Description

Die Erfindung betrifft einen schienengeführt herausziehbaren Kühlgutträger nach dem Oberbegriff von Anspruch 1.The invention relates to a rail-guided refrigerated goods carrier according to the preamble of claim 1.

Kühlgutträger, insbesondere in Kältegeräten wie Gefrierschränken und Kühlschränken werden gerne mit Schienenauszügen ausgestattet, so dass sie zur leichten Erreichbarkeit und Entnahme von Kühlgut das sich auch im hinteren Bereich des Kühlgutträgers befinden kann, herausgezogen werden können. Hierfür werden wie in der DE 103 04 670 A1 beschrieben beispielsweise Teleskopschienen verwendet, um eine exakte Führung der Kühlgutträger zu gewährleisten, welche eine ruckfreie Bewegung des Kühlgutträgers ermöglicht. Es gibt aber auch Auszugsysteme, in denen am Kühlgutträger befestigte Rollen in einer einzigen Schiene des Auszugs laufen. Des weiteren werden Auszüge für Kühlgutträger verwendet, bei denen eine Rolle am Kühlgutträger und eine weitere an einem Führungsschienenteil angeordnet sind, wobei der Führungskanal für beide Rollen entweder durch die eine Führungsschiene oder durch ein Schienenpaar gebildet wird, wobei ein Festschienenelement und ein am Kühlgutträger befindliches Losschienenelement zusammenwirken. Allen hierbei erwähnten Schienenanordnungen für derartige Auszüge von Kühlgutträgern ist gemeinsam, dass Laufrollen in durch die Schienen gebildete Laufkanäle eingreifen, welche oftmals an den Kühlgutträgern angeordnet sind. Da es sich bei den Kühlgutträgern, insbesondere wenn sie als tiefere Behälter geformt sind, oftmals um tiefgezogene oder spitzgeformte Kunststoffteile handelt, müssen diese Laufräder nachträglich montiert werden, wobei sie gut am Kühlgutträger fixiert sein müssen, was insbesondere eine Verdrehsicherung beinhaltet und ihre Haltbarkeit und Leichtgängigkeit gewährleistet sein muss, ohne dass große Herstellungs- oder Montagekosten entstehen dürften. Herkömmliche Laufräder weisen im Allgemeinen Befestigungen auf, welche umständlich mittels Werkzeugen montierbar sind. Dies führt zu unnötig hohen Montagekosten.Refrigerated goods, especially in refrigerators such as freezers and refrigerators are often equipped with rail extensions so that they can be pulled out for easy access and removal of refrigerated goods that can also be located in the rear of the refrigerated goods. For this purpose, as in the DE 103 04 670 A1 described, for example, telescopic rails used to ensure an exact guidance of refrigerated goods, which allows a smooth movement of the refrigerated goods carrier. But there are also pull-out systems in which run on the refrigerated goods carrier rollers run in a single rail of the drawer. Furthermore, extracts are used for refrigerated goods, in which a roll on Kühlgutträger and another are arranged on a guide rail part, wherein the guide channel is formed for both roles either by a guide rail or by a pair of rails, wherein a fixed rail member and located on Kühlgutträger Losschienenelement interact. Allen mentioned rail arrangements for such extracts of refrigerated goods is common that rollers engage in formed by the rails run channels, which are often arranged on the refrigerated goods carriers. Since it is in the refrigerated goods, especially if they are shaped as a deeper container, often deep-drawn or pointed plastic parts, these wheels must be retrofitted, where they must be well fixed on refrigerated goods, which in particular includes a rotation and their durability and ease must be ensured without large manufacturing or assembly costs should arise. Conventional wheels generally have fasteners that are cumbersome to mount using tools. This leads to unnecessarily high installation costs.

Die WO 03/039323 A1 offenbart einen Rollenhalter für einen Geschirrspüler zur Aufnahhme von Geschirrkörben vorgesehen Schienenelementen. Der Rollenhalter umfasst einen Zentralkörper, der am Spülbehälter der Geschirrspülmaschine dauerhaft befestigt ist, und ein Rollenelement, das so auf dem Zentralkörper angeordnet und ausgebildet ist, dass es die Schienenelemente aufnimmt.The WO 03/039323 A1 discloses a roll holder for a dishwasher for receiving provided by baskets rail elements. The roll holder includes a center body permanently fixed to the washing compartment of the dishwasher, and a roller member disposed and formed on the center body so as to receive the rail elements.

