Description

Ausziehführung für Schubladen Pull-out guide for drawers

Die vorliegende Erfindung bezieht sich auf eine Ausziehführung für Schubladen mit einer ersten und mit wenigstens einer zweiten Schiene, wobei zwischen diesen beiden Schienen wenigstens ein Laufwagen angeordnet ist, der eine Lagergruppe mit lastübertragenden Elementen, vorzugsweise Rollen, Wälzkörper und/oder Kugeln, angeordnet ist, wobei die lastübertragenden Elemente die Lagergruppe sowohl in vertikaler als auch in horizontaler Richtung führen.The present invention relates to a pull-out guide for drawers with a first and at least one second rail, wherein between these two rails at least one carriage is arranged, which is a bearing group with load-transferring elements, preferably rollers, rolling elements and / or balls, arranged wherein the load-transferring elements guide the storage group in both vertical and horizontal directions.

Im Weiteren bezieht sich die Erfindung auf einen Laufwagen einer derartigen Ausziehführung sowie auf ein Möbel mit einer Ausziehführung der vorstehend genannten Art.Furthermore, the invention relates to a carriage such a pull-out as well as a piece of furniture with a pull-out of the aforementioned type.

Derartige Ausziehführungen für Schubladen können sowohl als Einzelauszug mit einer korpusseitigen Tragschiene und einer ladenseitigen Ausziehschiene an jeder Schubladenseite ausgeführt sein oder auch als Vollauszug, bei dem zwischen den Ausziehschienen und den Tragschienen jeweils eine Mittelschiene angeordnet ist. Die Ausziehführungen ermöglichen einen ruhigen Lauf der Schublade oder eines Fachbodens bei gleichzeitiger hoher Lastaufnahme derselben. Im Schließzustand der Schublade, insbesondere bei hoher Lastaufnahme, werden die vordersten lastübertragenden Elemente des zwischen den Schienen verfahrbaren Laufwagens erheblich belastet. Werden als lastübertragende Elemente Kunststoffrollen verwendet, so können sich diese Rollen mit der Zeit verformen und dadurch das Laufverhalten der Ausziehführung nachteilig beeinträchtigen.Such pull-out guides for drawers can be designed as a single drawer with a body-side mounting rail and a loading-side pull-out on each drawer side or as a full extension, in which between the pull-out rails and the support rails each have a center rail is arranged. The pull-out guides allow a smooth running of the drawer or shelf with simultaneous high load capacity. In the closed state of the drawer, especially at high load bearing, the foremost load-transferring elements of the movable carriage between the rails are significantly burdened. If plastic rollers are used as the load-transmitting elements, then these rollers may deform over time and adversely affect the running behavior of the pull-out guide.

Aus der AT 365 433 ist eine Vollauszugsführung für Schubladen bekannt geworden, wobei zwischen der korpusseitigen Tragschiene und der Mittelschiene ein Laufwagenkäfig angeordnet ist. Bei der Verschiebebewegung der Schienen ist ein dem Laufwagenkäfig zugeordneter Wälzkörper über das Ende der Tragschiene hinweg bewegbar.From AT 365 433 a full extension guide for drawers has become known, wherein between the body-side mounting rail and the center rail a carriage cage is arranged. During the sliding movement of the rails, a rolling element assigned to the carriage cage can be moved beyond the end of the mounting rail.

Die US 3,937,531 zeigt einen Teleskopauszug für Schubladen, wobei zwischen den Schienen ein Rollengleitlager angeordnet ist. In der Schließstellung der Schienen liegen alle Rollen an der Tragschiene an, bei der Öffnungsbewegung können einige Rollen von der Tragschiene außer Eingriff gebracht werden.The US 3,937,531 shows a telescopic extension for drawers, wherein between the rails a roller bearing is arranged. In the closed position of the rails all rollers are on the mounting rail, in the opening movement, some rollers can be disengaged from the mounting rail.

