- Object of the present invention is therefore to provide a furniture pullout guide, which eliminates the above-mentioned disadvantages and in the total less lubricant must be used to achieve adequate lubrication of the pullout guide.
- the cage has a plurality of lubricant chambers for storing a lubricant.
- the lubricant chambers guide vanes with a scraper edge aligned transversely to the direction of movement of the pullout guide and protruding from the surface of the cage at least one of the rails.
- the guide blades protrude on both sides out of the surface of the cage. This makes it possible Apply the excess lubricant of the track of a rail on the opposite track of the second rail.
- a plurality of parallel-extending lubricant chambers are arranged transversely to the longitudinal direction of the cage in the longitudinal direction of the cage.
- the cage has a smaller wall thickness than in the remaining regions of the cage. This makes it possible that when the movable rail stop at an end point of the cage is preferably slightly deformed in this area of the smaller wall thickness, bringing the lubricant located in the lubricant chambers in contact with the raceways.
- one of the rails in the vicinity of a rail end at least one end stop, which is adapted to engage in at least one curved guide groove on an end face of the cage.
- the excess of non-lubricating film lubricant displaced by the rolling elements during a relative movement of the first rail to the second rail will accumulate in the lubricant chambers and subsequent relative movement of the rails of the lubricant accumulated in the lubricant chambers will rebuild a lubricating film on the raceways serve the rails. This ensures that despite the use of a smaller amount of lubricant this is stored and distributed efficiently in the pullout guide.
- a furniture drawer slide 1 comprises, as in FIG. 1 shown, a guide rail 2, which is mounted on a wall of a furniture body or a dishwasher or the like.
- a running rail 3 is held movable.
- a cage 4 is provided, on which a plurality of rolling elements 5, preferably in the form of balls or cylinders, are guided. These rolling elements 5 are arranged in recesses 7 in the walls of the cage 4.
- the cage 4 preferably surrounds the guide rail 2 from three sides and is formed to one side with a gap 10 through which the suspension of the first rail 2 engages.
- open lubricant chambers 8 for receiving and storing a lubricant 12 are provided in the walls of the cage 4 to the inside and outside of the chamber walls. Through this open design of the lubricant chambers 8, an exchange of lubricant 12 between the rails 2 and 3 is facilitated.
- the lubricant 12 is preferably a pasty lubricant such as a grease, which is suitable to slowly emerge from the lubricant chambers 8.
- the lubricant chambers 8 are arranged along a line extending parallel to the longitudinal axis of the cage or of the travel path of the rail 3 between the recesses 7 arranged in the same line, in which the rolling elements 5 are arranged.

Abstract
Description
Die vorliegende Erfindung betrifft eine Möbelauszugsführung gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Verteilung eines Schmierstoffes an wälzgelagerten Möbelauszugsführungen gemäß dem Oberbegriff des Anspruchs 11.The present invention relates to a furniture drawer slide according to the preamble of claim 1 and a method for distributing a lubricant to roller-mounted furniture drawer slides according to the preamble of
Eine möbelauszugsführung gemäß dem Oberbegriff des Anspruchs 1 ist aus
Bei den aus dem Stand der Technik bekannten und derzeit eingesetzten Möbelauszugsführungen wird ein eingebrachter Schmierstoff von den Wälzkörpern auf die Laufbahnen der Auszugsschienen verteilt und der überschüssige Anteil des Schmierstoffes von den Wälzkörpern verdrängt. Je nach Aufbau des Schmierstoffes verteilt sich der überschüssige Anteil unkontrolliert und wird somit nur zu einem geringen Anteil nutzbringend eingesetzt. Dies führt dazu, dass entweder die Schmierung vorzeitig versagt oder aber, dass eine größere Menge, mehr als notwendig, an Schmierstoff in die Auszugsführungen eingebracht wird. Ein solches Übermaß an Schmierstoff in den Auszugsführungen kann jedoch die Anlauf- und Laufeigenschaften negativ beeinflussen. Außerdem kann sich in dem verdrängten Schmierstoff, welcher sich ungenutzt auf den Laufbahnen der Schienen befindet, Schmutz ansammeln, so dass die Laufeigenschaften der Auszugsführung dadurch zusätzlich verschlechtert