EP 0 718 575 A1 offenbart ein Kältegerät mit wenigstens einem innerhalb seines wärmeisolierenden Gehäuses angeordneten, zu Lagerung von Lagergut dienenden Nutzraum, innerhalb welchem zumindest ein an seinen beiden Längsseiten an Laufrollen geführtes Ablagefach angeordnet ist, wobei die Laufrollen in an den Seitenwänden des wärmeisolierenden Gehäuses angeordneten Führungsschienen geführt sind, an deren vom Nutzraum abgewandten Außenseiten das Wärmeisolationsmaterial zumindest weitestgehend anliegend herangeführt ist. EP 0 718 575 A1 discloses a refrigerator with at least one disposed within its heat-insulating housing, serving for storage of storage space within which at least one guided on its two longitudinal sides of casters tray is arranged, wherein the rollers are guided in arranged on the side walls of the heat-insulating housing guide rails on whose outer surfaces facing away from the useful space, the heat insulation material is brought at least largely fitting.

Der Erfindung liegt die Aufgabe zugrunde, einen herausziehbaren Kühlgutträger mit einem Laufrad zu entwickeln, das einfach am Kühlgutträger montierbar und zugleich auf einfache Weise ortsfest fixiert ist.The invention has for its object to develop a pull-out refrigerated goods with an impeller that is easy to mount on refrigerated goods and at the same time fixed in a simple manner stationary.

Gelöst wird die Aufgabe gemäß der Erfindung durch einen herausziehbaren Kühlgutträger mit den Merkmalen des Anspruchs 1.The object is achieved according to the invention by a pull-out refrigerated goods with the features of claim 1.

Erfindungsgemäß weist das Laufrad im wesentlichen zwei Bestandteile auf, ein als Achsstummel dienendes Achselement und eine Rolle, die auf dem Achselement läuft und in die Schienen eingreift, wobei das Achselement Rastelemente aufweist, die einer Fixierung des Achsenelements an dem Kühlgutträger, einer daran angeordneten Schiene, oder an der Aussparung am Kühlgutträger durch die das Achselement durchtritt und/oder der Fixierung der Laufrolle auf dem Achselement dienen. Aufgrund der Rastelemente rastet das Achselement des Laufrades einfach in eine dafür vorgesehene Aussparung des Kühlgutträgers ein, sobald es durch diesen hindurchgeführt wird. Hierdurch ist eine Montage des Laufrades am Kühlgutträger ohne jegliche Hinzunahme von Werkzeug möglich.According to the invention, the impeller has essentially two components, an axle stub serving as axle element and a roller which runs on the axle element and engages in the rails, wherein the axle element has latching elements which fix the axle element to the refrigerated goods carrier, a rail arranged thereon. or at the recess on the refrigerated goods through which the axle member passes and / or serve to fix the roller on the axle. Due to the locking elements, the axle of the impeller simply snaps into a recess provided for the refrigerated goods as soon as it is passed through this. As a result, an assembly of the impeller on refrigerated goods without any addition of tools is possible.

An dem Achselement des Laufrades ist wenigstens ein weiteres Rastelement vorgesehen, das der Halterung der Rolle dient. Hierdurch kann auch die Laufrolle einfach auf das Achsenelement aufgesteckt werden. Dadurch wird eine Montage des gesamten Laufrades an sich und am Kühlgutträger völlig ohne Zusatzwerkzeug ermöglicht.On the axle of the impeller at least one further locking element is provided which serves to hold the roller. As a result, the roller can be easily attached to the axle element. This will be an assembly allows the entire impeller itself and the refrigerated goods without any additional tool.