Aufgabe der vorliegenden Erfindung ist es daher, eine Ausziehführung der eingangs erwähnten Gattung mit einer längeren Lebensdauer bzw. Funktionalität vorzuschlagen. Dies wird erfindungsgemäß in einer vorteilhaften Ausgestaltung dadurch erreicht, dass wenigstens ein zusätzliches lastübertragendes Element vorgesehen ist, das an einem Ausleger mit Abstand von der Lagergruppe angeordnet ist, wobei das zusätzliche lastübertragende Element beim Ausziehen der zweiten Schiene zumindest bereichsweise über das Ende der ersten Schiene hinausfahrbar ist, sodass dieses nicht mehr an der ersten Schiene anliegt.Object of the present invention is therefore to propose a pull-out of the type mentioned above with a longer life or functionality. This is inventively achieved in an advantageous embodiment in that at least one additional load-transmitting element is provided, which is arranged on a boom at a distance from the bearing group, wherein the additional load-transmitting element at least partially extendable beyond the end of the first rail when extending the second rail is, so that it no longer rests on the first rail.

Diese bei der Bewegung des Schienensystems über das Ende der ersten Schiene hinausfahrbaren zusätzlichen lastübertragenden Elemente (die günstigerweise als vorderste lastübertragende Elemente des Laufwagens in Ausziehrichtung der Schienen angeordnet sind) dienen vorzugsweise nur der Abstützung der Schublade in deren Schließstellung, sodass diese im geschlossenen Zustand der Schublade am stärksten belastet werden und damit zumindest teilweise die Last von den anderen lastübertragenden Elementen (die als eigentliche Wälzkörper während der Verschiebebewegung der Schienen dienen) nehmen. Neben einer verbesserten Lastverteilung wird dabei erreicht, dass diese hinausfahrbaren zusätzlichen lastübertragenden Elemente zwar mit der Zeit abgeplattet bzw. verformt werden können, was aber letztlich unerheblich ist, da diese beim Bewegen der Schublade nicht mehr als eigentliche Wälzkörper der Ausziehführung in Funktion treten. In diesem Zusammenhang kann es also günstig sein, wenn sich das wenigstens eine lastübertragende Element im Schließzustand der Schienen an der ersten Schiene abstützt und in einer Offenstellung der zweiten Schiene von der ersten Schiene außer Eingriff ist.These in the movement of the rail system beyond the end of the first rail extendable additional load-transferring elements (which are conveniently arranged as the front load-transferring elements of the carriage in the direction of withdrawal of the rails) are preferably only the support of the drawer in its closed position, so that in the closed state of the drawer be loaded the strongest and thus at least partially take the load of the other load-transmitting elements (which serve as actual rolling elements during the sliding movement of the rails). In addition to an improved load distribution is achieved that these extendable additional load-transferring elements may indeed be flattened or deformed over time, but this is ultimately irrelevant, since these no longer occur as the actual rolling elements of the pull-out during movement of the drawer in function. In this context, it may thus be advantageous if the at least one load-transmitting element is supported on the first rail in the closed state of the rails and is disengaged from the first rail in an open position of the second rail.

Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass der Ausleger in axialer Richtung des Laufwagens und in Ausziehrichtung der Schienen angeordnet ist.According to a preferred embodiment of the invention can be provided that the boom is arranged in the axial direction of the carriage and in the withdrawal direction of the rails.

Gemäß dem Aspekt der vorliegenden Erfindung wird quasi ein standardmäßiger Laufwagenkäfig mit einem in axialer Richtung des Laufwagens weisenden Ausleger versehen. Da durch diese Konstruktion auch der Achsabstand zwischen der vordersten Achse und der hintersten Achse der Wälzkörper des Laufwagens erhöht wird, kann zudem eine verbesserte Lastverteilung der Schublade herbeigeführt werden. Gemäß einem weiteren Ausführungsbeispiel der Erfindung kann auch vorgesehen sein, dass der Ausleger auch mittels einer lösbaren Befestigungsvorrichtung an den Laufwagenkäfig gekoppelt ist (z.B. mit einem Kupplungsteil), sodass gegebenenfalls Ausleger verschiedener Länge mit einem Laufwagenkäfig gekoppelt werden können. Weitere Einzelheiten der Erfindung werden anhand der nachstehenden Figurenbeschreibung erläutert. Darin zeigt bzw. zeigen:According to the aspect of the present invention, a standard carriage cage is provided with a pointing in the axial direction of the carriage boom. Since this construction also increases the center distance between the foremost axis and the rearmost axis of the rolling elements of the carriage, an improved load distribution of the drawer can also be brought about. According to a further embodiment of the invention can also be provided that the boom is also coupled by means of a releasable fastening device to the carriage cage (eg with a coupling part), so that, where appropriate, boom of different lengths can be coupled to a carriage cage. Further details of the invention will be explained with reference to the following description of the figures. It shows or shows:

Fig. 1 zeigt ein schrankförmiges Möbel 1 mit einem Möbelkorpus 2, zu dem Schubladen 3a und 3b über erfindungsgemäße Ausziehführungen 4 verschiebbar geführt sind. Die Ausziehführungen 4 werden vorzugsweise auf beiden gegenüberliegenden Seitenwänden 5 des Möbelkorpus 2 befestigt und können sowohl als Einfachauszug mit einer ersten Schiene 6 und einer zweiten Schiene 7 oder auch als Differentialauszug mit drei Schienen ausgeführt sein, wobei die dargestellte Schiene 7 die Funktion der Mittelschiene übernimmt, die zwischen der korpusfesten ersten Schiene 6 und einer schubladenseitigen Ausziehschiene verschiebbar geführt ist.Fig. 1 shows a cupboard-shaped furniture 1 with a furniture body 2, to the drawers 3a and 3b are guided slidably over inventive pull-4. The extension guides 4 are preferably mounted on both opposite side walls 5 of the furniture body 2 and can be designed both as a single extension with a first rail 6 and a second rail 7 or as a differential extension with three rails, the illustrated rail 7 takes over the function of the center rail, which is guided displaceably between the body-fixed first rail 6 and a drawer-side pull-out rail.

Fig. 2 zeigt eine erfindungsgemäße Ausziehführung 4 für Schubladen 3a und 3b, wobei die erste Schiene 6 die korpusfeste Tragschiene darstellt und die zweite Schiene 7 der Schublade 3a oder 3b zugehörig ist. Die zweite Schiene 7 ist relativ zur ersten Schiene 6 verschiebbar gelagert. Die erste Schiene 6 weist einen Laufsteg 6a auf, an dem ein noch zu beschreibender Laufwagen zur Anlage bringbar ist. Die dargestellte Ausziehführung 4 befindet sich in der gezeigten Figur in einer Offenstellung.Fig. 2 shows a pull-out guide 4 according to the invention for drawers 3a and 3b, wherein the first rail 6 is the corpusfeste support rail and the second rail 7 of the drawer 3a or 3b is associated. The second rail 7 is displaceably mounted relative to the first rail 6. The first rail 6 has a catwalk 6a on which a carriage to be described can be brought into abutment. The pull-out guide 4 shown is in the figure shown in an open position.

