal web 19 of the carcass rail 5 together. The side profile section 26 of the middle rail 7 facing the side web 20 of the drawer rail 8 is arranged between the support roller 12 and the side web 20 of the drawer rail 8.

Fig. 6a zeigt ein mögliches Ausführungsbeispiel eines Lagers 11 in einer perspektivischen Ansicht. Das Lager 11 ist über einen Schnappverbinder 13, vorzugsweise gelenkig, an der Mittelschiene 7 oder an der Ladenschiene 8 der Schubladenausziehführung 4 zu befestigen. Der Schnappverbinder 13 weist zwei federnd ausgebildete Arretierelemente 30 auf, welche in Montagelage die am Lager 11 ausgebildeten Vorsprünge 31 formschlüssig umgreifen. Das Lager 11 weist zudem einen federnd ausgebildeten Arm 32 auf, wobei sich das freie Ende des Armes 32 in Montagelage an jener Schiene 7 und 8, an der das Lager 11 angeordnet ist, abstützt. Durch den federnden Arm 32 können in Höhenrichtung auftretende Toleranzen der Schubladenausziehführung 4 weitgehend kompensiert werden. Das Lager 11 umfasst eine Führung 29, welche die Abstützrolle 12 allseitig umgibt und in welcher die Abstützrolle 12 lose aufgenommen ist. Durch die Führung 29 ist die Abstützrolle 12 begrenzt höhenbeweglich gelagert. Diese Lagerung der Abstützrolle 12 in vertikaler Richtung kann dadurch erreicht werden, indem zumindest ein Achszapfen 28 des Lagers 11 in eine - vorzugsweise nicht durchgehende - Ausnehmung 33 der Abstützrolle 12 ragt, wobei der Durchmesser der Ausnehmung 33 größer als der Durchmesser des Achszapfens 28 ist. Die Abstützrolle 12 weist somit keine feststehende, sondern eine höhenbewegliche Drehachse auf. Auf diese Weise können zusätzliche Toleranzen des Führungssystems aufgenommen werden. Fig. 6a shows a possible embodiment of a bearing 11 in a perspective view. The bearing 11 is to be attached via a snap connector 13, preferably articulated, to the middle rail 7 or to the drawer rail 8 of the drawer pull-out guide 4. The snap connector 13 has two resiliently formed locking elements 30, which engage in a form-fitting manner in the mounting position formed on the bearing 11 projections 31. The bearing 11 also has a spring-trained arm 32, wherein the free end of the arm 32 in the mounting position on that rail 7 and 8, on which the bearing 11 is arranged, is supported. By the resilient arm 32 occurring tolerances of the drawer extension guide 4 can be largely compensated. The bearing 11 comprises a guide 29, which surrounds the support roller 12 on all sides and in which the support roller 12 is loosely received. By the guide 29, the support roller 12 is mounted limited height adjustable. This support of the support roller 12 in the vertical direction can be achieved by at least one journal 28 of the bearing 11 protrudes into a - preferably non-continuous - recess 33 of the support roller 12, wherein the diameter of the recess 33 is greater than the diameter of the journal 28. The support roller 12 thus has no fixed, but a height-adjustable axis of rotation. In this way, additional tolerances of the guide system can be added.

Fig. 6b zeigt das Lager 11 mit der in der Führung 29 eingesetzten Abstützrolle 12 und montiertem Schnappverbinder 13, wobei die Arretierelemente 30 des Schnappverbinders 13 die Vorsprünge 31 formschlüssig umgreifen. Fig. 6b shows the bearing 11 with the support roller 12 inserted in the guide 29 and mounted snap connector 13, wherein the locking elements 30 of the snap connector 13 engage around the projections 31 in a form-fitting manner.

Fig. 6c zeigt das Lager 11 in einem perspektivischen Schnitt. Die Abstützrolle 12 ist durch beidseitig an der Führung 29 angeordnete Achszapfen 28, welche jeweils in eine als Sackloch ausgebildete Ausnehmung 33 der Abstützrolle 12 hineinragen, höhenbeweglich gehalten. Das Lager 11 ist einstückig ausgebildet und kann in einfacher Weise durch ein Spritzgussverfahren aus einem Kunststoffmaterial hergestellt werden. Die Abstützrolle 12 kann ebenfalls aus Kunststoff oder aus Metall bestehen. Bei einer Ausführung der Abstützrolle 12 aus Metall kann eine Kunststoffummantelung zweckmäßig sein. Die Abstützrolle 12 kann bei allen Ausführungsbeispielen kugelförmig, zylindrisch, scheibenförmig oder kegelstumpfförmig ausgebildet sein. Selbstverständlich können auch zwei oder mehrere Abstützrollen 12 vorgesehen werden, welche seitlich nebeneinander, vorzugsweise an einer gemeinsamen Achse, angeordnet sind oder auch derart, dass die Abstützrollen 12 in Verfahrrichtung der Ladenschiene 8 hintereinander angeordnet sind. Fig. 6c shows the bearing 11 in a perspective section. The support roller 12 is held by both sides of the guide 29 axle journals 28, which each protrude into a formed as a blind hole recess 33 of the support roller 12, held vertically movable. The bearing 11 is integrally formed and can be easily manufactured by an injection molding of a plastic material. The support roller 12 may also be made of plastic or metal. In one embodiment of the support roller 12 made of metal, a plastic jacket may be appropriate. The support roller 12 may be spherical, cylindrical, disc-shaped or frustoconical in all embodiments. Of course, two or more support rollers 12 may be provided, which are arranged side by side, preferably on a common axis, or even such that the support rollers 12 are arranged in the direction of travel of the drawer rail 8 in a row.
