Abstract

Telescopic rail system comprising C-shaped outer rails (12), C-shaped middle rails (13) and I-shaped inner rails (14), as those mounted particularly on vehicle doors. Heretofore, those systems where provided with series of steel bearing balls in races. The invention proposes to arrange balls in contact between them, without races, and to use alternatingly steel and plastic balls. In the preferred form of execution, 2-3 steel balls will be used at each end of the rails.

Es sind Kugelschienensysteme entsprechend Fig. 1 bekannt ge¬ worden, bei welchen die aus Stahl bestehenden Kugeln in Blechkäfigen so gehalten werden, daß alle Kugeln gleichen Abstand voneinander haben, sich aber gegenseitig nicht be¬ rühren. Der Auszug dieser Systeme ist durch aufwendige An¬ schläge zu begrenzen, da die Kugelkäfige oder Kugelkörbe nicht auf Stauchung beansprucht werden dürfen. Außerdem stört vielfach das Laufgeräusch. Fig. 1 zeigt im Querschnitt ein seit Jahren bekanntes Kugel¬ schienensystem, wie es vorwiegend bei Fahrzeugschwenkschie¬ betüren eingesetzt wird. Das System besteht aus einem äuße¬ ren C-förmigen Träger 1 , einem mittleren C-förmigen Träger 2, einem inneren I-förmigen Träger 3, den Kugelreihen 4, 5, 6, 7 und den C-förmigen Kugelkäfigen 8, 9.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Ku¬ gelschienensysteme zu vereinfachen, die Tragfähigkeit zu er¬ höhen, ihren Platzbedarf zu verringern und die Geräuschent¬ wicklung zu dämpfen.The invention is based on the object of simplifying the known ball rail systems, increasing the load capacity, reducing their space requirement and damping noise.
Diese Aufgabe wird dadurch gelöst, daß die Lagerkugeln ohne Kugelkäfige verlegt sind und abwechselnd aus Stahl und Kunst¬ stoff bestehen.This object is achieved in that the bearing balls are laid without ball cages and consist alternately of steel and plastic.
Beschreibung der ZeichnungDescription of the drawing
Fig. 2 zeigt einen Querschnitt durch das neuartige System. Die äußere C-Schiene ist mit 12, die mittlere mit 13 und die innere I-Schiene mit 14 bezeichnet. Dazwischen liegen die Kugelreihen 15, 16, 17, 18.Fig. 2 shows a cross section through the novel system. The outer C-rail is designated 12, the middle 13 and the inner I-rail 14. In between are the rows of balls 15, 16, 17, 18.
In Fig. 3 ist das System im ausgezogenen Zustand gezeichnet. Die Schienen 12 und 13 sind am rechten Ende durch Endstücke 19 und 20 verschlossen, so daß die Kugeln nicht herausfallen können. Die Schienen 13 und 14 tragen am linken Ende über¬ stehende Anschlagscheiben 21 und 22, die die Kugeln beim Ausziehen des Systems mitnehmen und vor sich herschieben, bis in der Endstellung alle Kugeln einer Reihe aufeinander¬ stoßen. Hervorstechendes Merkmal ist es nun, daß die Kugeln abwechselnd aus Stahl und Kunststoff bestehen, wobei an den Enden aus Festigkeitsgründen jeweils 1 - 3 Stahlkugeln vor¬ gesehen werden können. Die Stahlkugeln sind punktiert ge¬ zeichnet. Da beim Ausziehen des Systems abwechselnd Stahl- und Kunststoffkugeln aufeinanderstoßen, ist die Geräusch- entwicklung erheblich geringer als bei bekannten Anordnungen, Auch wirkt sich die geringe Reibung von Kunststoff auf Stahl beim Abrollen positiv aus. Ein weiterer Vorteil ist darin zu sehen, daß bei ausgezogenem System, also bei offener Tür und höchster mechanischer Belastung, die Kugeln dicht an dicht liegen und somit die Kräfte und Momente gut weiterleiten können. Man kommt also mit einer wesentlich kleineren Min- destüberdeckung aus als bisher. Anders gesagt, kann man das System ohne Gefährdung weiter ausziehen. Die Belastbarkeit wird noch dadurch erhöht, daß der vertikale Steg des mittle¬ ren Profils 13 bei gleichen Außenabmessungen viel stärker ausgebildet werden kann. Die geänderten Stärkenverhältnisse kann man ohne weiteres aus den maßstabgetreuen Fig. 1 und 2 ablesen. Gerade das am stärksten belastete mittlere Profil läßt sich