In einer bevorzugten Ausführungsform sind die Rastelemente vorspringend als Rastnasen, Rastwülste, Rasthaken oder ähnliches ausgebildet. Diese können an geeignete dafür vorgesehene Stellen am Kühlgutträger und/oder der Rolle eingreifen, um dadurch eine stabile Halterung des Systems zu bewirken. Produktionstechnisch lassen sich vorspringende Rastelemente einfacher an dem Achsenelement realisieren als an Kühlgutträger oder Rolle. Außerdem sind Vorsprünge an Achsenelement zu bevorzugen, denn z.B. das Vorsehen von Nuten im Achsenelement würde die gleichmäßige Festigkeit und Stabilität des Achsenelements beeinträchtigen.In a preferred embodiment, the locking elements are projecting formed as locking lugs, Rastwülste, latching hooks or the like. These can engage at appropriate locations provided on the refrigerated goods and / or the role, thereby causing a stable support of the system. In terms of production, projecting locking elements can be realized more easily on the axle element than on refrigerated goods carriers or rollers. In addition, protrusions on the axis element are preferable, e.g. the provision of grooves in the axle member would compromise the uniform strength and stability of the axle member.

Prinzipiell läßt sich die Erfindung jedoch durch jede Kombination von Rastnuten und Rastnasen realisieren.In principle, however, the invention can be realized by any combination of locking grooves and locking lugs.

In einer bevorzugten Ausführungsform weist das Achselement vorspringende Rastelemente in dem Bereich auf, der der Befestigung des Achselements am Kühlgutträger dient. Dieser Bereich ist vorzugsweise im Verhältnis zum Lagerbereich der Laufrolle verbreitert, um eine sichere Halterung zu bewährleisten ohne verschleißanfällig zu sein. Diese Vorsprünge sind so angeordnet, dass sie in montiertem Zustand die Wand des Kühlgutträgers umfassen, das heißt, die Wand der Aussparung des Kühlgutträgers wird zwischen den Vorsprüngen des Rastelements eingeklemmt, so dass das Achsenelement nicht mehr in axialer Richtung bewegbar ist. Zur Montage des Laufrades muss also lediglich einer der Vorsprünge des Befestigungsbereiches des Achsenelements durch die Aussparung durchgedrückt werden, so dass er als Gegenstück zum vor der Aussparung verbleibenden Vorsprung das Achsenelement an der Wand des Kühlgutträgers fixiert. Der hindurchtretende Vorsprung ist aus diesem Grund nur gering gegenüber dem Radius der Aussparung hervortretend ausgebildet während der verbleibende Vorsprung in seiner Größe nicht beschränkt ist und deshalb größer ausgebildet ist um eine sicherere Halterung zu gewährleisten.In a preferred embodiment, the axle element has projecting latching elements in the region which serves to fasten the shaft element to the refrigerated goods carrier. This area is preferably widened in relation to the bearing area of the roller in order to assure a secure mounting without being susceptible to wear. These projections are arranged so that they comprise the wall of the refrigerated goods carrier in the assembled state, that is, the wall of the recess of the refrigerated goods carrier is clamped between the projections of the latching element, so that the axis element is no longer movable in the axial direction. To mount the impeller so only one of the projections of the mounting portion of the axle member must be pushed through the recess so that it fixes the axle member on the wall of the refrigerated goods as a counterpart to the projection remaining in front of the recess. The protruding projection is for this reason only slightly formed with respect to the radius of the recess protruding while the remaining projection is not limited in size and therefore larger in size to ensure a more secure support.

Im Achsbereich des Achsenelements, auf dem die Rolle gelagert ist, ist ein weiterer Vorsprung vorgesehen, der so geformt ist, dass er über den Radius des Achsloches hinaustritt. Damit kann er die Rolle auf dem Achsenelement festhalten. Dies geschieht entweder indem er in eine hierfür vorgesehene Nut im Inneren des Achslochs der Rolle oder in die äußere Seitenwand der Rolle eingreift sobald die Rolle auf den Achsbereich des Achsenelements aufgesteckt ist. Da er beim Montieren durch die Rolle hindurchtreten muss, darf er jedoch nicht zu hervorstehend ausgeführt sein. Durch einen derartigen leicht erhöhten Vorsprung, über den sich die Rolle einfach auf das Achselement aufschieben läßt, kann die Rolle gehaltert werden, ohne dass ein weiterer Befestigungsmechanismus für sie vorzusehen wäre.In the axis region of the axle element on which the roller is mounted, a further projection is provided, which is shaped so that it extends beyond the radius of the axle hole. So he can do the role on the Hold axle element. This is done either by engaging in a groove provided for this purpose in the interior of the axle hole of the roller or in the outer side wall of the roller as soon as the roller is attached to the axle region of the axle element. However, as it has to pass through the roller during assembly, it must not be too protruding. By such a slightly raised projection over which the role can be easily postponed on the axle, the role can be held without a further attachment mechanism would be provided for them.