werden. Von Nachteil ist außerdem, dass der überschüssige Schmierstoff mit der Zeit aus den Auszugsführungen auslaufen kann, was zu Einschränkungen der Einsetzbarkeit eines solchen Systems insbesondere bei hohen Hygieneanforderungen führen kann.In the known from the prior art and currently used furniture drawer guides an introduced lubricant is distributed by the rolling elements on the tracks of the pull-out rails and displaced the excess portion of the lubricant from the rolling elements. Depending on the structure of the lubricant, the excess portion is distributed uncontrollably and is thus used profitably only to a small extent. As a result, either the lubrication fails prematurely or else a greater amount, more than necessary, of lubricant is introduced into the pullout guides. However, such an excess of lubricant in the drawer guides can adversely affect the start-up and running properties. In addition, in the displaced lubricant, which is unused on the tracks of the rails, dirt accumulate, so that the running properties of the pullout guide are thereby additionally deteriorated. Another disadvantage is that the excess lubricant can leak over time from the pullout guides, resulting in Restrictions on the applicability of such a system can lead in particular to high hygiene requirements.
Aufgabe der vorliegenden Erfindung ist es daher, eine Möbelauszugsführung zu schaffen, welche die oben genannten Nachteile beseitigt und bei der insgesamt weniger Schmierstoff eingesetzt werden muss, um eine ausreichende Schmierung der Auszugsführung zu erreichen.Object of the present invention is therefore to provide a furniture pullout guide, which eliminates the above-mentioned disadvantages and in the total less lubricant must be used to achieve adequate lubrication of the pullout guide.
Diese Aufgabe wird durch eine Möbelauszugsführung mit den Merkmalen des Anspruchs 1 und durch ein Verfahren zur Verteilung eines Schmierstoffes an wälzgelagerten Möbelauszugsführungen mit den Merkmalen des Anspruchs 11 gelöst.This object is achieved by a furniture pullout guide with the features of claim 1 and by a method for distributing a lubricant to roller-mounted furniture pullout guides with the features of
Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.Advantageous developments are the subject of the dependent claims.
Erfindungsgemäß weist der Käfig mehrere Schmierstoffkammern zur Lagerung eines Schmierstoffes auf. Dadurch ist ermöglicht, dass der in die Möbelauszugsführung eingebrachte Schmierstoff sich an definierten Orten in der Möbelauszugsführung sammeln kann und sich von dort aus auch wieder auf den Laufbahnen der Möbelauszugsführung verteilen kann. Außerdem ermöglicht dies einen geringeren Einsatz von Schmierstoff, was sich sowohl bei der Montage als auch im laufenden Betrieb kostensenkend auswirkt.According to the invention, the cage has a plurality of lubricant chambers for storing a lubricant. This makes it possible that the introduced into the furniture drawer guide lubricant can collect at defined locations in the furniture drawer guide and can distribute from there again on the tracks of the furniture drawer slide. In addition, this allows a lower use of lubricant, which has a cost-reducing effect both during assembly and during operation.
Gemäß einer Ausgestaltung der Erfindung weisen die Schmierstoffkammern Leitschaufeln mit einer quer zur Verfahrrichtung der Auszugsführung ausgerichteten und aus der Oberfläche des Käfigs zumindestens einer der Schienen hervorstehenden Abstreifkante auf. Durch diese Leitschaufeln ist ermöglicht, dass der verdrängte Schmierstoff zum einen in den Schmierstoffkammern gesammelt wird und zum anderen der zu schmierenden Schmierstelle wieder zugeführt wird. Ein weiterer Vorteil ist, dass durch das stetige Wiederzuführen des verdrängten Schmierstoffes dieser durchgewalkt wird und damit länger seine Schmiereigenschaften beibehält.According to one embodiment of the invention, the lubricant chambers guide vanes with a scraper edge aligned transversely to the direction of movement of the pullout guide and protruding from the surface of the cage at least one of the rails. Through this guide vanes is possible that the displaced lubricant is collected on the one hand in the lubricant chambers and on the other hand, the lubricating point to be lubricated is fed again. Another advantage is that the continuous reintroduction of the displaced lubricant, this is durchgewalkt and thus longer maintains its lubricating properties.
