Description

Die Erfindung betrifft eine Rollenführung für insbesondere schubladenartig herausfahrbare Behältnisse von Haushaltsgeräten, insbesondere Geschirrspülmaschinen.The invention relates to a roller guide for in particular drawer-like retractable containers of household appliances, especially dishwashers.

Um beispielsweise Geschirrkörbe aus dem Spülraum eines Geschirrspülers herausziehen zu können, sind Führungssysteme bekannt mit ersten Laufrollen, die wenigstens ein Paar gegenüberliegender Schienen in bezug auf den Spülraum führen, und zweiten Laufrollen, die den Geschirrkorb in bezug auf die Schienen führen. Dabei sind die ersten Laufrollen an gegenüberliegenden Längsseiten der Schienen und die zweiten Laufrollen in den Schienen angeordnet oder umgekehrt.For example, in order to be able to extract baskets from the dishwashing compartment of a dishwasher, guide systems are known having first rollers guiding at least a pair of opposing rails with respect to the washing compartment and second rollers guiding the dish rack with respect to the rails. The first rollers are arranged on opposite longitudinal sides of the rails and the second rollers in the rails or vice versa.

Eine bekannte Geschirrspülmaschine gemäß DE 29 92 915 U1 weist Rollenführungen mit Führungsschienen und darin laufenden Laufrollen auf, die im herausgefahrenen Zustand in schienengebundenen Kappen sitzen, die den laufrollengeführten Geschirrkorb wenigstens im ausgefahrenen Zustand stabil halten sollen, indem Vorsprünge dieser Kappen an den Seiten der Laufrollen spielfrei anliegen. Dies gelingt jedoch nur dann, wenn gegenüberliegende Laufrollen symmetrisch geführt sind. Ansonsten wird immer eine Laufrolle spielfrei und die andere spielbehaftet in der Kappe sitzen, so daß der durch die Laufrollen geführte Geschirrkorb auch im ausgefahrenen Zustand nicht stabil genug gehalten wird.A known dishwasher according DE 29 92 915 U1 has roller guides with guide rails and rollers running in it, sitting in the retracted state in rail-bound caps that should keep the roller table guided crockery stable at least in the extended state by rest projections of these caps on the sides of the rollers without play. However, this only succeeds if opposing rollers are guided symmetrically. Otherwise, always one Run roller clearance and the other game with a seat in the cap, so that the guided by the rollers dish rack is not held stable enough even in the extended state.

Der Erfindung liegt die Aufgabe zugrunde, die Stabilität des ausgefahrenen Behältnisses zu verbessern.The invention has for its object to improve the stability of the extended container.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 16 gelöst.According to the invention, this object is solved by the features of claims 1 and 16.

Die Rollenführung für insbesondere schubladenartig herausfahrbare Behältnisse von Haushaltsgeräten, insbesondere Geschirrspülmaschinen, besitzt eine Schiene, wenigstens eine in der Schiene laufende Laufrolle und einen am Ende der Schiene angeordneten ersten Einlauf zur wenigstens abschnittsweisen spielfreien Aufnahme einer Laufrollenachse. Im Gegensatz zur Aufnahme der Laufrolle selbst sichert die Aufnahme der Laufrollenachse Spielfreiheit auch bei unsymmetrischer Laufrollenführung.The roller guide for in particular drawer-like retractable containers of household appliances, especially dishwashers, has a rail, at least one roller running in the rail and arranged at the end of the rail first inlet for at least partially play-free recording a roller axis. In contrast to the inclusion of the roller itself, the recording of the roller axle backlash secures even with asymmetrical roller guide.

Der insbesondere als Schlitz vorgesehene erste Einlauf ist in bezug auf die Laufrollenachse federnd und/oder klemmend ausgebildet, könnte aber auch exakt auf den Durchmesser der Laufrollenachse abgestimmt sein. Er weist eine quer zur Laufrollenachse wirkende Einengung auf, die insbesondere zum Schienenende hin kontinuierlich zunimmt, parallel zur Laufrichtung der Laufrolle verläuft oder diskret ist. Dabei kann die Einengung gegenüberliegend oder einseitig sein.The designated in particular as a slot first inlet is resilient and / or clamped with respect to the roller axis, but could also be matched exactly to the diameter of the roller axis. It has a constriction acting transversely to the roller axis, which continuously increases in particular towards the rail end, runs parallel to the running direction of the roller or is discrete. The restriction may be opposite or one-sided.