In einer bevorzugten Ausführungsform sind vor allem die Vorsprünge, welche bei der Montage durch die Aussparung des Kühlgutträgers bzw. das Achsloch der Rolle hindurchtreten müssen ringförmig ausgebildet, so dass sie das Achsenelement wenigstens bereichsweise ringförmig umgeben. In dieser Ausführungsform können sie, da sie möglichst viel Berührungsfläche bei möglichst geringer radialer Ausdehnung bieten, ihrer Haltefunktion gut nachkommen, ohne beim Durchtreten der Aussparungen bzw. des Loches bei der Montage zu stark beansprucht zu werden.In a preferred embodiment, the projections, which must pass through the recess of the refrigerated goods carrier or the axle hole of the roller during assembly, are designed to be annular, so that they surround the axle element at least in regions in an annular manner. In this embodiment, since they offer as much contact surface as possible with the smallest possible radial extent, they can perform well with their holding function without being subjected to excessive stress during the passage through the recesses or the hole during assembly.

Vorzugsweise ist das Achsenelement hohl, so dass ihm eine gewisse Elastizität zu eigen ist, die ein Niederdrücken der Vorsprünge bei der Montage ermöglicht.Preferably, the axis element is hollow, so that it has a certain elasticity, which allows a depression of the projections during assembly.

Die Elastizität wird bevorzugt dadurch unterstützt, dass das Achsenelement vor allem im Befestigungsbereich Aussparungen aufweist, welche das Achsenelement zumindest bereichsweise in wenigstens zwei Segmente teilt, welche aufeinander zu bewegt werden können.The elasticity is preferably supported by the fact that the axle element, especially in the attachment area, has recesses which at least partially divide the axle element into at least two segments which can be moved towards one another.

Diese Aussparungen am Achsenelement dienen vorzugsweise ferner der Aufnahme von Nasen, welche zur Verdrehsicherung an die Aussparung des Kühlgutträgers durch die das Achsenelement bei der Montage hindurchtritt angebracht sind. Diese Freiräume des Achsenelements erfüllen also eine Doppelfunktion, sie dienen zum einen der Elastizität des Achsenelements, die notwendig ist um die Rastelemente am Kühlgutbehälter in Eingriff zu bringen und gewährleisten weiterhin die Verdrehsicherung des Laufrades indem sie als Gegenstücke zu am Kühlgutträger angebrachten Vorsprüngen fungieren.These recesses on the axle element preferably also serve to receive lugs, which are attached to prevent rotation of the recess of the refrigerated goods through which the axle element passes during assembly. These free spaces of the axle element thus fulfill a dual function, they serve on the one hand the elasticity of the axle element, which is necessary to bring the locking elements on Kühlgutbehälter into engagement and continue to ensure the rotation of the impeller by acting as counterparts to the Kühlgutträger mounted projections.

In einer weiteren bevorzugten Ausführungsform ist das Achsloch der Rolle konisch geformt. Diese Form dient der einfacheren Montierbarkeit der Rolle auf dem Achsenelement, da sie das Durchtreten des die Rolle fixierenden Vorsprunges erleichtert.In a further preferred embodiment, the axle hole of the roller is conically shaped. This shape is used to simplify the mountability of the roller on the axle element, as it facilitates the passage of the roller fixing the projection.

Auch der Achsenbereich des Achsenelements, der der Lagerung der Rolle dient ist bevorzugt zumindest bereichsweise konisch geformt, so dass die Rolle nicht nur auf einem Ring sondern auf einer gegengleich geformten Fläche des Achsenelements zu liegen kommt. Dadurch kann vorzeitiger Verschleiß des Achsenelements verhindert und ein gleichmäßigeres Laufen der Rolle gewährleistet werden.Also, the axis region of the axle member, which serves to support the roller is preferably at least partially conically shaped, so that the role not only on a Ring but comes to rest on a counter-shaped surface of the axis element. As a result, premature wear of the axle element can be prevented and a more uniform running of the roller can be ensured.