Gemäß einer weiteren Ausgestaltung der Erfindung stehen die Leitschaufeln zu beiden Seiten hin aus der Oberfläche des Käfigs hervor. Dadurch ist es ermöglicht, den überschüssigen Schmierstoff der Laufbahn einer Schiene auf der gegenüberliegenden Laufbahn der zweiten Schiene aufzubringen.According to a further embodiment of the invention, the guide blades protrude on both sides out of the surface of the cage. This makes it possible Apply the excess lubricant of the track of a rail on the opposite track of the second rail.
Gemäß einer weiteren Ausgestaltung der Erfindung sind quer zur Längsrichtung des Käfigs mehrere in Längsrichtung des Käfigs spaltenförmige parallel verlaufende Schmierstoffkammern angeordnet. Im Bereich dieser spaltenförmigen parallel verlaufenden Schmierstoffkammern weist der Käfig in einer Ausführungsform eine geringere Wanddicke auf als in den übrigen Bereichen des Käfigs. Dadurch ist ermöglicht, dass beim Anschlag der verfahrbaren Schiene an einem Endpunkt der Käfig sich bevorzugt in diesem Bereich der geringeren Wanddicke leicht verformt und dabei den in den Schmierstoffkammern befindlichen Schmierstoff in Kontakt mit den Laufbahnen bringt.According to a further embodiment of the invention, a plurality of parallel-extending lubricant chambers are arranged transversely to the longitudinal direction of the cage in the longitudinal direction of the cage. In the region of these column-shaped, parallel lubricant chambers, in one embodiment the cage has a smaller wall thickness than in the remaining regions of the cage. This makes it possible that when the movable rail stop at an end point of the cage is preferably slightly deformed in this area of the smaller wall thickness, bringing the lubricant located in the lubricant chambers in contact with the raceways.
Gemäß einer weiteren Ausgestaltung der Erfindung weist eine der Schienen in der Nähe eines Schienenendes mindestens einen Endanschlag auf, der geeignet ist, in mindestens eine gekrümmt ausgebildete Führungsnut an einer Stirnseite des Käfigs einzugreifen. Dadurch ist ermöglicht, dass beim Anschlag der beweglichen Schiene an einem Endpunkt der Käfig quer zu seiner Verfahrrichtung um einen Winkel α gekippt wird und dabei für eine Verteilung des in den Schmierstoffkammern sowie neben den Laufbahnen vorhandenen Schmierstoffes auf den Laufbahnen der Schienen sorgt.According to a further embodiment of the invention, one of the rails in the vicinity of a rail end at least one end stop, which is adapted to engage in at least one curved guide groove on an end face of the cage. This makes it possible that the stop of the movable rail at an end point of the cage is tilted transversely to its direction of travel by an angle α and thereby ensures a distribution of existing in the lubricant chambers and adjacent to the tracks lubricant on the tracks of the rails.
Bei dem erfindungsgemäßen Verfahren wird der von den Wälzkörpern während einer Relativbewegung der ersten Schiene zur zweiten Schiene verdrängte überschüssige, nicht einen Schmierfilm bildende Schmierstoff sich in den Schmierstoffkammern ansammeln und bei darauffolgenden Relativbewegungen der Schienen der in den Schmierstoffkammern angesammelte Schmierstoff dem Neuaufbau eines Schmierfilms auf den Laufbahnen der Schienen dienen. Dadurch wird erreicht, dass trotz des Einsatzes einer geringeren Schmierstoffmenge dieser effizient in der Auszugsführung gelagert und verteilt wird.In the method according to the invention, the excess of non-lubricating film lubricant displaced by the rolling elements during a relative movement of the first rail to the second rail will accumulate in the lubricant chambers and subsequent relative movement of the rails of the lubricant accumulated in the lubricant chambers will rebuild a lubricating film on the raceways serve the rails. This ensures that despite the use of a smaller amount of lubricant this is stored and distributed efficiently in the pullout guide.