Dem ersten Einlauf zur zumindest abschnittsweisen spielfreien Aufnahme der Laufrollenachse ist vorzugsweise ein zweiter Einlauf zur zumindest zeitweisen spielfreien Aufnahme der Laufrolle zugeordnet.The first inlet for at least partially play-free recording of the roller axis is preferably a second inlet for at least temporarily play-free recording of the roller assigned.

Der insbesondere als Erhebung bzw. Vorsprung vorgesehene zweite Einlauf ist in bezug auf die Laufrolle federnd und/oder klemmend ausgebildet. Er weist eine längs der Laufrollenachse auf die Laufrolle wirkende Einengung auf, die insbesondere zum Schienenende hin kontinuierlich zunimmt, parallel zur Laufrichtung der Laufrolle verläuft oder diskret ist. Eine einseitige Ausbildung der Einengung ist hier bevorzugt.The particular envisaged as a survey or projection second inlet is resilient and / or clamped with respect to the roller. It has a restriction acting along the roller axis on the roller, which continuously increases in particular towards the rail end, runs parallel to the running direction of the roller or is discrete. A one-sided training of constriction is preferred here.

Der erste und/oder der zweite Einlauf können in einer am Ende der Schiene angeordneten, insbesondere auf die Schiene aufgesteckten Kappe ausgebildet sein.The first and / or the second inlet can be formed in a cap which is arranged at the end of the rail and is attached in particular to the rail.

Eine Rollenführung weist insbesondere in Schienenrichtung verteilte Laufrollen auf, die am Behältnis oder am Haushaltsgerät angeordnet sein können, wobei die bedienerzugewandte vordere Laufrolle bzw. deren Achse mit dem ersten und/oder zweiten Einlauf zusammenwirkt.A roller guide has in particular in the rail direction distributed rollers that can be arranged on the container or the household appliance, wherein the operator-facing front roller or its axis cooperates with the first and / or second inlet.

Ein Haushaltsgerät, insbesondere Geschirrspülmaschine, besitzt vorzugsweise wenigstens ein Paar gegenüberliegender Rollenführungen der beschriebenen Art.A domestic appliance, in particular a dishwasher, preferably has at least one pair of opposing roller guides of the type described.

Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert. In den zugehörigen Zeichnungen zeigen:

  • Fig. 1 eine bekannte Endkappe,
  • Fig. 2 eine in der bekannten Endkappe in einer ersten Querposition aufgenommene Laufrolle,
  • Fig. 3 eine in der bekannten Endkappe in einer zweiten Querposition aufgenommene Laufrolle.
  • Fig. 4 eine erfindungsgemäße Endkappe,
  • Fig. 5 eine in der erfindungsgemäßen Endkappe in einer ersten Querposition aufgenommene Laufrolle und
  • Fig. 6 eine in der erfindungsgemäßen Endkappe in einer zweiten Querposition aufgenommene Laufrolle.
The invention will be explained in more detail with reference to an embodiment. In the accompanying drawings show:
  • 1 shows a known end cap,
  • 2 a recorded in the known end cap in a first transverse position roller,
  • Fig. 3 is a recorded in the known end cap in a second transverse position roller.
  • 4 shows an end cap according to the invention,
  • Fig. 5 is a recorded in the end cap according to the invention in a first transverse position roller and
  • Fig. 6 is a recorded in the end cap according to the invention in a second transverse position roller.

Eine bekannte Endkappe 2 gemäß Fig. 1-3 besitzt ebenso wie die Führungsschiene 4 einen C-förmigen Querschnitt mit zwei gegenüberliegenden spiegelbildlichen Wölbungen 8, 10, die auf einer Seite durch eine geschlossene Wand 12 verbunden sind und auf der gegenüberliegenden anderen Seite eine Öffnung 14 freigeben.A well-known end cap 2 according to FIGS. 1-3 has, just like the guide rail 4, a C-shaped cross section with two opposite mirror-image bulges 8, 10 which are connected on one side by a closed wall 12 and on the opposite other side an opening 14 release.