Die Erfindung besteht also darin, das Laufrad aus im wesentlichen zwei Teilen aufzubauen, wobei ein Teil eine Rolle ist und das andere Teil als Achsenelement ausgeformt ist, welches im wesentlichen einen Lagerbereich für die Rolle und einen Befestigungsbereich zum befestigen des Laufrades an dem Kühlgutträger aufweist. Beide Elemente können einfach aus Kunststoff, beispielsweise in einem Spritzgußverfahren, hergestellt werden. An dem Achsenelement sind Rastelemente angebracht, die der Befestigung des Laufrades am Kühlgutträger und der Verbindung von Rolle und Achsenelement dienen. Ein derartiges Laufrad kann ebensogut am Kühlgutbehälter wie an einer am Kühlgutbehälter befestigten Schiene montiert werden. Prinzipiell wäre es auch möglich zur Verdrehsicherung Rastnasen am Achsenelement vorzusehen und den Kühlgutträger mit den zugehörigen Aussparungen zu versehen.The invention thus consists in constructing the impeller from essentially two parts, one part being a roller and the other part being formed as an axle element, which essentially has a bearing area for the roller and a fastening area for fastening the wheel to the refrigerated goods carrier. Both elements can be easily made of plastic, for example in an injection molding process. On the axle element locking elements are mounted, which serve the attachment of the impeller on Kühlgutträger and the connection of the roller and axle element. Such an impeller can just as well be mounted on the refrigerated goods container as on a rail attached to the refrigerated goods. In principle, it would also be possible to provide locking lugs on the axle element and to provide the refrigerated goods carrier with the associated recesses.

Die Figur 1 zeigt eine schematische Schnittdarstellung durch ein Kältegerät 1 mit einem erfindungsgemäßen Kühlgutträger 2, der in diesem Beispiel im unteren Bereich des Kältegerätes 1 angeordnet ist. Der Kühlgutträger 2 weist einen Kühlgutbehälter 3 auf, welcher über einen in dieser Abbildung nicht sichtbaren Teleskopauszug an einem als Fachboden ausgebildeten Trägerelement 4 angeordnet ist. Im stirnseitigen Bereich ist der Kühlgutbehälter 3 mit einer Abdeckung 5, welche schwenkbar am Trägerelement 4 gelagert ist, versehen. Auf dem als Fachboden ausgebildeten Trägerelement 4 befinden sich Führungselemente 6, die als Führung für die Rollen 7 dienen, auf denen die ausfahrbaren Kühlgutbehälter 8 und 9 bewegt werden können. Oberhalb der Kühlgutbehälter 8 und 9 ist ein weiterer Fachboden 10 auf Haltestegen 11 angeordnet. Auch das als Fachboden ausgebildete Halteelement 4 ist auf derartigen in der Abbildung durch die Abdeckung 5 verdeckten Haltestegen 11 am Kältegerät 1 befestigt. Der ausziehbare Kühlgutträger 2 steht also über gängige Haltestege 11 des Kältegeräts 1 mit diesem in Verbindung und kann an beliebigen Positionen im Kältegerät 1, an denen sich derartige Haltestege 11 befinden, angeordnet werden.The FIG. 1 shows a schematic sectional view through a refrigerator 1 with a refrigerated goods according to the invention 2, which is arranged in this example in the lower part of the refrigerator 1. The refrigerated goods carrier 2 has a refrigerated goods container 3, which is arranged on a not visible in this figure telescopic extension to a tray formed as a tray element 4. In the frontal region of the refrigerated goods container 3 with a cover 5, which is pivotally mounted on the carrier element 4, provided. On the carrier element 4 designed as a shelf are guide elements 6, which serve as a guide for the rollers 7, on which the extendable refrigerated goods containers 8 and 9 can be moved. Above the refrigerated goods 8 and 9 another shelf 10 is arranged on retaining webs 11. Also formed as a shelf holding element 4 is mounted on such hidden in the figure by the cover 5 retaining webs 11 on the refrigerator 1. The extendable refrigerated goods 2 is therefore on common support webs 11 of the refrigerator 1 with this in conjunction and can be placed at any position in the refrigerator 1, where such holding webs 11 are located.