somit entscheidend versteifen.In Fig. 3 the system is drawn in the extended state. The rails 12 and 13 are closed at the right end by end pieces 19 and 20 so that the balls cannot fall out. The rails 13 and 14 carry at the left end protruding stop disks 21 and 22 which take the balls with them when the system is pulled out and push them in front of them until all balls in a row collide in the end position. A salient feature is that the balls are made of steel and plastic alternately, with 1-3 steel balls being provided at the ends for reasons of strength. The steel balls are dotted. Since steel and plastic balls alternately collide when the system is pulled out, the noise is development significantly less than with known arrangements, the low friction of plastic on steel has a positive effect when rolling. Another advantage can be seen in the fact that when the system is pulled out, that is to say when the door is open and the mechanical load is high, the balls lie close together and can therefore transmit the forces and moments well. So you can get by with a much smaller minimum coverage than before. In other words, the system can be pulled out without endangering. The load capacity is further increased by the fact that the vertical web of the central profile 13 can be made much stronger with the same external dimensions. The changed strength ratios can be easily read from the true-to-scale FIGS. 1 and 2. The most heavily loaded middle profile can thus be decisively stiffened.
Beim Zusammenschieben des Systems gewinnen die Kugeln Ab¬ stand voneinander, wobei sich ihre Lage nach dem Prinzip der kleinsten Reibung bestimmt. Der Ort der Kugeln bei geschlos¬ sener Tür wandert im statistischen Mittel, so daß immer wie- der an anderen und neuen Punkten der Kugelrillen die Kräfte eingeleitet werden.When the system is pushed together, the balls gain spacing from one another, their position being determined according to the principle of minimum friction. The location of the balls when the door is closed moves on a statistical average, so that the forces are introduced again and again at other and new points of the ball grooves.
Bei dem bekannten System liegen die Kugeln infolge der Zwangsführung in den Käfigen bei geschlossener Tür immer an den gleichen Stellen auf, so daß die Kugelrillen infolge der Fahrerschütterungen ausgeschlagen werden können.In the known system, the balls are always in the same places due to the positive guidance in the cages when the door is closed, so that the ball grooves can be knocked out as a result of driver vibrations.
Das neuartige Teleskopschienensystem verbindet in vorteil¬ hafter Weise die hohe Tragfähigkeit von Stahlkugellagern mit dem leisen Lauf der an sich bekannten Kugellager mit Kunst¬ stoffkugeln.The novel telescopic rail system advantageously combines the high load-bearing capacity of steel ball bearings with the quiet running of the ball bearings known per se with plastic balls.
Bester Weg zur Ausführung der ErfindungBest way to carry out the invention
Der beste Weg zur Ausführung der Erfindung ist darin zu sehen, daß man alternierend Stahl- und Kunststoffkugeln ver¬ wendet und als Ausnahme von dieser Regel an den Enden je¬ weils einige Stahlkugeln vorsieht. Die C- und I-Profile kön- nen stranggepreßt oder gewalzt sein. Gewerbliche VerwertbarkeitThe best way to carry out the invention is to use steel and plastic balls alternately and, as an exception to this rule, to provide some steel balls at the ends. The C and I profiles can be extruded or rolled. Commercial usability
Die Erfindung soll vorwiegend bei Fahrzeugtüren oder Schie¬ betüren allgemein eingesetzt werden. Sie bietet aber auch Vorteile bei Möbeln, insbesondere bei Schubladen oder Aus- ziehplatten. The invention is intended to be used primarily for vehicle doors or sliding doors in general. But it also offers advantages for furniture, especially for drawers or pull-out shelves.