Sie ist an ihrem einen Ende 16 offen, um auf ein Ende 18 der Führungsschiene aufgesteckt zu werden, und an ihrem anderen Ende 20 geschlossen, um für eine in der Führungsschiene 4 laufende Laufrolle (Laufrad) 22 einen Anschlag zu bilden.It is open at its one end 16 to be fitted onto one end 18 of the guide rail, and closed at its other end 20 to form a stop for a roller (impeller) 22 running in the guide rail 4.

Die Wand 12 ist gegenüber den Wölbungen 8, 10 innen etwas zurückgesetzt und dadurch dünner als diese. Auf ihrer Innenseite 24 erheben sich zwei in Längsrichtung parallel zueinander verlaufende Rippen (Vorsprünge) 26, die in einem vom offenen Ende 16 ausgehenden ersten Abschnitt 28 schräg ansteigen und in einem anschließenden zweiten Abschnitt 30 auf gleichbleibendem Niveau verlaufen.The wall 12 is slightly set back relative to the bulges 8, 10 and thus thinner than this. On its inner side 24 rise two longitudinally mutually parallel ribs (projections) 26 which rise obliquely in an outgoing from the open end 16 first portion 28 and extend in a subsequent second section 30 at a constant level.

Je nachdem, ob sich die Laufrolle 22 näher an der Öffnung 14 (Fig.3) oder näher an der Wand 12 (Fig. 2) der Endkappe 2 befindet, weist sie einen Abstand zu den Rippen 26 auf oder liegen diese stabilisierend an der Laufrolle 22 an.Depending on whether the roller 22 is closer to the opening 14 (Figure 3) or closer to the wall 12 (Fig. 2) of the end cap 2, it has a distance from the ribs 26 or are these stabilizing on the roller 22 on.

Zur Verbesserung der Stabilität einer in einer Endlage befindlichen Laufrolle 22 weist eine erfindungsgemäße Endkappe 32 gemäß Fig. 4-6 in der Wand 12 zusätzlich zu den Rippen 26 einen Schlitz 34 auf, der sich vom offenen Ende 16 aus in Richtung des geschlossenen Endes 20 erstreckt, wobei er sich in einem (ersten) Abschnitt zunehmend verengen kann, bevor er in einem anschließenden (zweiten) Abschnitt eine konstante lichte Weite aufweist. Obwohl prinzipiell beidseitig des Schlitzes 34 möglich, ergibt sich eine eventuelle Verengung vorzugsweise aus einer unteren Anlaufschräge des Schlitzes 34, während der obere Rand 42 parallel zur Längserstreckung der Führungsschiene 4 verläuft.To improve the stability of a roller 22 located in an end position, an end cap 32 according to the invention has 4-6 in the wall 12 in addition to the ribs 26, a slot 34 which extends from the open end 16 in the direction of the closed end 20, wherein it can increasingly narrow in a (first) section before moving in a subsequent (second) section has a constant clear width. Although in principle possible on both sides of the slot 34, a possible constriction preferably results from a lower starting bevel of the slot 34, while the upper edge 42 extends parallel to the longitudinal extension of the guide rail 4.

Insgesamt ist der Schlitz 34 so positioniert, daß die Achse 44 der Laufrolle 22 in den Schlitz 34 einfahren kann. Beim hier dargestellten C-förmigen Querschnitt von Endkappe 32 und Führungsschiene 4 befindet sich der Schlitz 34 etwa mittig zwischen den Wölbungen 8, 10 der Endkappe 32 und deren Rippen 26. Anders als die bekannten Endkappen 2, die mit der Öffnung 14 zur Achse 44 der Laufrolle 22 aufgesteckt sind, weist bei den erfindungsgemäßen Endkappen 32 die Wand 12 mit dem Schlitz 34 zur Laufrollenachse 44.Overall, the slot 34 is positioned so that the axle 44 of the roller 22 can retract into the slot 34. In the C-shaped cross-section of end cap 32 and guide rail 4 shown here, the slot 34 is located approximately centrally between the bulges 8, 10 of the end cap 32 and the ribs 26. Unlike the known end caps 2, with the opening 14 to the axis 44 of the Roller 22 are plugged, has in the inventive end caps 32, the wall 12 with the slot 34 to the roller axis 44th