Der Aufbau des ausziehbaren Kühlgutträgers 2 ist in Figur 2 im Detail dargestellt. Hier wird mittels einer perspektivischen Darstellung der Aufbau des Kühlgutträgers 2 noch einmal verdeutlicht. Der Kühlgutträger besteht im wesentlichen aus dem Kühlgutbehälter 3, auf den das als Fachboden ausgebildete Trägerelement 4 über ein in der Figur 1 nicht sichtbares Seitenteil 12 aufgesetzt ist. An dem Trägerelement 4 ist eine stirnseitige Abdeckung 5 des Kühlgutbehälters 3 schwenkbar befestigt. Das Seitenteil 12 weist Rasthaken 13 auf, welche in hierfür vorgesehene, in dieser Figur nicht sichtbare, Rastlöcher in dem Halteelement 4 einhaken um das Seitenelement 12 fest mit dem Halteelement 4 zu verbinden. Ferner weist das Seitenteil 12 ebenso wie das nicht dargestellte gegengleich aufgebaute Seitenteil der anderen Seite ein Festschienenteil 14 auf, welches an der Innenseite des Seitenteiles 12 verläuft und hier nur schematisch angedeutet ist. Dieses Festschienenteil 14 ist Bestandteil des Teleskopauszugs, der das Herausziehen des Kühlgutbehälters 3 ermöglicht. Das Gegenstück zu diesem Festschienenteil 14 ist ein am Kühlgutbehälter 3 angeordnetes Losschienenteil 15. Sowohl am Seitenteil 12 als auch am Kühlgutbehälter 3 sind Rollen 16 und 17 angeordnet, welche in den durch die Schienen 14 und 15 gebildeten Laufkanälen laufen. Die Rolle 18 läuft in dem Festschienenteil 14, in den der Kühlgutbehälter 3 eingehängt ist. Die Schiene 15 dient dabei als obere Führung für die Rolle 16 und bietet außerdem mittels des, als Bestandteil der oberen Schiene 15, ausgebildeten Anschlages 19 eine Stoppfunktion, die ein Herabkippen bzw. Herausfallen des Kühlgutbehälters 3 aus dem Kältegerät 1 verhindert. Diese Funktionsweise sowie die Entnahme des Kühlgutbehälters 3 vom Halteelement 4 sind in den Figuren 3 und 4 erläuternd dargestellt. Die Abdeckung 5 ist am Halteelement 4 schwenkbar gelagert und wird mittels eines nicht näher erläuterten, dem Fachmann jedoch bekannten Schwenkmechanismus automatisch nach oben geschoben, sobald der Kühlgutbehälter 3 nach vorne gezogen wird. Ein derartiger Schwenkmechanismus, der ein automatisches Hochdrücken der Abdeckung 5 bewirkt, kann beispielsweise durch die Form bedingt sein, in der die Abdeckung 5 und der Kühlgutbehälter 3 in dem Bereich ausgebildet ist in dem sie ineinander greifen.The structure of the extendable refrigerated goods carrier 2 is in FIG. 2 shown in detail. Here, the construction of the refrigerated goods carrier 2 is clarified once again by means of a perspective view. The refrigerated goods carrier consists essentially of the refrigerated goods container 3, on which the tray element formed as a support element 4 via a in the FIG. 1 not visible side part 12 is placed. On the support member 4, an end cover 5 of the refrigerated goods container 3 is pivotally mounted. The side part 12 has latching hooks 13, which hook into this, not visible in this figure, detent holes in the holding element 4 to hook the side member 12 fixed to the support member 4. Furthermore, the side part 12 as well as the opposite side wall part of the other side, not shown, a fixed rail part 14, which extends on the inside of the side part 12 and is indicated here only schematically. This fixed rail part 14 is part of the telescopic extension, which allows the extraction of the refrigerated goods container 3. The counterpart of this Festschienenteil 14 is an am Refrigerated goods 3 arranged loose rail part 15. Both the side part 12 and the refrigerated goods 3 rollers 16 and 17 are arranged, which run in the channels 14 and 15 formed by the channels. The roller 18 runs in the fixed rail part 14, in which the refrigerated goods container 3 is mounted. The rail 15 serves as an upper guide for the roller 16 and also offers by means of, formed as part of the upper rail 15, stop 19 a stop function that prevents a dropping or falling out of the refrigerated goods container 3 from the refrigerator 1. This mode of operation and the removal of the refrigerated goods container 3 from the holding element 4 are in the FIGS. 3 and 4 illustrated. The cover 5 is pivotally mounted on the support member 4 and is automatically pushed upwards by means of an unspecified, but the person skilled in the known pivot mechanism as soon as the refrigerated goods 3 is pulled forward. Such a pivoting mechanism, which causes an automatic push-up of the cover 5, for example, may be due to the shape in which the cover 5 and the refrigerated goods container 3 is formed in the region in which they interlock.