Fig. 3 zeigt ein Ausführungsbeispiel eines Laufwagens 8 gemäß dem Aspekt der Erfindung, der zwischen der in Fig. 2 gezeigten ersten Schiene 6 und der zweiten Schiene 7 verschiebbar geführt ist und der zur Übertragung der Last der Schublade 3a, 3b vorgesehen ist. Der Laufwagen 8 umfasst einen Laufwagenkäfig 9 mit wenigstens zwei voneinander beabstandeten Lagergruppen 9a und 9b, die durch einen Steg 9c miteinander verbunden sind. Die Länge des Steges 9c kann je nach Länge der Schienen 6 und 7 variieren, d.h. lange Schienen 6 und 7 benötigen längere Laufwagen 8 bzw. Stege 9c, für kurze Schienen 6 und 7 sind kürzere Laufwagen 8 bzw. Stege 9c vorgesehen. Die Lagergruppen 9a und 9b sind sowohl in der Schließstellung der zweiten Schiene 7 als auch in deren Offenstellung mit der ersten Schiene 6 ständig in Kontakt. Hierfür weisen die Lagergruppen 9a und 9b mehrere lastübertragende Elemente 10 mit horizontalen Drehachsen als auch mehrere lastübertragende Elemente 10a auf, deren Drehachsen zumindest teilweise von der Horizontalen abweichen und vorzugsweise vertikal stehen. Die Neigung der Drehachsen der lastübertragenden Elemente 10a hängt von der Ausbildung bzw. Winkelstellung des in Fig. 2 dargestellten Laufsteges 6a der ersten Schiene 6 ab. Der Laufwagen 8 weist zudem eine gemäß dem Stand der Technik bekannte Steuemocke 11 auf, die zur Korrektur von sogenannten Laufwagenfehlern vorgesehen ist, die durch den Schlupf des Laufwagens 8 zwischen den Schienen eines wenigstens dreiteiligen Schienensystems hervorgerufen werden. Auf die nähere Funktion und Ausbildung der Steuemocke 11 wird im Rahmen der gegenständlichen Erfindung nicht näher Bezug genommen. Erfindungswesentlich ist, dass der Laufwagen 8 stirnseitig einen in dessen axialer Richtung und in Ausziehrichtung der Schienen 6, 7 weisenden Ausleger 15 umfasst, der an seinem freien Ende vorzugsweise drei zusätzliche lastübertragende Elemente 12 mit horizontalen Drehachsen trägt. Diese zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 stützen sich im Schließzustand der Schienen 6, 7 an der vorzugsweise korpusseitigen ersten Schiene 6 ab und werden im Schließzustand als vorderste lastübertragende Elemente 12 des Laufwagens 8 stärker als die übrigen lastübertragenden Elemente 10 des eigentlichen Laufwagenkäfigs 9 belastet, wodurch eine vorzeitige Abplattung der lastübertragenden Elemente 10 der beiden Lagergruppen 9a, 9b verhindert wird. Die zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 hingegen sind beim Ausziehen der vorzugsweise ladenseitigen zweiten Schiene 7 über das Ende der ersten Schiene 6 fahrbar, sodass die zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 in einer Offenstellung der Schienen 6, 7 nicht mehr an der ersten Schiene 6 anliegen.Fig. 3 shows an embodiment of a carriage 8 according to the aspect of the invention, which is slidably guided between the first rail 6 shown in Fig. 2 and the second rail 7 and which is provided for transmitting the load of the drawer 3a, 3b. The carriage 8 comprises a carriage cage 9 with at least two from each other spaced bearing groups 9a and 9b, which are interconnected by a web 9c. The length of the web 9c may vary depending on the length of the rails 6 and 7, ie long rails 6 and 7 require longer carriage 8 or webs 9c, for short rails 6 and 7 shorter carriage 8 and webs 9c are provided. The bearing groups 9a and 9b are constantly in contact both with the first rail 6 in the closed position of the second rail 7 and in its open position. For this purpose, the bearing groups 9a and 9b have a plurality of load-transmitting elements 10 with horizontal axes of rotation as well as a plurality of load-transmitting elements 10a whose axes of rotation at least partially deviate from the horizontal and are preferably vertical. The inclination of the axes of rotation of the load-transferring elements 10a depends on the formation or angular position of the catwalk 6a of the first rail 6 shown in FIG. The carriage 8 also has a prior art known control cam 11, which is provided for the correction of so-called carriage errors, which are caused by the slippage of the carriage 8 between the rails of an at least three-part rail system. On the closer function and design of the control cam 11 is not taken in the context of the present invention reference. Is essential to the invention that the carriage 8 frontally in the axial direction and in the direction of withdrawal of the rails 6, 7 pointing arm 15 which carries at its free end preferably three additional load-transmitting elements 12 with horizontal axes of rotation. These additional load-transferring elements 12 of the arm 15 are based in the closed state of the rails 6, 7 on the preferably body side first rail 6 and are loaded in the closed state as the foremost load-transferring elements 12 of the carriage 8 more than the other load-transferring elements 10 of the actual carriage cage 9, whereby premature flattening of the load-transmitting elements 10 of the two bearing groups 9a, 9b is prevented. The additional load-transmitting elements 12 of the boom 15, however, are mobile when pulling the preferably loading side second rail 7 over the end of the first rail 6, so that the additional load-transmitting elements 12 of the boom 15 in an open position of the rails 6, 7 no longer on the first rail 6 abut.