In den Führungsschienen 4, die an nichtdargestellten gegenüberliegenden Wandungen eines Spülraumes eines Geschirrspülers fest oder nach vorn herausbewegbar angeordnet sein können, laufen jeweils wenigstens zwei voneinander beabstandete Laufrollen 22, deren Achsen 44 an einem wiederum nichtdargestellten Geschirrkorb angeordnet sind. Da der Abstand der Laufrollen 22 längs der Führungsschienen 4 deutlich geringer ist als deren Länge, läßt sich der Geschirrkorb in Bezug auf die Führungsschienen aus dem Spülraum herausziehen und in diesen hineinschieben.In the guide rails 4, which can be arranged to be moved outwards or downwards on non-illustrated opposite walls of a washing compartment of a dishwasher, run at least two spaced-apart rollers 22, the axes 44 are arranged on a again not shown dish rack. Since the distance between the rollers 22 along the guide rails 4 is significantly less than their length, the crockery basket can be pulled out with respect to the guide rails from the washing and push it into this.

Die Wirkungsweise ist folgende:The mode of action is the following:

Wird der Geschirrkorb oder ein anderes Behältnis eines Haushaltsgerätes aus dem Spülraum oder einem anderen Arbeitsraum herausgezogen, bewegen sich zuerst die Führungsschienen 4 in bezug auf den Spülraum und dann der Geschirrkorb in bezug auf die Führungsschienen 4, indem alle Laufrollen 22 in den Führungsschienen 4 abrollen, bis die vorderen Laufrollen 22 in die vorzugsweise aus Kunststoff bestehenden Endkappen 32 einfahren, wo ihr seitliches Spiel durch die seitlich vorspringenden Rippen 26 beschränkt wird. Da dieses Spiel auch vom Abstand der gegenüberliegenden Führungsschienen 4 und dem Abstand der gegenüberliegenden Laufrollen 22 abhängt, ist ein seitliches Klemmen der vorderen Laufrollen 22 nicht in jedem Fall gegeben.When the crockery basket or other container of a domestic appliance is withdrawn from the washing room or other work space, first the guide rails 4 move with respect to the washing room and then the crockery basket with respect to the guide rails 4 by rolling all the casters 22 in the guide rails 4, until the front rollers 22 retract into the preferably plastic end caps 32, where their lateral play is limited by the laterally projecting ribs 26. Since this game also depends on the distance between the opposite guide rails 4 and the distance of the opposite rollers 22, a lateral clamping of the front rollers 22 is not given in each case.

Dies wird jedoch dadurch ausgeglichen, daß mit dem Einlaufen der vorderen Laufrollen 22 in die Endkappen 32 gleichzeitig die Laufrollenachsen 44 in die Schlitze 34 einlaufen, in denen sie nach dem Passieren der sich eventuell verengenden (ersten) Abschnitte'in den (zweiten) Abschnitten achsnormal geklemmt werden.However, this is offset by the fact that with the running of the front rollers 22 in the end caps 32 at the same time the roller axles 44 run into the slots 34 in which they achsnormal after passing the possibly narrowing (first) sections'in the (second) sections be clamped.

Obwohl anhand einer spezifisch geschlitzten Endkappe für Führungsschienen einer Oberkorbführung eines Geschirrspülers dargestellt, umfaßt die Erfindung selbstverständlich auch andere Ausführungen. So ist es denkbar, kontinuierliche Verengungen der Schlitze durch diskrete Verengungen zu ersetzen, die beispielsweise einen Anlaufbereich von einem sich wieder erweiternden Bereich trennen, so daß sich der Schlitz schlüssellochartig darstellt. Auch sind neben anderen Querschnitten der Endkappen und/oder der Führungsschienen andere erste Einläufe vorgesehen, sofern eine spielfreie Achsaufnahme, beispielsweise eine federnde Achsklemmung möglich bleibt.Although illustrated with reference to a specifically slotted guide-rail end cap of an upper basket guide of a dishwasher, it will be understood that the invention includes other embodiments as well. Thus, it is conceivable to replace continuous narrowings of the slots by discrete constrictions which, for example, separate a start-up area from a re-expanding area, so that the slot is keyhole-shaped. Also, in addition to other cross sections of the end caps and / or the guide rails other first enemas provided that a backlash-free axle, for example, a resilient Achsklemmung remains possible.