In Figur 3 ist ein Ausschnitt des in seiner Endstellung vollständig geöffneten Kühlgutträgers 2 schematisch dargestellt. Das Seitenteil 12 ist mit dem Trägerelement 4 über die hier nicht sichtbaren Rastnasen 13 verbunden und weist ein Festschienenteil 14 auf, das an der Innenseite des Seitenteils 12 verläuft. Der Kühlgutbehälter 3 mit seinem Losschienenteil 15 ist in der dargestellten Position soweit herausgefahren, dass der Anschlag 18, der Bestandteil des Kühlgutbehälters 3 ist, die Rolle 16 des Festschienenteils 14 berührt. Ein weiteres Herausfahren des Kühlgutbehälters 3 ist in dieser Stellung nicht mehr möglich. Die Rolle 17 als Bestandteil des Kühlgutbehälters 3 verhindert durch ein Abstützen an der Unterseite der oberen Schiene 19 des Festschienenteils 14 ein Kippen des Kühlgutbehälters 3 in dieser Position.In FIG. 3 is a section of the fully opened in its end position refrigerated goods carrier 2 shown schematically. The side part 12 is connected to the carrier element 4 via the locking lugs 13, which are not visible here, and has a fixed rail part 14 which runs on the inside of the side part 12. The refrigerated goods container 3 with its loose rail part 15 is brought out in the position shown so far that the stop 18, which is part of the refrigerated goods container 3, the roller 16 of the fixed rail part 14 touches. Further retraction of the refrigerated goods container 3 is no longer possible in this position. The roller 17 as part of the refrigerated goods container 3 prevented by a support on the underside of the upper rail 19 of the fixed rail member 14, a tilting of the refrigerated goods container 3 in this position.

Die Figur 4 zeigt schematisch die Entnahmeposition des Kühlgutbehälters 3 des in Figur 3 ausschnittsweise dargestellten Kühlgutträgers 2. Nach Überfahren der Rolle 16 des Festschienenteils 14 durch den Anschlag 18 des Kühlgutbehälters 3 ist eine Entnahme dieses möglich. Die Entnahme des Kühlgutbehälters 3 erfolgt durch ein horizontales Kippen bei gleichzeitigem Überfahren der Rolle 16 durch die Rolle 17, die Bestandteil des Kühlgutbehälters 3 ist. Hierzu ist die Einführschiene 20, die vorzugsweise eine Verlängerung der oberen Schiene 19 darstellt und fest mit ihr verbunden ist, so ausgeformt, dass sie in einer elliptischen Bahn nach oben schwenkt, wodurch sie die Breite des Laufkanals 30 vergrößert und dadurch das Überfahren der Rolle 16 durch die Rolle 17 zulässt.The FIG. 4 schematically shows the removal position of the refrigerated goods 3 of the FIG. 3 After passing over the roller 16 of the fixed rail part 14 through the stop 18 of the refrigerated goods 3, a removal of this is possible. The removal of the refrigerated goods 3 is carried out by a horizontal tilting while driving over the roller 16 by the roller 17, which is part of the refrigerated goods 3 is. For this purpose, the insertion rail 20, which preferably represents an extension of the upper rail 19 and is fixedly connected to it, is formed so that it pivots in an elliptical path upward, thereby increasing the width of the running channel 30 and thereby driving over the roller 16 through the roller 17 allows.