In der gezeigten Schließstellung der Schienen 6, 7 stützen sich die zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 am horizontalen Abschnitt des Laufsteges 6a der korpusseitigen ersten Schiene 6 ab. Der Laufsteg 6a wird von den lastübertragenden Elementen 10 der beiden Lagergruppen 9a und 9b auf dessen Oberseite und dessen Unterseite ständig kontaktiert.4a-4c show the foremost region of the pull-out guide 4 located in the closed position in different views. 4 a shows a plan view of the closed pull-out guide 4 with the first rail 6 to be fastened to the furniture body 2 (FIG. 1) and the second rail 7 to be fastened to the drawer 3 a, 3 b (FIG. 1). 4b shows a vertical section of the pull-out guide 4 along the plane II of FIG. 4a. Evident is the movable between the rails 6 and 7 carriage 8 (located within the rectangular section) with its spaced bearing groups 9a and 9b and its boom 15, at the distal end of the additional load-transmitting elements 12 are rotatably arranged. In the illustrated closed position of the rails 6, 7, the additional load-transmitting elements 12 of the arm 15 are supported on the horizontal portion of the catwalk 6a of the body-side first rail 6. The catwalk 6a is constantly contacted by the load-transferring elements 10 of the two storage groups 9a and 9b on its upper side and its underside.

Fig. 4c zeigt das in Fig. 4b eingezeichnete rechteckförmige Detail im vergrößerten Maßstab. Die horizontalen, lastübertragenden Elemente 10 der beiden Lagergruppen 9a und 9b umgreifen den horizontalen Laufsteg 6a der korpusseitigen ersten Schiene 6. Die zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 stützen sich im gezeigten Schließzustand der Schienen 6, 7 an der Oberseite des horizontalen Laufsteges 6a ab und dienen als zusätzliche Abstützrollen.FIG. 4c shows the rectangular detail drawn in FIG. 4b on an enlarged scale.

Fig. 5c zeigt das in Fig. 5b eingezeichnete rechteckförmige Detail in einem vergrößerten Maßstab, also eine vergrößerte geschnittene Seitenansicht der Ausziehführung 4. Zu erkennen ist, dass sich die zusätzlichen lastübertragenden Elemente 12 des Auslegers 15 nicht mehr mit der korpusseitigen ersten Schiene 6 bzw. deren Laufsteg 6a in Kontakt stehen, sondern beim Ausziehvorgang über das Ende des Laufsteges 6a hinaus gefahren wurden. Die lastübertragenden Elemente 10 der beiden Lagergruppen 9a und 9b kontaktieren weiterhin zu beiden Seiten des Laufsteges 6a die erste Schiene 6. Die erste Schiene 6 bzw. deren Laufsteg 6a weist - in Ausziehrichtung der zweiten Schiene 7 - im vorderen Bereich eine schematisch dargestellte Schrägfläche 13 auf. Diese Schrägfläche 13 dient dazu, die zusätz- liehen lastübertragenden Elemente 12 des Auslegers 15 beim Wiedereinschieben der zwei- ten Schiene 7 leichtgängig auf die Oberseite des Laufsteges 6a zu heben. Die Schrägfläche 13 ist in der gezeigten Figur als Abwinklung des Laufsteges 6a ausgebildet, es kann aber auch eine Neigung des Laufsteges 6a sowie eine separat angeordnete oder ausgebildete Auflaufschräge für die zusätzlichen lastübertragenden Elemente 12 vorgesehen werden.Fig. 5c shows the drawn in Fig. 5b rectangular detail on an enlarged scale, so an enlarged sectional side view of the pull-4. It can be seen that the additional load-transmitting elements 12 of the boom 15 is no longer with the body side first rail 6 and whose catwalk 6a are in contact, but were driven during the extraction process over the end of the catwalk 6a addition. The load-transferring elements 10 of the two storage groups 9a and 9b continue to contact the first rail 6 on both sides of the catwalk 6a. The first rail 6 or its catwalk 6a has - in the pull-out direction of the second rail 7 - a schematically illustrated inclined surface 13 in the front region , This oblique surface 13 serves the additional borrowed load-transferring elements 12 of the boom 15 when reinserting the two th rail 7 to lift easily on the top of the catwalk 6a. The inclined surface 13 is formed in the figure shown as a bend of the catwalk 6a, but it can also be an inclination of the catwalk 6a and a separately arranged or trained run-on slope for the additional load-transmitting elements 12 are provided.