Zur Erzielung eines Voll- oder Überauszuges kann zwischen der Führungsschiene und der Laufschiene mindestens eine auszugsverlängernde Mittelschiene angeordnet sein.To achieve a full or over excerpt can be arranged between the guide rail and the running rail at least one aussverlängernde middle rail.

Der Schmierstoff 12 ist dabei bevorzugt ein pastöser Schmierstoff wie beispielsweise ein Schmierfett, welches geeignet ist, langsam aus den Schmierstoffkammern 8 auszutreten.The
In einer bevorzugten Ausgestaltung sind die Schmierstoffkammern 8 entlang einer parallel zur Längsachse des Käfigs verlaufenden Linie beziehungsweise des Verfahrwegs der Schiene 3 zwischen den auf der gleichen Linie angeordneten Aussparungen 7, in denen die Wälzkörper 5 angeordnet sind, angeordnet. In jeder der Schmierstoffkammern 8 ist, wie in den
Die Abstreiferkanten 9 der Leitschaufeln 6 sind dabei bevorzugt trapezartig ausgebildet. Dadurch wird erreicht, dass während des Verfahrens des Käfigs relativ zu den Schienen 2, 3 mittig auf einer Laufbahn 13, 14 der Schienen 2, 3 eine Schmierstoffraupe ausgebildet wird. Der nicht zur Ausbildung der Schmierstoffraupe auf der Laufbahn 13, 14 verbleibende Schmierstoff wird durch die Leitschaufel 6 zurückgehalten und in der in Verfahrrichtung vor der Leitschaufel 6 befindlichen Schmierstoffkammer 8 abgelagert.The scraper edges 9 of the
Die Schmierstoffraupe wird anschließend von einem der hinter den Leitschaufeln 6 in dem Käfig 4 angeordneten Wälzkörper 5 überrollt und zu einen Schmierstofffilm 11 ausgebreitet, wie in den

Gemäß einer weiteren bevorzugten Ausführungsform der Möbelauszugsführung 1 sind die Aussparungen 22, in denen die Wälzkörper 5 angeordnet sind, auf mehreren in Längsrichtung des Käfigs 19 verlaufenden Bahnen parallel zueinander angeordnet und die Schmierstoffkammern 21 sind auf einer parallel verlaufenden Bahn zwischen diesen mit den Aussparungen 22 für die Wälzkörper 5 versehenen Bahnen angeordnet. Dadurch kann der von den Wälzkörpern 5 zur Seite gedrängte Schmierstoff 12 von den dort angeordneten Schmierstoffkammern 21 während des Verfahrens des Käfigs 12 über die Schienen 2, 3 aufgenommen werden.According to a further preferred embodiment of the furniture drawer guide 1, the
Besonders bevorzugt weist eine der Schienen 2, 3, in der Nähe eines Schienenendes mindestens einen Endanschlag 23 auf, welcher geeignet ist, in mindestens eine gekrümmt ausgebildete Führungsnut 20 an einer Stirnseite des Käfigs 19 einzugreifen. Dadurch wird, wie anhand der
Bei dem erfindungsgemäßen Verfahren zur Verteilung des Schmierstoffs 12 wird der Schmierstoff 12 von den Wälzkörpern 5 auf den Laufbahnen 13, 14 der Schienen 2, 3 während einer Relativbewegung der ersten Schienen 2 zur zweiten Schiene 3 verteilt. Dies geschieht dadurch, dass der von den Wälzkörpern 5 während einer Relativbewegung der ersten Schiene 2 zur zweiten Schiene 3 verdrängte überschüssige, nicht einen Schmierfilm 11 bildende Schmierstoff 12 sich in den Schmierstoffkammern 8, 15, 21 ansammelt und bei folgenden Relativbewegungen der Schienen 2, 3, zueinander dieser in den Schmierstoffkammern 8, 15, 21 angesammelte Schmierstoff 12 dem Neuaufbau eines Schmierfilms 11 dient.In the method according to the invention for distributing the