Die Figur 5 zeigt eine Explosionszeichnung, die Figur 6 eine Schnittzeichnung des in dem oben beschriebenen, herausziehbaren Kühlgutträger 3 montierten Achsstummels 21 mit der zugehörigen Laufrolle 28. Der Achsstummel 21 hat eine Anlauffläche 23, die in montiertem Zustand an der Innenseite und eine Gegenfläche 24, die an der Außenseite des Kühlgutbehälters 3 zu liegen kommt. Eine Bohrung 26 im Kühlgutbehälter 3 besitzt zwei sich gegenüber liegende Nasen 27. Diese zwei Nasen 27 greifen bei der Montage des Achsstummels 21 in seitlich entlang des Achsstummels 21 verlaufende Aussparungen 22 und unterbinden damit eine Verdrehung des Achsstummels 21. Der Achsstummel 21 verfügt über einen Lagerkonus 31, einen Einführzylinder 32, eine Wulst 25 sowie zwei bis zum Beginn des Lagerkonus 31 reichende Aussparungen 22. Der Lagerkonus 31 stellt die direkte absatzlose Verlängerung des Einführzylinders 32 dar. Die einfache Montierbarkeit des Achsstummels 21 in den Kühlgutträger 3 ist durch seine Ausbildung als Hohlkörper, die Elastizität seines gewählten Werkstoffs sowie durch die Länge der zwei Aussparungen 22 des Achsstummels 21 gegeben. Die Laufrolle 28 besitzt einen Achskonus 33. Die Werkstoffe des Achsstummels 21 und der Laufrolle 28 bilden eine Gleitpaarung. Die Winkel des Achskonus 33 und des Lagerkonus 31 sind gleich und dadurch bestimmt, dass sich die Wulst 25 des Achsstummels 21 annähernd kraftlos bis zu der Lage in den Achskonus 33 der Laufrolle 28 einschieben lässt, ab der in montiertem Zustand der Achskonus 33 auf dem Lagerkonus 31 aufliegt. Dadurch, dass die Aussparungen 22 am Beginn des Lagerkonus 31 enden, ist der Lagerkonus 31 geschlossen geformt und hat damit ausreichende Festigkeit, Kräfte, die im Betrieb auf die Laufrolle 28 wirken werden, aufzunehmen, ohne sich zu verformen. Die Wulst 25 ist an der Einführseite gerundet geformt, so dass beim Montieren der Laufrolle 28 kein Verschleiß der Wulst 25 auftritt. Durch die Werkstoffelastizität des Achsstummels 21 wird bei der Montage der Laufrolle 28 die Wulst 25 durch den Achskonus 33 so weit zusammengepresst, dass sie durch den Achskonus 33 rutscht und sich danach entspannt. Dieser Vorgang führt dazu, dass die Laufrolle 28 unverlierbar auf dem Achsstummel 21 sitzt.

The stub axle 21 has a stop surface 23, which comes to rest in the mounted state on the inside and a counter surface 24 which lies on the outside of the refrigerated goods , A bore 26 in the refrigerated goods container 3 has two opposing lugs 27. These two lugs 27 engage in the assembly of the stub axle 21 in laterally along the stub axle 21 extending recesses 22 and thus prevent rotation of the stub axle 21. The stub axle 21 has a bearing cone 31, an insertion cylinder 32, a bead 25 and two reaching to the beginning of the bearing cone 31 recesses 22. The storage cone 31 represents the direct paragraph extension of the Einführzylinders 32. The easy mountability of the stub axle 21 in the refrigerated goods 3 is due to its design as a hollow body , given the elasticity of its chosen material and by the length of the two recesses 22 of the stub axle 21. The roller 28 has an axial cone 33. The materials of the stub axle 21 and the roller 28 form a sliding pair. The angles of the axial cone 33 and the bearing cone 31 are the same and determined by the fact that the bead 25 of the stub axle 21 can be inserted almost without power up to the position in the axial cone 33 of the roller 28, from the mounted in the axial cone 33 on the bearing cone 31 rests. Characterized in that the recesses 22 terminate at the beginning of the bearing cone 31, the bearing cone 31 is formed closed and thus has sufficient strength to absorb forces that will act on the roller 28 in operation, without deforming. The bead 25 is rounded at the insertion side, so that when mounting the roller 28 no wear of the bead 25 occurs. Due to the material elasticity of the stub axle 21, the bead 25 is compressed by the axial cone 33 during assembly of the roller 28 so far that it slips through the axial cone 33 and then relaxes. This process causes the roller 28 captive on the stub axle 21 sits.
